Acrylamide
This is an odorless chemical intermediate product in the synthesis of polyacrylamides. These high molecular weight polymers are used primarily as additive for water treatment where it removes suspended solids from industrial wastewater before discharge, reuse, or disposal. An epidemiological study by Roselino AM et al and published in the International Journal of Dermatology 35(3):181-4,1996 described seven cases of alopecia areata among workers in the Water and Effluent Treatment Sector (WETS) of a paper factory. The number represented a 0.6% Incidence, when the value for the population at large is 0.1%. Toxicologic evaluation revealed an acrylamide-like substance in the 7 workers with alopecia areata in contrast to 1 out of 11 controls. The authors suggested a statistically significant correlation eventhough the study did not correct for the large number of comparisons. Laboratory studies for other putative agents (e.g., bacteria, fungi, peticides, and heavy metals) were negative. More information about acrylamide may be found at the web site of the National Safety Council.
Addison's disease
A disease characterized by low blood pressure, and a brownish coloration of the skin due to decreased secretion of the hormone cortisol from the adrenal gland. Areas of hyperpigmentation may be generalized or limited to skin folds such as the creases of the hands and scars.
Adrenal glands
The adrenal glands sit atop the kidneys, and are responsible for producing cortisol (the human steroid) as well as a hormone which regulates water levels in the body (aldosterone).
Aloe vera
There are over 200 different varieties of aloe vera and product processing may change the extract natural properties. Aloe comes in gel, distilled liquid or "juice" (used for constipation and other colon problems), as an extract, and even reconstituted. It's very confusing.

The extracts of the aloe vera plant have a complex set of chemicals with the ability to suppress and stimulate the immune system in a number of ways. There are reports of clinical trials, of varying quality, suggesting that aloe vera has a positive effect on wound healing, immune stimulation, aalso aginast cancerc and in the treatment of various viral conditions. There is also a recent report of its effectiveness in the treatment of psoriasis.

Alopecia
Hair loss (alopecia) can be separated into different classes according to whether it is scarring or nonscarring, diffuse or patchy. In scarring alopecia, the hair follicles are involved by inflammation. The attendant fibrosis and loss of hair follicles prevents any potential regrowth. Scarring is manifested by a pale, glazy and smooth scalp. Examples of scarring alopecia include discoid lupus erythematosus, acne keloidales nuchae, morphea, burns/radiation, and chronic infections. Most patients in clinical practice are classified as having a nonscarring alopecia. This type includes alopecia areata, androgenetic alopecia, telogen effluvium, traction alopecia, trichotillomania, secondary syphilis, endocrine, drug/chemo, and nutrition. The alternative classification of diffuse hair loss includes androgenetic alopecia, telogen efluvium, endocrine, nutirtional, frug, and rare cases of alopecia areata. Types of patchy hair loss include alopecia areata, fungal infection (tinea capitis), discoid lupus, traction, and acne keloidalis nuchae.
Ames test
The Ames test has been around for some time. Its purpose is to test chemicals as potential carcinogens by their ability to mutate bacteria. The government uses it because it is quick, simple and relatively cheap. If a chemical proves positive with an Ames test, animal studies are then performed. The test itself is "in vitro" and uses a lower species, making any results difficult to extrapolate to humans. Among the topical immunotherapeutic recommended for patients with alopecia areata, DNCB has proven carcinogenic. This is no longer a therapeutic option to consider.
Anagen
The active growing phase of the life cycle of the hair. It lasts approximately for 3 years with a range of 2-6 years.
Anthralin
A chemical irritant with an extensive history of use in psoriasis. It produces irritation and discoloration of the skin and is often used in combination with tars and ultraviolet radiation (see section 6 for chemical irritants). In psoriasis it helps control the rapid growth of skin cells. Some people believe that in alopecia it works by competitive inhibition, i.e., it causes so much inflammation that the "bad" white cells present can't do their damage.

Anthralin is available as a greasy ointment (Anthraderm) and also as a non-greasy vanishing cream (Dritbo, Lasan). Whether drithocreme or micanol (types of anthralin) are more effective, if at all, is unclear to me. Studies show anthralin works from 0-82% of the time! It is applied to the bare patches once daily and washed off after a short time, usually 30-60 minutes later. If new hair growth occurs, it is seen in eight to twelve weeks.

Antibiotics
Treatment of alopecia areata with antibiotics goes way back to the time when its origin was thought to be infectious. Another theory was that dental infections caused the disease. Shelley and Shelley, MD's in Ohio began popularizing antibiotic treatment of alopecia areata in the past decade. Lutz, MD found AA patients had high levels of ASO and antiDNAse antibodies, suggesting a streptococcal origin or prompt. It is unclear how effective treatment with antibiotics is in alopecia areata.
Antimicrosomal antibodies
There is a blood test for "antithyroid microsomal antibody." It also goes by other similar names: antimicrosomal antibody; microsomal antibody, thyroid autoantibody, thyroid antimicrosomal antibody. Microsome is defined as "any of the vesicular fragments of endoplasmic reticulum formed after disruption and centrifugation of cells." Whatever it's called, the test is to detect thyroid "microsomal" antibodies. Approx. 70-90% of people with Hashimoto's thyroiditis have the antibodies; but another 5-10% of "healthy" people also have them -- their titer (count) is low.

According to Mosby's diagnostic and laboratory test reference, "Microsomal antibodies are produced in response to microsomes escaping from the epithelial cells surrounding the thyroid follicle. These escaped microsomes then act as antigens and give rise to antibodies. These immune complexes initiate inflammatory and cytotoxic effects on the thyroid follicle. This test is usually performed in conjunction with the antithyroglobulin antibody test."

Antinuclear antibodies (ANA)
As the name suggests ANA's are immunoglobulins (antibodies) directed against different constituents of the nucleus of a cell. Under the microscope, cells reacting with these antibodies exhibit different staining patterns. In some, staining of the nucleus occurs in a uniform fashion, in others only the margins of the nucleus are apparently involved, there is also a speckled pattern, etc.. When the clinician interprets the laboratory tests, he takes into consideration both the pattern and the amount (titer) of these antibodies. Very high numbers of these antibodies staining the nuclei of cells in a speckled fashion have been associated with systemic lupus erythematosus. High titers staining the nuclei of cells in a dot-like configuration (nucleoli) are suggestive of scleroderma and polymyositis. Because of the variabile expression, the test results should be done primarily by a specialist. Occasionally positive ANA's have been reported in completely normal individuals (a false positive), in aged individuals, patients with a positive family history of autoimmune disease, and in patients suffering from other chronic conditions (e.g.., several rheumatic, autoimmune, and inflammatory arthritides). Some of these conditions include Sjogren's syndrome, chronic active hepatitis, autoimmune thyroiditis, lymphoproliferative disorders, chronic bronchitis, tuberculosis, pernicious anemia, ulcerative colitis, myasthenia gravis, and infectious mononucleosis. Positive readings can also occur as a result of numerous drugs, including "simple" ones like penicillin, tetracyclines, streptomycin. At the other end of the spectrum, *false* negative readings can occur as a result of using steroids.

The problem with having a disease characterized by antibodies against nuclei is that ALL cells of the body have this structure. The disease may therefore affect the brain as well as the kidney, or the joints. In other autoimmune conditions the antibodies are directed against a portion of a specialized cell and may therefore be restricted to a specific tissue type (e.g., skin).

Antithryglobulin antibodies
Antithyroglobulin antibody - has other names, like thyroid autoantibody, etc.) can also show up in Hashimoto's thyroiditis (about 50% of patients). But, abnormally high levels can also indicate hypothyroidism, rheumatoid arthritis, pernicious anemia, etc. (See also antimicrosomal antibodies). Hairloss is a common symptom of thyroid disorders. Antithyroglobulin antibodies is part of the laboratory testing used to establish the diagnosis of thyroid disorder.
Apoptosis
From the Greek words "apo" meaning off and "ptosis" to fall. Apoptosis or falling off is a type of cell suicide or programmed death. This type of cell death occurs by fragmentation of membranes that are then eliminated by phagocytosis. Several articles claim that apoptosis is a possible mechanism mediating cell death in both androgenetic type alopecia and alopecia areata.
Aromatherapy

“I'm still using the aromatherapy oil on my head. Smells better than olive oil. I really don't know how much difference either actually makes, but I do have an itching problem in my scalp as well, and the aromatherapy soothes the itching somewhat.”

An article about aromatherapy and alopecia appeared in Natural Health September/October 1997 issue. In the article, a women who suffered from AA since children and was losing all of her hair, recounted her use of aromatherapy and cayenne extract. Each night before bed, she massaged a mixture of lemon, lavender, rosemary and carrot seed essential oils in a base of jojoba oil into her scalp (no information as to the total amount of each mixed was provided). In the morning, she stimulated her scalp with cayenne pepper extract and a soft toothbrush followed by rinses of hot and cold water. She claims to have seen regrowth in about three months and had a full head of hair after six months. She has not had a recurrence of alopecia since beginning her therapy.

In "The Complete Book of Essential Oils and Aromatherapy" by Valerie Ann Worwood several recepies are recommended using oils:

Alopecia Shampoo

Blend ingredients together in a bainmarie and use the shampoo once a week.

  • Soap stew 4 ounces
  • Jojoba Oil 12 drops
  • Carrot Oil 6 drops
  • Rosemary 6 drops
  • Lavender 10 drops

Alopecia Conditioner

Blend the ingrediants together and massage into scalp. Leave on the hair at least 30 min. before washing off.

  • Jojoba oil 1/2 teaspoon
  • Evening primrose 10 drops
  • Palma Rosa 3 drops

At night time

Every night apply the following treatments all over the scalp. Mix together and store in bottle. Use 1 teaspoon for each application diluted in 1 tablespoon of cold cold water. This one doesn't smell to great and your husbands/boyfriends may not want to sleep next to at night

  • Cider vinegar 4 ounces
  • carrot oil 20 drops
  • Rosemary 10 drops

In the book it states, "Essential oils, and indeed many nut oils can stimulate the hair follicle and increase circulation and oxidization sufficiently to bring regrowth of hair, although in some cases this may resemble vellus or baby hair".

Some of our members have used the following recipe with some success:

  • 1 tbls. Jojoba oil
  • 1 tbls. Calendula infusion oil
  • 1/2 tsp. Carrot seed oil
  • 10 drops Lavender essential oil
  • 6 drops Clary sage essential oil
  • 4 drops Cedarwood essential oil
  • 4 drops Rosemary essential oil

In a small amber glass bottle, add the jojoga oil and carrot seed oil. Add the essential oils and shake to mix. Label. Warm the oil before application by placing it in a warm water bath. Apply by massaging a few drops into the scalp area. Leave in to be absorbed. Apply several times weekly.

Note: Small amounts of essential oils are used with the same amount of carrier oils for children. Example: where ever you read essential oils you must cut drop amount in half. Rosemary would then be 2 drops. Carrot seed oil is hard to find, expensive but a very good oil for hair problems. Calendula oil must be made by infusion (made from actual herb sitting in olive oil in the sun for about three weeks, shake from time to time.

Of related interest is an extract from the book "Herbs: Their Cultivation and Usage":

Lavender
It is claimed that rubbing oil of lavender on burns does not relieve the pain, but assists in healing scar tissue. Calms the nerves and relaxes tensions. Has a good effect on digestion. Lavender and valerian have both been recommended for people having trouble sleeping.
Rosemary
Rosemary's main attribute is its association with all functions of the head. Extract of rosemary in shampoos and hair tonics revitalizes the scalp, prevents dandruff and encourages new and healthy hair growth with a shining lustre.

For people with sensitive skin some great non-irritating soap recipes can be found in Sandy Maine's "The Soap Book". One of the recipes is made of lavender and rosemary essential oils and comfrey root powder.

The scientific community has joined the aromatherapy bandwagon. A recent article by Hay, Isabelle, et. al. "Randomized trial of aromatherapy: successful treatment for alopecia areata." Archives of Dermatology. Vol. 134. November 1998. 1349-1352 focuses attention on this possible therapeutic intervention. The researchers in the study used a mixture of cedarwood, thyme, lavender, rosemary, jojoba, and grapeseed oils. The mixture was massaged in the scalp of patients every evening for two minutes. A placebo control group received only jojoba and a grapeseed oil mixture. To be honest, when you have a good look at the study, there are holes in it, and the title of the article is a little over optimistic. It does not mention how long people had areata, how they randomized the groups, and whether or not they had other associated disorders. Sometimes aassociated conditions (such as thyroid disorders) are a factor in a positive or negative outcome.

For those people who have tried aromatherapy, it smells too much and doesn't work all that well. What they would like is aromatherapy without the aroma!!! Additional information about this therapy can be found in a newsletter called The Integrative Medicine Consult (February 1, 1999 Volume 1, Number 4). If you would like to try it the following are some suggested dosages:

  • Active oils: 2 drops (88mg), Thyme (Thyme vulgaris); 3 drops (108mg), Lavendar (Lavendula agusifola); 3 drops (114mg), Rosemary (Rosmarinus officinalis); 2 drops (114mg), Cedarwood (Cedrus atlantica)
  • Inactive carrier oils: 3mL jojba oil; 20mL grapeseed oil. Grapeseed oil is very slippery and not well absorbed into the scalp. It may have been used as a carrier because it is very cheap.
  • Massage into scalp each evening for a minimum of 2 minutes; follow with warm towel wrap to aid absorption of oils. Aromatherapists recommend giving 1/3 to 1/2 of the dose for children under 12.

Avoid using red thyme, one of the various types of thyme. This is a potent counter irritant and will burn the scalp. This kind of thyme used with one of the better (more expensive) and more irritating forms of rosemary causes scarring. Of the scarring types of thyme- one drop can be used per 20 ml of carrier oil. Several of the inexpensive forms of rosemary are recreational but do not have the therapeutic benefits found in some of the other more potent forms. These forms may not be specified on the bottles of oil.

You may try rubbing the solution into the scalp for two minutes each day and then a warm towel or other covering is applied on top for 10-20 minutes. The scalp is not washed for at least four hours after.

--See also section 6 under Other Problems: Changes in Skin Pigmentation.

Arthritis
Inflammation of the joint. Osteoarthritis is bony bits in the joint which causes pain and swelling. Rheumatoid arthritis is caused by the immune system attacking the joint.
Atopic dermatitis
An allergic response in the skin that causes itching and subsequent excoriation (see also eczema).
Atrophy (skin)
Thinning of the skin due to diminution in any of its components. With epidermal atrophy the skin looks thin, translucent, and wrinkled like a cigarette paper. Atrophy of the much thicker dermal layer results in a depression. In both cases (epidermal and dermal atrophy) the blood vessels are easily seen through the skin. There are two times a person with alopecia areata may aquire skin atrophy. One is as a side effect of steroids, case in point, "My Dermatologist also suggested that he could inject my eyebrows because people have great success in growing them back that way. I thought, what the heck, it would be great to have eyebrows again. Well, he did it, and instead of brows I got big, deep, wrinkles in my forehead (I looked about 90!). He assured me it would only be temporary (it lasted months)." The other occasion is when you loose your hair. The hair follicle and its appendages undergo an involution the end result of which is a diminution in the width of the scalp, case in point, "I have noticed that my scalp is depressed in the area of the baldness. It has become noticeable to me because the area that is growing back seems to have built up again."
Autoantibody
An antibody directed against normal tissue. Occasionally autoantibodies may be recognized in serum. In some cases the titers of autoantibodies may correlate with disease severity and provide a useful way of monitoring long-term prognosis. In other cases the presence of an autoantibody does not establish a cause effect relationship to the disease. Some other process may have released or altered a given antigen so that autoantibodies are produced secondarily. The presence of autoantibodies by themselves does not necessarily mean that the patient has a disease.
Autoimmune disorder
A disease resulting from a disordered immune reaction in which antibodies attack one's own tissues as in lupus and rheumatoid arthritis.
Autoimmune polyglandular syndrome
Over the past 50 years or so a number of disorders of unknown causation have been classified as autoimmune based on the clustering of various laboratory abnormalities. The diagnostic scheme for autoimmune disorders is based among other things on:
  1. The presence of inflammatory cells (lymphocytes) clustering against a particular component of an organ. Similar to alopecia areata these inflammatory cells consist primarily of CD4 and CD8 lymphocytes.
  2. The presence of organ specific autoantibodies (see dictionary).
  3. The association to HLA genes (see dictionary).

The association of multiple endocrine disorders in the same patient prompted Blizzard, Maclaren and Neufeld to use of the term Autoimmune Polyglandular Syndromes (APS) for these conditions. Their Type I APS may be seen in young adulthood or early childhood and has an equal incidence in both males and females. It is comprised primarily of three primary disorders- Addison's disease, hypoparathyroidism and chronic mucocutaneous candidiasis. The prevalence of these associated disorders has been summarized as follows:

Endocrine disorders
hypoparathyroidism90%
Addison's disease60%
Gonadal failure45%
Autoimmune thyroid disease10%
IDDM (insulin dependent diabetes mellitus)1%
Nonendocrine disorders
mucocutaneous candidiasis75%
malabsorption syndromes25%
ALOPECIA20%
pernicious anemia15%
chronic active hepatitis10%
Sjorgen's syndrome5%

Type II APS is the more common type of polyglandular failure. It is seen at all ages but more commonly in adults. There is a strong female predominance and often there are family members with similar manifestations. The most common endocrine abnormalities in this group include Addison's disease, autoimmune thyroid disease, and IDDM. Common nonendocrine type of manifestations include ALOPECIA, vitiligo and premature greying of the hair. (For more information see WJ Riley Horm Res 38(suppl 2):9-15, 1992.)

The following is a letter writen to me by a patient suffering from this condition:

Hi! I am contacting you after having read your letter about your daughter's hairloss and how it has inspired your research. I am very moved, to say the least. I am a 37 year old woman, living in Los Angeles where I was born. I was exposed to DES (Diethylstilbestrol) in utero and now suffer from multiple autoimmune endocrinopathies. (at least 7 different types). I have had brief periods where I have experienced excessive hair loss, though always with regrowth immediately afterwards... this year I have lost more hair than ever before and i am developing bald spots where no new hair seems to be sprouting. It is a very traumatic thing to have to go through, although I am less concerned about my appearance than I am about my health. I have not been seen by a Doctor (regarding my autoimmunities) since I was "turned loose" from UCLA's medical research center 17 years ago... I was molested by a Doctor during my first year there as a patient/oddity along with having been a "guinea pig" or a living cadaver to be poked and probed with no consideration for the frightened teenager lying naked on the table. Two years ago I took a fall on some steps and broke my wrist. The osteopath who treated me discovered that my bones (after 2 months in the cast) did not seem to be fusing, or were healing at an extremely slow rate. It was then that I discovered that I was in the advanced stages of osteoporosis. I have beeen unable to get any kind of health insurance...am presently on state disability (as I am manic depressive and suffer from severe attacks of panic and anxiety) and when I look ahead to what the future may bring, I see nothing....and it is such a strange thing to live without any hope whatsoever. I am not so much afraid as I am lost. The Doctors at UCLA had placed me on estradiol and provera, which, as I told them, caused me to feel as though a war was taking place within my body. I was experiencing more extreme highs and lows than I'd ever known (which is truly saying something!!) and yet, was told consistantly by one Doctor after another that the replacement hormones "should be making me feel better"...as though I was not cooperating.!! Finally, I just gave up. I took it upon myself to stop taking the hormones as well as the advice and mental abuse I had come to expect from all Doctors. I am not sure what I'm asking for here... I don't know what I want or even that I COULD want for something...I just maybe want to be heard without being told that I am wrong or that it is my fault that I don't respond well to the medicines I've been given. I do have one hope and that is, that by hearing this, perhaps it will contribute somehow, a bit more information, to your research. So...I guess I DO have some hope alive within me, after all...Please feel free to share any of this letter with your daughter, if you feel it would be of any benefit to her. If nothing else, she might understand that she is not alone... If she needs or wants to communicate with me, I would welcome it!

B

Bath oils
A lubricant and anti pruritic product added to your bath in order to relieve dryness. These oils make the bathtub quite slippery, so be careful.
Beta catenin
A few years ago it was noticed that a protein, beta catenin, was associated with cells which were destined to become hair follicle cells in embryonic mice. More recently the group (Elaine Fuchs at U. Chicago) made transgenic mice which expressed a form of the protein which hangs around cells for longer than usual. These mice showed extreme hair growth, sometimes to the extent that benign follicle tumours developed due to excessive stimulation of the cells. Unlike 'natural' growth, the hair grew in all directions. They now are asking whether a topical application of this could be developed, whereby baldness could be treated by creating new follicles. George Cotsarelis is quoted as saying that the work is 'outstanding' but doubts whether any treatment of baldness is feasible this way. However, for us pecians, if current ideas are correct, then new hair follicles are presumably going to be zapped by the immune system just as readily as the old ones.
Biotin
One of the essential water soluble vitamins manufactured in the gut by bacteria. Another chemical called avidin (found in raw egg white) binds to biotin and prevents its absorption. Symptoms of biotin deficiency include lack of appetite, nausea, vomiting, and depression. In experimental animals biotin deficiency has caused an eczematous dermatitis and loss of hair around the eyes (the so-called "spectacle" eyes). Some people recommend taking biotin for nail problems (See Nail Changes in section 6). Remember that biotin is water soluble. What this means is that if you take more than your body needs it will be excreted by the kidneys, through the urine. The reccomended daily allowance of biotin is 300mg.
Bleach
A chemical used for the alteration of hair color. It usually contains hydrogen peroxide/ammonia mixtures.
Bonding
This is a type of non-surgical hair replacement that uses a horseshoe-like track of existing hair about 1/4 inch wide is shaved to about 1/8 of an inch long. The hair is shaved close to the head approximately 1/32" in length. The bonding glue is then applied to the hairpiece which is attached to the hair, NEVER ON THE SCALP! The bonding method is to be used on people who have hair to bond to. You do not want to bond directly to the scalp. Bonding lasts approximately 6 weeks, as the hair grows the hairpiece slips around and must be tightened. Removal is with solvent (sometimes baby oil and alcohol) or it can be cut off.

Male pattern baldness is where the bonding method works best. Those of us with AU and AT should never bond hair as we do not have the hair to which the bonding glue can be applied. I do not suggest that it be used for AA for two reasons. First, the fall out pattern of AA is unpredictalbe and the bonded hair may be gone tomorrow. Second, the existing hair is in such a fragile state and putting excess stress can excelerate the loss.

In some cases the bonding method of hair replacement can be used for women with androgenetic hairloss. My only caution with this method is the excess stress it places on the existing hair. It is important with thinning hair that the attachment (bonding, clips, tape) be rotated to give the existing hair a rest. Continued use of attachments will cause traction hairloss.

Boric acid
Boric acid and sodium borate are potentially toxic to people and pets. Exposure to boric acid (e.g., after a mouthwash) has caused diffuse alopecia. If taken with suicidal intent, it may cause total alopecia after ten days. Serious poisonings in humans have rarely been reported following a single acute ingestion. Toxicity is more likely with repeated exposure to raw or abraded skin or from repeated ingestions.
Braiding
Braiding is another attachment method used sometimes used for AA. This is when the existing hair is braided in long rows and hair extensions are sewn to the rows. This method pulls on the already fragile hair and causes it to come out even faster.
Broader spectrum of alopecia areata symptomatology
A compendium of most studies on the genetics of alopecia areata will indicate on average that approximately 20% of patients have an affected relative with the same diagnosis. Furthermore, these studies indicate that the severity of the condition in the proband in no way predicts the amount of involvement in any other affected member. Although there are several groups around the world collecting families with AA/AT/AU for use in genome screen, it is my personal belief that their experimental designs are flawed and will lack power to show genetic linkage. Additional power could be added to the studies if phenotypic manifestations (phenotype= symptoms expressed in a genetic condition) of the genetic liability to alopecia areata could be documented. Let me explain- There are many studies and patient testimonials indicating that patients with alopecia areata do suffer a selective vulnerability to allergic disorders, e.g., hay fever, asthma, eczema. Although these allergic disorders are very commonly seen in the general population (approximately 15%), their incidence in patients with alopecia areata is more than double (approximately 40%). I would argue, or theorize, that these atopic disorders are similarly expressed in the parents, siblings and relatives of patients with alopecia areata. These characteristics although milder and falling short of expressing hair loss, comprise what I would call the "broader spectrum of alopecia areata symptomatology" (BSAAS). In essence I would postulate that hair loss in patients with alopecia areata represents the tail of the distribution of a whole host of symptoms. My point is that studies limiting the phenotype of classical allopecia areata to hair loss may not be the most accurate way of finding the gene(s) for alopecia areata.

There is an interesting article by Matthysse et al. (J Psychiat Res 26(4):461-473) written from the mental health perspective that recommends various "bootstrapping" techniques to "turn non-Mendelian into Mendelian phenotypes." One of the techniques (detailed in Matthyse and Parnas J Psychiat Res 26(4):329-44) is to expand the phenotype in order to increase the number of persons with the condition. The assumption is that a "minor" gene for the disorder may be a "major" gene for something else, eg, a minor gene for eczema may be major gene for alopecia areata.- I do believe that the most parsimonius model for alopecia areata is one where several genes interact with one another to produce the BSAAS.

One way to offer suggestive evidence for this was of thinking is to make a survey among our participants and divide them into 2 groups. One group would have only one person affected and the other group would have at least two persons (brothers/sisters/brother-sister/children) affected. Finding a higher prevalence of atopic disorders in the parents of those families having two siblings affected would suggest that the broader phenotype is a manifestation of the same genetic liability.

Bronchial asthma (asthma)
A disorder of the lungs characterized by wheezing, difficulty in expiration, coughing and a feeling of constriction in the chest.

C

Cadaverized hairs (Cheveux cadaverisees)
Small plugs of degenerated hairs in the follicle opening. Their presence suggest a rapidly spreading foci of alopecia areata.
Callousness
A physician who advises the parents of a young boy with Down syndrome that their son will never be aware of his appearance or hair loss because he is mongoloid.
Candida
Candidia albicans is a yeast like fungus that inhabits the body and can get into the blood stream, and sometimes gets out of balance and takes over. Candidiasis can effect various parts of the body most common being the ears, nose, gastrointestinal tract, and bowels. Other areas or symtpoms known to occur with Cnadida overgrowth are muscle and joint pain,sore throat, congestion nagging cough, numb hands, legs, or face, tingling sensation, vaginitis, kidney and bladder infections, arthritis, depression, hyperactivity, hypothyroidism, oral thrush, athlete's foot, ringworm, and jock itch.

Changing our diet can lower the levels of Candidiasis, by avoiding some foods and adding some supplements like essential fatty acids (flaxseed oil ect) and garlic oil suppresses the Candidiasis growth.

Catagen
The end of the active growing phase of the life cycle of the hair. It is a transitional stage between the growing phase (anagen) and the resting stage (telogen). In catagen all growth ceases and the "club" hairs are formed.
CD4/CD8 ratio
The regulation of the cellular branch of the immune system called "T-cells" are usually expressed in terms of help and suppression. CD4 (helper) cells refer to a special type of T-cell lymphocyte that recognizes foreign substances, helps mount an antibody reaction against the same and helps recruit other cells to ward of the invader. CD8 cells, on the other hand, try to suppress the immune response.

The CD4/CD8 ratio is widely used in clinical practice although the values themselves have to be standardized for each laboratory. A low number may signify that your CD4 lymphocytes are low (as in AIDS) or contrariwise that the CD8 cells are in overabundance (e.g., an infection with EBV, hepatitis B virus, or even cytomegalovirus). There are at least a dozen or so publications on the subject of CD4/CD8 ratio in alopecia areata. The results have been somewhat variable. One possible explanation is that some studies compared apples and oranges including in their analysis active patients along with those in remission. Our own study showed that in patients with active alopecia areata (proven by biopsy) this ratio is increased. Other studies have led me to believe that it is due to the combination of both an absolute increase in the number of CD4 cells and a diminution in the CD8 cells.

Celiac disease
It's an intestinal disorder caused by a wheat/gluten allergy. Celiac disease has a prevalence of 1:200 in Europe. Gluten itself is the proteins (primarily gliadins and glutenins) left behind after starch is washed away from wheat flour dough. Symptoms are diarrhea, bloating and general stomach discomfort after eating wheat -- can be severe or mild. Atypical symptoms include anemia, short stature, growth retardation, and alopecia. There is also a "silent" form of celiac disease wherre the patient is positive for antibodies (see below) but has a normal intestinal biopsy. This group develops celiac disease later in life. The disease manifests itself when the intestine's villi lay down flat and stop absorbing nutrients. Many problems follow due to malnutrition.

In the April 3, 1996 Journal of the American Medical Assn a study appeared that associates alopecia areata and celiac disease (see also: Celiac disease and alopecia areata: Report of a new association", Corazza G, et al. _Gastroenterology_, 1995, vol. 109, 1333-1337). The treatment for celiac is a wheat-free, gluten-free diet. This was tried on a fourteen year old boy with aa, and it resulted in full regrowth of head and body hair. The study showed that three patients who were asymptomatic for intestinal disease but had aa tested positive for celiac disease. The study suggests that aa may be the only clinical manifestation of the disease and recommends that antigliadin and antiendomysial antibodies should be included in the work-up of patients with AA.

Apparently many people are allergic to glutenous products. This is probably due to the fact that we tend to overuse gluten in our American diet. Gluten includes wheat, oats, barley and rye. Gluten is the component in these products that makes them sticky, allowing them to be kneaded into breads. Alternatives to these grains include amaranth, quinoa, millet, buckwheat, rice and corn. Also, teff, spelt and kamut have low levels of gluten and may be tolerated by some. Although wheat and gluten are tough to avoid in processed foods and in restaurants, it's not that difficult to avoid with fresh foods you make yourself.

Avoid:

  • Malt (in any form) syrup, flavoring etc.
  • Malto-Dextrins -- this food additive is either made from barley malt or acorn flour. It should be avoided if the source is unknown.
  • Colorings and Dyes from lakes expecially red and yellow
  • Hydrolyzed Vegetable Protein (HVP) Hydrolyzed Plant Protein (HPP) and Textured Vegetable Protein (TVP)
  • Monosodium Glutamate
  • Emulsifiers
  • Lectins/Lecithins (some celiacs react to these)
  • Canola Oil (some celiacs react to this)
  • modified food starch -- can be made from wheat or acceptable ingredients such as corn arrowroot potato tapioca or maize. This is one of those if you don't know don't eat it kinds of foods.
  • gluten peptides
  • hordeins of Oats and Barley
  • Distilled white vinegar (if distilled in grain) and malt vinegar
  • ethanols/extracts proteins from grains can be carried over into alcohols and extracts such as vanilla during processing.
  • Wheat, barley rye, oats, spelt, semolina, kamut, triticale, quinoa, millet, buckwheat, amaranth, tef
  • Fat replacers including Olestra, Otrim,Replace
  • Natural Flavor --can contain gluten-containing grains

Lots of good stuff you can still eat: vegies, fruit, dairy products, rice cakes. Of course, the more other things you don't eat (like dairy products, meat, sugar, etc), the harder it is. You can eat dairy products, but not red meat. Not eating pasta is the hardest -- but there is pasta made from vegies (like Jerusalem artichoke hearts) in health food stores. It is certainly true that you have to read the labels because "soy protein" which can contain wheat seems to be in everything, also caramel and malt flavoring. Some ice cream even contains the stuff. Because so many people are allergic to gluten, there are a wide variety of products available ("wheat-free" or "gluten-free") that can be found at health food stores. A catalog containing wheat-free and gluten-free bread mixes and related things is produced by Wilde Temptings (1-800-434-4846). Bette Hagman has great "gluten free gourmet" cookbooks which have recipes for gluten free deserts and breads you can make in a bread machine. Remember that there are flour replacements such as rice flour, potato starch flour, tapiocca flour and more. You don't have to do without good food.If you would like to know more about celiac disease a good web site to visit is www.celiac.com.

CGRP
Theodore J. Daly of Garden City Dermatology, New York has recently had an article published in the Archives of Dermatology. This article has been publicized by several news networks (July 1998).

Dr Daly's research has focused on examining the blood plasma levels of the vasodilator/immunomodulator CGRP (Calcitonin Gene-Related Peptide) in people with alopecia areata. He took serum samples from 18 people with alopecia areata and 69 control samples from people without alopecia areata. The serum samples were analysed using a technique called "radial immunodiffusion" (RIA). This is a simple technique to define concentrations of biological substances in solution. Dr Daly found that in people with alopecia areata the concentration of CGRP in the plasma was about half (53%) that of control samples.

Dr Daly suggests that this apparent lack of CGRP could have an important influence on alopecia areata development. He believes that without the vasodilatory properties of CGRP there may be a reduced blood flow to hair follicles and this may result in dystrophic hair follicles less able, or unable, to produce hair fiber. In his own words (from a post to our list server): "AA may be autoimmune in nature, but I believe that CGRP, a potent vasodilator and immunomodulator, is first decreased in patients with AA. We have shown lower serum levels and other researchers have shown lower tissue levels. The low CGRP causes the hair to grow poorly due to decreased blood supply and allows the immune aspects of the hair to be exposed due to lowered immune protection by CGRP. I call this the 2 steptheory-1)low CGRP 2) immune response. I believe both aspects must be corrected to have hair regrowth." He also suggests that lack of blood flow may also account for nail pitting, eczema, and pigmentary abnormalities.

CGRP also has immunomodulatory properties and apparently suppresses antigen presentation to lymphocytes and slows down their proliferation and reactivity. This suggests that people with a deficiency of CGRP may have a greater susceptibility to inflammatory reactions as occur in alopecia areata. Calcium, nicotine, caffeine as well as steroids and pregnancy increase CGRP levels

Dr Daly believes that this deficiency in CGRP shows that people develop alopecia areata as a result of deficient thyroid production and that the autoimmune hypothesis of alopecia areata development needs to be modified or may be entirely wrong. He believes that using treatments directed at replacing and/or increasing levels of CGRP in the blood stream of people with AA may be an effective promotor of hair regrowth.

Some comments would be:

  1. Eighteen samples is a very small number to draw sweeping conclusions from. We had a previous "break through" a few years ago with the announcement by one research group that they had found cytomegalovirus in alopecia areata affected hair follicles in a small study. This study was repeated by other scientists (using many more alopecia areata affected volunteers) who were unable to obtain similar results.
  2. Which comes first, the alopecia areata or the reduced CGRP levels? CGRP concentration may change as a result of the systemic activity of inflammatory hair loss. So the lack of CGRP may simply be a consequence of alopecia areata and not a cause.
  3. Lack of CGRP does not suggest why just hair follicles should be attacked. CGRP is universally available (or not as the case may be) throughout the body. Why aren't other organs attacked in people with alopecia areata if CGRP is a trigger for inflammatory reactions?
  4. Over 50 years ago vasoconstriction/blood flow in alopecia areata affected hair follicles was shown not to be significantly different from that seen in normal hair follicles. There is no reliable evidence that vasoconstriction is what causes hair loss. If it was then that would suggest that vasodilators such as minoxidil would be much more successful than they apparently are in treating AA. There are many vasodilatory drugs that have no apparent effect on hair growth in androgenetic alopecia or alopecia areata.
  5. His treatment which may have potential even if CGRP is not fundamentally involved in alopecia areata development. If CGRP does have immunosuppressive effects then it may be useful regardless of the native CGRP concentrations in people with alopecia areata.

References for CGRP in AA include:

Chemotherapy
Literally - any therapy done with chemicals. It had come to be thought of as drug therapy for cancer only, although taking penicillin for that lung infection is also chemotherapy.
Chinese medicine (accupuncture)
There have been several recorded medical treatments for alopecia in the traditional Chinese medical literature where the condition is known as YOU FENG (greasy wind). It was claimed to be caused by blood deficiency, wind, and dryness due to insufficient kidney Yin. The Orthodox Manual of Wai Ke states, "You Feng is due to blood deficiency which results in failure to nourish the skin by the ascending Qi". Systemic herbal treatment is directed at replenishing the blood, dispeling the wind and strengthening the kidney. Some accupuncturist claim that hair is a by-product of blood. Suposedly, when you are stressed or pregnant less blood goes to your scalp thus preventing the growth of hair. Many of these claims remain unproven by modern scientific studies.

The herbs used in the systemic treatment are usually complemented by drinking lots of water. Systemic treatment consists of mixing equal portions of Rhizoma seu Radix Noptergii, Fructus Chaenomelis lagenariae, Rhizoma Gastrodiae, Radix Paeoniae albae, Radix Angelicae sinensis, Semen Cuscutae, Radix Rehmanniae conquitae, Radix Ligustici walchii, and grinding them into powder. The powder is mixed with honey to make pills the size of a "Chinese parasol tree seed". The pills are taken 4 to 6 twice or thrice per day for about 6 months. The alopecia pills and information of the same can be obtained through the Net at chiherbs@primenet.com. The pills are fairly inexpensive $2.75 a bottle (100 per bottle). That is about $15 per month. Stores may sell a similar preparation under the name of Shen Min Hair Nutrient. You may also want to review the definition of Trichogen elsewhere in this Dictionary.

The accupuncture practiced by Chinese medical professionals involves several different steps. First, the practitioner applies a lotion to the scalp. The lotion contains herbs (mostly ginger but Westeners use cedar, sesame, olive or eucalyptus oils) in ethyl alcohol. Ginger contains phenol, a chemical compound previously used in the treatment of alopecia areata. Phenol acts as an irritant and may increase blood flow to an area. These are massaged directly into into the scalp where hairloss is occurring once or twice daily.

Next, the practitioner use a tooth pick or needle to poke on the AA patch without piercing the skin. Traditional accupuncture uses a "7 star needles" that looks like a hammer with 7 needle but has a flexible handle. This instrument is also called a Chinese dermal hammer (a small hammerlike device, usually made of lightweight plastic or metal which has one end a simulated hammer about a half inch in diameter with many fine protruding needles (OUCH). This instrument has also been used in other dermatological conditions including psoriasis, eczema, certain rashes and wrinkles.

The scalp is tapped slightly with the 7 needles especially around the edges of the lesions. The poking effect may, again, be similar to other irritants been used on AA. It is used to "awaken the nerves" and improve blood flows. Lastly, the practitioner presses his thumb hard on the AA patch and rocks his thumb for a few minutes without pulling out any hair. This, again is again done to improve the blood circulation. Overall, visits should cost between $10 and $30. Anybody trying to slap a $50 tab on you each time are way over priced. Treatment may last anywhere from a few weeks to a few months depending on the severity of the condition.

There is an interesting article detailing the use of traditional Chinese herbal therapy in atopic dermatitis. As you are already aware AA and atopic dermatitis are often seen coexisting in the same patient. The study reported clinical improvement of the condition but pointed out that given the number of herbs and different active ingredients it was difficult to discern a mechanism. The authors also found that their concoction was potentially toxic and could produce liver damage. (Sheehan M, et al, Efficacy of traditional Chinese herbal therapy in adult atopic dermatitis. Lancet 1992, 340:13-17).

Another use of Chinese herbal therapy is in restoring hair pigmentation (e.g., premature graying). The use of He Shou Wou supposedly nourishes liver and kidney essence thus making the hair darker. The name of the herb comes from an ancient story of a famous military leader who was condemned to death by confinement in a remote cell without any food or drink. He was able to survive by consuming the leaves and roots of an accesible vine-like weed (polygonum multiflorum). After one year his keepers went back to collect his remain only to find him completely rejuvenated with lustrous black hair. Since that time the herb has been named in his honor (He Shou Wou). The herb may be found as an ingredient in a patented formula called "Shou Wou Chih" or Fo Ti. Another remedy for restoring hair color is black sesame seeds (one tablespoon daily). The seeds are roasted and ground with salt to make a condiment or mixed with honey or powdered sugar for a sweet version. See the article Integrating the Traditional Chinese Understanding of the Kidneys into Western Herbalism by for more information (especially section 8).

Note: The terminology of Chinese herbal remedies may be somewhat confusing. Fo Ti, Shou Wu, He Shou Wu, Radix multiflora polysomething or other... are all the same. Trichogen and Shen Min contain Shou Wu (amongst other ingredients.)

Chlorine
Poorly controlled chlorination or bromination of swimming and spa pools may produce skin irritation. This may be accentuated in a person who already has dry skin/eczema, i.e., many people with alopecia areata. Also, lime, magnesium and iron from hard water that are deposited in skin fissures may produce mechanical irritation.

Fitzgerald DA, et al. (1995) Spa pool dermatitis. Contact Dermatitis 33:53.

See also section 6: How do I take care of my skin?

Cimetidine (Tagamet)
An anti-histamine used primarily to inhibit gastric secretions in people with ulcers. It has been used as an adjunct in the treatment of alopecia areata for those patients that have developed tolerance to the effect of topical irritants, e.g., SADBE. The results of this approach have been mixed. Cimitedine also has antiandrogenic properties and has been used for androgenetic alopecia. At higher doses, the antiandrogenic effects may lead to enlarged breasts or sexual problems. Paradoxially there have been sporadic anecdotal reports of cimetidine itself causing hair loss. Headaches, dizziness and mild diarrhea are potential side effects. Older people and those who are very ill may experience depression, mental confusion or disorientation. Tagamet may also affects the liver enzymes.
Clinical trials
Clinical trials are the way of testing drug safety, efficacy, and pharmacology. Thus far many of the clinical trials on alopecia lack originality and recapitulate failed ideas of previous decades. My feelings on this subject are exemplified in a short play entitled "Darwinism and Clinical Trials on Alopecia."

I am sitting at the breakfast table reading my newspaper when a picture on the first page draws my attention. A young distinguished scientist was caught performing fraudulent clinical trials and is being sent to prison. Fifteen years in jail and 15 year probation has been the harsh sentence. A plea bargain has allowed him to retain some personal possessions otherwise disputed under the Ricco statues.

I raise my eyebrows. Uhhmmmff.

A hazelnut aroma suffocates me. I pause to sip discretely the coffee that my wife has placed in front of me.

"The details of this remarkable schme have been found within the archives of the FDA", quotes the newspaper.

I wipe my lips with a handkership that had been tucked in between my wallet and my pocket.

"The FDA is an ancient organization originally derived from the Fumbling Dictographers Association. It was a group of federal employees that because of their tenure could not be fired but, rather, were clustered together and isolated from otherwise better employees. The incept was based on the dictum, "if you can't fire them, give them good recommendation so that they can move to another job."

The organization was charged by President James Garfield with the responsibility of copying a series of Spanish transcripts that dealt with the history of malaria. Unfortunately the President was assasinated before seeing the end result of his mandate. Unable to read or speak Spanish, the FDA labored at copying over and over the original text and misattributing its authorship. The recreated text gave rise to Gorjas manuscript on malaria. By means of a singular series of mistakes the text was transformed to an epistolary narrative on polio. Eventually, accumulated errors gave rise to the use of steroids in alopecia. Sensitizers and irritant were different interpretations for a term the FDA had originally translated as skin tenderizer."

I sit, amazed by the newspaper account. No wonder I always confused DPCP with DNCB. SABDE was just more gibberish.

I felt sorry for the investigator that was sent to jail. The FDA in mistranslating the original text may have inadvertently attributed authorship to the wrong person.

I signal my wife with my hand to call her attention. "You see Gisela," I said imperturbably, "Although there are many clinical trials in alopecia they are all rehashed versions of one that never even attempted to find a cure for the condition."

Teaching point: Wouldn't it be nice if the cure for alopecia is found from experiments designed to treat or cure alopecia rather than high blood pressure, prostate dysfunction, glaucoma, organ rejection, etc?

Cloche hat
A cloche hat fits close to the head and has no brim. Think of a 1920's Betty Boop "flapper" look. It's different than a "kettle" hat which generally has a larger look and is a different shape. Cloches mirror the shape of the head.
Comb
Be carefull when selecting or using a comb for your hair. Hair is easily elongated and fractured when wet. Use your fingers and dry your hair before detangling with a comb. When buying combs and brushes select them with widely spaced teeth or bristles so they are better able to glide through your hair. Those styles having rounded tips are best for fragile hair. These qualities (wide spaces and rounded tips) in a comb or brush are far more important than whether they are made of synthetic or natural materials.

The following is an excerpt, loosely translated, from a TV news broadcast in Turkey:

“A catastrophic event would nearly happen in Bulgaria when the Head of the Balds' Association was caught with a COMB in his pocket. The man was going to be removed from the Association as it was forbidden to carry a comb according to the rules of their association. The man could only convince the members not to remove him by saying that he was carrying the comb for his moustache!”

Complement system
The complement system primarily gets activated when antibodies react with their antigen. This is a primitive system of defense that leads to the elimination of the offending agent, e.g., if the antigen-antibody are located in the surface of a bacteria, the complement system results in the lysis (makes them burts) of that foreign invader. The usual mechanism by which they cause death is by either phagocytosis, attracting neurophils (a type of white blood cell) or promoting an inflammatory response. Thus far, scalp biopsy studies of patients with AA have shown a lymphocytic infiltrate around the base of affected follicles, neutrophils are largely absent, there is no apparent cell necrosis (the cells in the hair follicles remain dormant not dead), and evidence for an antibody mediated reaction is scant or contradictory. I don't believe that the complement system is a primary player in the pathophysiology of AA.
Complete Blood Cell Count (CBC)
The enumeration of the various elements of the blood, i.e., red cells, white cells, and platelets. Manual methods have been supplanted by automated techniques which provide both the total numbers for exact type of cell as well as their morphological indices. The CBC is usually reported with the hemoglobin and hematocrit.
Compliment
They are "halos" of human hair which sit on the head. These compliments weigh a little over an ounce each. They simply sit on your head, encircling it like a wreath. You can wear several of them at a time. They are of primary use for females with androgenetic alopecia who have enough hair to hide the string they are hung on. You can obtain more information on hair compliments from Maria Posa at Hair Compliments in Strongsville, Ohio at (216)238-9779. You can order them by phone if you have already measured the circumference of your head. If you have almost no hair you would probably need three halos- but the more the merrier for a thick lush look. If you have absolutely no hair, you would put a hat on top of your head with the compliments. Each halo is made from European human hair and cost about $150. If you buy two, Maria usually throws in a third one for free. They may be died to any color you want.
Compresses
A wet dressing soaked in cool tap water and applied to affected skin. sometimes aluminum acetate, saline, or potassium premanganate are mixed with the water. The compresses are applied for a period of some 10 to 15 minutes and changed every 5 minutes to ensure their wetness. Compresses have been used primarily as anti-pruritic, anti-inflammatory, and cooling. They are particularly effective in eczematous conditions.
Conjunctivitis (Allergic)
Some people with asthma, eczema or hay fever also suffer from allergic eye conditions. These allergic eye conditions usually become apparent before the age of 30 years. Characteristic symptoms include itching, sensitivity to light, and inflammation of the eyelids. Symptoms may worsen when exposed to ocular irritants such as smoke and to certain foods or food additives. Treatmen consists of avoiding any offending allergens and systemic antihistamines. Topical antihistamins are used in conjunction with vasoconstrictors to reduce the redness in the eyes but prolongued use of these preparations may by itself induce a type of contact conjunctivitis.
Connective tissue
The group of cells that together provide the support elements of organs.It is primarily the extracellular matrix that provides a given organ its 3D shape. Many decades ago they were considered passive in nature but now research has shown that they play an active role in organizing the cellular architecture of organs, exchanging signals, etc.. Since collagen is the most abundant protein within connective tissue, these conditions were also known as "collagen disorders". This was obviously a misnomer since connective tissue also has elastin, glycoproteins, etc.. At present the term collagen disorders is restricted to inherited conditions shown to affect the synthesis or expression of collagen. Among the collagen disorders we now find Ehlers-Danlos syndrome and osteogenesis imperfecta. Rheumatological conditions are most prominent in the acquired connective tisue disorders. Systemic lupus erythematosus (SLE), Sjogren's syndrome, rheumatic fever, ankylosis spondylitis, progressive systemic sclerosis, polymiosistis, dermatomyosistis, amyloidosis, rheumatoid arthritis are among the common connective tissue disorders. Many of the aforementioned connective tissue disorders are of autoimmune origin and may be seen in conjunction with alopecia areata, totalis and universalis. The fact that they are not benign/innocuous is what prompted me to do research regarding my daughter's condition. I cannot quote epidemiological data showing the incidence or prevalence of these conditions in patients with alopecia areata and similarly I cannot predict who will or will not develop the condition.
Contact dermatitis
A reaction in the skin due to contact with a material such as metal, etc. Virtually any chemical has the potential to cause an allergic contact dermatitis. Among the most common offenders are nickel (jean studs, bra clips), rubber compounds (shoes, gloves), Balsam of Peru (perfumes), wool alcohols (lanolin), and poison ivy/oak. Although most erruptions develop 24-48 hours after contact, others take up to 7 days for their manifestation.
Copper
Nutritional deficiencies of this element (as in some inherited metabolic conditions) result in loss of hair color and malformed kinky hair.
Cooties (koo' tees)
Cooties are supposed to be little tiny bugs (lice and nits), often imaginary, that live on hair shafts. When I was little (waaaaay back when), we used to make these little paper things in class that were cootie catchers. Depending on which way you opened them, the inside was either white or speckled with little black dots. One approached a friend's hair with the white side out and then turned it so that it appeared to be filled with little "cooties." What fun we had in 4th grade! Be warned however that cooties ain't cuties. Scientifically speaking the method of transmission is through contact with an undesired person (ie, social outcast, a girl if you are a boy, a boy if you are a girl, sibling, etc.). Cooties are just one of the things that make my life miserable. It is because of cooties, that my children can not sit near each other. They may not breathe on each other.... and according to my kids, if they look at each other, they will get cooties!! And heaven forbid if one of 'em touches something of the others. OH NO!! Cootie alert!!

Well there is one advantage of not having hair; you can't get the cooties. Otherwise if you have them, treatment is easily instituted through the use of lindane (Kwell) or "synergized pyrethrins" such as R.I.D. An alternate therapy may be a very painful innoculation. Sometimes a shoulder punch will work, but the proven method is a good hard pinch. Corticosteroid injections, as always, exacerbate the condition. Is there a point in being weird about things that don't exist? Well, maybe just in having fun. (Hopefully this dictionary and its definitions are cootie free!)

Corticosteroid
A drug (steroid) used clinically to suppress inflammation of the tissues.
Corticosteroid "Addiction"
A recent article written by K Wells and RT Brodell and entitled, "Topical Corticosteroid "Addiction" (Postgraduate Medicine 93:225-230, 1993) raises some concerns for people using topical steroids. The article details several cases where the use of potent corticosteroids in areas of high absorption (e.g., face/eyebrows for patients with alopecia areata) lead to acne and streak-like dilatations of the small blood vessels (called telangiectasias). The symptoms were controlled with renewed corticosteroids but flared up every time they were withdrawn. Each time the flare ups came with renewed vigor. In the end it became apparent that corticosteroid, although arresting momentarily the symptoms, made the condition worse over the long run. The authors suggest avoiding the use of long term prescriptions of corticosteroids and avoiding the use of very powerful agents in these susceptible areas. They suggest that psychological support may be necessary in order for the patient to break their "addiction" to topical corticosteroids.

The whole point of the article is that fairly innocous application of steroids may be absorbed even when they are not injected. I have heard that a clove of garlic under the foot inside your shoe will soon start to smell on your breath. I haven't tried it myslef but if this were the case it would attest to the absorbance capacity of the skin.

The article by Wells and Brodell suggest a similarity between the flare ups of the conditions treated by topical steroids and alopecia areata. It is apparent that after repeated aplications, the steroid controlled the immediate manifestation, but ended by making the underlying condition worse in the long run. An interesting point (as basic as it sounds) is that at present we don't have a study comparing the long term outcome (20 years down the road) of patients treated with steroids vs. those that didn' receive them. Who knows maybe the majority of our participants never recovered because of the aggresive treatment they may have received early in life? Maybe those that didn't receive medication have recovered and therefore are not within our list server. These are emphatically a concatenation of loose ideas but may serve as food for thought.

Couvre
The name Couvre I believe is the French term for cover. Couvre is a colored cream used as a waterproof cosmetic to fill in the bald spots on the scalp. It temporarily (until wash out) covers the light shiny scalp and blends in with the hair color therefore giving the appearance of more hair since there isn't any distinction obvious between scalp and hair. It costs about $20/tube. The 800 telephone number to order is 443-4521 or you can email them at couvre@couvre.com. The company will send you a number of photographs of color of hair for you to match. It is also available through Doctor Leonard's Health Catalog, 1-800-785-0880, for $14.99. Ask for item #56044 and tell them what color your hair is so they send the right color.

Couvre works well and makes the bald patches less conspicuous if you have hair to comb over the bald spots. Presumably the product is safe to use even if you are already putting some kind of topical medication on your spots.It doesn't run, even in the rain, even in the shower, even if you sweat. It needs to be washed off with shampoo or soap. Some people apply it by rubbing it onto the salp with a couple of fingers although it comes with an applicator sponge. Wash your hair, comb it out and then apply the Couvre before blow drying. It is somewhat messy and will stain pillow cases and sheets if you don't wash your hair before bed. Also, if you don't wash your hands with soap after application then it rubs off on whatever you touch.

Some people have also used mehndi tattooing as a way to cover the bald spots. The method only provides for temporary results. You can read more about mehndi in section 5 under Wig Alternatives.

Creams
Creams are emulsions of oil-in-water. In a cream, the oil droplets of natural or semisynthetic glycerides, petroleum products, waxes, sterols, volatile oils, or silicones represent the discontinuous phase and are dispersed in water or a polar liquid as the continuous phase. Oil-in-water creams are completely miscible with the skin oils and absorb water, but they are not necessarily water soluble because of their oil content.
Crepe hair
Woolen strands stained in different colors to imitate a braid of human hair. The strands are pulled from the braid and glued to the scalp with adhesive in order to camouflage small patches of hair loss. The process needs to be repeated after each shampooing or after removing the orignal scalp adhesive with a specially formulated product.
Crohn's disease
A form of inflammatory bowel disease that follows a chronic, unpredictable course. Patients with Crohn's disease experience abdominal cramping, tenderness, diarrhea- joy, joy, joy. While it cause remains unknown, research has suggested genetic, immunologic and psychological factors (sounds familiar, doesn't it?). The condition is well known to have extraintenstinal manifestations but primarily to the joints. The skin has also been involved, at least two case reports have correlated Chron's disease and alopecia areata. Therapy is based on avoiding all products containing gluten. Gluten is found in wheat, rye, oats and barley. People with Chron's disease have to avoid food containing flour, cereal products, hydrolized vegetable protein, malt, and starch. A diagnostic test can be ordered based on the presence of anti-gladian antibodies.

Searching medline I found a recent article which from the title sounds like eliminating gluten does not always result in regrowth of hair:

Bondavalli P; Quadri G; Parodi A; Rebora A. Failure of gluten-free diet in celiac disease-associated alopecia areata [letter]. Acta Dermato-Venereologica, 1998 Jul, 78(4):319.

You may also want to check the following article:

Corazza GR; Andreani ML; Venturo N; Bernardi M; Tosti A; Gasbarrini G. Celiac disease and alopecia areata: report of a new association. Gastroenterology, 1995 Oct, 109(4):1333-7.

Cyanocobalamine
One of the water soluble vitaamins also known as B12. It combines with an intrinsic factor for absorption and is necessary for the maturation of red blood cells. Low levels or absence of the vitamin cause pernicious anemia.
Cyclosporin

“I took cyclosporine pills for 4 months but the result was totaly negative. Now that I haven't taken anything for a year and half I am experiencing regrowth. What kind of crazy contition is this?”

An immunosuppressive agent derived from fermentation of a soil fungi (Tolypocladium inflatum Gams). The drug affects the activity of certain types of immune cells (helper T lymphocytes) without affecting others (suppressor T lymphocytes, B lymphocytes, macrophages, etc.). It has been used extensively in medicine to prevent transplant rejection, less so in psoriasis and rheumathoid arthritis.

Although it has been reported that some severe cases of alopecia areata (including AT and AU) have shown regrowth when treated with the drug, its toxicity prevents widespread usage. Some side effects of the medication include renal failure, hypertension, liver damage, an increased susceptibility to infections, tremors, etc. The concentration of cyclosporin can be increased by drinking grapefruit juice, taking oral contraceptives or calcium channel blockers. As one of our lady participants said you could probably obtain better results with less side effects by putting the hair above her lip (that she bleaches) and the hair between her eyebrows (that she plucks) glued to her forehead.

Cytomegalovirus
This is an infectious agent of the herpes family. It can manifest itself in the presence of normal body immunity or it may capriciously prefer to remain dormant until reactivation. Infections are seen most commonly in the fetus, neonate or immunocompromised host. As the name (megalo) implies the virus is associated with the production of enlarged cells. Transmission usually occurs by contact with blood, but the virus is also present in milk, saliva, feces, and urine. The most common manifestations after the first few weeks of life resemble mononucleosis; fever, muscle pain, fatigue, and sometimes an enlarged spleen. There was a published study using PCR amplificiton claiming a high prevalence of CMV in patients with AA.

The original report by Dr skinner suggested CMV was found in or near hair follicles in people with AA. Dr Skinner tested a small number of skin biopsies and consistently found CMV for biopsies of AA affected skin versus biopsies taken from people with other skin disease. He suggested CMV might be causing inflammation which led to hair loss. There is a seperate report on injection of CMV into mouse skin causing localised inflammatory alopecia around the area of injection.

Three different research groups tried to repeat Dr Skinners findings but failed to identify CMV in hair follicles from their biopsies. I think one group used in situ hybridization techniques and the others examined for DNA derived from CMV. It is thought that Dr Skinner was either just "lucky" in finding CMV in all of his samples or he had a problem with CMV DNA contamination in his laboratory.

D

DEBR rat
An animal model for alopecia areata sustained (but not commecially available) by the University of Dundee. Skin biopsies of affected regions in these animals show the same T-lymphocytic perifollicular infiltrates as patients with alopecia areata. There is another less studied animal model for alopecia areata. It is a mice (C3H/HEJ) selectively reared by Jackson Laboratories. As before, this mice model is not commercially available.
dehydroepiandrosterone (DHEA)
DHEA (real name dehydroepiandrosterone) has also enjoyed an enormous amount of publicity out of the rejuvenation fad. DHEA is at a low level early in life, but peaks sharply at about age 21 and then tails off. By age 85, it is down about 95%.

This is a powerful steroid which may provide the precursor for androgen and estrogen in peripheral tissues. There have been many uses for DHEA reported in the medical literature. Among the ever increasing list are its use to restore immune competence in aged animals, prevent atherosclerosis, in aging (restoring some cognitive functions) inhibit platelet aggregability, prevent cancer, and even as an antidepressant. In the layman press DHEA has been said to promote a sense of well being, improve sexual function and grow hair.

I have some concerns based on the fact that the drug has been tested primarily in animals and we don't know its complete range of side effects. I still believe in one of the laws of physics in that for every action there is an equal and opposite reaction. I believe that you can push the body so far with medications (especially a powerful steroid with a plethora of actions) before noticing serious side effects. One possible scenario is the long term risk for cancer for those tissues that actively respond to sex-hormones, e.g., breast and prostate. If you have prostate cancer DHEA could prove deadly.

Of related interest, rom a recent interview in the London Observer of Drs. Malcom Carruthers and Steven Shalet:

“Testosterone controls virility. Low testosterone equals low libido, reduced sexual performance, lack of vigor and energy, and in extreme cases, osteroporosis and bone problems …

“… in light of this, men can blame their urgent need to disappear off to the pub, snooker hall, golf course or rugby international on their hormones, and anyone unhappy with that will be powerless to protest.”

Unfortunately my wife is never convinced about my scientific explanations for playing golf.

Demodex follicularum (mite)
The mite implicated to cause mange in animals has been reported as present in the hair follicle of those individuals loosing their hair. These mites burrow down in the hair follicle.....my goodness, there's a whole lot of shakin' going on in them there follicles!!!

The mites live on sebum, the oily material that the scalp secretes. The mites are universally present in all humans after adolescence suggesting that alopecia may depend, among other things, on the genetic suceptibility of the subject. The following news release relating alopecia to mites was provided to the UPI during a Dermatology conference in Miami, 1998.

Here's the Official Alopeciac Mite Song:

“I love my jeans, and the way they hug, but my genes,
my genes, my genes got bugs,
There's vermin on my chromosomes, and that's why I'm
a chromo-dome,
OOOH, mites!
Get away from me!
OOOH mites,
Let my lashes be!
They are here to stay
and my new shampoo
washes them away,
but they come back too,
and they make me sneeze
and they make me wheeze,
and they make me do the wig strip-tease,
I'm humbled
by their strength and power
they chew on my hair and oil
every day and hour.
I love my genes, and my grandma's, too,
and I want to know - Grandma? Grandma? OOOH,
why didn't mites do this to you?
Can my neighbor get 'em
if I use her pool?
OOOH mites, mites in my genes.”
Dental problems
Jacquet (French chap) around the turn of this century claimed that alopecia areata developed as a result of dental decay. This was at the time when AA was believed to have a "neuropathic" origin where the nervous system in and around the hair follicles was dictating lack of hair growth. Jacquet believed that the destruction of the nerves in the teeth, as a result of decay, was being transmitted through to the nerves in hair follicles and showed up as hair loss.

However, other dermatologists took his idea and showed by statisitics that dental decay in the general population was just as common as in people with AA (bear in mind that tooth decay was much more common at this time).

Hair, nails, teeth and eyes are all related "organs" although their similarity of structure and cell type is much more obvious in less complex animals than ourselves. Although the link between hair and nails being affected is clear, there has been no evidence to suggest that eyes or teeth are affected in AA any more than in the general population. Most likley for mammals (dogs, horses, mice, rats, primates and cattle can get AA too) teeth and eyes are so differentiated from the hair follicles that they escape the attention of the immune system attacking hair follicle antigens - assuming this is an immune based condition.

Depression
Dysthmia is the word to describe a form of chronic, mild , depression . Most people who have Dysthmia are always kind of low. I always describe it to people that there is this line that is signifies a normal level. A dysthimic person is about 20% lower. So when they feel really good they am more like a regular person and when they are down they are way down.
normal========================================
dysthimic================================
major depressive========================

People with dysthimia are not very happy and kind of blue. Most may not even know that there is anything wrong. They never know exactly what is wrong with them, but always feel different from everyone else. They don't feel the same joy in life as other people seem to be getting out of it. Never feel like they are good enough, don't want to be in public or with other people. They sleep alot and just never have any energy, any positive thoughts about their future, and always see the glass "half empty" as they say. They may have a problem with anxiety also and it makes it alot worse. The only way to explain the feeling is like walking around in a fog all the time. One of the participants within our discussion group didn't realize what was her problem until she was 26 years of age. After being put on medication for the first time, she first experienced what it was like to feel "normal" and what life felt like. It was an amazing transformation for her.

You may many things on-line about it, on-line groups such as our alopecia list server that you can join. You just have to do a little searching. List server are like friends that may help you know when you are kicking yourself around.

The hardest part for some persons looking for help has been the fact that other people don't understand what is happening. Most people think that you can just "snap out of it" NOT TRUE!!!!!!!

Dermal papilla
The base of the hair follicle that helps form hair.
Dermal retention
Insertion of synthetic hair fiber into the scalp is a very dangerous procedure and, I'm told, illegal in all states except New Jersey. The synthetic fibers have a barb on one end that are "punched" into the skin. Eventually they fall out unless they are punched deep in to the skin. When punched too deep the synthetic fiber as a foreign object and can elicit an inflammatory response. Scarring and irreversible loss of remaining hair follicles is possible. I have seen a few horror pictures of people after having these synthetic implants -the inflammation and scarring is chronic and extensive. The syntheticimplants had to be surgically removed. No amount of plastic surgery was going to correct the problems of these unfortunate few. Also, the sites of fiber insertion are potential portals for skin infection.

Artifical fiber implants into the scalp were popular in Japan a few years ago until these problems were recognized. The Japanese manufacturers of the synthetic fiber then claimed that they had solved the problem of inflammation by coating the synthetic fibers with a special polymer. However I doubt that this would truely resolve the inflammation problem and it does nothing to block skin infection via the punched holes in the scalp.

New Jersey Files Suit Against United Micro Systems

In response to a lawsuit filed by the New Jersey Attorney General and Division of Consumer Affairs Director, a New Jersey Superior Court judge has frozen the assets of United Micro Systems ("UMS") of Voorhees, New Jersey.

UMS offers a hair replacement system called "Dermal Retention," about which the state alleges UMS made false and misleading claims in both its internet advertisements and in national magazines.

The suit names both former and current owners and employees as defendants. Camden County Superior Court Judge Theodore Z. Davis has ordered the defendants to appear for another hearing on May 18 to respond to the states allegations.

According to the Attorney General, UMS and the defendants "...lured men and women into purchasing their product with unsubstantiated claims about this so called 'hair replacement system' and then turned their backs on the victims when the product failed... We cannot and will not stand by while salespeople allegedly take advantage of trusting consumers. That is why we're taking action in this matter."

Complaints in the case by consumers range include high cost (as high as $8,000), misleading the public by calling the hair replacement "permanent", and that the hair systems did not look natural and came loose within days.

Several UMS employees are also former employees of another New Jersey company called International Cosmetics Laboratories, Inc ("ICL"), which marked a fradulent treatment for baldness called the "cosmetic suture process." ICL was prosecuted by New Jersey Consumer Affairs in 1994 and eventually went bankrupt.

The formal charges against UMS by the state include:

Falsely claiming that Dermal Retention was permanent and that it created "an individual hair effect"; UMS promised that the hair replacement process would look natural and create an undetectable hairline; Misleading before and after photographs were used in its promotional materials. UMS promised consumers that their product was warranteed and had a satisfaction guarantee which were not honored.

Dermatitis
The terms dermatitis and eczema are used interchangeably. Dermatitis can be acute or chronic. Acute dermatitis refers to a rapidly evolving red rash which may be blistered and swollen. Chronic dermatitis refers to a long-standing irritable area. Factors which may result in dermatitis include contact with irritants, allergens, inherited factors, dry skin, injury to the skin, and infection. An important aspect of treatment is to identify the contributing factor and then treat it. Topical steroid creams can be applied to itchy patches for a 5 to 15 day course. Dermatitis is often a long-term problem. If your skin gets dry, moisturize it and be carefull with the amount of soap you use. Consult a dermatologist if symptoms persist for two weeks with no signs of improvement.
Dermatoscope
A hand held lighted magnifier/microscope. Some Dermatologists find it useful in looking for exclamation hairs (see dictionary section), shaft diameter to diagnose andrgenetic alopecia, to evaluate scarring, etc. It is great to be able to see the hairs in their nascent shape and the know how they will grow soon.
DHT
The abbreviation could stand for Dustmites Have Teeth, Dentists Hate Teens, Don't Have Tomatoes, or dihydrotestosterone. Within cells, testosterone is metabolized to DHT by the enzyme 5 alpha reductase. Too much DHT may propititate development of androgenetic alopecia while growth of hair in other parts of the body is accelerated (e.g., extremitites, anterior chest, etc.)
Diet
This is a catch 22 question, should I emphasize proteins in my diet or should I try to avoid the same? Hair is sensitive to protein deficiency causing it to loose its pigmentation and become thin, sparse and easily plucked. Some people attribute this early effect to the body's natural wisdom, namely, trying to conserve protein for more important functions such as heart contractility. On the other hand, a diet too high in proteins may be harmful to your health. Carbohydates and fats can be metabolized to create energy out of them (in terms of high energy phosphate bonds) but proteins can neither be stored (you can't store muscle) or metabolized to obtain a substantial amounts of energy. The oxidation of proteins promotes the formation of free radicals which go on to injure cells. Oxidation and free radicals is the injurious mechanism underlying the inflammatory respone seen at the base of the hair follicle in patients with alopecia areata. It is therefore not surprising that Dr. Andrew Weil, a natural medicine advocate, recommends the following diet for patients with autoimmune conditions:

Eat a low-protein, high-carbohydrate diet. Eliminate milk and milk products, including commercial foods made with milk. Minimize consumption of foods of animal origin. Avoid polyunsaturated vegetable oils of all kinds. Most importantly, supplement the diet with a program of regular aerobic exercise. For more information on diet and other health concern issues you may visit his site at http://www.drweil.com.

Discoveries in medicine
A recent scientific claim that: HAIR LOSS IS CAUSED BY TOOTHBRUSHES. Cleveland: "A toothbrush is a breeding ground for a microbe that attacks the user's follicles, making hair fall out, says Dr. Wilma Berfeld, a dermatologist in Cleveland, Ohio. A follicle is the tiny gland at the root of each hair. The toothbrush-borne microbe causes an infection called folliculitis. For those worried about contracting folliculitis, Dr. Berfeld said the condition could be avoided by buying a new toothbrush every 30 days or sterilizing the old one in detergent in very hot water." After this important scientific contribution most (but not all) of our participants stoppped their obsessive habit of brushing their scalp with a toothbrush. Just to be fair, even seemingly ludicrous scientific assertions have a long track record in medicine. Thus there are previous reports of alopecia areata and homolateral headache due to an impacted superior wisdom tooth (M Romoli and G Cudia: International Journal of Oral and Maxillofacila Surgery 16:477-479, 1987) and another similar article advocating dental therapy for alopecia areta (S Zivkovic: Stomatoloski Glasnik Srbije (a SerboCroatian journal) 37:299-305, 1990).
DMSO
Dimethyl sulfoxide (DMSO) is an inert dipolar aprotic solvent. It is a powerful hydrogen bond acceptor and forms highly ordered structures with water. In all therapeutic forms of DMSO (oral or topical), DMSO is metabolized to DMSO2 (dimethyl sulfoxide) and DMS (dimethyl sulfide). The kidney excretes DMSO2 and it is eliminated in the urine. The lungs excrete DMS, which gives the breath the characteristic garlic-smell (Wood, 1971). Its therapeutic uses are based on its ability to enhance the penetration of biologically active substances when these are applied to living tissue. However, there have been some adverse effects associated with the use of DMSO therapy since the FDA-approved clinical trail began in 1964, including; erythema, pruritus, urticaria, and a slight increase in local skin temperature.
DNCB
DNCB (1-chloro-2,4-dinitrochlorobenzene) is an industrial photochemical and sensitizing agent. A description of its use is missing from the Physician Desk Reference (PDR) manual because it is obtained as a chemical (rather than as a drug). DNCB has been effective primarily in the treatment of warts but its use has fallen into disrepute when it failed the Ames test. Dermatologists with some experience as to its use are divided as to its efficacy. When applied topically, DNCB causes a reaction similar to poison ivy. In some cases the reaction can escalate to that of a severe burn. There are several ongoing trials about the effectiveness of this drug in treating HIV. From Project Inform DNCB Fact Sheet (http://www.projinf.org/fs/dncb.html): "There are no established label or drug indications for the use of DNCB as a medicine, nor are the currently marketed preparations made under established GMP (Good Manufacturing) conditions."
Dystrophy
Inadequate development.

E

Echinacea
A common plant on the praries (Purple Cornflower). The part that is used for hair growth purposes is the woody stem, which is either brewed as tea, or shredded and placed in capsules. I am not sure if in order to extract the tincture they soak the stem in alcohol or another liquid. You can grow it yourself. The plant tends to grow several feet tall. Herbalists suggest that the plan boosts the action of the immune system. They recommend taking E. purpurea (rather than E. angustifolia) 3 capsules per day at luch time (when it seems to work best) or15 drops of the fluid extract. A doctor of natural medicine once told me that in high doses, echinacea can initiate alopecia. Since there are other immune stimulating herbs that do not have as many side effects not many people recommend this treatment.

Echinacea is not recommended for people with autoimmune disorders because it boosts production of interferon-gamma (IFN-g) which is a cytokine (chemical messenger) for the immune system. IFN-g is involved in Th-1 responses, which stands for T-lymphocyte helper cells. Th-1 responses are pro-inflammatory/"attack". Conversely, Th-2 responses (still T-helper cells) are "anti-inflammatory" and order the Th-1 cells to "stop attacking". The same thing holds for melatonin. (See Melatonin)

Ectodermal dysplasia:

“I was born with total alopecia, and my daughter was born with partial alopecia. Aside from alopecia we both have some dental abnormalities. Basically we are missing some teeth, and the teeth that we do have don't have the enamel coating. Both of us also have problems with our fingernails-they are rather unusual as they are thick and curve inward-like an upside down spoon. Our sweat glands and tear ducts don't work the way they should either. A person born with two of the things that I mentioned could be classified as having Ectodermal Dysplasia.”

A recent published study has isolated the gene of a condition that manifests itself with baldness. The condition is called ectodermal dysplasia- a condition described by the English naturalist Darwin over 100 years ago. The disorders arise from disturbances in one or more ectodermal structures and their accessory appendages. The absence of, or deficient function of, at least two derivatives of the ectoderm constitutes a form of ED. Each combination of defects represents another type of ED and has a specific name. At least 150 different forms of Ed have been identified. Individuals affected by ED have at least two or more of the following manifestations:

  • Absent or malfunctioning sweat glands. The patient may suffer from dry skin, hyperthermia, and unexplained high fever as a result of the deficiency of sweat glands.
  • Dental anomalies include missing or underdeveloped teeth.
  • Varying degrees of Alopecia resulting from defective hair follicles.
  • Malformed or missing fingers and toes.
  • Malformed fingernails and toenails, to varying degrees.
  • In addition, patients may have poorly functioning mucous membranes, cleft lip and palate, deficient saliva, hearing or visual defects, inadequate eye fluids and tears.

Familial studies suggested it was a disorder related to the sex (X) chromosome. Some 125,000 Americans suffer from the condition. The results of the study suggest that scientist may develop a screening test to detect women who carry the gene or affected fetuses dring pregnancy- other practical applications (especially as it may relate to baldness remain obscure).

Eczema
A group of conditions characterized by an itching inflammation of the skin. In acute stages it is manifested by reddening, edema and vesiculation. In more chronic stages, eczema there is thickening, scratch marks, and changes in the pigmentation of the skin. Common trigger factors include heat, contact with woollen and nylon clothing, detergents, stress and certain foodstuffs.

Treatment consists of avoiding excessive heating in rooms as this increases skin dryness and itching. Woollen and nylon clothing can (if next to the skin) cause irritation and should be avoided. Clothing made from 100% cotton is ideal. Biological (enzyme) washing powders may aggravate eczema and so should be substituted with non-biological detergents. It should be noted that tiredness and emotional stress do aggravate eczema. Foods implicated in allergic reactions include dairy products, wheat, seafood and peanuts. Dietary exclusion should only be carried out under the supervision of a dietician as this could lead to malnutrition.

Interestingly, there is an increased density of house dust mite allergen (Der p1) in the homes of people with atopic eczema. Does increased exposure to house dust mites cause the eczema or is the increased density secondary to the heavy shedding of skin scales on which the mites feed?

The hypothesis that AE improves if amounts of house dust mite allergen in the home are reduced was the subject of a double-blind controlled trial, the results of which were published in the Lancet (Tan,B.B et al, 1996). Active treatment comprised of Gortex bedcovers, impenetrable to the house dust mite (placebo - cotton covers), benzyl tannate spray, a mite killing agent (placebo - water) and a high-filtration vacuum cleaner (placebo- conventional domestic vacuum cleaner).

Although the severity of eczema decreased in both groups, the active group showed significantly greater improvements and it was concluded that the activity of AE can be greatly reduced by effective house dust mite avoidance.

Emollient
Agents that make the skin soft and pliable by increasing hydration of the stratum corneum. The greater the occlusiveness, the greater the decrease in water loss and resulting increase in hydration of the stratum corneum. Petrolatum is the most occlusive and therefore the best emollient. It is often mixed with more cosmetically acceptable materials to produce a pleasant feeling to the skin.
Epilating
A mechanized way of plucking hairs. Hair should be long in order for it to be trapped by the coils of the machine. Best results (less painful) are obtained when the epilating device is used over flat surfaces (arms, legs) as opposed to curved ones (underarms).
Erythrocyte Sedimentation Rate (ESR)
This tests measures the rate of descent of red cells suspended in plasma. Anything that promotes the aggregation of red cells will increase the rate of sedimentation. The ESR is elevated in those conditions characterized by increases in plasma fibrinogen and gamma globulins. The results tend to be non-specific as a diagnostic tool. An elevated ESR has been reported in hyper- and hypothyroidism, in patients taking birth control pills, during pregnancy, and postoperatively. ESR is used primarily to track disease activity in certain conditions such as lupus and rheumathoid arthritis. The test in not valid when red cells have an abnomral shape (e.g., sickle cell disease), hyperviscocity syndromes, and in severe anemia.
Essential Fatty Acids
Fatty acids that can't be synthesized by the body and therefore are required in the diet are called "essential". Some examples include linoleic acid, arachidonic acid, and linolenic acid A deficiency of essential fatty acids (e.g., after prolonged parenteral alimentation) results in dry skin, eczematous changes, poor wound healing, and sparse hair growth with lightening of hair color. There have been many claims as to their possible benefit in reducing high cholesterol levels, prevention of strokes and heart attacks, angina, high blood pressure, arthritis, multiple sclerosis, psoriasis and eczema, cancer prevention and treatment, allergies, and asthma. (See also, flax seed oil and omega 3-fatty acids). (See also aromatherapy).
Estrogen
"Estrogen" is a catch-all phrase for the three most important estrogens made in the body. Estrone (E1) is produced by the ovaries, and also in body fat/muscles/skin. Estradiol (E2) is produced by the ovaries. Estriol (E3) is biologically the weakest estrogen and is a by-product of estrone metabolism.
  • E1 can convert to E2 and E3.
  • E2 can convert to E1.
  • E3 is a "metabolic endpoint" estrogen.

Estrogen is an indirect antiandrogen - it leads to reduced levels of testosterone. Several studies with topical application of estradiol (estrogen) on men with androgenetic alopecia suggest growth promotion of hair, and/or stabilization of hair loss. The particular study I am thinking of is German:

Orfanos CE, Vogels L. Lokaltherapie der alopecia androgenetica mit 17(alpha) ostradiol. Dermatologica 1980; 161: 124-132.

However, the side effects with estrogen could be significant - for men at least - including decreased libido and, um, growth of breasts plus increased cancer risk.

Looking at AA the story gets more complex as estrogen also has a role to play in the immune system. CD8 T cells (which are destructive cells found in large numbers in/around AA affected hair follicles) have estrogen receptors and are stimulated into action by higher levels of the hormone. Estrogen also promotes proliferation of B cells and production of immunoglobulin. That might suggest estrogen blockers could be of some use in AA assuming these cell types are causing hair loss in AA. However, IMHO estrogen levels are not of fundamental importance in AA (that does not exclude a role for them though) plus, given the side effects of estrogen blockers, their future does not look too bright. Abnormalities in estrogen metabolism, have been reported in other autoimmune disorders, including lupus, rheumathoid arthritis and multiple sclerosis.

Eucaderm
The Eucaderm product is sold by David Satchell. If you decide to buy this product please get it from Mr Satchell as it will prove to be 8 cheaper ($12). Mr Satchell did have alopecia and is very knowledgeable on the subject. I believe he may be trichologist (See trichology in dictionary section). Here is the contact information:
Eucaderm Ltd 7 West Terrace Eastbourne, East Sussex BN214QX England TEL +044 1323645164 e-mail hair@mistral.co.uk

It is apprently great if you have psoriasis or eczema but of all of the list server members that have reported using the product for alopecia, none have reported positive results.

Eucalyptus oil

“Finally, an update on the eucalyptus oil. The oil did indeed help to soothe the stinging and itching of my scalp, but as much as my husband and I both find it to have a pleasant aroma, it was much too overpowering to use in oil form. I have switched to Dr. Bronner's eucalytus soap in diluted form and am using it for shampoo. The shampoo controls the itch quite nicely. The stinging sensation had actually stopped after I first tried the oil and much to my surprise I find that I now have some pigmented hair growing in the areas that were stinging so much.”

Eucalyptus oil (liquid or in a bar) is readily available in health food stores. Very reasonably priced too; affordable for any pocket book. It is used because fleas and ticks are repelled by eucalyptus. (See Journal of Allergies and Clinical Immunology, Oct., 1997) (See Demodex follicularum).

Kiehl's is now making an Eucalyptus Liquid Body Cleanser. As with all Kiehl's products, it's probably not cheap but good quality. You can call Kiehl's at 1-800-KIEHLS-1 for the store closest to you, or a catalogue. It contains the fragrance but not much of the oil per se. Eucalyptus oil is used topicaly never internally.

Exclamation hair
The tapered club hairs that remain in the follicle after the hair shaft breaks. Using scanning electron microscopy the hair fibers falling out from the edge of an expanding bald patch can look very unusual. Frequently, the part of the hair fiber furthest away from the scalp (the oldest part of the hair) looks normal. Closer to the scalp (newer part of the hair) and it can look quite aberrant. We find the shape of the fiber becomes increasingly irregular the closer to the scalp we look. This involves deposits of disorganized keratin and constrictions in the hair fiber. The cuticle can be missing and there can be longitudinal cracks along the length of the hair. Analysis of the hair fiber shows the constituent keratins to remain the same but the way they are assembled to make up the fiber becomes increasingly abnormal.

The irregular construction of the hair gives it weak spots where it can readily break off. This gives rise to the stumpy hair fibers called exclamation mark hairs that can often be seen in expanding patches of AA. This increasing irregularity of the hair fiber reflects the increasing influence of the inflammatory infiltrate through time. Eventually the inflammation builds up to such an intensity that the hair follicle finds it impossible to make any real hair fiber. Breakage usually occurs some 3 to 4 mm from the scalp. Often the broader distal edge tends to be normally pigmented while the proximal edge (adjacent to the scalp) appears paler. Exclamation hairs are not diagnostic for alopecia areata and may be seen in several different conditions including chemotherapy.

Experimental subject's bill of rights

These rights include but are not limited to the subject's right to:

  1. be informed of the nature and purpose of the experiment
  2. be given an explanation of the procedures to be followed in the medical experiment
  3. be given a description of any attendant discomforts and risks that may be expected
  4. be given an explanation of any benefits to the subject reasonably to be expected, if applicable
  5. be given a disclosure of any appropriate alternatives, drugs or devices that might be advantageous to the subject, their relative risks and benefits
  6. be informed of the avenues of medical treatment, if any available to the subject after the experiemnt if complications should arise

  8. be instructed that consent to participate in the medical experiment may be withdrawn at any time and the subject may discontinue participation without prejudice
  9. be given a copy of the signed consent form
  10. be given the opportunity to decide to consent or not to consent to a medical experiment without the intervention of any element of force, fraud, deceit, duress, coercion or undue influence on the subject's decision.

F

Fibroblasts
Fibroblasts are the connective tissue cells of the body. They produce long strands of proteins that act as fibers in tissues. In the skin they produce collagen, reticulin and other elastic fibers. Although the exact role for all of these proteins is not necessarily understood they seem to provide some of the elasticity and leather-like toughness to the skin. At the base of the hair follicle fibroblasts may help to preserve the 3-dimensional conformation of the dermal papilla (the small invagination at the end of the hair bulb). Ultrastructural studies using electron microscopy in biopsies from patients with alopecia areata have also shown irregular profiles and distorted nuclei in fibroblasts. It is therefore one of the cells (among many others) that has been incriminated as pocessing the antigen against which the immunological reaction is directed.
Fibromyalgia

“My hair is just about totally gone, and I have muscle spasms, I can't sleep properly, e.g.; fall asleep about 2-3:00 A.M. and up at 6:00 A.M. for work, this is daily. I am tired all the time, I am very depressed, yet I seem to be moving to fast.”

Fibromylagia referes to chronic and widespread musculoskeletal pain. It is associated with disturbed sleep, anxiety, depression, chronic fatigue syndrome, irritable bowel... (does the list sound familiar or do I need to keep on going?). To top it all, fibromyalgia has been know to antecede hypothyroidism. (See fibromyalgia under Section 6 Other Problems).

Finasteride
A 5-alpha reductase inhibitor that works by reducing the levels of dihidrotestosterone. It has been approved for marketing within the USA for men with androgenetic type of alopecia. Women are warned against using the compound because of its teratogenic effects. I think there is a potential for ambigous genitalia (hermaphroditism). Side-effects of the medication in men include loss of sex drive and impotence.

Finasteride was previously used for prostate conditions at a 5 mg dosage. I haven't read any resuls from long term studies with the drug, the package insert only details results at 24 months follow-up (17% of treated patients had hair loss versus 72% of those in the placebo group). The experimental design for the Finasteride trial differes markedly from that of the monixidil trial making comparison difficult. Thus far there aren't any indications for its use in alopecia areata/universalis.

Flax seed oil
This is a "delicious" oil of deep gold color that can be added to almost any type of food as an important source of omega 3 fatty acids. Different brands may have different tastes. If using it on a salad, mix it with another oil, so you don't get that straight flaxseed taste. It can't be heated over the boiling point of water without its beneficial properties being destroyed. It must therefore be added to food after they are cooked. Flax seed oil is found for sale near the vitamin section of most health food stores in a dark bottle within their refrigerator. It is only good for about 6 months and comes with the date of pressing printed on the side of the bottle. It must be kept refrigerated and should never be left sitting out in the sunlight or exposed to air by leaving the top off- otherwise it can become rancid very easily. If your local health food store doesn't have it, they can order it for you. A good web site for ordering and obtaining some information on the product is www.barleans.com. Omega has a wonderful catalog with all kinds of tips throughout--the phone number is 1-800-661-3529. In the Omega catalog, they give a suggested dose table, which is 1 tsp of oil per day for every 35 lbs of body weight. Another interesting table in their catalog shows which oil to use for whatever temperature of baking, cooking, sauteing, etc. you are doing. The catalog is free and well worth it.

You can also obtain your recommended supplementation of omega 3-fatty acids from the flax seeds themselves. Buy whole flax seeds and keep them refrigerated. Take enough for one week supply, grind them in a coffee grinder or blender, and take two spoons daily.

Omega 3 fatty acids (see dictionary for a definition) are not used as energy by the body as are most oils nor are they stored very much in fat cells. Rather they are used as building blocks for many critical tissues in the body, particularly membranes of the intestinal tract, brain and cardiovascular system. Lack of omega 3 fatty acids causes the body to have to use inferior substances with imperfect molecular structures in an attempt to fill this need and it is little wonder that all sorts of problems can be traced to this.

Flutamide
A chemical that acts as a pure antiandrogen and works by binding to androgen receptors. However, it as no antigonadotrophic effect and the result of binding to central androgen receptors is that it prevents the negative feedback of testosterone and androgen levels increase.
Folliculitis decalvans
This is a rare type of follicular inflammation that leads to cicatricial alopecia. It is characterized by perifollicular pustules, which crust and migrate centrifugally to leave an irregular central area of scarring alopecia with finger-like projections. The disease may be limited to a few patches or extend into a large atrophic bald area. The cause of the disease is still uncertain, but it is possible that a local failure in the immune response or leukocyte function may be the essential abnormality in most cases. Staphylococcus aureas may be grown from the pustules and the abnormal host response goes against these bacteria. Any or all hairy regions may be involved. The scalp alone may be involved or the scalp together with pubes and axillae. There are multiple rounded or oval patches each surrounded by crops of follicular pustules. No other changes may occur, but successive crops of pustules, each followed by destruction of the affected follicles, produce slow extension of the alopecia. Initial therapy during the pustular phase consists of aluminum acetate compresses three times a day, followed by application of mupirocin ointment. To treat the patient, he or she should be investigated for underlying defects of immune response and of leukocyte function as a guide for effective treatment. Systemic antibiotics will often prevent further extension of the disease, but only for as long as they are administered.

Genetic pre-disposition
You're more likely to get *it* than the general population due to your genes (GEE thanks mom!!).

An article in Science (279:720-724, 1998) created some controversy by using an erroneous nomenclature and publicizing having found a gene for alopecia universalis. Although the patients in the article do have universal alopecia, that is hair loss all over their bodies, they do not have "alopecia universalis", a well defined autoimmune condition. The individuals in the article were born without eyebrows or eyelashes. They never experienced any hair regrowth and there was no hair follicle inflammation.

The condition the affected individuals have should have been designated as congenital atrichia. This is a very rare genetic condition that results in abnormal development of hair follicles. It does not involve inflammation of hair follicles as alopecia areata/totalis/unviersalis does. It is probably similar to a condition in mice that have a mutated gene called "hairless". This is not an accepted animal model for alopecia areata or universalis.

Although the genetic research is important in our understanding of how hair follicles are made and grow, it does not have a direct bearing on the inflammato
