Idiopathic CD4+ T lymphocytopenia associated with disseminated flat warts and alopecia areata.
Idiopathic CD4+ T lymphocytopenia is a very rare condition characterized by persistent depletion of circulating CD4+ T lymphocytes, without evidence of HIV or HTLV infection, or other identifiable causes of immunodeficiency. The syndrome can present with dermatological diseases, including viral, fungal and bacterial infections, as well as Kaposi's sarcoma, epithelial cell malignancies, lymphoma and inflammatory dermatoses. We report the case of a 47-year-old woman with idiopathic CD4+ T lymphocytopenia who presented with a 10-year history of disseminated and refractory flat warts from which human papillomavirus type 3 DNA was identified. The patient also had alopecia areata.

Vitamin D3 analogs stimulate hair growth in nude mice.
The active form of vitamin D3 can regulate epidermal keratinization by inducing terminal differentiation; and mice lacking the vitamin D receptor display defects leading to postnatal alopecia. These observations implicate the vitamin D3 pathway in regulation of hair growth. We tested the ability of 1,25 dihydroxyvitamin D3 and its synthetic analogs to stimulate hair growth in biege/nude/xid (BNX) nu/nu (nude) mice exhibiting congenital alopecia. Nude mice were treated with different vitamin D3 analogs at doses that we had previously found to be the highest dose without inducing toxicity (hypercalcemia). The mice were monitored for hair growth and were scored according to a defined scale. Skin samples were taken for histological observation of hair follicles and for extraction of RNA and protein. Vitamin D3 analogs dramatically stimulated the hair growth of nude mice, although parental 1,25 dihydroxyvitamin D3 had no effect. Hair growth occurred in a cyclical pattern, accompanied by formation of normal hair follicles and increased expression of certain keratins (Ha7, Ha8, and Hb3). Vitamin D3 analogs seem to act on keratinocytes to initiate hair follicle cycling and stimulate hair growth in mice that otherwise do not grow hair.

Assessment of hair loss: clinical relevance of hair growth evaluation methods.
This review on hair growth measurement methods focuses on human scalp hair in the context of clinically relevant assessment of hair loss. This phenomenon is the end result of a complex combination of events closely associated with hair cycling followed by defective hair replacement. The methodological spectrum ranges from the most to the least invasive approach. All of the measurement methods referred to are critically reviewed, with their stronger and weaker aspects, in view of their potential application in the skin and hair clinic. The existence of recently developed highly resolutive noninvasive analytical methods capable of exploring almost every aspect of the dynamics of this growth and loss phenomenon allowed calibration of more global scoring method. From this review, the author concludes that a combination of a highly resolutive analytical approach with a global calibrated method seems advisable in the context of the monitoring of hair growth changes for better or worse, i.e. scalp hair growth or hair loss in the hair clinic.

Langerhans cells that express matrix metalloproteinase 9 increase in human dermis during sensitization to diphenylcyclopropenone in patients with alopecia areata.
BACKGROUND: We know little of the initial events during the sensitization phase of contact allergy in humans. Alopecia areata (AA), a disease of unknown pathogenesis characterized by patchy hair loss, may be treated by inducing contact allergy to diphenylcyclopropenone (DPC), later followed by its topical application. OBJECTIVES: To learn more about the initial events during sensitization in human skin, we studied the early events during induction of contact allergy to DPC in patients with AA. METHODS: DPC 2% and sodium lauryl sulphate (SLS) 4% were applied on the backs of eight patients with AA. Punch biopsies were taken 6 and 24 h after application. The biopsies were snap-frozen and cryostat sections were evaluated with immunohistochemistry using antibodies against CD1a, HLA-DR, CD3, CD54 and matrix metalloproteinase 9 (MMP-9). RESULTS: After 24 h all subjects exhibited erythema on the DPC-treated areas. Histological evaluation of biopsies from these areas showed hydropic degeneration and a significantly increased number of MMP-9+ cells in the dermis (P < 0.0005). The MMP-9+ cells were identified with double immunofluorescence staining as CD1a + Langerhans cells. The expression of the other markers studied remained unaltered irrespective of treatment, including treatment with SLS. CONCLUSIONS: Our findings show that DPC induces an irritant reaction leading to an increased number of MMP-9+ CD1a+ cells in the dermis during the initial phase of sensitization.
Natural Herbal Supplement: Hair Million
Hair loss, or alopecia is a concern for increasing number of folks in aging society. Loss of hair is indeed a visible problem.
The phenomenon of hair thinning and hair loss is most commonly associated with natural phenomena associated with aging, there are many other causes of hair loss, which include inherited or genetic conditions, illnesses, malnutrition, stress, hormonal problems, chemotherapy, and use of some drugs.
Hair growth is a sophisticated biological process, which has not yet been completely understood. A multitude of therapeutic measures, including drugs, surgery, and suppelements have been made available, and used. However, due to the diversity of the problems underlying hair loss, there is no single solution for all hair loss cases. Most of chemical drugs and hair transplantation surgeries are not free from varying degrees of undesirable side effects on health.
Hair Million is an alternative solution to hair loss problems. Anecdotally, it shows prositive results and improvement for age-related hair thinning and hair loss for a fraction of people who take it. We do not know the mechanisms of action as to how Hair Million works to help stop hair loss, and promote hair growth. We only know by anecdotal observations. There has been no clinical trials nor placebo controlled statistical analysis on the efficacy of HairMillion on hair loss and hair growth.
Bottom line is that there are two merits in this hair restoration herbal formula:
Firstly, Hair Million is rather inexpensive, and secondly, it is made of well known herbs that are safe when consumed in regular quantities. For clinically tested prescription medication, try Buy Propecia Online.
DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones)
or estrogens (female hormones) in the cells.
Our bodies produce decreasing amount of DHEA as we get older.
various health benefits: To deter aging,
improve sexual function/erectile dysfunction, treat cognitive decline, enhance athletic performance,
facilitate weight loss, improve strength, prevent osteoporosis, enhance immunomodulation for rheumatic conditions,
and treat depression.
