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.

Androgenetic alopecia and prostate cancer: findings from an Australian case-control study.

The purpose of this study was to examine the relationship between androgenetic alopecia (AA) and prostate cancer with particular emphasis on early age at diagnosis and higher grade tumors. We conducted an age-stratified, population-based case-control study in Australia of men who were diagnosed before 70 years of age during 1994-1997 with histopathology-confirmed adenocarcinoma of the prostate, excluding well-differentiated tumors. Controls were selected from the electoral rolls, and the frequency was matched on age. After excluding subjects with missing values, the analysis was based on 1446 cases and 1390 controls of whom direct observations were made of their pattern of AA during face-to-face interviews. Our data suggest an association between prostate cancer and vertex baldness; compared with men who had no balding, the adjusted odds ratio (OR) was 1.54 (1.19-2.00). No associations were found between prostate cancer and frontal baldness or when frontal baldness was present concurrently with vertex baldness. The ORs were 0.98 (0.79-1.23) and 1.14 (0.90-1.45), respectively. The highest ORs were for high-grade disease in men 60-69 years of age: 1.80 (1.02-3.16) for frontal baldness; 2.91 (1.59-5.32) for vertex baldness; and 1.95 (1.10-3.45) for frontal and vertex baldness. This association between the pattern of AA and prostate cancer points to shared androgen pathways that are worthy of additional investigation.

A randomized, double-blind, placebo-controlled trial to determine the effectiveness of botanically derived inhibitors of 5-alpha-reductase in the treatment of androgenetic alopecia.

BACKGROUND: Androgenetic alopecia (AGA) is characterized by the structural miniaturization of androgen-sensitive hair follicles in susceptible individuals and is anatomically defined within a given pattern of the scalp. Biochemically, one contributing factor of this disorder is the conversion of testosterone (T) to dihydrotestosterone (DHT) via the enzyme 5-alpha reductase (5AR). This metabolism is also key to the onset and progression of benign prostatic hyperplasia (BPH). Furthermore, AGA has also been shown to be responsive to drugs and agents used to treat BPH. Of note, certain botanical compounds have previously demonstrated efficacy against BPH. Here, we report the first example of a placebo-controlled, double-blind study undertaken in order to examine the benefit of these botanical substances in the treatment of AGA. OBJECTIVES: The goal of this study was to test botanically derived 5AR inhibitors, specifically the liposterolic extract of Serenoa repens (LSESr) and beta-sitosterol, in the treatment of AGA. Subjects: Included in this study were males between the ages of 23 and 64 years of age, in good health, with mild to moderate AGA. RESULTS: The results of this pilot study showed a highly positive response to treatment. The blinded investigative staff assessment report showed that 60% of (6/10) study subjects dosed with the active study formulation were rated as improved at the final visit. CONCLUSIONS: This study establishes the effectiveness of naturally occurring 5AR inhibitors against AGA for the first time, and justifies the expansion to larger trials.

PUVA treatment of alopecia areata totalis and universalis: a retrospective study.

The results of PUVA treatment of alopecia areata (AA) totalis and universalis were reviewed in 26 adult patients. Eight of 15 patients with AA totalis and six of 11 patients with AA universalis achieved a complete response (>90% hair regrowth). Patients with AA totalis had a greater incidence of treatment failure (<25% hair regrowth) than those with AA universalis. Patients with a family history of AA were significantly less likely to have a positive response to PUVA than those with no family history. Sex, age at diagnosis and treatment, interval between diagnosis and treatment, and background of atopy were not significant determinants of outcome. Although unable to show significance for clinical response to treatment, this study demonstrates complete hair regrowth in patients with both AA totalis (53%) and universalis (55%) while reporting a low relapse rate among these patients (21%) within a long period of follow up (mean 5.2 years).

Are you losing hair gradually or all of a sudden ? Hair Million is a herbal formula to address hair loss problems. Numerous anecdotal cases demonstrate that this herbal formula based on Chinese herbs actually improves the age-related hair thinning and hair loss for a significant fraction of people taking it regularly. The biology of hair growth is complex and a field still in progress. We don't know how Hair Million stops hair loss, and promotes hair restoration, despite all the anecdotal observations. Neither scientific research nor placebo controlled clinical trials has been conducted due to the cost. Shortage of scientific/clinical research is not uncommon in herbal/nutritional arena. Hair Million is relatively inexpensive, and secondly, it is made only of traditional herbs that promote hair growth that are widely known to be safe in regular quantities. For clinically tested prescription medication, check Propecia.
