Acute Diffuse and Total Alopecia of the Female Scalp. a new subtype of diffuse alopecia areata that has a favorable prognosis.

Background: Athough alopecia areata (AA) usually starts with focal lesions of hair loss and then presents several different clinical forms, AA may begin as diffuse hair loss. We examined 9 female patients who presented with acute, diffuse and total hair loss of the scalp and took a similar clinical course with a favorable prognosis. Objective: To categorize such cases as a new subgroup of diffuse alopecia. Methods: We studied 9 patients who showed acute, diffuse and total hair loss of the scalp within 1 month after their first visit to our hospital by comparing their clinical course, laboratory tests and histopathological findings with those of common, patchy AA, alopecia totalis or alopecia universalis. Results: None of the patients had a background of systemic diseases or telogen effluvium. All the patients were female, and 8 of the 9 cases recovered cosmetically acceptable hair growth within 6 months regardless of steroid administration. The histology of he lesions was indistinguishable from that of AA except for a remarkable eosinophilic infiltrate. Conclusions: These cases can be categorized as a new subtype of inflammatory noncicatricial alopecia that is characterized by a marked female predominance, tissue eosinophilia and uniquely short clinical course. We suggest to name it 'acute diffuse and total alopecia of the female scalp (ADTAFS)'.

A random study of Asian male androgenetic alopecia in Bangkok, Thailand.

BACKGROUND: Androgenetic alopecia remains the most common cause of male pattern baldness (MPB) in all races. The prevalence of MPB in Caucasians is well documented. The prevalence of MPB in Asians is believed to be very low, only one-fourth to one-third on average compared to Caucasians. However, according to my previous study, there is a clear trend indicating that it is approaching that of Caucasians. OBJECTIVE: To assess the prevalence of MPB in the Asian population in Bangkok, Thailand; to compare this prevalence to previous studies conducted on Asians; and to compare the results to previous studies conducted on Caucasian. METHODS: This study was conducted by two physicians and assisted by two registered nurses. The questionnaire included age, sex, Norwood classification, diet, family history of baldness, income, and education. The physicians examined the scalp of each interviewee upon completion of each questionnaire. The ethnic focus group in this study was Thai and Chinese who reside in Bangkok, Thailand. The interviews were conducted in hospitals, nursing homes, classroom, medical meetings, temples, parks, and villages. RESULTS: A total of 1124 men were randomized in this study. The prevalence of cosmetically significant MPB (Norwood III-VII) was 38.52% and steadily increasing with age, approaching that of Caucasians. Variant MPB was found to be 0.67% and other types of androgenetic alopecia was 0.6%. From an ethnic point of view, the majority of the groups were of mixed blood and mostly of Chinese origin, thus we were unable to distinguish between Chinese and Thai. CONCLUSION: This study shows that the prevalence of MPB in Asians is not as low as previously thought. The cause of this increasing prevalence is uncertain. There are no past studies in Thailand for comparison, however, it can be extrapolated that the socioeconomic environment and westernized diet may contribute to this prevalence.

Defolliculated (dfl): a dominant mouse mutation leading to poor sebaceous gland differentiation and total elimination of pelage follicles.

Defolliculated is a novel spontaneous mouse mutation that maps to chromosome 11 close to the type I keratin locus. Histology shows abnormal differentiation of the sebaceous gland, with the sebocytes producing little or no sebum and undergoing abnormal cornification. The hair follicles fail to regress during catagen leading to abnormally long follicles. In contrast the hair shafts are shorter than normal, suggesting altered differentiation or proliferation of matrix cells during anagen. The shafts emerge from the follicle with cornified material still attached. The dermis contains increased numbers of immune cells, including T cells (CD4-positive), macrophages, and mast cells, at all time points examined. Complete elimination of all pelage and tail follicles occurs after two to three hair cycles, apparently by necrosis. Defolliculated may be a useful model for determining further functions of the sebaceous gland, and for understanding the regulation of catagen and hair follicle immunology.

Photographic documentation of the effectiveness of 1 mg. oral finasteride in treatment of androgenic alopecia in the man in routine general practice in Switzerland

A 6-month, prospective, open, multicenter cohort study in 265 men with male pattern hair loss treated with oral finasteride 1 mg/day (Propecia) was conducted in the office of 52 Swiss dermatologists. The patient's head was placed in a stereotactic device, and Polaroid photographs were taken of the vertex and frontal areas. Endpoints used to determine treatment efficacy were patient self-assessment, investigator clinical assessment, and blinded assessment of the serial Polaroid photographs by a panel of 2 experienced dermatologists. Significant improvements were stated on the photographs by both clinical investigators and the blinded expert panel: 54% of patients showed improvement of hair growth at 6 months of treatment in the vertex region, and 48.7% in the frontal area. No progression of hair loss was found in an additional 38% (vertex) and 47% (frontal region), respectively. Clinical investigator and expert assessment yielded comparable results. Independently, patient self-assessment and investigator clinical assessment confirmed the progress. Propecia was well-tolerated, and no significant safety concerns were identified during the study. The photographic method was well accepted by the physicians. The office-based Polaroid photographic system allowed reliable assessment of change during treatment of male pattern hair loss with Propecia. The data generated in this manner corresponded to the antecedent results of the multicenter, placebo-controlled studies with oral finasteride.

Sudden hair loss and baldness is a problem in many ways. Baldness is indeed becoming an increasing concern in the current aging society.

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.
