Lipedematous alopecia of the scalp.

Lipedematous scalp is a rare disorder, mainly described in adult African-American females. We report 2 adult caucasian males with lipedematous scalp associated with androgenetic alopecia. Patients were studied by dermoscopy and histopathology; they were treated with finasteride 1 mg. In our patients, lipedematous scalp affected the occipital and the vertex areas and pathologically exhibited mild edema and thickening of the adipose subcutaneous layer. At videodermoscopy, lipedematous scalp areas showed linear areas of teleangiectasia within the scalp creases, possibly caused by compression of the superficial blood capillaries by the increased volume of the subcutaneous fat layer within the thickened scalp. Finasteride at a dose of 1 mg per day for 1 year induced mild improvement of androgenetic alopecia in one patient and stabilization of the disease in the other. The lipedematous scalps remain unchanged. Lipedematous scalp is apparently a rare disease even though the condition is probably underdiagnosed. As a matter of fact, we diagnosed lipedematous scalp in our patients during a clinical examination for androgenetic alopecia, which was the patients' complaint. The association of lipedematous scalp and androgenetic alopecia in our two patients appears to be coincidental.

Evaluation of sexual function with an international index of erectile function in subjects taking finasteride for androgenetic alopecia.

OBJECTIVE: To evaluate variations in sexual and erectile function in subjects taking 1 mg of finasteride for androgenetic alopecia by administering the abridged 5-item version of the International Index of Erectile Function (IIEF-5) questionnaire before and during treatment. DESIGN: In a multicenter study, 186 patients with androgenetic alopecia were asked to complete the IIEF-5 regarding the domain of erectile function before (at baseline) and 4 to 6 months after beginning finasteride treatment. The test was self-administered. SETTING: The study was conducted in 7 institutional dermatology departments in Italy (Bologna, Rome, Genoa, Cagliari, Milan, Florence, and Bari). PATIENTS: A total of 186 patients with androgenetic alopecia were evaluated before and 4 to 6 months after the initiation of finasteride therapy (1 mg). All patients (age range, 19-43 years; mean age, 28.3 years) were followed up as outpatients. RESULTS: The score on each of the 5 domains of the IIEF-5 did not show any significant change after 4 to 6 months of treatment. CONCLUSIONS: Our results support the clinical impression that sexual side effects are actually much less common than reported in clinical trials. The sexual function of all patients remained stable during treatment with 1 mg of finasteride.

Hypertrichosis of the eyelashes caused by bimatoprost.

The phenyl-substituted analog of prostaglandin F 2alpha , latanoprost (Xalatan; Pfizer, Inc, New York, NY) is an intraocular pressure (IOP)-lowering drug for use in patients with glaucoma and ocular hypertension. Latanoprost has been shown to stimulate eyelash hypertrichosis and has recently been proposed as a possible treatment for alopecia areata involving the eyelashes. We report a case of hypertrichosis of the eyelashes caused by the prostamide bimatoprost (Lumigan; Allergan, Inc, Irvine, Calif), a new IOP-lowering drug.

Clobetasol propionate 0.05% under occlusion in the treatment of alopecia totalis/universalis.

BACKGROUND: Efficacy of topical steroids in alopecia areata is still discussed. OBJECTIVE: The purpose of this study was to evaluate the efficacy of clobetasol propionate 0.05% ointment under occlusion in 28 patients with alopecia areata totalis (AT) or AT/alopecia universalis. METHODS: A total of 28 patients were instructed to apply 2.5 g of clobetasol propionate to the right side of the scalp every night under occlusion with a plastic film. Treatment was performed 6 days a week for 6 months. When regrowth of terminal hair occurred, treatment was extended over the entire scalp. All patients were followed up for another 6 months. RESULTS: Of the 28 patients included in the study, 8 were treated successfully (28.5%). Regrowth of terminal hair began on the treated side 6 to 14 weeks after the start of treatment. Of these 8 patients, 3 had a relapse and were not able to maintain hair regrowth. CONCLUSION: Our study shows that clobetasol propionate 0.05% under occlusion is effective in inducing hair regrowth in patients with AT or AT/alopecia universalis. Occurrence of hair regrowth only on the treated half of the scalp clearly shows that efficacy of treatment is a result of a local and not systemic effect of the drug. Although only 17.8% of patients had long-term benefit by treatment, our results were obtained in a population of patients with severe and refractory forms of the disease.

Allergic contact dermatitis in hairdressers: frequency and source of sensitisation.

Occupational skin diseases are very common among hairdressers. The aim of our study was to evaluate the frequency, the age distribution and the source of contact sensitization in a group of 209 hairdressers who consulted our Clinic from 1990 to 1999. One hundred and thirty-two patients showed one or more clinically relevant positive reactions to different allergens; 89 of them were positive to the hairdressers' series and 43 were positive to other allergens. Para-phenylenediamine base and para-toluenediamine sulphate caused the greatest number of positive reactions (77 and 29 respectively). Both glyceryl monothioglycolate and ammonium persulphate gave 25 positive patch tests. The allergens not included in the hairdressers' series which gave the greatest number of positive reactions were nickel sulphate and disperse dyes yellow 3, blue 124 and red 1. The allergens known as strong skin sensitizers have remained almost the same over the years. Preventive measures should be mandatory to protect hands and to improve the safety of this job.
