INTRODUCTION: The role of hyperandrogenism in acne occurring or persisting in adult women is controversial. Studies reported have often been carried out in hospital settings. The aim of this nationwide prospective and descriptive study was to evaluate the frequency of clinical hyperandrogenism in a large number of adult acneic women visiting dermatologists in a non-hospital setting. PATIENTS AND METHODS: Three hundred and fifteen dermatologists completed clinical questionnaires concerning the next five female patients with acne at their private practices. These patients had to be between 25 and 45 years of age. The questionnaire covered patients' demographic characteristics, medical history, gynaecological status and acne history. Patients' acne, seborrhea and cycle disorders were described, as well as other signs suggesting hyperandrogenism, such as hirsutism and alopecia. RESULTS: A total of 1 135 questionnaires were analyzed. Nearly 50 p. 100 of the patients had major scalp or facial seborrhea, 18.4 p. 100 hirsutism, 7 p. 100 alopecia and 32.2 p. 100 menstrual cycle abnormalities. When these signs were present, acne was more often retentional, with more scarring and more widespread. CONCLUSION: This prospective study in a large number of patients in a non-hospital setting shows that acne in adult women is frequently associated with clinical hyperandrogenism.

Thyroid function was assessed in euthyroid dogs (n = 20), dogs suffering from canine recurrent flank alopecia (CRFA, n = 18), and hypothyroid dogs (n = 21). Blood samples obtained from all dogs in each group were assayed for total thyroxine (TT4), thyrotropin (TSH), and thyroglobulin autoantibody (TgAA) serum concentrations. Total T4 and TSH serum concentrations were significantly decreased and increased, respectively, in the hypothyroid group compared with the other 2 groups. No significant differences in TT4 and TSH serum values were found between the euthyroid and CRFA groups. Thyroglobulin autoantibodies were detected in 10, 11.1, and 61.9% of euthyroid dogs, dogs with CRFA, and hypothyroid dogs, respectively. In conclusion, dogs suffering from CRFA have a normal thyroid function, and the determination of TT4 and TSH serum concentrations allows differentiation of these dogs from dogs with hypothyroidism, in most cases. Occasionally, the 2 diseases can be concomitant.

A computer-morphing procedure was used to produce a "full cranial hair" photograph for comparisons of perceptions by 96 undergraduates of a photograph of a naturally bald 30-yr.-old man on 13 dependent measures derived from 30 semantic differential scales. Analysis showed the full-hair condition was rated significantly more dominant, dynamic, and masculine than the bald condition. While the model was also perceived as younger in the full-hair condition, there was no difference in mean ratings of attractiveness between photographs.
