Case Reports
[Neutrophilic dermatosis associated with propylthiouracil-induced p-ANCA (p-antineutrophil cytoplasmic antibodies)].
We report on a patient who progressively developed polymorphic expressions of neutrophilic dermatosis (Sneddon-Wilkinson subcorneal pustulosis and pyoderma gangrenosum) associated with p-antineutrophil cytoplasmic antibodies (p-ANCA), while receiving propylthiouracil for hyperthyroidism. To our knowledge, such associations have never been published so far. ⋯ Propylthiouracil is well known to induce the occurrence of ANCA in 20 to 64p. 100 of patients treated for Graves'disease. The mechanisms involved are badly recognized so far. Cutaneous vasculitis, glomerulonephritis and polychondritis may be clinically associated with those antibodies. Rare observations of neutrophilic dermatosis, mostly Sweet's syndrome, have been described in patients with propylthiouracil-induced ANCA. One case-report described a 44 year-old woman who developed pyoderma gangrenosum associated with propylthiouracil-induced p-ANCA. These manifestations usually appear within 2 years, as our patient. The data in the literature, allows us to report the polymorphic expressions of neutrophilic dermatosis in this patient with p-ANCA which could be related to propylthiouracil. Such association of Sneddon-Wilkinson subcorneal pustulosis and pyoderma gangrenosum with p-ANCA has never been described in this endocrinologic context so far. Furthermore we propose that neutrophilic dermatosis should be inscribed in the list of side effects induced by propylthiouracil therapy.

The aim of this study was to assess the prevalence of sexually transmitted infections among patients attending an anonymous HIV Screening Center. ⋯ Classical sexually transmitted infections and HIV infection were rarely detected in this study; but prevalence of other sexually transmitted infections (genital warts, Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum) was high. Ureaplasma urealyticum is considered as a possible pathogenic agent in pregnant women (preterm delivery, decrease of birth weight, chorioamniotitis). These results suggest that other than sexually transmitted infections in high risk patients attending a HIV Screening Center other sexually transmitted infections should also be systematically screened for.
