RESUMEN

BACKGROUND: Dissecting cellulitis of the scalp (DCS) is a rare and long-standing disease and its aetiopathogenesis remains unclear. Various therapeutic alternatives exist. We attempted to assess the efficacy of oral isotretinoin in a series of patients. PATIENTS AND METHODS: Seven cases of DCS followed and treated by one of the authors at the Sabouraud Centre in the Saint-Louis Hospital between 2007 and 2013 were retrospectively studied and the efficacy of oral isotretinoin was evaluated. RESULTS: The seven patients included were males aged between 22 and 39 years, with alopecic nodules on the occiput (two cases) or the top of the vertex (five cases). Most patients were given oral isotretinoin at a dosage of 0.75mg/kg/day for at least nine months. The outcome was satisfactory with complete healing of the lesions and good regrowth in all cases. Follow-up after recovery lasted between 16 and 42 months. CONCLUSION: Based on published studies and the results of the present study, oral isotretinoin at a dose of 0.75mg/kg/day may be proposed as first-line treatment for DCS.

RESUMEN

INTRODUCTION: The aim of this study was: 1) to evaluate the rate of micro-organism isolation in 100 patients consulting for balanitis at the Centre of sexually transmitted diseases at the St. Louis Hospital in Paris in comparison with that of micro-organisms isolated in 60 men without balanitis; 2) to search for a possible correlation between the clinical aspect of the disease and the nature of the infectious agent identified. METHODS: One hundred consecutive patients were included in the study. All underwent a clinical examination and samples were taken for bacteriology, mycology and virology examinations. Sixty healthy volunteers served as controls. Two samples were taken from the balanopreputial groove in search for fungi and bacteria. RESULTS: Candida albicans (CA) was isolated in 33 p. 100 of the patients. A pathogenic bacteria (beta-haemolytic streptococci, Staphylococcus aureus, Klebsiella), or a potentially pathogenic germ (Haemophilus parainfluenzae, anaerobic bacteria, Gardnerella vaginalis, Streptococcus milleri, group HB5) was found without CA in 28 p. 100 of the cases, a commensal flora (enterobacteria, group D streptococci) was found without CA in 8 p. 100 and in 31 p. 100 of the cases non causal agent could be identified. DISCUSSION: This series confirms the non-pathogenic nature of commensal bacteria: the number of isolations was similar in the subjects with and without balanitis (p < 0.9). The role played by the other bacteria in the development of balanitis is discussed: saprophytic association or direct pathogenesis? The significant difference in the rate of bacteria isolations in patients with balanitis compared with controls (p < 0.001) is in favour of a pathogenic role. The clinical presentation was not predictive of the presence of any particular micro-organism excepting the presence of pustules which were highly suggestive of candidiasis.

RESUMEN

A chemiluminometric immunoassay (Magic Lite Chlamydia) for detection of Chlamydia trachomatis antigens in first-void urine samples was compared with cell culture using urogenital swabs from 221 men and 242 women. The rate of isolation of Chlamydia trachomatis was 23.5% in men, nearly 80% of whom had symptoms of urethritis, and 8.3% in women, in whom both cervix and urethra samples were tested. In urine sediments from men and women respectively the chemiluminometric assay showed a sensitivity of 80.8% and 70%, a specificity of 97% and 95%, a positive predictive value of 89.4% and 58.3%, and a negative predictive value of 94.3% and 97.2%. Discrepancies between results obtained with the chemiluminometric assay and cell culture were resolved using two polymerase chain reaction techniques to test urogenital samples. The detection of Chlamydia trachomatis in urine samples with the chemiluminometric assay was confirmed to be superior for screening symptomatic men with urogenital infections than women as a lower prevalence population.

RESUMEN

A search for Chlamydia trachomatis by cell culture was carried out in the urethra of 82 male patients consulting for condyloma acuminata at the Clinical and Biological Centre for Sexually Transmissible Diseases of the Saint-Louis hospital, Paris. Three patients had discreet urethral signs, but none had urethral discharge. Cell culture was positive for C. trachomatis in 36 of the 82 patients (44 percent). This high prevalence suggests that C. trachomatis should systematically be looked for in the urethra of male patients consulting for condylomata acuminata. If this cannot be done, then a systematic treatment with tetracyclines should be instituted.

RESUMEN

We report an unusual case of penile carcinoma in situ in a heterosexual man. The histologic study showed a severe dysplasia, and the typing of human papillomavirus DNA, performed at the Pasteur Institute, disclosed a type 18, which is usually associated with penile and cervical carcinomas. The identification of an oncogenic human papillomavirus type in the penile lesions, such as type 18 found in this case, should lead to a search for cervical carcinoma in the sexual partner.
