Fascitis necrosante genital

Las infecciones bacterianas de la piel y partes blandas constituyen una patología frecuente como consulta en los servicios de urgencias. Los cuadros más frecuente son las celulitis, que tienen un buen pronóstico, pero ocasionalmente se ven infecciones más profundas que afectan a tejido celular subcutáneo, fascia y músculo. En este caso el diagnóstico y tratamiento precoces son fundamentales para el pronóstico del paciente. Describimos un caso de Gangrena de Fournier que a pesar del un diagnóstico y tratamiento precoces en el servicio de urgencias, produjo la muerte del paciente.

Langerhans Cells Prime IL-17-Producing T Cells and Dampen Genital Cytotoxic Responses following Mucosal Immunization

Langerhans cells (LCs) are dendritic cells (DCs) localized in stratified epithelia, such as those overlaying skin, buccal mucosa, and vagina. The contribution of LCs to the promotion or control of immunity initiated at epithelial sites remains debated. We report in this paper that an immunogen comprising OVA linked to the B subunit of cholera toxin, used as delivery vector, was efficient to generate CTLs after vaginal immunization. Using Lang-EGFP mice, we evaluated the contribution of distinct DC subsets to the generation of CD4 and CD8 T cell responses. We demonstrate that the vaginal epithelium, unlike the skin epidermis, includes a minor population of LCs and a major subset of langerin(-) DCs. Intravaginally administered Ag is taken up by LCs and langerin(-) DCs and carried up to draining lymph nodes, where both subsets prime CD8 T cells, unlike blood-derived DCs, although with distinct capabilities. LCs prime CD8 T cells with a cytokine profile dominated by IL-17, whereas Lang(-) DCs induce IFN-gamma-producing T cells. Using Lang-DTR-EGFP mice to ensure a transient ablation of LCs, we found that these cells not only are dispensable for the generation of genital CTL responses but also downregulate these responses, by a mechanism that may involve IL-10 and IL-17 cytokines. This finding has implications for the development of mucosal vaccines and immunotherapeutic strategies designed for the targeting of DCs.

Female genital mutilation in Switzerland: a survey among gynaecologists.

QUESTION UNDER STUDY: To evaluate the situation of Female Genital Mutilation (FGM) in Switzerland. METHODS: Through a questionnaire, Swiss gynaecologists were asked if they have been confronted to FGMs, if they have been asked to perform infibulations and FGMs. The health representatives (Kantonsärzte/médecins cantonaux) were interviewed on FGM activity at the Canton level. Swiss Medical Schools were asked if FGM was included in the pregraduate curriculum, and an estimated prevalence rate for FGMs in Switzerland was gathered. RESULTS: Among Swiss gynaecologists, 20% reported having been confronted with patients presenting with FGM and among them 40% had been asked about reinfibulation. Gynaecologists are occasionally asked about the possibility of performing FGMs in Switzerland. No activity concerning FGM is reported by health authorities in the Cantons. Teaching about FGM is not included in the curriculum of any of the Swiss medical schools. Approximately 6,700 girls at risk and women who have undergone FGM live in Switzerland. CONCLUSION: The extent to which gynaecologists are confronted to women with FGM may justify further action to try to better understand the situation in Switzerland. Improvement of care by better education of health care providers (guidelines) and prevention of new cases by women's education should also be considered.

Treatment of genital mycoplasma in colonized pregnant women in late pregnancy is associated with a lower rate of premature labour and neonatal complications.

Mycoplasma hominis and Ureaplasma spp. may colonize the human genital tract and have been associated with adverse pregnancy outcomes such as preterm labour and preterm premature rupture of membranes. However, as these bacteria can reside in the normal vaginal flora, there are controversies regarding their true role during pregnancy and so the need to treat these organisms. We therefore conducted a retrospective analysis to evaluate the treatment of genital mycoplasma in 5377 pregnant patients showing symptoms of potential obstetric complications at 25-37 weeks of gestation. Women presenting with symptoms were routinely screened by culture for the presence of these bacteria and treated with clindamycin when positive. Compared with uninfected untreated patients, women treated for genital mycoplasma demonstrated lower rates of premature labour. Indeed preterm birth rates were, respectively, 40.9% and 37.7% in women colonized with Ureaplasma spp. and M. hominis, compared with 44.1% in uncolonized women (Ureaplasma spp., p 0.024; M. hominis, p 0.001). Moreover, a reduction of neonatal complications rates was observed, with 10.9% of newborns developing respiratory diseases in case of Ureaplasma spp. colonization and 5.9% in the presence of M. hominis, compared with 12.8% in the absence of those bacteria (Ureaplasma spp., p 0.050; M. hominis, p <0.001). Microbiological screening of Ureaplasma spp. and/or M. hominis and pre-emptive antibiotic therapy of symptomatic pregnant women in late pregnancy might represent a beneficial strategy to reduce premature labour and neonatal complications.
