Vulvoperineal reconstruction with a sulcus gluteus flap.

Objective: To describe vulvoperineal reconstruction with a flap of the sulcus gluteus.

Study Design: Nonrandomized, prospective study in patients with vulvar cancer and vulvar intraepithelial neoplasia. After oncologic surgery, reconstruction with a sulcus gluteus flap was performed.

Genotypic and phenotypic characterization of Staphylococcus aureus strains isolated in subjects with atopic dermatitis. Higher prevalence of exfoliative B toxin production in lesional strains and correlation between the markers of disease intensity and colonization density.

Staphylococcus aureus strains generally colonize eczematous lesions of subjects with atopic dermatitis much more frequently than in the skin of normal individuals. The aim of this study was to provide a detailed genotypic and phenotypic analysis of S. aureus strains colonizing four different sites (lesional and non-lesional skin areas, nasal and pharyngeal mucosas) of 49 patients with atopic dermatitis.

Heterogeneity of oral isolates of Candida albicans in HIV-positive patients: correlation between candidal carriage, karyotype and disease stage.

Opportunist infections involving Candida albicans often develop in HIV-positive patients and oral lesions tend to become more frequent as the disease progresses. Previous studies have shown contrasting results concerning the variability of the pulsed-field gel electrophoresis (PFGE) subtypes of C. albicans observed in HIV-positive patients.

S. aureus PFGE patterns of lesional or non lesional strains from patients with impetigo: association of individual bands with lesional or non lesional areas.

PFGE has been extensively used to obtain a reliable intra-species differentiation, although this technique has not been completely standardized. In this study, PFGE was applied to analyze in detail the patterns of 19 lesional S. aureus strains isolated from patients with impetigo, compared with 15 non-lesional strains isolated from nasal or pharyngeal swabs of the same patients.

Association between lesional or non lesional S. aureus strains from patients with impetigo and exfoliative toxin production. No association with SmaI PFGE patterns.

Contrasting data are reported in the literature on the percent positivity rates (13.5%-100%) of exfoliative toxin (ET) production by S. aureus strains isolated from impetigo patients in Japan and in France.
