ABSTRACT
Abstract: The aim of the study was to identify Bacillus species from the Demodex folliculorum of patients with topical steroidinduced facial rosaceiform dermatitis. Of the 75 patients examined, 20% had clinical spinulosis, while 18.66% had dermoscopic features of Demodex: follicular plugs and tails. Of the 17.33% positive patients identified upon microscopy for Demodex, samples for bacterial culture were plated on trypticase soy Colombia agar. Identification was performed by microorganisms grown method mass spectrometry. We identified a strain of Bacillus cereus.

Although it is debatable whether Helicobacter pylori may play a role in the pathogenesis of rosacea, some authors suggested that the treatment of H. pylori might have a beneficial effect. The aim of this investigation was to compare the prevalence of H. pylori between rosacea patients and controls, and to evaluate an effect of H. pylori eradication on rosecea by a 2-week triple therapy that was composed of amoxicillin, clarithromycin and omeprazole. H. pylori was detected by using gastroscopic biopsy with Warthin-Starry stain. Forty-two (84%) of 50 patients with rosacea and 39 (78%) of 50 controls had H. pylori, showing no significant difference in prevalence. The cure rates of H. pylori in rosacea patients and controls were 80% (16/20) and 85% (17/20), respectively. There was no significant decrease in the intensity of erythema in active treatment and placebo groups both during and after the treatment. Temporary improvement in papulopustules exclusively during the treatment (within 2 weeks) could be independent of H. pylori eradication. Overall, no significant reduction in the number of papulopustules was observed in active treatment and placebo groups after the treatment (in 2 months). Taken together, our study found no significant lessening of rosacea lesions by treating H. pylori infection, which conclusively does not concur with a view that H. pylori may be related to rosacea.

Varón de 52 años que consulta por presentar disuria, ardor miccional y lesiones cutáneas que mejoran con una alta ingesta diaria de ácidos (vinagre y limón). En los últimos 20 años había consultado a diferentes profesionales sin encontrar la solución a su problema. Al suspender la ingesta de ácidos por indicación médica presentó disuria y lesiones cutáneas compatibles con rosácea. Por la asociación entre esta patología y la colonización gástrica com H. Pylori se realizó una endoscopia digestiva que confirmó su presencia. Se instituyó tratamiento específico con resolución completa y permanente de los síntomas. Se constató la erradicación a través de una nueva endoscopia digestiva con biopsia. Se sugiere que la conolización gástrica com H. Pylori podría estar relacionada com síntomas irritativos del tracto urinario inferior no aclarados por outra etiología.
