ABSTRACT
A pitiríase liquenoide é dermatose incomum, idiopática, com espectro clínico-histopatológico onde inclui a forma varioliforme aguda (doença de Mucha-Habermann), sua variante febril úlceronecrótica e a forma crônica. Manifestações sistêmicas podem ocorrer na variante febril úlcero-necrótica, com relatos de casos fatais em adultos. Relata-se o caso de um paciente jovem, com diagnóstico clínico e histopatológico de doença de Mucha-Habermann, variante febril úlcero-necrótica, e acometimento mucoso exuberante, fato ocasional, mesmo nas formas mais graves de pitiríase liquenoide. Além do aspecto clínico inusitado, demonstra-se excelente resultado terapêutico, com a associação de prednisona e metotrexato.
Pityriasis lichenoides is a rare idiopathic cutaneous disorder, with a clinical-histopathological spectrum comprising the acute varioliform form (Mucha-Habermann's disease), its febrile ulceronecrotic variant, and its chronic form. Systemic manifestations may occur in the febrile ulceronecrotic variant, with reports of adult mortality. The case of a young male patient with clinical and histopathological diagnosis of Mucha-Habermanns disease, febrile ulceronecrotic variant, with severe mucosal involvement - an occasional incidence even in the most severe forms of pityriasis lichenoides - is presented. In addition to the atypical clinical aspect, an excellent therapeutic result is shown with the association of prednisone and methotrexate.

OBJECTIVE: To determine the prevalence of pneumococcus colonization among HIV-infected outpatients aged 0 to 18 years. To determine the resistance to penicillin of the microorganisms observed, to identify their serotypes, and to determine whether there are associations between known risk factors and colonization in this group. MATERIAL AND METHOD: This was an observational and cross-sectional study in which nasopharynx swabs were collected from 112 children on the occasion of their monthly appointments and a questionnaire applied to the mothers. The material collected was processed at the microbiology laboratory of the hospital in accordance with National Committee for Clinical Laboratory Standards (NCCLS) regulations and serotyping was performed at the Centers for Diseases Control and Prevention (CDC). Data were analyzed statistically using the chi-square test and with univariate and multivariate analysis with multiple logistic regression. RESULTS: The prevalence rate of nasopharyngeal colonization by pneumococci was 28.6%, with a 15.6% rate of resistance to penicillin (6.2% intermediate resistance and 9.4% full resistance). The serotypes identified were 6A, 6B, 7C, 9V, 11A, 13, 14, 15A, 16F, 18C, 19B, 19F, 23B, 23F, and 34. In this population there were no associations between pneumococcal colonization and the risk factors studied. CONCLUSIONS: The prevalence of pneumococcal colonization among HIV-infected children at our service was not higher than prevalence rates observed in healthy children and reported in the literature.
