Resumo Contexto As infecções profundas de extremidades representam um desafio para o salvamento de membro dos pacientes. Objetivos Investigar se existe concordância entre as culturas de osso e tecido profundo em pacientes com lesões tróficas de extremidades. Métodos Foi realizado um estudo retrospectivo incluindo 54 pacientes com lesões tróficas profundas de extremidades internados, no Complexo Hospitalar Universitário Professor Edgard Santos, Salvador (BA), Brasil. Foram incluídos todos os pacientes que realizaram culturas de lesões tróficas profundas, com duas modalidades de coleta de exame: osso e fragmentos de tendão profundo. Analisaram-se a concordância, o número total de microrganismos e o número de microrganismos de acordo com a coloração de Gram em ambas as amostras. Resultados Entre os 54 doentes incluídos na amostra, a média de idade foi de 63,6 anos, 80% apresentavam DAOP, 70% eram diabéticos, e 72% hipertensos. Estudando as culturas dos 54 pacientes, 28 amostras (52%) foram completamente concordantes, sendo cultivados os mesmos microrganismos nos fragmentos de tendão profundo e de osso. Houve discordância parcial em 13 amostras (24%), e discordância total em 13 (24%). Observou-se que cresceu em média 1,62 microrganismo nos fragmentos de tendão profundo, e 1,72 nas amostras de osso. Analisando separadamente os microrganismos gram-positivos, a média de espécies cultivadas foi de 0,48 em tendão e de 0,44 em tecido ósseo. Por outro lado, para os microrganismos gram-negativos, a média de microrganismos cultivados foi de 1,14 e 1,27 nas amostras de tendão e de osso, respectivamente. Conclusões Cerca de metade dos pacientes portadores de lesões tróficas profundas de extremidades apresentaram concordância total entre as culturas de osso e de tendão. Abstract Background Deep infections of the extremities are a challenge that threaten limb salvage. Objectives To investigate whether the results of bone and deep tissue cultures from patients with trophic limb ulcers coincide. Methods A retrospective study was conducted with data from 54 patients with deep trophic limb ulcers admitted to the Complexo Hospitalar Universitário Professor Edgard Santos, Salvador (BA), Brazil. The study analyzed all patients for whom cultures of material from foot wounds in patients with tissue loss had been performed using two specimen types: bone and fragments of deep tendon. The study analyzed concordance between the two sample types and total number of microorganisms and numbers of microorganisms by Gram staining in both samples. Results The mean age of the 54 patients in the sample was 63.6 years, 80% had PAOD, 70% were diabetic, and 72% were hypertensive. Analysis of the cultures showed that 28 (52%) pairs of samples from the 54 patients exhibited complete concordance, with the same microorganisms grown from fragments of deep tendon and bone. There was partial disagreement in 13 samples (24%) and total disagreement in 13 (24%). On average, 1.62 microorganisms were isolated from deep tendon fragments and 1.72 were isolated from bone samples. Analyzing Gram-positive microorganisms separately, the mean number of species grown was 0.48 for tendon cultures and 0.44 for bone cultures. In contrast, the mean number of Gram-negative microorganisms isolated was 1.14 for tendon samples and 1.27 for bone samples. Conclusions Around half of the patients with foot tissue loss had bone and tendon cultures that coincided exactly.

OBJETIVOS: descrever resistência antimicrobiana e sorotipos de cepas de pneumococo. MÉTODOS: durante 57 meses, foi conduzida uma vigilância de cepas invasivas de pneumococo de pacientes com idade

Pneumonia is one of the leading causes of hospitalization and death among children in developing countries, and mortality due to pneumonia has been associated with S. pneumoniae infection. This investigation was designed to describe the antimicrobial susceptibility and serotype patterns of pneumococcal strains recovered from the blood of children with community-acquired pneumonia (CAP) and to assess the clinical findings of pneumococcal bacteremic patients with pneumonia. In a 26 month prospective study, blood cultures were obtained as often as possible from children (16 years of age) diagnosed with CAP in two emergency rooms. Antimicrobial drug susceptibility tests and serotyping were performed when pneumococcus was identified. We studied 3,431 cases and cultured blood samples from 65.5% of those. Pneumococcus was recovered from 0.8% of the blood samples. The differences in age, somnolence, wheezing and hospitalization among children with and without pneumococcal bacteremia were statistically significant. Pneumococcal bacteremia was age-related (mean 1.63 +/- 1.55; median 0.92) and associated with somnolence and hospitalization among children with CAP. One strain was recovered from pleural fluid. Penicillin resistance was detected in 21.0% (4/19) of the strains at an intermediate level, whereas 63.0% of the strains were resistant to trimethoprim-sulfamethoxazole. The most common serotypes were 14 and 6B, and these serotypes included the resistant strains. Eight of our 18 isolates from blood were of types included in the heptavalent conjugate pneumococcal vaccine, recently licensed in the USA.

This study was a non-comparative multicenter clinical trial to evaluate the efficacy and tolerability of itraconazole oral solution 200 mg/day (100 mg twice a day in the fasting state) for the treatment of oropharyngeal candidiasis in AIDS patients. We included 50 patients who were treated and followed for up to 3 weeks after ending therapy in the analysis. Mycological cures at the end of therapy occurred in 20/50 patients (40%), but colonization by Candida sp. was recorded in 42/50 (84%) by the end of follow-up. A high rate of clinical response was observed in 46/50 (92%), and the response was sustained for up to 21 days after stopping therapy in 24/46 patients (52%). Clinical relapses were documented among 22 patients, but all causative fungal organisms associated with a relapse were susceptible to itraconazole. There were many patients with persistence or recurrence of Candida, but without mucositis. Relapse of Candida mucositis was significantly related to low levels of CD(4) lymphocytes exhibited by symptomatic patients. The drug was well tolerated by all but 1 patient. We conclude that itraconazole oral solution (100 mg bid for 7-14 days) is a well tolerated and effective treatment for suppressing the symptoms of oropharyngeal candidiasis in AIDS patients. Patients with severe immunosuppression may relapse and require frequent cycles of treatment or longterm suppressive therapy.
