ABSTRACT
O objetivo deste trabalho foi determinar a frequência e o perfil de susceptibilidade a antimicrobianosde Streptococcus em faringotonsilite aguda recorrente. Para o estudo foram coletadas tonsilas de122 pacientes com idade entre 3 e 38 anos (66 pacientes do sexo masculino e 56 do sexo feminino)com histórico de faringotonsilite aguda recorrente, associada à hipertrofia tonsilar, e submetidosà tonsilectomia em um hospital escola. Após isolamento e identificação bacteriana, testes deantibiograma foram realizados para determinar o perfil de susceptibilidade a antimicrobianos. Foram isoladas e identificadas 151 amostras bacterianas pertencentes ao gênero Streptococcus.Destas, 41,1 por cento foram identificadas como Streptococcus grupo viridans não hemolítico; 39,1 por cento como Streptococcus grupo viridans a-hemolítico; 7,3 por cento como Streptococcus dos grupos C, F ou G;5,3 por cento como Streptococcus spp. Beta-hemolítico; 4,6 por cento como Streptococcus spp. não hemolítico; 1,3 por cento como Streptococcus spp. grupo a-hemolítico e 1,3 por cento como Streptococcus Beta-hemolíticos do grupo A. Observou-se nos testes de antibiograma resistência aos antibióticos Beta-lactâmicos. É importante omonitoramento da microbiota que coloniza a orofaringe, visto que alguns de seus componentes têmse tornado resistentes aos medicamentos mais utilizados no tratamento das faringotonsilites, o quepode contribuir para os processos de recidiva.
The aim of this study was to determine the frequency and the antimicrobial susceptibility profileof Streptococcus spp. obtained from recurrent acute pharyngo-tonsillitis. For this study, tonsilsfrom 122 patients ranging from 3 to 38 years old (66 males and 56 females) were collected. Allpatients had a history of recurrent acute pharyngo-tonsillitis associated with tonsillar hypertrophyand were submitted for tonsillectomy at a teaching hospital. After isolation and identification,antimicrobial susceptibility tests were performed. A hundred and fifty one isolates of Streptococcusspp. were obtained from tonsils, consisting of 41.06 percent non-hemolytic Streptococcus viridans group,39.07 percent a-hemolytic Streptococcus viridans group, 7.30 percent Streptococcus of C, F or G groups, 5.30 percent beta-hemolytic Streptococcus spp., 4.63 percent non-hemolytic Streptococcus spp., 1.32 percent a-hemolytic Streptococcus spp. and 1.32 percent group A beta hemolytic Streptococcus. Some of the isolates were resistantto beta-lactamic antibiotics. The study showed that components of the oropharynx microbiotapresented resistance to drugs commonly used to treat pharyngo-tonsillitis infections. Correctdiagnosis would improve treatment and could prevent recurrent infections.

Introduction: In recent years, there has been a reduction in mortality rates in neonatal intensive care units (NICUs) due to the impact of modern technological advances in the perinatal field. As a consequence, prolonged orotracheal intubation is used more frequently, and there has been an increase in acquired subglottic stenosis (SGS) in children. Subglottic stenosis is a narrowing of the endolarynx and one of the most common causes of stridor and respiratory distress in children. The laryngoplasty balloon has proven effective in dealing with stenosis both as primary and secondary treatments, after open surgery, with the added advantage of being less invasive and not requiring external access. Materials and Methods: This study involved children from pediatric intensive care units or NICUs suffering from respiratory distress and who presented an endoscopic diagnosis of Myer and Cotton grade I to III SGS. These patients underwent balloon laryngoplasty with different numbers of interventions depending on the response in each individual case. Results All the patients responded satisfactorily to the balloon laryngoplasty. None required tracheostomy after treatment and all remained asymptomatic even after 6-month follow-up. One patient required just 1 dilation, 4 required 2, 3 underwent the procedure 3 times, and another had 5 dilations. Conclusion: The experience presented here is that of balloon laryngoplasty postorotracheal intubation SGS with very satisfactory results at a tertiary care pediatric hospital. Although the number of patients is limited, our incidence corroborates other studies that demonstrate the efficacy and safety of balloon dilatation in the treatment of SGS...
