Abstract
Não existem dados definitivos e consistentes sobre a real distribuição dos microorganismos presentes em pacientes com Rinossinusite Crônica (RSC). A variabilidade dos resultados de estudos em RSC deve-se às diferentes técnicas utilizadas como método de coleta, variações nos métodos de cultura, uso prévio de antibiótico, dificuldade de se distinguir agentes colonizadores e patogênicos. FORMA DE ESTUDO: Clínico-prospectivo. OBJETIVO: Estudar a incidência dos microrganismos presentes nos pacientes com RSC na nossa região, através da cultura da secreção do seio maxilar, coletada sob visão endoscópica. MATERIAIS E MÉTODOS: Estudo transversal em 62 pacientes com RSC, submetidos à coleta de secreção de seio maxilar por via endoscópica, com material enviado para cultura para diagnóstico microbiológico. RESULTADOS: Das 62 amostras estudadas, em 33 (53,2%) não houve crescimento de microrganismos; 29 (45,2%) apresentaram isolamento de aeróbios; um caso (1,6%) mostrou crescimento de fungo; não houve o isolamento de microrganismos anaeróbios. Pseudomonas aeruginosa foi isolada com maior frequência - em 8 amostras (27,6%), Staphylococcus aureus e Staphylococcus epidermidis em 4 amostras cada um (13,9%), Streptococcus pneumoniae em 3 amostras (10,4%), outros Gram-negativos em 17 amostras (31%). CONCLUSÃO: Pseudomonas aeruginosa, outras bactérias Gram-negativas e Staphylococcus spp constituíram a microbiota predominante nos seios paranasais de pacientes com RSC.
There isn't definitive and consistent data concerning the distribution of bacterial species in patients with Chronic Sinusitis (CS). The variability of the results from studies in CS may be due to the different techniques used as collection method, variations in culture methods, previous antibiotic use, and difficulty in distinguishing bacterial flora from pathogenic agents. STUDY DESIGN: Clinical prospective. AIM: To identify the incidence of microorganisms in patients with CRS by growing bacteria from the secretion of the maxillary sinus. PATIENTS AND METHODS: Cross-sectional study in 62 patients that had undergone FESS for treatment of chronic sinusitis; cultures from the maxillary sinus were obtained. RESULTS: 62 samples, 33 (53.2%) had no growth; 29 (45.2%) counts of aerobic bacteria; one case (1.6%) of fungus growth; we did not find anaerobic bacteria. Pseudomonas aeruginosa was the one more frequently found - 8 samples (27.6%), Staphylococcus aureus and Staphylococcus epidermidis in 4 samples each; Streptococcus pneumoniae in 3 samples (10.4%); other Gram negative agents in 17 samples (31%). CONCLUSION: In the present study we concluded that Pseudomonas aeruginosa, other Gram negatives bacteria and Staphylococcus spp were the representatives of the bacterial flora found in the paranasal sinuses of patients with CS.
