Streptococcus pneumoniae resistance to penicillin was studied in two hospitals in Caxias do Sul, Rio Grande do Sul, Brazil, between May 1998 and November 2001. From the 176 strains of invasive Streptococcus pneumoniae that were identified, 2.28% (CI 0.62-5.74) presented intermediate resistance, and 3.42% (CI 1.26-7.31) presented high-level resistance. Conclusion was that the use of penicillin in Caxias do Sul was still justified as treatment of pneumococcal pneumonia, differently from other centers where the penicillin was replaced by other antibiotics. These results confirm the statement of IDSA (Infectious Diseases Society of America) guideline for the management of community-acquired pneumonia in adults, that the choice of antimicrobial drug to treat pneumococcal pneumonia should be guided by local or regional prevalence of resistance to penicillin.

Introduction: Inhalations, postural drainage and respiratory physiotherapy are not always effective in removing tracheobronchial secretions. Objectives: To evaluate an alternative surgical technique, modified crichothyroidotomy, to aspirate tracheobronchial secretions. Method: Modified crichothyroidotomy is the introduction of a catheter number 8, 10 or 12 into the crichothyroid membrane in order to stimulate coughing and the aspiration of secretions. This is a descriptive study of the benefits as well as immediate and late complications caused by the use of this technique in 45 patients with excessive tracheobronchial secretions inadequately removed by usual methods. Results: Immediate surgical complications were bleeding (10 patients), oropharynx deviation (3), subcutaneous emphysema (1) and difficult introduction (1). Mean catheter permanence was 14 ± 16 days and, in all cases, the catheter provoked coughing and allowed the easy aspiration of secretions. The most frequent occurrence (17 patients) was the expulsion of the catheter by coughing, inadequate catheter handling during aspiration and moving of the patients. Conclusion: This is a simple technique with a low morbidity rate and represents constitutes an effective alternative to be used in the aspiration of tracheobronchial secretions.
