- ItemEmpyema and pleural efussion in children(2007) Arancibia G., M. Francisca; Vega Briceno, Luis E.; Pizarro G., M. Ester; Pulgar B., Dahiana; Holmgren P., Nils; Bertrand N., Pablo; Rodriguez C, Jose I.; Sinchez D., IgnacioIntroduction: Pleural empyema (PE) is a serious complication of community-acquired pneumonia (CAP). Objectives: To describe the clinical profile of hospitalized patients with PE in the pediatric ward of the Catholic University Hospital between 2000-2005. Patients y methods: Retrospectively, all pediatric admission due to CAP and pleural effusion (86 children) were identified. In 59 (70%) children >= 1 thoracocentesis were performed. We considered PE as the presence in the pleural effusion of pus, and/or a positive gram strain and/or positive culture, and/or a pH < 7.10. Children with effusions not meeting any criteria were used as controls. Results: Twenty four PE and 25 controls were identified, with a global mean age of 2.9 years (range: 8 months to 14.3 years); 78% were < 5 years, with a significant difference between PE and controls [1.6 vs 3.3 years (p = 0.01)]. The mean duration of symptoms in PE patients before admission was 7 days (range: 2-21), and the most frequent symptoms were fever (100%) and cough (96%). In 15/24 cases a microorganism was identified being Streptococcus pneumoniae (n = 9) the most common. In 48 patients management was conservative and in 4 surgical procedures were required. The mean duration of hospitalization was significantly higher in the PE group vs controls group: 15 (range: 5-38) vs 9 days (range 3-16) (p < 0.01). A chest tube was inserted in 83% of children with EP compared with 36% in the control group (p = 0.002). There were no difference in number of days of oxygen use [6 vs 4.5 (p = 0.36)] or number of chest tubes per child [3 vs 2.5 (p = 0.29)]. No deaths were reported. Conclusion: PE in children represented an acute respiratory event associated with more prolonged hospitalization especially at younger ages; the majority of cases did not require surgical intervention.
- ItemFactores pronósticos, evolución y mortalidad en el adulto inmunocompetente hospitalizado por neumonía neumocócica adquirida en la comunidad(2009) Saldías Peñafiel, Fernando; Viviani García, Paola; Pulgar B., Dahiana; Valenzuela Flores, Francisco Felipe; Paredes Engber, Sebastián; Díaz Patiño, OrlandoBackground: Streptococcus pneumoniae is the main cause of community-acquired pneumonia in adults. Aim: To describe baseline characteristics, risk factors and clinical outcomes of adult patients hospitalized with pneumococcal pneumonia. Material and methods: Prospective study of adult patients admitted for a community acquired pneumonia in a clinical hospital. Immune deficient patients and those with a history of a recent hospitalization were excluded. Results: One hundred fifty one immuno-competent patients, aged 16 to 92 years, 58% males, were studied. Seventy-five percent had other diseases, 26% were admitted to the intensive care unit and 9% needed mechanical ventilation. There were no differences in clinical features, ICU admission or hospital length of stay among bacteremic and non-bacteremic patients. Thirty days lethality for bacteremic and non-bacteremic patients was 10.9% and 11.5%, respectively. The predictive values for lethality of Fine pneumonia severity index and CURB-65 (Confusion, Urea nitrogen, Respiratory rate, Blood pressure, 65 years of age and older) had an area under the ROC curve of 0.8 and 0.69, respectively. Multivariate analysis disclosed blood urea nitrogen over 30 mg/ dL (odds ratio (OR), 6.8), need for mechanical ventilation (OR, 7.4) and diastolic blood pressure below 50 mmHg (OR, 3.9), as significant independent predictors of death. Conclusions: Pneumococcal pneumonia was associated with a substantial rate of complications and mortality. Clinical presentation and outcome did not differ significantly among patients with and without bacteremia.
