Seroprevalence of Legionella pneumophila in pneumonia patients in four major hospitals in Trinidad and Tobago / Seroprevalencia de la legionella pneumophila en pacientes con neumonía en los cuatro hospitales principales de Trinidad

Trinidad and Tobago is an island-state in the Caribbean with a size of 5,128 square kilometers and a population of 1.3 million. Pneumonia is a leading cause of death in Trinidad. This project determined the frequency of Legionella pneumophila in patients with pneumonia, investigated the relationship between pneumonia and selected risk factors. Serum and demographic data were collected from 123 patients, diagnosed with pneumonia. Sera were tested for L pneumophila Ig G/M/A and IgM. All analyses were done using the SPSS statistical package. Of a total of 123 serum samples tested, 39 (31.7) were positive for L pneumophila IgM/G/A while 2 (1.6) were positive for IgM only. Hospitals, gender and ethnicity did not significantly (p > 0.05; chi-squared) affect the seroprevalence of L pneumophila. Overall, the prevalence of L pneumophila assayed was not significantly (p > 0.05, chi-squared) affected by co-morbidities.

Trinidad and Tobago es una isla del Caribe que posee una extension de 4828 kilometros cuadrados y una poblacion de 1.3 millones. La neumonia es una de las principales causas de muerte en Trinidad. Este proyecto determino la frecuencia de Legionella pneumophila en pacientes con neumonia, e investigo la relacion entre la neumonia y los factores de riesgo seleccionados. Se recopilaron datos sericos y demograficos de 123 pacientes, diagnosticados con neumonia. Los sueros fueron sometidos a analisis a fin de determinar la presencia de L. pneumophila Ig G/M/A y Ig M. Todos los analisis se realizaron usando el paquete estadistico SPSS (Statistical Package for the Social Sciences). De un total de 123 muestras de suero analizadas, 39 (31.7%) dieron positivas frente a L. pneumophila Ig M/G/A, mientras que 2 (1.6%) dieron positivo frente a Ig M solamente. Los hospitales, el genero y la etnicidad no afectaron significativamente la seroprevalencia de L. pneumophila (p > 0.05; c2). En general, la prevalencia de L. pneumophila ensayada no fue afectada significativamente por comorbidades (p > 0.05, c2).

Percutaneous endoscopic gastrostomy in Trinidad and Tobago

Percutaneous endoscopic gastrostomy tube placement is rapidly becoming the preferred method of gastrostomy tube placement. We describe our experience with this procedure in nine patients. The main complications were minor and due to local infection. This report demonstrates the simplicity and safety of this technique
