Tuberculosis-HIV/AIDS frequency and atypical Mycobacterium-HIV/AIDS' association were very similar. The most frequently isolated atypical mycobacterium specie in this study was MAC. Survival rate was lower for patients infected by M. tuberculosis and even lower when a multi-resistant strain was involved. The most important clinical factor associated with M. tuberculosis was the presence of fever and loss of weight with mycobacterial infection. Blood provided the best samples for isolating mycobacteria.

BackgroundChagas disease (CD) is endemic in Latin America and particularly common in Bolivia, but there is little information on the characteristics of chronic digestive involvement.ObjectivesTo determine the prevalence and characterize digestive manifestations in chronic CD patients in Cochabamba, Bolivia.MethodsEighty-five T. cruzi-seropositive individuals with or without digestive symptoms (G1 group), and fifteen T. cruzi-seronegative patients with similar digestive symptoms to those seen in CD (G2 group) were included in the study. All patients underwent a detailed history including past medical history, epidemiological information, hygiene and dietary habits, a complete physical examination, two serological tests for T. cruzi, video endoscopy, barium swallow, and barium enema.FindingsWe observed digestive manifestations in T. cruzi seropositive and seronegative patients. Colonic manifestations were detected in both groups, highlighting the relevance of other confounder factors in the region. Constipation was present in 52.9% of G1 patients, 62.4% presented two or more upper digestive tract symptoms, and 5.9% of them presented esophageal manifestations. Helicobacter pylori infection was detected in 58.8% of G1 patients, and all patients presented gastritis on endoscopy.ConclusionsPrevalence of digestive involvement in CD patients is higher than expected. However, digestive symptoms are not always caused by T. cruzi infection and require differential diagnoses.

Con el fin de comparar la eficacia y seguridad de dos regímenes terapéuticos (clindamicina-gentamicina y pefloxacinametronidazol) en el tratamiento de la endometritis post-cesárea, se incluyeron 71 pacientes que fueron sometidas a parto abdominal de urgencia en el Instituto Materno Infantil del 1 de septiembre de 1993 al 31 de agosto de 1994 y que presentaron endometritis post-cesárea diagnosticada por la presencia de tres de nueve criterios utilizados en el Servicio de Sépticas. Se asignaron de manera aleatoria a uno de los dos grupos de tratamiento: gentamicina-clindamicina o metronidazol-pefloxacina. Se estudió la eficacia terapéutica mediante la comparación del tiempo de desaparición de la fiebre, la evolución clínica, los fracasos terapéuticos y las complicaciones. También se evaluó la seguridad de los dos regímenes. Se aplicó la prueba t de student y Chi cuadrado para significación estadística (a=0.05).
