ABSTRACT

El probiótico Lactobacillus GG es efectivo en promover una recuperación rápida de la diarrea aguda infantil producida por rotavirus. Hay poca información, sobre el rol de este agente en el efecto sobre la diarrea producida por otros gérmenes, tampoco hay evidencia de su eficacia administrada en la sal de hidratación oral para pscientes con diarrea de diversas causa. Método: Niños de 1 mes a 3 años de edad con enfermedad diarreica aguda fueron enrolados en una investigación doble ciego. Pacientes fueron randomizados y colocados en al grupo A recibiendo sal de hidratación y placebo, y en el grupo recibiendo, el mismo con el agragado de una preparación viva de Lactobacuillus GG. Luego de la hidratación en las 4 ó 6 horas se les ofreció su dieta habitual. Resultados: enrolamos 97 pacientes 52 del grupo A y 45 del grupo B. Duración de la diarrea luego del enrolamiento fue 7 días para el grupo A y 4 días para el grupo B (p<0.005).Para los niños rotavirus positivos la diarrea duró 6 días para el grupo A y 3 días para el grupo B (p<0.005).La diarrea duró más de 10 días, 5 para el grupo A y 1 para el grupo B. Conclusión: Administrar sal de hidratación oral conteniendo Lactobacillus GG a niños con enfermedad diarreica aguda es segura y resulta en duración menor de esta y tiene menos chance de pasar a curso prolongado.

ABSTRACT

We studied microorganisms associated with infant diarrhea in a group of 256 children admitted to a public pediatric hospital in Montevideo, Uruguay. Diagnostic procedures were updated to optimize detection of potential pathogens, which were found in 63.8% of cases, and to be able to define their characteristics down to molecular or antigenic type. Coinfection with two or more agents was detected in more than one-third of positive studies. Escherichia coli enteric virotypes, especially enteropathogenic E. coli (EPEC), were shown to be prevalent. Rotavirus, Cryptosporidium, Campylobacter (mainly Campylobacter jejuni), and Shigella flexneri were also often identified. Enterotoxigenic E. coli, Salmonella, and Giardia lamblia were sporadically recognized. Unusual findings included two enteroinvasive E. coli strains, one Shigella dysenteriae 2 isolate, and a non-O:1 Vibrio cholerae culture. EPEC bacteria and S. flexneri (but not Salmonella) showed unusually frequent antimicrobial resistance, especially towards beta-lactam antibiotics, which is the subject of ongoing work.

ABSTRACT

Sporothrix schenckii antigens were tested with seventy-nine sera from human cases of sporotrichosis for their value in the serological diagnosis of extracutaneous forms of the disease. 55.7% of the sera reacted in the tube agglutination test; 29.1% of them were positive by counter immunoelectrophoresis and only 7.6% reacted in the simple immunodiffusion test. There was a clear correlation between agglutination titers and the respective reactivity of sera by counter immunoelectrophoresis. By immunoelectrophoresis, 2 different anodic precipitin bands were observed between S. schenckii metabolic antigen and anti-Sporothrix hyperimmune animal sera. Since no false positive reactions were found in sera from patients with other mycoses, and considering the simplicity of the antigen preparation, we agree with previous authors that these methods may be useful for the detection of visceral forms of sporotrichosis.

ABSTRACT

En 250 ninos, procedentes en su mayoria del departamento de Montevideo, y que concurren para su asistencia a la Policlinica de Enfermedades Parasitarias del Instituto de Higiene, se hallaron parasitados el 66,4% (con protozoarios, 44,4% y con helmintos, 56%). Se determino el porcentaje de cada parasito hallado, se analizo su distribucion etaria, y los casos de mono, bi y poliparasitismo. Se analizaron los principales motivos de consulta y la sintomatologia predominante en forma global y para cada parasitosis. Se analizo la procedencia de los casos en el departamento de Montevideo
