ABSTRACT
Introducción: La infección producida por Mycobacterium bovis es una forma excepcional de tuberculosis humana en los países desarrollados. En la actualidad, se consideran como agentes etiológicos de la tuberculosis humana M. tuberculosis, M. bovis, M. africanum y el bacilo de Calmette-Guerin. Caso clínico: Niño de 14 años contagiado de tuberculosis a través de la herida producida por el asta de una vaca brava y que afecta a los ganglios próximos a dicha herida. Discusión: En la mayoría de los países con condiciones sanitarias avanzadas, la tuberculosis humana producida por M. bovis es escasa o casi inexistente, gracias al control de los animales y a la pasteurización de la leche de vaca. M. bovis es una de las especies del complejo M. tuberculosis y es el agente causal de la tuberculosis bovina, aunque cuenta con gran cantidad de especies hospedadoras diferentes, entre ellas, la humana, sin olvidar el ganado bovino infectado, ganado porcino, tejones y otros mamíferos (AU)

Los tumores malignos de tejidos blandos en la infancia y adolescencia, exceptuando los linfomas, son muy infrecuentes y, dentro de ellos, el denominado sarcoma sinovíal representa un porcentaje muy bajo. En este trabajo aportamos el caso de un adolescente afectado por un tumor de esta estirpe localizado en un pie (AU)

Diarrheic processes from an infectious origin constitute a frequent pathology during childhood. We have analyzed, from a epidemiological point of view, a series of 117 children diagnosed as having diarrhea and having stool cultures bacteriologically positive for Salmonella. Special reference has been made to the epidemiological chain of this infection. Of the patients studied, 68 (58.2%) were boys and 49 (41.8%) were girls. Their ages ranged between 1 month and 14 years. An epidemiological environment was recognized in 34.1% of the cases. The most frequent serotype was Salmonella Enteritidis (72.6%).

Infectious diarrhoea are common causes of morbility in children. Although viral agents are responsible for the majority of cases of acute diarrhoea during infancy, bacterial infections are also well recognized as causes of them. 256 patients with diarrhoea due to a bacterial pathogen were studied to determine the importance of different epidemiologic factors. The study group comprised 151 boys (59%) and 105 girls (41%) aged between first month and 14 years. Family history of acute diarrhoea was found in 15% of children. 63,7% of them were hospitalized by the severity of clinical features. 32% of cases were detected in summer. Salmonella entérica was isolated in 45% of stool samples and Campylobacter spp in 33,2%. Clinical evolution of diarrhoea differentiated the patients into three groups: acute diarrhoea (95,7%), prolonged diarrhoea (3,1%) and chronic diarrhoea (1,1%).

Cortical auditory evoked potentials (CAEP) were recorded from scalp electrodes in 47 patients, who survived to bacterial meningitis in their childhood. CAEP were obtained from 1 month to 8 years after recovering from acute disease. Neisseria meningitidis was the microorganism more frequently isolated from CSF (43.5%). Exclusively abnormal values in amplitude of CAEP were registered in 15 cases (32%), mainly at the lower tones explored; 14 of them were subjected to conventional audiometric test, which demonstrated unilateral hearing loss only in 2. No alterations in the latency of P2 wave were seen. We recommend to include CAEP in search of hearing disorders in younger children after recovering from meningitis, since they can detect lesions in cortical-subcortical auditory tracts, which otherwise could go unnoticed.

Intravenous brain angioscintigraphy in combination with immediate static scan are very useful as a complement to the clinical and electroencephalographic data in diagnosis of brain death. Confusion in the differentiation of extracerebral from intracerebral flow on the dynamic radionuclide angiogram can be accomplished by identifying presence or absence of uptake in cerebral sinuses. Authors consider that the radionuclide study should be carried out in posterior view. Exploration is safe, quick to perform and easy to interpret and it enables to distinguish brain death from comas due to drug intoxication.
