ABSTRACT
We report 67-year-old woman with a sinus node dysfunction and diffuse conduction system disease, with a history of recurrent paroxysmal atrial fibrillation. She was admitted to the Hospital due to palpitations, dizziness, and vertigo, attributing the symptoms to the rhythm disorder described, for which the implantation of a pacemaker was indicated. With a history of tracheal cancer treated with radio and chemotherapy, and chronic steroid therapy for rheumatoid arthritis, she had an important limitation in vascular access for a conventional pacemaker, so, added to a high risk of infection, a decision was made to implant a leadless pacemaker. We discuss the electrocardiographic and clinical manifestations of sinus node disease, its relationship with oncological treatment and the indication for a permanent pacemaker, highlighting the characteristics of this new modality of artificial cardiac stimulation, for a special type of patients.

An eleven year old boy presented with headaches and dizziness associated to micturition. On radiologic imaging, he was found with a bladder mass. The biochemical work up was suggestive of pheochromocytoma. An OctreoScan (111In-pentreotide) was used to rule out metastatic extension or other extra-adrenal locations of the pheochromocytoma. OctreoScan data correlated well with other radiologic studies, operative findings and with the final diagnosis, validating its use on pediatric patients.

La tuberculosis sigue siendo un importante problema y un tópico de la salud pública de magnitud considerable. La tuberculosis que compromete al sistema nervioso central es un importante y serio compromiso extrapulmonar. El infarto y la hidrocefalia cerebral son complicaciones graves de la meningitis tuberculosa y son de mal pronóstico. Presentamos a un paciente con tuberculosis miliar y compromiso meníngeo que cursa con infartos cerebrales múltiples e hidrocefalia. Él presentó una mala evolución y falleció.
Tuberculosis remains a major global problem and a public health issue of considerable magnitude.Tuberculosis involvement of the central nervous system is an important and serious type of extra pulmonary involvement.Cerebral infarction and hydrocephalus are serious complications of tuberculous meningitis and may worsen the prognosis.We present a patient of milliar tuberculosis and meningeal compromise that course with multiple cerebral infarcts and hydrocephalus. He had a poor outcome.

En el presente estudio se comparo la tecnica de inmunoperoxidasa para la deteccion de citomegalovirus (IPCMV) utilizando anticuerpos monoclonales que reconocen proteinas precoces virales con el metodo convencional de aislamiento viral en fibroblastos humanos. Un total de 150 muestras de orina fueron examinadas encontrando una sensibilidad de un 89.8 por ciento y una especificidad de 91.3 por ciento de la tecnica de IPCMV comparada con el aislamiento viral. Una de las ventajas que presento la IPCMV fue la rapidez con que fueron obtenidos los resultados (48 horas) mientras que el aislamiento viral fue como promedio 14 dias.

Habitualmente el patrón de susceptibilidad a los antibióticos (antibiograma) de los microorganismos se determina a partir de colonias purificadas en un período mínimo de 72 horas utilizando el método clásico de Bauer et al. (1966), basado en la técnica de difusión en gel. Recientemente se ha desarrollado el sistema DIRAMIC-02 para detectar el antibiograma en cuatro horas, empleando las modificaciones conductimétricas del medio de cultivo que genera el crecimiento bacteriano. En el presente trabajo se analizan 28 cepas de microorganismos por el método rápido, estableciéndose el coeficiente de correspondencia con el método clásico
