[Cardiac tamponade in newborn infants with central venous catheter receiving parenteral nutrition]. / Taponamiento cardiaco en neonatos con catéter venoso central y alimentación parenteral.

OBJECTIVE: To alert about an unusual and poorly informed entity, with high mortality. That should be considered in critically ill neonates with central venous catheter and parenteral nutrition, in order to establish early diagnosis and treatment. CASE REPORT: Two neonates, one born at term and the other premature, with central venous catheter and parenteral nutrition. They had sudden unexplained hypotension and signs of decompensation and death secondary to cardiac tamponade. DISCUSSION: Cardiac tamponade secondary to central venous catheter is an unusual entity seldom discussed in the literature. The estimated incidence is 0.3 to 2% with a 74 to 100% mortality. It must be suspected and diagnosed early in order to decrease the mortality.

[Neonatal cardiac rhabdomyoma: case report and clinico-epidemiologic considerations]. / Rabdomioma cardiaco neonatal: informe de un caso y consideraciones clínico-epidemiológicas.

Primary cardiac tumors are very infrequent at all ages; the most frequent in the pediatric age is rhabdomyoma. This tumor is associated with tuberous sclerosis in 37 to 80%, with a frequency of 1 for each 40,000 live newborns. This case is about a newborn, who in the immediate postnatal period presented pansystolic murmur, grade IV cardiomegaly, electrocardiographic changes of biventricular hypertrophy and heart failure. Echocardiogram and magnetic resonance images showed several tumors in the septum and in ventricular walls; histopathology study of the heart, confirmed the diagnosis. The diagnosis of tuberous sclerosis was made clinically (seizures, hypomelanotic macules) and with the image of parenchymal hypodense areas. In our country there is little information about both diseases, that's why we made a review of the incidence, diagnosis, prognosis and treatment.
