[Prenatal diagnosis of bronchopulmonary sequestration at the 26th week of gestation: report of a case]. / Consideraciones del diagnóstico prenatal del secuestro broncopulmonar a las 26 semanas de gestación: informe de un caso.

A case report of a 18 years-old women on her first pregnancy, (26 weeks). US detected a live fetus with pulmonary sequestration diagnosis. On week 39 vaginal delivery occurred. A live newborn, Apgar 7-8 and Silverman 4-4 (one minute and five minutes respectively) was obtained. When diagnoses was confirmed, a surgical resection was performed (five days) and the child died at day-15 due to nosocomial sepsis. This case shows the convenience of prenatal diagnosis for management decisions.

[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.

[Perinatal mortality in San Luis Postosí, 1988]. / Mortalidad perinatal en San Luis Potosí, 1988.

Through participation of ten hospital institutions in the city of San Luis Potosí, which systematically take care of newborns, the present collaborative study was performed; this includes all births during the period from january 1st. to december 31st., 1988. The births taken place at home and other sites such as the "Hospital Materno Infantil" during the last six months, were excluded from the study; they accounted approximately 10%. We registered 17,092 births including 204 mortinates. Based on the upper data, the following chart is given, stating weight as well as gestation rates. Precocious fetal mortality (500 to 999 g)--391.30 by thousand; Precocious fetal mortality (20 to 27 weeks)--140.40 by thousand; Late fetal mortality (1,000 g or more)--9.25 by thousand; Late fetal mortality (28 weeks or more)--9.89 by thousand; Hebdomadal mortality (500 to 999 g)--571.40 by thousand; Hebdomadal mortality (20 to 27 weeks)--159.40 by thousand; Hebdomadal mortality (1,000 g or more)--11.96 by thousand; Hebdomadal mortality (28 weeks or more)--12.62 by thousand; Perinatal mortality (1,000 g or more)--21.10 by thousand; Perinatal mortality (28 weeks or more)--22.38 by thousand. The IMSS sent for registration 8,710 births which accounted 51% of the total. Their data revealed the highest values in all rates. In precocious fetal mortality (products between 20 and 27 weeks), the rate value was 543.9 against 140.4 globally counted. Hebdomadal mortality for this 20 to 27 weeks group showed 730.8 against 159.4 globally reported. In 199 out the 204 mortinates, cause of death was registered; 49.7% of these causes was reported as placental circulation insufficiency and 17.1% as major congenital abnormalities.(ABSTRACT TRUNCATED AT 250 WORDS)
