We report a case of gas embolism secondary to the use of positive end respriatory pressure in a newborn with ideopathic respiratory syndrome. The anatomicopathological findings lead to the hypothesis that the gas migrates from the broken alveoli through the lymphatic vessels to the venous circulation.

The present paper describes 3 patients with congenital toxoplasmosis. The spinal cord was extremely affected. Differential diagnoses were established with poliomyelitis and neonatal hypoxia. Histopathological studies revealed toxoplasmosis.

The case of a newborn with pathological confirmation of congenital pulmonary lymphangiectasis and hyaline membrane is reported. The lymphagiectasis corresponded to type III, with histological characteristics that make it different from other types of lymphatic dilatation. This association is quite uncommon and should be considered in the differential diagnosis of acute respiratory failure in the newborn period.
A clinical and statistical review of Reye's syndrome is made, reporting the case of a female seven months old infant with disturbances of the digestive tract associated to hepatomegaly, convulsive crises, maculopapular exanthema, extreme hypoglycemia, hyperammoniemia and high blood urea. The post-mortem study showed fine drop diffuse liver steatosis, renal tubuli steatosis, focal steatosis of myocardial fibers, generalized meningoencephalic edema and viral pneumonia. These clinico-pathologic characteristics lead to the diagnosis of Reye's syndrome, an infrequent entity in our milieu judged by national literature.
A study is made of the environmental, etiologic, pathogenic, clinical and anatomical characteristics of the bacterial or parasitic enteral processes which most frequently cause death to the patients. Considerations on the pathogenesis of the complications found at the postmortem studies in children with diarrhea are likewise offered.
In this paper, comparison is made of the clinical with the anatomicopathological diagnosis of DIC. The review of the postmortem studies covered from March 1975 to March 1976 at Hospital de Pediatrïa, C.M.N., and the following were the conclusions: Only in 40 of the cases, the clinical diagnosis of DIC was made. DIC was seen more frequently in the neonatal stage. The anatomicopathological diagnostic criterion is emphasized. Hemorrhages and thromboses predominated in lungs. Paracoagulation tests were not useful.
The case of an infant with Wilson-Mikity syndrome is reported; both the clinical evolution and the radiological findings were characteristic and the diagnosis was confirmed at autopsy. Etiology, differential diagnosis, supportive treatment and care of complications are discussed.
A case of kernicterus in a premature neonate whose highest level of serum indirect bilirubin was 1 mg. is reported. The predisposing factors are discussed and a strong emphasis is placed upon the need for prevention.
