[Dilated cardiomyopathy in infants and children].

Three cases of dilated cardiomyopathy manifested at 2, 5, and 13 months of age are reported. The clinical, radiographic, electrocardiographic, echocardiographic and angiocardiographic findings are analyzed. The follow up during 11, 14 and 16 years is described. After several years of the onset, 2 patients recovered a normal cardiac function. The third patient required a cardiac transplant when he was 9 years old, and now, after 2 and a half years, he is healthy, without congestive heart failure. Current references about indications of cardiac transplant in this disease are reviewed. We got the following conclusion: In patients with dilated cardiomyopathy, at least in those who begin before 2 years, the indication and the time of the cardiac transplant have to be established by individual valuation of each case, considering the follow up of the risk's criteria, mainly the congestive heart failure.

[Epidemiology of childhood tuberculosis in the Basque Autonomous Community 1980-89. Efficacy of BCG vaccination].

The cases of tuberculosis in the Pediatric Units of the Basque Autonomous Community during the period of 1980-89 were studied. The annual incidence rate in the 0-4 year old age group was 5.8 per 100.00 in Biscay (95% confidence interval: 4.0-7.6), 5.9 (2.3-9.5) in Alava and 16.7 (12.7-20.7) in Guipúzcoa. Out of the 263 registered cases, 55 (21%) corresponded to meningitis and/or miliaria, 194 (74%) to respiratory tuberculosis and 14 (5%) to other clinical forms. Of these cases, the diagnosis in 83 (32%) was based on results from microbiological cultures, in 8 (3%) on histological examinations and in the remaining 172 (65%) on other diagnostic criteria. In 226 cases (86%) no scars were found nor were there any antecedents of BCG vaccination. In 32 patients (12%), there were scars or antecedents of BCG vaccinations and in 5 cases no information was available. The estimated protective effect of the BCG vaccination in the 0-4 year old group was 88% and in the 5-14 year old group 63%. We recommend that the efficiency of the BCG vaccination program be studied in order to assess the need of this program.

[Anomalous origin of the right pulmonary artery from ascending aorta (author's transl)].

One case of anomalous origin of the right pulmonary artery from ascending aorta is reported. The anomalies in the origin of the main pulmonary branches are classified in Type A: Anomalous origin of a pulmonary artery from ascending aorta; Type B: Anomalous origin of a pulmonary artery from the aortic arch through a ductus arteriosus, and Type C: Absence of a pulmonary artery with pulmonary vasculariation through systemic arteries arising from descending aorta. The normal embryology of the 6th. aortic arch and the pulmonary branches and the differents theories postulated about the embryopathogenesis of these malformations are reviewed. The outstanding clinical, hemodynamic, angiocardiographic and surgical features are also discussed.
