Diagnostico topografico de las hematurias en pacientes pediatricos mediante el porcentaje de hematies dismorficos / Topographic diagnosis of hematurias in pediatric patients by means of a percentage of dimorphic red cells

Se realizo un estudio para fijar el porcentaje de hematies dismorficos que sirva de punto de corte optimo para el diagnostico topografico de las hematurias en pacientes pediatricos. Se utilizaron datos clinicos y de laboratorio de 77 pacientes con hematuria glomerular y 15 con hematuria no glomerular. Mediante una metodologia estadistica se obtuvo 14 por ciento como valor del punto, con lo que se asigna al grupo de las hematurias glomerulares todo paciente que presente una cifra de hematies dismorficos igual o superior. El area bajo la curva ROC (Receiver Operating Characteristic) asociada a este test fue 0,9597, lo que indica una elevada exactitud para la prueba, basntante cercana del valor idal, 1,0 que indica una discriminacion perfecta

Mortalidad infantil en Cuba, 1969-1987 / Infant mortality in Cuba, 1969-1987

The available statitical data indicate that Cuba's infant mortality fell substantially, by roughly 71.5 percent, between 1969 and 1987. Especially great gains were made against late neonatal (7-27 days) and postneonatal (28 days-11 months) mortality, though reduction in early neonatal (0-6 days) mortality was also substantial, amounting to about 54.3 percent. In general the gains were spread fairly evenly amongh the country's provinces, with infant mortality tending to remain higher in the eastern provinces than in the central and western regions. A key factor contributing to these improvements was a policy decision made in the early 1960s that assigned high priority to health sector and lead to major improvements in the health services' organization, quality and coverage. Other changes that seem to have made significant contributions to this trend include improvements in living standards, sanitary and epidemiologic conditions, outpatient médical care, hospital care, and health technology

Algunos aspectos clínicos durante la epidemia de dengue hemorrágico en Cuba / Some clinical aspects of the hemorragic dengue epidemy in Cuba

An outbreak of hemorrhagic dengue fever occurred in Cuba in 1981. Among a population of about 10 milion people, 344.203 persons were affected; 71,3% of these were adults and the remaining were children. Among the latter the disease was more severe. During the peak of the epidemic up to 11.701 cases were reported in one single epidemic up to 11.701 cases were reported in one single day. In this article the organizational aspects of health care delivery durint the epidemics as well as the studies performed in the 2239 patients admited to 3 hospitals of the city of La Habana from June to August 1981 are reported. The most important clinical and laboratory data from sample of 2239 patients under 15 years of age are presented. Some therapeutic aspects, including the experience of the author with the use of interferon in 166 patients, are also discussed
