[Analysis of urine in the child without renal disease and with fever].
The study comprised 24 patients with ages between 5 months and 13 years and fever from different extrarenal infectious diseases. Seventy-nine samples of urine were taken to determine proteins, glucose, ketone, hemoglobine and study of the urinary sediment. Electrophoresis of proteins was practiced to samples with higher content of them. Considering a normal rate of protein the figure above 4 mg/hr/m2, 70% of the patients and 39% of samples showed abnormality with figures up to 52 mg/hr/m2, or 1,259 mg/l. All of them excreted albumin and alphaglobulins; 15, betaglobulins and 4, gammaglobulins. No relationship was found between the amount or type of protein excreted and the degree of fever, age of the patient or type of disease. Thirty-seven per cent of the patients showed ketonuria, 29% erythrocyturia, 21% hemoglobinuria, 16% glycosuria, 12% cylindruria, and 8% leukocyturia. The duration of abnormalities lasted from 1 to 4 days and the magnitude was usually mild, having obtained in all of the cases, a normal sample of urine and a negative urine culture before discharge of the patient. Findings with other studies are compared and the pathogenesis of abnormalities is discussed.
