To determine whether body weight during the first 2 weeks of life in preterm infants weighing less than 1500 gm reflects nutritional status or fluid balance, we studied total body water (TBW) (deuterium oxide dilution), extracellular volume (sucrose dilution), and plasma volume (Evans blue dilution), together with intake-output studies of nitrogen, fluid,(More)
BACKGROUND Anemia of prematurity is characterized by low reticulocyte counts and inadequate erythropoietin response, for which many very-low-birth-weight infants receive multiple blood transfusions. We investigated whether early treatment of such infants with recombinant human erythropoietin would reduce their need for transfusions. METHODS We performed a(More)
The effects of blood transfusion on cardiac output and blood pressure are variable, but resting peripheral blood flow (RPBF) may be a sensitive indicator of changes in blood volume. The purpose of this investigation was to study the effects of red cell transfusion on blood volume (Evans blue), blood pressure, RPBF in the leg (strain-gauge plethysmography)(More)
BACKGROUND Although nonoliguric hyperkalemia of the premature infant is a common problem, in many hospitals it is not observed. It is characterized by an excessive increase in serum potassium concentration (serum-[K (+)]) at 24 hours after birth. Recently, salbutamol has been recommended to treat hyperkalemia. There are no controlled trials in premature(More)
A case of diffuse mesangial sclerosis (DMS) associated with a number of undescribed congenital anomalies is reported. The occurrence of additional anomalies, especially ocular anomalies, is a common finding in DMS. However, neither megalocornea, Dandy-Walker malformation, postaxial hexadactyly, rocker-bottom feet, nor atrial septal defect, as observed in(More)
OBJECTIVE This prospective study reports on the prevalence of hearing impairment in an at-risk neonatal intensive care unit (NICU) population. DESIGN From 1990 to 1998, 1062 neonates were screened with the use of transitory evoked otoacoustic emissions (TEOAE) and brainstem evoked response audiometry (BERA). RESULTS 934 infants passed the primary screen(More)
Xerocytosis is a rare, autosomal dominant-inherited membrane defect of the erythrocytes with an increased osmotic resistance and a reduced intracellular potassium concentration. It was first described by Glader in 1974.' Affected individuals show mild anemia and reticulocytosis. About 20 cases have thus far been described in the world literature. In most(More)
