[Evoked auditive potentials in hydrocephalic neonates].

Auditory evoked potentials were measured in 10 newborn babies who had hydrocephalus of different etiologies. Eight showed abnormal results in the initial study with the most frequent anomaly being an absence of all waves that was unrelated to the postconceptional age. The results changed with time in one case who, after 10 weeks, showed the appearance of waves. Furthermore, in two cases the insertion of a ventriculo-peritoneal shunt provoked striking changes consisting of the appearance and normalization of the waves I, III and V latencies.

[Maturation of auditory evoked potentials in preterm newborns].

Auditory evoked potentials were recorded in 25 babies with postconceptional age between 32 and 37 weeks without any risk factors for brainstem dysfunction. Waves I, III and V were constant while waves II and IV appeared more frequently with increasing gestation. The latency of waves I and III did not vary significantly in the period investigated while waves V significantly decreased its latency from 7.69 m in week 32 to 7.06 m in week 37 (p less than 0.01). I-V interwave interval or brainstem conduction time decreased from 5.59 m to 4.96 m over this period (p less than 0.01).

[Urinary excretion of calcium, magnesium, uric acid and oxalic acid in normal children].

A group of normal children with a free diet was studied. Their first morning urine (n = 176) and their 24-hour-urine (n = 64) was collected, valuing the calciuria, magnesiuria, uricosuria and oxaluria, establishing their relationship with a dietetic survey. Ca/Cr rate value was 0.13 +/- 0.7 mg/mg in the morning urine, and 0.12 +/- 0.06 mg/mg in the 24-hour-urine. Calciuria (mg/kg/day) was 2.46 +/- 1.45, higher to that noticed by other authors. Prevalence of hypercalciuria was 7.8%. We haven't noticed any correlation between the calciuria (mg/kg/day) and the consumption of proteins and carbohydrates. A positive correlation was found between Ca/Cr and Na/Cr rate, together with high natriuria (3.87 +/- 1.35 mEq/kg/day); these findings could justify the elevated calciuria in the children studied. Mean values of magnesium and uric acid were 0.04 +/- 0.02 and 0.30 +/- 0.08 mg/100 ml FG, respectively and the oxaluria was 34.51 +/- 16.35 mg/day/1.73 m2.
