Intellectual, school and occupational performance in patients with idiopathic hypothalamo-pituitary hypothyroidism and primary hypothyroidism.

Intelligence quotient (IQ), school and professional performance were reviewed in 33 patients with idiopathic hypothalamo-pituitary hypothyroidism. Diagnosis was based on low T4 values and clinical signs. All were treated with growth hormone (HGH). In some, hypothyroidism became manifest only after HGH therapy. Birth history revealed breech delivery in 24 and perinatal asphyxia in 15 of them. Thyroid treatment was started at a mean age of 9.8 (range 4-18 years). The mean IQ was 103.4 +/- 16.7 (SD). 9 patients had IQs below 90, 8 of them were born by breech delivery, 3 had severe perinatal asphyxia, one recurrent symptomatic hypoglycemia, and one a micropenis. Of those patients who have reached the respective age, 7 attended college, 3 university, and 9 had skilled professions. Only 7 required special education. For comparison, 52 patients with primary hypothyroidism were studied. Their mean IQ was with 89.3 +/- 18.1 (SD) significantly lower (p < 0.001) than the mean IQ of patients with hypothalamo-pituitary hypothyroidism. The best IQ (96.8 +/- 16.9) was attained when thyroid treatment was started before the age of 4 months, the lowest IQ (78.2 +/- 19.2) was found in the group of patients in whom thyroid substitution was initiated between 5 and 12 months. Patients who were treated after one year of age, had a mean IQ of 90.0 +/- 15.7. This group includes patients with ectopic thyroid glands or acquired hypothyroidism such as Hashimoto's thyroiditis.

Congenital pseudohypoaldosteronism: case report and review. Effect of indomethacin during sodium chloride depletion.

A newborn boy (birth weight 2550 g) presented from the first days of life with poor drinking, moderate vomiting and persistent weight loss. On hospital admission at age 4 weeks, there were severe dehydration, dystrophy and electrolyte disturbances (Na 107, Cl 80, K 5,4 mval/l). The usual causes of salt wasting were excluded, but plasma renin activity, plasma aldosterone and urinary aldosterone-18-glucuronide were markedly increased. DOCA had no salt-retaining effect, but a sodium chloride supplement of 3 g per day improved the clinical condition dramatically and normalized the electrolyte values. With this treatment, plasma renin activity and aldosterone were normal or almost normal beyond the age of 6.5 months, but urinary aldosterone-18-glucuronide remained slightly increased. Considerable augmentation of the plasma renin activity and of urinary aldosterone-18-glucuronide, but no clear salt loss were induced by spironolactone. With salt restriction, there was evidence for marked salt loss. Its progress could be inhibited by administration of indomethacin. Since indomethacin inhibits the synthesis of prostaglandins with saluretic activity, it is probable that the prostaglandins participate in the pathogenesis of the salt wasting in pseudohypoaldosteronism.

Transcutaneous PO2 monitoring in routine management of infants and children with cardiorespiratory problems.

Results are reported concerning the clinical application of the transcutaneous PO2 method (tc PO2 method) according to Huch et al. for monitoring arterial PO2. Thirty long-term continuous tc PO2 recordings were made in 22 ventilated children and infants with cardiorespiratory problems in four different pediatric intensive care units (Zürich, Göttingen, Kassel, and Mainz). These recordings were compared with 132 arterial PO2 determinations made during the same period of time. There was a linear relationship and a close correspondence between arterial PO2 and tc PO2 (r = .94). The continuous recordings have shown that the variability of PO2 is much greater than assumed so far by single blood gas analysis. This fact restricts greatly the value of single samples. Continuous tc PO2 monitoring has proved to be a great help in optimal respirator setting.
