Effects of neonatal stunting on the development of rats: early and late effects of neonatal cortisone on physical growth and skeletal maturation.

Cortisone acetate, 1.25 mg, was given im to each pup of eight eight-pup litters; saline was given to each pup of eight litters. At 21 days body weight, stem length, and length of long bones was less in the treated animals (P less than 0.001). The number of ossification centers was greater in the treated animals (P less than 0.05). Brain weight was less in the treated animals (P less than 0.001). For 84-day-old animals body weight (P less than 0.02) and length of most long bones (P less than 0.05) were less in the treated females. Body weight (P less than 0.01), stem length (P less than 0.01) and some bones (P less than 0.02) were smaller in the treated males. There was no difference in the number of epiphyseal fusions. The brains of the treated males weighed less than those of the controls (P less than 0.01). The effect on linear growth is in conformity with observations in children but the accelerated skeletal maturation was unexpected. The effect on skeletal maturation was less persistent than that on bone length.

[Neonatal screening for congenital adrenal hyperplasia due to 21-hydroxylase deficiency. 4. Development of enzyme-linked immunosorbent assay for dried blood cortisol and its application to neonatal screening for congenital adrenal hyperplasia due to 21-hydroxylase deficiency].

An enzyme-linked immunosorbent assay (ELISA) for Cortisol in dried blood collected on filter paper has been developed. The ELISA method is very simple and rapid and has sensitivity, accuracy and precision. The detection limit of the ELISA is 10 ng/ml blood. The intra- and interassay coefficients of variation are 11.5-13.5% and 15.7-16.7, respectively. Using the ELISA for Cortisol and 17-hydroxyprogesterone (17-OHP) previously reported, dried blood from normal newborns including premature infants (n = 1583) and 21-hydroxylase deficiency (21-OHD) patient (n = 9) were analyzed. 17-OHP, Cortisol and 17-OHP/Cortisol ratio of normal newborns are 12.5 +/- 7.5 ng/ml (1.0-140 ng/ml), 89.0 +/- 64.3 ng/ml (10-1580 ng/ml) and 0.16 +/- 0.08 (0.01-0.86), respectively. In 21-OHD patients, 17-OHP is 109-1361 ng/ml, Cortisol is 35.1-146.7 ng/ml and 17-OHP/cortisol ratio is 1.84-12.2. It made recall rate less to measure Cortisol in addition to 17-OHP and to take 17-OHP/Cortisol ratio. Therefore, additional measurement of Cortisol to the primary 17-OHP screening test is advantaged in differentiating the normal newborns from the 21-OHD patients.

Systemic response to mydriatic eyedrops in neonates: mydriatics in neonates.

During routine dilation of 48 newborns, systemic responses and pupil dilation were monitored. Both 10 percent aqueous and viscous phenylephrine caused blanching around the eyes and produced considerable rise in blood pressure. Dilatation average 4.7 mm. In a double blind study, a 2.5 percent solution caused no skin blanching and no change in pressure or heart rate. Average dilation was 4.5 mm. No blood pressure changes were observed with either one percent cyclopentolate or one percent tropicamide. Average dilatations were 5.0 mm and 5.3 mm respectively. The above agents, used individually for a total dosage of three drops in each eye did not provide adequate dilation for a thorough funduscopic examination. Our protocol at United Hospitals Medical Center is a safe combination of drugs and provides excellent dilatation averaging greater th an 7 mm. No skin blanching or change in heart rate was observed.
