Thyrotropin, prolactin and growth hormone response to synthetic thyrotropin-releasing hormone in newborn infants.

The effects of 50 microgram synthetic thyrotropin-releasing hormone (TRH) intravenously on thyrotropin (TSH), prolactin (PRL) and growth hormone (GH) levels were studied in 8 normal male newborns during the first hours of life. Mean plasma GH concentrations were similar to baseline values during the period of study; on the contrary, plasma PRL and TSH values increased in all infants after TRH administration. These data demonstrate a normal pituitary reserve of PRL and TSH in the early period of human life.

Agar in control of hyperbilirubinemia of full-term newborn infants with erythrocyte G-6-PD deficiency.

40 full-term newborn infants with erythrocyte glucose-6-phosphate dehydrogenase (G-6-PD) deficiency were used for a study concerning the effectiveness of agar per os in preventing severe hyperbilirubinemia. 20 randomly selected neonates were given agar (1 g/kg/day) orally in 4 daily doses from their 1st to their 5th day of life. 20 infants were not treated and served as controls. Three exchange transfusions were performed in the experimental as well as in the control group. According to these results, agar does not seem to be effective in preventing severe hyperbilirubinemia, which frequently occurs in newborn infants with erythrocyte G-6-PD deficiency.

Effect of LRH on gonadotropin secretion in newborn male infants.

The concentrations of LH and FSH were measured in eight male newborn babies, aged 4-6 h, before and after the administration of 25 micrograms synthetic LHR. A comparison was performed with six control newborns receiving normal saline. Both LH and FSH rose significantly in all subjects after LHR administration. Their values were significantly higher than those observed during the control study. These data demonstrate sensitivity of the pituitary gonadotropes to synthetic LHR and a pubertal-type response to LH in the early hours of human life.

Dynamic evaluation of prolactin secretion during the early hours of life in human newborns.

PRL secretion was evaluated in 30 human newborns during the early hours of life. Both levodopa and pyridoxine administration failed to suppress PRL release in all subjects. Synthetic TRH elicited a constant, prompt increase in PRL levels. No significant changes were observed after somatostatin injections. These results demonstrate normal pituitary PRL reserve in newborns. The failure to respond to levodopa and pyridoxine administration might reflect partial immaturity of the pituitary dopaminergic receptors.

Elevated gastric lesions: virtual gastroscopy.

With the development of multidetector computed tomography and the improvement in the capabilities of workstations, the use of high-quality three-dimensional reconstructions and virtual images can be applied to organs other than the colon such as the stomach. As a noninvasive technique, virtual gastroscopy represents an alternative to conventional endoscopy for the detection of elevated lesions. Findings of this technique are illustrated.

[Vaccination against measles].

The present status of measles vaccination in Italy using live further attenuated measles virus is examined in detail. Data are also reported of a clinico-statistical study on the frequency of side-effects with measles vaccination as well as of antibody response to it in 1542 children subdivided into different groups according to age and virus strain used (Schwarz or Moraten).
