Immunoreactive calcitonin in maternal milk and serum in relation to prolactin and neurotensin.

Maternal milk four days post partum contained immunoreactive calcitonin in concentrations which were 22-89 times higher than those noted in concomitantly sampled maternal sera. Neurotensin-like immunoreactivity was barely detectable in milk. It is suggested that calcitonin may be a prerequisite for the concentration of calcium ions in milk but there is also possibility that it acts locally on the intestinal mucosa.

Sociodemographic differences in the prevalence of self-reported headache in Icelandic school-children.

The study considers the prevalence of headache experiences in a random national sample of 2140 Icelandic 11-12 and 15-16 year-old school-children. The study finds an overall 21.9% prevalence of "at least weekly" headache. The prevalence is significantly higher among younger children and among girls. The gender difference is found to be related to the fact that older boys have a markedly lower prevalence than younger boys. No gender difference is observed in the younger group. Social class interacts with gender, with the gender difference leveling out in the upper class. The frequency of headache experiences correlates with last months use of medication to relieve headache. The high overall prevalence of headache found in this study agrees with earlier findings, and is a matter of concern since little is being done to counter this problem of discomfort among school-children.

Physiologic measures of kangaroo versus incubator care in a tertiary-level nursery.

OBJECTIVE: To determine the safety and feasibility of kangaroo care in a tertiary-level nursery as defined by apnea, bradycardia, and oxygen desaturation. DESIGN: Prospective, long-term, repeated measures with a convenience sample. SETTING: A 20-bed, tertiary-level nursery with approximately 400 admissions a year. PARTICIPANTS: Eight mother-infant pairs. INTERVENTIONS: Researchers compared incubator care with kangaroo care for 4 hours a day, 6 days a week, for 3 weeks. Physiologic variables were monitored daily and recorded continuously on a polygraph for 8 hours each week. MAIN OUTCOME MEASURES: Amount of apnea, bradycardia, and oxygen desaturation. SECONDARY OUTCOME MEASURES: Heart rate, respiratory rate, percent sleep time, and skin temperature. RESULTS: Apnea, bradycardia, oxygen saturation, heart rate, and respiratory rate were similar during both kangaroo (K) and incubator (I) care. The infants experienced a lower percent (mean +/- standard deviation, K versus I) of total sleep (47 +/- 15 versus 64 +/- 19, p < .003) during kangaroo care. The infants' mean +/- standard deviation temperature during the kangaroo care (36.5 degrees C +/- 0.64 degrees C) was lower (p < .03) than that of the control periods before (36.8 degrees C +/- 0.27 degrees C) or after (36.7 degrees C +/- 0.26 degrees C). Percent sleep time and skin temperature were slightly lower during kangaroo care, but the differences were not clinically significant. CONCLUSION: Kangaroo care is safe and feasible for selected mothers and infants in a tertiary-level nursery.
