Effectiveness of primiparae and multiparae at soothing their newborn infants.

To examine the effectiveness of new parents at soothing their infants, the authors filmed primiparae (20 mothers, 20 fathers) and, for comparison, multiparae (25 mothers, 25 fathers) during an interaction with their crying 2- to 3-day-old infants. Data were derived from loudness ratings of the infants' distress signals and by measuring the time it took parents to quiet their infants. In addition, specific parental behaviors were coded by microanalysis. From these data, measures of soothing effectiveness and behavioral profiles were derived. Data analyses showed that most primiparae were effective at soothing their infants' cries and that there were no parity effects on measures of soothing effectiveness. However, mothers, regardless of parity, were more effective at quieting their infants than were fathers, and there were significant differences in mothers' and fathers' caregiving behaviors. These data suggest that primiparae are effective at quickly soothing their newborns and that their skill, as measured, does not depend on parenting experience. Moreover, the data point to significant differences in mothers' and fathers' competence at quieting their newborns whether or not they are experienced at parenting.

Inhibition by antibiotic tetracyclines of rat cortical noradrenergic adenylate cyclase and amphetamine-induced hyperactivity.

Two antibiotic tetracyclines, demeclocycline (DMC) and minocycline, share several biochemical and behavioral properties with lithium (Li). DMC inhibited both noradrenaline- and chloradenosine-sensitive cyclic AMP accumulation in rat cerebral cortical slices both in vitro and ex vivo following two weeks of chronic dietary treatment. Minocycline, a lipophilic tetracycline, produced similar results in vitro. Both DMC and minocycline reduced open-field activity levels in rats following acute treatment, four hours prior to testing. Moreover, both drugs inhibited amphetamine-induced hyperactivity in the open field. Chronic treatment with 0.4% and 0.8% dietary DMC for two weeks attenuated amphetamine hyperactivity without affecting baseline activity levels in the open field. Neither DMC nor minocycline attenuated apomorphine-induced stereotypy at doses that attenuated amphetamine hyperactivity, a profile which is similar to that of lithium. Unlike lithium, however, DMC did not reverse reserpine-induced hypoactivity.

Malignant external otitis in an infant.

Ten cases of malignant external otitis in children have been reported hitherto. These are reviewe, and an eleventh case, a three-month-old infant associated with genetic granulocytopenia, is presented. On the grounds of the reported paediatric cases, the erudition in childhood is compared with the more common form in the adult, and is found to be much less linked with diabetes mellitus and to have a far better prognosis, with practically no mortality.

High-performance liquid chromatography of biogenic amines, derivatized with 9-fluorenylmethyl chloroformate.

A procedure was elaborated for the analysis of three biogenic amines posing a considerable health hazard. The method takes advantage of the characteristics of the 9-fluorenylmethyl chloroformate (FMOC) derivative, namely specificity, stability and compatibility for either fluorescence or UV-absorbance detection. The FMOC-tyramine derivative was probably adsorbed to labware when acetone served as the solvent for FMOC. Methanol, substituted for acetone, removed this problem. Excellent linearity was obtained with standard solutions of tyramine, tryptamine and phenylethylamine. Meat samples, spiked with the mentioned amines, also showed good linearity. Perchloric acid was chosen for deproteinization, as potassium perchlorate may be eliminated on neutralization. Histamine failed to react with FMOC or was not detected under the test conditions.

The influence of SCUD missile attacks on the utilization of ambulatory services in a family practice.

The consulting load in a family practice exposed to SCUD missile attacks during the 1991 Gulf War was compared with the equivalent period in 1990. The rate of visits was cut by half, with a relative and absolute increase in psychological consultations, and a decrease in consultations for infectious and respiratory conditions. There were more urgent consultations and fewer planned appointments. It is suggested that the stress of the SCUD missile attacks led to a reduction in consultations for trivial disorders, but an increase in the anxiety level of the population.
