Intrapartum suctioning of meconium: comparative efficacy of bulb syringe and De Lee catheter.
Intrapartum suctioning of the newborn's pharynx with a De Lee catheter (DL) has reduced the incidence of meconium aspiration syndrome (MAS) in neonates born with meconium staining of the amniotic fluid. However, the bulb syringe (BLB) is used more often for this purpose because of greater technical convenience. In a prospective study, 60 offspring of such deliveries received intrapartum pharyngeal suctioning either by BLB (29 cases) or by DL (31 cases), according to random selection. The presence and amount of meconium in the trachea, incidence and severity of MAS, and mortality from the disease were similar between the two groups. This study suggests that the BLB is as effective as the DL for intrapartum removal of nasopharyngeal meconium in deliveries with meconium staining of the amniotic fluid. Since the BLB is easier to use, less expensive and probably safer, our results suggest that it may be the preferable method.
Absorption and tolerance of lactose in infants recovering from severe diarrhea.
Nineteen infants were challenged during their convalescence from severe diarrhea with a lactose-containing meal. Twenty-four hour intake, pre- and post-challenge breath H2 levels, clinical responses, and growth were measured at approximately biweekly intervals for 3 months beginning 1 month after hospital discharge. Ten lactose-tolerant infants were assigned randomly to receive one of two formulas similar in composition except for carbohydrates: lactose (Group L) (n = 6) and sucrose (Group S) (n = 4). Infants in Group L had greater intakes and growth rates during the initial 15 days of the study. No difference in weight for age z-scores was detected between groups at the end of the observation period. Infants in Group L had higher baseline and peak breath H2 levels indicating greater colonic carbohydrate fermentation than infants in Group S: however, breath H2 levels were not predictive of tolerance to lactose-containing meals. Carbohydrate absorption by infants in Group S appeared to exceed that of infants in Group L. Thus, colonic fermentation of malabsorbed carbohydrate may have prevented diarrhea and allowed acceptable rates of catch-up growth.
Lack of correlation between thyroid size and body growth in an area of endemic goiter.
There is conflicting information in the literature about the relationship between thyroid size and body growth in endemic goiter. This study reports data from highland Bolivia where 408 children were examined for thyroid size, height, weight, head circumference, and academic performance, the latter as measured by teacher evaluation. The presence or size of goiter showed no consistent correlation with height, weight, or head circumference. School performance was significantly correlated with all other variables in boys and not in girls, but there are severe limitations involved in the use of school grades alone for assessment of intelligence. Height and weight were less than for normals in the United States at each age level, but did not differ from those of other Quechuan children in neighboring Peru who were reportedly nongoitrous. Our data support the conclusion that there is no clear relationship between thyroid size and body growth in areas of endemic goiter.
