TASK DEFINITION: Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.
PROBLEM: Abstract: The influence of various medium supplements on Sertoli cell (Sc) monolayer permeability to [3H]inulin and polarized secretion of transferrin (Trf) and androgen-binding protein (ABP) was investigated in a two-compartment culture chamber. Sc from 14- and 18-day-old rats were maintained for 13 days in one of the following media: Modified Eagle's Medium-Ham's F-12 (DFM), DFM plus insulin, epidermal growth factor, progesterone, hydrocortisone, and vitamins A and E (6F), 6F plus testosterone (7F), 7F plus FSH (8F), 6F plus 2% fetal bovine serum (6F2S), 6F plus 5% fetal bovine serum (6F5S). The monolayer permeability to [3H]inulin decreased rapidly during the initial 3-5 days of culture for the Sc isolated from 18- and 14-day old animals, then remained stable in all media except DFM. Morphological examination revealed the presence of tight junctions between neighbouring Sc in both age groups, indicating their de novo formation. Secretion of Trf was lowest in DFM and steadily declined. In all other media, Trf secretion peaked on day 5 and remained relatively constant after day 7. Medium 7F only slightly and inconsistently increased the secretion, whereas 8F was always highly stimulatory compared to 6F. Supplementation of 6F with serum resulted in the greatest Trf secretion. In the case of ABP, three different secretion patterns were noted depending on the medium composition; secretion was greatest in the presence of 5% fetal bovine serum. The medium supplements also differentially affected the polarity of Trf and ABP secretion. The ratio of Trf secreted to the outer and inner compartments (OC/IC) was approximately 2.0 in DFM and was not influenced by supplements in 6F, 7F, and 8F. However, in serum-containing media, the OC/IC ratio gradually increased with time to about 5.0 on day 13. The average OC/IC ratio of ABP was 1.7 in DFM and, in contrast to Trf, declined to 0.7 in other serum-free media. Serum supplementation reversed and increased the ABP ratio to about 6.0 on day 13. These data indicate that Sc grown on permeable supports form confluent monolayers that limit the diffusion of macromolecules, most likely due to the formation of tight junctions. The monolayer permeability as well as the total and polarized secretion of Trf and ABP are differentially regulated by hormones and serum factors.

SOLUTION: Yes

PROBLEM: Abstract: The effects of parental smoking on IgE and IgD levels in cord serum and subsequent infant allergy were investigated in an unselected series of 186 European newborn infants. Maternal smoking caused a significant rise in both IgE (p less than 0.05) and IgD (p less than 0.05), a finding that was most apparent in newborn infants with a negative biparental history of allergy (p less than 0.025 and p = 0.005, respectively). Furthermore, newborn infants of nonallergic parents had a more than threefold (p less than 0.01) higher incidence of elevated cord IgE (greater than or equal to 1.20 IU/ml) and a fourfold (p = 0.005) higher risk of developing definite or probable atopic disease before 18 months of age if the mother smoked than if she did not. Paternal smoking did not influence, in whatever the subgroup, cord IgE or subsequent infant allergy but increased cord IgD (p less than 0.001) among newborn infants with a negative family history even after controlling for maternal smoking (p less than 0.04). These results suggest that parental smoking in some way affects the fetal immune system, probably via substances in tobacco smoke. Maternal smoking in particular appears to exert a pronounced effect on the IgE system already in fetal life, predisposing even "low-risk" infants to subsequent sensitization, probably in synergy with a later acquired mucosal damage that would facilitate penetration of foreign matter. Pregnant women and mothers should be encouraged to try and give up smoking that might help to prevent allergic disease in their infants.

PROBLEM: Abstract: A case history of a seven-month-old girl arriving at the emergency department in cardiac arrest from an inhalation injury without venous access is described. The patient was resuscitated with endotracheal administration of epinephrine and atropine. A review of the literature of endotracheal administration of medications in pediatrics subsequently follows.
