Neonatal fat digestion and lingual lipase.

Lingual lipase (LL) activity, pH, and products of fat hydrolysis were determined in gastric aspirates from preterm infants who received formula milk feeds by a nasogastric tube. In 1-hourly (n = 9), 2-hourly (n = 8) and 3-hourly (n = 9) fed infants LL activity increased to reach its maximum value at 60, 90, and 120 min respectively after the feeds, and gastric pH levels fell from about 6.0 to less than 3.5. There was a reduction in triglyceride content to 50% of the initial value, measured immediately after a feed, and the products of hydrolysis were mainly diglycerides and FFA. In a subsequent study 3-hourly fed infants (n = 8) had a tube feed followed by a bottle feed, and then a bottle feed followed by a tube feed on successive days (cross-over). The LL activity observed after a bottle feed (mean maximal value 23.8 mumol FFA/ml/h) was significantly higher than after a tube feed (19.1 mumol FFA/ml/h). It is suggested that substantial triglyceride hydrolysis takes place in the stomach due to lingual lipase, and sucking seems to enhance enzyme production.

Lymphangiography as an aid in staging bladder carcinoma.

Eighty patients with histologically proven carcinoma of the urinary bladder had pedal lymphangiography as part of their assessment for metastatic disease. Results were correlated with surgical findings within three months of the lymphangiographic interpretation in 49 patients. There were no false-positive lymphangiograms, and only five (10%) false-negative readings were recorded. The finding of positive lymphangiograms in 9% of patients with stage B disease, 16% of patients with stage C disease, and 57% of patients with a fixation of the tumor to the pelvic or abdominal wall emphasizes the value of the procedure in limiting unnecessary surgical exploration.

Age and emotion of an offender as determinants of adult punitive reactions.

Male and female college students were shown videotapes of supposed male offenders describing the details of thefts they had committed. Videotaped sequences were varied so that offenders were 9 to 10 years old or of college age. Also, actors varied in their mode of emotional self-presentation. Comparisons of punishments suggested by subjects indicated that joyful actors received the highest level of punishment while distressed offenders received the lowest level of suggested punishment. It was also found that the emotions of children exerted a greater persuasive effect on subjects' ratings than did the emotions of adults although the pattern of results was similar across ages. These results were discussed as demonstrating that the age and emotion of an offender can exert considerable influence on the attribution of blame made by a disciplinarian.

Urographic manifestations of metastatic melanoma.

Urinary tract involvement with metastatic malignant melanoma occurs much more commonly than generally thought. It is usually part of a disseminated process with a poor life expectancy. The renal parenchyma is the most common site affected, although this is infrequently detected roentgenographically. Urothelial involvement of the renal pelves, ureters, and bladder manifests as single or multiple filling defects at pyelography. This appearance of metastatic melanoma of the urinary tract has not been previously described in the roentgenologic literature. Recognition is important to prevent unnecessary intervention and to guide palliative treatment.

Effect of nursing caries on body weight in a pediatric population.

A review of anesthesia and sedation records of children with nursing caries was undertaken. The weights of these 115 children with otherwise noncontributory medical histories were compared to subjects matched for age, gender, race, and socioeconomic status. Nursing caries children were treated using either sedation or general anesthesia and received treatment for at least one pulpally involved tooth. Comparison subjects had no gross carious lesions. The average age for both the comparison and test groups was 3.2 years (SD = 1.01 and 0.98, respectively). While comparison patients weighed 16.2 +/- 3.08 kg, patients with nursing caries weighed only 15.2 +/- 2.66 kg. This difference was statistically significant (P < 0.005). Of the nursing caries patients, 8.7% weighed less than 80% of their ideal weight, compared with only 1.7% of the comparison patients (P < 0.02). Of nursing caries children, 19.1% were in the 10th percentile or less for weight, compared with only 7.0% of comparison subjects (P < 0.01). The mean age of "low weight" patients with nursing caries was significantly greater than for patients at or above their ideal weights, indicating that progression of nursing caries may affect growth adversely.
