Effects of oral alcohol on superior mesenteric artery blood flow in normal man, horizontal and tilted.
1. The cardiovascular effects of oral alcohol (0.5 g/kg body weight diluted to 300 ml in sugar-free orange juice) were compared with those of placebo in 10 normal subjects. Measurements were made while the subjects were supine and horizontal for 45 min and after 10 min of 45 degrees head-up tilt. 2. After alcohol, plasma alcohol levels rose from 1.9 +/- 1.3 to 61.6 +/- 6.5 mg/100 ml. After placebo, plasma alcohol levels did not increase. After alcohol and placebo, supine blood pressure was unchanged; heart rate, both supine and during tilt, rose after alcohol only. 3. After alcohol, superior mesenteric artery and digital skin blood flow increased and calculated vascular resistances fell. There was no change after placebo. 4. Forearm blood flow, forearm vascular resistance and cardiac index did not change in either phase, except for a fall in cardiac index during tilt but only after alcohol. 5. In conclusion, the acute ingestion of 0.5 g of alcohol/kg body weight in normal subjects raised heart rate and actively dilated the superior mesenteric artery and digital skin vessels. There was no effect on blood pressure, cardiac output and skeletal muscle vascular tone. During head-up tilt after alcohol, there was a tendency for blood pressure to fall with a compensatory rise in heart rate.
Munchausen syndrome by proxy: a survey of professionals' knowledge.
This study examined professionals' knowledge of a relatively rare form of child abuse, Munchausen syndrome by proxy (MSBP). Eighty-six professionals representing hospital or other medical settings, community services programs, the state children's service agency, and various law enforcement agencies were surveyed. Results indicated that professionals employed in medical or hospital settings were three times more likely to have heard of the syndrome than those employed by community service agencies. Journal articles and colleagues were the most popular sources of information pertaining to MSBP. Respondents identified 77 possible cases of MSBP in their caseloads over the past year. Findings suggest the need for educating community professionals as well as the possibility that the incidence of MSBP has been grossly underestimated. Implications for future research and preventive efforts are discussed.

Do pediatric nurse practitioners recognize sexual abuse?
INTRODUCTION: This study was undertaken to describe pediatric nurse practitioners' (PNPs') knowledge of genital anatomy and their ability to recognize sexual abuse. METHOD: A 33-item questionnaire developed by Ladson, Johnson, and Doty (1987) was revised, and PNPs were asked questions about demographics, their knowledge of normal and abnormal prepubescent genital anatomy, and their recognition of the association between sexually transmitted diseases and sexual abuse in prepubescent girls. The questionnaire was mailed to 213 PNPs within the state of Ohio, all of whom were members of the Ohio Chapter of NAPNAP. RESULTS: No statistically significant correlation was noted between any demographic characteristics and correct responses to questionnaire items. Two anatomical parts--hymen and vaginal opening--were correctly identified by less than 60% of the participants. Only 67.1% of the PNPs stated that a child can have a normal genital examination after penile penetration of the vagina. CONCLUSIONS: PNPs need to increase their knowledge of normal prepubescent genital anatomy and physical findings of sexual abuse and report these findings if abuse is suspected.
