Alcohol and the adolescent trauma population

Trauma is the leading killer of children and adolescents between 1 and 21 years of age. Alcohol-impaired driving represents the single greatest cause of mortality and morbidity of children over the age of 6. We retrospectively reviewed 878 consecutive adolescent (age range, 16 to 20 years) trauma admissions for blood alcohol concentration (BAC). Four hundred sixty-seven patients had BAC drawn, 258 were BAC-negative (group I), 209 (48%) were BAC-positive (group II). The adolescent drinkers were then compared with a group of 748 adult drinkers (group III). Groups I and II differ in sex, age, time of day of the accident, Injury Severity Score, Glasgow Coma Score, and Revised Trauma Score, whereas group II and III differ by type of accident, type of injury, socioeconomic factors (bad debt), time of day of the injury, and BAC. There were no significant differences in TRISS predicted survival, actual survival, nor mean length of stay. We conclude that (1) alcohol is a significant contributor to injury during adolescence, and (2) adolescent drinkers differ from adult drinkers in their habits, demographics, and socioeconomic status. These socioeconomic differences have implications for the access to and cost-effectiveness of interventions.     

Anesthetic considerations of an infant with Beckwith-Wiedemann syndrome

The case of a 3-day-old infant with Beckwith-Wiedemann syndrome who required anesthetic care during closure of an abdominal wall defect is presented. Beckwith-Wiedemann syndrome comprises a constellation of clinical features, including macroglossia, macrosomia, omphalocele, visceromegaly, mild microcephaly, facial nevus flammeus, horizontal earlobe creases, and renal medullary dysplasia. Due to the high rate of omphalocele in this syndrome, anesthetic care is frequently required during the neonatal period. Many of these infants (greater than 50%) are born prematurely. Therefore, their anesthetic care may be further complicated by associated diseases of prematurity, such as hyaline membrane disease. Additional anesthetic implications of this syndrome relate to the occurrence and management of hypoglycemia and polycythemia. Careful intraoperative management of glucose homeostasis is particularly important, since eventual neurologic outcome and intelligence will be normal provided prolonged neonatal hypoglycemia is avoided. Preoperative evaluation of the cardiac and genitourinary system, including echocardiography and renal ultrasound, are recommended because of the frequent occurrence of associated anomalies with omphalocele.     

Selected predictors of health promotion counseling by three groups of allied health professionals

Three groups of allied health professionals, including dental hygienists, dietitians, and certified nurse-midwives, were surveyed to determine current practice, beliefs, and attitudes regarding health promotion and disease prevention. The study aimed to explore the power of selected variables drawn from social learning theory in predicting self-reported level of counseling. We conducted separate analyses for 10 areas of health promotion and disease prevention: high blood pressure, smoking, lack of exercise, overweight, high-fat diet, alcohol abuse, illicit drug use, stress, isolation and loneliness, and nonuse of safety belts. The predictor variables were respondents' professional group membership, confidence that they possess appropriate skills and knowledge to counsel patients (self-efficacy), belief that patients will follow through on recommendations (adherence expectation), and belief that reduction of risk will improve patients' health status (expectation of health impact). The level of counseling activity varied markedly across the risk areas, with blood pressure and weight receiving the most emphasis on average and isolation and loneliness and nonuse of safety belts receiving markedly less attention. There also was variation across the professional groups. Certified nurse-midwives had higher mean counseling scores in all topics except those related to diet, where the dietitians' mean scores were approximately the same. Of all the areas about which counseling might be increased, use of safety belts stands out as having the lowest reported prevalence, the least complexity in terms of implementation, and the most relevance to at least two of the professional groups. These findings suggest the importance of skills training, including the provision of actual or simulated counseling experience and modeling by others in the same professional group.(ABSTRACT TRUNCATED AT 250 WORDS)     

An alternative technique for laparoscopic cholangiography

The current methods utilized for laparoscopic cholangiography involve cystic duct cannulation and present practical difficulties and potential hazards. An alternative method for intraoperative cholangiography is described which is easy, quick, and safe. The Kumar clamp (a gift from Sabi Kumar, M.D.) is placed across the infundibulum. A 23-gauge sclerotherapy needle is introduced through a side port in the clamp and directed into the infundibulum. The cholangiogram is obtained prior to any dissection in the triangle of Calot, thereby avoiding iatrogenic common bile duct injuries due to misidentification of the cystic duct or anomalous anatomy. To date no pathology has been missed and no complications have resulted from this technique.     

An electrophysiological investigation of the relationship between conceptual fluency and familiarity

Brain potentials associated with the manipulation of conceptual fluency in a recognition memory paradigm were recorded. Enhanced fluency was associated with attenuation of the N400 and an increased rate of subjects' endorsing both studied and non-studied items as having been studied ("old" responses) in the recognition test. Differences were also found in latencies previously associated with post-retrieval processing, such that in the setting of enhanced fluency (1) non-studied items were associated with a positive wave from 800 to 1600 ms and (2) items endorsed as "new" were more positive than those endorsed as "old" from 1200 to 1600 ms. The effects on the N400 may be related to the impact of fluency on familiarity, whereas later processing may be involved in the attribution of fluency to prior experience.
