Right ventricular dilated cardiomyopathy.

Fourteen patients with predominantly right sided dilated cardiomyopathy were studied, of whom five died suddenly. The condition is characterised by male preponderance, syncope, ventricular tachycardia, which typically has a left bundle branch block pattern on the surface electrocardiogram, and right heart failure. The diagnosis should be considered in patients presenting with otherwise unexplained ventricular tachycardia or syncope; the diagnosis may be readily missed because of the nonspecific nature or absence of signs.     

Pathways of influence on fifth and eighth graders' reports about having had sexual intercourse

The purposes of this study were to explore the differences between fifth and eighth graders' self-reports of having initiated sexual intercourse and the factors related to their early sexual debuts. The urban sample consisted of African American and white fifth (n = 59) and eighth (n = 169) graders. Among fifth graders 46% and among eighth graders 55% reported they had initiated sexual intercourse. Sexual intercourse was more common than other risk behaviors such as cigarette smoking and drinking. The multivariate analyses indicated that the influences on the early initiation of sexual intercourse were complex. Specifically, gender, use of alcohol, costs (i.e., perceptions of negative consequences), and personal norms (i.e., beliefs about when to initiate sexual intercourse) had no direct influence on having initiated sexual intercourse, but indirectly affected the initiation of sexual intercourse through the frequency of other intimate behaviors. The findings are discussed in terms of gender-specific socialization into sex roles and the need to design risk reduction interventions that incorporate messages from multiple social sources. © 1996 John Wiley & Sons, Inc.     

Patient cost-benefits of realtime teledermatology--a comparison of data from Northern Ireland and New Zealand

As part of a randomized controlled trial of the costs and benefits of realtime teledermatology in comparison with conventional face-to-face appointments, patients were asked to complete a questionnaire at the end of their consultation. One hundred and nine patients took part in an initial teledermatology consultation and 94 in a face-to-face consultation. The proportion of patients followed up by the dermatologist was almost the same after teledermatology (24%) as after a hospital appointment (26%) and for similar reasons. Two hundred and three questionnaires were completed after the first visit and a further 20 after subsequent visits. Patients seen by teledermatology at their own health centre travelled an average of 12 km, whereas those who attended a conventional clinic travelled an average of 271 km. The telemedicine group spent an average of 51 min attending the appointment compared with 4.3 h for those seen at the hospital. The results of the present study, as in a similar study conducted in Northern Ireland, show that the economic benefits of teledermatology favour the patient rather than the health-care system.
