Injuries in national karate competitions in Finland

The injuries sustained in 6 national karate competitions in Finland were studied by analyzing data from 450 bouts during the season 1991–1992. The analyzed data included a personal interview with each competitor and detailed information on the bouts and any injuries sustained. The overall probability of injury was 0.28 per bout. These injuries occurred to 16% of the 647 competitors. Occurrence of injury was greatest among adult men, which was pronounced in final bouts. Of all injuries diagnosed by the physicians for the competitions, more than 95% were localized to the head. The majority of these were minor injuries. Experienced competitors were more injury-prone than beginners. On the other hand, none of the background factors studied significantly affected the probability of injuring one's opponent. Most injuries and penalties, as well as full scores, were caused by direct punches to the head. From these findings it was concluded that a protective guard for the head together with modification of competition rules could significantly reduce injuries.     

Endocrinology: Intravenous albumin does not prevent the development of severe ovarian hyperstimulation syndrome in an in-vitro fertilization programme

A cohort study was undertaken to compare the effect at the timeof oocyte retrieval of the i.v. administration of either 1000ml of lactated Ringer' solution or 1000 ml of a 5% solutionof human albumin on in-vitro fertilization patients at riskfor severe ovarian hyperstimulation syndrome (OHSS). A totalof 207 patients with an oestradiol concentration > 10 000pmol/l and/or > 15 follicles (>10 mm diameter) on theday of human chorionic gonadotrophin (HCG) injection were reviewed.Of these, 158 women received 500 ml of lactated Ringer’ssolution both before and after egg retrieval, and 49 women receivedtwo infusions of 500 ml of 5% human albumin in normal salineat the time of egg retrieval. Severe OHSS developed in two patientswho received human albumin and in 10 women who did not receivethe albumin. This difference was not statistically significant.There were no differences between the two groups in terms ofage, number of follicles punctured at transvaginal oocyte retrievalor oestradiol concentration at the time of HCG injection. Theadministration of a 5% human albumin solution does not preventthe development of severe OHSS in at risk patients. It doesappear to blunt the severity of the condition.

Evaluating the Effectiveness of Premarital Prevention Programs: A Meta‐Analytic Review of Outcome Research

We present a comprehensive, meta‐analytic review and critical evaluation of outcome research pertaining to the effectiveness of premarital prevention programs. Results revealed that the mean effect size for premarital programs was .80, which means that the average person who participated in a premarital prevention program was significantly better off afterwards than 79% of people who did not participate. Stated differently, the average participant in a premarital program tends to experience about a 30% increase in measures of outcome success. Our findings suggest that premarital prevention programs are generally effective in producing immediate and short‐term gains in interpersonal skills and overall relationship quality and that these improvements are significantly better than nonintervention couples in these areas. However, because of a lack of extended follow‐up research, conclusions about long‐term effectiveness remain elusive. We propose implications for future research, education, and policy.     

A placebo controlled trial of remoxipride in the prevention of relapse in chronic schizophrenia

Sixty-two DSM III chronic schizophrenic inpatients were selected for a double-blind, placebo controlled, multi-centre, relapse prevention study of remoxipride, a selective dopamine (D₂)-receptor antagonist. After a 1 month placebo washout, 23 patients had relapsed and were withdrawn. Of the remaining patients 19 were randomised to remoxipride (150–300 mg daily) and 20 to placebo. Their median age was 58 years, 26 were male, and the median duration of illness was 33 years. After 24 weeks a further total of 8 remoxipride and 17 placebo patients had been withdrawn. Excluding three patients withdrawn for reasons other than relapse, the comparative relapse rates were 37% and 75%, respectively (P=0.015). Efficacy analyses using clinical global impression (P=0.04) and change in BPRS scores (P=0.016) were in favour of remoxipride. Extrapyramidal symptoms were minimal in both groups. Treatment emergent adverse events were similar in the two groups. Remoxipride is therefore of potential value as a safe drug which is both effective and well tolerated in the long term management of chronic schizophrenic patients.     

Groups for poorly socialized children in the elementary school

Many inner-city children, living in resource-poor violent communities, have low self esteem, deficient social skills and do not know how to prevent and cope with provocation and conflict. A group therapy model is described for assisting elementary school children deal with these problems. Groups were led by volunteer mental health professionals in two inner-city elementary schools.     

Serogroup B meningococcal disease in the Norwegian armed forces: What can we learn from an inconclusive vaccine protection trial?

Military recruits serving in the armed forces were severelyaffected during the latest serogroup B meningococcal epidemicin Norway. The risk of developing systemic meningococcal disease(SMD) proved highest during the first 12 weeks of service. Adouble-blind, placebo-controlled protection trial with a meningococcalouter membrane vesicle vaccine took place between 1988 and 1991,but the number of proven SMD cases was too low to allow forany conclusions. However, the results of a parallel efficacystudy of the same vaccine among students in secondary school,cross-society examinations for asymptomatic throat carriageof meningococci and recent immunogenicity studies after two-and three-dose vaccination schedules, suggest that a basic immunizationof young teenagers followed by a booster injection at enrolmentwould contribute significantly to preventing SMD in the armedforces.

Skilled birth attendant competence: an initial assessment in four countries, and implications for the Safe Motherhood movement.

OBJECTIVES: Percentage of deliveries assisted by a skilled birth attendant (SBA) has become a proxy indicator for reducing maternal mortality in developing countries, but there is little data on SBA competence. Our objective was to evaluate the competence of health professionals who typically attend hospital and clinic-based births in Benin, Ecuador, Jamaica, and Rwanda. Methods: We measured competence against World Health Organization's (WHO) Integrated Management of Pregnancy and Childbirth guidelines. To evaluate knowledge, we used a 49-question multiple-choice test covering seven clinical areas. To evaluate skill, we had participants perform five different procedures on anatomical models. The 166 participants came from facilities at all levels of care in their respective countries. Results: On average, providers answered 55.8% of the knowledge questions correctly and performed 48.2% of the skills steps correctly. Scores differed somewhat by country, provider type, and subtopic. Conclusion: A wide gap exists between current evidence-based standards and current levels of provider competence.     

Testing the Theoretical Fit of an Abseiling Harness: A Study of an Australian Primary and Secondary Prevention Program

A theoretical model of prevention addressing adolescents at-risk of offending was developed then utilised to assess a primary and secondary prevention program. The study of the wilderness-based practise was conducted between September 1992 and October 1994, adopting a pre-post-follow-up quasi-experimental design using waiting periods to establish treatment and control groups. Maturational changes were gauged over a 12 month period of 44 male and 18 female voluntary Australian adolescents between the ages of 15 and 25 years. Significant differences between the treatment and control groups in the psychometric areas of general self-esteem and self-actualisation were found establishing positive program effect on participants. Further, the long term effect of this program in preventing participants initial contact with court proceedings or reducing further involvement respectively, over a twelve month period was substantiated. It was shown that following this experience post program goals of employment and education for adolescents at-risk were positively influenced.
