Trends in youth mortality in Israel, 1984-1995.

BACKGROUND: Investigation of causes of death can help inform intervention policy aimed at reducing preventable mortality. OBJECTIVES: To assess mortality causes and trends over time and identify target groups with excessive mortality rates among Israeli youth aged 10-24, in order to formulate an intervention policy for prevention of adolescent mortality. METHODS: Mortality data for Israeli residents aged 10-24 were extracted from the Central Bureau of Statistics computerized death certificate file for the period 1984-95. Trends were evaluated by cause of death and demographic characteristics. RESULTS: The crude mortality rate among Israeli youth aged 10-24, during 1993-1995, was 39.6 per 100,000. Rates were 2.7 times higher among males, increased with age, and reached a peak among 18-21 year olds. Rates were 1.4 times higher among Arabs than among Jews. The sharp increase in mortality among Jewish males of military service age (18-21 years) was due mainly to motor vehicle crashes and suicide. Although overall mortality decreased by 9.4% from 1984-86 to 1993-95, the gap between the subgroups increased. MVC-related mortality increased over time by 100% among Arab males. The rate of completed suicide among Jewish males increased by 110%. Although injury-related mortality is lower in Israel compared with the U.S., similar demographic differentials and trends were found in both countries. CONCLUSIONS: Suicide among Jewish males of military service age, as well as MVC fatalities among Arab males, present a growing public health issue. Intervention strategies should therefore be targeted towards these subgroups in order to minimize the rates of preventable death.

Recurrent gastrointestinal Henoch-Schönlein purpura.

A 7-year-old boy was seen for severe abdominal pain, vomiting, and a 2.0-kg weight loss of 2 weeks duration. Stools were Hemoccult positive. Upper gastrointestinal (UGI) endoscopy showed multiple, raised red lesions in the duodenal bulb and descending duodenum. Although the patient did not have the typical cutaneous eruption, other findings such as acute onset of abdominal pain in a previously healthy boy, absence of infectious or surgical lesions, and more importantly endoscopic changes seen typically in the descending duodenum, led to the likely diagnosis of Henoch-Schönlein purpura (HSP). The patient was treated with prednisone and the duodenal lesions resolved. The diagnosis of HSP was confirmed 24 weeks after the initial symptom when he developed a palpable purpuric rash over both legs. Thirteen months following the initial symptoms and 6 months after the onset of rash, severe abdominal pain with epigastric tenderness recurred and stools were Hemoccult positive. UGI endoscopy showed multiple, raised red lesions in the descending duodenum as seen earlier. The patient was diagnosed with recurrent HSP. This presentation is atypical because of the abnormally long interval between the onset of abdominal pain and the appearance of the skin rash, and unique because of the endoscopically demonstrated recurrent gastrointestinal lesions.

The MGDS examination: a systematic approach. 1. General preparation and Part I of the examination. Member in General Dental Surgery.

This paper is the first in a series of four which present a systematic approach to colleagues who are preparing for and sitting the examination for the Diploma of Membership in General Dental Surgery (MGDS) of The Royal College of Surgeons of England. Although some details may differ, the general principles set out in the four papers apply equally to the MGDS examinations of the other Royal Surgical Colleges.

Surgery for unstable angina.

A series of 84 patients with unstable angina, treated surgically by grafting procedures between October 1970 and September 1976, have been reviewed. The study indicates that extensive coronary artery disease is common in these patients, and suggests that operation may favourably influence mortality, both immediate and delayed, but does not reduce the risk of myocardial infarction. Eighty per cent of the patients were relieved of angina and able to lead a reasonably normal existence.

Bannayan-Riley-Ruvalcaba syndrome: spectrum of intestinal pathology including juvenile polyps.

Bannayan-Riley-Ruvalcaba syndrome (BRRS) is a disorder that includes juvenile polyposis as part of its pathologic spectrum, and it recently has been shown to share phenotypic and genotypic features with Cowden's disease. In existing literature, descriptions of intestinal pathology in patients with BRRS are relatively sparse and occasionally erroneous. We describe the intestinal pathology in multiple specimens from three children with BRRS. Examination of gastrointestinal biopsies from these children revealed predominantly colonic and rectal polyps with the histology of juvenile polyps. Additionally, two cases with clusters of ectopic ganglion cells within the lamina propria, one in a colonic polyp and one in a duodenal biopsy, and an atypical polyp were observed. Bannayan-Riley-Ruvalcaba syndrome should be included in the list of differential diagnostic considerations when a child or young adult presents with a juvenile polyp, particularly if unusual histologic features such as atypical polyps or ectopic ganglion cells are encountered.
