Prevalence of anti-hepatitis A antibodies, hepatitis B viral markers, and anti-hepatitis C antibodies among immigrants from the former USSR who arrived in Israel during 1990-1991.

The goal of this study was to assess the susceptibility of the sub-population of over 500,000 immigrants from the former USSR who came to Israel during 1989-94 to HAV infection, and to provide military physicians with estimates of the prevalence of HBV and HCV carriage in this sub-population. 987 males aged 17-49 and 195 females aged 17-19, reporting to military recruitment offices between December 1991 and March 1992 were tested. Anti-HAV, anti-HBV antibodies and hepatitis B surface antigen (HBsAg) were detected by using standard enzyme immunoassay (EIA) tests, and anti-HCV antibodies by a second-generation EIA and confirmed by a third-generation INNO-LIA test. It was found that in the 17-19-year age-group the prevalence of anti-HAV antibodies was 37%, anti-HBV was 12.8%, HBsAg was 3.0% and anti-HCV 1.3%. All markers were higher among males. The prevalence of anti-HAV and anti-HBs antibodies increased with age among males. That of HBsAg and anti-HCV antibodies increased with age overall. In the multiple logistic regression analysis, HAV and HBV seropositivity were significantly associated with the mother's education and republic of origin. It was concluded that the prevalence of anti-HAV antibodies is similar to that among the local population, which should not be considered at a higher risk of infection during military service. On the other hand, the higher prevalence of HBsAg and anti-HCV antibodies in this sub-population should heighten the awareness of the possibility of chronic liver pathology.

Osteoporosis of the spine, pelvis and hand. A comparative study in a femoral neck fracture series.

In a comparative study of the degree and prevalence of osteoporosis in the hand, pelvis and spine of a group of femoral neck fractures in the elderly, it was noted that spinal osteoporosis was much more frequent and appeared much earlier than pelvic osteoporosis. Similarly, a one way correlation existed between osteoporosis of the hand and spine. No relationship was noted between osteoporosis of the pelvis as measured by our criteria and by the Singh technique.

A trial of the reactogenicity and immunogenicity of an inactivated hepatitis A vaccine.

Purified, formaldehyde-inactivated and alum-adjuvanted hepatitis A virus (HAV) vaccines have recently become available for clinical trials. The vaccine is administered intramuscularly in a schedule of 0, 1, and 6 months. The aim of the study was to evaluate the reactogenicity and immunogenicity of an inactivated hepatitis A (HA) vaccine. Three groups of volunteers comprised the study population: 28 volunteers without antibody to HAV were given HA vaccine and, for comparison, 43 subjects received hepatitis B vaccine for possible adverse reactions to the HA vaccine; 12 other subjects received immunoglobulin alone. Each 1 ml dose of HA vaccine contained 720 enzyme units or about 100 ng of antigen. Anti-HAV was determined by means of a commercial assay (Abbott Laboratories: HAV-EIA), and by a more sensitive ELISA. No significant adverse reactions were reported. In the group that received HA vaccine, 4 weeks following the first dose all had detectable antibodies (> or = 20 mIU/ml) by the sensitive ELISA. By commercial HAV-EIA, at 20 weeks following the second dose 75.0% had detectable antibodies, and after the third vaccine all had detectable antibodies. This new inactivated HA vaccine is highly immunogenic and had no significant side effects.

The epidemiology of femoral neck fractures in Jerusalem. A prospective study (1967-1971).

A prospective study of 570 patients with fracture of the upper end of the femur was carried out between 1967 and 1971 in Jerusalem. Of three distinct ethnic groupings, Western or Ashkenazi females and Eastern or Sephardi males produced the highest incidence of fractured neck of the femur proportional to their makeup in the population at risk. No explanation for this is forthcoming as both groups are of differing sex and race. The age and sex incidence of these fractures in the Eastern and Western ethnic groups in this city showed a distinct resemblance to their geographicaly counterparts in other studies. There is an interesting seasonal pattern of incidence of fractures in females and correlation with increased physical activity during the three special holiday periods.
