Unintentional childhood poisoning in the Sharon area in Israel: a prospective 5-year study.

OBJECTIVES: To study the epidemiology and risk factors for unintentional exposure to poisoning among the Jewish and the Arab population in the Sharon area in Israel. METHODS: We prospectively evaluated visits to the pediatric emergency department because of unintentional poisoning exposure, at the Meir General Hospital. We collected demographic data, substance exposure data, and the clinical outcome of the poisoning. RESULTS: During the 5 years of the study, 502 children were evaluated for unintentional poisoning, 84% Jewish and 16% Arabs; 88.5% occurred in children younger than 5 years, with a peak incidence at the age of 2 years (39.5%). Medications including hormones, vitamins, and antibiotics were the most common cause of exposure. Most children (95%) had no symptoms or abnormal findings on physical examination (84%), and most (85%) were discharged after several hours of observation. However, children of Arab origin presented with severe clinical manifestations because of a high rate of pesticide poisoning. There was 1 death from organic phosphate poisoning. CONCLUSION: Exposure to poisoning is commonly encountered in children. Pesticides exposure is more common in the Arab community and is usually associated with more severe clinical manifestations. Educational preventive programs are mandatory.

The changing epidemiology of viral hepatitis A in Israel.

BACKGROUND: Between 1970 and 1979, there was an increase in the incidence of viral hepatitis in Israel with a shift of peak incidence to an older age in the Jewish population, followed by a declining trend during the early 1980s. In July 1999 universal immunization of infants against hepatitis A was introduced. OBJECTIVE: To evaluate the chan-ges in the epidemiology of viral hepatitis A in Israel during the past decade. METHODS: Viral hepatitis is a notifiable disease in Israel and cases are reported to the regional health offices, which in turn provide summary reports to the Ministry of Health's Department of Epidemiology. The data in this study were derived from the summary reports and from results of seroprevalence studies. RESULTS: Following the increase in the incidence of reported viral hepatitis (mainly due to type A) between 1970 and 1979, the rates then stabilized and around 1984 began to decline until 1992. Since then there has been a slight increase. Whereas until 1987 the rates were consistently higher in the Jewish population, since then they are higher in the Arab population. The shift in the peak age-specific incidence from the 1-4 to the 5-9 year age group observed in the Jewish population around 1970 occurred 20 years later in the Arab population. The previously described seasonality is no longer evident. Recent seroprevalence studies indicate that by age 18 years only about 30-40% of the Jewish population have anti-hepatitis A antibodies. CONCLUSIONS: The decline in the incidence of hepatitis probably reflects the changing socioeconomic condition occurring at different times in the two major population groups. Since hepatitis A accounts for almost all the acute viral hepatitis in Israel, the universal vaccination of infants introduced in 1999 should substantially lower the morbidity within the next few years.

Epidemiological characteristics of spotted fever in Israel over 26 years.

During the summer of 1997, 2 confirmed and several suspected fatal cases of spotted fever (SF) occurred in previously healthy young adults in Israel. This unusual cluster of events stimulated the current study. The incidence of SF in Israel from 1971-98 was analyzed. Incidence increased until 1980, declined until 1994, and increased slightly from 1994-97. Incidence was higher during the summer, among children aged 0-9 years, and in rural settlements in central Israel. From 1971-1997, 31 deaths were reported, mostly in the elderly. The deaths that occurred in 1997 are a reminder that, despite the fact that morbidity due to SF is described mainly in children, SF can have a rapidly fatal outcome in healthy young adults. Thus, even during periods of low incidence, careful monitoring and high awareness for prompt diagnosis and treatment are needed.
