Recent events have significantly increased concern about the use of biologic and chemical weapons by terrorists and other countries. Since weapons of mass destruction could result in a huge number of casualties, optimizing our diagnostic and therapeutic skills may help to minimize the morbidity and mortality. The national demands for training in medical aspects of nuclear, biologic and chemical warfare have increased dramatically. While Israeli medical preparedness for non-conventional warfare has improved substantially in recent years especially due to extensive training programs, a standardized course and course materials were not available until recently. We have developed a core curriculum and teaching materials for a 1 or 2 day modular course, including printed materials.

The chemical warfare agent sulfur mustard affects primarily the eyes, skin and respiratory tract. Of these, ocular injury is the most immediate and distressing. Learning to recognize ocular injury enables the treating physician to provide early and suitable treatment, which will reduce complications and allow the victim a rapid recovery.

Background: Ciguatera poisoning is the commonest fish-borne seafood intoxication. It is endemic to warm water tropical areas and is caused by consumption of bottom-dwelling shore reef fish, mostly during spring and summer. The causative agent, ciguatoxin, is a heat-stable ester complex that becomes concentrated in fish feeding on toxic dinoflagellates. The common clinical manifestations are a combination of gastrointestinal and neurologic symptoms. Severe poisoning may be associated with seizures and respiratory paralysis.

Objective: To describe a series of patients who sustained ciguatera poisoning from an uncommon region and an unexpected source.

Patients: Two families complained of a sensation of “electrical currents,” tremors, muscle cramps, nightmares, hallucinations, agitation, anxiety and nausea of varying severity several hours after consuming rabbitfish (“aras”). These symptoms lasted between 12 and 30 hours and resolved completely. The temporal relationship to a summer fish meal, the typical clinical manifestations along with the known feeding pattern of the rabbitfish suggested ciguatera poisoning.

Conclusions: The Eastern Mediterranean basin is an unusual region and the rabbitfish an unusual source for ciguatera poisoning. There are no readily available and reliable means for detecting ciguatoxin in humans. A high index of suspicion is needed for diagnosis and a thorough differential diagnosis is essential to eliminate other poisonings, decompression sickness and encephalitis. Supportive therapy is the mainstay of treatment.

Background: The modest clothing that Orthodox Jewish women wear exposes very little of their skin to sunlight. Under these conditions they may develop vitamin D deficiency, even in sunny Israel.

Objectives: To determine and compare the vitamin D nutritional status in Jewish orthodox mothers to that of non-orthodox mothers who live in the same metropolitan area in Israel.

Methods: 25-Hydroxyvitamin D was measured by compe­titive protein-binding radioassay in the sera of 341 Jewish Israeli mothers (156 orthodox and 185 non-orthodox). The sera were obtained 48-72 hours after childbirth during the late summer of 1998 and the spring of 1999.

Results: The mean (SD) serum concentration of 25-OHD was significantly (P<0.002) lower (13.5 ± 7.5 ng/ml) in the orthodox than in the non-orthodox mothers (18.6 + 9.6 ng/ml). Vitamin D deficiency (<5 ng/ml) and insufficiency (<10 ng/ml) were more common in the orthodox mothers (5.1% and 32.7% respectively) than in the non-orthodox mothers (2.7% and 13%, respectively). In subgroups of mothers supplemented with 400 units of vitamin D daily during pregnancy, vitamin D deficiency and insufficiency were less common (2.2% and 13%, respectively) in orthodox and non-orthodox mothers (0% and 8.1%, respectively). Vitamin D insufficiency was more common in the winter than in the summer only among non­orthodox mothers.

Conclusions: The high prevalence of vitamin D deficiency and insufficiency in Israeli mothers raises the question whether vitamin D supplements should be given to pregnant women in Israel, at least to orthodox mothers.

Background: Hypertension is one of the most prevalent vascular diseases in the adult population. It is an important determinant of atherosclerosis in adolescents and young adults. There is to date no information on blood pressure in children of the Israeli Arab population.

Objectives: To study blood pressure in Israeli Arab children and adolescents.

Methods: Blood pressure measurements were taken in the supine position in 4,488 Israeli Arab children and adolescents of both sexes aged 6–17 years. Height and weight were also determined. Correlation was investigated between systolic and diastolic blood pressure, body mass index, gender, and age.

Results: The systolic and diastolic blood pressures were similar in both sexes for all age groups up to 14 years of age. Systolic blood pressure was significantly (P<0.001) higher in males aged 15–17 years  (120±13 vs. 111±12 mmHg, 123±13 vs. 113±14.0 mmHg, and 123±18 vs. 111±14 mmHg, respectively). Diastolic blood pressure was higher in males aged 15–17, with a statistically significant difference for age 17 only (75±12 vs. 69±13 mmHg). Blood pressure was elevated in 322 students in the initial screening (7.17%), with a decrease to 2.18% when this group was rescreened 2 weeks later. The systolic blood pressure in our group is higher than that in Jewish Israeli children of Asian and North African origin, and in American children. It is similar to the systolic blood pressure of European children and Jewish children born in Israel. The diastolic blood pressure in our group is higher than that in all groups of Israeli Jewish children and American children of different ethnic groups.

Conclusions: Israeli Arab children and adolescents have higher blood pressure levels than their Israeli Jewish counterparts. Further studies are required to confirm this observation.

Background: Although the onset of fever in children often prompts parents to seek immediate treatment, the general level of parental knowledge on pediatric fever and administration of antipyretic medications is unknown. Parents without a basic understanding of treatment principles may give their children incorrect doses of medication. Overdosing may cause drug toxicity, while underdosing may lead to unnecessary, repeated clinic and/or emergency room visits.

Objectives: To assess parental decision-making with regard to treating fever in children, and its effectiveness, and to suggest methods for improving the level of treatment.

Methods: In this cross-sectional self-reported survey, questionnaires were completed by 650 parents who sought medical assistance for a child under the age of 10 years. Parents represented various socioeconomic levels, educational backgrounds and religious affiliations.

Results: Ninety-six percent of parents treated fevers that reached 38.5°C, and 77.6% treated fevers of only 38°C. Acetaminophen was the treatment of choice for 96% and dipyrone for 4%. Parental sources of information for managing and administering antipyretic drugs were medical personnel (40.7%), mother's or grandmother's experience (30%), and the enclosed leaflet or instructions on the bottle (29.3%). Forty-three percent of the parents administered the recommended dosage (10–20 mg/kg), whereas 24.3% used less and 32.7% used more; 11% exceeded a daily dosage of 120 mg/kg. 

Conclusions: A total of 57% of parents treated children with incorrect doses of antipyretic drugs. In 11% of the children treated, the daily dose was at a level that could cause severe toxicity. Parental knowledge of the treatment of fever must be improved.
