Background: Due to extensive activity at sea, certain human populations, especially fishermen, are exposed to direct contact with the sea's inhabitants, including dangerous marine animals.

Objectives: To characterize and assess the extent of injuries caused by marine organisms along the Mediterranean coast of Israel, their type, severity and medical treatment given.

Methods: Data were obtained from a survey on injuries from marine organisms conducted among professional fishermen along the Mediterranean coast of Israel and from medical records reporting toxicological consultations provided by the Israel Poison Information Center.

Results: Injuries caused by marine organisms are not rare in Israel, but most cases are not severe. The most common injuries reported by fishermen were caused by stingrays (30%), weaver fish (22%), rabbit fish, (13%) and marine catfish (10%) – a new Red Sea immigrant. Most fishermen tend to treat such injuries themselves and sought medical help only when an unknown venomous fish was involved. Most cases of severe toxicity were due to secondary infection. Data from the IPIC[1] indicated that 64% of the calls were from the general public and the rest came from physicians in health care facilities. Four sources of injuries were identified: cleaning and preparing fish for consumption, during leisure water sport activities, handling marine aquaria, and fishing. Most cases from the IPIC were graded as minor severity (85%) and were treated symptomatically.
Conclusions: We recommend that medical facilities be installed at the fishing anchorages and that a separate category be established for injuries by marine organisms to facilitate epidemiological data collection from health care facilities

Background: Scombroid fish poisoning is an acute illness caused by consumption of fish containing high concentrations of histamine. Improper handling of fish leads to bacterial contamination. Bacterial enzymes convert histidine to histamine. Symptoms develop quickly and resemble an immunoglobulin E-mediated allergic reaction. The diagnosis is often missed. Serious complications (e.g., bronchospasm, hypotension) are infrequent.

Objectives: To evaluate the prevalence and characteristics of scombroid fish poisoning in Israel as reported to the National Poison Information Center.

Methods: We conducted a retrospective poison center chart review from January 2005 to December 2007.

Results: During the study period, 21 events of scombroid poisoning involving 46 patients were recorded. Tuna was the commonest fish consumed (84.7%). Clinical manifestations developed within 20 minutes in 65.2% of the patients. The main clinical manifestations included rash (41%), flushing (37%), gastrointestinal complaints (37%) and headache (30.4%). About 25% had abnormal vital signs; two patients developed hypotension. Treatment was supportive and included mainly H₁-antagonists (65.2%) and fluids (13%). Five patients were initially misdiagnosed as having an allergic reaction and were treated with corticosteroids (four patients) and epinephrine (one patient).

Conclusions: Scombroid fish poisoning should be suspected in patients with histamine-like manifestations that are temporally related to fish (mainly tuna) consumption, especially in outbreaks. Although scombroid poisoning is often self-limited and responds well to antihistamines, prolonged observation may be required as severe toxicity can supervene. Proper handling of fish and urgent notification of the Ministry of Health are mandatory in order to prevent this potentially serious public heath problem.
 

Background: Intrapartum risk is based mainly on obstetric history, which is lacking in primiparous women.

Objectives: To ascertain whether the traditional known risk of primiparity is an independent variable for both maternal and neonatal outcome.

Methods: All women admitted to labor during March-April 2002 were canvassed for eligibility for participation in the study based on an obstetric risk scoring system developed and validated for our population. During the study period, 1473 women presented for delivery. Of these, 298 women (20%) were eligible according to the exclusion criteria as "low risk" parturients: 135 (45%) were primiparous and 163 (55%) were multiparous (2–5 births).

Results: After correction for significant confounding factors, primiparity was revealed as an independent significant risk factor for instrumental delivery (odds ratio 15.5, 95%confidence interval 1.88–125) and for early postpartum hemorrhage (OR[1] 5.6, 95%CI[2] 1.9–16.6).

Conclusions: This study highlights early postpartum hemorrhage as a significant risk for primiparous women, independent of mode of delivery, and also confirms previous reports of maternal complications requiring transfer from birth centers/home deliveries to tertiary centers.

Since the beginning of medical history, ethics has interested medical practitioners. The subject has become particularly important in recent years due to the huge advancements in medicine and medical technology and has elicited much public interest. While international ethical principles and guidelines have been established, classical Jewish tradition has always placed great emphasis on bioethics. Prof. Avraham Steinberg’s monumental Encyclopedia of Jewish Medical Ethics presents the subject comprehensively and in depth. We propose a bioethics syllabus, to be integrated into the medical curriculum in three stages: i) preclinical – covering basic ethical concepts and principles, relevant history, and ethical codes; ii) clinical  – covering bioethical topics relating to the human life cycle; iii) prior to students' final examinations and further specialization – covering bioethical topics relating to their personal interests. Steinberg’s Encyclopedia is an ideal basis for the development of a professional course, including Jewish traditional aspects. Such a course would provide future physicians with a varied cultural and intercultural background, help shape their image, and improve the quality of medical care.

Medical screening is not a tangible existent tool in autoimmune disorders as it is in other illnesses. Numerous attempts are made to identify individuals destined to develop an autoimmune disease, including analysis of the genetic background, which along with the immunological profile, may assist in identifying those individuals. If these efforts turn out to be successful they may lead to the possibility of proactive measures that might prevent the emergence of such disorders. This review will summarize the attempts made to pursue autoantibodies specific for the central nervous system as potential predictors of autoimmune neurological disorders.

Background: Fanconi anemia complementation group C and Bloom syndrome, rare autosomal recessive disorders marked by chromosome instability, are especially prevalent in the Ashkenazi* Jewish community. A single predominant mutation for each has been reported in Ashkenazi Jews: c.711+4A→T (IVS4 +4 A→T) in FACC[1] and BLM^Ash in Bloom syndrome. Individuals affected by both syndromes are characterized by susceptibility for developing malignancies, and we questioned whether heterozygote carriers have a similarly increased risk.

Objectives: To estimate the cancer rate among FACC and BLM^Ash carriers and their families over three previous generations in unselected Ashkenazi Jewish individuals.

Methods: We studied 42 FACC carriers, 28 BLM^Ash carriers and 43 controls. The control subjects were Ashkenazi Jews participating in our prenatal genetic screening program who tested negative for FACC and BLM^Ash. All subjects filled out a questionnaire regarding their own and a three-generation family history of cancer. The prevalence rates of cancer among relatives of FACC, BLM^Ash and controls were computed and compared using the chi-square test.

Results: In 463 relatives of FACC carriers, 45 malignancies were reported (9.7%) including 10 breast (2.2%) and 13 colon cancers (2.8%). Among 326 relatives of BLM^Ash carriers there were 30 malignancies (9.2%) including 7 breast (2.1%) and 4 colon cancers (1.2%). Controls consisted of 503 family members with 63 reported malignancies (12.5%) including 11 breast (2.2%) and 11 colon cancers (2.2%).

Conclusions: We found no significantly increased prevalence of malignancies among carriers in at least three generations compared to the controls.

Background: The Pittsburgh Sleep Quality Index is a standardized self-administered questionnaire for the assessment of subjective sleep quality. It has been translated into several languages and is widely used in clinical research studies.

Objectives: To assess the reliability and validity of the Pittsburgh Sleep Quality Index Hebrew translation in a sleep clinic sample and in comparison with the Technion Mini Sleep Questionnaire.

Methods: The PSQI[1] was translated into Hebrew based on standard guidelines. The final Hebrew version (PSQI-H) was administered to 450 patients from two sleep clinics and to 61 healthy adults from the community as a non-clinical control sample. The MSQ[2] was administered to 130 patients in one sleep clinic.

Results: For the PSQI-H[3], Cronbach's-alpha scores for sleep clinic and non-clinical samples were 0.70 and 0.52 respectively and 0.72 combined. Clinical sample scores were significantly higher than the non-clinical group, indicating lower sleep quality for the former. Significant correlations were found between the MSQ subscores and PSQI-H component scores for common underlying constructs.

Conclusions: The PSQI-H differentiated between clinical and non-clinical samples and showed adequate reliability and good validity. It may be used as a standardized tool for the assessment of subjective sleep quality in clinical research studies conducted in the Hebrew-speaking population.
