Background: The ¹³C-urea breath test is the best non-invasive test to validate Helicobacter pylori eradication. Serology is unreliable for this purpose due to the slow and unpredictable decline in the antibodies titer.

Objectives: To characterize a specific group of patients who were treated for H. pylori and tested for successful eradication by ¹³C-UBT[1] in our central laboratory and to correlate the eradication success rate with specific drug combinations, and to evaluate other factors that may influence eradication success.

Methods: ¹³C-UBT for H. pylori was performed in the central laboratory of Clalit Health Services. The breath test was performed by dedicated nurses in 25 regional laboratories and the samples were analyzed by a mass spectrometer (Analytical Precision 2003, UK). The physician who ordered the test completed a questionnaire computing demographic data (age, gender, origin), indication, use of non-steroidal anti-inflammatory drugs or proton pump inhibitor, and combination of eradication therapy.

Results: Of the 1,986 patients tested to validate successful H. pylori eradication, 539 (27%) had a positive test (treatment failure group) and 1,447 (73%) had a negative test (successful treatment group). Male gender, older age and European-American origin predicted better eradication rates. Dyspeptic symptoms and chronic PPI[2] therapy predicted treatment failure. Combination therapy that included clarithromycin had a higher eradication rate than a combination containing metronidazole. The combination of omeprazole, amoxicillin and clarithromycin achieved an eradication rate of 81.3%, which was better than the combination of omeprazole, metronidazole and clarithromycin (77.2%) (not significant), or of omeprazole, amoxicillin and metronidazole (66.1%) (P < 0.01).

Conclusion: Gender, age, origin, dyspepsia and PPI therapy may predict H. pylori eradication results. Our findings also support an increase in metronidazole resistance of H. pylori strains in Israel, as described in other countries. We recommend combination therapy with omeprazole, amoxicillin and clarithromycin and avoidance of metronidazole as one of the first-line eradication drugs.

The threat of a disease outbreak resulting from biologic warfare has been of concern for the Israeli health system for many years. In order to be prepared for such an event the health system has formulated doctrines for various biologic agents and defined the logistic elements for the procurement of drugs. During the last 4 years, and especially after the West Nile fever epidemic in 2000, efforts to prepare the healthcare system and the relevant organizations were accelerated. The Director-General of the Ministry of Health nominated a Supreme Steering Committee to fill in the gaps and upgrade the preparedness of the health system for an unusual disease outbreak. This committee and its seven subcommittees established appropriate guidelines, communication routes among different organizations, and training programs for medical personnel. The anthrax outbreak in the United States found the healthcare system in the hub of the preparation process, and all modes of action were intensified. Further work by hospitals, primary care clinics and all other institutes should be initiated to maintain a state of proper preparedness.

Background: During a period of 13 months - 1 October 2000 to 31 October 2001 – 586 terror assault casualties were treated in the trauma unit and emergency department of Hadassah University Hospital (Ein Kerem campus); 27% (n = 158) were hospitalized and the rest were discharged within 24 hours.

Objectives: To analyze the special requirements of a large number of victims who received treatment during a short period.

Methods: Data were attained from the main admitting office and the trauma registry records. Analysis was conducted of: age, gender, mechanism of injury, anatomic site of injury, Injury Severity Score (ISS), and length of stay.

Results: Males comprised 81% of the hospitalized patients. The majority of the injuries (70%) were due to gunshot wounds and 31% of the hospitalized patients were severely injured (ISS ≥ 16). Twelve patients died, yielding a mortality rate of 7.5%.

Conclusion: The nature of the injuries was more complex and severe than trauma of other etiologies, as noted by the mean length of stay (10.2 vs. 7.2 days), mean intensive care unit stay (2.8 vs. 0.9 days), and mean operations per patient (0.7 vs. 0.5). The mean insurance cost for each hospitalized terror casualty was also higher than for other trauma etiologies (US$ 3,200 vs. 2,500).

Background: Lithium has been a part of the psychiatric pharmacopoeia for more than half a century. Its efficacy is marred by a narrow therapeutic index and significant toxicity.

Objectives: To increase physicians’ awareness of the various manifestations of lithium intoxication.

Methods: We reviewed the clinical data of cases of lithium poisoning occurring in a municipal hospital during a 10 year period.

Results: Eight patient records were located. The mortality rate was 12.5%. All patients were women and the mean age was 66.4 years. The most common symptoms were neurological. One illustrative case is described in detail with lithium serum levels showing the usual two-phase decline.

Conclusions: Lithium poisoning can present in many forms. Increased physician awareness and the early use of effective treatment, mainly hemodialysis, will prevent mortality and protracted morbidity associated with this condition.
