Background: Uveal melanoma is the most common primary intraocular tumor in adults. In the last two decades the Hadassah-Hebrew University ocular oncology clinic has become a referral center for uveal melanoma patients.

Objectives: To describe the characteristics of uveal melanoma patients in Israel, their treatment modalities and outcomes during the years 1988–2007.

Methods: Data were collected from the files of uveal melanoma patients in the departments of ophthalmology and oncology in our facility. Statistical analysis was performed using JMP statistical software.

Results: Data were available for 558 patients. The annual incidence of uveal melanoma in the last 5 years was 47.2 ± 7.1 new cases per year (mean ± standard error). There were 309 women (55.4%). The age at diagnosis was 60.8 ± 16.5 years (range 5–95). Overall, 6.6%, 16.8% and 86.9% involved the iris, ciliary-body and choroid, respectively. Tumors were classified as small, medium and large (9.0%, 64.5% and 17.9%, respectively) according to the COMS grouping criteria. The most common primary treatment was brachytherapy (74%), followed by enucleation (17.9%). Local recurrence was noted in 11.1% of patients, while metastases developed in 13.3%. The 5, 10 and 15 year melanoma-related mortality rate was 11.4%, 17.0% and 23.3%, respectively. Of the overall study population 9.3% died of metastatic uveal melanoma.

Conclusions: Uveal melanoma patients in Israel have tumors with characteristics similar to those in other countries. Brachytherapy is the predominant treatment, the local recurrence rate is low, and survival is comparable to that reported in the medical literature.

Background: The role of endoscopic ultrasound in evaluating the response of esophageal cancer to neoadjuvant chemotherapy is controversial.

Objectives: To evaluate the accuracy of EUS[1] in restaging patients who underwent NAC[2].

Methods: The disease stage of patients with esophageal cancer was established by means of the TNM classification system. The initial staging was determined by chest and abdominal computed tomography and EUS. Patients who needed NAC underwent a preoperative regimen consisting of cisplatin and fluouracil. Upon completion of the chemotherapy, patients were restaged and then underwent esophagectomy. The results of the EUS staging were compared with the results of the surgical pathology staging. This comparison was done in two groups of patients: the study group (all patients who received NAC) and the control group (all patients who underwent primary esophagectomy without NAC).

Results: NAC was conducted in 20 patients with initial stage IIB and III carcinoma of the esophagus (study group). Post-chemotherapy EUS accurately predicted the surgical pathology stage in 6 patients (30%). Pathological down-staging was noted in 8 patients (40%). However, the EUS was able to observe it in only 2 patients (25%). The accuracy of EUS in determining the T status alone was 80%. The accuracy for N status alone was 35%. In 65% of examinations the EUS either overestimated (35%) or underestimated (30%) the N status. Thirteen patients with initial stage I-IIA underwent primary esophagectomy after the initial staging (control group). EUS accurately predicted the surgical pathology disease stage in 11 patients (85%).

Conclusions: EUS is an accurate modality for initial staging of esophageal carcinoma. However, it is not a reliable tool for restaging esophageal cancer after NAC and it cannot predict response to chemotherapy.

Background: Dyslipidemia remains underdiagnosed and undertreated in patients with coronary artery disease. The Computer-based Clinical Decision Support System provides an opportunity to close these gaps.

Objectives: To study the impact of computerized intervention on secondary prevention of CAD[1].

Methods: The CDSS[2] was programmed to automatically detect patients with CAD and to evaluate the availability of an updated lipoprotein profile and treatment with lipid-lowering drugs. The program produced automatic computer-generated monitoring and treatment recommendations. Adjusted primary clinics were randomly assigned to intervention (n=56) or standard care arms (n=56). Reminders were mailed to the primary medical teams in the intervention arm every 4 months updating them with current lipid levels and recommendations for further treatment. Compliance and lipid levels were monitored. The study group comprised all patients with CAD who were alive at least 3 months after hospitalization.

Results: Follow-up was available for 7448 patients with CAD (median 19.8 months, range 6–36 months). Overall, 51.7% of patients were adequately screened, and 55.7% of patients were compliant with treatment recommended to lower lipid level. A significant decrease in low density lipoprotein levels was observed in both arms, but was more pronounced in the intervention arm: 121.9 ± 34.2 vs. 124.3 ± 34.6 mg/dl (P < 0.02). A significantly lower rate of cardiac rehospitalizations was documented in patients who were adequately treated with lipid-lowering drugs, 37% vs. 40.9% (P < 0.001).

Conclusions: This initial assessment of our data represent a real-world snapshot where physicians and CAD patients often do not adhere to clinical guidelines, presenting a major obstacle to implementing effective secondary prevention. Our automatic computerized reminders system substantially facilitates adherence to guidelines and supports wide-range implementation.

Background: The Israel National Poison Information Center, Rambam Health Care Campus, provides telephone consultations on clinical toxicology as well as drug and teratogen information around the clock. The Center participates in research, teaching and regulatory activities, and also provides laboratory services.

Objectives: To analyze data on the epidemiology of poisonings and poison exposures in Israel.

Methods: We conducted computerized queries and a descriptive analysis of the medical records database of the IPIC[1] during 2007.

Results: Overall, 26,738 poison exposure cases were recorded, a 118.5% increase compared to 1995. Children under 6 years old were involved in 45% of cases; 73% of the calls were made by the public and 25.5% by physicians; 74.4% of exposures were unintentional and 9.2% intentional. Chemicals were involved in 37.9% of cases, pharmaceuticals in 44.2%, bites and stings in 4.3% and poisonous plants in 1.2%. Substances most frequently involved were analgesics, cleaning products and antimicrobials. Clinical severity was moderate/major in 3.5%. Substances most frequently involved in moderate/major exposures were insecticides, drugs of abuse and corrosives. Eight fatalities were recorded – three unintentional exposures (all chemicals) and five intentional (chemicals, medications, drugs of abuse).

Conclusions: The rates of poison exposures and poisonings in Israel have increased significantly, contributing substantially to morbidity and mortality. The IPIC database is a valuable national resource for collecting and monitoring cases of poison exposure and can be used as a real-time surveillance system. It is recommended that reporting to the IPIC become mandatory and that its activities be adequately supported by national resources.

Background: Parental fear and misconceptions about fever are widespread in western society. Ethnicity and sociodemographic factors have been suggested as contributing factors.

Objectives: To test the hypothesis that undue parental concern about fever is less in traditional than in western cultural-ethnic groups.

Methods: Bedouin (traditional society) and Jewish (western society) parents of children aged 0–5 years with fever were interviewed in a pediatric emergency unit. Interviews were conducted in the parents' most fluent language (Hebrew or Arabic). A quantitative variable (a 9 item “fever phobia” scale) was constructed.

Results: The parents of 101 Jewish and 100 Bedouin children were interviewed. More Bedouin parents were unemployed, had less formal education and had more and younger children than the Jewish parents. Parents of both groups expressed erroneous beliefs and practices about fever; quantitative but not qualitative differences in fever phobia variables were documented. Compared with their Jewish counterparts, more Bedouin parents believed that fever may cause brain damage and death, administered antipyretic medications for temperature ≤ 38ºC and at excessive doses, and consulted a physician within 24 hours even when the child had no signs of illness other than fever (all P values < 0.001). The mean fever phobia score was higher in the Bedouin than in the Jewish group (P < 0.001). By multivariate analysis, only the cultural-ethnic origin correlated with fever phobia.

Conclusions: A higher degree of fever phobia was found among parents belonging to the traditional Bedouin group as compared to western society parents.
