The screening program in Israel for Tay-Sachs disease has proven very successful, giving Jewish couples a choice not to have affected children. The technology of carrier detection is now possible in several other severe genetic diseases that are relatively frequent among Jews. Due to the current confusion, a policy is needed to determine how the TSD screening program should be continued in the Israeli Jewish population. We propose that such a screening program include only mutations agreed by consensus as causing a disease severe enough to warrant the possibility of therapeutic abortion. We also propose that general screening include only mutations that are relatively frequent, taking into account the carrier frequencies in the Israeli Jewish population.

Background: The degree to which serum total cholesterol predicts cariovascular disease is uncertain. While most authors have placed TC among the most powerful risk indicators of CVD, some have claimed that it predicted CVD in women only, or even not at all.

Objective: To determine the predictive value of serum total cholesterol relative to diabetes, smoking, systolic blood pressure and body mass index (kg/m2), for cardiovascular disease mortality in 3,461 occupationally active Israeli males.

Methods: A prospective follow-up was carried out for the years 1987-1998 to determine the effect of age, smoking habits, a history of diabetes, SBP, BMI and TC, at entry, on CVD mortality.

Results: There were 84 CVD deaths during a total of 37,174 person-years follow up. The hazard ratios (95% confidence intervals) for CVD mortality with respect to variables at entry were: diabetes 5.2 (2.1-13.2), age 2.2 (1.7-2.9), smoking 1.3 (1.0-1.8), SBP 1.4 (1.1-2.0), TC 1.5 (1.0-2.1) and BMI 1.2 (0.7-2.2). Among non-obese, non-diabetic, normotensive subjects the hazard ratio of TC adjusted for age and smoking was 1.16 (1.09-1.22) per 10 mg/dl. In the remaining subjects it was 1.04 (0.98-1.12) only. There was a significant interaction between TC and diabetes, hypertension or obesity (P=0.003).

Conclusions: In this population of Israeli males we found an interaction between TC and other risk indicators for CVD. Confirmation is required for the unexpected finding that the predictive value of TC for CVD mortality among non-diabetic, non-obese and normotensive subjects exceeded that among subjects with either of these risk factors.
 

There is increasing evidence to suggest that aspirin and other non-steroidal anti-inflammatory drugs reduce the risk of colorectal cancer. This observation is supported by animal studies that show fewer tumors per animal and fewer animals with tumors after administration of several different NSAIDs. Intervention data in familial adenomatous polyposis have established that the effect is exerted on the process of human colonic adenoma formation. Supportive evidence in sporadic colorectal neoplasia, derived from 22 of 24 studies (both case-control and cohort), found a reduced risk in men and women for cancers of the colon and the rectum and for both aspirin and the other NSAIDs. Earlier detection of lesions as a result of drug-induced bleeding does not seem to account for these findings. Although the molecular mechanism responsible for the chemopreventive action of this class of drugs is not yet completely understood, the protection may affect several pathways including both cell cycle arrest and induction of apoptosis.

In the third millennium the question is not if but how. Based on the consistency of epidemiological, clinical and experimental data, the association between regular long-term aspirin or NSAIDs intake and a decreased death rate from colorectal cancer is sound and there is no need for further placebo trials. At the same time, despite this consistency there is no clear data on the dose, duration or frequency of use for cancer-preventive activity.

Background: Burn trauma occurs mostly in young children. Burn injury in the pediatric age group has multiple-aspect sequelae.

Objectives: To characterize the profile of the injured pediatric burn patient, thus targeting the most vulnerable pediatric group.

Methods: Between 1 January and 31 December 1996, a total of 9,235 pediatric patients were admitted for various traumatic injuries (burns, lacerations, fractures, etc.) to the Emergency Medicine Department of Schneider Children’s Medical Center. We conducted a retrospective study of the patients’ charts, including demographic data, which were stored in a computerized database, for statistical evaluation. The characteristics of pediatric burn patients were examined and compared with other pediatric trauma patients.

Results: Of the total patient population, 282 (3.1%) suffered from burns (37% females, 63% males). The most frequent burn injury was scald burn (58%). The pediatric group that was most exposed to burns was 13–18 month old males.

Conclusions: Having identified the high risk group among the pediatric burn patients, we suggest that prevention programs be directed towards this group in order to reduce further risk of burn injury.
