Background: One of the measures adopted in Israel since 1959 as part of the tuberculosis control program was screening children aged 12–13 years old. The screening comprised single-step tuberculin skin testing using the Mantoux method.

Objective: To assess the efficacy of tuberculin skin screening for TB[1] in schoolchildren in southwestern Israel as well as the compliance to treatment for latent tuberculosis infection.

Methods: We retrospectively reviewed the records of children in the Ashkelon region who underwent a tuberculin skin test during the period 1995–99.

Results: Of the 28,016 eligible children, 27,232 were tested. In 923 children, mostly from the former USSR and Ethiopia, an induration of 10 mm or more was found. Only 52 Israeli-born children tested positive. Tuberculosis was found in seven children with a positive test, five of whom were from Ethiopia. All children who tested positive were referred to the local TB clinic; only 266 children (28.8%) presented. Only 151 completed the recommended treatment of isoniazid for 6 months. Thus, although screening included most of the targeted children aged 13, only a third of them presented to a TB clinic, of whom only about half completed treatment of latent infection.

Conclusions: Our results indicate that the current policy of screening for latent TB in our region is ineffective in terms of implementation of the recommended treatment. We suggest that only high risk groups be screened, and that a concerted effort be made to implement treatment.

Background: Breast cancer is the most common malignancy among women in Israel and throughout the world. Israeli women aged 50–75 years are advised to undergo a mammographic screening examination every 2 years. However, the lack of a structured referral system is reflected in the low utilization rate of mammography.

Objectives: To describe an innovative program in which family physicians in an urban clinic developed a model framework for referrals, coordinated with radiologists and surgeons, aimed at increasing compliance among women referred for mammography.

Methods: A community-based study was conducted, outside of the regular reception hours, in a neighborhood practice with a population of 527 women aged 50–75. A referral system under the supervision of family physicians was designed, and the women received appointments for mammography at specified days and hours. The results of the examination were sent to the physician who used dedicated time to continue the diagnostic and/or therapeutic process, as appropriate. At the physician’s instructions a research assistant contacted the women who did not keep their appointments and scheduled a second appointment.

Results: In 1993, the year prior to the study, when women referred themselves for mammography, the utilization rate was 9%. During the study year the utilization rate was 77%. Women born in Europe or America had higher compliance rates than women born in Asia or Africa (81% vs. 72%, respectively). Married women were more compliant than unmarried women (81% vs. 70%, respectively). No correlation was found between compliance and age, family history of cancer in general, or breast cancer in particular. Six new cases of breast cancer were detected.

Conclusions: The initiative of family physicians increased the utilization of mammography among women under their care. Family physicians allocated time outside of their regular reception hours for the program. A relatively large number of new malignancies were found, but this impression should be confirmed or negated by a large-scale study using the same methods.
 

Background: Familial Mediterranean fever is a genetic disease in which some characteristic gene mutation have been found.

Objective: To analyze the phenotype-genotype correlations in North African Jews and Armedians with FMF.

Methods: We studied MEFV gene mutations and phenotype-genotype correlations in North African Jews and Armedians with Familial Mediterranean Fever living in France.

Results: M694V mutation was the most common mutation in Jews and in Armenians. Patients with M6801 homozygosity or M6801/M694V compound heterozygosity had a phenotype as severe as patients with M694V homozygosity.

Conclusions: This study characterizes the phenotype-genotype in specific ethnic groups of patients with FMF.

Background: A beneficial effect was observed in patients with psoriasis vulgaris following balneotherapy with Dead Sea bath salt.

Objectives: To evaluate the possible role of trace elements in the effectiveness of balneotherapy. 

Methods: Serum levels of 11 trace elements were analyzed in 23 patients with psoriasis vulgaris who participated in a double-blind controlled study of balneotherapy, with either Dead Sea bath salt (12 patients) or common salt (11 patients). Thirteen healthy volunteers served as controls.

Results: The mean pre-treatment serum levels of boron, cadmium, lithium and rubidium were significantly lower in patients compared to controls, whereas the mean pre-treatment serum level of manganese was significantly higher in patients compared to controls. Balneotherapy with Dead Sea bath salt resulted in a significant decrease (P = 0.0051) in the mean serum level of manganese from 0.10 ± 0.05 mmol/L to 0.05 ± 0.02 mmol/L. The mean reduction in the serum level of manganese differed significantly (P = 0.002) between responders (% Psoriasis Area and Severity Index score reduction ³ 25) and non-responders (% PASI score reduction < 25). Following balneotherapy with Dead Sea bath salt the mean serum level of lithium decreased in responders by 0.01 ± 0.02 mmol/L whereas its level in non-responders increased by 0.03 ± 0.03 mmol/L. (P = 0.015).
Conclusions: Manganese and lithium may play a role in the effectiveness of balneotherapy with Dead Sea bath salt for psoriasis.

Background: Following the recent drought in Ethiopia, the Jewish Agency, aided by the Israel Ministry of Foreign Affairs, launched a medical relief mission to a rural district in Ethiopia in May-August 2000.

Objectives: To present the current medical needs and deficiencies in this representative region of Central Africa, to describe the mission’s mode of operation, and to propose alternative operative modes.

Methods: We critically evaluate the current local needs and existing medical system, retrospectively analyze the mission’s work and the patients’ characteristics, and summar­ize a panel discussion of all participants and organizers regarding potential alternative operative modes.

Results: An ongoing medical disaster exists in Ethiopia, resulting from the burden of morbidity, an inadequate health budget, and insufficient medical personnel, facilities and supplies. The mission operated a mobile outreach clinic for 3 months, providing primary care to 2,500 patients at an estimated cost of $48 per patient. Frequent clinical diagnoses included gastrointestinal and respiratory tract infections, skin and ocular diseases (particularly trachoma), sexually trans­mitted diseases, AIDS, tuberculosis, intestinal parasitosis, malnutrition and malaria.

Conclusions: This type of operation is feasible but its overall impact is marginal and temporary. Potential alternative models of providing medical support under such circum­stances are outlined.
 

Background: The method of midline Iaparotomy incision and closure remains a complex surgical problem.

Objective: To compare the mechanical properties at the interface of midline laparotomy incision made by scalpel versus electrocutting current in rats.

Methods: A sharp midline laparotomy incision was made in 60 Wistar female rats using a scalpel or electrocautery to open the fascia. The fascial and skin wounds were closed separately with a continuous nylon. Fascial specimens were analyzed for mechanical properties at the midline incision using a loading machine. The load-extension curve was recorded during tensile loading at a steady extension rate of 15 mm/mm.

Results: There was no statistically significant difference between the two groups in either wound-bursting force (PPEAK) or the strain energy spent until the point of measured PPEAK. Each load-extension curve showed a characteristic pattern in all rats. Tissue stiffness was greater in the scalpel group than in the electrocautery group (P= 0.02). Correlations were found between tissue stiffness and strain energy, between tissue stiffness and bursting force, and between bursting force and strain energy.

Conclusions: While tissue stiffness was greater when a scalpel was used compared to electrocutting to incise the midline abdominal fascia in rats, there was no difference in the bursing force required to disrupt the wound.

Background: It is not clear to what extent the drug economy in Israel's health maintenance organizations is responsive to major healthcare reforms.

Objective: To provide information on how drug expendi­tures, revenues, net costs and drug utilization have changed in the wake of the 1995 National Health Insurance Law in Israel.

Methods: This study compares trends in aggregate sick fund expenditures, revenues (patient co-payment) and net costs (expenditures less revenues) in Israel's four health maintenance organizations for the 3 year period 1992-1994 prior to the introduction in 1995 of the NHI Law, with that of the 4 year period 1995-1998 following its introduction. This analysis is similarly carried out for Israel’s largest HMO, Clalit Health Services, and for the three smaller HMOs combined.

Results: The pace of growth in the pre-NHI era in drug expenditures and particularly in drug revenues was drastically reduced in the NHI era - whether measured as totals or as per insured person (age-adjusted) or in real terms at constant medicine prices. These trends were mirrored to a large extent in

Conclusions: The impact of the NHI Law on the HMO drug economy has been substantial. The evidence suggests a decline in both the qualitative (basket of drugs consumed) and quantitative (volume of drugs consumed) elements of growth. These changes in expenditure and revenue trends are discussed in the light of the evolving involvement of the Israel Ministry of Health in drug policy within the framework of the NHI, with emphasis on the basket of drugs reimbursed and co­payments for prescriptions.
