Background: Lung percutaneous needle biopsy (PNB) is routinely used to diagnose lung cancer. The most prevalent complications of PNB are pneumothorax and bleeding. Differences in characteristics of medical procedures between rural and urban hospitals are well known.

Objectives: To compare characteristics of patients and lesions between two hospitals and to evaluate whether lung PNB complications differ in rural vs. urban settings.

Methods: The authors examined case records of 561 patients who underwent lung biopsy at two different medical centers in Israel: Tel Aviv Sourasky Medical Center (urban) and Barzilai Medical Center (rural). To evaluate the complication rates, the authors analyzed findings from chest X-ray performed 2 hours after biopsy and computed tomography (CT) images at the site of biopsy.

Results: The study comprised 180 patients who underwent lung biopsy at Barzilai and 454 at Sourasky. The rate of pneumothorax did not differ between centers (12% at Barzilai and 19% at Sourasky, P = 0.08). Distance from pleura was positively correlated to pneumothorax occurrence in both centers; however, neither lesion size nor lesion locus was found to be a risk factor for pneumothorax. Mild bleeding at the biopsy site occurred equally at Barzilai and Sourasky (32% vs. 36%, P = 0.3, respectively). Furthermore, immediate CT post-biopsy at Barzilai showed 95% negative predictive value, showing that a CT scan performed immediately after lung biopsy cannot replace the routine follow-up chest X-ray in predicting iatrogenic pneumothorax.

Conclusions: CT-guided percutaneous lung biopsies are comparable between rural and urban hospitals regarding procedure characteristics and complication rates.

Background: Vitamin D is essential for skeletal health. Because peak bone mass accrual occurs during childhood and adolescence, vitamin D insufficiency during this period of life could cause adverse health outcomes.

Objectives: To explore the potential sex differences in anthropometric indicators and vitamin D status among primary school-age children.

Methods: A modified food-frequency intake questionnaire was completed by 116 pre-pubertal children (52 girls, 64 boys). Body measurements were recorded and blood was drawn to assess vitamin D status. All children were of Arab-Israeli origin and lived in villages or rural areas in the north-east area of Israel.

Results: Prevalence of obesity was higher among girls (34%) compared to boys (21.9%, P = 0.018). All the children were vitamin D insufficient, and 80% were deficient. Plasma vitamin D was significantly higher among boys (12.4 ng/ml) compared to girls (9.1 ng/ml, P < 0.01). A significant negative correlation was found between vitamin D status and weight percentile for girls (r = -0.43, P < 0.05) but not for boys. There was a trend toward a statistically significant inverse correlation between vitamin D status and body fat percent in the girls (r = -0.37, P = 0.07). Sex frameworks are important for the understanding of the determinants of health and the development of effective health promotion programs.

Conclusions: Pre-pubertal girls in Arab villages should be provided with tailor-made nutrition and physical activity programs for promoting health.

Background: Ethiopian immigration to Israel was initiated in 1981. Most immigrants were rural dwellers who migrated first to Addis Ababa or Gondar, where they waited for eligibility status from Israel to leave Ethiopia. Soon after arriving in Israel, all immigrants were offered screening tests for human immunodeficiency virus (HIV) and syphilis.

Objectives: To evaluate the association of age, gender, marital status and length of time spent in urban areas in Ethiopia with the prevalence of HIV and syphilis seropositivity.

Methods: All adult Ethiopian immigrants who arrived at the Jerusalem immigration center between 1999 and 2002 and consented to HIV and syphilis screening tests were interviewed.

Results: Altogether, 678 immigrants (51% females) were screened; 39 (5.8 %) were seropositive for HIV and 33 (4.9%) for syphilis. The length of time the immigrants spent in Ethiopian cities before leaving for Israel was significantly associated with HIV: odds ratio (OR) 2.76, 95% confidence interval (CI) 1.13–6.71, and syphilis seropositivity  OR 3.87, 95%CI  1.56–9.62.

Conclusions: The length of transit time Ethiopian immigrants from rural areas spend in Ethiopian cities is significantly associated with HIV and syphilis seropositivity. Efforts should be made to shorten this time in order to reduce the risk of infection

Background: The incidence and prevalence of coronary heart disease (CHD) among Bedouins living in the Negev region was very low until the 1960s. During the past 50 years this pattern has changed: in parallel to the changes in lifestyle and nutrition in the Bedouin population, a rapid increase in incidence and mortality from CHD occurred. The relationship between the rise in CHD incidence and the degree of urbanization in this population has not been investigated to date. The study hypothesis was that the prevalence of risk factors and the outcome of myocardial infarction in Bedouins differ between those settled in permanent villages and those remaining in unrecognized villages.

Objectives: To compare the prevalence of cardiovascular risk factors, clinical characteristics, and in-hospital management of a first acute myocardial infarction (AMI) in two Bedouin groups: those residing in permanent villages versus those residing in unrecognized villages.

Methods: We conducted a retrospective analysis of in-hospital data of 352 patients admitted with a first AMI during the period 1997–2003 to Soroka Medical Center, the only medical facility in the region.

Results: There were no differences between the two groups regarding the major cardiovascular risk factors and outcome. A relatively greater number of patients from urban areas underwent catheterization of any sort during their hospitalization (primary, rescue, and risk stratification; P = 0.038). No significant difference was found between the two groups in the type of catheterization performed (P = 0.279).

Conclusions: We found no differences in the clinical characteristics and in-hospital management of patients with AMI between Bedouins residing in permanent villages versus unrecognized villages.

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.
