Background: The southern region of Israel has recently experienced an influx of African refugees from the Eastern Sub-Sahara desert area. These influxes led to a significant increase in incidence of tuberculosis (TB) in that region.

Objectives: To review the data of African refugees diagnosed with TB between January 2008 and August 2010 at a tertiary care regional hospital.

Results: Twenty-five TB cases were diagnosed, 22 of which presented with pulmonary TB, 3 with  extra-pulmonary TB (EPTB), and 7 with combined pulmonary and EPTB. Only one case had concomitant human immunodeficiency virus (HIV) infection and multidrug-resistant TB. Fifteen patients underwent extensive radiological investigations including chest, abdominal and spine computed tomography, 1 was reviewed by magnetic resonance imaging, and 9 underwent tissue biopsy. Eighteen patients were admitted as suspected TB and 4 as suspected pneumonia or pulmonary infiltrates that could have been defined as suspected TB. All 24 HIV-negative cases were sensitive to first-line drugs for TB except one case that was resistant to streptomycin and one to rifampicin. All patients responded well to first-line therapy. The average duration of hospitalization was 8.7 days (range 1–36). Following diagnosis 23 patients were transferred to a quarantine facility.

Conclusions: We identified overutilization of medical resources and invasive procedures. For African refugees from the eastern Sub-Sahara who were HIV-negative and suspected of having TB, a sputum acid-fast smear and culture should have been the primary investigative tools before initiating treatment with four drugs (first-line), and further investigations should have been postponed and reserved for non-responders or for patients for whom the culture was negative. Physicians should maintain a high index of suspicion for EPTB in this population.

 Colorectal cancer is a leading cause of cancer death in Israel. Our current understanding of the colorectal adenoma-carcinoma sequence has led to the use of screening for timely detection of polyps and cancer. Digital examination of the rectum is a test that can be performed by all doctors. Fecal occult blood testing, flexible sigmoidoscopy and colonoscopy are the standard screening techniques for patients. Computerized tomography colonography is now entering this field. This review discusses the merits and uncertainties of these strategies as related to the risk of colorectal cancer in selected populations.

Background: The Dead Sea in Israel has a very high mineral content. Near-drowning in the Dead Sea is expected to result in severe electrolyte abnormalities and respiratory failure. Previous limited studies reported a high mortality rate.

Objective: To evaluate the clinical and biochemical manifestations and disease outcome of near-drowning in the Dead Sea.

Methods: Data were abstracted from the archives of Soroka University Medical Center. The cohort comprised 69 patients who nearly drowned in the Dead Sea.

Results: The median age of the patients was 68 years (range 21–84). There were two major manifestations of near-drowning in the Dead Sea: electrolyte imbalance and acute lung injury. Serum calcium, magnesium and phosphorus (but not sodium, potassium and chloride) were abnormal in most patients. Median serum electrolyte levels (and range) on admission were 10.9 mEq/dl (9–24) for calcium, 4.3 mEq/dl (1–30) for magnesium, and 4.1 mEq/dl (2–9) for phosphorus. These levels quickly normalized with forced diuresis within 24 hours. Acute lung injury – namely, hypoxic bilateral pneumonitis – occurred in 29 patients. Mechanical ventilation was required in 11 patients. Sixty-five patients recovered fully, while the remaining 4 had minor sequelae.

Conclusions: Near-drowning in the Dead Sea is a syndrome of severe electrolyte abnormalities and lung injury. Early treatment, with forced diuresis and supportive care, results in prompt recovery.
