Background: The authors describe a multifaceted cross-infection control program that was implemented to contain an epidemic of multidrug-resistant microorganisms (MRO) (carbapenem resistant Pseudomonas aeruginosa and Acinetobacter baumannii; extended spectrum β-lactamase producing Klebsiella pneumoniae, Escherichia coli, Enterobacter Cloacae, and Proteus mirabilis; and ‎methicillin-resistant Staphylococcus aureus and Candida species). 

Objectives: To assess the effect of a control program on the incidence of cross-infection with MRO.

Methods: Clinical criteria triaged patients into a high-risk wing (HRW) or a low-risk wing (LRW). Strict infection control measures were enforced; violations led to group discussions (not recorded). Frequent cultures were obtained, and use of antibiotics was limited. Each quarter, the incidence of MRO isolation was reported to all staff members. 

Results: Over a 6 year period, 1028 of 3113 patients were placed in the HRW. The incidence of MRO isolation within 48 hours of admission was 8.7% (HRW) vs. 1.91% (LRW) (P < 0.001). Acquired MRO infection density was 30.4 (HRW) vs. 15.6 (LRW) (P < 0.009). After the second year, the incidence of group discussions dropped from once or twice a month to once or twice a year.

Conclusions: These measures contained epidemics. Clinical criteria successfully triaged HRW from LRW patients and reduced cross-infection between the medical center wings. The quarterly reports of culture data were associated with improved staff compliance. MRO epidemic control with limited resources is feasible. 

 

Objectives: To determine the overall prevalence of PBC[1] in southern Israel and the specific rates for different immigrant groups between January 1993 and October 2004.

Methods: Multiple case-finding methods were used to identify all cases of PBC in the study region. Age-adjusted prevalence rates were compared among the different immigrant groups.

Results: A total of 47 cases of PBC were identified with an overall prevalence of 55 cases per million. All patients were women, and all except for a Bedouin Arab were Jewish. Foreign-born patients comprised 70% of our PBC cohort even though they represent only 45.4% of the regional population. This predominance of immigrants did not change when the rates were adjusted for age (P < 0.001). The prevalence rates were 40, 177, and 58 cases per million for those born in Israel, North Africa or Asia, and Eastern Europe, respectively. The age-specific prevalence rate for women older than 40 years varied from 135 cases per million among those born in Israel to 450 among immigrants from Eastern Europe and the former USSR to 700 cases per million among immigrants from North Africa and Asia.

Conclusions: The prevalence of PBC in southern Israel is similar to that reported from some European countries. The rate is much higher among Jews than Arabs and among immigrants to Israel compared to native Israelis.

Microscopic colitis is an idiopathic chronic inflammatory bowel disease presenting with watery diarrhea. While colonoscopy and radiology findings are normal, the colon shows striking pathologic findings, including lymphocytic colitis and collagenous colitis. The clinical course is usually benign with sustained remission. Recent medical evidence shows that bismuth and budesonide are effective treatments.

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.
