Background: The incidence of congenital cytomegalovirus in Israel has never been determined, either in general or in relation to various population subgroups. We recently proved the utility of newborn urine polymerase chain reaction as a screening tool for congenital CMV[1].

Objectives: To define the incidence of congenital CMV infection in two different subpopulations, as a model for the entire population of Israel.

Methods: Urine specimens were randomly collected from 2,000 newborns in Shaare Zedek Medical Center, Jerusalem, and HaEmek Medical Center, Afula (1,000 specimens each). These hospitals have many characteristic differences, presumably representing the diverse population of Israel. Urine specimens were subjected to a CMV PCR[2] reaction and positive specimens were validated by urine viral culture. Maternal seroprevalence was determined in a representative sample of the mothers in each hospital. Epidemiologic characteristics of the mothers were extracted from hospital records and compared.

Results: The population in Shaare Zedek Medical Center was mostly Jewish (95.8%) and urban (87.0%), as compared to that of HaEmek Medical Center (49.2% and 61.0%, respectively, P < 0.01). Nevertheless, CMV seroprevalence was similar: 81.5% and 85%, respectively. Ten (1.0%) and 4 (0.4%) newborns, respectively, were found to have congenital CMV infection (not significant).

Conclusions: The combined incidence of congenital CMV infection in the study population was 0.7% (95% confidence interval 0.3–1.0%). If this rate is extrapolated to the entire population of Israel, then a total of 945 cases of congenital CMV can be expected among the 135,000 annual deliveries. A nationwide screening program for congenital CMV should be considered.

Background: The use of complementary and alternative medicine has increased over the last decade in the western world.

Objectives: To evaluate the extent and characteristics of CAM[1] use among cancer patients in northern Israel.

Methods: Telephone interviews were conducted with 2,176 newly registered cancer patients or their family members, at least 1 year following referral.

Results: The rates of CAM use varied significantly according to demographic characteristics and chemotherapy treatment, from 3% in the basically educated elderly group up to 69% of educated Israeli-born Jews younger than 70 years receiving chemotherapy. The overall rate of CAM use was 17%. The most influential factors determining CAM use were academic or high school education, chemotherapy treatment, Israel as country of birth, and age 41–50 years. All patients used CAM in addition to conventional therapies. Less than half of them reported it to their physicians. The most frequently used treatments were various chemical, biological, botanic and homeopathy remedies. Friends and relatives were the main recommenders of CAM. Most CAM users reported that they used CAM because they believed it “strengthens the immune system,” alleviates side effects of chemotherapy, improves quality of life and helps to overcome pain and stress, and 62% of them reported subjective beneficial effects.

Conclusions: A predicting module of CAM user patients was built, which may help physicians initiate conversations with their patients on CAM use. Expanding physicians' knowledge on CAM methods will encourage them to provide additional advice, promote the use of beneficial therapies, and inform patients about potentially harmful methods.

Highly active antiretroviral therapy has dramatically improved the quality of life and life expectancy of patients with human immunodeficiency virus. However, the prolonged use of HAART[1] leads to severe metabolic adverse events. Both HIV[2]infection and HAART can cause changes in lipid and glucose metabolism as well as elevation of blood pressure, promoting the development of atherosclerosis. Cardiovascular diseases have become a major cause of mortality among HIV-infected subjects who respond well to antiretroviral therapy. Nevertheless, a proper lifestyle and pharmacologic intervention can improve cardiovascular risk factors in the HIV-treated population and significantly reduce healthcare investments in the treatment of future cardiovascular complications in this population. In this review we summarize the current knowledge of CVD[3] prevention and treatment in HIV patients.

Background: Torsade de pointes is rarely associated with chronic amiodarone treatment, despite the effect of amiodarone on QT interval prolongation.

Objective: To identify risk factors and associated conditions that may cause TdP[1] in patients on chronic amiodarone treatment.

Methods: We reviewed the data of six consecutive patients on chronic amiodarone treatment who were admitted to the intensive cardiac care unit due to syncope and TdP.

Results: The patients’ median age was 73.5 years, and five were women. Concomitantly, loratadine was given to two patients and trazodone to one patient. Associated and attributing conditions to the development of TdP were hypokalemia in three patients, drug-induced bradycardia in one and reduced left ventricular function in four.

Conclusions: TdP associated with chronic amiodarone treatment may occur when amiodarone is co-administered with drugs that may potentially prolong QT interval. Additional risk factors for amiodarone-associated TdP include female gender, hypokalemia, reduced left ventricular function and bradycardia.

Background: While increasing numbers of patients require prolonged mechanical ventilation, resources for weaning are either limited (ICU beds) or inadequate (general wards).

Objectives: To report on our initial experience over a 7 month period with an eight-bed mechanical ventilation weaning unit.

Methods: Sixty-nine patients requiring MV[1] for >10 days were admitted to the unit (nurse:patient ratio 1:4). Data collected included reason for MV, duration of hospital stay, and MVWU[2] course. Outcome results (successful weaning and mortality) were compared to those in historic controls (patients ventilated in the general wards over a 4 month period prior to the MVWU; n = 100).

Results: The mean age of the patients was 68 ± 16.6 years and hospital stay prior to MVWU admission 28.6 ± 24.2 days (range 10–72). The main reasons for MV included acute exacerbation of chronic obstructive pulmonary disease (31%) and recent pneumonia (28%). Mean MVWU stay was 13.5 ± 15.7 days (range 1–72 days). Thirty-four patients (49%) underwent tracheostomy. Fourteen patients required admission to the ICU[3] due to deterioration in their status. Twenty-nine patients (42%) were successfully weaned and discharged to the wards. A further 20 patients were transferred to the chronic ventilation unit of a regional geriatric rehabilitation hospital, where 5 were subsequently weaned and 15 required prolonged ventilation. Compared to controls (matched for age and reason for mechanical ventilation), more MVWU patients underwent successful weaning (49% vs. 12%, P < 0.001) and their mortality rate (n = 12) was significantly lower (17% vs. 88%, P < 0.001).

Conclusion: The higher level of care possible in a MVWU may result in a significantly improved rate of weaning and lower mortality. The assessment of long-term outcome in patients discharged to pulmonary rehabilitation centers requires further investigation.

Background: Adult-to-adult living donor liver transplantation is becoming an alternative to cadaveric transplantation in urgent and elective settings. Donor selection crucially affects donor safety and recipient outcome.

Objective: To present our algorithm of urgent and elective donor selection.

Methods: Urgent selection is expeditious and protocol‑based. Elective selection permits a comprehensive process. Both include medical, psychosocial and surgical-anatomic evaluations. Liver volumes and vascular anatomy are evaluated with computerized tomographic angiography. Informed consent is obtained after painstaking explanations. Independent institutional committees review and approve all cases.

Results: Between July 2003 and June 2004 we evaluated 43 potential live donors for 12 potential recipients (fulminant hepatic failure, n=5; chronic end-stage liver disease, n=6); primary graft non-function, n=1). Thirty-three candidates (76%) were excluded due to blood type incompatibility (n=14, 42%), incompatible anatomy (n=8, 24%) – including problematic volume distribution (n=2) or vascular anatomy (n=6) – psychosocial issues (n=4, 12%), or medical co-morbidity (n=7, 22%). Five recipients (FHF[1], n=4; chronic ESLD[2], n=1) were successfully transplanted from living donors. In the acute setting, two patients (FHF, PGNF[3]) died in the absence of an appropriate donor (cadaveric or living donor). In the elective group, one patient died of unexpected variceal bleeding and one received a cadaveric graft just before the planned living donor transplantation was performed. One candidate was transplanted overseas and two cases are scheduled. The ratio of compatibility for donation was 34% (10/29) for blood type-compatible candidates.

Conclusions: Donor selection for living donor liver transplantation is a complex, labor-intensive multidisciplinary process. Most exclusions are due to blood type incompatibility or anatomic details. Psychosocial aspects of these donations warrant special attention.

Profound neonatal hypoglycemia is one of the leading causes of brain injury. Hypoglycemic encephalopathy is caused by lack of glucose availability to brain cells. Although sharing a similar pathogenesis with hypoxic-ischemic encephalopathy, hypoglycemic brain insult has distinctive metabolic, brain imaging, electroencephalographic, and histopathologic findings.
