Background: The European Quality of Life 5-Dimensions questionnaire is one of the most commonly used measures of health-related quality of life.

Objectives: To present the feasibility, reliability, and validity of the Hebrew version of the EQ-5D[1].

Methods: We conducted face-to-face interviews with a representative sample (n=1666) of the Israeli Jewish population. The data collected included demographic and medical information, and self-valuation of health using the EQ-5D descriptive system, Visual Analogue Scale and Time Trade-Off. Construct validity was assessed by assuming that older individuals, those with a greater burden of diseases, and those reporting experience with their own severe illness would have lower EQ-5D indexes, VAS[2] and TTO[3] values. Test-retest reliability was assessed in a small sample (n=50) that was reevaluated after a 3 week interval.

Results: Test-retest reliability of the EQ-5D and VAS was very high (r ≥ 0.85). Reliability of the TTO was moderate (r = 0.48). There were significant differences in the EQ-5D index, profiles, VAS and TTO between healthy and sick respondents and younger and older respondents, indicating good validity of the instrument.

Conclusions: The Hebrew translation of the EQ-5D is a practical, reliable and valid instrument for assessing the health-related quality of life of the general Israeli Jewish population.

Background: Depression is a leading cause of morbidity, disability and health care utilization. It is commonly encountered in primary care settings yet is often missed or suboptimally managed.

Objective: To summarize studies conducted in Israel on the prevalence of depression in primary care settings, its correlates, and predictors of treatment and outcome, and to discuss their implications for clinical practice and public health policy.

Methods: An electronic search was conducted using the MEDLINE and PsychINFO databases. The inclusion criteria were original studies that assessed aspects of depression in a population aged 18 or older, were conducted in primary care settings in Israel, and with sufficient detailed description of depression-related measures, study sample and outcome measures. Twelve articles reporting results from 7 studies met these criteria.

Results: The prevalence of current depression in primary care varied considerably across studies: 1.6–5.9% for major depression, 1.1–5.4% for minor depression, 14.3–24% for depressive symptoms. Depression was consistently related to female gender and few years of education, and was associated with disability, decreased quality of life, and increased health-related expenditure. Many cases of depression were undiagnosed and most patients had persistent depression or achieved only partial remission.

Conclusions: Depression represents a serious challenge for the primary health care system in Israel. Greater efforts should be focused on screening and treating depression in primary care. However, the studies reviewed here used different methodologies and assessed different aspects of depression, and, therefore, should be generalized cautiously. Systematic research on the prevalence, correlates and management of depression in primary care, with emphasis on collaborative care models, is strongly needed to inform research, clinicians and health care policy makers.

Background: The extent of medical and financial problems of polypharmacy in the elderly is disturbing, particularly in nursing homes and nursing departments.

Objectives: To improve drug therapy and minimize drug intake in nursing departments.

Methods: We introduced a geriatric-palliative approach and methodology to combat the problem of polypharmacy. The study group comprised 119 disabled patients in six geriatric nursing departments, and the control group 71 patients of comparable age, gender and co-morbidities patients in the same wards. After 12 months, we assessed whether any change in medications affected the death rate, referrals to acute care facility and costs.

Results: A total of 332 different drugs were discontinued in 119 patients (average of 2.8 drugs per patient) and was not associated with significant adverse effects. The overall rate of drug discontinuation failure was 18% of all patients and 10% of all drugs. The 1 year mortality rate was 45% in the control group but only 21% in the study group (P < 0.001, chi-square test). The patients’ annual referral rate to acute care facilities was 30% in the control group but only 11.8% in the study group (P < 0.002). The intervention was associated with a substantial decrease in the cost of drugs.

Conclusions: Application of the geriatric-palliative methodology in the disabled elderly enables simultaneous discontinuation of several medications and yields a number of benefits: reduction in mortality rates and referrals to acute care facilities, lower costs, and improved quality of living.

Objectives: To describe how an HMO[1] used its health information technology in a way that enables its management to receive updated online information on the demands of the insured, according to their distribution throughout the country during the time of the war in Lebanon in July-August 2006.

Methods: Data were derived from the computerized medical records of Maccabi Healthcare Services – the second largest HMO in Israel, providing care to more than 1.7 million members nationwide. Data on healthcare utilization by northern members were compared to the geographic distribution of clinics.

Results: The war was characterized by the massive evacuation of citizens southwards. During this period there was an abrupt decline in the utilization of medical services by northern members in the northern region. This decline returned to normal 10 days after the ceasefire. A reciprocal increase was noted in the use of health services by citizens from the north in other regions. This increase returned to normal after the war. No such pattern was noticed during the same period in 2005.

Conclusions: Real-time surveillance of trends in consumption of health services by citizens in times of regular daily living as well as during emergencies and wars is a vital management tool for medical directors responsible for providing health services.

Background: Laryngeal obstruction due to bilateral vocal cord immobility in adduction may cause dyspnea, hoarseness and dysphagia and can lead to dependence on a tracheostomy. Treatment poses a challenge because of the opposing functions of the larynx and the risk of neck and laryngeal tissue damage.

Objectives: To describe our experience with endoscopic CO₂-laser-assisted posterior ventriculocordectomy without tracheostomy for the treatment of bilateral vocal cord immobility in adduction.

Method: The study group consisted of five male and five female patients aged 17–81 years. The procedure was performed with an endoscope and operating microscope connected to a CO₂ laser. A C-shaped incision was made, and the posterior third of one vocal cord, the vocal process of the arytenoid, and the posterior third of the false vocal cord were excised. Tracheostomy was not performed.

Results: The technique allowed for a convenient approach to the difficult-to-view areas of the larynx. The procedure was short and bloodless, with minimal damage to laryngeal tissue and no local edema. Hospitalization time was short. Postoperatively, patients had sufficient breathing and mostly fair to good voice quality. None of the patients had severe aspirations and only three patients had mild aspirations.

Conclusions: We recommend this procedure for patients with bilateral vocal cord immobility prior to tracheostomy. Delaying surgery beyond the time of possible re-innervation may place the patient at risk of decompensation, which requires tracheostomy.

Background: Atopic dermatitis is a common disease in infants and children and the incidence appears to be rising.

Objectives: To determine the presentation, allergies, and outcome among Israeli infants and children.

Methods: Children with atopic dermatitis referred to the allergy clinic at a regional pediatric center were evaluated for their medical history and their allergy. The allergic assessment was determined by utilizing skin prick tests and/or serum specific immunoglobulin E concentrations. The children were reexamined again for all parameters at the end of the follow-up period.

Results: Forty-six children with atopic dermatitis were studied, 27 males (58.7%) and 19 females (41.3%). A family history of allergy was found in 19 (41.3%). The median age at presentation was 17 months. Of the 46 children 33 (71.7%) revealed an allergy to one or more of the allergens. The most common combination was allergy to food and house-dust mites. The mean follow-up time was 64 months. By the age of 8 years full recovery was seen in 16 patients, half of whom recovered within 3.3 years from the date of presentation. The probability of complete remission was 58%, and for either complete or partial remission 76%. Upon reevaluation at the end of the follow-up period some patients lost their sensitivities, while others, who had been allergic to foods, became sensitive to house-dust mites and/or pollens.

Conclusions: Atopic dermatitis is an allergic problem in the northern region of Israel, as it is in other parts of the world. Food allergy and house-dust mites are major contributors to the evolution of eczema.

Background: It has been argued that arginine replacement in locus16 (Arg16) of ß₂ adrenergic receptor with glycin (Gly16) increases asthma severity, while glutamin replacement in locus 27 (Gln27) with glutamic acid (Glu27) decreases it. In addition, ethnic dependency of these polymorphisms has been described, but few studies investigated its relation to asthma severity in a non-anglosaxic population.

Objectives: To investigate non-anglosaxic ethnic influences on ß₂AR[1] polymorphisms and its correlations to asthma severity.

Methods: Sixty-six Israeli Jewish and Arab asthmatics who had near-fatal asthma and/or severe nocturnal asthma and/or steroid-dependency were investigated for genetic polymorphisms of ß₂AR and compared to matched controls. The Jewish patients included both Ashkenazi (of East European origin) and non-Ashkenazi (originating from the Middle East or North Africa). The results were compared with those of ethnically matched 113 non-asthmatic Israelis, and of non-asthmatic Anglo-Saxons described in the literature.

Results: We found no significant genetic differences between the asthmatics and their controls or between the various ethnic groups of our population. However, the prevalence of Glu27 was significantly lower in non-asthmatic Israelis compared to non-asthmatic Anglo-Saxons.

Conclusions: The genetic distribution of ß₂AR polymorphisms in severe Israeli asthmatics is not different from that of non-asthmatic Israelis and therefore its clinical impact on asthma is probably minimal.
