Background: Chronic obstructive pulmonary disease is an increasing cause of chronic morbidity and mortality around the world. The major cause of the disease is smoking. Despite the gravity of the problem there is no knowledge of its rate in the Israeli smoking population.

Objectives: To assess the prevalence of COPD[1]and early lung cancer among smokers.

Methods: People aged 45 up to 75 with a history of at least 20 pack-years cigarette smoking, including quitters, were screened for COPD. They were interviewed and a spirometry was performed.

Results: Of the 1150 people recruited 92% underwent and performed acceptable spirometry; 22% of these subjects had airflow limitation and were diagnosed with COPD according to the GOLD classification. Only 4% had been diagnosed as COPD prior to this screening. The majority of those tested were unaware of or unconcerned about developing the disease. There was no correlation between pack-years smoking and development of COPD, but there was a relative correlation of pack-years smoking and severity of COPD, particularly in the older group only (r = 0.42).

Conclusions: About one-fifth of the smokers aged 45 and up developed COPD. There is a significant gap between the disease distribution and its awareness in the population at risk. The need for a national screening program and early diagnosis of COPD in people at risk is needed.

Background: In an era of increasing antimicrobial resistance, knowledge of local antimicrobial susceptibility patterns of common uropathogens is essential for prudent empiric therapy of community-acquired urinary tract infections.

Objectives: To define antimicrobial susceptibility of Gram-negative uropathogens in northern Israel over a 10 year period and to compare it with antibiotic-use patterns in the same community.

Methods: We tested the susceptibility of all Gram-negative urinary isolates from outpatients at HaEmek Medical Center over the years 1995, 1999, 2002 and 2005 to common antimicrobial agents. MIC₉₀ of Escherichia coli to some of these agents was determined and antibiotic consumption data over the years 2000–2005 (DDD/1000/day) were obtained.

Results: We observed a rise in susceptibility rates of E. coli to amoxicillin-clavulanate, trimethoprim-sulfamethoxazole and nitrofurantoin and of other Gram-negative isolates to amoxicillin-clavulanate, ceftriaxone and cephalothin. Susceptibility rates of all Gram-negative uropathogens to ciprofloxacin decreased significantly. MIC₉₀ of E. coli for all drugs tested remained stable. There was a significant decrease in the use nitrofurantoin and TMP-SMX[1] and a significant increase in the use of ampicillin, cephalothin and ceftriaxone.

Conclusions: Antibiotic resistance patterns mostly remained unchanged or improved slightly. There was, however, a constant decrease in susceptibility of all Gram-negative uropathogens to ciprofloxacin. Antibiotic use patterns could not explain the changes seen in antibiotic susceptibility patterns.

Research findings have shown the protective effect of religiosity – among both Christians and Israeli Jews – in terms of morbidity and mortality. To explore the relationship between religiosity and health behavior as a possible explanation for these findings we conducted 3056 telephone interviews, representing the Israeli adult urban Jewish population. Health status, health behavior, frequency of medical checkups, and eating habits were measured. Logistic regressions were used to estimate the religiosity gradient on health behavior, controlling for other personal characteristics. We found a lower prevalence of stress and smoking among religious persons; we also found that religious women exercise less than secular women and that religious people – both men and women – are more obese than their secular counterparts. While no religiosity gradient was found with relation to the frequency of blood pressure, cholesterol and dental checkups, religious women are less likely to undergo breast examinations and mammography. Finally, religious people generally follow a healthier dietary regime, consuming less meat, dairy products and coffee, and much more fish. The lower smoking rates, lower levels of stress, and the healthier dietary regime are consistent with the previously shown longer life expectancy of religious people; however, obesity might become a risk factor in this community.

Background: With the development of computer technology and the high-tech electronic industry over the past 30 years, the technological age is flourishing. New technologies are continually being introduced, but questions regarding the economic viability of these technologies should be addressed.

Objectives: To identify the medical technologies that are currently in use in different rehabilitation medicine settings in Israel

Methods: The TECHNO-R 2005 survey was conducted in two phases. Beginning in 2004, the first survey used a questionnaire with open questions relating to the different technologies in clinical use, including questions on their purpose, who operates the device (technician, physiotherapist, occupational therapist, physician, etc.), and a description of the treated patients. This questionnaire was sent to 31 rehabilitation medicine facilities in Israel. Due to difficulties in comprehension of the term “technology,” a second revised standardized questionnaire with closed-ended questions specifying diverse technologies was introduced in 2005. The responder had to mark from a list of 15 different medical technologies which were in use in his or her facility, as well as their purpose, who operates the device, and a description of the treated patients.

Results: Transcutaneous electrical nerve stimulation, the TILT bed, continuous passive movement, and therapeutic ultrasound were the most widely used technologies in rehabilitation medicine facilities. Monitoring of the sitting position in the wheelchair, at the bottom of the list, was found to be the least used technology (with 15.4% occurrence). Most of the technologies are used primarily for treatment purposes and to a lesser degree for diagnosis and research.

Conclusions: Our study poses a fundamental semantic and conceptual question regarding what kind of technologies are or should be part of the standard equipment of any accredited rehabilitation medicine facility for assessment, treatment and/or research. For this purpose, additional data are needed.
 

Background: Trauma management includes the care provided both in hospital and by emergency medical systems in the community. In many cases it is the parents who decide where to take an injured child for care, depending on the circumstances and severity of the injury, the personal characteristics of the injured or the carer and the availability and accessibility of services.

Objectives: To examine the use of pre-hospitalization services and reasons for their use by children and adolescents according to the injury and personal characteristics.

Methods: The study group comprised 924 Israeli citizens aged 0–17 years hospitalized for injuries in six hospitals across Israel. Carers were interviewed in the hospital regarding the circumstances of the injury event, the use of pre-hospitalization services, and sociodemographic characteristics. Data on the cause and nature of the injury were obtained from the hospital records.

Results: The proportion of severe injuries (Injury Severity Score 16+) was higher in Arab children than Jewish children (15% and 9% respectively). Sixty-three percent of the Arab children and 39% of the Jewish children used community services prior to hospitalization. The odds ratio of proceeding directly to the hospital was 0.44, 95% confidence interval 0.29–0.69, for the Arab compared to the Jewish children, controlling for severity, cause and nature of the injury, sociodemographic characteristics, and the reported availability of ambulance services.

Conclusions: More Arab than Jewish carers tended to seek care in the community for an injured child, but the effect of personal characteristics on seeking care was similar in both population groups. Issues of availability and accessibility of services may explain the differences.

Background: Smoking continues to be the most significant preventable  cause of morbidity and early mortality in the developed world. Primary care physicians are not fufilling their potentially vital and effective role regarding tobacco use and dependence.

Objectives: To evaluate current primary care physician practise in promoting smoking cessation.

Methods: This observational study evaluated physician recording of smoking status by analysis of patients’ electronic medical records. The 126 primary care physicians were based in 23 Tel Aviv clinics treating 144, 811 patients. We also assessed additional physician anti-smoking activities by telephone questionnaire of 178 randomly selected patients.

Results: Analysis of the EMRs[1] revealed that an average of 4.4% of patients per physician were recorded as smokers (as compared to a known smoking rate in this patient population of 24%). Male physicians recorded a significantly higher proportion of their patients as smokers in the EMR compared to female physicians (P < 0.05). A non-significantly higher rate of recording smokers was found in doctors who had completed postgraduate specialization in family medicine as compared to non-specialists. The questionnaire results show that 41% of patients interviewed recalled being asked if they smoked and 31% of smoking patients had been advised to quit. A non-significantly higher proportion of male as compared to female patients reported being questioned if they smoked, and if they were smokers, being advised to quit.

Conclusions: This study shows low rates of physician intervention to promote smoking cessation. It appears that a large proportion of the primary care physicians surveyed do not follow recommendations to promote smoking cessation among their patients. Intervention among adolesent smokers was particularly inadequate. Further action is needed to improve the performance of physicians in aiding smoking cessation.

Background: A paradoxical secular trend of an increase in preterm births and a decrease in low birth weights has been reported in many developed countries over the last 25 years.

Objective: To determine if this trend is true for Israeli neonates, and to add new information on secular trends in crown-heel length and head circumference.

Methods: A hospital-based historic cohort design was used. Anthropometric data for 32,062 infants born at Rabin Medical Center in 1986–1987, 1994–1996, and 2003–2004 were collected from the hospital’s computerized registry and compared over time for absolute values and proportional trends.

Results: For the whole sample (gestational age 24–44 weeks) there was a significant increase in mean birth weight (by 41 g), crown-heel length (by 1.3 cm), and head circumference (by 0.1 cm) from 1986 to 2004 (P < 0.001). A similar trend was found on separate analysis of the post-term babies. Term infants showed an increase in mean length and head circumference (P < 0.001), but not weight, and moderately preterm infants (33–36 weeks) showed an increase in mean weight (81 g, P < 0.001) and mean length (1.0 cm, P < 0.001), but not head circumference. The proportion of post-term (42–44 weeks), preterm (24–36 weeks), very preterm (29–32 weeks), extremely preterm (24–28 weeks), low birth weight (< 2500 g) and very low birth weight (< 1500 g) infants decreased steadily and significantly over time (P < 0.002).

Conclusions: Babies born in our facility, term and preterm, are getting bigger and taller. This increase is apparently associated with a drop (not a rise) in the proportion of preterm infants. These results might reflect improvements in antenatal care and maternal determinants.
 

Background: Age-related macular degeneration is the most common cause of legal blindness in the developed world including Israel. Ethnic background is a risk factor for advanced AMD[1] in several populations, however the relative prevalence of this disease in different ethnic groups in the Middle East is unknown.

Objectives: To compare the prevalence of advanced AMD in Arabs and Jews in Israel.

Methods: We performed a retrospective analysis of two independent groups of patients: the first group comprised a sequential series of Jerusalem residents who underwent photodynamic therapy for neovascular AMD (PDT[2] group), and the second group consisted of all individuals in Jerusalem who received a blind certificate due to AMD (legal blindness group). Control groups were assessed to exclude inherited ethnic associated bias in the two study groups.

Results: The PDT group included 146 patients: 142 were Jews (97.3%) and 4 were Arabs (2.7%). The legal blindness group included 340 Jerusalem residents: 326 Jews (96%) and 14 Arabs (4%). The number of Arab AMD patients in the two groups was lower than expected based on the ethnic composition of the age-matched Jerusalem population (P = 0.0002 for the PDT group, and P < 0.0001 for the legal blindness group). By contrast, the number of non-AMD Arab patients who were treated in the same clinic and the number of Arabs who received a blind certificate for diabetic retinopathy was not different from expected based on their relative number in the Jerusalem population.

Conclusions: Advanced AMD is less common in the Arab than the Jewish population of Jerusalem. Genetic and environmental factors may account for this difference. A population-based study is required to assess the overall prevalence of AMD in Jews and Arabs.

Background: Burns are a major public health problem, with long hospitalization stay in both intensive care units and general wards. In Israel about 5% of all hospitalized injuries are burn injuries. There are no long-term epidemiological studies on burn injuries in adults in Israel.

Objectives: To identify risk factors for burn injuries and provide a starting point for the establishment of an effective prevention plan.

Methods: We analyzed the demographic, etiologic and clinical data of 5000 burn patients admitted to the five major hospitals with burn units in Israel during a 7 year period (1997–2003). Data were obtained from the records of the Israeli National Trauma Registry. The differences between various groups were evaluated using the chi-square test.

Results: Male gender was twice as frequent as female gender in burn patients (68.0% vs. 31.9%), and Jewish ethnicity was more common than non-Jewish (62.3% vs. 36.8%). Second and third-degree burns with body surface areas less than 10% constituted the largest group (around 50%). The largest age group was 0–1 years, constituting 22.2% of the cases. Inhalation injury was uncommon (1.9%). The most common etiologies were hot liquids (45.8%) and open fire (27.5%). Children less than 10 years old were burnt mainly by hot liquids while the main cause of burns for adults > 20 years old was an open flame. The majority of burns occurred at home (58%); around 15% were work related. The mean duration of hospitalization was 13.7 days (SD 17.7); 15.5% were in an intensive care unit with a mean duration of 12.1 days (SD 17.1). Surgical procedures became more common during the period of the study (from 13.4% in 1998 to 26.59% in 2002, average 19.8%). The mortality rate was 4.4%. We found a strong correlation between burn degree and total body surface area and mortality (0.25% mortality for 2nd to 3rd-degree burns with less than 10% TBSA[1], 5.4% for 2nd to 3rd-degree burns with 20–39% TBSA, and 96.6% for burns > 90% TBSA). The worst prognosis was for those over the age of 70 (mortality rate 35.3%) and the best prognosis was for the 0–1 year group (survival rate 99.6%).

Conclusions: The groups at highest risk were children 0–1 years old, males and non-Jews (the incidence rate among non-Jews was 1.5 times higher than their share in the general population). Those with the highest mortality rate were victims of burns > 90% TBSA and patients older than 70. Most burns occurred at home.

Background: Serology of amebiasis is affected by low sensitivity and specificity.

Objectives: To evaluate the advantage of the indirect hemagglutination assay and enzyme-linked immunosorbent assay in the diagnosis of amebiasis, using Entamoeba histolytica soluble antigen (macerated amebic antigens) prepared from four different virulent isolates, continuously cultivated in the presence of the original enteric bacteria.

Methods: Using IHA[1] and ELISA[2] with MAA[3] antigen we examined 147 sera samples from patients with gastrointestinal symptoms, and 11 sera from amebiasis cases (confirmed by microscopy and copro-antigen ELISA ).

Results: Of 104 of the 147 (70.7%) symptomatic cases that were amebiasis positive by IHA, 81 (55.1%) were positive by MAA-ELISA. In addition, of 11 amebiasis cases confirmed by microscopy and copro-antigen ELISA , 7 (64%) were amebiasis positive by both tests. Four species of bacteria were isolated from the ameba cultures: Escherichia coli, Morganella morganii, Proteus mirabilis, and Streptococcus lactis. Elimination of the bacteria from the cultures by an antibiotics cocktail containing gentamicin, imipenem, piperacillin-tazobactam and vancomycin was the preferred method. Absorption of patients' sera to bacterial antigen prior to serological analysis had only a marginal effect.

Conclusions: These results indicate a correlation of 61% between the ELISA developed in this study and the IHA tests in the diagnosis of amebiasis.

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.
