Background: The rate of trauma in the elderly is growing.

Objectives: To evaluate the characteristics of non-hip fracture-associated trauma in elderly patients at a level I trauma center.

Methods: The study database of this retrospective cohort study was the trauma registry of a level I trauma center. Trauma patients admitted from January 2001 to December 2003 were stratified into different age groups. Patients with the diagnosis of hip fracture were excluded.

Results: The study group comprised 7629 patients. The non-hip fracture elderly group consisted of 1067 patients, 63.3% women and 36.7% men. The predominant mechanism of injury was falls (70.5%) and most of the injuries were blunt (94.1%). Injury Severity Score was found to increase significantly with age. The average mortality rate among the elderly was 6.1%. Age, ISS[1], Glasgow Coma Score on admission, and systolic blood pressure on admission were found to be independent predictors of mortality.

Conclusions: Falls remain the predominant cause of injury in the elderly. Since risk factors for mortality can be identified, an effective community prevention program can help combat the future expected increase in morbidity and mortality associated with trauma in the elderly.

Objective: To study the attitude of physicians to obesity by examining discharge letters of overweight patients with ischemic heart disease.

Methods: We used the HOLEM database for this analysis. The HOLEM project was designed to study the NCEP (National Cholesterol Education Program) guideline implementation among patients with IHD[1] at hospital discharge. We documented the recording of risk factors and treatment recommendations for IHD by reviewing the discharge letters of 2994 IHD patients admitted to four central hospitals in Israel between 1998 and 2000. A follow-up visit was held 6–8 weeks after discharge, at which time the diagnosis of IHD was verified, risk factor status was checked, height and weight were measured and drug treatment was reviewed.

Results: Mean body mass index was 28.3 kg/m² and 32% were obese (BMI[2] ³ 30 kg/m²). Only 39.6% of the obese patients and 65.8% of the morbidly obese patients (BMI ³ 40 kg/m²) had "obesity" noted in their discharging letters, and weight loss recommendation was written in only 15% of the obese patients' discharge letters. Acute episodes like acute myocardial infarction and unstable angina did not influence the notation of obesity, and only BMI and the number of additional risk factors were positively correlated with the notation of this risk factor.

Conclusions: Despite the importance of obesity, weight status was not noted and weight loss was not recommended in most of the discharge letters of obese IHD patients.

Background: The contribution of drugs and alcohol to current trauma‑related morbidity and mortality in Israel is not known. Identification of these factors in the fast-changing demographics of the Israeli population might lead to better care and, no less importantly, to targeted prevention measures.

Objectives: To determine the incidence of alcohol‑related trauma, and to specify the time of day, the cause of trauma, and the morbidity and mortality rates as compared to non-alcohol‑associated trauma in the tertiary trauma unit of a large medical center in Tel Aviv.

Methods: Data were obtained from the Israel National Trauma Registry, based on patient records in our institution (Tel Aviv Sourasky Medical Center) from January 2001 to December 2003.

Results: Of the 5,529 patients who were enrolled in the study, 170 had high alcohol blood levels (> 50 mg/dl). Patients intoxicated with alcohol had higher rates of road accident injuries (35% versus 24% non‑intoxicated) and stab wounds (29% vs. 7%). The Injury Severity Score of the alcohol‑intoxicated patients was higher (32% ³ 16 vs. 12% ³ 16). The alcohol‑intoxicated patients were more likely to be non-Jewish (34% vs. 9%), young (82% aged 15–44 years) and males (91%). Most of the alcohol‑related injuries occurred during the weekend (47%) and during evening‑late night hours (from 7 a.m. to 11 p.m.; 55%).

Conclusions: Alcohol‑associated trauma differs from non-alcohol‑associated trauma in many ways. Since the population at risk can be identified, it is important that legislative, social, enforcement and educational measures be adopted to reduce the extent of alcohol abuse and thereby improve the level of public safety.
 

Epidemiologic data demonstrate a long-linear realationship between low density lipoprotein-cholesterol levels and risk of coronary heart disease.

Objectives: To examine whether the treatment recommendations given to ischemic heart disease patients at hospital discharge are compatible with the guidelines of the Israeli Medical Societies and the U.S. National Cholesterol Education Program for coronary artery disease prevention; and to study the effects of brief educational sessions on the adherence of physicians with the guidelines.

Methods: We included consecutive IHD[1] patients admitted to four central hospitals in Israel between 1998 and 2000. The study was conducted in two phases. In phase 1, we reviewed discharge letters to document treatment recommendations given to each patient. In phase 2 we educated the practitioners by reviewing the Israeli Medical Societies and the NCEP[2] guidelines and the quality of their recommendations in phase 1, after which we reevaluated the discharge letters.

Results: The study included 2,994 patients: 627 in phase 1 and 2,367 in phase 2. Of the patients who needed cholesterol-lowering according to their low density lipoprotein levels, 37.4% were not prescribed such drugs at discharge (under-treatment group). This proportion was reduced by education to 26.6% (P < 0.001) in phase 2. Of the treated patients, 65.6% did not reach the target LDL[3] goal in phase 1 (under-dosage group) as compared to 60.2% in phase 2 (P = 0.23). In phase 2 there was an increase in the percent of patients reaching LDL levels <130 mg/day (69.3% vs. 63.8% of patients prescribed medication, P = 0.01), but the percent of patients reaching LDL levels <100 was not different in phase 2 after adjusting for age and gender (the odds ratio for reaching target LDL was 1.16, with 95% confidence interval of 0.95–1.43).

Conclusions: Physician recommendations to IHD patients discharged from hospital were suboptimal. We documented a high proportion of under-treated and under-dosage patients. Brief educational sessions have a beneficial effect on the usage of statins; however, additional effort in guideline implementations is needed.

Objectives: To assess the effect of a vaginal ring delivering estradiol and progesterone in postmenopausal women and to determine whether continuous administration can relieve climacteric symptoms, produce an acceptable pattern of vaginal bleeding and control endometrial proliferation.

Methods: Twenty-nine postmenopausal women with an intact uterus were studied. All had climacteric symptoms. The vaginal rings contained 0.36 g estradiol and either 3.6 g progesterone (high dose progesterone) or 1.8 g (low dose progesterone), and were kept in place for 4–6 months. Serum progesterone, estradiol and estrone were measured and endometrial thickness determined. All women kept a daily diary of bleeding/spotting and completed a questionnaire on climacteric symptoms at monthly intervals. The low dose progesterone group comprised 14 women and the high dose progesterone group 15 women.

Results: A total of 18 patients (9 in each group) completed the study. Mean levels of estradiol, estrone and progesterone were at their peak after 2 to 4 weeks. All rings were effective in alleviating vasomotor symptoms, although there was evidence of the "escape from effect" in month 6. Endometrial thickness increased in 6 of the 29 women but biopsy in each case showed no evidence of hyperplasia. Of the 18 women who completed the study, 5 had amenorrhea throughout, 7 had amenorrhea after 3 months, and the remainder had one or two bleeding episodes after 3 months. Therapy was discontinued in 11 women.

Conclusions: A vaginal ring delivering estradiol and progesterone controlled climacteric symptoms, prevented endometrial proliferation, and provided an acceptable bleeding pattern. It should be viewed as a promising alternative for short-term estrogen-progesterone therapy.

Objectives: To describe and analyze how PCPs[1] in the IDF[2] view their roles as primary care providers and to characterize how they perceive the quality of the medical care that they provide.

Methods: We conducted a survey using a questionnaire that was mailed or faxed to a representative sample of PCPs. The questionnaire included demographic background, professional background, statements on self-perception issues, and ranking of roles as a PCP in the IDF.

Results: Statements concerning commitment to the patient were ranked higher than statements concerning commitment to the military organization. Most physicians perceive the quality of the medical care service that they provide as high; they also stated that they do not receive adequate continuous medical education.

Conclusions: Our survey shows that PCPs in the IDF, like civilian family physicians, perceive their primary obligation as serving the needs of their patients but are yet to take on the full role of “gatekeepers” in the IDF’s healthcare system. We conclude that the Medical Corps should implement appropriate steps to ensure that PCPs are prepared to take on a more prominent role as “gatekeepers” and providers of high quality primary medical care.

Background: Oral contraceptive users are at increased risk for both arterial and venous thrombosis, some of which can be fatal. Studies are consistent with the existence of a synergism between cigarette smoking and OC[1] use in the pathogenesis of myocardial infarction in young women.

Objectives: To study the relationship between OC use, cigarette smoking and other cardiovascular risk factors among young women.

Methods: A systematic sample of military personnel, upon discharge from service in the Israel Defense Forces, was asked to complete a research questionnaire. Body weight and height were measured and body mass index computed.

Results: Overall, 16,258 questionnaires were collected and analyzed during this 20 year study. There was a gradual, significant increase in OC use until the mid-1980s, from approximately 45% to 60% (P < 0.001), followed by steady rates of 58–64% since then. In contrast, the rates of smoking decreased significantly in the mid-1980s, from approximately 42% to a nadir of 22% in 1991. Since then, the rate of smoking has increased slowly but steadily, to reach a level of 35% in 1999. The OC users were more often of western (Ashkenazi) origin and came from families with more education and fewer siblings. They were more often smokers than non-OC users, and started smoking at a younger age. They had significantly lower BMI[2] than non-users. OC use was nearly identical in groups with or without multiple cardiovascular risk factors (smoking, obesity, family history).

Conclusions: Smoking and OC use are strongly associated. Other cardiovascular risk factors (smoking, obesity, family history) do not prevent OC users from smoking or smokers to use OC. We suggest that primary care physicians discourage smoking among adolescent females who wish to start using OC. A thorough medical history should be obtained to recognize all risk factors for cardiovascular disease and to provide for appropriate contraception counseling.

Background: Increased serum potassium and intraventricular hemorrhage occur frequently in preterm infants.

Objective: To retrospectively analyze data obtained on infants with severe IVH[1] in relation to blood K⁺ concentrations.

Methods: We identified all patients with severe IVH born between July 1997 and July 2000. Each patient was pair-matched with a control infant of the same gestational age (±1 week) without IVH in terms of head ultrasound findings on day 5, and whole blood K⁺ on days 3–5.

Results: There were 24 infants in each group. The IVH group had significantly lower 1 minute Apgar scores and pH and higher blood K⁺ than the control group. Blood pH and K⁺ were inversely correlated. Stepwise regression analysis, taking into account blood pH and 1 minute Apgar score, showed a correlation only between blood K⁺ and IVH status.

Conclusions: Severe IVH is significantly associated with higher blood K⁺ concentrations. A causal relationship cannot be ascertained at this point.

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.

Background: The Israeli Blood Pressure Control program was initiated to enhance the control of modifiable risk factors among high risk hypertensive patients followed by general practitioners in Israel.

Objective: To report the baseline results of the state of the treatment regarding blood pressure management, lipid and glucose control as well as obesity and smoking cessation among the patients.

Methods: Hypertensive patients were screened in 30 general practice clinics supervised by family medicine specialists seeing 1,000–5,000 patients each. Between 50 and 250 hypertensive patients were diagnosed at each participating clinic. Blood pressure levels, body mass index, lipid and glucose levels, as well as target organ damage and medications were recorded for all patients.

Results: Of the 4,948 patients registered, 2,079 were males (42%). Mean age was 64.8 ± 12. Blood pressure control was achieved in only 33.1% of total hypertensive patients. Low density lipoprotein control was achieved in 31.1% of all patients, and glucose control in only 28.5%% of diabetic patients (glucose < 126 mg/dl); 20.7% of the diabetics had glucose levels above 200 mg/dl. In this group of patients 38.9% were obese (BMI[1] >30 kg/m²). While there were more obese females than males (48.0% vs. 35.6%), no difference was found in blood pressure, lipid or glucose control between the genders.

Conclusion: Risk factor management of hypertensive patients attending general practice clinics in Israel is not optimal, especially among those with diabetes or in need of secondary prevention measures. A long-term intervention program for high risk patients in the community is needed to improve the current situation.
