Background: The implementation of treatment guidelines is lacking worldwide.

Objectives: To examine whether follow-up in a specialized lipid clinic improves the achievement rate of the treatment guidelines, as formulated by the National Cholesterol Education Program and the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.

Methods: The study group included patients who were referred to the lipid clinic because of hyperlipidemia. At each of five visits over a 12 month period, lipid levels, liver and creatine kinase levels, body mass index, and adherence to diet and medications were measured, and achievement of the NCEP[1] target level was assessed.

Results: A total of 1,133 patients (mean age 61.3 years, 60% males) were studied. Additional risk factors for atherosclerosis included hypertension (41%), type II diabetes mellitus (21%), smoking (17%), and a positive family history of coronary artery disease (32%). All patients had evidence of atherosclerotic vascular disease (coronary, cerebrovascular or peripheral vascular diseases). The low density lipoprotein target of <100 mg was present in only 22% of patients before enrollment, with improvement of up to 57% after the follow-up period. During follow-up, blood pressure control was improved (from 38% at the time of referral to 88% after 12 months, P < 0.001), as was glycemic control in diabetic patients (HgA1C improved from 8.2% to 7.1% after 12 months, P < 0.001). Improved risk factor control was due to increased compliance to medication treatment (from 66% at enrollment to more than 90% after 12 months), as well as careful attention to risk factor management that translated into a change in the treatment profile during the follow-up. There was an increase in the use of the following medications: aspirin from 68% to 96%, statins from 42% to 88%, beta blockers from 20% to 40%, and angiotensin-converting enzyme inhibitors from 28% to 42%; while calcium channel blocker use decreased from 40% to 30% in patients during follow-up.

Conclusion: Follow-up of patients in a specialized clinic enhances the achievement of LDL[2]-cholesterol treatment goals as well as other risk factor treatment goals, due to increased patient compliance and increased use of medications.

Background: Patients with multivessel coronary artery disease are candidates for either angioplasty and stenting or coronary artery bypass grafting. A prospective randomized study designed to compare the both methods included only a minority of the eligible patients.

Objective: To compare coronary artery bypass grafting to angioplasty plus stenting in patients with multivessel disease who declined randomization to a multicenter study (the ARTS).

Methods: During 1997-98 we prospectively followed 96 consecutive patients who were eligible according to the ARTS criteria but refused randomization. Of these patients, 50 underwent angioplasty + stenting and 46 underwent coronary bypass surgery. We compared the incidence of major adverse cardiac and cerebral events, chest pain recurrence, quality of life and procedural cost during the first 6 months.

Results: All procedures were completed successfully without mortality or cerebral events. The rate of Q-wave myocardial infarction was 2% in the AS[1] group vs. 0% in the CABG[2] group (not significant). Minor complications occurred in 7 patients (14%) in the AS group and in 21 patients (45%) in the CABG group (P < 0.01). At 6 months follow-up the incidence of major cardiac and cerebral events was similar in both groups (11% and 4% in the AS and CABG groups respectively, P=NS). Seventeen patients (36%) in the AS group required repeat revascularization compared to only 3 (7%) in the CABG group (P=0.002). Nevertheless, quality of life was better, hospitalization was shorter and the cost was lower during the first 6 months after angioplasty.

Conclusion: Angioplasty with stenting compared to coronary bypass surgery in patients with multivessel disease resulted in similar short-term major complications. However, 36% of patients undergoing angioplasty may need further revascularization procedures during the first 6 months.

Background: The most frequent cause of defect in the mandible is tumor-related surgery. Larger defects or anterior arch defects cause severe morbidity due to disturbances in function and aesthetics.

Objectives: To assess the outcome of free tissue transfer for mandible reconstruction.

Methods: Since 1998 we operated on 11 patients with mandible defects using the fibula flap as the reconstruction method. We performed immediate reconstruction in eight patients after ablative surgery, and late reconstruction due to radiation-induced complications in three.

Results: All patients achieved good functional and aesthetic outcome. During the follow-up period two patients died of their malignant disease and one patient died from a non-related cause. Although two patients underwent reoperation in the first 3 months after their primary operation due to fixation failure, there were no other major complications.

Conclusions: According to the literature and our limited experience, the fibula flap is a safe and reliable option for mandible reconstruction.

Background: Femoral hip fractures are a common occurrence in the elderly. Of the various fracture patterns, intertrochanteric injuries have the lowest rate of complications. Case reports of ensuing subcapital fracture have all been linked to incorrect placement of fixation devices or to osteomyelitis, while cases of avascular necrosis have only been reported rarely in the literature and are considered to occur at the rare rate of 0.8%.

Objectives: To check the incidence and outcome of AVN[1] in intertrochanteric hip fractures.

Methods and Results: In a retrospective analysis of patients who had surgical treatment for intertrochanteric fractures, 10 patients (0.5%) underwent dynamic hip screw fixation for intertrochanteric fractures and subsequently developed painful AVN as their primary presentation. Three of these patients were also found to have subcapital fractures. On revision of the primary fixation no fault was found with nail placement.

Conclusions: The reported rate of AVN may be understated since many patients have limiting factors that prevent them from consulting a physician when in pain, and one-third of these patients die within 2 years. Therefore, we suggest that hip pain following fixation of an intertrochanteric fracture should prompt the clinician to consider the rare possibility of AVN or subcapital fracture.

Background: The importance of health promotion and disease prevention in health policy and clinical practice is widely accepted in many countries. However, a large number of medical schools do not dedicate a significant part of their curriculum to these aspects. In Israel, there are no reports on the training of the future physician towards his or her role as health promoter in general, or in the areas of cardiovascular and cancer diseases specifically.

Objectives: To examine the preparation of Israel medical students for the role of health promoter in cancer and cardiovascular diseases.

Methods: The study was carried out over 2 years in two of the four medical schools in Israel: the Sackler Faculty of Medicine at Tel Aviv University and the Faculty of Health Sciences at Ben Gurion University in Beer Sheva. The students (n=172, 70% response rate) were surveyed during 1999-2000 by means of a questionnaire, which included assessment of their training towards the role of health promoter, their clinical experiences and exposure to patients at different stages of illnesses at various medical sites, and the specific skills and relevant knowledge they acquired.

Results: Most of the students’ learning experiences occurred in hospitals with patients at the treatment stage and little time was dedicated to prevention, especially in the community. They demonstrated better knowledge, skills and satisfaction with their learning experiences in CVD than in cancer; and reported having insufficient exposure to several common cancer diseases and lacking examining skills for early detection of cancer. The students in Beer Sheva had significantly more interaction with patients at different stages of CVD and acquired more examination skills than the Tel Aviv students.

Conclusions: A change in the curriculum is urgently needed: namely training medical students in community settings and preparing them to promote the well-being of their patients, including prevention. Attention should be given to launching new learning modes in the pre-clinical and clinical curriculum. We propose that: a) pre-clinical courses include prevention techniques in CVD and cancer, problems of cancer patients, and some examining skills; and b) the clinical phase should integrate oncology concepts and total cancer and CVD care into existing clerkships in the hospitals and in the community.

Background: Fixed dose combination therapy varies among countries.

Objective
: To compare the list of fixed-dose combination therapies used in the USA, UK and Israel.

Methods:
The total list of drugs and FDC drugs were counted manually from a list of generic names. We also counted the number of drugs in four characteristic subgroups:

cardiovascular, anti-infective, gastrointestinal, and dermatolo­gical. Data for drugs in the USA, UK and Israel were taken from the Physician’s Desk Reference (PDR 1997), the British National Formulary (BNF March 1997) and the Monthly Ethical Drug Indexed Compilation (MEDIC July 1997) respectively.

Results:
The global percentage of FDC drugs in the USA and UK was higher than in Israel (20%, 25% and 15% respectively). A similar trend was found in all subclasses of FDC drugs except for the anti-infective category in which the percentage of FDC drugs was low and similar in all countries.

Conclusion: 
The list of FDC drugs varies greatly between the USA, UK and Israel. reflecting the differences in the outcome of debate between the pharmaceutical companies and the regulatory authorities.
