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.

Background: When encountering complaints of pain in the area of the Achilles tendon, the clinician seldom reaches a correct and precise diagnosis based solely on the grounds of physical examination and standard X-rays.

Objectives: To assess the usefulness of ultrasound in diagnosing pathologies of the Achilles tendon.

Methods: We conducted a retrospective review of patients presenting at our orthopedic clinics.

Results: Sonography was used to evaluate 41 patients with achillodynia. This modality enabled the diagnoses of 19 abnormal tendons (46%), peritendinous and other lesions a complete rupture in two patients (5%) a partial rupture of the Achilles tendon in 3 (7%) various degrees of calcification of the tendon in 7 (17%) and peritendinous lesions discerned by the tendon’s hypoechoic regions with disorganized arrange­ment of collagen fibrils in 4 patients (10%). Other lesions included tendonitis (3 patients, 7%), retrocalcaneal bursitis (3 patients, 7%), lipoma (1 patient, 2%), and foreign bodies (2 patients, 5%). The mean diameter of the pathological tendons was 10.4 +2.7 mm, while normal tendons measured 5.2 +0.8 mm (P<0.001).

Conclusion: As in many other soft tissue lesions, ultrasonography is a useful tool in the evaluation of the underlying pathology in patients presenting with achillodynia.

Background: Breast cancer is one of the most prevalent malignancies in women, yet one of the most treatable. Early detection is essential to obtain the desired remission and longevity. Numerous studies have shown that periodic screen­ing for breast cancer can reduce mortality by 20-30%.

Objective: To assess the rates, compliance, character­istics as well as barriers in women regarding mammography screening.

Methods: The study group comprised a random sample of 702 women aged 50 or older from 5914 eligible women in two teaching clinics in southern Israel. Phone interviews using structured questionnaires were conducted.

Results: The mean age of the study population was 61 years. The vast majority of the women were not born in Israel. Sixty-three percent of the women had undergone a mammo­graphy screening, 48% in the past 2 years. Monthly self-breast examinations were performed by 12% of the women in the last 2 years. Significant factors associated with undergoing mammography were: more than 7 years since immigration, married, a higher education level, adequate knowledge about breast cancer and mammography, presence of past or current cancer, and cancer in relatives. The main reasons for not being screened was no referral (54%) and a lack of knowledge about breast cancer and mammography (19%) - conditions easily remedied by physician counseling.

Conclusion: The study suggests that promotional efforts should be concentrated on new immigrants and on less educated and unmarried women.

Background: Complementary medicine incorporates several methods of treatment, all of which aim to promote the health and quality of life of the patient. Public interest and demand for complementary medicine services have increased in recent years in Israel, as they have throughout the western world.

Objective: To characterize patients attending the Com­plementary Medicine Clinic in southern Israel at the completion of its first 2 years of operation.

Methods: Data for 398 patients selected at random from 4,400 patients treated in the clinic were collected retroactively from the patientsq' charts.

Results: Of those who visited the clinic, 68% were women with an average age of 49 years. Patients attending the clinic had higher rates of hypertension (20%), diabetes (6%) and heart disease (7%) than the general population of patients insured at the Clalit Health Services in the southern region. In addition to musculoskeletal problems (47%), the other most common complaint was emotional problems (13%) such as tension and anxiety. Acupuncture and Shiatsu were the most commonly used types of treatment (61%). Homeopathy was used by 7%. Among patients with musculoskeletal problems, there were significantly more men than women (P= 0.02). The mean age was higher (P= 0.07). And more of them were referred by friends or family (P= 0.06) than those with other problems.

Conclusions: Characterizing patients attending a com­plementary medicine clinic is imporant for the planning of marketing and resource management, and can assist primary care physicians in decisions regarding the referral of patients to this type of healthcare.

Although a depressive state is known to occur following the resolution of an acute psychotic episode, little research has investigated its etiology, course, prognosis and treatment. Very often the depression is mistaken for an extrapyramidal­like syndrome — the secondary effect of antipsychotic medica­tion - as a sense of inevitability assails both the patient and therapist. Post-psychotic depression, far from being an obscure and undefined clinical picture, has the characteristics of a clear-cut syndrome. Nevertheless, it was only recently referred to as a distinct entity in psychiatric classification systems. As a result, different researchers used varying criteria for the definition of the phenomenon, and the data collected in the different studies are therefore difficult to compare. We present a critical review of the data published to date, with emphasis on the importance of early recognition and treatment of post-psychotic depression.

Background: It is not clear to what extent the drug economy in Israel's health maintenance organizations is responsive to major healthcare reforms.

Objective: To provide information on how drug expendi­tures, revenues, net costs and drug utilization have changed in the wake of the 1995 National Health Insurance Law in Israel.

Methods: This study compares trends in aggregate sick fund expenditures, revenues (patient co-payment) and net costs (expenditures less revenues) in Israel's four health maintenance organizations for the 3 year period 1992-1994 prior to the introduction in 1995 of the NHI Law, with that of the 4 year period 1995-1998 following its introduction. This analysis is similarly carried out for Israel’s largest HMO, Clalit Health Services, and for the three smaller HMOs combined.

Results: The pace of growth in the pre-NHI era in drug expenditures and particularly in drug revenues was drastically reduced in the NHI era - whether measured as totals or as per insured person (age-adjusted) or in real terms at constant medicine prices. These trends were mirrored to a large extent in

Conclusions: The impact of the NHI Law on the HMO drug economy has been substantial. The evidence suggests a decline in both the qualitative (basket of drugs consumed) and quantitative (volume of drugs consumed) elements of growth. These changes in expenditure and revenue trends are discussed in the light of the evolving involvement of the Israel Ministry of Health in drug policy within the framework of the NHI, with emphasis on the basket of drugs reimbursed and co­payments for prescriptions.

Objectives: To assess mortality causes and trends over time and identify target groups with excessive mortality rates among Israeli youth aged 10-24, in order to formulate an intervention policy for prevention of adolescent mortality.

Methods: Mortality data for Israeli residents aged 10-24 were extracted from the Central Bureau of Statistics compu­terized death certificate file for the period 1984-95. Trends were evaluated by cause of death and demographic char­acteristics.

Results: The crude mortality rate among Israeli youth aged 10-24, during 1993-1995, was 39.6 per 100000. Rates were 2.7 times higher among males, increased with age, and reached a peak among 18-21 year olds. Rates were 1.4 times higher among Arabs than among Jews. The sharp increase in mortality among Jewish males of military service age (18-21 years) was due mainly to motor vehicle crashes and suicide. Although overall mortality decreased by 9.4% from 1984-86 to 1993-95, the gap between the subgroups increased. MVC­related mortality increased over time by 100% among Arab males. The rate of completed suicide among Jewish males increased by 110%. Although injury-related mortality is lower in Israel compared with the U.S., similar demographic differen­tials and trends were found in both countries.

Conclusions: Suicide among Jewish males of military service age, as well as MVC fatalities among Arab males, present a growing public health issue. Intervention strategies should therefore be targeted towards these subgroups in order to minimize the rates of preventable death.

Background: Cryosurgery is a minimally invasive treat­ment option for prostate cancer.

Objectives: To report on the first series of cryosurgical ablation for prostate cancer performed in Israel.

Methods: Cryosurgical ablation of the prostate was undertaken in 2 patients aged 53-72 diagnosed with adenocarcinoma of the prostate. The procedures were performed percutaneously and were monitored by real-time trans-rectal ultrasound. The CRYOHIT machine applying Argon gas was used with standard or ultra-thin cryoprobes. The average follow-up was 12.8 months postsurgery (range 1- 24 months).

Results: No rectal or urethral injuries occurred and all patients were discharged from hospital within 24-48 hours. The duration of suprapubic drainage was 14 days in 10 patients and prolonged in 2. Early complications included penoscrotal edema in four patients, perineal hematoma in three, hemorrhoids in two and epidydimitis in one. Long-term complications included extensive prostatic sloughing in one patient and a perineal fistula in another, both of whom required prolonged suprapubic drainage. Minimal stress incontinence was noted in two patients for the first 8 weeks after surgery. None of the patients has yet regained spontaneous potency. A prostate-specific antigen nadir of less than 0.5 ng/ml was achieved in eight patients and an undetectable PSA level below 0.1 ng/ml in five patients.

Conclusion: Cryoablation for prostate cancer is safe and feasible, and the preliminary results are encouraging. Further study is needed to elucidate the efficacy of the procedure.

Background: Familial nephritis is a heterogeneous group of disorders caused by several genetic conditions such as Alport syndrome, glomerulonephritic syndromes, and unclas­sified nephritis without deafness or ocular defects.

Objectives: To describe a family of Iraqi Jewish origin, several of whose members suffer from non-syndromic renal failure without deafness or ocular defects and where transmis­sion is by autosomal dominant inheritance. We present the case histories of four family members and describe the molecular analysis performed in order to seek a possible linkage to one of the genes causing Alport or Alport-like syndromes.

Methods: We investigated all family members over the age of 18 for evidence of renal failure. We also extracted DNA and carried out molecular linkage analysis with polymorphic markers in each of the known loci involved in Alport and Alport­like syndromes.

Results: Histology of the renal biopsy specimens showed non-specific findings. Linkage was excluded for all the Alport and Alport-like syndrome loci.

Conclusions: The condition suffered by several members of this family seems to represent a unique autosomal dominant type of progressive hereditary nephritis, characterized by hypertension and progressive renal failure without significant hematuria or proteinuria. The main histological changes are non-specific in the early stage of the disease. Our study rules out all the currently known genes that cause Alport syndrome as being responsible for the basic defect in this type of nephritis.
