Background: Fibroadema, one of the most common benign breast lesions, has a characteristic age-specific incidence and is associated with other pathological entities in 50% of cases. The clinical or imaging diagnosis of fibroadenoma may be erroneous, and in some cases is found to be invasive cancer. The clustering of such entities, their correlation with age, and the risk of synchronous breast malignancy are uncertain.

Objective: To explore the possibility of any sigficant clustering of fibroadenoma-associated benign breast disease and to assess the possible risk of concomitant breast cancer.

Method: We analyzed the pathological results of 147 women undergoing excisional biopsies for fibroadenoma diagnosed pre-operatively either by clinical examination and imaging (n=117) or by radiology alone (n=30). The inter-relationships among all entities associated with fibroadenoma were studies by hierarchial cluster analysis. The correlation of the various pathologies with the risk of invasive breast cancer in relation to the patient’s age was also evaluated.

Results: Fibroadema-associated pathologies were found in 48% of the cases: sclerosing adenosis (23%), duct ectasia (17/7%), apocrine metaplasia (15.6%), florid fibrocystic disease (12.9%), duct papillomatosis (11.6%), infiltrating duct carcinoma (5.4%), duct carcinoma in situ (3.4%), and 1 case of lobular carcinoma in situ (0.6%). An orderly internal hierarchy and three significant clusters emerged: a) epithelial apocrine metaplasia, duct ectasia and sclerosing adenosis (similarity coefficients 16.0, 11.0 and 8.0 respectively); b) papillomatosis, florid fibrocystic disease and calcifications (similarity coefficients of 6.0, 4.0 and 2.0 respectively); and c) infiltrating duct carcinoma in situ (similarity coefficients of 1.8 and 1.6 respectively). Seven of the eight patients with breast cancer were older than 40 years.

Conclusions: In about half of the cases fibroadema was associated with other pathological entities clustered in an orderly hierarchy. The rarity of synchronous breast cancer in the younger age group and its more common association with fibroadema in the older age groups dictate a different approach to each. The finding of fibroadema in women older than 40 indicates the need for surgical excision.

Background: Recent studies have suggested a possible association between Chlamydia pneumoniae infection and coronary heart disease.

Objectives: To determine titers of antibodies to Chlamydia pneumoniae in patients with acute  myocardial infraction compared with titers in several control groups.

Methods: This prospective case-control study investigated 209 individuals. We assessed the serum IgG antibody titers to Chlamydia pneumoniae in 57 consecutive patients admitted with AMI to our intensive coronary care unit during a 4 month period. A serum sample was drawn upon admission after 6 weeks. Results were compared with those of four control groups: a) patients admitted with community-acquired pneumonia (n=18), b) patients with community-acquired urinary tract infection (n=42), c) patients with angiographically normal coronary artery disease (n=44), and d) patients with stable coronary artery disease (n=48). Serum immunoglobin G antibody titers to C. pneumoniae were determined using standard micro-immunofluorescene technology.

Results: Of 57 patients with AMI, 32 (56%) had a high lgG titer to C. pneumoniae (>=1:256) on the initial test, which remained unchanged (62%) after 6 weeks. The percentage of patients with high titers was significantly lower in the control groups: 5 of 18 patients (28%) in the pneumonia group (P<0.01), 11 of 42 (26%) in the urinary tract infection group (P<0.01), 11 of 44 (25%) with normal coronary arteries (P<0.01), and 17 of 48 (35%) with stable chronic ischemic heart disease (P<0.05).

Conclusion: The detection of high titers of lgG antibodies to C. pneumoniae in many patients with AMI, compared to control groups, suggest that chronic Chlamydia pneumoniae infection plays a role in the pathogenesis of atherosclerosis and acute ischemic events.

Fibromyalgia syndrome is a chronic, painful musculoske­letal disorder of unknown etiology and/or pathophysiology. During the last decade many studies have suggested autonomic nervous system involvement in this syndrome, although contradictory results have been reported. This review focuses on studies of the autonomic nervous system in fibromyalgia syndrome and related disorders, such as chronic fatigue syndrome and irritable bowel syndrome on the one hand and anxiety disorder on the other, and highlights techniques of dynamic assessment of heart rate variability, It raises the potentially important prognostic implications of protracted autonomic dysfunction in patient populations with fibromyalgia and related disorders, especially for cardiovas­cular morbidity and mortality.

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: On 1 January 1995 a new mandatory National Health Insurance Law was enacted in Israel, The new law fostered competition among the four major Israeli healthcare providers (HMO5 or sick funds) already operating in the market due to the possibility that an unlimited number of patients and the relative budget share would shift among the HMOs. This led them to launch advertising campaigns to attract new members.

Objectives: To examine newspaper advertising activities during the early stages of healthcare market reform in Israel.

Methods: Advertising efforts were reviewed during a study period of 24 months (July 1994 to June 1996). Advertisements were analyzed in terms of marketing strategy, costs and quality of information.

Results: During the study period 412 newspaper adver­tisements were collected. The total advertising costs by all HMOs was approximately US$4 million in 1996 prices. Differences were found in marketing strategy, relative adver­tising costs, contents and priorities among the HMOs.

Conclusions: The content of HMO5 newspaper advertis­ing was consistent with their marketing strategy. The mes­sages met the criteria of persuasive advertising in that they cultivated interest in the HMOs but did not provide meaningful information about them. Future developments in this area should include consensus guidelines for advertising activities of HMOs in Israel, instruction concerning the content of messages, and standardization of criteria to report on HMO performance.

Background: Patients who feel involved in their treatment have better outcomes than those who do not.

Objective: To identify determinants of perceived patient involvement in obstetric care.

Methods: A retrospective study was undertaken in 1,452 (83%) of 1,750 women sampled in November 1995 from maternity wards of 14 general hospitals in Israel. A postal and telephone survey using a self-administered questionnaire included the following variables: hospital (identity number), patients' age, self-reported complications, previous deliveries, education, ethnicity, and number of obstetric interventions performed and/or considered. The main outcome measured was the reported involvement in decisions for obstetric interventions.

Results: Reported full involvement varied from 72% for epidural analgesia to 13% for forceps/vacuum extraction. Factor analysis identified two dimensions of perceived involvement: one for routine” interventions (enema, monitor­ing, IV line and episiotomy), which are performed in Israel mostly by midwives, and another for "special" interventions (forceps/vacuum extraction, epidural or other analgesia, and cesarian section) performed by physicians. Logistic regression identified hospitals, younger age, number of interventions, and Arab ethnicity as correlates of a perceived non-involvement in decisions for "special" interventions.

Conclusions: Clinical setting, age and ethnicity affected patient perception of involvement in decisions for obstetric interventions.

Background: Balneotherapy has been successfully used to treat various rheumatic diseases, but has only recently been evaluated for the treatment of fibromyalgia. Since no effective treatment exists for this common rheumatic disease, comple­mentary methods of treatment have been attempted.

Objectives:To assess the effectiveness of batneotherapy at the Dead Sea area in the treatment of patients suffering from both fibromyalgia and psoriatic arthritis.

Methods: Twenty-eight patients with psoriatic arthritis and fibromyalgia were treated with various modalities of bat­neotherapy at the Dead Sea area. Clinical indices assessed were duration of morning stiffness, number of active joints, a point count of 18 fibrositic tender points, and determination of the threshold of tenderness in nine fibrositic and in four control points using a dolorimeter.

Results: The number of active joints was reduced from 18.4+10.9 to 9+8.2 (P< 0.001). The number of tender points was reduced from 12.6+2 to 7.1±5 in men (P<0.003) and from 13.1+2 to 7.5+3.7 in women (P<0.001). A significant improvement was found in dolorimetric threshold readings after the treatment period in women (P< 0.001). No correlation was observed between the reduction in the number of active joints and the reduction in the number of tender points in the same patients (r= 0.2).

Conclusions: Balneotherapy at the Dead Sea area appears to produce a statistically significant substantial improvement in the number of active joints and tender points in both male and female patients with fibromyalgia and psoriatic arthritis. Further research is needed to elucidate the distinction between the benefits of staying at the Dead Sea area without balneotherapy and the effects of balneotherapy in the study population.

Background: Familial Mediterranean fever is a genetic disorder manifested by recurrent attacks of peritonitis, pleuritis and arthritis, and characterized by clinical, histological and laboratory evidence for localized and systemic inflammation. Colchicine treatment usually prevents the attacks and the associated inflammation. Inflammation of atherosclerosis and ischemic heart disease.

Objective: To study the effect of inflammation and its prevention on occurrence of IHD, using FMF as a model.

Methods and Patients: We studied the presence of IHD and its risk factors in 290 FMF patients aged 40 years or more, and in two control groups – 233 spouses of the FMF patients’ and 126 patients with inflammatory diseases obtained from other outpatient clinics. FMF patients were also compared with age and gender-matched individuals from the population reference data of the Israel Ministry of Health.

Results: The prevalence of IHD in FMF patients was significantly lower than in the group of controls from other outpatient clinics (15.5% vs. 30.2% P< 0.05) and comparable with their spouses (11.2%) and with the matched general population in Israel (16%).

Conclusion: These findings suggest that despite the evidence of recurrent inflammation, colchicines-treated FMF patients are not more predisposed to IHD than the normal population.

Background: The aim of family medicine is to provide patients with comprehensive care within the biopsychosocial model. High job satisfaction is necessary to attract physicians to this specialty

Objective: To compare job satisfaction levels between primary physicians with training in family medicine and physicians without specialty training.

Methods: A self-report questionnaire, the "Task Profiles of General Practitioners in Europe," was mailed to a stratified random sample of 664 primary care physicians in Israel. The response rate was 77.6%. Bivariate and logistic regression procedures were used to analyze the data.

Results: Physicians with training in family medicine were less satisfied with the rewards for their work than general practitioners with no formal specialization in family medicine. Satisfaction with the intrinsic aspects of the work was found to be equal. Women and rural physicians were more satisfied than men and urban physicians.

Conclusion: Measures should be taken by health maintenance organizations to increase the level of job satisfaction of specialist-certified family physicians to avoid a crisis in the profession.
