Background: Current clinical guidelines restrict catheterization laboratory activity without on-site surgical backup. Recent improvements in technical equipment and pharmacologic adjunctive therapy increase the safety margins of diagnostic and therapeutic cardiac catheterization.

Objective: To analyze the reasons for urgent cardiac surgery and mortality in the different phases of our laboratory’s activity in the last 11 years, and examine the impact of the new interventional and therapeutic modalities on the current need for on-site cardiac surgical backup.

Methods: We retrospectively reviewed the mortality and need for urgent cardiac surgery (up to 12 hours post-catheterization) through five phases of our laboratory’s activity: a) diagnostic (years 1989–2000), b) valvuloplasties and other non-coronary interventions (1990–2000), c) percutaneous-only balloon angioplasty (1992–1994), d) coronary stenting (1994–2000), and e) use of IIb/IIIa antagonists and thienopiridine drugs (1996–2000).

Results: Forty-eight patients (0.45%) required urgent cardiac surgery during phase 1, of whom 40 (83%) had acute coronary syndromes with left main coronary artery stenosis or the equivalent, and 8 (17%) had mechanical complications of acute myocardial infarction. Two patients died (0.02%) during diagnostic procedures. In phase 2, eight patients (2.9%) were referred for urgent cardiac surgery due to either cardiac tamponade or severe mitral regurgitation, and two patients (0.7%) died. The combined need for urgent surgery and mortality was significantly lower in phase 4 plus 5 as compared to phase 3 (3% vs. 0.85%, P = 0.006).

Conclusion: In the current era using coronary stents and potent antithrombotic drugs, after gaining experience and crossing the learning curve limits, complex cardiac therapeutic interventions can safely be performed without on-site surgical backup.
 

Background: Developments in laparoscopic surgery have rendered it an efficient tool for many complex surgical procedures. In the last few years, laparoscopic adrenalectomy has become a more viable option for removal of adrenal pathology, with many surgeons preferring it to the conventional open technique.

Objectives: To describe the indications, technique, complications and follow-up of patients undergoing laparoscopic adrenalectomy in our department.

Methods: The hospital files of 30 patients who underwent the procedure were reviewed. There were 19 females and 11 males with a mean age of 45 years. Indications for surgery differed and included hypersecreting adenoma, pheochromocytoma, suspected malignancy, and incidentaloma.

Results: Of the 31 laparoscopic adrenalectomies performed, 11 were right, 18 were left, and 1 was bilateral. The conversion rate to an open procedure was 3%. The mean duration of procedure was 120 minutes. Only one patient required blood transfusion. Complications occurred in 20% of patients, all reversible. There was no mortality. Mean hospitalization duration was 3.4 days, and median follow-up 17 months. There were no late complications. All patients operated on for benign diseases are alive.

Conclusions: Laparoscopic adrenalectomy appears to be a useful tool for the treatment of a range of adrenal pathologies.

Background: Fractures of the stemum may be associated with major injuries to thoracic organs, with serious consequences.

Objective: To assess the hospital course of patients diagnosed with isolated sternal fracture.

Methods: We reviewed 55 medical records of patients who were admitted with isolated sternal fracture to the emergency department during the period from January 1990 through August 1999.

Results: Fifty-one patients were involved in motor vehicle accidents, and the remainder sustained the injury as a result of a fall. Lateral chest X-ray upon admission was diagnostic in the majority of these patients (n=53). Electrocardiography (n=52) was abnormal in four patients – old myocardial infarction (n=1), non-specific ST-T changes (n=3). Cardiac enzymes (creatine-kinase-MB, n=42) were pathologically elevated in five patients. Echocardiography, performed in patients with ECG[1] abnormalities and/or elevated myocardial enzymes (n=7), was normal in these patients as well as in another 18 patients. There were no intensive care unit admissions or arrhythmias during the hospital stay, which ranged from 6 hours to 6 days (mean 2.3 ± 1.3 days, median 2 days).

Conclusion: Our findings support the view that patients with isolated sternal fracture, who have no abnormality in ECG and cardiac enzymes during the early hours after injury, are expected to have a benign course and can be discharged home from the emergency room within the first 24 hours.

This paper describes "Health Value Added" – an innovative model that links performance measurement to strategy in health maintanance organizations. The HVA[1] model was developed by Maccabi Healthcare Services, Israel’s second largest HMO[2], with the aim of focusing all its activities on providing high quality care within budgetary and regulatory constraints. HVA draws upon theory and practice from strategic management and performance measurement in order to assesses an HMO’s ability to improve the health of its members. The model consists of four interrelated levels – mission, goals, systems, and resources – and builds on the existence of advanced computerized information systems that make comprehensive measurements available to decision makers in real time. HVA enables management to evaluate overall organizational performance as well as the performance of semi-autonomous units. In simple terms, the sophisticated use of performance measures can help healthcare organizations obtain more health for the same money.

Background: Damage to the intervertebral disk is usually corrected by means of a prosthesis.

Objectives: To report the outcome of the artificial lumbar disk replacement with the Charité SB III disk prosthesis in 20 patients after a 48 month follow-up.

Methods: The 20 patients were evaluated clinically and radiographically during this period. Preoperative diagnosis included degenerative diskopathy in 17 patients and failed posterior conventional diskectomy in 3. The prosthesis was implanted at one level in 17 patients and bi-level implantation was performed in the other 3 patients.

Results: Eighty percent of patients reported satisfactory to very good results. Poor results were reported by four patients, one of whom underwent posterolateral fusion and another is waiting for the same operation. There were two dislocations of the prosthesis followed by immediate revision surgery.

Conclusions: Contraindications for surgery appear to be the principal cause of failure rather than the prosthesis itself.
 

Background: With the introduction of surgery and percutaneous balloon valvuloplasty for relieving severe mitral stenosis the natural history of the disease has markedly altered.

Objectives: To determine the natural history of patients with moderate mitral valve stenosis.

Methods: Demographic, clinical and echocardiographic data were evaluated in 36 patients with moderate mitral stenosis during a follow-up of 71 ± 15 months.

Results: The 36 patients comprised 32 women and 4 men with a mean age of 43.7 ± 12.2 years; 28 were Jewish and 8 were of Arab origin. During follow-up, there was a significant decrease in mitral valve area, with an increase in mean mitral valve gradient and score. Mean loss of mitral valve area was 0.04 ± 0.11 cm²/year. No correlation was found between disease progression and age, past mitral valve commissurotomy, baseline mean gradient or mitral valve score. Larger baseline mitral valve area (P = 0.007) and Arab origin (P = 0.03) had an independent correlation to loss of mitral valve area. Fifteen patients (42%) did demonstrate any loss in mitral valve area during the follow-up period.

Conclusions: The rate of mitral valve narrowing in patients with moderate mitral stenosis is variable and cannot be predicted by patient’s age, past commissurotomy, valve score or gradient. Secondly, larger baseline mitral valve area and Arab origin showed an independent correlation to loss of mitral valve area; and finally, in many patients valve area did not change over a long observation period.
 

Background: Menopause affects women's health and well-being, but their knowledge of proper care and maintenance is uncertain.

Objective: To assess the attitude and approach of the healthy, low risk, postmenopausal population in Israel to personal healthcare and menopause.

Methods: The study population comprised 500 menopausal women attending community outpatient primary care clinics. All women completed a 20-item questionnaire covering personal healthcare habits, lifestyle, knowledge about menopause, and attitude and approach to menopause and use of hormone replacement therapy.

Results: The patients' mean body mass index was 25.8 ± 4.1 kg/m²; more than half the women were overweight, 28% percent engaged in regular sports activity, nd 11.2% smoked; 74% had a positive attitude towards their age; 60% underwent yearly screening mammography; 74% have had Pap smear and 86% had lipid profile measurements during the last year; self-examination of the breast was regularly performed by only 49%. HRT[1] is currently being used by 27% and had been used in the past by another 16%. The primary reasons for stopping therapy were irregular bleeding in 38% and apparent ineffectiveness in 35%. There was a positive significant correlation between level of education and both undergoing regular medical screening and engaging in regular sports activity. HRT current utilization was negatively associated with age and being a housewife.

Conclusions: A relatively high percentage of the study population safeguards its health and regularly uses HRT. We believe that stronger efforts are needed in Israel to promote good healthcare habits and positive attitudes toward menopause and HRT use.
