Since the early 1980s demographic changes compelled Israel’s health system to dedicate efforts to establish modern geriatric services. This task was performed with the help of governmental and non-governmental institutions and was coordinated by the Division of Geriatrics and Long-Term Care Diseases of the Ministry of Health. Today, 20 years later, as a result of those efforts, geriatrics and geriatric services in Israel are thriving. Qualified staff, including physicians who specialized in geriatrics, are working to maintain a high quality of care in various geriatric settings. However, more resources should be allocated for research in order to maintain and to continue to develop geriatric medicine in Israel.

Background: The chronic progressive course of peripheral arterial occlusive disease with its limb-threatening and life-threatening potential is associated with physical, psychological and social distress for elderly patients and their families.

Objective: To evaluate the influence of infra-inguinal bypass surgery for limb salvage, and social support, on quality of life in elderly patients (over 60 years old).

Methods: Sixty patients aged 60 years and above diagnosed with limb-threatening ischemia were evaluated using the SF-36 generic questionnaire for quality of life, and the MOS-SS questionnaire for social support. Thirty patients (group I) were evaluated in the hospital prior to reconstructive surgery and 30 postoperative patients (group II) were evaluated at home at least 6 months after infra-inguinal bypass operations. Both groups were comparable in terms of age, gender, prevalence of ischemic heart disease, diabetes, and other atherosclerosis risk factors.

Results: All quality of life parameters were higher among patients who underwent limb salvage surgery (group II) as compared to preoperative patients (group I), yet the obtained values were lower than those in the general population. Patients in the surgical intervention group had higher levels of function, lower pain levels, and higher emotional and social well-being and, in addition, were spared limb amputation. The findings also indicate that the social support dimensions (emotional support, receipt of information, affection and positive social interaction), as measured in terms of perceived availability, do not operate as one entity. Different types of social support were more beneficial along different stages of the disease.

Conclusion: Peripheral arterial occlusive disease causes severe impairment of the quality of life in elderly patients. Arterial reconstructive surgery improves the quality of life though it still remains low compared to the general population. Social support is beneficial in the treatment of these patients, and the social worker in the vascular surgery department has a key role in identifying the various needs of the patients along the path of their chronic illness.
 

Background: An important question on the health agenda concerns the most appropriate place to hospitalize stroke patients and its effect on acute stroke care.

Objectives: To examine how the existing hospital system treats these patients, specifically: a) the departments to which stroke patients are admitted; b) differences in the admission, diagnosis and rehabilitative care of stroke patients, by department; c) patient characteristics, by department; and d) mortality rates during hospitalization.

Methods: We surveyed 616 people with acute stroke (ICD-CM9 430-433, 436) admitted consecutively to one of seven large general hospitals in Israel between October 1998 and January 1999. Data were collected from medical records at admission and at discharge.

Results: Forty-two percent of the patients were admitted to an internal medicine department, 56% to a neurology department, and only 2% to a geriatric department. The majority (95%) underwent a computed tomography scan of the brain, but other imaging tests were performed on fewer patients, with significant differences among hospitals and between internal medicine and neurology departments. Patients admitted to neurology departments were younger and had milder stroke symptoms than did patients admitted to internal medicine departments. Fifty-three percent of patients received at least one type of rehabilitative care during their hospital stay – usually physiotherapy, and least often occupational therapy. Seventeen percent of stroke patients died during hospitalization. Mortality was not found to be related to the admitting department.

Conclusions: Uniform realistic policies and work procedures should be formulated for all hospitals in Israel regarding the admitting department and processes as well as the performance of diagnostic imaging. Standards of medical and rehabilitative care and discharge destination should be developed to promote quality of care while containing utilization and costs.
 

Matrix metalloproteinases are a family of enzymes that degrade different components of extracellular matrix. They play an important role in normal physiologic processes of maintaining tissue integrity and remodeling, as in wound healing, processes of development, and regeneration. However, excessive expression of MMP[1] has been observed in many disease states, including rheumatoid arthritis and osteoarthritis, vascular remodeling in atherosclerosis and aortic aneurysm formation, neoplastic processes, macular degeneration and many others.

Background: Multifetal pregnancy reduction has been implemented for improving the outcome of multifetal pregnancies. Recent studies reported no difference in pregnancy outcome between reduced twins and non-reduced twins, but the neonatal course and subsequent outcome in reduced twin pregnancies were not well documented.

Objective: To compare the neonatal course and outcome, as well as the gestational and labor characteristics, in twins from reduced multifetal pregnancies and in non-reduced twins.

Methods: This is a retrospective case-control study of the neonatal course of twins from reduced multifetal pregnancies. We found 64 mothers with multifetal pregnancy reduction who delivered twins during 1989–1997; 64 gestational age-matched non-reduced twin pregnancies served as controls. The following neonatal variables were examined: major malformations; small birth weight for gestational age; and neonatal morbidities including respiratory distress syndrome, apnea, pneumothorax, bronchopulmonary dysplasia, hyperbilirubinemia, sepsis, necrotizing enterocolitis, retinopathy of prematurity, seizures, intraventricular hemorrhage, periventricular leukomalacia, ventriculomegaly, and hydrocephalus. In addition, we evaluated several neonatal interventions (surfactant replacement, mechanical ventilation, phototherapy, total parenteral nutrition), and some laboratory abnormalities (thrombocytopenia, leukopenia, anemia, and hypoglycemia), duration of hospitalization, and neonatal mortality.

Results: Gestational and labor variables were not significantly different between multifetal pregnancies reduced to twins and non-reduced twin pregnancies. The neonatal morbidity and mortality were not significantly different between twin neonates from multifetal pregnancy reduction and non-reduced control twins.

Conclusions: Multifetal pregnancy reduction to twins appears to bear no adverse effect on the intrauterine course of the remaining fetuses or their neonatal course and outcome when born after 28 weeks of gestation.
 

Background: Although the preferred management of a patient presenting with an acute myocardial infarction is in a coronary care unit, data based on discharge diagnoses in Israel indicate that many of these patients are treated outside such units.

Objectives: To compare the demographic and clinical characteristics, treatment and mortality of AMI[1] patients treated inside and outside a CCU[2].

Methods: We compiled a registry of all patients admitted to three general hospitals in Haifa, Israel during January, March, May, July, September and November 1996.

Results: The non-CCU admission rate was 22%. CCU patients were younger (61.6 vs. 65.5 years), less likely to report a past AMI (18% vs. 34%), and arrived earlier at the emergency room. Non-CCU patients were more likely to present with severe heart failure (30 vs. 11%). Non-CCU patients received less aspirin (81 vs. 95%) and beta-blockers (62 vs. 80%). Upon discharge, these patients were less frequently prescribed beta-blockers and cardiac rehabilitation programs. CCU-treated patients had lower unadjusted mortality rates at both 30 days (odds ratio=0.35) and in the long term (hazards ratio=0.57). These ratios were attenuated after controlling for gender, age, type of AMI, and degree of heart failure (OR[3]=0.91 and HR[4]=0.78, respectively).

Conclusions: A relatively high proportion of AMI patients were treated outside a CCU, with older and sicker patients being denied admission to a CCU. The process of evidence-based care by cardiologists was preferable to that of internists both during the hospital stay and at discharge. In Israel a significant proportion of all AMI admissions are initially treated outside a CCU. Emphasis on increasing awareness in internal medicine departments to evidence-based care of AMI is indicated.

Background: The incidence of malignant musculoskeletal tumors during pregnancy is very low. The paucity of data precludes the drawing of solid conclusions regarding a standard approach.

Objectives: To summarize our experience treating 13 pregnant women with malignant soft tissue or bone tumors.

Methods: We conducted a retrospective analysis of 13 cases of patients with either soft tissue or bone sarcoma that developed or progressed during pregnancy or immediately after delivery.

Results: The clinical presentation of the tumors was either a growing mass and/or increasing pain and disability. Most of the masses were located in the lower part of the body and of considerable size. Treatment given during gestation was limited to wide excision of the mass in the 28th week of gestation in one patient. All the patients reported disease progression during gestation. Vaginal delivery was possible in eight patients with no complications, cesarean section was carried out in three women, spontaneous miscarriage occurred in one and termination of pregnancy was performed in one patient.

Conclusions: The diagnostic and therapeutic approaches should be tailored specifically in every pregnant woman in whom sarcoma is suspected.
 

Background: Puncture wounds in the feet of children present a clinical dilemma.

Objectives: To evaluate our approach, we reviewed the charts and all available images of 80 children admitted to our institution because of plantar punctures from 1988 to 1999.

Methods: The charts of 80 children were reviewed retrospectively.

Results: Three groups of patients were found: 59 with superficial cellulitis, 11 with retained foreign bodies, and 10 with osteomyelitis and/or septic arthritis. There was a significant presentation delay in patients from the second and third groups. Most common organisms were Staphylococcus aureus or Group A Streptococcus. Of the 80 children, 34 were treated surgically and 46 were treated with antibiotic therapy alone. All patients with osteomyelitis and septic arthritis were re-examined; at follow-up, all but one were asymptomatic apart from residual radiologic sequelae in four.

Conclusions: Patients with an established infection 24–36 hours after a plantar puncture should be admitted to hospital for parenteral antibiotic therapy. Delayed presentation is a significant marker for deep-seated infection. Further infection or relapse after initial improvement suggests the presence of osteomyelitis or a retained foreign body. A bone scan is advisable in all patients with suspected osteomyelitis: a positive bone scan necessitates aggressive early debridement combined with appropriate antibiotics; while negative bone scan, X-ray and exploration suggest that the infection is due to a foreign body, which can be detected by computed tomography.
 

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.

Background: Coronary stenting was recently introduced as a primary intervention for acute myocardial infarction. Several randomized controlled studies have shown that stenting may be superior to balloon angioplasty for the treatment of AMI[1]. However, routine stenting may also cause deterioration of coronary flow.

Objective: To analyze the clinical characteristics and the outcome of patients who were treated with stenting for AMI in our center in the recent era of stenting.

Methods: Fifty-five patients with AMI were treated by stent implantation between January 1998 and December 1999. Adverse clinical events were recorded, including death, recurrent infarction, coronary artery bypass grafting, cerebrovascular accident, and target vessel revascularization. In-hospital, 1 month, 6 month and 1 year follow-up was performed in all patients. Repeated coronary angiography was performed according to clinical indications.

Results: Baseline angiographic results showed Thrombolysis in Myocardial Infarction (TIMI) 0 flow in 39 patients (70.9%), TIMI I flow in no patient and TIMI II/III flow in 16 patients (29.1%). TIMI grade 3 flow was achieved in 90.9% of patients at the end of the procedure. In-hospital mortality rate was 5.4% (2.1% in patients without cardiogenic shock). There was no evidence of re-infarction or TVR[2]. The rates of bleeding complication (all of them minor), CVA[3], and CABG[4] were 9.1%, 3.6% and 1.8% respectively. The 6 month mortality rate remained the same. Rates of re-infarction, restenosis, TVR and CABG were 3.6%, 14.5%, 14.5% and 5.4% respectively. The 1 year mortality rate was 7.3%. Restenosis rate was 18% and CABG 7.3%. One year event-free survival was 70.9%.

Conclusions: This study suggests that stenting is a safe and effective mode of therapy in the setting of AMI associated with a high rate of revascularization and a low short and long-term outcome.
