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: While age at death is on the rise, the number of postmortem examinations is declining and is disproportionately low among the elderly population. Research on the subject of gender-associated pathology in the elderly is also scarce.

Objective: To seek eventual gender-related differences in autopsies of elderly patients.

Methods: We analyzed the data extracted from a published report on 93 PMEs[1] performed at a geriatric hospital during the past 20 years.

Results: Ninety-three autopsies, representing 1.2% of the 8,101 deaths during these 20 years, were performed. Forty-five of the deceased were women and 48 were men. The incidence of pulmonary embolism was significantly higher in women (28%) than in men (10%) (P< 0.02). There was no significant difference in the gender distribution of the other diagnoses.

Conclusion: Gender distribution of PME-based causes of death in elderly patients revealed a significant rate of pulmonary embolism in women. A thorough search of the medical literature revealed two previous studies with similar findings. Further research will determine whether pulmonary embolism is more frequent or whether it has a worse prognosis in frail elderly women.

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.

In 2001 the number of residents aged 65 and over in Israel was 639,000, or 10% of the population. The rate of increase of the elderly population is twice that of the general population, thus the predicted number of elderly for 2020 is around 1,025,000, representing a 60% increase. While this process is determined by a decline in both fertility and mortality, in Israel, immigration has also been a central factor in the process of aging. Life expectancy stands at 76.7 for men and 80.9 for women; at age 65 it is 16.4 years for men and 18.5 for women. The major factor influencing the increase in life expectancy during the past two decades has been the prevention of death among older people. Population aging, or “the demographic transition,” also represents an "epidemiological transition” – from high rates of infectious and communicable diseases, to high rates of chronic diseases among older people. During the past two decades, the number of disabled elderly has increased more than 2.5 times. In 2001, there were about 97,400 disabled elderly in Israel, constituting about 15% of all elderly. By the year 2010, the number of disabled elderly is expected to reach 120,100. The rate of increase of the disabled elderly population is almost double that of the total elderly population, due to changes in this population’s composition. However, recent research indicates that new cohorts of elderly are healthier than earlier cohorts but experience a decline in health at older ages. While advances in standard of living, medicine, and technology have made this possible, a greater allocation of resources is required to prevent disability and maintain the quality of life.

Background: Little information is available on the clinical practice and implementation of guidelines in treating acute myocardial infarction patients in Israel.

Objective: To assess patient characteristics, hospital course, management, and 30 day clinical outcome of all AMI[1] patients hospitalized in Israel during a 2 month period in 2000.

Method: We conducted a prospective 2 month survey of consecutive AMI patients admitted to 82 of 96 internal medicine departments and all 26 cardiac departments operating in Israel in 2000. Data were collected uniformly by means of a hospital and 30 day follow-up form.

Results: During the survey 1,683 consecutive patients with a discharge diagnosis of AMI were included. Their mean age was 66 years; 73% were male. The electrocardiographic pattern on admission revealed ST elevation, non-ST elevation and an undetermined ECG[2] in 63%, 34% and 4% of patients respectively. Aspirin and heparin were given to 95% of patients. Beta-blockers and angiotensin-converting enzyme inhibitors were given to 76% and 65% of patients respectively. Among hospital survivors, 45% received lipid-lowering drugs. Thrombolytic therapy was administered in 28% of patients, coronary angiography was used in 45%, and 7% of patients underwent primary percutaneous coronary intervention. The 7 and 30 day mortality rates were 7% and 11% respectively.

Conclusions: This nationwide survey shows that one-third of the AMI patients in Israel are elderly (≥ 75 years). The survey suggests that clinical guidelines for the management of patients with AMI are partially implemented in the community. Data from large surveys representing the "real world" practice are of utmost importance for the evaluation of clinical guidelines, research and educational purposes.

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 frequent systemic side effects associated with the use of systemic carbonic anhydrase inhibitors have adversely affected the compliance to treatment in glaucoma patients, obviating their long-term use. The introduction of the topical CAI[1], dorzolamide, has further reduced their use. However, the tolerability of dorzolamide in patients who have been intolerant to systemic CAIs has not been evaluated prospectively.

Objectives: To study the tolerability and efficacy of dorzolamide (a topical CAI) in a selected group of glaucoma and ocular hypertensive patients who have been intolerant to systemic CAI.

Methods: A 3 month prospective study was conducted in 39 patients. Following recruitment, patients were evaluated on the day of switching from systemic CAI to dorzolamide and for five more visits. The SF-36 health assessment questionnaire was used to evaluate changes in well-being and quality of life, and the intraocular pressure was measured periodically.

Results: Within 4 weeks of switching from systemic CAI to dorzolamide, the mean health assessment scores improved significantly in seven of the eight categories of the SF-36, and remained generally unchanged for the rest of the study. No significant differences were noted between the mean IOP[2] on day 0 and the following measurements throughout the 84 days of dorzolamide therapy.

Conclusion: In glaucoma patients who were intolerant to systemic CAI, topical CAI dorzolamide offers a similar efficacy and better tolerability.

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.
 

Vasopressin is a potent endogenous vasoconstrictor that increases blood pressure and systemic vascular resistance. The administration of exogenous vasopressin during closed and open cardiopulmonary resuscitation in humans was shown to be more effective than optimal doses of epinephrine in several clinical studies. We summarize here the recent experimental and clinical data on the use of vasopressin in cardiopulmonary resuscitation and septic shock. As the use of vasopressin in human resuscitation is now in its early stages, it is expected that accumulated future experience will shed more light regarding the risk-benefit aspects of its use.

Micronutrient deficiencies have reoccupied the center stage of public health policy with the realization that folic acid deficiency results in neural tube defects and possibly other birth defects as well as ischemic heart disease. These, in turn, have raised an older debate on food fortification policy for the elimination of iodine, iron and vitamin D deficiencies. Data from the First Israeli National Health and Nutrition Survey (MABAT 2000) provided an impetus to develop an active national nutrition policy aimed to improve the nutritional status of iodine, iron, vitamins A and D and B-vitamins, including folate. In this paper we examine some of the MND[1] issues in Israel and their implications for public health, and suggest options for the formulation of policy.
