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: Primary hyperparathyroidism in elderly patients is usually associated with additional co-morbidity that increases operative risk, and thus many geriatric patients are denied the benefit of surgery for a single parathyroid adenoma.

Objectives:  To evaluate the safety and efficacy of accurate single photon emission computed tomography sestamibi scintigraphy, enabling precise localization of a single adenoma, in the geriatric population

Methods: Twenty-two patients aged 70 years and over with biochemically proven PHPT[1] and with a single parathyroid adenoma identified by localization studies (sestamibi SPECT[2] scan and ultrasonography) underwent 23 operations over 29 months (out of a total of 140 patients operated upon during the same period). Immediate preoperative sestamibi scintigraphy and marking of focal adenoma uptake followed by intraoperative hand-held gamma probe were used for the removal of the parathyroid adenoma by unilateral minimal access surgery. Associated major co-morbid conditions and pre- and postoperative calcium, phosphorus and parathormone levels were recorded. Indications for surgery were listed and operative and postoperative complications were noted. The patients were followed for a mean period of 17.7 months using the same parameters.

Results: The 22 patients with PHPT had a mean age of 76.3 ± 5.9 years (range 70–88 years)  and a female to male ratio of 13:9. Associated co-morbidity included ischemic heart disease (n=15), hypertension (n=22), non-insulin-dependent diabetes mellitus (n=9), chronic obstructive pulmonary disease (n=3), and previous neck surgery (n=3). Mean preoperative serum calcium, phosphorous and PTH[3] were 11.7 ± 1.3 mg/dl, 2.5 ± 0.5 mg/dl and 160.9 ± 75.4 pg/ml respectively. In 20 of the 22 patients, surgery was successful in curing PHPT (91%). One patient had persistent hypercalcemia due to a missed adenoma, and repeat operation (by focused minimal access surgery) was successfully performed 2 weeks later. There were no complications and no morbidity postoperatively. Mean postoperative serum calcium, phosphorous and PTH were 9.6 ± 1.2 mg/dl, 3.0 ± 0.5 mg/dl and 35.2 ± 24 pg/ml respectively. In all patients, serum calcium levels remained normal (9.7 ± 1.3 mg/ml) after long-term follow-up (mean 17.7 ± 9.6 months).

Conclusions: Minimally invasive, radio-guided focused parathyroidectomy for a single adenoma is a safe and effective method to cure hyperparathyroidism in the elderly. Success of surgery is directly related to the surgeon's experience and to the precise localization marking provided by sestamibi scintigraphic SPECT localization and concurrent sonographic findings.

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.

The Arab population of Israel is relatively young. However, a significant increase is expected in the number of elderly Arabs in the coming years. At the end of 2001 there were 38,500 Arab elderly, but their number is expected to reach 92,100 by 2020. This will represent a nearly 2.5-fold increase in absolute numbers. As the population ages, the number and percentage of people with chronic diseases and related disabilities will rise significantly. While the Arab elderly are much younger than the Jewish elderly, they are more disabled and therefore have greater medical and nursing needs. An extremely important measure of the need for formal services is an elderly person’s functional ability, especially the ability to live independently. The percentage of Arab elderly who are disabled and need help with activities of daily living is two times higher than that of the Jewish elderly population. At present, 30% of the Arab elderly (39% of the women and 20% of the men), compared to 14% of Jewish elderly (17% of the women and 11% of the men), need help in at least one ADL[1] (bathing, dressing, eating, mobility in the home, rising and sitting, getting in and out of bed). Concomitant with demographic changes are forces that affect the ability of informal support systems to provide care. For example, the rising number of Arab women in the labor force together with changes in elderly peoples' living arrangements have increased the need for formal services to share responsibility for the elderly with families. As services are developed, questions arise regarding the extent to which they have been adapted to the culture and norms of Arab society and meet that society’s unique needs. This paper elaborates on some of these issues.

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.

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.

Background: The mainstay of therapy for acute cholecystitis is cholecystectomy, which has a mortality of 14–30% in high risk patients. An alternative approach in patients suffering from acute cholecystitis with contraindications to emergency surgery is percutaneous cholecystostomy.

Objective: To evaluate the efficacy and safety of percutaneous cholecystostomy as the initial treatment of acute cholecystitis in high risk patients.

Methods: Eighty consecutive patients (42 men, 38 women) underwent ultrasound-guided percutaneous cholecystostomy over a 5 year period. Sixty-five patients suffered from acute calculous cholecystitis, 4 patients had acalculous cholecystitis, and 11 patients had sepsis of unknown origin.

Results: Sixty-eight patients improved after the percutaneous gallbladder drainage, 10 patients died from co-morbid disease and 2 patients died from biliary peritonitis. During a 1 year follow-up, 32 of the patients underwent interval cholecystectomy, 4 additional patients died from a co-morbid disease, 18 patients did not suffer from any gallbladder symptoms, and 14 were lost to follow-up.

Conclusions: Percutaneous cholecystostomy is an effective contribution to the treatment of acute cholecystitis in high risk patients.
