Background: Cystinuria is an autosomal recessive disease that is manifested by the development of kidney stones. Mutations in SLC3A1 cause type I disease, while mutations in SLC7A9 are associated with non-type I disease. In Israel cystinuria is especially common among Libyan Jews who suffer from non-type I disease.

Objectives: To compare clinical manifestations of patients with mutations in SLC3A1 to those with mutations in SLC7A9, and to assess the carrier rate among unaffected Libyan Jewish controls.

Methods: Clinical manifestations were evaluated in patients with mutations in SLC3A1 and in patients with mutations in SLC7A9. Carrier rates for two SLC7A9 mutations were assessed in 287 unaffected Libyan Jewish controls.

Results: Twelve patients with mutations in SLC3A1 were compared to 15 patients with mutations in SLC7A9. No differences were detected between the patients with mutations in SLC3A1 and those with mutations in SLC7A9 in relation to the age of disease onset, the estimated number of stones, the number of invasive procedures, the number of patients receiving drug therapy, or the patients’ urinary pH. Eleven of the unaffected Libyan Jewish controls were found heterozygotes for the V170M mutation, establishing a carrier rate of 1:25. The 1584+3 del AAGT mutation was not found in any of the Libyan Jewish controls.

Conclusion: Mutations in SLC3A1 and SLC7A9 cystinuria patients result in indistinguishable disease manifestations. The high carrier rate among Libyan Jews is a result of a single missense mutation, V170M.
 

The ethical chapter of the Israel Medical Association has recently issued guidelines with regard to exual relationships between doctors and patients or past patients. This paper juxtaposes the paternalistic and severe attitude to doctor-patient sex with the relaxation and individualization of decisions regarding doctors' involvement in assisted suicide, passive and active euthanasia. The discussion bears on our concepts of palliative care and our expectations from it.

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: 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: Risk factors for injurious falls among elderly people differ from those for falls in general. The characteristics of falls play an important role in determining the risk of hip fracture.

Objective: To investigate the risk factors associated with the fall characteristics known to be associated with the majority of hip fractures, e.g., a lateral fall and a subsequent impact on the greater trochanter.

Methods: In this 6 month prospective observational case-control study 101 individuals aged 65 years and over hospitalized following a hip fracture were interviewed 7–14 days after the accident. Data were also obtained from medical records, focusing on known predisposing and situational risk factors for the fall. We compared the risk factors between two groups: patients who suffered a lateral fall and subsequent impact on the greater trochanter of the femur, and patients who suffered other types of falls.

Results: Only 51.5% of the hip fracture patients reported that they had fallen directly to the side. Apart from age, there were no significant differences between the groups in other factors studied. When considering both fall direction and the area that took the main impact, we found that the majority of patients (85%) reported having fallen onto the posterolateral aspect and/or a fall with an impact on the greater trochanter.

Conclusion: Our findings did not show differences (except for age) in the factors studied between the groups. This study suggests that both fall direction and the area that takes the main impact should be considered in the characteristics of falls that might cause a hip fracture. Characteristics associated with greatest fracture risk include a fall onto the posterolateral aspect and/or a fall with an impact on the greater trochanter. More studies are needed to evaluate potential risk factors associated with this type of injury.

Background: Due to multiple chronic illness and disability, the elderly consume a disproportionately large share of medications.

Objectives: To assess the patterns and determinants of drug use among the community dwelling old-old population.

Methods: The study population included 1,369 old-old persons from the baseline data of the Cross-Sectional and Longitudinal Aging Study (CALAS), which is based on a national random stratified sample of the Israeli Jewish population aged 75–94 years.

Results: The mean number of drugs used by the study population was 3.3, and only 12.5% did not consume any drugs. Multivariate linear regression analysis showed that women used significantly more drugs than men, and that those born in Europe took significantly more drugs than those born in Israel and Asia-Africa. The number of medical conditions was the strongest predictor of drug use. Hospitalizations during the last year and frequent visits to family physician were also significant factors related to drug use. All variables combined explained 40% of the variance in drug use by the old-old. The most commonly used therapeutic groups were cardiovascular drugs (53%), psychotropic drugs (31%), analgesics (30%), and gastrointestinal drugs (28%).

Conclusions: Our data indicate that in addition to the association of drug use with health status and healthcare utilization, the number and type of drugs taken vary with gender and place of birth.

Background: With the aging of the population and the increase in the number of elderly patients under the care of primary care physicians in the community, it is essential that the physician be aware of the preventive medicine recommendations for this group of patients. Accepted evidence-based guidelines have been developed for the older patient and adherence to these guidelines may play a significant role in decreasing morbidity and mortality in the elderly.

Objectives: To determine whether elderly patients in community clinics are aware of the preventive medicine practices that are relevant and available to them, and to assess which factors influence their decision to use such interventions. Of particular interest was to evaluate the role of the doctor-patient relationship on the degree of patient compliance with preventive procedures.

Methods: Patients attending community clinics of the Clalit Health Services in Jerusalem were interviewed. Background information was obtained and the patients were questioned regarding the use of the following preventive medicine recommendations: screening for occult blood in the stool, testing of vision and hearing, influenza and pneumococcal immunization, thyroid-stimulating hormone testing, digital rectal examination for prostate cancer, and calcium supplementation. The patients were questioned regarding the use of aspirin or oral anticoagulation where relevant. Factors influencing their level of compliance were examined.

Results: The study group comprised 205 patients with an average age of 74.5 years. Overall the rates of compliance were high, with 78% undergoing visual assessment, 87% fecal occult blood testing, and 81% influenza immunization. Pneumococcal immunization had been administered to 49% of those interviewed and 56% had their hearing tested. Digital rectal examination had been performed in 45% of patients. Calcium supplementation was used in 60% of patients. Almost all the patients (91–100%) noted that the physician had initiated the procedure and that non-compliance was due to patient preferences. Of the 172 patients who were assumed to benefit from aspirin use, 153 (89%) used the medication, and 87% of 23 patients with atrial fibrillation were on chronic anticoagulation.

Conclusions: A high level of compliance with preventive medicine recommendations was found among this group of elderly patients. The doctor-patient relationship had a positive effect on the patients' compliance.
 

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.

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.
