Only one case of a cow infected with bovine spongiform encephalopathy has been reported in Israel. Its publication, in 2002, caused both public and professional concern. The inevitable health policy question raised was whether or not to recommend against consuming beef and what public health measures should be taken. In this article we describe the prion diseases among animals and humans, their interaction and the precautionary procedures that were carried out by the state Veterinary Services and the Ministry of Health since 1988. The BSE[1] case (a 10 year old dairy cow) is believed to be the result of local consumption of infected food with mammalian meat and bone meal more than a decade earlier. The risk assessment took into consideration that no cases of vCJD (a new variant of Creutzfeldt-Jacob disease) have ever been diagnosed in Israel, as well as the low risk of contamination of the meat due to the religious method of slaughtering performed in the country. The policy decision was to implement a contingency plan prepared in advance. Israel was reclassified from the level II category of geographic risk where BSE is unlikely but not excluded in the herds, to level III, where BSE is likely but not confirmed, or confirmed at a lower level. No undue damage to the meat industry has occurred. By the end of 2002, despite the examination of more than 3,800 brains from slaughtered cows older than 3 years, no other cases of BSE have been detected.

Background: Lower limb critical ischemia is a major problem in dialysed patients.

Objective: To evaluate the results of revascularization procedures, amputations and prosthetic rehabilitation in dialysed amputees.

Methods: Major amputation was carried out in 48 patients (4.5% of the dialysis population), and 24 patients entered the rehabilitation program. Widespread arterial calcification was common and led to falsely elevated ankle-brachial pressure indices in 9 of 14 limbs. Eight patients underwent revascularization. Subsequent major amputation was carried out 4 ± 4.5 months after the revascularization (above knee in 5 patients and below knee in 3). Of the 16 patients who underwent primary amputation, only 2 were above-knee amputees. Seven patients with toe or metatarsal amputation went on to a major amputation 1.8 ± 1.2 months after the distal amputation.

Results: No differences were found between diabetic and non-diabetic patients regarding the number of revascularization operations performed, the level of major amputation, or overall survival. Prosthetic rehabilitation was considered successful in 12 patients, partially successful in 8, and failed in 4 patients. Patient survival time was shortest in those patients with failed rehabilitation. A younger age confirmed favorable rehabilitation results, while long-standing diabetics and bilateral amputees were poor rehabilitation candidates. Patients who underwent primary amputation had more successful rehabilitation. A comparison between 24 dialysed amputees and 138 non-uremic amputees revealed similar rehabilitation results, although hospitalization time was longer in the dialysed patients.

Conclusions: Early definitive therapy is essential when dealing with critical ischemia. After diagnostic angiography, proximal revascularization should be performed where feasible. Primary amputation is indicated in patients with extensive foot infection or gangrene. Prosthetic rehabilitation is warranted in most dialysed amputees.
