[Guidelines for the management of acute stroke--2005].

Stroke is a major cause for morbidity and mortality in Israel, the third most common cause of death and the main cause for neurological disability among adults. Several significant breakthroughs occurred over recent years in the management of stroke, and acute stroke has increasingly been recognized as a medical emergency--a "brain attack" comparable to a "heart attack". Several new scientific publications, guidelines and consensus statements from Europe and North America necessitate a paradigm shift in the management of acute stroke. The guidelines focus on a number of issues: acute stroke as a medical emergency, dedicated stroke units, early reperfusion therapy for acute ischemic stroke, emergency management and general stroke treatment, use of diagnostic tests in the acute phase, and the prevention and treatment of complications.

Thromboembolic prophylaxis in nonrheumatic atrial fibrillation: utilization patterns, efficacy, and complications in a long-term follow-up of community patients.

OBJECTIVES: To define the incidence, contemporary utilization patterns, efficacy, and complications of thromboembolic prophylactic treatment in patients with chronic (CAF) and paroxysmal atrial fibrillation (PAF). BACKGROUND: Although recent randomized trials with antithrombotic therapy in nonrheumatic atrial fibrillation (AF) patients emphasized the benefits of warfarin in preventing stroke, warfarin treatment is still far from optimal. METHODS: A retrospective analysis of the medical records of 506 patients with nonrheumatic PAF or CAF from 23 clinics in the north of Israel, including an interview with the patients' family physician. RESULTS: (1) The most effective treatment for preventing thromboembolic events (a reduction of 75.9%) was warfarin at an international normalized ratio (INR) intensity of 2-3. (2) After diagnosis, 26.9% of the patients were treated with warfarin. (3) During the follow-up period (not following a thromboembolic event), an additional 26.9% of the patients began treatment with warfarin. (4) Elderly patients (p<0.001), patients with limited activity of daily living (ADL) (p<0.012) or instrumental activity of daily living (IADL) (p<0.001), and patients with PAF (p<0.0001) were less likely to be treated with warfarin. (5) Three new risk factors found for thromboembolic event were limited ADL (p<0.001), limited IADL (p<0.002), and extended duration of AF (p<0.006). CONCLUSIONS: Less than optimal utilization patterns of thromboembolic prophylactic treatment with anticoagulants were found, especially regarding elderly patients, patients with limited ADL and IADL, and patients with PAF, despite the fact that their thromboembolic risk is as high or higher than that of other patients with AF.

Effect of erythropoietin therapy on polyneuropathy in predialytic patients.

BACKGROUND: Peripheral neuropathy commonly develops in patients with advanced chronic renal failure. The uremic neuropathy is often subclinical and detectable only by electrophysiological studies. Receptors to erythropoietin (EPO) have been described on non-hematopoietic cells including neuronal cells. METHODS: In order to evaluate the effect of five months' EPO therapy on polyneuropathy in predialytic patients, nerve conduction studies (NCS) were done in 46 anemic predialytic patients without neurological complaints. In 22 (twelve non-diabetic and ten diabetic) neuropathy was detected and these patients were included in the study. After five months of subcutaneous EPO therapy NCSs were repeated. RESULTS: Hemoglobin increased significantly (p=0.0001) with no significant increase in plasma creatinine. Motor nerve conduction velocity (MNCV) and compound muscle action potentials (CMAP) of the ulnar nerve were normal before EPO therapy and at the end of the study. MNCV of the median, peroneal and tibial nerves improved significantly (p<0.05). CMAP of the median nerve rose significantly, to the normal range (p=0.01). Sensory nerve conduction velocity (SNCV ) and sensory nerve action potentials (SNAP) were reduced in all sensory nerves and did not improve. The improvement in non-diabetic patients was better than in diabetic patients. No significant correlation was found between the increase in hemoglobin and the improvement in MNCV. CONCLUSIONS: Subcutaneous EPO therapy improved motor polyneuropathy in uremic patients, especially non-diabetic individuals. The improvement in MNCV may reflect remyelination. This non-hematopoietic effect may be related to some direct action through EPO receptors on peripheral neuronal cells.
