Objective and Importance:Cerebral vasculitis (CV) is a rare described complication of rheumatoid arthritis (RA). Although the most frequent neurological manifestations RA are peripheral neuropathy cervical spinal cord compression due to subluxation vertebrae, CV can be seen especially in patients with seropositive long-standing RA.Clinical presentation: We report two cases associated RA. Both had no extraarticular clinics were under control. Our first case 30-years-old woman for 15 years who...

Insulin resistance has effects on the coagulation system, which is important in acute phase of infarct. We examined relationships between insulin resistance, hemostatic markers and stroke severity ischemic patients.Protein C (PC), protein S (PS), fibrinogen, von Willebrand factor antithrombin III (AT III) were studied 75 patients with without resistance.The PC PS levels insulin-resistant significantly lower than those non-insulin-resistant (PC: 87 ± 19.23 vs. 97.89 13.3%, p = 0.007; PS:...

The aim of this study was to elucidate the possible association between carpal tunnel syndrome (CTS) and ulnar neuropathy at wrist because contradictory results previous studies. Thus, a retrospective case-control arranged with an electromyographic database including patients 2003 2009. Patients were selected according initial diagnosis examiner's criteria, data plotted by computer. One thousand nine hundred twenty-four evaluated for CTS 1,024 diabetic or polyneuropathy. co-occurrence alone...

Our aims were to observe the effects of rehabilitation and surgery on idiopathic diabetic carpal tunnel syndrome (CTS) compare them with natural course disease. Forty-two patients aged 33 74 years clinically diagnosed, electrophysiologically confirmed, laboratory screened hands CTS (46 34 diabetic) enrolled in study. Improvement symptom severity functional status after treatment using Boston questionnaire (scales), changes nerve conduction parameters (NCPs), correlations between NCP...

Objective The transfemoral approach is a common route for catheterization of the supra-aortic vessels in neuroendovascular therapy. However, some cases, patient's anatomy prevents or distal access to carotid s. In such direct exposure (DCE) approaches may be used treat cerebrovascular diseases. Methods We present 11 cases which we were unable perform and DCE was preferred treatment procedure. Results performed on patients with cerebral aneurysm (n = 8), cavernous fistula (CCF) 1), malignant...

INTRODUCTION: Anatomic variations of cerebral arteries may influence the development aneurysms.In this study our aim was to determine vascular anatomical anterior circulation brain in patients with and without aneurysms also relationship between variations.METHODS: The digital subtraction angiography data 438 were investigated retrospectively.Anatomical MCA ACA-AcomA complex separately aneurysm.RESULTS: Most had SAH (n: 68, 80%).Although normal ACA AcomA anatomy less frequently seen SAH,...

The regression of meningioma has been reported in literature before. In spite the fact that may be involved by hemorrhage, calcification or some drugs withdrawal, it is rarely observed spontaneously.We report a 17 year old man with cervical which was incidentally detected. his MRI an extradural, cranio-caudal contrast enchanced lesion at C2-C3 levels spinal cord Despite slight compression towards cord, he had no symptoms and refused any kind surgical approach. followed control spontaneously...

The role of inflammation in the pathogenesis acute ischemic stroke is well known, but its association with clinical picture as yet unclear.In our study, we measured serum levels proinflammatory cytokines interleukin-1beta (IL-1beta), tumor necrosis factor alpha (TNFalpha) and interleukin-6 (IL-6) within first 50 h 60 patients, examined natural anticoagulants protein C free S. We compared results a control group that consisted 30 volunteers. also correlated their outcomes by using Canadian...

BACKGROUND: The recurrent Heubner's artery is the distal part of medial striate artery. Occlusion Heubner, classically contralateral hemiparesis with fasciobrachiocrural predominance, attributed to occlusion Heubner and widely known as a stroke syndrome in adults. However, isolated deep perforating arteries following mild head trauma also occurs extremely rarely childhood.CASE REPORT: Here we report case an 11-year-old boy pure motor stroke. brain MRI showed acute ischemia supply area...

Objective The transradial catheterization (TRC) is becoming widespread, primarily for neurointerventions. Therefore, the evaluation of radial artery puncture in clinical practice and a better understanding anatomy are important to improve safety neuroendovascular surgery. Methods Ten formalin-fixed adult Korean cadavers were dissected expose (RA), brachial (BrA) subclvian (ScA), bilaterally. Vessel lengths diameters meaured using caliper distance between specific point vessels anatomical...

We evaluated the predictive factors of symptomatic intracranial hemorrhage (SICH) in endovascular treatment stroke. included 975 ischemic stroke patients with anterior circulation occlusion. Patients that had and an increase ≥4 points their National Institutes Health Stroke Scale (NIHSS) after were considered as SICH. The mean age was 65.2±13.1 years 469 (48.1%) women. median NIHSS 16 (13-18) Alberta Program Early CT 9 (8-10). In 420 (43.1%), modified Rankin favorable (0-2) mortality...

In this article, 2 patients with chronic inflammatory demyelinating polyneuropathy (CIDP) are presented. These developed respiratory failure which could not be explained by any cardiac or pulmonary pathology. The first case had pure motor involvement and probable CIDP, the second severe sensorial dysfunction an ataxic picture in addition to symptoms. His clinical was compatible distal acquired sensory neuropathy without M protein. Electrophysiologic investigations of both disclosed impaired...
