Objective: To determine the accuracy of median nerve T2 evaluation and its relation with Boston Questionnaire (BQ) and nerve conduction studies (NCSs) in pre-operative and post-operative carpal tunnel syndrome (CTS) patients in comparison with healthy volunteers., Methods: Twenty-three CTS patients and 24 healthy volunteers underwent NCSs, median nerve T2 evaluation and self-administered BQ. Pre-operative and 1st year post-operative median nerve T2 values and cross-sectional areas (CSAs) were compared both within pre-operative and post-operative CTS groups, and with healthy volunteers. The relationship between MRI findings and BQ and NCSs was analyzed. The ROC curve analysis was used for determining the accuracy., Results: The comparison of pre-operative and post-operative T2 values and CSAs revealed statistically significant improvements in the post-operative patient group (p<0.001 for all parameters). There were positive correlations between T2 values at all levels and BQ values, and positive and negative correlations were also found regarding T2 values and NCS findings in CTS patients. The receiver operating characteristic curve analysis for defined cut-off levels of median nerve T2 values in hands with severe CTS yielded excellent accuracy at all levels. However, this accuracy could not be demonstrated in hands with mild CTS., Conclusion: This study is the first to analyze T2 values in both pre-operative and post-operative CTS patients. The presence of increased T2 values in CTS patients compared to controls and excellent accuracy in hands with severe CTS indicates T2 signal changes related to CTS pathophysiology and possible utilization of T2 signal evaluation in hands with severe CTS., (Copyright © 2016 Elsevier B.V.

Silent brain infarction (SBI) has been considered as a subclinical risk factor for symptomatic possible future stroke. We investigated the association between serum inflammatory markers and SBI. Patients (n = 54) diagnosed with SBI as the study group and 52 individuals as the control group were included in this study. Silent brain infarction is defined as a hyperintense lesion that was ≥3 mm in 1 dimension on fluid-attenuated inversion recovery T2-weighted magnetic resonance image, if the patient had normal neurological examination or had an abnormality that was not consistent with the brain lesion locations, after being evaluated by a neurologist. Serum endocan levels (P =.036) and high-sensitivity C-reactive protein (hsCRP; P =.022) were significantly higher in patients with SBI than the controls. Pentraxin 3, erythrocyte sedimentation rate, white blood count, lymphocyte, monocyte, neutrophil, low-density lipoprotein, and triglyceride levels were not significantly different when comparing the groups with and without SBI. There was a significant correlation (r = −0.196; P =.16) between hsCRP and endocan levels in the SBI group. Endocan, a novel biomarker of endothelial pathology, was significantly increased in patients with SBI and may be useful to predict the future risk of stroke. [ABSTRACT FROM AUTHOR]

Introduction Hypertrophic olivary degeneration (HOD) is a clinical manifestation characterized by the degeneration of the dentato-rubro-olivary tract (Guillain-Mollaret Triangle). Discussion Hypertrophic olivary degeneration (HOD) is a type of trans-synaptic degeneration, which is usually unilateral and occurs due to hypertrophy of the inferior olivary nucleus in response to the damage in dentato-rubro-olivary tract [[1]]. While assessing temporally distributed MRI scans of patients, they detected changes in lesions' appearances and quantities between the first and last MRI scans, and as a result, they have categorized patients into 3 groups as "worsened", "improved", and "unchanged" [[3]].

Objective: Myelopathy is used to describe any neurologic deficit related to the spinal cord. Determining the etiology is important for detecting emergency situations and treating the cause. Materials and Methods: We evaluated 28 patients who were diagnosed as having and treated for myelopathy between January 2014 and January 2015 in our hospital. The clinical and laboratory findings of the patients and their response to treatment were assessed. Results: Of the 28 patients, 16 were male and 12 were female, the mean age was 48 years (range, 22-77 years). The most common initial symptoms were sensorial deficits and motor weakness. Demyelinating diseases were the most common diseases and multiple sclerosis was the most frequent etiology among demiyelinating diseases. Cervical spinal cord was the most frequent region involved in myelopathy episodes which was detected by magnetic resonance imaging on T2W images. We observed clinical improvement in 15 of the 20 patients who were treated with corticosteroids. In addition, vitamin B12 treatment led to clinical improvement in two patients who were diagnosed as having subacute combined degeneration. Conclusion: The diagnosis and etiology of myelopathy and identification of rare conditions that require emergency surgery or interventional treatments are of utmost importance.

Background.—Frequent analgesic drug intake, especially in migraine patients, may induce the risk of medication overuse headache (MOH). The various conditions that may affect the development and the features of MOH have not been determined yet.Aim.—To compare MOH patients with migraine as pre-existing headache and episodic migraine patients according to socioeconomic and educational variables.Methods.—Forty-six MOH patients with migraine as pre-existing headache and 61 migraine patients were included into study. The headache characteristics, socioeconomic and educational variables of MOH and migraine groups and subgroups divided according to the education (low/high education subgroups), and income (low/high income subgroups) levels were evaluated.Results.—We found that mean duration of education was shorter in MOH patients than migraine patients. There was a negative correlation between duration of education and duration of MOH. The mean duration of MOH was longer and rate of low-income level was higher in patients with low-education level. The duration of education was lower in MOH patients with low income. The frequency of migraine attacks and low-income rate was also higher in low-educated migraine patients. The duration of education was shorter in migraine patients with low income.Conclusion.—We report that migraineurs with low socioeconomic status may have risk of developing MOH. A better identification of patients at risk of drug-associated headache may contribute to improved health in a group of patients with MOH.(Headache 2005;45:25-31) [ABSTRACT FROM AUTHOR]
