Background context Epidural fibrosis is a major challenge in spine surgery, with some patients having recurrent symptoms secondary to excessive formation of scar tissue resulting in neurologic compression. One of the most important factors initiating the epidural fibrosis is assumed to be the transforming growth factor-1β (TGF-1β). Rosuvastatin (ROS) has shown to demonstrate preventive effects over fibrosis via inhibiting the TGF-1β. Purpose We hypothesized that ROS might have preventive effects over epidural fibrosis through the inhibition of TGF-1β pathways. Study design Experimental animal study. Methods Forty-eight adult male Wistar Albino rats were equally and randomly divided into four groups (laminectomy, spongostan, topical ROS, and systemic ROS). Laminectomy was performed at the L3 level in all rats. Four weeks later, the extent of epidural fibrosis was assessed both macroscopically and histopathologically. Results Our data revealed that topical application and systemic administration of ROS both were effective in reducing epidural fibrosis formation. Furthermore, the systemic administration of ROS yielded better results than topical application. Conclusions Both topical application and systemic administration of ROS show meaningful preventive effects over epidural fibrosis through multiple mechanisms. The results of our study provide the first experimental evidence of the preventive effects of ROS over epidural fibrosis. © 2015 Elsevier Inc. Source

Aim: Previous studies demonstrated the neuroprotective effects of testosterone, but no previous study has examined the neuroprotective effects of testosterone on spinal cord ischemia/reperfusion injury. The purpose of this study was to evaluate whether testosterone could protect the spinal cord from ischemia/reperfusion injury. Methods: Rabbits were randomised into four groups of eight animals as follows: group 1 (control), group 2 (ischemia), group 3 (methylprednisolone) and group 4 (testosterone). In the control group only a laparotomy was performed. In all other groups, the spinal cord ischemia model was created by the occlusion of the aorta just caudal to the renal artery. Levels of malondialdehyde and catalase were analysed, as were the activities of caspase-3, myeloperoxidase, and xanthine oxidase. Histopathological and ultrastructural evaluations were performed. Neurological evaluation was performed with the Tarlov scoring system. Results: After ischemia-reperfusion injury, increases were found in caspase-3 activity, myeloperoxidase activity, malondialdehyde levels, and xanthine oxidase activity. In contrast, decreases in catalase levels were observed. After the administration of testosterone, decreases were observed in caspase-3 activity, myeloperoxidase activity, malondialdehyde levels, and xanthine oxidase activity, whereas catalase levels increased. Furthermore, testosterone treatment showed improved results concerning histopathological scores, ultrastructural score and Tarlov scores. Conclusions: Our results revealed for the first time that testosterone exhibits meaningful neuroprotective activity following ischemia-reperfusion injury of the spinal cord. © 2014 Elsevier Ltd.

Helicobacter pylori (H. pylori) is a prevalent, worldwide, chronic infection. Choice of treatment can be modified according to antibiotic-resistance rates of H. pylori. The ideal therapeutic regimen for H. pylori infection should achieve an eradication rate of ≥ 80%. In some countries, triple therapy with a proton-pump inhibitor (PPI), clarithromycin, and amoxicillin or metronidazole is still the best option. Bismuth-containing quadruple therapy consisting of bismuth salts, tetracycline, metronidazole and PPI, may be the preferred option in countries with clarithromycin resistance > 20%. Sequential therapy including a PPI and amoxicillin given for the first 5 d, followed by triple therapy including a PPI, clarithromycin, and nitroimidazole antimicrobial (all twice daily) for the remaining 5 d, can be another option for the first-line treatment of H. pylori. Recent data suggest that treatment with PPI, levofloxacin, and amoxicillin for 10 d is a good choice for second-line therapy. Concomitant therapy consisting of PPI, amoxicillin, clarithromycin and metronidazole is another option for second-line treatment. If second-line treatment also fails, it is recommended to culture H. pylori from biopsy specimens and perform antimicrobial susceptibility testing. Rescue treatment should be based on antimicrobial susceptibility. © 2014 Baishideng Publishing Group Co., Limited. All rights reserved. Source

The lateral pectoral nerve (LPN) is commonly injured along with the brachial plexus, but its isolated lesions are rare. Here, we present a case of an isolated LPN lesion confused with cervical radiculopathy. A 41-year-old man was admitted to our clinic because of weakness in his right arm. Previous magnetic resonance imaging (MRI) examination revealed right posterolateral protrusion at the C6-7 level. At the initial assessment, atrophy of the right pectoralis major muscle was evident, and mild weakness of the right shoulder adductor, internal rotator, and flexor muscles was observed. Therefore, electrodiagnostic evaluation was performed, and a diagnosis of isolated LPN injury was made. Nerve injury was thought to have been caused by weightlifting exercises and traction injury. Lateral pectoral nerve injury can mimic cervical radiculopathy, and MRI examination alone may lead to misdiagnosis. Repeated physical examinations during the evaluation and treatment phase will identify the muscle atrophy that occurs 1 or more months after the injury. Copyright © 2014 Wolters Kluwer Health, Inc.

Objective: Stigma associated with epilepsy has negative effects on psychosocial outcomes, affecting the lives of people with epilepsy (PWE). Obtaining basic social rights can be difficult compared to the general population. The aim of our study was to evaluate the perceived stigma among PWE and social attitude towards the disease and to compare the social measures with the general population in Turkey. Method: A self-completed questionnaire consisting of demographic details and items about attitudes and perceived stigmatization was developed. Participants consisted of patients with various types of seizures who were randomly chosen from the epilepsy outpatient clinic. They were requested to complete the questionnaire. Results: Questionnaires were obtained from 330 PWE. One hundred forty individuals (43.3%) out of 323 reported feeling stigmatized.The marriage and total fertility rates were below the national rates of Turkey. Keeping their epilepsy as a secret from society was prevalent. Although the education rate was not below the national rate, unemployment rate was high, and the average monthly wage was significantly lower than that of the general population.The majority thought that their families were protective towards them. Only 2 of the 330 participants were living alone. Conclusion: The present study supports the perception of stigma associated with epilepsy and its negative impact on the lives of PWE in Turkey. Clearly, more research is needed to understand the reasons for stigma and how to decrease its impact. © 2015 Elsevier Inc.. Source
