Traumatic peripheral nerve injuries are among most important cause of physical disability among young adults. Most partial injuries and some complete injuries recover without operative intervention, with early return of function appearing to be the most significant prognostic factor in these cases. Return of function over time depends to a great extent on the underlying neuropathologic condition of the nerve. Although some nerve injuries recover spontaneously, in some cases surgery is the only therapeutic option for the improvement of neurological deficits or control of neuropathic pain. We aimed to review the classification and management of peripheral nerve injury, with emphasize on clinical aspect.Keywords: peripheral nerve, injury, repair

There have been a number of developments in screw design and implantation techniques over recent years, including proposal of an alternative trajectory entitled as cortical bone trajectory (CBT). Cortical bone trajectory has been investigated in recent medical treatments as an alternative for screw fixation aimed at increasing purchase of pedicle screws in higher density bone. CBT screw insertion follows a lateral path in the transverse plane and caudocephalad path in the sagittal plane. This technique has been advocated because it is reportedly less invasive, improves screw−bone purchase and reduces neurovascular injury. Furthermore CBT pedicle screw fixation provides stabilization to multilevel lumbar segment with low-grade spondylolisthesis comparable to the standard trajectory pedicle screw construct. However, these claims have not been supported by robust clinical evidence. Recent investigations focus on evaluations of CBT as a pioneer method.Keywords: cortical, trajectory, osteoporosis, fixation, spinal, fusion

Neurocysticercosis, is the infection caused by the larval form of the tapeworm Taenia solium. It is considered as the most common parasitic disease of the central nervous system and the most common cause of acquired epilepsy. This has primarily been a disease that remains endemic in countries with poor economy , but because of increased migration neurocysticercosis is being diagnosed more frequently worldwide. During the past decades improved diagnostics, imaging, and treatment have led to more accurate diagnosis and improved prognosis for patients. This article is a review about the current data about neurocysticercosis, including recent diagnostics and treatment developments.Keywords: Cysricercosis, epilepsy, tapeworm, CNS

Brain tumors in elderly are increasing as the number of people, who comprise the older population, does.About half of the patients with brain tumors appear to be over 60 years of age.In this review article, Glioblastoma multiform, as the most common malignant tumor of the central nervous system in elderly is discussed in details of definition, prognosis, diagnosis, treatment and differential diagnosis. Other tumors such as meningioma, pituitary adenoma, CNS lymphoma and metastasis are also included to be reviewed. Treatment plans, either conservative or aggressive, classic or novel, approved or under investigation, are presented. Furthermore different attitudes of treatment in the past and recently are also argued. Conventional therapy, Surgery, Radiotherapy, chemotherapy radioimmunotherapy, hormonal therapy and some other novel methods of treatments are discussed in details for the glioma.Determining factors which may be associated to the patient''s response to each treatment planare also discussed. Finally, some age related issues are provided to be paid attention to consider an old patient with brain tumor, and planning an optimal treatment in order to make the best management decisions.Until recently, peoplewith brain tumors in elderly, were used to be treated in conservative plans and often were excluded of the clinical trials but now the number of patients who desire and receive more aggressive therapy for brain tumors is increasing.Keywords: Brain Tumor, elderly, glioblastoma, treatment

BackgroundMotor function impairment occurs in approximately two-thirds of patients with subcortical stroke. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive technique for modulating cortical excitability.ObjectivesThe present study was designed for assessing the efficacy of high-frequency rTMS (5 Hz) on ipsilesional primary motor cortex in patients with subcortical stroke.Materials And MethodsThirty participants who had subcortical stroke in the previous four weeks to four months were enrolled in this randomized double blinded clinical trial. Participants were divided into experimental and control groups and their motor ability of both upper and lower extremities were assessed using Fugl-Meyer assessment of motor recovery after stroke (FMA) before and after intervention. The study intervention rTMS (5 Hz) was administered in six 10-minute sessions on the ipsilesional primary motor cortex in the experimental group and on the vertex in the control group.ResultsMean change in FMA score after rTMS sessions was significantly higher in the experimental group than in the control group (p = 0.00). Mean time interval between the stroke and rTMS intervention had a weak and insignificant (ρ = 0.097; p = 0.61) correlation with changes of FMA score.ConclusionsHigh-frequency (5 Hz) rTMS effectively improved motor function in patients with subcortical stroke.Keywords: Transcranial Magnetic Stimulation, Stroke

BackgroundSeveral studies have shown the prevalence of celiac disease (CD) to be around 1% in Iran, which is similar to the worldwide prevalence. There is scant information on occult CD in apparently healthy school age children. This study, as the first such study in Iran, aims to determine the prevalence of occult CD in healthy Iranian school age children.MethodsIn this cross-sectional study, we screened healthy school age children for CD by serum IgA and IgA anti-tissue transglutaminase antibody (tTG) levels. Measurement of these antibodies was by enzyme linked immunosorbent assay. A recheck of positive tTG tests was performed and patients who tested positive underwent endoscopic duodenal biopsies. The biopsy samples were scored according to the Marsh classification by an experienced pathologist.ResultsA total of 634 children (314 males, 320 females; mean age: 12.8 years) were included in the study. All children and/or their parents completed a questionnaire and children underwent an initial physical examination to determine study eligibility. Positive serum tTG was noted in 3 (0.5%; 2 females) out of 634 patients. Duodenal biopsies were consistent with CD in these 3 subjects. The mean age of patients with CD was 14.3 years (range: 12–17 years). The female to male ratio was 2:1. These cases had no signs and symptoms, but a gluten-free diet was recommended according to pathologic changes in their small bowels and results of the tTG test.ConclusionThe prevalence of occult CD in these children is 0.5%, which is half of the prevalence of CD in Iranian adults. The anti-tTG concentration at initial serological CD screening is highly informative in determining occult cases of CD. The question is whether all non-symptomatic cases should be treated with a gluten-free diet or not.Keywords: Celiac disease, children, Iran, serological screening

Endoscopic sclerotherapy is an effective treatment for bleeding esophageal varices, but it is associated with significant complications. To determine the efficacy and safety of endoscopic sclerotherapy, we evaluated the patients with variceal bleeding who underwent sclerotherapy in our center.Materials And MethodsThis study was a case-series study in which, we evaluated 79 patients who referred for esophageal variceal bleeding and underwent sclerotherapy and completed the questionnaire.ResultsFrom79 patients, 52 (65.8%) weremale, and 27 (34.2%) were female. The rate of success (arrest of acute bleeding by endoscopic sclerotherapy) was 100%, but it was 55.7%for long-termsclerotherapy; 53.3%of patients with liver disease, and 64.7%of patients with extraheaptic portal hypertension had suitable response; 58.3%of patients with ChildA, 83.3%of those with Child B and 14.3%of Child C cirrhotic patients demonstrated appropriate response. In fundal varices, 15.2% were improved, 21.5% were accelerated and 43.3% showed no significant changes. During treatment, 31.6%had one of the complications of sclerotherapy. The rates of rebleeding and mortality were 54.4% and 8.9%, respectively.ConclusionAlthough sclerotherapy reduced themortality attributable to acute variceal bleeding, but the long-term effectiveness of sclerotherapy was not very high.Keywords: Sclerotherapy, Esophageal Varices, Children -
