Purpose This study evaluates the hypothesis that bipolar stimulation of the S3 and S4 sacral roots may enhance the efficacy of the percutaneous nerve evaluation (PNE) test. Material and Methods In this case-control-study, we enrolled 43 patients undergoing bipolar PNE and 57 controls undergoing unipolar PNE. For bipolar PNE, four test electrodes were placed at the bilateral S3 and S4 roots. The electrodes at the S3 and S4 roots of each side were connected to obtain bipolar stimulation. The test protocol over eight days included unilateral and bilateral stimulation of the S3 and S4 sacral roots...

Short Tandem Repeats (STRs) are frequent entities in many transcripts, however, in some cases, pathological events occur when a critical repeat length is reached. This phenomenon is observed in various neurological disorders, such as myotonic dystrophy type 1 (DM1), fragile X-associated tremor/ataxia syndrome, C9orf72-related amyotrophic lateral sclerosis and frontotemporal dementia (C9ALS/FTD), and polyglutamine diseases, such as Huntington's disease (HD) and spinocerebellar ataxias (SCA). The pathological effects of these repeats are triggered by mutant RNA transcripts and/or encoded mutant proteins, which depend on the localization of the expanded repeats in non-coding or coding regions...

Epilepsy is one of the most common neurological disorders. To the best of our knowledge, in Italy, the relationship between patients' and caregivers' psychological state has rarely been analyzed. Thus, we sought to evaluate both the psychological state of patients with epilepsy and that of their caregivers and the interrelationship between them. We also assessed the existing relation between psychological features and some clinical and demographic information, such as number of antiepileptic drugs (AEDs), epilepsy duration and education level of patients and their caregivers...

BACKGROUND: Incarcerated medial epicondyle fractures in association with elbow trauma are rare and an absolute indication for intervention. Because of the infrequent nature, outcomes following this injury are not well documented. We studied a large cohort of these injuries to determine factors associated with functional outcomes. It was hypothesized that a greater duration between initial presentation and time of surgery would lead to poorer outcomes. METHODS: A total of 32 patients aged 18 and under who underwent surgical treatment for an incarcerated medical epicondyle fracture at a level-1 pediatric trauma center from 2003 to 2015 were identified...

Cockayne syndrome (CS) is a rare autosomal recessive disorder characterized principally by progressive growth failure, neurologic abnormality and premature aging. Mutations of excision repair cross‑complementation group 6 (ERCC6) and ERCC8 are predominantly responsible for CS, of which mutation of ERCC6 accounts for approximately two thirds of cases. The current report describes two siblings with severe neurologic abnormality and premature aging. Whole exome sequencing identified two novel mutations in ERCC6 that had not been previously reported...

Global Cerebral Ischemia (GCI) occurs following cardiac arrest or neonatal asphyxia and leads to harmful neurological consequences. In most cases, patients who survive cardiac arrest develop severe cognitive and motor impairments. This study focused on learning and memory deficits associated with brain neuroanatomical reorganization that appears after GCI. The four-vessel occlusion (4VO) model was performed to produce a transient GCI. Hippocampal lesions in ischemic rats were visualized using anatomical Magnetic Resonance Imaging (aMRI)...

STUDY DESIGN: Retrospective chart review. OBJECTIVE: To determine the long-term efficacy of 2-stage total en bloc spondylectomy (TES). SUMMARY OF BACKGROUND DATA: TES is a well-described technique to achieve tumor-free margins, but it is a highly destabilizing procedure that necessitates spinal reconstruction. A 2-stage anterior/posterior approach for tumor resection and instrumentation has been shown to be biomechanically superior to the single-stage approach in achieving rigid fixation, but few clinical studies with long-term outcomes exist...

STUDY DESIGN: Systematic review. OBJECTIVES: We conducted a systematic review of the literature to answer the following questions regarding the use of steroid therapy in metastatic spinal cord compression (MSCC): 1. In cases of MSCC, what is the effect of steroid administration before definitive radiotherapy or surgery on ambulatory status, bowel and bladder function and survival? 2. What steroid dosing regimens are associated with the best outcomes concerning neurological symptoms and complication prevention in cases of MSCC? SUMMARY OF BACKGROUND DATA: Currently, there is significant variation in the initial bolus dose, daily maintenance dose and duration of treatment when steroids are used as a bridge to definitive therapy for MSCC...

INTRODUCTION: Spinal epidural abscess (SEA) is a rare but serious cause of back pain in the critical care setting. It occurs most commonly in adults in their fifth and sixth decades of life. Risk factors include diabetes mellitus, alcoholism, AIDS or other immunocompromised states, cancer, intravenous drug use, trauma and spinal surgery. The clinical presentation can be non-specific but the classical triad includes back pain, fever and neurological deficits. Magnetic resonance imaging (MRI) with gadolinium is the diagnostic imaging modality of choice...

Children with hemoglobin SC (HbSC) disease suffer a significant incidence of silent cerebral infarcts but stroke is rare. A 2-year-old African American boy with HbSC disease presented with focal neurologic deficits associated with magnetic resonance imaging evidence of cerebral infarction with vascular abnormalities. After the acute episode he was treated with monthly transfusions and subsequently transitioned to hydroxyurea therapy. The benefits of hydroxyurea as a fetal hemoglobin inducer in HbSC disease, to ameliorate clinical symptoms are supported by retrospective studies...

Mental, neurological and substance use (MNS) disorders represent a major source of disability and premature mortality worldwide. However, in developing countries patients with MNS disorders are often poorly managed and treated, particularly in marginalized, impoverished areas where the mental health gap and the treatment gap can reach 90%. Efforts should be made in promoting help by making mental health care more accessible. In this article, we address the challenges that psychological and psychiatric services have to face in a low-resource context, taking our experience at a Moroccan rehabilitation center as a case study...
