Isolated paralysis of hypoglossal nerve is uncommon, generally being associated with other neuropathies. A careful differential diagnosis is necessary to recognize the underlying diseases, some of which can be life-threatening. The authors report a patient of an 80-year-old woman presenting with an isolated hypoglossal palsy, mimicking a tongue neoplasm. Through a careful clinical workup and thanks to the aid of the imaging, it was possible to identify the presence of signal alterations due to a subacute denervation of the affected hemitongue and to exclude the presence of a tumor...

In addition to the more common carpal tunnel and cubital tunnel syndromes, orthopaedic surgeons must recognize and manage other potential sites of peripheral nerve compression. The distal ulnar nerve may become compressed as it travels through the wrist, which is known as ulnar tunnel or Guyon canal syndrome. The posterior interosseous nerve may become entrapped in the proximal forearm as it travels through the radial tunnel, which results in a pain syndrome without motor weakness. The median nerve may become entrapped in the proximal forearm, which can result in a variety of symptoms...

Knowledge of diabetic Charcot neuroarthropathy (DCN) has grown tremendously since this condition was first described in 1936 by William Riely Jordan. Despite advancements in diagnostic approaches and treatment options making DCN limb salvage a more viable option, ongoing and additional research is needed to determine the definitive pathogenesis, which may aid in prevention of the condition. This article chronicles the main developments for the study and management of DCN since 1936 and recommends using the term diabetic Charcot-Jordan foot when specifically managing foot and ankle neuroarthropathy joints in patients with diabetic neuropathy...

BACKGROUND: Guillain-Barré syndrome (GBS) is an immune-mediated neuropathy that causes acute flaccid paralysis. Immunoglobulin and plasma exchange are established treatments for GBS; however, a substantial number of patients, particularly those with severe disease, have poor recovery and residual deficits. Recent studies suggest that complement activation plays a pivotal role in GBS-associated axonal degeneration, and eculizumab is a humanized monoclonal antibody that specifically binds to complement component 5 and potently inhibits complement activation...

OBJECTIVE: Chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating side-effect of chemotherapy. However, CIPN symptoms are also reported by patients not receiving chemotherapy. Normative data could help interpret CIPN among cancer patients. Our aim was to generate normative data for the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-CIPN20 Questionnaire designed to assess CIPN from the patients' perspective. The normative CIPN data have also been generated for stratified subgroups formed on the basis of sex, age and comorbidity...

OBJECTIVES: The purpose of the study was to explore the effect of intensity on speech perception in individuals with late-onset auditory neuropathy spectrum disorder (ANSD) by obtaining their performance-intensity (PI) function. Additionally, the study investigated the effect of PI function on aided speech perception. It was hypothesized that speech perception abilities of individuals with ANSD vary with intensity and may provide information regarding their aided performance. DESIGN: A factorial research design was used to obtain the PI function and aided performance...

Mark F McCarty
In type 1 diabetics, hepatic exposure to insulin is chronically subnormal even in the context of insulin therapy; as a result, expression of glycolytic enzymes is decreased, and that of gluconeogenic enzymes is enhanced, resulting in a physiologically inappropriate elevation of hepatic glucose output. Subnormal expression of glucokinase (GK) is of particular importance in this regard. Possible strategies for correcting this perturbation of hepatic enzyme expression include administration of small molecule allosteric activators of GK, as well as a procedure known as chronic intermittent intravenous insulin therapy (CIIIT); however, side effects accompany the use of GK activators, and CIIIT is time and labor intensive...

South Africa has one of the highest prevalences of HIV and AIDS in the world. HIV/AIDS patients face countless challenges, one of which is the risk of adverse drug reactions (ADRs). This study aimed to describe the ADRs reported in South Africa with reference to the type of ADRs, antiretrovirals (ARVs) implicated, seriousness of the ADRs and patient demographics associated with specific ADRs. A retrospective quantitative study was carried out using ADR reports submitted to the National Department of Health (NDoH) from 1 January 2010 to 31 December 2014...

Ana Rocha, Luísa Lobato
Orthotopic liver transplantation (LT) was implemented as the inaugural disease-modifying therapy for hereditary transthyretin (ATTR) amyloidosis, a systemic amyloidosis mainly affecting the peripheral nervous system and heart. The first approach to pharmacologic therapy was focused on the stabilization of the TTR tetramer; following that new advent LT was assumed as the second step of treatment, for those patients whose neuropathy becomes worse after a course of pharmacologic therapy. The renal disease has been ignored in hereditary ATTR amyloidosis...

REVIEW
Bryan G Beutel, Scott D Lifchez, Eitan Melamed
BACKGROUND: Cardiovascular procedures are common and are trending toward endovascular interventions. With this increase in endovascular procedures, there is also increasing awareness of upper extremity morbidity resulting from treatment. METHODS: Articles indexed within PubMed between the years 1975 and 2015 that discussed such complications were reviewed. RESULTS: Percutaneous radial artery access can lead to nerve ischemia, especially in the setting of an incomplete arterial arch, whereas radial artery harvesting for bypass surgery more commonly causes frank tissue ischemia and radial neuropathy...

With the introduction of newborn hearing screening, infants are being diagnosed with hearing loss during the first few months of life. For infants with a sensory/neural hearing loss (SNHL), the audiogram can be estimated objectively using auditory brainstem response (ABR) testing and hearing aids prescribed accordingly. However, for infants with auditory neuropathy spectrum disorder (ANSD) due to the abnormal/absent ABR waveforms, alternative measures of auditory function are needed to assess the need for amplification and evaluate whether aided benefit has been achieved...

Diabetes is a chronic disease, and its prevalence continues to rise and can increase the risk for the progression of microvascular (such as nephropathy, retinopathy and neuropathy) and also macrovascular complications. Diabetes is a condition in which the oxidative stress and inflammation rise. Heat shock proteins (HSPs) are a highly conserved family of proteins that are expressed by all cells exposed to environmental stress, and they have diverse functions. In patients with diabetes, the expression and levels of HSPs decrease, but these chaperones can aid in improving some complications of diabetes, such as oxidative stress and inflammation...

BACKGROUND: Neurosarcoidosis occurs in fewer than 5% of adults with systemic sarcoid. However, only 53 examples of neurosarcoidosis have been reported in the pediatric population, with nine of those cases being isolated neurosarcoidosis. We present the tenth case of a child with an initial presentation of isolated neurosarcoidosis and a review of the literature. METHODS: We searched the Ovid Medline database from 1946 to May 28, 2015. The Mesh terms "neurosarcoidosis," "pediatric," and "child" were exploded, and the Boolean "AND" was used to combine "neurosarcoidosis" with "pediatric" or "child...

The Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyneuropathy (CIDP) are the most common immune-mediated polyneuropathies, which can show variable clinical and electrophysiological manifestations. Rarer immune-mediated neuropathies encompass paraproteinemic neuropathies (PPN), multifocal motor neuropathy (MMN) and vasculitic neuropathies. The diagnosis usually relies on the history of symptom evolution, distribution of nerve dysfunction and particularly on characteristic features in nerve conduction studies, aided by cerebrospinal fluid (CSF) examination and nerve biopsy findings...

BACKGROUND: Acute flaccid weakness may be the first presentation of acute transverse myelitis (ATM), an immune-mediated central nervous system disorder or may be the first presentation of anterior horn cell syndrome or peripheral nervous system disease. CASE REPORTS: We describe two previously healthy female infants who presented with acute flaccid paralysis and encephalopathy. Neuroimaging revealed central cord signal changes in both cases and surprisingly electrophysiological studies performed revealed a generalized axonal motor neuropathy as well...
