BACKGROUND: Carpal tunnel syndrome (CTS) can be treated with open carpal tunnel release (OCTR) or endoscopic carpal tunnel release (ECTR). Our goal was to evaluate the safety and efficacy of ECTR versus OCTR in patients with severe CTS. We hypothesized that ECTR would be as safe and effective as OCTR in these patients. METHODS: This was a retrospective cohort study of patients with severe CTS who underwent ECTR or OCTR by E. G. Deune between 2001 and 2014. Variables were patient age, sex, relevant medical history, alcohol and tobacco use, and preoperative electromyography and physical examination results...

Charcot arthropathy is defined as an articular degenerative, chronic, progressive disease that affects one or more peripheral joints, develops as a result of a failure in the normal sensory perception (pain and proprioception) in the innervation of joints located in the foot and ankle, is characterized by destructive bone lesions without the presence of infection. Neuropathy is directly associated with diabetes mellitus type 1 and 2. Surgery is indicated when there is severe involvement of soft tissue, foot joints are unstable, at the presence of chronic or recurrent ulcers or when the foot and ankle can not fit to a normal shoe, and had limitation to perform activities of daily living...

Mutations in the gap junction protein beta 1 gene (GJB1) cause X-linked Charcot-Marie-Tooth disease type 1 (CMTX1). CMTX1 is representative of the intermediate type of CMT, having both demyelinating and axonal neuropathic features. We analyzed the clinical and genetic characterization of 128 patients with CMTX1 from 63 unrelated families. Genetic analysis revealed a total of 43 mutations including 6 novel mutations. Ten mutations were found from two or more unrelated families. p.V95M was most frequently observed...

How organisms sense and respond to noxious temperatures is still poorly understood. Further, the mechanisms underlying sensitization of the sensory machinery, such as in patients experiencing peripheral neuropathy or injury-induced sensitization, are not well characterized. The genetically tractable Drosophila model has been used to study the cells and genes required for noxious heat detection, which has yielded multiple conserved genes of interest. Little is known however about the cells and receptors important for noxious cold sensing...

Michael P Collins, Robert D Hadden
Nonsystemic vasculitic neuropathy (NSVN) is an under-recognized single-organ vasculitis of peripheral nerves that can only be diagnosed with a nerve biopsy. A Peripheral Nerve Society guideline group published consensus recommendations on the classification, diagnosis and treatment of NSVN in 2010, and new diagnostic criteria for vasculitic neuropathy were developed by the Brighton Collaboration in 2015. In this Review, we provide an update on the classification, diagnosis and treatment of NSVN. NSVN subtypes include Wartenberg migratory sensory neuropathy and postsurgical inflammatory neuropathy...

Epalrestat is clinically applied for the management of diabetic peripheral neuropathy, yet its pharmacokinetic properties are not well understood. In this study, a rapid and sensitive LC-MS/MS method was established for assaying epalrestat in bio-samples of mice. The method was validated and it showed a good linearity over the range of 2-5000ng/mL, a precision of less than 12.3%, and recovery and matrix effects of 112.5-123.6% and 87.9-89.5%, respectively. After administration of a single dose of epalrestat administered, the exposure level of AUC0-∞ was positively dose-dependent and the mean Cmax, AUC0-12h, T1/2, and MRT were 36...

Purpose: Benzalkonium chloride (BAK) is the most commonly used eye drop preservative. Benzalkonium chloride has been associated with toxic effects such as "dry eye" and trabecular meshwork degeneration, but the underlying biochemical mechanism of ocular toxicity by BAK is unclear. In this study, we propose a mechanistic basis for BAK's adverse effects. Method: Mitochondrial O2 consumption rates of human corneal epithelial primary cells (HCEP), osteosarcoma cybrid cells carrying healthy (control) or Leber hereditary optic neuropathy (LHON) mutant mtDNA [11778(G>A)], were measured before and after acute treatment with BAK...

INTRODUCTION    Diabetic foot (DF) is a devastating complication of diabetes mellitus (DM) that occurs due to neuropathy and/or atherosclerosis of the lower limbs. Omentin (encoded by the ITLN1 gene) has been implicated as a protective factor in vascular complications of diabetes, likely due to its endothelial vasodilator activity and its anti-inflammatory actions. However, susceptibility to DF in terms of ITLN1 gene polymorphisms has not been studied. OBJECTIVES    This study aimed to evaluate the association between ITLN1 gene polymorphism rs2274907and the occurrence of DF in patients with type 2 diabetes mellitus (T2DM)...
