Rasch‐built Overall Disability Scale for Multifocal motor neuropathy (MMN‐RODS©)
Abstract Clinical trials in MMN have often used ordinal‐based measures that may not accurately capture changes. We aimed to construct a disability interval outcome measure specifically for MMN using the Rasch model and to examine its clinimetric properties. A total of 146 preliminary activity and participation items were assessed twice (reliability studies) in 96 clinically stable MMN patients. These patients also assessed the ordinal‐based overall‐disability sum‐score (construct, sample‐dependent validity). The final Rasch‐built overall‐disability scale for MMN (MMN‐RODS©) was serially applied in 26 patie...

Safety and efficacy of ranirestat in patients with mild‐to‐moderate diabetic sensorimotor polyneuropathy
We examined the efficacy and safety of ranirestat in patients with diabetic sensorimotor polyneuropathy (DSPN). Patients (18–75 years) with stable type 1/2 diabetes mellitus and DSPN were eligible for this global, double‐blind, phase II/III study (ClinicalTrials.gov NCT00927914). Patients (n=800) were randomized 1:1:1 to placebo, ranirestat 40 mg/day or 80 mg/day (265:264:271). Change in peroneal motor velocity (PMNCV) from baseline to 24 months was the primary endpoint with a goal improvement vs. placebo ≥1.2 m/s. Other endpoints included symptoms, quality‐of‐life, and safety. 633 patients completed the stud...

Systematic review of exercise for Charcot‐Marie‐Tooth disease
Abstract Charcot‐Marie‐Tooth disease (CMT) is a slowly progressive hereditary degenerative disease and one of the most common neuromuscular disorders. Exercise may be beneficial to maintain strength and function for people with CMT, however, no comprehensive evaluation of the benefits and risks of exercise have been conducted. A systematic review was completed searching numerous electronic databases from earliest records to February 2015. Studies of any design including participants of any age with confirmed diagnosis of CMT that investigated the effects of exercise were eligible for inclusion. Of 13,301 articles ident...

Patterns and severity of vincristine‐induced peripheral neuropathy in children with acute lymphoblastic leukemia
Abstract Vincristine, a critical component of combination chemotherapy treatment for pediatric acute lymphoblastic leukemia (ALL), can lead to vincristine‐induced peripheral neuropathy (VIPN). Longitudinal VIPN assessments were obtained over 12 months from newly diagnosed children with ALL (N=128) aged 1–18 years who received vincristine at one of four academic children's hospitals. VIPN assessments were obtained using the Total Neuropathy Score‐Pediatric Vincristine (TNS©‐PV), National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE©), Balis© grading scale, and Pediatric Neuropathic Pain ...

When is facial diplegia regarded as a variant of Guillain‐Barré syndrome?
This study aimed to characterize and determine the incidence of this FD‐predominant GBS variant. The clinical and serological information of 900 consecutive patients were reviewed. In total, eight patients were identified between January 2007 and December 2010 as having FD accompanied by some features of GBS. These features were subjective sensory symptoms such as distal paresthesia (7/8, 88%), albumin‐cytological (A/C) dissociation (7/8, 88%), antecedent infection (6/8, 75%), and minor nerve conduction study (NCS) abnormalities (5/7, 71%). One patient presented with the typical NCS feature of demyelinating neuropathy....

Genetic determinants of chronic oxaliplatin‐induced peripheral neurotoxicity: a genome‐wide study replication and meta‐analysis
Abstract We aimed at validating the role of genetic variants identified by a recent genome‐wide association study as determinants of chronic oxaliplatin‐induced peripheral neurotoxicity (OXAIPN). Eight polymorphisms (rs10486003, rs2338, rs843748, rs797519, rs4936453, rs12023000, rs17140129, rs6924717) were genotyped in a total of 150 colorectal cancer patients of Caucasian origin receiving oxaliplatin‐based chemotherapy. The severity grade of chronic OXAIPN was assessed by NCI‐CTC criteria and the clinical version of the Total Neuropathy Score© (TNSc©). None of the polymorphisms investigated was found associated ...

CIDP‐like neuropathies in graft versus host disease
This study reviews the literature data and reports one additional case. Materials and MethodsA systematic review of the CIDP‐like neuropathies associated with GVHD was conducted until January 2015, analyzing the clinical presentation and the response to different therapeutic regimens. ResultsNineteen patients with CIDP‐like neuropathies associated with GVHD have been reported in literature including the present one. Fourteen subjects fulfilled the criteria for CIDP, while two cases presented with an asymmetric motor onset and one showed motor involvement only associated with anti‐ganglioside antibodies. In addition, ...

Effect of diet induced obesity or type 1 or type 2 diabetes on corneal nerves and peripheral neuropathy in C57Bl/6J mice
Abstract We determined the impact diet induced obesity (DIO) and types 1 and 2 diabetes has on peripheral neuropathy with emphasis on corneal nerve structural changes in C57Bl/6J mice. Endpoints examined included nerve conduction velocity, response to thermal and mechanical stimuli and innervation of the skin and cornea. DIO mice and to a greater extent type 2 diabetic mice were insulin resistant. DIO and both types 1 and 2 diabetic mice developed motor and sensory nerve conduction deficits. In the cornea of DIO and type 2 diabetic mice there was a decrease in sub‐epithelial corneal nerves, innervation of the corneal epi...

Improving assessment in small fiber neuropathy
In conclusion, the 32‐item SFN‐RODS© is a disease‐specific interval measure suitable for detecting activity limitations and participation restrictions in patients with SFN. The 13‐item SFN‐SIQ© was transformed through Rasch to an interval measure. The use of these scales is recommended in future clinical interventional trials involving patients with SFN.

Comparing the NIS vs MRC and INCAT sensory scale through Rasch analyses
Abstract We performed a comparison between NISsensory versus the mISS, and NISmotor versus the MRCsumscore in patients with Guillain‐Barré syndrome (GBS), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and IgM monoclonal gammopathy of undetermined significance related polyneuropathy (MGUSP). The ordinal data were subjected to Rasch analyses, creating Rasch‐transformed (RT)‐intervals for all measures. Comparison between measures was based on validity/reliability with an emphasis on responsiveness (using the patient's level of change related to the individually obtained varying standard errors for m...
