Polyneuropathy is a prevalent and disabling disorder. Despite extensive evaluation, the cause often remains unknown. Factors that predispose for the development of polyneuropathy need to be identified. We investigated the effect of anthropometric and metabolic factors on peripheral nerve function in 908 participants of the population-based Rotterdam Study without any symptoms or signs of polyneuropathy. Participants underwent nerve conduction studies of the sural and peroneal nerve. Data on age, height, weight, waist circumference, diabetes, lipid levels, hypertension and kidney function were collected...

PURPOSE: Identification of modifiable risk factors for falling is paramount in reducing the incidence and morbidity of falling. Peroneal neuropathy with an overt foot drop is a known risk factor for falling, but research into subclinical peroneal neuropathy (SCPN) resulting from compression at the fibular head is lacking. The purpose of our study was to determine the prevalence of SCPN in hospitalized patients and establish whether it is associated with a recent history of falling. METHODS: We conducted a cross-sectional study of 100 medical inpatients at a large academic tertiary care hospital in St Louis, Missouri...

INTRODUCTION: Coir work, in a large number of people involves mechanically rolling the coconut fibers into coir which is later subjected to various processes. The primary work is done as a cottage industry specially by women in the sitting posture for several hours. This study reports evidence of median and common peroneal neuropathy electrophysiologically in people who had been engaged in this job for several years. This study was initiated to establish the possible relationship between coir work and symptomatic neuropathies which was seen in that region with all investigations "for other causes not" contributing to the etiological diagnosis...

Perioperative compression neuropathy is a known potential complication of prolonged surgical procedures. Sciatic postoperative neuropathy has rarely been reported. We present a 34-year-old woman who underwent right breast reconstruction with supercharged (venous anastomosis) transverse rectus abdominis flap and developed bilateral sciatic compression neuropathy. Her history was remarkable for sleeve gastrectomy 2 years earlier resulting in 105 pound weight loss 1 year before breast reconstruction. During the procedure, the patient was in the supine position for 8 hours and in the semirecumbent position for an additional 2 hours with the torso flexed at 30 degrees and knees flexed at approximately 45 degrees in addition to standard padding...

Distal hereditary motor neuropathies (dHMN) are a group of rare hereditary neuromuscular disorders characterized by an atrophy that affects peroneal muscles in the absence of sensory symptoms. To date, 23 genes are thought to be responsible for dHMN, four of which encode chaperones: DNAJB2, which encodes a member of the HSP40/DNAJ co-chaperone family; and HSPB1, HSPB3, and HSPB8, encoding three members of the small heat shock protein family. While around 30 different mutations in HSPB1 have been identified, the remaining three genes are altered in many fewer cases...

OBJECTIVE: In the very elderly, their general condition and poor compliance with drug regimens can render the treatment of low back pain (LBP) difficult. We report the effectiveness of a less-invasive treatment for intractable LBP from superior cluneal nerve entrapment neuropathy (SCN-EN) and gluteus medius muscle (GMeM) pain. PATIENTS AND METHODS: Between April 2013 and March 2015, we treated 17 consecutive elders with LBP, buttock pain, and leg pain. They were 4 men and 13 women ranging in age from 85 to 91 years (mean 86...

Recently published studies show that the prevalence of polyneuropathy (PNP) is higher in patients with Parkinson's disease (PD) than in age-matched controls. Its pathogenesis, however is a matter of controversy. The major hypothesis is the toxicity of high concentrations of homocysteine (Hcy) possibly related to levodopa (LD) therapy. The aim of the present study was to determine the prevalence of PNP, independent of other etiologies, and to determine the relationship to demographic and clinical factors in LD-treated Parkinson's patients...
