Carpal tunnel syndrome (CTS) is a most common peripheral nerve entrapment neuropathy characterized by sensorimotor deficits in median nerve innervated digits. Block-design task-related functional magnetic resonance imaging (fMRI) studies have been used to investigate CTS-related neuroplasticity in the primary somatosensory cortices. However, considering the persistence of digital paresthesia syndrome caused by median nerve entrapment, spontaneous neuronal activity might provide a better understanding of CTS-related neuroplasticity, which remains unexplored...

The patient was a 56-year-old man with microscopic polyangiitis and symmetrical peripheral polyneuropathy of the extremities who was positive for p-ANCA, EMG pattern of mononeuritis multiplex and skin biopsy showing the presence of nonspecific vasculitis. He had phlebectasia with plethora and tortuous vessels on dorsum of the fingers on both hands, paresis and hypoesthesia of fingers and toes with functional limitations. The administration of prednisone, azathioprine and a cyclophosphamide pulse achieved rapid improvement in the general symptoms, but the changes in the neuropathy occurred very slowly...

PURPOSE: Carpal tunnel and cubital tunnel syndrome are the 2 most common upper-limb compressive neuropathies. However, whether the characteristics of patient populations undergoing surgery for these conditions are similar is unclear in terms of demographics and concomitant pathologies. Our null hypothesis was that there are no identifiable differences between these patient populations. METHODS: A retrospective cohort study was performed by billing system query using Common Procedural Terminology (CPT) codes for all patients who underwent open carpal tunnel release (CTR) (CPT code 64721) and/or open cubital tunnel surgery (CPT code 64718) by 1 of 4 hand surgeons from August 2008 to July 2013...

BACKGROUND: Isolated stiffness in a single finger can affect the function of adjacent digits and decrease overall hand function due to the quadriga phenomenon. This study objectively quantifies the dysfunctional impact of each individual stiff finger upon the remaining digits. METHODS: Twenty-five individuals (10 men and 15 women) with a mean age of 31 years (range, 18-58 years) without any upper limb pathology, neuropathy, or systemic illness were recruited. Volar-based finger splints were used to hold individual digits of the dominant hand (24 right and 1 left) sequentially in full extension at the metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints...

INTRODUCTION: Ischemic monomelic neuropathy (IMN) is the most dreaded complication of an arteriovenous access creation. While uncommon, it can lead to pain, paresthesia or/and hand weakness. Creation of an arteriovenous connection causing a sudden diversion of blood away from the nerves can lead to ischemic injury to the neural tissue and cause IMN. Immediate surgical ligation has been traditionally recommended to limit ongoing neural tissue injury. CASE DESCRIPTION: We present two diabetic patients who developed IMN after the creation of a left upper extremity brachial-cephalic fistula and refused to undergo surgical ligation...

BACKGROUND: At high altitude, prevalence of restless legs syndrome has been found to be greater than expected in small population-based studies, which did not use validated tools for identification of RLS. However, it is not known as to whether this increased prevalence is associated with altitude or increased risk factors for RLS in these populations or errors in identification of RLS. METHOD: This population based, door-to-door study was conducted at low altitude (400 m above sea level) and high altitudes (1900-2000 m and 3200 m above sea level) using random stratified sampling in Himalayan and sub-Himalayan region of India...

Human podocytes (hPC) are essential for maintaining normal kidney function and dysfunction or loss of hPC play a pivotal role in the manifestation and progression of chronic kidney diseases including diabetic nephropathy. Previously, α-Lipoic acid (α-LA), a licensed drug for treatment of diabetic neuropathy, was shown to exhibit protective effects on diabetic nephropathy in vivo. However, the effect of α-LA on hPC under non-diabetic conditions is unknown. Therefore, we analyzed the impact of α-LA on cell viability and expression of nephrin and zinc finger protein 580 (ZNF580) in normal hPC in vitro...

Paranodal demyelination has been discussed as a potential mechanism of nerve fiber damage in diabetic neuropathy (DNP). Studies on human tissue are limited, as nerve biopsies are invasive and only rarely performed in patients with confirmed DNP. Skin biopsy has recently been suggested as a tool to analyze paranodal and nodal changes of myelinated fibers. We analyzed the myelinated fibers of skin biopsies of 35 patients with DNP, 17 patients with diabetes mellitus (DM) without neuropathy, and 30 normal controls...

PTRH2 is an evolutionarily highly conserved mitochondrial protein that belongs to a family of peptidyl-tRNA hydrolases. Recently, patients from two consanguineous families with mutations in the PTRH2 gene were reported. Global developmental delay associated with microcephaly, growth retardation, progressive ataxia, distal muscle weakness with ankle contractures, demyelinating sensorimotor neuropathy, and sensorineural hearing loss were present in all patients, while facial dysmorphism with widely spaced eyes, exotropia, thin upper lip, proximally placed thumbs, and deformities of the fingers and toes were present in some individuals...
