REVIEW
K Co Shih, K S-L Lam, L Tong
Diabetes mellitus is associated with extensive morbidity and mortality in any human community. It is well understood that the burden of diabetes is attributed to chronic progressive damage in major end-organs, but it is underappreciated that the most superficial and transparent organ affected by diabetes is the cornea. Different corneal components (epithelium, nerves, immune cells and endothelium) underpin specific systemic complications of diabetes. Just as diabetic retinopathy is a marker of more generalized microvascular disease, corneal nerve changes can predict peripheral and autonomic neuropathy, providing a window of opportunity for early treatment...

Aims. To compare optical coherence tomography angiography (OCT-A) retinal vasculature measurements between normal and optic atrophy after nonarteritic anterior ischemic optic neuropathy (NAION) subjects. Design. This prospective observational study was conducted between July 2015 and August 2016 at the ophthalmology outpatient department of a referral center in Taiwan. Peripapillary (4.5 × 4.5 mm) and parafoveal (6 × 6 mm) OCT-A scans were acquired. Measurements of the peripapillary region were obtained in two areas: (1) circumpapillary vessel density (cpVD) and (2) whole enface image vessel density (wiVD)...

PURPOSE: A diagnostic maneuver known as the "scratch-collapse test" (SCT), to aid in the diagnosis of compressive upper limb neuropathies such as carpal tunnel syndrome (CTS), has been described. There is a wide variability in the sensitivity and specificity values reported to date, and the reason for this discrepancy is unclear. The purpose of this study was to evaluate the utility of the SCT performed by examiners blinded to the meaning of the examination. METHODS: Forty consecutive patients referred to a single physiatrist for electrodiagnostic testing for the evaluation of suspected CTS were included in the study...

Peripheral neuropathies are frequent and can mostly be correctly diagnosed by clinical examination and electrophysiology; however, diagnostically difficult cases are sometimes encountered especially with respect to precise localization of nerve lesions. Imaging of the peripheral nervous system has been shown to provide additional useful diagnostic information. In addition to the more widely available nerve sonography, magnetic resonance neurography (MRN) is the method of choice in diagnostically complex cases...

Chemotherapy-induced peripheral neuropathy (CIPN) is a major, dose-limiting adverse effect experienced by cancer patients. Advancements in mechanism-based risk mitigation and effective treatments for CIPN can be aided by suitable in vitro assays. To this end, we developed a multiparametric morphology-centered rat dorsal root ganglion (DRG) assay. Morphologic alterations in subcellular structures of neurons and non-neurons were analyzed with an automated microscopy system. Stains for NeuN (a neuron-specific nuclear protein) and Tuj-1 (β-III tubulin) were used to identify neuronal cell nuclei and neuronal cell bodies/neurites, respectively...

CLINICAL/METHODICAL ISSUE: Up to the advent of high-resolution ultrasound, interventions on the peripheral nervous system, including local anesthesia and pain treatment were performed without visual guidance, which in some cases led to treatment failure or local tissue and nerve damage. METHODICAL INNOVATIONS: Progress in the field of ultrasound has enabled the functional visualization, anesthesia and anti-inflammatory or neurolytic treatment of many peripheral nerves, such as the brachial plexus, nerves of the upper and lower extremities and various nerves of the trunk...

Penile erection requires complex interaction between vascular endothelial cells, smooth muscle cells, pericytes, and autonomic nerves. Diabetes mellitus is one of the most common causes of erectile dysfunction (ED) and multiple pathogenic factors, such as cavernous angiopathy and autonomic neuropathy, are associated with diabetic ED. Although a variety of animal models of diabetic ED play an important role in understanding pathophysiologic mechanisms of diabetes-induced ED, these animal models have limitations for addressing the exact cellular or molecular mechanisms involved in ED...

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...
