Human dental stem cells (hDSC) have a potential for regenerative therapies and could differentiate in vitro into many tissues such as dentin, nerve and vascular endothelium. Gallus gallus domesticus developing fertilized egg, or chick embryo is an experimental model absent of xenografts rejection, largely employed in replacement of mammal species in scientific research and pre-clinical studies to evaluate angiogenesis and vasculogenesis, tissue differentiation, and embryonic development. This multiscale research deals with the homing and cell signaling effects of a standardized hDSC towards the receptor tissues of Gallus gallus domesticus in ovo...

Electrophysiological devices are connected to the body through electrodes. In some applications, such as nerve stimulation, it is needed to minimally pierce the skin and reach the underneath layers to bypass the impedance of the first layer called stratum corneum. In this study, we have designed and fabricated surface microneedle electrodes for applications such as electrical peripheral nerve stimulation. We used molybdenum for microneedle fabrication, which is a biocompatible metal; it was used for the conductive layer of the needle array...

BACKGROUND: Myelin-associated glycoprotein (MAG) is a glycoprotein specific to Schwann cells. Schwann cells produce myelin for nerve cells in the peripheral nervous system. MAG also plays a role in the central nervous system (CNS) by maintaining myelin integrity and inhibiting axonal regeneration from cerebellar neurons. There is a well-established link between distal demyelinating neuropathy and anti-MAG antibodies in patients with monoclonal gammopathy of unknown significance. We describe a series of five patients with anti-MAG antibodies with evidence of cerebellar rather than just sensory ataxia and our experience of treatment with rituximab...

BACKGROUND: The Strain Index (SI) and the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value for Hand Activity Level (TLV for HAL) have been shown to be associated with prevalence of distal upper limb musculoskeletal disorders such as carpal tunnel syndrome (CTS). The SI and TLV for HAL disagree on more than half of task exposure classifications. Similarly, Time-Weighted-Average (TWA), Peak, and Typical exposure techniques used to quantity physical exposure from multi-task jobs have shown between-technique agreement ranging from 61% to 93%, depending upon whether the SI or TLV for HAL model was used...

OBJECTIVE: Sensation is essential for recovery after peripheral nerve injury. However, the relationship between sensory modalities and function of regenerated fibers is uncertain. We have investigated the relationships between touch threshold, tactile gnosis and mechanoreceptor and sensory fiber function after nerve regeneration. METHODS: Twenty-one median or ulnar nerve lesions were repaired by a collagen nerve conduit or direct suture. Quantitative sensory hand function and sensory conduction studies by near-nerve technique including tactile stimulation of mechanoreceptors were followed for 2 years, and results were compared to non-injured hands...

Nerve conduction block with a high intensity-focused ultrasound (HIFU) transducer has been performed in normal and diabetic animal models recently. HIFU can reversibly block the conduction of peripheral nerves without damaging the nerves while using an appropriate ultrasonic parameter. Temporary and partial block of the action potentials of nerves shows that HIFU has the potential to be a useful clinical treatment for pain relief. This work demonstrates the procedures for suppressing the action potentials of neuropathic nerves in diabetic rats in vivo using an HIFU transducer...

Damien Sène
Small fiber neuropathy, which affects the sensory A≏ and C fibers, is now a major diagnostic and therapeutic challenge. Nearly 7% of the general population have chronic neuropathic pain responsible for severe quality-of-life impairments. Awareness must therefore be raised among clinicians of the somatosensory and autonomic symptoms that can reveal small fiber neuropathy, appropriate diagnostic investigations, most common causes, and best treatment options for each patient profile. To help achieve this goal, the present review article discusses the clinical presentation of neuropathic pain and paresthesia and/or autonomic dysfunction due to involvement of nerves supplying exocrine glands and smooth muscle; normal findings from standard electrophysiological investigations; most informative diagnostic tests (epidermal nerve fiber density in a skin biopsy, laser-evoked potentials, heat- and cold-detection thresholds, electrochemical skin conductance); main causes, which consist chiefly of metabolic diseases (diabetes mellitus, glucose intolerance), dysimmunity syndromes (Sjögren's syndrome, sarcoidosis, monoclonal gammopathy), and genetic abnormalities (familial amyloidosis due to a transthyretin mutation, Fabry disease, sodium channel diseases); and the available symptomatic and etiological treatments...

In view of the pathologic basis for the treatment of diabetic neuropathy, it is important to enhance nerve regeneration as well as prevent nerve degeneration. So, in the present study, we have investigated the effect of S-Methylisothiourea Sulfate (selective iNOS inhibitor) and Citicoline, alone and in combination, on Type II Diabetes Mellitus induced neuropathic pain in wistar rats. Type II diabetes was induced by providing high fat diet and low dose of Streptozotocin for 35 days in rats. Type II Diabetes Mellitus was assessed in terms of increased glucose, triglycerides, cholesterol, LDL levels, glucose tolerance and decrease in HDL levels...

BACKGROUND: Carpal tunnel syndrome (CTS) is the most common peripheral neuropathy, characterized by the presence of many sensory and motor abnormalities. In the physiotherapy of patients with CTS, neurodynamic tech-niques are very common, while the scientific literature does not show clear evidence of beneficial effects obtained by using these techniques. Therefore, the aim of this work was to critically evaluate the use of neurodynamic techniques in the conservative treatment of CTS...

The contribution of resident endoneurial tissue macrophages versus recruited monocyte derived macrophages to demyelination and disease during Experimental Autoimmune Neuritis (EAN) was investigated using passive transfer of peripheral nerve myelin (PNM) specific serum antibodies or adoptive co-transfer of PNM specific T and B cells from EAN donors to leukopenic and normal hosts. Passive transfer of PNM specific serum antibodies or adoptive co-transfer of myelin specific T and B cells into leukopenic recipients resulted in a moderate reduction in nerve conduction block or in the disease severity compared to the normal recipients...

Douglas S Ruhl, Bradley W Kesser
Patients with microtia and congenital aural atresia should have a comprehensive hearing assessment early in life. Options for hearing habilitation should be presented, and children with bilateral aural atresia should be fitted with a bone conducting hearing device to support normal speech and language development. If atresia surgery is pursued, the microtia surgeon must be aware of certain principles. This article presents recommendations on options for potentially improving hearing in children with congenital aural atresia: assessing surgical candidacy; chronology and timing of surgeries; functional importance of certain ear structures; and understanding the possible locations of an aberrant facial nerve to avoid injury in these patients...
