To the Editor Reply: We wish to thank Granata et al for their letter commenting on our article on hypertrophy of peripheral nerves in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) that was detected by ultrasonography. We demonstrated a useful case which exemplifies the detection of segmental lesions of the peripheral nerves in CIDP by ultrasonography. We think that ultrasonog...

Nerve-sparing surgery is increasingly being applied to avoid functional deficits of the limbs and organs following surgery. Peripheral nerves that should be preserved are, however, sometimes misidentified due to similarity of shape and color to non-nerve tissues. To avoid misidentification of peripheral nerves, development of an in situ nerve detection method is desired. In this study, we repor...

This article reviews the epidemiology and classification of traumatic peripheral nerve injuries, the effects of these injuries on nerve and muscle, and how electrodiagnosis is used to help classify the injury. Mechanisms of recovery are also reviewed. Motor and sensory nerve conduction studies, needle electromyography, and other electrophysiological methods are particularly useful for localizin...

Objective: Diabetic patients suffer from different types of complications associated with peripheral nerves. A clear manifestation of these complications is found in the mouth where neuropathies commonly occur. The measurement of electrical stimulation threshold of teeth signifies premature involvement of peripheral nerves in the teeth. The aim of present study is to compare pulp tester respons...

The distribution and density of nerves containing vasoactive intestinal polypeptide, substance P, and neuropeptide Y around the cerebral and peripheral blood vessels of stroke-prone spontaneously hypertensive rats (SHRSP) and normotensive Wistar-Kyoto rats (WKY) were studied using an indirect immunofluorescence technique. Neonatal sympathectomy of SHRSP with anti-nerve growth factor and guaneth...

Purpose: To investigate the impact of shoulder subluxation (SS) on peripheral nerve conduction and function hemiplegic upper extremity (HUE) in poststroke patients.Methods: Thirty post-stroke patients were selected (SS group: 15 patients, non-SS respectively). Evaluation limbs: compound muscle action potential (CMAP) amplitude latency suprascapular, axillary, musculocutaneous, radial, median, u...

Introduction: The present study aims to evaluate the Three-Dimensional Diffusion-Weighted reversed fast imaging with steady state free precession (3D DW-PSIF) sequence with respect to imaging of the peripheral nerves; the tibial, medial, and lateral plantar nerves in the lower extremity, ulnar and median nerve in the upper extremity, sciatic nerve, brachial plexus, and lumbosacral plexus, and a...

Peripheral nerves are organ-like structures containing diverse cell types to optimize function. This interactive assembly includes mostly axon-associated Schwann cells, but also endothelial cells of supporting blood vessels, immune system-associated barrier-forming the perineurium surrounding and protecting nerve fascicles, connective tissue-resident within intra-fascicular endoneurium inter-fa...

1. The Wallerian degeneration occurring in peripheral nerves by incubation in Ringer solution and serum does not occur in plasma. 2. Peripheral nerves incubated in plasma give rise to no growth. The same is true of peripheral nerves in a Wallerian degeneration up to the 4th day. 3. Peripheral nerves in Wallerian degeneration from the 5th day give rise to a growth of the syncytium of Schwann. In...
