"Idiopathic" Shoulder Pain and Dysfunction from Carpal Tunnel Syndrome and Cubital Tunnel Syndrome.

Article Synopsis
- The study focuses on patients with chronic shoulder pain, identifying mild carpal and cubital tunnel syndromes as potential underlying causes that are often overlooked.
- A treatment approach started with a night-time wrist orthosis, followed by nerve blocks, and if necessary, surgery, led to significant pain relief and improved shoulder motion for many patients.
- The results suggest that careful examination can help diagnose these conditions early, leading to better outcomes in treating shoulder pain linked to compressive neuropathy.
Background: To better understand the nature of magnetic resonance imaging (MRI) findings in schwannomas, especially in the "target sign" of these findings, the histopathological investigation was performed.
Methods: The MRI findings were correlated with histopathological features in 22 samples of schwannomas, which were mostly resected from the extremities. The histopathological analyses included alcian blue staining and immunohistochemical staining for S-100 protein, proliferating cell nuclear antigen (PCNA) and epithelial membrane antigen (EMA).
Case: A 65-year-old man with a completely transected left sciatic nerve at the buttock received an implant with a bioabsorbable nerve conduit over a 20-mm gap. The conduit was filled with collagen to facilitate nerve regeneration. At 4 years after implantation, reinnervation potentials were detected in the muscles, and there was sensory recovery in the reinnervated areas.

A combination of these two treatments (ETMS-MT) may result in greater gain than either treatment alone.
Objectives: The feasibility and possible effects of ETMS-MT upon upper extremity function were investigated in stroke patients.
Objective: To investigate the feasibility of peripheral sensory nerve stimulation combined with task-oriented training in patients with stroke during inpatient rehabilitation.
Design: A pilot randomized crossover trial.
Setting: Two rehabilitation hospitals.
In order to obtain information regarding the correlation between an electroencephalogram (EEG) and the state of a dolphin, we developed a noninvasive recording method of EEG of a bottlenose dolphin (Tursiops truncatus) and an extraction method of true-EEG (EEG) from recorded-EEG (R-EEG) based on a human EEG recording method, and then carried out frequency analysis during transportation by truck. The frequency detected in the EEG of dolphin during apparent awakening was divided conveniently into three bands (5-15, 15-25, and 25-40 Hz) based on spectrum profiles. Analyses of the relationship between power ratio and movement of the dolphin revealed that the power ratio of dolphin in a situation when it was being quiet was evenly distributed among the three bands.

This report describes the treatment of two cases of motor nerve disorder.
Methods: The bioabsorbable nerve tube was a cylindrically woven polyglycolic acid (PGA) tube filled with collagen.
Two patients with causalgia associated with allodynia and finger contracture were treated surgically with a bioresorbable nerve guide tube made from polygycolic acid and collagen: the injured segment of the digital nerve was resected and the resulting gap (25 and 36mm) was bridged with the tube. In both cases, a neuroma was found on the injured nerve and many sprouting branches were. After reconstruction, the causalgia and allodynia disappeared and movement of the fingers recovered during the following 6 months.

Our previous successes in regenerating canine peripheral nerves across long distances (80-mm gaps) using a bioabsorbable tube have led us to investigate the value of such a tube for the treatment of human patients with chronic nerve injuries.
Methods: The device was made from a cylindrically woven polyglycolic acid tube filled with a collagen sponge.
