The effect of carpal tunnel release on median nerve flattening and nerve conduction.
Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy and extensive surveys have been given on the time course of electrophysiological findings pre- and postoperatively. In patients with clinical and electrophysiological confirmed diagnosis of CTS surgical decompression of the carpal tunnel is a first line treatment and has proven to be successfull in 70 to 90% of all cases. The objective of this work was to study the morphological changes of the median nerve after endoscopic release of the carpal tunnel. ⋯ There was significant normalization of the calculated flattening ratio of the median nerve already 2 weeks after surgical release, whereas nerve conduction studies needed a longer period of time to normalize and thus were still abnormal 3 months postoperatively. We conclude that ultrasound is a simple and excellent objective method for visualizing the morphological recovery of the median nerve very early after decompression surgery. In complex cases with unsatisfactory outcome ultrasonography may prove useful in confirming successfull or failed decompression of the median nerve.

Case ReportsUlnar neuropathy at Guyon's canal: electrophysiological and surgical findings.
Published correlations between electrophysiological and surgical findings are relatively rare in cases of ulnar nerve compression at the wrist, compared to the more common compression of the ulnar nerve at the elbow. We describe a patient who presented with clinical and electrodiagnostic findings of a pure motor ulnar neuropathy involving the territory of the deep branch. Surgical exploration revealed that a ganglion cyst caused compression of the deep ulnar motor branch at Guyon's canal. This case illustrates the usefulness of electrodiagnostic studies in the localization of nerve entrapment prior to surgery.

Case ReportsUnilateral diaphragmatic paralysis following thoracic outlet surgery: a case report.
In this report, a young female, who initially presented with left upper extremity pain, eventually underwent surgery for presumed thoracic outlet syndrome. Following surgery, she developed shortness of breath. Diagnostic studies revealed an elevated left hemidiaphragm secondary to injury to the phrenic nerve.

Brachial plexopathy: a clinical and electrophysiological study.
A retrospective study to evaluate the clinical and electrophysiological profile of brachial plexus lesions in a tertiary care center of India. ⋯ Recovery in the traumatic group correlated well with the electrophysiological abnormalities while no such correlation was evident in the idiopathic group.

Comparison of sympathetic skin response between palmar hyperhidrotic and normal subjects.
Palmar hyperhidrosis is a disorder with excessive sweating. The purpose of this study is to evaluate the autonomic function in palmarhyperhidrotic patients with Sympathetic skin response (SSR) test. In this study SSr was performed for the upper limbs of 20 patients with palmar hyperhidrosis, who did not have any other systemic or localized wrist and palmar disease as "Involved Group" and 28 healthy subject as "Control Group" without any palmar hyperhidrosis, systemic or local disease. ⋯ V. < 0.001) 95%. Beside, in this study, we observed a direct correlation between severity of symptom and the degree of SSR abnormality. Therefore, involvement of sympathetic nervous system in palmar hyperhidrosis were highly suspected.
