Multiple system atrophy presenting with acute respiratory failure due to diaphragmatic dysfunction.

Sleep related respiratory dysfunction and vocal cord paralysis are considered to be the major factors responsible for respiratory failure in multiple system atrophy (MSA). We report a patient initially presenting with alveolar hypoventilation culminating in respiratory failure, ultimately diagnosed as MSA. No central sleep apnea or marked paralysis of the vocal cords was noted. The most likely cause for the respiratory failure was thought to be the weakness of respiratory musculature. This case emphasizes the need that MSA should be added to the differential diagnosis of unexplained hypercapnic respiratory failure.

A case report of an uncommon neuropathy: posterior femoral cutaneous neuropathy.

Isolated posterior femoral cutaneous neuropathy is rarely encountered. Electrophysiological documentation has only been made in a few cases. We present a 73 year-old male patient who underwent a coronary angiography procedure which was performed on his right femoral artery 2 months prior of referring to our electromyography (EMG) laboratory. After this event, he had an operation in order to evacuate the hematoma formed in the right inguinal region during the procedure. In the postoperative state he began to complain of a pain and numbness in his right posterior thigh; which had radiated towards his right hip and popliteal fossa. In addition to routine electrophysiological nerve conduction studies conducted in lower extremities; we performed posteriorfemoral cutaneous nerve conduction using the method described by Dumitru and Nelson. While normal response can be obtained easily on the left side; no potential could be obtained from the right.

Sensitivity of median sensory nerve conduction tests in digital branches for the diagnosis of carpal tunnel syndrome.

OBJECTIVE: To compare the sensitivity of median sensory nerve conduction tests performed by stimulating digital branches in patients with carpal tunnel syndrome. DESIGN: A prospective study in 506 hands of patients with carpal tunnel syndrome diagnosed electrophysiologically. RESULTS: The sensitivity of median sensory nerve conduction tests across the first three digit-to-wrist segments and palm-to-wrist segment was determined. The most common abnormal electrophysiologic finding was the slowing of sensory nerve conduction velocity over the palm-to-wrist segment, which was detected in 98.5% of the hands. Slowing of sensory nerve conduction velocity over the digit 1-, 2-, and 3-to-wrist segments of the median nerve was found in 95.4%, 88%, and 82% of the hands, respectively. CONCLUSION: The sensory nerve conduction velocity test of the digit 1-to-wrist segment has the most sensitivity among the three digital branches of the median sensory nerve, and it may be used more widely in the electrodiagnosis of carpal tunnel syndrome.
