Axillary neuropathy in volleyball players: report of two cases and literature review.

Two cases of isolated neuropathy, not consequent to acute trauma, of the axillary nerve of young volleyball players are described. Interest in the pathology derives from the rarity of such case reports and the fact that the pathogenesis may be linked to a specific sporting activity. The lesion site is thought to be in the quadrilateral space.

Autonomic diabetic neuropathy: skin sympathetic response and neurovegetative cardiovascular functionality tests.

One hundred and twelve diabetic patients were submitted to several tests for evaluation of autonomic cardiovascular and sudomotor function. It was found that a patient could be positive to one test and negative to others, thus confirming the presence of sectorial lesions which do not affect the autonomic nervous system uniformly. The parasympathetic system is more frequently and precociously affected than the sympathetic system.

Sympathetic skin response in chronic renal failure and correlation with sensorimotor neuropathy.

Twenty subjects suffering from chronic renal failure and undergoing continual treatment by haemodialysis were examined, and the following values assessed: maximum conduction velocity of the sensory and motor fibres of the common peroneal nerve, the relative electromyographic parameters, and the sympathetic skin response at the level of the foot. The results obtained have shown that autonomic neuropathy involving the sympathetic sudomotor is less frequent than sensorimotor neuropathy. The autonomic failures are scanty in the mild forms of sensorimotor neuropathy, with minor latency in the onset of uremia.
