Abstract
introduction cold-induced sweating syndrome type 1 (CISS1), is a rare, severe, autosomal recessive disease. It is characterized by morphological alterations and profuse sweating when ambient temperature is <22 degrees C. although some individuals with CISS1 have decreased pain perception, no study has been conducted to evaluate thermal and pain sensations in these patients. the aim of this study was to assess the function of the nociceptive a-fibers and warmth C-fibers by using CO2 laser-evoked potentials (LEPs) in patients affected by CISS1. methods four patients were studied. Laser pulses were applied to the skin of the right hand and the perioral region at painful intensity to record A-LEPs, and at non-painful intensity to obtain C-LEPs. fifteen healthy subjects were studied for control purposes. results no significant difference in latencies or amplitudes of either A- or C-LEPs was found between the 2 groups .conclusion cutaneous nociceptive and warmth pathway functions are normal in CISS muscle and nerveFile | Dimensione | Formato | |
