Active clinical trials for "Hyperhidrosis"

T3/T4 endoscopic thoracic sympathicotomy is a widely accepted and effective treatment for primary palmar hyperhidrosis. However, sympathetic ganglions are invisible with traditional thoracoscopy and until now, the location of ganglions are confirmed by rib indirectly. The team from thoracic department of Peking University People's Hospital discovered that the sympathetic ganglions can be visualized with fluorescent thoracoscopy. Thus, investigators want to apply fluorescent thoracoscopy in sympathicotomy of palmar hyperhidrosis, to conduct a more precise operation and compare the efficiency of the novel and traditional methods.

This study aims to assess the longus colli muscle thickness by ultrasonography in order to guide stellate ganglion blocks

Evaluate the long term efficacy and side effects of oxybutynin in the treatment of hyperhidrosis.

To evaluate the gravimetric sweat measurements in subjects who meet the subjective criteria for a diagnosis of palmar hyperhidrosis compared to subjects without hyperhidrosis.
