Psychometric functions for efficient and effective psychophysical testing of sensory function.

An efficient test for sensory function has been reported using random order pairs of real and sham stimuli. The constant magnitude of the real stimulus is chosen such that the first error in a patient's forced-choice report on the order of real and sham stimulation, immediately indicates abnormal sensory function. This magnitude just exceeds a critical large percentile of the psychometric function (i.

Neurological bypass for sensory innervation of the penis in patients with spina bifida.

We hypothesized that restored sensation in the penis would greatly contribute to their quality of life and sexual health.

The ileo neo rectal anastomosis (INRA) in patients with familial adenomatous polyposis: clinical results at two years.

Background: Ileo neo rectal anastomosis (INRA) is a promising alternative for patients with familial adenomatous polyposis (FAP) to restorative proctocolectomy with its morbidity and unpredictable functional outcome to colectomy with ileo rectal anastomosis (IRA) with the continuing risk of rectal cancer. The aims of the present study were to evaluate the function of the neorectum, to assess the morbidity and complications of the operation and to determine the incidence of neorectal polyps.

Methods: Data of all patients having INRA, including bowel function and complications, were prospectively recorded.
