Cryptogenic Sensory Polyneuropathy

Sural and Radial Sensory Responses in Patients with Sensory Polyneuropathy.

INTRODUCTION The sural/radial nerve amplitude ratio (SRAR) is the quotient of the sensory nerve action potential (SNAP) amplitudes (Amp) of the sural and the superficial radial nerve. It has been hypothesized that this ratio can be used for the detection of early axonal loss, because the sural SNAP amplitude will decrease first, thereby also decreasing the SRAR value. OBJECTIVES To determine ...

Sensory evoked potentials in Guillain-Barré polyneuropathy.

In 11 patients with acute Guillain-Barré polyneuropathy examined within 2 weeks of the onset of the paralysis, sensory evoked potential techniques were able to demonstrate a proximal conduction delay between Erb's point and the cervical cord in 10 subjects; while sensory conduction distal to Erb's point was much more commonly normal in the early period. Sensory evoked potential techniques provi...

Porokeratotic eccrine ostial and dermal duct nevus with sensory polyneuropathy and hyperthyroidism: Report of a case

The case, who discribed here is a 66-year-old man with one year history of asymptomatic, keratotic papules with a linear distribution on the skin of his right palm near the wrist. On histopathological examination cornoid lamella-like parakeratotic columns above eccrine sweat ducts were observed. The acrosyringium was also dilated. He had been followed up for predominantly sensory polyneur...

Sensory Ganglion Cell Culture for the Study of Diabetic Polyneuropathy

The commonest form of diabetic neuropathy is a distal symmetric sensory polyneuropathy. Its pathological basis has been disputed. One view has been that it is the result of multifocal hypoxic lesions in nerve that summate to produce symmetric distal axonal loss, although there are substantial indications that this is only a partial explanation. The autopsied cases reported by Sugimura and Dyck,...
