Sensory Neuropathies

Hereditary and Sensory Autonomic Neuropathies

Dear Editor; We read with interest two recent papers on Congenital insensitivity to pain with anhidrosis, entitled " Congenital insensitivity to pain and anhydrosis (CIPA) syndrome; a report of 4 cases " by Daneshjou et al [1] and " Congenital insensitivity to pain with anhidrosis (HSAN type IV), extremely rare syndrome that can be easily missed by bone and joint surgeons: a case report " by Al...

Hereditary motor and sensory neuropathies.

The hereditary motor and sensory neuropathies (HMSN) represent a genetically heterogeneous collection of disorders in which patients develop a progressive muscular atrophy and sensory neuropathy of the distal extremities. Although Dyck' has noted seven types, the best described of these are HMSN types I and II (Charcot-Marie-Tooth disease) and Dejerine-Sottas (DS) disease, HMSN III. In contrast...

Sensory Neuropathies Chronic Sensorimotor Distal Symmetrical Polyneuropathy

Hereditary sensory and autonomic neuropathies: types II, III, and IV

The hereditary sensory and autonomic neuropathies (HSAN) encompass a number of inherited disorders that are associated with sensory dysfunction (depressed reflexes, altered pain and temperature perception) and varying degrees of autonomic dysfunction (gastroesophageal reflux, postural hypotention, excessive sweating). Subsequent to the numerical classification of four distinct forms of HSAN tha...

Comparison of sudomotor and sensory nerve testing in painful sensory neuropathies.

OBJECTIVE To compare results of quantitative sudomotor axon reflex testing (QSART), dorsal sural, and sural sensory nerve testing in patients with painful sensory neuropathy (PSN). METHODS Fifty-six patients with symptoms and neurologic examinations consistent with PSN who had both autonomic and nerve conduction studies were identified from 376 patients with a clinical diagnosis of painful ne...
