  • small fiber neuropathies
  • Thus, pure small fiber neuropathies may be associated with normal findings on routine electrophysiologic studies. (medscape.com)
  • Gibbons et al (2009, 2010) reported that quantification of sweat gland nerve fiber density "provides a reliable structural measure of sweat gland innervation that complements the investigation of small fiber neuropathies," and that "results correlate well with physical exam findings.

  • sweat
  • Using a stereologic approach, the density of nerve fibers innervating sweat gland (SG) fragments in patients with diabetes mellitus (DM) and healthy controls using protein gene product (PGP), tyrosine hydroxylase (TH), and vasoactive intestinal peptide (VIP) was measured to determine which marker best detected differences between the groups.

  • A 50 μm thick section of a 3 mm dia. punch skin biopsy from the thigh, greater than 4 mm deep, immunohistochemically stained for the axonal protein, PGP9.5 (black fibers), to detect and quantify sweat gland innervation (blue arrow) and intraepidermal nerve fibers (red arrow). (therapath.com)
  • Sweat gland nerve fibers, also called sudomotor fibers, are small unmyelinated nerve fibers that are distinguished from somatic epidermal nerve fibers that convey pain and temperature from the skin. (therapath.com)
  • They found that sweat gland innervation was reduced in patients with autonomic neuropathy, but normal in those with MSA. (therapath.com)
  • stimulation
  • Circumstances that can trigger autonomic dysreflexia are often related to stimulation of the bladder, bowel, and skin of the patient. (thefreedictionary.com)
  • 10. It is further suggested that if the tentative assumption is made that l-nor-epinephrine is S c and l-epinephrine is S r , a simple working hypothesis is afforded for explaining both local and remote "adrenergic" effects induced by the stimulation of postganglionic sympathetic fibers and renders unnecessary the postulation of the intervention of cellular constituents in order to account for two "sympathins.
