Management of chemotherapy-induced peripheral neuropathy.

Recent advances in the development and administration of chemotherapy for malignant diseases have been rewarded with prolonged survival rates. The cost of progress has come at a price and the nervous system is frequently the target of chemotherapy-induced neurotoxicity. Unlike more immediate toxicities that effect the gastrointestinal tract and bone marrow, chemotherapy-induced neurotoxicity is frequently delayed in onset and may progress over time.

Effect of fenoldopam on ischemia/reperfusion-induced apoptosis.

Recently we demonstrated the effect of fenoldopam on ischemia/reperfusion (I/R) induced NFkappaB mediated pro-inflammatory signal transduction. However, the effect of fenoldopam on I/R-induced apoptosis is not known. We utilized a rat model of acute ischemic nephropathy to test the hypothesis that fenoldopam attenuates I/R-induced apoptosis.

Spinal glial glutamate transporters downregulate in rats with taxol-induced hyperalgesia.

Changes in the expression of glial glutamate transporters (GLAST and GLT-1) were examined in the spinal cord of rats with chemotherapy (taxol)-induced mechanical hyperalgesia. Immunohistochemical studies show that the expression of both GLAST and GLT-1 in the L4-L5 spinal dorsal horn is decreased by 24% (P<0.001) and 23% (P<0.

Taxol-induced sensory disturbance is characterized by preferential impairment of myelinated fiber function in cancer patients.

Taxol produces neuropathic pain with three distinct zones of involvement in the extremities. Most distally is an area of on-going pain and proximal to this is a zone of sensory disturbance but not overt pain. These two areas were confined in all but one case to the glabrous skin of the hands and/or feet.

Spinal cord stimulation relieves chemotherapy-induced pain: a clinical case report.

We present two patients with chemotherapy-induced painful neuropathy that had been poorly controlled with medications but successfully treated with spinal cord stimulation (SCS). A trial period of SCS provided effective pain relief in both patients who subsequently underwent permanent stimulator implantation. Psychophysical tests were performed before and after the implantation of trial and permanent stimulators.
