BACKGROUND The transdermal therapeutic system (fentanyl), or TTS(fentanyl), continuously delivers fentanyl for up to 72 h. The transdermal therapeutic system (fentanyl)-100 delivers approximately 100 micrograms/h. The repeated dose pharmacokinetics of this drug using the recommended dosing interval have not been evaluated previously and were determined in(More)
A 48-year-old woman with a stimulating electrode implanted in the right thalamic nucleus ventralis posterolateralis developed compulsive self-stimulation associated with erotic sensations and changes in autonomic and neurologic function. Stimulation effects were evaluated by neuropsychologic testing, endocrine studies, positron emission tomographic(More)
In patients with cancer, brachial plexus signs are usually caused by tumor infiltration or injury from radiation therapy (RT). We analyzed 100 cases of brachial plexopathy to determine which clinical criteria helped differentiate tumor from radiation injury. Seventy-eight patients had tumor (34 with previous RT), and 22 had radiation injury. Severe pain(More)
Thirty-eight patients maintained on opioid analgesics for non-malignant pain were retrospectively evaluated to determine the indications, course, safety and efficacy of this therapy. Oxycodone was used by 12 patients, methadone by 7, and levorphanol by 5; others were treated with propoxyphene, meperidine, codeine, pentazocine, or some combination of these(More)
OBJECTIVE The American Academy of Neurology (AAN) surveyed the attitudes, behavior, and knowledge of its members regarding care at the end of life. Three groups of AAN members were surveyed: neuro-oncologists, ALS specialists, and a representative sample of US neurologists. METHODS The survey presented two clinical scenarios involving end-of-life care.(More)
Opioids cause constipation by binding to specific opioid receptors in the enteric and central nervous systems. First-pass glucuronidation limits systemic bioavailability of oral naloxone. This study was designed to determine if oral naloxone could reverse opioid-induced constipation without precipitating abstinence or recrudescence of pain in(More)
