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)
We consider the ethical and public policy implications of late recovery from the minimally conscious state in light of an Institute of Medicine exploratory meeting convened to discuss current knowledge about disorders of consciousness as well as a recently published study demonstrating axonal regrowth in a patient two decades after traumatic injury.(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)
The pain of acute herpes zoster (HZ) may be severe, but it is usually transitory. A minority of patients, with the elderly at particular risk, go on to develop persistent, severe, often disabling pain called postherpetic neuralgia. Though the clinical features of these conditions are well known, the pathology of PHN is poorly described and the pathogenesis(More)
To assess the usefulness of CT, we reviewed 51 patients with clinically diagnosed brachial plexopathy who were seen between 1977 and 1981. The established etiology was metastatic tumor in 46 and radiation fibrosis in 5. CT was abnormal in 89% of tumor patients. Myelography, bone scan, and plain cervical spine radiographs were less useful. In four of five(More)
The authors surveyed 1,137 physicians, nurses, and social workers (overall response = 48%) to characterize the willingness to endorse assisted suicide. Willingness to endorse varied among disciplines and was negatively correlated with level of religious belief (r = -0.35, P < 0.0001), knowledge of symptom management (r = -0.21, P < 0.0001), and time(More)
The injection of dilute formalin results in a stereotyped nociceptive behavioral response. Administration of dextromethorphan (s.c.) but not saline, 30 min prior to intraplantar formalin injection prevents this nociceptive response in a dose-dependent manner. In addition, intraplantar formalin reliably induces c-fos mRNA in the ipsilateral spinal dorsal(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)
In recent years, the observation that the response of patients to opioid drugs may be influenced by properties inherent in the pain or pain syndrome, such as its pathophysiology, has evolved into the belief that certain types of pain, e.g., neuropathic pains, may be unresponsive to these drugs. This concept has important implications for both clinical(More)
The analgesic meperidine has been reported to produce signs of central nervous system excitation in human beings. To determine the relationship between signs and symptoms of central nervous system excitation and plasma levels of meperidine and normeperidine, we studied 67 patients receiving meperidine for the relief of postoperative or chronic pain. In 48(More)
