The clinical neurologist frequently encounters patients with a variety of focal sensory symptoms and signs. This article reviews the clinical features, etiologies, laboratory findings, and management of the common sensory mononeuropathies including meralgia paresthetica, cheiralgia paresthetica, notalgia paresthetica, gonyalgia paresthetica, digitalgia paresthetica, intercostal neuropathy, and mental neuropathy.

ReviewEthical issues in the management of chronic nonmalignant pain.
Chronic pain represents a challenge to patients, families, employers, and the physicians who care for these individuals. Opioids remain the mainstay of the analgesic medications for the treatment of both acute and chronic pain. Controlled release preparations of morphine, oxycodone, fentanyl and long acting opioid agents such as methadone and levorphanol have been medically and ethically accepted in managing chronic cancer pain. ⋯ Although most patients on the opioid regimen do well, special attention must be given to patients with current addiction, a past history of addiction, or current misuse of opioid medications. Pharmacologic and conservative interventions are often warranted in those patients with significant behavioral problems. If such strategies fail, and chronic opioid therapy is deemed necessary, some treatment guidelines are offered.

With the increasing acceptance of the right of patients to refuse life-sustaining treatment, some have argued that terminally ill patients have a corollary right to physician-assisted suicide (PAS) on request. However, there are important moral and legal distinctions between patients' refusals of therapy and requests for certain actions. Physicians must stop life-sustaining therapy when that therapy has been validly refused by patients. ⋯ The morality of PAS is debatable but it remains illegal in most jurisdictions. Advocates of legalizing PAS should fully understand three issues: (1) that such legalization would have a negative effect on the practice of palliative care and on the physician-patient relationship; (2) that legalization of voluntary euthanasia will follow the legalization of PAS; and (3) that involuntary euthanasia inevitably follows the legalization of voluntary euthanasia, as has occurred in the Netherlands over the past 12 years. Rather than suffer the harms resulting from legalizing PAS, our society should maintain its illegality and make an expanded effort to improve physicians' training and abilities to provide palliative care.

High-voltage electrical injuries may be devastating, with extensive burns, cardiac arrest, amputations, and long, complicated hospitalizations. Low-voltage injuries, after other pathologic and high-voltage sources are ruled out, tend to be rather benign acutely although they may have significant long-term morbidity, including chronic pain syndromes. Lightning injuries affect 800 to 1000 persons per year. ⋯ Although high-voltage injuries may require the services of trauma surgeons, in general, therapy for low-voltage and lightning injury is supportive and involves cardiac resuscitation for the more seriously injured and supportive care for the less severely injured. Long-term problems from sleep disturbances, anxiety attacks, pain syndromes, peripheral nerve damage, fear of storms (for lightning patients), and diffuse neurologic and neuropsychologic damage may occur in both electrical and lightning patients. Other sequelae--such as seizures or severe brain damage from hypoxia during cardiac arrest and spinal artery syndrome from vascular spasm--are indirect results of electrical and lightning injury.
