Chronic pain is one of the most common and challenging medical problems facing our society. The specialty of pain medicine has grown steadily in recent years, largely because of the recognition that multiple factors contribute to chronic pain. ⋯ Research in the last 30 years has developed a variety of alternatives or adjuncts to opiates for chronic pain, including neuroactive medications, counterstimulation methods, and cognitive-behavioral therapies. Pain medicine specialists have provided leadership in the development of the practice, with the application of a wide verity of central and peripheral nerve blocks, sympathetic and neurolytic blocks, intradiscal procedures, neuromodulation techniques, intrathecal infusion systems, and other technical procedures that are firmly linked to a biomedical model of pain.

This review discusses a variety of causes of stupor and coma and associated electroencephalographic (EEG) findings. These include metabolic disturbances such as hepatic or renal dysfunction, which are often characterized by slowing of background rhythms and triphasic waves. Hypoxia and drug intoxications can produce a number of abnormal EEG patterns such as burst suppression, alpha coma, and spindle coma. ⋯ This entity, nonconvulsive status epilepticus (NCSE), is difficult to diagnose in obtunded/comatose patients, and an EEG is required to verify the diagnosis and to monitor treatment. Several EEG patterns and their interpretation in suspected cases of NCSE such as periodic lateralized epileptiform discharges (PLEDs), bilateral independent periodic lateralized epileptiform discharges (BIPLEDs), generalized periodic epileptiform discharges (GPEDs), and triphasic waves are reviewed. Other entities discussed include the locked-in syndrome, neocortical death, persistent vegetative state, brainstem death, and brain death.

Reviews of the use of intravenous tissue type plasminogen activator (IV tPA) for acute stroke in community hospitals have raised questions regarding its safe use in community practice settings outside major academic stroke centers. Many neurologists have been reluctant to use IV tPA in their practices. We therefore analyzed the experience of this community neurology practice in treating acute strokes with IV tPA. ⋯ IV tPA for acute ischemic stroke can be given safely and effectively by physicians in an independent neurology practice in the community hospital setting.
