Optimal care of surgical patients includes effective control of incisional pain. Attention is beginning to be focused on new in-hospital services created to improve the management of postoperative pain. Additional information regarding the organization and operation of this type of service, especially in the framework of a university hospital, is presented. The specific roles of an academic anesthesiologist involved in acute pain management are: to provide leadership by the development of effective services, to clarify through research optimal treatments, to train future practitioners in the management of acute pain, and to serve as a consultant for improving pain control for the whole medical community.

Review Case Reports
The assessment and treatment of pain in the emergency room.
A broad spectrum of painful conditions presents to the modern emergency center (EC). The three most common categories are acute, self-limited disorders; chronic medical or surgical syndromes with acute exacerbation; and psychic pain syndromes in which the etiology cannot be easily ascertained. Many factors may differentiate pain from suffering, and physicians should educate patients not only about the nature of their condition and its prognosis, but also about anticipated discomfort. ⋯ Two special groups of patients, those with psychic pain syndromes and those with drug-seeking behavior, can create problems for the physician. Patients with chronic pain syndromes need special follow-up but do not benefit from additional analgesic drug therapy. Patients who seek and abuse drugs can be difficult to identify, may have true underlying medical pathology, and should not be given narcotic prescriptions.

Recent research advances indicate that specialized neural pathways are involved in the encoding of pain sensations and that these pathways are sensitive to changes in stimulus features, such as intensity, quality, duration, and location. It has also been established that there are three major families of opioid peptides in the brain: the enkephalins, the dynorphins, and the endorphins. In addition to these opioid peptides, other neurochemicals such as serotonin and norepinephrine play a role in the modulation of signals related to tissue damage. ⋯ Opioid drugs are administered into the membranes surrounding the spinal cord to provide long-lasting pain relief. Peripherally acting opioid drugs may represent a new functional class of analgesics devoid of the undesirable side effects of centrally acting opioids. Tricyclic antidepressant drugs are used in the treatment of neuropathic pain, based on their effects on noradrenergic and serotoninergic pathways in the central nervous system.

Review Case Reports
Common painful sports injuries: assessment and treatment.
The increasing participation in organized sports has been paralleled by an increasing number of sports injuries. An exact diagnosis of the injury and an understanding of the mechanisms of injury are essential for proper management, relief of pain, and restoration of function. The two mechanisms of injury are single-impact macrotrauma and repetitive microtrauma. ⋯ The roles of non-narcotic analgesics, muscle relaxants, and nonsteroidal anti-inflammatory drugs (NSAIDs) in aiding recovery and restoration of function in sports injuries have been extensively studied. NSAIDs, in particular, have been demonstrated in clinical and laboratory studies to speed recovery from overuse sports injury. Their place in acute sports injuries due to single-impact macrotrauma, however, is more controversial.
