Pain management is an integral component of comprehensive cancer care. The combined goals of optimal comfort and optimal function require a working understanding of how pain therapy interacts with cancer and cancer therapy. The two main aspects of cancer which affect pain management are the cancer's treatability and its non-pain pathophysiology. ⋯ Pain therapy can impair cancer therapy by augmenting or complicating cancer therapy's adverse effects. Pain therapy can enhance cancer therapy by improving organ function and patient performance status permitting previously limited or contraindicated cancer therapies to be given. Five case studies are presented to illustrate how effective integration of pain management into comprehensive cancer care is mandatory for optimal care of cancer patients and their families.

We treat cancer pain patients at their homes, in collaboration with their relatives and primary physician. Assistance is free. ⋯ In 118 patients treated with our model between October 1987 and December 1988, we assessed the symptoms that moved them to seek assistance, their previous therapies, and the effectiveness of our intervention. The data obtained suggest that (a) in our country, the majority of cancer patients do not obtain effective pain and symptom control; (b) our model yields satisfactory pain control and improvement in quality of life; and (c) there is a need for centers that teach and practice terminal care; our model may be useful as a working outline for such centers.

In order to provide a data bank to allow a more precise and effective implementation of spinal cord stimulation, a computerized analysis of 1,375 combinations obtained from electrode arrays located in the thoracic and cervical epidural area was performed. 67 electrode arrays implanted in 34 subjects were subjected to analysis. During the stimulation trial, all the available combinations were systematically tested and the results entered into a computerized database. ⋯ Analysis of the data allow the surgeon (1) to define the characteristics of the stimulation-induced paresthesiae; (2) to define the spectrum of the electrical parameters used to stimulate the spinal cord; (3) to define the population of implanted electrode arrays/contacts; (4) to study objectively how the position of the electrodes within the spinal canal, their vertebral level and the interelectrode distance affect the electrical parameters and the stimulation-induced responses. The multifactorial systematic analysis of such a large number of combinations provides the basis for further developments in the area of electrical stimulation of the nervous system.

Randomized Controlled Trial Clinical Trial[The effect of alfentanil on pain caused by the injection of propofol during anesthesia induction in children].
Three modes of administration of alfentanil were assessed in order to reduce pain on injection with propofol. Forty healthy children scheduled for ENT surgery were included in this double-blind randomized study. All patients received intrarectal premedication with midazolam and atropine. ⋯ The children experience pain when alfentanil was administered a few seconds before or just after propofol. An bolus injection reduced significantly discomfort in patients. Dosages of alfentanil in plasma might determine the right moment of propofol injection to obtain analgesia.

Although published treatment outcome studies for chronic pain have provided favorable support for the efficacy of many pain clinics and the use of specific modalities such as biofeedback and relaxation, there are several factors that mitigate against euphoria. Two related factors that influence interpretation of these reported outcomes are discussed, namely, noncompliance with therapeutic recommendations during treatment and subsequent to treatment termination, and relapse. Conceptual and methodological problems for establishing the prevalence of noncompliance and relapse are reviewed. ⋯ Studies on arthritis and heterogeneous pain clinic populations suggest that noncompliance and relapse are related; however, this association is less well established for headache patients. Strategies for assessing compliance (i.e., self-report, behavioral, biochemical, and clinical outcome) and the perspectives' of patients and health-care providers on the application of self-care recommendations are discussed. Strategic planning and adherence enhancement tactics to facilitate maintenance of post-treatment gains are described.
