Comparative StudyTreatment of pain and other symptoms in cancer patients: patterns in a North American and a South American hospital.
The charts of 200 consecutive patients with cancer pain admitted to a major teaching hospital in Edmonton, Canada (n = 100) and in Buenos Aires, Argentina (n = 100) were reviewed to assess the differences between North American (NA) and South American (SA) facilities in patterns of treatment of pain and other symptoms. Criteria for eligibility and methods were identical in both hospitals. Characteristics of patients (age, sex, primary tumor, reason for admission) and attending staff were similar between both hospitals. ⋯ The types of narcotics and the use of adjuvant drugs were significantly different between NA and SA. Nonpharmacologic treatments, antiemetics, and laxatives were more frequently used in NA. These results suggest that there are significant differences in symptomatic management of advanced cancer between institutions in NA and SA.

Similarities in pain descriptions of four different ethnic-culture groups.
The purpose of this study was to identify pain terms commonly used by Hispanics, American Indians, blacks, and whites to describe painlike experiences. Subjects were asked to rate the intensity of the terms pain, ache, and hurt on a Visual Analogue Scale. Following this procedure, they were given three separate copies of the McGill Pain Questionnaire and asked to choose the words that represented pain, ache, and hurt, respectively. ⋯ There was a significant difference between the intensity level of the three terms (p less than 0.001). Word descriptors that distinguished pain from ache and hurt are presented. The importance of these findings for clinical practice is discussed.

Comparative StudySubarachnoid and epidural calcitonin in patients with pain due to metastatic cancer.
Nine patients with metastatic cancer who had pain refractory to traditional treatments received a subarachnoid injection of salmon calcitonin. Eight of the nine patients reported pain relief after subarachnoid injection varying from 1 hr to 5 days. Four of the responding patients subsequently received an epidural injection of salmon calcitonin, and two of these patients reported pain relief. Although many patients experienced pain relief, nausea and vomiting appeared to be a significant side effect, occurring in seven out of nine patients.

This review draws on data obtained in the cancer pain, nonmalignant pain, and addict populations to examine critically the major issues raised by the use of chronic opioid therapy in nonmalignant pain. The available evidence suggests that there is probably a selected subpopulation of patients with chronic nonmalignant pain who may obtain sustained partial analgesia without the development of toxicity or the psychologic and behavioral characteristics of addiction. Future discussions of this approach must adequately define the terminology of addiction and strive to distinguish medical considerations from the societal and regulatory influences that may affect prescribing behavior. Those who treat patients with chronic pain must actively participate in these discussions lest decisions with enormous impact on patient care be made solely by those whose primary responsibility is the elimination of substance abuse.

The treatment of severe pain requires the use of potent opioid analgesic medications. Many patients with opioid sensitive pain are being undermedicated. This results in increased morbidity and needless suffering. ⋯ Dependence and tolerance are virtually inevitable outcomes of long-term opioid use, but they are neither sufficient to cause addiction nor the equivalent of it. Indeed, the evidence shows that only a tiny fraction of patients treated with opioids become addicted. There is little risk of addiction for those patients receiving properly administered opioids for pain.
