Clinical Trial Controlled Clinical Trial
Development and preliminary validation of a postoperative pain measure for parents.
Parents are now primarily responsible for the at home assessment and treatment of their children's pain following minor surgery. Although some research has suggested that parents underestimate their children's pain following surgery, no behavioral measure exists to assist parents in pain assessment. The Postoperative Pain Measure for Parents was developed based on cues parents reported using to assess their children's pain (e.g. changes in appetite, activity level). ⋯ This study provides preliminary evidence for the use of the Postoperative Pain Measure for Parents as a valid assessment tool with children between the ages of 7-12 years following day surgery. It is internally consistent and strongly related to child-rated pain. Future research should explore the use of this measure with a younger sample and children with developmental delays.

The problem of pain following spinal cord injury challenges the health care community to develop new treatment strategies for patients requiring pain management. A number of pain syndromes are associated with spinal injury based on the nature of the lesion, neurological structures damaged, and secondary pathophysiological changes. Efforts to identify specific characteristics of each syndrome are an important beginning to the successful diagnosis and treatment of spinal injury pain. ⋯ Future research related to these hypotheses will need to focus on the use of appropriate injury models that simulate the pathological changes associated with human injuries and which lead to clinically relevant pain-related behaviors. Continued research directed towards an examination of these proposed mechanisms will also require new research strategies and a cooperative working relationship between basic and clinical scientists. In this review the clinical characteristics of spinal injury pain and the results of experimental studies are discussed.

Patients with chronic non-malignant pain are often suspected of reporting medical symptoms that have non-organic as opposed to purely organic origins. According to the somatization hypothesis, non-organic reporting occurs when affective or other benign physical sensations are misconstrued as symptoms of physical disease [corrected]. Psychological tests purporting to assess somatization are limited by their self-report format and may be confounded in patients with physical disease or injury. ⋯ When compared to Minimizers, Amplifiers were disabled for a significantly greater number of days, reported significantly more impairment in domestic functioning, were significantly less active, visited the doctor significantly more often, and were significantly more distressed. The results suggest that substantial differences in disability and medical visitation may exist among patients who may not differ appreciably in their level of organic pathology. Instead, differences in illness behavior may, to some extent, be mediated by differences in somatization.

Randomized Controlled Trial Clinical Trial
Nimodipine fails to enhance the analgesic effect of slow release morphine in the early phases of cancer pain treatment.
We assessed nimodipine's ability to increase the analgesic effect of morphine in 32 patients suffering from cancer pain in a double-blind, placebo controlled cross-over study. Morphine administration began a few days before the start of the study. The analgesic effects of two combinations were compared: morphine (M) plus placebo (P) and morphine plus 90 mg/24 h of nimodipine (N). ⋯ However, when the same statistical tests were used for comparison of results with pre-treatment baseline values, highly significant differences between mean scores on the scales for pain relief and pain intensity were found. Based on these negative results we conclude that nimodipine given orally at a dose of 30 mg every 8 h does not enhance analgesia when associated with morphine in the early phases of treatment for cancer pain. Our study also gives clear evidence of a placebo effect.

Effect of present pain and mood on the memory of past postoperative pain in women treated surgically for breast cancer.
In our recent retrospective study on breast cancer patients, the intensity of the past postoperative pain was a primary factor in predisposing the development of chronic post-treatment pain. The present prospective study was designed to find out if the remembered intensity of postoperative pain (RIPP) after breast surgery was influenced by the development of chronic pain and if the RIPP had any correlation with the development of depression or anxiety. The patient's estimation of the severity of the RIPP was determined three times in the year after surgery. ⋯ Their depression remained at a higher level during the first year after surgery. The results suggest that the amount of postoperative pain may play a role in the development of chronic pain. However, the development of chronic pain is connected to a tendency to overestimate previous pain and to higher levels of depression.
