Randomized Controlled Trial Comparative Study Clinical Trial
Subcutaneous-PCA: an alternative to IV-PCA for postoperative pain management.
Patients (n = 120) undergoing major orthopedic (e.g., total hip replacement), urologic (e.g., radical prostatectomy), or gynecologic (e.g., total abdominal hysterectomy) procedures were randomly assigned to receive either morphine or oxymorphone postoperatively using a patient-controlled analgesic (PCA) delivery system. The opioid analgesic was administered either intravenously (IV-PCA) or subcutaneously (SQ-PCA) during the 72-h study period. ⋯ Postoperative analgesia scores and patient satisfaction were similar in all four PCA treatment groups. Thus, SQ-PCA with either oxymorphone or morphine represents a clinically acceptable alternative to IV-PCA in the treatment of postoperative pain.

Forty-six pain clinic patients (British) were compared with 143 nonclinical subjects (Canadian) on a variety of demographic and illness variables. A subset of 43 nonclinical subjects was further compared with the 46 pain clinic patients for depression and illness behaviour. Both groups were well matched for age, sex, and marital status. ⋯ Nearly 75% of subjects in both groups were aware of the diagnosis for their pain condition. On Beck Depression Inventory both groups scored in the nondepressed range. On the Illness Behaviour Questionnaire the pain clinic group scored significantly higher on disease conviction, somatization, and denial than did the nonclinical sample.

A review of Social Security Disability Income (SSDI), listed impairments (Section 1.05) for axial pain, the application process, appeals process, and the importance and impact of the treating physician's role in Social Security disability determination is discussed. The authors summarize the major types of disability programs and the present impairment rating systems, and present recent research in the complicated area of chronic pain and illness behavior that may alter the present system. They give recommendations that may aid the treating physician to prepare the patient's application for Social Security Disability Income.

We studied 31 patients with acute herpes zoster (AHZ) less than 28 days' duration. Clinical characteristics (pain, allodynia, course of disease) and somatosensory perception thresholds (thermal discrimination, hot pain, and vibration) of the affected dermatome and the contralateral homologous area were assessed. Touch-evoked allodynia was found in 17 (55%) and dysesthesia in a further 5 (16%). ⋯ Thermal threshold abnormalities were significantly associated with the prevalence of postherpetic neuralgia (PHN) at 3 months. The effect of nerve blockade was less favorable on allodynia than spontaneous pain. The results of possible pathophysiological mechanisms are discussed.
