This study examined profiles of self-reported depressive symptoms in chronic pain patients (n = 51), family practice outpatients (n = 52), and controls (n = 53) who were receiving neither psychological nor medical treatment and were pain free. Subjects in the three groups were matched for age and sex. ⋯ Chronic pain and family practice groups had similar SMDI profiles, with significant elevations on Low Energy, Pessimism, Sad Mood, and Low Self-Esteem subscales compared with controls. Although both groups of medical patients were depressed compared with control subjects, their SMDI profiles were different from those previously reported for psychiatric inpatients with a diagnosis of depression.

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 patients (ASA status I-III) recovering from major orthopedic or gynecological operations were investigated to evaluate analgesic efficacy and threshold concentrations of tramadol and its main metabolite O-demethyltramadol (M1) in serum during the early postoperative period, using patient-controlled analgesia (PCA) by means of the Abbott Lifecare Infuser. Following an individualized intravenous loading dose of 97.5 +/- 42.3 mg (mean, SD), tramadol demand doses were 20 mg with a limit of 500 mg within 4 h; the lockout time was set to 5 min. The duration of PCA was 20.5 +/- 4.8 h. ⋯ Minimum effective tramadol serum concentration (MEC) varied greatly and could be best described by a log-normal distribution (range 20.2-986.3 ng/ml, median 287.7 ng/ml). Intraindividual MEC variability was lower than intersubject variability (38.2 vs 59.1%). Median M1 concentrations were 36.2 ng/ml.

The therapeutic habits of general practitioners are an important clue when drug therapy is considered, because they are treating the most frequent complaints. When pain problems are considered, it would be valuable to determine the characteristics of the pain consultations and their therapeutic attempts to solve these complaints. The present study was designed to elucidate the characteristics of pain diagnoses and treatment approaches at primary-care level in Spain. ⋯ Physicians prescribed diclofenac at full doses, but aspirin and paracetamol were used at subtherapeutic dosages. The study showed that (a) rheumatic pain was the most frequent at primary-care level, (b) a high level of self-medication was determined, therefore recommending a careful drug history, and (c) misconceptions about analgesic drugs may partially explain the therapeutic failure in some patients. Educational programs in rheumatic pain and analgesic therapy for general practitioners are strongly recommended.
