Randomized Controlled Trial Comparative Study Clinical Trial
Randomized double-blind comparison of serotonergic (Citalopram) versus noradrenergic (Reboxetine) reuptake inhibitors in outpatients with somatoform, DSM-IV-TR pain disorder.
Whether the effect of tricyclic antidepressants on Pain Disorder arises from their noradrenergic or serotonergic actions or both remains unclear. We compared the selective serotonin reuptake inhibitor (SSRI) citalopram and the noradrenergic reuptake inhibitor (NARI) reboxetine in outpatients with Pain Disorder. We also distinguished the drugs' analgesic and antidepressant effects. ⋯ Our study suggests that the SSRI citalopram may have a moderate analgesic effect in patients with Pain Disorder, and that this analgesic activity appears to be not correlated to changes in depressive scores. If confirmed in a larger sample, this evidence suggests that patients who are intolerant or resistant to tricyclic antidepressants, may be treated with SSRIs.

Very few studies have been conducted on the presence and control of pain in Italian hospitals. ⋯ Pain affects an impressively high percentage of inpatients and is largely untreated and unrecognised in Italian wards. Educational intervention is required to improve the knowledge and attitudes of health professionals towards the approach and handling of patients in pain.

The objectives of this study were to investigate pain cognitions and quality of life of chronic pain patients referred to a multi-disciplinary university pain management clinic and to search for predictors of quality of life. ⋯ Patients from a multi-disciplinary university pain clinic experience strikingly low quality of life, whereby low back pain patients and patients with multiple pain localisations have the lowest quality of life. Pain catastrophising showed the strongest association with quality of life, and stronger than pain intensity.

Pressure pain thresholds (PPTs) in distal limbs have been under-investigated despite their potential clinical importance. Therefore, we compared PPTs over nail bed, bony prominences, and muscle in distal parts of upper and lower limbs. We investigated 12 healthy subjects using three handheld devices: a spring-loaded, analogue pressure threshold meter (PTM) with two operating ranges, and an electronic Algometer. ⋯ PPTs over distal muscles were comparable to published values on proximal limb and trunk muscles. These findings suggest that pressure pain testing over distal muscles may be a sensitive test for deep pain sensitivity and that the simple and less expensive devices are sufficient for testing this tissue type. Intra-individual site-to-site comparisons will be more sensitive than absolute normative values.

Evidence of cognitive bias in depression and anxiety has sparked an increasing interest in the potential for pain-related bias in patients suffering from chronic pain and/or illness. Research to date has been somewhat inconsistent, and the vast majority has been conducted on just two patient populations: rheumatoid arthritis (RA) and chronic pain patients. The present study investigates cognitive bias in Systemic Lupus Erythematosus (SLE) patients, particularly in relation to disease activity and depression. ⋯ Groups did not differ in their recall patterns, although all groups demonstrated a recall bias for positive words and illness words. Post-hoc analyses revealed a significant recall bias for disability-related illness words compared to sensory pain words in ill, depressed patients compared to ill, non-depressed patients and healthy controls. Consistent with the most recent research, it appears to be both the nature of the illness stimuli and the depression status of the patient that determines cognitive bias in chronically ill populations.
