Correlations between coping styles and symptom expectation for whiplash injury.
In pain conditions, active coping has been found to be associated with less severe depression, increased activity level, and less functional impairment. Studies indicate that Canadians have a high expectation for chronic pain following whiplash injury. Expectation of recovery has been shown to predict recovery in whiplash victims. ⋯ The correlation between passive coping style score and expectation score was 0.62, while the correlation between active coping style score and expectation was -0.48. Both expectations and coping styles may interact or be co-modifiers in the outcomes of whiplash injury in whiplash victims. Further studies of coping style as an etiologic factor in the chronic whiplash syndrome are needed.

Prevalence of anxiety and depression in osteoarthritis: use of the Hospital Anxiety and Depression Scale as a screening tool.
The aims of this study are to ascertain the prevalence of anxiety and depressive disorders in an outpatient population with osteoarthritis (OA), examine the interrelationships between severity of OA, pain, disability, and depression, and evaluate the Hospital Anxiety and Depression Scale (HADS) as a screening tool for this population. Patients with lower limb OA were evaluated with the Short Form McGill Pain and Present Pain Index Questionnaires, and a visual analogue scale, WOMAC Osteoarthritis Index-section C, and the HADS. Participants underwent a structured clinical interview by a liaison psychiatrist (AB). ⋯ HADS is a valid and reliable screening instrument for detecting mood disorder, but not a diagnostic tool or a substitute for asking about symptoms of depression. The interrelationship between mental health, pain and disability is strong. We should therefore adopt a multidisciplinary approach to the management of OA.

The synovial fluid adiponectin-leptin ratio predicts pain with knee osteoarthritis.
The relationship between adipokines, such as leptin and adiponectin, and cartilage degeneration is being increasingly recognized. We asked what the relationship is between these hormones and patient-reported knee osteoarthritis (OA) pain. We collected demographic data, Short Form McGill Pain scores, Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain scores, and synovial fluid (SF) samples from 60 consecutive patients with severe knee OA at the time of joint replacement surgery. ⋯ The correlations between the individual adipokines and the pain scales were low to moderate and consistently less than that for the corresponding adiponectin/leptin (A/L) ratio. Linear regression modeling showed that the A/L ratio was a significant predictor of a greater level of pain on the MPQ-SF (p=0.03) but not the WOMAC pain scale (p=0.77). A greater A/L ratio was associated with less pain with severe knee OA and this metabolic pathway may represent a target for novel therapeutics.
