OBJECTIVE : Pain catastrophizing is an important predictor of functioning and disability among individuals with chronic pain, and modification of catastrophic interpretations of pain is a proposed treatment mechanism of pain rehabilitation. The purpose of the current study is to examine the relationship between changes in catastrophic thinking and treatment outcomes for a large sample of patients with chronic pain. METHODS : 648 adult patients with chronic pain completed a 3-week intensive outpatient comprehensive pain rehabilitation program. ⋯ RESULTS : Consistent with prior research, pain catastrophizing was associated with several negative pain-related outcomes. Results of a within-subjects mediational analysis indicated that pain catastrophizing not only improved during the treatment program, but also accounted for a significant portion of the variance in the reduction of pain severity, pain interference, and depression at the end of treatment. CONCLUSIONS : This study adds further support to the position that pain catastrophizing has a detrimental role in adaptation to chronic pain, and that this construct can be successfully modified in treatment to improve patient outcomes.

Comparative Study
Women with Chronic and Episodic Migraine Exhibit Similar Widespread Pressure Pain Sensitivity.
To investigate widespread pressure hyperalgesia in the trigemino-cervical and extra-trigeminal (distant pain-free) regions in women with episodic and chronic migraine. ⋯ This study found similar widespread pressure hypersensitivity in women with episodic or chronic migraine suggesting that central manifestations are involved both in episodic and chronic migraine.

Intraarticular Morphine Overdose: The Role of the Perioperative Physician.

Posttraumatic stress disorder (PTSD) and pain are frequently comorbid conditions that can result in bidirectional exacerbations. Initial research suggests physical activity may prevent PTSD symptoms or assist with recovery. Unfortunately, Veterans with PTSD are less likely to engage in physical activity, often citing pain as a primary reason. The current study examines the potential role of physical activity as a moderator of the pain and PTSD relationship. ⋯ For Veterans seeking treatment for PTSD, physical activity was particularly salient for those reporting high levels of pain severity and intensity. While assessment of pain is recommended with all Veterans, it may also be beneficial to evaluate physical activity in those with prominent pain complaints. Further examination of the role of exercise in integrated care for pain and PTSD is warranted.

Randomized Controlled Trial
Pregabalin Improves Pain Scores in Patients with Fibromyalgia Irrespective of Comorbid Osteoarthritis.
Fibromyalgia (FM) is a chronic pain disorder with patients frequently suffering from comorbid conditions, including osteoarthritis (OA). Data on how FM patients with comorbid OA respond to recommended therapies (such as pregabalin) could help their treatment. ⋯ FM patients with or without comorbid OA respond to treatment with pregabalin 450mg/day with significant improvements in pain intensity scores. These data could provide guidance to healthcare professionals treating these patients.
