Randomized Controlled Trial
Validation of the PAC-SYM questionnaire for opioid-induced constipation in patients with chronic low back pain.
The Patient Assessment of Constipation Symptoms (PAC-SYM) questionnaire is a 12-item self-report instrument divided into abdominal, rectal and stool domains. ⋯ PAC-SYM is a reliable, valid and responsive measure of the presence and severity of opioid-induced constipation symptoms.

The development of catheter associated granulomatous masses in intrathecal morphine therapy is an uncommon, but potentially serious problem. While these systems have historically been used in patients with short life expectancies, more recently patients with pain from a benign source have benefited from this therapy, and new complications are being encountered secondary to the patients' longer life spans. Morphine is the most commonly used intrathecal opioid and evidence exists that the formation of granulomatous masses are related to the use of higher doses. ⋯ Serial neurological examinations for new deficits may be performed and recorded during pump refill visits to recognize a granulomatous mass in its early stages. If an abnormality is identified, imaging studies are appropriate. Awareness of the condition and vigilance are the keys to successful management of this complication.

Antidepressants are widely used to treat painful chronic rheumatic conditions but, contrary to neuropathic conditions, little is known about their true analgesic properties and value in these situations. Our group, which focuses on pain in rheumatology, aimed to develop recommendations for the use of antidepressants in rheumatology, based on evidence-based review of published data and expert opinion. ⋯ These recommendations for the treatment of painful rheumatological conditions with antidepressants were developed using evidence-based and expert consensus approaches and are the first of their kind in this field. Our review of the literature highlights the need for further, well-designed clinical studies of the use of antidepressants to treat painful rheumatological conditions.

Iatrogenic opioid addiction among chronic pain patients was the initiative for starting a methadone programme for pain patients at the University Hospital of Uppsala. The aims were to improve pain relief and quality of life in pain patients with problematic opioid use and to investigate background factors explaining problems with opioid use. ⋯ A structured methadone programme can be used for treating chronic pain patients with opioid dependence improving pain relief and quality of life. However, side effects and serious adverse events may limit the beneficial effects of the method.

The objective was to determine the association between the prevalence of lower back problems (LBP), fear-avoidance beliefs and pain coping strategies using an analytical cross-sectional epidemiological study among a group of 366 workers in a South African stainless steel industry. Outcome (LBP) was defined using a questionnaire and a functional rating index. ⋯ Significant protective associations were found for increased activity levels (OR 0.57; 95% CI 0.42-0.78). These findings have utility in preventative screening procedures to identify workers with such beliefs and coping strategies who are at risk for prolonged work restrictions.
