Opioid-induced bowel dysfunction (OIBD) is an increasing problem due to the common use of opioids for pain worldwide. It manifests with different symptoms, such as dry mouth, gastro-oesophageal reflux, vomiting, bloating, abdominal pain, anorexia, hard stools, constipation and incomplete evacuation. Opioid-induced constipation (OIC) is one of its many symptoms and probably the most prevalent. The current review describes the pathophysiology, clinical implications and treatment of OIBD. ⋯ It is the belief of this Nordic Working Group that increased awareness of adverse effects and OIBD, particularly OIC, will lead to better pain treatment in patients on opioid therapy. Subsequently, optimised therapy will improve quality of life and, from a socio-economic perspective, may also reduce costs associated with hospitalisation, sick leave and early retirement in these patients.

Real-life data on laxative use in patients suffering from opioid-induced constipation (OIC) are very limited, and many OIC patients are only using over the counter laxatives to resolve their constipation. Our aim was to describe laxative utilization and quality of life in participants in Norway who ever experienced OIC. ⋯ Patients suffering from OIC with low quality of life and remaining symptoms despite use of two or more laxatives are a vulnerable patient group in need of optimized healthcare management, who also might benefit from more specific and innovative therapy.

To provide effective and accurate radiotherapy (RT) for advanced cancer patients who experience breakthrough pain (BP) due to positioning manoeuvres, through the use of FPNS. Secondary endpoints were the dose and time required to achieve a 50% numeric rating scale (NRS) reduction and conduction of a pharmacoeconomic analysis. ⋯ Certain necessary RT procedures in advanced cancer patients can cause severe BP episodes. A simple, safe, fast acting and strong analgesic is needed. FPNS is a rapidly absorbed opioid analgesic with a pain relief profile that would be particularly well suited for this patient population. By reducing BP, the drug enables the completion of necessary RT procedures without needless patient discomfort. When BP is attenuated, Department productivity is maintained and unnecessary delays are avoided. Further studies and clinical trials are needed to assess therapeutic FPNS dosages with a view to defining efficacy in the correct clinical context.

Nursing documentation supports continuity of care and provides important means of communication among clinicians. The aim of this topical review was to evaluate the published empirical studies on postoperative pain documentation in a hospital setting. ⋯ Comprehensive auditing tools for evaluation of pain documentation can make quality assessment easier and coherent. Specific and clear documentation guidelines are needed and existing guidelines should be better implemented into practice. There is a need to increase nurses' knowledge of postoperative pain management, assessment and documentation. Studies evaluating effectiveness of high quality pain documentation are required.

Non-nociceptive somatosensory input, such as tactile or proprioceptive information, always precedes nociceptive input during a painful event. This relationship provides clear opportunities for predictive associative learning, which may shape future painful experiences. In this differential classical conditioning study we tested whether pain-associated tactile cues (conditioned stimuli; CS) could alter the perceived intensity of painful stimulation, and whether this depends on duration of the CS-seeing that CS duration might allow or prevent conscious expectation. ⋯ Pain-associated visual and auditory cues have been shown to enhance pain in laboratory and clinical scenarios, supposedly by influencing expectation of impending harm. We show that pain-associated somatosensory cues can also modulate pain and that this can occur independently of expectation. This points to a larger potential role for associative learning in the development and treatment of pain than has previously been considered. We suggest that research into associative mechanisms underpinning pain, as distinct from those that link pain to pain-related fear and avoidance, is worthwhile.
