Objectives Bowel dysfunction is a major complication following open surgery for invasive cancer of the bladder that results in significant discomfort; complications and can prolong the length of stay. The incidence of postoperative ileus following open radical cystectomy has been reported as 23-40%. The median length of hospital stay after this surgery in the United Kingdom is 11 days. ⋯ There was no significant difference in rescue analgesia (intravenous tramadol) consumption. Complete avoidance of systemic morphine played a key role in improved outcomes. Conclusions ESPITO was successful in reducing postoperative ileus and length of hospital stay after open radical cystectomy when compared to standard analgesia within an enhanced recovery programme.

Background and aims This prospective study aimed to assess pressure pain thresholds (PPTs) by pressure algometry and the correlation to postoperative pain in children undergoing orthopaedic surgery. We hypothesized, that the PPTs would decline immediately after elective orthopaedic surgery and return to baseline values at follow-up. Methods Thirty children aged 6-16 years were included. ⋯ This suggests that other factors than surgery modulate the threshold for pain. Implications Awareness of pressure pain thresholds may help identify children with affected pain perception and hence improve future pain management in children undergoing orthopaedic surgery. Factors as for example anticipatory anxiety, psychological habitus, expected pain, catastrophizing, distraction, physical activity, patient education and preoperative pain medication might play a role in the perception of pain and need further investigation.

Observational Study
Revised chronic widespread pain criteria: development from and integration with fibromyalgia criteria.
Background and aims Persons with chronic widespread pain (CWP) have poor medical outcomes and increased mortality. But there are no universally accepted criteria for CWP or of methods to assess it. The most common criteria come from the 1990 American College of Rheumatology (ACR) fibromyalgia (FM) criteria, but that method (WP1990) can identify CWP with as few as three pain sites, and in subjects with wide differences in illness severity. ⋯ Implications Definitions of CWP in research and clinic care are arbitrary and have varied, and different definitions of CWP identify different sets of patients, making a universal interpretation of CWP uncertain. In addition, CWP is a mandatory component of some fibromyalgia criteria. Our study provides quantitative data on the differences between CWP definitions and their criteria, allowing better understanding of research results and a guide to the use of CWP in clinical care.

Randomized Controlled Trial
A randomized study to evaluate the analgesic efficacy of a single dose of the TRPV1 antagonist mavatrep in patients with osteoarthritis.
Transient receptor potential vanilloid type 1 (TRPV1) receptor antagonists have been evaluated in clinical studies for their analgesic effects. Mavatrep, a potent, selective, competitive TRPV1 receptor antagonist has demonstrated pharmacodynamic effects consistent with target engagement at the TRPV1 receptor in a previous single-dose clinical study. The current study was conducted to evaluate the analgesic effects of a single dose of mavatrep. ⋯ Further studies are required to evaluate whether lower multiple doses of mavatrep can produce analgesic efficacy while minimizing adverse events, as well as the potential for improved patient counselling techniques to reduce the minor thermal burns related to decreased heat perception.

Previous research has highlighted the importance of cognitive appraisal processes in determining the nature and effectiveness of coping with chronic pain. Two of the key variables implicated in appraisal of pain are catastrophizing and perceived injustice, which exacerbate the severity of pain-related distress and increase the risk of long-term disability through maladaptive behavioural responses. However, to date, the influences of these phenomena have not been examined concurrently, nor have they been related specifically to quality of life measures, such as life satisfaction. ⋯ The current findings highlight the distinct affective and behavioural mediators of pain and maladaptive cognitive appraisal processes in chronic pain, and highlight their importance in both perceptions of pain-related interference and longer-term quality of life.
