To survey the prevalence of pain in patients admitted to different hospitals of Catalonia and to describe which factors are related to pain. ⋯ A high prevalence of clinically relevant pain in in-patients was found as well as a great variability according to type of patients, clinical wards and hospitals. This study gives clear evidence of the lack of adequate management of pain in the majority of the hospitals and calls for the implementation of organisational and educational measurements that may settle this epidemic problem.

Randomized Controlled Trial Comparative Study
Reduction of human experimental muscle pain by alfentanil and morphine.
Musculoskeletal pain is a major clinical problem. By using various experimental models in humans, the understanding of the basic mechanisms behind muscle pain can increase, thereby giving hope for new and optimized treatment. Opioids are increasingly often used to treat muscle pain. ⋯ In conclusion, this is the first study to compare two high doses of alfentanil and morphine on experimental muscle pain in humans. Both alfentanil and morphine reduced experimental muscle pain. There were no indications of any true pharmacodynamic differences between the two drugs.

In LBP patients, the relationship between pain and physical activity remains unclear. Whereas a negative relationship between pain and self-reported physical activity was found, this relation disappeared in the case of overt behavioral data (e.g., accelerometer). Cognitive-behavioral models of the development of chronic pain suggest subgroups with signs of physical underuse and overuse. ⋯ The assessment of pain-related coping modes yielded an important differentiation between subgroups of LBP patients 6 months after surgery. Endurance copers displayed signs of overuse in their daily behavior in spite of pain than adaptive copers. The one fear avoidance coper tends to do less physical activity in the sense of underuse.

Post-herpetic neuralgia (PHN) following acute herpes zoster remains a significant cause of neuropathic pain especially in the elderly. Early treatment of the zoster rash with antiviral agents, such as aciclovir remains one of the few measures proven to reduce the incidence and duration of PHN albeit only in a subset of patients. It is therefore crucial that the physician who first sees a case of zoster identifies those patients who are most likely to develop long-term pain and treats them accordingly. ⋯ A visual analogue score (VAS) over 5 and/or age over 50 correctly identified all subjects with PHN at 3 and 6 months, respectively. However, the specificity of this prediction was low because as many as 81% and 85% of those aged over 50 recovered within 3 and 6 months, respectively. Better methods are needed to identify patients over 50 at most risk of PHN that enable GPs to better allocate their resources with respect to HZ treatment.

Complex regional pain syndrome (CRPS) is a disorder characterised by pain, sensory and motor disturbances and represents a significant medical entity. This report discusses two cases of CRPS in children and adolescents, highlighting several critical issues for clinicians in the diagnosis and management of CRPS in these populations. Early diagnosis, referral and appropriate intervention are essential in decreasing pain, suffering and resorting function for children and adolescents with CRPS.
