Comparative Study
Changes in pain perception and descending inhibitory controls start at middle age in healthy adults.
Previous studies have shown a reduction of diffuse noxious inhibitory controls (DNICs) in elderly adults compared with younger adults. Unfortunately, little is known regarding the developmental course of DNIC deficits and so it is still unclear whether middle-aged adults also show a DNIC deficit. The aims of the present study were to better characterize the developmental time course of the change in DNIC response by adding a middle-aged group. The role of expectations was also investigated. ⋯ The findings tell us that changes in pain perception and endogenous pain modulation arrive earlier than previously suggested. Studies on aging and pain should include a middle-aged group when comparing pain measures across the adult lifespan.

First to compare pain and functional disability in tennis elbow (TE) patients with healthy controls. Second, to evaluate the relationship between the 2 major psychologic factors (anxiety and depression) and TE. ⋯ TE patients showed markedly increased pain and functional disability. Significantly elevated levels of depression and anxiety pointed out the importance of psychologic assessment in TE patients. In the development of supportive and treatment strategies, we suggest the combination of "upper limb" and "psychologic" assessment tools.

Although a great variety of surgical procedures are performed on an ambulatory basis, little is known about postoperative pain experience at home after ambulatory surgery. This study was performed to assess the prevalence and course of postoperative pain in the early postoperative period after ambulatory surgery. ⋯ This study showed that an important number of patients still experience moderate to severe pain in the postoperative period after day-case surgery even after a 4-day period. Furthermore, the type of operation should be considered when planning postoperative analgesia for ambulatory surgery.

Central neuropathic pain occurs in around 28% of patients with multiple sclerosis (MS). The Neuropathic Pain Scale (NPS) has received preliminary validation in peripheral neuropathic pain conditions. The aim of this study was to validate its use in MS central pain syndromes. ⋯ The NPS appears a useful tool in the assessment of neuropathic pain in MS patients and possibly in measuring outcomes of therapeutic interventions.

Use of a valid behavioral measure for pain is highly recommended for critically ill, uncommunicative adults. The aim of this study was to validate the English version of the Critical-Care Pain Observation Tool (CPOT) and physiologic indicators [mean arterial pressure, heart rate, respiratory rate, and transcutaneous oxygen saturation (SpO(2))] in critically ill ventilated adults. ⋯ The CPOT is a reliable and valid tool to assess pain in critically ill adults. Behavioral indicators represent more valid information in pain assessment than physiologic indicators. Further research is needed to explore how specific critically ill populations (eg, head injury) react to a painful procedure.
