Meta Analysis
Single-dose Systemic Acetaminophen to Prevent Postoperative Pain: A Meta-analysis of Randomized Controlled Trials.
The effect of a single-dose systemic acetaminophen to treat postoperative pain has been previously quantified, but the effect of systemic acetaminophen to prevent postoperative pain is currently not well defined. The preventive analgesic effect of acetaminophen has yet to be quantified in a meta-analysis. The objective of the current investigation was to evaluate the effect of a single preventive dose of systemic acetaminophen on postoperative pain outcomes. ⋯ Systemic acetaminophen, when used as a single-dose preventive regimen, is an effective intervention to reduce postoperative pain. It also reduces postoperative nausea and/or vomiting. Doses >1 g were not associated with greater reduction in pain outcomes.

Clinical experience suggests that patients with osteoarthritis (OA) undergoing revision total knee arthroplasty (TKA) experience more chronic complications after surgery compared with patients receiving primary TKA. This study aimed to investigate the difference in pain, mobility, and quality of life (QoL) in patients after revision TKA compared with patients after primary TKA. ⋯ More than twice as many patients have pain after revision surgery compared with patients after primary TKA. Patients after revision TKA surgery have reduced function, poorer QoL, and higher pain intensity compared with patients after primary TKA surgery.

Multicenter Study
The Role of Illness Perceptions in Predicting Outcome Following Acute Whiplash Trauma - A Multicenter 12-month Follow-up Study.
To examine (1) whether the patients' perceptions of their symptoms immediately after the accident and at 3-month follow-up predict working ability and neck pain at 12-month follow-up and (2) the possible changes in patients' illness perceptions during the follow-up period. ⋯ The findings are in line with the common-sense model of illness and previous research demonstrating that patient's expectations for recovery and illness perceptions might influence the course after whiplash injury. Illness perceptions and expectations may provide a useful starting point for future interventions and be targeted in the prevention of chronicity.

Randomized Controlled Trial Multicenter Study
Results of a Pilot Multi-center Genotype-based Randomized Placebo-controlled Trial of Propranolol to Reduce Pain After Major Thermal Burn Injury.
Results of previous studies suggest that β-adrenoreceptor activation may augment pain, and that β-adrenoreceptor antagonists may be effective in reducing pain, particularly in individuals not homozygous for the catechol-O-methyltransferase (COMT) high-activity haplotype. ⋯ Genotype-specific pain medication interventions are feasible in hospitalized burn patients. Propranolol is unlikely to be a useful analgesic during the first few weeks after burn injury.

To determine the persistence of chronic pain among community-dwelling older persons and to identify factors related to persistent chronic pain. ⋯ Chronic musculoskeletal pain is a highly persistent condition among community-dwelling older persons and it is related to poor health and mobility difficulties. In addition, the use of daily analgesic is low despite the continuous nature of chronic pain.
