Randomized Controlled Trial
Ketamine does not reduce postoperative morphine consumption after tonsillectomy in children.
Tonsillectomy is one of the most frequently performed operations in children and frequently associated with moderate-to-severe pain. ⋯ The addition of ketamine 0.25 mg/kg at induction of anesthesia did not decrease postoperative morphine consumption in children undergoing tonsillectomy.

Correlates of pain-rating concordance for adolescents with sickle cell disease and their caregivers.
As sickle cell pain in children and adolescents with sickle cell disease (SCD) is managed primarily at home, understanding convergence of caregiver and youth pain reports may contribute to improvements in home pain management. The goal of this study was to examine concordance in pain ratings for a sample of 53 adolescents with SCD and their caregivers and to assess sociodemographic and psychosocial factors associated with concordance. ⋯ Efforts to improve home management of pain in SCD should incorporate programming designed to increase parent-child communication about pain and pain interference, confidence in disease management abilities, and improved knowledge of SCD and its care, particularly for families of older adolescents.

Deep cross-friction pressure with a finger or an elbow in the proximal gluteal region causes a sciaticlike pain along the side of the thigh and the leg as a clinical presence of referred pain (RP) in patients with nonspecific low back pain (LBP). This study investigated the reliability and discriminative ability of experimentally provoked RP as a result of deep cross-friction with the aid of a Fischer algometer. The new clinical examination method measures the provoked RP threshold resulting in an outcome, expressed in kg/cm2. ⋯ This clinical study support the reliability and discriminative ability of a new method of experimentally provoked RP, using deep cross-friction pressure with the aid of a Fischer algometer in patients with LBP. The experimentally "provoked referred pain threshold" (PPT-RP) values lower than 6 kg/cm correspond clinically with the presence of a referred muscle pain area in the thigh and/or the leg. Further studies of a similar kind are nevertheless needed to confirm those conclusions and to assess the responsiveness of the provoked RP measurements in different treatment follow-up periods.

There is no consensus among experts regarding the etiology or management of patellofemoral pain syndrome (PFPS). Observations indicating dysfunction of the peripheral nervous system around the patellae have been reported. To what extent these sensory abnormalities cause pain has so far not been investigated. The aim of this study was to assess whether a subgroup of patients with unilateral PFPS have neuropathic pain related to the painful knee. ⋯ This study hypothesizes that the observed sensory aberrations may cause neuropathic pain in patients with PFPS. There is no validated method for subgrouping patients with possible neuropathic pain and in this study considerable heterogeneity and overlap regarding signs and symptoms of neuropathic pain made subgrouping even more difficult. A mechanism-based understanding of the pain is, however, essential for the selection of adequate treatment strategies in painful musculoskeletal disorders.

Though eating disorders (EDs) are associated with numerous physiologic complications, very little research has examined subjective reports of pain and pain-related risk factors in patients with EDs. ⋯ Depression and pain are intimately related in EDs. Future investigations should characterize patients who present with elevated pain and examine the relationship between pain, psychologic factors, and treatment outcome.
