Exposure to brain trauma in six age divisions of minor ice hockey.

Acute and chronic neurological risks associated with brain trauma sustained in professional ice hockey has generated concern for youth participants. Minor hockey is a different game when compared to elite players presenting distinctive risk factors for each age division. Objective measures of brain trauma exposure were documented for six divisions in minor ice hockey; U7, U9, U11, U13, U15, U18.

Patient coping and expectations predict recovery after major orthopaedic trauma.

Background: Persistent post-surgical pain and associated disability are common after a traumatic fracture repair. Preliminary evidence suggests that patients' beliefs and perceptions may influence their prognosis.

Methods: We used data from the Fluid Lavage of Open Wounds trial to determine, in 1560 open fracture patients undergoing surgical repair, the association between Somatic PreOccupation and Coping (captured by the SPOC questionnaire) and recovery at 1 yr.

Comparing external and internal validation methods in correcting outcome misclassification bias in logistic regression: A simulation study and application to the case of postsurgical venous thromboembolism following total hip and knee arthroplasty.

Purpose: We assessed the validity of postsurgery venous thromboembolism (VTE) diagnoses identified from administrative databases and compared Bayesian and multiple imputation (MI) approaches in correcting for outcome misclassification in logistic regression models.

Methods: Sensitivity and specificity of postsurgery VTE among patients undergoing total hip or knee replacement (THR/TKR) were assessed against chart review in six Montreal hospitals in 2009 to 2010. Administrative data on all THR/TKR Quebec patients in 2009 to 2010 were obtained.

Comorbid mild traumatic brain injury increases pain symptoms in patients suffering from an isolated limb fracture.

Objectives: This study seeks to evaluate the effects of a mild traumatic brain injury (mTBI) on pain in patients with an isolated limb fracture (ILF) when compared to a matched cohort group with no mTBI (control group).

Patients And Methods: All subjects included in this observational study suffered from an ILF. Groups were matched according to the type of injury, sex, age, and time since the accident.

Acute to chronic pain transition in extremity trauma: A narrative review for future preventive interventions (part 1).

Background: Several studies have been conducted over the last decade that describe the issue of pain and prognostic factors of acute to chronic pain transition post extremity trauma (ET). However, no thorough interventions to prevent chronic pain development in ET patients have yet been proposed.

Objectives: This first part of a series of two articles aimed to provide a comprehensive analysis of literature on the epidemiology of pain post-ET, the impact of persistent pain on ET patients and the relevant biological transformations involved in acute to chronic pain transition.
