A Multifaceted Approach to Interpreting Reaction Time Deficits After Adolescent Concussion.

Context: Reaction time (RT) is a critical element of return to participation (RTP), and impairments have been linked to subsequent injury after a concussion. Current RT assessments have limitations in clinical feasibility and in the identification of subtle deficits after concussion symptom resolution.

Objectives: To examine the utility of RT measurements (clinical drop stick, simple stimulus-response, single-task Stroop, and dual-task Stroop) to differentiate between adolescents with concussion and uninjured control individuals at initial assessment and RTP.

Graves'-induced prothrombotic state and the risk of early-onset myocardial infarction.

Hyperthyroidism represents a state of hypercoagulability and hypofibrinolysis, which predisposes an individual to the increased risk of thromboembolism. We present a case of a 25-year-old patient presenting with an acute myocardial infarction secondary to plaque rupture with thrombotic occlusion of proximal left anterior descending artery, in a patient known to have Graves' disease. She had a sudden ventricular fibrillation arrest and a precordial thump given and cardiopulmonary resuscitation started.

Laparoscopic versus open appendicectomy in children: a UK District General Hospital experience.

Aims: The aim of this study was to evaluate the potential role of laparoscopic appendicectomy in reducing morbidity and length of stay in children compared to open procedures in a UK District General Hospital setting.

Methods: A three-year retrospective review of children ≤ 15 years with histologically confirmed appendicitis who underwent laparoscopic (LA) and/or open (OA) appendicectomy was performed. Choice of operation was based on individual surgeon's preference and on patient's body size.
