To describe the largest case series of lower extremity traumatic internal degloving injury, i.e. Morel-Lavallée lesion (MLL) in the pediatric and adolescent population, its treatment and outcomes. ⋯ In contrast to adult injury literature, pediatric MLLs are more common in the leg/knee than hip/thigh region and caused mostly by sports injuries. Primary care physicians are the initial treating providers for the majority of the patients. Intervention is more often needed in the hip/thigh MLLs as opposed to non-operative management for lower leg injuries. This large case series on MLL in the pediatric population demonstrates differences in the management of hip and thigh lesions when compared to the management of the knee and leg lesions in the majority of these patients. Non-operative management in the majority of these lesions provided overall satisfactory outcomes.

Objectives: To describe the incidence, magnitude, and distribution of head impacts and track concussions sustained in a collegiate level women's rugby season. Methods: Data on head impact incidence and magnitude were collected via Smart Impact Monitors (SIM) (Triax Technologies, Inc., Norwalk, CT) within fitted headbands during practices and games of one competitive season. Magnitude data included peak linear acceleration (PLA) and peak rotational velocity (PRV) measurements and were reported as median [IQR]. ⋯ Four concussions were reported and monitored. Conclusion: The incidence and magnitude of head impacts in collegiate level women's rugby over one season of practices and games were fewer than those reported in other comparable studies. These findings give insight into the impact burden that female collegiate rugby athletes withstand throughout a competitive season.

Introduction: The purpose of this study was to evaluate the efficacy and safety of adipose-derived stem cell (ADSC) or stromal vascular fraction (SVF) injections for knee osteoarthritis (OA) treatment by analyzing all randomized controlled trials dealing with this topic. Materials and methods: The following search terms were used in PUBMED, EMBASE, Scopus, and the Cochrane Library Database on 14 November 2019: 'adipose derived stem cell' OR 'stromal vascular fraction' OR 'SVF' OR 'multipotent mesenchymal stromal cells' OR 'stem cell' OR 'derived stem cell' OR 'autologous' AND 'knee' OR 'osteoarthritis' OR 'chondral defect' OR 'randomized' OR 'controlled trial.' No time limit was given to publication date. We included randomized controlled trials (RCTs) based on the following criteria: (1) English studies; (2) patient population diagnosed with knee OA and treated with ADSCs or SVF injections; (3) comparison group treated with placebo, surgery, or adjuvant injections, such as platelet rich-plasma or hyaluronic acid. ⋯ However, the length and modalities of follow-up in the different conditions are extremely variable. Nevertheless, it appears that the use of adipose-derived stem cells is associated with clinical and radiological improvements and minimal complication rates. To avoid bias deriving from the use of biological adjuvants or surgical procedures, randomized controlled trials comparing ADSCs or SVF and other treatments (for example, platelet rich-plasma or hyaluronic acid injections) should be performed.

Objectives: To identify the availability and accessibility of AEDs in Irish GAA clubs and the knowledge, willingness, and confidence of club members to use AEDs in a medical emergency. Methods: A self-report survey was completed anonymously by GAA club members (n = 267). The survey captured demographic information, previous formal AED training, awareness of AED access in their local GAA club and knowledge, confidence, and willingness to use an AED in a medical emergency and awareness of a written club emergency action plan (EAP). ⋯ Conclusion: To ensure the chain of survival works effectively it is essential that an AED is available, is accessible, and that club members know its location, know when to use it, and are willing and confident to use it. GAA clubs should design an individual emergency action plan and disseminate it widely among club members. Formal AED training should be encouraged among club members and at least one trained member should be present during all club activities.
