Isokinetic dynamometry is used during exercise testing and rehabilitation to obtain a quantitative strength measurement on which progressive strength training programs can be based. This study assesses the test-retest reliability of isokinetic leg function in the knee flexors and extensors at 150 degrees/second in children and young adults with severe burns to be used for rehabilitation exercise program prescription. In 39 severely burned patients (49 ± 14% total body surface area burn [TBSA], mean ± SD; 34 ± 21% TBSA 3 rd degree; 14 ± 5 years, 153.3 ± 16.5 cm height; 53.8 ± 17.9 kg) knee flexion/extension isokinetic dynamometry at 150 degrees/second was performed on each patient's dominant leg in two sessions. ⋯ Sessions did not differ significantly in knee extension or flexion for any muscle function outcome or the hamstrings to quadriceps ratio. All intraclass correlation coefficients were >0.89 and r2 >0.79. Test-retest isokinetic dynamometry functional measurements in the knee flexors and extensors at 150 degrees/second are reliable in the burn population and may aid resistance rehabilitation program prescriptions.

Over the years, many cultures have used herbs for serious health problems. Garlic (Allium sativum) pose hypocholesterolemic, fibrinolytic, antidiabetic, and antibiotic actions. However, it has unusual adverse effects such as chemical burns and contact dermatitis when used topically. In this case report, the authors present two cases of topical garlic burn caused after the use of crushed garlic with a bandage for pain relief due to arthritis.

Hypertrophic scar (HTS) occurs frequently after burn injury. Treatments for some aspects of scar morbidity exist, however, dyspigmentation treatments are lacking due to limited knowledge about why scars display dyschromic phenotypes. Full thickness wounds were created on duroc pigs that healed to form dyschromic HTS. ⋯ MiTF expression was not different upon further exploration, but TYR, TYRP1, and DCT were upregulated in intact biopsies measured by qRT-PCR and confirmed by immunostaining. This is the first work to confirm the presence of melanocytes in hypopigmented scar using qRT-PCR and primary cell culture. An understanding of the initial steps in dyspigmentation signaling, as well as the downstream effects of these signals, will inform treatment options for patients with scars and provide insight to where pharmacotherapy may be directed.

Burn size estimation is a crucial component of acute burn management that guides referral to burn centers, fluid resuscitation parameters, hospital resource distribution, and mortality-based interventions. Referring providers often misestimate the total BSA (TBSA) of burn injury, which contributes to unnecessary healthcare costs, misappropriation of limited resources, and delay in provision of appropriate patient care. A systematic literature review of articles available on PubMed, Scopus, Google Scholar, OvidSP Medline, and Web of Science was performed. ⋯ TBSA misestimation is associated with an increased incidence of inappropriate transfers to burn centers and the associated costs. The data remains lacking, however, and larger studies are required to further elucidate the clinical impact of such errors. A systematic approach with telemedicine-facilitated computer-based burn assessments is required.

Acute kidney injury (AKI) is a common and morbid complication in patients with severe burn. The reported incidence of AKI and mortality in this population varies widely due to inconsistent and changing definitions. They aimed to examine the incidence, severity, and hospital mortality of patients with AKI after burn using consensus criteria. ⋯ Presence of and increasing severity of AKI are associated with increased hospital mortality. AKI appears to be independently and strongly associated with mortality in patients with TBSA ≤ 40%. Further investigation to develop risk-stratification tools tailoring this susceptible population is direly needed.
