Vascularized composite allotransplantation (VCA) has demonstrated utility in the reconstruction of extensive soft-tissue defects following severe burns. However, pre-VCA events such as multiple transfusions, previous transplantation and pregnancies, the use of skin allografts, and mechanical support devices may result in sensitization and ultimately exclude a burn patient, who may benefit most through VCA, from a hand or face transplant. The authors sought to identify the immunologic challenges involved. All reported VCA cases up to July 2016 were reviewed...

There is a real risk of electrical accidents in the operating theatre, with the growing number of electrical, electronic and flammable liquids used. Electrocautery remains the most commonly used device for its electrosurgical effect of coagulation or tissue section. When it is defective or misplaced on a small area of the skin, it can cause a typically deep, slow healing skin burn. It adds an unexpected iatrogenic morbidity to the initial condition, with devastating consequences for the patient, the surgeon and sometimes the hospital...

Exchange of components such as particles and cells in droplets is important and highly desired in droplet microfluidic assays, and many current technologies use electrical or magnetic fields to accomplish this process. Bead-based microfluidic techniques offer an alternative approach that uses the bead's solid surface to immobilize targets like particles or biological material. In this paper, we demonstrate a bead-based technique for exchanging droplet content by separating fluorescent microparticles in a microfluidic device...

A 72-year-old male reported a long-standing history of unexplained syncope. Stress echocardiography demonstrated inducible anterior hypokinesis, and he proceeded to percutaneous coronary intervention for an 80% stenosis of the left anterior descending artery. Thirty minutes post-procedure, he experienced a pulseless electrical activity (PEA) cardiac arrest. Urgent repeat angiography demonstrated profound coronary artery spasm consistent with Kounis syndrome. Three days later, a second PEA arrest occurred. Systemic mastocytosis was ultimately diagnosed as the cause of his recurrent syncopal episodes and cardiac arrests...

Myocardial infarction (MI) following high voltage electric burn is very rare, and its pathogenesis remains controversial. Electrical burns represent only 4% of all burns. Hence, clinical managements have taken a slow pace in developing. The recent guidelines laid down by the cardiology societies include cardiac troponin I (cTnI) as the gold standard marker for the assessment of myocardial damage assessment. Two patients were admitted to our hospital at the different time with the same kind of high voltage electric burn...

Low temperature plasma (LTP) coagulation equipment, which avoids causing burn injuries to patients, has been introducing into minimally invasive surgery. The mechanism by which this equipment stops bleeding is to directly occupy the injury with the formed blood clots, and different from the mechanism of the common electrical hemostatic devices that cauterize the tissues around the bleeding to stem the blood flow. A noteworthy point is that LTP treatment with our equipment is not confined only to the blood coagulation system, but it has significant effects on the other blood components to form clots with or without hemolysis, and that there is a plasma current threshold that determines whether the treatment makes stable clots...

Objective: To investigate the repair mechanisms of the wounds with bone exposed by artificial dermis transplantation. Methods: Seventy two rabbits were randomly divided into 3 groups of 24 rabbits, the wound model was made on the top of head. In the skin defect group (SD group), skin was removed and skull periosteum was retained. In the periosteal defect group (PD group), the skin and skull periosteum were both removed, and the skull was exposed. In the skull burn group (SB group), after the periosteum was removed, the exposed skull bone was burned out with electric iron to cause skull surface necrosis, then the artificial dermis transplantation were performed in each group...

Currently, electronic cigarette (EC) devices are widely used as an alternative to conventional smoking. The underlying technical principle is an electric coil-based vaporizer unit, which vaporizes various solutions for inhalation purposes with a rechargeable lithium battery unit as power source. We report a case of extensive burn injury resulting from the thermal explosion of a battery unit within an EC device. Though internal thermal instabilities of lithium ion batteries are a known safety issue, the unique feature here is a pronounced amplification of the extent of burn injury due to an additional scalding burn mechanism that resulted from heating of the liquid reservoir adjacent to the battery...

Delayed complications of electrical burns are mostly unexpected, and the link between the injury and the symptoms often goes unrecognized. A possible relation between source-ground sites and late clinical manifestations was recently emphasized. We report a unique case of combined intestinal-spinal delayed complications following a high-voltage electrical injury, a possible explanation being a greater current flow through the right hemisoma. The potential for late complications is an additional feature that physicians must consider in managing electrical injuries...
