ABSTRACT
Crushing burn injury on the hand is relatively rare these days. Still, the effect of the combined thermal and press damage is very severe, and, therefore, the deformity or disability of the hand is often the consequence of the accident. Early aggressive debridement or fasciotomy is preferred for the treatment after admission. We present an extremely severe burn case: the patient has had a full-thickness third-degree hot crushing injury on the hand with all dermal elements, muscles, and tendons destroyed.
ABSTRACT
Postburn scar and contracture (PBSC) occur after severe burn injuries, and the deformity causes functional problems in the patients. The patients have difficulty even with simple everyday tasks, so their socioeconomic status seems to be limited or rather to be in a poor stage. This makes the quality of their daily life very low. Certainly, sooner or later, the postburn contracture release operation is performed to restore the functions such as flexion, extension, rotation, and other movements of the injured region. We present the case of a patient who has suffered PBSC for an extended period, and, at last, she has had a PBSC releasing operation with the composite skin graft, split-thickness skin graft with a dermal substitute.
ABSTRACT
Traumatic lip injury is one of the most common clinical conditions in facial injuries. Nonetheless, the degree of the convex and concave slopes on the vermilion border appears to be unique and dynamic; therefore, the reconstruction of the lip defect is always challenging for plastic surgeons [1]. We present a patient who fell off a motorcycle at speed and had a severe friction burn injury with a significant loss of the skin and soft tissue on the left lower lip.
ABSTRACT
PURPOSE: This study was designed to better understand the mechanism of low temperature burn and to show clinical cases of low temperature burn. METHODS: The local temperature increase of electric pad was investigated at 4 different surface cooling conditions. Blocks (5x5x2 cm3) made of silicone rubber, aluminum, or urethane foam were placed on the top of the electric pad, and temperature between the blocks and electric pad was measured up to 7 hours after switching on maximally (level 7). Each block has different thermal conductivity (TC) and TC of silicone rubber (0.2 W/m.degrees C) is similar to TC of human skin (0.37 W/m.degrees C). TC of aluminum is higher and TC of urethane foam is lower than TC of human skin. Experiments were performed on two occasions with or without a blanket covering over the electric pad and blocks. RESULTS: The initial surface temperature (18degrees C) of the electric pad under the silicone rubber block was elevated to 36.5degrees C at 1 hour, 41.8degrees C at 3 hours, 44.2degrees C at 5 hours, and 45.5degrees C at 7 hours. After covering the electric pad and blocks with a blanket, the temperature of the electric pad under the silicone rubber block was elevated to 40.9degrees C at 1 hour, 51.8degrees C at 3 hours, 56.1degrees C at 5 hours and 58.1degrees C at 7 hours. Under the same conditions, surface temperatures under the urethane foam and aluminum blocks were 70.8degrees C and 50.degrees C respectively at 7 hours. CONCLUSION: The local temperature increase of electric pad was dependent on the surface cooling conditions, heating time and blanket covering over the electric pad. The surface temperature increased to 56.1degrees C at 5 hours after blanket covering over the silicone block which temperature can cause severe injuries on the human skin within a minute.
