The aim of the present study was to assess the role of protein kinase C (PKC) in the development of cardiac injury following scald burn. Sprague-Dawley rats were induced a scald burn a 15% total body surface area. Phorbol 12-myristate 13-acetate (PMA, 2 mg/kg) and bisindolylmaleimide (BIS, 0.05 mg/kg) were immediately administered i.p. after burn injury. 5 h and 24 h later, heart was removed and examined biochemical assay, ultrastructural changes and stereological analysis. The activity of serum aspartate aminotransferase was significantly increased at 5h (p<0.01) and 5h+BIS (p<0.001) after burn compared with that of control. The activity of serum creatinine was significantly decreased in PMA-treated groups after burn compared with postburn 5 h. PMA caused a decrease in MPO activity and induced wavy fibers in cardiac myocytes at postburn 5 and 24h. BIS induced contraction band, separation of intercalated disk and abnormal mitochondria in cardiac myocytes at postburn 5 and 24h. In stereological analysis, treatment of rats with PMA increased volume density of myofibril and mitochondria compared with postburn 5 and 24h. Our data suggest that the activation of PKC in scald burned heart decreases inflammation and protects the myocardium.

Purpose: Pediatric burn still generates social problem leading to physical and mental sequelae for ages. We studied to help make a program for the prevention of pediatric burn. Methods: We analyzed retrospectically 2759 acute burn patients under the age of 15 years in recent 5years (January 2000 - December 2004). Results: 1553 males and 1226 females were investigated, with a male to female ratio of 1.25 : 1. The greatest number of burn patients were those with an age of 1 - 2 years(1435, 52%). Scalding burn was the most common cause of injury, which accounted for 1980 (71.8%) patients, followed by contact burns(286, 10.4%), flame burn(229, 8.3%), steam burn(141, 5.1%). Especially steam burn was the second cause of injury in the age under 1 year, while flame burn was the same in the age over 3 years. During recent 5 years, incidence of contact burn increased over twofold despite the others did not changed substantially. Variation of seasonal incidence is minimal and most of the patients(2545 cases, 92.2%) had burns of ${\leq}20%$ TBSA. The median hospital stay was 18.3 days, and the rate of operation was 35.4% with an high rate in electrical burn(70.6%), steam burn(68.8%), contact burn(65%). 27 patients died in this series, which yielded a mortality rate of 1%. Conclusion: We expect that these data will be used as a basis for prevention of pediatric burn.

Purpose: We accessed epidemioloy of 908 acute burns (7 years) in the military, of injuries and propose proper educational programs to suit community. Methods: We surveyed burn demographics, circumstances of injuries, size, result of treatment. Results: The mean age was 20.6 years. The flame burns (FB) (325, 35.8%) were most common, followed scald (SB) (305, 33.6%), contact (CB) (219, 24.1%), electric (EB) (45, 5.0%) and chemical burns (ChB) (14, 1.5%). The more occurred during winter (29.7%). SB had mean 3.9% total body surface area (TBSA). The 251 (82.3%) had superficial burns by spillage of hot water/food on lower limbs (45.6%), feet (33.8%) in summer (34.8%), treated with simple dressing (92.8%). Morbidity rate was 5.6%; post traumatic stress disease (PTSD) (0.7%). FB had large wound (9.3% TBSA). The 209 (64.3%) had superficial burns by ignition to flammable oils (31.7%) and bomb powders (29.2%) on head/neck (60.3%), hands (58.6%) in summer (31.7%), autumn (30.2%). They underwent simple dressing (83.4%) and skin graft (16.0%). Morbidity rate was 18.8%; PTSD (10.5%), inhalation injuries (4.0%), corneal injury (3.7%), amputations (0.9%), and mortality rate (1.2%). CB had small (1.1% TBSA), deep burns (78.5%) by hotpack (80.4%) on lower limbs (80.4%). The more (59.8%) underwent skin graft. EB had 6.8% TBSA. The 29 (64.4%) had superficial burns by touching to high tension cable (71.1%) on hand (71.1%), upper limbs (24.4%) in autumn (46.8%). They underwent simple dressing (71.1%) and skin graft (24.4%). They showed high morbidity rate (40.0%); loss of consciousness (13.3%), nerve injuries (11.1%), neuropathy (8.9%), amputations (2.2%), and mortality rate (2.2%). Conclusions: The cook should wear apron over the boots during work. The lighter or smoking should be strictly prohibited during work with flammable liquids or bomb powders. Don't directly apply hotpack to skin for a long time. Use insulating glove during electric work. Keep to the basic can prevent severe injury and proper education is important.

Background: To study the role of spinal alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptors in pain behaviors caused by mild burn, we examined the effect of intrathecal administered ACEA 2085, which has been recently characterized as a high potency competitive AMPA receptor antagonist, on the thermal hyperalgesia state induced by mild burn. Methods: A thermal injury was induced by applying the left hind paw to a thermal surface ($52.5^{\circ}C$) for 45 sec. Thermal escape latency of the hind paw was determined using an underglass thermal stimulus. Thirty min after thermal injury, the paw withdrawal latency (PWL) in injured paw of all groups fell from 10~12 sec to 5~7 sec. At that time, ACEA 2085 (0.01~0.1 mcg) and 6-cyano-7-nitroquinoxalinedione (CNQX, 1~30 mcg) were injected through intrathecal heters in rats with mild burn injury on the right hindpaw. And then, PWL were measured in the both hindpaw every 30 minutes for about three hours. Results: The intrathecal injection of ACEA 2085 produced a dose dependent reversal of the hyperalgesia in the right hindpaw and more potent than CNQX, but had no effect upon the response latency of the normal left hind paw even at the largest doses. All effects were observed at doses that had no significant effect upon motor function. Conclusions: Intrathecal ACEA 2085, highly selective AMPA receptor antagonist produce a dose- dependent reversal of the thermal hyperalgesia evoked mild burn injury. These results suggested that spinal AMPA receptor play an important role in the hyperalgesia induced by mild burn injury.

Nowadays, microwave ovens are commonly used for cooking. However, the cooking certain food in microwave ovens can be hazardous. It has been reported that the heating eggs in a microwave oven can cause an explosion and injuries. The exploding eggs can cause burn injury of face, neck, eyelid, pharynx and larynx. Direct thermal damage to the larynx after swallowing microwave-heated eggs is rare. The authors report a larynx thermal injury due to microwave-heated eggs and review the cause and the prevention methods of exploding eggs.

Recently, the usage of an exercising treadmill has increased in Korean homes. Along with increasing utilization of these machines, injuries relating to the inadvertent usage of the machine have gradually increased for the last several years. The purpose of this study is to identify the feature of this type of injury, thereby to help prevent and to raise an awareness of the potential injury. 25 patients who had been admitted to Hangang Sacred Heart Hospital from January 2002 through March 2004 were investigated retrospectively. Age, sex, place of injury, the area and the extent of injury, treatment and prognosis were analyzed for each case. All injuries involved in the children with an average age of 3.5 years. This new type of injury was at least a deep second-degree burn of the friction-burn type in all cases. Most of them primarily involved hands. Inattention of the guardian was the main cause of such injuries. 68% of the cases needed an operation such as a split-thickness skin graft or a full-thickness skin graft. In this study, authors reached a conclusion that such injuries may be prevented by an education of the potential risks of using a treadmill and by developing additional safety devices.

Soft tissue calcifications after burn injuries are commonly found in the periarticular region. They can easily be found because they cause severe pain and distress to the patient. However, a long period is required to identify extra-articular soft tissue calcification after burn injuries because they have no specific symptoms. Herein, we present the case of a patient with dystrophic extra-articular soft tissue calcification after a burn injury. A 70-year-old woman developed a non-healing ulcer in the right lower leg area two months before presentation to the hospital. She had third-degree flame burns on the anteromedial tibial area of the right leg approximately 40 years prior, and there had been no particular problem. Examination revealed chronic ulcers, and a review of radiograph findings revealed irregular calcification. The wound was treated with wide excision with a skin graft, and it healed without complications. During follow-up one month later, no recurrence of the calcification or ulceration of the lesion was found.

Burn is a dermal injury mainly caused by heat. It occurs by flame, boiling water or liquid, steam, sparks, chemicals, radiation, and electricity. Burn is classified as four grades depending on how deep into the skin a person is burned. As the deep second-degree burns possibly leave scars, it can have various physical, psychological, and aesthetical effects with seriousness on the patient with a burn. This report is on the 50-year-old female patient who had a burn with boiling water and a mixture condition of superficial and deep second degree burn. The Korean medical treatments such as Herbal acupuncture, Herbal medication, Acupuncture, Herbal-ointment were used for 17 days to treat effectively the patient with a mixture of superficial and deep second degree burn. It is difficult to find out the report that treats a burn with Korean medical treatment. If more clinical treatments as in this report are proved to be effective, we are able to expect that Korean medical treatment should be a good treatment in burn.

High-voltage electrical burn injuries on the scalp often result in scalp and cranial bone necrosis. Repetitive debridements and rich-vascularized flap coverage of the cranium are required. However, despite successful flap coverage, chronic osteomyelitis of cranial bones may occur. Treatment of chronic osteomyelitis of cranial bones is surgical debridement of the necrotic bone with re-coverage by a well-vascularized flap. The latissimus dorsi musculocutaneous flap is suitable not only for coverage of the cranium after the burn injury, but also for treatment of chronic osteomyelitis of the skull.

Staphylococcal toxic shock syndrome (TSS) is a severe systemic illness caused by toxins produced by Staphylococcus aureus. We report a case of staphylococcal TSS in a 16 month-old boy who presented with high fever, vomiting, skin rash, and shock after a burn injury. He was managed with intravenous vancomycin, fresh frozen plasma, and intravenous immunoglobulin. Methicillin-resistant S. aureus (MRSA) was isolated from the burn wound site and anterior nostril of the patient. In addition, the MRSA isolate was genetically characterized.
