Purpose: This study aimed to evaluate the thermal protective function of firefighter clothes and gloves through real scale fire simulations. Methods: Firstly, the fire simulation by real scale flame was performed for firefighter clothes. A manikin equipped with firefighter clothes was directly exposed to flames which energy average is 84 Kw/m². for 22 seconds. Heat flux gauges attached on the body measured surface temperature elevation. Secondly, we also performed the other fire simulation by hot plate exposure to firefighter gloves. Firefighter gloves with heat flux gauges exposed hot plate which temperature is 300℃ in both dry and moist conditions. Primary outcome was surface temperature change of manikin body (first simulation) and hand (second simulation) over times. Results: In the first flame simulation, the surface temperature of face and shoulders elevated more rapidly comparing with the other body surface area when initial period of flame shutter open. After 18sec of shutter open, the surface temperature of upper trunk elevated rapildy. After shutter closure, high surface temperature kept continuously on right side of face and left shoulder. In the second hot plate simulation, fingers and palms showed higher surface temperature than the other areas of hands in the both dry and wet conditions. Conclusion: This study suggests that the real scale flame enables firefighter clothes to lose their heat protective function suddenly after 18 seconds. Additionally, the protective function of firefighter gloves were relatively weaker in the palmar side of fingers than the other parts of hand. There should be additional study for evaluate thermal protection performance of firefighter clothes. And, further effort for reinforce palmar side of fingers of firefighter gloves should be done.

A 46-year-old male with alcoholic liver cirrhosis underwent a transjugular intrahepatic portosystemic shunt (TIPS) for refractory ascites. On the 9th day after the procedure, he presented with melena and decreasing hemoglobin levels. Hemobilia due to fistula formation between the right intrahepatic bile duct and right hepatic artery was suspected on computed tomography. Angiography revealed a fistula of the small branches of the hepatic segmental arteries, and right intrahepatic bile duct was confirmed; embolization was successfully performed with a coil for the eighth segmental hepatic artery, a glue-lipiodol mixture for the fifth segmental hepatic artery, and gelfoam slurry for the right anterior hepatic artery. However, 2 days after embolization, the patient died owing to aggravated disseminated intravascular coagulopathy. When gastrointestinal bleeding occurs after TIPS, careful evaluation is immediately required, and hemobilia should be considered.

Free flap surgery is commonly used for extensive facial burn. However, free flap surgery requires long operation time and difficult technique. Also, it requires further procedure to prepare the recipient vessels. Hence, applying pedicle flap surgery instead of free flap surgery is effective for patients with facial burn. Among a wide range of pedicle flaps, we performed lower trapezius myocutaneous pedicle flap to patients with third degree facial burn and got satisfactory results without complications. Lower trapezius myocutaneous pedicle flap has a wide arc of rotation so that it can cover middle and lower part of the face. Furthermore, it is thinner than other myocutaneous pedicle flap that can be used for facial reconstruction. Due to these advantages, lower trapezius myocutaneous pedicle can be an attractive option for the reconstruction of facial burn.

Postburn scar contracture of sole can cause musculoskeletal deformity, restricted range of motion, and decreased quality of life. It is very important to exhibit similar characteristics of the sole when reconstructing the sole because it has to resist shearing force and weight bearing. In this case, we performed medialis pedis free flap for the postburn scar contracture of the sole and the flap survived without complication. The patient satisfied with functional and aesthetic outcomes. Medialis pedis free flap, which is harvested adjacent to the sole, can show similar characteristic of the sole and maintain adequate contour. Moreover, this flap can be harvested without sacrifice of major vessel or nerve. Due to these advantages, medialis pedis free flap can be an ideal option for the reconstruction of the sole.

Extrauterine adenomyoma of the liver is extremely rare. Only a few cases have been reported, and these reports have focused mainly on histopathology. Herein, we report the specific imaging findings of extrauterine adenomyoma of the liver in a 43-year-old woman with epigastric pain, which was initially diagnosed as a hepatic adenoma. CT and MRI revealed a solid and cystic mass with hemorrhagic foci and weak persistent enhancement, located in the subcapsular region of the right hepatic lobe.

Bronchogenic cysts are rare congenital anomalies that are most frequently found in the mediastinum along the tracheobronchial tree, especially in the posterior aspect of the superior mediastinum. Bronchogenic cysts have also been reported in intrapulmonary, intrapericardial, abdominal, and retroperitoneal locations. Herein, we report a case of a retroperitoneal bronchogenic cyst in the presacral space. The patient was diagnosed based on a post-operative histopathological examination.

Coronavirus disease 2019 (COVID-19) is spreading rapidly around the world. Several articles have so far reported on radiological findings of COVID-19 pneumonia. Herein, we present three cases of COVID-19 pneumonia in South Korea, and provide clinical information as well as chest radiograph and chest CT findings.

Pulmonary adenofibroma is a rare tumor, with a few reported cases in the literature. Radiologically, the lesion appears as a solitary pulmonary nodule in most cases, and the multiplicity of this disease entity is extremely rare. We present an unusual case of pulmonary adenofibroma in a 71-year-old woman manifested as two nodules in different lobes of the lung on CT. Histopathological and immunohistochemical examinations are needed to establish the definitive diagnosis of pulmonary adenofibroma.

Renal artery injury is a rare complication in blunt trauma, but can cause devascularization of the kidney, leading to renal failure. It requires early diagnosis and management. The treatment of renal artery injury still remains controversial, but recent studies have reported the successful treatment outcome with endovascular stent placement. Nevertheless, there is no standard treatment strategy in cases of pediatric patients. We report a case of a 16-year-old girl with right renal artery occlusion associated with a grade IV liver laceration. She was treated with only balloon angioplasty, and the kidney showed marked improvement of parenchymal perfusion with normalized renal function. Treatment with only balloon angioplasty can be a treatment option in pediatric patients with renal artery injury.

Acute disseminated encephalomyelitis (ADEM) and Guillain-$Barr{\acute{e}}$ syndrome (GBS) are both rare post-infectious neurological disorders. The co-existence of these conditions has often been reported despite of low incidence. We describe a 20-year-old male, who presented with acute flaccid paralysis and encephalopathy. The patient showed reversible MRI lesions suggesting ADEM. This case showed anti-GT1a IgG and anti-GM1 IgM antibodies positivity. We suggest that certain immunogenicity within central and peripheral nervous system may share a common autoimmune process during the disease course.
