Maxillofacial war injures is specific representative of severe hard and soft tissue defect. This type of injuries were different from the trauma because it may be fatal. The purpose of this study was to evaluate the injury type base on the retrograde medical record in the 104 patients from Feb. 1991 to Aug. 1992 in Korea Veterans Hospital. The obtained results were as follows. 1. Among 104 cases, 51 cases(49.0%) were classified as mandibular defects only, and 53 cases (51.0%) were classified as maxillary with mandibular defect (combined). 2. The etiologic factors of injury were gunshot, artillery and grenade or shell: 33 cases, 14cases, and 10 cases respectively in Korea War, 19 cases, 5 cases, and 8 cases respectively in Vietnam War. 3. In 57 cases of mandibular partial defect, the angle area showed the highest frequencies, 18 cases(31.6%). 4. In 42 cases of mandibular segmental defect, the area between the 1st molar and the ascending ramus showed the highest frequencies. 17 cases(40.4%), and almost all cases were unilateral defect (40 cases, 95.0%) 5. Reconstruction method performed for segmental mandibular defect were wire or plate(15 cases, 35.7%) and soft tissue closure only(12 cases, 28.7%), respectively.

Mesenteric injury occurs rarely in cases associated with blunt abdominal trauma. Despite its low incidence, mesenteric injury can lead to fatal outcomes such as hypovolemic shock due to hemoperitoneum or sepsis due to intestinal ischemia, or perforation-related peritonitis. For mesenteric injuries, especially those involving massive bleeding, intestinal ischemia, and perforation, the standard treatment is surgery. However, in the case of operative management, it should be borne in mind that there is a possibility of complications and mortality during and after surgery. The usefulness of transcatheter arterial embolization (TAE) is well known in solid organs but is controversial for mesenteric injury. We present a 75-year-old man with mesenteric injury due to blunt abdominal trauma. Initial abdominal computed tomography showed no hemoperitoneum, but a mesenteric contusion and pseudoaneurysm with a diameter of 17 mm were observed near the origin of the superior mesenteric artery. Since there were no findings requiring emergency surgery such as free air or intestinal ischemia, it was decided to perform nonoperative management with TAE using microcoils in hybrid emergency room system. TAE was performed successfully, and there were no complications such as bleeding, bowel ischemia, or delayed bowel perforation. He was discharged on the 23rd day after admission with percutaneous catheter drainage for drainage of mesenteric hematoma. The authors believe that treatment with TAE for highly selected elderly patients with mesenteric injuries has the positive aspect of minimally invasive management, considering the burden of general anesthesia and the various avoidable intraoperative and postoperative complications.

64세 남성이 2미터 높이에서 낙상한 이후 심한 우측 옆구리 통증으로 내원하였다. 시행한 조영증강 전산화단층촬영에서 우측 혈흉과 다수의 우측 갈비뼈 골절 및 우측 장골의 골절 소견이 있었다. 또한 간 주변에 혈종이 있었으나, 간실질 외상 소견은 보이지 않았다. 먼저 시행된 수술 중, 간문에서 지혈되지 않는 지속적인 출혈이 관찰되었다. 이에 대한 진단을 위해 인터벤션 시술이 시행되었고, 최초 간동맥조영술에서는 출혈 소견이 보이지 않았다. 이어서 시행한 조영증강 전산화단층촬영에서 좌측 복부의 조영제혈관바깥유출이 보였는데, 이는, 경피경간문맥조영술에서 좌측 문맥의 출혈로 확인되었다. 이 지점에 접착제 색전술을 시행했으나, 환자는 끝내 사망하였다. 이 증례를 통해 복부 외상환자 평가에서 간동맥조영술이 정상이라도 간문맥 손상의 가능성을 고려해야 한다는 것과 복부에서도 반충손상기전에 의한 손상이 가능하다는 것을 확인하였다.

As we become an aging society, the number of dementia patients increases every year (an estimated 10% of the elderly, equating to 1.27 million in 30 years). In addition, 17,000 cases of missing people with disabilities and dementia are reported annually, indicating that more than one person per hour goes missing. More than 50% of those who are lost suffer injuries (some of which are fatal) within 24 hours after going missing. This is why measures are urgently required to ensure safety of the elderly. The core function of the disappearances prevention system proposed by this research group is to identify and respond early to deviations of dementia patients from their homes or facilities by identifying the location of the occurrence of disappearance, so that real-time notifications occur when a they leave the protected area. In addition, multiple receivers and public transportation integrated terminals share information when a patient leaves and uses public transportation to ensure their safe return. Most existing beacon-based positioning service models have fixed signal transmitters and are serviced in the form of transport receivers, but the proposed service model has users wearing the BLE beacon and receivers fixed.

Fractures of frontal sinus account for 5%-12% of all fractures of facial skeleton. Inadequately treated frontal sinus injuries may result in malposition of sinus structures, as well as subsequent distortion of the overlying soft tissue. Such inappropriate treatment can result in aesthetic complaints (contour deformity) as well as medical complications (recurrent sinusitis, mucocele or mucopyocele, osteomyelitis of the frontal bone, meningitis, encephalitis, brain abscess or thrombosis of the cavernous sinus) with potentially fatal outcomes. Frontal contour deformity warrants surgical intervention. Although deformities should be corrected by the deficiency in tissue type, skin and soft tissue correction is considered better choice than bone surgery because of minimal invasiveness. Development of infection in the postoperative period requires all secondary operations to be delayed, pending the resolution of infectious symptoms. The anterior cranial fossa must be isolated from the nasal cavity to prevent infectious complications. Because most of the complications are related to infection, frontal sinus fractures require extensive surgical debridement and adequate restructuring of the anatomy. The authors suggest surgeons to be familiar with various methods of treatment available in the prevention and management of complications following frontal sinus fractures, which is helpful in making the proper decision for secondary frontal sinus fracture surgery.

Iatrogenic vascular injuries during lumbar disc surgery may occur rarely but they are serious complications, which can be fatal without appropriate management Prompt diagnosis and management of these complications are imperative to prevent a desperate outcome. A 72-year-Old female with proximal left common iliac artery iatrogenic injury during lumbar discectomy was successfully treated by percutaneous deployment of a stent graft in an emergency setting. Postprocedural angiogram demonstrated complete exclusion of the iliac artery laceration. The patient became hemodynamically stable. Two weeks later she complained of vascular claudication. Follow-up angiography revealed decreased arterial flow in the opposite common iliac artery. An additional kissing stent was inserted into the right common iliac artery and the symptoms of vascular claudication disappeared. Endovascular stenting offers a safe and effective method for the treatment of an iatrogenic arterial laceration, particularly in a critical condition. But, the contralateral iliac arterial flow should be kept intact in case of proximal iliac artery injury. Otherwise, additional treatments may be needed.

Acid ingestion can cause not only caustic injury on esophagus and stomach but also fatal outcome through systemic complications. We report the case of a patient who died early after severe caustic injury with strong acid. A 38-year-old man who ingested about 400ml of hydrochloric acid of unknown concentration was transferred to our hospital from a private clinic, in which he was managed with gastric irrigation through a nasogastric tube. He was complaining dyspnea and abdominal pain. Physical examination demonstrated tenderness and rebound tenderness on epigastric region. Severe metabolic acidosis and leukocytosis were noted. Radiological findings suggested perforation of gastrointestinal tract, although the physical signs were not typical. Endoscopy revealed caustic injuries of grade I on esophagus and of grade Ⅲ on stomach, which indicate more severe injury on the stomach than on the esophagus. Exploratory surgery was recommended but unfortunately not permitted by his family. Despite intensive measures, his vital signs deteriorated rapidly and he died 50 hours after the ingestion.

Hydrofluoric acid (HF), one of the strongest inorganic acids, is used mainly for industrial purpose. Hydrofluoric acid injuries has a potential for both systemic as well as severe local tissue destruction. One of the most serious consequences of severe exposure to HF by any route is marked lowering of serum calcium (hypocalcemia) and other metabolic changes, such as hypomagnesemia and which may result in a fatal outcome if not recognized and treated. promptly cardiotoxicity is not well known except arrhythmias, which are a primary cause of death. We report a case of myopericarditis by ingestion of hydrofluoric acid.

In this paper, the systematic problems of safety management in domestic construction industry are presented by the investigation and analysis of construction fatal injuries. In particular, it is discussed that the current construction safety management system by contractors leading is ineffective to prevent the serious accidents caused by inappropriate planning and design and to circulate the safety management cycle without interruption. A couple of ways for improving domestic construction safety management system are suggested in broad perspective. This is done by the analysis of construction safety management system of four advanced industrial countries such as the United States, the United Kingdom, Germany, and Japan and the study of a best practice. Total safety management system by owners leading is recommended to prevent construction accident effectively because this system makes all the parties join to the management system and distribute the responsibilities clearly to each party. This will drop the accident occurrence rate by dragging all the parties' cooperations and activating the total safety management system in an early stage.

Complete cricotracheal separation, which is the most severe type of laryngeal trauma, is an uncommonly seen injury that clinicians have limited experience in managing. However, it is potentially fatal. Due to limited exposure to this condition, mismanagement can occur, which may further aggravate the patient's condition. The most crucial part of managing this injury is to establish a secure airway. Tracheostomy under local anesthesia is the preferred method of airway stabilization, in order to avoid further injuries to the airway caused by endotracheal intubation. Here, we discuss the management of complete cricotracheal separation based on a case experienced in the east coast region of Malaysia, where this type of injury is rarely encountered.
