This is a retrospective clinical study on 2,955 patients who had visited the Emergency Room of Sang-gye Paik Hospital and then been treated in the Department of Oral and Maxillofacial Surgery during recent 4 years from Aug. 2002 to Dec. 2006. The obtained results were as follows. The total number of patients was 2,955 and the ratio of male to female was 1.72:1. The age distribution peak was the 1st decade (30.8%), followed by the 3rd decade (14.3%) and the 4th decade (14.0%). Trauma (62.3%) was the most frequent cause in dental emergency patients, pulpitis (13.0%) and infection patients were next in order of frequency. In trauma patients group, facial bone injury, tooth injury, soft tissue injury were included and soft tissue injury group was most prevalent, followed by tooth injury group and facial bone group. In total patient, the ratio of admission was 3.5%. We obtained the results of the distribution of primary emergency care in the traumatic injury, causal distribution of the jaw fracture, distribution of related medical department in multiple associated injuries, distribution of emergency care in infection, causal distribution and control methods of oral bleeding, distribution of TMJ disorder. The trauma patient group was major in the dental patients who had visited the emergency room, but other various groups were included. So we should analyze the pattern and the variation of the dental emergent patient to provide the proper treatment.

배경: 흉부 외상 환자에 있어서 폐렴은 가장 흔한 감염증이며, 진단 및 치료의 발전에도 불구하고 이환율과 치사율을 높이는 매우 심각한 합병증이다. 본 연구는 흉부 외상 환자 중 인공호흡기 치료를 하였던 환자에서 폐렴의 임상 양상을 분석하고 그 원인 인자를 파악하고자 하였다. 대상 및 방법: 2001년 1월부터 2006년 12월까지 흉부 외상에 의해 인공호흡기 치료를 시행한 78명의 환자를 대상으로 하였다. 대상 환자 중 폐렴이 발생한 38예를 I군으로,폐렴이 발생하지 않은 40예를 II군으로 나누어 비교 분석하였다. 각 군의 병원 도착시 혈역학적 소견 및 이학적 소견, 혈액학적 소견, 외상의 원인, 흉부 외상의 형태 및 그 정도, 동반 외상, 기저 질환, 인공호흡기 이용 기간, 중환자실 입원 기간 그리고 사망률 등을 후향적으로 조사하였다. 결과: 대상 환자는 남자 57명, 여자 21명이었으며, 평균 연령은 $48.3{\pm}19.9$세였다. 흉부외상에 의해 인공호흡기 치료를 시행한 환자의 48.7%에서 외상 후 페렴이 발생하였고, 사망률은 I군에서 21.0%, II군에서 2.5%로 II군에서 현저하게 높았다. 내원시 혈역학적 소견 상 수축기 혈압이 90 mmHg 이하의 쇼크 상태로 인해 수축촉진약(inotropics)을 사용한 경우는 I군에서 24예(63.1)로 II군의 10예(25%)보다 유의하게 많았으며(p=0.001), C-Reactive Protein(CRP) 치는 I군에서 $11.3{\pm}7.8$으로 II군의 $6.4{\pm}7.3$에 비해 유의하게 높았다(p=0.006). 인공호흡기 이용기간 및 중환자실 입원 기간은 I군에서 각각 17.4일, 21.7일로 II군의 6.5일, 9.7일에 비해 유의하게 길었다(p<0.001). 결론: 외상 후 폐렴의 발생은 인공호흡기 이용 기간 및 중환자실 입원 기간이 긴 환자에서 많이 발생하였으며 그외 내원시 측정한 CRP 치가 높은 경우, 쇼크 상태로 인해 수축촉진약(inotropics)를 사용한 경우에 많이 발생하였다. 흉부 외상 환자의 치료 시 이런 요인들을 고려한다면 폐렴의 예방 및 치료에 도움이 될 것으로 생각된다.

Purpose: We present our experience about the clinical aspect and treatment modalities of ostechondritis dissecans of the talus. Material and Method: This study included 35 patients, 38 cases diagnosed as ostechondritis dissecans of the talus that were proved by clinical and radiologic finding. The methods of treatment were conservative (2 cases), multiple drilling (1 case), excision (1 case), excision, curettage & multiple drilling (23 cases), curettage & bone peg fixation (2 cases), curettage & bone graft (2 cases), and autogenous osteochondral transfer(Mosaicplasty) (7 cases). Results: Of the 38 cases, 30 cases were associated with a history of trauma (17 cases of medial lesion, 13 cases of lateral lesion), and 9 cases of which had major trauma history and 21 cases, minor repetitive trauma history. According to O'Farrel grading system, 21 cases (55%) had good results, 11 cases (29%) had fair results, and 6 cases (16%) had poor results. Of the medial lesion 16 cases had good results, 6 cases, fair results, and 2 cases, poor results. Of the lateral lesion 5 cases had good results, 5 cases, fair results, and 4 cases, poor results. Conclusion: There were fair or good results in 84% of patients with surgical treatment. Curettage and multiple drilling reveals a good result in medial lesion in grade I, II, III and lateral lesion in grade I, II. Autogenous osteochondral transfer(Mosaicplasty) is considered for the cases in grade III, IV(medial and lateral), lesion exceeds 1Cm of size and poor result with another treatment modality.

Hepatic compartment syndrome (HCS) is a rare but life-threatening entity that consists of a decreased portal flow due to intraparenchymal hypertension secondary to subcapsular liver hematoma. Lethal liver failure can be observed. We report three cases, and review the literature. A 54-year-old male was admitted for extensive hepatic subcapsular hematoma after blunt abdominal trauma. Initially, he underwent embolization of the hepatic artery's right branch, after which he presented clinical deterioration, major cytolysis (310 times the upper limit of normal [ULN]), and liver failure with a prothrombin time (PT) at 31.0%. A 56-year-old male underwent liver transplantation for acute alcoholic hepatitis. On postoperative day 2, he presented a hemorrhagic shock associated with deterioration of liver function (cytolysis 21 ULN, PT 39.0%) due to extensive hepatic subcapsular hematoma. A 59-year-old male presented a hepatic subcapsular hematoma five days after a cholecystectomy, revealed by abdominal pain with liver dysfunction (cytolysis 10 ULN, PT 63.0%). All patients ultimately underwent urgent surgery for liver capsule excision, hematoma evacuation, and liver packing, if needed. The international literature was screened for this entity. These three patients' outcomes were favorable, and all were alive at postoperative day 90. The literature review found 15 reported cases. HCS can occur after any direct or indirect liver trauma. Surgical decompression is the main treatment, and there is probably no place for arterial embolization, which may increase the risk of liver necrosis. A 13.3% mortality rate is reported. HCS is a rare complication of subcapsular liver hematoma that compresses the liver parenchyma, and leads to liver failure. Urgent surgical decompression is needed.

The trauma has been known as a major etiologic factor in temporomadibular joint disorders. The endotracheal intubation is suspected as one of the traumatic factor to temporomandibular disorder. But there are few reports about the amount of mouth opening during endotracheal intubation and temporomandibular joint disorder after endotracheal intubation. The authors studied the effects of endotracheal intubation to temporomandibular joint with 70 patients given surgical operation through general anesthesia. The results were as follows. 1. The mean amount of mouth opening for entire patients during endotracheal intubation was 26.3mm (s, d : 2.6), for oral intubation group 25.9mm(s, d : 3.2), for nasal intubation group 26.6mm(s, d : 1.9). There was no difference between two group stastically. (p<0.05) 2. 1 week later endotracheal intubation, the maximum mouth opening increased 1.5mm for entire patients, 1.5mm for oral intubation group, 1.6mm for nasal intubation group than behare endotracheal intubation. 3. Five patients complained the discomforts around temporomandibular joint after endotracheal intubation. The amount of mouth opening during endotracheal intubation was within physiologic range. It seemed that $45^{\circ}$ upward endoscopic lifting for exposure of glottis gave trauma to temporomandibular joint.

Psychogenic nonepileptic seizures (PNES) is a neuropsychiatric condition that causes a transient alteration of consciousness and loss of self-control. PNES, which occur in vulnerable individuals who often have experienced trauma and are precipitated by overwhelming circumstances, are a body's expression of a distressed mind, a cry for help. PNES are misunderstood, mistreated, under-recognized, and underdiagnosed. The mind-body dichotomy, an artificial divide between physical and mental health and brain disorders into neurology and psychiatry, contributes to undue delays in the diagnosis and treatment of PNES. One of the major barriers in the effective diagnosis and treatment of PNES is the dissonance caused by different illness perceptions between patients and providers. While patients are bewildered by their experiences of disabling attacks beyond their control or comprehension, providers consider PNES trivial because they are not epileptic seizures and are caused by psychological stress. The belief that patients with PNES are feigning or controlling their symptoms leads to negative attitudes of healthcare providers, which in turn lead to a failure to provide the support and respect that patients with PNES so desperately need and deserve. A biopsychosocial perspective and better understanding of the neurobiology of PNES may help bridge this great divide between brain and behavior and improve our interaction with patients, thereby improving prognosis. Knowledge of dysregulated stress hormones, autonomic nervous system dysfunction, and altered brain connectivity in PNES will better prepare providers to communicate with patients how intangible emotional stressors could cause tangible involuntary movements and altered awareness.

Purpose: A tube thoracostomy is an invasive procedure that places patients at risk for complications. Tube thoracostomies are frequently performed by emergency medicine residents. Thus, the purpose of the study was to assess both the complication rate for tube thoracostomies performed by emergency medicine residents and the factors associated with these complications. Methods: A retrospective chart review of all patients who had undergone a tube thoracostomy performed by emergency medicine residents between January 2008 and February 2009 was conducted at a university hospital. Complications were divided into major and minor complications and into immediate and delayed complications. Complications requiring corrective surgical intervention, requiring the administration of blood products, or involving situations requiring intravenous antibiotics were defined as major. Complications that were detected within 2 hours were defined as immediate. Results: Tube thoracostomies were performed in 189 patients, and 70 patients(37%) experienced some complications. Most complications were immediate and minor. In multiple logistic regressions, BMI, hypotension and resident seniority were significantly associated with complications. Conclusion: The prevalence of complications was similar to these in previous reports on the complications of a tube thoracostomy. Most complications from tube thoracostomies performed by emergency medicine residents were immediate and minor complications. Thus, emergency medicine residents should be allowed to perform closed tube thoracostomies instead of thoracic surgeons.

Purpose: We aimed to provide effective emergency medical services (EMS) response strategies for coping with high acuity patients during the pandemic by analyzing the influence of the COVID-19 and social distancing on EMS. Methods: In this retrospective observational study, we analyzed the distribution of high acuity patients transported by Daejeon 1-1-9 EMS during the COVID-19 pandemic period, between February 1, 2020 and October 31, 2020 and the same period in 2019, as well as the level 3 social distancing enforced period, between July 27, 2020 and October 31, 2020. Results: The EMS dispatches decreased by 17% during the observed COVID-19 pandemic period compared to the same period in 2019. The number of cases with cardiac arrest and positive prehospital stroke scale rose by (p<.001). Patients with cardiac arrest, trauma, and positive prehospital stroke scale increased by during the level 3 social distancing period. Conclusion: Unlike the decreased EMS call volume and patient transports during the COVID-19 pandemic, cardiac arrest cases and the severity of high acuity patients tended to increase. We suggest that EMS systems should contrive a response strategy considering the collateral effect of major epidemics on the incidence rate of high acuity patients.

This study evaluated retrospectively the treatment method and postoperative complications of communited mandibular fractures. We analyzed the clinical and radiologic data of 14 patients with the comminuted mandibular fractures who were admitted to Chosun University Dental Hospital from January 1998 to December 2003. We reviewed the cause of trauma, fracture sites, treatment methods, and postoperative complications. Thirteen patients (93%) had a successful treatment outcome without complications. Only one patient developed postoperative osteomyelitis requiring early plate removal and sequestrectomy. For the comminuted fractures of mandible, internal fixation using micro- or mini-plate was an effective treatment method with a low incidence of major complications.
