  • Objectives: The facial bones are the most noticeable area in the human body, and facial injuries can cause significant functional, aesthetic, and psychological complications. Continuous study of the patterns of facial bone fractures and changes in trends is helpful in the prevention and treatment of maxillofacial fractures. The purpose of the current clinico-statistical study is to investigate the pattern of facial fractures over a 4-year period. Materials and Methods: A retrospective analysis of 1,824 fracture sites was carried out in 1,284 patients admitted to SMG-SNU Boramae Medical Center for facial bone fracture from January 2010 to December 2013. We evaluated the distributions of age/gender/season, fracture site, cause of injury, duration from injury to treatment, hospitalization period, and postoperative complications. Results: The ratio of men to women was 3.2:1. Most fractures occurred in individuals aged between teens to 40s and were most prevalent at the middle and end of the month. Fractures occurred in the nasal bone (65.0%), orbital wall (29.2%), maxillary wall (15.3%), zygomatic arch (13.2%), zygomaticomaxillary complex (9.8%), mandibular symphysis (6.5%), mandibular angle (5.9%), mandibular condyle (4.9%), and mandibular body (1.9%). The most common etiologies were fall (32.5%) and assault (26.0%). The average duration of injury to treatment was 6 days, and the average hospitalization period was 5 days. Eighteen postoperative complications were observed in 17 patients, mainly infection and malocclusion in the mandible. Conclusion: This study reflects the tendency for trauma in the Seoul metropolitan region because it analyzes all facial fracture patients who visited our hospital regardless of the specific department. Distinctively, in this study, midfacial fractures had a much higher incidence than mandible fractures.

  • Background : The development of bronchoscopic equipment along with the precision of radiographic techniques had reduced the mortality rate of patients with tracheobronchial foreign bodies but has been no change in the incidence of tracheobronchial foreign bodies since their introduction. The aim of this study was to assess the clinical characteristics of a tracheobronchial foreign body aspiration and to evaluate the efficacy of the treatment modality in children and adults. Methods : This is a retrospective review of 64 patients who underwent bronchoscopic procedures for the treatment of aspirated foreign bodies from December 1994 through March 2004 at the Chonnam national university hospital. Results : There were 47 males and 17 females, aged from 1 month to 78 years. Most of the patients had no underlying illness except for one patient with a cerebrovascular accident that contributed to the foreign body aspiration. The most common symptom was cough, which was noted in 54 patients (84.3%). The other presenting symptoms were dyspnea (48.8%), fever (20.3%), sputum (14%), vomiting (7.8%), and chest pain (4.6%). Those whose tracheobronchial foreign bodies were diagnosed more than 2 days after the aspiration (21 patients) were more likely to have pneumonia than those whose foreign bodies were diagnosed within 2 days (p = 0.009). Foreign bodies were visualized in the plain chest radiographs in 12 cases (18.8%), while others showed air trapping (21, 32.8%), pneumonia (15, 23.4%), atelectasis (7, 10.9%), and normal findings (9, 14.1%). The foreign bodies were more frequently found in the right bronchial tree (36) compared with the left bronchial tree (22, p = 0.04). In order to remove the foreign bodies, twenty (31.2%) cases were removed using flexible bronchoscopy, while 42 (65.6%) and 2 (3.2%) cases required rigid bronchoscopy and surgery, respectively. Conclusions : Tracheobronchial Foreign body aspiration had a bimodal age distribution in the infancy and old age around 60 years. They were found more frequently in the right bronchial tree. In addition, patients whose foreign bodies were diagnosed more than 2 days after the aspiration were more likely have a infection. Rigid bronchoscopy is the procedure of choice for uncooperative children and for those with foreign bodies lodged deeply in the small bronchial tree.

  • Acute pancreatitis(AP) in children is not common but can be associated with severe morbidity rates and its diagnosis is often delayed. Thus, reported mortality rates range from 0 to 78%. We have treated 26 patients with AP from 5 to 17 years of age over the past 17 years. We are intended to assess the relevance of the prognostic criteria used to assess severity of adult AP and to review the etiology, clilical presentation, diagnosis, and management of AP in children. The authors retrospectively reviewed 26 children with AP managed in Kyung Hee University Hospital from 1978 to 1995. Among 26 patients with AP, male were 12, and female were 14. And the mean age of patients was 11.8 years. In 9(34.6%), no definitive cause was identified. Common causes of AP were trauma(23.1%) and biliary tract disease(23.1%). Other etiologies were viral infection(15.4%) and post ERCP(3.8%). The presenting features were abdominal pain(92.3%), vomiting(61.5%), fever(19.2%), submandibular pain(11.5%), and abdominal mass(7.6%). Back pain was rare(3.8%). Abdominal ultrasonographic findings were abnormal in 10 of 16 patients(62.5%) and abdominal CT findings were abnormal for 9 of 9 patients(100%). Seventeen patients(65.3%) were managed conservatively, and nine patients(34.6%) required surgical treatment. There was no mortality. To evaluate the severity of disease, we used the Imrie prognostic criteria used to assess the severity in adult AP. The number of positive criteria was correlated to the duration of hospitalization(r2=0.91) but statistically insignificant(p>0.05). But, the number of positive criteria was correlated to the operative incidence(r2=0.93) and statistically significant(p<0.05). The common causes of AP in children were unknown origin(34.6%), trauma(23.1%), and biliary tract disease(23.1%). Ultrasonography and computed tomography were useful imaging tools of AP in children. The Imrie criteria used to evaluate the severity in adult AP were suspected to be valuable to assess the severity of AP in children.

  • Background: Although the use of intravenous patient controlled analgesia (IVPCA) has been compared to the use of patient conrolled epidural analgesia (PCEA), there is no optimal administration route of alfentanil for the treatment of postoperative pain. This randomized double-blind study compared the efficacy of the use of IVPCA and PCEA for postoperative pain and the side effects after a total abdominal hysterectomy (TAH). Methods: Sixty patients undergoing a TAH were randomly assigned to receive either IVPCA (Group I) or PCEA (Group E) for the infusion of alfentanil for postoperative pain control. In both groups, a loading dose of $750{\mu}g$ alfentanil was administered. All patients received the same continuous infusion rate (0.3 mg/h), bolus dose (0.15 mg), and lockout time (15 min). The incidence of side effects, the VAS (visual analog scale) of pain, blood pressure, and heart rate were checked for 20 hours after the loading dose injection. Results: The VAS of pain was not significantly different between the two groups of patients. The onset of the analgesic effect was significantly more rapid in the Group I patients than in the Group E patients. There was no difference in side effects for either group. Conclusions: When considering multiple factors such as the onset of analgesia, technical difficulties or infection after the procedure, IVPCA using alfentanil is more useful than PCEA for postoperative pain control after a TAH.

  • Background: Recently, reverse total shoulder arthroplasty (RTSA) has been accepted as a main treatment option in irreparable massive rotator cuff tear with cuff arthropathy. The purpose of this study was to evaluate the early complication incidence and the preliminary clinical results of RTSAs performed in single institute. Methods: Fifty-seven RTSAs (56 patients) were performed between April 2011 and March 2013. The indications for RTSA were cuff tear arthropathy and irreparable massive rotator cuff tear with or without pseudoparalysis. Exclusion criteria were revision, preoperative infections and fractures. At final follow-up, 45 shoulders were enrolled. Mean follow-up duration was 12.5 months (range, 6-27 months). The mean age at the time of surgery was 73.6 years (range, 58-87 years). All the patients were functionally accessed via Constant score, American Shoulder and Elbow Surgeons (ASES) score, pain and functional visual analogue scale (VAS) scores and active range of motion. Complications were documented as major and minor. Major complications include fractures, infections, dislocations, nerve palsies, aseptic loosening of humeral or glenoid components, or glenoid screw problems. Minor complications include radiographic scapular notching, hematomas, heterotopic ossification, algodystrophy, intraoperative dislocations, intraoperative cement extravasation, or radiographic lucent lines of the glenoid. Results: The mean Constant score increased from 31.4 to 53.8 (p < 0.001). The pain and functional VAS scores improved (5.2 to 2.7, p < 0.001, 4.0 to 6.7, p < 0.001) and active forward flexion improved from $96.9^{\circ}$ to $125.6^{\circ}$ (p = 0.011). One or more complications occurred in 16 (35.6%) of 45 shoulders, with one failure (2.2%) resulting in the removal of implants by late infection. The single most common complication was scapular notching (9 [20%]). There were 4 (8.9%) axillary nerve palsies postoperatively (n=3: transient n. palsy, n=1: Symptom existed at 11 months postoperatively but improving). Conclusions: In a sort term follow-up, RTSA provided substantial gain in overall function. Most common early complications were scapular notching and postoperative neuropathy. Although overall early complication rate was as high as reported by several authors, most of the complications can be observable without compromise to patients' clinical outcome. Long term follow-up is required to clarify the clinical result and overall complication rate.

  • 인제대학교 의과대학 서울백병원 흉부외과학교실에서는 1987년 10월부터 1995년 12월까지 20세 이상의 성인 팔로사징후 9례에서 완전교정술을 시행하였다. 환자는 남자 5례, 여자 4례로 연령은 22세에서 42세까지였고 평균 29.6세였다. NYHA에 의한 기능적 분류는 Class II가 3례, Class III가 6례였고, 혈색소치는 10.8 ∼ 20.7 gm/㎗(평균 15.6 gm/㎗)였다. 술전임상 증상 및 징후는 청색증 8례, 운동시 호흡곤란 6례, 곤봉수지 5례, 잦은 상기도 감염 3례 였다. 폐동맥판 및 누두부협착이 모든 예에서 있었고, 2례에서는 좌측폐동맥에 발육부전이 있었다. 우심실유출로 협착에 대한 수술은 7례에서는 누두부절제술 및 판막절개술후 누두부에만 Goretex 첩포를 대어 확장술을 하였고, 2례에서는 누두부절제술과 판막절개술후 폐동맥 판막륜이 작아 이를 절개하여 주폐동맥까지 Goretex 첩포를 대어 확장하였다. 좌측 폐동맥에 발육부전이 있는 2례에서는 자가심낭편을 이용하여 폐동맥성형술을 하였다. 술후 사망환자는 없었고 합병증은 6례에서 발생하였는데 출혈이 가장 많아 5례에서 있었고 저심박출증 4례(44.4%)였다. 1례에서 일차수술 3개월후 잔존 심실중격결손과 삼첨판폐쇄부전이 있어 재수술을 하였다. 평균 추적관찰기간은 평균 25개월(범위, 11∼77개월)이었다. 술후 모든 환자는 NYHA class I이었다. 따라서 팔로사징후에서 나이가 들었다는 자체가 수술의 금기는 아니며, 성인 팔로사징후는 사망률도 낮으므로 완전교정이 가능하다고 사료된다.

  • Purpose: Recently, trauma is more frequent due to the increases in the population, the number of traffic accident, and the incidence of violence. Especially, abdominal trauma is a leading cause of morbidity and mortality. We analyzed the clinical features and the factors associated with morbidity and mortality. Methods: We analyzed 136 patients of abdominal trauma who were admitted at the Department of Surgery, Chonnam National University Hospital, from January 2003 to June 2005. We analyzed the cause of trauma, the injured organ, combined injuries, mental status, blood pressure, laboratory findings, morbidity, and mortality. The relationships between by variable were assesed by using the independent samples test and the Kruskal?Wallis test. Results: The causes of trauma were traffic accidents (98 cases, 72%), falling accidents (9 cases, 6.6%), violence (6 cases, 4.4%), and stab injuries (6 cases, 4.4%). The injured organs were the small intestines (47 cases, 34.6%), the liver (35 cases, 25.7%), the spleen (26 cases, 19.1%), the mesentery (17 cases, 12.5%), the large intestines (15 cases, 11.0%), the pancreas (14 cases, 10.3%), etc. The most common combined injury was chest injury (53 cases, 39%). Comatose or semicomatose mental status and shock on admission (<60 mmHg in systolic) were related to high mortality (85.7%). In laboratory findings, decreased hemoglobin (<8 g/dL), and platelet count (<$50,000/mm^3$), and increased creatinine level (>1.6 mg/dL) were significant prognostic factors. The incidence of postoperative complications was 40.4%, and frequent complications were wound infection (8.1%) and re-bleeding (8.1%). The overall mortality rate was 18.4%, and most common cause was hypovolemic shock (18 cases, 13.2%), however, there was no statistical difference according to injurd organ. Conclusion: In the multivariate analysis, mental status, hemoglobin, and serum creatinine level were the most significant prognostic factors. When an abdominal trauma patient arrives at the emergency room, a rapid and accurate evaluation of the patient's status and risk factors, and resuscitation, if necessary, have to be performed to lower the morbidity and mortality.

  • 본 연구는 개에서 심장사상충을 검출하기 위하여 표준검사를 적용하지 않은 상황에서 중합연쇄반응검사 (PCR)의 진단 능력을 평가하였다. 효소면역검사법 (ELISA)과 PCR 검사를 동시에 사용한 경우 PCR 검사의 민감도와 특이도는 두 검사의 조건부 독립을 가정한 상태에서expectation-maximization (EM) 알고리즘을 이용한 최대우도법과 Bayesian 기법으로 두 집단 검사 모형으로 분석하였다 2002-2004년 기간 중 심장사상충검사 결과를 기록한 의무기록에서 무작위로 266개 결과를 추출하여 133개씩 2회의 시험으로 배치하였다. 2회의 분석결과를 종합할 때 EM 알고리즘에서 PCR 검사의 민감도와 특이도는 각각 96.4-96.7%와 97.6-98.8%, Bayesian기법에서는 94.4-94.8h와 97.1-98%로 추정되었다. PCR 검사는 심장사상충을 스크리닝하는 도구로 유용하며, 표준검사를 적용하지 않은 상황에서 진단검사의 특성을 추론하는 방법으로 Bayesian 기법은 매우 유용함을 확인하였다.

  • 황색포도상구균은 사람에게서 염증을 동반한 다양한 형태의 국소적 또는 전신적 감염을 일으키는 주요 병원균이며, 황색포도상구균에서 풍부하게 발현되는 Staphylococcal protein A (SPA)는 염증의 활성화나 면역 반응의 회피와 관련된 균력인자로서 작용할 수 있다. 본 연구에서는 사람의 HaCaT 피부상피세포에서 재조합 SPA 단백질을 이용하여 염증반응에 대한 효과를 조사하기 위해서 pET-28a 발현벡터시스템을 이용하여 성공적으로 재조합 SPA 단백질을 제작하였고, 이 단백질(2 ${\mu}g$/ml)을 6, 12 및 24시간 처리한 HaCaT 피부상피세포에서 RT-PCR 및 ELISA를 이용하여 염증관련 부착인자 및 사이토카인의 발현을 분석하였다. SPA 처리 후 6시간에서 24시간까지 E-selectin, ICAM-1, MCP-1, IL-6 및 IL-8의 발현이 현저하게 증가함을 확인하였다. 또한 SPA는 HaCaT 피부상피세포에 대한 U937 단핵구의 부착력을 증진시켰다. 따라서, 본 연구의 결과는 SPA가 HaCaT 피부상피세포의 염증반응을 촉진시킨다는 사실을 보여주었으며, 황색포도상구균에 의한 피부염증질환에 있어서 중요한 병원성인자로서의 역할을 수행한다는 사실을 시사해준다.
