Acute mesenteric infarction is a catastrophic illness representing a diverse spectrum of pathologic conditions which ultimately lead to necrosis of the intestine and which is uniformly fatal if left untreated. Despite better understanding of the disease process, acute mesenteric infarction continues to be a lethal disorder with high mortality rate. We experienced two cases of acute mesenteric infarction due to superior mesenteric arterial and venous branch occlusion, respectively, in recent years: One case was focal segmental ischemia with normal radiologic finding including angiography, successfully treated with segmental resection of the necrotized ileum, another case was mesenteric venous thrombosis, also treated with resection of necrotized small intestine followed by second look operation.

PURPOSE: Epidemiologic data on emergency department (ED) patients with systemic inflammatory response syndrome (SIRS) are limited. We examined the prevalence, risk factors, etiologies and outcomes for the various forms of the SIRS, as well as their relationships with infection in ED. METHODS: The subjects were 16,718 non-trauma adult patients who visited a 900- bed university hospital ED between November 2006 and October 2007. ED records were reviewed, and all patients meeting the criteria for SIRS were enrolled retrospectively. SIRS patients were further subdivided into four groups (non-infectious SIRS, sepsis, severe sepsis, septic shock). Baseline characteristics, ED dispositions, and prognoses of patients in each group were analyzed. RESULTS: Among 16,718 patients, there were 2,790 SIRS patients (16.7%). The SIRS patient group was composed of 1,546 non-infectious SIRS patients (55.4%), 1,078 sepsis patients (38.6%), 119 severe sepsis patients (4.3%), and 47 septic shock patients (1.7%). ED patients with SIRS were older on average than non-SIRS patients (52 versus 48, p<0.001). The most common sources of SIRS was the gastrointestinal system (28.3%), followed by the respiratory system (22.9%) and the genitourinary system (11.8%). Pneumonia (18.9%) was the single most common cause of infectious SIRS. The admission rate was higher for SIRS patients than for non-SIRS patients (44% versus 21%). The 28-day mortality rate for non-infectious SIRS, sepsis, severe sepsis, and septic shock patients were 4.5%, 1.3%, 25.2%, and 63.8%. Sepsis severity was correlated with increased rates of both hospital admission and mortality (p<0.001). CONCLUSION: 55% of SIRS patients who visited the ED had a non-infectious cause. SIRS patients were older than non-SIRS patients, and hospital and ICU admission rates were also higher. Sepsis severity was correlated with older age, increased hospital admission rate, increased ICU admission rate, and increased mortality rate.

PURPOSE: Atypical ductal hyperplasia (ADH) is a lesion with significant malignant potential We evaluated the prevalence of breast carcinoma in surgical breast biopsies performed on palpable breast lesions diagnosed initially as ADH by fine needle aspiration cytology (FNAC). MATERIALS AND METHODS: Between January 1, 1996 and December 31, 1997, 942 patients who underwent FNAC at the Department of Surgery and Pathology, College of Medicine, Hallym University and Department of Surgery, Central Gil Hospital were analyzed. ADH was found in 46 (4.9%) of 942 patients, and surgica1 excision subsequently was performed in 39 of these cases. In these 39 cases, cytologic and histopathologic results from FNAC and surgical biopsies were reviewed and correlated. RESULTS: Histopathologic study of the 39 surgically excised lesions diagnosed as ADH in their FNAC specimens showed breast cancer in 15 cases (38.5%), ADH in 11 cases (28.2%) and benign disease in 13 cases (33.3%). CONCLUSION: In our patient populatian, 15 cases (38.5%) of 39 patients with ADH at FNAC had a breast cancer. Therefore, the FNAC finding of ADH may warrant a recommendation for an excisional biopsy.

Eagle's syndrome is a disease caused by an elongated styloid process or calcified stylohyoid ligament. Eagle defined the disorder in 1937 by describing clinical findings related to an elongated styloid process, which is one of the numerous causes of pain in the craniofacial and cervical region. The prevalence of individuals with this anatomic abnormality in the adult population is estimated to be 4% with 0.16% of these individuals reported to be symptomatic. Eagle's syndrome is usually characterized by neck, throat, or ear pain; pharyngeal foreign body sensation; dysphagia; pain upon head movement; and headache. The diagnosis of Eagle's syndrome must be made in association with data from the clinical history, physical examination, and imaging studies. Patients with increased symptom severity require surgical excision of the styloid process, which can be performed through an intraoral or an extraoral approach. Here, we report a rare case of stylohyoid ligament bilaterally elongated to more than 60 mm in a 51-year-old female. We did a surgery by extraoral approach and patient's symptom was improved.

OBJECTIVES: The purpose of this article is to analyze the incidence, demographic distribution, type, and etiology of mandible fractures that were treated by the Department of Oral and Maxillofacial Surgery in Kyung Hee University Dental Hospital from January 2002 to December 2012. MATERIALS AND METHODS: This was a descriptive and analytic retrospective study that evaluated 735 patients that were treated for mandible fracture. RESULTS: This study included 1,172 fractures in 735 patients. The ratio of male to female patients was 5.45 : 1; the maximum value was in patients between 20 and 29 years (38.1%) and the minimum in patients over 70 years old. The monthly distribution of facial fractures peaked in the fall and was lower during winter. No specific correlation was identified based on the annual fracture distribution. Among the 735 fracture patients, 1.59 fracture lines were observed per patient. The most frequent site was the symphysis, which accounted for a total of 431 fractures, followed by the angle (348), condyle (279), and body (95). The symphysis with angle was the most common site identified in combination with fracture and accounted for 22.4%, followed by symphysis with condyle (19.8%). The angle was the most frequent site of single fractures (20.8%). The major cause of injury was accidental trauma (43.4%), which was followed by other causes such as violence (33.9%), sports-related accidents (10.5%), and traffic accidents (10.1%). Fracture incidents correlated with alcohol consumption were reported between 10.0%-26.9% annually. CONCLUSION: Although mandible fracture pattern is similar to the previous researches, there is some changes in the etiologic factors.

The infectious complications after renal transplantation remain as an important causes of both mortality and graft loss. The lung is the most common target for post-transplant infection. We analyzed the causative agents, treatments and outcomes of post-transplant pulmonary infections. From 1990 to 1998, 192 renal allografts were performed at Hallym University Hospital. Seven cases (3.6%) of 5 males and 2 females developed serious pulmonary infections and required hospitalization. The mean age was 42.6 years. The onsets of pulmonary infections were from a month to 6 months in 3 cases, from 6 months to a year in one case and after a year in 3 cases. Triple therapy regimen was used in 4 cases as an immunosuppression therapy. Acute rejections developed in 6 cases. Causative organisms were Cytomegalovirus in 2 cases, Mycobacteria in 2 cases, Aspergillus in a case, Nocardia in a case and unknown in a case. Despite appropriate antibiotics, four patients did not respond to the treatment and died. The early recognition of infection and appropriate therapy is important to reduce fatal consequence.

Renal transplantation has been adopted as the treatment of choices for most patients with a end stage renal disease. This is the presentation of our experience of renal transplantation at Hallym University Hospital. From March 1984 to July 1998, 207 cases of renal transplantations were performed, 15 cases out of which were lost during follow-up period and excluded from the study. The mean age of recipients was 37.1 years. The male to female ratio was 1.5:1. Eighty nine renal allografts (46.4%) were from living unrelated donors, 59 (30.7%) from living donors and 44 (22.9%) from cadaveric donors. As an immunosuppression theray, a triple regimen was used in 104 cases (54.2), a double regimen in 86 (44.8%) and a single regimen in one (0.5%). The overall rejection developed in 87 cases (45.3%). The rejection rate was 59.3% in renal allografts from living related donors, 37.1% from living unrelated donors and 43.2% from cadavaric donors. The OKT3 and the antilymphocyte globulin (ALG) were used for steroid resistent rejection in 8 and 2 cases, respectively. Post-transplant diabetes mellitus were noticed in 22 cases (11.5). The most common complication was infection (28.1%), and 11 recipeints (5.7%) died during follw-up period. Infection was the leading cause of mortality. The overall graft survival was 92.2% at 1 year span and 83.1% at 3 year span. The overall patient survival was 95.6% at 1 year span and 92.5% at 3 year span.
