The changes of serum glutamic oxaloacetic transaminase [SGOT], serum glutamic pyruvic transaminase [SGPT], serum lactic dehydrogenase [LDH] and serum creatine phosphokinase [CPK] were examined during and after the open heart surgery. In the total of 52 patients with heart diseases including 40 cases of congenital heart anomalies and 12 cases of acquired valvular heart diseases who undergone open heart surgery under cardiopulmonary bypass. The results obtained are as follows: 1. The average value of SGOT before surgery was 30.27 [ 18:86 units. The enzyme was reached to the maximum of 139.88 [ 89.43 units on the 1st day after the operation [p< 0.05], the enzyme activity was gradually decreased from the 3rd day after the operation, returned to the normal range on the 7th day after the operation. 2. The average value of SGPT before surgery was 14.36 [ 7.45 units. The enzyme was reached to the maximum of 34.67 [ 27.64 units on the 2nd day after the operation, but it was valueless statistically, the enzyme activity was gradually decreased from the 3rd day after the operation, returned to the normal range on the 5th day after the operation. 3. The average value of LDH before surgery was 263.07 * 86.66 units. The enzyme was reached to the maximum of 662.29 * 303.60 units on the 2nd day after the operation [p < 0.05], the enzyme activity was gradually decreased from the 5th day after the operation, returned to the normal range on the 7th day after the operation. 4. The average value of CPK before surgery was 141.35 * 43.44 units. The enzyme was reached to the maximum of 377.42 [ 222.02 units on the 1st day after the operation [p < 0.05], the enzyme activity was gradually decreased from the 5th day after the operation, returned to the normal range on the 7th day after the operation. 5. In the relationships of the serum enzymes and duration of the extracorporeal circulation, the values on the group over 90 minute of the extracorporeal circulation were increased than on the group below 90 minute of the extracorporeal circulation, but it was valueless statistically.

In the early days of open heart surgery, acute respiratory failure following extracorporeal circulation was a significant deterrent to an uncomplicated recovery. Although a marked improvement in prevention and treatment of postoperative respiratory failure has been achieved, the problem has not been completely eliminated and continues to be a causative factor in morbidity and mortality Fates following open heart surgery. We have attempted to evaluate postoperative respiratory failure in patients undergoing cardiac operation with the aid of extracorporeal circulation. Our series comprised 92 patients who underwent elective open heart surgery at the Department of Thoracic and Cariodvascular Surgery, School of Medicine, Kyungpook National University, from January, 1980 to December, 1982. In our study, the overall incidence of acute respiratory failure following open heart surgery was 18.8 percent. The duration of extracorporeal circulation in a series of 18 patients who developed postoperative respiratory failure [Group B] was longer in the mean value [120.3 minutes] than the uncomplicated 74 patients [Group A] [85.8 minutes]. The duration of artificial ventilation after open heart surgery in Group A averaged 13.4 hours as contrasted with 76.5 hours in Group B. In Group B, the inspired oxygen concentration [FiO2] in artificial ventilation was continued in the higher level than Group A until 18 hours after operation. Upon pulmonary function test performed pre-and postoperatively, residual volume[RV], RV/TLC and FEV 1.0/FVC were remained essentially unchanged following extracorporeal circulation, whereas forced vital capacity [FVC], FEV 1.0 and FEF 25-75% were significantly decreased in the early postoperative days. The incidence of acute respiratory failure was significantly higher in a series of patients who developed postoperative complications, such as re- exploration due to massive bleeding, low cardiac output, acute renal failure and arrhythmias. A total of 9 patients died, giving an overall mortality was 33.3 percent whereas the mortality was only 1.1 percent for patients without respiratory failure.

Objective. The objective of this international comparative study was to investigate the clinical features and outcome of the treatment of infratemporal fossa abscess (IFA). Study design. This retrospective study was conducted at the Deptartment of Oral and Maxillofacial Surgery of Hallym University and "Iuliu Hatieganu" University of Medicine and Pharmacy. Ten-year records of patients were reviewed in Romania and six-year records were reviewed in Korea. The collected data was then analyzed. Results. A total of 36 cases were found to be IFA (12 males and 24 females: average age; $36.3{\pm}15.5$ yrs: 34 cases from Romania and 2 cases from Korea). The annual frequency of IFA in Romanian and Korean hospitals was 3.40 and 0.33 respectively (P<0.001). The etiology was septic anesthesia (33.3%), infection occurring after extraction (30.6%), periapical lesion (13.9%), impacted third molar (8.3%), post-extraction alveolitis (5.6%), and unknown (8.3%). A successful outcome was seen in 27 patients (75.0%) after initial treatment. The main complication after initial treatment was restricted movement of the mouth (9 cases). Conclusion. The etiology of IFA was various and minimal swelling hampered early diagnosis. To prevent IFA, preoperative painting with antiseptic agent must be stressed and proper drainage proved important to relieve pain and to prevent further complications.

Recent advances in the surgical treatment of congenital disorders of the heart have necessitated an accurate preoperative diagnosis. Right heart catheterization has become widely accepted as a research tool and diagnostic test to detect the heart diseases, especially in the congenital heart anomalies. Right heart catheterizations were carried out in 50 cases of congenital heart diseases at Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital, during the period of June, 1975 through September 1978. In age distribution, 27cases were below 10 years of age, 18 cases between 11 and 20, and 5 cases above 20 male to female ratio was 2.8:1. The distribution of congenital heart diseases was VSD [42%], TOF [36%], PDA [10%], ASD [8%], and PS[4%]. Of these, 44 cases [88%], were compatible with the clinical impressions that were made preliminarily before cardiac catheterization, and all the cases except 1 case of VSD was correlated well with the postoperative diagnosis. The right heart catheterization is considered to be reliable and accurate toll in the preoperative diagnosis of congenital heart diseases. These procedures caused complications such as left side hemiplegia [lcase], occlusion of the femoral artery [lcase], and transient ventricular tachycardia [1case], and so the complication rate of right heart catheterization was 6% [3 cases]. None of patients who have undergone right heart catheterization was died.

Background: ATS mechanical valve is a recently introduced pyrolytic carbon bileaflet prosthesis. This report is to evaluate the results of hemodynamic and anticoagulant therapy after ATS valve replacement. Material and Method: From May 1995 to October 1998, 53 patients received 65 ATS prosthesis; 38 Mitral(27-33 mm), 27 Aortic(19-25 mm). 2 CABGs and 5 Tricuspid annuloplasty were taken concomitantly. The follow up period was 769 patient-months(mean 16.2$\pm$10.0), varied from 1 month to 39 months with 92.5% follow up rate. All patients were evaluated with Doppler echocardiography, 7-14 days after operation. Result: NYHA functional class was improved significantly, from 2.6$\pm$0.8 preoperatively to 1.3$\pm$0.4 postoperatively. The average value of peak and mean transvalvular pressure gradients were 25.7$\pm$13.5 mmHg, 12.7$\pm$8.3 mmHg in aortic position. In the mitral position, the average values of peak and mean transvalvular pressure gradient and valve area were 5.9$\pm$2.5 mmHg, 3.1$\pm$0.8 mmHg and 2.9$\pm$0.5 $\textrm{cm}^2$, respectively. In the anticoagulant therapy, mean INR was 2.5$\pm$0.6 in mitral valve replacement and 1.9$\pm$0.5 in aortic valve replacement. There was no anticoagulant related complication. During that period, there were 3 hospital death(5.9%) and 1 late death(1.9%). Conclusion: The early clinical results of the ATS heart valve replacement is quite satisfactory, and low target INR reginmen is safe. And long term follow of hemodynamic characteristics is also necessary.

Purpose: The necrotizing fasciitis is a terrifying infectious disease that can rapidly spreads to surrounding tissues when fascia is infected and it can cause sepsis to death if not properly diagnosed and treated. The purpose of this study is to investigate the characteristics, causes, and treatment methods of necrotizing fasciitis in Korea through reviewing patients admitted to our burn center. Methods: 21 patients with necrotizing fasciitis were selected for this study among those inpatients with electronic medical records (EMR) admitted to Hallym University Hangang Sacred Heart Medical Center from Jan 1, 2008 to June 30, 2019. The medical records and wound photos of those 21 selected subjects were reviewed. Results: There were 13 male and 8 female patients and mean age was 58.76 years old. 13 of 21 subjects were survived and 8 died (38% mortality rate). The surgical treatments performed were I&D, fasciotomy, debridement, allograft, burring, STSG, flap, and amputation. The most common causes were burns in 9 subjects (6 contact burns) and cellulitis occurred on skins in 5 subjects. And other various causes were observed as fournier's gangrene, stab wound, intramuscular injection, tumor and bleu toe syndrome (toe necrosis). The infected areas were 11 feet and legs, 7 hips, 3 abdomen and trunk in 21 subjects. Of the 8 deaths, 3 were infected in feet and legs, 2 were infected in hips, and 2 were infected in abdomen and trunk. As for underlying diseases, 12 patients with hypertension or diabetes were the highest and others such as cancer and stroke were found. Conclusion: The only method to increase the survival rate is to 'suspect' the disease as much as possible and perform early extensive excision. It is advisable to treat the disease by the burn center to properly provide adequate and optimal wound management, infection control, medical care and nutritional supports.

Cemento-ossifying fibroma (COF) is a benign fibro-osseous tumor with fibrous tissue, abnormal cement and bone, or a combination of such elements. These are slow-growing lesions and are more frequent in women. Here, we report the case of a 28-year-old Korean woman. The patient having no underlying disease complained about facial swelling and asymmetry. A firm mass with impacted molars and teeth deviation on the right maxilla was observed. A computed tomography scan was taken and an incisional biopsy was performed. Following this, COF was diagnosed. Complete surgical removal of the lesion was carried out. A post-operative follow-up was conducted and 3 months later the patient reported no discomfort or any sign of recurrence in regards to the lesion. Differential diagnosis with fibrous dysplasia and the COF is important because of the treatment choice. We report a case of COF and offer a review of the literature on this article.

Purpose: Lymphoma originated from mucosa associated lymphoid tissue(MALT) is most common in gastrointestinal system, and rarely found in salivary gland, thyroid, bronchus or orbit. We experienced a case of MALT lymphoma which was originated from conjunctiva and involving lower eyelid without metastasis. Methods: A 40-year-old man suffered palpable mass on right lower eyelid without pain. Orbital computed tomographic and ultrasonographic findings showed a conical mass($1.9{\times}1.2{\times}0.9cm$ size) inside lower eyelid. The mass was completely excised under local anesthesia and histopathological examination was followed. Results: Microscopic finding showed a multiple follicular colonization. In the follicle, small lymphocytes and plasma cells differentiated to centrocyte-like cell, monocyte B cell, plasma cell were diffusely infiltrated. Immunophenotyping was preformed on fixed section. The majority of the small cells were immunoreactive for the B cell marker CD20. Based on the typical histological findings supported by immunostaining, the mass was defined as MALT lymphoma. After excision, SPECT, abdominal CT was carried out and there were no evidence of extraorbital disease. Conclusion: Biopsy and pathological examination should be performed in patients who complain palpable mass on lower eyelid because of possibility of MALT lymphoma. Although MALT lymphoma is rarely metastasized, it is necessary to evaluate the extraorbital involvement using SPECT or other radiologic exams. For detecting extraorbital involvement, periodic follow-up examination is need.

Purpose: Since Rheinwald and Green laid the foundation of epidermal cell culture technology in 1975, many clinicians and scientists have attempted to prove the effectiveness of cultured epidermal autologous(CEA) or homogenetic(CEH) grafts in the wound healing process. In contrast to CEA which cultured from a patient's skin on demand, Cultured Epidermal Homograft(CEH) can be readily available to use on cleaned wounds. In this study, we conducted a controlled clinical trial in order to confirm the effectiveness of CEH in treating partial-thickness 2nd degree burn wounds. Methods: From July 2003 to January 2004 at Hangang Sacred Heart Hospital, we performed a clinical trial in which 35 patients who suffered from 2nd degree burns were enrolled. Wounds were randomly divided into two parts, control and test sites. Test sites were treated with allogeneic keratinocyte sheets ($Kaloderm^{(R)}$, Tegoscience Inc.), a CEH commercialized in Korea. Results: All wounds healed completely without any major complication. The complete healing took $8.3{\pm}2.8$($mean{\pm}S.D.$) days in the test sites as opposed to $11.7{\pm}3.3days$ in the control sites. Conclusion: Based on these results, we concluded that CEH accelerates re-epithelialization of partial thickness burn wounds and CEH can be an safe alternative to skin grafts for 2nd degree burns.
