Broncho-gastric fistula caused by benign gastric ulcer perforation after esophagectomy is very rare. In general anesthesia of a patient with broncho-gastric fistula, in spite of hyperventilation, leakage of the anesthetic gases through fistula may make the patient hypercapneic, and positive pressure ventilation may increase the risk of the pulmanary aspiration by the regurgitation of gastric fluid by stomach distension. For that reason, in this patient, denitrogenation was performed during patient's voluntary respiration with 100% oxygen for 5 minutes, and induction was performed without positive pressure ventilation, and one lung ventilation was carried out. Hypoxemia was followed by one lung ventilation because his pulmonary function was moderate obstructive type and his lung was damaged by aspiration of gastric fluid via broncho-gastric fistula. A low level of continuous positive airway pressure (CPAP) has no significant hemodynamic effect and can maintain the patency of nonventilated lung, so hypoxemia induced by one lung ventilation may be reduced. Thus we carried out one lung ventilation with CPAP (10 cmH2O) in nonventilated lung and blocked broncho-gastric fistula with a bronchial blocker for prevention of both regurgitation of gastric fluid and leakage of anesthetic gases. One lung anesthesia was performed without any problem in this case.

BACKGROUND: The aging of the patient population is one of rhe most important factirs influencing health care delivery. Currently 5% of the Korean population is elderly, defined as older than 65years of age, with this group projected to increase to 13.1% by the year 2021. Cardiovascular disease is the leading cause of death and of disability in the elderly age group. mong them, coronary heart disease is the most importane. METHOD: Study population composed of 216 patients who were admittied to the hospital with first acute myocardial infarction and they were divided into two groups according to the age(older than 65 years of age vs younger). Clonical features, risk factors of coronary heart disease, in-hospital outcome and complication were compared in elderly patients and others group. Results : 1) The risk factors of coronary heart disease is similar to younger patients but pattern of chest pain is less typical than younger patients. 2) Clinical presentation of elderly patients is similar to younger patients except Killip class on admission.(1.66vs 1.91,P=0.04) 3) In-hospital mortality of elderly patients in higher than younger patients. In addition to an increased incidence of death, recurrent ischemia, stroke, AV block, ventricular arrythmia, pulmonary edema occured more frequently with advanced age. 4) Especially in the thrombolytic therapy group, in-hospital death, reinfarction and recurrent ischemia is higher than primary PTCA group in elderly patients. CONCLUSIONS: Diagnosis of acute chest pain is difficult in elderly patients and in-hospital mortality and morbidity is higher than in younger patients. Thus more accurate diagnosis and discriminative therapeutic modality is needed.

BACKGROUND: Despite extensive investigation, the clinical features and prognostic significance of the non-Q wave myocardial infarction, when compared with Q wave myocardial infarction, remain controversial. And no definite relationship between EKG findings and infarct related arteries has been reported. METHOD: A retrospective analysis was done on 205 patient with acute myocardial infarction who were undergone coronary angiography and left ventriculography. Among them, 30 patient with non-Q wave myocardial infarction and 175 patients with Q wave myocardial infarction. RESULTS: 1) There was no significant difference between the two groups in risk factors, prevalence of preinfarct angina and preinfarct heart failure. 2) The faction of patients with non-Q wave myocardial infarction who received thromobolytic therapy was significantly less, compared to patient with Q wave myocardial infarction(p<0.0001). 3) The patients with non-Q wave myocardial infarction had a smaller infarct size estimated by peak creatine phosphokinase(p<0.01). But there was no difference in Killip's classification and left ventricular ejection fraction. 4) In patients with non-Q wave myocardial infarction, 87% of the patients had one or more abnormal EKG finding other than Q wave, and the most frequent abnormal finding was primary T wave change. 5) The location of infarct-related artery was significantly different between group(p<0.0001). The most frequently involved coronary artery in non-Q wave myocardial infarction was left circumflex coronary artery, especially in patients with normal EKG findings. 6) There was no significant difference between the two groups in the prognosis. CONCLUSION: There were significant differences between non-Q wave and Q wave myocardial infarction in the infarct size and the location of infarct related arteries. but not in the risk factors, the prevalence of previous coronary artery disease and prognsis. Further prospective and collaborative studies should be performed to define conclusion.

The toxic effect of azalea extract, especially on cardiovascular system, in relatively unclear. The purpose of this study is to study the possible underlying mechanism and effect of toxic ingredient of azalea on cardiovascular system. The 71 healthy rabbits were divided into 10 groups: In group as preliminary study; 4 cc of normal saline was administered intravenously (N); 0.7 gm/kg and 1.0 gm/kg of azalea extract was administered respectively in the same route, volume (A1, A2); atropine was administered intravenously (A); after pretreatment with atropine (0.04 mg/kg) to block parasympathetic system, azalea extract was injected like the above groups (AA1, AA2); normal saline, 0.7 gm/kg and 1.0 gm/kg of azalea extract were administered respectively with 0.2 cc (1:1000) epinephrine (E0, E1, E2). We measured the following indices at I minute interval during first 10 minutes and then 10 minute interval during next 30 minutes: RR interval, QTc interval, maximal systolic and diastolic pressure drop with occurring time and presence of significant arrhythmia. The results were as follows: 1. The changes of RR interval, QTc interval were significantly increased in groups by Azalea extract. The blood pressure change was significantly decreased in groups by Azalea extract. There were no significant differences according to dosage of Azalea extract. 2. The changes of RR interval, blood pressure were significant differences between administration of atropine and Azalea extract after pretreatment with atropine, but not in the change of QTc interval. 3. There were no significant differences in the change of RR interval, ATc interval, blood pressure drop according to pretreatment with atropine. 4. The interaction between epinephrine and Azalea extract was not noted by the effect of epinephrine itself. 5. The ST change by 0.7 gm/kg, 1.0 gm/kg of Azalea extract was revealed in 1 case (14.0%), 7 case (100%), respectively. 6. Most of all cases with arrhythmia, ventricular tachycardia, ventricular fibrillation, were noted in the group by epinephrine, except on case by Azalea extract (1.0 gm/kg). It was idioventricular rhythm. In conclusion, azalea extract has negative inotropic and chronotropic effect with arrhythmogenic potential possibly through direct myocardial ischemia or injury but we can't be absolutely exclusive of actions of autonomic nervous system, especially parasympathetic nervous system.

PURPOSE: To evaluate the usefulness of magnetic resonance imaging (MRI) for assessing fracture types and soft tissue injuries associated with tibial plateau fractures. MATERIALS AND METHODS: MRI was performed in 38 patients with tibial plateau fractures, each of which was classified according to the Schatzker system. We evaluated MR images and assessed the prevalence of each fracture type and accompanying soft tissue injuries. We also assessed whether ligamentous injury correlated with the extent of articular depression, splitting, and comminution. In 24 patients, diagnosis was based on MRI and operative or arthroscopic findings, and in 14 patients, on MRI alone. RESULTS: The totals of fracture types I, II, III, IV, V and VI were 4 (11 %), 15 (39 %), 6 (16 %), 4 (11 %), 4 (11%), and 5 cases (13 %), respectively. In 30 cases (79 %), there were associated ligamentous or meniscal injuries. Medial collateral ligaments and lateral menisci were injured in 17 (45 %) and 14 cases (37 %), respectively. Type II and IV fracture patterns were associated with soft tissue injuries in 14 of 15 cases (93 %) and 4 of 4 cases(100 %), respectively. As the extent of articular depression increased and the extent of bony comminution decreased, there was an increased prevalence of accompanying ligamentous injuries. CONCLUSION: In tibial plateau fractures, MR imaging is a useful diagnostic modality for the evaluation of both fracture type and accompanying ligamentous or meniscal injuries.

The incidence of anomalous aortic origin of the coronary arteries in the general papulation is unknown. In recent reports from various laboratories, the incidence was between 0.6-12% in patients referred for coronary arteriogtaphy. Anomalous origin of the right coronary artery from the left sinus of Valsalva is reported to constitute from 6% to 27% of all coronary anomalies, For many years pathologists classified it as a minor anomaly of no clinical importance. Recently, manifstations of myocardial ischemia have been described in patients with this anomaly in the absence of additional atherosclerotic or other disease processes. These manifestations have included acute myocardial infarction, angina pectoris, syncope, nonfatal ventricular fibrillation, and sudden death. We report a case of 56-year-old male with the anomalous origin of the right coronary artery from the left sinus of Valsalva, who had been admitted due to severe substernal chest pain and acute inferior wall myocardial infarction. The coronary angiography revealed that the right coronary artery originated from the left coronary sinus without significant atheroscleotic narrowing. The anomalous right coronary artery passed anteriorly between pulmonary artery and aortic root without significant coronary obstruction.

PURPOSE: The purpose of this study was to compare outcomes for surgical treatment with those for medical treatment of GB dyskinesia. METHODS: Retrospective analysis of medical records and telephone interviews of 67 patients diagnosed with GB dyskinesia was done at Pohang St. Mary's Hospital between January 2004 and December 2009. Group 1 (n=18) patients received laparoscopic cholecystectomy. Group 2 (n=49) patients received medical treatment. GB dyskinesia was the diagnosis if the patient had typical biliary colic symptoms without GB stones or other GI disease, and if the ejection fraction was less than 35% on Tc-99m-DISIDA scans. RESULTS: The average age of patients diagnosed with GB dyskinesia was 45.8 years old. The sex ratio was 15:52 (male:female). The average symptom duration was 25.4 days. All had RUQ and, or epigastric pain. There were no significant between group differences in age, sex ratio, symptom duration, symptoms, follow up period, and ejection fraction. In group 1, patient symptoms improved after treatment in 16 cases (88.9%); in group 2, patient symptoms improved in 19 cases (38.8%). Surgical treatment was significantly more effective than medical treatment. The reasons for choosing medical treatment were predominantly the preference of the doctors. CONCLUSION: Surgical treatment is a more effective treatment for GB dyskinesia than medical treatment. Therefore, laparoscopic cholecystectomy should be considered as the 1st line treatment of choice for GB dyskinesia.

The coronavirus disease-19 (COVID-19) pandemic leaded to inevitable expeditious vaccine rollout without sufficient safety profile. Especially, severe acute respiratory syndrome coronavirus 2 infection has known to induce overreacted immune responses such as releasing of proteinase-3 and myeloperoxidase (MPO) by neutrophil. This overreacted immune response leads to the concern of the development of autoimmune diseases after COVID-19 vaccination. We report the case of de novo MPO-associated systemic vasculitis involving central nervous system following heterogeneous mRNA1273 COVID-19 booster vaccination.

BACKGROUND: Recent guidelines recommend that all cirrhotics undergo screening upper endoscopy to identifly risk patients for bleeding from varices. The aim of this study was to determine whether clinical and laboratory variables were predictive of the occurrence and progression of esophageal varices. METHODS: This is a retrospective analysis of cirrhotics who had a screening upper endoscopy during 10 years after liver biopsy. Fifty-eight patients were recruited. Univariate/multivariate analysis was used to evaluate associations between the development and progression of esophageal varices and patients characteristics including platelet count, liver chemistry value, prothrombin time, shunt index(heart to liver uptake ratio) through transrectal TI-201 liver scan, probability(P)-value (Y=3.3431-0.8160 x ALT/AST ratio-0.0343 x prothrombin time+2.6963 x shunt index, P=e(y)/(e(y)+1)), ascites, splenomegaly, hepatic encephalopathy. RESULTS: There were 36 patients without esophageal varices or with stable varices during 10 years and 22 patients with new developed esophageal varices or progressive varices during 10 years as determined by upper endoscopy. On multivariate analysis, patients with a probability(P)-value of > or = 0.647 and a platelet count of < or = 100,500/mm3 had a risk of the development and progression of esophageal varices. CONCLUSIONS: Non-endoscopic predictors (probability(P)-value and platelet count) could be used to stratify patients with cirrhosis for the risk of the development and progression of esophageal varices and such stratification could be used to improve the effectiveness of screening upper endoscopy for esophageal varices.
