Dissecting aortic aneurysm is an emergency condition which requires prompt diagnosis and management. From January 1992 to December 1996, 54 patients were admitted to our department. Patients were categorized according to the Stanford classification of aortic dissection and investigation of the clinical records utilized the retrospective method. Male constituted the majority, according for 38(70.4%) of the total number of patients, whereas females accounted for 16(29.6%). Mean age was 52.1+/-2.2 years old (range:25~82). Clinical findings included chest pain in 46 cases(85.2%), renal failure in 11(20.4%), aortic insufficiency in 10(18.5%) and stroke in 9(16.7%). Predisposing factors were hypertension in 48 cases(88.9%), Marfan's syndrome in 5(9.3%) and diabetes mellitus in 1(1.8%). 21 patients(type A:12, type B:9) underwent surgical treatment. There were three(2 in type A and 1 in type B) deaths in the surgical treatment group and nine(5 in type A and 4 in type B) deaths in the medical treatment group. These results reflect our current policy in the management of dissecting aortic aneurysm.

BACKGROUND: Trauma is the third leading cause of death, irrespective of age, and the leading cause of death in persons under 40 years of age. Computed tomography (CT) is an effective technique in the initial emergent evaluation of the abdomen and head following blunt trauma. Most chest indies are not seen on conventional chest radiography, or may be underestimated. But routine use of CT in the initial emergent evaluation of chest trauma is controversial. CT, however, has been shown to be useful in the diagnosis of unsuspected chest injuries and in directing therapeutic interventions. This review discusses the efficacy of emergent CT in patients with blunt trauma on the chest. METHODS: To evaluate the efficacy of CT of the thorax, a retrospective study comparing early thoracic CT scanning with initial chest roentgenogram(CXR) was carried out on 121 patients with blunt trauma on the chest. The interval between CXR and CT was less than 1 hour. RESULTS: Among 121 patients, 42 patients had normal initial chest roentgenogram in whom 19 patients showed normal CT findings. Sensitivities of diagnosing pneumothorax and pleural effusion by CXR were low (49.3%and 45.1%respectively), whereas 65.7% (44/67) of patients had thoracostomy only by CXR. CONCLUSIONS : Although sometimes abused in patients with chest trauma, CT of the thorax is an effective method of detecting thoracic injuries and provides accurate information regarding their pattern and extent in the initial emergent diagnosis.

BACKGROUND: The automated border detection(ABD) echocardiography has the ability of recognizing the endocardial-blood interface, and therefore, on-line estimation of the left ventricular(LV) volume every cardiac cycle. Compared with the off-line conventional 2-dimensional echocardiographic method that requires tracing the endocardial border manually, the ABDd system can be a convenient and objective method in the estimation of the LV volume and the ejection fraction(EF). The purpose of this study is to compare the LV volume and EF between the on-line ABD system and the convertional off-line echocardiographic method. METHODS: In two weeks, 83 adult patients older than 16 years of age were referred to our echocardiographic laboratory. Among these 83 patients, 64 patients who had a normal sinus rhythm were included to our study. Using the Hewlett-Packard SONOS 1500, a 2.5 MHz transducer was placed dat the cardiac apex. Patients with an apical 4 chamber view of the LV in which at least 75% of the endocardium was clearly seen were selected for study. On that view, the ABD system was turned on, and the reansmit power and the time-gain compensation controls were adjusted in order to approximate the automated border to the visually apparent endocardial surface. The LV end-diastolic volume(LVESV) and LV end-systolic volume(LVESV) were calculated by the method of disc. LVEDV, LVESV, and EF were displayed every cardiac cycle. Also the off-line estimation of the LV volume was performed by the method of disc, after manually tracing the endocardial border on the apical 4 chamber view. RESULTS: 44 patients(69%) of 64 patients had > or =75% of the LV endocardium visualized. LVEDV, LVESV, and Ef with the ABD system were highly correlated with those with the off-line, manually traced method(r=0.95, 0.8, respectively), but LVEDV and EF with toe ABD system were significantly less than those with the latter(p<0.01). The limits of agreement between tow methods(off-line, manually traced method-ABD system) were somewhat wide. Those of LVEDV, LVESV and EF were +22~-10ml(mean 6ml), +15~-14ml(mean 0.1ml), and +19~-12%(mean 3.8%), respectively. CONCLUSION: LVEDV,LVESV, and EF measurements by the ABD system and the off-line manually traced methods thve a strong correlation, The ABD system should habe clinical applications in setting, in which measurements of LV volume and Ef are important, But, the comparison with a more reliable method is necessary.

BACKGROUND: Overweight and obesity are associated with increased mortality and morbidity. Obesity is influenced by multiple factors, both genetic and environmental factors. We investigated the relationship between socioeconomic, behavioral, dietary, reproductive factors and body mass index(BMI). METHODS: The subject were 3000 adults who had visited the Health Screening and Diagnosis Center of Yeungnam University School of Medicine from February to June, 1997. We evaluated BMI and occupation, exercise, smoking, alcohol intake, total calory intake, fat and carbohydrate intake in both gender and reproductive factors in women. Then, we analyzed the association between BMI and such variables as above. RESULTS: 1629 men and 1371 women were analyzed. The mean BMI was 23.4+/- 2.8kg/M(2) in men, 22.9+/- 3.1kg/M(2) in women. In both gender, 9.7% of our population had BMl over 27. Mean BMI increased with age. Those who were active and light smokers( 20cigarette/day) had the lowest BMI in men. But no relationship was observed between BMI and exercise, smoking in women. Heavy alcohol drinkers(> 1cup/day) had higher BMI than other group in both gender. We found significant correlation between BMI and total calory intake, calory intake to recommended calory ratio in both gender. In women, the group whose number of parity was above 3 had significantly higher BMI than the other. And age at first birth was significantly correlated with BMI in a negative direction. CONCLUSIONS: Our results showed that BMI was associated with age, smoking, alcohol, total calory intake, calory intake to recommended calory ratio, parity, age at first birth. Socioeconomic class, exercise and diet composition appeared to have little influence.

Zika virus (ZIKV) is a vector-borne flavivirus. It was initially identified in Uganda in 1947, and the first human infection was reported in Nigeria in 1953. Since 2015, ZIKV has been spreading rapidly in Brazil and the Americas. Given its general symptoms, ZIKV is considered to be a mild, febrile illness, although it is associated with severe neurologic complications. On February 1, 2016, the World Health Organization (WHO) declared a Public Health Emergency of International Concern (PHEIC). We conducted a review of the literature on the epidemiology and transmission, clinical manifestations, and diagnosis of ZIKV. Additionally, we introduce original literature on the current ZIKV outbreak in this review.

PURPOSE: The purpose of this study is to evaluate the usefulness and limitation of QuantiFERON-TB Gold (QTB) for diagnosis of latent tuberculosis in children. METHODS: The medical records of 112 children who were tested by tuberculin skin test (TST) and QTB for detection of latent tuberculosis (TB) in Eulji General Hospital during the period from January 2007 to June 2009 were retrospectively reviewed. RESULTS: Of the 112 participants, the clinical TB group included 15 (13.4%), the contact group included 43 (38.4%), and the non-contact group included 54 (48.2%). Positive rates of TST and QTB were 100% and 80% in the clinical TB group, 64% and 14% in the close contact group, 27% and 0% in the casual contact group, and 52% and 2% in the non-contact group, respectively. Sensitivity of QTB was 80.0% and specificity was 92.6%. Agreement between QTB and TST was poor (kappa=0.209). We also confirmed that the positive rate of QTB increased as the age of the patient increased (P=0.011). A QTB indeterminate result was observed in 11 (9.8%) subjects. QTB was retested in 15 subjects. In 5 of the 6 subjects who had positive results initially, positive results persisted for a median 2.2 months after termination of treatment. CONCLUSION: Although QTB was associated with several problems, including low sensitivity and a high rate of indeterminate results, it had clinical importance due to its high specificity. We found good correlation with regard to exposure and QTB positivity, including that of young children under 5 years of age. However, clinical application of interferon-gamma releasing assay for young children for diagnosis of active and latent tuberculosis will require additional prospective studies.

An aortoesophageal fistula (AEF) is an extremely rare, potentially fatal condition, and aortic surgery is usually performed together with extracorporeal circulation. However, this surgical method has a high rate of surgical complications and mortality. This report describes an AEF caused by tuberculous esophagitis that was treated successfully using a two-stage operation. A 52-yr-old man was admitted to the hospital with severe hematemesis and syncope. Based on the computed tomography and diagnostic endoscopic findings, he was diagnosed with an AEF and initially underwent thoracic endovascular aortic repair. Esophageal reconstruction was performed after controlling the mediastinal inflammation. The patient suffered postoperative anastomotic leakage, which was treated by an endoscopic procedure, and the patient was discharged without any further problems. The patient received 9 months of anti-tuberculosis treatment after he was diagnosed with histologically confirmed tuberculous esophagitis; subsequently, he was followed as an outpatient and has had no recurrence of the tuberculosis or any further issues.
