With the ligation of patent ductus arteriosus by Gross in 1938, surgeons first entered the field of congenital heart disease. Interruption of a ductus is one of the most satisfactory and curative operations in the field of surgery for congenital heart disease. 27 cases of isolated patent ductus arteriosus were operated from Jan. 1978 to July 1984 at the Department of Thoracic & Cardiovascular Surgery in Kyung-Hee University Hospital. Retrospective clinical analysis of these patients were: 1. Sex ratio, female: male, was 2:1. 2. Mean age at operation was 9.85\ulcorner.58 years. The youngest patient was a 23 month-old girl and the oldest one was a 24 year-old male. 3. More than half of the patients had less than 50 percentile of growth retardation. 4. Chief complaints of the patients were frequent URI [52%], dyspnea on exertion [33%], generalized weakness [22%], palpitation [7%], but 7 patients [26%] had no subjective symptoms. 5. Continuous machinery murmur could be heard at the 2nd or 3rd intercostal space on the left sternal border in 22 patients [81%]. The other S patients made systolic murmur with accentuation of the second heart sound and those were associated with pulmonary hypertension. 6. Radiologic findings of Chest P-A were cardiac enlargement in 15 patients [55%], enlargement of pulmonary conus and/or increasing density of pulmonary vascularity in 20 patients [74%]. 7. Electrocardiographic findings of the patients were within normal limit in 13 patients [48%], LVH in 4 patients [15%], biventricular hypertrophy in 3 patients [11%]. 8; echocardiogram was obtained from 11 patients. Ductus was directly visualized in 7 patients. Left atrial enlargement is the secondary change of left to right shunt, 10 patients had LA/Ao ratio more than 1.2. 9. Cardiac catheterization performed in 25 patients. The mean value of the results were:SO2[PA-RV]= 14.72\ulcorner6.01%, Qp/Qs=2.22\ulcorner.80, peak systolic pulmonary arterial pressure=48.28\ulcorner1.60 mmHg. 10. 26 patients were operated through the left posterolateral thoracotomy: closure of ductus by double ligation in 14 cases, triple ligation in 5 cases, and division with suture in 8 cases. One patient suffer from aneurysmal rupture of main pulmonary artery, endocarditis, hemopericardium was treated with cardiopulmonary bypass via median sternotomy and closure of ductus through the ruptured main pulmonary artery. 11.There was no death associated with the operation, but 3 cases were experienced with intraoperative rupture around the ductus resulting in massive bleeding. The other complications were transient hoarseness in one patient, atelectasis in left lower lobe in 3 patients, and postoperative systemic hypertension in 4 patients with unknown etiology. 12. Pulse pressure was reduced, 11.47+5.92 mmHg, postoperatively, as compare to preoperative status. 13. Intraoperative wedge lung biopsy from lingular segment for the evaluation of the pulmonary vascular disease was taken in S patients with severe pulmonary hypertension. The result was Heath-Edward grade I in one case, grade II in two cases, and grade III in two cases.

To investigate the diagnostic accuracy and applicability of barium enema(BE) and rectal suction biopsy with acetyl cholinesterase(AChE) histochemistry in the diagnosis of neonatal Hirschsprung's disease(HD), we retrospectively reviewed the findings of BE and AChE staining in 96 neonates with suspected HD during a 10-year period from January 1991 to December 2000. Sixty-nine cases of HD(58 males and 11 females) and 27 cases of non-HD are included in this study. In regard to BE, HD was based on definite transitional zone, suspicious HD on reversed rectosigmoid index(RSI <1), and non-HD on normal RSI(RSI>1). The histochemical criterion used for the diagnosis of HD was that of Chow et al(1977), i.e., the presence of many coarse discrete cholinergic nerve fibers in the muscularis mucosae and in the immediately subjacent submucosa regardless of infiltration of cholinergic nerve fibers in the lamina propria. Of 66 neonates with HD who underwent BE, transitional zone was identified in 33 cases(50 %) and reversed RSI in 19 cases(21 %), microcolon in 4 cases and normal finding in 10 cases(15 %) while of 27 neonates with non-HD, there was normal finding in 16 cases and reversed RSI in 9 cases(41 %). Thus diagnostic accuracy based on transitional zone was 64 %. The positive predictive value of reversed RSI for the diagnosis of HD was 68 %. Of 42 neonates with HD who underwent AChE histochemistry, there were 41 AChE-positive reactions and one AChE-negative reaction in a neonate with total colonic aganglionosis, while of 27 cases of non-HD, there were one equivocal AChE-positive reaction and 26 AChE-negative reactions. Thus AChE histochemical study showed a 97 % diagnostic accuracy with a 98 % sensitivity and a 96 % specificity. In conclusion, we believe that BE is valuable as a first diagnostic step since about 80 % of neonates with HD show significant radiologic findings such as a transitional zone or reversed RSI. AChE histochemical study was a more reliable diagnos tic tool showing a 97 % diagnostic accuracy, and is part.

The incidence of Adenovirus(AV) pneumonia in children is estimated at 8%. Long-term complications reported with type 7 include hyperleucent lung syndrome, bronchiolitis obliterans and may require several months to recover. We reviewed 8 case of AV pnemonia confirmed by AV culture and sero-diagnosis among selected 19 AV pneumonia suspicious cases who were admitted to the Sanggye Paik Hospital of Inje University due to clinical pneumonia from May to July 1996. From 19 children, nasal aspirates or trachial aspirates were collected: viral agents were detected by virus isolation and virus antigen was detected by indirect immunofluorescent staining. Serologic diagnosis for type-specific AV antibody was done by neutralisation test. The results are as follows: 1) Age of the patients ranged from 6 months to 47 months with a mean of $24{\pm}9$ months. 6 were male and 2 were female(M:F= 3:1). 2) Monthly distribution showed 4 cases on June, 2 cases on May and July, respectively. 3) The mean duration of admission was 20.4 days and mean duration of fever was 11.3 days 4) Peripheral leukocyte counts were elevated in 4 cases(50%) and findings of shift to left were showed in 4 cases(50%) and serum aminotransferase activities were elevated in 6 case(75%). 5) Radiologic findings include linear and streaky infiltration(1/8 cases), patchy and lobar consolidation (7/8 cases), pleural effusion(2/8 cases) and hyperleucency was seen in 3/8 cases at time of admission and increased to 6/8 cases on hospital discharge. 6) The AV serotypes were type 7, type 3, and type 1. 7) Oxygen supply was done in 4 cases(50%) and all 8 patients include 2 cases of type 7 treated with artificial ventilator were survived. In conclusion, the serotypes of AV pneumonia outbreaks in early summer of 1996 were type 7, 3, 1 and, as showed severe clinical course, continued follow up surveillance is necessary to the long term pulmonary complications.

Background: A tuberculous destroyed lung is sequelae of pulmonary tuberculosis and causes various respiratory symptoms and pulmonary dysfunction. The patients with a tuberculous destroyed lung account for a significant portion of those with chronic lung disease in Korea. However, few reports can be found in the literature. We investigated the computed tomography (CT) findings in a tuberculous destroyed lung and the correlation with lung function. Methods: A retrospective analysis was carried out for 44 patients who were diagnosed with a tuberculous destroyed lung at the Keimyung University Dongsan Hospital between January 2004 and December 2009. Results: A chest CT scan showed various thoracic sequelae of tuberculosis. In lung parenchymal lesions, there were cicatrization atelectasis in 37 cases (84.1%) and emphysema in 13 cases. Bronchiectasis (n=39, 88.6%) was most commonly found in airway lesions. The mean number of destroyed bronchopulmonary segments was 7.7 (range, 4~14). The most common injured segment was the apicoposterior segment of the left upper lobe (n=36, 81.8%). In the pulmonary function test, obstructive ventilatory defects were observed in 31 cases (70.5%), followed by a mixed (n=7) and restrictive ventilatory defect (n=5). The number of destroyed bronchopulmonary segments showed a significant negative correlation with forced vital capacity (FVC), % predicted (r=-0.379, p=0.001) and forced expiratory volume in one second ($FEV_1$), % predicted (r=-0.349, p=0.020). After adjustment for age and smoking status (pack-years), the number of destroyed segments also showed a significant negative correlation with FVC, % predicted (B=-0.070, p=0.014) and $FEV_1$, % predicted (B=-0.050, p=0.022). Conclusion: Tuberculous destroyed lungs commonly showed obstructive ventilatory defects, possibly due to bronchiectasis and emphysema. There was negative correlation between the extent of destruction and lung function.

Purpose : To assess the clinical findings and hard tissue changes of osteomyelitis of the jaws using computed tomographic (CT) image analysis. Materials and Methods : We reviewed and interpreted the CT images of 163 patients (64 males and 99 females, age range from 10 to 87 years) who visited the Seoul National University Dental Hospital from April 23, 2006 to December 31, 2008 and were diagnosed as osteomyelitis of the jaws through clinical, radiologic, and histopathologic examination. Each CT findings was investigated for frequency, correlation with age and gender. Results : Of the 163 patients, 31 (19.0%) were affected on the maxilla, 135 (82.8%) were affected on the mandible, and 3 (1.8%) were affected on the both jaws simultaneously. The mean age of the patients who were affected on the maxilla was 61.0 years and that of the patients who were affected on the mandible was 56.2 years. On the maxilla, the most frequent site of disease was the posterior area (83.9%) and on the mandible, mandibular body (83.0%), followed by angle (48.1%), ramus (38.5%), condyle (13.3%), incisal area (9.6%), and coronoid process (3.0%). Among the 31 maxillary osteomyelitis, defect in the trabecular bone was observed in 28 (90.3%), osteosclerosis 20 (64.5%), defect in the cortical bone 27 (87.1%), sequestrum 17 (54.8%), and periosteal reaction 2 (6.5%). Among the 135 mandibular osteomyelitis, defect in the trabecular bone was observed in 100 (74.1%), osteosclerosis 104 (77.0%), defect in the cortical bone 116 (85.9%), sequestrum 36 (26.7%), and periosteal reaction 67 (49.6%). Conclusion : Of our cases, the maxillary osteomyelitis was visibly observed more frequently in females than males. The incidence is the highest in seventies (28.8%) and the lowest in teens (3.1%). The osteomyelitis of the jaws was observed more frequently in males than females before the age of 50, and observed more frequently in females after the age of 50. The most noticeable point was that the sequestrum was observed more often on maxillary osteomyelitis and the periosteal reaction was observed more often on mandibular osteomyelitis.

Background: The aim of the present study was to evaluate whether findings on initial chest computed tomography (CT) of influenza pneumonia can help predict clinical outcome. Methods: We reviewed all adult patients admitted to the Emergency Department (ED) with a confirmed diagnosis of novel influenza A H1N1 virus (2009 H1N1) pneumonia, who underwent chest CT upon admission between Aug 26, 2009 and Jan 31, 2010. Radiologic findings were characterized by type and pattern of opacities and zonal distribution. Clinical outcome measures were intensive care unit (ICU) admission, mechanical ventilation, and inhospital death. Results: Of 59 patients diagnosed with 2009 H1N1 pneumonia, 41 (69.5%) underwent chest CT on admission into ED. Nine (22%) of these patients developed adverse clinical outcomes requiring the following treatments: 9 (22.0%) ICU admissions, 5 (12.2%) mechanical ventilation, and 3 (7.3%) inhospital deaths. Counting the number of patients with more than 4 involved lobes, the sensitivity, specificity, positive predictive value, and negative predictive value for detection of adverse clinical outcome were 67%, 84%, 55% and 80%, respectively. Conclusion: Extensive involvement of both lungs (over 4 lobes) is related to ICU admission, mechanical ventilation, and inhospital death. Initial chest CT may help predict an adverse clinical outcome of patients with 2009 H1N1 influenza pneumonia.
