A total of 322 patients with endobronchial tuberculosis (8.1%) out of 3,982 subjects who had a flexible fiberoptic bronchoscopic examination at the Department of Pulmonary Medicine of Hanyang University Hospital between the beginning of March 1982 and the end of April 1996 were included in this study. The peak incidence occurred in the second decade, and the male to female was 1 : 3.0. The barking cough with variable amounts of sputum was the most common chief complaint in 56.9% of the 313 patients. Other complaints included dyspnea, chest pain, fever, hemoptysis, and generalized weakness. Localized wheeze was heard over the chest in 16.9% of the 313 patients. Infiltration/consolidation was the most common roentgenographic finding of the chest in 64.2%. Bronchoscopically, hypertrophy with luminal narrowing was the most common findings in 32.3% of the 322 patients and left main bronchus was the most frequently involved in 24.0%. Using fiberoptic bronchoscopy allows not only substantial meaningful assessment of endobronchial tuberculosis but also makes a differential diagnosis of lung cancer in older patients. We need further evaluations of standard bronchoscopic classification of endobronchial tuberculosis, diagnostic accuracy of endobronchial tuberculosis by PCR, a large prospective study of effects of corticosteroids in endobronchial tuberculosis patients, and appropriate treatment of atelectasis by endobronchial tuberculosis.

A 51-year-old male was admitted due to mediastinal mass. Chest PA showed a $4{\times}5$ cm sized round mass on right lower paratracheal area. The chest computerized tomogram showed cystic mass located between superior vena cava and trachea. This cystic mass was composed of variable internal architecture with Hounsfield unit(HU) from -44.4 to +25.5. The resected cystic mass revealed ectodermal, mesodermal, and endodermal structures. We report a case of anterior mediastinal cystic teratoma confirmed by open thoracotomy.

폐포단백증은 폐포에 표면활성제 기원의 인지질이 비정상적으로 다량 침착하는 드문 질병으로 자연 소실에서 호흡부전으로 인한 사망까지 다양한 임상경과를 보인다. 그 원인에 따라 선천성, 특발성, 이차성으로 나눌 수 있는데 GM-CSF의 작용경로의 이상이 중요한 병인으로 여겨지고 있다. 치료의 표준은 기관지 폐포세척술이며, 약 8%정도에서는 자연소실 되는 것으로 보고되었다. 저자들은 진단을 위해 흉강경하 쐐기 절제술을 시행하고 경과 관찰하던 중 자연 소실된 폐포단백증 환자를 경험하였기에 문헌고찰과 함께 이를 보고하는 바이다.

Purpose: Congenital diaphragmatic hernia (CDH) is rare but potentially fatal. The overall outcome is highly variable. This study aimed to identify a simple and dynamic parameter that helps predict the mortality of CDH patients in real time, without invasive tests. Methods: We conducted a retrospective chart review of 59 CDH cases. Maternal and fetal information included the gestational age at diagnosis, site of defect, presence of liver herniation, and lung-to-head ratio (LHR) at 20 to 29 weeks of gestational age. Information regarding postnatal treatment, including the number of days until surgery, the need for inhaled nitric oxide (iNO), the need for extracorporeal membrane oxygenation (ECMO), and survival, was collected. The highest respiratory severity score (RSS) within 24 hours after birth was also calculated. Results: Statistical analysis showed that a younger gestational age at the initial diagnosis (P<0.001), a lower LHR (P=0.001), and the presence of liver herniation (P=0.003) were prenatal risk factors for CDH mortality. The RSS and use of iNO and ECMO were significant factors affecting survival. In the multivariate analysis, the only remaining significant risk factor was the highest preoperative RSS within 24 hours after birth (P=0.002). The area under the receiver operating characteristic curve was 0.9375, with a sensitivity of 91.67% and specificity of 83.87% at the RSS cut-off value of 5.2. The positive and negative predictive values were 82.14% and 92.86%, respectively. Conclusion: Using the RSS as a prognostic predictor with simple calculations will help clinicians plan CDH management.

안검열의 외하방 편위, 관골 형성부전, 하악골 형성부전, 하악 후퇴증, 소이증, 설하수, 구개열 등의 소견으로 간헐적인 청색증, 흉곽 함몰, 급성 기도 폐색에 의한 호흡곤란과 연하곤란 등의 임상 소견을 나타낸 Treacher Collins 증후군을 가진 환아에서 출생직후에 구강저골막하박리술과 설구순접합술을 이용한 외과적 치료를 시행한 결과 급성 기도 폐색에 의한 호흡곤란과 수유장애의 해소 뿐만 아니라 혀의 전방 재위치 등 만족할 만한 결과를 얻을 수 있었다. 향후 성장이 완료될 때까지 주기적 경과 관찰을 시행할 예정이며, 성장과정 중에 발생할 두개안면기형에 대해서는 정신사회학적 측면을 고려하여 가능한 한 조기에 교정해주고, 어느 일부분에 국한된 수술보다는 안면윤곽을 고려하여 복합적인 수술을 시행해야 할 것으로 사료된다.

Pulmonary function tests were conducted on 815 healthy primary school children (390 males and 425 female) in rural area using Collins Survey Spirometer (Warren E. Collins, Inc., U.S.A.) with X-Y Recorder. Respiratory symptoms(cough, sputum, sore throat, chest pain, chest tightness, dyspnea, coryza) were surveyed by the interviews. Multiple regression analysis and regression diagnostics were done for prediction equations of FVC, $FEV_1,\;PEFR\;and\;FEF_{25-75%}$. FVC, $FEV_1,\;PEFR\;and\;FEF_{25-75%}$ values in 3 groups of children classified by the number of symptom were compared each other through standard variable value. FVC, $FEV_1,\;PEFR\;and\;FEF_{25-75%}$ showed highly significant correlation with age, height and weight. Prediction equations for FVC, $FEV_1,\;PEER,\;FEF_{25-75%}$ are functions of height only in both male and female children aged between 6 and 12 years old. PEFR showed a significant difference related with the number of symptom in female. These results suggest that the PEFR is sensitive PFT parameter in this study.

Porcine ear necrosis syndrome is characterized by erosive and ulcerative lesions at the margin or tip of the pinna. Three growing pigs of different ages exhibited retarded growth accompanied by reddening and necrosis of ear prior to death. Gross examination showed reddening, swelling, black discoloration, scaling, and variable-sized yellowish materials and edema in ear cross section. Microscopically, thrombosis, abscess, ulceration, epidermal hyperplasia, and dermal pyogranulomatous inflammation with an intralesional bacterial colony were observed. Staphylococcus hyicus was isolated in all pigs' ears and porcine reproductive and respiratory syndrome virus was detected by PCR and immunohistochemistry.
