We hereby report a case on bronchogenic cyst which is initially non-infected, then becomes infected after bronchoscopic ultrasound (US)-guided transesophageal fine-needle aspiration (FNA). The non-infected bronchogenic cyst appears to be filled with relatively echogenic materials on US, and the aspirate is a whitish jelly-like fluid. Upon contrast-enhanced MRI of the infected bronchogenic cyst, a T1-weighted image shows low signal intensity and a T2-weighted image shows high signal intensity, with no enhancements of the cyst contents, but enhancements of the thickened cystic wall. The patient then undergo video-assisted thoracic surgery 14 days after the FNA. The cystic mass is known to be completely removed, and the aspirate is yellowish and purulent. To understand the image findings that pertain to the gross appearance of the cyst contents will help to diagnose bronchogenic cysts in the future.

Background and Objectives: Most of tracheal stenosis is resulted from longstanding endotracheal tube insertion. Treatments of tracheal stenosis are divided conservative and reconstructive treatment. The propose of this study was to evaluate the effect of prosthetic tracheal T-tube insertion on tracheal stenostic patients who can not be operated invasive surgery. Subjects and Method : Nine prosthetic tracheal T-tube insertion were studied from 9 patients from January 2002 to April 2007. The effect of silastic T-tube was analyzed according to the factors that were respiratory difficulty, oxygen saturation, phonation, aspiration and significant complications. Results: Four patients were good for respiration and no complication. But five patients occur various complications. A successful group did not have cartilagenous lesions but failed group had catilagenous lesions, infection and necrosis. Conclusion: A silastic T-tube insertion was good for palliative treatment in patients without catilagenous lesions.

As of today, the frequency of primary lung cancer is one of the improved problems in modern medicine and is increasing rapidly year by year. This study dealed with 138 cases of primary lung cancer proved by histopathologic examination in Thoracic & Card iovascular Surgery Dept. of N.M.C. from Sept. 1966 through June 1981. The majority of patients belong to 5th and 6th decade. Ratio between male and female was 3.7: 1. Initial symptoms were cough, blood tinged sputum, hemoptysis, chest pain, dyspnea and duration of symptoms before admission was within 6 months [60%] and 12 months [78%]. Histopathologically, 64 cases [61%] of them were the squamous cell carcinoma, 21 cases [15%] were the adenocarcinoma, 20 cases [14.8%] were the anaplastic carcinoma. Fifty-six cases were resectable: 43 cases were subjected to pneumonectomy and 13 cases were to lobectomy. The remaining 82 cases were nonresectable, but exploratory thoracotomy was performed in 22 cases of them. Among 56 resected cases, 33 cases were radically operated and 17 cases were subjected to palliative operation and 6 cases were subjected to extended operation. [Concomitant pericardium resection in 1 case and concomitant chest wall resection in 5 cases]. Surgical mortality was 10.7% and causes of death were aspiration of contralateral lung, respiratory insufficiency, postop. empyema with B.P.F, cardiogenic failure. This study analysed the cancer stage between preop clinical T.N.M. stage and postop. T.N.M. stage in 78 cases; resectable 56 cases and non-resectable 22 cases.

Open lung biopsy still has important roles for the marking of diagnosis of diffuse infiltrative lung disease even though transbronchial bronchoscopic lung biopsy and percutaneous needle aspiration biopsy gain popularity nowadays. This is clinical retrospective review of the 56 patients with diffuse infiltrative lung disease undergoing open lung biopsy by minithoracotomy from 1984 to Dec. 1992 in the Department of Thoracic & Cardiovascular Surgery of Catholic University Medical College. 27 men and 29 women, aged 17 to 73 year [mean 49 year , were enrolled & divided into 2 groups;Group A consisted of patients with immunocompromised state [n=19 , Group B patients with non-immunocompromised state[n=38 . Pathologic diagnosis was made in 54 cases[96.4% of these two groups and as follows: infectious; 12 patients[21.4% , Neoplastic; 10 patients[17.9% , granulomatous; 4 patients[7.1% , interstitial pneumonia; 12 patients[21.4% , Pulmonary fibrosis; 8 patients[14.3% , others; 3 patients[5.4% , nonspecific; 5 patients[8.9% , and undetermined; 2 patients[3.6% . Therapeutic plans were changed in 39 patients[69.6% after taking of tissue diagnosis by open lung biopsy. Group B has higher incidence of infectious diseases and change of therapeutic plan than the Group A. The postoperative complications developed in 8 cases[14.3% ,and there is no difference of incidence between the 2 groups. 4 patients belongs to group A, died of respiratory distress syndrome [2 and sepsis [2 which were not related with open lung biopsy procedure. In conclusion, open lung biopsy is a reliable method to obtain a diagnosis in diffuse pulmonary infiltrates and can be performed safely, even in acutely ill, immunosuppressed patients.

An electromyographic device was used to investigate the relationship between a linguistic hypothesis of tense-lax distinction and muscular activity. Muscle action potentials of the orbicularis oris muscle and the depressor anguli oris muscle were obtained from four subjects using CVCVCV and CVCVC words in English and VCV and CVC words in Korean. Findings: The hypothesis that the speaker may select at least one of muscles involved in the articulation of a phoneme so that the selected muscle could be activated for tense-lax distinction, and either a timing variable or an amplitude variablethe and/or both from the selected muscle distinguish(es) /p/ from /b/ in English and /$p^{h},\;p^{l}$/ from /p/ in Korean, with the English /p/ and the Korean /$p^{h},\;p^{l}$/ being tense, and the Korean unaspirated /p/ and the English /b/ lax, has been verified, except for the case with subject 2 in stressed syllables in English. (2) Thus, the linguistic hypothesis of tense-lax distinction was strongly supported by the muscular activities during the Korean bilabial stops, with /$p^{h}\;and\;p^{l}$/ being tense and /p/ lax. (3) Considering the intermuscle compensation and the interspeaker variabilities in the choice of a muscle or muscles, in English the usability of the feature 'tensity' appeared to be positive rather than negative although further investigations with more subjects remain to take on the muscles associated with the onset/offset of the labial closure, including the respiratory muscles related with the aspiration. The phoneme-sensitive EMG manifestations of stress and possible reasons for the interspeaker variabilities are discussed.

We observed 56 cases of nontraumatic pneumothorax clinically and statistically, which had been experienced at the deparment of chest surgery. St. Mary`s Hospital,Catholic Medical College in theserecent years. 1] In the underlying pathology of spontaneous pneumothorax, nontuberculous origin [60.7%], especially due to pulmonary emphysema or blebs[17.8%], especially due to pulmonary emphysema or blebs[17. 8%], tended to increase as the reports of foreign countries, but tuberculous origin was still high in our country[39.3%]. Considering the 14 cases, unknown underlying pathology, the most of them might have scattered blebs which were not revealed in chest Roentgen films. 2] The principle treatment done in our clinic was as follows; The patients, below 20% lung collapse were treated by bed rest and abdominal respiration. The patients, between 20% and 40% lung collapse were treated by repeated pleural aspiration or closed thoracotomy followed. The cases,over 40% lung collapse were treated by closed thoracotomy initially. 3] The average duration of indweIling catheter was 3 to 4 days in the closed thoracotomy. We used to not remove the indwelling catheter early to promote pleural adhesion. 4] Sometimes, the closed thoracotomy drainage induces bronchial irritation and asthmatic attacks, especially in old age group accompanying pulmonary emphysema. In these cases, respiratory difficulties and acidosis should be prevented and controlled with medical treatment including steroid therapy.
