It has been widely accepted that the detachable balloon catheter technique is the treatement of choice in thecarotid-cavernous fistula and in the unclippable giant aneurysm at the cavernous or petrous portion of theinternal carotid artery. The authors successfully treated one case of the carotid-carvernous fistula and one caseof giant aneurys, located in petrous portion of the internal carotid artery using Debrun's latex datachableballoon catheter technique. In thecase with carotid-cavernous fistula, the only fistula was occluded with adetachable balloon, presserving the intrenal carotid artery. In the aneurysm case, both internal carotid arteryand aneurysm itself were completely occluded with 3 latex detachable balloons. Both patients have nocomplications. The authors will describe and discuss the Debrun's latex detachable balloon catheter technique.

Pseudomembranous colitis, although uncommon, is an important complication of antibiotics that is related to a variety of deleterious effects on the gastrointestinal tract. Rifampicin is one of the 1st line agents in the treatment of tuberculosis and a large number of patients are exposed to its potential adverse effects. We report upon a patient that had diarrhea due to pseudomembranous colitis after receiving antitubeculous medication, and which was probably caused by rifampicin. A 77-year-old man was admitted with diarrhea of three weeks duration. One month previously, he suffered from left pleuritic chest pain and left pleural effusion was noticed at chest X-ray. One week prior to the onset of diarrhea, he was started on empirically isoniazid, rifampicin, ethambutol and pyrazynamide as antituberculous medication. On admission, he complained of diarrhea, left pleuritic chest pain, dyspnea and sputum. On physical examination, breathing sound was decreased in the left lower lung field and bowel sound increased. Pleural biopsy revealed chronic granulomatous infalmmation, which was compatible with tuberculosis. Sigmoidoscopy showed whitish to yellowish pseudomembrane with intervening normal mucosa, and his stool was positive for C.difficle toxin. He was diagnosed as pseudomembranous colitis and treated with oral metronidazole and vancomycin. The diarrhea did not recur after reinstitution of the anti-tuberculous medication without rifampicin. In patients with severe diarrhea receining anti-tuberculous medication, rifampicin induced pseudomembranous colitis should be excluded.

BACKGROUND: Diffuse alveolar hemorrhage (DAH) is rare but often fatal. To determine the clinical manifestations of DAH, its etiology, clinical course and prognosis were studied. METHODS: A retrospective analysis was performed in 21 patients that were diagnosed as DAH. Diagnosis of DAH was based on the presence of the "classical triad" of hemoptysis, anemia, and rapidly progressive infiltrates on chest X-ray and a finding of bronchoalveloar lavage or lung biopsy. RESULTS: Thirteen patients (61.9%) had collagen vascular diseases (CVDs) as underlying disease and 10 patients had systemic lupus erythematosus. Females were more prevalent in CVD than in non-collagen vascular disease (NCVD). Otherwise, there were no significant differences between the two groups in terms of clinical manifestations. Dyspnea (95.2%), cough (76.2%), hemoptysis (61.9%), and fever (33.0%) were frequent symptoms. The initial creatinine level was higher in CVD than in NCVD (3.27±3.15 mg/dl vs. 1.19±0.94 md/dl, p=0.030). The corresponding drop in hemoglobin level was 2.69±1.26 g/dl. Maximal drop in hemoglobin preceded the progression of infiltrates on the chest radiograph by 1.38±4.22 days. The mortality rate was higher in the patients with NCVD than in those with CVD (50.0% vs. 23.1%). CONCLUSION: The DAH can occur not only in patients with CVD but also in those with NCVD. Higher creatinine level CVD in patients is associated with renal involvement in conjunction with DAH. The maximal drop in hemoglobin preceeding the progression of infiltrates on the chest radiograph suggests that the drop in hemoglobin is important for diagnosing DAH.

Catamenial hemoptysis is a rare condition caused by thoracic endometriosis that presents as tracheobronchial or pulmonary endometriosis. While hormonal treatment may cause virilization and sterility, due to the antiestrogenic effect, its surgical removal via thoracotomy is a particularly invasive procedure and is not recommended as the first choice treatment in young woman. Successful surgical removal by video-assisted thoracoscopic surgery (VATS) has recently been reported, and may be indicated for young patients who at some stage would like to become pregnant. Herein, a case of a 25-year-old unmarried woman with catamenial hemoptysis, cured by VATS, is reported.

BACKGROUND: We studied the clinical significance of nontuberculous mycobacteria (NTM) recovered from respiratory specimens for six months in a tertiary referral center. METHODS: We identified all NTM isolates from sputum or bronchial washing from October, 2001 to March, 2002, using polymerase chain reaction-restriction fragment length polymorphism analysis method amplifying the rpoB gene. Patients were classified as having definite, probable, or unlikely NTM disease as defined by the American Thoracic Society and the British Thoracic Society guidelines. RESULTS: 261 isolates of NTM recovered from 162 patients. In 162 patients, M. avium complex (MAC) was the most common species comprising 29.6% (n=48), which was followed by M. fortuitum complex (n=46, 28.4%), M. abscessus (n=26, 16.0%). 29 (17.9%) patients had definite NTM disease, and 13 (8.0%) had probable NTM disease. The common organisms involved in NTM diseases were MAC (n=23, 54.8%), M. abscessus (n=12, 28.6%). In a univariate analysis, predictive factors that were related to NTM disease were BMI <18.5 kg/m2, presence of symptoms, previous history of antituberculous treatment, positive sputum smear, presence of infiltrative, nodular or cavitary lesions at chest radiography, and isolation of MAC or M. abscessus. In a multivariate analysis, isolation of MAC or M. abscessus (OR 16.3, 95% CI 4.2~62.7, p<0.001), cavity at chest radiography (OR 4.8, 95% CI 1.4~16.6, p=0.012), and positive sputum smear (OR 4.3, 95% CI 1.4~13.3, p=0.012) were found to be variables independently associated with pulmonary disease. CONCLSUION: Epidemiology of NTM pulmonary disease in Korea is different from that in other countries. A high index of clinical suspicion as well as an accurate identification of the isolates would be required for the diagnosis of NTM pulmonary disease.

BACKGROUND: Five year survival rate of postoperative stage I non-small lung cancer(NSCLC) reaches to 66%. In the remaining one third of patients, however, cancer recurs and overall survival of NSCLC remains dismal. To evaluate clinical and pathologic characteristics of recurred NSCLC, we studied patterns and factors for postoperative recurrence in patients with staged I, II NSCLC. METHOD: A retrospective analysis was performed in 234 patients who underwent radical resection for pathologic stage I, II NSCLC. All patients followed for at least one year were included in this study. RESULTS: 1) There were 177 men and 57 women. The median age was 63. The median duration of follow up was 732 days (range 365~1,695 days). The overall recurrence rate was 26.5% and the recurrence occurred at 358.8 +/- 239.8 days after operation. 2) The age of recurred NSCLC patients were higher (63.2 +/- 8.8 years) than that of non-recurred patients (60.3 +/- 9.8 years)(p=0.043). The recurrence rate was higher in stage II (46.9%) than in stage I (18.8%, p<0.001) NSCLC. The size of primary lung mass was larger in recurred (5.45 +/- 3.22 cm) than that of non-recurred NSCLC (3.74 +/- 1.75 cm, p<0.001). Interestingly, there were no recurrent cases when the resected primary tumors were less than 2cm. 3) Distant recurrence was more frequent than locoregional recurrence (66.1% vs. 33.9%). Distant recurrence rate was more frequent in female and adenocarcinoma. Brain metastasis was more frequent in patients with adenocarcinoma than squamous cell carcinoma (p=0.024). CONCLUSION: The tumor size and stage were two important factors for recurrence. Considering that distant brain metastasis was more frequent in patients with adenocarinoma, prospective study should follow to evaluate the effectiveness of preoperative brain imaging.

BACKGROUND: The melanoma antigen-encoding (MAGE) genes are known to be expressed in various cancer cells, including non-small cell lung cancer (NSCLC), and are silent in all normal tissues except for the testis. In patients with peripheral NSCLC, bronchial washing fluid can be used to detect the MAGE genes, suggesting a diagnosis of lung cancer. In order to evaluate the diagnostic utility of the MAGE test in patients with peripheral NSCLC, bronchial washing fluid was investigated in patients with peripheral pulmonary nodules, which were invisible as detected by bronchoscopy. METHODS: Bronchial washing fluid from 37 patients was used for cytological examinations and MAGE gene detection, using RT-nested-PCR of common A1-A6 mRNA. Results were compared to a final diagnosis of patients as confirmed by pathology. RESULTS: Among the 37 subjects, NSCLC was diagnosed in 21 patients, and benign pulmonary diseases were diagnosed in 16 patients. MAGE mRNA was detected in 10 of 21 (47.6%) NSCLC patients, while conventional cytology examinations were positive for MAGE expression in 2 of 21 (9.5%) cases. MAGE expression was observed in 4 of 16 (25%) benign pulmonary disease patients. CONCLUSION: The MAGE test of bronchial washing fluid can be used as a sensitive predictor of peripheral NSCLC patients.

This study was conducted to evaluate the effectiveness and safety of a practical protocol for titrating positive end-expiratory pressure (PEEP) involving recruitment maneuver (RM) and decremental PEEP. Seventeen consecutive patients with acute lung injury who underwent PEEP titration were included in the analysis. After baseline ventilation, RM (continuous positive airway pressure, 35 cm H2O for 45 sec) was performed and PEEP was increased to 20 cmH2O or the highest PEEP guaranteeing the minimal tidal volume of 5 mL/kg. Then PEEP was decreased every 20 min in 2 cmH2O decrements. The "optimal" PEEP was defined as the lowest PEEP attainable without causing a significant drop (>10%) in PaO2. The "optimal PEEP" was 14.5 +/- 3.8 cmH2O. PaO2 /FI O2 ratio was 154.8 +/- 63.3 mmHg at baseline and improved to 290.0 +/- 96.4 mmHg at highest PEEP and 302.7 +/- 94.2 mmHg at "optimal PEEP", both significantly higher than baseline (p<0.05). Static compliance was significantly higher at "optimal" PEEP (27.2 +/- 10.4 mL/ cmH2O) compared to highest PEEP (22.3 +/- 7.7 mL/cmH2O) (p<0.05). Three patients experienced transient hypotension and one patient experienced atrial premature contractions. No patient had gross barotrauma. PEEP titration protocol involving RM and PEEP decrement was effective in improving oxygenation and was generally welltolerated.

BACKGROUND: Extubation failure was associated with poor prognosis and high hospital mortality. Cuff leak test (CLT) has been proposed as a relatively simple method for detecting laryngeal obstruction that predispose toward postextubation stridor (PES) and reintubation. We examined the risk factors of extubation failure and evaluated the usefulness and limitation of CLT for predicting PES and reintubation. METHODS: Thirty-four consecutive patients intubated more than 24 hours were examined. The subjects were evaluated daily for extubation readiness, and CLT was performed prior to extubation. Several parameters in the extubation success and failure group were compared. The accuracy and limitation of CLT were evaluated after choosing the thresholds values of the cuff leak volume (CLV) and percentage (CLP). RESULTS: Of the 34 patients studied, 6 (17.6%) developed extubation failure and 3 (8.8%) were accompanied by PES. The patients who had extubation failure were more likely to have a longer duration of intubation and more severe illness. The patients who developed PES had a smaller cuff leak than the others: according to the CLV (22.5+/-23.8 vs 233.3+/-147.1ml, p=0.020) or CLP (6.2+/-7.3 vs 44.3+/-24.7%, p=0.013). The best cut off values for the CLV and CLP were 50ml and 14.7%, respectively. The sensitivity, negative predictive value, and specificity of CLT were relatively high, but the positive predictive value was low. CONCLUSION: The likelihood of developing extubation failure increases with increasing severity of illness and duration of intubation. A low CLV or CLP (<50ml or 14.7%) is useful in identifying patients at risk of PES, but the CLT is not an absolute predictor and should not be used an indicator for delaying extubation.
