The authors reviewed serial chest films of 113 patients of spontaneous pneumothorax which were treated byclosed tube thoracotomy during the period from May, 1979 till July, 1982 in CNUH. The resuls are as follows; 1.Male was more frequently affected than female, and the sex ratio was 3.5:1. 2. 71.1 per cent of patients were over31 years of age. 3. Of the 113 cases, 51.3 per cent were on the right, 48.7 per cent on the left. 4. The mostcommon underlying pulmonary disease was pulmonary tuberculosis(39.8), the next was belb or bullar (17.7%), and thelast was pneumonia(8.8%). 5. Pneumothorax was the most common type in pulmonary tuberculosis(66.7%), andpyopneumothorax in pneumonia(80.0%). 6. Among 103 cases in complete re-expansion of collapsed lung after closedthe thoracotomy, 39.5 per cent was expanded completely within 1 week in presence of visceral and/or parietalpleural thickening, and 86.2 per cent in none of it. According to the degree of pneumothorax, the more severedegree of pneumothorax, the more delay in re-expansion times. 7. Most common chest finding after re-expansion ofcollapsed lung was pleural thickening(51.4%).

The radiologic findings of lumbosacral spine and measurement of lumbosacral angle were analysed in 238 with backache and 102 without backache which were visited at Chungnam National University from March 1980 to July 1981.The measurement of lumbosacral angle was based on a method of Fergson. The results obtained were as follows; 1. The age group of 18 to 29 years was most common in backache group and the male was affected more frequently than the female with the ratio of 1.9 to 1. 2. In patients with backache, the overall mean lumbosacral angles were 44.2±2.6 degrees in male and 35.8±2.0 degrees in female. In patients without backache, in control group, the overall mean lumbosacral angles were 32.6±0.7 degrees in male and 33.4±1.4degrees in female. 3. In control group, difference of means between male and female was about 1degrees in patients with backache, the overall mean lumbosacral angles were increased about 12degrees in male and 2degrees in female than control group. In patients with and without backache, no significant difference of lumbosacral angle between the 4 age groups was present. 4. In backache group, increased lordosis was more common and increased lumbosacral angle than the decreased lordosis. 5. In backache group, lumbosacral angle of abnormal radiologic findings in lumbosacral spine was significantly increased than control group. 6. In patients with backache, radiologic findings and its lumboscral angles were alumbosacral anomaly 56 cases (23.5%): 46.9 degrees, increased lumbar lordosis 46 cases (19.2%): 48.1 degrees, osteoarthritis 44 cases(18.5%) : 40.8 degrees, decreased lumbar lordosis 30 cases (12.6%): 29.9 degrees, in order, And these radiologic findings were similar with many other authors.

BACKGROUND: Bronchoscopy is an essential procedure for identifying the bleeding site and evaluating cause of hemoptysis. However, it is controversial regarding to the timing of bronchoscopy in patients with hemoptysis. Early bronchoscopy, which was performed during hemoptysis or with 48hour after cessation of bleeding, was better for identifying the site of bleeding compared with delayed bronchoscopy, which was performed 48 hours after cessation of bleeding. The diagnostic yield of identifying the bleeding site by bronchoscopy was variable in reported literature and the safety of early bronchoscopy was not mentioned in previous literature. Therefore, we evaluated the efficacy and safety of early bronchoscopy in patients with hemoptysis. METHOD: From October 1994 to August 1996 in Samsung Medical Center, bronchoscopy was performed in patients with hemoptysis. Early bronchoscopy was performed prospectively during hemoptysis or within 48 hours after cessation of bleeding from May 1995 to August 1996. Delayed bronchoscopy group included patients who did not recieved early bronchoscopy at the same period or in whom bronchoscopy was performed 48 hour after cessation of bleeding from October 1994 to May 1995. RESULTS: Early bronchoscopy group was performed 73 times in 71 patients. Delayed bronchoscopy was performed in 57 times in 55 patients. There was no difference as to amount and underlying cause of hemoptysis between both groups. Indentification of bleeding site by visualizing active bleeding was significantly higher in early bronchoscopy(38.3%) than delayed bronchoscopy group (8.7%) (p<0.05). Indentification of bleeding site by bleeding after clot removal was 8 in early and 10 in delayed bronchoscopy. Indentification of bleeding site by visualizing active bleeding and bleeding after clot removal was 36 in early and 15 patients in delayed bronchoscopy(p>0.05). Causes of hemoptysis was found in 18 patients in early and 16 patients in delayed bronchoscopy group. patients who had early bronchoscopy underwent surgery. We diagnosed the site of bleeding in 4 patients preoperatively. In 3 patients we made a treatment plan promptly right after bronchoscopy. Among early bronchoscopy group, bleeding over 100cc during bronchoscopy occurred in 2 patients. In early bronchoscopy group there was no other major complication during bronchoscopy. CONCLUSION: In patients with hemoptysis, early bronchoscopy which performed within 48 hours after cessation of bleeding was more effective procedure for indentifying the bleeding site than delayed bronchoscopy which was performed after 48 hour cessation of bleeding.

OBJECTIVES: Although bronchoscopy is an important diagnostic tool for lung disease, patients compliance is low due to discomfort. Recently, midazolam which has a favorable anterograde amnesia effect and short action duration, has been used to relieve patients discomfort during bronchoscopy. Midazolam was investigated in order to see the beneficial effect and safety during bronchoscopy. METHODS: The study design was single blind, randomized, prospective. 102 patients were included, in whom bronchoscopy was performed between June, 19% and October, 1995 at Samsung Medical Center. They were categorized into midazolam group and control group. Patients were asked about the amnesic effect, discomfort of procedure and the willingness to repeat procedure. The consciousness level of patients during procedure, patient cooperation during procedure and ease of procedure were also reported by bronchoscopists. RESULTS: 1) The difference of oxygen saturation between two groups: There was no significant difference in oxygen saturation between midazolam group and control group before and after bronchoscopy. During procedure, however, mean oxygen saturations in midazolam group (90+/-6.4%) was significantly lower than in control group (93+/-4.7%)(p<0.05). 2) Evaluations by patients (1) Effect of amnesia: 41 patients (82%) in midazolam group could not recall the procedure but 52 patients (100%) recalled the entire procedure in control group. A favorable amnesic effects could be found in midazolam group(p<0.05). {2) The discomfort during the procedure: 43 patents(86%) did not experience discomfort from procedure in midazolam group but 25 patients(48%) complained of discomfort in control group (p<0.05). (3) Most patients except two(96%) were willing to repeat fiberoptic bronchoscopy in midazolam group but 13 patients (25%) answered that they would never repeat bronchoscapy. There was a statistically significant difference between two groups in the willingness to repeat bronchocopy (p<0.05). 3) The evaluations by bronchoscopists Cooperations of the patients and ease of procedure were not different between two groups. The patients in midazolam group except eight could not respond to verbal stimuli but most patients were awakened during procedure in control group(p<0.05). CONCLUSION: Midazolam is a good sedative agent for a patient to give a favorable amnesia, reduction of discomfort during bronchoscopy. We concluded that midazolam is a safe and useful sedative agent and midazolam may be used routinely during bronchoscopy. Monitoring of oxygen saturation, however, is essential to prevent severe hypoxia during procedure.

The leiomyoma of the bronchus is a very rare benign tumor in the lower respiratory tract. Though classical treatment of the branchial leiomyoma is surgical resection, bronchoscopic tumor resection has been recently applied to selected cases. We experienced two cases of bronchial leiomyomas which were successfully resected under flexible bronchoscopy using Nd-YAG laser and bronchial snare. We speculated that bronchoscopic resection of the bronchial leiomyoma would be an effective and safe way of treatment, and more technical developments should follow.

BACKGROUND: Rifampicin (RFP) is a key component of the antituberculous short-course chemotherapy and the RFP resistance is a marker of multi-drug resistant (MDR) tuberculosis. RpoB gene encodes the beta-subunit of RNA polymerase of M. tuberculosis which is the target of RFP. And the mutations of rpoB gene have been found in about 96% of rifampicin resistant clinical isolates of M. tuberculosis. So in order to find a rapid and clinically useful diagnostic method in identifying the REP resistance, we compared the PCR-line probe method with PCR-SSCP for the detection of the rpoB gene mutation in cultured M. tuberculosis. METHODS: 45 clinical isoLates were collected from patients who visited Sung Kyun Kwan University Hospital. The REP susceptibility test was referred to the referral laboratory of the Korean Tuberculosis Institute. 33 were rifampicin resistant and 12 were rifampicin susceptible. The susceptibility results were compared with the results of the PCR-SSCF and PCR-line probe method. RESULTS: We could find rpoB mutations in 27/33(81.8%) RFP-resistant strains by PCR-line probe method, and in 23/33(69.7%) by PCR-SSCP and there was no significant difference between two methods. There was no mutation in rifampicinn susceptible strains by both methods.: Comparison of PCR-line probe and PCR-SSCP methods for detection rifampicin resistance CONCLUSION: PCR-Iine probe method would be a rapid, sensitive and specific method for the detection of rifampicin resistant Mycobacterium tuberculosis.
