BACKGROUND: Hemoptysis is a common clinical symptom, responsible for 11% of admission to the hospital chest service. Correct diagnosis, accurate localization of the bleeding source and proper management are imperative to reduce the risk of massive hemoptysis. We performed the study to define the optimal time of fiberoptic bronchoscopy in 63 patients with hemoptysis admitted to Kyung Hee University Hospital between Aug 1989 and Aug1992. METHODS: Retrospective analysis of medical records concerning the cause, amount, duration of hemoptysis and the timing of fiberoptic bronchoscopy in 63(M:F=36:27) patients. RESULTS: 1) The main causes of hemoptysis were pulmonary tuberculosis(52.4%) bronchiectasis(27.0%) and lung cancer(11.1%). 2) The bleeding sites were localized in 26 Patients(41.3%). 3) The rates of localization of bleeding site were not related to the amount and duration of hemoptysis. 4) The rates of localization of bleeding site were 61.8%(21/34) during hemoptysis,18.2%(122) within 24hr after resolution of hemoptysis, 14.3%(1/7) thereafter. CONCLUSION: Early bronchoscopy, especially during hemoptysis may show higher rates of successful localization than delayed bronchoscopy.

"It was reported that polymorphism of TNF alpha gene was present in promoter region and involves the substitution of guanine by adenosine in the uncommon (TNFA 2) allele. In this study, we investigated the significance of TNFA gene polymorphism in relation to various clinical characteristics and autoantibody profiles in SLE as well as comparing it with that of other countries, and also studied its association with peripheral TNF-a production in vitro. TNFA genotyping was performed in 126 SLE patients and 300 controls using DNA extracted from peripheral leucocytes. The biallelic polymorphism at position -308 of the TNFA promotor was determined by Ncol- RFLP. Peripheral mononuclear cell production of TNF-a was investigated by bioassay using L-929 cell cytotoxicity. The TNFA ""1 homozygote was a predominant allele (77.0%) in SLE, which was not different from the controls. TNFA ""2 homozygate was extremely rare in both patients and controls (0.8%, 1.3% respectively). The clinical manifestations between TNFA '1 and TNFA""2 did not differ. The production of autoantibodies including dsDNA, anti-La, anti-nRNP and anti-Sm was not different between two alleles, whereas anti- Ro antibody was more frequent in TNFA""1/TNFA '1 than in TNFA'1/TNFA'2 (62.1% vs 38.4%, P=0.022). The polymorphism of TNFA gene did not influence the lipopolysaccharide stimulated peripheral mononuclear cell production of TNF-a (1356+/-293 vs 1119+/-385 pg/ml; TNFA'1/TNFA'1, TNFA'1/TNFA'2 respectively). These results suggested that promoter polymorphism of TNFA was not directly involved in the susceptibility of SLE and was not responsible for differential peripheral TNF-a production, but TNFA ' may be associated with anti-Ro antibody production."

BACKGROUND: Transthoracic fine needle aspiration and biopsy(TNAB) has become a frequently used technique in the investigation of the intrathoracic lesions because of its safety, reliability, and accuracy. METHOD: Data on 125 patients who underwent TNAB from 1990 through 1994 were studied to determine the diagnostic sensitivity, accuracy and complications of this procedure as related to lesion type and location. RESULTS: 1. The over-all diagnostic sensitivity of TNAB was 61.6%(77 of 125 patients). 2. The diagnostic yields were as high as 89.9% for malignant lesions, but a specific diagnosis of benign lesions were obtained only in 30% of benign lung lesions. 3. The correlation between results of TNAB cytology and of final histology was as high as 88.2%. 4. Lung lesions that were greater than 3cm in size had a higher proportion of correct diagnosis(73.3%) as compared with lesions 3cm or less in size(38.1%). But there was no significant difference between the central and peripheral lung lesions. 5. There were no serious complications to TNAB. In 12.8% of the procedures a pneumothorax developed, indicating a chest tube in 1.6% of the procedures. In 2 cases, minimal hemoptysis developed which did not require treatment. CONCLUSION: In our experience, TNAB represents a minor and safe procedure, which permits a direct approach to localized malignant lung lesions with a high degree of accuracy.

Pulmonary involvement of salmonella infection is very rare and only one case of salmonella empyema had been reported in Korea. A 53-year-old woman presented to Kyung Hee Medical Center with 2-months history of left chest pain and mild fever. 3 months prior to admission, the patient was taken to laparoscopic laser cholecystectomy due to gall stone in other hospital. Chest X-ray taken on admission day showed pneumonic infiltration at left lower lung field with pleural effusion. Salmonella Group B was identified from the cultures of stool, blood, and pleural fluid. After consecutive therapy with two weeks of ceftriaxone and three weeks of ciprofloxacin combined with repeated pleural aspirations, the patient was recovered and discharged. But she was readmitted two months later due to fever and generalized malaise. The result of blood culture showed growth of Salminella Group B. The excisional biopsy of right supraclavicular lymph node disclosed necrotizing lymphadenitis. She was recovered clinically and no more bacteremia occurred after two weeks of ciprofloxacin therapy. We present very rare case of empyema due to salmonella infection and review the pertinent literature.
