ABSTRACT
Pulmonary siderosis is one kind of pneumoconiosis caused by the long term inhalation of iron dust. Iron is deposited in the lungs, usually in the form of iron oxides. Iron oxides are relatively inert particles with a minimal fibrotic response. It occurs in a number of occupations including welding, steel rolling and grinding, casting, iron ore mining and oxyacetylene cutters. We have experienced the first case of pulmonary siderosis in Korea. A 42-year-old woman who had engaged in a metalware manufacturing factory as a manager for 7 years was admitted because of dyspnea on exertion. A pulmonary function test disclosed a mildly obstructive ventilatory defect. Open lung biosy revealed deposition of iron-laden macrophages in most alveolar spaces by which confirmed the diagnosis of pulmonary siderosis. We report a case of pulmonary siderosis with a review of the literature.

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.

BACKGROUND: Although pulmonary tuberculosis is effectively controlled with 6 months or 9 months short course standard regimens, comparable numbers of treatment failures ensued because of inadequate treatment mainly due to patient's poor compliance. Indequate treatment with standard regimens during initial treatment may cause emergence of drug resistance and prolong the duration of chemotherapy. Also it may make the patient lesser compliant and finally increase the morbidity and the mortality. METHODS: A clinical study was done to evaluate clinical and bacteriological characteristics of 94 patients who were retreated for pulmonary tuberculosis. RESULTS: 1) 62 of the 94 patients were male and 32 patients were female. Mean age is 51 years old in male and 45 years old in female. 2) The extent of the disease on the chest radiograph was minimal in 10(11.1%) patients, moderate in 31(33.3%) patients, and far advanced in 52(55.6%) patients. 3) On sputum bacteriologic examination, 73(77.7%) patients were positive in sputum AFB smear and/or culture for Mycobacterium tuberculosis. 4) Results of drug sensitivity test performed in 42 patients showed that the resistance to one drug is in 9(20.5%) patients, two drugs in 18(40.8%) patients, and more than three drugs in 14(31.8%) patients. 5) Poor patient's compliance was the leading cause of the retreatment of pulmonary tuberculosis (43.6%) 6) Only 24(25.5%) patients of the 94 retreatment patients were successfully treated and 39 (41.6%) patients were dropped out during follow-up. CONCLUSION: We concluded that poor patient's compliance was the most important cause of treatment failure not only in primary treatment patients but also in retreatment patients. Primary treatment of pulmonary tuberculosis should be completed under strict monitoring of the patient because significant number of retreatment patients had multiple drug resistance and poor outcome.

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.

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.
