Background : The prevalence of pulmonary tuberculosis among the elderly is increasing in Korea and in the developed countries due to the increased elderly population and their predispositions to chronic disease, poverty and decreased immunity. To define the characteristics of pulmonary tuberculosis in the elderly, we evaluated the clinical spectrum of pulmonary tuberculosis. Method : We analyzed 92 patients retrospectively that were diagnosed as active pulmonary tuberculosis over the age of 65. The analysis involved patient's profiles, clinical manifestations, coexisting diseases, diagnostic methods, anti-TB medications and their side effects, and treatment outcomes. Results : The results were as follows : - 1) The ratio of male to female was 2.1:1(62:30 cases) 2) Chief complaints were a cough (47.8%), dyspnea (40.2%), sputum (38.0%), chest pain (12.0%), anorexia (10.9%), and fever (9.8%). 3) 38 (41.3%) of cases had a past history of pulmonary tuberculosis. 4) The coexisting diseases were : -COPD, 25 cases (27.2%); pneumonia, 17 cases (18.5%); DM. 13 cases (14.1%); and malignancy, 10 cases (10.9%). 5) The positivity of Mantoux test (5 TU, PPD-S) was 82.7%. 6) Pulmonary tuberculosis was diagnosed using the following methods : sputum AFB (Acid Fast Bacillus) smear 42.4%, sputum TB (M. Tuberculosis) culture 15.2%, sputum TB PCR (Polymerase Chain Reaction) 10.9%, bronchial washing AFB smear 2.1%, chest radiology only 25.0%. 7) Locations of radiologic lesions were RULF, 50 cases; RLLF, 50 cases, mostly, then LLLF ; 26 cases were leastly involved. 8) The coexisting tuberculosis were endobronchial TB(8.7%), TB pleurisy(7.6%) miliary TB(5.4%), intestinal TB(2.2%), renal TB(1.1%) 9) The proportion of treatment regimen with 1st line drug and 2nd line drug were 92.3% and 7.6%, respectively. 10) The outcome of treatment were as follows : cured 31.5%, expired 13.0%, no return 47.8%, follow-up now 7.6%. Conclusion : The pulmonary tuberculosis in the elderly has atypical patterns with chronic coexisting diseases. Therefore, the possibility of pulmonary tuberculosis should be considered in elderly patients with pulmonary symptoms.

Recently, primary lung cancer has increased markedly in incidence & prevalence in korea. Prom July 1979 to June 1996, 183 patients were diagnosed and operated for primary non-small cell lung cancer, and evaluated clinically. 1. There were 164 males and 19 females(M:P=8.6: 1), and the peak incidence of age was 50th and 60th decade of life(73.7%). 2. Most of symptoms were respiratory, whitch were cough(44.8%), chest pain(30.1%), dyspnea(20.8%), hemoptysis or blood tinged sputum(19.7%), sputum(15.3%), and asymptomatic cases were 12.0%. 3. Histopathologically, sguamous cell carcinoma was 68.9%, adenocarcinoma 19.7%, bronchioloalveol r cell carcinoma 2.2%, adenosguamous cell carcinoma 1.6%, and large cell carcinoma 7.7%. 4. In the operation, pneumonectomy was 41.0%, lobectomy 42.1%, bilobectomy 13.1%, stagmentectomy or wedge resection 1.6%, and explore tharacotomy 2.2%, and the overall resectability was 97.8%. 5. Postoperative complications were developed in 31.9%, and operative mortality was 1.6%. 6. In postoperative stagings, stage I was 38.3%, stage H 14.8%, stage llla 31.1%, and stage IIIb 15.8%. 7. The overall cumulative survival rates were 1 year 77.8%, 3 year 42.7%, and 5 year 39.5%. The 5 year survival rate according to stage were stage 153.0%, stage H 46.5%, stage I[la 28.2%, and stage IIIb 13.8%(p<0.05), according to operation method were lobectomy 45.0%, and pneumonectomy 30.3%(p<0.05), and according to mediastinal involvement were Nl 32.0%, and N2 11.1%(p<0.05). The 5 year survival rate according to histologic type were squamous cell carcinoma 43.1%, adenocarcinoma 23.3%, and large cell carcinoma 30.3 (p>0.05).

Purpose : The aim of this study is to evaluate the value of lung biopsies for the management of children with lung disease. Methods : We retrospectively reviewed 19 lung biopsies done at Asan Medical Center, Seoul between 1993 and 2001. Data gathered included demographic information, underlying conditions, diagnosis before biopsy, final diagnosis, change in therapy, morbidity and mortality. Results : Nineteen patients underwent lung biopsy. Among them, 13 patients were male and six patients were female; the median age was 3.6 years(0.8 to 8.6 years). Twelve patients underwent open lung biopsies and seven patients had thoracoscopic biopsies. The overall diagnosis rate was 95 %. The most common diagnosis was interstitial lung disease(12 patients, 64%) and infection was detected in four patients(21%). The biopsy-proven bronchiolitis obliterance was confirmed in two of seven patients suspected by CT findings. Specific treatment was changed after biopsy in 16 patients (85%). The morbidity & overall mortality rates of the patients were 5%(one patient) and 21%(four patients) respectively. Only one complication was seen : empyema. The causes of death were acute respiratory distress syndrome(one patient), respiratory failure(two patients), and septicemia(one patient). Conclusion : The lung biopsy is a safe procedure and it contributes to more accurate diagnosis and proper management of pediatric lung diseases. We recommend lung biopsies should be considered more positively in the diagnosis of pediatric lung diseases.
