Background: Miliary tuberculosis almost always results from the discharge of infected caseous material into the blood stream, usually from a well hidden lymph node in the presentation of this disease in the past four decades, and although it is seen less frequent1y today than previously, its presentation and manifestation may require greater suspicion and diligence by the physician. We investigated the clinical characteristics, predisposing factors and accompanying diseases of miliary tuberculosis and tried to acquire the early diagnosis and treatment of this disease. Methods: A retrospective clinical study was done on 40 cases of miliary tuberculosis admitted to Hanyang University Hospital from Mar. 1989 to Dec.1992. The study investigated age and sex distribution, seasonal distribution, duration of symptoms before admission, pre-disposing factors, clinical symptoms, biochemical findings, chest X-ray findings, extrapulmonary tuberculosis associated with miliary tuberculosis, prognosis and mortality rate. Results: 1) The patients were most common in the age group between 20 and 29(23%) and the ratio of male to female was 1.4:1(male 23 : female 17). 2) Sputum smears for tubercle bacilli were positive in 5 cases(13%). 3) The most common clinical symptoms were fever with chilling(47.5%), coughing(47.5%), second most common symptom was dyspnea(32.5%), and the physical findings on admission were tachycardia(30%), weight loss(27.5%), meningeal signs(17.5%) in order. 4) The predisposing factors were heavy alcohol drinking(6 cases), steroid use(3 cases), pregnancy(2 cases) etc. 5) The chest X-ray findings on admission were miliary shadow only(40%), in addition pneumonic infiltration, pleurisy, and calcification in order. 6) The extrapulmonary tuberculosis associated with miliary tuberculosis were tuberculous meningitis(30%), bone and joint tuberculosis(17.5%), intestinal tuberculosis(15%) in order. 7) Biochemical findings were increased SGOT/SGPT(32.5%), increased alkaline phosphatase(32.5%), hypoalbuminemia(15%), hyponatremia(15%) etc. 8) About 4-6 weeks later after treatment(INH, RFP, PZA, EMB), 26 cases(65%) were improved on clinical symptoms or chest X-ray, 12 cases(30%) were stationary or aggravated, and 2 cases(5%) were died. Conclusion: For the early diagnosis and treatment of miliary tuberculosis, we must see its presentation and manifestation with greater interest and suspicion and investigate its predisposing factors and accompanying diseases.

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.

Background : Recent outbreaks of pulmonary disease due to drug-resistant strains of Mycobacterium Tuberculosis have resulted in significant morbidity and mortality in patients worldwide. We reviewed our experience to evaluate the effects of pulmonary resection on the management of multidrug-resistant tuberculosis. Method : A retrospective review was performed of 41 patients undergoing pulmonary resection for multidrug-resistant tuberculosis between January 1993 and December 1997. We divided these into 3 groups according to the radiologic findings : (1) patients who have reasonably localized lesion (Localized Lesion Group ; LLG) (2) patients who have cavitary lesions after pulmonary resection on chest roentgenogram (Remained Cavity Group : RCG) (3) patients who have Remained infiltrative lesions postoperatively (Remained infiltrative group : RIG). We evaluated the negative conversion rate after resection and overall response rate of the groups. Then they were compared with the results of the chemotherapy on the multi drug-resistant tuberculosis which has been outcome by Goble et al. Goble et al reported that negative conversion rate was 65% and overall response rate, 56% over a mean period of 5.1 months. Results : Seventy five point six percent were men and 24.4% women with a median age of 31 years (range, 16 to 60 years). Although the patients were treated preoperatively with multidrug regimens in an effort to reduce the mycobacterial burden, 22 of 41 were still sputum culture positive at the time of surgery. 20 of 22 patients(90.9%, p<0.01) responded which is defined as negative sputum cultures within 2 months postoperative. Of 26 patients with the sufficient follow up data, 19 have Remained sputum culture negative for a mean duration of 25.7 months (73.1%, p<0.05). The bulk of the disease was manifest in one lung, but lesser amounts of contralateral disease were demonstrated in 15, consisted of 8 in RIG and 7 in RCG, of 41. 12 of 12 patients (100%, p<0.01) who were sputum positive at the time of surgery in LLG converted successfully. 14 of 15 patients (93.3%, p<0.05) with the follow up have completed treatment and not relapsed for a mean period of 25. 7 months. The mean length of postoperative drug therapy of LLG was 12.2 months. In RIG, postoperative negative conversion rate was 83.3% which was not significant statistically. There was a statistical significance in overall response rate (100%, p<0.05) of RIG for a mean period of 24.4 months with a mean length of postoperative chemotherapy, 11.8 months. In RCG a statistically lower overall response rate (14.3%, p<0.01) has been revealed for a mean duration of follow up, 24.2 months. A negative conversion rate of RCG was 75% which was not significant statistically. Conclusion : Surgery plays an important role in the management of patients with multidrug-resistant Mycobacterium tuberculosis infection. Aggressive pulmonary resection should be performed for resistant Mycobacterium tuberculosis infection to avoid treatment failure or relapse. Especially all cavitary lesions on preoperative chest roentgenogram should be resected completely. If all of them could not be resected perfectly, you should not open the thorax.
