Since the diagnosis of extrapulmonary tuberculosis (EPT) is largely depended on the physician's suspicion in respect of the disease, we believed that it would be worthwhile to scrutinize the clinical characteristics of EPT. Thus, here we present retrospectively evaluated clinical manifestations of patients who were diagnosed as EPT cases in a tertiary referral care hospital. Medical records of 312 patients, diagnosed as having EPT at Yongdong Severance hospital from January 1997 to December 1999, were reviewed retrospectively. In total 312 patients, 149 (47.8%) males and 163 (52.2%) females aged from 13 years to 87 years, were included into this study. The most common site of the involvement was pleura (35.6%). The patients complained of localized symptoms (72.4%) more frequently than systemic symptoms (52.2%). The most common symptom was pain at the infected site (48.1%). Leukocytosis, anemia, and elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were found in 12.8%, 50.3%, 79.3% and 63.1% of the patients, respectively. Twenty-four percent of the patients had underlying medical illnesses such as, diabetes mellitus or liver cirrhosis, or were over 60 years old. In 67.3% of patients, tuberculosis was suspected at the initial visit. However, tuberculosis was microbiologically proven in only 23.7% of the patients. The time interval from the symptom onset to the diagnosis varied, with the mean duration of the period 96 days. Pulmonary parenchymal abnormal lesions were found in 133 patients (42.6%) on chest radiographs. EPT has a wide spectrum of clinical manifestations, so it is difficult to diagnose it. Based on our studies, only 11.2% of the patients were confirmed as EPT. So it is important that the physician who first examines the patient should have a high degree of suspicion based on the chest radiography, localized or systemic symptoms and several laboratory parameters reviewed in this study.

We evaluated the effects of previous pulmonary tuberculosis (TB) on the risk of obstructive lung disease. We analyzed population-based, the Second Korea National Health and Nutrition Examination Survey 2001. Participants underwent chest X-rays (CXR) and spirometry, and qualified radiologists interpreted the presence of TB lesion independently. A total of 3,687 underwent acceptable spirometry and CXR. Two hundreds and ninty four subjects had evidence of previous TB on CXR with no subjects having evidence of active disease. Evidence of previous TB on CXR were independently associated with airflow obstruction (adjusted odds ratios [OR] = 2.56 [95% CI 1.84-3.56]) after adjustment for sex, age and smoking history. Previous TB was still a risk factor (adjusted OR = 3.13 [95% CI 1.86-5.29]) with exclusion of ever smokers or subjects with advanced lesion on CXR. Among never-smokers, the proportion of subjects with previous TB on CXR increased as obstructive lung disease became more severe. Previous TB is an independent risk factor for obstructive lung disease, even if the lesion is minimal and TB can be an important cause of obstructive lung disease in never-smokers. Effort on prevention and control of TB is crucial in reduction of obstructive lung disease, especially in countries with more than intermediate burden of TB.
