Intravesical instillation of the bacillus Calmentte-Gu$\acute{e}$rin(BCG), an attenuated strain of Mycobacterium bovis, is an approved method for the treatment of superficial bladder cancer. Because BCG is a living organism, the potential for infection exists. BCG is generally well tolerated, with complications in less than 5% of those treated with use of current practices. The most frequent symptoms of toxicity associated with intravesical BCG immunotherapy include bladder irritation, frequency, and dysuria. Systemic reactions are less common but more serious than local side effects, and include fever, chills, malaise, rash, hepatitis, pneumonitis, arthritis and sepsis. In rare cases, BCG treatment can result in a systemic infection that requires antituberculous therapy. The pulmonary toxicity that results from intravesical BCG treatment is generally characterized by one of two types : systemic allergic reaction with pulmonary reticulonodular opacities depicted on chest radiographs with cellular findings consisting of activated lymphocytes, and actual BCG mycobacteremia with a miliary pattern depicted on chest radiographs and granuloma formation which rarely results in positive acid-fast stain or culture results. Recently we experienced two types of pulmonary complications following intravesical BCG immunotherapy in patients with superficial bladder cancer. We report two cases with a review of literatures.

Background: Diffuse panbronchiolitis (DPB) is a chronic obstructive pulmonary disease distinguished from bronchial asthma, chronic bronchitis, pulmonary emphysema, bronchiectasis, or alveolitis. It is prevalent in Japan, but is known to be rare outside of Japan. Only a few cases in Chinese, Italian, Noirth American and Korean have been reported. During recent two years we have found 16 cases of DPB in Seoul National University Hospital and analyzed the clinical characteristics. Method: We reviewed the patients' age, sex, duration of illness, smoking history, occupational history and past medical history. And we analyzed patients' symptoms, physical signs, laboratory findings and responses to treatment. Results: 1) Male: female ratio was 2.2:1, the ages ranged from 27 to 72 years old, and the duration of disease varied from 1 to 20 years. 2) Most of the patients were being treated as bronchiectasis, miliary tuberculosis, chronic bronchitis or bronchial asthma before they were diagnosed as DPB. 3) Only one patient was a smoker, and 25% of patients had the occupational history of exposure to particles or gas. And all patients had paranasal sinusitis. 4) High resolution computed tomography (HRCT) was very useful in diagnosing the disease in most of the patients. 5) PFT showed obstructive and restrictive abnormalities, and blood gas revealed hypoxemia in most of the patients. 6) Pseudomonas aeruginosa was isolated in the sputum of four patients (25%). 7) The titers of cold hemaglutinin, RA factor and CRP were elevated in most of the patients. 8) Most of the patients improved after treatment with erythromycin. Conclusion: DPB might not be a rare disease in Korea. So DPB should be suspected in a patient who has chronic cough, sputum, dyspnea and diffuse fine nodular chest X-ray abnormality. HRCT and open lung biopsy should be considered in a patient suspected of DPB.

Background: Analysis of cells in bronchoalveolar lavage(BAL) fluid had been used to predict the histologic changes of the bronchioles and alveoli in patients with interstitial lung diseases(ILD). Definitive diagnosis can be a1so made in some cases of ILD, such as histiocytosis. However, there are a few data of the cellular components in BAL fluid in normal Korean individuals and in patients with ILD. In order to evaluate the role of the cellular analysis of BAL fluid in prediction of alveolitis and differential diagnosis among ILDs, we compared the cellular components in BAL fluid from 50 normal individuals and 86 ILD patients. Method: BAL was performed by instillation and retrievement of normal saline with fiberoptic bronchoscopy. The cell number was counted by Hemocytometer. Differential count was done up to 500 cells on slides prepared by Diff-Quik stain and non-specific esterase stain. We compared the recovery rate(RR), cell numbers(CN), and percentages of each cellular components(CP). Results: The results were as follows: 1) There was no difference in RR, CN and CP between the normal smoker group and normal non-smoker group. 2) Total cell numbers recoverd in BAL fluid increased in collagen vascular diseases(CVD), hypersensitivity pneumonitis(HP), idiopathic pulmonary fibrosis(IPF), and miliary tuberculosis(Mil TBC) groups. 3) The percentage of lymphocytes increased in HP, IPF and Mil TBC groups. Macrophage percentages increased in HP, IPF, and Mil TBC groups. Neutrophil percentages were increased in CVD, HP, IPF and Mil TBC groups. Eosinophil percentages were increased in HP, IPF and Mil TBC groups. The numbers of each cells showed same findings as the percentages did. Conclusion: The analysis of cellular components of BAL fluid can predict the presence of alveolitis in many cases of ILDs. However, It was not helpful in differential diagnosis among ILDs.

Purpose : The incidence of tuberculous meningitis in Korean children has been markedly decreased after 1980s, but this disease has still occurred with low rate. Therefore, it may be suspected that delayed diagnosis and treatment will be happened because of lacking of clinical experiences and indistinguishable other meningitis, so it is important to make early diagnosis and treatment of tuberculous meningitis concerning with the prognosis. In this aspect, we conducted study to concern and investigate sustainly about the diagnostic criteria, clinical characteristics, radiological findings, complications, and prognosis of typical or atypical tuberculous meningitis in children. Methods : Forty four children who were hospitalized and treated due to tuberculous meningitis in pediatric wards of Our Lady of Mercy Hospital, St. Holy Hospital, St. Vincent Hospital and Uijungbu St. Mary Hospital from January 1985 to June 1996 were included in this study. We reviewed medical records of these patients retrospectively. Results : 1) The tuberculous meningitis has occured continuosly since mid-1980s. The highest 2) The diagnosis was made by contact history of active tuberculous patients, positive tuberculin test, responses of antituberculous antibiotics and discovery of Mycobacterium tuberculosis from CSF or other specimens. Among patients, 7 children(16%) were not vaccinated with BCG, and only 18 children(40%) were positive in tuberculin test. 3) The symptoms and signs of our patients on initial examinations were fever, vomiting, headache, lethargy, poor feeding, weight loss, neck stiffness, convulsion, abdominal pain and motor deficits. 4) The findings of initial CSF samples revealed leukocyte $239.5/mm^3$(mean) with lymphocyte predominant, elevated protein levels(mean;259.5mg%) and low sugar level(mean;40.7mg%). And the ratio of CSF/blood sugar was 0.407. But, atypical CSF findings were seen in 31.8% patients. 5) On brain imaging study, 34 out of 39 children had findings of hydrocephalus, basilar meningeal enhancement, infarction and subarachnoidal inflammations etc. On chest X-ray, the findings of miliary tuberculosis(34.1%), normal finding(29.5%), parenchymal infiltrations (11.4%) and calcifications(9.1%) were showed. 6) In neurological clinical stage, there were twenty-six children(59%) in stage 1, fourteen children(32%) in stage 2 and four children(9%) in stage 3. The late sequeles were encountered by 29.5% with mild and 4.6% with severe neurological injury. The most common neurological injury was quadriplegia and the mortality rate was 6.8%. 7) The SIADH was developed in 20 children(45.5%) after the 4th hospital day. Half of all SIADH patients were symptomatic. Conclusion : Tuberculosis meningitis is still an important extrapulmonary disease with high morbidity and mortality. Early diagnosis with clinical contact history of active tuberculosis and radiological imaging examinations and early treatments are essential in order to prevent and decrase the rate of late sequeles and death.
