Background : Pulmonary tuberculosis with a remaining cavitary lesion is considered to be a problem with the course of treatment. In particular, re-treatment cases tend to respond poorly to current anti-tuberculosis agents. Therefore the factors that are related with the poor closure of a cavitary lesion in pulmonary tuberculosis during treatment were evaluated. Methods : A retrospective review of the medical records and chest X -ray films of 68 patients who had chemotherapy for the pulmonary tuberculosis with cavitary lesions was made. All the patients had been followed up for more than 12 months at National Masan Tuberculosis Hospital as of Aug. 2000. Results : The male to female ratio was 3.9:1.72.4% of the patients were between 20 to 50 years of age. 66.2% of the cavitary lesions on the chest X-ray films were confined to the upper lung fields : 36.8% in the right upper lung field and 29.4% in the left upper lung field. 82.4% of the cavities were less than 40 mm in their size, and 83.8% were less than 6 mm thick. The cavitary lesions were closed in 48 cases and remained in 20 cases during a follow-up period of more than 12 months. The factors that are thought to affect to the outcomes of the cavities were age, past medication history, the number of unused drugs, and the number of sensitive drugs. Conclusion : In the treatment courses of pulmonary tuberculosis with cavitary lesions, the following factors are associated with less desirable outcome:an age over 45, a past medication history of more than 2 courses of treatment, The number of unused drugs not exceeding average 6 and the number of sensitive drugs not exceeding average 7.
A case of pulmonary aspergillosis, strongly suspected before operation and confirmed after surgical intervention, was reviewed with related literatures. It has become to be a well recognized fact that pulmonary mycosis generally results from sapro-phytic colonization of previous lung cavities usually due to pulmonary tbc, lung abscess, cyst of bronchiectasis. Recently, the author experienced one case of pulmonary aspergillosis which had been diagnosed and treated as tuberculosis for 6 years. Sputum culture, immunologic study and X-ray findings constitute essential part of diagnosis. Surgical resection is the treatment of choice combined with systemic administration of anti-fungal agents to eradicate the disease completely.

According to the nationwide survey of tuberculosis from 1965 to 1995, the incidence and drug resistance rate of tuberculosis have been decreased in Korea, but the prevalence of multidrug resistance of Mycobacterium tuberculosis is still a serious problem. The purpose of this study is to investigate the drug resistance rate and pattern of tuberculosis in Daejeon from 2001 to 2008. Of the total 581cases where the drug susceptibility test was performed, resistance to at least one anti-TB drug was found in 104 cases(17.9%) of these, 68(11.7%) were resistant to at least INH and 41(7.1%) were resistant to at least RFP. Single-drug resistance was found for isolates from 37(6.4%) ; 18(3.1%) of these were resistant to INH and 5(0.9%) to RFP. Multidrug resistance, where TB was resistant to at least isoniazid and refampin, was found in 35 cases(6.0%). and Factors associated with MDR-TB included age under 40-60.The drug-resistance rate of pulmonary TB, especially MDR-TB, is higher in the initial treated patients at a private referral hospital than in those in the pubulic sector. Initial drug resistance is common and the drug susceptibility test is informative for pulmonary TB patients who have not received previous TB treatment. The need for an improved control program, coupled with early diagnosis of MDR-TB, to reduce the spread and development of resistance. Multidrug resistance rate is still problem in korea. Efforts to decrease multidrug resistance rate either independently or in cooperation with the pubulic sector will be needed.
Background : The prevalence of multidrug resistant tuberculosis (MDR-TB), resistant to isoniazid (INH) and rifampin (RFP), was 5.3% worldwide in 1995 and its increment has raised important public health problems. Resistance to RFP, one of the key drugs in the treatment of tuberculosis, results in grim clinical outcome. Recently rapid detection of RFP-resistant mutations in rpoB gene based on PCR method has become available. This study evaluated the prevalence of RFP resistance in first diagnosed, treatment failure, and recurred patients using INNO-LiPA test, and compared the results of INNO-LiPA with those of conventional mycobacterial drug susceptibility test. Methods : Forty-six patients, who were diagnosed of pulmonary tuberculosis and had revealed positive sputum AFB smear, were enrolled in this study from 1998 to 2002. The cases were classified as one three groups; first diagnosed, treatment failure, or recurred. RFP resistance was studied using an INNO-LiPA Rif. TB kit and compared with that obtained from drug susceptibility based on M. tuberculosis culture study. Results : Twenty-one out of 46 patients were enrolled under first diagnosis of pulmonary tuberculosis, 17 under treatment failure with first line drugs, and 8 under recurrence. The positive and negative predictive values of INNO-LiPA test in diagnosis in RFP resistant tuberculosis compared with conventional mycobacterial drug susceptibility test were 85.7% and 76.0%, respectively. INNO-LiPA result revealed rpoB gene mutation in 20 (80.0%) out of 25 patients who were diagnosed as treatment failure or recurrence, but in only 4 (19.0%) out of 21 patients who were first diagnosed as pulmonary tuberculosis. Conclusion : This study showed that RFP resistance could be diagnosed rapidly and accurately using INNO-LiPA test and that this test might be helpful for choosing second line anti-mycobacterial drugs. It might be of great help in clinical diagnosis and decision when used in complimentarily with drug susceptibility test based on M. tuberculosis culture.

Background : Pulmonary tuberculosis is one of the diseases characterized granuloma formation which was controlled by cellular immune reactions. In the process of granulomatous changes, activated alveolar macrophages and T lymphocytes secrete many cytokines including interleukin-1 (IL-1), tumor necrosis factor-alpha(TNF-$\alpha$), interferon-gamma(IFN-$\gamma$) which mediate inflammatory reactions. Intercelluar adhesion molecule-1(ICAM-1) also known to major role player in inflammatory processes, and increased cellular expressions when endothelial cell was stimulated by IL-1, TNF and IFN. Method : To evaluate relationships among cellular immune reactions and clinical stages, pulmonary tuberculosis patients were classified into three groups according to their clinical stages including minimal, moderate and far advanced tuberculosis. TNF-$\alpha$ IFN-$\gamma$, sICAM-1 (soluble form of ICAM-1) were measured at the time of diagnosis and after 6-months anti-tuberculosis medications by radioimmuno assay or enzyme linked immunosolvent assay. Result : TNF-$\alpha$, IFN-$\gamma$, sICAM-1 were significantly increased in moderate and far advanced pulmonary tuberculosis patients but no meaningful changes in minimal staged patients. 6-months anti-tuberculosis medications reduced serum sICAM-1 levels significantly, related to clinical improvement but no significant changes were found in the serum levels of TNF-$\alpha$ and IFN-$\gamma$. In the point of correlations. positive ones revealed between TNF-$\alpha$ and sICAM-1, also between IFN-$\gamma$ and sICAM-1 but no correlation between TNF-$\alpha$ and IFN-$\gamma$. Conclusion : Measurement of serum sICAM-1 could be useful parameter to evaluate the severity of pulmonary tuberculosis and to monitor disease activities during anti-tuberculosis medications.
Background: Missing isoniazid (INH) resistance during tuberculosis (TB) diagnosis can worsen the outcomes of INH-resistant TB. The BD MAX MDR-TB assay (BD MAX) facilitates the rapid detection of TB and INH and rifampin (RIF) resistance; however, data related to its performance in clinical setting remain limited. Moreover, its effect on treatment outcomes has not yet been studied. Methods: We compared the performance of BD MAX for the detection of INH/RIF resistances to that of the line probe assay (LPA) in patients with pulmonary TB (PTB), using the results of a phenotypic drug sensitivity test as a reference standard. The treatment outcomes of patients who used BD MAX were compared with those of patients who did not. Results: Of the 83 patients included in the study, the BD MAX was used for an initial PTB diagnosis in 39 patients. The sensitivity of BD MAX for detecting PTB was 79.5%. The sensitivity and specificity of BD MAX for INH resistance were both 100%, whereas these were 50.0% and 95.8%, respectively, for RIF resistance. The sensitivity and specificity of BD MAX were comparable to those of LPA. The BD MAX group had a shorter time interval from specimen request to the initiation of anti-TB drugs (2.0 days vs. 5.5 days, p=0.001). Conclusion: BD MAX showed comparable performance to conventional tests for detecting PTB and INH/RIF resistances. The implementation of BD MAX as a diagnostic tool for PTB resulted in a shorter turnaround time for the initiation of PTB treatment.

Background: Multidrug-resistant tuberculosis (MDR-TB) is an increasing public health problem and poses a serious threat to global TB control. Fluoroquinolone (FQ) and aminoglycoside (AG) are essential anti-TB drugs for MDR-TB treatment. REBA MTB-FQ$^{(R)}$ and REBA MTB-KM$^{(R)}$ (M&D, Wonju, Korea) were evaluated for rapid detection of FQ and kanamycin (KM) resistance in MDR-TB clinical isolates. Methods: M. tuberculosis (n=67) were isolated and cultured from the sputum samples of MDR-TB patients for extracting DNA of the bacilli. Mutations in genes, gyrA and rrs, that have been known to be associated with resistance to FQ and KM were analyzed using both REBA MTB-FQ$^{(R)}$ and REBA MTB-KM$^{(R)}$, respectively. The isolates were also utilized for a conventional phenotypic drug susceptibility test (DST) as the gold standard of FQ and KM resistance. The molecular and phenotypic DST results were compared. Results: Sensitivity and specificity of REBA MTB-FQ$^{(R)}$ were 77 and 100%, respectively. Positive predictive value and negative predictive value of the assay were 100 and 95%, respectively, for FQ resistance. Sensitivity, specificity, positive predictive value and negative predictive value of REBA MTB-KM$^{(R)}$ for detecting KM resistance were 66%, 94%, 70%, and 95%, respectively. Conclusion: REBA MTB-FQ$^{(R)}$ and REBA MTB-KM$^{(R)}$ evaluated in this study showed excellent specificities as 100 and 94%, respectively. However, sensitivities of the assays were low. It is essential to increase sensitivity of the rapid drug resistance assays for appropriate MDR-TB treatment, suggesting further investigation to detect new or other mutation sites of the associated genes in M. tuberculosis is required.

Background: Even today when chemotherapy has been established as a treatment for tuberculosis and the prevalence of tuberculosis is gradually decreasing, multi-drug resistance tuberculosis still results in poor treatment performance and lowered survival periods. This research sought to analyze the surgery of multi-drug resistance tuberculosis, and determine the usefulness and danger of surgery in connection with this disease. Material and Method: Starting from February 1990 to February 2002, retrospective surveys were conducted targeted at 21 cases involving 20 patients who underwent surgery due to multi-drug resistance tuberculosis. The survey included 14 males cases and 6 females cases with the age averaging 42.8$\pm$12.1 years. 10.3$\pm$7.6 years on average passed after patients were initially diagnosed with tuberculosis. 13 patients (65%) tested positive in the pre-operative sputum AFB test, and all showed resistance against an average of 3.5 anti-tuberculosis agents including INH and RFP. Pre-operative radiologic examinations revealed cavitary lesions in 15 patients (75%), and three patients had lesions in the both lung fields, with the major lesions existing in the unilateral area. 13 patients (75%) failed negative conversion with medical treatment, while two patients (10%) with recurrent hemoptysis and five patients (25%) with lesions involving high recurrence-rate received the operation. Operations included nine cases (40%) of pneumonectomy, nine cases (45%) of lobectomy, and three cases of lobectomy with segmentectomy. The average follow-up period of patients stood at 23 months. Result: There was no post-operative death, and found were a total of eleven cases involving complications were found: three cases of long-term air leakage, three cases of bleeding requiring re-operation, two cases of empyemas due to broncho-pleural fistula, and one case of atelectasis, wound infection and chest wall fistula each. Eleven cases (85%) of negative conversion were completed immediately after the operation, and two cases failed negative conversion. Eleven months after the operation, the disease recurred in one case of negative conversion patients, and the patient was cured by completion pneumonectomy. Conclusion: If patients' lung function was sufficient and appropriate resection was possible, multi-drug resistance tuberculosis could achieve high-rate negative conversion and cure using combination of surgical and medical treatment, and also there were not many serious complications.
Although the incidence of tuberculosis has been decreased due to new anti-tuberculous agents, improved socioeconomic status and development of multimodal preventive methods, in recent that is increased due to low vaccination rate and appearance of multidrug resistence organism. And the incidence of pyogenic shoulder joint arthritis is increasing due to frequent injection therapy as primary treatment. We have managed the mixed shoulder joint arthritis-pyogenic and tuberculous-with arthroscopic debridement and antituberculous medication successfully and then we report this case with relevant literatures.
Tuberous sclerosis is a syndrome characterized by the facial skin lesion, epilepsy, and mental retardation. Pulmonary involvement is uncommon, but when the lung is involved by tuberous sclerosis it shows characteristic reticulonodular infiltration and cystic changes. We experienced a 34-year-old female patient of known tuberous sclerosis admitted due to pneumothorax. Chest PA showed diffuse fine reticulonodular infiltration and chest CT revealed diffuse cystic changes of the lung. Pleurodesis with tetracycline was done to prevent recurrence, but chylothorax occurred four months after the treatment. Pleurosis was tried again and anti estrogen treatment began.
