In recent years, in spite of medical advancement, tuberculosis (TB) remains a worldwide health problem. Although many laboratory methods have been developed to expedite the diagnosis of TB, delays in diagnosis remain a major problem in the clinical practice. Because of the slow growth rate of the causative agent Mycobacterium tuberculosis, isolation, identification, and drug susceptibility testing of this organism and other clinically important mycobacteria can take several weeks or longer. During the past several years, many methods have been developed for direct detection, species identification, and drug susceptibility testing of TB. A good understanding of the effectiveness and practical limitations of these methods is important to improve diagnosis. This review summarizes the currently-used advances in nonmolecular and molecular diagnostics.

2.Primary hepatic tuberculosis mimicking intrahepatic cholangiocarcinoma: report of two cases.
Annals of Surgical Treatment and Research 2015;89(2):98-101
Hepatic tuberculosis (TB) is usually associated with pulmonary or miliary TB, but primary hepatic TB is very uncommon even in countries with high prevalence of TB. The clinical manifestation of primary hepatic TB is atypical and imaging modalities are unhelpful for differential diagnosis of the liver mass. Image-guided needle biopsy is the best diagnostic method for primary hepatic TB. In the cases presented here, we did not perform liver biopsy because we believed the liver masses were cholangiocarcinoma, but primary hepatic TB was ultimately confirmed by postoperative pathology. Here we report two cases of patients who were diagnosed with primary hepatic TB mimicking mass-forming intrahepatic cholangiocarcinoma.

3.Diagnosis of Pulmonary Tuberculosis: Recent Advances and Diagnostic Algorithms.
Tuberculosis and Respiratory Diseases 2015;78(2):64-71
Pulmonary tuberculosis (TB) persists as a great public health problem in Korea. Increases in the overall age of the population and the rise of drug-resistant TB have reinforced the need for rapid diagnostic improvements and new modalities to detect TB and drug-resistant TB, as well as to improve TB control. Standard guidelines and recent advances for diagnosing pulmonary TB are summarized in this article. An early and accurate diagnosis of pulmonary TB should be established using chest X-ray, sputum microscopy, culture in both liquid and solid media, and nucleic acid amplification. Chest computed tomography, histopathological examination of biopsy samples, and new molecular diagnostic tests can be used for earlier and improved diagnoses, especially in patients with smear-negative pulmonary TB or clinically-diagnosed TB and drug-resistant TB.

Tuberculosis continues to be the biggest public health problem worldwide. Tuberculosis verrucosa cutis (TVC) is a verrucose form of cutaneous tuberculosis that occurs in previously sensitised individuals due to exogenous reinfection with Mycobacterium tuberculosis or Mycobacterium bovis, and it reflects good cell-mediated immunity. An elderly man presented with multiple fungating growths, which were painless but associated with mild itching and serous discharge, on the right foot for 40 years. The lesions were free from deeper structures and no inguinal lymphadenopathy was observed. A provisional diagnosis of epithelioma was made based on the features described. However, incisional biopsy indicated that the lesions were tuberculous. As part of the anti-tubercular therapy, the lesions were excised and the wounds covered with split-thickness skin graft. The patient's recovery was uneventful, with no graft loss or infection reported. This case illustrates the importance of recognising cutaneous forms of tuberculosis, especially TVC, as an important differential diagnosis of epithelioma.

Tuberculosis of the thyroid gland is an uncommon disease and primary involvement of thyroid is even more rare. It is a rare disease even in countries in which tuberculosis is endemic. The diagnosis is often difficult as the clinical presentation has no distinct characteristics. Clinical course of the disease may resemble toxic goiter or acute thyroiditis or may follow a subacute or chronic growth pattern without specific symptomatology. Histologically presence of necrotizing epithelioid cell granulomas along with langhans type giant cells are the hallmark of thyroid tuberculosis. Demonstration of acid fast bacilli by ZN staining confirms the diagnosis, but this stain is frequently negative in tissue sections.

Spondylolisthesis coexisting with tuberculosis is rarely reported. There is a controversy whether spondylolisthesis coexists or precedes tuberculosis. Few cases of pathological spondylolisthesis secondary to tuberculous spondylodiscitis have been reported in the lumbar and lumbosacral spine. All cases in the literature presented as anterolisthesis, except one which presented as posterolisthesis of lumbar spine. Spondylolisthesis in the cervical spine is mainly degenerative and traumatic. Spondylolisthesis due to tuberculosis is not reported in the lower cervical spine. The exact mechanism of such an occurrence of spondylolisthesis with tuberculosis is sparsely reported in the literature and inadequately understood. We report a rare case of high grade pathological posterolisthesis of the lower cervical spine due to tubercular spondylodiscitis in a 67-year-old woman managed surgically with a three-year follow-up period. This case highlights the varied and complex presentation of tuberculosis of the lower cervical spine and gives insight into its pathogenesis, diagnosis, and management.

7.Congenital Tuberculosis: Report of an Autopsy Case.
Journal of Korean Medical Science 1990;5(1):59-64
An autopsy case of congenital tuberculosis is described in a 41-day-old female infant who was born to a mother having active pulmonary tuberculosis. The primary complex was seen in the liver and portal lymph nodes, and there was a generalized miliary dissemination including lung, liver, spleen, pancreas, adrenals, thyroid, thymus, kidneys, brain, and bowel. The organism was confirmed to be Mycobacterium tuberculosis. The tubercles were histopathologically of various chronicity and characterized by massive caseation and fairly poor peripheral lymphohistiocytic reaction. Giant cell response was also minimal. It should be stressed that although rare, tuberculosis is still an important disease in Korea that can involve fetus or newborn infants if pregnant women are untreated or unnoticed for her tuberculosis.

BACKGROUND: Early detection of tuberculosis (TB) is challenging in resource-poor settings because of limited accessibility to molecular diagnostics. The aim of this study was to evaluate the performance of the loop-mediated isothermal amplification kit (TB-LAMP) for TB diagnosis compared with conventional and molecular tests. METHODS: A total of 290 consecutive sputum samples were collected from May till September, 2015. All samples were processed using the N-Acetyl-L-cysteine (NALC) NaOH method and tested by smear microscopy, solid and liquid culture, real-time PCR, and TB-LAMP. RESULTS: The sensitivity of TB-LAMP for smear-positive and smear-negative samples with culture positivity was 92.0% and 58.8%, respectively. TB-LAMP was positive in 14.9% of TB culture-negative samples; however, all those samples were also positive by real-time PCR. In addition, none of the samples positive for nontuberculous mycobacteria by culture were positive by TB-LAMP. The overall agreement between TB-LAMP and real-time PCR was good; however, the concordance rate was significantly lower for real-time PCR positive samples with Ct values of 30–35. CONCLUSIONS: TB-LAMP could replace smear microscopy and increase TB diagnostic capacity when Xpert MTB/RIF is not feasible because of poor infrastructure.

9.Analysis of clinical manifestations and diagnosis of 102 children with bronchial tuberculosis.
Chinese Journal of Pediatrics 2012;50(10):737-739
OBJECTIVEMost of Endobronchial tuberculosis (EBTB) of children is caused by the bronchial erosion from the scrofula close to the bronchus. Due to its complicated mechanism, pediatricians have limited knowledge on the endobronchial tuberculosis, which makes the misdiagnosis rate high. This work explored the clinical features and diagnostic methods of endobronchial tuberculosis (EBTB), to improve the understanding of this disease.
METHODA total of 102 cases with endobronchial tuberculosis (EBTB) were investigated by analyzing clinical and bronchoscopic features, imaging manifestation, PPD results and etiological examination; 71 cases were male, 33 were female, the youngest was 4 months old, and the oldest was 10 years old. The patients were treated in the fourth ward of the Department of Internal Medicine, Beijing Children's Hospital, Capital Medical University.
RESULTOf the 102 cases, 71 (69.6 percent) were infants and young children. (1) Age and clinical presentation: Infants and young children were more common, the main clinical manifestations were fever and cough, physical examination may find decreased breath sounds, wet and dry rale and wheezing. (2) In 81 cases who received CT there was bronchial obstruction, in 43 cases there were simultaneous manifestations of primary pulmonary tuberculosis (mediastinal and hilar lymph node enlargement and/or pulmonary consolidation), 21 cases had only manifestations of primary tuberculo. (3) The results of PPD: the positive rate was 95%. (4) Bronchoscopic feature: presence of mucosal swelling, caseous necrosis, bronchial stenosis/extrabronchial compression, granulomatous lesions and lymph node bronchial fistula. (5) Bacteriologic results: 21 patients were bacteriologically positive.
CONCLUSIONBronchial tuberculosis was more common in infants and young children, their major clinical manifestations were fever, cough, common findings on lung imaging was mediastinal and hilar lymph node enlargement and/or pulmonary consolidation, bronchial obstruction should be considered manifestations of bronchial tuberculosis, positive PPD should support the clinical diagnosis. Diagnosis can be confirmed by positive bacteriological tests.

10.A Case Report of 3 Clinical Types of Cutaneous Tuberculosis Simultaneously Appeared on One Person.
Korean Journal of Dermatology 1977;15(2):249-253
Tuberculosis of the skin may present clinically as plaques, ulcers, verrucous, lesions, nodules, tumors, vegetatives reactions, and cicartricial infiltration. The reaction of the host to the presence of Mycobacterium tuberculosis also varies with the extent and the degree of invasion, the virulence of the bacilli, and nonspecific factors such as age and generaI state of health. The incidence of cutaneous tuberculosis has tendency to decline in the world because of thc availability of effective antiTB drugs, elimination of infected milk herbs, and an elevation of living standards, but in Korea, cutaneous tuberculosis remained to be a significant medical problem. We experienced 21 year-old male who had a case of 3 clinical types including Lupus vulgaris, Scrofuloderma, Papulonecrotic tuberculid. Diagnosis of 3 clinical types vere established by clinical history and signs, histo pathology, tuberculin test and effective of treatment vith INH, streptomycin and literature were reviewed.
