The incidence of the tuberculosis infection has decreased worldwide, but it is still easy to find the patients in some areas or some races. And it is very difficult to diagnose and treat the patients who are infected by the atypical tuberculosis. Facial skin infection by atypical tuberculosis has not been reported. We report the case of a 62-year-old woman who developed facial skin and soft tissue necrosis caused by Mycobacterium abscessus after receiving liquid silicone injections and face lift operation. We cultured the pathogenic organism and treated the wound with radical curettage, debridement, skin graft and tuberculosis medication.

목 적 : 투베르쿨린 피부반응 검사는 결핵균 감염을 조사하는 방법으로, 전 세계적으로 널리 사용되고 있다. 그러나 여러 가지 요소에 의해 검사 결과의 판독에 어려움이 따른다. 2000년 미국흉부학회에서는 피검사자의 위험요소를 고려하여 피부반응 검사의 결과를 판단하도록 권장하였다. 우리나라의 경우 높은 결핵 감염율과 BCG 백신 접종률로 인해 피부반응 검사를 통해 현감염, 과거감염, 그리고 비감염을 구별하기 어렵다. 본 연구는 항결핵 약제의 투여를 결정하는데 피부반응 검사가 얼마나 도움이 되는지 알아보기 위해, 피부반응 검사의 음성 예측도를 조사하였다. 방 법 : 2001년 3월 1일부터 7월 31일까지 한림대학교 부속 춘천성심병원의 호흡기 내과에 입원한 환자를 대상으로, 현재 국내에서 사용되고 있는 Tuber culin PPD RT23 2 TU (0.1 ml)를 Mantoux 검사에 따라 시행하였다. 결핵의 진단기준은 1) 세균학적 진단기준으로 객담에서 결핵균이 배양되거나 현미경 검사로 항산균을 증명한 경우 2) 임상적 진단기준으로는 상기 세균학적 검사에서 결핵균을 증명하지 못하였으나, 방사선학적 또는 조직학적으로 결핵에 합당한 소견이나 증상이 있어서 진료의사가 결핵치료를 시행하기로 결정한 경우로 하였다. 결 과 : 등록된 환자 230명중에서 재입원 및 다른 과에 입원 중 전과되거나 중환자실에 입원한 환자 20명 (8.7%)을 제외한 총 210명의 환자를 대상으로 평가하였다. 환자의 평균연령은 $60{\pm}16.8$세였고, 남녀비는 1.28 : 1 (남118명, 여 92병)이였다. 결핵으로 진단된 환자는 53명 (25.2%)이였다. 폐결행이 45명(84.9%)이었고, 세균학적 검사에서 항산균 도말 양성이 22명(배양 양성 13, 배양 음성 9) 이었고, 임상적 진단기준으로 판단한 경우가 23명이었다. 결핵성 늑막염이 8명(15.1%)이었고, 조직학적으포 진단 된 경우가 4명, 임상적으로 판단되어 치료한 경우가 4명이었다. 미국흉부학회의 피부반응 검사의 판단기준에 따라 각각의 환자를 음성 및 양성으로 판정하였을 때, 음성 예측도는 92.3%, 양성 예측도는 47.3%, 민감도와 특이도는 각각 83%, 68.8%이었다. 결 론 : 입원한 호흡기 내과 환자를 대상으로 시행한 투베르쿨린 피부반응 검사는 92.3%의 높은 음성 예측도를 보였으며, 피부반응 검사가 음성으로 판단된 환자에서 항결핵 약제의 투여 여부를 결정하는데 중요한 단서를 제공할 것으로 생각된다.

Background: There are several active tuberculosis (TB) cases in Korean high schools each school year. The risk of transmission in schools is extremely high due to the considerable time spent in closed classrooms. We evaluated the control of latent tuberculosis infection in Korean high schools. Methods: When a student was identified with active TB, tuberculin skin testing was performed on their classmates and on students in their same school grade. When a student had a positive tuberculin skin tests (TST), they underwent follow-up testing with QuantiFERON-TB Gold In-Tube (QFT). The manufacturer recommended a cut-off of 0.35 IU/mL to determine QFT positivity was applied. Results: A total of 131 pulmonary tuberculosis (TB) patients were included based on the criteria for screening TB contacts in the National Tuberculosis Control Program. Seventy-five (57.2%) students tested smear positive. TST were performed on 7,109 students who were classmates of, or in the same grade as, a TB patient. Of the contacts, 1,231 students (17.3%) were TST positive and they were screened with QFT. Six hundred-sixty-six (55.0%) of the tested students returned a positive QFT result and the rate of positivity was significantly associated with the increasing size of TST indurations (p<0.0001). Conclusion: The use of QFT resulted in approximately 45% of TST positive students not being given chemoprophylaxis.

Background: Skin biopsy is the method to assist clinicians to make definite dermatological diagnosis which further helps in holistic management. Skin cancers are relatively rare clinical diagnosis in developing countries like Nepal, but the prevalence is on rise. Objectives: To investigate the profile of skin biopsies and frequencies and pattern of skin cancers in a tertiary care centre of Western Nepal. Materials and Methods: The materials consisted of 434 biopsies (1.37%) out of 31,450 OPD visits performed in the Department of Dermatology, Manipal Teaching Hospital, Pokhara, Nepal, during the period of Dec 2011-Nov 2014. Data were collected and analyzed using SPSS-16 with reference to incidence, age, sex, race and clinical and histopathological features. Results: The commonest disorders observed in biopsies were papulosquamous lesions, skin tuberculosis of different types, benign skin tumors, leprosy, collagen and fungal diseases. Viral diseases were rarely seen, probably due to straight forward clinical diagnosis. Dermatological malignancies accounted for 55/434 (12.67%) of biopsies. Skin disorders in general were commoner in females 280/434 (64%), including malignancies 32/55(58.2%). Mean age of patients with skin cancer was 54.5 years. Facilities for proper laboratory investigation of dermatological disorders will improve the quality of life. Conclusions: The most prevalent lesion in skin biopsies was papulosquamous disorders followed by skin tuberculosis of different types. Dermatological malignancy constituted 55/434 (12.67%) cases. The prevalence of skin malignancy is on rise in Nepalese society probably due to increase in life expectancy and better diagnostic services.

Patients with immune-mediated inflammatory diseases (IMIDs) are increasingly being treated with anti-tumor necrosis factor (TNF) agents and are at increased risk of developing tuberculosis (TB). Therefore, diagnosis and treatment of latent TB infection (LTBI) is recommended in these patients due to the initiation of anti-TNF therapy. Traditionally, LTBI has been diagnosed on the basis of clinical factors and a tuberculin skin test. Recently, interferon-gamma releasing assays (IGRAs) that can detect TB infection have become available. Considering the high-risk of developing TB in patients on anti-TNF therapy, the use of both a tuberculin skin test and an IGRA should be considered to detect and treat LTBI in patients with IMIDs. The traditional LTBI treatment regimen consisted of isoniazid monotherapy for 9 months. However, shorter regimens such as 4 months of rifampicin or 3 months of isoniazid/rifampicin are increasingly being used to improve treatment completion rates. In this review, the screening methods for diagnosing latent and active TB before anti-TNF therapy in patients with IMIDs will be briefly described, as well as the current LTBI treatment regimens, the recommendations for managing TB that develops during anti-TNF therapy, the necessity of regular monitoring to detect new TB infection, and the re-initiation of anti-TNF therapy in patients who develop TB.

The drug reaction with eosinophilia and systemic symptom (DRESS) syndrome is a severe adverse drug-induced reaction which includes a severe skin eruption, fever, hematologic abnormalities (eosinophilia or atypical lymphocytes) and internal organ involvement. The most frequently reported drug was anticonvulsants. The diagnosis of DRESS syndrome is challenging because the pattern of cutaneous eruption and the types of organs involved are various. The treatments for DRESS syndrome are culprit drug withdrawal and corticosteroids. Here we report a 71-year-old man with skin eruption with eosinophilia and hepatic and renal involvement that appeared 4 weeks after he had taken anti-tuberculosis drugs (isoniazid, ethambutol, rifampicin, and pyrazinamide), and resolved after stopping anti-tuberculosis drugs and the administration of systemic corticosteroids. DRESS recurred after re-challenging isoniazid, we identified isoniazid was causative drug.

Restoration of skin reactivity to 1 TU of tuberculin (RT23) by repeated tests at 10 days interval has been investigated in the BCG vaccinated or unvaccinated primary school children. The results obtained are as follows. 1) Tuberculin reactors showing 6 mm or larger induration to the first tests were 20.0% in the first grade school children and 33.3% in the sixth grade children. Six millimeter or larger reaction than that of the first reaction was found in 14.9% of the first grade children and in 34.6% of the sixth grade children. 2) Six millimeter or larger reactors were 10.8% of the first grade children without BCG scar against both first and second tests and 11.8% of the sixth grade children on first tests and 10.6% on second tests. There was none or very few, if any, in number of 6 mm or larger difference between the first and second tests among children without BCG scar. In addition, there was no children shown 6 mm or larger second reaction than that of the first reaction and thus those reactors seemed to be natural infection. 3) From questionaire survey, parents of 73.3% of the first grade children and of 72.7% of the sixth grade children were aware of BCG vaccination of their children, while parents of 15.1% and 24.6% of the first and sixth grade children did not know their children's vaccination history even if children possessed BCG scar. 4) Of the first grade children whose parents remembered their BCG vaccination, 65.6% were vaccinated within 4 weeks after birth and 25.5% between 4 weeks and one year. Six millimeter or larger reaction on the first tests was observed in 20.2% of the former group and 15.9% of the latter group, however reactors on the second tests were 32.1% and 31.9% respectively. BCG scar was not observed in 13.9% of children. 5) The majority of children (87.3%) were vaccinated in the skin of deltoid area and some (7.7%) at buttock or other areas. Children received first vaccination at the health centers were 68.5% and 30.3% at hospitals. More than 5 mm reaction was found in 18.7% of the former children and in 15.0% of the latter children. From this study restoration of tuberculin reactivity by repeated tests was found very common among the vaccinated children and thus it should be taken into account for the vaccination policy if it is performed after tuberculin testing.

A recent understanding of the dynamic continuous spectrum of Mycobacterium tuberculosis infection has led to the recognition of incipient tuberculosis, which refers to the latent infection state that has begun to progress to active tuberculosis. The importance of early detection of these individuals with a high-risk of progression to active tuberculosis is emphasized to efficiently implement targeted tuberculosis preventive therapy. However, the tuberculin skin test or interferon-γ release assay, which is currently used for the diagnosis of latent tuberculosis infection, does not aid in the prediction of the risk of progression to active tuberculosis. Thus, a novel test is urgently needed. Recently, simultaneous and systematic analysis of differentially expressed genes using a high-throughput platform has enabled the discovery of key genes that may serve potential biomarkers for the diagnosis or prognosis of diseases. This host transcriptional investigation has been extended to the field of tuberculosis, providing promising results. The present review focuses on recent progress and challenges in the field of blood transcriptional signatures to predict progression to active tuberculosis.
