Background: Limited data on the incidence and clinical characteristics of adult pertussis infections are available in Korea. Methods: Thirty-one hospitals and the Korean Centers for Disease Control and Prevention collaborated to investigate the incidence and clinical characteristics of pertussis infections among adults with a bothersome cough in non-outbreak, ordinary outpatient settings. Nasopharyngeal aspirates or nasopharyngeal swabs were collected for polymerase chain reaction (PCR) and culture tests. Results: The study enrolled 934 patients between September 2009 and April 2011. Five patients were diagnosed as confirmed cases, satisfying both clinical and laboratory criteria (five positive PCR and one concurrent positive culture). Among 607 patients with cough duration of at least 2 weeks, 504 satisfied the clinical criteria of the US Centers for Disease Control and Prevention (i.e., probable case). The clinical pertussis cases (i.e., both probable and confirmed cases) had a wide age distribution ($45.7{\pm}15.5$ years) and cough duration (median, 30 days; interquartile range, 18.0~50.0 days). In addition, sputum, rhinorrhea, and myalgia were less common and dyspnea was more common in the clinical cases, compared to the others (p=0.037, p=0.006, p=0.005, and p=0.030, respectively). Conclusion: The positive rate of pertussis infection may be low in non-outbreak, ordinary clinical settings if a PCR-based method is used. However, further prospective, well-designed, multicenter studies are needed.

Until recently, the tuberculin skin test (TST) has been the only tool available for diagnosing a latent TB infection. However, the development of new diagnostic tools, using the Mycobacterium tuberculosis (MTB)-specific early secreted antigenic target 6 (ESAT-6) and culture filtrate protein 10 (CFP-10) antigens, should improve the control of tuberculosis (TB) by allowing a more accurate identification of a latent TB infection (LTBI). Antigen-specific interferon-gamma ($IFN-{\gamma}$) assays have greater specificity in BCG-vaccinated individuals, and as less biased by nontuberculous mycobacterial infections. Many comparative studies have suggested that those assays have a higher specificity than the TST, and the sensitivity of these assays are expected to remarkably improved if more MTB-specific antigens can become available. Nevertheless, the major obstacle to the widespread use of these tests is the limited financial resources. Similar to other diagnostic tests, the predictive value of $IFN-{\gamma}$ assays depends on the prevalence of a MTB infection in the population being tested. Therefore, prospective studies will be meeded to establish the applicability of these new assays at multiple geographic locations among patients of different ethnicities, and to determine if the $IFN-{\gamma}$ responses can indicate those with a high risk of progressing to active TB.

Dysphagia is common symptom in patients with advanced esophageal cancer, which is not to be resected surgically. Especially when esophagorespiratory fistula is complicated, it leads to rapid deterioration and death due to pulmonary infection. Esophageal intubation relieves dysphagia as simple surgical execution and offers rapid effectiveness. For six patients with inoperable esophageal cancer including three esophago-respiratory fistulas, the palliative esophageal intubation was performed in Korea Cancer Center Hospital, in 1988. Traction technique via high gastrotomy with Celestin tube was used. Adequate palliation of dysphagia was achieved in 5 patients, but wound infection was developed in 2 patients, tube migration in 2 patients, and 2 died in hospital due to sepsis on the 16th and 42nd postoperative day, respectively. In 3 patients with esophagorespiratory fistula complicated after radiation therapy, the intubation was performed urgently and the result was satisfactory in 2 of them that the fistula was occluded successfully and aspiration or pulmonary infection was prevented.

폐경색은 폐동맥의 폐색으로 인해 발생하며 기관지내 세균오염에 의해 폐감염이 흔하게 속발하며 이는 폐농양, 농흉 그리고 기관지 흉막루 등을 일으켜 결국 패혈증에 이르게 할 수 있다. 이러한 이유로 조기 진단이 중요하며 감염 조절을 위해 폐절제 등을 조기에 고려해야 한다. 67세 남자가 호흡곤란을 주소로 응급실에 내원하였다. 흉부 전산화 단층 촬영에서 좌하엽에 침윤성 병변과 소량의 흉수 그리고 늑막 비후가 관찰되었다. 폐색전은 하엽 폐동맥에서 상엽 폐동맥까지 자라나 있었다. 출혈성 경색이 완연한 좌하엽은 절제되었고 좌주폐동맥을 열어 나머지 폐색전을 제거하였다. 수술 후 15개월간 추적 관찰하고 있으며 폐색전이나 폐경색의 재발은 보이지 않았다.

Invasive aspergillosis has emerged as a major cause of life-threatening infections in immunocompromised patients. Recently, patients with chronic obstructive pulmonary disease, who have been receiving corticosteroids for a long period, and immunocompetent patients in the intensive care unit have been identified as nontraditional hosts at risk for invasive aspergillosis. Here, we report a case of invasive pulmonary aspergillosis after influenza in an immunocompetent patient. The patient's symptoms were nonspecific, and the patient was unresponsive to treatments for pulmonary bacterial infection. Bronchoscopy revealed mucosa hyperemia, and wide, raised and cream-colored plaques throughout the trachea and both the main bronchi. Histologic examination revealed aspergillosis. The patient recovered quickly when treated systemically with voriconazole, although the reported mortality rates for aspergillosis are extremely high. This study showed that invasive aspergillosis should be considered in immunocompetent patients who are unresponsive to antibiotic treatments; further, early extensive use of all available diagnostic tools, especially bronchoscopy, is mandatory.

Pulmonary mucormycosis is an uncommon, but important opportunistic fungal infection associated with diabetes mellitus, leukemia, lymphoma and other immunocompromised states. Mucor species grow best in acidic-high glucose medium. which explaining the particular susceptibility of diabetic patient who are ketoacidic. Early consideration of this diagnosis, along with aggressive diagnostic evaluation, is critical to effective therapy and patient survival. We have experienced a case of pulmonary murcomycosis mimicking bilateral pulmonary edema on chest Xray that associated with diabetic ketoacidosis. A brief review of the literature was given.

Infliximab, a TNF-${\alpha}$ antagonist, has been used to treat refractory rheumatoid arthritis, ankylosing spondylitis, Crohn's disease and Behcet's disease. Tuberculosis (TB) is a well-known opportunistic infection in patients receiving infliximab. Therefore, patients should be screened and treated for latent or active TB infection before being administered infliximab. Recently, we encountered a case of military TB during infliximab therapy in a patient suffering from Behcet's disease and uveitis. We report this case with a review of the relevant literature.
