  • Pleural effusion is a rare complication in non-tuberculous mycobacterial infection. We report a case of Mycobacterium intracellulare pleuritis with idiopathic pulmonary fibrosis in a 69-year-old man presenting with dyspnea. Pleural effusion revealed lymphocyte dominant exudate. M. intracellulare was identified using a polymerase chain reaction-restriction fragment length polymorphism method and liquid cultures of pleural effusion and pleural biopsy. After combination therapy for M. intracellulare pulmonary disease, the patient was clinically well at a 1-month follow-up.

  • Fungal infections by human pathogenic fungi are increasing globally in elderly, children and immune suppressed or deficient patients. Aspergillus fumigatus is one of the well-known pathogenic fungi and causes aspergilloses in human world widely. However, current identification and classification methods based on its phenotypic characteristics still have limitations. Therefore, currently, molecular biological tools using their DNA sequences are used for genotype identification and classification. In the present study, in order to analyze genetic variations of A. fumigatus clinical isolates, a total of six housekeeping genes were amplified by PCR using specific primer pairs and multi-locus sequence typing (MLST) assay. Results from phylogenetic tree analysis showed that most A. fumigatus strains (88.9%) from respiratory specimens were classified into cluster A and B, and approximately half of A. fumigatus strains (46%) from non-respiratory specimens were classified into cluster C and D. Although the sample size was limited, genetic characteristics of A. fumigatus clinical isolates according to their origins were very similar and well-correlated with other clinical data.

  • Cytomegalovirus (CMV) pneumonia is a serious opportunistic infection in an immunocompromised host such as an AIDS patient or transplant recipient undergoing immunosuppressive therapy. Diffuse alveolar hemorrhage (DAH) is a relatively uncommon condition and it occurs most often in patients with systemic autoimmune disease. However, various types of infectious pneumonia with Mycoplsma hominis, Stenotrophomonas maltophilia and Pneumocystis jirovecii have been reported to be associated with the development of DAH. The association of CMV infection with the development of DAH has rarely been reported. We experienced a case of DAH associated CMV pneumonia and the patient was successfully treated with the use of antiviral agents and steroids.

  • Since Patient Zero of MERS was diagnosed in May 20, 2015, cases of MERS continued to grow. The current situation, which people have been confirmed to be infected, suggested that contaminated indoor air could be the potential cause of hospital-acquired infections. It is important to address the indoor air quality in hospitals because pathogens can spread through air. While the heating, ventilating and air conditioning(HVAC) system is useful managing indoor air quality in hospitals, it can transmit the pathogens if operated improperly. Therefore, it is necessary to remove contaminants in hospitals and operate the HVAC system according to the guidelines, in order to maintain clean indoor air.

  • Cytomegaloviruses (CMVs) are ubiquitous but highly species-specific agents which commonly infect many animals, including humans. Cytomegalovirus (CMV) pneumonia has been one of the most important opportunistic infections in the immunocompromised host for those who have acquired immunodeficiency syndrome (AIDS) or who have received kidney, bone marrow or other organs. Cytomegalovirus infection has been known to be associated with congenital, infantile and adult nephrotic syndrome. We report a rare case of CMV pneumonia with nephrotic syndrome in a 62-year-old female who recovered fully with ganciclovir.

  • Coccidioidomycosis is a common infectious disease in southwestern North America, which is caused by the soil fungus, Coccidioides immitis. Due to the mobility of the modem population, increasing numbers of cases are being diagnosed outside the endemic areas. Moreover, diagnosis in non-endenmic areas may be delayed or confused due to its rarity. Here we report a case of pulmonary coccidioidomycosis in an immigrant. The patient presented with unexplained pulmonary symptoms. A history of recent travel to or immigration from an endemic area may suggest coccidioidomycosis. In addition an early tissue biopsy is helpful in establishing this diagnosis.

  • Lemierre syndrome is characterized by an acute oropharyngeal infection with secondary septic thrombophlebitis of the internal jugular vein and frequent metastatic infections such as septic pulmonary emboli and suppurative arthritis. In the preantibiotic era, this condition generally had a fatal outcome. The presentation is so distinctive that a clinical diagnosis is possible in most cases, and a cure is expected with the appropriate therapy in the majority of patients. We present a case report of Lemierre syndrome with a review of the relevant literature.

  • Diffuse alveolar damage (DAD) is a histological change in lung tissue, and is generally caused by an acute lung injury, which is characterized by bilateral and widespread damages. Localized DAD occurs very rarely. The causes for DAD are numerous, but the chief cause is acute interstitial pneumonia or acute exacerbation of idiopathic interstitial pneumonia, in cases of idiopathic manifestation. The 82-year-old patient, in this case study, showed a DAD lesion in only 1 lobe. The patient was otherwise healthy, with no previous symptoms of DAD. He was admitted to our medical center owing to localized infiltration, observed on his chest radiograph. Laboratory studies showed no signs of infections. DAD was confirmed by a surgical lung biopsy. The patient received corticosteroid treatment and had gradually improved. We report the case of a patient with localized, idiopathic DAD that cannot be classified as acute interstitial pneumonia or acute exacerbation of idiopathic interstitial pneumonia.

  • Sparganosis is a zoonosis caused by the migrating larvae of cestode genus Spirometra. We report a rare form of sparganosis that invades the lung. A 44-year-old man presented with newly appeared pulmonary nodules that were found accidentally on regular medical checkup, and on sequential chest CT, which we checked at an interval of every 2 months, revealed that the pulmonary lesion had migrated. The patient had a medical history of having undergone surgical excisions for sparganosis in muscles and in subcutaneous tissues of the lower abdomen, perianus, thigh, right axilla, and scapula area, several times over 7 years. A right middle lobectomy was performed and the lesion was diagnosed as sparganosis based on the characteristic histological findings.

  • We hereby observe four co-infection cases of pandemic influenza H1N1 and Mycobacterium tuberculosis with various clinical presentations. It may be prudent to consider M. tuberculosis co-infections when patients with pandemic influenza reveal unusual clinical features that do not improve despite appropriate treatments against the influenza, especially in Korea, in the endemic areas of M. tuberculosis.
