Much controversy surrounds the issue of whether HIV infection is a risk factor for developing multidrug-resistant tuberculosis (MDR-TB). In this study, we evaluated the prevalence of and risk factors for MDR-TB in HIV-infected patients at the National Medical Center of Korea. We reviewed the medical records of HIV/TB co-infected patients from January 2005 to May 2011; the drug susceptibility profiles were available for 55 patients. Of these, 32.7% had MDR-TB, which was approximately 3.6 times higher than the prevalence among the general population. Additionally, there were more additional AIDS-defining clinical illnesses in the MDR-TB group than in the non-MDR-TB group (27.8% vs 5.4%, P = 0.032). These results suggest that HIV infection and HIV-related immunosuppresion may contribute to the development of MDR-TB.

Cholelithiasis and choledocholithiasis are uncommon pediatric diseases, although clinicians have seen them with increasing frequency in children in recent years. Moreover, no case of Epstein-Barr virus (EBV) infection with cholelithiasis and choledocholithiasis has been previously reported in the English literature. We report a pediatric patient with EBV infection, a gall bladder stone, and a common bile duct stone, may have had GB and CBD stones prior to her EBV infection, whom we successfully treated with antibiotics and laparoscopic cholecystectomy for cholecystitis.

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.

Bronchial invasion of tuberculous lymphadenitis in children has been reported in areas of high tuberculosis (TB) prevalence as a complication due to primary pulmonary tuberculosis. However, it is rare in immunocompetent adults. When it appears, it often presents as a consequence of the reactivation of TB in the lung parenchyma. Primary TB occurs more frequently in patients with human immunodeficiency virus (HIV), with a history of organ transplants, or undergoing immunosuppressive treatments such as steroids. Furthermore, bronchial invasion of the bronchus by tuberculous lymphadenitis is considered to be very rare even among immunocompromised adults with primary TB, and has never before been reported in Korea. The authors report a case of bronchial invasion of the bronchus by tuberculous lymphadenitis, confirmed by bronchoscopy, in an Acquired Immunodeficiency Syndrome (AIDS) patient.

Streptomycin is currently utilized to treat advanced tuberculosis in Korea. However, the usefulness of intravascular streptomycin is not fully understood. In this study, streptomycin was administered intravenously in 30 patients. Intravenous administration of streptomycin may be a useful route of administration without undesirable toxicities.
