Aspergillus Tracheobronchitis and Influenza A Co-infection in a Patient with AIDS and Neutropenia.

Aspergillus tracheobronchitis (AT), an unusual form of invasive pulmonary aspergillosis (IPA), is characterized by pseudomembrane formation, ulcer or obstruction that is predominantly confined to tracheobronchial tree. Hematologic malignancies, neutropenia, solid organ transplantation, chronic corticosteroid therapy and acquired immunodeficiency syndrome (AIDS) are known to be major predisposing conditions. However, since the introduction of highly active antiretroviral therapy, there is only one reported case of AT in AIDS patient.

Primary tumor maximum standardized uptake value measured on 18F-fluorodeoxyglucose positron emission tomography-computed tomography is a prognostic value for survival in bile duct and gallbladder cancer.

Background/aims: Few studies have assessed the prognostic value of the primary tumor maximum standardized uptake value (SUV max) measured by 2-[(18)F]-fluoro-2-deoxy-D-glucose PET-CT for patients with bile duct and gallbladder cancer.

Methods: A retrospective analysis of 61 patients with confirmed bile duct and gallbladder cancer who underwent FDG PET-CT in Kangbuk Samsung Medical Center (Seoul, Korea) from April 2008 to April 2011. Prognostic significance of SUV max and other clinicopathological variables was assessed.

The influence of waist circumference on insulin resistance and nonalcoholic fatty liver disease in apparently healthy Korean adults.

Background/aims: Waist circumference (WC) is a risk factor for metabolic syndrome and is related to insulin resistance (IR) and nonalcoholic fatty liver disease (NAFLD). The purpose of this study was to determine the association between WC and IR and NAFLD in apparently healthy Korean adults.

Methods: The volunteers included in this cross-sectional study comprised 9,159 adults (5,052 men, 4,107 women) who participated in a comprehensive health checkup program.
