Emergence of rifampin-resistant staphylococci after rifaximin administration in cirrhotic patients.

Objectives: Rifaximin, a poorly absorbed antibiotics, has gut-specific therapeutic effects. Although frequently prescribed to manipulate intestinal luminal bacterial population in various diseases, the possible induction of antibacterial cross-resistance to a target pathogen is a major concern in long-term rifaximin administration. We aimed to evaluate whether rifampin-resistant staphylococci could evolve after rifaximin treatment in cirrhotic patients.

Multidisciplinary Approach to Refractory Upper Gastrointestinal Bleeding: Case Series of Angiographic Embolization.

Although medical and endoscopic hemostasis is now considered as the first-line therapy for nonvariceal upper gastrointestinal (UGI) bleeding, refractory bleeding still occurs in 5%-10% of the patients. In these patients, transcatheter arterial embolization (TAE) or surgery is required, but research on embolization for unmanageable UGI bleeding in Korea is scanty. We reviewed the medical records of 518 patients who underwent endoscopic hemostasis during 4 years.

Background Colonic 18F-Fluoro-2-Deoxy-D-Glucose Uptake on Positron Emission Tomography Is Associated with the Presence of Colorectal Adenoma.

18F-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) scan is used to evaluate various kinds of tumors. While most studies on PET findings of the colon focus on the colonic uptake pattern, studies regarding background colonic uptake on PET scan are rare. The purpose of this study was to identify the association between the background colonic uptake and the presence of colorectal adenoma (CRA), which is a frequent precancerous lesion.

Clinical Dimensions of Bloating in Functional Gastrointestinal Disorders.

Background/aims: Bloating is common bothersome symptoms and most studies conducted in the Western countries found that bloating was frequently associated with lower gastrointestinal (GI) symptoms but many patients complaint bloating as upper GI symptoms in the clinical setting. This study was conducted to assess the prevalence of bloating, and to identify symptom grouping and finally document the impact of bloating in the diagnosis of functional GI disorders.

Methods: Participants in a comprehensive health-screening cohort were enrolled.

Outcome of active anti-cancer treatment in elderly patients with advanced non-small cell lung cancer: A single center experience.

Background: This study aimed to evaluate the characteristics of active anti-cancer treatment (AAT) compared with best supportive care (BSC) in elderly patients with advanced non-small cell lung cancer (NSCLC).

Methods: A retrospective analysis of 144 patients, aged 70 or older, with stage IIIb/IV NSCLC from 672 patients with confirmed lung cancer, was conducted.

Results: Median age at diagnosis was 77 years and median survival time was five months.

A case of staphylococcal tricuspid valve endocarditis with para-aortic abscess in a patient with bicuspid aortic valve.

Paravalvular abscess is a serious complication of infective endocarditis. The aortic valve and its adjacent ring are more susceptible to abscess formation and paravalvular extension than the mitral valve. A 15-years old patient with bicuspid aortic valve presented with staphylococcal tricuspid valve endocarditis complicated by para-aortic abscess that ruptured into the aortic sinus.
