Duodenal diverticula are frequently observed in upper gastrointestinal endoscopies or upper gastrointestinal series. Most duodenal diverticula are asymptomatic, and complications are rare, however, diverticula occasionally result in diverticulitis, hemorrhage, obstruction, perforation, or sepsis. Most ingested foreign bodies are passed spontaneously and evacuated through gastrointestinal movement, but, if these foreign bodies are sharp and become impacted in a pathological lesion, such as a diverticulum, the risk of complications can be very high. In this paper, we report on a case of duodenal diverticulitis resulting from impacted bone-like food material. In this case, the food-material-induced diverticulitis showed spontaneous improvement through supportive care.

Melioidosis, an infectious disease caused by the facultative intracellular gram-negative bacillus Burkholderia pseudomallei, is geographically restricted to Southeast Asia and Northern Australia. It commonly affects patients with underlying medical disease, such as diabetes mellitus or renal failure. In South Korea, only six cases of melioidosis have been reported in the literature. However, none of the patients had chronic kidney disease. We report on a case of melioidosis presenting as septicemic pneumonia in a 48-year old man undergoing hemodialysis. He was a returning traveler from Thailand.

The aim of this study was to evaluate the efficacy of tenofovir in HBV patients at 12 months after treatment. A total of 122chronic hepatitis B patients who took tenofovir for at least 12 months were enrolled. We measured ALT levels, HBeAg, anti-HBe, HBV DNA, and serum creatinine at six and 12 months after treatment. The virological response rate at six and 12 months after treatment in naïve patients was 27.1% and 41.7%, respectively. High virological response rate at six and 12months after treatment showed an association with initial low HBV DNA titer and initial negative HBeAg status.
