Spontaneous arterial bleeding has been reported rarely. In a patient consuming heavy amounts of alcohol with alcoholic liver cirrhosis, spontaneous bleeding can be evoked by thrombocytopenia, altered platelet function, and shear stress on fully dilated arteries by portal hypertension. Alcohol consumption itself can also predispose a patient to bleeding by influencing the aggregation and activation of platelets, and altering the coagulation and fibrinolysis pathway. All of these mechanisms could cause patients with alcoholic liver cirrhosis to bleed spontaneously; however, conditions inducing peripheral arterial bleeding are very rare. Here, we report three cases of spontaneous arterial bleeding in patients with liver cirrhosis consuming heavy amounts of alcohol. All of the patients bled without any physical trauma, and the involved arteries were the intercostal arteries in two cases and a gastroduodenal artery in the other case. The patients were treated by angiographic embolization. One expired due to recurrence of arterial bleeding despite repeated angiographic embolization and massive transfusion.

The purpose of this study is to investigate a usability assessment to evaluate the safety and satisfaction of ‘Smart speech’, a speech therapy solution program so that speech therapy can be easily performed at home. Smart speech program consists of software, laptop and microphone, and includes 59 training games for oral exercise, breathing training and voice training. We evaluated whether the events occurring in the process of using the product were properly performed when the product manual was provided to 5 ordinary people without experience in speech rehabilitation and allowed to use easily. In addition, we investigated the survey of safety and satisfaction in the product. As a result of the experiment, it showed a 100% success rate in 23 tasks with 3 scenarios. In addition, in the satisfaction survey result, we found that more than 80% of the 15 items were satisfied with the convenience of use, treatment utilization, and overall satisfaction with the program. In the future, we thought that a speech therapy programs could be used as basic data to develop speech therapy medical devices for the speech-impaired using the results.

Eosinophilic esophagitis (EoE) with adults, as a new disease emerging during the last decade, is a clinicopathologic disorder of the esophagus characterized by a dense esophageal eosinophilic infiltration and typical esophageal symptoms. As numerous studies about EoE had been reported during last several years, updated consensus of EoE was reported in July 2011. The conceptual definition of EoE is coming. EoE is defined as a chronic, immune/antigen-mediated esophageal disease characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil-predominat inflammation. Other important addition is genotyping feature that implicates thymic stromal lymphopoietin genes or filagrrin as EoE susceptibility genes. The majority of patients has the concurrent allergic disease, especially food or aeroallergen sensitization. Main therapeutic options include topical steroids and dietary modification. Recent issues of EoE include a new concept for proton pump inhibitor- responsive esophageal eosinophilia that it should be excluded to diagnose EoE. (Korean J Gastroenterol 2012;60:3-12)
