Listeria grayi is a catalase-positive, non-spore forming, and glucose-fermenting Gram-positive rod. L. grayi is widely distributed in environments such as soil, water and fresh food. Human infection by L. grayi is very rare, and there have been no cases reported in Korea, and only two cases worldwide. Dermabacter hominis is a relatively new species belonging to the coryneform bacteria and is a component of the normal human skin flora. D. hominis is a non-motile, glucose-fermenting, Gram-positive rod that has similar biochemical characteristics to L. grayi. The authors of the present study report a case initially misidentified as L. grayi via a traditional morphological and biochemical identification method but that was subsequently confirmed as D. hominis using sequence analysis of 16S rRNA.

Mucin-producing tumors of the pancreas were first reported by Ohhashi and Takagi in 1980. Since then, many cases of intraductal papillary mucinous tumor (IPMT) of the pancreas, which is almost homonymous to mucin-producing tumors of the pancreas, have been reported. IPMTs are generally regarded as tumors with a favorable prognosis. Some IPMTs have invasiveness and this is always associated with a poor prognosis. Most IPMTs arise from the main pancreatic duct and IPMTs arising from the accessory pancreatic duct are relatively rare. Only 6 cases have been reported in the literature so far. Our patient was a 43-year old man who was admitted to the hospital due to recurrent pancreatitis. An endoscopic retrograde pancreatography revealed a patulous minor papilla orifice extruding mucin and a cystic lesion in a branch of the accessory duct. A pancreaticoduodenectomy was performed and a pathologic examination of the resected specimen showed intraductal papaillary mucinous neoplasm, low grade malignancy, in the accessory pancreatic duct and its branch. We herein report this interesting case with a review of the literature.

Primary thyroid lymphomas constitute of up to 5% of all thyroid malignancies. Recently, mucosa-associated lymphoid tissue (MALT) lymphoma are relatively recognized as a B cell subset of non-Hodgkin's lymphoma. MALT-lymphomas are thought to develop from acquired lymphocytic tissue during the course of a chronic inflammatory or autoimmune process. In the thyroid , which is normally devoid of lymphocytic tissue, chronic autoimmune thyroiditis (Hashimoto's disease) has been associated with an increased risk of lymphoma, including MALT type. The clinical presentations include the enlarging of the neck mass, dysphagia, hoarsenes and choking or cold thyroid nodule. We report a case of MALToma of the thyroid accompanied by Hashimoto's thyroiditis with a review of the literature.

PURPOSE: To evaluate the efficiency of the electronic foot function index (eFFI) through a prospective, random based, multi-institutional study. MATERIALS AND METHODS: The study included 227 patients ranging in age from 20 to 79 years, visited for surgery in different 15 institutes, and agreed to volunteer. The patients were assigned randomly into a paper-based evaluated group (n=113) and tablet-based evaluated group (n=114). The evaluation was done on the day of hospital admission and the method was changed on the second day of surgery and re-evaluated. PADAS 2.0 (https://www.proscore.kr) was used as an electronic evaluation program. RESULTS: There were no differences in age and sex in both groups. The intraclass correlation coefficient (ICC) evaluation revealed an eFFI ICC of 0.924, showing that both results were similar. The evaluation time was shorter in the tablet-based group than the paper-based group (paper vs tablet, 3.7±3.8 vs 2.3±1.3 minutes). Thirty-nine patients (17.2%) preferred to use paper and 131 patients (57.7%) preferred the tablet. Fifty-seven patients (25.1%) found both ways to be acceptable. CONCLUSION: eFFI through tablet devices appears to be more constant than the paper-based program. In addition, it required a shorter amount of time and the patients tended to prefer the tablet-based program. Overall, tablet and cloud system can be beneficial to a clinical study.

BACKGROUND: Vitamin K antagonist (VKA) to prevent thromboembolism in non-valvular atrial fibrillation (NVAF) patients has limitations such as drug interaction. This study investigated the clinical characteristics of Korean patients treated with VKA for stroke prevention and assessed quality of VKA therapy and treatment satisfaction. METHODS: We conducted a multicenter, prospective, non-interventional study. Patients with CHADS2 ≥ 1 and treated with VKA (started within the last 3 months) were enrolled from April 2013 to March 2014. Demographic and clinical features including risk factors of stroke and VKA treatment information was collected at baseline. Treatment patterns and international normalized ratio (INR) level were evaluated during follow-up. Time in therapeutic range (TTR) > 60% indicated well-controlled INR. Treatment satisfaction on the VKA use was measured by Treatment Satisfaction Questionnaire for Medication (TSQM) after 3 months of follow-up. RESULTS: A total of 877 patients (age, 67; male, 60%) were enrolled and followed up for one year. More than half of patients (56%) had CHADS2 ≥ 2 and 83.6% had CHA2DS2-VASc ≥ 2. A total of 852 patients had one or more INR measurement during their follow-up period. Among those patients, 25.5% discontinued VKA treatment during follow-up. Of all patients, 626 patients (73%) had poor-controlled INR (TTR < 60%) measure. Patients' treatment satisfaction measured with TSQM was 55.6 in global satisfaction domain. CONCLUSION: INR was poorly controlled in Korean NVAF patients treated with VKA. VKA users also showed low treatment satisfaction.
