Xanthogranulomatous cholecystitis is an uncommon inflammatory disease of the gall baldder characterised by a focal or diffuse destructive inflammatory process. The pathogenesis is uncertain, but an inflammatory response to extravasated bile due to acute inflammation and obstruction is likely. Macroscopically, the gall bladder wall is invariably thickened, and extensive adhesions to adjacent organs are frequent. Clinically, xanthogranulomatous cholecystitis can mimic gall bladder carcinoma and radiologic differential diagnosis is extremely difficult. Fistula to skin and duodenum was reported. We report the first case of cholecysto-colonic fistula due to xanthogranulomatous cholecystitis.

Simultaneous or subsequent bilateral thalamic hemorrhagic events have ranged from 12 to 19 in prior reports, with a time lag between bilateral thalamic hemorrhage of up to two days. Herein, we report the first case of delayed (17 days) consecutive contralateral thalamic hemorrhage after spontaneous first thalamic hemorrhage. A 65-year-old female initially presented with a drowsy mentality with a left-side motor weakness (grade II/III). Brain computed tomography (CT) demonstrated right side thalamic and intraventricular hemorrhage. She regained alertness with mild residual motor weakness (grade III/IV) under medical management. Seventeen days later, a sudden and generalized tonic-clonic seizure developed. Brain CT scans revealed a new contralateral thalamic hemorrhage coincident with microbleeds. Neurologic status remained unchanged, consisting of a stuporous mentality with quadriparesis of grade II/II. We report the first case of delayed consecutive contralateral thalamic hemorrhage up to 17 days after first thalamic hemorrhage. The case highlights the need for close monitoring of patients with thalamic hemorrhage who experience microbleeds on the contralateral side, due to the possibility of delayed hemorrhage.

Symptomatic muscular rings are extremely rare, and some authors have even disputed their existence. The lower esophageal muscular ring, or A ring, located about 2cm proximal to the squamocolumnar junction and are covered by squamous epithelium. These rings consist of an annular narrowing of hypertrophic muscular tissue in the esophageal body. Recently, we experienced 2 cases of symptomatic muscular ring of the esophagus and the findings. Case 1) A 52 year-old male with dysphagia, chest pain and regurgitation for several years, had esophagogram, endoscopy, esophageal motility studies and chest CT. Under the diagnosis of esophageal muscular ring, the patient had pneumatic baUoon dilatation (3.0 cm in diameter, Rigiflex), under which the patient experienced perforation of the lower esophagus and required surgery. We confirmed muscular ring of the esophagus as shown by a thickened muscularis propria layer, without other pathologic findings. Case 2) A 60 year-old male complaining of intermittent dysphagia, had esophagogram, endoscopy, esophageal motility studies and EUS. Under the diagnosis of esophageal muscular ring, he is now being treated with calcium channel blocker and nitrate, and has experienced minimal symptom improvement. We report 2 cases of symptomatic muscular ring of low esophagus with review of literature.

Cystic dilatation of the biliary tree, so called choledochal cyst, is an uncommon disease and is not uncommonly associated with carcinoma. The most symptoms on. presentation are abdominal pain, weight loss, jaundice, and palpable mass. The prognosis of these lesions is dismal. Recently we experienced a case of carcinoma arising in a choledochal cyst in 27-year-old male complaining jaundice and fever. ERCP revealed marked dilated the CBD and obstruction of the proximal portion of the CHD. A computerized tomographic scan and percutaneous cholangiogram showed cystic dilatation of both intrahepatic ducts and solid mass in the left hepatic duct. The patient was treated with surgical resection. Pathologic studies disclosed an adenosquamous carcinoma.

Esophageal duplication cysts account for a very small percentage of benign esophageal tumors and are infrequently symptomatic. Esophageal duplication cysts result from aberrant alignment of the normal vacuolization process that produce the esophageal lumen in the 5th to 8th week of embryonic life. Complications most often are bleeding into or infection of cysts. Recently, we experienced a case of esophageal duplication cyst complicated with intramural huge hematoma and the cause of hematoma could not be identified. We report it with a review of literatures.

PURPOSE: The aim of this study was to assess the risk factors of prolonged hemodynamic instability (HDI) after carotid angioplasty and stenting (CAS). Herein, a simplified predictive scoring system for prolonged HDI is proposed. MATERIALS AND METHODS: Sixty-six patients who had CAS from 2011 to 2016 at a single institution were evaluated. Prolonged HDI was defined as systolic blood pressure >160 mm Hg or <90 mm Hg or heart rate <50 beats/min, lasting over 30 minutes despite medical treatments. For the study, clinical data and radiologic data, including plaque morphology and stenosis were analyzed. RESULTS: Prolonged HDI was observed in 21 patients (31.8%). Multivariable analysis revealed that calcification (OR, 6.726; p=0.006), eccentric stenosis (OR, 3.645; p=0.047) and extensive plaque distribution (OR, 7.169; p=0.006) were related to prolonged HDI. According to these results, a simplified scoring scale was proposed based on the summation of points: 2 points for calcified plaque, 2 points for extensive plaque distribution, and 1 point for eccentric stenosis. The percentages of prolonged HDI according to the total score were as follows: score 0, 8.7%; score 1, 20.0%; score 2, 38.5%; score 3, 72.7%; score 4, 66.7%; score 5, 100%. From the analysis, the total score in patients with prolonged HDI was significantly higher than those without prolonged HDI (p<0.001). CONCLUSION: Prolonged HDI can be associated with calcification of plaque, eccentric stenosis and extensive plaque distribution, and a simplified scoring system enables prediction of prolonged HDI according to our cohort.

Pseudoachalasia is a distinct clinical entity that mimics idiopathic achalasia. However, the pathophysiology of pseudoachalasia is debated. Although neoplastic involvement of the distal esophagus is the most common cause of pseudoachalasia, benign disease of the distal esophagus could result in clinical entity of pseudoachalasia as well. We report a case of pseudoachalasia following a benign esophageal stricture by gastroesophageal reflux disease, which needs to differentiate from malignant esophageal strictures.

Previously, we reported the concept of a cloud-based telemedicine platform for patients with intracerebral hemorrhage (ICH) at local emergency rooms in rural and medically underserved areas in Gangwon state by combining artificial intelligence and remote consultation with a neurosurgeon. Developing a telemedicine ICH treatment protocol exclusively for doctors with less ICH expertise working in emergency rooms should be part of establishing this system. Difficulties arise in providing appropriate early treatment for ICH in rural and underserved areas before the patient is transferred to a nearby hub hospital with stroke specialists. This has been an unmet medical need for decade. The available reporting ICH guidelines are realistically possible in university hospitals with a well-equipped infrastructure. However, it is very difficult for doctors inexperienced with ICH treatment to appropriately select and deliver ICH treatment based on the guidelines. To address these issues, we developed an ICH telemedicine protocol. Neurosurgeons from four university hospitals in Gangwon state first wrote the guidelines, and professors with extensive ICH expertise across the country revised them. Guidelines and recommendations for ICH management were described as simply as possible to allow more doctors to use them easily. We hope that our effort in developing the telemedicine protocols will ultimately improve the quality of ICH treatment in local emergency rooms in rural and underserved areas in Gangwon state.

BACKGROUND AND OBJECTIVES: The burden of heart failure has increased in Korea. This registry aims to evaluate demographics, clinical characteristics, management, and long-term outcomes in patients hospitalized for acute heart failure (AHF). SUBJECTS AND METHODS: We prospectively enrolled a total of 5625 consecutive subjects hospitalized for AHF in one of 10 tertiary university hospitals from March 2011 to February 2014. Descriptive statistics were used to determine the baseline characteristics of the study population and to compare them with those from other registries. RESULTS: The mean age was 68.5±14.5 years, 53.2% were male, and 52.2% had de novo heart failure. The mean systolic and diastolic blood pressures were 131.2±30.3 mmHg and 78.6±18.8 mmHg at admission, respectively. The left ventricular ejection fraction was ≤40% in 60.5% of patients. Ischemia was the most frequent etiology (37.6%) and aggravating factor (26.3%). Angiotensin converting enzyme inhibitors/angiotensin receptor blockers, beta-blockers, and aldosterone antagonists were prescribed in 68.8%, 52.2%, and 46.6% of the patients at discharge, respectively. Compared with the previous registry performed in Korea a decade ago, extracorporeal membrane oxygenation (ECMO) and heart transplantation have been performed more frequently (ECMO 0.8% vs. 2.8%, heart transplantation 0.3% vs. 1.2%), and in-hospital mortality decreased from 7.6% to 4.8%. However, the total cost of hospital care increased by 40%, and one-year follow-up mortality remained high. CONCLUSION: While the quality of acute clinical care and AHF-related outcomes have improved over the last decade, the long-term prognosis of heart failure is still poor in Korea. Therefore, additional research is needed to improve long-term outcomes and implement cost-effective care.
