Stress induced cardiomyopathy is characterized by transient systolic dysfunction of the apical segment of the left ventricle, in the absence of obstructive coronary artery disease. The clinical presentation of stress induced cardiomyopathy is similar to that of an acute myocardial infarction. Onset of stress induced cardiomyopathy is frequently triggered by intense emotional or physical stress. Hypoglycemia is one type of physical stress that causes stress induced cardiomyopathy. We report on a case of this syndrome associated with hypoglycemia.

There are many known renal complications of rheumatoid arthritis. These complications can develop by the extraarticular aspect of rheumatoid arthritis or the use of disease modifying antirheumatic drugs or pain-killer. The most common renal disease induced by use of disease modifying antirheumatic drugs is membranous nephropathy. We report on a case of bucillamine induced nephropathy with prominent proteinuria and hypoalbuminemia. The renal biopsy result was stage I to II membranous nephropathy. After withdrawal of bucillamine the proteinuria improved and hypoalbuminemia recovered. Even in cases of accompanying prominent proteinuria and hypoalbuminemia, bucillamine nephropathy can be treated with withdrawal of bucillamine and immunosuppressant drugs are not required.

Background/Aims: In this study, we compared the efficacy and safety of etomidate with those of propofol or midazolam for themaintenance of sedation during endoscopy. Methods: The study enrolled patients who underwent sedative endoscopy in our hospital and divided them into three groups. Patients in each group were administered midazolam as induction therapy and were subsequently administered either midazolam(M + M group), propofol (M + P group), or etomidate (M + E group) as maintenance medication. The primary outcome was overallcardiovascular and respiratory adverse events. Results: In total, 105 patients who underwent sedative endoscopic examination were enrolled. The outcomes related to the procedureand sedation were not significantly different among the groups. Overall cardiovascular and respiratory adverse events were observedin 9 patients (25.7%) in the M + M group, 8 patients (23.5%) in the M + P group, and 10 patients (27.8%) in the M + E group. Thelogistic regression analysis revealed that etomidate use was not an independent risk factor for overall cardiovascular and respiratoryadverse events. Conclusions: The outcomes following the use of etomidate for maintenance after induction with midazolam for sedation in uppergastrointestinal endoscopy were not inferior to those following midazolam or propofol use from the perspectives of safety andefficacy.

Gastric bezoars are concretion of undigested material in the gastrointestinal tract. In the past, gastric bezoars were generally treated with surgical management. Recently, the efficacy of oral intake or endoscopic injection therapy with Coca-Cola has been reported. We report a case of a 47-year-old-man with huge gastric bezoar (4×2.5cm) that was successfully removed by endoscopic fragmentation with Coca-Cola injection. Compared with a single endoscopic fragmentation therapy, the combination therapy with Coca-Cola injection shortened the procedure time and reduced the complication associated with fragmented bezoar.

Background/Aims: The molecular underpinnings of colorectal cancer (CRC) vary according to the tumor location. The advantages of a palliative primary tumor resection in patients with metastatic CRC are controversial. This study examined the survival outcomes of a palliative primary tumor resection based on the tumor location in patients with metastatic CRC. Methods: The medical records of 600 patients diagnosed with metastatic CRC between January 2000 and June 2018 were reviewed retrospectively. Patients undergoing surgery for both the primary tumor and metastatic lesions were excluded. The clinical factors affecting the long-term outcomes were evaluated according to the primary tumor location, and the long-term survival was compared between patients with and without a palliative primary tumor resection. The data were analyzed using the Kaplan-Meier estimator and multivariate Cox regression models. Results: The median follow-up duration was 18 months (interquartile range, 10-28). Patients with right-sided CRC had a poor overall- and progression-free survival compared to those with left-sided CRC. In multivariate Cox regression analysis, the palliative primary tumor resection was an independent prognostic factor predicting better overall survival in patients with metastatic CRC, regardless of the primary tumor location. Conclusions: The primary tumor location influences the prognosis, and that a primary tumor resection can improve the overall survival in patients with metastatic CRC, regardless of the primary tumor location.
