A 49-year-old woman was referred to our hospital for further treatment due to the suspicion of a submucosal tumor in a routine screening colonoscopy. On colonoscopy, a 1-cm sized subepithelial mass with normal overlying mucosa in the hepatic flexure was found. Endoscopic ultrasonography (EUS) showed a homogenous hypoechoic lesion arising from the second and third layer. We were unable to make a final diagnosis because the lesion showed a small tumor with atypical macroscopic morphology including EUS findings. Therefore, endoscopic submucosal dissection was performed for the diagnostic treatment of the tumor. Submucosal dissection was performed just above the muscle layer, and the tumor was removed completely and reliably without any acute complications such as perforation. Based on histopathological findings, we diagnosed a benign, calcifying fibrous tumor (CFT). The present case is the first report of successful endoscopic diagnosis and treatment of colonic CFT mimicking a submucosal tumor.

Objective: Severe acute cholecystitis is an infectious disease that requires immediate gallbladder drainage. Although percutaneous transhepatic gallbladder drainage (PTGBD) is the most common method of gallbladder drainage, the optimal timing remains unclear. Methods: This study is a retrospective analysis of patients diagnosed with severe acute cholecystitis who underwent PTGBD between July 2018 to June 2021. This study investigated the effect of time from emergency department arrival to PTGBD (tPTGBD) on patient prognosis. Results: Totally, 48 patients were included in this study. Based on the cutoff value calculated using the Youden index, the group with tPTGBD of <5.93 hours had a shorter hospital stay (10 vs. 13.5 days, P=0.021), lower portion of progression (27:5 [15.6%] vs. 7:9 [56.3%], P=0.004), even they had a higher initial SOFA score (6 vs. 4.6, P=0.049). However, no statistical difference was obtained for the length of ICU stay between both groups (1 vs. 2, P=0.617). Conclusion Executing PTGBD to severe acute cholecystitis patients within 5.93 hours after presenting at the emergency department is associated with reduced progression and hospital stay.

Since the existence of cell-free fetal DNA (cff-DNA) in maternal circulation was discovered, it has been identified as a promising source of fetal genetic material in the development of reliable methods for non-invasive prenatal diagnosis (NIPD) of fetal trisomy 21 (T21). Currently, a prenatal diagnosis of fetal T21 is achieved through invasive techniques, such as chorionic villus sampling or amniocentesis. However, such invasive diagnostic tests are expensive, require expert technicians, and have a miscarriage risk approximately 1%. Therefore, NIPD using cff-DNA in the detection of fetal T21 is significant in prenatal care. Recently, the application of new techniques using single-molecular counting methods and the development of fetal-specific epigenetic markers has opened up new possibilities in the NIPD of fetal T21 using cff-DNA. These new technologies will facilitate safer, more sensitive and accurate prenatal tests in the near future. In this review, we investigate the recent methods for the NIPD of fetal T21 and discuss their implications in future clinical practice.

Corpus callsoum (CC) is the largest commissural fiber connecting the cerebral hemispheres. The gender difference in the size or the shape of CC is a long standing dispute. Some reported that adult female CC had more bulbous splenium and larger area considering brain size, but others failed to replicate this findings. There is no definite consensus on sexual dimorphism of CC yet, although extensive studies on sexual dimorphism has been expected to provide a clue to explain sociopsychological differences between male and female. This variable results are attributed to limited number of subjects, measured parameters, and method of measurement. We have employed comprehensive analytic parameters with large subjects to understand gender differences on CC of healthy Korean adults. We have analyzed the magnetic resonance image (MRI) in adults free from neurological disorders. The subjects were composed of 108 young people (3rd decade; male : 51, female : 57). Total area, its 5 sub-areas, linear parameters including height, length, and width and five specific angles of the CC were measured on the midsagittal MR images with NIH Image program (R) (Ver 1.6). The gender differences were observed in the area of splenium and length in the group. The male CC have larger splenium and longer length than female. The angle between neural axis and base of corpus callosum in female was significantly larger than that of male. This study reports not only gender difference of adult CC, but Korean adult standard morphometric data of CC research. These results might serve a useful basic data for various research in the fields of neuroanatomy, neuroradiology, and neuropsychiatry.

Central nervous system toxicity is the most commonly recognized problem during treatment with carbamazepine (CBZ). The most common side effects of CBZ are drowsiness, incoordination, and vertigo. However, unusual conditions such as movement disorders, seizure aggravation, and encephalopathy have also been attributed to CBZ therapy. In case 1, cognitive dysfunction and exacerbation of preexisting gait disturbance were observed in a 63-year-old female who had frontal lobe epilepsy, schizencephaly, and lissencephaly treated with CBZ. The neurological symptoms were resolved 24 hours after the withdrawal of CBZ and induced with the reintroduction of CBZ. In case 2, myoclonic jerks occurred in a 37-year-old female when CBZ was readministered after a 4-day-withdrawal period of CBZ. The myoclonic jerks disappeared 12 days after CBZ was discontinued. In both cases, plasma CBZ levels were within the therapeutic range. We report two cases with encephalopathy and myoclonic jerks as unusual side effects of CBZ, with the plasma levels of CBZ being within the therapeutic range.

PURPOSE: To report the initial clinical experience with single-incision laparoscopic gastric wedge resection for submucosal tumors. MATERIALS AND METHODS: The medical records of 10 patients who underwent single-incision laparoscopic gastric wedge resection between July 2009 and March 2011 were reviewed retrospectively. The demographic data, clinicopathologic and surgical outcomes were assessed. RESULTS: The mean tumor size was 2.5 cm (range, 1.2~5.0 cm), and the tumors were mostly located on the anterior wall (4/10) or along the greater curvature (4/10), of the stomach. Nine of ten procedures were performed successfully, without the use of additional trocars, or conversion to laparotomy. One patient underwent conversion to multiport laparoscopic surgery, to get simultaneous cholecystectomy safely. The mean operating time was 66.5 minutes (range, 24~132 minutes), and the mean postoperative hospital stay was 5 days (range, 4~7 days). No serious perioperative complications were observed. Of the 10 submucosal tumors, the final pathologic report revealed 5 gastrointestinal stromal tumors, 4 schwannomas, and 1 heterotopic pancreas. CONCLUSIONS: Single-incision laparoscopic gastric wedge resection for gastric submucosal tumors is feasible and safe, when performed by experienced laparoscopic surgeons. This technique provides favorable cosmetic results, and also short hospital stay and low morbidity, in carefully selected candidates.

The purpose of this study was to develop a muffin containing dried leek powder. The complete analysis was conducted using the Design Expert 7 program (Stat - Easy Co., Minneapolis, MN, USA). The leek muffins were produced with varying amounts of leek powder (A), sugar (B), and butter (C). According to response surface methodology (RSM), there were 16 experimental points, including two replicates. The leek muffin formulation was optimized using rheology and sensory analyses. For the results, a quadratic model was applied in determining lightness, volume, hardness, and sensory characteristics, including flavor, texture, and overall quality; redness and height were represented by a linear model. Lightness decreased and redness increased with increasing amounts of leek powder (p<0.001). In addition, hardness displayed significant differences (p<0.001) with increasing amounts of leek powder. The sensory evaluation results showed significant differences for color, flavor, texture, and overall quality (p<0.05). Based on the numerical and graphical methods, the optimal formulation was determined as 8.30 g of leek power, 88.37 g of sugar, and 81.70 g of butter.

Thrombocytopenia is a common manifestation of rickettsial disease. However, the pathogenesis of thrombocytopenia in many rickettsial diseases is poorly understood. Thrombocytopenia may be associated with consumption due to widespread endothelial damage or disseminated intravascular coagulation, hypersplenism, decreased marrow production, and immune-mediated platelet destruction. Some reports have found anti-platelet antibodies detected in thrombocytopenic patients with rickettsial disease. In addition to thrombocytopenia, facial palsy and Guillain-Barre syndrome were also reported as immune-mediated phenomena in scrub typhus. Here we report a case diagnosed as immune-mediated thrombocytopenia associated with scrub typhus. This is the first report of immune thrombocytopenic purpura (ITP) associated with scrub typhus in Korea. The patient exhibited eschar with a high titer of anti-tsutsugamushi antibody, thrombocytopenia, severe gastrointestinal hemorrhage, and purpura on the lower region of both legs. After steroid treatment, the sustained thrombocytopenia recovered.
