A 12-year-old, castrated male, mixed dog presented with a history of gradual abdominal distention for a year and anorexia recently, with abdominal radiographs showing a gastric pylorus distention. A solitary, pedunculated, heterogeneous mass arising from the mucosal layer in the pylorus with intact wall layers was identified during ultrasound and computed tomography. The gastric muscular layer was evenly thick. After surgical excision of the mass, histological examination confirmed hypertrophic pyloric gastropathy with polypoid growth and Helicobacter spp. infiltrating the gastric mucosal epithelium. This is the first reported diagnostic imaging case of hypertrophic pyloric gastropathy with Helicobacter spp. in a dog.

Acute infectious mononucleosis, caused by Epstein-Barr virus(EBV), is a self limited lymphoproliferative illness that is common in adolescents and young adults. It shows many complications in multiple organ systems, but the hepatobiliary and the respiratory complication is uncommon. We report a case with thickened gallbladder wall and pneumonia as complications of acute infectious mononucleosis in a child. Also the related literature were reviewed. A 4 year old boy presented with a history of high fever, cough, and abdominal distension for 20days. Physical Examination revealed audible crackles in whole lung field and gross hepatomegaly. Chest X-ray showed pneumonia and liver function tests were abnormal. Ultrasonography and computed tomography revealed a thickened gallbladder wall and hepatosplenomegaly. The diagnosis of primary Epstein-Barr viral infection was eventually made by specific serologic tests. The patients's fever subsided 6 weeks later and pneumonia was recovered around this time. Liver function tests returned near normal 2 months later and ultrasonography of gallbladder was normal at this time.

The purpose of this experiment is to evaluate of optimized FS techniques for T2 weighted abdominal MRI compared of TSE-SPIR fat suppression and GE-PROSET fat suppression. All MR examinations were performed on a 1.5 T(Philips, Medical System, Achieva) scanner using 16 channel mult-coils. All images were performed in the axial plane using TSE-SPIR and GE-PROSET. The mean SNRs of the retroperitoneal and mesenteric fat for TSE-SPIR and GE-PROSET were 31.50, 4.15 and 32.39, 7.03. The mean CNRs of the bowel and retroperitoneal, mesenteric fat for TSE-SPIR and GE-PROSET were 52.69, 74.54 and 26.12, 68.78). The delineation of bowel wall margins with TSE-SPIR(2.4) and GE-PROSET(1.8) were significantly improved using TSE-SPIR. The delineation of pancreas wall with TSE-SPIR(1.90), GE-PROSET(2.80) were significantly improved using GE-PROSET. In conclusion, TSE-SPIR fat suppression was superior to GE-PROSET fat suppression in T2 WI FS abdominal MRI.

We prepared an anti-adhesion membrane made of sodium hyaluronate/sodium carboxymethylcellulose (HA/CMC) and evaluated its effectiveness for adhesion prevention in a rat model. The anti-adhesion membrane was prepared by lyophilizing HA/CMC solution and cross-linking properly with 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDAC). In a cecum/abdominal wall abrasion model of Sprague-Dawley rat, cecal serosa and abdominal wall were abraded in $1\times2\;(cm^2)$ with a bone burr after peritoneal midline incision and sutured at 3 points around the injured surface. The denuded cecum was covered with HA/CMC membrane (experimental group), or nothing (control group) and apposed to the abdominal wall. Most of the control group represented 3 or more of adhesion grade at POD 7, 14, 21, and 28, whereas $60\~70\%$ of the experimental group was 2 or less of adhesion grade at 14, 21, and 28. It was similar in the adhesion strength. In a general manner, the adhesion grade and strength showed gradual increasing until POD 14, almost same or a little increasing POD 21, but decreasing POD 28. Also the control group was much higher in adhesion grade, strength, and area than the experimental group. It is expected that the anti-adhesion membrane will have a good clinical result in postoperative adhesion prevention.

Objective: To provide an evidence-based guide for the MRI interpretation of complete tumor response after neoadjuvant chemoradiation therapy (CRT) for rectal cancer using visual assessment on T2-weighted imaging (T2) and diffusion-weighted imaging (DWI). Materials and Methods: PubMed MEDLINE, EMBASE, and Cochrane Library were searched on November 28, 2019 to identify articles on the following issues: 1) sensitivity and specificity of T2 or DWI for diagnosing pathologic complete response (pCR) and the criteria for MRI diagnosis; 2) MRI alone vs. MRI combined with other test(s) in sensitivity and specificity for pCR; and 3) tests to select patients for the watch-and-wait management. Eligible articles were selected according to meticulous criteria and were synthesized. Results: Of 1615 article candidates, 55 eligible articles (for all three issues combined) were identified. Combined T2 and DWI performed better than T2 alone, with a meta-analytic summary sensitivity of 0.62 (95% confidence interval [CI], 0.43-0.77; I² = 80.60) and summary specificity of 0.89 (95% CI, 0.80-0.94; I² = 92.61) for diagnosing pCR. The criteria for the complete response on T2 in most studies had the commonality of remarkable tumor decrease to the absence of mass-like or nodular intermediate signal, although somewhat varied, as follows: (near) normalization of the wall; regular, thin, hypointense scar in the luminal side with (near) normal-appearance or homogeneous intermediate signal in the underlying wall; and hypointense thickening of the wall. The criteria on DWI were the absence of a hyperintense signal at high b-value (≥ 800 sec/mm²) in most studies. The specific algorithm to combine T2 and DWI was obscure in half of the studies. MRI combined with endoscopy was the most utilized means to select patients for the watch-and-wait management despite a lack of strong evidence to guide and support a multi-test approach. Conclusion: This systematic review and meta-analysis provide an evidence-based practical guide for MRI assessment of complete tumor response after CRT for rectal cancer.

The purpose of this study is for fundamental research of meditation smart wear for physical and mental healing, and researching method for monitoring phase of meditation through textile by measuring the number of abdominal respiration when meditating. For this purpose, the research implemented Single Wall Carbon Nano-Tube (SWCNT) based strain gauges type textile sensor, considered reliability and validity of respiratory sensing, and analyzed efficiency of respiratory sensing based on body parts comparatively. The first preliminary experiment was to evaluate the performance of textile sensor through abdominal model dummy which open and shut of 5 cm repeatedly for 2 minutes at the rate of 0.1Hz in order to simulate abdominal respiration. It concluded signal efficiency between reference sensor(BIOPAC) and textile respiratory sensor appears statistically significant (p<0.001). The second experiment were conducted with 4 subjects doing abdominal respiration under same conditions, and after comparing the signal values between two sensors from 4 attached locations(around center and sides of omphali and phren), center of omphali and sides of phren were selected as suitable location for measuring meditational breathing as they showed large and stable signals. In result, this research aimed for implementing of the textile sensor for sensing meditational breathing of long respiration cycle, review of reliability and validity for sensing number of meditational respiration with the sensor and consideration of sensing efficiency by sensing location on body parts.

From June 1987 to December 1994, 372 patients underwent operation for resection of esophageal cancer, and 48 patients with metastasis to distant abdominal lymph nodes were analyzed.. The primary tumors were located predominantly in lower thoracic esophagus(n=29). The location of involved lymph nodes were celiac L/N(n=45), common hepatic L/N(n=4), paraaortic L/N(n=l), and retropancreatic L/N(n=l). Most tumors penetrated the esophageal wall(T3,T4, n=43), metastased to regional L/N(N1, n=41), but a few tumors were limited to the esophageal wall(T1,T2, n=5), metastased to distant abdominal L/N without metastasis to regional L/N(NO, n=7). Resectability rate was 87.5%(42/48), and complete resection was possible in 31 patients(64.6%). The most frequent cause of incomplete resection and unresectability was unresectable T4 lesions(n=8), extranodal invasion(n=7). Overall operative mortality and morbidity was 4.2%, 22.9%, and resection mortality was 4.8%. Adjuvant therapy was given to 27 patients, and postoperative follow-up was possible in all patients(median follow-up, 32 months). The 1 year and 3 year survival for resection group was 54.0%, 18.1%(median, 386 days) including operative deaths. Our results suggest that resection of the esophageal cancer with metastasis to distant abdominal lymph nodes(M1LYN) can be done with acceptable mortality and morbidity, and may playa role in long-term survival in carefully selected patients because prognosis is dismal in unresectable esophageal cancer. We recommend that lymph nodes around celiac axis be dissected thoroughly for exact staging and possible prolongation of survival, and multimodality therapy as necessary because most patients with M1(LYN) esophageal cancer do poorly with only primay surgical treatment.
