Successful endoscopic treatment of an obstructing gastric antral web in a paediatric patient: A case report.

Gastric antral web (GAW) is a rare anomaly of the gastric antrum and can result in gastric outlet obstruction. Currently, endoscopic treatment of GAW is considered challenging due to high technical requirements and restenosis. Herein, we present a rare case of a paediatric patient with GAW cured by endoscopic transection and partial resection of the web. An 8-year-old boy was admitted because of a 9-month history of postprandial fullness and intermittent non-bilious vomiting of gastric contents. On performing upper gastrointestinal contrast and gastroscopy, the diagnosis of GAW was confirmed. Then, three electroincisions were performed in a radial fashion. Moreover, about a third of the web located in the larger curvature was resected. On follow-up for 6 months, the patient was completely relieved of the postprandial fullness and non-bilious vomiting. Hence, endoscopic treatment for GAW was considered safe and effective for this case. Furthermore, partial resection of the web contributed in avoiding restenosis.

Intestinal neuronal dysplasia presenting as psoas abscess: A case report.

Background: Intestinal neuronal dysplasia (IND) is a rare condition mainly affecting the children. Constipation and abdominal distension have been reported as common manifestations. In addition, the reports about adult cases are scarce. Case report: A 31-year-old man presented with pain in his left hip and intermittent fever for 1 month. The whole abdomen CT and pelvic contrast-enhanced MRI revealed a left psoas abscess (PA). The patient has been given anti-infective treatment and underwent CT-guided drainage of left PA with a temporary drain. But the patient's condition did not improve significantly. Then, the colonoscopy revealed that it may be the PA secondary to inflammatory bowel disease. But the pathology was not in line with inflammatory bowel disease. We finally performed an ileostomy surgery and took the whole layer of intestinal wall for biopsy. The pathological result revealed that a large number of proliferative ganglion cells and circuitous hyperplastic nerve fibers were found in the submucosa and muscular layer of the intestinal wall. Given pathological results and clinical manifestations, the patient was diagnosed with IND-B. Conclusion: In this case, we first report an extremely rare case of adult IND manifesting as PA. So, this unusual case provides a new supplement to adult cases of IND.

Isolation and characterization of microsatellite markers for Dipteronia dyerana (Sapindaceae), an endangered endemic species in China.

PREMISE OF THE STUDY: Microsatellite markers were developed for Dipteronia dyerana, an endangered endemic species in China, to study the population genetics of this species. METHODS AND RESULTS: Using the Fast Isolation by AFLP of Sequences Containing repeats (FIASCO) protocol, 12 microsatellite markers that were successfully amplified showed polymorphism when tested on 31 individuals from two populations in the counties of Wenshan and Mengzi. Overall, the number of alleles per locus ranged between seven and 25, with an average of 12.3. Nine of these markers were able to be amplified in D. sinensis. CONCLUSIONS: These microsatellite markers should facilitate further studies on the population genetics and the reproductive ecology of Dipteronia.
