The H9N2 avian influenza (AI) has become endemic in poultry in many countries since the 1990s, which has caused considerable economic losses in the poultry industry. Considering the long history of the low pathogenicity H9N2 AI in many countries, once H9N2 AI is introduced, it is more difficult to eradicate than high pathogenicity AI. Various preventive measures and strategies, including vaccination and active national surveillance, have been used to control the Y439 lineage of H9N2 AI in South Korea, but it took a long time for the H9N2 virus to disappear from the fields. By contrast, the novel Y280 lineage of H9N2 AI was introduced in June 2020 and has spread nationwide. This study reviews the history, genetic and pathogenic characteristics, and control strategies for Korean H9N2 AI. This review may provide some clues for establishing control strategies for endemic AIV and a newly introduced Y280 lineage of H9N2 AI in South Korea.

Background/Aims: The purpose of this study was to investigate the risk factors and long-term clinical outcomes of non-curative resection (NCR) in a large-scale patient population. Methods: We retrospectively analyzed the clinical data of 3,094 patients who underwent endoscopic submucosal dissection (ESD) of early gastric cancer from March 2005 to March 2018 at 13 institutions in Korea. We analyzed the risk factors for NCR and the survival between patients with curative resection and those with NCR with no additional treatment. Results: The NCR rate was 21.4% (661/3,094). In multivariate regression analysis, the risk factors affecting NCR with ESD were old age, undifferentiated tumor, tumor location in the upper body, tumor size ≥2 cm, and presence of an ulcer. In Cox proportional hazard regression analysis, tumor size ≥2 cm, submucosal invasion, positive horizontal margin, and lymphovascular invasion were risk factors for local recurrence. In Kaplan-Meier analysis, there was no statistically significant difference in the overall survival between the two groups (log-rank p=0.788). However, disease-specific survival was significantly lower in the NCR group (log-rank p=0.038). Conclusions Clinicians should be aware of the risk factors for NCR and local recurrence after ESD for early gastric cancer, and should consider providing additional treatment after NCR.

From May 1995 to February 1997, 46 patients underwent resectoscopic surgery for infertility. Of 46 patients, 32 patients had uterine synechiae, 5 patients had polyps, 3 patients had septums, 3 patients had bony foreign bodies, 2 patients had submucosal myomas, 1 patient had tuberculous endometritis. The resectoscopic procedure proved of special value for resection of intrauterine adhesion, submucosal myoma, septum and polyp. Except 5 patients, intrauterine conditions were improved and 10 patients were conceived. So it goes without saying that resectoscopic surgery is a effective and acceptable procedure for the management of infertility of endometrial factors. However, with the finding of slightly less satisfactory results with time and number, further follow-up is still needed to establish the usefulness of the procedure.

Duodenal diverticulitis is a rare cause of upper abdominal pain and is usually not considered when evaluating patients with acute upper abdominal pain. Furthermore, the duodenum is located near the pancreas and bile duct, and duodenal diverticulitis can be misdiagnosed as acute pancreatitis, cholangitis, cholecystitis, or other pancreatobiliary disorders such as pancreatic cystic neoplasms. Recently, we experienced a rare case of duodenal diverticulitis in the 3rd portion of the duodenum. The patient presented with deep seated upper abdominal pain aggravated by supine posture and relieved by sitting up. The patient was initially diagnosed with acute pancreatitis. However, serum levels of pancreatic enzymes were normal and abdominal CT scan revealed diverticulitis in the 3rd portion of the duodenum. The patient was successfully managed conservatively. Delayed diagnosis of duodenal diverticulitis can result in substantial morbidity and mortality if duodenal perforation occurs and should be considered as a possible cause of upper abdominal pain.

Renal infarction in transplant kidney is an very uncommon post-transplant complication, and usually occurs in the early postoperative period. Thromboemboli to the renal arteries usually originate from the heart, e.g. atrial fibrillation. This paper reports a 64-year-old man who had total occlusion of transplanted renal artery after 9 years from transplantation. His medicines included cyclosporine, prednisolone, aspirin, clopidogrel, and propranlol. Our patient presented with fever, oliguria, and left costovertebral angle tenderness, three days ago. Abdominal computed tomography (CT) revealed total occlusion of transplanted renal artery and right common iliac artery. Preservation of renal function is inversely proportional to the period of renal ischemia. Our patient was treated with heparinization. Remnant renal function was lost, he has been treated with hemodialysis.
