Incisional bladder hernia following appendectomy: report of a case.

We herein report the case of a 68-year-old male who presented with a few years' history of swelling at the scar of an appendectomy, which he had undergone nearly 40 years earlier, and which was associated with radiating pain towards the penis when he pushed on the swelling. The scar was located in the right lower quadrant of the abdomen. Abdominal sonography and a computed tomography (CT) scan demonstrated the presence of an incisional bladder hernia, and surgery was performed. The herniated bladder was successfully replaced into the preperitoneal space, and the orifice was covered with a polypropylene mesh. Most bladder hernias develop in the inguinal and/or femoral region, and an incisional bladder hernia is extremely rare, especially after abdominal surgery. To our knowledge, this is the fourth report of an incisional bladder hernia following abdominal surgery.

[A case of long-term survival after resection of metastatic lymph nodes along the superior mesenteric vein from early gastric cancer].

A 63-year-old man underwent distal gastrectomy and D1 + beta lymph node dissection for type II c early gastric cancer in the posterior wall of the antrum. In the fifth postoperative month, a mass appeared in the epigastric region, and serum tumor marker levels rose. Abdominal CT revealed a 4-cm mass anterior to the superior mesenteric vein. He was diagnosed with recurrence in the lymph nodes along the superior mesenteric vein (No. 14v). Since there was no evidence of recurrence elsewhere, the patient underwent resection of the lymph nodes and transverse colectomy, followed by five courses of chemotherapy with S-1 + cisplatin. At present, more than 38 months after surgery, he is alive without recurrence. Generally, chemotherapy is the first-line treatment for recurrent gastric cancer; however, surgery appears to be a treatment option if the tumor is localized and resectable.

Novel DNA virus isolated from samples showing endothelial cell necrosis in the Japanese eel, Anguilla japonica.

Economic loss due to viral endothelial cell necrosis of eel (VECNE) of Anguilla japonica is a serious problem for the cultured Japanese eel market. However, the viral genome responsible for VECNE is unknown. We recently developed a rapid determination system for viral nucleic acid sequences (RDV) to determine viral genome sequences. In this study, viral DNA fragments were obtained using RDV, and approximately 15-kbp circular full genome sequences were determined using a next-generation sequencing system, overlapping PCR, and Southern blot analysis. One open reading frame (ORF) was homologous to the large T-antigen of polyomavirus; other ORFs have no homology with any nucleic or amino acid sequences of polyomavirus. Therefore, as this DNA virus might comprise a novel virus family, we provisionally named it Japanese eel endothelial cells-infecting virus (JEECV). JEECV was detected in both naturally and experimentally infected eels, suggesting that JEECV potentially causes VECNE.
