Adrenocortical oncocytic tumors are rare. As the Weiss criteria overestimate the malignancy of oncocytic tumor due to histological hallmarks, the Lin-Weiss-Bisceglia system (LWB system) is required for an accurate diagnosis of the malignant potential of an oncocytic tumor. We report two cases diagnosed as an oncocytic tumor with uncertain malignant potential (borderline) and an oncocytic tumor (benign) based on the LWB system, both of which were diagnosed as malignant based on the Weiss criteria. Case 1 : A man in his 20s was referred to our hospital for treatment of a left adrenal tumor. A non-functional pheochromocytoma or adrenal cancer was suspected. He underwent surgical resection of the left adrenal tumor and left kidney. The specimen was positive for 3 of the 9 Weiss criteria, but met one minor criterion in the LWB system. He was diagnosed with an oncocytic tumor with uncertain malignant potential (borderline). Case 2 : A woman in her 40s was referred to our hospital for treatment of a left adrenal tumor. Under the possibility of adrenal cancer, she underwent surgical resection of the left adrenal tumor. The specimen was positive for 3 of the 9 Weiss criteria, but the specimen met no criteria in the LWB system. She was diagnosed with an oncocytic tumor (benign). There has been no recurrence of the oncocytic tumor as of 2 years of follow-up in the two patients.

A 17-year-old man received continuous ambulatory peritoneal dialysis (CAPD) catheter implantation and had started peritoneal dialysis. Perfusion failure of peritoneal dialysis catheter occurred one month after the catheter implantation. Transcatheter contrast examination revealed catheter obstruction about 4-5 cm from the catheter tip. We performed reduced port surgery to remove the obstruction. Laparoscopy revealed that the omentum was adhered to the abdominal wall and wrapped the catheter. We diagnosed the cause of catheter malfunction as omentum wrapping. We removed the omentum from the catheter, and repositioned the catheter into the Douglas fossa. Although CAPD worked successfully after the operation, perfusion failure recurred one month after the operation. The patient requested discontinuation of CAPD and change to hemodialysis. Therefore, we removed the CAPD catheter. The catheter was adhered to the omentum. Reduced port surgery for peritoneal dialysis catheter obstruction has the advantage of being minimally invasive and is a reliable procedure, but further studies are needed to reduce the recurrence rate of perfusion failure and to establish the procedure after perfusion failure.

A 32-year-old woman was referred to our hospital for consultation with a suspected left adrenal tumor detected by ultrasonography at a health check. Computed tomography and magnetic resonance imaging revealed a 3×1×4 cm multilocular cystic mass arising from the diaphragmatic crura, suggesting a retroperitoneal bronchogenic cyst. The patient underwent excision of the cyst and adjacent diaphragm using a retroperitoneoscopic approach. Retroperitoneal bronchogenic cysts are rare. We review the cases of 26 patients who underwent laparoscopic resection of a retroperitoneal bronchogenic cyst.

We considered developing new confectionery utilizing Imo-fry which is the local food of Sano City as a motif. Research was focused on puffed snack which uses extruder. We studied structural observation and physical properties evaluation about influences to add potatoes as ingredients of snack. It was meaningful research to explore issues for realizing confectionery development, including noticing the need to evaluate taste and texture.

"Tochiotome" and "Skyberry" that are out of the standard are discarded. We aimed at these being used. In this paper, We studied an optimal method to make "Tochiotome" and "Skyberry" powder. Furthermore, We examined the way that the color of strawberry and anthocyanins are keeped. The results obtained were as follows: First, among the heat drying methods, the most suitable conditions were 50℃ , 48 hours, and the thickness was 3 ㎜ . Strawberry turned brown when heated at 60℃ and 70℃. Powder at 50℃ was better than powder at 40℃ with color and the amount of anthocyanin. Second, the freeze drying was better than the heat drying at 50 ℃ with color and particle fineness. However, the amount of anthocyanin of powder at 50℃ was higher.

Study on original dessert recipe suggestion. 66 recipes were submitted from students. The 14 recipes were chosen by competition. And, the 14 recipes were developed. We chose 3 recipes from them, and we decided to serve them for tasting at the Michinoeki. We collected the response from people who ate those desserts. It was a good opportunity for us to know favors of customers.
