A Case of Pancreatic Serous Cystadenoma Penetrating Bile Duct Requiring Differentiation from Malignancy.

A 67-year-old man was admitted to our hospital with jaundice. A closer examination revealed that he had obstructive jaundice due to bile duct obstruction caused by a multifocal cystic tumor of the pancreas. Endoscopic retrograde cholangiopancreatography (ERCP) revealed stenosis of the distal bile duct and leakage of contrast medium into the pancreatic cyst.

Ectopic Adrenocorticotropic Hormone Syndrome due to Pancreatic Neuroendocrine Carcinoma.

A 55-year-old woman presented to her primary care physician with facial and lower leg edema. After being referred to our hospital because of hypothyroidism and hypokalemia on blood tests, she also had elevated adrenocorticotropic hormone (ACTH) and cortisol levels, but a dexamethasone suppression test showed no cortisol suppression. Ectopic ACTH syndrome due to pancreatic neuroendocrine carcinoma (PNEC) was suspected.

Isolation of Pro-Osteogenic Compounds from That Reciprocally Regulate Osteoblast and Osteoclast Differentiation.

Plants contain a large number of small-molecule compounds that are useful for targeting human health and in drug discovery. Healthy bone metabolism depends on the balance between bone-forming osteoblast activity and bone-resorbing osteoclast activity. In an ongoing study searching for 22 plant extracts effective against osteoporosis, we found that the crude extract of Sieb.
