The growing epidemic of obesity has led health professionals to understand the pathophysiology of obesity and its complications. Gut microbiota are of special interest, since some kinds of microbiota such as Bacteroides are less in obese persons and some microbiota induce obesity in animals by effective fat storage through microbiota-mediated intestinal Fiaf (Fasting-induced adipose factor) suppressions. Recently, bile acid-binding resins (BARs), non-absorbable drug for dyslip...

Introduction: Surgical treatment of giant GH cell adenomas (>4 cm in maximum diameter; GHomas) has been considered difficult. However, clinical and histological characteristics of these adenomas are still enigmatic. We retrospectively analyzed data of 17 giant GHomas experienced at Toranomon hospital to clarify their characteristics.Methods: These 17 patients, accounting for 3.1% of 549 acromegalic patients undergoing surgery between 2006 and 2011, w...

Background and aims: Excess GH causes insulin resistance resulting in impaired glucose metabolism. Although diabetes mellitus (DM) is common in patients with acromegaly, diabetic ketoacidosis (DKA) is rarely associated with acromegaly. Actually only 11 DKA patients have been anecdotally reported as the first presentation of acromegaly so far. Here we present nine cases of DKA as the first presentation of 860 consecutive patients with acromegaly and their clinical characteristi...

More than half of patients with multiple endocrine neoplasia type 1 (MEN1) develop gastroenteropancreatic neuroendocrine tumors (GEPNETs). Among GEPNETs in MEN1, insulinoma is the second common functioning tumor and often diagnosed by its pathognomonic clinical feature, i.e. hypoglycemia. Compared to other functioning and nonfunctioning GEPNETs in MEN1, insulinoma is known to develop in younger age. We have recently constructed a database of Japanese patients with MEN1 and her...
