Young Kwang Shim, Nayoung Kim
The first histamine H2 receptor antagonists (H2RAs) were developed in the early 1970s. They played a dominant role in treating peptic ulcer disease and gastroesophageal reflux disease (GERD). H2RAs block the production of acid by H(+), K(+)-ATPase at the parietal cells and produce gastric luminal anacidity for varying periods. H2RAs are highly selective, and they do not affect H1 receptors. Moreover, they are not anticholinergic agents. Sequential development of H2RAs, proton pump inhibitors (PPIs), and discovery of Helicobacter pylori infection changed the paradigm of peptic ulcer disease with marked decrease of morbidity and mortality...

Type 2 diabetes (T2D) is a progressive disease affecting glucose regulation and a major cause of morbidity and mortality globally. Many patients are not escalated up the treatment ladder appropriately despite failing to achieve glycemic control, with barriers such as fear of hypoglycemia, weight gain, and treatment burden recognized as factors. Exogenous basal insulin is titrated to address control of fasting plasma glucose and may preserve residual β-cell function, thus promoting a greater endogenous prandial insulin response...

We examined a methylcellulose (MC) formulation that gels at body temperature for enteral alimentation. Betaine was found to have a lowering effect on the gelation temperature of the MC solution. The thermal gelation temperature of a body heat-responsive (BHR) gelling MC formulation, consisting of 2% MC, 15% glucose, 1.2% sodium citrate, and 3.5% betaine mixture, was approximately 32 °C, indicating that it could gel in response to body heat. Glucose release from the BHR gels was delayed at 37 °C in an in vitro study...

OBJECTIVES: Previous research on gastrointestinal and other medical conditions has shown the presence of incongruence between self- and clinician-reported functioning and its relation with psychopathology. The main objective of this study was to test whether inconsistencies between clinician- and self-assessed functionality can be used to detect psychopathology among patients diagnosed of motor or functional gastrointestinal disorders. METHODS: One hundred and three patients from a gastroenterology inpatient unit were included in this study...

BACKGROUND: Gastric motility is a key-factor in the pathogenesis of functional dyspepsia (FD). 13C-octanoic acid breath test (OBT) is a tool used for measuring gastric emptying time in clinicalsetting. We aimed to investigate the variation in FD symptoms and OBT parameters after treatment with buspirone, amitriptyline or clebopride. METHODS: Between Jan-2007 and Dec-2014, we enrolled 59 patients with FD unresponsive to firstling therapy with proton pump inhibitors and/or domperidone that underwent OBT before and after 3 months of buspirone (n=32), amitriptyline (n=16) or clebopride (n=11) treatment...

Chronic constipation and gastrointestinal motility disorders constitute a large part of a gastroenterology practice and represent a significant impact on patient quality of life and lifestyle. In most cases, medications are prescribed to alleviate symptoms without an objective measurement of response. Commonly used current investigations of gastrointestinal transit times are limited to radiopaque markers or electronic capsules. Repeated use of these techniques is limited due to radiation exposure or the significant cost of the devices...

Suicidal intoxication from massive propranolol ingestion is rare. Surprisingly, no reported cases have involved physicians. The author herein reports a case of self-poisoning death due to ingestion of propranolol by a young male physician. A 31-year-old man with major depressive disorder was found dead in his dormitory room. Fifteen empty packages, each having contained ten 40-mg propranolol tablets, were found without any tablets leftover in his room. A suicide note was also found in his room. He was thus alleged to have ingested 6 g of propranolol for self-poisoning...

Traditional autopsy has changed little in the past century. In Japan, the rate of forensic autopsy in cases of unusual death is very low. Therefore, multi-slice computed tomography (CT) has been used to obtain imaging data instead of or in addition to autopsy in suspicious forensic cases. In our institute, postmortem multi-slice CT has been performed since 2009, and by 2014 there were over 1,000 cases. Our extensive experience with postmortem CT shows that in many cases of death by drug overdose, stomach contents exhibit high X-ray absorption...

BACKGROUND: Gastroparesis is a common complication after splenectomy and azygoportal disconnection, remaining a chronic debilitating disorder with considerable treatment challenges. To minimize postoperative gastroparesis, we have developed a new modified laparoscopic pyloroplasty (LP) technique for use during laparoscopic splenectomy and azygoportal disconnection (LSD). METHODS: We retrospectively evaluated the outcomes of 31 cirrhotic patients with portal hypertensive bleeding and secondary hypersplenism who underwent synchronous LSD with modified LP (n = 14) or LSD without modified LP (n = 17) between January 2015 and August 2015...

INTRODUCTION: Delayed gastric emptying (DGE) is a common serious problem after pancreatoduodenectomy (PD). Flange gastrojejunostomy (FL-GE) is a previously described technique that creates an internal flange in a hand sewn gastroenterostomy. Results of FL-GE on incidence and severity of DGE after PD are presented. METHODS: Data were extracted from a prospective database of PD. Standard PD with antrectomy were performed -with Flange Gastroenterostomy (FL-GE) or other techniques (NonFL-GE) at a single institution...

Obesity prevalence has been increasing with devastating health and economic consequences. Botulinum toxin type A (BTX-A), a neurotoxin, is used clinically for conditions characterized by prolonged muscular contraction. Its inhibitory effects on gastric smooth muscles, in theory, make it a potential agent for obesity treatment through delayed gastric emptying and increased satiety. This review aims to examine the evidence for the use of endoscopic BTX-A injection for treating obesity. The literature search identified 60 articles with 11 primary studies as relevant for the scope of the review...

BACKGROUND: When performing dynamic gastric emptying scintigraphy with continuous acquisition in children, a single posterior view acquisition is preferred because it allows the young patient to more easily interact with a parent or technologist even though this method tends toward overestimating gastric emptying. OBJECTIVES: The objective of our study was to develop a new attenuation correction (AC) method to improve the accuracy of the time activity curve and the measurement of residual gastric emptying from 1-h posterior images of gastric emptying scintigraphy with continuous acquisition...

The gastrointestinal (GI) tract has a central role in nutritional homeostasis, as location for food ingestion, digestion and absorption, with the gut endocrine system responding to and regulating these events, as well as influencing appetite. One key GI hormone with the full spectrum of these activities is cholecystokinin (CCK), a peptide released from neuroendocrine I cells scattered through the proximal intestine in response to fat and protein, with effects to stimulate gall bladder contraction and pancreatic exocrine secretion, to regulate gastric emptying and intestinal transit, and to induce satiety...

Postprandial hypotension (PPH) occurs frequently and is thought to reflect an inadequate increase in cardiac output to compensate for the rise in splanchnic blood flow after a meal. Gastric distension by water attenuates the postprandial fall in blood pressure (BP). Cardiac hemodynamics (stroke volume (SV), cardiac output (CO), and global longitudinal strain (GLS)) have hitherto not been measured in PPH We sought to determine the comparative effects of water and glucose drinks on cardiac hemodynamics in healthy older subjects and individuals with PPH Eight healthy older subjects (age 71...

Inflammation plays a role in abdominal surgery (AS)-induced intestinal ileus that is alleviated by electrical vagal stimulation. The stable thyrotropin-releasing hormone agonist, RX77368 injected intracisternally (ic) activates dorsal motor nucleus neurons and gastric vagal efferent discharges. We investigated the gastric inflammation induced by AS and the modulation by ic RX-77368 in rats. RX77368 (50 ng/rat) or saline was injected ic followed, 1 h later, by laparotomy and small intestinal/cecal manipulation...
