Effects of Diaphragmatic Breathing on the Pathophysiology and Treatment of Upright Gastroesophageal Reflux: A Randomized Controlled Trial.

Magnus Halland, Adil E Bharucha, Michael D Crowell, Karthik Ravi, David A Katzka,

<h4>Introduction</h4>Uncontrolled results suggest that diaphragmatic breathing (DB) is effective in gastroesophageal reflux disease (GERD) but the mechanism of action and rigor of proof is lacking. This study aimed to determine the effects of DB on reflux, lower esophageal sphincter (LES), and gastric pressures in patients with upright GERD and controls.<h4>Methods</h4>Adult ... Read more >>

Esophageal Motility Disorders.

John M Wilkinson, Magnus Halland,

Esophageal motility disorders can cause chest pain, heartburn, or dysphagia. They are diagnosed based on specific patterns seen on esophageal manometry, ranging from the complete absence of contractility in patients with achalasia to unusually forceful or disordered contractions in those with hypercontractile motility disorders. Achalasia has objective diagnostic criteria, and ... Read more >>

Baseline Impedance Measured During High-resolution Esophageal Impedance Manometry in Patients With Rumination Syndrome is as Abnormal as in Patients With GERD.

Magnus Halland, Karthik Ravi, Holly A Nelson, David A Katzka, Nicholas J Talley, Michael D Crowell,

<h4>Goals and background</h4>Baseline impedance measured during high-resolution impedance manometry (HRIM) can distinguish patients with gastroesophageal reflux disease (GERD) from controls, presumably due to differences in esophageal acid exposure. The characteristics of regurgitation and reflux in rumination syndrome and GERD are very different, and thus we investigated whether baseline esophageal impedance ... Read more >>

Management of Diarrhea in Patients With Carcinoid Syndrome.

Boris G Naraev, Magnus Halland, Daniel M Halperin, Amy J Purvis, Thomas M OʼDorisio, Thorvardur R Halfdanarson,

Neuroendocrine tumors (NETs) arise from enterochromaffin cells found in neuroendocrine tissues, with most occurring in the gastrointestinal tract. The global incidence of NETs has increased in the past 15 years, likely due to better diagnostic methods. Small-bowel NETs are frequently associated with carcinoid syndrome (CS). Carcinoid syndrome diarrhea occurs in ... Read more >>

Subhankar Chakraborty, Magnus Halland, Duane Burton, Anshuman Desai, Bridget Neja, Phillip Low, Wolfgang Singer, Michael Camilleri, Alan R Zinsmeister, Adil E Bharucha,

<h4>Context</h4>Delayed gastric emptying (GE) is common but often asymptomatic in diabetes. The relationship between symptoms, glycemia, and neurohormonal functions, including glucagonlike peptide 1 (GLP-1), are unclear.<h4>Objectives</h4>To assess whether GE disturbances, symptoms during a GE study, and symptoms during enteral lipid infusion explain daily symptoms and whether GLP-1 mediates symptoms during ...

Subhankar Chakraborty, Anshuman Desai, Magnus Halland, Duane Burton, Michael Camilleri, Alan R Zinsmeister, Adil E Bharucha,

<h4>Background</h4>Non-ulcer dyspepsia (NUD) is a heterogeneous disorder, which is characterized by upper gastrointestinal symptoms and sensorimotor disturbances, including abnormal gastric emptying (GE) and increased intestinal chemosensitivity, and associated with greater plasma glucagon-like peptide-1 (GLP-1) levels during duodenal lipid infusion. However, the relationship(s) between these disturbances and daily symptoms in NUD ... Read more >>

Duodenal Pathology in Patients with Rumination Syndrome: Duodenal Eosinophilia and Increased Intraepithelial Lymphocytes.

Magnus Halland, Nicholas J Talley, Mike Jones, Joseph A Murray, Raquel Cameron, Marjorie M Walker,

<h4>Background</h4>Rumination syndrome is a functional gastrointestinal disorder characterized by effortless, postprandial regurgitation. Duodenal eosinophilia has been described in patients with functional dyspepsia. Because of the significant symptomatic overlap between functional dyspepsia and rumination syndrome, we hypothesized that histological changes might exist among patients with rumination syndrome.<h4>Methods</h4>We included patients with rumination ...

Diagnosis and Treatment of Rumination Syndrome.

Magnus Halland, John Pandolfino, Elizabeth Barba,

Rumination syndrome is a functional gastrointestinal disorder characterized by effortless postprandial regurgitation. The disorder appears uncommon, although only limited epidemiologic data are available. Awareness of the characteristic symptoms is essential for recognizing the disorder, and thus avoiding the long delay in diagnosis, that many patients experience. Although objective testing by ...

Diagnosis of Esophageal Motility Disorders: Esophageal Pressure Topography vs. Conventional Line Tracing.

Dustin A Carlson, Karthik Ravi, Peter J Kahrilas, C Prakash Gyawali, Arjan J Bredenoord, Donald O Castell, Stuart J Spechler, Magnus Halland, Navya Kanuri, David A Katzka, Cadman L Leggett, Sabine Roman, Jose B Saenz, Gregory S Sayuk, Alan C Wong, Rena Yadlapati, Jody D Ciolino, Mark R Fox, John E Pandolfino,

<h4>Objectives</h4>Enhanced characterization of esophageal peristaltic and sphincter function provided by esophageal pressure topography (EPT) offers a potential diagnostic advantage over conventional line tracings (CLT).
