COVID-19 infection manifesting as a severe gastroparesis flare: A case report.

Rationale: Coronavirus disease 2019 (COVID-19) is a disease caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which commonly presents with symptoms including fever, cough, and dyspnea. More recently, however, some patients have tested positive for COVID-19 after developing gastrointestinal (GI) symptoms either solely or in conjunction with respiratory symptoms. This may be due to SARS-CoV-2 infection of the GI tract.

Vascular pressure bands on high-resolution esophageal manometry with impedance studies.

Horizontal pressure bands on high-resolution esophageal manometry with impedance (HREMI) tracings are often seen and thought to be due to cardiovascular structures compressing the esophagus. The aim of this study was to determine the prevalence and location of vascular pressure bands on HREMI studies and correlate these pressure bands to bolus clearance. HREMI studies in supine and upright positions from patients and normal volunteers were reviewed.

Multiple Rapid Swallows (MRS) Complements Single-Swallow (SS) Analysis for High-Resolution Esophageal Manometry (HREM).

Background: Multiple rapid swallows (MRS) during HREM assess post-deglutitive inhibition, LES relaxation, and subsequent esophageal contraction.

Aims: (1) To determine the relationship between MRS and single-swallow (SS) responses and (2) to determine if MRS provides information for symptomatic patients.

Methods: Healthy volunteers (HVs) and patients underwent HREM [30-s landmark, ten 5-mL SS, MRS (5 consecutive 2-mL swallows every 2-3 s)] and were analyzed with ManoView software version 3 with CC version 3.

Effect of Chronic Domperidone Use on QT Interval: A Large Single Center Study.

Goals: The goal of this study was to determine the effect and safety of domperidone on QTc interval at the commonly prescribed doses of 30 to 80 mg daily.

Background: Domperidone is a dopamine receptor antagonist used for the treatment of gastroparesis. However, it has been associated with QT prolongation, ventricular arrhythmias, and sudden cardiac death.

Mucosa-Associated Lymphoid Tissue Lymphoma of the Sigmoid Colon Discovered on Routine Screening Colonoscopy in Patient with Hepatitis C and Infection.

Mucosa-associated lymphoid tissue (MALT) lymphoma is predominantly found in the stomach. Rarely, it is found in the proximal colon and even less so in the sigmoid colon. We present a rare case of primary sigmoid colon MALT lymphoma in a patient with concomitant and hepatitis C infection.
