The aim of this study was to determine the potential associations between perinatal risk factors and EoE. A search was conducted for relevant studies published up to December 12th, 2023, using MEDLINE, EMBASE, Scopus, Web of Sciences, and Cochrane databases.

Esophageal Radiography Interpretation: a Primer for the Gastroenterologist.

Purpose Of Review: Radiological studies can be helpful when evaluating patients with suspect esophageal disorders. From benign strictures to malignancy and motility disorders such as achalasia, imaging modalities play a significant role in diagnosis. This review explores the role of different imaging modalities in the most frequently encountered esophageal pathologies.

Esophageal Lichen Planus: A Descriptive Multicenter Report.

Goals: To better understand the characteristics, treatment approaches, and outcomes of patients with esophageal lichen planus (ELP).

Background: ELP is a rare, often unrecognized and misdiagnosed disorder. Data on this unique patient population are currently limited to small, single-center series.

Physiological and morphological responses of seedlings to moisture limitations in the nursery and their implications for restoration.

Successful establishment of seedlings in the southwestern United States is often limited by stressful and harsh site conditions related to drought severity and severe disturbances such as wildfire and mining operations. Seedling quality has an important influence on outplanting performance, but nursery practices that typically employ optimal growing environments may also be limiting seedling morphological and physiological performance on stressful outplanting sites. To address this, a study was established to test alterations in seedling characteristics subjected to irrigation limitations during nursery culture and their subsequent outplanting performance.

Role of functional luminal imaging probe in the management of postmyotomy clinical failure.

Background And Aims: A small percentage of patients with esophageal dysmotility disorders (EDDs) fail to improve or relapse after management by laparoscopic Heller myotomy (LHM) and peroral endoscopic myotomy (POEM). In this study, we aimed to describe the role of functional luminal imaging probe (FLIP) in identifying patients who might benefit from lower esophageal sphincter (LES)-directed retreatment.

Methods: This was a retrospective study at 6 tertiary care centers (United States, 4; Europe, 1; Asia, 1) between January 2015 and April 2021 involving patients with prior failed myotomy.

Drought-Conditioning of Quaking Aspen ( Michx.) Seedlings During Nursery Production Modifies Seedling Anatomy and Physiology.

In the western US, quaking aspen ( Michx.) regenerates primarily by root suckers after disturbances such as low to moderate severity fires. Planting aspen seedlings grown from seed may provide a mechanism to improve restoration success and genetic diversity on severely disturbed sites.

Gastrointestinal pharmacology: practical tips for the esophagologist.

Gastroesophageal reflux disease (GERD) is primarily a motor disorder, and its pathogenesis is multifactorial. As a consequence, treatment should be able to address the underlying pathophysiology. Proton pump inhibitors (PPIs) are the mainstay of medical therapy for GERD, but these drugs only provide the control of symptoms and lesions without curing the disease.

Impedance in the evaluation of the esophagus.

The aim of this paper is to review esophageal electrical impedance technologies and to discuss the use of these technologies for physiological measurements, diagnostics, and therapy of esophageal disease. In order to develop a better understanding of the pathophysiology of and improve the diagnosis of esophageal disorders, such as gastroesophageal reflux disease (GERD) and achalasia, several new diagnostic tests, including intraluminal impedance, esophageal mucosal impedance, and the functional luminal imaging probe, have been developed. These technologies have proven valuable for assessment of the esophagus in recent years.

Esophageal Manometry Competency Program Improves Gastroenterology Fellow Performance in Motility Interpretation.

Introduction: Competency-based medical education (CBME) for interpretation of esophageal manometry is lacking; therefore, motility experts and instructional designers developed the esophageal manometry competency (EMC) program: a personalized, adaptive learning program for interpretation of esophageal manometry. The aim of this study was to implement EMC among Gastroenterology (GI) trainees and assess the impact of EMC on competency in manometry interpretation.

Methods: GI fellows across 14 fellowship programs were invited to complete EMC from February 2018 to October 2018.

Treatment experience with a novel 30-mm hydrostatic balloon in esophageal dysmotility: a multicenter retrospective analysis.

Background And Aims: The newest addition in the management of achalasia and esophagogastric junction outflow obstruction (EGJOO) is a 30-mm hydrostatic balloon dilator that uses impedance planimetry technology. It allows for the measurement of the diameter and cross-sectional area to determine effective dilation. We aimed to (1) determine the clinical success (defined as a decrease in Eckardt score to ≤3) in the treatment of esophageal motility disorders and (2) report the safety (rate/severity of adverse events).

Jackhammer Esophagus: Symptom Presentation, Associated Distal Contractile Integral, and Assessment of Bolus Transit.

Goals: The aim of our study was to characterize jackhammer esophagus symptoms and their relationship with the distal contractile integral (DCI) and bolus transit.

Background: Jackhammer esophagus is defined by the Chicago Classification version 3.0.

Proton Pump Inhibitor-Induced Remission of Lymphocytic Esophagitis.

Lymphocytic esophagitis is a chronic condition that has been described in the literature; however, there is little information describing its characteristics and treatment. We present a case of lymphocytic esophagitis that was identified following food impaction. Repeat esophagogastroduodenoscopy (EGD) with biopsy showed a marked decrease in lymphocytic infiltration after a 6-week course of twice-daily high-dose proton pump inhibitor (PPI).

Use of Aldosterone Antagonist to Treat Diarrhea and Hypokalemia of Ogilvie's Syndrome.

Ogilvie's syndrome (OS) is a functional obstruction of the bowel due to an autonomic imbalance. It often presents with diarrhea and is associated with hypokalemia. We present a case of a 70-year-old male who developed severe abdominal distension, watery diarrhea, and persistent hypokalemia status after left hip arthroplasty after suffering from a femoral neck fracture due to a fall and was diagnosed with OS.

Reduced translocation of current photosynthate precedes changes in gas exchange for Quercus rubra seedlings under flooding stress.

Northern red oak (Quercus rubra L.) seedlings are frequently planted on suboptimal sites in their native range in North America, subjecting them to environmental stresses, such as flooding, for which they may not be well adapted. Members of the genus Quercus exhibit a wide range of responses to flooding, and responses of northern red oak to flooding remain inadequately described.

A 4-week pilot study with the cannabinoid receptor agonist dronabinol and its effect on metabolic parameters in a randomized trial.

Purpose: Dronabinol (synthetic Δ(9)- tetrahydrocannabinol) is used in patients with nausea and vomiting from chemotherapy and in AIDS patients for appetite stimulation. Recently, dronabinol was used to successfully treat visceral hypersensitivity causing noncardiac chest pain. With widening uses of this medication, we aim to explore its effects on metabolic parameters in long-term dosing and hypothesize that it will not affect major metabolic parameters.

Dosing Cefepime for Renal Function Does Not Completely Prevent Neurotoxicity in a Patient With Kidney Transplant.

Dosing cefepime for renal function does not completely prevent neurotoxicity in a kidney transplant patient. Cefepime neurotoxicity has been reported primarily among patients with renal insufficiency who received standard doses of the antibiotic. We report a case of nonconvulsive status epilepticus from dose-adjusted cefepime in a kidney transplant patient.

Carbon translocation patterns associated with new root proliferation during episodic growth of transplanted Quercus rubra seedlings.

Patterns of carbon allocation in northern red oak (Quercus rubra L.), characterized by episodic growth through recurrent single-season flushing, vary by growth stage. To examine post-transplant timing and carbohydrate sources for new root growth, dormant, bare-root, half-sibling northern red oak seedlings were transplanted to pots and placed in a favorable growth chamber environment.
