PECNet: A Deep Multi-Label Segmentation Network for Eosinophilic Esophagitis Biopsy Diagnostics [PDF]
arXiv, 2021 Background. Eosinophilic esophagitis (EoE) is an allergic inflammatory condition of the esophagus associated with elevated numbers of eosinophils. Disease diagnosis and monitoring requires determining the concentration of eosinophils in esophageal biopsies, a time-consuming, tedious and somewhat subjective task currently performed by pathologists ...

A manometric feature descriptor with linear-SVM to distinguish esophageal contraction vigor [PDF]
arXiv, 2023 n clinical, if a patient presents with nonmechanical obstructive dysphagia, esophageal chest pain, and gastro esophageal reflux symptoms, the physician will usually assess the esophageal dynamic function. High-resolution manometry (HRM) is a clinically commonly used technique for detection of esophageal dynamic function comprehensively and objectively.

Ambulatory Esophageal pH Monitoring: New Directions [PDF]
Digestive Diseases, 2006 pH testing remains a commonly used evaluative tool in clinical practice. However, the original tool that included a nasally placed pH catheter was plagued with a variety of shortcomings, primarily the effect of the procedure on patients’ lifestyle and thus on reflux-provoking activities.

Characterizing reflux on high resolution esophageal manometry with impedance
BMC Gastroenterology, 2022 Background In some patients, reflux at esophagogastric junction (EGJ) can be seen on the impedance portion of the high-resolution esophageal manometry with impedance (HREMI) studies.

Esophageal pH and Combined Impedance-pH Monitoring in Children [PDF]
Pediatric Gastroenterology, Hepatology & Nutrition, 2014 Esophageal pH monitoring is considered the gold standard for the diagnosis of gastroesophageal reflux disease because of the normal ranges across the pediatric age range. However, this method can only detect acid reflux. Multichannel intraluminal impedance-pH (MII-pH) monitoring has recently been used for the detection of bolus reflux in infants and ...

Deep-learning models in medical image analysis: Detection of esophagitis from the Kvasir Dataset [PDF]
arXiv, 2023 Early detection of esophagitis is important because this condition can progress to cancer if left untreated. However, the accuracies of different deep learning models in detecting esophagitis have yet to be compared. Thus, this study aimed to compare the accuracies of convolutional neural network models (GoogLeNet, ResNet-50, MobileNet V2, and ...

Probing the pH microenvironment of mesenchymal stromal cell cultures on additive-manufactured scaffolds [PDF]
, 2021 Despite numerous advances in the field of tissue engineering and regenerative medicine, monitoring the formation of tissue regeneration and its metabolic variations during culture is still a challenge and mostly limited to bulk volumetric assays. Here, a simple method of adding capsules based optical sensors in cell seeded 3D scaffolds is presented and
