A Novel Approach to Repair of Tracheal Occlusion Secondary to Percutaneous Tracheostomy Creation.

The number of endotracheal intubations increased in the United States during the COVID-19 pandemic with an associated rise in laryngotracheal injury. Our patient had a complete laryngeal occlusion just proximal to the first tracheal ring. The Neodymium-doped Yttrium Aluminum Garnet (Nd-YAG) laser is often used to resolve sub-laryngeal occlusions, and without access to the Nd-YAG laser, we had to find an alternative solution.

A 76-day-old Japanese Black calf presented with severe stridor, resenting palpation of the laryngeal region. Endoscopic examination revealed an expansile process restricting the esophageal and tracheal lumina caudal to the arytenoid cartilage, hyperemia and edema of the pharyngeal mucosa, right arytenoid cartilage swelling and displacement, and marked airway obstruction. The absence of an endotracheal wall abnormality impeded a definitive diagnosis.

Background & Aims: The region of the esophagus 15-17 cm below the incisors, called the sub-upper esophageal sphincter (sub-UES), has not been characterized in adults with eosinophilic esophagitis (EoE) but appears different during endoscopy. We investigated how the sub-UES differs from the remaining esophagus in patients with EoE and aimed to determine whether these differences be used to distinguish patients with EoE from those with lichen planus.
Methods: We performed a prospective study of 14 patients with EoE, 7 patients with lichen planus (based on presence of Civatte bodies, dysphagia, and/or narrow esophagus with thin esophageal mucosa without signs of EoE), and 20 patients undergoing upper endoscopy for upper gastrointestinal or with dysphagia but without features of EoE (controls) at a single medical center from 2015 through 2018.
Aquaporin changes in compound 48/80 induced inflammatory sublaryngeal edema in rat.

Objectives/hypothesis: Laryngeal edema is a common clinical condition. However, the underlying molecular mechanisms remain elusive. Aquaporins (AQPs) are small integral plasma membrane proteins that transport water across the plasma membrane.

The duodenal lumen is exposed to aggressive factors with a high potential to cause damage to the mucosa. Bicarbonate secretion by the duodenal mucosa is accepted as the primary important defense mechanism against the hydrochloric acid intermittently expelled from the stomach. The present work concerns both the influence of the central nervous system and the effects of the hormone melatonin on duodenal bicarbonate secretion in anesthetized rats in vivo as well as effects of melatonin on intracellular calcium signaling by duodenal enterocyte in vitro examined in tissues of both human and rat origin.
