introduction domestic and industrial swallowing of caustic substances can cause acute and chronic injuries. in the acute phase of care, focus is on the immediate control of tissue damage and perforation, and in the chronic phase, the focus is on the treatment of pharyngeal narrowing and impaired swallowing. conclusions treatment of esophageal burn lesions is by immediate and delayed removing of...

BACKGROUND Esophageal stricture due to caustic ingestion is one of the most difficult problems to manage. Esophageal dilations are the usual treatment and they require a great number of sessions in the majority of cases. This implies time, risks for the patient, anguish for the relatives, and very often, frustration for the physician. OBJECTIVES To evaluate the efficacy of the application of ...

approximately 20% of caustic ingestions result in some degree of esophageal injury. alkaline materials are the most frequent corrosive materials ingested.     the physical form and ph of ingested materials play a critical role in the site and type of gastrointestinal injury (ph > 12 or ph < 1.5, crystalline drain cleaners). unlike alkaline solutions, strong acids are bitter, burn on contact and...

Introduction: Potassium Permanganate (KMnO4) is an uncommon cause of caustic ingestion in teenagers and adults; only case reports are found the recent literature. At Ngwelezana Hospital South Africa, KMnO4 not indication for admission. readily available as used most households recommended medicinal purposes by traditional health practitioners. Aim: To ascertain reasons ingestion, extent severit...

Four of nine exoplanets found by microlensing were detected by the resonant caustic, which represents the merging of the planetary and central caustics at the position when the projected separation of a host star and a bounded planet is s ∼ 1. One of the resonant caustic lensing events, OGLE-2005-BLG-169, was a caustic-crossing highmagnification event with Amax ∼ 800 and the source star was muc...

Ingested corrosive agents produce oropharyngeal and gastroesophageal injuries ranging from minor burns to severe necrosis, depending on the agent amount, concentration, and duration of exposure. The aim of this study was to present our patients with corrosive ingestion retrospectively. Four hundred seventy-three children younger than 16 years of age (mean age, 3.7+/-0.1 years) who were admitted...

This paper proposes a robust algorithm to compute caustics caused by multiple reflections and refractions on the GPU. The proposed algorithm solves two problems of previous methods, caustic light leaks and caustic undersampling. In order to eliminate caustic light leaks, terminal photon hits are stored and caustic patterns are reconstructed on the faces of a layered distance map attached to the...

Esophagitis is mainly a consequence of gastroesophageal reflux disease, one of the most common diseases affecting the upper digestive tract. However the esophageal mucosa can also be targeted by some infectious, systemic or chemical conditions. Eosinophilic esophagitis (EoE) is an immune-mediated inflammatory disease, characterized by eosinophilic infiltration in the mucosa. Esophageal localiza...
