Accidental ingestion of caustic substances (acid and alkali) occurs more frequently in children than in adults. The subsequent injury varies from minimal to severe, with perforation and even death as potential complications. Several factors have been shown to mediate the severity of injury, including the pH, concentration and physical state of the ingested substance, tissue contact time, and quantity (volume) of the ingested material. Liquids with a pH of less than 2 (acidic) or a pH of greater than 12 (alkali) are considered to be extremely corrosive and hold the greatest risk for injury. Esophageal injury after caustic ingestion is endoscopically graded with a score of 0 for no injury to IIIb for significant circumferential injury with ulcers and necrosis. Ingestion of either a strong alkali or acid has been documented to result in esophageal necrosis and ulcers (grade IIIb). Alkali ingestions occur more frequently because of their presence in daily life (detergents, degreasers) and therefore have more reports of injury. Despite more than 8200 documented cases of topical salicylic acid ingestions annually in US children younger than 19 years, there are no reported cases of salicylic acid resulting in gastrointestinal pathology. We report 2 cases of salicylic acid ingestion resulting in esophageal strictures. Both patients had more significant injury than anticipated given their initial clinical presentations. Given our recent experience, we recommend close follow-up and evaluation for strictures in patients with exposure to salicylic acid.

UI MeSH Term Description Entries
D007223 Infant A child between 1 and 23 months of age. Infants
D008297 Male Males
D011041 Poisoning A condition or physical state produced by the ingestion, injection, inhalation of or exposure to a deleterious agent. Poisonings
D002057 Burns, Chemical Burns caused by contact with or exposure to CAUSTICS or strong ACIDS. Chemical Burns,Burn, Chemical,Chemical Burn
D002404 Catheterization Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions. Cannulation,Cannulations,Catheterizations
D002424 Caustics Strong alkaline chemicals that destroy soft body tissues resulting in a deep, penetrating type of burn, in contrast to corrosives, that result in a more superficial type of damage via chemical means or inflammation. Caustics are usually hydroxides of light metals. SODIUM HYDROXIDE and potassium hydroxide are the most widely used caustic agents in industry. Medically, they have been used externally to remove diseased or dead tissues and destroy warts and small tumors. The accidental ingestion of products (household and industrial) containing caustic ingredients results in thousands of injuries per year. Caustic,Corrosive,Corrosives
D002675 Child, Preschool A child between the ages of 2 and 5. Children, Preschool,Preschool Child,Preschool Children
D003102 Colloids Two-phase systems in which one is uniformly dispersed in another as particles small enough so they cannot be filtered or will not settle out. The dispersing or continuous phase or medium envelops the particles of the discontinuous phase. All three states of matter can form colloids among each other. Hydrocolloids,Colloid,Hydrocolloid
D003680 Deglutition Disorders Difficulty in SWALLOWING which may result from neuromuscular disorder or mechanical obstruction. Dysphagia is classified into two distinct types: oropharyngeal dysphagia due to malfunction of the PHARYNX and UPPER ESOPHAGEAL SPHINCTER; and esophageal dysphagia due to malfunction of the ESOPHAGUS. Dysphagia,Swallowing Disorders,Esophageal Dysphagia,Oropharyngeal Dysphagia,Deglutition Disorder,Disorders, Deglutition,Dysphagia, Esophageal,Dysphagia, Oropharyngeal,Swallowing Disorder
D003879 Dermatologic Agents Drugs used to treat or prevent skin disorders or for the routine care of skin. Agent, Dermatologic,Agent, Dermatological,Agents, Dermatologic,Dermatologic Agent,Dermatological Agents,Agents, Dermatological,Dermatological Agent
