PURPOSE To investigate the caustic ingestion in children among different continents according to demographic characteristics (core purpose), main symptoms, common caustic agents, signs and symptoms, management, treatment and complications. METHODS This systematic review was performed by searching the databases Science Direct, ProQuest, Google Scholar, and PubMed, electronically and manually. ...
SUMMARY Scolicidal agents are used by most surgeons during operations for hydatid cysts when these agents are injected into the cys t cavity, they can pass through the communicating passages between the cyst and bile ducts into the large intrahepatic and extrahepatic bile ducts and because of their caustic nature, they have the potential to damage the epithelium of ducts. This epithelial da...
BACKGROUND Caustic ingestions are rare but potentially life-threatening events requiring multidisciplinary emergency approaches. Although particularly respiratory functions may be impaired after caustic ingestions, studies involving acute emergency care are scarce. The goal of this study was to explore acute emergency care with respect to airway management and emergency department (ED) infrastr...
Background: Sulfur compounds must be removed from petroleum because they contribute to environmental pollution. A strong alkaline solution such as caustic soda is used to remove these compounds. This spent caustic has high values for chemical oxygen demand (COD) concentration, pH and total sulfur. In this study, the regeneration and treatment methodology of sulfidic spent caustic was inve...
Inverse caustic problem, that is computing the geometry of a reflector and/or refractor based on a given caustic pattern, is currently not widely studied. In this paper, we propose a technique to solve the inverse caustic problem in which we compute the geometry of a semi-transparent homogeneous refractive object (caustic object) given a directional light source and a set of caustic patterns (e...
background: the term caustic generally refers to alkaline and the term corrosive generally refers to acidic agents' injury however, in medical literature caustic is frequently a term applied to both substances. ingested alkali typically damage the esophagus more than stomach or duodenum, whereas acids usually cause more severe gastric injury. since esophagus has a slightly alkaline ph, its...
Digestive injury and complications resulting from caustic ingestion is the most challenging clinical situations encountered in gastroenterology. The commonest chemicals implicated in gastrointestinal caustic injury are alkaline and acid agents. The caustic ingestion is voluntarily and in suicidal intent in the most situations in adult .In fact, successful management of these patients requires m...
Ingestion of caustic substances and its long-term effect on the gastrointestinal system maintain its place as an important public health issue in spite of the multiple efforts to educate the public and contain its growing number. This is due to the ready availability of caustic agents and the loose regulatory control on its production. Substances with extremes of pH are very corrosive and can c...
OBJECTIVE Acute poisonings with caustic substances can cause severe chemical injuries to the upper gastrointestinal tract, which can be localized from the mouth to the small intestines. They are seen very often among young people in their most productive years. The aim of this study is to examine the influence of patient's age on the mortality rate and survival of patients with acute caustic po...
Background: Ingestion of caustic agents can cause serious damages of the upper gastrointestinal tract and in some cases this kind of poisoning may have fatal outcomes. Acute caustic intoxications are one of the main problems in the modern clinical toxicology since they mainly affect young people with psychic disorders, suicidal intent, and alcohol addiction. Text: In diagnostic evaluation of th...
