Caustic injuries

Limbal stem cell (LSC) deficiency is a frequent and severe complication after chemical injury to the eye. Previous studies have assumed this is mediated directly by the caustic agent. Here we show that LSC damage occurs through immune cell mediators, even without direct injury to LSCs. In particular, pH elevation in the anterior chamber (AC) causes acute uveal stress, the release of inflammatory cytokines at the basal limbal tissue, and subsequent LSC damage and death. Peripheral C-C chemokine receptor type 2 positive/CX3C motif chemokine receptor 1 negative (CCR2+ CX3CR1- ) monocytes are the key mediators of LSC damage through the upregulation of tumor necrosis factor-alpha (TNF-α) at the limbus...

INTRODUCTION: The ingestion of caustic substances into the upper gastrointestinal tract is an unusual but potentially life-threatening problem. AIM: To evaluate the most commonly ingested corrosive substances, and the endoscopic findings, complications, and final outcomes of caustic intake. MATERIAL AND METHODS: This cross-sectional study included 220 inpatient participants with corrosive poisonings during a 3-year period (2017-2019). Data from the national patient electronic system "My term" and from the "Poisoning information centre" at the University Clinic for Toxicology, Skopje were used...

Despite being one of the most debilitating conditions encountered in the field of toxicology, there is a lack of neutralization measures for the toxins involved in acute corrosive poisoning, and this promotes progressive contact injury of deep tissues after poisoning has occurred. Multiple controversies still surround management strategies during the acute phase of poisoning and the long-term follow-up of the patient. Here, we report a severe case of intentional poisoning with nitric acid complicated by extensive injury of the upper digestive tract, multiple stricture formation, and complete dysphagia...

The mortality and morbidity of acute caustic gastric injuries are high. The spectrum of gastric injury due to caustic ingestion varies from hyperemia, erosion, and extensive ulcers to mucosal necrosis. Severe transmural necrosis can be associated with fistulous complications in the acute and subacute phases and stricture formation in the chronic phase. Due to these important clinical implications, timely diagnosis and appropriate management of gastric caustic injury are crucial, and endoscopy plays a pivotal role...

Ingestion of corrosive substances can severely burn the upper digestive tract leading to bleeding or perforation, and may even be life-threatening. Less commonly, damage to the trachea and bronchi is involved. In this paper, a case of corrosive digestive tract injury and lung injury after oral administration of pipeline dredging agent (the main components are hydroxide, sodium carbonate, sodium hypochlorite, etc.) was analyzed. After active rescue treatment, the patient died of massive hemoptysis. It is suggested that serious complications may occur after ingestion of corrosive substances...

Human exposures to "fire color changing" agents containing copper salts (CS) are rare. We report the case of an intentional mixed CS ingestion with resulting corrosive gastrointestinal injury absent classic laboratory abnormalities. A 23-year-old male with a history of bipolar disorder presented to the emergency department two hours after intentional ingesting an unknown quantity of the fire colorant "Mystical Fire," which contains cupric sulfate (CuSO4 ) and cupric chloride (CuCl2 ). He subsequently developed nausea and abdominal pain and had several episodes of vomiting...

Caustic or corrosive substance ingestion that results in severe esophageal and gastric lacerations frequently requires surgical management. The most common sequelae after an upper gastrointestinal tract caustic injury include non-responding luminal strictures, which are subject to esophageal replacement. Late corrective surgery may include esophagectomy with gastric pull-up and jejunal or colonic interpositions. Although long-segment esophageal reconstruction with jejunum is technically feasible and has demonstrated good outcomes, the complexity of the surgery has precluded the widespread use of this procedure in low- and middle-income countries...

Promethazine, a common antiemetic, can cause severe tissue injury with intravenous (IV) injection. Dihydroergotamine (DHE), commonly used for the acute treatment of migraine, can cause arterial vasoconstriction. We report a rare complication of brachial artery vasospasm in a patient receiving IV promethazine and DHE sequentially through the same midline IV catheter. A 40-year-old woman with history of migraine headaches and Raynaud phenomenon was admitted for treatment of status migrainosus with scheduled IV DHE infusions...

BACKGROUND: Caustic substance ingestion is a high-risk medical emergency associated with high mortality and morbidity. To date, there are several treatment options with no standard method of care. CASE PRESENTATION: We report a case of a corrosive agent ingestion complicated with third-degree burns and severe stenosis of the esophagus and gastric outlet. After failure of conservative treatment, the patient underwent jejunostomy placement for nutritional support followed by transhiatal esophagectomy with gastric pull-up and intra-thoracic Roux-en-Y gastroenterostomy with good outcomes...

INTRODUCTION: The main mechanism of death and the pathological appearance of cases of benzyl alcohol intoxication has not been fully investigated. Autopsy reports of cases of benzyl alcohol intoxication have not been published. CASE PRESENTATION: A 24-year-old man was found in the state of cardiopulmonary arrest at a construction site. He had been performing paint stripping. He was immediately transferred to the hospital, but he did not recover. An autopsy showed focal coloring of the skin without any major caustic injury...

Rectitis caused by the administration of a caustic enema is uncommonly encountered in routine clinical practice. The reasons given for the application of caustic enemas are diverse, including but not limited to suicide attempts, murder attempts, iatrogenic causes and simple mistakes. When caustic enemas do occur the consequences can be dire, resulting in extensive injury. These injuries often prove fatal in the short term, but if the patient survives the initial injuries, they may subsequently cause severe disability...

Extravasation is the leakage of intravenous solutions into surrounding tissues, which can be influenced by drug properties, infusion techniques, and patient-related risk factors. Although peripheral administration of vesicants may increase the risk of extravasation injuries, the time and resources required for central venous catheter placement may delay administration of time-sensitive therapies. Recent literature gathered from the growing use of peripheral vasopressors and hypertonic sodium suggests low risk of harm for initiating these emergent therapies peripherally, which may prevent delays and improve patient outcomes...

Ingestion of caustic agents by children is a serious health issue that can affect the patient for the rest of his life. The role of sucralfate in preventing stricture caused by caustic agents is controversial, and limited studies have been conducted in this field. We aimed to investigate the effect of sucralfate on preventing esophageal stricture in children. Sixty children with mean age of 36.69 ± 20.50 months and grade II B esophageal burns due to ingestion of caustic agents were enrolled in the study...

INTRODUCTION: The incidence of corrosive esophagitis, also known as caustic esophagitis in children, is still increasing in developing countries, according to different clinical reports. Acids and alkalis are, in the same manner, involved in the pathogenesis of corrosive esophagitis in children. The aim of our study was to determine the incidence and endoscopic grading of corrosive esophagitis in a cohort of children from a developing country. MATERIALS AND METHODS: We performed a retrospective analysis of all pediatric patients who were admitted for corrosive ingestion at Pediatric Clinic II, Emergency Hospital for Children, Cluj-Napoca, over 10 years...

Tetracyclines are a class of broad-spectrum bacteriostatic antibiotics used to treat many infections, including methicillin-resistant Staphylococcus aureus (MRSA), acne, pelvic inflammatory disease, chlamydial infections, and a host of zoonotic infections. These drugs work by inhibiting protein synthesis in bacterial ribosomes, specifically by disallowing aminoacyl-tRNA molecules from binding to the ribosomal acceptor sites. While rare, tetracycline antibiotics, particularly minocycline and doxycycline, are associated with an increased risk of developing esophageal perforation and pseudotumor cerebri (PTC, or idiopathic intracranial hypertension)...

OBJECTIVE: We sought to describe skin injuries associated with unapproved topical mole and skin tag removers containing concentrated salicylic acid, Sanguinaria canadensis , or other caustic agents. METHODS: We identified skin injuries associated with unapproved non-device topical mole and skin tag removers reported to the US Food and Drug Administration (FDA) through October 30, 2021 or described in Amazon consumer product reviews between 2019 and 2021. RESULTS: We identified 38 cases, including 30 from Amazon consumer product reviews and eight reported to the FDA...

AIM: The main indications for an esophageal replacement (ER) are unresolved complex esophageal atresia (EA) and caustic strictures (CS). The use of different organs for replacement has been described. When the stomach is chosen, there are two ways to do a gastric pull-up: a partial (PGP) or a total pull-up (TGP). Few studies have been published comparing the different techniques. The aim of this study was to compare the outcomes of patients who underwent ER by PGP or by TGT. METHODS: The medical records of all patients who underwent gastric pull-up for ER in the last 18 years at the National Pediatric Hospital Prof...

Esophageal thermal injury is one of the most feared risks of ablation of the posterior left atrium despite the various devices used to monitor esophageal temperature or deviate the esophagus. Reactive cooling, in which cold water is manually instilled into the esophagus via an orogastric tube in response to rises in luminal esophageal temperature (LET), has been used by operators, but the availability of a dedicated esophageal cooling device offers the ability to provide proactive esophageal cooling without having to react to individual temperature rises in the esophagus...

The esophagus is a deeply located organ which traverses the neck, the thorax, and the abdomen and is surrounded at each level by vital organs. Because of its positioning injuries to the esophagus are rare. Their common denominator is the risk of the organ perforation leading to spillage of digestive contents in surrounding spaces, severe sepsis and eventually death. Most frequent esophageal emergencies are related to the ingestion of foreign bodies or caustic agents, to iatrogenic or spontaneous esophageal perforation and external esophageal trauma...
