Corrosive chemical substance ingestions are a major problem, especially in developing countries, but also in developed countries such as the United States, France, and Belgium. Ingestions may be deliberate as suicide attempts (mostly in adolescents and adults) or accidental (mostly in children). The results can be devastating in terms of individual suffering and disability, but also in terms of resource utilization and costs. In developing countries, outcomes may be worse because of limited medical/surgical resources. Common sequelae include gastrointestinal (GI) tract (esophagus, stomach, pylorus, and duodenum) stricture formation, GI tract perforation, and hemorrhage. Systemic effects may also occur, such as disseminated intravascular coagulation (DIC), multi-organ system failure, and sepsis. Various interventions in the acute phase to reduce the severity of injury have been attempted, but there are no large controlled clinical trials to demonstrate efficacy. Dilation therapy in various forms is commonly used for the treatment of strictures and a variety of surgical procedures including esophagectomy and delayed replacement may be required in severe corrosive injury cases.

Introduction: Oven cleaning products contain corrosive substances, typically sodium or potassium hydroxide., Objective: To determine the reported toxicity from exposure to oven cleaning products., Methods: Telephone enquiries to the UK National Poisons Information Service regarding oven cleaning products were analysed retrospectively for the period January 2009 to December 2015., Results: There were 796 enquiries relating to 780 patients. Ninety-six percent of the products involved in the reported exposures contained sodium hydroxide and/or potassium hydroxide. Ingestion alone (n = 285) or skin contact alone (n = 208) accounted for the majority of cases; inhalation alone (n = 101), eye contact alone (n = 97), and multiple routes of exposure (n = 89) accounted for the remainder. Ninety-five percent of patients exposed by inhalation, 94% exposed dermally and 85% reporting eye exposure, developed features of toxicity. Patients exposed by multiple routes developed symptoms in 70% of cases. Only 103 of the 285 patients ingested oven cleaner directly, whereas 182 patients ingested food they considered to have been contaminated with oven cleaner. In 100 of the 103 direct ingestions where the features and World Health Organisation/International Programme on Chemical Safety/European Commission/European Association of Poison Centres and Clinical Toxicologists Poisoning Severity Score were known, 56 reported symptoms which were minor in 51 cases. The most common features following ingestion were vomiting (n = 26), abdominal pain (n = 22) or pharyngitis (n = 15). Skin burns (n = 91) predominantly involving the hands or arms, occurred in 44% of dermal exposures. Following inhalation, patients frequently developed respiratory features (n = 52) including coughing and chest pain/tightness. Eye pain (n = 43) and conjunctivitis (n = 33) commonly occurred following ocular exposure., Conclusions: Most (71%) patients exposed to an oven cleaner irrespective of the route of exposure developed features of toxicity, though in most cases only minor features developed; moderate or severe features ensued in ∼4%. Those patients exposed dermally, ophthalmically or by inhalation developed features more frequently (≥85%) than those who ingested a product directly (56%).

Introduction: Endoscopic ultrasonography can provide high-resolution images of the gastric wall., Case Report: A 24-year-old woman with severe corrosive gastritis following massive ingestion of an alkaline household chemical was examined with endoscopic ultrasonography using a 20-MHz probe. Endoscopic ultrasonography disclosed diffuse thickening of the entire gastric wall and lack of demarcation of the muscular layer in the antrum. Several weeks after the ingestion, stenosis developed in the antrum and was treated with laparoscopic gastrectomy., Discussion: Endoscopic ultrasonography can provide accurate evaluation of depth of lesions in corrosive gastritis and may be useful in predicting gastric stenosis.

Background: Acute poisonings are frequent causes of admission to emergency departments and these cases may have hazardous outcomes., Methods: In the present study, medical records of 1818 poisoned patients admitted to Uludag University Medical School's Emergency Department between January 1996 and December 2001 were investigated. The age, sex, outcomes of the patients, and type of poisoning are described., Results: . The mean age for females (63% of the patients) was 27 years, whilst the mean age of male patients was 31 years. The major types of poisonings were ingestions of medications (59.6%), mushrooms (3.3%), corrosives (2.5%), organophosphates (3.2%), and methyl alcohol (0.4%). Carbon monoxide accounted for 6.9% of intoxications. Approximately 65% of the patients survived, while the methyl alcohol and corrosive ingestions led to the highest fatality averages (100% and 14.8%, respectively)., Conclusions: The demographic and diagnostic features of acute poisoning cases treated in our hospital are similar to those reported in the literature. Adults and women are in a high-risk group for acute poisonings and medicine poisoning, which is the most common type of poisoning.
