Ingestion of Portland Cement

The Journal of Emergency Medicine, 2015
The common toxicities of cement are allergic dermatitis, abrasions, and chemical burns, but reports of cement ingestion are rare. In this study, we report a case of successful treatment of cement ingestion using emergency gastrointestinal endoscopy.An 83-year-old female was admitted to the emergency department with altered mental state and abdominal ...
