- Purpose: There are an insignificant number of studies done on the demographics of intoxication patients and on the characteristics of toxic exposure on a long term basis in Korea. The objective of our survey is to investigate the epidemiologic characteristics of intoxication in a metropolitan emergency department in order to more efficiently manage intoxication patients. Methods: We retrospectively reviewed the medical records of intoxication patients who visited the emergency department of a high end medical facility between January, 1998 and June, 2009. We investigated the trend of the substances people became intoxicated with during the study period and we analyzed the age, gender, year and distribution of patients and the outcome of the patients. Results: There were 1544 cases of intoxication during the study period, and the cases made up 0.37% of the total visitors to our emergency department, which is a high end medical facility located in the city. Most of the patients were female (70%) in their twenties and thirties. The most commonly ingested intoxication substances were sedatives, analgesics and pesticides. Unlike in the province, antidepressant abuse is on the rise while pesticide abuse is falling. The overall admission rate was 24.8% and the mortality rate was 1.6%. Pesticides intoxication was the most common cause of death (76%). Pesticides intoxication, a male gender and old age were the most significant fatality-related factors. Conclusion: We think that there is a need to investigate the actual conditions of drug intoxication in the city and prepare measures to prevent drug intoxication.

- Purpose: Though caustic injury of the upper digestive tract can lead to severe sequelae, there are few clinical studies on this subject. This study was undertaken to evaluate the clinical characteristics, the endoscopic findings and the risk factors of the upper digestive lesions in patient with caustic ingestion injury. Methods: We retrospectively reviewed the medical records of 137 patients who ingested caustic materials and who visited to our emergency room from January, 2000 to June, 2009. Results: The most common ingested agent was sodium hypochlorite (44.5%), followed by acetic acid (19.7%), hydrochloric acid (11.7%) and lye (8.0%). Ingestion for suicidal attempt (62.0%) was more frequent than accidental ingestion (30.7%). Grade IIa injury was the most frequent finding on endoscopy of the esophagus and Grade 1 injury was the most frequent finding on endoscopy of the stomach. For the late sequelae, there were 9 cases (6.6%) of esophageal stricture and 2 cases (1.5%) of gastric outlet obstruction. The initial signs and symptoms did not correlate with the development of stricture, but leukocytosis, and grade III injury were related to the risk of developing stricture. Conclusion: Caustic injury of the upper gastrointestinal tract is frequently observed on early endoscopy and it can cause significant late sequelae such as stricture. Therefore, it is necessary to evaluate these patients with regular follow up endoscopic examinations for the management of late sequelae.
