Objectives: This study aims to examine patients who developed acute pesticide poisoning while spraying or using pesticide and presented to the emergency department in hospitals in Chungcheongnam-do Province. Based on the findings, this study will provide implications for safety and health management pertaining to the use of pesticides. Methods: Pesticide poisoning data collected by the Chungnam Center for Farmers' Safety and Health from 2014 to 2018 was cross-sectionally analyzed. A total of 331 patients with pesticide poisoning presented to one of hospitals and four of medical centers in the region(Dankuk University Hospital, Gongju and Hongsung, Cheongyang, Cheonan Medical Center). Seventeen of these patients (15 men and two women) developed poisoning while spraying pesticide. The patients' charts were reviewed to collect data on pesticide poisoning, namely currently working in farming-related occupation, means of transportation to the hospital, place of poisoning, symptoms of acute pesticide poisoning, treatment, pesticide used when poisoning occurred, and classification by technical ingredients. Results: Fifteen out of 17 patients who developed poisoning while spraying pesticide were men. Insecticide was used in 35.3% of the cases, and herbicide was used in 29.4% of the cases, which was different from cases of poisoning from ingestion poisoning. The major symptoms were vomiting (35.3%), nausea (29.4%), dizziness (29.4%), and headache (23.5%). A total 11 ingredients were identified in 12 patients, and the most common ingredient was glyphosate, which is an herbicide. Most patients showed a state of mild toxicity, but two patients showed a state of severe toxicity. These patients respectively used glyphosate and paraquat. Conclusions: Our findings can be useful for suggesting the need for a national healthcare system to manage occupational pesticide poisoning among farmers. Further, these findings can be used to increase the awareness of the risk of acute poisoning during pesticide spraying and suggest the need for a safety health education to increase farmers' awareness of pesticide poisoning.

Because of the ready availability of aspirin, salicylate poisoning remains a common problem in many countries. Another potential source of salicylate poisoning is medicated oil containing methyl salicylate (oil of wintergreen). Methyl salicylate poses a much greater safety threat than aspirin tablets because of its liquid, concentrated form and high lipid solubility. Because of this danger, the toxic potential of medicated oil containing methyl salicylate should be fully appreciated both by physicians and by the general public. We encountered two cases of salicylate poisoning resulting from accidental ingestion of Chinese medicated oil. We report these cases along with a review of the literature.

Purpose: This study examined the clinical characteristics of severe elderly poisoning patients to determine the factors that can prevent them. Methods: Data were collected from patients over 65 years of age presenting to the emergency center with poisoning from 2013 to 2018. Their medical records were analyzed retrospectively, and patients with a poisoning severity score of three or more were defined as the severe poisoning group. The risk factors were evaluated by univariate and multivariate analysis. Results: This study analyzed 292 patients, of whom 37 (12.7%) belonged to the severe poisoning group. The severe poisoning group showed a significantly higher association with pesticide poisoning and intentional suicide attempts. Loneliness and somatization were the cause of the suicidal ideas. No significant differences in age, sex, drinking, ingestion time, poisonous materials other than pesticides, and neuropsychological consultation were observed between the two groups. Conclusion: The severe elderly poisoning patients were the result of intentional poisoning for suicide. Loneliness and somatization were the most influential causes of suicidal poisoning. Therefore, psychiatric screening and frequent medical treatment for elderly people are required to prevent severe poisoning in elderly patients.

Purpose: Toxic Exposure Surveillance System (TESS) is widely used for poisoning data collection and making a counterplan. But, there were few reports about poisoning data collection using TESS in Korea. The aim was to collect poisoning data using TESS report form and investigate the recognition of emergency physician about the necessity of TESS as preliminary survey. Methods: Retrospectively, we gathered data from hospital records about the patient who admitted hospital emergency room due to poisoning. Date were gathered by paper and/or web client system report form in patients recruited by ICD-10 codes Results: From Jun 2004 to May 2005,3,203 patients were enrolled in 30 hospitals and their mean age was $44.9{\pm}20.3years$ old(male: female = 1,565: 1,638). The most frequent site of exposure was their own residence (73.2%, 2,345/3,203) and most of reported patients were older than 20 years(89.7%, 2,871/3,203). Frequent substances involved in poisoning were medication(41.9%) and pesticide(33.3%). Intentional poisoning was 60.7%(1,954). In fatality, overall frequency was 5.1%(162/3,203) and the most frequent route of exposure was ingestion(96.3%, 156/162) and the most frequent substance was pesticide(85.2%, 138/ 162). Antidotes were administered in 202 patients(2-PAM, atropine, antivenin, N-acetylcystein, vitamin K, flumazenil, ethanol, methylene blue, naloxone, calcium compound). 19 of 20 emergency physicians agreed with necessity of TESS. Conclusion: Data collection using TESS report form showed preliminary poisoning events in Korea. Frequent poisoning substance were medication and pesticide. The fatality was mainly related with pesticide ingestion. Many doctors in emergency room recognized the necessity of TESS.

Purpose: Poisoning is a major health problem for the elderly, and poisoning can cause fatal side effects. However, the characteristics and clinical features of elderly patients with acute poisoning have not been well studied in the previous domestic research. So, we tried to analyze the clinical characteristics and toxic substances of the patients who were 65 years old or older and who were admitted to the regional emergency medical center due to acute poisoning. Methods: We retrospectively reviewed the medical records and poisoning protocols of the patients who were 65 years of age or older and who had with acute poisoning and who visited the ED in our emergency center from January 2005 to December 2009. We collected the demographic information, the gender, the underlying diseases, the causes and toxic substances, the initial presentation, the treatment and the outcomes. Results: A total of 2179 poisoned patients visited the hospital during 5 years, and among them 244 were 65 years of age or older (11.2%). The mean age was $75.6{\pm}6.9$ years and the male:female ratio was 1:1.7. The most common cause of poisoning was suicide (73.4%) and the most common source of poisonous substances was their own drugs. Of the substances used for poisoning, benzodiazepine was the most common drug (25.8%), followed by sedatives other than benzodiazepine (25.4%), insecticide (12.7%), chemical agents (12.3%) and herbicides (8.2%). The most common initial presentation was mental change (64.8%). When comparing the factors between the three elderly groups, there was no difference in gender, the cause, the substances and the underlying disease. The outcomes of treatment included ICU admission (56.1%), a good condition at discharge (12.7%) and admission to a general ward (12.7%). The overall mortality rate was 10.2% for the elderly patients. Conclusion: In this Korean study, unlike the foreign studies, the most common cause of poisoning in elderly patients was intentional poisoning. The admission rate was 68.8% and mortality rate was 10.2%.

Purpose: This study aimed to compare the clinical features of methanol and ethylene glycol poisoning. Methods: This single-center retrospective observational study included patients with toxic alcohol poisoning who visited a regional emergency medical center. Patients with methanol and ethylene glycol poisoning from January 2004 to June 2023 were selected for the study using diagnostic codes. Results: Twenty-two patients with toxic alcohol poisoning visited during the study period, with 11 patients for each category. Compared to methanol poisoning, ethylene glycol poisoning patients were more likely to have consumed alcohol for suicidal purposes (n=4 [36.36%] vs. n=8 [72.73%]) and were more likely to be drowsy (n=0 vs. n=6 [54.55%], p=0.016). The anion gap (25.43±8.35 mmol/L vs. 13.22±6.23 mmol/L, p=0.001) and lactic acid levels (1.785 [1.3-2.785] mmol/L vs. 9.90 [4.20-11.81] mmol/L, p=0.007) were higher in ethylene glycol poisoning patients than in methanol poisoning patients. Among alcohol dehydrogenase blockers, oral ethanol was administered to 10 patients (45.45%) (n=4 [36.36%] vs. n=6 [54.55%]), and intravenous ethanol was administered to six patients (n=4 [36.36%] vs. n=2 [18.18%]). Fomepizole was administered to two patients (9.09%) each, and renal replacement therapy was non-significantly more common in patients with ethylene glycol poisoning (n=8 [72.73%] vs. n=3 [27.27%], p=0.128). Three patients had delays in diagnosis and treatment, and while there were no fatalities, one patient was left with permanent vision damage. Conclusion: Because these are uncommon types of poisoning and the clinical presentation is difficult to recognize early, healthcare providers should be familiar with toxic alcohol types and screen for them to ensure proper diagnosis and treatment.

Objective: South Korea still lacks systematic national poisoning data collection or a poison control center (PC). The objectives of this study are to provide estimates of poisoning incidents in South Korea and to stress the necessity of a national poisoning surveillance framework managed by a national PC. Method: The number of poisoning incidents was estimated based on the 2018 annual report of the American Association of Poison Control Centers' National Poison Data System (NPDS). Our estimation of poisoning data was classified according to age group, reason for poison exposure, and case management site. Results: Total poisoning cases estimated numbered 326,636, which is tantamount to 631 cases per 100 thousand. Poisoning cases among those younger than five years old accounted for 71.7% in the United States. Fatal poisoning cases were estimated to be 210.63 (95% CI: 199.70-222.15). Non-intentional poisoning cases (250,378 cases, 95% CI: 249,992-250,764, 76.7%) were estimated to be far higher than intentional cases (62,399 cases, 95% CI: 62,207-62,593, 19.1%). Conclusion: Our results can be used to suggest the necessity of producing national poisoning data and establishing a PC despite the uncertainty of estimation.

We described the successful treatment of cases of lead poisoning in a Whooper swan (Cygnus cygnus) and a Cinereous vulture (Aegypius monachus) in Korea. The swan and vulture rescued were diagnosed with lead poisoning based on clinical signs, the presence of suspected lead-like particles in the ventriculus detected by radiography and elevated blood lead levels. Endoscopic retrieval for the swan and gastric lavage for the vulture were used to remove the lead respectively. After the removal of lead particles, a course of chelation treatment was administrated. This would be the first report of successfully treating wild birds with lead poisoning in Korea.

This is a clinical report of one patient with mental disorientation, abnormal behavior, spasm, and other symptoms caused by poisoning with Xanthii Fructus, who recovered completely with treatment. The patient was treated with Korean medical treatments, such as herbal medicine and acupuncture. After treatment, various symptoms caused by the Xanthii Fructus poisoning disappeared completely and laboratory findings, such as liver function tests (aspartate transaminase and alanine transaminase), were also close to the normal ranges. This case shows that Korean medicine therapy can be applicable in treating various symptoms caused by Xanthii Fructus poisoning. It is considered that further research is needed to confirm the safe use of Xanthii Fructus.

Purpose: There has been no nationwide surveillance survey of poisoning cases in Korea. This study examined the clinical characteristics of poisoning admissions in order to obtain preliminary data for future planning. Methods: This study retrospectively reviewed the data on poisoning admissions of 150 hospitals based on the hospital discharge injury surveillance data of Center for Disease Control and Prevention in Korea from January to December in 2004. The demographic data, poisons used, causes of poisoning, reasons for attempted suicide and mortality rate was investigated according to the age group. The factors associated with mortality were also evaluated. Results: A total 836 patients admitted for poisoning were analyzed. Their mean age was $46.5{\pm}19.5$ years (male 415, female 421). The most frequent age group was the 4th and 5th decades. The most common poisons involved were pesticides (45%) and medications (23%). The majority (64%) involved intentional poisoning except for those in the 1st decade. The most common reason for the attempted suicide was family problems. However, individual disease was the most common reason in those over 60 years. The overall mortality rate was 8.7% (73/836). Pesticides and being elderly (over 65 years old) were strongly correlated with fatality. Conclusion: The incidence of intentional poisoning increases from the 2nd decade making it a preventable injury. "Overall, the incidence of intentional poisoning increases from the 2nd decade". Therefore, there is a need to frame a prevention policy corresponding to each factor related to fatality, such as an elderly population and pesticides.
