Clinical Profile and Outcome of Organophosphorus Poisoning in a Tertiary Hospital.

Organophosphorus compound (OPC) poisoning is common in Bangladesh. The toxicity of the agent and paucity of appropriate medical services has resulted in high mortality rates. To find out the clinical profile and outcome of OPC poisoning patients is the main aim of my study. This descriptive cross-sectional study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Bangladesh from September 2016 to November 2018. In this study, mean age of the study subjects was 25.90±11.24 years. Males (70.8%) were predominant than female (29.2%). In this study, most of the poisoning was done by ingestion (98.3%) and only two (1.7%) by inhalation. Regarding features, most muscarinic effect was constricted pupil and bronchospasm (65.0%). Common nicotinic effect was fasciculation (25.0%) and central effect was headache (61.67%). Mean amount of OPC ingestion was 26.30±17.24 ml in this study. Regarding circumstances of poisoning, familial disharmony (38.3%) and quarrel with other family members (37.5%) were the major reason followed by failure of personal affairs (15.0%) and other reasons (9.2%). Regarding complications, aspiration pneumonia was found in 6.7% cases, cardiac arrhythmia was in 6.7% cases and intermediate syndrome was in 1.7% cases. Most of the study subjects (95.0%) recovered fully. Most of the patients were from rural area. Suicidal was the common motive and familial disharmony and quarrel with other family members are the common circumstances of poisoning. Mortality rate was 5.0%.

Clinical presentation and management of methanol poisoning outbreaks in Riyadh, Saudi Arabia: a retrospective analysis.

BACKGROUND: Acute methanol intoxication, whether unintentional or deliberate, necessitates prompt intervention to prevent severe morbidity and mortality. Homemade alcoholic beverages are a frequent source of such poisoning. This retrospective analysis examined two outbreaks of methanol intoxication in Saudi Arabia. It investigated the clinical presentation, implemented management strategies, and any lasting complications (sequelae) associated with these cases. The aim was to assess the potential impact of different treatment modalities and the timeliness of their initiation on patient outcomes. METHODS: This was a retrospective case series of methanol poisoning cases which presented to the adult emergency department (ED) at King Abdulaziz Medical City (KAMC) in Riyadh, Saudi Arabia. There were two separate outbreaks in the city, the first one was from September 1 to September 10, 2020 and the second one was from May 14 to May 20, 2021. Electronic charts were reviewed, and data were extracted to previously prepared data extraction sheets. RESULT: From the 22 patients who arrived in the ED alive, the most common complaints were nausea or vomiting followed by altered level of consciousness. About 9% from the patient were hypotensive, 36% were tachycardic, 41% were tachypneic and 4% were having SpO2 < 94%. Brain CT was abnormal in 6 patients. Vision impairment was the most common sequalae of methanol poisoning (7 out of 12 patients who were assessed by ophthalmologist, 58%). When the patients were divided based on severity (mild, moderate, severe), nausea or vomiting and loss of consciousness were the most common complaints among the moderate group while loss of consciousness predominated in the severe group. Two patients presented with low blood pressure and were in the sever group. The severe group had a mean Glasgow Coma Scale (GCS) of 8. Most of the patients in the severity groups underwent the same management apart from those who died or deposited. Eight patients in the severe group had to be intubated. CONCLUSION: This study demonstrates the multifaceted clinical presentation of methanol poisoning, culminating in a 17.4% mortality rate. Notably, our findings emphasize the critical role of prompt diagnosis and swift initiation of combined fomepizole therapy and hemodialysis in mitigating mortality and minimizing the potential for chronic visual sequelae associated with methanol poisoning.

Fomepizole use reported to United States Poison Centers from 2010 to 2021.

BACKGROUND: The diagnosis of toxic alcohol poisoning is often based on clinical presentation and nonspecific surrogate laboratory studies due to limited testing availability. Fomepizole is the recommended antidote and often administered empirically. The objective of this study is to identify substances that mimic toxic alcohols and compare key clinical factors between toxic alcohol and non-toxic alcohol exposures when fomepizole was administered. METHODS: This study was a retrospective evaluation using the National Poison Data System from January 1, 2010 through December 31, 2021. Exposures were included if fomepizole was administered. Toxic alcohol exposures had ethylene glycol or methanol as a coded substance. For exposures not coded as a toxic alcohol, the first substance was described. Paracetamol (acetaminophen) exposures from 2020 and 2021 were excluded. RESULTS: Fomepizole was reportedly used 25,110 times over 12 years. Use increased from 1,955 in 2010 to 2,710 in 2021. Most administrations were for reported toxic alcohol poisoning (60 percent) but use in reported non-toxic alcohol poisoning was greater starting in 2020. Toxic alcohol exposures were older (43.3 versus 39.8 years; P < 0.001) and more likely male (65.7 percent versus 58.2 percent). Level of care was mostly a critical care unit (67.7 percent), which was less common in toxic alcohol (63.3 percent) than non-toxic alcohol exposures (74.2 percent). The most common non-toxic alcohol substances were ethanol (24.9 percent) or an unknown drug (17.5 percent). Acidosis, increased creatinine concentration, anion gap, and osmolal gap, and kidney failure were coded in a lower proportion of toxic alcohol exposures than non-toxic alcohol exposures (P < 0.001). DISCUSSION: The inability to provide rapid clinical confirmation of toxic alcohol poisoning results in the empiric administration of fomepizole to many patients who will ultimately have other diagnoses. Although fomepizole is relative well tolerated we estimated that this practice costs between $1.5 to $2.5 million. The major limitations of this work include the biases associated with retrospective record review, and the inability to confirm the exposures which may have resulted in allocation error. CONCLUSION: Most fomepizole use was for a presumed toxic alcohol. This recently shifted to greater use in likely non-toxic alcohol poisoning. Key difference between the groups suggest fomepizole administration was likely due to the difficulty in diagnosis of toxic alcohol poisoning along with the efficacy and safety of fomepizole. Increased toxic alcohol laboratory testing availability could improve timely diagnosis, reserving fomepizole use for toxic alcohol poisoning.

Clinical analysis of acute poisoning in children.

OBJECTIVE: The clinical characteristics of hospitalized children with acute poisoning were analyzed to provide a reference for preventing poisoning and seeking effective prevention and treatment. METHODS: The clinical data of 112 children with acute poisoning admitted to Qilu Hospital of Shandong University from January 1, 2018, to December 31, 2021, were collected and analyzed from different perspectives. RESULTS: The majority of acute poisoning cases that occurred in children were in early childhood and preschool age (89 cases, accounting for 79.4%). The most common types of poisoning were pesticide poisoning and drug poisoning, and the main ways of poisoning were accidental administration via the digestive tract and accidental ingestion. Poisoning occurred slightly more in spring and summer all year round, and most children had a good prognosis after timely treatment. CONCLUSION: Acute poisoning often occurs in children. Parental education and intensified child supervision are needed to prevent the incidence of unintentional poisoning.

[Investigation and analysis of acute poisoning of organic fluorine mixed gas in a fluorine polymerization plant].

In January 2021, an acute chemical poisoning incident occurred at a fluorine polymerization plant. Through the analysis of the occupational health situation of the enterprise, combined with the clinical manifestations of the poisoned patients and the laboratory examination results, it was determined that the incident was an acute poisoning incident caused by the inhalation of organic fluorine mixed gas in the fluorine polymerization plant. Subsequently, it was clarified that the accident was caused by the illegal operation of the employees of the fluorine polymerization plant, which caused the discharge of the organic fluorine mixed gas containing high concentration of octafluoroisobutene, resulting in the poisoning of the on-site construction personnel. In order to avoid the occurrence of similar incidents, enterprises should implement the main responsibility of safety production, regularly organize supervision and inspection, eliminate illegal operations, conduct safety education and training for the staff of the unit and outsourced staff, and improve the emergency rescue ability of sudden poisoning incidents.

Poisoning in children and adolescents in Kermanshah city, Iran.

BACKGROUND: Poisoning among children and adolescents is a public health problem worldwide. To take preventive measures, the pattern of this problem should be determined. This study aimed to describe the demographic characteristics of poisoning in children and to investigate the relationship between the types of poisoning and demographic factors in children in Kermanshah province. METHODS: This cross-sectional, descriptive-analytical study was conducted on 250 children and adolescents under 18 years of age who were referred to Mohammad Kermanshahi Pediatric Hospital in Kermanshah province due to poisoning during 2019-2022. The demographic and epidemiological data of patients were extracted from their medical files and analyzed. RESULTS: Out of 250 cases of poisoning, 173 (69.2%) cases were unintentional, 96 (55.5%) of whom were boys. Further, 77 (30.8%) cases of poisoning were intentional, of whom 49 (63.6%) were girls. There was a significant difference between gender and intentional and unintentional poisonings (p-value = 0.005). The median age of unintentional poisoning was 3 (IQR = 2.5) and that of intentional poisoning was 14 (IQR = 2). Most cases of poisoning were in cities, 145 (83.8%) of them were unintentional and 66 (85.7%) were intentional. Most cases of intentional and unintentional poisonings occurred in spring 2017 (35.1%) and autumn 2016 (34.6%), respectively. The most common causes of poisoning were narcotics (n = 36, 34.3%) and drugs (n = 35, 33.3%) in the age group 0-3 years and drugs (n = 46, 66.9) in the age group 11-18 years. CONCLUSIONS: The most common causes of poisoning were narcotics and drugs in children and drugs in adolescents. To prevent poisoning in children, parents are required to increase their knowledge of the safe storage of narcotics and drugs, such as not storing methadone in a water bottle. Targeted evaluation and preventive measures are also needed in adolescent poisoning.

Self-harm by single- and multi-agent medication poisoning in a retrospective analysis of a Poison Control Center database from January 2018 to December 2022.

PURPOSE: Medication poisoning is the most common method of self-harm. Longitudinal studies incorporating pre- and post-COVID-19 pandemic data are required to describe the phenomenon and to evaluate the long-term impact on mental health. METHODS: Calls to the Poison Control Center of Policlinico Umberto I Hospital - Sapienza University of Rome, Italy, were analyzed retrospectively for characteristics and clinical presentation of cases of interest from January 2018 to December 2022. RESULTS: A total of 756 cases of self-harm by medication poisonings were recorded in the study period. A reduction in rate of cases in 2020 was followed by a return to pre-pandemic levels by 2021. When separately analyzing single- and multi-agent cases, occurrence of cases involving just one medication increased since early 2021, with a peak in 2022 (7.8% of total calls, 95% CI 6.2-9.5, from 4.9%, 95% CI 4.1-5.8 in 2018). This increase in the rate of cases, mostly of none or mild severity, was driven by youth aged 12-21, in which the relative proportion of single- versus multi-agent cases showed an increasing trend since 2020 (from 42.6% in 2018 to 78.6% in 2022). Acetaminophen was the medication most frequently involved and benzodiazepines the largest class. A psychiatric background was increasingly seen in 2022, especially in age group 12-21. CONCLUSION: Single-agent medication self-harm may be an increasingly prevailing phenomenon. Young adolescents with a psychiatric background might be most vulnerable to this behavior in the COVID-19 pandemic aftermath. Healthcare professionals should expect favorable clinical outcome and improve both counseling and psychotherapy supervision in individuals at risk.

Home safety hazards associated with unintentional poisoning among children aged 0-5 years in Mongolia: A case-control study.

OBJECTIVE: To examine the association between home safety hazards and unintentional poisoning in children in Mongolia. METHODS: We conducted a case-control study using structured questionnaires to investigate safety behaviours, safety equipment use, and home hazards in households with or without children aged 0-5 years who had suffered from poisoning at home (i.e., cases and controls). We recruited 190 cases (105 medicinal and 84 non-medicinal poisonings, and one each) at the National Center for Maternal and Child Health and 379 controls in the communities between 1 March and 30 October 2021. RESULTS: There were large differences between cases' and controls' households in safety behaviours and home hazards: the failure to store all medicines out of reach of children (68% of cases vs. 25% of controls), the failure to store all medicines safely (out of reach, locked or non-existent) (61% vs. 22%), the failure to put all medicines away immediately after use (77% vs. 43%), the presence of things that a child could climb on to reach high surfaces (82% vs. 67%), the presence of medicines transferred into different containers (28% vs. 9%) and the presence of household products transferred into different containers (28% vs. 16%). These home safety hazards were strongly associated with poisoning after controlling for confounders. CONCLUSION: Children's risk of unintentional poisoning was strongly associated with the unsafe storage of potentially poisonous agents by caregivers and home hazards. Since unsafe storage is widespread, a fail-safe approach such as child-resistant closure of medicines and household products should be considered.

Suicide poisoning mortality: a comparison of the national poison data system and centers for disease control national dataset.

The America's Poison Centres National Poison Data System (NPDS) is set up for the active surveillance of voluntarily reported poisoning cases in near real-time. The Centres for Disease Control and Prevention (CDC)'s Wide-ranging Online Data for Epidemiologic Research (WONDER) database is final national mortality data from state registries. We compared suicide poisoning deaths in both datasets from 2000 to 2020 and tested their relationship using a simple linear regression model. Mean annual suicide poisoning deaths during the review period were 699 (SD 145) in NPDS, and 6150 (SD 577) in WONDER. NPDS annual cases averaged 11% of cases recorded in WONDER (SD 2%; Range 8%-16%). The regression coefficient for the linear relationship between annual deaths recorded in both datasets was 0.18 (p-value<0.001, R2=0.51). The rapidly available NPDS data on fatal self-poisoning may provide sentinel surveillance regarding self-poisonings, but do not reliably predict final national data on suicide poisoning.

Acute exogenous intoxications in childhood: factors related to hospitalization.

OBJECTIVE: To describe the profile of children assisted in the Emergency Room of a Children reference Hospital in the South of Brazil, victims of acute poisoning between 2016 and 2021, to characterize the toxic agents and to present the factors related to hospitalization. METHODS: Retrospective, descriptive and observational study with data collection from medical records at a children's hospital from July 2016 to June 2021 based on the compulsory notification forms. The characteristics of victims, of the incident, the type and class of the substance involved, the procedures demanded and the need for the Intensive Care Unit were evaluated. The outcome considered was hospitalization. Absolute and relative frequencies were calculated for the categorical variables and measures of central tendency and dispersion for the numerical ones. Binary logistic regression was performed to identify variables related to hospitalization. RESULTS: There were 411 consultations, with the mean age of 7.2±5.5 years, and predominance of females (59.9%). Most of the poisoning occurred at home (82.1%) and orally (93.7%). Chemicals or cleaning products were the main agents in children up to 1 year of age, whereas in the other age groups accidents occurred most frequently with medicines. Hospital admission occurred in 38.7% of the cases, with related variables being: number of agents, type of substance involved, medication that acts on the Central Nervous System, recurrence, motivation (accidental/intentional), and performance of simple exams. CONCLUSIONS: More preventive actions are needed, such as legislation, as well as greater guidance to parents on how to store products in the domestic environment, in order to reduce the number of exogenous intoxications in the pediatric population.

Forty years of National Poison Data System Annual Reports.

INTRODUCTION: The 40th National Poison Data System Annual Report from America's Poison Centers is published in this issue of Clinical Toxicology. This Commentary will focus on changes that have occurred over the years and emerging trends while highlighting some of the strengths and weaknesses of the system. FORTY YEARS OF NATIONAL POISON DATA SYSTEM ANNUAL REPORTS: The National Poison Data System now receives poison exposure data from all 50 states and territories of the United States, representing all levels of care and medical outcomes, and is collected in near real-time. The 2022 report is double in size from the 1983 report and shows changes in the distribution of exposure substances and at least a doubling in the percentage of calls from a health care facility, intentional exposures, and fatalities. There was also a more modest increase in cases managed in a health care facility, and a 40% drop in the percentage of cases managed in those under age 6. While total reported poison center cases have been decreasing since 2008, cases with more serious medical outcomes have steadily increased. To address the decline in the total number of less serious cases, an online tool was initiated for consumers to obtain simple individualized poisoning recommendations as an alternative to directly contacting a poison center. FENTANYL EXPOSURES AND TISSUE CONCENTRATIONS: Fentanyl exposures reported to the National Poison Data System have increased rapidly since 2019, driven by non-prescription fentanyl. Reporting of this was facilitated by the granularity of the generic coding schema and the ability to develop new generic codes rapidly, unlike some other national data sets. Total fentanyl exposures and those with more serious outcomes show a good correlation with national data on fentanyl deaths, demonstrating the ability of the National Poison Data System to function as a surveillance tool. Fentanyl concentrations reported to the National Poison Data System Fatality module showed antemortem concentrations to be slightly lower than postmortem concentrations, little difference between postmortem peripheral and central concentrations, and single substance concentrations slightly higher than cases with multiple substances. STRENGTHS AND WEAKNESSES: Strengths include the breadth of the database, granularity, contemporaneous data collection, near-real-time data submission allowing for automated toxicosurveillance activities, ability to rapidly activate emergency product codes for emerging situations, a robust web-based query tool, mapping of generic codes and clinical effects to other data dictionaries, and review by toxicologists of fatalities to assign a relative contribution. Weaknesses include voluntarily reported, non-verified exposures, interpreting reported medical outcomes (non-toxic and fatalities), lag-time in collecting data on new therapeutic modalities, and mortality data varying from that reported by other sources. CONCLUSION: Poison center data gives a robust, reproducible image of the populations that utilize poison center resources and seems to mirror trends noted from other data sources. This supports the continued need for poison centers in the information age to support the management of patients potentially exposed to poisons and those who are more severely poisoned.

2022 Annual Report of the National Poison Data System® (NPDS) from America's Poison Centers®: 40th Annual Report.

INTRODUCTION: This is the 40th Annual Report of America's Poison Centers National Poison Data System (NPDS). As of 1 January, 2022, all 55 of the nation's poison centers (PCs) uploaded case data automatically to NPDS. The upload interval was 4.72 [4.40, 9.27] (median [25%, 75%]) minutes, effectuating a near real-time national exposure and information database and surveillance system. METHODS: We analyzed the case data tabulating specific indices from NPDS. The methodology was similar to that of previous years. Where changes were introduced, the differences are identified. Cases with medical outcomes of death were evaluated by a team of medical and clinical toxicologist reviewers using an ordinal scale of 1-6 to assess the Relative Contribution to Fatality (RCF) of the exposure. RESULTS: In 2022, 2,483,183 closed encounters were logged by NPDS: 2,064,875 human exposures, 50,381 animal exposures, 363,099 information requests, 4,790 human confirmed nonexposures, and 38 animal confirmed nonexposures. Total encounters showed a 12.9% decrease from 2021, and human exposure cases decreased by 0.771%, while health care facility (HCF) human exposure cases increased by 0.214%. All information requests decreased by 48.4%, medication identification (Drug ID) requests decreased by 21.2%, and medical information requests showed a 76.92% decrease, although these remain twice the median number before the COVID-19 pandemic. Drug Information requests showed a 52.4% decrease, due to declining COVID-19 vaccine calls to PCs but still comprised 5.55% of all information contacts. Human exposures with less serious outcomes have decreased 1.70% per year since 2008, while those with more serious outcomes (moderate, major or death) have increased 4.41% per year since 2000.Consistent with the previous year, the top 4 substance classes most frequently involved in all human exposures were analgesics (11.5%), household cleaning substances (7.23%), antidepressants (5.61%), and cosmetics/personal care products (5.23%). Antihistamines (4.81%) replaced sedatives/hypnotics/antipsychotics as the 5th substance class. As a class, analgesic exposures increased most rapidly, by 1,514 cases/year (3.26%/year) over the past 10 years for cases with more serious outcomes.The top 5 most common exposures in children age 5 years or less were household cleaning substances (10.3%), analgesics (9.54%), cosmetics/personal care products (9.49%), dietary supplements/herbals/homeopathic (6.65%), and foreign bodies/toys/miscellaneous (6.61%). NPDS documented 3,255 human exposures resulting in death; 2,622 (80.6%) of these were judged as related (RCF of 1-Undoubtedly responsible, 2-Probably responsible, or 3-Contributory). CONCLUSIONS: These data support the continued value of PC expertise and the need for specialized medical toxicology information to manage the increasing number of more serious exposures. Unintentional and intentional exposures continue to be a significant cause of morbidity and mortality in the US. The near real-time status of NPDS represents a national public health resource to collect and monitor US exposure cases and information requests. The continuing mission of NPDS is to provide a nationwide infrastructure for surveillance for all types of exposures (e.g., foreign body, infectious, venomous, chemical agent, or commercial product), and the identification and tracking of significant public health events. NPDS is a model system for the near real-time surveillance of national and global public health.

Epidemiología y calidad asistencial de las intoxicaciones agudas en el adulto mayor de 65 años en Alicante, España / Epidemiology and quality of care of acute intoxication in people over 65 years of age in Alicante, Spain

Introducción El objetivo fue estudiar la epidemiología de las intoxicaciones agudas en el servicio de urgencias (SU) de un centro de tercer nivel y analizar el grado de cumplimiento de los indicadores de calidad (IC) en pacientes ≥65 años comparado con el resto de los adultos. Material y métodos Estudio observacional y retrospectivo, se incluyeron los casos diagnosticados de intoxicación aguda de pacientes >14 años atendidos en el SU de un hospital terciario. Se recogieron las variables demográficas, tipo de tóxicos y causa de la intoxicación, 19 IC y destino, siendo la variable de resultado el grado de cumplimiento de los IC. Resultados Se registraron 1.144 casos, 10,4% (n=119) personas ≥65 años. Hubo mayor proporción de mujeres en este grupo (72,8 vs. 60,9%; p=0,015), más intoxicación accidental (37,6 vs. 25,7% p=0,006), y menos voluntaria (35,0 vs. 49,6%; p=0,003), menos intoxicación por alcohol (5 vs. 17,8%; <0,001) y ningún caso intoxicado por drogas ilegales (p<0,001). En la mayoría de los IC tenían un alto grado de cumplimento (> 85%) en personas ≥65 años como en el resto de los adultos. De todos los IC hubo diferencias en la indicación de oxigenoterapia en el caso de intoxicación por monóxido de carbono (CO) en aquellos ≥65 años (64,2 vs. 40,9%; p=0,005). Conclusiones El perfil epidemiológico de la intoxicación en personas ≥65 años es diferente al de los más jóvenes y con un cumplimiento de los IC. Dado los resultados obtenidos no consideramos que existan diferencias en la asistencia del paciente intoxicado con respecto a su edad (AU)

Introduction The objective of this study was to examine the epidemiology of acute poisonings in the emergency department (ED) of a tertiary center and to analyze the compliance level with quality indicators (QIs) in patients 65 years and older compared rest of adults. Materials and methods This was an observational and retrospective study that included diagnosed cases of acute poisoning in patients over 14 years old treated in the ED of a tertiary hospital. Demographic variables, type of toxic substances, and cause of poisoning were collected, along with 19 QIs and patient outcomes, with the main outcome variable being the degree of compliance with the QIs. Results A total of 1144 cases were recorded, with 10.4% (n=119) being patients 65 years and older. Patients 65 years and older were more likely to be female (72.8% vs. 60.9%; p=0.015), experience more accidental poisonings (37.6% vs. 25.7%; p=0.006), and fewer intentional poisonings (35.0% vs. 49.6%; p=0.003). There were fewer cases of alcohol poisoning (5% vs. 17.8%; p<0.001), and no cases of illegal drug poisoning (p<0.001) in this age group. Most QIs showed a high degree of compliance (>85%) in both patients 65 years and older and rest of adults. However, there were differences in the indication of oxygen therapy in cases of carbon monoxide poisoning (64.2% vs. 40.9%; p=0.005). Conclusions The epidemiological profile of poisoning in patients 65 years and older differs from that of adult patients, with a similar degree of compliance with QIs. Based on the results obtained, there does not appear to be significant differences in the management of poisoned patients based on their age (AU)

Banning highly hazardous pesticides saves the lives of young people, particularly females, in low- and middle-income countries.

Pesticide self-poisoning is a public health problem mostly affecting low- and middle-income countries. In Sri Lanka, India and China suicide rates have reduced among young people, particularly females, following highly hazardous pesticides (HHP) bans. This success story requires attention to encourage more research on differential effects of HHP bans.

Demographics and Clinical Characteristics Assessment of Severe Acute Toxic Ingestions in Pediatric Patients: A Single-Center Study in Jilin Province of China.

OBJECTIVE: This study aimed to describe the demographic and clinical characteristics of severe acute toxic ingestions in children in Jilin Province and provide a reference for seeking effective measures to prevent poisoning accidents. METHODS: The clinical data of patients diagnosed with acute toxic ingestions and who presented with severe life-threatening symptoms or organ dysfunction at the Pediatric Intensive Care Unit of the First Hospital of Jilin University were retrospectively analyzed. Patients with incomplete clinical medical records, unclear toxic substance, and loss to follow-up within 6 months of discharge are excluded. We sorted out these children's demographic characteristics, types of poisoning, clinical manifestations, treatment process, and follow-up, etc. RESULTS: This study enrolled 141 cases with no significant differences in sex and region; adolescents accounted for 44.68%. The most common poisons were pesticides and insecticides for rural areas and internal medication for urban areas. With poisoning details as a grouping variable, there was no statistical difference between sex groupings (χ2 = 6.018, P = 0.198) and no difference between region groups (χ2 = 3.775, P = 0.289). However, there were statistical differences between age groups (χ2 = 28.22, P = 0.001). In this research, patients younger than 6 years are mainly unintentionally poisoned, whereas the suicide rate of the urban group (P < 0.05), adolescents (P < 0.01), and girls (P < 0.01) has increased significantly; moreover, the suicide group is more likely to take more overdose medication or pesticides and insecticides (P < 0.01). In addition, there was a statistical difference between suicide and length of intensive care unit stay (r = 0.268, P < 0.01). A total of 90.78% of the patients were successfully discharged after comprehensive treatment. Children aged younger than 12 years had good psychological and intellectual development during the follow-up period, whereas adolescents diagnosed with depression often required long-term psychological and medication intervention. CONCLUSIONS: This study identified poisoning details in different ages, regions, and sex of acute severe oral poisoning in children from Jilin Province. The results presentation of different prevention priorities should vary among children of different ages and emphasize adolescent suicide being a reality in Jilin Province. There is an urgent need for further culture-specific research in this area.

The clinico-epidemiological, diagnostic and therapeutic aspects of methanol poisoning: A five-year retrospective study, northern Iran.

INTRODUCTION: Methanol poisoning (MP) is a serious health issue that has become more prevalent in recent years and has resulted in numerous deaths. Early detection and timely treatment are critical for preventing fatalities and reducing the incidence of neurological complications. PATIENTS AND METHODS: This study was designed as a retrospective investigation with the purpose of analyzing the clinico-epidemiological, diagnostic, and therapeutic aspects of patients who were admitted to two training hospitals in northern Iran due to MP. The selection of samples for this study was based on a pre-defined checklist. Following the completion of the treatment period in the hospital, the patients were categorized into three groups based on their clinical outcome. All relevant variables for each group were recorded and reported separately, using the SciPy library in the Python programming language. RESULTS: The majority of the patients (88.12%) were male (P=0.012), the average age was 41.46, and mostly (82.18%) lived in urban regions (P=0.025). The primary clinical complaint reported was visual disorders, accounting for 75.25% of the cases, followed by nervous, gastrointestinal, respiratory, and chest pain accordingly. The average hospitalization length for the patients was 5.065 days. Out of the 101 patients, 65 (64.36%) were discharged without any complications, 17 (16.83%) were discharged with complications, and unfortunately, 19 (18.81%) were died. CONCLUSION: A decreased level of consciousness and severe metabolic acidosis are commonly associated with unfavorable outcomes in MP. The use of systemic corticosteroids as a treatment method has a significant association with reducing mortality rates.

[Exposures to fruit plants in Germany from 2010-2019 : Analysis of the Erfurt joint poison information center database]. / Expositionen mit Fruchtpflanzen in Deutschland im Zeitraum 2010­2019 : Auswertung der Datenbank des Gemeinsamen Giftinformationszentrums Erfurt (GGIZ).

BACKGROUND: Inquiries about fruit plants are a frequent reason for consultation with poison information centers, although it should be emphasized that there are no large systematic studies on toxicity based on exposure data. The aim of this work is to determine the risk of poisoning by fruit plants in Germany. METHODS: Retrospective study of data from the Erfurt Joint Poison Information Center on poisoning inquiries regarding fruit plants (2010-2019) with a detailed presentation of interim results, a tabular handout, plant photos as identification aids, and trend analyses. RESULTS: From 16,088 plant exposures with 16,700 plants, 214 different fruit plant species were identified. Forty-five fruit plant species (21%) turned out to be relevant (≥ 30 inquiries) and of these, 6 (2.8%) turned out to be highly relevant (≥ 300 inquiries). All relevant plants were assigned a defined risk category (RC): RC 0 (2; 4.4%), RC 1 (26; 57.8%), RC 2 (12; 26.7%), and RC 3 (5; 11.1%). Regarding the inquiries, 6% (459/7607) were related to RC 0; 47.9% (3645/7607) to RC 1; 39.3% to RC 2 (2986/7607); and 6.8% (517/7607) to RC 3. Of the inquiries, 69.5% (5284/7607) were related to young children (1 to < 6 years). Exposure outcomes for all age groups were asymptomatic in 82%, mild in 14.7%, moderate in 3%, and severe in 0.3%, with severe poisoning caused by seven plant species. Interventions were initiated in 66.8% (5079) of the inquiries. Inquiries were most frequently related to Taxus baccata, Ligustrum vulgare, Physalis alkekengi, Prunus laurocerasus, Convallaria majalis, Mahonia spec., Sambucus spec., Lonicera spec., Sorbus aucuparia, Thuja spec., Hedera helix, and Cotoneaster spec. DISCUSSION: Poisoning by fruit plants in Germany is rare. However, there is a great need for information and education.

A lethal cocktail - shining a light on the relationship between alcohol use and pesticide self-poisoning.

INTRODUCTION: Alcohol and pesticides are toxic substances that each cause acute and chronic harm to humans. Alcohol plays an important and complex role in pesticide self-poisoning, involving toxicological, public health, and social aspects important for research, prevention, and interventions. ALCOHOL USE DISORDER AND SOCIAL HARMS: While the evidence on alcohol co-ingestion in the context of pesticide self-poisoning is limited, it appears that alcohol use increases complications. Even fewer studies address alcohol use disorder and dependence among pesticide self-poisoning patients. The harmful use of alcohol also impacts social life, families, and communities in several ways, including pesticide self-poisoning among individuals around the alcohol user. This, however, is vastly understudied. OUTSIDE INFLUENCES: Agrochemicals and alcohol are produced by industries with financial interests, and the outcome of individual acts of pesticide self-poisoning depends on the lethality of the pesticide purchased and ingested. The promotion of acutely toxic pesticides by companies must be acknowledged within this issue. CONCLUSION: The relationship between alcohol and pesticide self-poisoning is increasingly clear, but more studies are needed to guide management. We cannot ignore that pesticide self-poisoning and harmful use of alcohol occur within the context of wider, often structural, stressors and are influenced by commercial entities.

Differences in the characteristics of people who purchase pesticides from shops for self-harm versus those who use pesticides available in the domestic environment in Sri Lanka.

OBJECTIVE: Data from South Asia indicate that for 15%-20% of suicide attempts, pesticides are purchased from shops; otherwise, pesticides are obtained from an individual's house or nearby environment. We aimed to investigate the difference between individuals who directly purchase pesticides from shops for suicide attempts and suicide deaths versus those related to accessing the pesticides from an individual's house or nearby environment. METHODS: We conducted two comparative studies in rural Sri Lanka: (1) non-fatal shop cases (n = 50) were survivors of self-poisoning with pesticides who ingested the pesticides after purchasing them from a shop; non-fatal domestic cases (n = 192) were survivors who accessed pesticides from their house or nearby environment. (2) fatal shop cases (n = 50) were individuals who died after ingesting pesticides they purchased for the act; fatal domestic cases (n = 102) were patients who died after ingesting pesticides they accessed at house or nearby environment. Logistic regression analysis was used to assess the characteristics which distinguished between the shop and domestic cases. RESULTS: Data indicate that 20.7% and 32.9% of individuals who used pesticides for suicide attempts and suicide deaths had purchased them from shops, respectively. Being a non-farmer was the main distinguishing characteristic of shop cases: adjusted odds ratios (AOR) 8.9, 95% confidence intervals (CI) 3.2-24.4 for non-fatal shop cases, and AOR 4.0, 95% CI 1.5-10.6 for fatal shop cases. Non-fatal shop cases also had higher suicide intent (AOR 3.0, CI 1.0-8.9), and ingesting an insecticide (AOR 4.8, CI 1.8-1.0-8.9) than non-fatal domestic cases. CONCLUSION: A high suicide intent of individuals who purchase pesticides for the event explains the high proportion of such fatal cases. Such high suicide intent makes the prevention implications difficult to spell out for those individuals who purchase pesticides for self-poisoning. However, our findings are valuable for clinicians to assess pesticide poisoning cases in hospitals.

Retrospective Evaluation of Poisoning Cases Followed Up in a Pediatric Intensive Care Unit-A 12-Year Experience in a Single Center.

OBJECTIVES: Poisonings constitute an important part of preventable morbidity and mortality in pediatric intensive care units (PICUs) and hospitalizations. However, information on poisoning requiring intensive care is limited. This study aimed epidemiological evaluation of poisoning cases treated in the PICU in a single center. METHODS: The records of 504 patients admitted to the PICU due to acute poisoning between 2010 and 2022 were retrospectively reviewed. Data were evaluated using descriptive methods and the χ 2 test, and statistical differences with P value <0.05 were considered significant. RESULTS: The age range of the patients ranged from 1 month to 216 months (18 years), and the rate of girls was 53.2% (n = 268), whereas the rate of boys was 46.8% (n = 236). The mean age was 4.4 ± 4.3 years for boys, 6.7 ± 5.8 years for girls, and 5.6 ± 5.3 years for all patients. It was determined that 79.6% of the cases were poisoned by accident and 20.4% by suicide. A total of 76.7% of the patients who were poisoned for suicide were girls and 23.3% were boys. The mean age of these patients was 14.3 ± 3.0 years. On the other hand, 47.1% of the children who were accidentally poisoned were girls and 52.9% were boys, and the mean age of these children was 3.4 ± 2.9 years. Although 79.9% of poisonings occurred at home, the causative agent was oral poisoning in 97.4% of the cases. Approximately two thirds (69.2%) of the cases were drug-related, whereas 30.8% were related to nondrug substances. In drug-related poisonings, central nervous system drugs (35.8%) were the most common agent, followed by analgesic/antipyretic (20.9%) agents, whereas among the nonpharmaceutical factors, insecticides (agricultural pesticides, rat poison, pesticides, etc) were the most common, followed by poisonous herbs (beetleweed, widow's weed, cannabis, etc). The mean admission time of the patients to the hospital was 6.3 ± 8.4 hours, and the mean length of stay in the intensive care unit was 1.6 ± 1.3 days. In the 12 years of our study, only 3 patients died due to poisoning, and our mortality rate was 0.5%. Four patients (0.7%) were referred to the Alcohol and Drug Addicts Treatment and Research Center. CONCLUSIONS: In this study, in which we retrospectively analyzed the profiles of poisoning cases hospitalized in the PICU for 12 years, we determined that poisonous weeds were the major factor in accidental poisonings, and suicidal poisonings were above the expected rates even at the young age group such as 8-12 years old. These results show the importance of determining the poisoning profile of the health care service area.
