   "content": "- Acute poisoning/intoxication is a common pediatric emergency; children are especially susceptible because of their curious, exploratory nature and tendency to put things in their mouths.\n- Three common clinical scenarios: accidental ingestion by preschool-age children (peak incidence in the 2nd year of life; about 85% of accidental poisonings affect children under 5), intentional suicide attempts by adolescents, and recreational drug use.\n- Accidental exposure accounts for the large majority of pediatric poisonings (around 97%) versus intentional attempts (around 3%) in national database reporting, though this ratio shifts toward intentional ingestion in older children and teenagers.\n- Common agents vary by setting: in high-income countries, pharmaceuticals and household products/chemicals predominate; in low/middle-income countries and some national data, kerosene, pesticides, cleaning agents, and pharmaceuticals are common, with household products (about 47%), drugs (about 22%), and agricultural pesticides (about 9%) frequently cited categories.\n- Substances that are potentially harmful even in small/single doses (\"one pill can kill\" category): alcohol, acids/alkalis, bleach, digoxin, batteries, iron, paracetamol (acetaminophen), petroleum distillates, salicylates, and tricyclic antidepressants; other lethal or potentially lethal pharmaceutical ingestions include antimalarials, beta-blockers, calcium channel blockers, camphor, antidiarrheals, and opioids.\n- Alcohol is the substance most frequently abused by children and adolescents in the US, associated with the leading causes of death and injury in this age group (motor vehicle accidents, homicides, suicides); among youth who drink, the proportion who binge drink rises from about 50% at ages 12-14 to about 72% at ages 18-20. Adult intoxication reference ranges (not established for children) are roughly 50-80 mg/dL for impaired faculties and 80-100 mg/dL for intoxication.\n- Toxic ingestion accounts for up to 32.5% of pediatric ataxia cases; agents linked to ataxia include antihistamines, alcohol, anticonvulsants (especially phenytoin and carbamazepine), barbiturates, carbon monoxide, and organic solvents - suspect ingestion whenever symptoms don't fit a clear clinical syndrome.\n- Initial management always starts with assessment and stabilization of airway, breathing, and circulation (ABCs) before proceeding to identify and quantify the specific poison; management then follows the sequence: remove the child from the poison source, provide symptomatic/supportive care, remove unabsorbed poison (GI decontamination, skin/eye irrigation), hasten elimination of absorbed poison, and give a specific antidote if one exists.\n- Substance use or withdrawal should be part of the differential diagnosis for any adolescent with chronic persistent irritability; a positive history can be hard to elicit and toxicology screening is not always helpful, so a strong index of suspicion is needed, and rare cases may represent intentional poisoning of the child.\n"

   "title": "Definition",
   "content": "Substance intoxication in children encompasses acute poisoning from ingested toxins (household products, pharmaceuticals, chemicals) and intoxication from recreational or abused substances (alcohol, marijuana, cocaine, phencyclidine, methamphetamine, and others). Exposure can occur through direct ingestion, dermal/ophthalmologic/inhalational routes, or passively - transplacentally, through breast milk, or by being in an environment where drugs are used or manufactured, any of which can produce severe intoxication.\n"

  {
   "title": "Epidemiology",
   "content": "Acute poisoning is a common and challenging pediatric emergency and an important cause of morbidity and mortality in children, particularly in developing countries. Children are susceptible because of their curious, exploratory nature and propensity to put things in their mouths. The large majority of poisonings in children under 5 years are accidental, while poisonings in older children and teenagers are largely intentional. National database reporting suggests accidental exposure accounts for roughly 97% of cases versus about 3% intentional, with peak incidence of accidental ingestion in the second year of life and about 85% of accidental poisonings occurring in children under 5. Common agents differ by setting: in high-income countries, pharmaceuticals and household products/chemicals predominate; in other settings, kerosene, pesticides, cleaning agents, and pharmaceuticals are commonly involved. One national dataset breaks down poisoning causes as household products (about 47%, including kerosene, pyrethroids, rodenticides, mercury, phenyl, detergents, and corrosives), drugs (about 22%, including benzodiazepines, anticonvulsants, thyroid hormone, iron, and paracetamol), agricultural pesticides (about 9%), industrial chemicals (about 8%), bites and stings (about 3%), and plants/plant derivatives (about 1.5%). Alcohol is the substance most frequently abused by children and adolescents in the United States, and its use is linked to the leading causes of death and serious injury in this age group - motor vehicle accidents, homicides, and suicides. Among youth who drink, the proportion who binge drink is higher than among adult drinkers, rising from about 50% at ages 12-14 to about 72% at ages 18-20.\n"

  {
   "title": "Etiology",
   "content": "The cause of childhood poisoning varies widely, but the most frequent ingestions involve readily accessible household products - cosmetics, hair products, cleaning substances, and analgesics. The most lethal or potentially lethal poisonings, however, are most often related to pharmaceuticals: antimalarials, beta-blockers, calcium channel blockers, camphor, antidiarrheals, salicylates, opioids, and tricyclic antidepressants. Other substances potentially harmful to children even in small quantities include alcohol, acids and alkalis, bleach, digoxin, batteries, iron, paracetamol (acetaminophen), and petroleum distillates. Common sources of alcohol poisoning include alcoholic beverages, tinctures, cosmetics, mouthwashes, food extracts (vanilla, almond), rubbing alcohol, hand sanitizers, and powdered alcohol; concomitant exposure to other depressant drugs increases the severity of intoxication.\n"

  {
   "title": "Clinical Features",
   "content": "Symptoms of poisoning are often nonspecific, and ingestion should be suspected whenever a presentation does not fit neatly into a clear clinical syndrome. Physical examination findings can offer clues to the ingested substance and the seriousness of the ingestion - for example, pallor from hemolysis or cyanosis from methemoglobinemia. Toxic ingestion is a major cause of pediatric ataxia, accounting for up to 32.5% of cases; agents associated with ataxia include antihistamines, alcohol, anticonvulsants (especially phenytoin and carbamazepine), piperazine, barbiturates, carbon monoxide, organic solvents, and bromides. When toxic ingestion is being considered, evaluation should also include screening for metabolic derangements such as hypoglycemia, hyponatremia, and hyperammonemia, which can mimic or accompany intoxication. Substance use or withdrawal should be considered in the differential diagnosis of any adolescent with chronic persistent irritability. A positive history of ingestion or substance use can be difficult to elicit, and toxicologic screening is not always helpful, so a strong index of suspicion is required; in rare instances, intentional poisoning by a caregiver may be the underlying cause of a child's presentation.\n"

  {
   "title": "Diagnostics",
   "content": "Evaluation begins with a comprehensive history obtained from witnesses, family, and friends regarding the nature of the substance ingested, timing, and amount, followed by general physical and neurological examination once the child is stabilized. Laboratory and diagnostic studies are used to identify and quantify the poison and to detect associated metabolic derangements.\n"

  {
   "title": "Treatment",
   "content": "Initial management always addresses airway, breathing, and circulation (the ABCs) before proceeding to detailed evaluation and identification of the ingested substance. The general principles of poisoning management are: removal of the child from the source of poison; initial resuscitation and stabilization; symptomatic and supportive care; removal of unabsorbed poison (from the gastrointestinal tract, or from skin, eyes, and other body surfaces as relevant); measures to hasten elimination of absorbed poison; and administration of a specific antidote when one is available. As with any high-risk adolescent behavior, prevention is more effective than later intervention, and pediatricians should ask every adolescent directly about alcohol use as a routine part of care.\n"

   "content": "Poisoning is an important cause of pediatric morbidity and mortality, particularly in developing countries. Substance use in adolescents is specifically linked to the leading causes of death and serious injury in this age group - motor vehicle accidents, homicides, and suicides - underscoring that the risks of intoxication extend well beyond the acute toxic effects of the substance itself.\n"

   "title": "Initial Approach to the Child with Suspected Poisoning or Intoxication",
   "content": "Address airway, breathing, and circulation first, regardless of the substance suspected, before pursuing identification of the poison. Take a comprehensive history from witnesses, family, and friends covering the substance, timing, and estimated amount, and examine for clues such as pallor (hemolysis) or cyanosis (methemoglobinemia) that can point toward a specific toxidrome. Suspect toxic ingestion whenever a child's presentation - especially new-onset ataxia, altered mental status, or symptoms that don't fit a clear clinical syndrome - lacks another obvious explanation, and screen concurrently for hypoglycemia, hyponatremia, and hyperammonemia, which can mimic or compound the picture. Remember that accidental ingestion peaks in the second year of life and affects mostly children under 5, while intentional ingestion becomes more relevant in older children and adolescents - adjust your index of suspicion for self-harm accordingly, and consider intentional poisoning by a caregiver in atypical or recurrent presentations.\n"

   "title": "Managing the Poisoned or Intoxicated Child",
   "content": "Follow the standard sequence: remove the child from ongoing exposure, resuscitate and stabilize, provide symptomatic and supportive care, decontaminate (GI, skin, eye, or other exposed surfaces as appropriate), consider measures to hasten elimination of absorbed poison, and give a specific antidote where one exists. Treat any ingestion of a \"small-dose-lethal\" agent - alcohol, acids/alkalis, bleach, digoxin, a button battery, iron, acetaminophen, a petroleum distillate, salicylates, or a tricyclic antidepressant - as high-risk regardless of how well the child appears initially, given the potential for delayed or rapid deterioration. Ask every adolescent directly about alcohol and substance use as a routine part of care, since prevention is more effective than intervention after the fact, and keep substance use or withdrawal on the differential for any adolescent with unexplained chronic irritability, since history and toxicology screening are not always reliable enough to rule it out on their own.\n"
