Epidemiology of poisoning
Accidental poisoning is most common in children, but deliberate self-harm becomes predominant in teenagers and early adulthood. The epidemiology of poisoning can be studied using mortality data, hospital admission rates and enquiries to poisons information services. Effective strategies for preventing suicide and reducing the risk of accidental poisoning require an understanding of the epidemiology of poisoning. (Source: Medicine)

Drug misuse
While the misuse of traditional drugs remains common, the emergence of new psychoactive substances (NPS) has changed the landscape of drug misuse in recent years. Although hundreds of NPS have been identified, opioids, including new synthetic examples, still dominate mortality. The exact substances causing toxicity are often unknown on presentation, and multiple exposures are commonly involved. Management is therefore based on a recognition of the drug group(s) involved by identifying the clinical toxidrome. (Source: Medicine)

Poisoning by metals
Lead can be absorbed after inhalation or ingestion and is toxic to most organ systems. Management involves avoidance of exposure and, in more severe cases, chelation therapy with either sodium calcium edetate or dimercaptosuccinic acid. Iron poisoning causes metabolic effects in proportion to the concentrations of free iron, although individual responses vary. Toxicity is therefore related to the dose ingested. Iron concentrations can rise and fall, making plasma concentrations difficult to interpret in acute poisoning. (Source: Medicine)

Poisoning by carbon monoxide
Accidental carbon monoxide (CO) poisoning causes 100 hospital admissions and 7 deaths per million UK population. Toxicity occurs mainly through the formation of carboxyhaemoglobin (COHb), causing ischaemia of vital organs. Features are non-specific and include headache, gastrointestinal upset, dizziness, weakness, convulsions, coma, chest pain and dyspnoea. Neuropsychiatric features can appear up to 40  days after the initial exposure. The diagnosis can be missed unless a history of exposure to sources of CO is elicited or a CO alarm triggered.

Poisoning by household products
Exposures to household products are common. Most of these exposures are accidental, causing minimal symptoms. Serious toxicity is possible if large amounts or high concentrations of products are involved. (Source: Medicine)

Does testosterone underly the interplay between male traits and territorial behavior in neotropical poison frogs?
Horm Behav. 2024 Apr 26;162:105547. doi: 10.1016/j.yhbeh.2024.105547. Online ahead of print.ABSTRACTThe ability of individual animals to defend a territory as well as various phenotypic and behavioral traits may be targets of sexual selection used by males to evaluate their competitors or by females to choose males. A frequent question in animal behavior is whether male traits and characteristics of their territory are correlated and what are the mechanisms that may mediate such associations when they exist. Because hormones link phenotype to behavior, by studying the role of testosterone in territoriality one may come clo...

Sublingual administration of atropine eye drops for treating organophosphorus poisoning
Key Clinical MessageAn 89-year-old patient with fenitrothion toxicity received sublingual atropine eye drops, reducing the intravenous atropine requirement. This alternative method enabled rapid rehabilitation, and he walked unaided, leading to discharge. (Source: Clinical Case Reports)

Principles of management of the poisoned patient
One of the fundamental complications within toxicology is that patients  may not know or disclose what they have been poisoned with. Consequently, a sound and considered general approach to identify potential harms and plan clinical management is necessary. This chapter aims to guide the reader through the initial approach and general principles to consider when managi ng a poisoned patient. (Source: Medicine)

Poisoning by paracetamol
Paracetamol overdose is common. If left untreated, liver and/or renal failure can develop. Administration of the antidote, acetylcysteine, within 8 –10 hours of overdose minimizes or prevents liver damage. After overdose, the tests used to identify that patients are at risk of liver injury are well established but have limitations. Once liver injury has occurred, important prognostic factors are the presence of hepatic encephalopathy, the int ernational normalized ratio, acid–base status and renal function. (Source: Medicine)

Metabolic complications of poisoning
Poisoning caused by a large range of drugs and chemicals can induce metabolic complications via many different mechanisms. Some metabolic complications are life-threatening but all require careful assessment, appropriate monitoring and consideration of treatment. Prompt diagnosis and management reduce morbidity and mortality. Treatment may be targeted to the specific poisoning, and can be time-critical, or can follow approaches similar to those of general and acute medicine. This review introduces metabolic complications associated with sodium, potassium, metabolic acidosis, rhabdomyolysis and methaemoglobinaemia. (Source: Medicine)
