Evaluation of several clinical scoring tools in organophosphate poisoned patients.
The aim of this study was to evaluate the Acute Physiology and Chronic Health Evaluation (APACHE) II, III and Simplified Acute Physiology Score II (SAPS II) as predictors of severity of organophosphate poisoning (OPP). ⋯ The APACHE II, III and SAPS II clinical scoring tools seem to predict the severity of organophosphate poisoning, and may have prognostic value.

Practice GuidelineAcetaminophen poisoning: an evidence-based consensus guideline for out-of-hospital management.
The objective of this guideline is to assist poison center personnel in the appropriate out-of-hospital triage and initial management of patients with suspected ingestions of acetaminophen. An evidence-based expert consensus process was used to create this guideline. This guideline applies to ingestion of acetaminophen alone and is based on an assessment of current scientific and clinical information. ⋯ In patients with conditions purported to increase susceptibility to acetaminophen toxicity (alcoholism, isoniazid use, prolonged fasting), the dose of acetaminophen considered as RSTI should be greater than 4 g or 100 mg/kg (whichever is less) per day (Grade D). 3) Gastrointestinal decontamination is not needed (Grade D). Other recommendations: 1) The out-of-hospital management of extended-release acetaminophen or multi-drug combination products containing acetaminophen is the same as an ingestion of acetaminophen alone (Grade D). However, the effects of other drugs might require referral to an emergency department in accordance with the poison center's normal triage criteria. 2) The use of cimetidine as an antidote is not recommended (Grade A).

Case ReportsThe role of calcium oxalate crystal deposition in cerebral vessels during ethylene glycol poisoning.
Ethylene glycol (EG) poisoning can lead to serious morbidity or death, which occurs following conversion of ethylene glycol to toxic metabolites. These metabolites affect multiple organ/systems leading to metabolic acidosis, cardiopulmonary depression, acute renal failure and central nervous system deficits. ⋯ We describe a case of fatal EG poisoning in which the development of rapid cerebral edema was documented by CT scan and was accompanied by definitive evidence of birefringent crystals within walls of CNS blood vessels, with associated inflammation and edema. This case and others in the literature suggest that cerebral edema, and perhaps injury to other organs, could result from oxalate crystal deposition in small blood vessels in the brain and other organs.

Comparative StudyA comparison of vasopressin and glucagon in beta-blocker induced toxicity.
We compared the efficacy of vasopressin and glucagon in a porcine model of beta-blocker toxicity. Our primary outcome was survival over 4 hours. ⋯ In this beta-blocker toxicity model, there were no differences in the survival curves between vasopressin- and glucagon-treated pigs during a 4-hour analysis period. No overall differences were noted in MAP, systolic BP, CO, HR, pH, or glucose levels, although vasopressin treatment yielded higher MAP and systolic BP early in resuscitation.

Analysis of 8000 hospital admissions for acute poisoning in a rural area of Sri Lanka.
Acute poisoning, especially deliberate self-poisoning with agricultural pesticides, is an emerging global public health problem, but reliable incidence estimates are lacking. Only a few previous studies have assessed the impact of regulatory or other preventive measures. ⋯ Regulatory control of highly toxic pesticides provides important health benefits, especially in terms of lower number of deaths from self-poisoning. However, despite the positive effect of these bans, many deaths from pesticide self-poisoning still occur after ingestion of agricultural pesticides classified as only moderately poisonous.
