This document summarizes five toxic tips and traps in treating poisoned patients:
1) Monitor ECG for signs of toxicity like QRS over 100ms, R' over 3mm, and QT interval over 450ms.
2) Give insulin early in high doses (1 unit/kg bolus and 0.5 unit/kg/h infusion) along with 50% glucose to treat overdoses.
3) Treat acidosis with sodium bicarbonate (1-2 mmol/kg bolus then hyperventilate to pH 7.5-7.55) to reverse its effects.
4) Consider intravenous lipid emulsion therapy with Intralipid (1.5 mL/
Tox-Dogmalysis is a talk about evidence in Toxicology. It’s been said that 50% of what we learn is incorrect; we just don’t know which 50%.
As the complexity of medicine increases, it is of the utmost importance for clinicians to be skeptical of old data and new data alike. Many in the FOAM community have made huge strides in busting myths that have persisted over time. However, sometimes we may declare myths busted too prematurely based on incomplete or misunderstood data.
This talk will explore three topics in toxicology for which the perceived myths may actually be true, or at least not completely busted.
Charles Feldman is Professor of Pulmonology and Chief Physician at Charlotte Maxeke Johannesburg Academic Hospital. In this talk given at an ICN Victoria meeting last year, he discusses the alphabet soup that represent pneumonia phenotypes and clarifies what it's all about. His unique perspective on the history behind this incredible relevant topic is well worth hearing and hopefully clarifies some misconceptions.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

PubMed PMID: 17881416. BACKGROUND: Although QT prolongation is associated with increased risk of torsade de pointes (TdP), the precise relationship is not well defined.AIM: To evaluate the performance of a QT nomogram in assessing the risk of TdP from QT-RR combinations.DESIGN: Systematic review.METHODS: We systematically searched MEDLINE/EMBASE for cases of drug-induced TdP. Controls were patients taking non-cardiotoxic drugs in overdose. Inclusion criteria were definite TdP, normal ECG before or after the event, association with a drug/toxin and QT-RR measurements available. The upper bound of a QT-RR cloud diagram developed from human preclinical studies was converted into a QT nomogram [QT vs. heart rate (HR)]. QT-HR combinations for TdP cases and controls were plotted with the QT nomogram, and curves corresponding to a QTc = 440 ms and QTc = 500 ms for comparison (Bazett's correction).RESULTS: We identified 129 cases of TdP. TdP cases occurred at lower HR values with longer QT intervals, with most cases occurring at HR 30-90 bpm. Controls were more evenly distributed, with HR 40-160 bpm. The sensitivity and specificity of the QT nomogram were 96.9% (95%CI 93.9-99.9) and 98.7% (95%CI 96.8-100), respectively. For BazettQTc = 440 ms, sensitivity and specificity were 98.5% (95%CI 96.3-100) and 66.7% (95%CI 58.6-74.7), respectively, whereas for BazettQTc =500 ms they were 93.8% (95%CI 89.6-98.0) and 97.2% (95%CI 94.3-100), respectively.DISCUSSION: The QT nomogram is a clinically relevant risk assessment tool that accurately predicts arrhythmogenic risk for drug-induced QT prolongation. Further prospective evaluation of the nomogram is needed.
