Benzodiazepine resistant alcohol withdrawal: What is the clinician's preferred definition?

Objectives: Although alcohol withdrawal is common, the recognition of benzodiazepine-resistant alcohol withdrawal is a relatively new concept. To provide a framework for both literature review and future research, we assessed clinicians' personal definition of resistant alcohol withdrawal.

Method: We developed a cross-sectional web-based survey.

Guidelines for reporting case studies and series on drug-induced QT interval prolongation and its complications following acute overdose.

The assessment and management of patients with QT interval prolongation in poisoning requires an appropriate method of measuring and adjusting the QT interval for the heart rate (HR) in order to decide if the patient is at risk of life-threatening dysrhythmias, notably torsade de pointes (TdP). As the Clinical Toxicology Collaborative (CTC) workgroup reviewed the published literature on drug-induced QT interval prolongation in poisoning, it became obvious that many publications were missing essential data that were necessary to thoroughly assess and compare the evidence. The aim of this guidance document is to identify essential and ideal criteria required when reporting a case of drug-induced QT interval prolongation and/or TdP in poisoning.

Extracorporeal treatments in poisonings from four non-traditionally dialysed toxins (acetaminophen, digoxin, opioids and tricyclic antidepressants): A combined single-centre and national study.

The use of extracorporeal treatments (ECTRs) for poisonings with four non-traditionally dialysed toxins (NTDTs) is increasing in the United States. This study evaluated whether ECTRs are prescribed for toxin removal or the treatment of other medical illnesses or complications. We performed a 2-Phase retrospective analysis evaluating the main indication for ECTRs in patients with poisoning from a NTDT (defined for this study as acetaminophen, opioids, tricyclic antidepressants (TCAs) or digoxin) and ECTR.

Availability and cost of extracorporeal treatments for poisonings and other emergency indications: a worldwide survey.

Background: Extracorporeal treatments (ECTRs) are used for different conditions, including replacement of organ function and poisoning. Current recommendations for ECTRs in various poisonings suggest that intermittent haemodialysis (IHD) is the most efficient technique. However, the practicality of these recommendations is poorly defined in view of limited information on availability and cost worldwide.

Phenytoin overdose treated with hemodialysis using a high cut-off dialyzer.

We describe the case of a 52-year-old man who presented after having ingested an unknown quantity of phenytoin. Peak phenytoin concentration was 51.2 mg/L (therapeutic range 10-20 mg/L).

Why are we Still Dialyzing Overdoses to Tricyclic Antidepressants? A subanalysis of the NPDS database.

A recent analysis of the American Association of Poison Control Centers database, showed that poisonings from toxins not usually considered amenable to extracorporeal purification ("non-classic toxins" such as ethanol and tricyclic antidepressants) continue to be reported. This publication investigates factors that may explain these findings. Our results suggest that: 1) the relatively high absolute number of ECTR performed for non-classic toxins may simply reflect the large number of exposures to these toxins, 2) poisoning from another toxin may have been the reason for ECTR initiation in some exposures to non-classic toxins, 3) poisoning from non-classic toxins may receive ECTR for purposes other than toxin removal, and 4) the decisional threshold to initiate ECTR may be lower for non-classic toxins because of heightened toxicity.

Extracorporeal treatments in a dapsone overdose: a case report.

Introduction: Intentional dapsone intoxication can be life-threatening. There is limited data on the clinical effect of extracorporeal treatments (ECTRs) on dapsone elimination. We describe a case of severe dapsone toxicity treated with different ECTRs.
