Severe hypomagnesemia with secondary hypocalcaemia (HSH) presenting as recurrent self terminating Torsades de pointes

IHJ Cardiovascular Case Reports, 2020
Torsades de Pointes (TdP) is a potentially fatal cardiac arrhythmia, defined as the combination of polymorphic ventricular tachycardia with prolonged QT-interval. Hypomagnesemia of any cause can predispose to TdP.

An open‐label, single‐arm, dose‐escalating concentration–QT study to investigate the cardiac effects and safety of paroxetine in healthy adults

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Paroxetine is a selective serotonin reuptake inhibitor (SSRI), approved for treatment of major depressive disorder and anxiety disorders. Some SSRIs are known to prolong the QT interval; however, clinical evidence to establish a lack of association between paroxetine and corrected QT interval (QTc) prolongation is limited. Therefore, this

Retrospective, Multicenter Study of Lacosamide to Treat Neonatal Seizures

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Objective Most antiseizure medications (ASMs) are prescribed off label for neonates. Lacosamide's efficacy in infants and availability in intravenous formulation suggest potential utility for neonates. We evaluated the safety and efficacy of lacosamide for neonatal seizures. Methods This 10‐center, retrospective study of neonates with seizures

Major Adverse Cardiac Events with Ondansetron: A Systematic Review

Clinical Pharmacology &Therapeutics, EarlyView.
Evidence base: 170 randomized trials, 23,421 adults, predominantly single‐dose IV ondansetron, mean follow‐up 20 days. Observed outcomes: Major adverse cardiac events were rare, no ventricular arrhythmias or torsades de pointes observed. Conclusion: Ondansetron was not associated with increased mortality or serious cardiac arrhythmias in adult ...

Rare but relevant: Ibogaine and cardiovascular complications—prolonged QT interval and ventricular arrhythmias

Addiction, EarlyView.
Abstract Revived interest in psychedelic‐assisted therapies has also renewed focus on ibogaine, a psychoactive alkaloid, for its notable anti‐addictive potential. Evidence from observational, open‐label, and limited randomized placebo‐controlled trials indicates that ibogaine and its metabolite noribogaine reduce craving and withdrawal symptoms in ...
