Fundaments of Toxicology-Approach to the Poisoned Patient
ADVANCES IN CHRONIC KIDNEY DISEASE
Authors: Ornillo, Chiarra; Harbord, Nikolas
Abstract
Management of the poisoned patient begins with supportive care, assessment of organ function and dysfunction, and consideration of known or suspected poisons. The possibility of multiple ingestions should be considered with intentional exposures or suicide attempts. Enteric decontamination involves treatment to prevent the absorption of toxins from the gastrointestinal system and includes the use of activated charcoal. Poisoned patients may benefit from the use if antidotes are available, or enhanced elimination as with salicylate ion trapping during urinary alkalinization. The use of intravenous lipid therapy is of clinical benefit in poisoning from bupivacaine, amitriptyline, and bupropion. Hemodialysis is the most inexpensive, widely available, and most commonly used method of extracorporeal drug removal in the treatment of poisoning. Chelators with different chemical properties can bind toxic metals, providing an essential mechanism for detoxification, and may be used in combination with extracorporeal therapies such as DFO with HD for aluminum or iron, and DMSA or DMPS with HD to treat arsenic or mercury intoxication. The use of displacers with hemodialysis can be considered to augment clearance of protein bound toxins. (C) 2019 by the National Kidney Foundation, Inc. All rights reserved.
When to Consider Prophylactic Antimigraine Therapy in Children with Migraine
CURRENT TREATMENT OPTIONS IN NEUROLOGY
Authors: Qureshi, Mushtaq H.; Esper, Gregory J.; Bashir, Ferhad F.
Abstract
Purpose of reviewHeadache is not an uncommon complaint in children, and recognition of migraine is increasing in children and adolescents. Treatment options consist of abortive and preventive medications; however, when to start the preventive treatment is not clear in the pediatric population. This article reviews current guidelines and practices to provide a better clinical approach in the management of migraines in children and adolescents.Recent findingsCurrently, the only FDA-approved medical treatment option for preventive therapy in chronic migraine in adolescents is topiramate. However, the Childhood and Adolescent Migraine Prevention Study (CHAMP) did not endorse superiority of topiramate or amitriptyline over placebo.SummaryAt this time, there is no clear consensus on when to start preventive therapy in children and adolescents with migraines. The decision is multifactorial and should be initiated after a thorough discussion with the patient and caregiver(s) about related risks and benefits of treatment. Education regarding various modalities of treatment and ensuring compliance is essential to treatment success.
