Chronic pain in children and young adults occurs frequently and contributes to early disability as well as personal and familial distress. A biopsychosocial approach to evaluation and treatment is recommended. Within this approach, there is a role for pharmacologic intervention. ⋯ Drug delivery systems have evolved, and practitioners have to decide amongst not only medication classes, but also routes of delivery. Opioids are not recommended for use by non-pain specialists for the treatment of pediatric chronic pain, and even then the issues are more complex than can be addressed here. This article reviews the major medications used for pediatric chronic pain conditions.

In the US, children diagnosed with cancer are living longer, but not without consequences from the same drugs that cured their cancer. In these patients, cardiovascular disease is the leading cause of non-cancer-related morbidity and mortality. ⋯ Besides anthracyclines, newer molecularly targeted agents, such as vascular endothelial growth factor receptor and tyrosine kinase inhibitors, also have been associated with acute hypertension, cardiomyopathy, and increased risk of ischemic cardiac events and arrhythmias, and are summarized here. This review also covers other risk factors for chemotherapy-related cardiotoxicity (including both modifiable and non-modifiable factors), monitoring strategies (including both blood and imaging-based biomarkers) during and following cancer treatment, and discusses the management of cardiotoxicity (including prevention strategies such as cardioprotection by use of dexrazoxane).

Delirium is a serious and common problem in severely medically ill patients of all ages. It has been less addressed in children and adolescents. ⋯ Olanzapine, quetiapine, and risperidone are presently considered first-line drugs, usually replacing haloperidol. Other agents have shown promise, including melatonin to address the sleep disturbance characteristic of delirium, and dexmedetomidine, an α2-agonist, that may facilitate lower doses of benzodiazepines and opioids that may worsen delirium.

Nausea and vomiting of pregnancy (NVP) affects up to 85 % of all pregnancies. Effective treatment can greatly improve a woman's quality of life, reduce the risk for maternal and fetal complications, and reduce healthcare costs. Unfortunately, many women receive either no pharmacological treatment or are recommended therapies for which fetal safety and efficacy have not been established. ⋯ This combination, formulated as a 10 mg/10 mg delayed-release tablet, was approved by the US Food and Drug Administration (FDA) for the treatment of NVP in April 2013 under the brand name Diclegis(®), and has been on the Canadian market since 1979, currently under the brand name Diclectin(®). The efficacy of Diclegis(®)/Diclectin(®) has been demonstrated in several clinical trials, and, more importantly, studies on more than 200,000 women exposed to doxylamine and pyridoxine in the first trimester of pregnancy have demonstrated no increased fetal risk for congenital malformations and other adverse pregnancy outcomes. The present review aims to present the scientific evidence on the effectiveness and fetal safety of Diclegis(®)/Diclectin(®) for the treatment of NVP to justify its use as first-line treatment for NVP.

Many factors contribute to suboptimal pain management in children. Current evidence suggests that severe pain in children has significant long-lasting effects, even more so than in adults. In particular, recent evidence suggests a lack of optimal postoperative pain management in children, especially following ambulatory surgery. ⋯ Currently available treatment options are discussed with reference to the efficacy and side effects of opioid and non-opioid and regional analgesic techniques. The impact of preoperative anxiety on postoperative pain, and the efficacy of some nonpharmacological techniques such as hypnosis or distraction, are also discussed. Finally, basic organizational strategies are described, aiming to promote safer and more efficient postoperative pain management in children.
