The safety and efficacy of methylnaltrexone in pediatric oncology patients: A single center experience.

Introduction: Peripherally acting -opioid receptor antagonists (PAMORAs) are used in the treatment of opioid induced constipation without impacting the actions of opioid analgesics. Subcutaneous methylnaltrexone was one of the first PAMORAs approved in April 2008 for the treatment of opioid induced constipation in adult patients. The safety and effectiveness of methylnaltrexone has not been established in pediatric patients.

Outpatient clinical pharmacy practice in the face of COVID-19 at a cancer center in New York City.

Purpose: With the rapid spread of COVID-19 in New York City since early March 2020, innovative measures were needed for clinical pharmacy specialists to provide direct clinical care safely to cancer patients. Allocating the workforce was necessary to meet the surging needs of the inpatient services due to the COVID-19 outbreak, which had the potential to compromise outpatient services. We present here our approach of restructuring clinical pharmacy services and providing direct patient care in outpatient clinics during the pandemic.

Management of Patients with Acute Methotrexate Nephrotoxicity with High-Dose Leucovorin.

Background: Acute kidney injury complicating high-dose methotrexate (HDMTX) therapy increases the risk for severe mucositis, myelosuppression, and death. It is unclear whether high-dose leucovorin and supportive therapy without the use of glucarpidase can reduce toxicity from HDMTX.

Study Design: The charts of all patients at Memorial Sloan Kettering Cancer Center whose methotrexate (MTX) drug levels at 48 or 72 hours after administration were 10 times or more the toxic level were reviewed between January 2000 and December 2011.

Retrospective Analysis of Posaconazole Suspension Dosing Strategies in a Pediatric Oncology Population: Single-Center Experience.

Limited data on optimal posaconazole dosing strategies for pediatric patients exist. In this study, we found that the median initial dose in patients who achieved a posaconazole plasma concentration of 0.7 μg/mL was 22.

Voriconazole Dosing in Children Younger Than 3 Years Undergoing Cancer Chemotherapy or Hematopoietic Stem Cell Transplantation.

There are limited pediatric population pharmacokinetic data for voriconazole dosing, particularly in younger children. In a cohort of 34 patients younger than 3 years receiving voriconazole, the majority (n = 23, 68%) had a low initial serum concentration <1 mg/L. Among 23 children <2 years old, 19 (83%) had an initial trough <1 mg/L.
