Drug-induced liver injury (DILI) is a rare adverse drug reaction (ADR) in pediatric patients and limited reports exist examining ampicillin-sulbactam-induced liver injury. This report summarizes a 12-year-old male who received ampicillin-sulbactam and subsequently developed liver injury characterized by elevated serum aminotransferases and bilirubin. Ampicillin-sulbactam was subsequently discontinued and the patient's liver function tests (LFTs) rapidly improved.

What Is Known And Objective: Reports of cidofovir dosing with extracorporeal membrane oxygenation (ECMO) support are limited. This case series describes our clinical experience and provides a literature review regarding cidofovir dosing in paediatric patients requiring ECMO support.

Case Summary: Three patients with adenovirus-associated acute respiratory distress syndrome (ARDS) were treated with cidofovir while requiring ECMO support.

Background: There is debate whether cytomegalovirus immunoglobulin (CMV-Ig) is also needed for CMV prevention in heart transplant recipients in the era of good anti-viral drugs.

Methods: We conducted a cost-savings quality initiative on CMV-Ig eventually leading to discontinuation of routine use of CMV-Ig for CMV prevention. Subsequently, a retrospective cohort study was conducted, comparing patients in cohort I (CMV-Ig plus anti-viral drugs, 2013-2015) to cohort II (anti-virals alone, 2015-2017).

Introduction: The management of gram-positive infections has been complicated in recent years by the emergence of antimicrobial resistance, leaving fewer options for therapy. Daptomycin is a lipopeptide antibiotic used for the systemic treatment of gram-positive infections. It has a distinct mechanism of action and a favorable side effect profile, and it requires once/day dosing.

Antimicrobial stewardship (AS) programs are effective in improving clinical outcomes associated with antimicrobial therapies while improving patient safety by reducing adverse events and development of bacterial resistance. Understanding the basic principles of AS is essential to the successful development and implementation of AS strategies. Identifying and developing strategies to address barriers and challenges to AS can facilitate the establishment of financial, administrative, and organizational support, and agreement and participation by individual prescribers.

Background: The emergence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) has complicated the conventional management of osteomyelitis. While oral clindamycin is commonly used to treat acute CA-MRSA osteomyelitis, the emergence of inducible clindamycin resistance among CA-MRSA isolates has made alternative therapy necessary. The excellent oral bioavailability, susceptibility profile, favorable palatability, and low cost of trimethoprim-sulfamethoxazole (TMP-SMX) make this drug an attractive option for treating osteomyelitis, yet its clinical efficacy for osteomyelitis has not been established.

Objectives: Adverse drug events (ADEs) occur more frequently in pediatric patients than adults. ADEs frequently cause serious harm to children and increase the cost of care. The purpose of this study was to decrease ADEs by targeting the entire medication-delivery system for all high-risk medications.
