Data on pediatric antibiotic prescribing and utilization practices at urgent care centers (UCC) remain limited. In this study, an electronic medical record-based review of UCC encounters for respiratory tract infections (RTI) of patients belonging to one mid-sized pediatric practice was performed. Antibiotic prescribing and guideline adherence were compared between UCCs that were staffed exclusively by pediatric-trained providers to those staffed otherwise. Of a total of 457 RTI visits, 330 (72%) occurred at the pediatric UCC. Across all bacterial RTIs, 82% of encounters at the pediatric UCC were guideline-adherent versus 59% at nonpediatric UCCs ( P < .001). At nonpediatric UCCs, pharyngitis was the most common RTI encounter diagnosis (40%), and full streptococcal management guideline adherence was 41%. While 93% of RTI-UCC encounters for <2 years were at pediatric UCCs, the majority of children >10 presented to nonpediatric UCCs. RTI guideline education to UCCs should be a focus of ambulatory stewardship efforts.

Objective: Antibiotics are the most common class of medication prescribed in pediatrics, with the majority of prescriptions occurring in the outpatient setting. Our objective was to evaluate the accuracy of antibiotic dose, frequency, and formulation prescribed for urinary tract infections (UTIs) in the pediatric ambulatory care setting., Methods: This was a retrospective review of electronic medical records conducted at 2 suburban pediatric practices in a mid-sized metropolitan region. Encounter-related prescriptions were identified using UTI-associated International Classification of Diseases, 10th Revision codes. Patients aged 2 months through 18 years were included if they had been prescribed an oral antibiotic for the treatment of UTI. Antibiotic dose, frequency, and formulation were considered accurate if consistent with clinical guidelines and tertiary dosing references., Results: Nearly 1 in 4 prescriptions had dosing inaccuracies. The proportion of errors was highest with amoxicillin-clavulanate (75%; 9/12) and amoxicillin (52%; 33/64). The most common reasons for dosing incorrectly were "low dose" or "unnecessarily high dose." Additionally, 55% of the included prescriptions were for oral suspensions, and 1 in 4 of these were dosed incorrectly., Conclusions: Inaccuracies in antibiotic prescribing for pediatric UTI are common, including for frequently prescribed agents and oral formulations. To address these missed opportunities for stewardship in the outpatient setting, key educational sessions with providers should include reviewing optimal antibiotic dosing for uropathogens and highlighting common errors when oral suspensions are prescribed., Competing Interests: Disclosures.

An infant presented to the emergency department with sudden onset of rapidly progressing erythematous macules and distal oedema. The rash was striking in appearance, covering most of the body, which raised concern for pressing infectious (eg, meningococcaemia) and other serious aetiologies. Nevertheless, the infant remained playful and was overall stable and posed a diagnostic and management dilemma. After an extensive workup and multispecialty consultations, the patient was eventually diagnosed with acute haemorrhagic oedema of infancy, a benign leucocytoclastic vasculitis. The patient received no treatment and resolution of the rash occurred within 7 days of onset. Recognition of this condition and its benign nature can spare patients from an extensive workup and reduce anxiety for both family members and healthcare providers., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

Pediatric antibiotic prescriptions originate from an increasingly broad range of ambulatory settings. In this retrospective study, pharyngitis, otitis media, sinusitis, pneumonia, and upper respiratory infection cases, at 11 primary care offices, 2 independent urgent care centers (UCCs), and a pediatric emergency department in Western New York, were analyzed relative to medical society practice guidelines and antibiotic utilization. Of 2358 eligible visits across all sites, 25% were for study diagnoses, with 38% at UCC ( P < .01). Across all sites, 26% of pharyngitis cases given antibiotics did not have diagnostic evidence of bacterial infection. At primary care offices and UCCs, guideline recommended first-line agents for pharyngitis and otitis media were used in only 58% and 63% of treated cases, respectively. Overall, an estimated 9855 to 12 045 avoidable antibiotic and 8030 non-guideline antibiotic courses annually are represented by the 14 sites studied. These and other study findings highlight numerous opportunities for outpatient pediatric antibiotic stewardship.

Perinatal hypoxia-ischemia remains a significant cause of neonatal mortality and neurodevelopmental disability. Numerous lines of evidence indicate that cerebral ischemic insults disrupt normal respiratory activity in mitochondria. Carnitine (3-hydroxy-4-N-trimethylammonium-butyrate) has an essential role in fatty acid transport in the mitochondrion and in modulating potentially toxic acyl-CoA levels in the mitochondrial matrix. There are no naturally occurring esterases available to reduce the accumulation of acyl-CoA but this process can be overcome by exogenous carnitine. We used a newborn rat model of perinatal hypoxia-ischemia to test the hypothesis that treatment with l-carnitine would reduce the neuropathologic injury resulting from hypoxia-ischemia in the developing brain. We found that treatment with l-carnitine during hypoxia-ischemia reduces neurologic injury in the immature rat after both a 7- and 28-d recovery period. We saw no neuroprotective effect when l-carnitine was administered after hypoxia-ischemia. Treatment with d-carnitine resulted in an increase in mortality during hypoxia-ischemia. Carnitine is easy to administer, has low toxicity, and is routinely used in neonates as well as children with epilepsy, cardiomyopathy, and inborn errors of metabolism. l-Carnitine merits further investigation as a treatment modality for the asphyxiated newborn or as prophylaxis for the at-risk fetus or newborn.
