Background Penicillin allergy is the most common antibiotic allergy, yet most children labeled as allergic tolerate penicillin. The impact of inaccurate penicillin allergy labels (PALs) on pediatric outpatients is unknown. The objective of this study was to compare outcomes between children with and without a PAL after treatment for outpatient respiratory tract infections (RTI). Methods A retrospective, longitudinal birth cohort study was performed in children who received care in 90 pediatric primary care practices in Philadelphia and Houston metropolitan areas. Prescribing and clinical outcomes of children with a PAL at the time of an RTI were compared to non-allergic children, adjusting for potential confounders. Results Antibiotics were prescribed for 663,473 non-recurrent RTIs among 200,977 children. Children with a PAL (5% of cohort) were more likely than non-allergic children to receive broad-spectrum antibiotics (adjusted relative risk (aRR) 3.24, 95% CI 3.22-3.26) and second-line antibiotics (aRR 4.87, 95% CI 4.83, 4.89). Compared to non-allergic children receiving first-line antibiotics, children with a PAL were more likely to return with adverse drug events (aRR 1.28, 95% CI 1.18–1.39). There was no difference in treatment failure between groups (aRR 0.95, 95% CI 0.90–1.00). Conclusions PALs lead to higher rates of broad-spectrum and second-line antibiotic prescribing in children treated for RTIs in primary care and contribute to unnecessary healthcare utilization through increased adverse events. Given the frequency of PALs, efforts to prevent inappropriate penicillin allergy labeling and promote de-labeling of existing inaccurate allergy labels may improve care of children treated for common bacterial infections.

Background Suppurative intracranial complications of sinusitis are rare events in children and can lead to harmful neurologic sequelae and significant morbidity. We sought to review the presentation and management of patients admitted at our hospital with these conditions. Methods This was a retrospective study of pediatric patients admitted to a quaternary children's hospital from 2007 to 2019 for operative management of sinusitis with intracranial extension. Clinical characteristics, including surgical and microbiological data, were collected and analyzed. Results Fifty-four patients were included; the median age was 11.0 years, and there was a male predominance. Eighty-nine percent of patients had prior healthcare visits for the current episode of sinusitis; 46% of patients had an abnormal neurologic exam on admission. Epidural abscess and subdural empyema were the most common complications, and subdural empyema was associated with repeat surgical intervention. The dominant pathogens were Streptococcus anginosus group organisms (74%). The majority of patients completed treatment parenterally, with a median duration of therapy of 35 days. Neurological sequelae, including epilepsy or ongoing focal deficits, occurred in 22% of patients. History of seizure or an abnormal neurological exam at admission were associated with neurological sequelae. Conclusions Clinicians should consider intracranial complications of sinusitis in patients with symptoms of sinusitis for >1 week. Patients should undergo urgent neuroimaging, as neurosurgical intervention is essential for these patients. Subdural empyema was associated with repeat neurosurgical intervention. Neurological sequelae occurred in 22% of patients, and new onset seizure or an abnormal neurological exam at admission were associated with neurological sequelae. [ABSTRACT FROM AUTHOR]

Objective: Spinal epidural abscesses (SEAs) are rare infections in children but can lead to significant neurological sequelae. The authors sought to describe the presentation, management, and outcomes of children with these infections at their institution., Methods: This was a retrospective study of pediatric patients admitted with SEA to a quaternary children's hospital between 2013 and 2023. Clinical characteristics including laboratory, surgical, and antimicrobial data were collected and analyzed., Results: Fourteen patients (median age 3.7 years) had SEAs. Thirteen (93%) patients developed the infection in the outpatient setting, and of these 10 (77%) were evaluated by a medical provider prior to the encounter when the diagnosis was made. The most common causative pathogen was Staphylococcus aureus. Thirteen (93%) of 14 patients underwent a surgical procedure, and patients were treated with antibiotics for a median of 38 days. Eleven (79%) of 14 patients received enteral antibiotics for part of their treatment course. All patients recovered with no neurological sequelae., Conclusions: SEAs are rare infections, but good outcomes can be obtained with prompt antimicrobial and surgical management. Enteral antibiotics should be considered as part of therapy. Larger multicenter studies are needed to determine the optimal antibiotic duration and route, and which patients should undergo neurosurgical intervention versus interventional radiology drainage or medical management alone.
