Changes in the epidemiology of pediatric sinogenic and otogenic intracranial infections during the COVID-19 pandemic: a single-institution study
Bibliographic record
Abstract
OBJECTIVE: Focal intracranial infections (epidural abscesses, subdural empyemas, and intraparenchymal abscesses) are uncommon complications of sinusitis and otitis media but can be associated with significant morbidity. Treatment typically requires neurosurgical and otolaryngological interventions in combination with antibiotic treatment. Historically, children have presented to the authors' pediatric referral center with sinusitis- or otitis media-related intracranial infections in low numbers. However, since the onset of the COVID-19 pandemic, the incidence of intracranial pyogenic complications has increased at this center. The objective of this study was to compare the epidemiology, severity, microbial causes, and management of pediatric sinusitis- and otitis-related intracranial infections in the periods before and during the COVID-19 pandemic. METHODS: All patients 21 years of age or younger who presented with an intracranial infection in the setting of sinusitis or otitis media and who underwent neurosurgical treatment at Connecticut Children's from January 2012 to December 2022 were retrospectively reviewed. Demographic, clinical, laboratory, and radiological data were systematically collated, and variables before and during COVID-19 were compared statistically. RESULTS: Overall, 18 patients were treated for sinusitis-related (n = 16) or otitis media-related (n = 2) intracranial infections during the study period. Ten patients (56%) presented from January 2012 to February 2020, none from March 2020 to June 2021, and 8 (44%) from July 2021 to December 2022. There were no significant demographic differences between the pre-COVID-19 and COVID-19 cohorts. The 10 patients in the pre-COVID-19 cohort underwent a total of 15 neurosurgical and 10 otolaryngological procedures, while the 8 patients in the COVID-19 cohort underwent a total of 12 neurosurgical and 10 otolaryngological procedures. Surgically obtained wound cultures yielded a variety of organisms; Streptococcus constellatus/S. anginosus/S. intermedius were more prevalent in the COVID-19 cohort (87.5% vs 0%, p < 0.001) as was Parvimonas micra (62.5% vs 0%, p = 0.007). CONCLUSIONS: At an institutional level, there has been an approximately threefold increase in cases of sinusitis- and otitis media-related intracranial infections during the COVID-19 pandemic. Multicenter studies are needed to confirm this observation and to investigate whether the mechanisms of infection are related directly to SARS-CoV-2, changes in the respiratory flora, or delayed care. The next steps will include expansion of this study to other pediatric centers throughout the United States and Canada.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
