A Resident-Led Firearm Curriculum for Pediatrics Residents Improves Safe Storage Counseling.

OBJECTIVE: To develop and implement a resident-led firearm safety curriculum, delivered to pediatrics residents, and to evaluate outcomes. STUDY DESIGN: A firearm safety curriculum was developed in 2019-2020 at a single academic center, using Kern's framework and cognitive load theory. The curriculum was organized using the "Be SMART" firearm safety model. Sessions were led by resident peers. The content included workshops on firearm safety counseling, advocacy training, and a gun lock program in collaboration with the local police department. Content was integrated into existing residency didactic curriculum. Impact was measured by a pre/posttest knowledge assessment and a systematic chart review. RESULTS: The curriculum was provided to 41/66 (62%) pediatrics residents. Knowledge improved (67% to 77% correct) when comparing pre-intervention with post-intervention. A total of 1477 charts were reviewed. Compared with a historical cohort, participants more often asked about presence of a firearm (27% vs 69%, P < .0001) and counseled on firearm safety (9% vs 25%, P < .0001). In the post-intervention timeframe, 25% of eligible families were provided a gun lock. CONCLUSIONS: A firearm safety curriculum designed by pediatrics residents and administered to their peers resulted in a statistically significant improvement in inquiries about firearm ownership and safety counseling in an urban tertiary care continuity clinic. These results demonstrate the promising outcomes of a firearm safety program developed by residents and delivered to peers.

Environmental Influences on Risk and Disease Course in Pediatric Multiple Sclerosis.

Pediatric multiple sclerosis (MS) accounts for 3%-10% of all patients diagnosed with MS. Complex interplay between environmental factors impacts the risk for MS and may also affect disease course. Many of these environmental factors are shared with adult-onset MS. However, children with MS are in closer temporal proximity to the biological onset of MS and have less confounding environmental exposures than their adult counterparts. Environmental factors that contribute to MS risk include: geographical latitude, viral exposures, obesity, vitamin deficiencies, smoking, air pollution, perinatal factors, gut microbiome, and diet. More recently, research efforts have shifted to studying the impact of these risk determinants on the clinical course of MS. In this article we will examine relevant environmental risk determinants of pediatric MS and review the current knowledge on how these factors may contribute to pediatric MS disease evolution.

The baseline risk of multiple febrile seizures in the same febrile illness: a meta-analysis.

The baseline risk for multiple febrile seizures within the same febrile illness is largely unknown. Estimates range from 5 to 30%. Imprecise estimates can lead to incorrectly powering studies investigating the management of febrile seizures. To estimate the risk of multiple febrile seizures in the same febrile illness, we systematically reviewed and conducted a meta-analysis of studies from January 2000 to December 2021 that contained data for the number of children for both simple and complex febrile seizures in the same febrile illness. We searched MEDLINE, EMBASE, and Web of Science for randomized, quasi-randomized, prospective, and retrospective trials that involved children with febrile seizures. A total of 23,131 febrile illnesses with febrile seizures met the inclusion criteria. The estimated baseline risk of multiple febrile seizures in the same febrile illness was 17% (95% CI, 16-19%). However, the 30 cohorts that included both admitted and non-admitted patients had a lower percentage of multiple FSs within the same illness (14%; 95% CI, 12-15%) than the 30 cohorts that enrolled only admitted patients (20%; 95% CI, 16-25%). CONCLUSION: Researchers can use estimates in this paper to design future studies. Taking into the account the substantial heterogeneity between countries and studies, clinicians could cautiously use our estimates in their clinical assessment and be better able to set parental expectations about a child's chances of having another febrile seizure during the current illness. TRIAL REGISTRATION: PROSPERO CRD42020191784. Registered July 18, 2020. WHAT IS KNOWN: • There is renewed interest in the diagnostic workup and prophylactic treatment of febrile seizures to prevent repeat seizures in the same febrile illness. • There is a lack of accurate estimates of the baseline risk for multiple febrile seizures in the same illness to properly design studies investigating management. WHAT IS NEW: • This study provides the most robust estimates for the baseline risk for multiple febrile seizures in the same illness.

Acute flaccid myelitis a review of the literature.

Acute flaccid myelitis (AFM) is a rare neurological disorder that first rose to national attention in 2014. This neurological disorder has a biennial presentation with every other even year being a peak year. Most patients present in childhood 5 days after a prodromal infection. Patients usually present with muscle weakness and hypo or areflexia in the summer or fall months. Clinical outcomes are variable however most patients do not improve. Currently there are no definitive prognostic factors or etiologies found. However, it is thought that enterovirus-D68 (EV-D68) could be a potential component in the pathobiology of AFM. Treatment options are limited with variable options and no consensus. Supportive therapy has been shown to be the most effective thus far. With our review of the literature, we highlight the recent growing evidence of a possible relationship between EV-D68 and AFM. Additionally, we identify the knowledge gaps in AFM with treatment and prognostic factors.

Child Neurology: Hypotonia and Delayed Teeth Eruption in a 2-Year-Old Girl.

POLR3-related disorders are rare hypomyelinating leukodystrophies associated with hypodontia. We present a female patient, who was referred to pediatric neurology at 2 years of age for tremor, low tone, and motor delays. In addition, she was noted to have a delay in her teeth eruption and myopia. Neurologic examination was significant for ataxic features and global developmental delay. Laboratory workup was unrevealing. MRI was significant for hypomyelination. Genetic testing confirmed a pathogenic variant of POLR3B POLR3-related leukodystrophies should be considered in patients who present with hypotonia, ataxia, and hypodontia. There are many different subtypes of POLR-related leukodystrophies each with distinguishing phenotypic and radiographic features. Although MRI can be helpful in initial evaluation, genetic testing is needed for confirmatory diagnosis and to guide prognosis.
