OBJECTIVEPast studies have suggested correlations between abusive head trauma and concurrent cervical spine (c-spine) injury. Accordingly, c-spine MRI (cMRI) has been increasingly used in radiographic assessments. This study aimed to determine trends in cMRI use and treatment, and outcomes related to c-spine injury in children with nonaccidental trauma (NAT).METHODSA total of 503 patients with NAT who were treated between 2009 and 2014 at a single pediatric health care system were identified from a prospectively maintained database. Additional data on selected clinical events were retrospectively collected from electronic medical records. In 2012, a clinical pathway on cMRI usage for patients with NAT was implemented. The present study compared cMRI use and clinical outcomes between the prepathway (2009–2011) and postpathway (2012–2014) periods.RESULTSThere were 249 patients in the prepathway and 254 in the postpathway groups. Incidences of cranial injury and Injury Severity Scores were not significantly different between the 2 groups. More patients underwent cMRI in the years after clinical pathway implementation than before (2.8% vs 33.1%, p < 0.0001). There was also a significant increase in cervical collar usage from 16.5% to 27.6% (p = 0.004), and more patients were discharged home with cervical collar immobilization. Surgical stabilization occurred in a single case in the postpathway group.CONCLUSIONSHeightened awareness of potential c-spine injury in this population increased the use of cMRI and cervical collar immobilization over a 6-year period. However, severe c-spine injury remains rare, and increased use of cMRI might not affect outcomes markedly.
Aim
This population‐based study aimed to estimate the impact of neonatal seizures on subsequent neurological outcomes, regardless of underlying etiology.
Method
We performed a retrospective cohort study (1st January 2009–31st December 2014), using a USA nationwide claims database. Newborn infants enrolled in 2009 were followed for up to 6 years. Neonatal seizures were identified by combining the International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code of 779.0 (convulsions in newborn), procedure codes of electroencephalogram and brain imaging, and antiepileptic drugs claims. Cox regression models were built to estimate the independent impact of neonatal seizures on developing epilepsy, intellectual disability, psychiatric/behavioral disorders, and headache.
Results
Out of 490 071 newborn infants (251 850 males [51.4%], 238 221 females [48.6%]), 800 neonatal seizure cases were identified. After controlling for sex, birthweight, preterm birth status, and underlying etiology, neonates with seizures were more likely to have epilepsy (hazard ratio=32.7; 95% confidence interval [CI]=27.7−38.7; p<0.001), intellectual disability (hazard ratio=2.0; 95% CI=1.8−2.3; p<0.001), and headache (hazard ratio=1.6; 95% CI=1.1−2.2; p=0.013) than those without seizures.
Interpretation
Observed covariates being equal, seizures in neonates appeared to play a significant role in developing epilepsy, intellectual disability, and headache. The findings showed a detrimental impact of the event in the very early life on neurological outcomes in later life.
What this paper adds
Seizures had their own impact on the development of adverse neurological outcomes.
The magnitude of impact was quite large in epilepsy.
This study aims to assess recurrence risk in developmentally and neurologically normal children with a newly diagnosed unprovoked seizure. The medical record was retrospectively reviewed in 393 children who had a newly diagnosed, unprovoked seizure. A total of 152 children met inclusion criteria. The relationship between seizure recurrence and variables was examined. Seventy cases had recurrent seizures. Total 113 cases had follow-up data and 70 cases of these (63.7%) experienced recurrent seizures. EEG was abnormal in 65 (44.8%): focal epileptiform abnormality in 34 cases (23.4%) and generalized epileptiform abnormality in 23 cases (15.9%). Brain MRI revealed any structural abnormality in 14 of 86 cases (16.3%). Neither EEG abnormality nor brain MRI abnormality was statistically significantly associated with increased seizure recurrence in this cohort. Further study is required to confirm the EEG and brain MRI findings in otherwise normal children with a newly diagnosed unprovoked seizure.
