ABSTRACT
Background: Abusive Head Trauma (AHT) is a syndrome of life-threatening intracranial injuries. The COVID-19 pandemic imposed new stresses upon socially vulnerable populations, but the relationships between social vulnerability, COVID-19 and AHT outcomes are not known. We investigated whether patient or social factors predicted survival after AHT and whether these factors and outcomes were modified during COVID-19. Methods: A single-institution database was queried for all admissions of children with a confirmed diagnosis of AHT from 2018-2021. Clinical information, radiographs and clinic follow-up data were reviewed. Social vulnerability index (SVI) was calculated based on published methods (atsdr.cdc.gov). Univariate and multivariate analyses were performed. Results: One hundred and three cases of AHT were reviewed. Median age at presentation was 4 months (IQR 2-10) in the overall cohort, males outnumbered females overall (76 males, 27 females). 18 patients died (17.5%), higher than previously reported rates. Nonsurvivors had higher social vulnerability index (.867 vs .719, p=0.004);71% had high social vulnerability compared to 39% of survivors. There was no difference in fatality rate before (19%) or during (15%) COVID-19. All nonsurvivors were intubated on admission, compared to 36% of survivors (p<0.001) and all nonsurvivors were comatose compared to 29% of survivors (p<0.001);61% of nonsurvivors had cardiac arrest on admission compared to 3% of survivors (p<0.001). The injury severity score of nonsurvivors was higher than that of survivors (27 vs 17, p=0.02 in univariate analysis). Nonsurvivors were less likely to have multiple fractures (11% vs. 43%, p=0.01). Nonsurvivors were more likely to have bilateral hypoxic ischemic injury (HII, 89% vs 29%, p< 0.001, Crude OR for survival 0.33, p<0.001, p=0.017 in multivariate analysis). There was no difference in rates or types of neurosurgical intervention, intracranial hemorrhage location, or presence of spinal hemorrhage between nonsurvivors and survivors. Discussion: Mortality from AHT in our series was higher than previously reported: more than one out of six children in our series did not survive. Although nonsurvivors were more likely to live in highly vulnerable social settings, COVID-19 did not change survival rate. Nonsurvivors are more likely to present in coma requiring intubation and in cardiac arrest. Subdural hematomas are seen in survivors and non-survivors but surgical mass lesions are rare and surgery does not improve survival. We identify a strong association between completed bilateral HII on admission and fatality in AHT. The high mortality of AHT in association with HII, and the low efficacy of intervention after completed HII supports a public health effort towards treatment and prevention focusing on socially vulnerable communities.
ABSTRACT
The full range of neurological manifestations of novel coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) infection in children remains incompletely characterized. Here, we discussed a 7-year-old male child patient with sickle cell disease (SCD), who presented with acute encephalopathy and nonconvulsive (electrographic only) seizures immediately prior to the onset of severe symptomatic SARS-CoV-2 infection, manifesting as respiratory failure, systemic inflammatory response, and hypertension. Brain imaging confirmed hyperintense lesions consistent with posterior reversible encephalopathy syndrome (PRES). Following aggressive symptomatic management including antiseizure medication, immunomodulatory treatment of SARS-CoV-2 infection, and intensive blood pressure control, he made a full neurological recovery. PRES has been observed in adults with SARS-CoV-2 infection, but there are few published reports of this neurological manifestation in children. Our case demonstrates that PRES should be a consideration in children with SARS-CoV-2 infection presenting with acute neurological decompensation, especially in the setting of preexisting risk factors for cerebrovascular dysregulation such as SCD.
