What Variables Correlate With Different Clinical Outcomes of Abusive Head Injury?

BACKGROUND: The spectrum of injury severity for abusive head trauma (AHT) severity is broad, but outcomes are unequivocally worse than accidental trauma. There are few publications that analyze different outcomes of AHT. OBJECTIVE: To determine variables associated with different outcomes of AHT. METHODS: Patients were identified using our AHT database. Three different, but not mutually exclusive, outcomes of AHT were modeled: (1) death or hemispheric stroke (diffuse loss of grey-white differentiation); (2) stroke(s) of any size; and (3) need for a neurosurgical operation. Demographic and clinical variables were collected and correlations to the 3 outcomes of interest were identified using bivariate and multivariable analysis. RESULTS: From January 2009 to December 2017, 305 children were identified through a prospectively maintained AHT database. These children were typically male (60%), African American (54%), and had public or no insurance (90%). A total of 29 children (9.5%) died or suffered a massive hemispheric stroke, 57 (18.7%) required a neurosurgical operation, and 91 (29.8%) sustained 1 or more stroke. Death or hemispheric stroke was statistically associated with the pupillary exam (odds ratio [OR] = 45.7) and admission international normalized ratio (INR) (OR = 17.3); stroke was associated with the pupillary exam (OR = 13.2), seizures (OR = 14.8), admission hematocrit (OR = 0.92), and INR (9.4), and need for surgery was associated with seizures (OR = 8.6). CONCLUSION: We have identified several demographic and clinical variables that correlate with 3 clinically applicable outcomes of abusive head injury.

Converting Pediatric Patients and Young Adults From a Shunt to a Third Ventriculostomy: A Multicenter Evaluation.

BACKGROUND: Endoscopic third ventriculostomy (ETV) is an effective primary treatment for certain forms of hydrocephalus. However, its use in children with an existing shunt is less well known. OBJECTIVE: To report a multicenter experience in attempting to convert patients from shunt dependence to a third ventriculostomy and to determine predictors of success. METHODS: Three participating centers provided retrospectively collected information on patients with an attempted conversion from a shunt to an ETV between December 1, 2008, and April 1, 2018. Demographic, clinical, and radiological data were recorded. Success was defined as shunt independence at the last follow-up. RESULTS: Eighty patients with an existing ventricular shunt underwent an ETV. The median age at the time of the index ETV was 9.9 yr, and 44 (55%) patients were male. The overall success rate was 64% (51/80), with a median duration of follow-up of 2.0 yr (range, 0.1-9.4 yr). Four patients required a successful repeat ETV at a median of 1.7 yr (range, 0.1-5.7 yr) following the index ETV. Only age was predictive of ETV failure on multivariate analysis (odds ratio 0.86 [95% CI 0.78-0.94], P = .005). No patient less than 6 mo of age underwent an ETV, and of the 5 patients between 6 and 12 mo of age, 4 failed. CONCLUSION: Although not every shunted patient will be a candidate for an ETV, nor will they be successfully converted, an ETV should at least be considered in every child who presents with a shunt malfunction or who has an externalized shunt.
