Comparison of Two Predictive Models for Short-Term Mortality in Patients after Severe Traumatic Brain Injury.

The Glasgow Coma Scale (GCS) and the Abbreviated Injury Score of the head region (HAIS) are validated prognostic factors in traumatic brain injury (TBI). The aim of this study was to compare the prognostic performance of an alternative predictive model including motor GCS, pupillary reactivity, age, HAIS, and presence of multi-trauma for short-term mortality with a reference predictive model including motor GCS, pupil reaction, and age (IMPACT core model). A secondary analysis of a prospective epidemiological cohort study in Switzerland including patients after severe TBI (HAIS >3) with the outcome death at 14 days was performed.

Primary leptomeningeal melanocytosis in a 10-year-old girl: a challenging diagnosis with a poor prognosis.

Primary leptomeningeal melanocytosis is rarely encountered in the pediatric population. Despite being considered a nonmalignant condition, it uniformly carries a poor prognosis given the ineluctable progression of meningeal infiltration. The case of a previously healthy 10-year-old girl who was first thought to suffer from recurrent hemiplegic migraine is reported.
