Intellectual ability 10 years after traumatic brain injury in infancy and childhood: what predicts outcome?
The long-term consequences of child traumatic brain injury (TBI) are poorly understood, but there are indications of ongoing deterioration in skills with time since injury. This study investigated outcomes up to 10 years post-injury, to determine the influences of injury severity, injury age, and environment. The study design was prospective and longitudinal. ⋯ Predictors of 10-year outcome included pre-injury and social factors, injury age, and family function. Child survivors of serious TBI are at elevated risk of cognitive impairment, with recovery continuing into the third year post-injury. However, between 30 months and 10 years post-insult, children appear to make appropriate developmental gains, contrary to the speculation that these children "grow into their deficits."

What is the pressure in chronic subdural hematomas? A prospective, population-based study.
Surgery for chronic subdural hematoma (CSDH) is performed to relieve brain displacement and high intracranial pressure (ICP). However, the intraoperative impression is often that the pressure inside the CSDH is low, despite marked clinical symptoms. We wanted to quantify the CSDH pressure and relate this to radiological and clinical characteristics. ⋯ Our results are generally in line with those of previous studies reporting quantitative pressure registrations. However, there are important disparities regarding methodology, not least when comparing with various subjective scales that are widely used in clinical practice. A mean subdural pressure of 15.2 cm H(2)O is probably within the range of a normal ICP.

Increased risk of multiple sclerosis after traumatic brain injury: a nationwide population-based study.
The etiology of multiple sclerosis (MS) is still not well known. Previous data show conflicting results regarding the association between MS and prior brain trauma. This study aims to investigate the risk for MS following a traumatic brain injury (TBI) using a large-scale cohort study design. ⋯ Patients with TBI had a higher incidence of MS during the 6-year period than the comparison group (0.055% versus 0.037%). After excluding cases who died from non-MS causes, stratifying for hospitalization of cases as a proxy for severity, and adjusting for monthly income and geographic region of the community in which the patient resided, the hazard ratio (HR) of MS for patients with hospital-treated TBI injuries was 1.97 (95% CI 1.31,2.93, p<0.01) that of patients without TBI during the 6-year follow-up period after index health care use. Our study concludes that patients with TBI are at higher risk for subsequent MS over a 6-year follow-up period.
