Children who sustained nonaccidental head trauma (NAHT) are at severe risk for mortality within the first 24 hours after presentation. ⋯ Patients presenting to medical care 6-12 hours after NAHT (moderate delay) appeared to have worse outcomes than those presenting earlier or later.

Traumatic brain injury (TBI) is divided into primary and secondary brain injury. Primary brain injury occurs at the time of injury and is the direct consequence of kinetic energy acting on the brain tissue. Secondary brain injury occurs several hours or days after primary brain injury and is the result of factors including shock, systemic hypotension, hypoxia, hypothermia or hyperthermia, intracranial hypertension, cerebral oedema, intracranial bleeding or inflammation. ⋯ The lungs and urinary tract were the most common sites of infection. In conclusion, elevated inflammatory markers (white blood cell count and CRP) and hyperglycaemia are associated with secondary brain injury. The lack of routine use of intracranial pressure (ICP) monitoring may explain the high mortality rate and the occurrence of secondary stroke in patients with TBI.

Observational StudyEvaluation of S100B in the diagnosis of suspected intracranial hemorrhage after minor head injury in patients who are receiving platelet aggregation inhibitors and in patients 65 years of age and older.
Cranial CT (CCT) scans and hospital admission are increasingly performed to rule out intracranial hemorrhage in patients after minor head injury (MHI), particularly in older patients and in those receiving antiplatelet therapy. This leads to high radiation exposure and a growing financial burden. The aim of this study was to determine whether the astroglial-derived protein S100B that is released into blood can be used as a reliable negative predictive tool for intracranial bleeding in patients after MHI, when they are older than 65 years or being treated with antiplatelet drugs (low-dose aspirin, clopidogrel). ⋯ Levels of S100B below 0.105 μg/L can accurately predict normal CCT findings after MHI in older patients and in those treated with PAIs. Combining conventional decision criteria with measurement of S100B can reduce the CCT scan and hospital admission rates by approximately 30%.

To determine the incidence, predictors, and outcomes of generalized convulsive status epilepticus (GCSE) in traumatic brain injury (TBI) patients. ⋯ Despite its low incidence, GCSE in TBI patients was associated with worse outcomes with threefold higher in-hospital mortality, prolonged hospitalization, higher hospital charges, and worse discharge disposition. Surprisingly, epilepsy is a negative predictor of GCSE in this population.

Comparative Study Observational StudyComparison of predictability of Marshall and Rotterdam CT scan scoring system in determining early mortality after traumatic brain injury.
Marshall computed tomographic (CT) classification is widely used as a predictor of outcome. However, this grading system lacks the following variables, which are found to be useful predictors: subarachnoid/intraventricular hemorrhage, extradural hematoma, and extent of basal cistern compression. A new classification called the Rotterdam grading system, incorporating the above variables, was proposed later. In the original paper, this system was found to have superior discrimination as compared to Marshall grading, however, Rotterdam grading has not been validated widely. We aimed to compare the discriminatory power of both grading systems. ⋯ Both Marshal and Rotterdam grading systems are good in predicting early mortality after moderate and severe TBI. As the Rotterdam system also includes additional variables like subarachnoid hemorrhage, it may be preferable, particularly in patients with diffuse injury.
