The main objective of this study was to evaluate the incidence of delayed complications in acute head injury (HI) patients with an initial normal head computed tomography (CT). ⋯ In the present study, which includes head injuries of all severity, the probability of delayed life-threatening complications was negligible when the primary CT scan revealed no acute traumatic lesions.

To present a case of a traumatic fracture of a polymethyl methacrylate (PMMA) patient-specific implant (PSI) for cranioplasty. ⋯ PMMA PSIs are commonly used for large defects and generally have good outcomes with low rates of revision. The case report described involves a shattered PMMA PSI after a traumatic impact, which resulted in hemiparesis. The question arises if this type of complication can be easily avoided with the addition of titanium onlay to restrict displacement in the event of fracture. This onlay represents a minor change of technique that could prevent migration of fracture fragments.

Neurological dysfunction after traumatic brain injury (TBI) is associated with pathology in cortical, subcortical, and brainstem nuclei. Our laboratory has reported neuropathology and microglial activation in the somatosensory barrel cortex (S1BF) and ventral posterior medial thalamus (VPM) after diffuse TBI in the rat, which correlated with post-injury whisker sensory sensitivity. The present study extends our previous work by evaluating pathology in whisking-associated sensory and motor brainstem nuclei. ⋯ In contrast, the VIIN showed non-significant neuropathology and reduced labeling of activated Iba1 microglia over 1 month post-injury. Together with our previous data, neuropathology and neuroinflammation in the whisker somatosensory pathway may contribute to post-injury sensory sensitivity more than the motor pathway. Whether these findings are direct results of the mechanical injury or consequences of progressive degeneration remains to be determined.

To characterize and compare our current series of patients to prior reports in order to identify any changes in the incidence of neurological injury related to hunting accidents in Rochester, New York. ⋯ Falls from hunting tree stands are still common, with a high rate of neurological injury. Compared to a decade ago we have made no progress in preventing these neurological injuries, despite an increase in safety advances. Neurosurgeons must continue to advocate for increased safety awareness and participate in leadership roles to improve outcomes for hunters.
