The aim of the study was to investigate clinical features of headache associated with minor versus moderate to severe traumatic brain injury and of posttraumatic versus primary headache in children and adolescents. Study group included 74 patients after mild (n = 60) or moderate to severe (n = 14) traumatic brain injury identified by retrospective review of the computerized files of a tertiary pediatric headache clinic. Forty patients (54%) had migraine-like headache, 23 (31.1%) tension-like headache, and 11 (14.9%) nonspecified headache. ⋯ In comparison with 174 control patients, the study group had a significantly lower proportion of patients with migraine-like headache and a higher proportion of male patients and patients with allodynia. There was no statistically significant correlation of any of the clinical parameters with the type or severity of the posttraumatic headache or rate of allodynia. The high rate of allodynia in the study group may indicate a central sensitization in posttraumatic headache.

OBJECTIVE The Brain Trauma Foundation recommendation regarding the timing of surgical evacuation of epidural hematomas and subdural hematomas is to perform the procedure as soon as possible. Indeed, faster evacuation is associated with better outcome. However, to the authors' knowledge, no study has looked at where delays in intrahospital care occurred for patients suffering from traumatic intracranial mass lesions. ⋯ CONCLUSIONS A long delay until surgery still exists for patients requiring urgent mass lesion evacuation. Many factors contribute to this delay, including performing imaging and transfer to and preparation in the OR. Strategies can be implemented to reduce delays and improve the delivery of care.

Detection of Growth Hormone Deficiency in Adults with Chronic Traumatic Brain Injury.
This study examined the prevalence of growth hormone deficiency (GHD) in patients with traumatic brain injury (TBI) during the post-acute phase of recovery and whether GHD was associated with increased disability, decreased independence, and depression. A secondary objective was to determine the accuracy of insulin-like growth factor-1 (IGF-1) levels in predicting GHD in patients with TBI. Anterior pituitary function was assessed in 235 adult patients with TBI through evaluation of fasting morning hormone levels. ⋯ Symptoms of depression were also more prevalent in this group. In addition, patients with severe GHD had delayed admission to post-acute rehabilitation. This study confirms the high prevalence of GHD in patients with TBI and the necessity to monitor clinical symptoms and perform provocative testing to definitively diagnose GHD.

Guidelines suggest that Traumatic Brain Injury (TBI) related hospitalizations are best treated at Level I or II trauma centers because of continuous neurosurgical care in these settings. This population-based study examines TBI hospitalization treatment paths by age groups. ⋯ Utilization of trauma center resources for hospitalized TBIs may be low considering the established lower mortality rate associated with treatment at Level I or II trauma centers. The higher transfer rate for older adults may suggest rapid decline amid an unrecognized initial need for a trauma center care. A better understanding of hospital destination decision making is needed for patients with TBI.

Mild traumatic brain injury decreases broadband power in area CA1.
Cognitive impairment caused by traumatic brain injury (TBI) can lead to devastating consequences for both patients and their families. The underlying neurological basis for TBI-induced cognitive dysfunction remains unknown. However, many lines of research have implicated the hippocampus in the pathophysiology of TBI. ⋯ Here, we recorded in vivo electrophysiological activity in the hippocampi of 16 mice, 8 of which had previously undergone a TBI. Consistent with previous data, we found that theta power in the hippocampus was decreased in TBI animals compared to sham controls; however, this effect was driven by changes in broadband power and not theta oscillations. This result suggests that broadband fluctuations in the hippocampal local field potential can be used as an electrophysiological surrogate of abnormal neurological activity post-TBI.
