To identify the prevalence of traumatic brain injury (TBI), posttraumatic stress disorder (PTSD), and pain in Veterans from Operation Iraqi Freedom/Operation Enduring Freedom/Operation New Dawn (OIF/OEF/OND), Veterans who received any inpatient or outpatient care from Veterans Health Administration (VHA) facilities from 2009 to 2011 were studied. A subset of Veterans was identified who were diagnosed with TBI, PTSD, and/or pain (head, neck, or back) as determined by their International Classification of Diseases-9th Revision-Clinical Modification codes. Between fiscal years 2009 and 2011, 613,391 Veterans accessed VHA services at least once (age: 31.9 +/- 9.6 yr). ⋯ Results show that increasing numbers of Veterans from OIF/OEF/OND accessed VHA over a 3 year period. Among those with a TBI diagnosis, the majority also had a mental health disorder, with approximately half having both PTSD and pain. While the absolute number of Veterans increased by over 40% from 2009 to 2011, the proportion of Veterans diagnosed with TBI and the high rate of comorbid PTSD and pain in this population remained relatively stable.

Abusive head trauma among children in Alaska: a population-based assessment.
Serious physical abuse resulting in a traumatic brain injury (TBI) has been implicated as an underreported cause of infant mortality. Nearly 80% of all abusive head trauma (AHT) occurs among children <2 years of age, with infants experiencing an incidence nearly 8 times that of 2-year olds. ⋯ In Alaska, applying the CDC PAHT definition to the multi-source database enabled us to capture 49% more AHT cases than any of the individual database used in this analysis alone.

Amyloid-β Peptides and Tau Protein as Biomarkers in Cerebrospinal and Interstitial Fluid Following Traumatic Brain Injury: A Review of Experimental and Clinical Studies.
Traumatic brain injury (TBI) survivors frequently suffer from life-long deficits in cognitive functions and a reduced quality of life. Axonal injury, observed in many severe TBI patients, results in accumulation of amyloid precursor protein (APP). Post-injury enzymatic cleavage of APP can generate amyloid-β (Aβ) peptides, a hallmark finding in Alzheimer's disease (AD). ⋯ The heterogeneity of animal models, clinical cohorts, analytical techniques, and the complexity of TBI in the available studies make the clinical value of tau and Aβ as biomarkers uncertain at present. Additionally, the link between early post-injury changes in tau and Aβ peptides and the future risk of developing AD remains unclear. Future studies using methods such as rapid biomarker sampling combined with enhanced analytical techniques and/or novel pharmacological tools could provide additional information on the importance of Aβ peptides and tau protein in both the acute pathophysiology and long-term consequences of TBI.

ReviewRole of intravenous levetiracetam in seizure prophylaxis of severe traumatic brain injury patients.
Traumatic brain injury (TBI) can cause seizures and the development of epilepsy. The incidence of seizures varies from 21% in patients with severe brain injuries to 50% in patients with war-related penetrating TBI. In the acute and sub-acute periods following injury, seizures can lead to increased intracranial pressure and cerebral edema, further complicating TBI management. ⋯ Phenytoin is the most widely prescribed anticonvulsant in these patients. Intravenous levetiracetam, made available in 2006, is now being considered as a viable option in acute care settings if phenytoin is unavailable or not feasible due to side-effects. We discuss current data regarding the role of intravenous levetiracetam in seizure prophylaxis of severe TBI patients and the need for future studies.

Approximately 15% of casualties in the Afghanistan (Operation Enduring Freedom [OEF]) and Iraq (Operation Iraqi Freedom [OIF]) conflicts received mild traumatic brain injury (TBI). To identify Veterans who may benefit from treatment, the Department of Veterans Affairs (VA) implemented a national clinical reminder in 2007 to screen for TBI. Veterans who screen positive are referred for a comprehensive TBI evaluation. ⋯ Of the Veterans, 164,438 met inclusion criteria: 31,627 screened positive, 118,545 screened negative, and 14,266 received no TBI screening. Total healthcare costs of Veterans who screened positive, screened negative, or had no TBI screening were $9,610, $5,184, and $3,399, respectively (p < 0.001). Understanding these healthcare utilization and cost patterns will assist policymakers to address the ongoing and future healthcare needs of these returning Veterans.
