Mild head trauma

This study correlated mild traumatic brain injury (mTBI) cognitive changes with ASL-MRI glymphatic clearance rates (GCRs) and recovery with GCR improvement. mTBI disrupts the blood brain barrier (BBB), reducing capillary mean transit time and GCRs. mTBI is clinically diagnosed utilizing history/examination findings with no physiologic biomarkers. 3D TGSE (turbo-gradient spin-echo) pulsed arterial spin-labeling 3T MRI with 7 long inversion times (TIs) assessed the signal clearance of labeled protons 2800-4000 ms postlabeling in bifrontal, bitemporal, and biparietal regions within 7 days of mTBI and once clinically cleared to resume activities...

OBJECTIVE: The purpose of this study was to identify the cerebral physiologic response to aerobic exercise in individuals with a symptomatic concussion, highlighting available knowledge and knowledge gaps in the literature. DESIGN: A systematic scoping review was conducted and reported in keeping with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews. A search of EMBASE, MEDLINE, SCOPUS, BIOSIS, and Cochrane libraries was conducted on June 15, 2023 (from database inception)...

INTRODUCTION: Post-intubation hypotension (PIH) is a risk factor of endotracheal intubation (ETI) after injury. For those with traumatic brain injury (TBI), one episode of hypotension can potentiate that injury. This study aims to identify the resuscitation adjuncts which may decrease the incidence of PIH in this patient population. METHODS: This is a 4-year (2019-2022) prospective observational study at a level I trauma center. Adult (≥18) patients with isolated TBI requiring ETI in the trauma bay were included...

BACKGROUND: Dural arteriovenous fistulas (AVFs) are reportedly induced by trauma. We report a rare case of traumatic AVF with a direct shunt from the middle meningeal artery (MMA) to the middle meningeal vein (MMV) and multiple drainage routes after head trauma. The patient was effectively treated with selective coil embolization alone without liquid embolic material. CASE DESCRIPTION: A 56-year-old woman was admitted to the emergency department with mild disturbance of consciousness caused by a head contusion after alcohol consumption...

OBJECTIVES: People may experience a myriad of symptoms after mild traumatic brain injury (mTBI), but the relationship between symptoms and objective assessments is poorly characterized. This study sought to investigate the association between symptoms, resting heart rate (HR), and exercise tolerance in individuals following mTBI, with a secondary aim to examine the relationship between symptom-based clinical profiles and recovery. METHODS: Prospective observational study of adults aged 18 to 65 years who had sustained mTBI within the previous 7 days...

OBJECTIVE: To examine the association between participation and satisfaction with life at 1, 2, 5, and 10 years after traumatic brain injury (TBI) in older adults. SETTING: Community. PARTICIPANTS: Participants (N = 2362) who sustained complicated mild to severe TBI, requiring inpatient rehabilitation, at age 60 years or older and had follow-up data on participation and satisfaction with life for at least 1 follow-up time point across 1, 2, 5, and 10 years...

OBJECTIVE: To investigate which factors within an at-risk group make patients less likely to benefit from preventive treatment following mild traumatic brain injury (mTBI). SETTING: Inclusion in 3 level I trauma centers in the Netherlands. Data collection through surveys as outpatients. PARTICIPANTS: mTBI patients (18-66 years), reporting 3 or more complaints 2 weeks postinjury (at-risk status). Eighty-four patients included and randomized (39 patients cognitive behavioral therapy, 45 patients telephonic counseling)...

OBJECTIVE: To map existing literature about concussion management in older people, identifying and analyzing gaps in our understanding. CONTEXT: Concussion injuries affect older people, yet little guidance is available about how to approach concussion management with older people. Research does not always include older populations, and it is unclear to what extent standard concussion management is appropriate for older people. DESIGN: Scoping review...

This study aimed to assess the prevalence, severity, and natural history of positional posterior plagiocephaly (PPP) and positional posterior brachycephaly in Japan. We conducted a cross-sectional study of pediatric patients, ranging from 0 to 15 years old, evaluated for head trauma with negative computed tomography (CT) findings. The cranial vault asymmetry index (CVAI) was calculated using CT images at the superior orbital rim. Asymmetry according to CVAI values was subcategorized as follows: mild (3.5%-7%), moderate (7%-12%), and severe (>12%)...

A retired oncologist describes the unexpected death of his wife, Claudia, who spent 25 years as head of the geriatrics service of a major VA hospital. The couple drew comfort in their orchestration of a "good death"; nevertheless they understood that her death was hastened by a number of missteps. In the 2 months following a hip fracture, a chain of complications that required five surgical interventions led to massive hemorrhage from necrotizing esophagitis. Claudia lacked resilience to recover from a sequence of traumas sustainable by a younger person-but even the most experienced geriatrician might not have identified or even suspected her risk...

BACKGROUND AND OBJECTIVES: Traumatic subarachnoid hemorrhage (tSAH) is a common consequence of head trauma. Treatment of tSAH patients commonly involves serial CT imaging to assess for expansile hemorrhage. However, growing evidence suggests that these patients rarely deteriorate or require neurosurgical intervention. We assessed the utility of repeat CT imaging in adult patients with isolated tSAH and an intact initial neurologic exam. METHODS: Patients presenting to Mass General Brigham Hospitals with tSAH between 2000 and 2021 were eligible for inclusion in this retrospective cohort study...

The aim of the present study was to investigate adverse effects of head injury, neck trauma, and chronic noise exposure on the complaint profile in people with Ménière's disease (MD). The study used a retrospective design. Register data of 912 patients with MD from the Finnish Ménière Federation database were studied. The data comprised case histories of traumatic brain injury (TBI), neck trauma and occupational noise exposure, MD specific complaints, impact related questions, and the E-Qol health-related quality of life instrument...

Approximately 16% of patients with mild traumatic brain injury (mTBI) develop a post-concussion syndrome (PCS) with persistent physical, neurological, and behavioral complaints. PCS has a great impact on a patient's quality of life, often decreases the ability to return to work, and henceforth has a great economic impact. Recent studies suggest that early treatment can greatly improve prognosis and prevent long-term effects in these patients. However, early recognition of patients at high risk of PCS remains difficult...

OBJECTIVE: We describe a patient with leukemia-related chronic subdural hematoma (CSDH) who was successfully treated using the combination of surgical evacuation and middle meningeal artery (MMA) embolization. CASE PRESENTATION: A 73-year-old man without apparent head trauma history was admitted to our hospital because of acute myeloid leukemia (AML). Head CT on admission revealed mild CSDH on both sides. Medical treatment options, including chemotherapy, were started...

Glanzmann thrombasthenia (GT) is a rare platelet disorder characterized by qualitative/quantitative deficiencies of the platelets' fibrinogen receptor, glycoprotein (GP) IIb/IIIa complex, resulting in impaired platelet aggregation and increased bleeding time. Most cases are hereditary with an autosomal recessive pattern of inheritance, but acquired GT also occurs. We report the surgical management of symptomatic chronic subdural hematoma (CSDH), a rare condition in young individuals, in a 37-year-old man who had GT and a history of mild head trauma approximately one month before admission...

BACKGROUND: Diagnostic accuracy of glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase L1 (UCH-L1) in identification of intracranial abnormalities detected by computed tomography (CT) in mild traumatic brain injury (mTBI), and in patients with mild neurological symptoms not caused by head trauma but suspected with a neurological disorder, was examined. METHODS: GFAP and UCH-L1 were determined using the chemiluminescence immunoassays on the Alinity i analyzer (Abbott Laboratories)...

INTRODUCTION: Cervicocephalic arterial dissections (CADs) occur in 3 cases per 100,000 individuals across all ages. Multiple simultaneous CADs are found in 13 to 22% of cases, and three or more dissections occur in approximately 2%. CADs might result from multifactorial intrinsic deficiencies of vessel wall integrity and extrinsic factors, e.g., minor trauma. CASE PRESENTATION: A young gentleman presented to the emergency department with a sudden onset of a spinning sensation of surrounding, left side arm weakness, blurring of vision, and an NIHSS score of 4...

Background partial pressure of carbon dioxide (PaCO2) is generally known to influence outcome in patients with traumatic brain injury (TBI) at normal altitudes. Less is known about specific relationships of PaCO2 levels and clinical outcomes at high altitudes. Methods This is a prospective single-center cohort of consecutive TBI patients admitted to a trauma center located at 2600 meter above sea level. An unfavorable outcome was defined as the Glasgow Outcome Scale-Extended (GOSE) < 4 at 6-month follow-up...

Angiocentric glioma (AG) is an extremely rare tumor that often develops in adolescents. Awake surgery for AG occurring in the eloquent area has not been reported to date. We report a case involving a right-handed 15-year-old boy with AG. He presented with a first-time generalized tonic-clonic seizure and was rushed to the local hospital. CT of the head indicated a left frontal low-density mass with no calcification. He was subsequently referred to our hospital. Comparison with a CT scan obtained two years prior due to mild head trauma indicated that the lesion showed a trend toward enlargement...

Repetitive mild traumatic brain injuries (r-mTBI) sustained in the military or contact sports have been associated with the accumulation of extracellular tau in the brain, which may contribute to the pathogenesis of neurodegenerative tauopathies. The expression of the apolipoprotein E4 (apoE4) isoform has been associated with higher levels of tau in the brain, and worse clinical outcomes after r-mTBI, though the influence of apoE genotype on extracellular tau dynamics in the brain is poorly understood. We recently demonstrated that extracellular tau can be eliminated across blood-brain barrier (BBB), which is progressively impaired following r-mTBI...
