Subgaleal Collection: An Unusual Presentation of a Scalp Mass in a Pediatric Patient.

Subgaleal fluid collection is a rare phenomenon of scalp swelling among young infants and, in many cases, adolescents. As fluid accumulates in the subgaleal space, it presents as a soft, ill-defined, fluctuant, mobile swelling not limited to suture lines. This condition is associated with vacuum-assisted devices and forceps during delivery in infancy. Beyond infancy, this condition can be seen spontaneously or, most commonly, after minor head traumas. Such minor traumas that have been reported in recent years include hair pulling or hair braiding. Early recognition of this condition and its complications is essential for appropriate treatment and management. In this case report, we highlight the importance of subgaleal fluid collection being considered a differential diagnosis of headaches, particularly in children and adolescents who present with excessive hair pulling or hair braiding.

The Use of Middle Meningeal Artery Embolization to Treat Chronic Subdural Hematoma in the Pediatric Population: A Review of the Literature.

Chronic subdural hematoma (cSDH) is rare in the pediatric population and typically arises from various causes. These include trauma (accidental, non-accidental, or birth-related injuries), coagulopathies (such as hemophilia or von Willebrand disease), vascular malformations (such as arteriovenous malformations), and complications from previous surgeries. These diverse etiologies contribute to the complexity of managing this condition. Although middle meningeal artery (MMA) embolization is proven effective in adults, limited studies have investigated its applicability in pediatrics. This study aims to assess the efficacy, safety, and outcomes of MMA embolization in the pediatric age group, guiding future research and treatment strategies. A systematic review of the literature was conducted using PubMed, Web of Science, and Embase. No restrictions were applied regarding publication status or follow-up duration. The inclusion criteria were studies that integrated MMA embolization as a treatment for cSDH in pediatric patients. Data extracted included patient sample and characteristics, cSDH etiology and characteristics, prior intervention, procedural technique and indication, and clinical and radiological outcomes. Twelve studies were included in the review, comprising a total of 14 patients. There were no randomized clinical trials or large-scale cohort studies. The included literature consisted of 11 case reports and one case series, and the results described a clinical and radiological outcome in a varied mix of patients with different characteristics and backgrounds for cSDH. No neurological complications attributed to MMA embolization were reported. Follow-up showed resolved or decreased size of cSDH in all patients except for one, who experienced hematoma expansion despite treatment. MMA embolization may be considered a primary or adjuvant treatment modality for cSDH in the pediatric population. However, further research is needed to investigate the impact of different etiologies on outcomes and to highlight long-term complications and results.

Severe donor reaction as a hazard of replacement blood donation.

Blood donation is generally considered to be a safe procedure, but occasionally adverse reactions of varying severity may occur predonation, donation, or postdonation phases. Various studies have reported the incidence of adverse donor reaction as 0.6%-5.6%. Donor reactions are classified into mild, moderate, and severe types or immediate and delayed. Although delayed reactions account for <2% of total adverse donor reactions, 27.6% are severe with or without injury. Herein, we report a case of potentially preventable delayed Grade 2 vasovagal reaction in a 56-year-old replacement blood donor.

Comparison of concordance and predictive validity of head injuries from parental reports and medical records.

OBJECTIVE: To examine agreement between parental reports of head injury and evidence of head injury in medical records and to compare these two measures in predicting early conduct disorder (CD). DESIGN AND SETTING: Parent survey data was compared with records of child head injury from the National Health Services Register (Régie de l'assurance maladie du Québec, RAMQ) administrative database. PARTICIPANTS: Children (N = 685) ages 6-9 with and without CD. There were 147 children with RAMQ recorded head injury and 39 children with parent-reported head injury. MAIN MEASURES: Indication of one or more head injury before 6 years of age as reported by parents and/or as noted in medical data. Early CD (present by age 9) according to parents and/or teachers. RESULTS: Results indicated poor agreement between the two forms of reporting κ = .161 (95% CI, .083 to .239), p < 0.001. Medical data significantly predicted the presence of CD in children, with a RAMQ coded head injury suggesting a child was 1.88 times more likely to have CD. Parent reports of head injuries did not significantly predict CD. Conclusion: Medical data should be prioritized in research addressing pediatric head injury, given that parent reports may fail to capture incidence of injury and therefore may be less predictive of other known correlates of head injury.

A rare case of herpes simplex virus encephalitis from viral reactivation following surgically treated traumatic brain injury.

OBJECTIVE: Herpes simplex virus encephalitis (HSVE) is associated with significant morbidity and mortality. Here, we present the occurrence of HSVE in a 36-year-old immunocompetent patient following craniotomy for a traumatic acute subdural hematoma (ASDH). METHODS: Imaging after four days of progressive headache following a fall with head-strike demonstrated a 1 cm thick left holohemispheric ASDH with significant cerebral compression, edema, and 8 mm of left-to-right midline shift, and an emergent craniotomy and ASDH evacuation were performed, with additional treatment needed for reaccumulation. Postoperatively, the patient developed a worsening leukocytosis, became febrile, and was hypotensive requiring vasopressor support. RESULTS: Despite empiric antibiotics, the patient remained persistently febrile with significant leukocytosis. Repeat head CT showed a new left insular hypodensity and a subsequent viral encephalitis panel was positive for HSV-1. The patient was then started on intravenous acyclovir, with progressive neurological exam improvement. Of note, the patient was noted to have a positive serum HSV-1 IgG antibody titer, indicative of prior infection. CONCLUSIONS: Given the known systemic immunosuppression in brain injury and the high prevalence of HSV seropositivity, clinicians should consider the possibility of HSVE from HSV reactivation in TBI patients with persistent fever, leukocytosis, and/or neurological deficits without an obvious etiology.

Profile of Mortal Injuries in Vehicular Accidents: An Autopsy-Based Study.

Background It is crucial to analyze the trends of fatal injuries among pedestrians, passengers, motorcycle riders, and drivers of three- and four-wheelers in traffic accidents. Objective To ascertain the trend of fatal injuries to the head, chest, and abdomen across different victim categories in vehicular accidents. Materials and methods An autopsy-based prospective study was carried out in the mortuary of a rural tertiary care hospital. A total of 108 fatal cases of vehicular accidents were taken into consideration. All natural and unnatural deaths, other than those stemming from vehicle crashes, were excluded from this study; only the victims of fatal vehicular accidents were included. Results Males outnumbered female victims by 8.8:1. The age range of 41-60 years was the most affected (38.9%). The greatest number of victims (17, or 15.8%) were male motorcycle riders in the range of 21-40 years. Most vehicular mishaps (61; 56.5%) occurred during the evening. The most frequent injury pattern reported was head injuries (53.4%). Conclusions Motorcycle riders constituted the most severely injured victim category in a vehicular accident. Most mishaps occurred in the dark because of inadequate lighting or bad road conditions in rural areas. Furthermore, the most frequently occurring type of injury was an injury to the head, which may be an outcome of riders' lack of compliance with the mandatory helmet-use policy.

Pediatric sport and nonsport concussions presenting to emergency departments: injury circumstances, characteristics, and clinical management.

OBJECTIVE: The aim of this study was to compare injury circumstances, characteristics, and clinical management of emergency department (ED) presentations for sports-related concussion (SRC) and non-SRC. METHODS: This multicenter prospective observational study identified patients 5-17 years old who presented to EDs within 24 hours of head injury, with one or more signs or symptoms of concussion. Participants had a Glasgow Coma Scale score of 13-15 and no abnormalities on CT (if performed). Data were stratified by age: young children (5-8 years), older children (9-12 years), and adolescents (13-17 years). RESULTS: Of 4709 patients meeting the concussion criteria, non-SRC accounted for 56.3% of overall concussions, including 80.9% of younger child, 51.1% of older child, and 37.0% of adolescent concussions. The most common mechanism of non-SRC was falls for all ages. The most common activity accounting for SRC was bike riding for younger children, and rugby for older children and adolescents. Concussions occurring in sports areas, home, and educational settings accounted for 26.2%, 21.8%, and 19.0% of overall concussions. Concussions occurring in a sports area increased with age, while occurrences in home and educational settings decreased with age. The presence of amnesia significantly differed for SRC and non-SRC for all age groups, while vomiting and disorientation differed for older children and adolescents. Adolescents with non-SRC were admitted to a ward and underwent CT at higher proportions than those with SRC. CONCLUSIONS: Non-SRC more commonly presented to EDs overall, with SRC more common with increasing age. These data provide important information to inform public health policies, guidelines, and prevention efforts.

Concussions in ice hockey: mixed methods study including assessment of concussions on games missed and cap hit among National Hockey League players, systematic review, and concussion protocol analysis.

OBJECTIVE: Concussions can occur at any level of ice hockey. Incidence estimates of concussions in ice hockey vary, and optimal prevention strategies and return-to-play (RTP) considerations have remained in evolution. The authors performed a mixed-methods study with the aim of elucidating the landscape of concussion in ice hockey and catalyzing initiatives to standardize preventative mechanisms and RTP considerations. METHODS: The authors performed a five-part mixed-methods study that includes: 1) an analysis of the impact of concussions on games missed and income for National Hockey League (NHL) players using a publicly available database, 2) a systematic review of the incidence of concussion in ice hockey, 3) a systematic review of preventative strategies, 4) a systematic review of RTP, and 5) a policy review of documents from major governing bodies related to concussions in sports with a focus on ice hockey. The PubMed, Embase, and Scopus databases were used for the systematic reviews and focused on any level of hockey. RESULTS: In the NHL, 689 players had 1054 concussions from the 2000-2001 to 2022-2023 seasons. A concussion led to a mean of 13.77 ± 19.23 (range 1-82) games missed during the same season. After cap hit per game data became available in 2008-2009, players missed 10,024 games due to 668 concussions (mean 15.13 ± 3.81 per concussion, range 8.81-22.60 per concussion), with a cap hit per game missed of $35,880.85 ± $25,010.48 (range $5792.68-$134,146.30). The total cap hit of all missed games was $385,960,790.00, equating to $577,635.91 per concussion and $25,724,052.70 per NHL season. On systematic review, the incidence of concussions was 0.54-1.18 per 1000 athlete-exposures. Prevention mechanisms involved education, behavioral and cognitive interventions, protective equipment, biomechanical studies, and policy/rule changes. Rules prohibiting body checking in youth players were most effective. Determination of RTP was variable. Concussion protocols from both North American governing bodies and two leagues mandated that a player suspected of having a concussion be removed from play and undergo a six-step RTP strategy. The 6th International Conference on Concussion in Sport recommended the use of mouthguards for children and adolescents and disallowing body checking for all children and most levels of adolescents. CONCLUSIONS: Concussions in ice hockey lead to substantial missed time from play. The authors strongly encourage all hockey leagues to adopt and adhere to age-appropriate rules to limit hits to the head, increase compliance in wearing protective equipment, and utilize high-quality concussion protocols.

Macroscopic and histological examination of human bridging veins.

In infantile abusive head injury (AHT), subdural haemorrhage (SDH) is commonly held to result from traumatic damage to bridging veins traversing from the surface of the brain to the dura and dural venous sinuses. However, there are limited published radiological or autopsy demonstrations of ruptured bridging veins and several authors also assert that bridging veins are too large to rupture due to the forces associated with AHT. There have been several studies on the size, locations and numbers of adult bridging veins and there is one small study of infant bridging veins. However, there are no microscopic studies of infant bridging veins and only a select few ultrastructural investigations of adult bridging veins. Hitherto, it has been assumed that bridging veins from infants and younger children will display the same anatomical characteristics as those in adulthood. At 19 neonatal, infant and young child post-mortem examinations, we macroscopically examined and sampled bridging veins for microscopy. We compared the histology of those samples with bridging veins from an older child and two adults. We demonstrate that adult bridging veins are usually surrounded by supportive meningeal tissue that appears to be lacking or minimally present around the bridging veins of younger children. Neonatal, infant and young children's veins had a free 'bridging' section. Neonatal and infant bridging veins had smaller diameter ranges and thinner walls (some only 5-7 µm) than those seen in older children and adults. Bridging vein walls contained both fine strands of elastic fibers and a more pronounced elastic lamina. The presence of an elastic lamina occurred more frequently in the older age groups These anatomical differences between the veins of adults and young children may help to explain apparent increased vulnerability of neonatal/infant bridging veins to the forces associated with a shaking-type traumatic event.

Head injuries related to bicycle collisions and helmet use - an observational study.

OBJECTIVES: In Denmark, the use of bicycles is widespread, and head injuries are often seen in cyclists involved in collisions. Despite the well-known effects of using a helmet to reduce head injuries, using helmets is not mandatory in Denmark. The primary objective of this study was to provide data regarding injury outcomes and helmet usage. METHODS: Participants were bicyclists who sustained head injuries in bicycle collisions and were assessed by the Copenhagen Emergency Medical Services between 1 January 2016; and 15 June 2019. Patients with suspected head injury were identified in an electronic prehospital patient record. Data were linked to the Danish National Patient Registry to retrieve the diagnosis and were categorized into head injury or no head injury based on the diagnosis. Adjusted logistic regression analyses were reported with odds ratios and corresponding confidence intervals to assess the risk of head injury while adjusting for risk factors like age, sex, alcohol consumption, occurrence during weekends and traumatic brain injury. RESULTS: A total of 407 patients were included in this study. Within this entity, 247 (61%) had sustained a head injury. The use of a helmet was reported in one-third of the included patients. Among the head-injured patients, 13% sustained moderate to severe head injuries. Patients with suspected alcohol involvement were significantly less likely to report the use of a helmet. Helmet use reduced the risk of head injury with an odds ratio of 0.52, (95% CI 0.31 - 0.86). In high-energy trauma, the use of a helmet showed a significant reduction in the risk of sustaining a head injury with an odds ratio of 0.28, (95% CI 0.12 - 0.80). CONCLUSIONS: In this study, using a helmet was associated with a significantly decreased risk of head injury; this association was even more significant in high-energy trauma.

WHITE CEREBELLUM SIGN AS A DARK PROGNOSTIC INDICATOR OF CEREBRAL INJURY: A CASE REPORT.

Introduction: The white cerebellum sign (WCS) is a classical but rare radiological finding usually associated with irreversible diffuse hypoxic-ischemic cerebral injury. Very few cases exist in the literature globally, especially from the West African region, as a potential hallmark of poor prognostic outcome. We describe the white cerebellum sign in a Nigerian pediatric patient, managed for severe head injury. Case Presentation: A fourteen-year old boy presented to our emergency department with loss of consciousness following a pedestrian road traffic accident. Physical examination revealed a critically ill boy with fever, hypotension, tachycardia, gasping respiration, GCS 3, bilateral dilated unreactive pupils, absent corneal, gag and oculocephalic reflexes. He was thus diagnosed of severe traumatic brain injury and brainstem dysfunction. He had endotracheal intubation, ventilatory and inotropic support. Cranial computerized tomography scan of the patient showed radiological features in keeping with the WCS. His clinical status remained poor until he suffered a cardiac arrest about twelve hours after admission. Conclusion: WCS has been reported in relation to child abuse, anoxic-ischemic brain injury, inflammatory and metabolic brain disorders and trauma. It is a classical radiological description of diffuse cerebral edema alongside relatively normal cerebellar hemispheres and brainstem. Management of this pathology is symptomatic, and aims to ameliorate the associated raised intracranial pressure, control seizures and prevent cerebral infarction. The index patient, who presented 24 hours after severe head injury with associated early post-traumatic seizures, respiratory failure and brainstem dysfunction, had an unfavourable outcome consistent with previous reports of WCS. We have reported the rare but classical white cerebellum sign. It remains a grave prognosticator of cerebral injury and should be sought for in the neuroimaging of patients with acute brain insults.

Comparison of scoring systems for patients with head injury presenting to the emergency department.

PURPOSE: The present study aimed to compare the National Emergency X-Radiography Utilization Study II (NEXUS-II), New Orleans Criteria (NOC), Canadian Computed Tomography (CT) Head Rule (CCTHR) scoring systems, and Advanced Trauma Life Support (ATLS®) 10th edition algorithm in patients with head injury presenting to the emergency department and to investigate the effectiveness of these scoring systems in determining injury severity and the need for cranial CT scanning. METHODS: This prospective and observational study was conducted in a tertiary care emergency medicine clinic. The study included 794 adult patients who had a Glasgow Coma Scale (GCS) score ≥ 13, and were considered as having minor head injury. Patients included in the study were categorized as having low or high risk according to the CCTHR, NOC, NEXUS-II scores, and ATLS algorithm. RESULTS: The mean age of the patients was 40.7 ± 18.7 years, and 592 (74.6%) were male. The proportion of patients considered as having high risk was 27.7%, 84.8%, and 34.5% according to CCTHR, NOC, and NEXUS-II, respectively. According to the ATLS, 14.7% and 14.1% of the patients were considered at medium risk and high risk, respectively. CT scanning was performed in 757 (95.3%) patients, and pathologic findings were detected in 18 patients (2.3%). NOC in contrary showed a sensitivity of 100% but a specificity of 15.6%. CONCLUSION: In our region, there was no significant difference among the CCTHR, NEXUS-II systems, and ATLS algorithm regarding the accuracy of pathological findings in patients with head injury; any of these systems can be used in clinical practice and determining CT scan necessity. Although the sensitivity of the NOC system is very high, it has been observed that its low specificity may lead to a large number of unnecessary CT scans, which may increase the patient-based cost and waiting time in the emergency department.

Neuropharmacology in Traumatic Brain Injury.

One of the primary goals in traumatic brain injury (TBI) treatment is to minimize secondary brain damage and promote neuroprotection. In TBI rehabilitation, we seek to facilitate neurologic recovery and restore what independence is possible given a patient's physical and cognitive impairments. These goals must be balanced with treatment of the various symptoms that may occur following TBI. This is challenging given the fact that many of the typical treatments for certain symptoms also come with side effects which could be problematic in the TBI population.

Awareness of Shaken Baby Syndrome among Saudi Nursing Students: A Cross-Sectional Study.

Child abuse is a global problem. Shaken baby syndrome (SBS) is a result of child abuse, with shaking being the most common form of maltreatment, causing mortality or severe brain damage in infants. A lack of awareness of SBS among current and future healthcare professionals can have serious consequences. To date, no studies have been conducted in Saudi Arabia to examine student nurses' awareness of SBS, so we sought to assess this issue in an academic institution in Riyadh, Saudi Arabia. For this questionnaire-based study, we employed a cross-sectional, descriptive design. The target population was nursing students from every year of study in the institution's five-year undergraduate nursing programme, who received an online questionnaire during the 2022-2023 academic year. The data were analysed using descriptive and inferential statistical analysis. Of the 293 respondents, 100.0% confirmed that they were not aware of SBS through their nursing curricula, and 62.1% reported not being made aware of SBS at all during their academic journey. The majority of participants were unaware of the negative consequences of shaking a baby. Most were not aware that shaking a baby vigorously can cause permanent blindness (73.4%), postural impairments (56.7%), sleep disorders (61.1%), or convulsions (60.1%). The results of our study revealed a statistically significant relationship between nursing students' awareness of SBS and both their year of study and marital status. Those at higher academic levels and those who were married were more aware of SBS. To improve nursing students' knowledge of SBS and help them to better inform the public of this syndrome, particularly parents, child maltreatment topics should be added to nursing curricula in Saudi Arabia, and their importance should be emphasised. This will help reduce the prevalence and burden of SBS nationally.

Overutilization of head computed tomography in cases of mild traumatic brain injury: a systematic review and meta-analysis.

Head computed tomography (CT) is the preferred imaging modality for mild traumatic brain injury (mTBI). The routine use of head CT in low-risk individuals with mild TBI offers no clinical benefit but also causes notable health and financial burden. Despite the availability of related guidelines, studies have reported considerable rate of non-indicated head CT requests. The objectives were to provide an overall estimate for the head CT overutilization rate and to identify the factors contributing to the overuse. A systematic review of PubMed, Scopus, Web of Science, and Embase databases was conducted up to November 2023, following PRISMA and MOOSE guidelines. Two reviewers independently selected eligible articles and extracted data. Quality assessment was performed using a bias risk tool, and a random-effects model was used for data synthesis. Fourteen studies, encompassing 28,612 patients, were included, with 27,809 undergoing head CT scans. Notably, 75% of the included studies exhibited a moderate to high risk of bias. The overutilization rate for pediatric and adult patients was 27% (95% CI: 5-50%) and 32% (95% CI: 21-44%), respectively. An alternative rate, focusing on low-risk pediatric patients, was 54% (95% CI: 20-89%). Overutilization rates showed no significant difference between teaching and non-teaching hospitals. Patients with mTBI from falls or assaults were less likely to receive non-indicated scans. There was no significant association between physician specialty or seniority and overuse, nor between patients' age or sex and the likelihood of receiving a non-indicated scan. Approximately one-third of head CT scans in mTBI cases are avoidable, underscoring the necessity for quality improvement programs to reduce unnecessary imaging and its associated burdens.

Assessment of Hearing in Patients with Head Injury: A Prospective Study.

Background: Hearing impairment is a well-known outcome of head trauma. The most prevalent site of injury is the peripheral structures. Hearing loss dissipates in most cases but can continue in some cases and may improve in some. Objectives: To evaluate the incidence of hearing loss and ascertain its type and degree in patients with head injury. To estimate the progression or regression of hearing loss in head injury patients during follow-up. Material and Methods: 60 patients with head injuries with any ear symptoms were included in the study. The severity of head injury is graded according to the Glasgow Coma Scale (GCS). Patients were subjected to High Resolution Computed Tomogram (HRCT) temporal bone, and Pure Tone Audiometry (PTA) was performed within 24 h of presenting. PTA repeated after 3 months. The degree of hearing loss and its progression or regression were assessed. Results: Of the 60 patients, 56 (93.3%) had hearing loss on PTA. 50 Cases (83.3%) showed conductive hearing loss (CHL). 6 (10%) had mixed hearing loss (MHL). 4 cases with MHL had a transverse temporal bone fracture on radiological evaluation. 41 (68.3%) had mild CHL, 4 (6.7%) had moderate MHL, and 2 (3.3%) had moderately severe MHL. PTA values reduced significantly from 1st to 2nd visit in both ears. Conclusion: In our study, there was significant improvement in hearing during follow-up, after 3 months of head injury indicating improvement in hearing. The improvement in hearing was noticed in all cases except for one case with transverse temporal bone fracture and moderately severe hearing loss. Routine otological examination should be considered in all patients with head injuries. Meticulous and timely management of these cases can significantly reduce morbidity in the patient.

Incidentally detected ectopic maxillary tooth in an asymptomatic adult male: A rare case scenario.

Ectopic teeth, growing in abnormal locations like the maxillary sinus, are rare occurrences, with uncertain causes including trauma, infection, and developmental abnormalities. They often appear in the second or third decade of life, sometimes without symptoms. They are often missed as symptoms can mimic chronic sinusitis but may include sinonasal issues like obstruction and facial pain. Complications ranging from recurrence to potential blindness or carcinoma have been reported. Diagnosis involves radiographic imaging, with CT scans providing precise localization. Following accurate diagnosis, treatment typically involves surgical removal, with endoscopic procedures gaining popularity due to reduced risks. Follow-up for asymptomatic cases can be conducted through periodic radiographs. We report a case of maxillary ectopic tooth as an incidental finding in an asymptomatic patient presenting to the emergency department with head trauma.

ZL006 mitigates anxiety-like behaviors induced by closed head injury through modulation of the neural circuit from the medial prefrontal cortex to amygdala.

Closed head injury is a prevalent form of traumatic brain injury with poorly understood effects on cortical neural circuits. Given the emotional and behavioral impairments linked to closed head injury, it is vital to uncover brain functional deficits and their driving mechanisms. In this study, we employed a robust viral tracing technique to identify the alteration of the neural pathway connecting the medial prefrontal cortex to the basolateral amygdala, and we observed the disruptions in neuronal projections between the medial prefrontal cortex and the basolateral amygdala following closed head injury. Remarkably, our results highlight that ZL006, an inhibitor targeting PSD-95/nNOS interaction, stands out for its ability to selectively reverse these aberrations. Specifically, ZL006 effectively mitigates the disruptions in neuronal projections from the medial prefrontal cortex to basolateral amygdala induced by closed head injury. Furthermore, using chemogenetic approaches, we elucidate that activating the medial prefrontal cortex projections to the basolateral amygdala circuit produces anxiolytic effects, aligning with the therapeutic potential of ZL006. Additionally, ZL006 administration effectively mitigates astrocyte activation, leading to the restoration of medial prefrontal cortex glutamatergic neuron activity. Moreover, in the context of attenuating anxiety-like behaviors through ZL006 treatment, we observe a reduction in closed head injury-induced astrocyte engulfment, which may correlate with the observed decrease in dendritic spine density of medial prefrontal cortex glutamatergic neurons.

Head Injury and Associated Sequelae in Individuals Seeking Asylum in the United States: A Retrospective Mixed-Methods Review of Medico-Legal Affidavits.

People seeking asylum are susceptible to head injury (HI) due to exposure to various forms of violence including war, torture, or interpersonal violence. Yet, the extents to which clinicians assess HI, and if so, what the associated characteristics are, are not well known. We analyzed 200 U.S.-based medico-legal affidavits using descriptive, multivariate regression, and thematic analysis. Head injury was documented in 38% of affidavits. Those who experienced physical violence were eight times likelier to experience HI than those who did not experience physical violence. Five themes emerged: (1) HI occurred commonly in the context of interpersonal violence (44%), followed by militarized violence (33%); (2) mechanisms of HI included direct blows to the head and asphyxiation, suggesting potential for both traumatic brain injury and brain injury from oxygen deprivation; (3) HI was often recurrent and concurrent with other physical injuries; (4) co-morbid psychiatric and post-concussive symptoms made it challenging to assess neurological and psychiatric etiologies; and (5) overall, there was a paucity of assessments and documentation of HI and sequelae. Among individuals assessed for asylum claims, HI is common, often recurrent, occurring in the context of interpersonal violence, and concurrent with psychological and other physical trauma. Physical violence is an important risk factor for HI, which should be assessed when physical violence is reported.

Anxiety and Mood Disruption in Collegiate Athletes Acutely Following Mild Traumatic Brain Injury.

OBJECTIVE: To report the symptom burden of anxiety and mood-related indicators following mTBI in collegiate student-athletes. STUDY DESIGN: Retrospective cohort study of varsity collegiate athletes. SETTING: University sports medicine at a tertiary care center. PATIENTS: Division I college varsity athletes diagnosed with mTBI at a single institution between 2016 and 2019. INDEPENDENT VARIABLES: Pre- and post-injury. MAIN OUTCOME MEASURES: Comparisons between baseline testing and post-mTBI symptom scale assessments were made to determine changes in scores at the individual and group levels. The primary outcome was the prevalence of post-mTBI symptoms from within 72 h of injury through return to play. Associations with sport, sex, age, and return-to-play time were included. RESULTS: Compared to baseline, mood and anxiety symptom scores were significantly higher acutely following mTBI (2.1 ± 3.3 vs. 14.3 ± 12.2; p < 0.001). A family history of migraine was significantly associated with higher mood and anxiety symptom scores (20.0 ± 14.9 with history vs. 13.3 ± 11.3 without history; p = 0.042). Mood and anxiety symptom scores were highly correlated with non-mood and anxiety symptom scores for all athletes, including the subgroup with prolonged symptoms (r = 0.769; p < 0.001). CONCLUSIONS: Symptoms of anxiety or mood disruption are common during the acute period post-injury in varsity college athletes. Risk factors for higher symptom reports immediately following mTBI and for prolonged symptoms (>10 days) included female sex, those with a family history of migraine, and those with an overall higher symptom burden post-injury.
