In this report, we present two cases of patients with cerebrospinal fluid (CSF) otorrhea who underwent surgical repair through either a transmastoid or middle cranial fossa approach. In our first case, a 34-year-old male after head trauma with conductive hearing loss and a House-Brackmann grade 2 facial palsy was found to have a soft tissue mass protruding through his right tympanic membrane. Radiological examination revealed a wide tegmen tympani defect. He underwent surgery via a transmastoid approach with repair of the defect and blind sac closure of the external auditory canal after middle ear cavity obliteration...

Background and objective Soccer is associated with repetitive head trauma, which, as it is known from sports like football and boxing, can result in hypopituitarism. Gonadotropins and GH are the most common pituitary hormones to become deficient. GH deficiency is associated with an increased risk of cardiovascular mortality and has negative influence on body mass index, visceral fat mass, insulin resistance and sensitivity, bone mineral density and inflammatory markers. Therefore the aim of this study was to evaluate the somatotrope pituitary function in professional soccer players...

Background: In contrast to patients with traumatic subarachnoid hemorrhage (tSAH) in the presence of other types of intracranial hemorrhage, the prognosis of patients with isolated tSAH is good. The incidence of mortality in these patients ranges from 0-2.5%. However, few data or predictive models are available for the identification of patients with a high mortality risk. In this study, we aimed to construct a model for mortality prediction using a decision tree (DT) algorithm, along with data obtained from a population-based trauma registry, in a Level 1 trauma center...

Abusive head trauma (AHT) is a potentially fatal result of child abuse, but the mechanisms by which injury occur are often unclear. To investigate the contention that shaking alone can elicit the injuries observed, effective computational models are necessary. The aim of this study was to develop a probabilistic model describing infant head kinematics in AHT. A deterministic model incorporating an infant's mechanical properties, subjected to different shaking motions, was developed in OpenSim. A Monte Carlo analysis was used to simulate the range of infant kinematics produced as a result of varying both the mechanical properties and the type of shaking motions...

OBJECTIVES: Among emergency physicians, there is wide variation in admitting practices for patients who suffered a mild traumatic brain injury (TBI) with an intracranial hemorrhage (ICH). The purpose of this study was to evaluate the effects of implementing a protocol in the emergency department (ED) observation unit for patients with mild TBI and ICH. METHODS: This retrospective cohort study was approved by the Institutional Review Board. Study subjects were patients ≥18 years of age with an International Classification of Diseases (ICD) code corresponding to a traumatic IC, and admitted to an ED observation unit (EDOU) of an urban, academic level 1 trauma center between February 1, 2015 and January 31, 2017...

INTRODUCTION: Pharmacological prophylaxis for early seizures following traumatic brain injury (TBI) is a recommendation in the Brain Trauma Foundation Guidelines. However, several studies have challenged the efficacy and safety of this practice, resulting in varied practice across centers around the world. The purpose of the present study was to compare the incidence of early clinical seizures following TBI, between two large centers, a US Center that practises routine seizure prophylaxis and a Chinese Center that does not use seizure prophylaxis following TBI...

Background: Dystrophic calcification can occur in any soft tissue with the absence of a systemic mineral imbalance and is often associated with trauma, infection, or inflammation. It is easily found in the site of the heart and skeletal muscles and rarely appears in the head and neck area. Case report: We present a rare case of multiple calcified masses in the left masseter muscle of a 26-year-old female with a history of trauma in the area. In computed tomography, multiple radiopaque masses were observed inside the left masseter muscle and blood test results were normal...

BACKGROUND: Blunt trauma is the most frequent mechanism of injury in multiple trauma, commonly resulting from road traffic collisions or falls. Two of the most frequent injuries in patients with multiple trauma are chest trauma and extremity fracture. Several trauma mouse models combine chest trauma and head injury, but no trauma mouse model to date includes the combination of long bone fractures and chest trauma. Outcome is essentially determined by the combination of these injuries...

REVIEW
Bruce B Horswell, Jason Sheikh
After a thorough review of the history and presentation of a child's facial pain, a targeted head and neck examination is critical to the appropriate diagnosis of facial pain and temporomandibular joint disorders. It is critical to distinguish between the structural (trauma, degenerative disease, and tumor) and nonstructural (neurogenic, myogenic, and psychological) causes of pain, which will allow for incorporation of appropriate strategies of medical, psychological, dental, and surgical therapies.

Sebastian Dieguez
Ganser's syndrome is a rare and controversial condition, whose main and most striking feature is the production of approximate answers (or near misses) to very simple questions. For instance, asked how many legs a horse has, Ganser patients will reply "5", and answers to plain arithmetic questions will likewise be wrong, but only slightly off the mark (e.g., 2 + 2 = 3). This symptom was originally described by Sigbert Ganser in 1897 in prisoners on remand and labeled Vorbeigehen ("to pass by"), although the term Vorbeireden ("to talk beside the point") is also frequently used...

INTRODUCTION: Pediatric head trauma is one of the commonest presentations to emergency departments. Over 90% of such head injuries are considered mild, but still present risk acute clinical deterioration and longer term morbidity. Identifying which children are at risk of clinically important brain injuries remains challenging and much of the data on minor head injuries is based on the adult population. CHALLENGES IN PEDIATRICS: Children, however, are different, both anatomically and in terms of mechanism of injury, to adults and, even within the pediatric group, there are differences with age and stage of development...

Thoracic and lumbar cortical bone trajectory pedicle screws have been described in adult spine surgery. They have likewise been described in pediatric CT-based morphometric studies; however, clinical experience in the pediatric age group is limited. The authors here describe the use of cortical bone trajectory pedicle screws in posterior instrumented spinal fusions from the upper thoracic to the lumbar spine in 12 children. This dedicated study represents the initial use of cortical screws in pediatric spine surgery...

In blunt force trauma to the head caused by attacks with blunt instruments, contact forces can be estimated based on the conservation of momentum if impact velocities are known. The aims of this work were to measure maximum striking velocities and to examine the influence of rod parameters such as rod mass and length as well as volunteer parameters such as sex, age, body height, body mass, body mass index and the average amount of physical exercise. Steel rods with masses of 500, 1000 and 1500 g as well as lengths of 40, 65 and 90 cm were exemplarily tested as blunt instruments...

Ischemic stroke is an uncommon cause of death among teenagers and young adults; however, the etiologies differ when compared to ischemic strokes in older individuals. Large-vessel atherosclerosis and small-vessel disease causing ischemic stroke are rare for the teenage population, while cervicocerebral arterial dissections account for up to 20% of ischemic strokes. Here, we present the case of a 16-year-old male who developed internal carotid artery dissection (ICAD) after a head injury and subsequently developed ischemic stroke and seizures...

Vertical femoral neck fractures (Pauwels type III classification) in young adults generally occur as a consequence of high-energy trauma and are frequently seen in association with multiple injuries. Considering the controversies regarding the optimal fixation for this fracture, our aim was to evaluate the clinical outcome of a closed fixation strategy for vertical femoral neck fractures in young adults using two parallel and one transverse cancellous lag screws. This was a single-surgeon, prospective study including 20 young adults with average age of 38...

Identifying the pathophysiology of posttraumatic stress disorder (PTSD) is a critical step toward reducing its debilitating impact. Spontaneous neural activity, measured at rest using various neuroimaging techniques (e.g., regional homogeneity [ReHo], amplitude of low frequency fluctuations [ALFF]), can provide insight about baseline neurobiological factors influencing sensory, cognitive, or behavioral processes associated with PTSD. The present study used activation likelihood estimation (ALE) to conduct the largest-to-date quantitative meta-analysis of spontaneous neural activity in PTSD, including 457 PTSD cases, 292 trauma-exposed controls (TECs), and 293 non-traumatized controls (NTCs) across 22 published studies...

Objective: Among pediatric injury, brain injury is a leading cause of death and disability. To improve outcomes, many developed countries built neurotrauma databank (NTDB) system but there was not established nationwide coverage NTDB until 2009 and there have been few studies on pediatric traumatic head injury (THI) patients in Korea. Therefore, we analyzed epidemiology and outcome from the big data of pediatric THI. Methods: We collected data on pediatric patients from 23 university hospitals including 9 regional trauma centers from 2010 to 2014 and analyzed their clinical factors (sex, age, initial Glasgow coma scale, cause and mechanism of head injury, presence of surgery)...

BACKGROUND: Diffuse axonal injury (DAI) on MRI has been associated with poor functional outcome after moderate-severe traumatic brain injury (msTBI). Yet, DAI assessment with highly-sensitive MRI-techniques is unfeasible in the acute trauma setting, and CT remains the key diagnostic modality despite its lower sensitivity. We sought to determine whether CT-defined-hemorrhagic-DAI (hDAI) is associated with discharge and favorable 3-and 12-month functional outcome (Glasgow Outcome Score ≥4) after msTBI...

OBJECTIVES: We reported on a patient with mild traumatic brain injury (TBI) who showed recovery of an injured cingulum concurrent with improvement of short-term memory, which was demonstrated on follow-up diffusion tensor tractography (DTT). METHODS: A 55-year-old male patient suffered head trauma resulting from falling from approximately 2 m while working at a construction site. The patient showed mild memory impairment (especially short-term memory impairment) at 3 months after onset: Memory Assessment Scale (global memory: 95 (37%ile), short-term memory: 75 (5%ile), verbal memory: 80 (9%ile) and visual memory: 112 (79%ile))...
