This paper shows that extraction and analysis of various acoustic features from speech using mobile devices can allow the detection of patterns that could be indicative of neurological trauma. This may pave the way for new types of biomarkers and diagnostic tools. Toward this end, we created a mobile application designed to diagnose mild traumatic brain injuries (mTBI) such as concussions. Using this application, data was collected from youth athletes from 47 high schools and colleges in the the Midwestern United States...

Temporal bone fractures can occur as a result of various head trauma. The most common cause of the hemotympanum is traumatic temporal bone fracture. Facial paralysis and hearing loss can be seen associated with temporal bone fracture. The development of the internal carotid artery aneurysm after temporal bone fracture is extremely rare. In this article, the authors evaluated carotid artery aneurysm that developed after temporal fracture and aneurism compressed by coagulated blood mass which showed itself as a hemotympanum...

Arachnoid cysts are congenital, benign, non-neoplastic, extra-axial intra-arachnoidal lesions. Arachnoid cysts rarely become symptomatic, with bleeding. Intracranial haemorrhage as a complication of arachnoid cyst is a very rare condition. It is well-known that mid-cranial fossa cysts might cause intracerebral haemorrhage or subdural haematoma secondary to traumas. However, the occurrence of spontaneous subdural haematoma secondary to arachnoid cysts, developing without any trauma, is even rarer. A 17-year-old boy presenting with diplopia and headache, with no history of trauma, was diagnosed with left temporal lobe arachnoid cyst and left fronto-parietal subdural haematoma...

Expanded polytetrafluoroethylene (ePTFE) has been extensively used for facial soft tissue augmentation procedures, and is regarded as safe and reliable and suitable as a permanent implant. This implant is generally used in the lower third of the face for lips filling, nasal augmentation, nasolabial folds and chin augmentation, and rarely for congenital or acquired depressed deformities of the face. The aim of the present study was to assess the effects of ePTFE in congenital or acquired depressed deformities of the face...

OBJECTIVE: Minor head trauma is common in children. Though most cases are nonsignificant, minor head trauma can lead to the deterioration of intracranial injuries, which is preventable. The aim of this study was to identify clinical predictors of intracranial injuries in infants with minor head trauma. METHODS: We retrospectively enrolled infants under 11 months with minor head trauma between 2006 and 2013. The following data were recorded: age, sex, cause of trauma, fall height, vomiting, bad temper, size and location of scalp hematoma, fracture, and intracranial injuries on CT...

BACKGROUND: Prior work examining emotional dysregulation observed in posttraumatic stress disorder (PTSD) has primarily been limited to fear-learning processes specific to anticipation, habituation, and extinction of threat. In contrast, the response to threat itself has not been systematically evaluated. OBJECTIVE: To explore potential disruption in fear conditioning neurocircuitry in service members with PTSD, specifically in response to predictable versus unpredictable threats...

The styloid process arising from the temporal bone is normally about 2.5 cm in length. For various reasons, including trauma and inflammation, it may become elongated. This elongated styloid process, when symptomatic with clinical signs and symptoms suggestive of local compression or neuropathic pain, is termed Eagle syndrome. Glossopharyngeal neuralgia is characterized by intermittent shooting sharp pain in the jaw, throat, tongue, and ear. Conservative management includes anticonvulsants, tricyclic antidepressants, and anti-inflammatory agents...

BACKGROUND: Over the last decade the age of trauma patients and injury mortality has increased. At the same time, many centers have implemented multiple interventions focused on improved hemorrhage control, effectively resulting in a bleeding control bundle of care. The objective of our study was to analyze the temporal distribution of trauma-related deaths, the factors that characterize that distribution and how those factors have changed over time at our urban level 1 trauma center...

BACKGROUND: Applying manual pressure after hemorrhage is intuitive, cost-free, and logistically-simple. When direct abdominal-pelvic compression fails, clinicians can attempt indirect proximal-external-aortic-compression (PEAC), while expediting transfer and definitive rescue. This study quantifies the sustainability of simulated bi-manual PEAC both immediately on scene and during subsequent ambulance transfer. The goal is to understand when bi-manual PEAC might be clinically-useful, and when to prioritize compression-devices or endovascular-occlusion...

BACKGROUND: Childhood trauma increases risk of a range of mental disorders including psychosis. Whereas the mechanisms are unclear, previous evidence has implicated atypical processing of emotions among the core cognitive models, in particular suggesting altered attentional allocation towards negative stimuli and increased negativity bias. Here, we tested the association between childhood trauma and brain activation during emotional face processing in patients diagnosed with psychosis continuum disorders...

INTRODUCTION: The Utstein-style recommendations for reporting etiology and outcome in out-of-hospital cardiac arrest (OHCA) from 2004 have recently been revised. Among other etiologies a medical category is now introduced, replacing the cardiac category from Utstein template 2004. AIM: The aim of this study is to describe characteristics and temporal trends from reporting OHCA etiology according to the revised Utstein template 2014 in regards to patient characteristics and 30-day survival rates...

Cochlear implant insertion should be as least traumatic as possible in order to reduce trauma to the cochlear sensory structures. The force applied to the cochlea during array insertion should be controlled to limit insertion-related damage. The relationship between insertion force and histological traumatism remains to be demonstrated. Twelve freshly frozen cadaveric temporal bones were implanted with a long straight electrodes array through an anterior extended round window insertion using a motorized insertion tool with real-time measurement of the insertion force...

BACKGROUND: Joint impact injuries initiate a progressive articular damage finally leading to post-traumatic osteoarthritis (PTOA). Racehorses represent an ideal, naturally available, animal model of the disease. Standardbred racehorses developing traumatic osteoarthritis of the fetlock joint during the first year of their career were enrolled in our study. Age-matched controls were contemporarily included. Biomarker levels of equine osteoarthritis were measured in serum and synovial fluid (SF) at baseline, and repeated yearly over the next 4 years of training (from T1 to T4)...

The ability to form long-lasting memories is critical to survival and thus is highly conserved across the animal kingdom. By virtue of its complexity, this same ability is vulnerable to disruption by a wide variety of neuronal traumas and pathologies. To identify effective therapies with which to treat memory disorders, it is critical to have a clear understanding of the cellular and molecular mechanisms which subserve normal learning and memory. A significant challenge to achieving this level of understanding is posed by the wide range of distinct temporal and spatial profiles of molecular signaling induced by learning-related stimuli...

The cognitive and behavioural deficits caused by traumatic brain injury (TBI) to the immature brain are more severe and persistent than TBI in the mature brain. Understanding this developmental sensitivity is critical as children under four years of age sustain TBI more frequently than any other age group. Microglia (MG), resident immune cells of the brain that mediate neuroinflammation, are activated following TBI in the immature brain. However, the type and temporal profile of this activation and the consequences of altering it are still largely unknown...

BACKGROUND: Although PTSD-major depressive disorder (MDD) co-morbidity is well-established, the vast majority of studies have examined comorbidity at the level of PTSD total severity, rather than at the level of specific PTSD symptom clusters. This study aimed to examine the long-term associations between MDD and PTSD symptom clusters (intrusion, avoidance, hyperarousal), and the moderating role of gender in these associations. METHODS: 942 residents of urban Detroit neighborhoods were interviewed at 3 waves, 1 year apart...

OBJECTIVE The incidence of posttraumatic ventriculomegaly (PTV) and shunt-dependent hydrocephalus after nonaccidental head trauma (NAHT) is unknown. In the present study, the authors assessed the timing of PTV development, the relationship between PTV and decompressive craniectomy (DC), and whether PTV necessitated placement of a permanent shunt. Also, NAHT/PTV cases were categorized into a temporal profile of delay in admission and evaluated for association with outcomes at discharge. METHODS The authors retrospectively reviewed the cases of patients diagnosed with NAHT throughout a 10-year period...

Cochlear implant (CI) is an artificial electronic device which can provide a sense of sound to a patient with severe or profound hearing loss. Pathological changes have been observed after CI surgery, which might influence the effectiveness of the CI procedure. In this review, we divided the postoperative pathological changes of the temporal bone into two categories according to different stages: immediate trauma and delayed side effects. Immediate trauma might arise from traumatic insertion of the electrode during CI surgery, which included trauma at cochleostomy site, lateral wall trauma, basilar membrane injury, osseous lamina fracture and modiolar injury...

OBJECTIVE: Acquired epilepsy is a devastating long-term risk of various brain insults, including trauma, stroke, infections, and status epilepticus (SE). There is no preventive treatment for patients at risk. Due to the complex alterations involved in epileptogenesis, it is likely that multi-targeted approaches are required for epilepsy prevention. We report novel preclinical findings with isoflurane, which exerts various non-anesthetic effects that may be relevant for anti-epileptogenesis...

HYPOTHESIS: Scala tympani morphology influences the insertion dynamics and intra-scalar position of straight electrode arrays. BACKGROUND: Hearing preservation is the goal of cochlear implantation with current thin straight electrode arrays. These hug the lateral wall, facilitating full, atraumatic insertions. However, most studies still report some postoperative hearing loss. This study explores the influence of scala tympani morphology on array position relative to the basilar membrane and its possible contribution to postoperative hearing loss...
