The tympanic plate is a small part of the temporal bone that separates the mandibular condyle from the external auditory canal. Fracture of this small plate is rare and usually associated with other bony fractures, mainly temporal and mandibular bone. There is a limited amount of literature on this subject, which increases the chance of cases being overlooked by physicians and radiologists. This is further supported by purely isolated cases of tympanic plate fracture without evidence of other bony fractures...

Introduction  The petrous apex poses a challenge for surgical intervention due to poor access. As intraoperative image guidance and surgical instrumentation improve, newer endoscopic approaches are increasingly favored. This study aims to provide normative data on the anatomy of the lateral sphenoid sinus recess and petrous apex. These normative data could assist in determining the efficacy of a transnasal transsphenoidal approach to lesions of the anteroinferior petrous apex. Methods  This is a retrospective study investigating normative data on all maxillofacial computed tomography (CT) scans performed at a level I trauma center over a 6-month period...

INTRODUCTION: We still lack understanding of why some implants fail while most remain stable after decades of use. Proinflammatory cytokines, matrix proteins and bone regulating cytokines of the RANKL/OPG (receptor activator of nuclear factor kappa B ligand/osteoprotegerin) and Wnt/β-catenin pathways are mandatory for normal bone repair but their spatial and temporal role in the healing of primary total hip arthroplasties (THA) has not been previously shown. MATERIALS AND METHODS: Twenty-four osteoarthritis patients with one-sided well-fixed primary THA were prospectively monitored during 18years (18Y) with repeated blood samples, clinical variables and radiographs...

Pneumolabyrinth has been considered an indicator of otic capsule involvement in temporal bone fractures. We present a novel theory for the etiology of pneumolabyrinth in a trauma patient without an otic capsule fracture: passage of intrathecal air into the labyrinth. Our patient experienced transient bilateral pneumolabyrinth after head trauma due to a motor vehicle collision. The patient was noted to have extensive pneumocephalus and a unilateral temporal bone fracture that spared the otic capsule. Initial computed tomography (CT) scans demonstrated air in the cochlea and both internal auditory canals...

BACKGROUND: Several factors are known contribute to hair cortisol concentration (HCC) in adults. However, there is less research on determinants of HCC in children and adolescents. HCC is a valuable tool for medical research pertaining to the hypothalamic-pituitary-adrenal (HPA) axis. This review aims to assess the extent to which established determinants of HCC in adults have been consistently reported in children (birth - 18 years) and to identify determinants of HCC specific to this age group...

BACKGROUND/PURPOSE: The classic "trimodal" distribution of death has been described in adult patients, but the timing of mortality in injured children is not well understood. The purpose of this study was to define the temporal distribution of mortality in pediatric trauma patients. METHODS: A retrospective cohort of patients with mortality from the National Trauma Data Bank (2007-2014) was analyzed. Categorical comparison of 'dead on arrival', 'death in the emergency department', and early (≤24h) or late (>24h) inpatient death was performed...

The aim of this study was to investigate the relationship among childhood trauma, executive impairments, and altered resting-state brain function in young healthy adults. Twenty four subjects with childhood trauma and 24 age- and gender-matched subjects without childhood trauma were recruited. Executive function was assessed by a series of validated test procedures. Localized brain activity was evaluated by fractional amplitude of low frequency fluctuation (fALFF) method and compared between two groups. Areas with altered fALFF were further selected as seeds in subsequent functional connectivity analysis...

Arachnoid cysts (ACs) are congenital malformations that may develop anywhere in the subarachnoid space along the cerebrospinal axis but are mostly observed in the temporal fossa and Sylvian fissure, predominantly in the left side. ACs account for 1% of all intracranial space-occupying lesions. ACs are a potential risk factor for subdural haematoma in all age groups following a traumatic head injury. Although an intracystic haemorrhage of AC without evidence of a head trauma is very rare, it may particularly develop in children and young adults who spend much more time engaged in games and forced physical exercise...

Traumatic spinal cord injury (SCI) often occurs in patients with concurrent traumatic injuries in other body systems. These patients with polytrauma pose unique challenges to clinicians. The current review evaluates existing guidelines and updates the evidence for prehospital transport, immobilization, initial resuscitation, critical care, hemodynamic stability, diagnostic imaging, surgical techniques, and timing appropriate for the patient with SCI who has multisystem trauma. Initial management should be systematic, with focus on spinal immobilization, timely transport, and optimizing perfusion to the spinal cord...

BACKGROUND: Posttraumatic stress disorder (PTSD) is a prevalent mental health issue among veterans. Access to PTSD treatment is influenced by geographic (ie, travel distance to facilities), temporal (ie, time delay between services), financial (ie, eligibility and cost of services), and cultural (ie, social stigma) barriers. OBJECTIVE: The emergence of mobile health (mHealth) apps has the potential to bridge many of these access gaps by providing remote resources and monitoring that can offer discrete assistance to trauma survivors with PTSD and enhance patient-clinician relationships...

AIMS: The Nucleus CI532 cochlear implant incorporates a new precurved electrode array, i.e., the Slim Modiolar electrode (SME), which is designed to bring electrode contacts close to the medial wall of the cochlea while avoiding trauma due to scalar dislocation or contact with the lateral wall during insertion. The primary aim of this prospective study was to determine the final position of the electrode array in clinical cases as evaluated using flat-panel volume computed tomography...

Skeletal tibial traction is a temporizing measure used preoperatively for femoral fractures to improve the length and alignment of the limb and provide pain relief. The goal of this study was to identify possible neurovascular morbidity associated with the use of bedside skeletal tibial traction to treat femur fractures. All femoral fractures treated with proximal tibial traction during a 10-year period at an urban level I trauma center were retrospectively reviewed. The medical record was reviewed to determine whether a pin-related complication had occurred...

Brain connectivity studies report group differences in pairwise connection strengths. While informative, such results are difficult to interpret since our understanding of the brain relies on region-based properties, rather than on connection information. Given that large disruptions in the brain are often caused by a few pivotal sources, we propose a novel framework to identify the sources of functional disruption from effective connectivity networks. Our approach integrates static and time-varying effective connectivity modeling in a probabilistic framework, to identify aberrant foci and the corresponding aberrant connectomics network...

OBJECTIVES: Childhood maltreatment is a non specific risk factor for eating disorders (EDs). However, no study assessed so far the impact of childhood maltreatment on brain structure of adults with EDs. Therefore, we investigated brain areas volumes and fiber tracts integrity of childhood maltreated (Mal) and non-maltreated (noMal) patients with EDs. METHODS: Thirty-six ED women and 16 healthy women underwent a MRI scanning including acquisition of a diffusion tensor imaging (DTI) sequence and a high resolution T1-weighted scan...

Diving air-breathing vertebrates have long been considered protected against decompression sickness (DCS) through anatomical, physiological, and behavioural adaptations. However, an acute systemic gas and fat embolic syndrome similar to DCS in human divers was described in beaked whales that stranded in temporal and spatial association with military exercises involving high-powered sonar. More recently, DCS has been diagnosed in bycaught sea turtles. Both cases were linked to human activities. Two Risso's dolphin (Grampus griseus) out of 493 necropsied cetaceans stranded in the Canary Islands in a 16-year period (2000-2015), had a severe acute decompression sickness supported by pathological findings and gas analysis...

BACKGROUND: Spontaneous intrauterine depressed skull fractures (IDSF) are rare fractures that often require neurosurgical evaluation and therapy. The majority of reported congenital depressions are secondary to maternal abdominal trauma or instrumentation during delivery. Spontaneous IDSF occur in the setting of uneventful normal spontaneous vaginal delivery (NSVD) or cesarean section, without obvious predisposing risk factors. The etiology and optimal management of spontaneous IDSF remain controversial...

CASE REPORT: The authors report two cases of arachnoid cysts (ACs) neither detected during pregnancy nor shortly after birth when newborns underwent CT scan evaluation after birth head trauma. ACs were diagnosed at 10 months and 6 years, respectively. The first one becomes symptomatic, and the other one was incidentally found during a head trauma investigation. DISCUSSION: These cases give support for the postnatal pathogenesis for some of the assumed congenital ACs...

A central hypothesis of recovered memory is that the source of the memory may be misattributed, and the memory of an imagined event may be mistaken as the memory of the perceived event that was not remembered. The judgment of memory source depends upon phenomenological characteristics. Thus, the present study investigated characteristics of recovered memory. To exclude potential confounding effects of traumatic stress and acute mental illness, data on recovered memories of diverse valences in a nonclinical sample were collected...
