OBJECTIVES: Penetrating gunshot head injuries have a poor prognosis and require prompt care. Brain CT is a routine component of the standard evaluation of head wounds and suspected brain injury. We aimed to investigate the effect of brain CT findings on mortality in gunshot head injury patients who were admitted to our emergency department (ED) from the Syrian Civil War. METHODS: The study group comprised patients who were admitted to the ED with gunshot brain injury...

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...

Introduction. Labyrinthine concussion is a term used to describe a rare cause of sensorineural hearing loss with or without vestibular symptoms occurring after head trauma. Isolated damage to the inner ear without involving the vestibular organ would be designated as a cochlear labyrinthine concussion. Hearing loss is not a rare finding in head trauma that involves petrous bone fractures. Nevertheless it generally occurs ipsilateral to the side of the head injury and extraordinarily in the contralateral side and moreover without the presence of a fracture...

Body composition and muscle function have important implications for falls and fractures in older adults. We aimed to investigate longitudinal associations between sarcopenic obesity and its components with bone mineral density (BMD), and incident falls and fractures, in Australian community-dwelling older men. 1,486 men aged ≥70 years from the Concord Health and Ageing in Men Project (CHAMP) study were assessed at baseline (2005-2007), 2 year follow-up (2007-2009; N = 1,238), and 5 year follow-up (2010-2013; N = 861)...

Bone fracture healing is processed through multiple biological stages including the transition from cartilaginous callus to bony callus formation. Because of its specific, temporal and indispensable functions demonstrated by mouse genetic studies, Hedgehog (Hh) signaling is one of the most potent signaling pathways involved in these processes, but the effect of Hh-signaling activation by small compounds on the repair process had not yet been addressed. Here we examined therapeutic effects of local and one shot-administration of the Hh agonist known as smoothened agonist (SAG) on bone fracture healing in a mouse model...

INTRODUCTION: Although bilateral facial nerve palsy is a rare condition, its etiology is more detectable than the unilateral type. A temporal bone fracture is one cause of bilateral facial nerve palsy, contributing in 3% of the cases. CASE PRESENTATION: Here, we report the case of a 35-year-old man complaining of bilateral incomplete eye closure, two weeks after a closed head injury caused by a motor vehicle accident. CONCLUSIONS: The high resolution computed tomography findings revealed a bilateral temporal bone fracture line, which extended to the fallopian canal...

Because changes in the mechanical properties of bone are closely related to trabecular bone remodeling, methods that consider the temporal morphological changes induced by adaptive remodeling of trabecular bone are needed to estimate long-term fracture risk and bone quality in osteoporosis. We simulated bone remodeling using simplified and pig trabecular bone models and estimated the morphology of healthy and osteoporotic cases. We then displayed the fracture risk of the remodeled models based on a cumulative histogram from high stress...

Traumatic injury to the temporal bone can lead to significant morbidity or mortality and knowledge of the pertinent anatomy, pathophysiology of injury, and appropriate management strategies is critical for successful recovery and rehabilitation of such injured patients. Most temporal bone fractures are caused by motor vehicle accidents. Temporal bone fractures are best classified as either otic capsule sparing or otic capsule disrupting-type fractures, as such classification correlates well with risk of concomitant functional complications...

BACKGROUND: Resection of cranial tumors involving both bone and scalp tissue may require the recruitment of soft tissue using a flap above the bone reconstruction. When a transposition flap has been chosen, the alopecia zone on the donor site may be difficult to treat afterward. Scalp expansion is the gold standard in these situations, but this has never been described above cranial implants. We report the first case of a patient who underwent a scalp tissue expansion above a custom-made hydroxyapatite cranial implant to correct sequelar alopecia...

Osteogenesis imperfecta (OI) Type VI is characterized by a defect in bone mineralization, which results in multiple fractures early in life. Null mutations in the PEDF gene, Serpinf1, are the cause of OI VI. Whether PEDF restoration in a murine model of OI Type VI could improve bone mass and function was previously unknown. In Belinsky et al, we provided evidence that PEDF delivery enhanced bone mass and improved parameters of bone function in vivo. Further, we demonstrated that PEDF temporally inhibits Wnt signaling to enhance osteoblast differentiation...

Recent meta-analyses report a 70 % increase in fracture risk in selective serotonin reuptake inhibitor (SSRI) users compared to non-users; however, included studies were observational and limited in their ability to establish causality. Here, we use the Bradford Hill criteria to explore causality between SSRIs and fractures. We found a strong, consistent, and temporal relationship between SSRIs and fractures, which appears to follow a biological gradient. However, specificity and biological plausibility remain concerns...

Macrophages, the primary cells of the inflammatory response, are major regulators of healing, and mediate both bone fracture healing and the inflammatory response to implanted biomaterials. However, their phenotypic contributions to biomaterial-mediated bone repair are incompletely understood. Therefore, we used gene expression and protein secretion analysis to investigate the interactions in vitro between primary human monocyte-derived macrophages and ceramic scaffolds that have been shown to have varying degrees of success in promoting bone regeneration in vivo Specifically, baghdadite (Ca3ZrSi2O9) and strontium-hardystonite-gahnite (Sr-Ca2ZnSi2O7-ZnAl2O4) scaffolds were chosen as two materials that enhanced bone regeneration in vivo in large defects under load compared with clinically used tricalcium phosphate-hydroxyapatite (TCP-HA)...

BACKGROUND: Temporal bone fractures (TBFs) are harbingers of high energy head trauma that can result in a variety of significant complications of the auditory, vestibular, nervous, and vascular systems. Multiple cohort studies have identified the incidence and proper evaluation of these fractures. We hypothesize that these have changed with the advent of modern high resolution computer tomography (CT) imaging. METHODS: We performed a retrospective review of all TBFs admitted to an urban level one trauma center between June 1, 2011 and May 31, 2015...

In January 2005, the National Institute for Health and Care Excellence (NICE) in England and Wales provided new guidance on the use of antiosteoporosis therapies for the secondary prevention of osteoporotic fractures. This was shortly followed in the same year by market authorization of a generic form of alendronic acid within the UK. We here set out to estimate the actual practice impact of these events among hip fracture patients in terms of antiosteoporosis medication prescribing and subsequent fracture incidence using primary care data (Clinical Practice Research Datalink) from 1999 to 2013...

AIMS: To describe the normal ultrasonographic appearance of the temporomandibular joint (TMJ) in cattle, and to describe the ultrasonographic pathology of the TMJ as assessed in one cow with TMJ disease. METHODS: The TMJ of 12 healthy Holstein-Friesian cows were examined using a portable ultrasonographic unit with a 7.5 MHz linear probe and a 6.0 MHz convex probe. Each TMJ was scanned in a rostrolateral, lateral and caudolateral plane. In addition, the TMJ of one 2-year-old cow with clinical signs of food retention in the mouth, head tilt, swelling and pain in the right TMJ region and an infected horn fracture was examined ultrasonographically...

This study aimed to examine progressive temporal relationships between changes in major reproductive hormones across three waves of a cohort study of older men and (1) changes in bone mineral density (BMD) and (2) incident fractures (any, hip or non-vertebral) over an average of 6 years of follow-up. The CHAMP cohort of men aged 70 years and older were assessed at baseline (2005 to 2007, n = 1705), 2-year follow-up (n = 1367), and 5-year follow-up (n = 958). Serum testosterone (T), dihydrotestosterone (DHT), estradiol (E2), and estrone (E1) (by liquid chromatography-tandem mass spectrometry [LC-MS/MS]), and sex hormone-binding globulin (SHBG), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) (by immunoassay) were measured at all time-points, whereas free testosterone (cFT) was calculated using a well-validated formula...
