CONCLUSION: CBCT allows a precise evaluation of the dimensions and of the shape of the cochlear duct that is of primary importance for the choice of the length and the design of the electrode array. This radio-histological study confirms that CBCT is a reliable tool to be used in clinical studies to evaluate the position of straight electrode arrays within the cochlear scala. OBJECTIVE: To validate the reliability of cone beam computed tomography (CBCT) in the evaluation of cochlear anatomy and positioning of a straight electrode array, by comparing radiological images to histological analysis of cochlear implanted temporal bones...

OBJECTIVE: Ischemia-reperfusion (IR) is a limb- and life-threatening complication of acute limb ischemia and musculoskeletal trauma. Carbon monoxide-releasing molecules (CORMs) have recently been shown to protect microvascular perfusion and to reduce inflammation and injury in various ischemic animal models. The purpose of this study was to examine the effects of water-soluble CORM-3 on the extent of IR-induced muscle injury. METHODS: Wistar rats were randomized into three groups: sham (no ischemia), IR + CORM-3 (10 mg/kg intraperitoneally), and IR + inactive CORM-3 (iCORM-3; 10 mg/kg intraperitoneally)...

An inflammatory tissue reaction around the electrode array of a cochlear implant (CI) is common, in particular at the electrode insertion region (cochleostomy) where mechanical trauma often occurs. However, the factors determining the amount and causes of fibrous reaction surrounding the stimulating electrode, especially medially near the perimodiolar location, are unclear. Temporal bone (TB) specimens from patients who had undergone cochlear implantation during life with either Advanced Bionics (AB) Clarion (TM) or HiRes90K(TM) (Sylmar, CA, USA) devices that have a half-band and a pre-curved electrode, or Cochlear (TM) Nucleus (Sydney, Australia) device that have a full-band and a straight electrode were evaluated...

Neurological injury develops over days following cardiac arrest (CA); however, the exact mechanisms remain unknown. After stroke or trauma, the progression of neurological injury is associated with cortical-spreading depolarizations (CSDs). The objective was to investigate whether CA and subsequent resuscitation in rats are associated with 1) the development of spontaneous negative direct current (DC) shifts indicative of CSDs, and 2) changes in artificially induced CSDs in the postresuscitation period. Male Sprague-Dawley rats were randomized into four groups: 1) CA 90, 2) Control 90, 3) CA 360, and 4) Control 360...

BACKGROUND: Optic tract dysfunction may be the predominant or only clinical manifestation of an intracranial disorder including mass legion, ischemic infarct, inflammatory disease, and trauma. Documentation of the neuroimaging features of these lesions is limited to reports mostly published before the availability of MRI. This study was undertaken to document the spectrum of MRI features in patients presenting with optic tract dysfunction. METHODS: A retrospective study from 2004 to 2015 at a single tertiary care neuro-ophthalmology service of 24 patients who had unilateral optic tract dysfunction defined by a homonymous hemianopia and a relative afferent pupil defect that could not be attributed to optic neuropathy or retinopathy...

The biological transition metals iron (Fe), copper (Cu) and zinc (Zn) are thought to contribute to the neuronal pathologies that occur following traumatic brain injury (TBI), and indeed our previously published work in young (3 month-old) mice clearly demonstrates a significant spatiotemporal modulation of metals following TBI. Of note, however, is the literature observation that there is both an apparent detrimental effect of aging on TBI outcomes and an alteration in metals and their various transporters with normal advancing age...

Spinal trauma is a devastating event with a high morbidity and mortality. The rationale of imaging is to diagnose the traumatic abnormalities and characterize the type of injury, to estimate the severity of the lesions, to evaluate the potential spinal instability. In case of spinal instability, the goals of operative treatment are decompression of the spinal cord canal and stabilization of the disrupted vertebral column. Particularly, diagnostic imaging, mainly by CT and MR, has a main role in the post-treatment evaluation...

PURPOSE: Inflammatory changes are suspected in the pathophysiology of arthrofibrosis formation and require early molecular examination.Here, we assessed the hypothesis that early inflammatory genes are related to arthrofibrosis by ascertaining gene expression during the early stages of contracture genesis in an animal model. METHODS: Joint trauma was incited surgically in a cohort of rabbits (n=36) knees followed by immobilization in a model of contracture.Six groups of 6 rabbits were sacrificed at multiple time points (0, 6, 12, 24, 72h and 2weeks)...

Non-traumatic cardiac arrest is a major public health problem that carries an extremely high mortality rate. If we hope to increase the survivability of this condition, it is imperative that alternative methods of treatment are given due consideration. Balloon occlusion of the aorta can be used as a method of circulatory support in the critically ill patient. Intra-aortic balloon pumps have been used to temporize patients in cardiogenic shock for decades. More recently, resuscitative endovascular balloon occlusion of the aorta (REBOA) has been utilized in the patient in hemorrhagic shock or cardiac arrest secondary to trauma...

Patients suffering from abducent nerve palsy are usually primary seen by a conservative medical Specialist. In most cases the ENT specialist is secondary involved for treatment. In the majority of cases abducent nerve palsy is a temporary symptom associated with neurologic or vascular diseases. Rarely inflammation, neoplasm or fracture of the skull base cause this symptom and lead to an intervention done by the ENT surgeon. This case series describes retrospectively the abducent palsy seen through the eyes of an ENT surgeon...

Chronic traumatic encephalopathy (CTE) is a neurodegenerative tauopathy associated with repetitive mild brain trauma. CTE, previously termed "dementia pugilistica," has been identified in American football, ice hockey, baseball, rugby and soccer players, boxers, wrestlers, and military personnel exposed to blast and other traumatic brain injuries. There is often a long latency period between an individual's exposure to repetitive brain trauma and the clinical symptoms of CTE. The pathology of CTE is characterized by a progression from isolated focal perivascular hyperphosphorylated tau lesions in the cerebral cortex to a widespread tauopathy that involves diffuse cortical and medial temporal lobe regions...

Brain abscess is a focal pyogenic infection of the brain's parenchyma. The most frequent intracranial locations (in descending order of frequency) are: frontal-temporal, frontal-parietal, partial, cerebellar, and occipital lobes. The major predisposing factors are: an associated contiguous focus of infection, trauma, and hematogenous spread from a distant focus. The microbial etiology depends on the site of the primary infection; the patient's age, underlying condition, and immune status; and the geographic location...
