Blood vessel occlusion with erythrocyte aggregates causes burn injury progression: microvasculature dilation as a possible therapy

Abstract

Other than radiation, caustic strong alkali insults, and massive over-reactive inflammation (pyoderma gangrenosum), injury progression after trauma is usually secondary to ischemia from decreased blood vessel perfusion. Impeded blood flow contributes to injury progression in a variety of disorders including venous stasis ulcers, arterial ulcers, diabetic ulcers, flap and graft necrosis, sickle cell disease, cryoglobulinemia and other vasculopathies, vasculitis, post-myocardial infarction, and post stroke. The cause of impeded blood flow in these disorders/diseases is well known.

Value of the PET/CT 3D Visualization of Head and Neck Squamous Cell Carcinoma extended to Mandible

To study an original 3D visualization of head and neck squamous cell carcinoma extending to the mandible by using [18F]-NaF PET/CT and [18F]-FDG PET/CT imaging along with a new innovative FDG and NaF image analysis using dedicated software. The main interest of the 3D evaluation is to have a better visualization of bone extension in such cancers and that could also avoid unsatisfying surgical treatment later on.

World Health Organization and Its Initiative for Ear and Hearing Care

The World Health Organization (WHO) addresses ear diseases and hearing loss through its program on prevention of deafness and hearing loss. Recently, the World Health Assembly called for action at global and national levels to tackle the rising prevalence and adverse impact of unaddressed hearing loss. Following a public health approach toward this issue, WHO is focusing on i) raising awareness among policymakers and civil society; and ii) providing technical support to countries for promoting hearing care. Meeting this challenge requires a coordinated global effort with all stakeholders working together to make ear and hearing care accessible to all.

Cochlear dead regions: Using the Threshold Equalising Noise (TEN) test to improve the assessment of potential cochlear implant candidates – The Oxford experience

Abstract

The Threshold Equalising Noise (TEN) test can be used to detect cochlear dead regions

Patients with cochlear dead regions may gain limited benefit from conventional amplification

The TEN test can be used to assess selected cochlear implant candidates who do not meet pure tone audiometry criteria for implantation

Our patients with cochlear dead regions had good outcomes following cochlear implantation
