Low accuracy of 1.5 Tesla magnetic resonance imaging in identification of the bony defect in patients with superior semi-circular canal dehiscence syndrome: case-control study.

Objective: To determine the accuracy of 1.5 Tesla magnetic resonance imaging in identifying the bony defect in superior semi-circular canal dehiscence syndrome.

Methods: A retrospective case-control study was conducted in tertiary university settings.

Controlled beat-wave Brillouin scattering in the ionosphere.

Stimulated Brillouin scattering experiments in the ionospheric plasma using a single electromagnetic pump wave have previously been observed to generate an electromagnetic sideband wave, emitted by the plasma, together with an ion- acoustic wave. Here we report results of a controlled, pump and probe beat-wave driven Brillouin scattering experiment, in which an ion-acoustic wave generated by the beating of electromagnetic pump and probe waves, results in electromagnetic sideband waves that are recorded on the ground. The experiment used the EISCAT facility in northern Norway, which has several high power electromagnetic wave transmitters and receivers in the radio frequency range.

Vitamin K Supplementation to Improve Vascular Stiffness in CKD: The K4Kidneys Randomized Controlled Trial.

Background: Vascular calcification, a risk factor for cardiovascular disease, is common among patients with CKD and is an independent contributor to increased vascular stiffness and vascular risk in this patient group. Vitamin K is a cofactor for proteins involved in prevention of vascular calcification. Whether or not vitamin K supplementation could improve arterial stiffness in patients with CKD is unknown.

Study of diffusion weighted MRI as a predictive biomarker of response during radiotherapy for high and ntermediate risk squamous cell cancer of the oropharynx: The MeRInO study.

Introduction And Background: A significant proportion of patients with intermediate and high risk squamous cell cancer of the oropharynx (OPSCC) continue to relapse locally despite radical chemoradiotherapy (CRT). The toxicity of the current combination of intensified dose per fraction radiotherapy and platinum based chemotherapy limits further uniform intensification. If a predictive biomarker for outcomes from CRT can be identified during treatment then individualised and adaptive treatment strategies may be employed.

Hydronephrosis in a pregnant renal transplant patient.

Although pregnancy can cause hydronephrosis in native kidneys, renal transplant dysfunction during pregnancy due to obstruction is rare. A 22-week pregnant renal transplant patient presented with deteriorating renal function (serum creatinine 5.22 mg/dL from 2.
