Infliximab induction and maintenance regimens resulted in rapid, substantial, sustained and clinically meaningful improvement in both dermatology-specific and general quality of life indices in patients with psoriasis, with total clearance resulting in maximum improvement.

Deposits of iron and hemosiderosis in the kidney have been observed in diseases with intravascular hemolysis, including paroxysmal nocturnal hemoglobinuria, and valvular heart diseases and prosthetic heart valve implants. However, the decrease in kidney function associated with hemolysis caused by cardiac valvular disease or prostheses is less well recognized. We present a case of intravascular hemolysis after repair and banding of the mitral valve that resulted in massive renal tubular deposition of hemosiderin with decreased kidney function. We discuss the pathophysiologic process of both acute and chronic tubular injury from heme and heme proteins, including injury to organelles resulting in autophagic vacuoles containing damaged organelles, such as mitochondria. We conclude that tubular injury resulting from heme proteins should be considered as a cause of decreased kidney function in all patients with a cardiac valvular disease or prosthesis.

HighlightsParkinson Disease (PD) might involve in white matter degeneration.A PD-facilitated aging effect can be observed in terms of white matter disruption.Splenium of corpus callosum was identified as a pronounced alteration of PD.

BackgroundThe 18F-THK-5351 radiotracer has been used to detect the in vivo tau protein distribution in patients with tauopathy, such as Alzheimer’s disease and corticobasal syndrome. In addition, 18F-THK-5351 can also monitor neuroinflammatory process due to high affinity to astrogliosis. We aimed to explore 18F-THK-5351 distribution patterns and characteristics in patients with recent ischemic stroke.ResultsFifteen patients received 18F-THK-5351 positron emission tomography (PET) and diffusion tensor imaging (DTI) approximately 3 months after ischemic stroke. A region of interest (ROI) was placed in the peri-ischemic area and was mirrored on the contralateral side as the control, and a proportional value was derived from the ratio of the peri-ischemic ROI value over the mirrored ROI value. Increased 18F-THK-5351 retention was observed in the areas around and remote from the stroke location. The proportional 18F-THK-5351 values were negatively correlated with the proportional fractional anisotropy values (r = − 0.39, P = 0.04).Conclusion18F-THK-5351 PET imaging provides a potential tool for in vivo visualization of the widespread ischemia-related changes associated with a microstructural disruption in recent ischemic stroke patients.Electronic supplementary materialThe online version of this article (10.1186/s13550-018-0417-1) contains supplementary material, which is available to authorized users.
