Leiomyosarcoma of the Nasal Cavity.

Leiomyosarcoma (LMS) in the sinonasal tract (SNT) is a rarity that has been firstly described in 1958. Since then, there have been only a few articles about this entity. Most of the data available about LMS in the SNT is derived from case reports.

Not All Embolizations Are Created Equally in the Management of Posterior Epistaxis: Discussion of Safety Measures Avoiding Neurological Complications.

Today, there are still no uniform guidelines for the treatment of epistaxis. Furthermore, it is widely debated whether embolization or surgical approaches should be the first choice of treatment for intractable posterior epistaxis after conservative measures have failed. In several meta-analyses, it is reported that endoscopic sphenopalatine artery ligation and embolization have similar success rates, but embolization was associated with more severe neurological complications.

Magnetic resonance T2 mapping and diffusion-weighted imaging for early detection of cystogenesis and response to therapy in a mouse model of polycystic kidney disease.

Polycystic kidney disease (PKD) is among the leading causes of end-stage renal disease. Increasing evidence exists that molecular therapeutic strategies targeted to cyst formation and growth might be more efficacious in early disease stages, highlighting the growing need for sensitive biomarkers. Here we apply quantitative magnetic resonance imaging techniques of T2 mapping and diffusion-weighted imaging in the jck mouse model for PKD using a clinical 3.

Characterization of a splice-site mutation in the tumor suppressor gene FLCN associated with renal cancer.

Background: Renal cell carcinoma is among the most prevalent malignancies. It is generally sporadic. However, genetic studies of rare familial forms have led to the identification of mutations in causative genes such as VHL and FLCN.
