Diffusion MRI anomaly detection in glioma patients.

Diffusion-MRI (dMRI) measures molecular diffusion, which allows to characterize microstructural properties of the human brain. Gliomas strongly alter these microstructural properties. Delineation of brain tumors currently mainly relies on conventional MRI-techniques, which are, however, known to underestimate tumor volumes in diffusely infiltrating glioma.

Parkinson's patients situation during the SARS CoV-2 pandemic and their interest in telemedicine A cross-sectional study.

Background: During the SARS CoV-2 pandemic, telemedicine experienced an enormous boom. Also, for Parkinson's patients there are upcoming alternatives to regular care.

Objective: The aim of the present study was to interview Parkinson's patients under the impression of the first lockdown in Germany about their health care situation, but especially about the use of and attitudes towards videotherapy and -consultation.

The rise and fall of an epizootic of the diphyllobothriidean cestode Schistocephalus pungitii infecting the ninespine stickleback.

Epizootics of diphyllobothriidean cestodes appear to be simple, but deceptive similarity conceals the myriad ways in which these events are shaped by complex abiotic and biotic interactions. In Dog Bone Lake, Alaska, an epizootic of Schistocephalus pungitii infecting the ninespine stickleback (Pungitius pungitius) was short-lived. Its duration, with a peak that lasted only 1 yr, was shorter than for previously documented epizootics in Schistocephalus solidus .

[Valve replacement for aortic regurgitation associated with rheumatoid arthritis: a series of 5 cases].

Between 30 and 50% of patients with rheumatoid arthritis (RA) have cardiac involvement but only 2 to 10% have clinical manifestations. The authors report the results of a retrospective study of 5 cases of aortic regurgitation (AR) requiring valve replacement. There were 4 women and 1 man with an average age of 48.

Recurrent myocardial infarction due to obstruction of the RCA ostium by an aortic papillary fibroelastoma.

A 69-year-old healthy woman was hospitalized twice within a few weeks for management of acute inferior myocardial infarction with thrombolysis and stenting of the right coronary artery (RCA) ostium. After the second myocardial infarction, follow-up angiography showed subocclusion of the proximal RCA, and transesophageal echocardiography and chest computed tomography revealed the presence of a mobile, 2-cm diameter spherical mass partially adherent to the RCA ostium and penetrating the stent. A benign papillary fibroelastoma was surgically excised, the stent was removed, and vein bypass grafting of the RCA was performed.
