A rare case of carotid body tumor associated with near complete cerebral sinus thrombosis and idiopathic intracranial hypertension. Management strategy and review of the literature.

Background: Carotid body tumors (CBTs) are rare hypervascular lesions with critical location which makes them very challenging to treat. In rare occasions, compression of the jugular vein from the tumor mass could predispose to progressive thrombosis of intracranial venous sinuses. The latter consequently leads to intracranial hypertension (pseudotumor cerebri) with the accompanying danger to the vision.

Unconscious Semantic Priming Influences Performance of Visuomotor Tasks Differently but the Effects are Similar in Young and Older Adults.

We examined the effects of semantic priming of attention on two sequentially presented visuomotor tasks, traffic judgments and saccadic adaptation. Priming was accomplished with the scrambled sentence task: participants formed meaningful sentences from a list of words where a word denoting wide attention focus was involved. The results showed that semantic priming influenced positively saccade adaptation (its' benefit increased) while it attenuated visuomotor performance in the traffic task (RT of hand movements increased).

Recognition of unprovoked (idiopathic) pulmonary embolism-Prospective observational study.

Background: The assessment of the clinical symptoms is the weakest link of the pulmonary embolism (PE) diagnostic algorithm. Despite the presence of highly sensitive and specific imaging methods, verifying PE remains difficult due to nonspecific clinical symptoms and frequently its subclinical course.

Objective: The aim of this study is to improve the recognition of PE by investigating the clinical presentation and short-term prognosis of unprovoked PE in comparison to provoked PE.
