Constitutively active Notch4 receptor elicits brain arteriovenous malformations through enlargement of capillary-like vessels [PDF]

open access: yes, 2014
Arteriovenous (AV) malformation (AVM) is a devastating condition characterized by focal lesions of enlarged, tangled vessels that shunt blood from arteries directly to veins. AVMs can form anywhere in the body and can cause debilitating ischemia and life-

A Retrospective Study of Adult and Pediatric D‐Dimer Tests to Identify Opportunities for Improved Utilization

open access: yesInternational Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction D‐dimers are produced by lysis of cross‐linked fibrin. In children, D‐dimer testing is used to evaluate disseminated intravascular coagulation (DIC) and some inflammatory states, but its use is not validated for screening or ruling out suspected venous thromboembolic events (VTE).

Erythrocyte deformability correlates with microvascular ischemia and disease severity in diabetic retinopathy

open access: yesJournal of Diabetes Investigation, EarlyView.
Under physiological conditions, deformable erythrocytes pass smoothly through the capillary network, maintaining retinal capillary perfusion (A). In pathological conditions, reduced erythrocyte deformability causes irregular passage and stagnation within capillaries, resulting in localized blood flow stasis and microvascular congestion, leading to ...

Selective contralesional constructional hemi‐apraxia after unilateral brain damage: Which relationship with unilateral spatial neglect?

open access: yesJournal of Neuropsychology, EarlyView.
Abstract We describe a peculiar contralesional drawing disorder in three patients affected by focal brain lesions, who did not show signs of unilateral neglect at standard clinical assessment, including the star cancellation test. This picture, that could be termed selective constructional hemi‐apraxia (CHA), could follow both right and left‐hemisphere

KRAS Footprints in the Skin: Leveraging Targeted Therapy for Unresectable Intra‐Cerebral AVM

open access: yesPediatric Dermatology, EarlyView.
ABSTRACT A 15‐year‐old female with a longstanding, unresectable intracerebral arteriovenous malformation (AVM) involving the bilateral thalami and basal ganglia presented with progressive neurologic decline. Given the inaccessibility of the intracranial lesion, a lipomatous scalp nodule overlying the AVM was biopsied for molecular testing and revealed ...
