Overview of Pulmonary Arteriovenous Malformations and Hereditary Hemorrhagic Telangiectasia

Pulmonary arteriovenous malformations (PAVMs) are rare and commonly caused by an autosomal dominant disorder known as hereditary hemorrhagic telangiectasia (HHT). HHT is an often-missed vascular disorder causing symptoms of epistaxis, mucosal telangiectasia, AVMs, hemoptysis, dyspnea, and iron deficiency anemia. Large AVMs in the lungs, liver, and brain can be life-threatening. Early diagnosis and intervention are imperative to prevent serious complications of massive hemoptysis, stroke, cerebral abscess, and gastrointestinal bleeding.

In this work, a molecular dynamics simulation was conducted to reveal the fine details of self-accommodation microstructure evolution during the phase transformation from austenite to ferrite in pure iron. The growth and shrinkage of ferrite grains with different orientation relationships (ORs) are inter...

In this study, we utilized functional Magnetic Resonance Imaging (fMRI) and dynamic causal modeling (DCM) to characterize the activation of brain areas with a MRI compatible glove actuator compared to the conventional manual therapy. Thirteen healthy volunteers engaged in a motor-visual fMRI task under four different conditions namely active movement, manual passive movement, passive movement using a glove actuator, and crude tactile stimulation. Brain activity following each task clearly identified the somatosensory motor area (SMA) as a major hub orchestrating activity between the primary motor (M1) and sensory (S1) cort...

CONCLUSIONS: The spectrum of neurological complications from dengue virus is broad. There are no reliable data on its real incidence because most of the studies published to date are isolated series or cases. PMID: 31310001 [PubMed - in process]

CONCLUSION: This case reflects the simultaneous presence of air in the arterial and venous circulation of the brain, as well as the peripheral communication through a patent foramen ovale. This production mechanism is poorly documented in the literature. PMID: 31310000 [PubMed - in process]

In this report, we present a series of three cases of snakebites that evolved with hemorrhagic stroke due to delays in the access to antivenom in the Brazilian Amazon, being fundamental for diagnosis to validate the clinical suspicion and make decisions that would improve the treatment and prognosis of the patients.
