    [Hereditary hemorrhagic telangiectasia and pulmonary arteriovenous malformations in children].
    Rev Med Liege 2016 Dec;71(12):537-540
    Chef de Département de Pédiatrie, CHC Clinique de l'Espérance, 4420 Montegnée, Belgique.
    Hereditary hemorrhagic telangiectasia is a constitutional vascular dysplasia characterized by chronic epistaxis, mucocutaneous and visceral telangiectasias and arteriovenous malformations. Apart from family screenings, the disease is rarely diagnosed during the pediatric age given the late advent of typical clinical symptoms. Nevertheless, arteriovenous malformations are sometimes already present at a young age with significant morbidity risk. Read More


    Bone Morphogenetic Proteins in Vascular Homeostasis and Disease.
    Cold Spring Harb Perspect Biol 2017 Mar 27. Epub 2017 Mar 27.
    Institut National de la Santé et de la Recherche Mécale (INSERM), U1036, 38000 Grenoble, France.
    It is well established that control of vascular morphogenesis and homeostasis is regulated by vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), Delta-like 4 (Dll4), angiopoietin, and ephrin signaling. It has become clear that signaling by bone morphogenetic proteins (BMPs), which have a long history of studies in bone and early heart development, are also essential for regulating vascular function. Indeed, mutations that cause deregulated BMP signaling are linked to two human vascular diseases, hereditary hemorrhagic telangiectasia and pulmonary arterial hypertension. Read More

    TGF-β Signaling in Control of Cardiovascular Function.
    Cold Spring Harb Perspect Biol 2017 Mar 27. Epub 2017 Mar 27.
    Department of Molecular Cell Biology and Cancer Genomics Centre Netherlands, Leiden University Medical Center, 2300 RC Leiden, The Netherlands.
    Genetic studies in animals and humans indicate that gene mutations that functionally perturb transforming growth factor β (TGF-β) signaling are linked to specific hereditary vascular syndromes, including Osler-Rendu-Weber disease or hereditary hemorrhagic telangiectasia and Marfan syndrome. Disturbed TGF-β signaling can also cause nonhereditary disorders like atherosclerosis and cardiac fibrosis. Accordingly, cell culture studies using endothelial cells or smooth muscle cells (SMCs), cultured alone or together in two- or three-dimensional cell culture assays, on plastic or embedded in matrix, have shown that TGF-β has a pivotal effect on endothelial and SMC proliferation, differentiation, migration, tube formation, and sprouting.

It is also known that the interaction between endothelial cells (ECs) and mural cells (MCs) is critical to maintain vessel integrity. However, it has not yet fully been uncovered whether the EC-MC interaction affects BMP9 signaling or not. Read More

    Epistaxis grading in Osler's disease: comparison of comprehensive scores with detailed bleeding diaries.
    Int Forum Allergy Rhinol 2017 Mar 2;7(3):293-299. Epub 2016 Nov 2.
    Department of Otorhinolaryngology, Medical University of Vienna, Vienna, Austria.
    Background: Use of reliable grading scores to measure epistaxis severity in hereditary hemorrhagic telangiectasia (HHT) is essential in clinical routine and for scientific purposes. For practical reasons, visual analog scale (VAS) scoring and the Epistaxis Severity Score (ESS) are widely used. VAS scores are purely subjective, and a potential shortcoming of the ESS is that it is based on self-reported anamnestic bleeding data. Read More

    Oral mucosal changes induced by anticancer targeted therapies and immune checkpoint inhibitors.
    Support Care Cancer 2017 May 22;25(5):1713-1739. Epub 2017 Feb 22.
    Oral Medicine Department, Institut Claudius Regaud, Institut Universitaire du cancer Toulouse-Oncopole, 1 avenue Irène Joliot-Curie, 31059, Toulouse Cedex, France.
    Development of biological targeted therapies and immune checkpoint inhibitors has redefined the treatment for many cancers; however, the increasing use of new protocols has led to physicians observing a new spectrum of toxicities. To date, oral adverse events induced by these new anticancer therapies have been mainly reported using nonspecific terminology ("stomatitis," "mucosal inflammation," "mucositis") and remain poorly characterized, with the exception of mammalian target of rapamycin (mTOR) inhibitor-associated stomatitis. Oral toxicities of targeted therapies often display very characteristic features which clearly differ from classic oral injuries observed with cytotoxic chemotherapy and/or radiotherapy. Read More
