Objective To systematically review the association between migraine and rosacea. Background Migraine is a complex disorder with episodes of headache, nausea, photo- and phonophobia. Rosacea is an inflammatory skin condition with flushing, erythema, telangiectasia, papules, and pustules. Both are chronic disorders with exacerbations of symptoms almost exclusively in areas innervated by the trigeminal nerve. Previous studies found an association between these disorders. We review these findings, provide a meta-analysis, and discuss possible pathophysiological commonalities...

OBJECTIVES: Systemic mastocytosis (SM) is characterized by the accumulation of mast cells in tissues other than the skin. Bone involvement although frequent has not been thoroughly evaluated. Primary objective was to determine risk factors associated with fragility fractures (FF) in SM. Secondary objectives were to evaluate the ability of bone marrow tryptase (BMT) level to identify patients with FF, and to describe bone involvement in SM. METHODS: We analyzed retrospectively all consecutive patients seen in our expert center, with a diagnosis of SM according to the 2001 WHO criteria, and with complete bone assessment...

NADPH oxidases (NOX) have many biological roles, but their regulation to control production of potentially toxic ROS molecules remains unclear. A previously identified insertion sequence of 21 residues (called NIS) influences NOX activity, and its predicted flexibility makes it a good candidate for providing a dynamic switch controlling the NOX active site. We constructed NOX2 chimeras in which NIS had been deleted or exchanged with those from other NOXs (NIS1, 3 and 4). All contained functional heme and were expressed normally at the plasma membrane of differentiated PLB-985 cells...

The use of imaging for age-related macular degeneration (AMD) depends on how it benefits clinical management and on reimbursement. The latter should relate to the former. This review assesses how different forms of AMD can be imaged and what information this provides. For nonneovascular AMD high-resolution optical coherence tomography (OCT), autofluorescence, and near infrared imaging can identify the type of drusen, such as reticular pseudodrusen, which influences prognosis, and the amount of atrophy, for which phase 3 trials are underway...

Pulmonary arteriovenous malformation, which is defined as the presence of an ab-normal connection between the pulmonary artery and pulmonary vein, is rarely seen. Although it generally presents as a congenital condition, it may be accompanied by hereditary hemorrhagic telangiectasia. Clinical signs vary according to the amount of shunt in proportion to the number and size of the fistulae. Patients may present with cyanosis and respiratory trouble. If the disease remains untreated, it may result in cardiac failure and ineffective endocarditis, thereby leading to the rupture of the an-eurysmal fistula...

INTRODUCTION: The ataxia telangiectasia syndrome (AT) is a genetic disease with an autosomal recessive inheritance pattern, with multisystem involvement and a broad clinical spectrum. It is caused by the mutation of the ATM gene, causing reduction or absence of the ATM proteinkinase, altering processes in the cell cycle, DNA repair and apoptosis. The objective of this article is to report the case of a patient with ataxia telangiectasia syndrome, caused by a mutation not previously reported in the literature...

Ataxia-telangiectasia is a disorder characterized by cerebellar ataxia, telangiectasia, immunodeficiency, and increased predisposition to cancer susceptibility. Mutations in the ataxia telangiectasia mutated gene seem to play an important role in normal cell function and in cardiovascular remodeling. We report a case of a 14-year-old boy with ataxia-telangiectasia and high-grade B-non-Hodgkin lymphoma who remained in continuous complete remission after chemotherapy and who was admitted into our Emergency Room presenting with episodes of presyncope...

Germline mutations in ATM (encoding the DNA-damage signaling kinase, ataxia-telangiectasia-mutated) increase Familial Pancreatic Cancer (FPC) susceptibility, and ATM somatic mutations have been identified in resected human pancreatic tumors. Here we investigated how Atm contributes to pancreatic cancer by deleting this gene in a murine model of the disease expressing oncogenic Kras (Kras(G12D)). We show that partial or total ATM deficiency cooperates with Kras(G12D) to promote highly metastatic pancreatic cancer...

BACKGROUND Previous studies revealed physiological and pathogenetic similarity between vascular smooth muscles cells with severe pulmonary arterial hypertension and tumors. The DNA damage response was found in both pulmonary arterial hypertension (PAH) cells and tumors. The ataxia-telangiectasia mutated proteins (ATM) pathway is considered an important factor in the DNA damage response of tumor formation, but its function in the development of PAH remains unknown. MATERIAL AND METHODS The Sprague-Dawley rat PAH model was established...

Viruses regulate cellular processes to facilitate viral replication. Manipulation of nuclear proteins and pathways by nuclear replicating viruses often causes cellular genome instability that contributes to transformation. The cellular DNA damage response (DDR) safeguards the host to maintain genome integrity, but DNA tumour viruses can manipulate the DDR to promote viral propagation. In this review, we describe the interactions of DNA tumour viruses with the phosphatidylinositol 3-kinase-like protein kinase (PIKK) pathways, which are central regulatory arms of the DDR...

DNA damaging chemotherapy and radiation are widely used standard-of-care modalities for the treatment of cancer. Nevertheless, the outcome for many patients remains poor and this may be attributed, at least in part, to highly effective DNA repair mechanisms. Ataxia-telangiectasia mutated and Rad3-related (ATR) is a key regulator of the DNA-damage response (DDR) that orchestrates the repair of damaged replication forks. ATR is a serine/threonine protein kinase and ATR kinase inhibitors potentiate chemotherapy and radiation...
