Treatment strategies for large oral venous malformations using intralesional laser photocoagulation.

We report two treatment strategies using intralesional laser photocoagulation (ILP) for large venous malformations (VMs) in the oral cavity. ILP is considered to be an effective technique for massive vascular lesion. The satisfactory results could have been obtained, since we started ILP for the treatment of large VMs. Recently, to improve the safety, reliability, and effectiveness of the treatment, we developed modifications of ILP that include a combination of ILP and transmucosal irradiation; and compartmentalization and serial step irradiation. In the former, ILP is performed for a deep layer lesion and transmucosal irradiation with multiple spots fashioned using a single pulse is added for the superficial layer in the same session, to increase the efficacy of regression. In the latter, the lesion is divided by virtual compartment and each area will be sequentially treated by ILP. The irradiated area and total energy in a session should be limited to avoid severe reactions and excessive thermal destruction of surrounding tissue. All treatment outcomes by each technique were satisfactory without serious complications, such as deep ulcer formation, bleeding, or severe swelling developing obstruction. Both treatment strategies improve the safety, reliability, and effectiveness of ILP and make the method less traumatic for patients

Blood Biomarkers in Idiopathic Pulmonary Fibrosis.

PURPOSE: Idiopathic pulmonary fibrosis (IPF) is a progressive and lethal lung disease of unknown origin whose incidence has been increasing over the latest decade partly as a consequence of population ageing. New anti-fibrotic therapy including pirfenidone and nintedanib have now proven efficacy in slowing down the disease. Nevertheless, diagnosis and follow-up of IPF remain challenging. METHODS: This review examines the recent literature on potentially useful blood molecular and cellular biomarkers in IPF. Most of the proposed biomarkers belong to chemokines (IL-8, CCL18), proteases (MMP-1 and MMP-7), and growth factors (IGBPs) families. Circulating T cells and fibrocytes have also gained recent interest in that respect. Up to now, though several interesting candidates are profiling there has not been a single biomarker, which proved to be specific of the disease and predictive of the evolution (decline of pulmonary function test values, risk of acute exacerbation or mortality). CONCLUSION: Large scale multicentric studies are eagerly needed to confirm the utility of these biomarkers
