Radiological features of knee joint synovial chondromatosis
Synovial chondromatosis (SC) is a rare condition with a very variable clinical presentation, thus making the diagnosis not immediate. We report a case of massive primary SC of the knee, properly evaluated with X-rays, ultrasonography and magnetic resonance imaging and successfully treated with an arthroscopic approach
Language re-discovered: A death education intervention in the net between kindergarten, family and territory
The article presents the positive results of a death education experience, realized owing to a collaboration between school, family and territory. The project, with the scope of reflecting on topics of death and spirituality, included 46 children of 5 from kindergarten and 50 parents, and then mobilizing the entire community. Social services and public administration had a special role in this, aiming to guarantee the necessary support for the families in the existential reflections. The experience was monitored with participatory observation, via interviews and questionnaires. The children answered questions regarding death and spirituality during an open and sincere conversation with the teachers. The parents, who at home talked about certain pre-defined teams with the children, were asked to give their informed consent and were given a questionnaire with open questions ex-ante/ ex-post. All data were processed via qualitative analysis of the texts. The results are truly positive, showing that children are capable of facing the problem of death and are able to acquire a certain representation of the spiritual dimension. The parents, who in the beginning demonstrated some anxiety, eventually were greatly satisfied and expressed their willingness to continue to search for the connection between death and transcendence
Targeting a phospho-STAT3-miRNAs pathway improves vesicular hepatic steatosis in an in vitro and in vivo model
Non-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease. Although genetic predisposition and epigenetic factors contribute to the development of NAFLD, our understanding of the molecular mechanism involved in the pathogenesis of the disease is still emerging. Here we investigated a possible role of a microRNAs-STAT3 pathway in the induction of hepatic steatosis. Differentiated HepaRG cells treated with the fatty acid sodium oleate (fatty dHepaRG) recapitulated features of liver vesicular steatosis and activated a cell-autonomous inflammatory response, inducing STAT3-Tyrosine-phosphorylation. With a genome-wide approach (Chromatin Immunoprecipitation Sequencing), many phospho-STAT3 binding sites were identified in fatty dHepaRG cells and several STAT3 and/or NAFLD-regulated microRNAs showed increased expression levels, including miR-21. Innovative CARS (Coherent Anti-Stokes Raman Scattering) microscopy revealed that chemical inhibition of STAT3 activity decreased lipid accumulation and deregulated STAT3-responsive microRNAs, including miR-21, in lipid overloaded dHepaRG cells. We were able to show in vivo that reducing phospho-STAT3-miR-21 levels in C57/BL6 mice liver, by long-term treatment with metformin, protected mice from aging-dependent hepatic vesicular steatosis. Our results identified a microRNAs-phosphoSTAT3 pathway involved in the development of hepatic steatosis, which may represent a molecular marker for both diagnosis and therapeutic targeting
Systemic sclerosis cutaneous expression: Management of skin fibrosis and digital ulcers
Systemic sclerosis is a connective tissue disease with cutaneous involvement. Clinical manifestations result from the balance of inflammations/autoimmunity process and fibrogenesis. Patients suffer from skin ulcers, non-ulcerative lesions including digital pitting scars, telangiectasias, subungual hyperkeratosis, abrasions, fissures, and subcutaneous calcinosis. A review about the pathophysiology of the disease, the physical examination of the patients, the instrumental assessment, and possible treatments is performed
Loss of PALB2 predicts poor prognosis in acute myeloid leukemia and suggests novel therapeutic strategies targeting the DNA repair pathway
Dear Editor,
Acute myeloid leukemia (AML) patients carrying complex karyotype or aneuploidies have a very poor prognosis, with a 5-year overall survival (OS) <20%1. We and others have shown that these patients are characterized by high genomic instability, along with defects of DNA damage response (DDR) genes2,3
