Colorectal cancers (CRCs) often show a dense infiltrate of cytokine-producing immune/inflammatory cells. The exact contribution of each immune cell subset and cytokine in the activation of the intracellular pathways sustaining CRC cell growth is not understood. Herein, we isolate tumor-infiltrating leukocytes (TILs) and lamina propria mononuclear cells(More)
Initially identified as an inhibitor of transforming growth factor (TGF)-β mainly owing to its ability to bind TGF-β receptor type I and abrogate TGF-β-driven signaling, Smad7 can interact with additional intracellular proteins and regulate TGF-β-independent pathways, thus having a key role in the control of neoplastic processes in various organs.(More)
Recurrence of colorectal cancer (CRC) following a potentially curative resection is a challenging clinical problem. Matrix metalloproteinase-7 (MMP-7) is over-expressed by CRC cells and supposed to play a major role in CRC cell diffusion and metastasis. MMP-7 RNA expression was assessed by real-time PCR using specific primers in peritoneal washing fluid(More)
Gastric outlet obstruction as a result of gallstone (Bouveret's syndrome) is a rare but serious complication of cholelithiasis. Although patients present with persistent vomiting, colicky epigastric pain and dehydration, the clinical features of the Bouveret's syndrome are not pathognomonic. Due to its rarity, the diagnosis and treatment represent a(More)
BACKGROUND Vasospastic disorders (acrocyanosis, Raynaud's syndrome, causalgia) can arise from different etiologic factors, but the pathogenesis is always represented by an altered mechanism of vasal motility. Upper dorsal sympathectomy has been demonstrated to be an effective treatment for these disorders by decreasing peripheral resistances. Surgical(More)
Innate lymphoid cells (ILCs) are an emerging family of innate hematopoietic cells producing inflammatory cytokines and involved in the pathogenesis of several immune-mediated diseases. The aim of this study was to characterize the tissue distribution of ILCs in celiac disease (CD), a gluten-driven enteropathy, and analyze their role in gut tissue damage.(More)
INTRODUCTION Obesity is a contributor to the global burden of chronic diseases, including non-alcoholic fatty liver disease and non-alcoholic steatohepatitis (NASH). NASH cirrhosis is becoming a leading indication for liver transplant (LT). Obese transplanted patients have higher morbidity and mortality rates. One strategy, to improve the outcomes in these(More)
Interleukin (IL)-21 triggers inflammatory signals that contribute to the growth of neoplastic cells in mouse models of colitis-associated colorectal cancer (CRC). Because most CRCs are sporadic and arise in the absence of overt inflammation we have investigated the role of IL-21 in these tumors in mouse and man. IL-21 was highly expressed in human sporadic(More)
Midgut malrotation is an anomaly of fetal intestinal rotation. Its incidence in adults is rare. A case of midgut malrotation in a 51-year-old man with complicated Crohn's disease of the terminal ileum is presented. Symptoms, diagnosis, and treatment are reviewed. Preoperative workup led to correct surgical planning that ultimately allowed a successful(More)
Intracranial extradural hematoma is usually traumatic. Rarely, it can occur spontaneously associated with coagulative disorders (spontaneous or iatrogenic), dural vascular malformation, cranio-facial tumors and infections. In these cases, spontaneous extradural hematoma (SEH) is a serious event that needs to be recognized and managed in time to avoid fatal(More)
