Among diagnostic progress over the last three years in internal medicine, Antisynthetase Syndrome is now more easily recognised with the diffusion of laboratory tests for research of antibodies against tRNA synthetases (Anti JO1, anti PL7, Anti PL12). In two third of cases, these antibodies are found despite absence of antinuclear antibodies. Hence, we have to search them specifically in patients with polyarthritis associated with myositis, cutaneous manifestations (Raynaud phenomenom and "mechanic'hands") and interstitial lung disease. Discovery of asymptomatic mutation in the L ferritin coding sequence help us to better understand the "unexplained" hyperferritinemia. Initially described by japonese gastroenterologists, auto immune pancreatitis in fact a part of a systemic sclerosing disease with a biochemical hallmark: in crease of a subclass of immunoglobulins G (IgG4). A new pediatric disease due to a deficiency of the interleukin1 receptor antagonist (multifocal aseptic osteitis, periostitis, stomatitis, disseminated pustulosis) help us to better understand unexplained auto inflammatory diseases. The therapeutic progress is primarily due to an explosion of biological therapies, particularly four of them very useful for internists (in an off label use) : Interleukin 1 inhibitors (anakinra, Canakinumab) to treat some auto inflammatory diseases (cryopirin associated periodic syndromes and deficency of interleukin 1 receptor antagonist), monoclonal antibody against interleukin 5 (mepolizumab) to treat some hypereosinophilic syndromes and Churg and Strauss angiitis, interleukin 6 inhibitiors to treat multifocal Castleman's disease and adult Still disease, a monoclonal antibody against vascular endothelial growth factor (Bevacizumab) to treat hereditary hemorrhagic telangiectasia.

At present, no effective chemotherapy for pancreatic neuroendocrine carcinoma (PNEC) exists. However, anti-angiogenic therapy is expected to be effective for PNEC, a hypervascular tumor. We treated PNEC and hypovascular pancreatic ductal cell carcinoma (DCC) cell lines with the anti-vascular endothelial growth factor (VEGF) antibody bevacizumab, and compared the antitumor effect between the two different types of cell lines. The PNEC cell line QGP-1 and the DCC cell lines BxPC-3 and AsPC-1 were used. We evaluated the ability of the cell lines to proliferate and secrete VEGF in vitro, the antitumor effect of bevacizumab administration in vivo and the side effects of bevacizumab on the pancreas in a caerulein-induced pancreatitis model. Comparison of the QGP-1 and DCC cell lines showed that QGP-1 secreted a higher level of VEGF under a hypoxic environment than the DCC cell line, and bevacizumab exerted the most marked growth-inhibitory effect on QGP-1; the number of intratumoral blood vessels decreased and the percentage of proliferating cells was approximately the same. In the pancreatitis model, bevacizumab administration did not adversely affect the pancreatitis or the associated hypoxic environment. Bevacizumab does not affect the pancreas itself; therefore, its potent inhibitory effect on the growth of pancreatic neuroendocrine tumors alone can be expected.
