    A 29-year-old man with advanced hilar cholangiocarcinoma was successfully treated with an extended right lobectomy. The carbohydrate antigen 19-9 (CA19-9) level was elevated to 939 IU/l, and the pathological findings revealed moderately differentiated tubular adenocarcinoma which involved almost the entire thickness of the hepatic duct and the adjacent liver tissue (T3) and which was associated with lymph node metastasis (N1). It was a stage IIB (T3N1M0) tubular adenocarcinoma according to UICC pathological staging. Immunohistochemical examination revealed that Ki-67, cyclin D1, and MMP-7 were positive, and 14-3-3σ and p27 were negative. The pathological and immunohistochemical findings indicated high malignant potential indicating poor prognosis. We administrated the postoperative adjunct gemcitabine combined with S-1 chemotherapy. The patient is alive without recurrence and doing well two years after surgery. We also review other reports of cholangiocarcinoma patients aged less than 30 years

    AbstractINTRODUCTIONIdiopathic thrombocytopenic purpura (ITP) is an autoimmune disease characterized by a low platelet count and normal bone marrow. Patients with ITP undergoing surgery are thought to have increased risk for postoperative complications because of their thrombocytopenia.PRESENTATION OF CASEwe report the case of a 66-year-old woman with ITP who required an emergency operation for acute appendicitis associated with disseminated intravascular coagulation. Preoperative therapy consisted of platelet transfusions only, and intraoperative hemostasis was achieved. Postoperatively, high-dose intravenous immunoglobulin (IVIg) therapy led to an increased, stable, and adequate platelet count and good hemostasis.DISCUSSIONThe outcome of this case suggests that IVIg therapy is not always required for preoperative management of patients with.CONCLUSIONIVIg therapy may be useful for postoperative management after emergency surgery

    Pharmacological and genetic inhibition of translocator protein 18 kDa ameliorated neuroinflammation in murine endotoxemia model

    Sepsis-associated encephalopathy (SAE) is a diffuse brain dysfunction associated with sepsis. The development of an effective strategy for early diagnosis and therapeutic intervention is essential for the prevention of poor prognosis of SAE. Translocator protein 18 kDa (TSPO) is a mitochondrial protein implicated in steroidogenesis and inflammatory responses. Despite accumulating evidence that implicates TSPO in the neuroinflammatory response of the central nervous system, the possible role of TSPO in SAE remains unclear. Aim of this study is to address a role of TSPO in neuroinflammation using mice 24 h after systemic injection of lipopolysaccharide (LPS), which consistently demonstrated microglial activation and behavioral inhibition. Quantitative polymerase chain reaction analysis revealed that hippocampal TSPO expression was induced following the systemic LPS injection, associated with an increase in pro-inflammatory cytokines such as tumor necrosis factor-α and interleukin-1β. Interestingly, pretreatment with the TSPO antagonist, ONO-2952, or germ-line deletion of the TSPO gene exhibited an anti-inflammatory effect with significant suppression of LPS-induced production of those cytokines. These effects demonstrated by the ONO-2952 or TSPO knockout were associated with significant recovery from behavioral inhibition, as shown by improved locomotor activity in the open field analysis. Histological analysis revealed that ONO-2952 pretreatment suppressed the LPS-induced activation of TSPO-expressing microglia in the hippocampus of mice. Collectively, these results suggest that TSPO plays a critical role in the SAE mouse model. Based on this finding, monitoring TSPO activity, as well as the progress of endotoxemia and its sequelae in the animal model, would deepen our understanding of the underlying molecular mechanism of SAE
