Dendritic cells （DCs） comprise two functionally distinct subsets： plasmacytoid DCs （pDCs） and myeloid DCs （mDCs）. pDCs are specialized in rapid and massive se- cretion of type I interferon （IFN-I） in response to nucleic acids through Toll like receptor （TLR）-7 or TLR-9. In this report, we characterized a CD56^＋ DC population that express typical pDC markers including CD123 and BDCA2 but produce much less IFN-I comparing with pDCs. In addition, CD56^＋ DCs cluster together with mDCs but not pDCs by genome-wide transcriptional profiling. Accordingly, CD56^＋ DCs functionally resemble mDCs by producing IL-12 upon TLR4 stimulation and priming naive T cells without prior activation. These data suggest that the CD56^＋ DCs represent a novel mDC subset mixed with some pDC features. A CD4^＋CD56^＋ hematological malignancy was classified as blastic plasmacytoid dendritic cell neoplasm （BPDCN） due to its expression of characteristic molecules of ***, we demonstrated that BPDCN is closer to CD56^＋ DCs than pDCs by global gene-expression pro- filing. Thus, we propose that the CD4^＋CD56^＋ neoplasm may be a tumor counterpart of CD56^＋ mDCs but not pDCs.

Endoscopic ultrasonography for evaluating patients with recurrent pancreatitis

引用

World Journal of Gastroenterology 2008年第7期14卷 1016-1022页

作者： Maria Chiara Petrone paolo G Arcidiacono pier Alberto Testoni Division of Gastroenterology & Gastrointestinal Endoscopy Vita-Salute San Raffaele University Scientific Institute San RaffaeleMillanItaly

Acute recurrent pancreatitis (ARP) is still a complex diagnostic and therapeutic challenge in clinical practice. In up to 30% of cases of ARP, it is not possible to establish the etiology of the disease. In the other 70%, many factors play an etiological role in ARP: microlithiasis, sphincter of Oddi dysfunction (SOD), pancreas divisum, hereditary pancreatitis, cystic fibrosis, a choledochocele, annular pancreas, an anomalous pancreatobiliary junction, pancreatic tumors or chronic pancreatitis are diagnosed. EUS should be useful in ARP as it is sensitive for diagnosing bile duct stones, gallbladder sludge, pancreatic lesions, ductal abnormalities and chronic pancreatitis. Endoscopic ultrasound (EUS) appears to be diagnostic in the majority of patients with previously unexplained pancreatitis, and offers an alternative to endoscopic retrograde cholangiopancreatography (ERCP) as the initial diagnostic test in patients with ARP.

Multiple giant diverticula of the foregut causing upper gastrointestinal obstruction

Small bowel diverticulosis represents an uncommon disorder (except for Meckel diverticulum) often misdiagnosed since it causes non-specific gastroin- testinal symptoms. Most of times the diagnosis is carried out in case of related complications, such as diverticulitis, hemorrhage, perforation or obstruction. Intestinal obstruction can be caused by inflammatory stenosis due to repeated episodes of diverticulitis, volvulus, intussusception or jejunal stones. Herein we report a case of multiple jejunal diverticula causing chronic gastrointestinal obstruction.
