    ABSTRACT: Primary myelofibrosis (PMF) is a clonal hematopoietic stem cell disorder. It is characterized by bone marrow fibrosis, extramedullary hematopoiesis with hepatosplenomegaly and leukoerythroblastosis in the peripheral blood. The main clinical manifestations of PMF are anemia, bleeding, hepatosplenomegaly, fatigue, and fever. Here we report a rare case of PMF with anemia, small bowel obstruction and ascites due to extramedullary hematopoiesis and portal hypertension. The diagnosis was difficult to establish before surgery and the differential diagnosis is discussed.

    ABSTRACT: Screening esophagogastroduodenoscopy (SEGD) is recommended in liver cirrhotic patients while endoscopic variceal ligation (EVL) is used as secondary prophylaxis for esophageal varices. Although sedation is commonly used in gastrointestinal endoscopy, the safety of sedation is unclear for SEGD and EVL in cirrhotic patients. This study was aimed to investigate the safety of combined sedation with propofol plus fentany in cirrhotic patients. This was a retrospective study. A total of 409 patients were involved and divided into sedative SEGD group, sedative EVL group, conscious EVL group and sedative control group. Patients in sedative groups were administrated with propofol and fentany during the endoscopic procedure and minimal hepatic encephalopathy or the sedation-related complications including aspiration, hypoxia, hypotension and bradycardia were evaluated and compared. The satisfactory assessments of endoscopy were evaluated and compared between the sedative EVL group and the conscious EVL group by the gastroenterologists and the cirrhotic patients. The complication rates were not significantly different among the sedative groups: sedative SEGD group (20.5%), sedative EVL group (22.6%) and sedative control group (19.0%). No minimal hepatic encephalopathy was induced in the sedative groups. The satisfactory assessments of sedative EVL group were better than the conscious EVL group evaluated by the gastroenterologists and the cirrhotic patients. The combined sedation with propofol plus fentanyl is safe for EVL as well as SEGD in cirrhotic patients. Sedation might make it easier for gastroenterologists to perform procedures and more acceptable for cirrhotic patients.

    ABSTRACT: To investigate whether tumor necrosis factor-α (TNF-α) mediates ischemia-reperfusion (I/R)-induced intestinal mucosal injury through c-Jun N-terminal kinase (JNK) activation. In this study, intestinal I/R was induced by 60-min occlusion of the superior mesenteric artery in rats followed by 60-min reperfusion, and the rats were pretreated with a TNF-α inhibitor, pentoxifylline, or the TNF-α antibody infliximab. After surgery, part of the intestine was collected for histological analysis. The mucosal layer was harvested for RNA and protein extraction, which were used for further real-time polymerase chain reaction, enzyme-linked immunosorbent assay and Western blotting analyses. The TNF-α expression, intestinal mucosal injury, cell apoptosis, activation of apoptotic protein and JNK signaling pathway were analyzed. I/R significantly enhanced expression of mucosal TNF-α at both the mRNA and protein levels, induced severe mucosal injury and cell apoptosis, activated caspase-9/caspase-3, and activated the JNK signaling pathway. Pretreatment with pentoxifylline markedly downregulated TNF-α at both the mRNA and protein levels, whereas infliximab pretreatment did not affect the expression of TNF-α induced by I/R. However, pretreatment with pentoxifylline or infliximab dramatically suppressed I/R-induced mucosal injury and cell apoptosis and significantly inhibited the activation of caspase-9/3 and JNK signaling. The results indicate there was a TNF-α-mediated JNK activation response to intestinal I/R injury.

    ABSTRACT: Angioimmunoblastic T-cell lymphoma (AITL) is a unique type of peripheral T-cell lymphoma with a constellation of clinical symptoms and signs, including weight loss, fever, chills, anemia, skin rash, hepatosplenomegaly, lymphadenopathy, thrombocytopenia and polyclonal hypergammaglobulinemia. The histological features of AITL are also distinctive. Pure red cell aplasia is a bone marrow failure characterized by progressive normocytic anemia and reticulocytopenia without leucopenia or thrombocytopenia. However, AITL with abdominal pain and pure red cell aplasia has rarely been reported. Here, we report a rare case of AITL-associated pure red cell aplasia with abdominal pain. The diagnosis was verified by a biopsy of the enlarged abdominal lymph nodes with immunohistochemical staining.

    ABSTRACT: Primary natural killer/T-cell (NK/T-cell) lymphoma of the gastrointestinal tract is a very rare disease with a poor prognosis, and the duodenum is quite extraordinary as a primary lesion site. Here, we describe a unique case of a primary duodenal NK/T-cell lymphoma in a 26-year-old man who presented with abdominal pain and weight loss. Abdominal computed tomography scan demonstrated a hypodense tumor in the duodenum. Because of massive upper gastrointestinal tract bleeding during hospitalization, the patient was examined by emergency upper gastrointestinal endoscopy. Under endoscopy, an irregular ulcer with mucosal edema, destruction, necrosis, a hyperplastic nodule and active bleeding was observed on the duodenal posterior wall. Following endoscopic hemostasis, a biopsy was obtained for pathological evaluation. The lesion was subsequently confirmed to be a duodenal NK/T-cell lymphoma. The presenting symptoms of primary duodenal NK-/T-cell lymphoma in this patient were abdominal pain and gastrointestinal bleeding, and endoscopy was important for diagnosis. Despite aggressive treatments, the prognosis was very poor.

    ABSTRACT: Henoch-Schönlein purpura (HSP) is a small-vessel vasculitis mediated by IgA-immune complex deposition. It is characterized by the clinical tetrad of non-thrombocytopenic palpable purpura, abdominal pain, arthritis and renal involvement. The diagnosis of HSP is difficult, especially when abdominal symptoms precede cutaneous lesions. We report a rare case of paroxysmal drastic abdominal pain with gastrointestinal bleeding presented in HSP. The diagnosis was verified by renal damage and the occurrence of purpura.

    ABSTRACT: Multiple endocrine neoplasia type 1 (MEN1), also called Wermer syndrome, is an autosomal dominant disorder characterized by tumors of the parathyroid glands, the anterior pituitary, and the endocrine pancreas. Here, we report a case of MEN1. Our patient was a 44-year-old woman who manifested typical features of MEN1, including insulinoma, pituitary tumors, and parathyroidoma, and exhibited multiple lipomas and a gastrinoma with duodenal ulcers. She was admitted to our hospital because of recurrent massive bleeding of the upper gastrointestinal tract and hypoglycemia. The first operation for pituitary tumors was performed when she was 40 years old. According to these examinations and her clinical course, the patient was diagnosed with insulinoma and gastrinoma. She subsequently underwent surgery for the pancreatic tumors. The majority of these tumor cells were immunohistochemically positive for insulin and negative for glucagon. This case suggests that multiple lipomas, insulinoma and gastrinoma may provide clues for a diagnosis of MEN1.
