INTRODUCTION AND OBJECTIVES: Obesity is an important cardiovascular risk factor and the location of fat deposits seems to be an important determinant of its metabolic impact. Visceral adipose tissue (VAT) exerts a harmful effect on metabolic homeostasis, but few longitudinal studies have evaluated the prognostic impact of the ratio of VAT to subcutaneous adipose tissue (SAT). This study aimed to evaluate whether the VAT/SAT ratio was associated with all-cause mortality and cardiac events...

Patients with unprovoked venous thromboembolism (VTE) may harbor occult cancer. Whether an extensive diagnostic work-up for cancer has additional value over a more limited screening for detection of underlying malignancy in these patients is controversial. We performed a randomized multicenter trial to assess if in patients with unprovoked VTE, a computed tomography (CT)-based diagnostic strategy including thoracic, abdominal, and pelvic CT in combination with fecal occult blood test yields a higher cancer detection rate than a nonstandardized testing approach based on physicians' clinical judgment and patients' preferences...

INTRODUCTION: Liver is the most common site of distant metastasis in colorectal cancer (CRC). Early diagnosis and appropriate treatment selection decides overall prognosis of patients. However, current diagnostic measures were basically imaging but not functional. Circulating tumor cells (CTCs) known as hold the key to understand the biology of metastatic mechanism provide a novel and auxiliary diagnostic strategy for CRC with liver metastasis (CRC-LM). RESULTS: The expression of CD133+ and CD133+CD54+CD44+ cellular subpopulations were higher in the peripheral blood of CRC-LM patients when compared with those without metastasis (P<0...

Metastatic tumors are rare in the breast. Well-differentiated neuroendocrine tumors (WDNETs) are slow-growing neoplasms that arise from neuroendocrine cells, particularly in the gastrointestinal tract and bronchial tree. Metastatic WDNET to the breast is a rare entity. We present a case report of ileal WDNET metastatic to the breast which was initially identified as a small mass in the patient's left breast on screening mammography. Targeted ultrasound identified a suspicious mass, and ultrasound-guided percutaneous core biopsy was performed...

Gallbladder varices are a rare form of collateralization that develop in patients with portal hypertension. We present here a case of gallbladder varices accurately diagnosed by contrast enhanced CT imaging of the abdomen and confirmed by Color Doppler Sonography. A 76-year-old patient with hepatocellular carcinoma developed portal vein thrombosis due to tumor extension during the course of treatment and was incidentally discovered to have gallbladder varices. While most commonly asymptomatic, gallbladder varices are associated with increased risk of massive bleeding, either spontaneously or during cholecystectomy...

A 74-year-old man with IgG4-related cholangitis had been treated with steroids for 1 year. In the outpatient clinic, elevated levels of the tumor marker CA19-9 and serum IgG4 were observed. Abdominal enhanced CT showed a 20mm hypovascular tumor in the pancreatic head. ERCP showed narrowingof the main pancreatic duct in the pancreatic head with slight caudal dilation and stricture of the lower common bile duct. We made a diagnosis of pancreatic cancer, and the patient underwent pancreaticoduodenectomy. Pathological examination of the resected tissue revealed a well-differentiated adenocarcinoma surrounded by autoimmune pancreatitis, characteristic of lymphoplasmacytic sclerosingpancreatitis...

An 81-year-old man underwent total gastrectomy with Roux-en-Y reconstruction for cardiac cancer in our department. He developed high fever on postoperative day 3, and pathological examination showed WBC and CRP level of 12,000/mL and 29.983mg/dL, respectively. A diagnosis of anastomotic leakage was confirmed using enhanced abdominal CT scanning that demonstrated free air around the esophagojejunalanastomosis after totalgastrectomy. The drainage tube was replaced by a 12 Fr sump tube because of leakage on postoperative day 10...

A 63-year-old man was admitted to our hospital owing to weight loss and vertigo. Endoscopic examination revealed advanced gastric cancer type 2. Abdominal CT showed a 62mm liver tumor in segment 4 and a 26mm tumor in segment 8. Distal gastrectomy and D2 lymph node dissection were performed. After surgery, he was administered chemotherapy with S- 1. After 2 courses of treatment, the tumors' in segments 4 and 8 were reduced to 52mm and 16mm, respectively. No other metastases were detected. Left lobectomy and partial resection of segment 8 were performed...

A 44-year-old woman with a history of pulmonary embolism and abdominal echinococcosis complained of sudden thoracic pain and shortness of breath. A D-dimer of 77.5 mg/l (reference ≤0.5 mg/l) was found. Chest CT scan revealed obstruction of the right lower and middle lobe pulmonary artery (PA). Anticoagulation therapy was initiated for the presumed diagnosis of recurrent pulmonary embolism. However, due to persistent symptoms of dyspnea, follow-up CT angiography of the chest was performed 3 months later. A persistent PA obstruction was found and the presumed diagnosis of embolism was questioned...

OBJECTIVES: Conventional imaging methods are excellent for the morphological characterization of the consequences of osteonecrosis; however, only specialized techniques have been considered useful for obtaining functional information. To explore the affinity of radiotracers for severely devascularized bone, a new mouse model of isolated femur implanted in a subcutaneous abdominal pocket was devised. To maintain animal mobility and longevity, the femur was harvested from syngeneic donors...

INTRODUCTION: Non-Hodgkin lymphoma (NHL) can occur at any site of the body, however diffuse and extensive involvement of the peritoneal cavity occurs rarely. Diffuse large B-cell lymphoma (DLBCL) is one of the dominant histological subtypes in extra nodal lymphoma involving the peritoneal cavity while Burkitt lymphoma is seen less commonly. We report two cases of DLBCL and one case of Burkitt lymphoma presenting with peritoneal lymphomatosis (PL). PRESENTATION OF CASE: A retrospective review of two cases involving DLBCL and one case of Burkitt lymphoma with PL was conducted...
