A man with abdominal pain and eosinophilia : tissue is the issue.

A 24-year-old male presented with abdominal pain, postprandial vomiting and weight loss. Lab results showed an elevated serum eosinophil count and CT-scan demonstrated a thickened antral, duodenal and jejunal wall. Repetitive endoscopic mucosal biopsies were normal.

Vascular Complications After Liver Transplantation.

Objectives: Vascular complications after liver transplant can be lethal. High levels of suspicion and aggressive use of diagnostic tools may help with early diagnosis and treatment. Here, we share our experiences regarding this topic.

Anorectal staging: is EUS necessary?

A correct preoperative staging of rectal cancer is important because overall survival and disease-free survival are dependent on TN stage and treatment method. Initially endorectal ultrasound (ERUS) was the mainstay in many institutions for the local staging of all rectal carcinomas. It was more accurate than CT and magnetic resonance imaging (MRI) for the evaluation of local invasion and had a comparable diagnostic accuracy for lymph node involvement.

Belgian consensus on chronic pancreatitis in adults and children: statements on diagnosis and nutritional, medical, and surgical treatment.

Chronic pancreatitis (CP) is an inflammatory disorder characterized by inflammation and fibrosis, resulting in a progressive and irreversible destruction of exocrine and endocrine pancreatic tissue. Clinicians should attempt to classify patients into one of the six etiologic groups according to the TIGARO classification system. MRI/MRCP, if possible with secretin enhancement, is considered the imaging modality of choice for the diagnosis of early-stage disease.

Assessment of tumor vascularization in pancreatic adenocarcinoma using 128-slice perfusion computed tomography imaging.

Objective: Computed tomography (CT) perfusion studies can provide valuable information regarding tumor vascularization. We report on a study assessing CT perfusion characteristics in the normal pancreas and in patients with pancreatic adenocarcinoma.

Methods: Twenty healthy subjects and 20 patients with histologically confirmed pancreatic adenocarcinoma were included in the study after written informed consent and approval by our institutional review board.

A rare infectious complication after endoscopic ultrasound guided fine needle aspiration in an oncological patient and review of the literature.

An endoscopic ultrasound guided fine needle aspiration of a mediastinal lymph node was performed in a cancer patient. Shortly after this procedure, a streptococcus salivarius endocarditis was diagnosed. To our knowledge, this is the first case in the literature of endocarditis following ultrasound guided fine needle aspiration in the absence of cardiac risk factors.

Motion segmentation based on motion/brightness integration and oscillatory correlation.

A segmentation method based on the integration of motion and brightness is proposed for image sequences. The method is composed of two parallel pathways that process motion and brightness, respectively. Inspired by the visual system, the motion pathway has two stages.

Texture segmentation using Gaussian-Markov random fields and neural oscillator networks.

We propose an image segmentation method based on texture analysis. Our method is composed of two parts. The first part determines a novel set of texture features derived from a Gaussian-Markov random fields (GMRF) model.

Gauging effective spatial resolution in multirow helical cardiac computed tomography with a dynamic phantom.

Purpose: To devise a numerical indicator of image quality for multirow helical cardiac computed tomography (CT) and its relation to temporal resolution.

Materials And Methods: A pulsatile cardiac assist device was used to simulate cardiac wall motion by mechanically transmitting the device dynamics to a piece of tungsten wire. Wire motion induced by different device rates was captured with an 8-row subsecond helical CT scanner operating with various scanning parameters.

An oscillatory correlation model of visual motion analysis.

We describe and evaluate a model of motion perception based on the integration of information from two parallel pathways: a motion pathway and a luminance pathway. The motion pathway has two stages. The first stage measures and pools local motion across the input animation sequence and assigns reliability indices to these pooled measurements.

Gallstone recurrence after successful shock wave therapy: the magnitude of the problem and the predictive factors.

Objective: Reports concerning long term recurrence of gallstones after successful extracorporeal shock wave lithotripsy (ESWL) show a high probability of stone recurrence. There is still discussion on the factors influencing stone recurrence. In this study we wanted to evaluate the long term recurrence of gallstones after stone clearance with ESWL and oral bile acids, and to assess possible risk and preventive factors of stone recurrence.

Ultrasound and CT changes of liver parenchyma in acute schistosomiasis.

Acute schistosomiasis in travellers to endemic regions often remains unrecognized. Early diagnosis is important to avoid progression to chronic disease. Diagnosis is based on clinical, epidemiological and laboratory data.

Recurrent pericardial effusion as a result of chronic pancreatitis. Successful treatment with somatostatin.

We report a well-documented case of relapsing chronic calcifying pancreatitis with recurrent pleural and pericardial effusions during episodes of clinical and biochemical relapse of the pancreatitis. Pericardial effusions in association with pancreatitis have been reported only very occasionally, almost exclusively in chronic alcoholic pancreatitis with pseudocyst formation. Our successful conservative treatment consisted of parenteral nutrition and a continuous infusion of somatostatin for 6 weeks.
