Correlation of sonographic features of invasive ductal mammary carcinoma with age, tumor grade, and hormone-receptor status.

Purpose: To determine whether presenting sonographic features of invasive ductal carcinomas (IDC) are associated with patient age, tumor histologic grade, and hormonal receptor status.

Methods: Sonographic features of 101 consecutive cases of IDC seen at ultrasound were retrospectively assessed based on the BI-RADS criteria of posterior acoustic appearance, tumor margins, and echogenicity. Associations between sonographic features and tumor characteristics were statistically evaluated with attention to patient age.

An overview of renal transplantation: current practice and use of ultrasound.

Imaging has played a major role in monitoring the well-being of the renal graft. Ultrasound, in particular, has been extremely helpful for the detection of postoperative complications related to the transplant kidney. From an imaging perspective, the complications of renal transplantation can be categorized into vascular complications, complications related to the collecting systems (urological complications), perinephric fluid collections, and parenchymal complications.

Can the smallest depth of ascitic fluid on sonograms predict the amount of drainable fluid?

Purpose: To investigate the correlation between the 'smallest fluid depth' (SFD) measured on sonography (US) at the 'paracentesis pocket' with the amount of fluid drained in patients referred for US-guided large-volume paracentesis.

Methods: US examinations performed to guide 60 paracenteses in 29 patients with large-volume ascites were reviewed and the SFD measured at the site of the paracentesis. The SFD was measured from the most superficial bowel loop to the abdominal wall.

Macrophage inflammatory protein-3alpha promotes pancreatic cancer cell invasion.

Background: Human CC chemokine Macrophage Inflammatory Protein-3alpha (MIP-3alpha) directs inflammatory cell migration through its binding to the transmembrane receptor CCR6. MIP-3alpha has recently been shown to promote tumor cell migration in pancreatic adenocarcinoma by up-regulation of matrix metalloproteinases (MMPs). We hypothesized that MIP-3alpha promotes pancreatic cancer invasion through the up-regulation of MMP-9, a Type 4 collagenase.

A case of external carotid artery pseudoaneurysm from hyoid bone fracture.

Carotid artery pseudoaneurysms are detected most commonly after acute traumatic injuries to the head and neck. Pseudoaneurysms of the carotid artery are rare after blunt trauma. The most common site of injury occurs in the internal carotid artery with greater than 70 per cent of those injuries resulting from motor vehicle collisions.
