Objective.: Colour Doppler ultrasonography (CDUS) is very important in general vascular diagnostic procedures. Its role in determining the extent of vasculopathy in Systemic Sclerosis (SSc) needs further investigation. The aim of this study was to compare the presence of altered arteries with nailfold capillaroscopy and clinical signs of ischaemia, that is, digital ulcers or pitting scars (DU/PS). A feasible CDUS protocol is provided. Methods.: Two thousand five hundred and twenty-eight arteries of the fingers, palms and wrists from 79 SSc patients (32 arteries per patient) were examined using CDUS...

Objectives.: Salivary cystatin S is a defence protein mainly produced by submandibular glands and involved in innate oral immunity. This study aimed to verify whether cystatin S was diversely expressed in different disease subsets of primary Sjogren's syndrome (pSS) patients, defined on the basis of salivary flow [unstimulated salivary flow rate (USFR)], minor salivary gland (MSG) focus score and submandibular gland ultrasonography abnormalities. We also evaluated miR-126 and miR-335-5p expression in MSG biopsies to verify whether an aberrant regulation of cystatin S at the glandular level may influence its salivary expression...

INTRODUCTION: A rectum balloon implant (RBI) is a new device to spare rectal structures during prostate cancer radiotherapy. The theoretical advantages of a RBI are to reduce the high radiation dose to the anterior rectum wall, the possibility of a post-implant correction, and their predetermined shape with consequent predictable position. OBJECTIVE: To describe, step-by-step, our mini-invasive technique for hands-free transperineal implantation of a RBI before start of radiotherapy treatment...

Congenital extrahepatic portosystemic shunt (Abernethy malformation) is a rare condition characterized by developmental abnormalities of the portal venous system resulting in the diversion of the portal blood from the liver to the systemic venous system through a complete or partial shunt of the portomesenteric blood. We report the case of an 18 year-old female examined for abdominal pain, presenting cholestasis syndrome and an elevated serum aspartate aminotransferase level. Liver ultrasound examination revealed the absence of the portal vein with a complete extrahepatic shunt of the portal blood, multiple focal liver lesions, and multiple associated vascular anomalies...

The objective of this study was to assess the relationship between imaging surrogates for diffuse fibrosis and myocardial dysfunction. Thirty-six New Zealand white rabbits were classified into two groups: a control group (n = 18) and an alloxan-induced diabetes mellitus (DM) group (n = 18). For all rabbits, conventional ultrasonography, two-dimensional speckle tracking, and cardiac magnetic resonance (CMR) T1 mapping were performed; all of the rabbits were then sacrificed for Masson's staining. The extracellular volume (ECV) was calculated from pre- and post-contrast T1 values and compared with myocardial function measured by echocardiography using Pearson's correlation...

REVIEW
Sheng-Chin Kao, Chia-Shiang Lin
Caudal epidural block is a commonly used technique for surgical anesthesia in children and chronic pain management in adults. It is performed by inserting a needle through the sacral hiatus to gain entrance into the sacral epidural space. Using conventional blind technique, the failure rate of caudal epidural block in adults is high even in experienced hands. This high failure rate could be attributed to anatomic variations that make locating sacral hiatus difficult. With the advent of fluoroscopy and ultrasound in guiding needle placement, the success rate of caudal epidural block has been markedly improved...

BACKGROUND: A major model of the cerebral circuits that underpin arithmetic calculation is the triple-code model of numerical processing. This model proposes that the lateralization of mathematical operations is organized across three circuits: a left-hemispheric dominant verbal code; a bilateral magnitude representation of numbers and a bilateral Arabic number code. NEW METHOD: This study simultaneously measured the blood flow of both middle cerebral arteries using functional transcranial Doppler ultrasonography to assess hemispheric specialization during the performance of both language and arithmetic tasks...

Periampullary duodenal diverticula are common and are usually asymptomatic. However, complications like biliary or pancreatic obstruction, duodenal obstruction, perforation, or hemorrhage can occur occasionally. Obstructive jaundice is usually due to biliary stones and periampullary tumors. Rarely, duodenal diverticula may present with obstructive jaundice in the absence of cholelithiasis or other detectable obstacle. This condition is called Lemmel's syndrome. There are only few case reports of this rare condition...

BACKGROUND: Bilateral axillo-breast approach robotic thyroidectomy (BABA RT) is frequently performed and has excellent cosmetic results. However, there has been concern that subcutaneous tunneling in construction of the operation field might interfere with subsequent breast imaging. In this study, we evaluated whether BABA RT interferes with breast imaging by evaluating serial perioperative results of mammography and ultrasonography. METHODS: We selected female patients who underwent BABA RT between 2008 and 2012, and who also had mammography or ultrasonography pre- and postoperatively, and compared the results of pre- and postoperative imaging...
