Objective To investigate the imaging features observed in preoperative Gd-EOB-DTPA-dynamic enhanced MRI and correlated with the presence of microvascular invasion (MVI) in hepatocellular carcinoma (HCC) patients. Methods 66 HCCs in 60 patients with preoperative Gd-EOB-DTPA-dynamic enhanced MRI were retrospectively analyzed. Features including tumor size, signal homogeneity, tumor capsule, tum...

Background and aims. Nano-ionomer (NI) interacts with tooth structures superficially, and there is a concern about the enamel bonding ability of mild self-etch Ketac primer. This study compared the effect of different adhesive procedures (self-etching and etch-and-rinse approach) on long-term marginal microleakage of nano-filled resin-modified glass-ionomer (NI) cervical restorations. Materials...

OBJECTIVE To analyze the prognostic factors related to the recurrence rate of vulvar cancer. METHODS Retrospective study of 87 patients diagnosed of vulvar squamous cell carcinoma diagnosed at a tertiary hospital in Madrid between January 2000 and December 2010. RESULTS The pathological mean tumor size was 35.1±22.8 mm, with stromal invasion of 7.7±6.6 mm. The mean free margin after surgery...

INTRODUCTION Cordectomy by laringofissure and transoral laser surgery has been proposed for the treatment of early glottic cancer. OBJECTIVES The aim of this retrospective study was to evaluate the prognostic value of margin status in 162 consecutive cases of early glottic carcinoma (Tis-T1) treated with CO2 laser endoscopic surgery (Group A) or laryngofissure cordectomy (Group B), and to com...

OBJECTIVE Our goal was to investigate, in a large population of women with ductal carcinoma in situ (DCIS) and long follow-up, the relationship between margin width and recurrence, controlling for other characteristics. BACKGROUND Although DCIS has minimal mortality, recurrence rates after breast-conserving surgery are significant, and half are invasive. Positive margins are associated with i...

Typical bounds on generalization of Support Vector Machines are based on the minimum distance between training examples and the separating hyperplane. There has been some debate as to whether a more robust function of the margin distribution could provide generalization bounds. Freund and Schapire (1998) have shown how a diierent function of the margin distribution can be used to bound the numb...

Fiber-reinforced composite restorations provide excellent esthetics; however, little is known regarding the influence of margin design on marginal accuracy and breaking strength for this type of crown. This study evaluated the effect of variations in tooth preparation design on the marginal accuracy and breaking strength of fiber-reinforced composite crowns. Three metal dies with a total conver...

PURPOSE To measure the MRD (margin reflex distance) in rigid contact lens wearers and controls by a new method, based on computerized image processing. METHOD The patients were selected from the Contact Lens Sector of the Ophthalmology Service at the "Complexo Hospitalar Santa Casa de Porto Alegre", and they were divided into two groups: the first was formed of rigid contact lens wearers (63 ...

M argin loans have long been associated in the popular mind with instability in security markets. Galbraith (1954) placed them at the center of the 1929 Crash, arguing that heavy borrowing from brokers exacerbated the rise in stock prices in the late 1920s and the stock price declines during the Crash. More recently, the analyses of the U.S. Securities and Exchange Commission (1988) and of the ...
