PURPOSE To investigate correlation between ocular Demodex infestation and serum. DESIGN A prospective study to correlate clinical findings with laboratory data. PARTICIPANTS We consecutively enrolled 59 patients: 34 men and 25 women with a mean age of 60.4+/-17.6 years (range, 17-93). METHODS Demodex counting was performed based on lash sampling. Serum immunoreactivity to two 62-kDa and 8...

OBJECTIVES/HYPOTHESIS The impact of margin status on the outcomes of early glottic cancer after endoscopic resection is controversial; second look laryngoscopy has shown a low rate of residual cancer, even in margin positive patients. Intraoperative frozen section analysis has been suggested as an alternative to routine second look procedures. The aim of this study was to evaluate and search fo...

This study aimed to determine the efficacy of intraoperative ultrasonography-guided wire localization guided breast-conserving surgery (BCS) for nonpalpable breast cancer and compare it to conventional preoperative wire localization (PWL) guided surgery.We retrospectively analyzed the medical charts of 214 consecutive nonpalpable breast cancer patients who underwent BCS using intraoperative ult...

The management of positive resection margins in micro-endoscopic glottic laser surgery remains a controversial and critical point. This study aims to assess the impact of margin status after transoral laser surgery on local control, survival and organ preservation rates; the decision- making process and treatment options in cases with positive margins are also discussed. We retrospectively revi...

Introduction. Breast conserving surgery (BCS) requires tumor excision with negative margins. Reexcision rates of 30-50% are reported. Ultrasound localization, intraoperative margin pathology, and specimen mammography have reduced reexcisions, but require new equipment. Cavity shave margin (CSM) is a technique, utilizing existing equipment, that potentially reduces reexcision. This study evaluat...

Mantle seismic structure beneath the United States spanning from the active western plate margin to the passive eastern margin was imaged with teleseismic P and S wave traveltime tomography including USArray data up to May 2014. To mitigate artifacts from crustal structure 5–40 s, Rayleigh wave phase velocities were used to create a 3-D starting model. Major features of the final P and Smodels ...

This brief presents a new contribution in the problem of computing the stability margin of two-dimensional (2-D) discrete systems. The method, using the “resultant technique” instead of a typical minimization procedure , is actually an improvement of the method of .

I this paper, we investigate the integrated information and pricing strategy for a seller who can take customer preorders before the release of a product. The preorder option enables the seller to sell a product at an early stage when consumers are less certain about their valuations. We find that the optimal pricing strategy may be highly dependent on the amount of information available at pre...

Purpose This study aimed to evaluate the clinical significance of microscopic invasion to determine the adequate resection margin in early gastric cancer (EGC). Materials and Methods A retrospective review was performed that included patients who underwent gastrectomy for clinical early gastric cancer (cEGC) at Seoul National University Hospital between January 2007 and December 2010. After s...

Abstract Background The present systematic review aimed to summarise the available evidence on indications and oncological outcomes after MA IRE for stage III pancreatic cancer (PC). Methods A literature search was performed in Pubmed, MEDLINE, EMBASE, SCOPUS databases using PRISMA framework identify all studies. Results Nine studies with 235 locally advanced (LA) (82%, 192/235) or Borderline r...
