Eight subjects with carpal tunnel syndrome (CTS) (47.13 ± 7.83 years) and 8 matched controls (46.29 ± 7.27 years) manipulated a test object fitted with an accelerometer and force sensor, both before and after hand muscle fatigue. Grip force and object acceleration were recorded and used to calculate grip force control variables that included Grip Force Peak, Safety Margin, and Time to Grip Forc...
The purpose of this study was to compare two different styles of prostate IGRT: bony landmark (BL) setup vs. fiducial markers (FM) setup. Twenty-nine prostate patients were treated with daily BL setup and 30 patients with daily FM setup. Delivered dose distribution was reconstructed on cone-beam CT (CBCT) acquired once a week immediately after the alignment. Target dose coverage was evaluated b...
OBJECTIVE To identify key factors for predicting positive cone margin and appropriate cone length. METHODS We retrospectively reviewed the margin status of patients who received conization with high grade cervical intraepithelial neoplasia, along with other factors such as patient age, parity, preoperative cytology, size of disease, type of transformation zone, and cone length from patient re...
Background Surgical resection remains the best chance at long-term survival in pancreatic cancer, though margin-positive resections are associated with diminished survival. We examined the effect of margin-positive resection on survival, as well as the role and timing of additional therapies through the National Cancer Database (NCDB). Patients and methods Patients with stage IIA-III pancreat...
IMPORTANCE Positive margins are associated with poor prognosis among patients with oral tongue squamous cell carcinoma (SCC). However, wide variation exists in the margin sampling technique. OBJECTIVE To determine the effect of the margin sampling technique on local recurrence (LR) in patients with stage I or II oral tongue SCC. DESIGN, SETTING, AND PARTICIPANTS A retrospective study was co...
Objective: To evaluate the relationship between Loop Electrosurgical Excision Procedure (LEEP) margin status and subsequent cytology results to determine the significance of margin status as a predictor for recurrent cervical disease. Methods: A retrospective cohort of women who underwent LEEP for treatment of cervical dysplasia from 1995 to 2006 with subsequent follow-up to 2009 at a single ac...
Correlation between Margin Fit and Microleakage in Complete Crowns Cemented with Three Luting Agents
UNLABELLED Microleakage can be related to margin misfit. Also, traditional microleakage techniques are time-consuming. This study evaluated the existence of correlation between in vitro margin fit and a new microleakage technique for complete crowns cemented with 3 different luting agents. Thirty human premolars were prepared for full-coverage crowns with a convergence angle of 6 degrees, chamf...
PURPOSE We evaluated the effect of positive superficial and/or deep margin status on local recurrence (LR) in invasive breast cancer treated with breast-conserving surgery (BCS) followed by radiotherapy. MATERIALS AND METHODS In total, 3,403 stage 1 and 2 invasive breast cancer patients treated with BCS followed by radiotherapy from January 2000 to December 2008 were included in this study. T...
