background: risk of malignancy index (rmi) is the best method for discriminating benign and malignant pelvic masses. the aim of this study was to determine the rmi for preoperative evaluation of pelvic mass. methods: this study was performed on 182 women with adenexal mass referred to yahyahnejiad hospital of babol university of medical sciences in iran from 2007 to 2009.the sensitivity, specif...

BACKGROUND Recent insights provide support for the treatment of cancer during pregnancy, a coincidence that poses both mother and fetus at risk. Our aim was to critically review studies on the physiologic variations during pregnancy, the most common tumor markers used in diagnosis and follow-up of gynecological cancers. METHODS We conducted a systematic review of six tumor markers during norm...

We develop and analyze a class of maximum bound preserving schemes for approximately solving Allen–Cahn equations. apply kth-order single-step scheme in time (where the nonlinear term is linearized by multi-step extrapolation), lumped mass finite element method space with piecewise rth-order polynomials Gauss–Lobatto quadrature. At each level, cut-off post-processing proposed to eliminate extra...

QUESTION UNDER STUDY Repetitive skin trauma and reduced pressure pain sensation are necessary components of plantar ulcer risk in patients with diabetic neuropathy. The diagnostic value of measuring pressure nociception to detect ulcer risk is, however, unknown. Instead, measuring the vibration perception threshold (VPT) by 64 Hz graduated Rydel-Seiffer tuning fork has become standard clinical ...

BACKGROUND Several researchers have determined the tumor length to be an important prognostic indictor of esophageal cancer (EC). However, controversy exists concerning the optimal cut-off points for tumor length to predict overall survival. The aim of this study was to determine the prognostic value of tumor length and propose the optimum cut-off point for tumor length in predicting survival d...

BACKGROUND We assessed the diagnostic accuracy of Determine TB-LAM (LF-LAM) to screen for tuberculosis among ambulatory adults established in HIV care in South Africa. METHODS A systematic sample of adults attending for HIV care, regardless of symptomatology, were enrolled in the XPHACTOR study, which tested a novel algorithm for prioritising investigation with Xpert MTB/RIF. In this substudy...

Distinguishing productive zones of a drilled oil well plays a very important role for petroleum engineers to decide where to perforate to produce oil. Conventionally, net pay zones are determined by applying a set of cut-offs on perophysical logs. As a result, the conventional method finds productive intervals crisply. In this investigation, a net index value is proposed, then; diffusivity equa...
