PURPOSE Brachytherapy is a cost-effective method for the management of oral cavity cancers in low to middle income countries. We aimed to evaluate the clinical outcomes of high-dose-rate interstitial brachytherapy (HDR-IBT) in patients with oral cavity cancer. MATERIAL AND METHODS From 2009 to 2013, 78 patients (49 combined external beam radiotherapy [EBRT] plus IBT and 29 IBT monotherapy) wi...

Island biogeography theory (IBT) provides a basic conceptual model for understanding habitat fragmentation. Empirical studies of fragmented landscapes often reveal strong effects of fragment area and isolation on species richness, although other predictions of the theory, such as accelerated species turnover in fragments, have been tested less frequently. As predicted by IBT, biota in fragments...

University of Tehran administers a test known as The University of Tehran English Proficiency Test (the UTEPT) to PhD candidates on a yearly basis. By definition, the test can be considered a high-stakes one. The validity of high stakes tests needs to be known (Roever, 2001). As Mesick (1988) maintains, if the validity of high stakes tests are not known, it might have some undesirable consequen...

Introduction As Rushby (2005) observes, a new constructivist learning paradigm for the various uses of Internet-based technologies (IBT) and environments is emerging. IBT have evolved and been applied to language learning for almost 2 decades. However, research and scholarly discussions that provide a reliable taxonomy of IBT integrated into language curricula that would enable language teacher...

PURPOSE To evaluate the clinical outcome of high-dose-rate (HDR) interstitial brachytherapy (IBT) in patients with oral cavity cancer. MATERIALS AND METHODS Sixteen patients with oral cavity cancer treated with HDR remote-control afterloading brachytherapy using (192)Ir between 2001 and 2013 were analyzed retrospectively. Brachytherapy was administered in 11 patients as the primary treatment ...

Body dysmorphic disorder (BDD) is a debilitating disorder characterized by an excessive pre-occupation with an imagined or very slight defect in one's physical appearance. Despite the overall success of cognitive behavioural therapy (CBT) in treating BDD, some people do not seem to benefit as much from this approach. Those with high overvalued ideation (OVI), for instance, have been shown to no...

Aims The aim of this study was to compare transscleral resection technique performed without hypotensive anaesthesia (TSRWH) with iodine-125 brachytherapy (IBT) in the treatment of choroidal melanoma. Patients and methods This was a retrospective surgical cohort study. Nineteen eyes treated with TSRWH were matched with 53 eyes treated with IBT according to: tumour size, distance to fovea, dista...

OBJECTIVE Transrectal ultrasound (TRUS) has been widely used for guiding prostate implants, but not much for interstitial brachytherapy (IBT) of cervix cancer. The aim of our study is to report our experience with TRUS guided high dose rate (HDR) IBT in patients with carcinoma of uterine cervix. METHODS During the year 2005-2006, 25 patients of cervical cancer not suitable for intracavitary r...
