since the introduction of engine-driven nickel-titanium (niti) instruments, attempts have been made to minimize or eliminate their inherent defects, increase their surface hardness/flexibility and also improve their resistance to cyclic fatigue and cutting efficiency. the various strategies of enhancing instrument surface include ion implantation, thermal nitridation, cryogenic treatment and el...

Background: Targeted UVB phototherapy currently ranks among the most effective treatment options in localized vitiligo. Purpose: The study aims to assess the efficacy of Targeted NBUVB monotherapy in childhood vitiligo involving less than 10% body surface area. Methods: Thirty-five children with vitiligo, less than 15-years of age were treated with Targeted NBUVB device twice weekly till comple...

objectives: this study evaluated the effect of surface polishing on mercury release from dental amalgam after treatment with 16% carbamide peroxide gel. materials and methods: ninety-six samples from two different amalgam brands were prepared in truncated cone-shaped pvc polymer molds with an external surface area of 195 mm². half of the specimens were polished with green and red rubber, a brus...

Introduction: Megavoltage X-ray beams are used to treat cervix cancer due to their skin-sparing effect. Preferably, the radiation surface doses should be negligible; however, it increases due to electron contamination produced by various field parameters. Therefore, it is essential to provide proper knowledge about the effect of different field parameters on radiation doses. This study sought t...

BACKGROUND Lopinavir/ritonavir is a common protease inhibitor (PI) used for second-line regimens in children. Several studies have shown higher plasma concentrations of antiretroviral agents in Thai adults than in Caucasians, suggesting that lower doses may be used. METHODS An open label study in 24 HIV-infected children between the age of 2 and 18 years, naive to PIs, randomized to receive e...

PURPOSE The aim of this study was to evaluate the efficacy of low-dose oral methotrexate (MTX) as a treatment for patients with Kawasaki disease (KD) which was resistant to intravenous immunoglobulin (IVIG). PATIENTS AND METHODS The patients who had persistent or recrudescent fever after treatment with IVIG were subsequently treated with low-dose oral MTX [10mg/body surface area (BSA)] once w...

BACKGROUND AND PURPOSE Although surgery has been widely accepted as the treatment of choice for stress urinary incontinence (SUI), there has recently been an increased interest in the conservative management of this condition. The aims of this study were to test the ability of a biofeedback-assisted pelvic-floor muscle exercise (PFME) program to affect symptoms of SUI in premenopausal women and...
