Introduction Interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. The effect of applicator attenuation is not considered in dose calculation method released by AAPM-TG43. In this study, the effect of High-Dose Rate (HDR) brachytherapy esophageal applicator on dose distribution was surveyed in HDR brachytherapy. Materials and Methods A cylindrical PMMA phan...

Accuracy of treatment planning systems may significantly influence the efficacy of brachytherapy. The purpose of this work is a detailed, varied and independent evaluation of an in-house brachytherapy treatment planning software called STPS. Operational accuracy of STPS was investigated. Geometric tests were performed to validate entry and reconstruction of positional information from scanned o...

PURPOSE To evaluate the effects of rectal enemas on rectal doses during radical high-dose-rate (HDR) intracavitary cervical brachytherapy (BT). MATERIAL AND METHODS Twenty patients suffering from cervical cancer and treated with external beam radiotherapy and HDR-BT were included in a prospective trial. The first brachytherapy fraction was considered the basal status, and patients were instru...

BACKGROUND : Intranasal corticosteroids (INS) are recommended as first-line therapy for allergic rhinitis. To date, no studies have evaluated the impact of an INS delivery system on patient satisfaction. Unless patients use a medication appropriately and consistently, they will not fully benefit from its therapeutic effects. OBJECTIVE : To determine whether the characteristics of the mometaso...

Hyperthermia is the most recent therapy in investigating the biological effects and applications of microwaves for treatment of cancer and tumour. It refers to an artificial heating above 45°C in order to cure cancer. Various antennas like slot antenna, loop antenna, dipole antenna and patch antenna etc. are used as Hyperthermia applicators for damaging and killing cancerous cells from the body...

This article assesses the risks associated with the insertion and removal of contraceptive implants. Risks to patient safety relate to the way the insertion device is designed and used, rather than to the pharmacological properties of the implant itself. Risks associated with removal are not amenable to thoughtful design. A systems approach is taken, the assumption being that human errors are s...
