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...

Introduction: Intraoperative electron radiotherapy (IOERT) is an IORT technique in which electron beams with different nominal energies are used for irradiation of microscopic residual of tumor bed after surgery. Application of a shielding disk, which is positioned under the target volume, for protecting the normal tissues such as pectoral muscle, lung, and heart is one of the a...

PURPOSE Radiotherapy (RT) has played a significant role in treating non melanoma skin cancer (NMSC). High-dose-rate brachytherapy (HDR-BT) approaches have a paramount relevance due to their adaptability, patient protection, and variable dose fractionation schedules. Several innovative applicators have been introduced to the brachytherapy community. The Valencia applicator is a new superficial d...

PURPOSE T2 magnetic resonance imaging (MRI) is recommended as the imaging modality for image-guided brachytherapy. In locally advanced cervical carcinoma, combined endocavitary and interstitial applicators are appropriate (Vienna or Utrecht). To cover extensive disease, Template Benidorm (TB) was developed. Treatment planning system applicator libraries are currently unavailable for the Utrecht...

The main purpose of this article is a complex hyperthermia applicator system design for treatment of head and neck region. The applicator system is composed of four waveguides with a stripline horn aperture and circular water bolus. The specific absorption rate (SAR) and temperature distribution from this applicator in various numerical phantom models was investigated. For used targets, the tre...

In the field of microwave hyperthermia, the use of minimally invasive applicators is recognized as a very promising technique for the treatment of small tumours because a very thin applicator can be easily introduced inside the body and precisely localized using the most advanced 3D imaging techniques and surgical robots. Minimally invasive hyperthermic applicators (MIHA) have been successfully...
