ABSTRACT Background: Triple therapy with a proton pump inhibitor, clarithromycin and amoxicillin and quadruple therapy with a proton pump inhibitor, bismuth citrate, metronidazole and amoxicillin have been proposed in Maastricht 2000 as the optimal treatment of Helicobacter pylori infection. We aimed to compare these two regimens in Iranian pediatric patients. Methods: A randomized clinical tr...

We performed preoperative proton beam therapy for locally advanced thymoma and subsequently achieved complete resection. The patient was 31-year old woman, in whom chest computed tomography revealed a huge mass at the left anterior mediastinum. We diagnosed locally advanced type B3 thymoma. Because of the potential for complications to the lung and heart, definitive photon radiation therapy wou...

Proton beam therapy, the most common form of heavy-particle radiation therapy, is not a new invention, but it has gained considerable public attention because of the high cost of installing and operating the rapidly increasing number of treatment centers. This article reviews the physical properties of proton beam therapy and focuses on the up-to-date clinical evidence comparing proton beam the...

PURPOSE The contrast in dose distribution between proton radiotherapy (RT) and intensity-modulated RT (IMRT) is unclear, particularly in regard to critical structures such as the rectum and bladder. METHODS AND MATERIALS Between August and November 2006, the first 10 consecutive patients treated in our Phase II low-risk prostate proton protocol (University of Florida Proton Therapy Institute ...

AIMS To systematically review the efficacy on ulcer healing of 1-week combination of a proton pump inhibitor plus two antibiotics and to perform a meta-analysis of randomized clinical trials to evaluate whether 7 days of proton pump inhibitor-based triple therapy is sufficient to heal peptic ulcer. METHODS Studies where 1-week proton pump inhibitor-based triple therapy was administered to hea...

Proton therapy is an emerging technology for providing radiation therapy to cancer patients. The depth dose distribution of a proton beam makes it a preferable radiation modality as it reduces radiation to the healthy tissue outside the tumor, compared with conventional photon therapy. While theoretically beneficial, its clinical values are still being demonstrated from the increasing number of...

Benefits of Proton Therapy In most cancers requiring radiation therapy, proton therapy can produce better radiation dose distributions with respect to cancer and normal tissue than techniques employing X-rays. A better radiation dose distribution is more important in some clinical situations than others. When considering possible benefits of proton therapy, it is useful to consider the therapeu...
