background : methadone is considered as a good choice for maintenance treatment program (mmtp) in opioid addicted individuals. qt interval prolongation was reported previously in methadone chronic usersespecially in high dose prescription. qt-interval prolongation predisposes patients to lethal dysrhythmia. this is a report of corrected qt(qtc) prolongation due to acute methadone poisoning. to ...
introduction: esophageal cancer is one of the most frequently occurring cancers in iran and having a high incidence rate among other countries. radiotherapy is one of the three methods (surgery, radiotherapy and chemotherapy) for radical or palliative treatment of esophageal cancer. in this method of treatment, the organs such as heart and spinal cord are regarded as organs at r...
Patient-Specific Radiation Dose and Cancer Risk in Computed Tomography Examinations in Ondo, Nigeria
Introduction: The dose in computed tomography (CT) often approach or exceed the optimum levels, thereby increasing the probability of cancer induction. With wide application of this diagnostic test, it is expedient to determine the effective dose (ED) for each patient to estimate their cancer risk. This study was conducted to investigate the patient-specific dose (PSD) and cancer risk in CT exa...
The aims of this study were to investigate the frequency of computed tomography (CT) examinations for paediatric patients below 15 y of age in 128 CT facilities in 28 developing countries of Africa, Asia and Eastern Europe and to assess the magnitude of CT doses. Radiation dose data were available from 101 CT facilities in 19 countries. The dose assessment was performed in terms of weighted CT ...
Background and purpose: Dose calculations in trachea HDR brachytherapy treatment planning systems are greatly based on TG-43 protocol in which, all materials including air inside trachea are treated the same as water. The aim of this study was to survey the effect of air on dose calculations of Flexiplan treatment planning system in trachea HDR brachytherapy. Materials and methods: To ev...
Antibody-directed, superantigen-induced cytotoxicity has been shown to have potent in vitro and in vivo antitumor effects in preclinical models. In the present study, PNU-214565, a recombinant fusion protein consisting of the Fab of the monoclonal antibody C242 and staphylococcal enterotoxin A (SEA), was used in an escalating repeat dose Phase I clinical trial in patients with advanced gastroin...
The objective of this work was to estimate patient doses (dose-area product, organ dose, effective dose and entrance surface dose) for barium procedures. A total of 175 procedures, in 175 patients, for five different examination categories was analysed. Dose-area product was determined using a transmission ionization chamber. Organ dose and effective dose were assessed using a knowledge of the ...
conclusion despite multiple exposures, ed control is more effective if wss is performed using apmdr in the aec mode. results using apmdr, the mean number of exposures was 6.1 for ap and 6.5 for lat projections. lat projections required more exposures (6.55%) than ap projections. the mean ed was 0.6276 msv (ap) and 0.6716 msv (lat). the mean ed for lat projections was 0.6061 msv in automatic exp...
This is a case report of acute myopia following topiramate administration. There are several reports of this side effect recently and fortunately all of them were reversible. In our case we tried again topiramate with very low dose and increase it very slowly, the patient was followed and she tolerated it well and didnt find ocular problem anymore. So it could be suggested that starting with lo...
