introduction given the fact that children are more sensitive to radiation, compared to adults, special attention needs to be paid to radiation protection in pediatric radiology. diagnostic reference level (drl) has been defined to be employed as a practical tool for examining the overall performance of a radiological center in terms of patient dose among a series of similar equipments in an are...

background: restless legs syndrome (rls) is a common movement disorder. the occurrence of this syndrome is due to genetic factors and lifestyle. this study performed to determine restless legs syndrome (rls) prevalence in iranian multiple sclerosis (ms) patients and the possible risk factors. methods: this cross‑sectional study was conducted with ms patients, and the age‑ and sex‑matched contro...

introduction. in the current screening system, new admissions are based on general intelligence as measured by universities entrance examination. considering the fact that an important function of medical graduates is to educate the patients how to restore and take care of their health, communicative competence and skills would be, at least, as important as general intelligence. to show that la...

Background: In diagnostic radiology there are two reasons for measuring or estimating radiation doses to patients. Firstly measurements provide a means for setting and checking standards of good practice as an aid to the optimization of patient protection. Secondly estimates of the absorbed dose to tissue and organs in the patients. Materials and Methods: A total of 2382 patients were studied t...

OBJECTIVE To report a case of multiple sclerosis (MS) with delirium as the first presentation. CLINICAL PRESENTATION AND INTERVENTION A 34-year-old female was referred to our department with an acute onset of drowsiness, withdrawal from routine activities and aggression, followed by neurologic deficits after a couple of days. Clinical and radiographic examinations were performed, leading to t...

We present here a combined GC-MS and LC-MS metabolic profiling approach to unraveling the pathological outcomes of aristolochic acid (AA)-induced nephrotoxicity. Urine samples were analyzed by GC-MS and LC-MS in combination with pattern recognition techniques, e.g. principal component analysis (PCA), orthogonal projection to latent structure-discriminant analysis. The work indicates that AA-ind...

The diagnosis of multiple sclerosis (MS) relies on the occurrence of characteristic symptoms, on the patient's history and on the correct interpretation of nowadays very sensitive but not very specific auxillary examinations. This paper reviews the diagnostic criteria and typical signs and symptoms of the disease. The significance of cerebrospinal fluid (CSF) analysis, magnetic resonance imagin...

BACKGROUND Endocardial mapping before sustained monomorphic ventricular tachycardia (SMVT) induction may reduce mapping time during tachycardia and facilitate the ablation of unmappable VT. METHODS AND RESULTS Left ventricular electroanatomic voltage maps obtained during right ventricular apex pacing in 26 patients with chronic myocardial infarction referred for VT ablation were analyzed to i...
