objective: acute inflammatory demyelinating peripheral neuropathy (guillain-barre-syndrome) is by far the most common cause of immune-medicated peripheral nervous system disease in children; with the near disappearance of poliomyelitis, gbs is responsible for the great majority of cases of acute flaccid paralysis. so far, in several controlled studies, corticosteroids, plasmapheresis and ivig h...

background: x-ray computed tomography (ct) examinations deliver a significant amount of radiation doses to patients comparing to conventional radiography examinations. the objective of the current study was to analyze and investigate the average patient received dose from axial and spiral ct exams in a medical imaging center. material and methods: in this study, the patient imaging technique, w...

background: the equivalent dose in the human body due to the natural gamma-emitting radionucides (238u, 232th and 40k) in the surface soil surrounding the consolidated tin mine site in bukuru-jos, nigeria has been determined in this study. materials and methods: measurements of the soil natural radioactivity were made using a multi-channel pulseheight analyzer (canberra series 10 plus) coupled ...

background: activity concentrations of 40k, 226ra and 228ra were measured in some sachet drinking water samples produced in nigeria. materials and methods: the measurement was done by using high-purity germanium (hpge) detector (canberra industries inc.). the measured activity concentrations for 226ra (u-series) and 228ra (thseries) were used with their ingested dose conversion factors to estim...

background marketing new radiography devices necessitates documenting their absorbed x-ray doses. since the current literature lacks studies on new devices, we assessed the doses of two new devices that had not previously been assessed. objectives the new devices were compared to the promax three dimensional (3d) scanner at two fields of view (fov) in nine critical head and neck tissues and org...

background: this study was performed to compare the effects of low dose interferon beta-1 (ifn-β-1) (cinnovex, 30 mcg) and high dose ifn-β-1 (rebif, 44 mcg) on the reduction of the number and size of plaques in magnetic resonance imaging (mri) in patients with multiple sclerosis (ms). methods: this historical cohort study, which was performed in 2014 in sanandaj (western part of iran). 43 ms pa...

asthma affects an estimated 300 million people worldwide. poor compliance with the prescribed medication leads to increased mortality and morbidity. various determinants of compliance have been described. the purpose of this study was to determine factors that can influence patients' compliance with prescribed metered dose inhaler drugs. 179 patients with diagnosis of asthma were selected from ...

high-dose extended-interval dosage (hded) regimen of aminoglycosides is now considered as the standard dosage strategy in sepsis. although safety and efficacy of this dosing regimen is well studied, but new experiments show increased the risk of resistance development associated with %t>mic less than 60% of the dosing interval following extended interval dosing. moreover, limited information is...

background: the aim of this study was to measure137cs levels in soil and brick samples to set the baseline data and an indicator of fallout radioactivity for this part of the world. this study will help to probe, if there is any health threat posed by 137cs exposure to the residents of the area. materials and methods: twenty five samples of soil and 6 samples of bricks were collected from diffe...
