Radiological imaging is an important part of today’s overall healthcare practicum, Imaging can begin as early as the first day of life but as children are more sensitive to radiation than adults special care should be in place. The main aim of the current study was to determine Entrance Surface Dose (ESD) to pediatric patients as the result of imaging procedure, in main pediatric hospital in Ta...

INTRODUCTION X-ray examinations are commonly used in health care and, in most developed countries, they represent the largest man-made source of radiation exposure for the population. The need for standardization of radiation exposures has been suggested and the guidance levels for various radiographic and radioisotope examinations has been proposed by the International Atomic Energy Agency (IA...

Introduction High doses of ionizing radiation can lead to adverse health outcomes such as cancer induction in humans. Although the consequences are less evident at very low radiation doses, the associated risks are of societal importance. This study aimed at assessing entrance skin doses (ESDs) in patients undergoing selected diagnostic X-ray examinations at public hospitals of Akwa Ibom State,...

Background Given the fact that children are more sensitive to ionizing radiation than adults, with an increased risk of developing radiation-induced cancer, special care should be taken when they undergo X-ray examinations. The main aim of the current study was to determine Entrance Surface Dose (ESD) to pediatric patients arising from routine x-ray examination in the Radiology Department of Ji...

PURPOSE Of all transforms of an eye, aberrations are significant when higher visual acuity is to be achieved. Ray tracing aberrometry developed by the Institute of Biomedical Engineering (Kiev) and first tested at the Vardinoyannion Eye Institute of Crete is a promising technique for eye refraction aberration and refraction mapping. METHODS The technique uses measurement of the position of a ...

1603 Binaural recordings enable us to capture all sound attributes including spatial information, room effect, and source characteristics in a given environment. It has been shown that blocked-entrance binaural recordings provide advantages over open-entrance recordings, primarily because the blocked-entrance recordings are not influenced by the ear canal acoustics of the individual. However, b...

BACKGROUND Cheating on examinations in academic institutions is a worldwide issue. When cheating occurs in medical schools, it has serious consequences for human life, social values, and the economy. This study was conducted to determine the prevalence of cheating and identify factors that influence cheating among students of Hawassa University College of medicine and health science. METHODS ...

Results of radioimmunological and mass-spectrometric tests for morphine in human hair samples, conducted independently in two separate laboratories, were compared. A large degree of qualitative and quantitative parity was observed for the two methods at morphine levels above 1000 micrograms/kg. Due to the variation of results at levels below 1000 micrograms/kg, more GC-MS tests are necessary as...

OBJECTIVE The improved availability of MRI in medicine has led to an increase in incidental findings. Unexpected brain MRI findings suggestive of multiple sclerosis (MS) without typical symptoms of MS were recently defined as radiologically isolated syndrome (RIS). The prevalence of RIS is uncertain. The aim of this study was to determine the prevalence of RIS at a university hospital in a regi...
