ABSTRACT
Objectives: This study aimed to assess the knowledge of medical students in ionizing radiation and to study the effect of a 3-hour lecture in correcting their misconceptions
Methods: a cohort study was conducted on medical students at Almaarefa Colleges, Riyadh, Kingdom of Saudi Arabia during the academic year 2015-2016. A 7-question multiple choice test type questionnaires administered before and after a 3-hour lecture was used to assess their knowledge. The data were collected from December 2015 to February 2016. The lecture was given to 333 [72%] participants, out of the total of 459 medical students. It covered topics in ionizing radiation and radiation protection. The questionnaire was validated and analyzed by 3 content experts
Results: of the 333 who attended the lecture, only 253 [76%] students completed the pre- and post questionnaire and they were included in this study. The average student score improved from 47-78% representing a gain of 31% in knowledge [p =0.01]
Conclusion: the results indicated that the medical student's knowledge regarding ionizing radiation and radiation protection is inadequate. Additional lectures in radiation protection significantly improved their knowledge of the topic and correct their current misunderstanding. This study had shown that even with one dedicated lecture, students can learn and learn general principles regarding ionizing radiation
ABSTRACT
Background: anemia in pregnancy is a common problem. Easy diagnosis and treatment enhance focus on anemia cases
Aim and Objectives: to determine the common types and grades of anemia in a hospital lab in Riyadh and to compare types of anemia among age and pregnancy status
Method: cross-sectional study. Study area: a hematology-log in lab
Samples: convenience samples of 120 anemic ladies
Tool: questionnaires. Methods of data collection: CBC results
Results: This study-addressing anemia among women in a lab in Riyadh involves 120 ladies. When they were distributed as pregnant and non-pregnant women, 70% were pregnant. About 70% of the pregnant and 39% of non-pregnant had iron deficiency anemia, this difference statistically significance (P= 0.0013). Normocytic normochromic anemia was falling in 26% and 50% of the pregnant and non-pregnant ladies respectively; this difference was statistically significant (P= 0.0112). About 94.5% of iron deficiency anemias have low MCH. PCV was low in all cases of anemia
Conclusion: Anemia in women of child bearing age are more commonly observed in study. Most common type of anemia among cases was iron deficiency anemia. Iron deficiency anemia was the most common in pregnant, while normochromic normocytic anemia was the most common in non-pregnant. MCV and MCH were significant characteristics finding in iron deficiency anemia
