ABSTRACT

Students' perceptions and feedback have a significant impact on academic progress. The aim of this study was to determine the perceptions of medical students regarding the cumulative effects of the first year general histology course and the sophomore pathology introductory course, in addition to their perceptions regarding the curricular integration of histology and pathology. In this cross-sectional study, a questionnaire was given to second-year and third-year medical students in the middle of second semester. The questionnaire comprised several items on students' attitudes toward anatomic pathology, their feedback on the first year general histology and the sophomore pathology courses, and their perceptions regarding the integration of histology and pathology courses. A five-point Likert scale was used. Data were analyzed using Statistical Package for the Social Science (SPSS) v 20 software. Two hundreds and fourteen of the 236 questionnaires distributed were analyzed (response rate = 90.7 %). More than 51 % of the respondents reported that they couldn't identify the normal tissue counterpart of most practical pathology cases. Only 31.3 % thought their practical histology knowledge was beneficial for them in practical pathology. More than 87 % agreed or strongly agreed that pathology cases need to be copresented with normal tissue examples. A significant proportion of the respondents (60.7 %) were with merging histology and pathology in integrated courses. Pathology was of career choices for only 15.4 % of the participants. The curricular integration of histology and pathology in the first year needs to be tested, and much effort is needed to increase students' affinity for anatomic pathology.


Las percepciones y comentarios de los estudiantes tienen un impacto significativo en el progreso académico. El objetivo de este estudio fue determinar las percepciones de los estudiantes de medicina con respecto a los efectos acumulativos del curso de Histología general de primer año y del curso introductorio de Patología de segundo año, además de sus percepciones con respecto a la integración curricular de Histología y Patología. En este estudio transversal, se entregó un cuestionario a estudiantes de medicina de segundo y tercer año, a mediados del segundo semestre. Asimismo, el cuestionario comprendió varios aspectos referente a la actitud de los estudiantes hacia Patología Anatómica, sus comentarios sobre la Histología general en el primer año y los cursos de Patología de segundo año. Además se incorporaron las percepciones de los estudiantes con respecto a la integración de los cursos de Histología y Patología. Se utilizó una escala de Likert de cinco puntos. Los datos se analizaron utilizando el paquete Statistical Package for Social Science (SPSS) v 20. Se analizaron 214 de los 236 cuestionarios distribuidos (tasa de respuesta = 90,7 %). Más del 51 % de los encuestados indicaron estar de acuerdo o totalmente de acuerdo, en que no lograron identificar el tejido normal, en la mayoría de los casos de Patología práctica. Solo el 31,3 % observó que su conocimiento de Histología práctica era beneficioso para ellos durante la Patología práctica. Más del 87 % estuvo de acuerdo o muy de acuerdo en que los casos de Patología deben ser analizados con muestras de tejido normal. Un grupo importante de los encuestados (60,7 %) consideraba incorporar la Histología y la Patología en cursos integrados. Patología fue de elección en la carrera para el 15,4 % de los participantes. La integración curricular de Histología y Patología en el primer año, debe ser evaluada con el propósito de incrementar la afinidad de los estudiantes con la Patología Anatómica.

ABSTRACT

Background: Silver nanoparticles (SNPs) rapid involvement in industry and nanomedicine increased human exposure to variable forms of these particles, with possible potential risk on human health. Aims: The aim of this study is to investigate the biochemical changes induced by variable sizes of SNPs toxicity. Place and Duration of Study: Faculty of Medicine, The University of Jordan and the College of Applied Medical Sciences at Aljouf University, Saudi Arabia, between January 2013 and January 2014. Study Design: Forty-two male mice were subjected to a daily single dose (1mg/kg body weight) of SNPs using five different sizes (10 nm, 20 nm, 40 nm, 60 nm and 100 nm) for 35 days. Methodology: Biochemical changes of the following eleven biochemical tests were determined: aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, triglycerides, total bilirubin, creatinine, total protein, albumin, urea, uric acid and total cholesterol. Results: Silver nanoparticles significantly elevated aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, triglycerides, total bilirubin and creatinine, with no significant change in total protein level while albumin and total cholesterol levels were lowered. Conclusion: The findings indicate that exposure to SNPs produced significant biochemical changes that might affect the functions of the vital organs. Moreover, these alterations were size-dependent with smaller particles (10 nm and 20 nm) induced more alterations than the larger ones.
