Ergonomics is the scientific study of people and their working environment. Dentistry is a profession that generally produces various musculoskeletal disorders. If ergonomic principles are applied in the field of dentistry, it helps to prevent occupational ergonomic health hazards and provides more comfort to the dentist and patient. To assess knowledge, attitudes, and practice of ergonomics during routine dental procedures among undergraduates of Faculty of Dentistry, Tanta University, cross-sectional study was conducted among dental students of Tanta University during the year 2015-2016 using a predesigned selfadministered questionnaire. Knowledge, attitude, and practice were assessed by 16, 5, and 6 questions, respectively. The study included 479 dental students, of them, 291 (60.8%) were females, 359 (74.9%) were from urban areas, and 359 students (74.9%) were 22 years old and below. Only one quarter of the students had good knowledge whereas nearly half of the students (48.9%) had fair knowledge concerning ergonomics. Out of the participants, 84.8% had positive attitudes and 95.4% had poor practice of ergonomics. Only 48.9% of the studied students had fair knowledge regarding ergonomics; also 5% only of students practice it. But about 84.8% of students have a positive attitude towards studying ergonomics. Dental students need to ensure involving ergonomics in the routine dental practice. This may be achieved via addition of ergonomics in their curriculum.
Background: Egypt lies among the world's highest prevalence rates of HCV and intermediate levels of HBV infection. The objectives of the study were detection of the knowledge, attitude and practice of Medical Students of Tanta University towards hepatitis B and C. Methods: This was a cross-sectional study, conducted in The Faculty of Medicine, Tanta University, Egypt; from 15th October 2013 to 15th of January 2014. Results: The study included 185 Students; their ages ranged between 17 to 28 years with a mean 20±1.731years. Sixty percent of students were males and 65% were urban residents. 50.8% of the participants were in the basic level of the academic study. More than half (57.85%) of the participants had sufficient knowledge, 77.3% of them had a positive attitude towards hepatitis C and B and more than two-thirds (68.1%) showed good practice. A significant association occurred between a positive attitude and good practice. Sufficient knowledge was significantly recorded among older students, females, urban residents and the clinical stage students. The most frequent sources of student information were family or friends, internet followed by TV or radio, healthcare workers, and newspapers. Conclusions: The students had reasonable knowledge, positive attitude and good practices towards B and C viral hepatitis. Areas of insufficient knowledge needed to be reinforced included some modes of transmission, complications, and treatment for B and C viral hepatitis.
Expatriate workers must be medically examined in their country of origin at accredited centres prior to their arrival in any Gulf Cooperation Council (GCC) country and are reexamined when they enter the country. This review investigated the epidemiological profile of registered expatriate workers in Saudi Arabia who were found medically unfit to work. A descriptive analysis was performed on 4 272 480 records of a Ministry of Health database from 1997 to 2010. The greatest proportion of workers was from Indonesia (34.3%). The total proportion of unfit expatriate workers was low (0.71%). The highest rate of unfitness was among workers from Ethiopia (4.06%), followed by Somalia (2.41%). Hepatitis B infection was the most common cause (57.5%), followed by noncommunicable diseases (21.2%) and hepatitis C infection (17.4%). This review suggests that the total number of workers registered in the Saudi Ministry of Health was underestimated, and the rate of unfit workers was lower than for other GCC countries, suggesting that standards and quality assurance in Saudi laboratories require revision. . L'infection par le virus de l'hépatite B était la cause la plus fréquente (57,5 %), suivie par les maladies non transmissibles (21,2 %) et l'infection par le virus de l'hépatite C (17,4 %). Cette analyse semble indiquer que le nombre total de travailleurs enregistrés au ministère de la Santé saoudien était sous-estimé et que le taux de travailleurs inaptes est inférieur à celui des autres pays du Conseil de coopération du Golfe, ce qui donne à penser qu'une révision des normes et de l'assurance qualité des laboratoires saoudiens est nécessaire.املتوسط لرشق الصحية املجلة عرش التاسع املجلد السابع العدد 665
