Evaluation of BSc Radiologic Sciences and Medical Imaging Technology Programmes in Sudanese Universities from Students’ Perspective

This study sets the objective to involve undergraduate students in the evaluation of radiologic sciences and medical imaging technology programmes in Sudanese universities. Based on the analysis of survey results in which the participants (BSc students undertaking radiologic sciences and medical imaging technology programmes at university level) are asked to answer both closed and open-ended questions, the study seeks to reveal the participants’ perceptions and introspections about the radiologic sciences and medical imaging technology programmes in Sudan. It also attempts to explore the participants’ suggestions and recommendations as to enhance the quality of these programmes with an eye to helping syllabus designers to improve these programmes, thereby bettering healthcare services for the larger good to the community. A brief cross-sectional survey is completed by a total of 105 radiologic sciences and medical imaging technology students, i.e. 39 (37.1%) third-year students and 66 (62.9%) fourth-year students. The majority of participants is satisfied with the programmes, indicating that they are up-to-date and ran abreast with the latest developments in the field. Very few suggest that the programmes should be reviewed for revision, implying that there is room for improvement. Some participants recommend that more training hours in modern imaging modalities (e.g. MRI, CT and U/S) should be introduced. Only one participant recommends the introduction of advanced training centres.

A Culturally-Sensitive Model for CME Distance Learning Demonstratesa Way Forward： Kenya＇s Experience with ACME-IT （Advancing Continuing Medical Education Through Information Technology）

A distance learning Continuing Medical Education （CME） project based on live interactive presentations and a group participatory model demonstrated that important strides can be made in the quality of CME available to health care professionals in African rural settings. Implementers choose a communication model consistent with the fundamental orality of Kenyan and other sub-Saharan African countries. The project involved four hospitals and one training institution in rural Kenya. The testing of learners and focus group discussions with learners, facilitators and presenters indicated that the project＇s methodologies, that strove to be culturally and work place friendly, contributed to gains in knowledge, competencies including case management, the continuity of patient care, team work, staff morale and other issues of expressed importance to the hospital healthcare work force and hospital administrators. The learning system, known as Advancing Continuing Medical Education through Information Technology （ACME-IT）, was implemented by the Kenyan Ministry of Medical Services, EC Associates and the US-funded Aphia2 Western initiative implemented by PATH. The findings of this pilot suggests that the ACME-IT methodology that set up learning centers at the participating institutions is a promising viable alternative to the traditional and relatively expensive workshop training that characterizes much of CME in lower and middle income countries.

Application and Practice of Traditional Chinese Medicine Characteristic Technology Inheritance in Research and Development of Traditional Chinese Medicine Preparations in Medical Institutions

Medical institution preparations play an important role in the development of hospitals,being one of the main forms of traditional Chinese medicine clinical characteristic medication,as well as an important carrier for the inheritance and innovation of traditional Chinese medicine.In recent years,the research and development of traditional Chinese medicine preparations has become a hot spot in the research and development of preparations by medical institutions.Traditional Chinese medicine preparations prepared by traditional processes and their entrusted preparation matters have changed from the current licensing management to filing management.The registration model of traditional Chinese medicine preparations has undergone significant changes,emphasizing more on real data and evaluation results from the objective world,respecting traditional medication experience,and emphasizing the inheritance and innovative development of traditional technological experience.In the process of following teachers in the inheritance project of traditional Chinese medicine,we combined the inheritance of traditional Chinese medicine characteristic technology with the research and development practice of traditional Chinese medicine preparations in medical institutions,and focused on the analysis and discussion of technical problems such as prescription screening,dosage form selection,process route design and clinical observation of traditional Chinese medicine preparations,hoping to provide reference for scholars in the same field of traditional Chinese medicine.

Cytotoxicity Tests for Evaluating Medical Devices: An Alert for the Development of Biotechnology Health Products

The risks and damages related to the use of products, technologies and services of sanitary interest can be due to defects or manufacturing failures. Certain products already contain a certain degree of risk, which requires strict quality control in their production, distribution and use, as well as in the disposal of their waste in the environment. With continuous development in science and technology, medical devices must undergo intradermal irritation and testing for sensitization, cytotoxicity, and acute systemic toxicity. In health care, biotechnology aims to provide technology-based products or processes related to energy, food, and health, which are capable of stimulating new businesses, expanding exports, integrating the value chain and stimulating new demands for innovative products and processes, taking into account health policies. The present article was prepared by a bibliographical survey of the electronic databases PubMed, Lilacs, and Bireme. Cell culture testing can be successfully employed, as it is reproducible, rapid, sensitive, and financially accessible for performing in vitro toxicity testing. Thus, it has been possible to optimize the development phase of new products by decreasing animal use or even replacing them in certain tests. Some in vitro assays validated by the Organization for Economic Cooperation and Development in the area of health products have already replaced animal testing.
