2 Professional Information 1- Overall Aims of Course Medical Parasitology course Provides Student with Aim 1 Knowledge of parasitic diseases; causative parasites (helminthes, protozoa and arthropods), vectors of disease transmission and their pathophysiology. Aim 2 Ability of diagnosis and management of parasitic diseases in an independent manner. Aim 3 Skill of using the microscope efficiently to identify different helminthic, protozoal and arthropods stages especially the diagnostic and infective stages. Aim 4 Basic knowledge of epidemiological and environmental factors and local endemicity of parasites especially in Egypt. Aim 5 Aim 6 Ability to design a simple control and prevention strategy and offer advice for protection against communicable parasitic diseases. Skills of search through the web and team work to conduct and present a research assignment in the area of Medical Parasitology. 2 of

3 2- Intended Learning Outcomes of Course (ILOs) A. Recall of Knowledge and Understanding: By the end of the course, students will be able to: Course ILO Program ILO a1 Define terms related to medical parasitology. A6 a2 a3 a4 a5 a6 a7 a8 a9 a11 a12 a13 a14 Classify parasites of medical importance in its broad scientific taxonomic positions and their habitat in the human body. List the Definitive host, intermediate host and reservoir host if found in case of parasitic infections and zoonosis. Classify arthropods that are mechanical and biological vectors of important human pathogens. Mention arthropods infestations to man as a cause of allergy or as vectors for disease transmission. Relate the life cycle of different parasites of medical importance with pathogenesis (in terms of host- parasite relationship) of different parasitic infections. Correlate the life cycle of different parasites of medical importance in terms of host- parasite relationship to clinical picture. Describe the clinical picture of arthropods infestations to man as a cause of allergy or disease State the mode(s) of infection and transmission of different parasitic and vector borne diseases Describe the infective stage(s) of different parasitic infections and infestations. Enumerate parasites eliciting manifestations in terms of organ(s)/system(s) affection during their migration in the human body. Differentiate between parasites eliciting manifestations in terms of organ(s)/system(s) affection during their migration in the human body. Recognize basic principles of direct methods of laboratory diagnosis with special emphasis on stool, urine and blood examination A6 A6 A6 A6 A6 A8 3 of

4 a15 a16 a17 a18 a19 a20 a21 Describe the diagnostic stage(s) of parasites recovered by direct methods of laboratory diagnosis. Recognize the basic principles of immunological and molecular methods related to the diagnosis of parasitic infections. List anti- parasitic and -arthropods therapy to treat the corresponding infections and infestations important to man. Criticize pitfalls in diagnosis and treatment of parasitic diseases and suggest the proper line of management. Describe methods of prevention and control on an individual and community levels based on the life cycle of the causative parasite. Describe methods of prevention and control of arthropods infestations and vector transmitted diseases based on the ecology of the vector. Compare between different parasites as regards; morphology, geographical distribution, habitat, hosts, pathogensis, clinical picture, management and control. A8 A8 A8 A8 A10 A10 A6 A8 A10 B. Intellectual Skills By the end of the course, students will be able to: b1 b2 b3 b4 b5 Course ILO Correlate the structural and functional alteration due to different parasites with the clinical picture of diseases caused by them in terms of the host parasite relationship. Select appropriate diagnostic methods (direct and indirect) of different parasites according to life cycle. Analyze and Integrate results of history, physical examination and investigations of a case scenario to reach differential diagnosis and diagnosis of the underlying parasitic cause (s). Interpret the geographical distribution for areas where parasites are found (especially endemic areas) as a useful information in the patient history. Construct a simple control and prevention strategy for different parasitic infections in relation to the weak links in the life cycle of the causative parasite. Program ILO B2 B3 B4 B4 B8 4 of

5 C. Professional and Practical Skills By the end of the course, students will be able to: c1 c2 c3 Course ILO Identify different stages of parasites using simple or compound microscope or diagrams and comment on diagnostic, infective stages or vectors of disease transmission. Identify gross samples of some parasites (isolated or within human tissue). Examine to identify pathogenic snails (intermediate hosts of some parasites) that can be of epidemiological importance in Egypt. Program ILO c4 Practice basics of safety procedures during laboratory classes. C6 D. General and Transferable Skills By the end of the course, students will be able to: d1 d2 d3 Course ILO Respect superiors and colleagues during practical classes and small group discussions. Gather, organize and appraise information including the use of information technology where applicable. Present the medical information in written, oral and electronic forms. C1 C1 C1 Program ILO d4 Communicate ideas and arguments effectively. D7 d5 Be prepared for the lifelong learning needs of the medical profession. d6 Work constructively and cooperatively within a team. D9 d7 Practice self and peer evaluation. D10 d8 Effectively manage time. D11 D3 D4 D6 D8 5 of
