Mechanisms of diseases
A.Y. 2020/2021
Learning objectives
The course focuses on the causes of cell, tissue, and organ injury (general pathology), on the major groups of microbial pathogens that cause human diseases (microbiology), on the principal mechanisms of responses to injury and defense (inflammation and immunity), and on the general processes of the most relevant causes of human diseases (genetics, vascular pathology, oncology).
Integrating contributions from different disciplines, the course offers a comprehensive description of the main different mechanisms of disease organized in 11 modules:
A. Cellular pathology
B. Medical genetics
C. Basic concepts on pathogens
D. Virology
E. Microbiology
F. Inflammation and innate immunity
G. Adaptive immunity
H. Immunopathology
I. Oncology
J. Vascular pathology
K. Biotechnology approaches in translational medicine

Course syllabus and organization
Single session
Responsible
For the lessons of the 1st semester the teaching, given the current health situation, will be carried out entirely at a distance.
Prerequisites for admission
To take the Mechanisms of Diseases exam, students must have already taken all the exams of the first year (Fundamentals of Basic Sciences, Cells Molecules and Genes 1 and 2, Human Body).
Assessment methods and Criteria
The exam will be based on two written parts and three oral parts:
· The WRITTEN TEST 1 will be based on 30 multiple choice questions of general pathology, immunology and microbiology;
· The WRITTEN TEST 2 is composed of 32 multiple choice questions of genetics (16 questions), biochemistry (8 questions) and methodology (8 questions). Each exact answer will value one point and the test will result in a mark from 18 to 30L
· The ORAL EXAMINATION 1 will evaluate general pathology and will result in a mark from 18 to 30.
· The ORAL EXAMINATION 2 will evaluate immunology and will result in a mark from 18 to 30.
· The ORAL EXAMINATION 3 will evaluate microbiology and will result in a mark from 18 to 30.
The written test 1 has a threshold of 23/30 and will not contribute to the final mark.
The written test 2 and all oral examinations tests will contribute to the final mark according to the following algorithm based on the proportion of the CFUs dedicated to each subject:
Written test 2 (genetics/biochemistry/methodology; 4 CFU): mark x/30 x 0.15
Oral examination 1 (general pathology; 7 CFU): mark x/30 x 0.3
Oral examination 2 (immunology; 7 CFU): mark x/30 x 0.3
Oral examination 3 (microbiology; 6 CFU): mark x/30 x 0.25
The final score will be implemented with the score obtained in the journal club session (from 0 to 2 points).
Written tests can be taken independently from each other.
Only students who have passed the written test 1 tests are allowed to take the oral examinations.
The written exams and the oral examinations can be sustained in different dates.
The oral examination sessions 1&2 have to be taken in a single session, the oral examination session 3 can be taken independently from 1&2.
Marks obtained in the different sessions will be considered valid indefinitely.
Registration through SIFA is mandatory.
