02359 - General Pathology and Physiopathology (AK-C)

Learning outcomes

The students will learn the etiology of the disease processes, the pathogenetic mechanism of their development, the basic reactions to abnormal stimuli and the morphological changes they induce in cells and tissues, together with the systemic and functional consequences for the organism. By the elaboration of molecular, morphologic, microbiologic and immunologic knowledges, the students will understand the wherefores of the signs and symptoms manifested by patients and will be provided with a sound foundation for evidence based medicine.

Teaching methods

The course includes 64 hours of lessons on environmental, cellular and extracellular pathology, inflammatory-reparative response and general physiopathology

Assessment methods

The level of learning is verified at the end of the lectures. The verification of learning takes place through a single oral examination for the entire Integrated Course. Two questions will be asked by two different members of the examination board: one of the two will regard a practical microscopy test to assess the learning level of the General Pathology Laboratory.
The exam aims at evaluating the student knowledge level on the teaching topics in order to achieve the educational goals. The exam assesses the student's ability to frame the topic of general pathology or general pathophysiology on which he/she is asked and to expose them by making the necessary logical-deductive connections, also in relationship to specific morphological features. The coherence of the conceptual succession and the appropriateness of the scientific language are further elements of evaluation. The examination of the General Pathology and Physiopathology Course includes the observation and oral description of a microscopic preparation up to the recognition of the specific histopathological picture. The student is expected to discuss the morphological alterations in relation to the theoretical and practical knowledge acquired during the course.
Final grade grading
18-20: knowledge of the basic concepts without serious gaps. Exposition of concepts and language as a whole acceptable.
21-25: knowledge of the basic concepts without gaps. Ability to analyze and link in partial autonomy. Exposition of concepts and language fair.
26-29: preparation of good or very good level or even excellent preparation but with inaccuracies in the presentation that compromise the achievement of the full grade. Ability to analyze and link the subjects. Exposition of concepts in the right succession and command of the language.
30-30L: full preparation, consolidated and without inaccuracies on the topics covered in the course. Ability to promptly frame the topic. Ability to analyze and connect independently. Concepts in the proper sequence and full command of the specific language.
The final grade is derived from the joint evaluation of the committee members who examined the student
