Objectives

MICROBIOLOGY AND CLINICAL MICROBIOLOGY At the end of this course students should:
- be able to describe the structure and function of microorganisms;
- be able to describe the mechanisms of infectious disease transmission and pathogenicity;
- be able to describe in detail those classes of microorganisms of specific relevance to the common diseases.
GENERAL PATHOLOGY
Analyze the health problems of women in their biological-sexual cycle and in particularknow what is meant by disease status and the relationship between disease status and pathological changes.Know the physical, chemical, genetic and biological factors that contribute to the onset of diseases.Know the fundamental mechanisms of defense of the cell, tissues, organs and organism.Know the fundamental molecular and cellular mechanisms that play a decisive role in the pathogenesis of inflammatory diseases.Know the main types of neoplasia and the classification criteria of tumors; the molecular basis of benign and malignant tumors in humans.Know the basic stages of carcinogenesis, and understand the role of genetic and environmental risk factors.All the above knowledge must help to understand the fundamentals of the pathophysiology to be applied to the different clinical situations of pregnant gynecological pathologies.
Knowledge and ability to understand.
Learning outcomes
At the end of the course the student must be able to describe:

Contents

MICROBIOLOGY AND CLINICAL MICROBIOLOGY
The course provides learning in the basic principles of medical microbiology and infectious disease. It covers mechanisms of infectious disease transmission, principles of aseptic practice, and the role of the human body’s normal microbiota. The biology of bacterial, viral, and fungal pathogens and the diseases they cause are covered. The course provides the conceptual basis for understanding pathogenic microorganisms and the mechanisms by which they cause disease in the human body. Classes of microorganisms of specific relevance to the common diseases will be discussed in detail.

GENERAL PATHOLOGY
Health status and causes of illness.InflammationThe fever.Classification of tumors. Chemical and viral carcinogenesis. Concept of oncogene and antioncogene.Alpha- and beta- thalassemias.Pathology of haemostasis and coagulation.Antigens and antibodies. Organs and cells of the immune system. The immune response.
LABORATORY DIAGNOSTICS
To know the genetic characteristics of some types of tumors, with particular regard to those of the reproductive system.

Evaluation methods

Verification of learning:

The exam method is an oral test designed to verify the results of the expected learning, in accordance with the educational and specific objectives of the course. The oral examination is placed at the end of the course, after having achieved the attendance to the same, according to a schedule established and published on the University web page at the beginning of the academic year. The outcome of the test is evaluated as the result of learning the specific and training objectives, such as knowledge and understanding, capacity for logical integration and application. At the end of the test the teacher will form an opinion expressed in terms of Italian grades and their correspondent European Credit Transfer System grade (In Italian Universities grades are given on the basis of 30 points).
1) Rating 30 - 30 cum laude (corresponding to ECTS grade A): Excellent knowledge and understanding of the subjects, ability to reason and logical integration of the acquired knowledge. If the student, who has achieved this evaluation, demonstrates autonomy of judgment, high communication skills and autonomous learning skills, a laude can be added by the commision.
2) Rating 27 - 29 (corresponding to ECTS grade B): Good knowledge and understanding of the topics with some non-serious inaccuracies and with a good capacity for logical integration and judgment.
3) Rating: 23 - 26 (corresponding to ECTS grade C): Discrete knowledge and understanding of the topics and, despite some gaps in the ability to integrate and apply knowledge.
4) Rating 20 - 22 (corresponding to ECTS grade D): Knowledge and understanding of the arguments fully sufficient, although there are clear gaps, which are reflected in a reduced capacity for integration, logic and application.
5) Rating 18 - 19 (corresponding to ECTS grade E): Knowledge and understanding of the topics with serious and evident gaps, with limited integrative and applicative skills, but which also allow the passing of the exam.
N.B. For Integrated Courses (exams covering more than one module or course unit) a single exam will be held and a final grade given.
