Clinical Pathology Handbook The Course
THE COURSE
Welcome to the Clinical Pathology Course. This course will allow you to build on your knowledge of the scientific
principles of disease (covered in the Part Ib Tripos Cambridge Pathology (Biology of Disease) Course or the
equivalent from other Medical Schools), and learn about specific diseases as they affect the major body systems.
Pathology in this course is taught in a variety of ways (covered in detail below). These include:
formal
lectures including
podcasts or other electronic reproductions of lectures
tutorial classes (small group teaching)
computer based learning (CBL) programs and other computer-based systems – see the Virtual Learning
Environment [VLE] (MedPortal, previously cal ed ERWEB on the Clinical School's computer system)
autopsy room teaching (by individual arrangement made in advance)
interactive large group teaching (often used for revision sessions)
The three major components, lectures/podcasts, tutorials and CBL/personal study, form part of an integrated
teaching ‘package' and each plays an equal y important role in the teaching programme. Different aspects of the
subject are covered during these various activities. Therefore, it should be appreciated that lectures/podcasts do not
completely cover the core material of the course, such that some topics are covered only or mostly in tutorials or
CBL, but not in lectures! It is important that you attend each session if maximum benefit is to be derived from the
course. It should also be appreciated that the material covered in these sessions is not comprehensive and must be
supplemented with personal reading of textbooks and other recommended sources.
AIMS
The Course aims to (1) present the pathological basis of diseases that are commonly seen in clinical
practice, and to demonstrate how clinical manifestations may be explained by the underlying pathological
processes; and (2) cover investigation of disease processes, including interpretation of test results, for
diagnosis and patient management.
On successful completion of the Course the student will be able to:
Describe the
aetiology and pathogenesis of clinically important disease processes.
Describe and interpret the basic
macroscopic appearances characterising diseased organs & tissues and
understand the
pathological processes that lead to these changes and how they relate to clinical signs &
symptoms.
Explain the
mechanisms by which clinical manifestations of diseases arise.
State the principal
complications and sequelae of disease processes.
Appreciate how the application of
pathological principles to the study of diseased tissue and fluids in the
pathology laboratory by appropriate
investigation and interpretation of data relates to diagnosis and patient
management.
Select appropriate pathological investigations for diagnosis, treatment, assessment of prognosis and
monitoring of common diseases (using tissue, blood and other fluids & samples).
Understand and be able to interpret the results of pathological investigations in different patients, in health
and disease, both in diagnosis and in following treatment.
Communicate an understanding of the role of
autopsy in clinical audit, education and research.
Understand the
limitations of diagnostic investigations.
Clinical Pathology Handbook
Appreciate the
transmission of microorganisms between the environment and living hosts, and how this
transmission may be reduced or prevented and how host defence mechanisms may be altered.
Understand the principles of how
common bacteria, viruses, fungi, protozoa and parasites cause disease,
and how these infections most commonly present.
* Know the
common infectious causes of dysfunction of each of the body's organ systems.
*
Understand the principles of how best to use
microbiological tests to make a diagnosis of infectious disease in
patients in and out of hospital.
Be able to use common
antimicrobial agents and other antimicrobial strategies effectively and efficiently.
Understand the principles of how best to use
chemical pathology tests to make a diagnosis of various
diseases in patients in and out of hospital.
Understand the principles of how best to use
immunological tests to make a diagnosis of immunological
diseases in patients in and out of hospital.
Understand the
pathophysiology and appreciate the
clinical presentation of haematological disorders.
Appreciate the
haematological aspects of systemic disease.
Develop a working knowledge of the use of
haematological investigations and their clinical
interpretation.
Be able to appropriately
manage patients with haematological disorders, in particular
anaemia and the use of
anticoagulant therapy.
Understand the
transfusion process and ensure the safe and effective use of
blood and blood products.
Integrate
all aspects of laboratory investigation for individual patients.
Lay the basis for
life-long learning of integrated clinico-pathological features of disease.
Develop an
evidence-based approach to the study of clinical pathology.
More
general aims of the course are:
to give you guidance in personal study
to give you, through your tutors, advice about your personal progress, and offer you assistance and encouragement if your progress is not satisfactory
to give you practice in communicating verbally
to provide you with channels for comment and criticism of all aspects of the course
The Course does
NOT aim:
to give complete coverage of all of systematic pathology (detailed learning objectives and/or tabulated core curricula are set out below, and these spell out what you need to know and the appropriate level of detail of that knowledge)
to get you to memorise factual information which you do not understand, or which you could easily look up in a book if you ever needed to know it
to make you into a pathologist
to make you into a nervous wreck
HELP
Your tutors (and the course organisers) will offer a sympathetic hearing to any student who is having academic or
other difficulties.
Clinical Pathology Handbook
Clinical Pathology Handbook
LECTURES
AIM: Lectures cover many, but not all, of the
major pathological topics in the
core curriculum.
Lectures will be delivered by members of the Departments of Histopathology, Medical Microbiology, Chemical
Pathology, Haematology, Clinical Immunology and Medical Genetics, who usually have a special interest and
expertise in the subjects covered. Some shared lectures will be
given jointly by 2 or more members of these
departments. Lectures are not intended to give comprehensive coverage of each system, but will be used to direct
students towards the core knowledge. Some lectures will be available in the form of podcasts or other electronic
versions. You will need to supplement lectures by reading the relevant sections of recommended textbooks of
Pathology. Handouts are generally given when standard textbooks are considered inadequate and should not be
regarded as substitutes for textbooks. Many of the lecture handouts and slides are available on the VLE.
PODCASTS
AIM: Pathology podcasts, mostly in the form of slides with voiceover explanation, are being used to cover some of
the
major pathological topics in the
core curriculum. They provide online resources for you to access,
during various stages of your course, that act as a support providing aspects of the pathological basis of
disease relevant to the placements and themes of the clinical medical course.
The Pathology podcasts have been developed by various Pathology lecturers covering a wide range of topics,
including Histopathology, Microbiology, Biochemistry, Immunology and Haematology. Podcasts are available for
components of both the Stage 1 and Stage 2 course. They are particularly important for those components of Stage 2
that were previously covered in lectures but are now covered by podcasts, allowing students to access relevant
pathological information at a time that is appropriate for their stage of progress through Stage 2 (variable for different
groups of students). The podcasts will act as online resources for students on Stage 2 block placements. The
podcasts are to be viewed during the placements and will provide core pathological information regarding some of
the conditions you will encounter during these attachments. After viewing the podcasts there will be an opportunity to
ask questions. Tutorials will be given during the Stage 2 Review & Integration weeks to support the pathological
topics in the podcasts and these tutorials will include a "Question & Answer" session at the end to cover relevant
questions and discussions arising from podcast viewing. Pathology podcasts will be available throughout Stage 1
and Stage 2 and they can be used as resources for learning or revision by any student at any point.
TUTORIALS
AIM: Structured tutorials cover selected major topics from the core curriculum in a way designed to stimulate a
problem-solving approach sometimes using
data interpretation questions and this approach is intended to
foster integration of pathological and clinical features of diseases.
You will be allocated to tutorial groups for various parts of the course. Tutorials will take place at various times set out
in the timetable and are held in either Seminar Rooms or Lecture Theatres in the Clinical School Building (or
occasionally in other locations according to availability). These structured tutorials are designed to provide you with
an opportunity for integration of pathological and clinical knowledge.
Tutorials include:
clinico-pathological cases
case problem-solving exercises (CPSE)
data interpretation questions (DIQ)
structured discussions of key pathological topics with your tutor and fellow students
Both
clinico-pathological cases and
case problem-solving exercises (CPSEs) will be used to illustrate important
pathological processes and their clinical manifestations, including investigation and interpretation of data. You must
be prepared to actively participate in discussing and providing answers for these cases and exercises in the tutorials.
Each tutorial group is presented with the same cases and problems which form the basis of the group discussions
during the tutorial. A list of titles for these sessions is given below. Whenever possible they will take place after the
Clinical Pathology Handbook
relevant lectures. You will gain maximum benefit from these sessions by conscientious preparation beforehand, by
reading the relevant lecture notes, handouts, and textbook chapters.
Active participation is essential for the
success of these sessions!
COMPUTER BASED LEARNING (CBL)
AIM: Computer-based learning provides an opportunity for
interactive learning,
problem solving and
self-
assessment.
A number of sessions (timetabled below) are devoted to the use of
CBL resources, which include Computer Aided
Learning (CAL) programs and Internet sites (URLs provided). These teaching packages are available for use in the
Clinical School Computer Teaching Laboratory at other times during the working day, through the
Virtual Learning
Environment (VLE) / Medportal - a Web-based computer environment that is accessed using a browser, such as
Internet Explorer. This environment is structured to guide students to appropriate resources available on computer.
CBL resources have a number of purposes:
Some CBLs provide interactive tutorials on important topics not covered in lectures (e.g. on certain aspects of
cervical neoplasia)
Some CAL programs provide a straightforward introduction to a subject area (e.g. 'Edinburgh PathCALs') Other CBL elements are designed to supplement the other parts of the Course, and give you an opportunity for
interactive problem-solving
Some CBLs include self-assessment questions (e.g. practice MCQs, some Internet sites & CAL programs)
SELF ASSESSMENT QUESTIONS: Lecturers, tutors and CBL provide MCQs for examinations, covering various aspects of the course. A sample of
these questions is available on the VLE/MedPortal for self assessment by students and is similar in style and content
to those used in the prize examination and the Final MB examination.
AUTOPSY ROOM TEACHING SESSIONS
AIMS: Autopsy room sessions provide you with an excellent opportunity to
correlate gross pathological structural
changes at the organ and tissue level, with clinical observations and the natural history of disease.
These take place in the Mortuary / Post Mortem Room / Autopsy Suite on Level 1. You can arrange to attend these
teaching sessions on any morning on any day of the week (Monday to Friday) when you have available time that
morning and there is a suitable autopsy case being dissected that morning (phone the mortuary / autopsy suite on
3106 or 4549 to arrange this). Please note that only 1 or 2 students at a time can be accommodated each morning.
During these sessions, the findings of
diseased organs and tissues from one or more autopsy cases will be
demonstrated and the relevant clinico-pathological correlations considered and discussed. You are strongly
encouraged to attend these sessions when possible.
INTERACTIVE LARGE GROUP TEACHING
Interactive large-group teaching sessions are used in Microbiology, Chemical Pathology and other disciplines, in
which the session leader selects individual students to
interpret data to make diagnostic and therapeutic decisions,
usually in a case-based teaching format. These may include use of ‘branching' decision-based
approaches.
CHANGES TO TIMETABLES OR TEACHING ARRANGEMENTS
Students should check for any last minute changes on VLE/MedPortal which lists the timetables or their emails.
Clinical Pathology Handbook
RECOMMENDED READING
A full list of books to accompany the different divisions included in Pathology can be found in the Clinical School
Library or in the Course Reading List under General Curriculum Information on the VLE/MedPortal. These lists are
updated twice a year to make sure that current editions are included in the list.
STAFF - STUDENT CONSULTATIONS
Channels of communication wil be established between students' representatives and the Histopathology
Department. Students will be asked to complete Feedback Questionnaires electronically, in which all major
components of the Course will be assessed. This feedback is essential to improve all aspects of the course.
EXAMINATIONS
[I] PRIZE EXAMINATION:
A voluntary competitive examination for the Henry Roy Dean Prize will be held prior to the Final MB exam consisting of
a multiple choice questionnaire (MCQ), similar in question format to the MCQ paper of the Part I Pathology Final MB
Examination (see below) lasting one hour (please see VLE/MedPortal for details).
[II] FINAL MB EXAMINATIONS:
PART I PATHOLOGY FINAL MB
The Pathology Final MB examination will be held in May/June (resit in the following October) at the end of Stage 2.
This will give adequate time not only to allow appropriate further study, but also to appreciate the fundamental role of
Pathology in the practice of clinical medicine and integrate pathological knowledge with the clinical specialities.
Clinical Pathology includes several disciplines (Biochemistry, Haematology, Microbiology, Immunology, Genetics and
Histopathology) which may at first seem unrelated. These disciplines are covered in different lectures and in
separate textbooks, and whilst this compartmentalisation provides a logical way to study, sound medical practice
requires their integration within appropriate clinical contexts and the Pathology Final MB examination will specifically
test for integration.
This examination has two main components:
(a) Multiple choice questions; (b) Practical/Data interpretation questions.
There is also a viva voce exam for selected candidates (for the possibility of achieving a distinction award).
This examination will test core areas covered in the course including biochemical, haematological, immunological,
microbiological, genetic and histopathological topics. The relative ratios of questions covering these areas will broadly
reflect the time spent studying them in lectures and tutorials during the course.
Candidates must pass BOTH the MCQ component and the Practical component separately. If a candidate fails one
component and thus fails the examination overall, then that candidate will have to resit the whole examination (and
resit both components).
(a) MULTIPLE CHOICE QUESTIONNAIRE
AIM: To test understanding and knowledge of a very broad range of topics.
There are 150 best-from-five multiple choice questions (1:5 MCQs – 150 questions). This paper contributes 50% of
the total marks and lasts for 3 hours (and is positively marked – no negative marking).
(b) PRACTICAL EXAM / DATA INTERPRETATION QUESTIONS
AIM: To test integration of understanding and knowledge of the basic clinical symptoms and signs, with pathological processes and organ changes, and with microbiological, haematological, immunological and biochemical data, by examining data interpretation and problem-solving skills in integrated clinico-pathological contexts.
Clinical Pathology Handbook
The types of problem solving and data interpretation questions which will be used, are similar to those used during
the course tutorials and in revision tutorials. These relate to integrated clinico-pathological cases, which include case
histories, data from laboratory investigations (biochemical, haematological, microbiological, immunological or
histopathological) and macroscopical images of diseased organs or tissues. These are drawn from material used in
the lectures and tutorials. The Final Practical Examination includes
10 Data Interpretation Questions. This
component contributes 50% of the total marks and lasts for 3 hours.
Although cal ed the "Practical" examination, this is a written exam in which you wil not be asked to perform any
laboratory procedures, or even to look down a microscope. This exam tests ability to apply your knowledge of
pathology in different clinical situations. Junior doctors are no longer called upon to examine urine or look at CSF
under the microscope at the bedside or side room, but they must be able to interpret quickly and act upon the results
of laboratory tests.
Each of the ten data interpretation questions is in a folder containing a brief, relevant case history, together with the
results of a few appropriate laboratory tests (e.g. U & E's, full blood count, LFT's, blood gases, microbiological or
serological data etc) and usually one or two good quality colour photographs of a named macroscopic surgical or
post-mortem specimen. For each case there will be four or five questions which can be answered briefly, but which
require
interpretation of the data.
All normal / reference range values are given. It is unnecessary to memorise
these, but essential to be well acquainted with the common tests in order to appreciate the degree of abnormality
when a result is abnormally high or low. No credit is given for writing that the sodium is low, potassium high, etc. –
the examiners can also read! Candidates are asked to suggest reasons for the abnormalities in the light of the
clinical history and photographs.
The best way to prepare is to take an interest in the patients clerked on various firms and to read and interpret their
laboratory reports. Students who have done this regularly romp through the ‘practical' exam and actually enjoy it.
Students who have failed to grasp that pathology is not only lists of causes in textbooks, will find it much harder. The
post-mortem demonstrations provide opportunities to see macroscopic specimens and all photographs are taken
from autopsies or surgical specimens resected at Addenbrooke's Hospital or other hospitals in the region.
(c) VIVA VOCE EXAM:
AIM: This aims to make a decision regarding the award of Distinctions to appropriate students who have performed
particularly well in the examination.
Students who have achieved a high standard in the MCQ and practical papers will be invited to attend for oral
examination, in which they may have the opportunity to gain a Distinction Award. Students will be requested to
attend for oral examination at the discretion of the examiners. All students attending for oral examination will usually
have
two 10-15 minute viva voce examination sessions covering all pathology disciplines.
In each viva voce examination session, the candidate will usually meet two or three examiners, one of whom will
usually be an external examiner and they will usually be questioned by at least two examiners during each session.
The viva is therefore of significance to the outstanding candidate who may be deemed worthy of distinction.
HOW TO APPROACH THIS COURSE
In the undergraduate (Part Ib Tripos or Biology of Disease or equivalent) Pathology course, you learned the basic
scientific principles of disease processes; in Clinical Pathology you will study specific diseases as they affect the
major systems of the body. Systemic Clinical Pathology is a vast subject, and in this course we aim to give emphasis
to disorders that are common and clinically important. We certainly do not intend to give comprehensive coverage of
the pathology of each system.
A good tip to start with is to revise the earlier work in General Principles of Pathology as soon as possible and at all
times try to apply it to the various systems as you work through them, as described above. Thus, when learning the
causes of gastritis, you might start with the causes of inflammation and consider which of these are important in the
case of the stomach.
The list of Systems Objectives and/or tabulated core curricula set out below should help you in your study of each
system. This information spells out for each system and discipline what you should have achieved on successful
completion of the course. You will find that many of the Systems Objectives are specifically covered in various parts
Clinical Pathology Handbook
of the teaching course, but be warned that any part of this is considered "core" knowledge and therefore examinable.
If some Systems Objectives have not been specifically covered, it is up to you to do the necessary reading. Do not
underestimate the amount of background reading that you will need to do. Use the list of Systems Objectives and
tabulated core curricula as a guide for your revision for the Final MB Examination in Pathology, as these core topics
(described in the categories "in-depth knowledge" and "familiarity" in the tabulated curricula) are appropriate for
testing in the Examination.
LEARNING OBJECTIVES
Certain broad principles apply to the objectives relating to any given disease. You should be able to:
-
define the common terms used to describe or name disease processes.
describe the epidemiology and have a rough idea about how common a disease is. You do not need to learn precise figures of disease incidence.
describe the main aetiological factors and pathogenetic mechanisms, if known. You should also be able to state if these are not known to medical science, but you should have some idea of the main theories in current use.
describe the main macroscopic morphological features of diseased organs and tissues, but the microscopic features are expected only in a few appropriate diseases. By the end of the Pathology course in 2nd Clinical Year you should already be able to work out the main gross changes you would expect in many diseases from first principles and should not find yourself committing a lot to memory by rote. In certain tissues, such as liver and kidney, there are other more specific changes in disease, but again you should be able to work these out from certain principles which apply to these tissues.
understand how pathological mechanisms affect a patient and become translated into clinical signs and symptoms.
determine appropriate laboratory investigations to make the correct diagnosis and to monitor disease progress.
describe the clinical course of the disease and common complications.
- list the disorders which are recognised precursors of certain well-defined clinical syndromes or entities e.g., hypertension, nephrotic syndrome, haematemesis, coma. You may refer to the accompanying chart for lists of topics to be covered in different degrees of detail for each system.

CURRICULUM IN MEDICAL MICROBIOLOGY
This tabulated curriculum provides a guide to the standard required: a student who shows several significant gaps in knowledge in the areas "in depth knowledge" and "familiarity" categories (these include the core topics) would be unlikely to pass. A student who lacks gaps in these areas and demonstrates a good level of understanding of this knowledge, and shows some knowledge of several areas in "passing knowledge" and "heard of" categories, would be in the running for a distinction. The course aims to build a clinical perspective on to the scientific basis of micro-organisms and infection, and on to the practical experience you gained of manipulating micro-organisms, in the pre-clinical course. The tabulated Core Curriculum in Microbiology includes those areas of the syllabus that were mainly covered in the pre-clinical course. We have little time to review these areas during the Block Course, but we remind you of such information when it is vital to understanding of the new material. Textbooks in microbiology rapidly go out of date, and many on the market are:
too detailed and advanced, and/or
too focussed on laboratory aspects of micro-organisms, and/or
too focussed on clinical aspects of patient management.
Hence, we provide handouts for most lectures and symposia in the Microbiology course. Our handouts in
microbiology are aimed to present the necessary information in a way that will be of practical use to you when you
are house staff dealing with patients. Such core information is sometimes
boxed or
highlighted to make it clearer.
Extra information appears as smaller font text: this may be about less common infections, drugs or syndromes, or
may cover the scientific or patho-physiological background to infectious diseases. Many of our handouts also give
references to recent reviews or primary publications in the medical literature, and occasionally web-based resources -
these are recommended to students who wish to read further, at distinction standard.
The well-rounded student will be able at the end of the course to view their microbiological knowledge from several perspectives: for example, the questions:
which micro-organisms commonly cause wound infection?
which infections are commonly caused by
Staphylococcus aureus?
which antibiotics are often used to treat
Staphylococcus aureus infections?
name some infections commonly treated with flucloxacillin.
which antibiotics are often used to treat IV catheter infections?
all draw on the same closely-related fund of knowledge.
LECTURES
In microbiology, we cover most (but not all) the topics in the "in depth knowledge" and "familiarity" sections of the core
curriculum during the lectures and tutorials.
PODCASTS There are also a number of Microbiology podcasts, which have been developed by the Microbiology lecturers to
cover some of the major microbiological topics in the core curriculum.
TUTORIALS
In microbiology these are usually case-based, and we encourage a high degree of student participation. They are
usually based on written details of cases, which are therefore similar in format to the Data Handling questions in the
final examination. The aims are for students to involve themselves in the management of real cases, to see the
impact of their diagnostic and therapeutic decisions, and to appreciate the interaction of the microbiology laboratory
with clinical services in and out of hospital.
Please read the relevant lecture notes and look at the appropriate CBL resources before the sessions - it is a waste
of resources if these sessions have to become mini-lectures because of lack of preparation on the part of the
participants! Because of time limitations elsewhere in the course, some new primary knowledge is introduced during
Clinical Pathology Handbook
Medical Microbiology
these sessions. We do not have enough staff to allocate a single tutor to groups of students throughout their course, and students may have the same broad subjects covered by a bacteriologist or a virologist.
