F. Integrated Service Training

1.  Duration

All Anatomic Pathology residents receive integrated training throughout the Surgical Pathology and other rotations.

2.  Training Goals and Objectives

See goals and objectives for Section E - Surgical Pathology Rotation.
Additional goals and objectives may be specified for each section described below.

3.  Advanced Diagnostic Techniques

Residents receive integrated training in advanced diagnostic techniques throughout the clinical and research rotations at NIH.

4.  Dermatopathology

Skin biopsies are reviewed in twice weekly sessions with a consultant dermatopathologist (Dr. Stern), pathology residents, and members of the Dermatology Branch, CCR. Dr. Stern may sign out the case as the primary staff pathologist, or be listed as a consultant staff pathologist. Following the review of these cases, Dr. Stern presents dermatopathology slides from outside NIH in an informal teaching conference of pathology residents and dermatopathology fellows. Advanced residents with a special interest in dermatopathology may request to spend additional time with Dr. Stern in sign-out sessions at a large private pathology laboratory. In addition, Dr. Duray provides expertise in neoplastic dermatopathology.

5.  Flow Cytometry

Overview:

The Flow Cytometry Laboratory directly receives diagnostic specimens from in-house patients for evaluation (i.e., they do not go through Histology). Flow cytometric analysis provides critical diagnostic information that is used in treatment decisions. We therefore must assure that these specimens are appropriately handled so that diagnoses can be rendered on an emergency basis when needed and to avoid destruction of the specimen. The resident on-call may be notified concerning a specimen for flow cytometric analysis. This has occurred in the past and is expected in the future. You therefore need to be aware of the proper procedure for handling these specimens. If you have any questions concerning the proper procedure for handling a flow cytometry specimen, please contact Dr. Maryalice Stetler-Stevenson or Dr. Jeffrey Schrager.

Contact either Dr. Maryalice Stetler-Stevenson or Dr. Jeffrey Schrager when you first hear about a flow specimen:

Dr. Maryalice Stetler-Stevenson:

  • Pager:  104-4075- 7
  • Office/Lab:  301-402-1424 or 301-402-1716
Dr. Jeffrey Schrager:

  • Pager:  104-5345
  • Office/Lab:  301-496-4709

We have answering machines at home and at the office. If you don't reach one of us you should leave a message on all 4 of these machines, including the phone number you can be reached at. Do not simply accept specimens without attempting to contact us. We will try to stain cells on the weekend when possible. We can also store specimens in a manner using techniques that can not be done by the novice.

                               OR

If we are unavailable, contact the Flow Cytometry Technologists:

Catherine McCoy:
  301-402-17176
Greg Jasper:  301-435-2640

If you cannot contact any of the above people, keep trying until you do.

  • Keep us informed if procedure is canceled.

  • Optimal results are obtained with fresh material. Inform the clinician of this and tell them to schedule specimen collection during weekdays, if possible. However, as leukemic patients can have emergencies on Friday night and during the weekend, we will have to receive specimens during this time period.

  • Instruct clinician how to obtain and store specimen for immunophenotyping as follows (Do not simply ask if they know how to, instruct them in our method).

Bone Marrow Aspirates:  Prepare the following Transport Media:

  1. Place 15 ml RPMI with 10% fetal calf serum in a 50 ml conical tube. RPMI without fetal calf serum is acceptable. If RPMI is not available, PBS can be used.
  2. Add 50,000 units of heparin in 5 ml PBS to final volume of 2,500 units/ml.
  3. Use sterile heparin to rinse out the syringe and needle before aspiration (sterile heparin is available from the Nurses Station).
  4. Immediately post-aspiration, place 3-5 ml of bone marrow aspirate for Flow Lab in Transport or Storage Media. Cap tightly and mix by inverting 5-6 times.
  5. Have the bone marrow technologist prepare 2 unstained smears of the bone marrow for Pathology. This is critical so stress this to the clinical fellow. Failure to provide smears may make it impossible to do a TDT.
  6. Label all specimens with patient name and unit number, date, type of specimen.

Peripheral Blood:

  1. Peripheral bloods can be kept at room temperature overnight. As the temperature in the NIH Clinical Center is so variable, we recommend placing the peripheral blood in an empty styrofoam container with a lid (the type routinely used to ship specimens on ice). There is a container outside of Room 6N-109 for this purpose.

  2. If you have contacted the Flow Lab staff, you will have been told where to put the specimen and it is your responsibility to make sure that it gets to the location you are told. If you have not successfully contacted anyone, leave a message on the home and work answering machines of Catherine McCoy, Gregory Jasper, and Dr. Maryalice Stetler-Stevenson. Include the name and pager number of the clinical fellow who is on-call and covering the patient. We will contact the fellow concerning the specimen. The clinical fellow should call the Flow Lab first thing on Monday morning.

6.  Immunopathology

Immunopathology is integrated with other rotations. The resident will learn the role of immunologic techniques, including flow cytometry and immunohistochemistry, in the diagnosis of benign and malignant lymphoid lesions. The resident assumes the responsibility for ordering and interpreting immunologic assays.

7.  Immunohistochemistry

The Immunohistochemistry Laboratory, supervised by Dr. Mark Raffeld, provides diagnostic immunohistochemistry support for all pathology services in the Laboratory of Pathology (LP) using state-of-the-art automated equipment. The service maintains a stock of more than 140 antibodies for diagnostic marker studies on frozen and paraffin tissues. The service processes about 2,600 cases each year, accounting for about 25,000 immuno stains. This represents 1/3 of all surgical pathology specimens seen in the LP. The average turnaround time for an immunohistochemistry request is a little over 1 day, allowing the immunohistochemistry analysis to be viewed in the context of the entire case during sign-out. As a result of this integrated approach to immunohistochemistry and surgical pathology, residents are continually exposed to diagnostic immunohistochemical marker studies during their clinical rotations.

The residents may also participate directly in activities of the Immunohistochemistry Laboratory. This includes instruction in both classical "manual" staining procedures using both direct and indirect methods using ABC detection, as well as training in automated procedures. Antigen recovery techniques are emphasized, such as microwave treatment and protease treatment. Residents participate in research and development of new antibodies and assess their clinical utility. Residents are also instructed on how to evaluate the adequacy of staining and to troubleshoot problems that may arise.

The department (or Laboratory of Pathology?) sometimes, but not always, has a surgical pathology fellow. The surgical pathology fellow assumes the responsibilities of the senior staff, but cannot independently sign reports. All reports are reviewed and signed by a senior staff member. The fellow assists in the training of new residents by reviewing blocking procedures and conducting training sessions in normal histology and microscopic evaluation. Second-year residents also help in the orientation of junior residents. Each first-year resident is paired with a second-year resident during their orientation month, to learn the approach to diagnostic pathology, and the procedures entailed in working up a specimen and issuing a report.

Ordering and Reporting Procedures for Immunohistochemistry:

Immunohistochemical staining is an integral component of modern pathologic diagnosis. A high proportion of cases will require immunohistochemical stains for sign-out. It is the resident's responsibility to see that immunostains are ordered, and cases signed out in a timely manner.

Requests for immunohistochemical staining should be brought directly to Room 2B58. Request forms must be filled out completely; otherwise they may be returned. It is also essential that requests be entered with the SoftPath computer system.

  • Do not order stains that are not on the Immunohistochemistry Request Form without speaking to Dr. Raffeld.

  • The resident is responsible to ensure that paraffin blocks or unstained sections prepared on coated or charged slides are available for staining when submitting a request on submitted material.

  • All cases are stained within 24 hours of receiving appropriate unstained slides from the Histology Lab or directly from the submitter.

  • In cases where no unstained slides are available from Histology, the Immunohistology technologists prepare and stain the slides within 72 hours of receipt of the staining request and block.

  • Rush cases must be brought to the laboratory before 10:00 AM to have the slides returned on the same day.

  • The slides are then reviewed daily by the Immunohistochemistry unit professional staff for quality control, and distributed to the attending resident and attending staff for final interpretation.

  • The final interpretation of the immunohistochemical stains is performed by the attending staff pathologist and resident responsible for the case. The immunohistochemical results are incorporated into the surgical pathology report.

  • In the event that a case has been signed out prior to receipt of the immunohistochemistry stains, a supplemental report must be generated.

  • ALL IMMUNOSTAINS MUST BE DOCUMENTED IN YOUR REPORTS.

8.  In Situ Hybridization

The In Situ Hybridization Unit provides the resident with practical experience using diagnostic and research tools that are applicable to biomedical research in cancer and other fields. The In Situ Hybridization Unit is responsible for clinical testing for Epstein Barr viral (EBV) sequences using the EBER RNA probe. Results of EBV in situ hybridization are reviewed by the resident, and these data are integrated into the surgical pathology or molecular diagnostic report. The resident also reviews test slides to determine the preservation of RNA in the clinical sample.

Quality Improvement Activities

The Quality Improvement (QI) Program is designed to continually evaluate the quality of clinical services generated throughout the Laboratory of Pathology (LP). This is accomplished by monitoring and evaluating quality improvement indicators for the Laboratory of Pathology and assisting each individual laboratory unit in the identification of areas that can be improved upon to maximize the quality of service and of patient care provided. The autopsy pathology resident attends the QI Committee meetings as a "resident member" during their service months for the purpose of providing an education experience and an opportunity to contribute to the ongoing improvement efforts of the QI Committee. The complete program, procedures and data are available for review by the chair of the QI Committee. Residents are also encouraged and asked to volunteer as needed for committees for the purposes of strategic planning, process improvements, organizational evaluation, and policy development, etc.

Requests for Human Biological Materials

The Laboratory of Pathology (LP) Tissue Research Committee (TRC) is charged with the development and implementation of a process through which basic science observations and translational pathology studies will be prioritized and executed within the LP. The TRC also reviews requests for human biological materials from the pathology archives to ensure that these materials meet ethical guidelines.

The senior resident participates in reviewing tissue requests in concert with a staff pathologist. As part of this process they are trained in the guidelines that govern the research use of human tissues. The complete TRC procedure can be obtained through the Clinical Laboratory Manager.

Principles and Practice of Clinical Research

The residents are encouraged to take the "Introduction to the Principles and Practice of Clinical Research" offered through the NIH Clinical Center, in the second or third year of the Residency Training Program. This 32-session course covers epidemiological methods, ethical issues and regulation of human subjects research, monitoring patient-oriented research and regulatory issues, and preparing and funding a clinical research study. Sessions usually start each January and end in May. Schedule and registration information is located at http://www.cc.nih.gov/OD/corecourse/index2.html

Laboratory Information Systems

The Laboratory of Pathology? uses the SoftPath™ Laboratory Information System (LIS) to accession, process, and manage patient cases. Resident education in medical informatics occurs as they learn the LIS. The LIS is used for, but not limited to,  case management and data management, including ordering additional cuts or special stains on cases, reviewing the history of patients scheduled for operating room procedures or for the tumor board, looking up the case status or diagnosis of a patient, printing case status logs, generating case reports, tracking physician notification, printing worksheets, recording outgoing consultations, exporting data to MS Access for direct research, etc. Residents will gain user experience with all aspects of the pathology information system. A LIS user manual is located in the resident's office and in each section of the laboratory and contains instructions for all LIS procedures as well as the disaster or system failure protocol.

10. Molecular Diagnostics

11.  Neuromuscular Pathology

Duration

Neuropathology is integrated in autopsy and surgical pathology. The specialties are closely related and exchange information informally as well as formally through interdepartmental consultations, conferences, teaching programs, and research.

The training program in neuropathology is aimed at providing the resident with the expertise necessary to practice aspects of neuropathology independently and effectively. During neuropathology training, the resident concentrates on developing a solid background in the basic neurosciences and diagnostic neuropathology by review of assigned surgical and autopsy cases in-house or sent in consultation to the department from intra- and extramural sources; utilization of special techniques for light microscopy, including immunohistochemistry, enzyme histochemistry for muscle biopsies and electron microscopy; participation in research projects with members of the department staff; and attending national meetings related to neuropathology.

Neuropathology residents are assigned surgical and autopsy cases sent in consultation to the Neuropathology Unit from intra- and extramural sources. Supervised by one of the teaching staff, the resident reviews the case and presents his/her analysis and recommendations for additional studies, if needed, to the teaching staff at the teaching and sign-out conferences. Clinicopathologic correlation is emphasized during the case discussions. With the approval of the teaching staff, the resident prepares a written summary and case diagnosis which is reviewed, corrected if necessary, and submitted as a final report. The residents participate in brain cutting and microscopic diagnostic review sessions of a variety of medico-legal cases (when rotating in the Medical Examiner’s Office) and regular autopsy cases. Experience in pediatric and perinatal neuropathology is obtained during rotations at the Children’s National Medical Center, Washington, DC. Experience in cytopathology of central nervous system (CNS) fluids is obtained through cytopathology rotations.

      The resident must develop the ability to critically evaluate the quality of research studies and to be discriminating in the selection of information sources used to support medical decision making.

    2. Use of Information Technology
      The resident will learn to use a variety of information technologies to inform and improve his/her day-to-day practice of neuropathology. Examples of information technologies that must be mastered include electronic medical literature databases, Web-based information sources, and computer-based resources (CDs and other media).

  4. Interpersonal and Communication Skills
    1. Communication Skills
      The resident will learn to communicate effectively and courteously with health care providers, laboratory staff members, administrators, patients, and other individuals in the course of her/his practice. These communications will include verbal (face-to-face and telephone conversations) and written (written reports, notes, e-mail messages, etc.) formats. The resident must strive to communicate in a clear, concise, accurate, and appropriately focused manner. Regarding the production of written reports, the ultimate goal is for the resident to produce essentially letter-perfect reports that require minimal or no modification by the attending pathologist, and that convey essential diagnostic information in a clear and concise manner.

    2. Teamwork
      The resident will learn to work as an effective member of the health care team in the course of his/her daily practice. The resident must strive to perform her/his tasks in a responsible and timely fashion, facilitate the tasks of other team members, and be cooperative in his/her interactions with team members. (Note: Other team members may include technologists, transcriptionists, other residents, fellows, attending pathologists, clinicians, administrators, and others.)

  5. Professionalism
    1. Courtesy and Collegiality
      The resident must learn to treat health care providers (including clinicians, nurses, other pathologists, technologists, transcriptionists, etc.), administrators, patients, and others courteously and respectfully. The resident must learn to be collegial in all interactions with other members of the health care team.

    2. Professional Responsibility
      The resident must learn to take his/her professional responsibilities seriously and act accordingly. The resident's professional responsibilities may include clinical service (including on-call responsibilities), teaching, administrative tasks, research, institutional tasks, and work with professional organizations. The resident should strive to approach each of these responsibilities with enthusiasm and complete all tasks and assignments effectively and in a timely fashion.

  6. Systems-Based Practice
    1. The Health Care System and the Role of Neuropathology
      The resident must acquire knowledge of practice and health care delivery systems and an awareness of the role of neuropathology in the context of the greater health care system. The resident will develop a working knowledge of different inpatient and outpatient delivery systems and the general regulatory and financial aspects of health care delivery. The resident must learn the importance of providing effective and timely consultation to clinicians, advising health care providers in the provision of cost-effective care, while cognizant and in accord with patient privacy and confidentiality. The resident should learn to provide coding, statistical and other relevant data, as needed in support of quality care and the Institution.

    2. General Laboratory Administration
      The resident will develop an understanding of the general administrative aspects of pathology practice. The resident will learn to understand and apply the principles of quality control, quality assurance, and continuous quality improvement. The resident will develop a working knowledge of laboratory staffing, laboratory instrumentation, workflow, turnaround time management, safety, customer service, regulatory accreditation, budget, and billing practices.
Neuropathology Autopsy

Prior to starting the autopsy, determine, from the clinical history, the presence or absence of neurological manifestations. This will help you to plan re: taking tissue for special studies, giving tissue for research, and in examining the brain and spinal cord for clinically relevant findings. (See Safety Manual for cases of brain removal in cases with infections or other hazards.)

Brain removal, while generally done by the morgue attendant, should be learned by the resident as well.

Prior to fixation, weigh the brain:

  • Look for evidence of meningeal infection and culture as needed.
  • Look for abscess exposed to the brain's surface and culture as needed.
  • Look at the base of the skull for evidence of meningiomas and sample and photograph.
  • Consider whether the pituitary gland would be of diagnostic interest in your case.
  • The brain should be floated in 20% formalin, suspended by a string going under the basilar artery.
  • The brain must fix for 2 weeks in 20% formalin before it is cut.
  • It must be rinsed for 24 hours prior to brain cutting conference.

There are standard description forms for both demented and non-demented patients (Appendix B2).

Neuromuscular Pathology Surgicals

Neuropathology surgical specimens (in-house, submitted) are signed out with Dr. Quezado (Beeper:  104-6222).
Frozen sections are done in consultation with the neuropathologist.

Nerve:  The nerve should be received in saline moistened gauze,  not in fixative! Fresh peripheral nerve that is for a diagnosis of a neurologic illness (the excludes vagotomies) must be divided as follows:

  • One cm of nerve should be laid out on a piece of a 3x5 card and immersed in glutaraldehyde to allow for both cross-section and longitudinal section embedding for electron microscopy.
  • An additional 1 cm should be fixed in glutaraldehyde for nerve teasing, if demyelination is suspected.
  • Two small pieces, approximately 0.3.cm each,should be fixed in formalin for cross-section and longitudinal section evaluation at the light microscope.
  • A section of the nerve must be frozen if there is evaluation at the light microscope.
  • A section of the nerve must be frozen if there is any suspicion of paraneoplastic disease, to allow for immunofluorscence for immunoglobulin deposition. See Appendix B2 (pages from Dyck Peripheral Neuropathy on nerve biopsies).

Muscle and Muscle and Fascia:

  • The muscle should be received in a muscle clamp, fresh from surgery, without any fixative. It may be wrapped in saline-moistened gauze until it is ready for processing.
  • The muscle must then be divided for different methods of processing. The muscle inside the clamp (between the teeth) must be used for snap-frozen sections for histochemistry (dipped in isopentane suspended in liquid nitrogen, on a cork base with a touch of OCT to hold it down--DO NOT COVER WITH OCT AS THIS WILL DELAY FREEZING). The muscle outside of the clamp's teeth is to be used both for electron microscopy and paraffin embedding. This tissue can be divided with a few small pieces of unadulterated muscle going into glutaraldehyde (usually cut into pieces measuring 1x1x2mm each). A larger piece should be submitted for routine H&E staining and trichrome and should be sufficient to allow for embedding longitudinally and in cross-section.
  • The stains ordered routinely should include:
    • H&E on both paraffin and frozen;
    • On snap-frozen tissue:  trichrome, ATPase at pH4.3. and 10.4, NADH, PAS, fat, cytochrome C (and dystrophin for all patients less than 20 years of age);
    • Cytochrome C and dystrophin are immunohistochemical stains;
    • The remainder are histochemical (NAD& ATPase are enzyme histochemistry).
    • See Appendix B2 from Muscle Biopsy, a laboratory investigation, by Mike Loughlin.

Pituitaries:  Need only one (1) H&E and one (1) reticulin on each specimen submitted. If the tumor is grossly obvious, the immunohistochemical stains for the purported syndrome may be ordered at the time that the specimen is received, as follows:

    • Cushings Syndrome - ACTH
    • Prolactinoma - prolactin
    • Acromegaly - growth hormone

12. Pediatric Pathology

  1. Patient Care
    1. Technical Skills

13. Ultrastructural Pathology

Hands-on-the-Scope/Introductory Teaching

All first-year residents are required to spend a month in the Ultrastructural Pathology Section, learning how to use an electron microscope to scope and photograph pertinent diagnostic features. A set of 15 cases has been prepared for this reason. The residents are given representative H&E slides, short clinical summaries, and thick- and thin-sections and are asked to photograph fields that will lead them to a differential diagnosis. Their findings and thoughts are discussed with Dr. Tsokos, who supervises them closely and suggests pertinent bibliography for review.

Electron Microscopy on Current or Potential NIH Clinical Center Patients

Location:  The diagnostic electron microscope (EM) is located in Room 2A09 (outside Autopsy Room) and this service is part of the Ultrastructural Pathology Section, Laboratory of Pathology.

For in-house surgical pathology, if tissue is fixed in glutaraldehyde for EM, this should be recorded in the gross description.

Tissue will be processed to the final "grid" stage in all cases that are submitted for priority or routine examination. Cases submitted as "block only" will not be processed beyond the block stage, unless further examination by light microscopy indicates that EM is necessary. In those cases, the resident should inform the EM staff about the need for further processing.

If after review of the H&E stained slides, it is decided that EM is not necessary to establish a diagnosis, then the EM staff should be notified accordingly and the gross description should be modified to indicate in the final report that tissue is submitted in glutaraldehyde for block only.

When the tissue is processed for EM but the case is to be signed out provisionally on the basis of the light microscopic material, the Surgical Pathology Report should indicate that tissue has been processed for EM and an Electron Microscopic Report will follow. At this time the EM staff should be notified in person or by phone. Eventually, a copy of the Surgical Pathology report will be given to EM staff so that they will be familiar with the provisional light microscopic diagnosis and questions to be answered by electron microscopy.

When EM prints are available for review, the resident and/or Surgical Pathology staff will meet with the EM staff and jointly review the light microscopy, EM prints, and thick sections. They will correlate and integrate the light microscopic and EM findings and they will arrive at a final pathologic diagnosis. When this happens before a Surgical Pathology Report is signed out, the EM findings may be incorporated in the Surgical Pathology Report which will be co-signed by all parties involved--at a minimum ,this will include the EM staff, the Surgical Pathology staff, and the Surgical Pathology resident. This report will contain the EM accession number in the microscopic description. When a Surgical Pathology Report has already been issued, or the parties involved have agreed to present the EM findings separately, an Electron Microscopic Report will be issued as a supplement to the Surgical Pathology Report.

Copies of the EM Report will be filed and bound in the Surgical Pathology Office and will be filed attached to the main Surgical Pathology Report. Two (2) copies from each EM Report or Surgical Pathology Report containing EM findings will be forwarded to the EM section to be filed accordingly in the EM files.

If EM is required for submitted surgical specimens, the same guidelines as described above will be followed.

Submitting a Specimen

Specimens for diagnostic EM require specific fixation, trimming, and a separate diagnostic EM face sheet. All necessary materials are located both in the Frozen Section Room, 2C533, and in Room 2A10 (across the hall from Room 2A09). Specifically, glutaraldehyde fixative in labeled small glass vials is kept refrigerated in both rooms. Diagnostic EM face sheets are kept in manila pouches in both rooms.

When submitting tissue for EM, please note the following:

  • Tissues fixed in B5 or frozen tissues are unsuitable for EM examination. If you anticipate even the slightest possibility that EM may be needed in the future, fix small pieces in glutaraldehyde. One piece of 1mm3 volume may be enough for EM examination when much tissue is not available.

  • Small pieces of tissue, representative of the tumor or lesion, should be minced in a small pool of glutaraldehyde with a razor or scalpel. Pieces of tissue larger than 1mm3 fixed in glutaraldehyde will not be optimal for EM examination, because glutaraldehyde fixes only from the surface and at a depth of 1mm.

  • Submit all small round cell tumors (Ewing's sarcoma, PNET, rhabdomyosarcoma) for EM, even if this is a repeat biopsy.

  • Before placing tissue in fixative, consider other diagnostic techniques which might also be useful, such as:
    • Tissue culture--fresh, sterile, or uncontaminated tissue required.
    • Tissue for lymphoid cell markers--lymphomas in particular.
    • Tissue snap-frozen in OCT for immunocytochemistry and molecular diagnostic studies.
    • Bulk frozen tissue--for biochemical extraction or assay, such as estrogen receptors, hormone content, or future study.

  • Choice of tissue is important; sampling is the single greatest problem in diagnostic EM. When in doubt, submit tissue from several areas, in separate vials (A,B,C, etc.), with explanatory note in space provided on form.

  • Tissue in fixative should be submitted within 24 hours and preferably within the hour to prevent overfixation. All subsequent trimming and processing will be handled by us.

  • Be sure to fill out face sheet with the following information:
    • Patient's name.
    • Surgical pathology number, if possible.
    • Brief explanation of diagnostic problem and origin of tissue submitted.
    • Time and date placed in fixative.

  • The additional space for type of handling gives four (4) options:
    • Rush--as fast as humanly possible; same working day, if submitted by 8:30 AM, or next morning if submitted by noon. This requires pre-arrangement with the lab and should be used with caution.
    • Priority--results always available same week, and usually within 2 days.
    • Routine--results usually available within 8-10 days. If evaluation of H&E slides proves EM unnecessary, notify the EM lab immediately.
    • Block only--embedded but not sectioned until requested. Very useful for study or research cases, teaching cases, or especially potential diagnostic cases awaiting results of light microscopy. If a "block only" case needs to be handled as a "priority" or "routine" case after review of H&E slides, notify the EM lab immediately.
Role of the Resident

The resident facilitates the ultrastructural interpretation of cases by supplying information on the EM request form, by tracking down additional information if required, and by furnishing light microscopy slides to the EM staff. The light microscopic slides are critical to:

  • Identify the pathologic process in question (e.g., viral-mediated cell injury vs. new growth (tumor)).
  • Identify the tissue received and processed for EM as representative of the tissue in question (e.g., normal tissue adjacent to tumor vs. tumor).
  • Provide the starting point for the differential diagnosis in tumor cases (e.g., Is the tumor within the class of small round cell tumors or spindle cell tumors?).

The resident is invited to look at the tissue in the electron microscope and transmit the diagnosis to the senior staff, especially in cases requiring the most rapid diagnosis.

Otherwise, EM staff will meet with the resident (and senior staff member, as appropriate) to jointly review the light and electron microscopic findings in detail. This should provide in-depth teaching exposure, augmented by periodic Wednesday and/or Friday teaching conferences during the year.

Teaching cases that demonstrate the utility of diagnostic EM are available for review by the residents. Contact Dr. Tsokos to obtain these cases.
