Q

Which one of the listed statements is the best histologic definition of an
abscess?

A circumscribed collection of neutrophils with necrotic cellular debris
A localized defect that results from the sloughing of necrotic inflammatory tissue
from the surface of an organ
A localized proliferation of fibroblasts and small blood vessels
An aggregate of two or more activated macrophages
The excessive secretion of mucus from a mucosal surface

A

a. A circumscribed collection of neutrophils with necrotic cellular debris

An abscess is a localized collection of neutrophils and necrotic debris. It is basically a localized form of suppurative (purulent) inflammation, which is associated with pyogenic bacteria and is characterized by edema fluid admixed with neutrophils and necrotic cells (liquefactive necrosis or pus).

Q

The cardinal sign of inflammation called rubor is mainly the result of:

Decreased interstitial hydrostatic pressure
Decreased vascular permeability of capillaries
Increased vascular permeability of venules
Vasoconstriction of muscular arteries
Vasodilation of arterioles

A

e. Vasodilation of arterioles

Inflammation can be defined as the reaction of vascularized living tissue to local injury.
Celsus originally described four cardinal signs of inflammation: rubor (redness), tumor
(swelling), calor (heat), and dolor (pain). Virchow later added a fifth sign, loss of function
(functio laesa).
Redness (rubor) and heat (calor) are primarily the result of increased blood flow secondary
to vasodilation of arterioles.

Q

A 57-year-old male presents with signs of fatigue that are the result of
anemia. Workup reveals that his anemia is the result of bleeding from a colon cancer located in the sigmoid colon. The lesion is resected and at the time of surgery no metastatic disease is found. Which of the listed
markers would be most useful for future follow-up of this patient for the evaluation of possible metastatic disease from his colon cancer?

α fetoprotein (AFP)
Carcinoembryonic antigen (CEA)

Carcinoembryonic antigen (CEA) is a glycoprotein associated with many cancers including adenocarcinomas of the colon, pancreas, lung, stomach, and breast. It is used clinically to follow up patients with certain malignancies, such as colon cancer,
and to evaluate them for recurrence or metastases.

An 87-year-old male develops worsening heart failure. Workup reveals
decreased left ventricular filling due to decreased compliance of the left
ventricle. Two months later the patient dies, and postmortem sections

interstitium of his heart. When viewed under polarized light, this material
displays an apple-green birefringence. What is the correct diagnosis?

Amyloidosis
Glycogenosis
Hemochromatosis

A

Amyloidosis

The histologic diagnosis of amyloid is based solely on its special staining characteristics. It stains pink with the routine hematoxylin and eosin stain, but, with Congo red stain, amyloid stains dark red and has an apple-green birefringence when viewed under polarized light.

A

Quality control

Quality Control (QC) is a system of routine technical activities to assess and maintain the
quality of the inventory as it is being compiled. It is performed by personnel compiling the
inventory. The
QC system is designed to:
1. Provide routine and consistent checks to ensure data integrity, correctness, and
completeness;
2. Identify and address errors and omissions;
3. Document and archive inventory material and record all QC activities.
QC activities include general methods such as accuracy checks on data acquisition and
calculations, and the use of approved standardized procedures for emission and removal
calculations, measurements, estimating uncertainties, archiving information and reporting.
QC activities also include technical reviews of categories, activity data, emission factors,
other estimation parameters, and methods.
Quality Assurance (QA) is a planned system of review procedures conducted by personnel
not directly involved in the inventory compilation/development process. Reviews,
preferably by independent third parties, are performed upon a completed inventory
following the implementation of QC procedures.

EPIDEMIOLOGICAL TRIAD
REMEMBER “AHE” - Agent, Host and Environment
A number of models of disease causation have been proposed. Among the simplest of these is the EPIDEMIOLOGICAL TRIAD OR TRIANGLE, the traditional model for infectious disease.
The triad consists of an external agent, a susceptible host, and an environment that brings the host and agent together. In this model, disease results from the interaction between the agent and the susceptible host in an environment that supports transmission of the agent from a source to that host.
