Lecture 1 Study Guide (Introduction to general & systemic path) Flashcards
The cause of a disease process:
Etiology
The mechanism of disease development:
Pathogenesis
The biochemical and structural changes induced in cells and organs:
Molecular and morphologic changes
The functional consequences of the morphologic changes:
Clinical manifestations
Any abnormal condition that may impair bodily function, cause discomfort, social problems, death, injuries, disabilities, disorders, syndromes, infections, alterations of behavior, and atypical variations of structure and function:
Disease
Disease may be classified as:
Intrinsic or extrinsic
Any type of clinical or molecular abnormality:
Lesion
A lesion that can occur due to irritation by biting cheek/tongue, a sharp tooth, etc.
traumatic ulcer
A white lesion that is irregular and thickened, often can’t find a reason for it:
Leukoplakia
Tooth lesion that may be xerostomia-related:
Carious lesion
Pigmented lesion, irregular in shape:
Melanoma
What is the most common intraoral site for melanoma in adults?
the palate
Basal cell carcinoma and sturge weber syndrome (encephotrigeminal angiomatosis) are both considered ____ lesions
Visible
-Visible lesion
-Associated with cognitive disorder
-1st and 2nd branch of trigeminal nerve affected:
Sturge weber syndrome (encephalotrigeminal angiomatosis)
Lesions that may be located deep within the body:
Invisible lesions
Invisible lesions may be ____ lesions or ____ lesions
Molecular lesions or biochemical lesions
Give two examples of invisible lesions that are located deep within the body:
- lung cancer
- breast cancer
Give three example of lesions that are invisible due to their molecular/biochemical basis:
- diabetes mellitus
- schizophrenia
- Phenylketonuria (PKU)- enzyme deficiency
-Invisible biochemical lesion
-Autosomal recessive disorder of phenylalanine metabolism
-mutation = phenylalanine hydroxylase (enzyme that converts phenylalanine to tyrosine)
-phenylalanine is toxic to the brain and causes profound, irreversible mental retardation (cognitive disorder)
-diagnosed by the Guthrie test (if positive remove phenylalanine from diet for life)
Phenylketonuria (PKU)
The name of the disease should give a clue to the ______ or _____ involved
Cause or organ system
Disease names may change overtime, such as:
- moniliasis =
- cementoma =
- odontogenic keratocyst =
- calcifying odontogenic cyst =
- geographic tongue =
- candidiasis
- cemento-osseous dysplasia
- keratocystic odontogenic tumor
- calcifying cystic odontogenic tumor
- erythema migrans
Diseases may have multiple names, such as:
- Paget disease of bone =
- geographic tongue =
- osteitis deformans
- erythema migrans
Diseases may be identified by eponyms, such as:
- Amyotrophic lateral sclerosis =
- Clotting factor 9 deficiency =
- Calcifying odontogenic cyst =
- Calcifying epithelial odontogenic tumor =
- Lou Gehrig Disease
- Christmas Disease
- Gorlin Cyst
- Pindborg Tumor
Diseases may be identified by acronyms such as:
- medication-related osteonecrosis of the jaw =
- odontogenic keratocyst =
- basal cell nevus syndrome =
- calcifying epithelial odontogenic tumor =
- MRONJ
- OKC
- BCNS
- CEOT
What is the difference between a sign and symptom of a disease?
Sign: objective, something you see
Symptom: subjective, something the patient tells you
Something the patient tells you (subjective):
Symptom
Something you see (objective):
Sign
A sign whose presence means that a particular disease is present beyond any doubt:
pathognomic
Diseases may vary in their prevalence- a rare disease with low prevalence is considered:
Orphan disease
- Marfan syndrome
- Cystic fibrosis
- Treacher Collins syndrome
- Sickle cell anemia
- Multiple endocrine neoplasia II
- Peutz Jegher syndrome
- Gorlin syndrome
- Ewing sarcoma
these are all examples of:
Orphan diseases
Refers to the disease state of an individual:
Morbidity
Refers to the incidence (number) of illness in a population:
Morbidity
Refers to the states of being mortal, or the incidence (number) of death in a population:
Mortality
Simultaneous presence of two or more medical conditions:
Comorbidity
The identifying nature or cause of some phenomenon:
Diagnosis
A prediction about how something will develop, prospect of recovery:
Prognosis
Label the following as sign or symptom:
- headache
- high blood pressure
- rash
- symptom
- sign
- sign/symptom
Categories of disease include: (6)
- developmental
- infectious
- neoplastic
- metabolic
- immune-mediated
- reactive
Define the category of disease:
-genetic, environmental
Developmental disease
Define the category of disease:
-bacteria, viruses, fungi, MMR
Infectious disease
Define the category of disease:
-benign, malignant (can metastasize)
Neoplastic disease
