2. IMMUNOLOGY: DEFINITION
Study of;
1. the protection of the human
body from foreign
macromolecules or invading
organisms.
2 responses of the human body
to them.
3. OUR FIRST LINE OF DEFENSE:
These cells include;
1. macrophages
2. neutrophils
that engulf foreign organisms and
kill them without the need for
antibodies.
4. OUR SECOND LINE OF DEFENSE:
The specific or adaptive immune
system
Which may take days to respond
to a primary invasion (that is
infection by an organism that has
not hitherto been seen).
5. THE IMMUNE SYSTEM
1. Innate or Non-specific
Immune System
1. Adaptive or Specific Immune
System
9. MAIN FUNCTION OF THE IMMUNE
SYSTEM
The ability to distinguish
between self and non-self is
necessary to protect the
organism from invading
pathogens and to eliminate
modified or altered cells (e.g.
malignant cells).
10. MAIN FUNCTION OF THE IMMUNE
SYSTEM
It is important to remember
that infection with an organism
does not necessarily mean
diseases, since the immune
system in most cases will be
able to eliminate the infection
before disease occurs.
11. CAUSES OF A DISEASE:
When the bolus of infection is
high.
The virulence of the microrganism
is great.
When immunity is compromised.
12. NON – SPECIFIC SPECIFIC
IMMUNITY IMMUNITY
Response is antigen- Response is antigen-
dependent dependent
There is immediate There is lag time between
maximal response exposure and maximal
response
Non-antigen specific Antigen - specific
Exposure results in no Exposure results in
immunologic memory immunologic memory
13. INNATE / NON-SPECIFIC
IMMUNITY
The elements of the innate
(non-specific) immune system
include;
1. anatomical barriers
2. secretory molecules
3. cellular components
14. ANATOMICAL BARRIERS TO
INFECTIONS
1. MECHANICAL FACTORS
The skin acts as our first line of
defense against invading
organisms.
Movement due to cilia or
peristalsis helps to keep air
passages and the gastrointestinal
tract free from microorganisms.
15. ANATOMICAL BARRIERS TO
INFECTIONS
1. MECHANICAL FACTORS
The flushing action of tears and
saliva helps prevent infection of
the eyes and mouth.
The trapping effect of mucus that
lines the respiratory and
gastrointestinal tract helps protect
the lungs and digestive systems
from infection.
16. ANATOMICAL BARRIERS TO
INFECTIONS
2. CHEMICAL FACTORS
Fatty acids in sweat inhibit the growth of
bacteria.
Lysozyme and phospholipase found in
tears, saliva and nasal secretions can
breakdown the cell wall of bacteria
and destabilize bacterial membranes.
17. ANATOMICAL BARRIERS TO
INFECTIONS
2. CHEMICAL FACTORS
The low pH of sweat and gastric
secretions prevents growth of
bacteria.
Defensins (low MW proteins) found in the
lung and gastrointestinal tract have
antimicrobial activity.
18. ANATOMICAL BARRIERS TO
INFECTIONS
3. BIOLOGICAL FACTORS
The normal flora of the skin and in the
gastrointestinal tract can
prevent the colonization of pathogenic
bacteria by;
1. secreting toxic substances
2. competing with pathogenic bacteria
for nutrients or attachment to cell
surfaces.
19. HUMORAL BARRIERS TO
INFECTIONS
Humoral factors play an important role
in inflammation, which is
characterized by edema and the
recruitment of phagocytic cells.
These humoral factors are found in
serum or they are formed at the site
of infection.
21. HUMORAL BARRIERS TO
INFECTIONS
1. Complement System
Once activated complement can lead
to;
a. increased vascular permeability
b. recruitment of phagocytic cells, c.
lysis
d. opsonization of bacteria
22. HUMORAL BARRIERS TO
INFECTIONS
2. Coagulation System
Some products of the coagulation
because of their ability to;
a. increase vascular permeability b.
act as chemotactic agents for
phagocytic cells.
23. HUMORAL BARRIERS TO
INFECTIONS
2. Coagulation System
In addition, some of the products of
the coagulation system are directly
antimicrobial.
For example, beta-lysin, a protein
produced by platelets during
coagulation can lyse many Gram
positive bacteria by acting as a
cationic detergent.
24. HUMORAL BARRIERS TO
INFECTIONS
2. Lactoferrin and Transferrin
By binding iron, an essential nutrient
for bacteria, these proteins limit
bacterial growth.
25. HUMORAL BARRIERS TO
INFECTIONS
3. Interferons
Interferons are proteins that can limit
virus replication in cells.
4. Lysozyme
Lysozyme breaks down the cell wall of
the bacteria.
26. HUMORAL BARRIERS TO
INFECTIONS
5. Interleukin – 1
Il-1 induces fever and the production of
acute phase proteins, some of which
are antimicrobial because they can
opsonize bacteria.

31. CELLULAR BARRIERS TO
INFECTIONS
Part of the inflammatory
response is the recruitment of
polymorphonucleareosinophile
s and macrophages to sites of
infection.
32. CELLULAR BARRIERS TO
INFECTIONS
1. NeutrophilsPolymorphonuclear cells
are recruited to the site of infection
where they phagocytose invading
organisms and kill them intracellularly.
In addition, PMNs contribute to collateral
tissue damage that occurs during
inflammation.
33. CELLULAR BARRIERS TO
INFECTIONS
2. Macrophages and Newly
Recruited Monocytes
Differentiate into macrophages,
also function in phagocytosis
and intracellular killing of
microorganisms.
34. CELLULAR BARRIERS TO
INFECTIONS
3. Natural Killers
(NK)andLymphokine Activated
Killer (LAK) cells
NK and LAK cells can nonspecifically kill virus
infected and tumor cells.
These cells are not part of the inflammatory
response but they are important in
nonspecific immunity to viral infections
and tumor surveillance.
37. KILLER (K) CELLS
Killer(K) cells are not a
morphologically distinct type of
cell.
Rather a K cell is any cell that
mediates antibody-dependent
cellular cytotoxicity (ADCC).
38. KILLER (K) CELLS
InADCC antibody acts as a link to
bring the K cell and the target cell
together to allow killing to occur.
K cells have on their surface an Fc
receptor for antibody and thus they
can recognize, bind and kill target
cells coated with antibody.
39. KILLER (K) CELLS
Killercells which have Fc receptors
include NK, LAK, and macrophages
which have an Fc receptor for IgG
antibodies and eosinophils which
have an Fc receptor for IgE
antibodies.
41. PHAGOCYTOSIS AND
INTRACELLULAR KILLING
A. PHAGOCYTIC CELLS
1. Neutrophiles / Polymorphonuclear (PMN)
Cells
1.1 primary or azurophilic granules, which are
abundant in young newly formed PMNs, contain
cationic proteins and defensins that can kill
bacteria, proteolytic enzymes like elastase, and
cathepsin G to breakdown proteins, lysozyme to
break down bacterial cell walls, and
characteristically, myeloperoxidase, which is
involved in the generation of bacteriocidal
compounds.
42. PHAGOCYTOSIS AND
INTRACELLULAR KILLING
A. PHAGOCYTIC CELLS
1. Neutrophiles / Polymorphonuclear (PMN)
Cells
1. 2 secondary or specific granule
These contain lysozyme, NADPH oxidase
components, which are involved in the generation
of toxic oxygen products, and characteristically
lactoferrin, an iron chelating protein and B12-
binding protein.
43. PHAGOCYTOSIS AND
INTRACELLULAR KILLING
A. PHAGOCYTIC CELLS
2. Monocytes / Macrophages
Macrophages are phagocytic cells that have a
characteristic kidney-shaped nucleus.
They can be identified morphologically or by
the presence of the CD14 cell surface marker.
44. OXYGEN –INDEPENDENT MECHANISMS
OF INTRACELLULAR KILLING
EFFECTOR FUNCTION
MOLECULE
Cationic Proteins Damage to microbial
(including cathepsin) membranes
Lysozyme Splits mucopeptide in
the bacterial cell wall
Lactoferrin Deprives proliferating
bacteria of iron
Proteolytic and Digestion of killed
Hydrolytic Enzymes organisms
45. RESPONSE OF PHAGOCYTES TO
INFECTION
Circulating PMNs and monocytes respond to
danger (SOS) signals generated at the site of an
infection.
SOS signals include;
1. N-formyl-methionine containing peptides
released by bacteria
2. clotting system peptides
3. complement products
4. cytokines released from tissue macrophages
that have encountered bacteria in tissue
46. RESPONSE OF PHAGOCYTES TO
INFECTION
Some of the SOS signals stimulate
endothelial cells near the site of the
infection to express cell adhesion
molecules such as;
1. ICAM-1
2. selectins
which bind to components on the surface
of phagocytic cells and cause the
phagocytes to adhere to the endothelium.
47. RESPONSE OF PHAGOCYTES TO
INFECTION
Vasodilators produced at the site of
infection cause the junctions between
endothelial cells to loosen and the
phagocytes then cross the endothelial
barrier by “squeezing” between the
endothelial cells in a process called
“DIAPEDESIS.”
49. RESPONSE OF PHAGOCYTES TO
INFECTION
Once in the tissue spaces some of the
SOS signals attract phagocytes to the
infection site by chemotaxis (movement
toward an increasing chemical
gradient).
50. RESPONSE OF PHAGOCYTES TO
INFECTION
The SOS signals also activate the
phagocytes, which results in;
1. increased phagocytosis
2. intracellular killing of the invading
organisms.

IMMUNE SYSTEM
ALLERGIES:
Asthma (Bronchial, Exercise Induced)
Dermatitis (Contact and Atopic)

outdoor allergies and asthma.
66. ALLERGY: PROGNOSIS
Most
allergies can be easily treated with
medication.
Some children may outgrow an
allergy, especially food allergies.
However, once a substance has triggered an
allergic reaction, it usually continues to
affect the person.
67. ALLERGY: PROGNOSIS
Allergyshots / Immunology are most
effective when used to treat people with hay
fever symptoms and severe insect sting
allergies.
Theyare not used to treat food allergies
because of the danger of a severe reaction.

disease involving inflammation of the
urethra, eyes and joints).
152. LABORATORY EXAMS and
TESTS: ARTHRITIS
HLA tissue typing
The genetic marker HLA-B27 is almost
always present in people with either of
these diseases.
153. LABORATORY EXAMS and
TESTS: ARTHRITIS
Erythrocyte sedimentation rate
Also called ESR or ―sed rate,‖ this test
measures how fast red blood cells cling
together, fall and settle (like sediment)
in the bottom of a glass tube over the
course of an hour.
The higher the rate, the greater the
amount of inflammation.
154. LABORATORY EXAMS and
TESTS: ARTHRITIS
Lyme Serology
This test detects an immune response
to the infectious agent that causes
Lyme disease and thus can be used to
confirm a diagnosis of the disease.
155. LABORATORY EXAMS and
TESTS: ARTHRITIS
Skin Biopsy
Taking small samples of skin and
examining them under a microscope
can help doctors diagnose forms of
arthritis that involve the skin, such as
lupus, vasculitis (inflammation of the
blood vessels) and psoriatic arthritis.
156. LABORATORY EXAMS and
TESTS: ARTHRITIS
Muscle biopsy
By going a little deeper into the tissue
than with the skin biopsy, the surgeon
can take a sample of muscle to be
examined for signs of damage to the
muscle fibers.
Findings can confirm a diagnosis of
polymyositis or vasculitis.
157. LABORATORY EXAMS and
TESTS: ARTHRITIS
Joint fluid tests
In this procedure, which is similar to drawing
blood, the doctor inserts a needle into a joint
space and removes fluid.
An examination of the fluid may reveal uric
acid crystals, confirming a diagnosis of gout
or bacteria, suggesting that the joint
inflammation is caused by infection.
158. LABORATORY EXAMS and
TESTS: ARTHRITIS
Muscle Enzymes Test ( CPK, Aldolase)
Such tests can measure the amount of
muscle damaged as well as how
effective medication has been in
reducing the inflammation that caused
the muscle damage.
159. RHEUMATOID ARTHRITIS
An autoimmune disease in which
the body's immune system attacks
itself.
The pattern of joints affected is
usually symmetrical, involves the
hands and other joints and is worse
in the morning.
160. RHEUMATOID ARTHRITIS
Rheumatoid arthritis is also a
systemic disease, involving other
body organs, whereas osteoarthritis
is limited to the joints.
Overtime, both forms of arthritis
can be crippling.
161. RHEUMATOID ARTHRITIS:
CAUSES
Causeof RA is unknown. It is an
autoimmune disease, which means
the body's immune system
mistakenly attacks healthy tissue.
RA
can occur at any age, but is
more common in middle age.
Women get RA more often than
men.
163. RHEUMATOID ARTHRITIS:
SYMPTOMS
1. Morning stiffness, which lasts
more than 1 hour, is common.
Joints may feel warm, tender, and
stiff when not used for an hour.
2. Joint pain is often felt on the
same joint on both sides of the
body.
164. RHEUMATOID ARTHRITIS:
SYMPTOMS
3. Chest pain when taking a breath (pleurisy)
4. Dry eyes and mouth (Sjogren syndrome)
5. Eye burning, itching, and discharge
6. Nodules under the skin (usually a sign of
more severe disease)
7. Numbness, tingling, or burning in the
hands and feet
8. Sleep difficulties
165. RHEUMATOID ARTHRITIS:
TREATMENT
RA usually requires lifelong
treatment, including medications,
physical therapy, exercise,
education, and possibly surgery.
Early, aggressive treatment for RA
can delay joint destruction.
166. OSTEOARTHRITIS: DEFINITION
Associated with the aging process
and can affect any joint.
The cartilage of the affected joint is
gradually worn down, eventually
causing bone to rub against bone.
Bony spurs develop on the
unprotected bones causing pain and
inflammation.
169. OSTEOARTHRITIS: CAUSES
Aging.
The water content of the cartilage
increases and the protein makeup of
cartilage degenerates.
Repetitive use of the joints over the
years causes damage to the cartilage
that leads to joint pain and swelling.
173. GOUT: DEFINITION
It can cause an attack of
sudden burning pain, stiffness,
and swelling in a joint, usually a
big toe.
These attacks can happen over
and over unless gout is treated.
174. GOUT: DEFINITION
Over time, they can
harm the joints,
tendons, and other
tissues.
Gout is most common in
men.
175. GOUT: CAUSES AND RISK FACTORS
High levels of uric acid in the
blood, which crytallize in the joints.
Overweight
High alcohol consumption
Diet rich in fish and meat (due to
purine content)
Diuretics
176. GOUT: THE THREE STAGES
Stage One: High Blood Acid levels
The uric acid level in the blood may be higher
than normal, but there are no symptoms of
gout.
High uric acid in the blood (hyperuricemia)
may never progress beyond this stage, and
symptoms of gout may never develop.
Some people may have kidney stones before
having their first attack of gout.
177. GOUT: THE THREE STAGES
Stage Two: Episodes of acute gouty
arthritis separated by periods without
symptoms.
This stage is also called intercritical or interval
gout.
Uric acid crystals begin to form in the joint
fluid, usually in one joint-most commonly the
big toe-and the body often responds with a
sudden inflammatory reaction: a gout attack.
178. GOUT: THE THREE STAGES
Stage Two: Episodes of acute gouty
arthritis separated by periods without
symptoms.
Although the big toe is the most common site
for a gout attack, gout may develop in other
joints, including the knee, ankle, and joints in
the foot, wrist, and fingers.
After the gout attack is over, the affected joint
and surrounding tissues feel normal within
days until the next attack, which often occurs
within 2 years
179. GOUT: THE THREE STAGES
Stage Two: Episodes of acute gouty
arthritis separated by periods without
symptoms.
For many people this period becomes
progressively shorter as attacks occur
more often.
Later attacks may be more severe, last
longer, and involve more than one joint.
180. GOUT: THE THREE STAGES
Stage Three: Chronic Tophaceous Gout
If gout symptoms have occurred off and
on without treatment for several years,
they may become ongoing (chronic)
and frequently affect more than one
joint.
There may no longer be periods of time
between attacks.
181. GOUT: THE THREE STAGES
Stage Three: Chronic Tophaceous Gout
By this time, enough uric acid crystals have
accumulated in the body to form gritty
nodules called tophi.
When located just under the surface of the
skin, these deposits are usually firm and
movable. The overlying skin may be thin and
red. Tophi that are very near the skin may
appear cream-colored or yellow.
182. GOUT: THE THREE STAGES
Stage Three: Chronic Tophaceous Gout
At first, tophi are usually found on or near the
elbow, over the fingers and toes, or on the
outer edge of the ear.
183. GOUT: THE THREE STAGES
Stage Three: Chronic Tophaceous Gout
Progressive crippling and destruction of
cartilage and bone is possible.
This stage of gout is uncommon because of
advances in the early treatment of gout.
184. GOUT: NON-PHARMACOLOGICAL
MANAGEMENT
Eat
moderate amounts of a healthy
mix of foods.
Avoid regular daily intake of meat,
seafood, and alcohol (especially
beer).
Drink plenty of water and other
fluids.
185. RHEUMATIC FEVER: DEFINITION
An inflammatory disease that
may develop after an infection
with group A Streptococcus
bacteria (such as strep throat or
scarlet fever).
The disease can affect the
heart, joints, skin, and brain.
186. RHEUMATIC FEVER: CAUSES,
INCIDENCE, RISK FACTORS
Common worldwide and is
responsible for many cases of
damaged heart valves.
Rheumatic fever mainly affects
children ages 5 -15, and occurs
approximately 14-28 days after
strep throat or scarlet fever.
187. RHEUMATIC FEVER: SYMPTOMS
Abdominal pain
Fever
Heart (cardiac) problems, which may
not have symptoms, or may result in
shortness of breath and chest pain
Joint pain, arthritis (mainly in the
knees, elbows, ankles, and wrists)
Joint swelling; redness or warmth
188. RHEUMATIC FEVER: SYMPTOMS
Nosebleeds (epistaxis)
Skin nodules
Skin rash (erythemamarginatum)
1. Skin eruption on the trunk and
upper part of the arms or legs
2. Eruptions that look ring-shaped or
snake-like
189. RHEUMATIC FEVER: SYMPTOMS
Sydenham chorea (emotional
instability, muscle weakness and
quick, uncoordinated jerky movements
that mainly affect the face, feet, and
hands)
190. RHEUMATIC FEVER: MAJOR
CRITERIAS FOR DIAGNOSIS
1. Arthritis in several large joints
(polyarthritis)
2. Heart inflammation (carditis)
3. Nodules under the skin (subcutaneous skin
nodules)
4. Rapid, jerky movements (chorea,
Sydenham chorea)
5. Skin rash (erythemamarginatum)
192. RHEUMATIC FEVER: LABORATORY
EXAMS AND TESTS
Blood test for recurrent strep infection (such as an
ASO test)
Antistreptolysin O (ASO) titer is a blood test to
measure antibodies against streptolysin O, a
substance produced by group A Streptococcus
bacteria.
Complete blood count
Electrocardiogram
Sedimentation rate (ESR)
193. RHEUMATIC FEVER: LABORATORY
EXAMS AND TESTS
Sedimentation rate (ESR)
Normal Values
Adults (Westergren method):
Men under 50 years old: less than 15 mm/hr
Men over 50 years old: less than 20 mm/hr
Women under 50 years old: less than 20 mm/hr
Women over 50 years old: less than 30 mm/hr
195. RHEUMATIC FEVER: TREATMENT
Low doses of antibiotics (such as
penicillin, sulfadiazine, or
erythromycin) over the long term to
prevent strep throat from returning.
Anti-inflammatory (Aspirin or
Corticosteroids)
196. RHEUMATIC FEVER: PROGNOSIS
If rheumatic fever returns, the
doctor may recommend the patient
take low-dose antibiotics
continually, especially during the
first 3 -5 years after the first episode
of the disease.
Heart complications may be severe,
particularly if the heart valves are
involved.
197. RHEUMATIC FEVER:
COMPLICATIONS
Arrhythmias
Damage to heart valves (in particular, mitral
stenosis and aortic stenosis)
Endocarditis
Heart failure
Pericarditis
Sydenham chorea
198. RHEUMATIC FEVER: PREVENTION
The most important way to
prevent rheumatic fever is by
getting quick treatment for
strep throat and scarlet fever.
201. ACNE: DEFINITION
Common skin disease that causes
pimples.
Pimples form when hair follicles under
the skin clog up.
Most pimples form on the face, neck,
back, chest and shoulders.
Anyone can get acne, but it is common
in teenagers and young adults. It is not
serious, but it can cause scars.
202. ACNE: BODY PARTS AFFECTED
Acne typically appears on your
face, neck, chest, back and
shoulders, which are the areas
of the skin with the largest
number of functional oil glands.
203. ACNE: CAUSES
Hormonal changes (during puberty
and pregnancy.
Overproduction of sebum / oil
Irregular shedding of dead skin cells
resulting in irritation of the hair
follicles of skin
Buildup of bacteria
205. ACNE: FACTORS THAT WORSENS IT
Hormones
Androgens are hormones that
increase in boys and girls during
puberty and cause the sebaceous
glands to enlarge and make more
sebum.
Hormonal changes related to
pregnancy and the use of oral
contraceptives can also affect
sebum production.
206. ACNE: FACTORS THAT WORSENS IT
Certain medications
Drugs containing;
1. corticosteroids
2. androgens
3. lithium
are known to cause acne.
207. ACNE: FACTORS THAT WORSENS IT
Diet
Studies indicate that certain dietary
factors, including dairy products
and carbohydrate-rich foods —
such as bread, bagels and chips,
which increase blood sugar — may
trigger acne.
208. ACNE: DIFFERENT FORMS
NON-INFLAMMATORY LESIONS
1. Comedones (Whiteheads and
Blackheads)
Created when the openings of hair
follicles become clogged and blocked
with oil secretions, dead skin cells
and sometimes bacteria.
209. ACNE: DIFFERENT FORMS
NON-INFLAMMATORY LESIONS
1. Comedones (Whiteheads and
Blackheads)
When comedones are open at the skin
surface, they're called blackheads
because of the dark appearance of the
plugs in the hair follicles.
210. ACNE: DIFFERENT FORMS
NON-INFLAMMATORY LESIONS
1. Comedones (Whiteheads and
Blackheads)
When comedones are closed, they're
called whiteheads — slightly raised,
skin-colored bumps.
211. ACNE: DIFFERENT FORMS
INFLAMMATORY LESIONS
1. Papules - small raised bumps that
signal inflammation or infection in the
hair follicles. Papules may be red and
tender.
212. ACNE: DIFFERENT FORMS
INFLAMMATORY LESIONS
2. Pustules (pimples) - are red, tender
bumps with white pus at their tips.
213. ACNE: DIFFERENT FORMS
INFLAMMATORY LESIONS
3. Nodules - are large, solid, painful
lumps beneath the surface of the skin.
They're formed by the buildup of
secretions deep within hair follicles.
214. ACNE: DIFFERENT FORMS
INFLAMMATORY LESIONS
4. Cysts - painful, pus-filled lumps
beneath the surface of the skin. These
boil-like infections can cause scars.
215. ACNE ROSACEA: DEFINITION
A long-term disease that affects
the skin and sometimes the eyes.
It causes redness and pimples.
Rosaceais most common in
women and people with fair skin.
It usually starts between age 30
and 60.
216. ACNE ROSACEA: SYMPTOMS
Frequent redness (flushing) of the face.
Most redness is at the center of the
face (forehead, nose, cheeks, and chin).
A burning feeling and slight swelling.
Small red lines under the skin.
217. ACNE ROSACEA: SYMPTOMS
Constant redness along with bumps on
the skin. Sometimes the bumps have
pus inside (pimples), but not always.
Solid bumps on the skin may later
become painful.
Inflamed eyes/eyelids.
Swollen, red, large bumpy nose.
218. ACNE ROSACEA: SYMPTOMS
Thicker skin.
The skin on the
forehead, chin, cheeks, or other areas
can become thicker because of
rosacea.
219. ACNE ROSACEA: CAUSES
When blood vessels expand too
easily, causing flushing.
People who blush a lot may be more
likely to get rosacea.
Hereditary
220. ACNE ROSACEA: CAUSES
Patients’skin with rosacea were to
have high levels of cathelicidins,
peptides with antimicrobial and pro-
inflammatory properties that protect
the skin against infection.
221. ACNE ROSACEA: CAUSES
Levelsof stratum corneumtryptic
enzyme or SCTE — the enzyme
responsible for cleaving the inactive
cathelicidins into their active form —
were also elevated in people with the
disease.
A flaw in the immune system
contributes to this disease.
222. ACNE ROSACEA: FACTORS THAT
MAKE IT WORSE
Heat (including hot baths)
Heavy exercise
Sunlight
Winds
Very cold temperatures
Hot or spicy foods and drinks
Drinking alcohol
Menopause
Emotional stress
Long-term use of steroids on the face
223. ACNE ROSACEA: TREATMENT
Adapalene Cream or Gel (Differin)
A moderator of differentiation of
follicular epithelial
cells, keratinization, and
inflammatory processes.
It has both exfoliating and anti-
inflammatory effects.
224. ACNE ROSACEA: TREATMENT
Electro surgery and Laser
surgery
Improves skin appearance with
less scarring.
225. ACNE ROSACEA: TREATMENT
Scraping off the excess skin
tissue from a swollen, bumpy
nose.

severe acne.
Isotretinoin – for deep, cystic acne.
Oral Contraceptives -a combination
of norgestimate and ethinylestradiol
(Ortho Tri-Cyclen, Previfem), can
improve acne in women.
231. ACNE: COSMETIC / SURGICAL
TREATMENTS
Laser / Light Therapy
Laser treatment – damages the oil
glands, to produce lesser oil.
Light therapy – targets the bacteria
that causes acne inflammation
232. ACNE: COSMETIC / SURGICAL
TREATMENTS

doing strenous work.
236. PSORIASIS: DEFINITION
A skin disease that causes scaling and
inflammation (pain, swelling, heat, and
redness).
Skincells grow deep in the skin and
slowly rise to the surface.
237. PSORIASIS: DEFINITION
Thisprocess is called cell turnover,
and it takes about a month.
Withpsoriasis, it can happen in just a
few days because the cells rise too fast
and pile up on the surface.
238. PSORIASIS: DEFINITION
A chronic, autoimmune disease that
appears on the skin.
Itoccurs when the immune system
sends out faulty signals that speed up
the growth cycle of skin cells.
Psoriasis is not contagious.
239. PSORIASIS: FIVE TYPES
Plaque Psoriasis (psoriasis vulgaris)
The most prevalent form of the disease.
About 80 percent of those who have
psoriasis have this type.
It is characterized by raised, inflamed, red
lesions covered by a silvery white scale.
It is typically found on the elbows, knees,
scalp and lower back.
241. PSORIASIS: FIVE TYPES
Guttate Psoriasis
Aform of psoriasis that often starts in
childhood or young adulthood.
This form of psoriasis appears as small,
red, individual spots on the skin.
Guttatelesions usually appear on the trunk
and limbs. These spots are not usually
as thick as plaque lesions.
243. PSORIASIS: FIVE TYPES
Inverse Psoriasis
Found in the armpits, groin, under the
breasts, and in other skin folds around
the genitals and the buttocks.
This type of psoriasis appears as bright-
red lesions that are smooth and shiny.
Inverse psoriasis is subject to irritation
from rubbing and sweating because of
its location in skin folds and tender
areas.
245. PSORIASIS: FIVE TYPES
Pustular Psoriasis
Primarily seen in adults, pustular psoriasis is
characterized by white blisters of
noninfectious pus (consisting of white blood
cells) surrounded by red skin.
246. PSORIASIS: FIVE TYPES
Pustular Psoriasis
Triggers include irritating topical agents,
overexposure to UV light, pregnancy,
systemic steroids, infections, stress and
sudden withdrawal of systemic medications
or potent topical steroids.
247. PSORIASIS: FIVE TYPES
Erythrodermic Psoriasis
An inflammatory form of psoriasis that
affects most of the body surface.
It may occur in association with von
Zumbuschpustular psoriasis.
The reddening and shedding of the skin are
often accompanied by severe itching and
pain, heart rate increase, and fluctuating
body temperature.
248. PSORIASIS: FIVE TYPES
Erythrodermic Psoriasis
Triggers include;
a. abrupt withdrawal of a systemic psoriasis
treatment including cortisone
b. allergic reaction to a drug resulting in the
Koebnerresponse

prescription topical treatments to
control psoriasis lesions.
OTC topicals containing salicylic
acid and coal tar.
252. PSORIASIS: PHARMACOLOGICAL
TREATMENT
Phototherapy / Light Therapy with
Psoralen
It involves exposing the skin to
ultraviolet light on a regular basis
and under medical supervision.
Consistency is the key for the
success of this treatment.
253. PSORIASIS: PHARMACOLOGICAL
TREATMENT
Sunlight
Start with five to 10 minutes of
noontime sun daily.
Gradually increase exposure time
by 30 seconds if the skin tolerates
it.
To get the most from the sun, all
affected areas should receive equal
and adequate exposure.
255. PSORIASIS: PHARMACOLOGICAL
TREATMENT
Laser treatments
2. Pulsed Laser - uses a dye and
different wavelength of light than the
excimer laser or other UVB-based
treatments, pulsed dye lasers destroy
the tiny blood vessels that contribute
to the formation of psoriasis lesions.

Notas del editor
These invaders include viruses, bacteria, protozoa or even larger parasites. In addition, we develop immune responses against our own proteins (and other molecules) in autoimmunity and against our own aberrant cells in tumor immunity.
Our first line of defense against foreign organisms are barrier tissues such as the skin that stop the entry of organism into our bodies.If, however, these barrier layers are penetrated, the body contains cells that respond rapidly to the presence of the invader. (READ SLIDE)Immediate challenge also comes from soluble molecules that deprive the invading organism of essential nutrients (such as iron) and from certain molecules that are found on the surfaces of epithelia, in secretions (such as tears and saliva) and in the blood stream. This form of immunity is the innate or non-specific immune system that is continually ready to respond to invasion.
In the specific immune system, we see the production of antibodies (soluble proteins that bind to foreign antigens) and cell-mediated responses in which specific cells recognize foreign pathogens and destroy them.READ SLIDEThe response to a second round of infection is often more rapid than to the primary infection because of the activation of memory B and T cells.
Innate immune system is our first line of defense against invading organisms Adaptive immune system acts as a second line of defense and also affords protection against re-exposure to the same pathogen.
Each of the major subdivisions of the immune system has both cellular and humoral components by which they carry out their protective function (Figure 1). In addition, the innate immune system also has anatomical features that function as barriers to infection. Although these two arms of the immune system have distinct functions, there is interplay between these systems (i.e., components of the innate immune system influence the adaptive immune system and vice versa). Although the innate and adaptive immune systems both function to protect against invading organisms, they differ in a number of ways. The adaptive immune system requires some time to react to an invading organism, whereas the innate immune system includes defenses that, for the most part, are constitutively present and ready to be mobilized upon infection. Second, the adaptive immune system is antigen specific and reacts only with the organism that induced the response. In contrast, the innate system is not antigen specific and reacts equally well to a variety of organisms. Finally, the adaptive immune system demonstrates immunological memory. It “remembers” that it has encountered an invading organism and reacts more rapidly on subsequent exposure to the same organism. In contrast, the innate immune system does not demonstrate immunological memory.
All cells of the immune system have their origin in the bone marrow and they include myeloid (neutrophils, basophils, eosinpophils, macrophages and dendritic cells) and lymphoid (B lymphocyte, T lymphocyte and Natural Killer) cells (Figure 2), which differentiate along distinct pathways (Figure 3). The myeloid progenitor (stem) cell in the bone marrow gives rise to erythrocytes, platelets, neutrophils, monocytes/macrophages and dendritic cells whereas the lymphoid progenitor (stem) cell gives rise to the NK, T cells and B cells. For T cell development the precursor T cells must migrate to the thymus where they undergo differentiation into two distinct types of T cells, the CD4+ T helper cell and the CD8+ pre-cytotoxic T cell. Two types of T helper cells are produced in the thymus the TH1 cells, which help the CD8+ pre-cytotoxic cells to differentiate into cytotoxic T cells, and TH2 cells, which help B cells, differentiate into plasma cells, which secrete antibodies.
The main function of the immune system is self/non-self discriminationREAD SLIDE Since pathogens may replicate intracellularly (viruses and some bacteria and parasites) or extracellularly (most bacteria, fungi and parasites), different components of the immune system have evolved to protect against these different types of pathogens.
Although the immune system, for the most part, has beneficial effects, there can be detrimental effects as well. READ SLIDEDuring inflammation, which is the response to an invading organism, there may be local discomfort and collateral damage to healthy tissue as a result of the toxic products produced by the immune response. In addition, in some cases the immune response can be directed toward self tissues resulting in autoimmune disease.
Among the mechanical anatomical barriers are the skin and internal epithelial layers, the movement of the intestines and the oscillation of broncho-pulmonary cilia. Associated with these protective surfaces are chemical and biological agents.
The epithelial surfaces form a physical barrier that is very impermeable to most infectious agents. Skin….READ SLIDE The desquamation of skin epithelium also helps remove bacteria and other infectious agents that have adhered to the epithelial surfaces
The anatomical barriers are very effective in preventing colonization of tissues by microorganisms. However, when there is damage to tissues the anatomical barriers are breached and infection may occur. Once infectious agents have penetrated tissues, another innate defense mechanism comes into play, namely acute inflammation.READ SLIDE
OPSONIZATION - The process by which bacteria are altered in such a manner that they are more readily and more efficiently engulfed by phagocytes.
Depending on the severity of the tissue injury, the coagulation system may or may not be activated.READ SLIDECHEMOTAXIS - A response of motile cells or organisms in which the direction of movement is affected by the gradient of a diffusible substance. Differs from chemokinesis in that the gradient alters probability of motion in one direction only, rather than rate or frequency of random motion.
These cells are the main line of defense in the non-specific immune system
PMNs are motile phagocytic cells that have lobed nuclei. They can be identified by their characteristic nucleus or by an antigen present on the cell surface called CD66. They contain two kinds of granules the contents of which are involved in the antimicrobial properties of these cells.READ SLIDE
Unlike PMNs they do not contain granules but they have numerous lysosomes which have contents similar to the PNM granules.
DIAPEDESIS –CHEMOTAXIS -
The immune system normally protects the body against harmful substances, such as bacteria and viruses. It also reacts to foreign substances called allergens, which are generally harmless and in most people do not cause a problem.But in a person with allergies, the immune response is oversensitive. When it recognizes an allergen, the immune system launches a response. Chemicals such as histamines are released. These chemicals cause allergy symptoms.
INSECT VENOM: Bedbug bite; Bee sting; Bites - insects, bees, and spiders; Black widow spider bite; Brown recluse bite; Flea bite; Honey bee or hornet sting; Lice bites; Mite bite; Scorpion bite; Spider bite; Wasp sting; Yellow jacket sting
CERTAIN MEDICINES MAY CAUSE AN INCREASE IN EOSINOPHILS:Amphetamines (appetite suppressants)Certain laxatives containing psylliumCertain antibioticsInterferonTranquilizers
Eosinophils become active when you have certain allergic diseases, infections, and other medical conditions.
CUSHING’S DISEASE - Cushing’s disease is a condition in which the pituitary gland releases too much adrenocorticotropic hormone (ACTH). The pituitary gland is an organ of the endocrine system.Cushing's disease is a form of Cushing syndrome.CausesCushing's disease is caused by a tumor or excess growth (hyperplasia) of the pituitary gland. This gland is located at the base of the brain.People with Cushing's disease have too much ACTH. ACTH stimulates the production and release of cortisol, a stress hormone. Too much ACTH means too much cortisol.Cortisol is normally released during stressful situations. It controls the body's use of carbohydrates, fats, and proteins and also helps reduce the immune system's response to swelling (inflammation).NORMAL EOSINOPHIL WBC COUNT: Less than 350 cells per microliter (cells/mcL).
This reduces the amount of air that can pass by.
In sensitive people, asthma symptoms can be triggered by breathing in allergy-causing substances (called allergens or triggers).
ASA-INDUCED ASTHMA ATTACKS ACCOUNTS ONLY TO 2.7%ALTERNATIVE TO ASA ARE THE COXIBS (COX – 2 INHIBITORS) such as CELECOXIB ( but ADR’s include heart attacks and stroke)
Most people with asthma have attacks separated by symptom-free periods. Some people have long-term shortness of breath with episodes of increased shortness of breath. Either wheezing or a cough may be the main symptom.Asthma attacks can last for minutes to days, and can become dangerous if the airflow is severely restricted.

Blood gases is a measurement of how much oxygen and carbon dioxide is in your blood. It also determines the acidity (pH) of your blood.
There is no special preparation. If you are on oxygen therapy, the oxygen concentration must remain constant for 20 minutes before the test.How the Test Will FeelYou may feel brief cramping or throbbing at the puncture site.
Spirometry is frequently used to evaluate lung function in people with obstructive or restrictive lung diseases such as asthma or cystic fibrosis.PEAK FLOW MEASUREMENTS – a peak flow of 50% to 80% - shows moderate asthma attack. Below 50% shows severe asthma attack.

They also can be used just before exercising to help prevent asthma symptoms that are caused by exercise.Tell your doctor if you are using quick-relief medicines twice a week or more to control your asthma symptoms. Your asthma may not be under control, and your doctor may need to change your dose of daily control drugs.
Smoking outside the house is not enough. Family members and visitors who smoke outside carry smoke residue inside on their clothes and hair -- this can trigger asthma symptoms.
There are several ways to do a skin biopsy. Most procedures can be easily done in outpatient medical offices or your doctor's office.Which procedure you have depends the location, size, and type of lump or sore. You will receive some type of numbing medicine (anesthetic) before any type of skin biopsy.Punch biopsies are most often used for deeper skin spots or sores. Your doctor removes a small round piece of skin (usually the size of a pencil eraser) using a sharp, hollow instrument. If a large sample is taken, the area may be closed with stitches.An excisional biopsy is done to remove the entire lesion. A numbing medicine is injected into the area. Then the entire lump, spot, or sore is removed, going as deep as needed to get the whole area. The area is closed with stitches. Pressure is applied to the area to stop any bleeding. If a large area is biopsied, a skin graft or flap of normal skin may be used to replace the skin that was removed.An incisional biopsy takes a piece of a larger growth for examination. The area is injected with a numbing medicine. A piece of the growth is cut and sent to the lab for examination. You may have stitches, if needed. The rest of the growth can be treated after the diagnosis is made.our doctor may order a skin biopsy if you have signs or symptoms of:Chronic or acute skin rashesNoncancerous (benign) growthsSkin cancerOther skin conditionsRisks may include:InfectionScar (keloids)You will bleed slightly during the procedure.

Cartilage normally protects a joint, allowing it to move smoothly. Cartilage also absorbs shock when pressure is placed on the joint, such as when you walk. Without the normal amount of cartilage, the bones rub together, causing pain, swelling (inflammation), and stiffness.
Rheumatoid arthritis is different from osteoarthritis, the common arthritis that often comes with older age. RA can affect body parts besides joints, such as your eyes, mouth and lungs. RA is an autoimmune disease, which means the arthritis results from your immune system attacking your body's own tissues.
Muscles that have been damaged by some rheumatic diseases release certain enzymes into the blood, and these enzymes can be detected through blood tests.
Osteoarthritis (also sometimes referred to as “degenerative joint disease” or “degenerative arthritis”)
Over time, joints may lose their range of motion and may become deformed.
Osteoarthritis is a chronic disease of the joint cartilage and bone, often thought to result from "wear and tear" on a joint, although there are other causes such as congenital defects, trauma and metabolic disorders. Joints appear larger, are stiff and painful and usually feel worse the more they are used throughout the day.
You'll likely be diagnosed with rheumatic fever if you meet two major criteria, or one major and two minor criteria, and have signs that you've had a previous strep infection.
An increased ESR rate may be due to some infections, including:Body-wide (systemic) infectionBone infectionsInfection of the heart or heart valvesRheumatic feverSevere skin infections, such as erysipelasTuberculosis
Stress does not cause acne, but can make it worse.
Acne develops when an oily substance that lubricates your hair and skin (sebum) plugs the hair follicles. Bacteria can trigger inflammation and infection.
These lines show up when blood vessels under the skin get larger. This area of the skin may be somewhat swollen, warm, and red
Researchers funded in part by the National Institute of Arthritis and Musculoskeletal and Skin Diseases December 2007 research.
RETINOIDS etc. - They work by promoting cell turnover and preventing plugging of the hair follicles. A number of topical antibiotics also are available. They work by killing excess skin bacteria.
USE OR ORAL CONTRACEPTIVESThe most serious potential complication is a slightly increased risk of heart disease, high blood pressure and blood clots.
hey may cause temporary, severe redness, scaling and blistering, and long-term discoloration of the skin.
. The word guttate is from the Latin word meaning "drop."
Guttate psoriasis often comes on quite suddenly. A variety of conditions can bring on an attack of guttate psoriasis, including upper respiratory infections, streptococcal throat infections (strep throat), tonsillitis, stress, injury to the skin and the administration of certain drugs including antimalarials and beta-blockers.
. It can be more troublesome in overweight people and those with deep skin folds.
ay be localized to certain areas of the body, such as the hands and feet, or covering most of the body. It begins with the reddening of the skin followed by formation of pustules and scaling.
People experiencing the symptoms of erythrodermic psoriasis flare should go see a doctor immediately. Erythrodermic psoriasis causes protein and fluid loss that can lead to severe illness. The condition may also bring on infection, pneumonia and congestive heart failure. People with severe cases of this condition often require hospitalization.
SKIN INJURY due to vaccinations, sunburns and scratches can triggerKOEBNER PHENOMENON – MINOR SKIN TRAUMAS SUCH AS SCRAPED KNEES, GARDEN SCRAPES AND BUG BITEShe Koebner phenomenon is named after Dr. Heinrich Koebner, a German dermatologist who noticed the phenomenon in the 19th century. A slight scratch won't cause koebnerization, but a cut or bite that damages the dermis (the layer of skin below the surface) may begin to show lesions.
Topical treatments—medications applied to the skin—are usually the first line of defense in treating psoriasis. Topicals slow down or normalize excessive cell reproduction and reduce the inflammation associated with psoriasis.
UVB and UVA TREATMENTS - Present in natural sunlight, UVB is an effective treatment for psoriasis. UVB penetrates the skin and slows the growth of affected skin cells. Psoralen is a light sensitizing medicationDuring UVB treatment, your psoriasis may worsen temporarily before improving. The skin may redden and itch from exposure to the UVB light. To avoid further irritation, the amount of UVB administered may need to be reduced. Occasionally, temporary flares occur with low-level doses of UVB. These reactions tend to resolve with continued treatment.
Remember to wear sunscreen on areas of your skin unaffected by psoriasis.
They are usually used for individuals with moderate to severe psoriasis and psoriatic arthritis. Systemic medications are also used in those who are not responsive or are unable to take topical medications or UV light therapy
Interleukins-12/23 are also cytokines which are thought to promote the inflammation associated with psoriasis.
