⩥ pityriasis rosea.
Answer: A common skin problem that causes a rash. Occurs at any age
that most often in ages of 10 and 35. It may be caused by a virus
⩥ pityriasis rosea observation.
Answer: The rash often begins with a single, round or oval, pink patch
that is scaly with a raised border (herald patch). The size of the patch
ranges from 2 cm (0.8 in.) to 10 cm (3.9 in.). The larger patches are
more common. Days to weeks later, salmon-colored, 1 cm (0.4 in.) to 2
cm (0.8 in.) oval patches appear in batches on the abdomen, chest, back,
arms, and legs. Patches sometimes spread to the neck but rarely to the
face.
Patches on the back are often vertical and angled to form a "Christmas
tree" or "fir tree" appearance.
Mild itching is a problem for about half of the people who get the rash.
The rash usually lasts 6 to 8 weeks, but it can last up to several months.
⩥ pityriasis rosea diagnosis.
Answer: Your doctor will diagnose pityriasis rosea by looking at the
rash. Diagnosis can be hard when only the herald patch is visible,
because the condition is often mistaken for ringworm or eczema at this
time. After the rash appears, diagnosis is generally clear.
,If the diagnosis is unclear, your doctor may do a potassium hydroxide
(KOH) test to make sure the rash is not caused by a fungal infection. A
skin sample may be taken from the infected area and examined under the
microscope (biopsy). If the diagnosis is unclear in a sexually active
person, a test for syphilis is often done.
⩥ pityriasis rosea treatment.
Answer: There is no treatment necessary. It will last for several weeks.
The patient may use lotions. A corticosteroid may be used to relieve
itching and reduce the rash
⩥ Innate immunity.
Answer: The natural epithelial barrier that offers resistance. In outer
layer specialized epithelium, including the skin and mucosal services, is
relatively resistant to most environmental hazards and resistant infection
with disease causing microorganisms. If the barrier is damaged a highly
efficient local and systemic response (inflammation) is mobilized to
limit the extent of the damage, protect against infection, and initiate
repair of the damaged tissue
⩥ Adaptive immunity.
Answer: Inflammation associated with infection usually initiates an
adaptive process that results in a long-term and very effective immunity
to the infecting microorganism, Adaptive immunity is relatively slow to
develop but has memory and more rapidly targets and eradicates a
,second infection with a particular disease-causing microorganism. The
information presented in this chapter introduces
⩥ Inflammatory response.
Answer: Innate immunity includes two lines of defense: natural barriers
and inflammation (Table 7-1). Natural barriers are physical, mechanical,
and biochemical barriers at the body's surfaces and are in place at birth
to prevent damage by substances in the environment and thwart
infection by pathogenic microorganisms. If the surface barriers are
breached, the second line of defense, the inflammatory response, is
activated to protect the body from further injury, prevent infection of the
injured tissue, and promote healing. The inflammatory response is a
rapid activation of biochemical and cellular processes that is relatively
nonspecific, with similar responses being initiated against a wide variety
of causes of tissue damage.

includes anatomic barriers (i.e., skin and mucous membranes), cells and
secretory molecules or cytokines (e.g., lysozymes, low pH of stomach
and urine), and ciliary activity Protection includes vascular responses,
cellular components (e.g., mast cells, neutrophils, macrophages),
secretory molecules or cytokines, and activation of plasma protein
systems Protection includes activated T and B lymphocytes, cytokines,
and antibodies
⩥ Inflammatory response upon injury.
Answer: Is activated to protect the body from further injury, prevent
infection of the injured tissue, and promote healing. Inflammatory
response is a rapid activation of biochemical and cellular processes that
is relatively nonspecific with similar responses being initiated against a
wide variety of causes of tissue damage.
