What are the steps in a CHRONIC VASCULAR RESPONSE?
|
-Body has numerous primary sensory neurons that responds to ROSACEA TRIGGERS
-Transient Receptor Potential Vanillloid(1), which are linked to ERYTHEMATOTELANGIECTATIC ROSACEA, are activated by rosacea triggers and cause a vasodilation response followed by a rapid recovery. -A pathological response leads to release neuropeptides. -The neuropeptides act as vasodilators, causing prolonged dilation of the blood vessels. -Resulting in warmth on skin, sustained flushing and facial erythema. |
CHRONIC VASCULAR RESPONSE.
|
|
What are the steps in the CHRONIC INFLAMMATORY RESPONSE?
|
-In rosacea affected skin toll-like receptors(2) are triggered and a chemical cascade occurs.
-White blood cells are sent to the pilosebaceous unit causing inflammation. -Then a proteases called kallikrein-5 is produced. -Kallikrein-5 break apart an antimicrobial peptide called cathelicidin LL-37 to create LL-37 peptide fragments. -Causing increase of white blood cells to pilosebaceous unit and increase of inflammation. |
CHRONIC INFLAMMATORY RESPONSE
|
|
WHAT ARE THE STEPS OF A HISTOPATHOLOGICAL CHANGES?
|
Once inflammation in facial skin is chronic
-Neutrophils leak into the dermis and destroy skin tissue. -Neutrophils then release destructive compounds: matrix-metalloproteinases, nitric-oxide, and reactive oxygen species. -Nitric Oxide causes vasodilation, which contributes to both chronic and inflammatory response in rosacea. -matrix-metalloproteinases and reactive oxygen species work in a chronic inflammatory response by weakening skin elements of collagen and elastin. -Causing skin elasticity of stratum corneum barrier. -Resulting in dry, scaling, flaking. |
Histopathological Response.
|
|
WHAT IS THE PATHOLOGY OF ROSACEA?
|
-Pathothology is not fully understood.
-Hyperactivity in skin neuronal sensory systems=vasodilation -Overactivity of the skins innate immune system=inflammation -Development of permanent vascular changes Resulting in complex dysregulation of inflammatory, neuronal, and vascular systems. |
|
|
WHAT ARE THE SIGNS OF "OCULAR" ROSACEA
|
-Burning eyes and stinging eyes.
-Watery blood shot eyes. -Dryness and Itching eyes. -Telangiectasia of conjunctiva. -Conjunctiva. -Blepharitis. |
|
|
WHAT ARE THE SIGNS OF PHYMATOUS ROSACEA?
|
-Thickening of skin and large pores.
-Rynophyma. -Also occur on the chin, cheeks, forehead, and ears. -Has been seen after or in combination with subtypes (1) and (2). |
|
|
WHAT ARE THE SIGNS OF "PAPULOPUSTULAR" ROSACEA?
|
-Persistent facial erythema.
-Popules and/or pustules in a central facial distribution. -Resembles acne however no comedones are present. -Secondary stinging or burning may occur. -May work with Erythematotelangiectasia. |
|
|
WHAT ARE THE SIGNS OF "ERYTHEMATOTELANGIECTATIC " ROSACEA?
|
PRIMARY
-Flushing 10 or more times. -Telangiectasia. -Persistent facial redness. SECONDARY -Dryness and Scaling. -Edema. -Stinging and burning. |
|
|
ACCORDING TO THE NATIONAL ROSACEA SOCIETY, WHAT ARE PHYCHOSOCIAL IMPACT OF ROSACEA AND PERCENTAGES?
|
-Adversely affected professional interaction (88%)
-Missed work (51%) -Denied promotion (41%) -Denied new job (39%) |
|
|
WHAT ARE THE PRIMARY AND SECONDARY SIGNS OF ROSACEA?
|
PRIMARY
-Transient erythema. -Non - Transient Erythema. -Popules and pustules -Telangiectasia SECONDARY -Edema -Dryness and Scaling -Burning and Stinging -Plagues |
|
|
ACCORDING TO THE NATIONAL ROSACEA SOCIETY, WHAT ARE THE (4) MOST COMMON TRIGGERS OF ROSACEA?
|
-Sun exposure (81%)
-Emotional (79%) -Hot Weather (75%) -Wind (57%) |
|
|
WHAT ARE THE TWO TYPES OF ROSACEA TRIGGERS?
|
-Environmental
-Ingested and Introgenic |
|
|
WHAT ARE THE FOUR TYPES OF ENVIRONMENTAL TRIGGERS?
|
-Weather
-Activity -Emotional -Temperature |
|
|
WHAT ARE THE INGESTED AND INTROGENIC TRIGGERS?
|
-Beverages
-Food -Drugs -Topical agents |
|
|
WHAT IS ROSACEA?
|
-Rosacea is a chronic inflammatory disease that affects the pilosebaceous unit.
-Blood vessels. -Causing facilities redness, Popules and pustules. |
|
|
WHAT IS THE EPITIOLOGY OF ROSACEA?
|
-16 million
-30's and 50's -4% African, Asia, Latino -Fitzpatrick phenotype 1 and 2 -Celtic, Northern European, Welsh |
|
|
WHAT ARE THE PRIMARY FUNCTION OF "TOLL-LIKE RECEPTORS(2)"
|
-Activation of TOLL-LIKE RECEPTORS ( 2 ) attract white blood cells to the pilosebaceous unit, causing inflammation.
-Activation of TOLL-LIKE RECEPTORS ( 2 ) increases production of proteases called kallikrein -5, which break apart cathelicidin LL-37 into inflammation triggering LL-37 fragments. |
|
|
WHAT ROLES DO NEUROPEPTIDES PLAY IN THE PATHOLOGY OF ROSACEA?
|
Neuropeptides act a vasodilators, causing prolonged dilation of blood vessels.
|
|
|
WHAT ARE CATHELICIDIN LL-37?
|
-Important molecule of innate immunity of the skin.
-CATHELICIDIN LL-37 splits into LL-37 fragments. -Affected skin is perceived as pathological. -Resulting in more inflammation. |
|
|
WHAT ARE PRIMARY SENSORY NEURONS?
|
-Primary sensory neurons can effect vascular change.
-TRANSIENT RECEPTOR POTENTIAL VANILLLOID are abundant. -Respond to temperature change,mechanical stimuli, and chemical stimuli. |
|
|
WHAT IS THE ROLE OF NITRIC OXIDE?
WHAT IS THE ROLE OF MATRIX-METALLOPROTEINASES? WHAT IS THE ROLE OF REACTIVE OXYGEN SPECIES? |
-Nitric Oxide promotes vasodilation contributing to chronic response.
