What factors can trigger Psoriasis?

These should be avoided as far as possible: Stress, infection
especially ear, nose, throat and bladder. Alcohol, nicotine, none
steroidal anti-inflammatory, Aspirin, local Trauma (Koebner phenom.)
as in scratches, operation scars, after severe sunburn. Malaria
prophylactics: Chloroquin, mefloquine, Lithium, Beta Blockers.

Oral steroids and potent topical cortisone may precipitate a more
severe form of psoriasis. Avoid oral cortisone as much as possible.

Some of the more common triggers include:

  • Changes in temperature or humidity
  • Chemical irritants (pesticides, alcohol, astringents, perfumes,
    soaps, detergents, etc.)
  • Physical irritants such as clothing, particularly wool and rough
    fabrics
  • Allergies (dust, pollen, mold, etc.)
  • Stress (emotional)  


Clinical presentations: May vary from small to large, typical to atypical
lesions involving scalp (dry, red, scaly to thick scabs, itching or non-
itching).

Individual lesions from a few millimeters to large areas covering most
of the body surface..Erythema, silvery scale and waxy scales.
Occasionally pustules present. The typical lesions on elbows, knees,
scalp and nails may remain permanently or may spread to full body
and severe extensive psoriasis, especially after triggering factors
Eczema - Psoriasis
What is Eczima or Psoriasis

Psoriasis & Eczema are  noncontiguous, lifelong skin diseases that
have been diagnosed in 4.5 million adults in Canada . While the causes
for these conditions are  not known, it is thought to be triggered by a
problem with the immune system. There also seems to be a genetic
component to these  conditions.

Plaque Psoriasis is the most common form of the disease. The skin
appears as raised, red patches or lesions covered with a silvery white
buildup of dead skin cells, called scale. Other forms of the disease can
cause small dot-like lesions (guttate), weeping lesions (pustular),
intense inflammation (inverse) and intense shedding and redness
(erythrodermic).

While Psoriasis & Eczema can appear anywhere on the body, it is most
commonly found on the scalp, knees, hands , elbows and torso. It
occurs equally in men and women and across nearly all races.

These conditions can cause mild to extreme physical discomfort, but
most sufferers are most affected by the social and emotional issues
associated with the disease. Many people are uncomfortable around
people with the disease, and some even avoid contact because they
mistakenly believe the lesions to be contagious. If the disease appears
in visible areas, it may make the person feel very uncomfortable to
appear socially.

Eczema is frequently referred to as atopic dermatitis or non-specific
dermatitis. This condition has a genetic basis. It often has no specific
etiology, but results from the interaction of multiple genes and is
triggered by external environmental factors. The greater the number of
atopic genes that are present, the less environmental initiators are
required to activate the disease.

The cells at the centre of the inflammation are called T lymphocytes.
Their presence represents the immune system’s reaction to the trigger
factors. Different individuals have unique etiologies or triggers that
result in a breakout of the rash.
Laser therapy

LLLT Studies have demonstrated that laser treatments improve or eliminate the appearance of Eczema
or Psoriasis and continue to improve over a period of time ranging from 3 to 6 months after the laser
treatment. Even those treatments that showed little if any initial improvement showed as much as a
50% improvement at their 6 month checkup.

The improvement is believed to be largely due to the laser’s stimulation of increased production of
collagen and elastin in the dermal (deeper) layer of the skin, where scaring is formed.

The laser's energy stimulates the scar tissue under the skin and causes the fibroblasts in the skin to
begin to divide again. The stimulation of the production of collagen, thickens the skin under the scars
until it closely resembles the surrounding normal skin.
A significant aspect of therapy is to determine the trigger factors and delete them from the environment.



Laser therapy is used to:

  • Increase the speed, quality and tensile strength
of tissue repair
  • Give pain relief
  • increases blood supply
  • stimulates the immune system
  • develops collagen and muscle tissue
  • helps develop new and healthy cells and
tissue
  • reduces inflammation
