T/F: Psoriasis is primarily caused by an overproduction of melanin in the skin
FALSE!
Psoriasis is primarily an autoimmune disorder involving the DYSFUNCTION of the Immune System and inflammation in the skin, rather than an overproduction of melanin.
The primary mechanism of psoriasis involves the autoimmune process affecting T-cells and TNF dysfunction.
T/F: Trauma to the skin, such as cuts or burns, can trigger the development of psoriasis plaques at the site of injury.
True!
T/F: Excessive sun exposure is a known trigger for psoriasis flare-ups.
True!!
** While moderate sun exposure may benefit some individuals with psoriasis,
excessive sun exposure can trigger or worsen psoriasis flare-ups in others.

B) Oral antihistamines
C) Addition of a vitamin D analogue
D) Phototherapy
C) Addition of a vitamin D analogue

b) Diprosalic (betamethasone dipropionate/salicylic acid)
c) Silkis (calitriol)
d) Dovobet Gel, Dovobet Ointment, Enstilar Foam (calcipotriol/betamethasone dipropionate)
b) Diprosalic (betamethasone dipropionate/salicylic acid)

… Moderate- to ultra-high-potency [topical corticosteroid]
T/F: Monotherapy with topical corticosteroids is a less expensive approach initially for treating scalp psoriasis
True!
Since safety profiles between corticosteroids and vitamin D analogues are said to be similar and the fact that combination products provided only a marginal benefit over corticosteroids alone, monotherapy with topical corticosteroids is a reasonable, less expensive approach initially

a) Coal tar
b) Salicylic acid 3-10%
c) Diprosalic (betamethasone dipropionate/salicylic acid)

T/F: Vehicles such as lotion, solution, gel, or foam are easier to apply to hair-bearing scalp and may increase patient acceptance and adherence in scalp psoriasis treatment.
True!
Vehicles such as lotion, solution, gel, or foam are indeed easier to apply to hair-bearing scalp and may increase patient acceptance and adherence in scalp psoriasis treatment.
T/F: Psoriasis is relatively uncommon on the face in comparison to other affected sites (elbows, knees, scalp, sacral area).
True! While it may be seen on the upper forehead as an extension of scalp psoriasis, if there are suspicions of psoriasis on the face, should consider other diagnostic considerations.
HC 1% Cream or Ointment BID might be adequate to treat for some cases of psoriasis that is located on the face region… If this doesn’t work, what can we add to treatment regiment?
