PASI score

PASI stands for Psoriasis Area and Severity Index. PASI includes the amount of body surface area that is affected by psoriasis in addition to three major symptoms: redness, inflammation, and the thickness of the scale on the skin. A patient is given a PASI score from 0-72 where 0 means no psoriasis and 72 means the most severe psoriasis. A PASI score is given to a patient before treatment and then after treatment to determine the effectiveness of the therapy. The goal of successful psoriasis treatment is to reduce the PASI score as close to 0 (no psoriasis) as possible.

Ultraviolet info seems self-contradictory

Ultraviolet wavelengths are subdivided into UVA (380–315 nm), UVB (315–280 nm), and UVC (< 280 nm). Ultraviolet B (UVB) (315–280 nm) is absorbed by the epidermis and has a beneficial effect on psoriasis. Narrowband UVB (311 to 312 nm), is that part of the UVB spectrum that is most helpful for psoriasis.

Query: If UVA is from 380-315 nm, it includes 311-312 nm. So how come Narrowband UV (311 to 312 nm) is supposed to be UVB instead of UVA?

Answer: 380-315nm does not included 311-312nm. 311-312 is less than 315.

Mention the generic (calcitriol) along with the patented (calcipotriol)?

Moisturizers and emollients such as mineral oil, petroleum jelly, calcipotriol or calcitriol, and decubal (an oil-in-water emollient) were found to increase the clearance of psoriatic plaques. Emollients have been shown to be even more effective at clearing psoriatic plaques when combined with phototherapy.^[1] However, certain emollients have no impact on psoriasis plaque clearance or may even decrease the clearance achieved with phototherapy. The emollient salicylic acid is structurally similar to para-aminobenzoic acid (PABA), commonly found in sunscreen, and is known to interfere with phototherapy in psoriasis. Coconut oil, when used as an emollient in psoriasis, has been found to decrease plaque clearance with phototherapy.^[1] Medicated creams and ointments applied directly to psoriatic plaques can help reduce inflammation, remove built-up scale, reduce skin turnover, and clear affected skin of plaques. Ointment and creams containing coal tar, dithranol, corticosteroids (i.e. desoximetasone), fluocinonide, vitamin D₃ analogs (for example, calcipotriol or calcitriol), and retinoids are routinely used. The use of the finger tip unit may be helpful in guiding how much topical treatment to use.^[2]^[3]

picture introduction

hello, I was thinking the most distinctive quality of psoriasis is hyperkeratosic white plaques on the scalp or in elbows / knees, on a red - inflammatory plaque, and thus a picture of a person with inflammatory plaques on their back seems to be a bit away from the definition. i fell like a picture that fits the more specific definition would be better Psixtras (talk) 22:18, 17 September 2024 (UTC)[reply]

Reference cleanup

I completed a maintenance update to the References section to address several script warnings related to missing metadata and deprecated parameters in {{cite journal}}: Empty citation (help) templates.

Changes include:

Resolving maintenance messages
Adding missing PMIDs or issue numbers where available
Removing deprecated or bot-triggering parameters
Standardizing journal, volume, and page formats
Ensuring all list-defined references render cleanly

No article content was changed; this was strictly a technical cleanup to improve citation reliability and consistency per MOS:CITE and MEDRS formatting expectations. Orange Jones (talk) 21:49, 14 November 2025 (UTC)[reply]

I'm sorry to say that your edits have made a severe mess of the references in the article, with many missing/undefined references and many unused list-defined references. Can you please look at and address all the red errors that have appeared in the References section? Thanks, Wham2001 (talk) 08:45, 15 November 2025 (UTC)[reply]

Lead cleanup

I made a set of small updates to the lead and infobox to improve clarity, consistency, and alignment with current MEDMOS guidelines. The main changes were:

modernizing the infobox to include standard parameters (ICD codes, OMIM, MeSH, etc.)
streamlining some of the infobox fields for readability
updating the first sentence of the lead to reflect current terminology (e.g., “immune-mediated”)
improving flow and reducing redundancy in the opening paragraph
keeping all substantive content the same as reflected in the body of the article

These edits were intended to help the lead better summarize the article in line with Wikipedia’s style guidelines. Please feel free to adjust, refine, or expand as needed. Collaboration is welcome, and if anything looks off or could be better supported, I’m happy to discuss further. Orange Jones (talk) 00:51, 16 November 2025 (UTC)[reply]
