PSORIASIS: HOW TO MAKE A HAND DIAGNOSIS VIA
'MULTI-PERSPECTIVE PALM READING'!

Multi-perspective palm reading.

How to make a Palm Reading Assessment
for PSORIASIS?
Key-elements of the hand in Psoriasis in a nutshell: multiple skin problems (scales or plagues are typical), often featured with multiple nail abnormalities (nail pitting + onycholysis are most common).

An advanced hand diagnosis for Psoriasis requires a person to have multiple significant hand markers that follow the MAJOR REQUIREMENT + the additional requirements described below:

MAJOR REQUIREMENT: The person requires to have significant hand markers for Psoriasis that relate to SKIN QUALITY (= hand perspective 6) + one of the other dimensions of the hand

- ADDITIONAL REQUIREMENT A: The person requires to have at least 3 hand markers that relate to SKIN QUALITY (= hand perspective 6)

- ADDITIONAL REQUIREMENT B: The person requires to have at least 2 hand markers that relate to FINGERNAILS (= hand perspective 2), MOTORICS (= hand perspective 7), or FINGER MORPHOLOGY (= hand perspective 3).

- ADDITIONAL REQUIREMENT C: The person requires to have at least one hand marker in the palm (or back of the hand) + at least one hand marker in the fingers.

(More specifications will follow soon)



IMPORTANT: Even when all above REQUIREMENTS are fullfilled, then one can speak of a 'confirmed' hand diagnosis for Psoriasis - NOTICE: most cases of psoriasis are diagnosed clinically!

Some of the 24 significant hand markers for Psoriasis that are listed below became known in medical science as a 'physical minor anomaly' (such as the simian crease).
But in general most of these individual hand markers can usually be described as harmless body characteristics - except for the markers described for perspectives 2, 6 and 7.





- List of 24 hand markers for Psoriasis -


 • Hand perspective 1 - HAND SHAPE:
- (No elements identified yet)

• Hand perspective 2 - FINGERNAILS:
- Nail pitting: 20 pits in one person is typical (more than 60 pits per person is unlikely to be found in the absence of psoriasis);
- White color due to air bubble/detachment from nail bed (onycholysis);
- Horizontal ridging;
- Horizontal transverse lines (Beau lines);
- Nail deformation: nail plate weakening, crumbling (onychodystrophy);
- Discoloration: yellow, yellow brownish (oil drop), salmon patch;
- Red spots in lunula;
- Splinter hemorrhages;
- Thickening of the nail plate due to fast nail growth;
- Thickening of the hyponychium (subungual hyperkeratosis);
- Fungal infection (onychomycosis);
- Nail fold infection (paronychia).

• Hand perspective 3 - FINGER MORPHOLOGY:
- Sausage finger: inflammation of entire digit (dactylitis).

• Hand perspective 4 - MAJOR LINES:
- Simian crease.

• Hand perspective 5 - DERMATOGLYPHICS:
- (No elements identified yet)

• Hand perspective 6 - SKIN QUALITY:
- Thickened skin;
- Red skin;
- Skin scales;
- Skin plaques: skin scales larger than 1 cm in diameter - typically manifesting on bony areas, or in the palm (Psoriasis Vulgaris);
- Punctate bleeding spots below skin scales (Auspitz's Sign);
- Formation of skin scales around injured skin (Koebner Phenomenon);
- Blisters surrounded by red skin (Pustular Psoriasis);
- Tripe palms (acanthosis palmaris).

• Hand perspective 7 - MOTORICS:
- Pain due to nail changes: resulting in restrictions during daily activities;
- Problems related to the distal interphalangeal joints.


NOTICE: About 1% to 3% of the world population has psoriasis.

THE FAMOUS 'SIMIAN LINE' (SINGLE PALMAR CREASE) IS ONLY A MINOR KEY-ELEMENT FOR THE HAND IN PSORIASIS


Hand Diagnostics:
the Simian Line & Psoriasis!

Various studies around the world have proven that the simian line is more often seen among diabetics than in the general population (about 3% of the healthy population has a simian line in at least one hand). This implicates that the simian line is much more important in the genetic syndromes (e.g. Down syndrome & Fragile-X syndrome) than it is in psoriasis. Therefore a simian line can only play a role in a hand diagnosis for Psoriasis if multiple significant hand markers are seen in two other perspectives (MOTORICS + FINGERNAILS).

This raises the question: 'how can the simian line serve as a diagnostic marker specific for Psoriasis?'

HAND LINES IN PSORIASIS:

• 1 - Simian crease
Prevalence: Psoriasis patients: 15.91 %; controls: 8.98 % 1,2
