Psoriasis is a chronic inflammatory dermatosis that can occur at any age and can affect both men and women.
Factors involved in the onset and worsening of this condition may be genetic predisposition (20-40% of cases), bacterial infections, Pytirosporum ovale infection, viral infections, drugs (lithium salts, beta blockers, NSAIDs, tetracyclines, amiodarone, digoxin, etc.), trauma, psychogenic factors (stress, emotional shocks), alcohol and smoking.
It represents 2/3 of the cases of psoriasis and is clinically manifested by the appearance of erythematous plaques covered with white-pearly, multi-layered scale that detaches easily.
Depending on the location, the following were highlighted:
- scalp psoriasis
- facial psoriasis
- fold psoriasis (reverse psoriasis)
- palmoplantar psoriasis
- mucosal psoriasis
The shape and size of the lesions were described:
- punctate psoriasis (squamous, millimeter lesions)
- follicular psoriasis (erythematous-squamous follicular papules, 2-4 mm in diameter)
- drip psoriasis - preceded by an infectious episode or vaccination
- psoriasis nevid
- numular psoriasis
- figured psoriasis
- psoriasis in plaques and placards
- universal psoriasis
The patients have an altered general condition, are feverish, have generalized and intense itching and massive flaking. The risk is dehydration, infections and vascular decompensation.
Arthropathic psoriasis (psoriatic arthritis)
Represents 5-7% of cases of psoriasis. It is more common in the age group between 36-45 years.
Types of arthropathic psoriasis
- asymmetric oligoarthritis
- dominant distal interphalangeal involvement
- arthropathic psoriasis of the mutilating type
- symonegative symmetric polyarthritis
- axial shape (spondylitis / sacroiliitis)
- form with isolated spinal cord injury
- mixed, peripheral and axial shape
The treatment will be adapted to the form of the disease, the duration of evolution and the age of the patient.
The aim will be to eliminate the triggering or aggravating factors, to mentally rebalance the patient (psychotherapy), as well as to adopt a hypocaloric and / or hypoglycemic regime.
Local treatment (topical) consists in the administration of Keratolytics, cignolin, tars, dermatocorticoids, vitamin D3 derivatives, calcineurin inhibitors.
