Article Synopsis
- TSLP, a cytokine associated with allergic reactions, may work with CD40L to increase IL-23 production in psoriasis, a skin condition caused by an inappropriate immune response.
- The study involved 53 psoriasis patients, classified by severity based on the PASI score, and compared their serum TSLP levels to a control group of 53 healthy individuals.
- Results indicated significantly higher TSLP levels in psoriasis patients compared to controls, with levels correlating positively with disease severity, suggesting TSLP could be a potential marker for psoriasis severity.
Trichoscopy corresponds to the scalp, and hair dermoscopy has been increasingly used as an aid in the diagnosis, follow-up, and prognosis of hair disorders. Trichoscopy represents a valuable link between clinical and histological diagnosis. Tinea capitis (TC) and alopecia areata (AA) are considered the most common causes of hairless patches of the scalp in pediatrics.

Skin needling is a technique that uses a sterile dermaroller to puncture the skin and release growth factors. The combination of skin needling and PRP could enhance the efficacy of both modalities.

Recently, it has been reported that vascular endothelial growth factor (VEGF), a potent angiogenic factor, is overexpressed in keloid tissue and may have a potential role in its evolution.
Methods: Twenty patients with keloids were included in this study and classified into two groups according to the treatment received: intralesional triamcinolone acetonide 20 mg/mL (group 1) and cryotherapy spray technique (group 2).
