Skin IL-17A and IFN-γ Production Correlate with Disease Severity in Patients with Psoriasis and Streptococcal Infection.

Psoriasis is a multisystemic inflammatory disorder mainly involving the skin and joints, whose etiopathogenesis is still not completely understood. An association with streptococcal throat infection has been suggested. We aim to investigate a correlation between IL-17A and IFN-γ production by T cells infiltrating skin lesions and PASI in 313 patients with psoriasis, compared with that in 252 healthy controls.

Clinical characteristics of itch in cutaneous lupus erythematosus: A prospective, multicenter, multinational, cross-sectional study.

Objective: Pruritus is an important symptom frequently accompanying various inflammatory skin conditions and some recent data indicated that it may be associated with autoimmune connective tissue diseases. The aim of this study was to assess the frequency and clinical presentation of itch in CLE.

Methods: A multinational, prospective, cross-sectional study was performed to assess the prevalence, intensity and clinical characteristic of pruritus in various subtypes of CLE.

New Insight in Noninvasive Rejuvenation: The Role of a Rhodamine-Intense Pulsed Light System.

Rhodamine-intense pulsed light (r-IPL) is a noncoherent, noncollimated, polychromatic light energy optimized for a double-peak wavelength emission, ranging between 550-680 and 850-1200 nm. Traditional IPL works within visible and infrared spectra, targeting hemoglobin and melanin, are effective to treat rosacea and pigmentary disorders. r-IPL, a new technology in dermatology, emits high-intensity light with a wavelength peak similar to the one of the pulsed dye lasers, showing a good safety and efficacy profile in nonablative photorejuvenation.
