Combined intralesional injection of tuberculin purified protein derivative plus cryotherapy versus each alone in the treatment of multiple common warts.
Different modalities are used for treatment of common warts, but none of them had been proved to be the best in achieving complete cure. We aim to compare the effect of cryotherapy, intralesional injection of tuberculin PPD and cryotherapy combined with intralesional injection of tuberculin PPD in the treatment of multiple common warts.

Macrophage Migration Inhibitory Factor in Vitiligo: Pathogenesis and Potential Therapeutic Aspects.
Vitiligo is an acquired skin disorder that is characterized by a gradual loss of skin pigmentation when melanocytes, the skin's pigment-producing cellsis lost. Pathogenicmechanisms are not well understood. Genetic, abnormal biochemical pathways, autoimmune, melanocyte adhesion deficits and nervous system imbalances are among the pathogenic triggers. Vitiligo lesions have also been shown to have macrophage infiltration.Macrophagemigration inhibitory factor (MIF) is a ... Read more

Diagnosis of onychomycosis clinically by nail Dermoscopy versus microbiological diagnosis.

To evaluate the diagnostic role of dermoscopy in onychomycosis and comparing its findings with microbiological results. Eighty patients with onychomycosis and 40 controls were studied for nail dermoscopic finding, and microbiological examinations in the form of microscopic examination by 20% KOH, Sabouraud dextrose ...

Assessment of the Effect of Metabolic Syndrome on the Autophagy Marker LC3 in Psoriasis Vulgaris Patients: A Cross-Sectional Study.
Purpose: Psoriasis vulgaris, one of the most prevalent chronic inflammatory skin diseases, is associated with metabolic syndrome (MetS). Autophagy, an intracellular degradation system is essential for cell survival and differentiation, and its dysfunction may contribute to metabolic diseases. A cross-sectional study was conducted on 38 psoriasis vulgaris patients and 16 healthy control subjects to 1) Assess immunohistochemical (IHC) expression of ... Read more

Lesional and circulating levels of interleukin‐17 and 25‐ hydroxycholecalciferol  in active acne vulgaris: Correlation to disease  severity
