RESUMEN
Background: Psoriasis-specific proteins dysregulated in keratinocytes and involved in the pathophysiological process of psoriasis remains elusive.Objective: This study aimed to investigate the serum and tissue levels of Galectin3 in patients with psoriasis vulgaris before and after narrow-band ultraviolet B (NB-UVB) phototherapy.Methods: This study was designed as a cross-sectional case-control. This study included 30 patients with psoriasis Vulgaris and 20 healthy individuals. Psoriasis Area and Severity Index (PASI) score were used to evaluate the patients with psoriasis Vulgaris before and after treatment. All patients were treated two times per week for 3 months with NB-UVB phototherapy. Enzyme-linked immunosorbent assay (ELISA) was used to assess serum levels of galectin 3 of the healthy control subjects and psoriatic patients before and after treatment by NB-UVB phototherapy.Results: The serum level of galectin 3 was significantly lower in patients with psoriasis Vulgaris versus healthy control subjects (p value < .001). There was a significant increase in the serum levels of Galectin 3 and decrease in PASI scores after 3 months of treatment with NB-UVB phototherapy in patients with psoriasis Vulgaris (p value < .001).Conclusions: This study concluded that NB-UVB phototherapy for 3 months in patients with psoriasis Vulgaris was an essential method for decreasing PASI scores and an increase in the serum levels of galectin 3.

BACKGROUND AND OBJECTIVES: Striae are atrophic dermal scars with overlying epidermal atrophy causing cosmetic concern. This study assesses and compares the efficacy and safety of needling therapy versus CO2 fractional laser in treatment of striae. METHODS: Twenty Egyptian female patients with striae in the abdomen and lower limbs were involved in the study. The patients were treated with needling therapy and CO2 laser every 1 month for 3 sessions. Follow-up by digital photography and skin biopsy was conducted at baseline and 6 months after treatment. Clinical improvement was assessed by comparing photographs and patient's satisfaction before and after treatment. RESULTS: Nine of 10 (90%) needle-treated patients showed improvement. Among them, 3 (30%) had good, 4 (40%) had fair, and 2 (20%) had poor improvements; however, 1 (10%) did not show any improvement after the treatment. In CO2-laser treated patients, 5 of 10 (50%) of the patients showed clinical improvement; 1 (10%) were good, 3 (30%) were fair, and 1 (10%) were poor; however, 5 (50%) did not show improvement. CONCLUSION: The results support the use of microneedle therapy over CO2 lasers for striae treatment.
