Interleukin 9 in Oral Lichen Planus: an immunohistochemical study before and after treatment by intralesional steroid injection.

Oral Lichen Planus (OLP) is a chronic inflammatory mucocutaneous disorder of the oral mucosa. Th9 cells secrete IL9, which induces elevated levels of MMP9, exacerbating OLP disease severity. IL9 also increases Th17 levels in OLP lesions.

Clinicopathological evaluation of intralesional methotrexate in different subtypes of basal cell carcinoma.

Basal cell carcinoma (BCC) is the most common malignant skin tumor. While slowly growing, it can cause major skin disfigurement. Therefore, novel cosmetically acceptable treatment options, other than surgery require investigation.

Post COVID-19 Head and Neck Mucormycosis: MR Imaging Spectrum and Staging.

Objective: To develop a systematic approach for magnetic resonance imaging (MRI) analysis, imaging spectrum, and classification system for the staging of post-COVID-19 head and neck mucormycosis.

Method: The study included 63 post-COVID-19 patients with pathologically proven mucormycosis who underwent head and neck MR imaging. Three independent radiologists assessed the imaging spectrum of mucormycosis, MRI characteristics of sino-nasal mucormycosis, and extra-sinus extension, and submitted a final staging using a systematic approach and a proposed categorization system.

Squamous Cell Carcinoma Antigen in Psoriasis: An Immunohistochemical Study.

Background: Squamous cell carcinoma antigens (SCCA1, SCCA2) are members of the ovalbumin serpin family that have been described as biomarkers of squamous cell carcinomas. Different studies to date have stated the involvement of SCCA in the pathogenesis of certain immunological diseases, such as asthma and atopic dermatitis.

Objective: We sought to assess the expression of SCCA2 in the skin of patients with chronic plaque psoriasis and to detect its correlation with the clinical severity of psoriasis and with the density of inflammatory infiltrates in the skin lesions.

A combined approach of subcision with either cross-linked hyaluronic acid or threads in the treatment of atrophic acne scars.

Background: Acne scars are one of the most common cosmetic concerns causing psychosocial distress.

Objective: To evaluate the efficacy of subcision versus its combination with either cross-linked hyaluronic acid (HA) or poly-l-lactic acid (PLLA) threads in the treatment of atrophic post-acne scars.

Methods: Forty patients of both genders with atrophic acne scars were subjected to subcision 1 month apart for 3 sessions.

The Effect of Propolis in Healing Injured Nasal Mucosa: An Experimental Study.

Introduction: Mechanical trauma to the nasal mucosa increases the risk of synechia formation, especially after chronic rhinosinusitis and nasal surgeries.

Objective: This study was carried to assess the effect of propolis administration in healing injured nasal mucosa in rats.

Methods: We randomly divided eighteen rats into three equal experimental groups: (1) non-treated group; (2) gum tragacanth (suspending agent for propolis) treated group; and (3) propolis treated group.
