Probiotics and Prebiotics Orally Assumed as Disease Modifiers for Stable Mild Atopic Dermatitis: An Italian Real-Life, Multicenter, Retrospective, Observational Study.

The role of the skin-gut axis in atopic dermatitis (AD) remains a subject of debate, limiting non-pharmacological interventions such as probiotics and prebiotics. To improve understanding of their potential as a monotherapy for stable mild cases, we conducted a real-life, multicenter, retrospective observational study in Italy. We administered three selected bacteria (Bifidobacterium animalis subsp. lactis BS01, Lactiplantibacillus plantarum LP14, and Lacticaseibacillus rhamnosus LR05) orally to patients with mild atopic dermatitis without a placebo control group, following up for 12 weeks. Clinical assessments using the Scoring Atopic Dermatitis (SCORAD), Eczema Area and Severity Index (EASI), and Three-Item Severity (TIS) score were conducted on 144 enrolled patients (average age: 25.1 ± 17.6 years). Notably, both pruritus and AD-related lesions (erythema, edema/papules, excoriation) exhibited significant clinical and statistical improvement (p < 0.001) after 12 weeks of exclusive probiotic and prebiotic use. These preliminary results suggest a potential link between the skin-gut microbiome and support the rationale for using specific probiotics and prebiotics in mild AD, even for maintenance, to reduce flares and dysbiosis.

Amelanotic vulvar melanoma: a case report.

A 14-year-old girl stated that she has vulvar pruritus, pain, and bleeding and underwent a complete gynecological evaluation during which a suspicious 2-cm achromic lesion on her vulva was observed. Initially, it was suspected to be a pyogenic granuloma, in relation to the patient's age. A biopsy was taken, and a histopathological diagnosis of amelanotic mucosal melanoma was made. Pyogenic granuloma is a reactive hyperproliferation vascular response to trauma or other stimuli. It predominantly occurs in the second decade of life in young females, in relation to the vascular effects of female hormones. Primary mucosal melanoma is a rare and aggressive neoplasm, characterized by a higher aggressiveness and a worse prognosis than her cutaneous counterpart. The female genital tract is the second most common site of onset of mucosal melanoma; it represents the 3% of melanomas diagnosed in women.
