Topical toluidine blue-mediated photodynamic therapy for the treatment of oral lichen planus.

Topical toluidine blue-mediated photodynamic therapy for the treatment of oral lichen planus. J Biol Regul Homeost Agents. 2019 May-Jun;33(3 Suppl. 1):27-33 Authors: DENTAL SUPPLEMENT, Romano A, Contaldo M, Della Vella F, Russo D, Lajolo C, Serpico R, Di Stasio D Abstract Photodynamic Therapy (PDT) is a minimally invasive approach that has shown promising results in management of oral, head and neck lesions. PDT can be used alone or in combination with other conventional treatments (surgery, chemotherapy, radiotherapy). Oral Lichen Planus (OLP) is a mucosal and cutaneous chronic disease characterized by an autoimmune insult of basal keratinocytes. We aim to evaluate the feasibility of topical toluidine blue-mediated PDT for the treatment of oral cavity multifocal homogeneous white lesions by oral lichen planus without dysplastic features.

Conclusion: PECAM-1 was found to be overexpressed in OLP; difference in PECAM-1 expression was noted between the reticular and erosive types. The VAMs could be exploited as a possible therapeutic target in OLP to modulate the disease process thereby reducing the dependency on corticosteroids.

CONCLUSIONS: This study on dry eye confirmed but also refuted many risk factors from smaller epidemiological studies, and discovered numerous new risk factors in multiple etiological categories. The finding that dry eye symptoms are particularly common in young adults is concerning, and warrants further study. PMID: 32376389 [PubMed - as supplied by publisher]

Authors: Chaitanya NC, Reshmapriyanka D, Pallavi K, Ameer S, Appala A, Chowdhary A, Prabhath T, Ratna MP, Sowmya BS, Vaishnavi C, Bontala P Abstract BACKGROUND: Oral lichen planus (OLP) is a T cell-mediated chronic autoimmune disorder directed against antigens secreted by the basal cell layer, with an incidence of 0.02-0.22% in Indian population and showing female predilection. Stress is considered one of the etiological factors in the causation, progression, and recurrence of this disease. OBJECTIVES: To evaluate the levels of serum cortisol, anxiety, and depression in patients with symptomatic OLP and to corr...

This study for the first time compares the expression of the aquaporin-3 (AQP3) gene in oral tissues of a group of OLP patients and a control group. In this study, 30 OLP patients and 30 healthy individuals were selected. The expression of AQP3 gene was measured using Real-Time PCR method. The expression of the gene in the OLP patients was more than the control group. It could be argued that decreased salivation increases the level of expression of the AQP3 gene in an effort to compensate for this deficiency and prevent the onset of xerostomia (compensatory up-regulation).

We report three patients who developed lichen sclerosus et atrophicus superimposed on skin involved by scleredema adultorum of Buschke. Although the association of lichen sclerosus et atrophicus with scleredema adultorum of Buschke could be coincidental, both diseases could be considered part of the spectrum of sclerodermoid disorders with common underlying pathogenetic mechanisms; which could explain the sequential or simultaneous occurrence of both lesions in our patients.

ConclusionsLeukocyte cell types and IL-17+ cells are important in this chronic disease process. This investigation adds to the scant body of literature on T-helper cell type 17 (Th17)/IL-17 involvement in canine idiopathic inflammatory and/or autoimmune diseases. As such, CCUS may represent a nonmouse model for other spontaneously occurring inflammatory diseases in canines and humans.

Many factors have been studied in order to identify the causes of oral lichen planus (OLP), such as use of drugs, autoimmune diseases, diabetes, and hepatitis C virus infection. Some researchers have been trying to find a connection between psychological states and OLP. The authors report a case of a 36-year-old female patient who went to the stomatology care service complaining of a "white ball on the tongue," which was causing her some discomfort over a year. During anamnesis, the patient reported taking lithium and bupropion (treating depression and anxiety, respectively).

Abstract BACKGROUND: microRNAs play a critical role in auto-immunity, cell proliferation, differentiation and cell death. miRNAs are present in all biological fluids, and their expression is essential in maintaining regular immune functions and preventing autoimmunity, whereas miRNA dysregulation may be associated with the pathogenesis of autoimmune and inflammatory diseases. Oral lichen planus (OLP) is an inflammatory disease mediated by cytotoxic T cells attack against epithelial cells. The present study aims to perform a specific microRNA expression profile through the analysis of saliva in this disease. M...
