OBJECTIVE: To explore the protective function of vitamin D (VD)/vitamin D receptor (VDR) on the development of oral lichen planus (OLP) and elaborate the underling mechanism of it. METHODS: H&E staining, myeloid Peroxidase (MPO) assays, quantitative PCR (qPCR), western blotting and Elisa were used to test the human biopsies and serum. QPCR, western blotting, Elisa and siRNA transfection were also performed in LPS-induced keratinocytes to observe the functions of vitamin D and VDR...

BACKGROUND: Oral lichen planus (OLP) is a chronic auto-inflammatory mucositis and potentially oral premalignant lesion. Erosive OLP patients display the higher canceration rate as compared to the patients with non-erosive OLP. Identification of the potential biomarkers associated with erosive OLP may help to investigate the disease pathogenesis and to improve clinical treatment. METHODS: Ultra-performance liquid chromatography-quadrupole time-of-flight-mass spectrometry (UPLC-QTOF-MS) combined with pattern recognition approaches were integrated to acquire differentially expressed metabolites for the pathways analysis and elucidate mechanisms of disease...

BACKGROUND: The oral examination is an essential part of the multidisciplinary medical care in elderly people. Oral mucosal lesions and normal variations of oral anatomy (OMLs) are very common in this people, but few studies have examined the frequency and prevalence of these conditions worldwide and less in Chile. The aim of this research was to evaluate the frequency of OMLs in a Chilean elderly population. MATERIAL AND METHODS: It was conducted a retrospective study (Talca, Chile)...

Lichen planus pigmentosus is a photodistributed dyschromia of unknown etiology described clinically as hyperpigmented gray-blue or brown-black macules or patches in a photodistributed pattern. Although there has been some debate, lichen planus pigmentosus is considered by many to be a separate diagnostic entity from ashy dermatosis or erythema dyschromicum perstans, which shares similar characteristics. Various treatment strategies have been applied to help resolve or improve the appearance of lichen planus pigmentosus lesions; however, an optimal treatment method is yet to be elucidated...

Vulvovaginal lichen planus is a type of chronic inflammatory dermatosis of the vulva, usually seen as a part of widespread lichen planus. The common clinical types of vulval lichen planus include papulosquamous, erosive and pigmented types. Hypertrophic lichen planus of the vulva is a rare entity. We report a case of hypertrophic lichen planus of the vulva which clinically simulated genital warts.

OBJECTIVE: To assess type C behavior in patients with oral lichen planus (OLP) in order to provide basis for clinical prevention, treatment and psychological intervention of OLP. METHODS: Type C behavior scale was used on 85 OLP patients and 85 control patients, who were in accordance with the inclusion criteria, in order to investigate their type C behavior. The scale included 9 items: anxiety, depression, anger, anger toward inside (anger-in), anger toward outside (anger-out), reasoning, domination, optimism, and social support...

OBJECTIVE: The bacterial community structure of buccal mucosa in patients with oral lichen planus was evaluated and compared with healthy control. SUBJECTS AND METHODS: Buccal scraping samples have been taken on 43 oral lichen planus patients (21 erosive and 22 non-erosive) and 21 mucosal healthy volunteers. The V3 hypervariable 16S rDNA region were amplified and sequenced by high-throughput 454 pyrosequencing. RESULTS: 94.26% of the total buccal bacteria were classified into 15 abundant genera...

PURPOSE: This study aimed to investigate the level of salivary endothelin-1 in premalignant and malignant lesions. MATERIALS AND METHODS: In this study, 75 cases were investigated of which 25 cases were healthy, 25 cases had oral lichen planus (OLP), and 25 cases had oral squamous cell carcinoma (OSCC). In order to collect the saliva samples, the unstimulated spitting was used. The samples were collected between 9 and 12 a.m. They were sent to the lab shortly after being collected and salivary endothelin-1 was recorded for each sample according to the instruction of factory by using enzyme-linked immunosorbent assay and optical density at a wavelength of 450 nm...

Reactive oxygen species (ROS) are involved in the pathogenesis of many inflammatory diseases, including oral lichen planus. Therefore, determining the salivary markers of oxidative stress is an excellent alternative approach to diagnosing oral cavity diseases. The objective of our study was to provide preliminary validation and determination of the salivary markers of oxidative stress in both patients with reticular and erosive forms of oral lichen planus as well as in healthy individuals without any oral lesions...

Chronic ulcerative stomatitis is an immune-mediated mucocutaneous disorder characterized clinically by erosions or ulcers. Most cases are limited to the mouth. The histopathological features are non-specific or mimic those of oral lichen planus, and studies by immunoflorescent microscopy are essential for definitive diagnosis. The defining immunopathogenic mechanism is the binding of IgG to the nuclear protein deltaNp63alpha of keratinocytes in the basal and parabasal cell layers of the oral stratified epithelium...

AIM: Type 2 diabetes mellitus (DM2) is a chronic disease caused by the underproduction of insulin in the organism and it is considered a risk factor to periodontal disease. MATERIALS AND METHODS: This study performed a cross-sectional research on the main oral changes in patients with DM2 and nondiabetics, in Passo Fundo, Rio Grande do Sul, Brazil. The sample included 116 patients examined at the Diabetes Outpatient Clinic of the School of Medicine of the University of Passo Fundo (UPF) and 134 nondiabetic patients examined at the Examinations, Triage, and Emergency Sector of the School of Dentistry of UPF...

OBJECTIVE: To carry out a double-blind RCT to compare the effectiveness of topical tacrolimus (TAC), triamcinolone acetonide (TRI) and placebo (PLA) in symptomatic OLP. SUBJECTS AND METHODS: A clinical score (CS, range 0-130) was developed to measure the clinical signs and symptoms of OLP. Twenty-seven OLP patients with a CS of ≥ 20 were randomly allocated to receive 0.1% TAC ointment (n=11), 0.1% TRI paste (n=7) or Orabase(®) paste as PLA (n=9) for 3 weeks. If the CS dropped ≥ 20% (interpreted as response), the patients continued the same medication for another 3 weeks...

BACKGROUND: B-cell activating factor (BAFF) belongs to the TNF superfamily of proteins, which influences the life span of normal and malignant cells. It has been demonstrated that there is an overexpression of BAFF in peripheral blood neutrophils and mononuclear cells in patients with oral squamous cell carcinoma (OSCC), suggesting a tumor-promoting activity of those cells. Taking into consideration that numerous OSCC cases are preceded by clinically evident oral potentially malignant disorders (OPMDs), involving e...

BACKGROUND: Chronic hepatitis C (CHC) infection causes a wide range of immune mediated hepatic and extrahepatic manifestations. Cutaneous manifestations constitute a major portion of the latter group. Host immune response to the virus - particularly regulatory T lymphocytes - is important in determining the outcome of the infection and the possibility of extrahepatic manifestations. The present study aims to investigate the relationship between immune-mediated cutaneous manifestations of CHC infection and the frequency of CD4+CD25 high FOXP3+ T regulatory lymphocytes...

In their recent publication, Garcia-Pola et al. (2016) suggested the development of proliferative verrucous leukoplakia (PVL) in oral lichen planus (OLP). It was described as a preliminary study, where this association supposedly occurred (1). They presented a retrospective analysis with a long-term follow-up, showing an interesting relationship between these lesions. It is important to emphasize that the clinical profile of patients with PVL is well recognized in the literature, mainly affecting non-smoking and non-drinking elderly women, older than 60 years (2-4)...
