Introduction. Oral lichen planus (OLP) is an autoim- mune disease of unknown etiology, manifested in vari- ous clinical forms. A correlation between intensity of OLP local manifestations and severity of general disturbances predisposing to altered oral mucosa have been poorly investigated. The aim of our study was to identify criteria for assessing OLP severity score. Methods. OLP patients and control subjects (not OLP) matched by hepatobiliary disease and type IIa dyslipidemia were examined. Samples collected during the study were as- sessed by way clinical examination, gas chromatographic analysis of serum free fatty acids (FFA), oral fluid, serum and fecal microbial marker analysis by gas chromatogra- phy/mass spectrometry, laser Doppler flowmetry of the oral mucosa, immunohistochemistry staining with an- ti-CD68 monoclonal antibody specific to apolipoprotein B-100-bearing macrophages. Results. It was found that OLP patients significantly differed from control subjects in the three FFA levels (lauric acid, eicosopentaenoic/ lauric and eicosopentaenoic/linoleic ratios), displayed four pathologic factors matching the altered level of mi- crobial markers. In addition, OLP patients were found to differ in oral mucosa blood filling both inside and outside lesions paralleled with oxidative changes immediately in oral mucosa highlighted as elevated amount of apo- lipoprotein B-100-bearing CD68-positive macrophages. Conclusion. OLP severity score is an integrate parameter which reflects oxidative changes and alterations in oral mucosa microhemocirculation primarily in serum free fat- ty acid composition, altered oral and gut microbiota as well as intensity score of clinical picture.

The aim of this case report is to present a histologically diagnosed oral lichen planus excised by the CO2 laser. Oral lichen planus is a chronic inflammatory mucocutaneous disease of unknown etiology. Different treatments have been used to manage this condition. A 46 year-old female was referred to the Laser Clinic of the Dental School of the Federal University of Bahia to excise a lesion characterized by white patches on the oral mucosa, which was causing pain and burning sensation and had not respond to treatment with triamcinolone and corticosteroids for 3 months. CO2 laser was used to remove the lesion and the conclusive histopathological diagnosis was oral lichen planus. The patient was followed up over 1year with no signs of lesion recurrence. The use of the CO2 laser was found to be useful and effective to treat lichen planus.

The objective of this study was to evaluate the cellular proliferative potential of oral lichen planus (OLP) lesions from patients without hepatitis C virus (HCV) by means of AgNOR method, as well as the cellular proliferative potential of the normal oral mucosa from patients with HCV, treated or untreated by interferon and ribavirin. A cross-sectional study was developed to investigate four groups: 10 HCV+ patients without clinical signs of OLP who had never been treated for HCV infection - Group 1; 10 HCV+ patients that were under interferon and ribavirin treatment - Group 2; 15 patients with reticular OLP lesions histopathologically confirmed, without HCV - Group 3; and 15 blood donors without HCV infection and no clinical signs of OLP GROUP 4 Control Group. The cytological material of all groups was collected by the liquid-based cytology technique. Then, the sedimented material from each patient was filled with the Nucleolar Organizer Regions impregnation by silver method (AgNOR). The count of NORs was performed on 100 epithelial cell nuclei per patient using the Image Tool(tm) software. The Tukey HSD test was used to compare the median value of NORs among the groups and showed that the oral mucosa of HCV+ patients previously treated with anti-HCV drugs (GROUP 2), presented a higher average number of NORs in relation to others (p<0.05). The anti-HCV treatment may be related to increased cell proliferation of oral mucosa, indicating a possible relationship between OLP and HCV+ patients treated with interferon and ribavirin.

Oral lichen planus (OLP) is a chronic inflammatory disease with different clinical types. Reticular and erosive forms are the most common. Although the cause of OLP remains speculative, many findings suggest auto-immune involvement, mediated by T lymphocytes against the basal keratinocytes. Inflammation, mechanical trauma or toxic agents can affect the epithelial homeostasia. Increased apoptosis may cause a decrease in epithelial thickness reflecting in the activity of the lesion. The objective of this study was to evaluate the occurrence of apoptosis and epithelial thickness in reticular and erosive forms of OLP. 15 samples of OLP each type (reticular and erosive) plus 10 of healthy mucosa were collected and processed. After morphometry, the apoptotic index and epitelial thickness were obtained. TUNEL and M30 CytoDEATH immunohistochemical assay were used to validate the morphologic criteria used. Apoptosis in the erosive OLP was significantly more intense than in the reticular type and both forms of OLP presented more apoptosis than the healthy oral mucosa. Healthy oral mucosa was thicker than both OLP forms and thicker in OLP reticular form than in the erosive one. The clinical differences between reticular and erosive forms of OLP are related to variations in epithelial thickness and in intensity of apoptosis.

Abstract Background Oral lichen planus (OLP) is a chronic mucocutaneous disease characterized by adult predominance and a prolonged course. However, it is rare in the pediatric population with familial aggregation. Case presentation A 3-year-old boy presented with pain and irritation on the oral mucosa while contacting spicy food for 2 months. Oral examination showed widespread whitish reticular and papular lesions on the lips, the dorsum of the tongue, and bilateral buccal mucosa, with diffuse erosions covered with pseudomembrane on the buccal mucosa. The boy’s parents were examined to exhibit white reticular and plaque-like lesions on their oral mucosa. The three patients were clinically diagnosed as affected by OLP and histopathologically confirmed. The boy underwent topical treatment with recombinant bovine basic fibroblast growth factor (rb-bFGF) gel, and oral lesions gradually resolved and healed. Neither of his parents received treatment. During the subsequent follow-ups, none of three patients underwent any medical treatment. Fortunately, their lesions had almost faded over 8 years. Conclusions Our case emphasizes that pediatric OLP should be recorded with family history. Besides, long-term periodic follow-up is recommended in pediatric patients with OLP for monitoring any changes in lesions.

Interleukin- (IL-) 23/IL-17 axis is a newly discovered proinflammatory signaling pathway and has been implicated in the pathogenesis of many chronic inflammatory and immune disorders. Here we investigated whether the IL-23/IL-17 axis was present and functional in the lesions of oral lichen planus (OLP), a chronic inflammatory disease affecting the oral mucosa. Using immunohistochemistry and quantitative PCR, we found that the subunits of IL-23 and IL-17 were overexpressed in OLP lesions than in normal oral mucosa tissues. In addition, the expressions of IL-23 and IL-17 are positively correlated in reticular OLP tissues. Results from in vitro studies revealed that exogenous IL-23 could increase the percentage of Th17 cells and IL-17 production in the CD4+T cells from reticular OLP patients. Furthermore, we also found that exogenous IL-17 could significantly enhance the mRNA expressions ofβ-defensin-2, -3, CCL-20, IL-8, and TNF-α, but notβ-defensin-1, CXCL-9, -10, -11, CCL-5, and IL-6 in human oral keratinocytes. Taken together, our results revealed an overexpression pattern and selectively regulatory roles of IL-23/IL-17 axis in the OLP lesions, suggesting that it may be a pivotal regulatory pathway in the complex immune network of OLP lesions.

Prevalence and severity of generalized parodontitis depend especially on the course of diseases affecting theoral mucosa and those ones which are characterized by involvement of the oral mucosa. These diseases include mainly lichen planus. The common pathogenic agent of generalized parodontitis and lichen planus as well as of combination of them is inflammation, as generalized parodontitis is inflammation of parardontium tissue characterized by destruction of periodontium and dental ligamentous apparatus of the alveolar bone and lichen planus is a chronic inflammatory disease of skin and oral mucosa. The purpose is to study processes of lipid peroxidation in the saliva of patients with lichen planus of the skin along with chronic generalized parodontitis.

Background: Lichen Planus is a common mucocutaneous disease with unknown etiology. Immunodeficiency is a known predisposing factor to this disease. Oral Candidiasis which is an opportunistic fungal infection, commonly affects healthy and immune-compromised patients. Candida has different species bearing different treatments. In this study, researchers aimed to detect the frequency and colonization rate of Candida and its association with different factors such as lesion types of oral lichen Planus (OLP).Materials and Methods: Thirty seven untreated oral lichen Planus patients, attending the Clinical Department of Oral Medicine at Shiraz Dental School in 2011, were selected. Swab method and CHROMagar media were used to obtain samples incubated for 48 hours at 30 ºC. Fungal species were detected considering colony color changes.Results: In the culture test, approximately 80% of samples were positive of non-reticular type. About 40% of positive samples were of Candida non-albicans (C.Non-albicans) type. Among C. Non-albicans, 85% were non-reticular type among OLP patients. There was no significant statistical difference in prevalence of Candida albicans (C.albicans) and C. Non-albicans in OLP patients.Conclusion: Based on results, certain biotypes of Candida were not confirmed responsible for OLP patterns.[GMJ.2014;3(4):252-5]
