[Precancers of the oral mucosa: clinic, diagnostics]. / Predraki slizistoi obolochki rta: klinika i diagnostika.

OBJECTIVE: The aim of the study. Improving the efficiency of diagnosis and detailing the features of the clinic of «potentially malignant¼ diseases of the oral mucosa. MATERIALS AND METHODS: Clinical and laboratory examination of 124 patients of the department of oral mucosa diseases aged 35 to 80 years, among whom there were 75 women and 49 men, with diseases such as erythroplakia - 12 patients, verrucous leukoplakia - 52 patients, erosive form of leukoplakia - 35 patients, cheilitis Manganotti - 25 patients. Histological and immunohistochemical methods of investigation were used as diagnostics. To assess the proliferative activity of epithelial cells, the determination of the Ki-67 index was used. The synthesis of keratin 15 (K15) in epithelial layers was determined as a diagnostic criterion for the severity of neoplasia. The expression of human papillomavirus type 16 (HPV 16) antigens and p16INK4a protein in epithelial cells was studied, as well as the expression of p53 protein. RESULTS: A high prevalence of p53 mutations was observed in patients with erythroplakia. In leukoplakia, the expression of the Ki-67 protein was detected in the cell nuclei in both the basal and parabasal layers of the multilayer squamous epithelium, in 77% of cases, the expression of the p16INK4a protein in the epithelial nuclei with varying degrees of dysplastic changes was noted, and a positive reaction to HPV16 was also observed in the cell nuclei and cytoplasm of epithelial cells in the basal, parabasal and spiny epithelial layers. The appearance of K15 in the cytoplasm of cells above the basal layer with abrasive precancerous cheilitis was found in 48% of cases. CONCLUSION: To diagnose early manifestations of neoplastic processes in «potentially malignant¼ diseases of the oral mucosa, it is necessary to use both classical histological and immunohistochemical methods of investigation with various markers.

Queilite angular em pacientes idosos: aspectos clínicos, microbiológicos, fatores etiológicos e manejo terapêutico / Angular cheilitis in elderly pacients: clinical and microbiological aspects, etiological factors and therapeutic management

Introdução: A queilite angular é uma lesão multifatorial de caráter essencialmente fúngico, que acomete as comissuras labiais e clinicamente se manifesta através de um padrão característico. Em idosos, em decorrência da idade avançada, o surgimento e a persistência da queilite angular ocorre em virtude da perda de dimensão vertical, edentulismo, imunossupressão, aumento da dobra cutânea, próteses mal adaptadas e redução da qualidade de vida. Objetivo: Realizar um levantamento na literatura científica acerca dos aspectos clínicos, microbiológicos, fatores etiológicos e tratamento da queilite angular em pacientes idosos. Métodos: Foram consultadas as bases de dados PubMed, SciELO e LILACS, utilizando os descritores DeCS/MeSH em português e inglês: "idosos", "queilite", "lesão", "elderly", "cheilitis" e "lesion". Após o cruzamento com o operador booleano AND, foi realizada apuração e análise, com a inclusão de 21 trabalhos. Para aprofundar a fundamentação teórica, 13 novas referências foram adicionadas, totalizando 34 estudos. Resultados: Clinicamente, a queilite angular se manifesta através de fissuras, eritemas, crostas uni/bilaterais, acompanhada de dor e prurido. A presença dos microrganismos Candida albicans, Staphylococcus aureus e Streptococcus pyogenes são comuns e dificultam no manejo terapêutico desta condição. Dentre as variadas formas de tratamento, destacam-se a Terapia Fotodinâmica antimicrobiana, uso de ácido hialurônico, além de antimicrobianos locais, especialmente os antifúngicos. Considerações finais: Por apresentar aspecto multifatorial e envolver diferentes tipos de microrganismos, seu manejo terapêutico é multimodal. Portanto, para um tratamento adequado, faz-se necessário que o cirurgião-dentista identifique as características clínicas e microbiológicas, além dos fatores etiológicos envolvidos no desenvolvimento da queilite angular.

Introduction: Angular cheilitis is a multifactorial lesion of essentially fungal character, which affects the labial commissures and clinically manifests itself through a characteristic pattern. In the elderly due to advanced age, the onset and persistence of angular cheilitis occurs due to loss of vertical dimension, edentulism, immunosuppression, increased skinfold, poorly adapted prostheses and reduced quality of life. Objective: To conduct a survey in the scientific literature about the clinical and microbiological aspects, etiological factors and treatment of angular cheilitis in elderly patients. Materials and methods: The PubMed, SciELO and LILACS databases were consulted, using the DeCS/MeSH descriptors in Portuguese and English: "idosos", "queilite" and "lesão"; "elderly", "cheilitis" and "lesion". After crossing with the Boolean operator AND, a survey and analysis was performed, with the inclusion of 21 studies. To deepen the theoretical foundation, 13 new references were added, totaling 34 studies. Results: Clinically, angular cheilitis manifests itself through fissures, erythemas, unilateral or bilateral crusts, accompanied by pain and itching. The presence of the microorganisms Candida albicans, Staphylococcus aureus and Streptococcus pyogenes are common and hinder the therapeutic management of this condition. Among the various forms of treatment, we highlight the antimicrobial Photodynamic Therapy, use of hyaluronic acid, as well as local antimicrobials, especially antifungals. Final considerations: Because it presents a multifactorial aspect and involves different types of microorganisms, its therapeutic management is multimodal. Therefore, for an adequate treatment, it is necessary for the dentist to identify the clinical and microbiological characteristics, in addition to the etiological factors involved in the development of angular cheilitis.

Cheilitis: A Diagnostic Algorithm and Review of Underlying Etiologies.

Cheilitis, or inflammation of the lips, is a common reason for dermatologic consultation. The inflammation can include the vermillion lip, vermillion border, and surrounding skin, and can present with an acute or chronic course. There are many etiologies, including irritant and allergic contact dermatitis, atopic cheilitis, actinic cheilitis, infectious etiologies, nutritional deficiencies, drug-induced cheilitis, and rare etiologies, including granulomatous cheilitis, cheilitis glandularis, plasma cell cheilitis, lupus cheilitis, and exfoliative cheilitis. Distinguishing among the various etiologies of cheilitis is clinically difficult, as many causes may produce similar erythema and superficial desquamation of mucosal skin. In addition, patients report dryness, redness, irritation, burning, fissuring, and itch in many of the underlying causes. Thus, the specific etiology of cheilitis is often difficult to diagnose, requiring extensive testing and treatment trials. In this review, we summarize the various types of cheilitis, synthesizing novel cases, clinical presentations, histopathology, epidemiology, and advancements in diagnostic methods and therapeutics. We provide a diagnostic algorithm aimed to assist clinicians in the management of cheilitis.

Histopathologic findings in ointment pseudo-cheilitis: An alert to dermatopathologists.

Ointment pseudo-cheilitis is a recently recognized distinctive type of self-induced cheilitis. Lesions consist of a variable amount of crusts adhered to the vermilion. These crusts consist of dried saliva and dead cells mixed with applied medications attached to the lip surface. Patients are typically severely anxious or depressed; the condition impacts quality of life. Ointment pseudo-cheilitis is frequently misdiagnosed as exfoliative cheilitis or cheilitis glandularis. Biopsy reports are often non-revealing because there are no established histopathological criteria for this disease, and clinicians usually do not formulate the correct diagnostic hypothesis. Here, we present the histopathological findings of four cases of ointment pseudo-cheilitis. The most consistent finding was the presence of laminated parakeratotic material detached from the epithelium in biopsies that are devoid of other significant diagnostic changes. This material at the lip surface possibly represents physiologic labial desquamation mixed with dried saliva and applied medication. With this report, we intend to alert dermatopathologists to the diagnosis of ointment pseudo-cheilitis if they receive biopsies from patients who present clinically exuberant labial lesions that show only minimal histopathological changes.

Multiple noninvasive auxiliary tests-assisted photodynamic therapy in actinic cheilitis: A case report.

Actinic cheilitis (AC) is recognized as the most common precursor lesion of squamous cell carcinoma (SCC) of the lip, with a higher risk of invasiveness and metastasis. Early accurate diagnosis and appropriate therapy are essential to prevent carcinogenesis and progression of AC. Topical 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT), a non-surgical and minimally invasive modality, has been proposed as an effective treatment for oral potentially malignant diseases (OPMDs) and oral cancers. Herein, we report a 64-year-old female patient with AC on the lower lip who received 3 sessions of ALA-PDT with an interval of 1 week. Multiple noninvasive auxiliary tests including autofluorescence imaging, toluidine blue staining, and aneuploidy with DNA image cytometry (DNA-ICM) using brushing from screening through diagnosis, treatment, and follow-up. The patient successfully showed a complete response with no adverse effects and no evidence of recurrence at the 20-month follow-up. Noninvasive auxiliary tests assisted PDT is attractive and well-tolerated and may have synergistic effects against AC.

Laminin Immunostaining in Biopsies as a Useful Biomarker of Early Invasion in Actinic Cheilitis and Differential Diagnosis Between Actinic Cheilitis and Lip Cancer: New Insights.

BACKGROUND: Squamous cell carcinoma of the lip (LSCC) and oral cavity can be life-threatening if not diagnosed early. Precancerous lesions like actinic cheilitis (AC), can transform into LSCC. Laminin is a fundamental component for basement membrane (BM) and its integrity may prevent neoplastic invasion. Therefore, laminin immunostaining of BM may be useful in identifying early invasion in actinic cheilitis and thus in the differential diagnosis between AC and invasive LSCC or high-grade epithelial dysplasia (ED). MATERIALS AND METHODS: Biopsies from 46 patients with oral lesions were histologically analyzed and immunohistochemically stained for laminin-1. RESULTS: AC was diagnosed in 34 patients and LSCC in 12 patients, including 3 patients with AC and concomitant high-grade ED/in situ carcinoma. Laminin-1 immunostaining revealed intense and linear expression of the BM in AC with low-grade ED. Loss of laminin expression was observed in LSCC. Intracellular laminin expression in parabasal cells was noted in AC with high-grade ED/in situ carcinoma. CONCLUSION: Laminin immunostaining could be useful in identifying AC cases suspected of early invasion. It could also contribute to the histopathological differential diagnosis between AC with low- and high-grade ED and between AC and invasive LSCC. The findings of this study provide new insights into the mechanism involved in the progression process of AC into LSCC, encouraging preclinical studies that may document the stochastic role of laminin in this process.

Actinic cheilitis in rural workers: prevalence and associated factors.

OBJECTIVE: To evaluate the prevalence of actinic cheilitis in rural workers and factors associated with the development of this condition. METHODS: A cross-sectional study was conducted in a city in Northeastern Brazil. Data were collected by clinical examination and use of a questionnaire validated with 300 rural workers. The χ2 test was employed to identify possible associations between the presence of actinic cheilitis and clinical and demographic variables. Multiple logistic regression analysis was performed using forward stepwise selection. A p value of 0.05 was considered significant. RESULTS: The prevalence of actinic cheilitis was 12.0% in the sample. The highest prevalence of actinic cheilitis was observed in white males, with low educational level, and an approximately 40-year history of sun exposure. Chronic lesions were commonly found in the lower lip and were characterized by scaling, dryness, and mild edema. Skin color, sex, educational level of patients, and cumulative sun exposure (in years), were identified as predictors of development of actinic cheilitis. CONCLUSION: Our results suggest the need to implement educational health strategies aimed to orient the population about risk factors and preventive measures of the disease. Appropriate clinical management of patients with actinic cheilitis is important for prevention of lip cancer.

Actinic cheilitis: Proposal of a clinical index.

BACKGROUND: Actinic cheilitis is a potentially malignant lesion most commonly found in the lower lip of individuals with chronic exposure to ultraviolet radiation. The aim of this study was to develop and to test a clinical index that can be used to assess the severity of actinic cheilitis. MATERIAL AND METHODS: The clinical index of actinic cheilitis was applied to 36 patients. An incisional biopsy was obtained to grade oral epithelial dysplasias following the World Health Organization (WHO) and binary systems, and to evaluate their association with clinical characteristics by Fisher's exact test (P<0.05). The accuracy of the index was evaluated based on sensitivity, specificity, positive and negative predictive values, and receiver operating curve. RESULTS: The blurring between the border of the lip and the skin was significantly associated with cases without dysplasia/mild epithelial dysplasia (P=0.041) and with low risk of malignancy (P=0.005). Ulcers and crusts were significantly associated with moderate/severe epithelial dysplasia (P=0.002 and P=0.012, respectively) and high risk of malignancy (P=0.005 and P=0.045, respectively). Erosion showed a significant association only with high-risk cases of malignancy (P=0.024). The cut-off values of the diagnostic test showing the best performance were 10 for the WHO grading system and 11 for the binary system. CONCLUSIONS: The index cut-offs with the highest accuracy were considered indicators for a biopsy. Erosion, ulceration and crusts were associated with more severe oral epithelial dysplasias.

First isolation and identification of Cystobasidium calyptogenae from the oral samples of an elderly patient presenting with angular cheilitis.

BACKGROUND: Angular cheilitis, an infection mainly caused by Candida yeasts, is featured by the appearance of inflammatory lesions at the bilateral corners of the mouth, particularly in patients with poor oral hygiene, ill-fitting dentures and old age. The first isolation of an atypical yeast, Cystobasidium calyptogenae, from oral samples of a patient presenting with angular cheilitis is discussed in this study. CASE PRESENTATION: Angular cheilitis was diagnosed in a 60-year-old denture-wearing woman who presented with an irritation fibroma on her right lower buccal sulcus over the premolar region. Primary cultures of her oral swab and oral rinse samples grew a pure culture of an uncommon yeast strain resembling Rhodotorula sp. Sequence analysis of the yeast internal transcribed spacer (ITS) gene region and D1D2 domain showed highest similarity (99.6% and 100%, respectively) to C. calyptogenae CBS 9125 type strain. Following 2 weeks of treatment with miconazole/fusidic acid and mouthwash, the oral lesion showed improvement with less erythema. C. calyptogenae was not isolated from the patient's oral samples upon repeat sampling. CONCLUSION: This is the first report on the isolation of C. calyptogenae from human oral samples. The ability of C. calyptogenae to grow at 37 °C and the fact that it was the only yeast species isolated from the patient's oral samples suggests its pathogenic potential and possible involvement in angular cheilitis. The ubiquitous nature of the Cystobasidium yeast is believed to increase the likelihood of opportunistic infections among immunocompromised individuals. As Cystobasidium is phenotypically indistinguishable from Rhodotorula, an emerging opportunistic pathogen, surveillance using molecular identification in clinical settings is essential in providing accurate diagnosis and treatment of uncommon yeast infections.

Immunohistochemical comparative analysis of IMP-3 and KI-67 in actinic cheilitis and lower lip squamous cell carcinoma.

Actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC) exhibit epithelial alterations mainly associated with chronic ultraviolet ray exposure. Currently, it is impossible to predict which AC cases will progress to LLSCC; thus, biomolecular markers have been studied. The aim of this study was to evaluate the immunoexpression of IMP-3 and KI-67 in AC and LLSCC. Forty AC and 40 LLSCC cases were submitted to peroxidase method and quantitatively analyzed, using the following scores: 0 (0% positive cells), + 1(≤ 30%), + 2 (> 30% to ≤ 60%), and + 3 (> 60%). Results were submitted to non-parametric Mann-Whitney (U) test. A p value < 0.05 was considered to indicate statistical significance. IMP-3 immunoexpression was observed in 26 AC cases, with predominance of the score 1 (35% of cases). This protein was also positive in 22 LLSCC cases, with predominance of the score 3 (37.5% of cases). Immunoexpression of KI-67 was observed in all studied cases, with predominance of the score 2 (70% of AC cases and 57.5% LLSCC cases). The association between IMP-3 and Ki-67 immunoexpression, AC dysplastic severity and LLSCC tumoral grade revealed no significant differences. The present results demonstrate that IMP-3 and Ki-67 immunoexpression are frequent in AC and in LLSCC. Moreover, these proteins could be involved in lower lip carcinogenesis process.

Allergic contact cheilitis caused by propolis: case report

ABSTRACT Propolis is a lipophilic resin extracted from plants by bees. The purpose of this case report was to show the importance of this substance as cause of allergic contact cheilitis. A 21-year-old female patient complained of pruritic perioral eczema for 5 years. In the past months it also affected the neck. After diagnosing contact dermatitis, she was submitted to a patch test with a Latin American baseline series. The result was strongly positive for propolis (++) and weakly positive for perfume mix I (+). After the test, the patient revealed she had been using propolis drops, per oris, for 10 years. The worsening of the condition was due to increased dose, aiming "to improve immunity", during the coronavirus disease 2019 (COVID-19) pandemic. The contact allergy to propolis might be increasing due to the widespread use of natural products. Propolis is a sensitizer to be considered in patients with long-lasting cheilitis.

A Severe Presentation of Plasma Cell Cheilitis.

Plasma cell cheilitis (PCC) is an uncommon condition characterized by mature plasma cell infiltration of the dermis of the mucosal lip. The condition often presents as a red-brown patch or plaque on the lower lip in older individuals that can progress to erosions and edema. Diagnosis can be delayed because clinical findings are nonspecific and can mimic neoplastic, infectious, and inflammatory conditions. We describe a patient with PCC who presented to our institution via teledermatology. Findings were equivocal on 2 early biopsies until the presentation evolved to dramatic ulceration and necrosis, which prompted a third biopsy that was diagnostic for PCC. Empiric therapy with a class I topical corticosteroid was successful.

Introduction: Actinic cheilitis is an inflammatory, potentially malignant lesion associated with excessive sun exposure. Objective: To evaluate the prevalence of actinic cheilitis in a group of farmers, as well as the perception and knowledge of that group about this lesion. Methods: The observational epidemiological study included Brazilian semi-arid region farmers. The sample was obtained for accessibility to this population and a total of 219 farmers was reached. A structured questionnaire was used to collect the data in addition to the intraoral physical examination. Results: Actinic cheilitis was diagnosed in 30.6 percent of the examined farmers. The lesion was found more frequently in males (86.6 percent), older than 60 years (64.2 percent), and leukoderma (58.2 percent). Most individuals with actinic cheilitis were exposed to solar radiation for more than 30 years (65.7 percent), for more than 6 hours a day (73.1 percent), and did not adequately protect themselves (94 percent). Sex, age, education level, drinking habits, and time of sun exposure had a statistically significant correlation with the presence of actinic cheilitis (p < 0.05). It was found that 76.1 percent of the participants did not notice signs and 61.2 percent did not perceive symptoms of this injury. Knowledge about actinic cheilitis was low for 97 percent of individuals with the lesion. Conclusions: The results showed a high prevalence of actinic cheilitis, in addition to low perception and knowledge about it, which indicates the need for health education actions(AU)

Association between cheilitis granulomatosa and odontogenic infections: A case-control study.

The association between cheilitis granulomatosa and dental infections (dental caries and apical periodontitis) is still not well understood. Herein, we aimed to investigate the association in large hospital cases with cohort controls. Cheilitis granulomatosa cases (n = 181) were retrieved from Peking University Hospital of Stomatology and age- and sex-matched to controls (n = 181). The χ2 -test, Student's t-test, and Mann-Whitney U-test were used to compare the differences between groups. The χ2 -test and odds ratio were used to verify if there was an association and risk relationship. The results showed that both dental caries and apical periodontitis were associated with cheilitis granulomatosa (p < 0.001). Individuals with cheilitis granulomatosa had approximately a twofold increased frequency of dental caries than those without cheilitis granulomatosa (104/181, 57.5% vs. 53/181, 29.3%) (p < 0.001). The odds ratio of dental caries occurring in the case group compared to the control group was 3.211. The frequency of apical periodontitis in patients with cheilitis granulomatosa was significantly greater than in those without cheilitis granulomatosa (109/181, 60.2% vs. 28/181, 15.5%) (p < 0.001). The odds ratio was 8.272. Moreover, apical periodontitis was also locationally related to cheilitis granulomatosa (p < 0.001). Collectively, our study showed that the foci of dental infections are associated with cheilitis granulomatosa, suggesting that proper treatment of focal teeth may be important in the management of cheilitis granulomatosa.

Assembling a consensus on actinic cheilitis: A Delphi study.

AIMS: To discuss the terminology to define and classify actinic cheilitis (AC) and to build a consensus on the diagnostic and therapeutic approaches to AC. METHODS: Two-round Delphi study using a questionnaire including 34 closed sentences (9 on terminology and taxonomy, 5 on potential for malignant transformation, 12 on diagnostic aspects, 8 on treatment) and 8 open questions. Experts' agreement was rated using a Likert scale (1-7). RESULTS: A consensus was reached on 24 out 34 statements (73.5%) and on 5 out of 8 (62.5%) close-ended questions. The response rate was identical in both rounds (attrition of 0%). AC is the term with the highest agreement (median of 7 (strongly agree; IQR: 6-7)) and the lowest dispersion (VC = 21.33). 'Potentially malignant disorder' was the preferred classification group for AC (median of 7) and 85.6% of participants showing some level of agreement (CV < 50). Experts (66.75%) consider AC a clinical term (median: 7; IQR: 4-7) and believe definitive diagnosis can be made clinically (median: 6; IQR: 5-7), particularly by inspection and palpation (median: 5; IQR: 4-6). Histopathological confirmation is mandatory for the management of AC (median: 5; IQR: 2.5-7), even for homogeneous lesions (median: 5; IQR: 3.5-6). Consensus was reached on all treatment statements (VC < 50). CONCLUSIONS: AC is a potentially malignant disorder with a significant lack of agreement on diagnostic criteria, procedures, biopsy indications and the importance of techniques to assist in biopsy. A consensus was reached on nomenclature and management of this disorder.

Comparison of Interventional Methods to Motivate and Change the Behavioural Stage of Smokers to Quit Smoking- A Hospital Based Randomised Controlled Trial.

OBJECTIVE: Addictions can be beaten if started off with a true motivation to quit it. Enhancing motivation is an important part of overall treatment for smoking cessation as it increases a smoker's courage and enthusiasm to quit smoke. This study aimed to assess effectiveness of various interventional methods to motivate unmotivated smokers with a focus on changing behavioural stage of  smokers to quit. METHODOLOGY: A single blinded trial was conducted at the outpatient department of ITS dental college and hospital among precontemplation stage smokers allocated into 4 groups and given interventional therapies like general counselling only(group 1), counselling and intra oral camera assessment (Group 2), counselling as well as carbon monoxide monitoring(Group 3)whereas fourth group(Group 4) given a combination therapy of all of them. A baseline evaluation of nicotine dependence and behavioural stage of the smoker was assessed. The patients were then evaluated on presence on their scheduled follow up visits done at interval of 2 weeks and 4 weeks. Descriptive statistics were addressed and the association was evaluated using Pearson chi square test. Any p value less than 0.05 was considered statistically significant. RESULTS: Majority of  smokers were males(88% ) and about 48.8% of them were highly dependent smokers . The change in precontemplation behavioural stage was assessed on basis of follow up visits after interventional therapy which was significantly higher in group 4 receiving combination therapy, followed by carbon monoxide therapy ,counselling and intra oral camera assessment and the least visits in behaviour counselling group (p <0.05). CONCLUSION: A combination of counselling and other motivational aids therapy is best way possible to help smokers focusing a change on the behavioural stage of the patient from precontemplation to preparation stage.

Successful Treatment of Periorificial Dermatitis With Novel Narrow Spectrum Sarecycline.

Broad spectrum tetracyclines are a well-known, widely used, and often successful treatment for use in inflammatory skin pathologies such as acne and rosacea. However, the steady rise of antibiotic resistance and gut dysbiosis associated with broad spectrum tetracyclines emphasizes the importance and responsibility of antibiotic stewardship. Narrow spectrum antibiotics have become increasingly important therapies to slow the progression of resistance as well as decrease negative side effect profiles, particularly those associated with broad spectrum tetracyclines. This case shows the successful treatment of periorificial dermatitis with a novel, narrow spectrum tetracycline, sarecycline, in a patient with underlying Crohn’s.
