Oral cancer and oral potentially malignant disorders in patients with Fanconi anemia - A systematic review.

The purpose of the present study was to perform a systematic review focusing on oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMD) in Fanconi anemia (FA) individuals. Electronic searches were undertaken in five databases supplemented by manual scrutiny and gray literature. Case reports and/or cases series were included. The searches yielded 55 studies describing 112 cases of OSCC (n = 107) and/or OPMD (n = 5) in FA individuals. The mean age at diagnosis of OSCC/OPMD was 27.1 (±9.6) years, and females (51.8 %) were slightly more affected. Ulcer (n = 37) or mass (n = 25) were described as clinical presentations for OSCC and OPMD. White lesions (n = 4) were the most common manifestation in OPMD. Tongue (47.2 %) was the most frequent location. Sixty-one (54.5 %) individuals underwent HSCT. Surgical resection (n = 75) was the main treatment adopted. The estimated rate of OPMD malignant transformation was 1.8 % and recurrences following OSCC excision occurred in 26.8 % of individuals. Overall, at 60 months of follow-up, the probability of survival fell to 25.5 % and at 64 months the probability of recurrence increased to 63.2 %. The present data support the need for strict surveillance of patients with FA, even in the absence of OPMD, for early OSCC detection and reduction of mortality.

Profiling salivary miRNA expression levels in Fanconi anemia patients - a pilot study.

The overarching goal of this study is to predict the risk of developing oral squamous cell carcinoma (OSCC) in Fanconi anemia (FA) patients. We have compared the microRNA (miRNA, miR) expression levels in saliva samples from FA patients (n = 50) who are at a low-moderate and/or high risk of developing OSCC to saliva samples from healthy controls (n = 16). The miRNA expression levels in saliva samples were quantified using qPCR. We observed that miR-744, miR-150-5P, and miR-146B-5P had the best discriminatory capacity between FA patients and controls, with an area under the curve (AUC) of 94.0%, 92.9% and 85.3%, respectively. Our data suggest that miR-1, miR-146B-5P, miR-150-5P, miR-155-5P, and miR-744 could be used as panel to predict the risk of developing OSCC in FA patients, with a 89.3% sensitivity and a 68.2% specificity (AUC = 81.5%). Our preliminary data support the notion that the expression levels of salivary miRNAs have the potential to predict the risk of developing OSCC in FA patients and in the future may reduce deaths associated with OSCC.

Cancer in buccal mucosa in patients with Fanconi anemia: Report of six cases.

INTRODUCTION: Fanconi anemia (FA) is a recessive hereditary disease characterized by bone marrow failure, and the treatment is hematopoietic stem cell transplantation (HSCT). Patients diagnosed with FA are more predisposed to develop oral squamous cell carcinoma (SCC), and this risk increases in transplant patients. The clinical characteristics of the oral manifestations of SCC in this group of patients do not differ from the lesions present in patients without the disease; however, they can be diagnosed in young patients and less common locations, such as, for example, in the buccal mucosa. OBJECTIVE: To report a case series of patients diagnosed with FA with oral SCC. METHOD: Included in this case series are six patients diagnosed with SCC in the buccal mucosa with similar clinical characteristics. FINAL CONSIDERATIONS: There are still difficulties in establishing the natural history of oral lesions in patients with FA. Thus, disclosing a series of cases with similar changes may be relevant to improving and refining the multidisciplinary team's clinical view of suspected SCC or oral potentially malignant disorders (OPMD), providing surveillance and timely management.

Atenção à saúde bucal de pacientes com coagulopatias hereditárias / Atención de salud bucal parapacientes con coagulopatías hereditarias: la contribución de los estudiantes a la reestructuración de la atención / Oral health care for patients with hereditary coagulopathies: the students' contribution to the re-structuring of health care

Por apresentarem maior risco de sangramento durante a realização de procedimentos odontológicos, pacientes diagnosticados com coagulopatias ou trombopatias hereditárias apresentam, frequentemente, dificuldade de acesso à assistência odontológica na Atenção Primária em Saúde. Alguns centros especializados no tratamento dessas doenças contam com o cirurgião-dentista como parte da equipe multiprofissional, permitindo que a maioria dos pacientes realizem o acompanhamento odontológico em tais serviços. Este estudo tem como objetivo relatar a experiência dos discentes de graduação e pós-graduação em Odontologia da Universidade Federal do Paraná na reabertura do ambulatório odontológico de assistência à pacientes com coagulopatias e trombopatias hereditárias do estado. Com a aposentadoria da profissional responsável pelos atendimentos odontológicos deste serviço, os pacientes ficaram desassistidos. Para suprir a demanda reprimida, o ambulatório foi reaberto como atividade extramuros da graduação e pós-graduação em Odontologia. Este fato possibilitou, além da retomada ao cuidado odontológicode pacientes com predisposição a hemorragias, o aprimoramento dos alunos no atendimento de pacientes com comprometimento sistêmico. A reabertura de um ambulatório de alta complexidade em saúde como campo de prática acadêmico é atípico, uma vez que comumente o processo se dá de forma inversa: o discente ingressando em um serviço bem estabelecido. Na presente experiência, os discentes tiveram atuação fundamental no restabelecimento da assistência à saúde pelo ambulatório de Odontologia do hemocentro (AU).

Debido a su mayor riesgo de hemorragia durante los procedimientos dentales, los pacientes diagnosticados con coagulopatías o trombopatías hereditarias a menudo tienen dificultades para acceder a la atención dental en la Atención Primaria de Salud. Algunos centros especializados en el tratamiento de estas enfermedades cuentan con el odontólogo como parte del equipo multidisciplinario, haciendo que la mayoría de los pacientes se sometan a un seguimiento odontológico en dichos servicios. Este estudio tiene como objetivo reportar la experiencia de estudiantes de pre y posgrado en Odontología de la Universidade Federal do Paraná en la reapertura de laconsulta externa de odontología para pacientes con coagulopatías y trombopatías hereditarias en el estado. Con la jubilación del profesional responsable de la atención odontológica de este servicio, los pacientes quedaron desatendidos. Para atender la demanda reprimida, se reabrió el ambulatorio como actividad extramuros para los cursos de grado y posgrado en Odontología. Este hecho posibilitó, además de la reanudación de la atención odontológica de los pacientes con predisposición a la hemorragia, la mejora de los estudiantes en la atención de los pacientes con deterioro sistémico. La reapertura de una clínica de salud de alta complejidad como campo de práctica académica es atípica, ya que el proceso comúnmente se da a la inversa: el estudiante ingresa a un servicio bien establecido. En la experiencia actual, los estudiantes tuvieron un papel fundamental en el restablecimiento de la atención de la salud por parte de la consulta externa de Odontología del Hemocentro (AU).

Due to their increased risk of bleeding during dental procedures, patients diagnosed with hereditary coagulopathies or thrombopathies often have difficulty in accessing dental care in primary health care. Some centres specialised in the treatment of these diseases have a dentist as part of the multidisciplinary team, making most patients undergo dental follow-up in such services. This study aims to report the experience of undergraduate and graduate students in dentistry at the Federal University of Paraná in the re-opening of the dental outpatient clinic for patients with hereditary coagulopathies and thrombopathies in the State of Paraná. With the retirement of the dentist accounting for local dental care, the patients were left unattended. To meet the repressed demand, the dental outpatient clinic was re-opened as an extramural activity for undergraduate and postgraduate courses in dentistry. This fact made it possible to improve the students' care for patients with systemic impairment, in addition to resuming dental care for patients with predisposition to haemorrhage. The re-opening of a highly complex clinic as a field of academic practice is atypical, as the process commonly takes place in reverse order, that is, with the student entering well-established service. In the present experience, the students played a fundamental role in the re-establishment of dental care at the blood centre (AU).

IL17A and IL17RA gene polymorphisms in Fanconi anemia.

Fanconi anemia is a rare autosomal recessive disease. In this disease, cytokine pathways can induce the bone marrow failure that is observed in individuals with Fanconi anemia. Interleukin IL-17 exhibits a protective effect in organisms because it induces neutrophil recruitment and shows a pathological role in several models of autoimmune diseases, periodontal disease, cancer, allograft rejection, and graft versus host disease. Polymorphisms in the IL17A and IL17RA genes were evaluated from DNA in saliva, comparing individuals with or without Fanconi anemia, using models of genotypic transmission (additive, dominant, and recessive). Polymorphisms in the IL17A and IL17RA genes (rs2241044 [C allele], rs879577 [C allele], rs9606615 [T allele], and rs2241043 [C allele]) were risk factors for developing Fanconi anemia. We also performed an analysis of gene markers with clinical variables in the Fanconi group. Polymorphisms in the IL17A gene (rs3819025 [A allele] and rs2275913 [G allele], respectively) were associated with an age of less than 20 years (p = 0.026; RP 0.65) and the female sex (p = 0.043; RP 0.88). The IL17RA gene was also associated with age and the presence of leukoplakia (a potentially malignant oral disorder). An age of less than 20 years was associated with rs917864 (T allele; p = 0.036; RP 0.67). The presence of leukoplakia was associated with rs17606615 (T allele; p = 0.042; RP 0.47). To our knowledge, this is the first study that associates IL17A and IL17RA gene polymorphisms with Fanconi anemia and examines rs2241044 polymorphisms in scientific literature thus far.

The effects of the cognitive bias of unrealistic optimism in the adoption of preventive measures against COVID-19 in dentistry.

Introduction: The bias of unrealistic optimism is people's tendency to believe that they are less likely to experience negative events than others. Dental professionals are part of a high-risk group for COVID-19. Objectives: The objective of this study is to investigate whether unrealistic optimism bias, concern, and regret can affect the adoption of preventive measures by these professionals. Methods: We conducted a cross-sectional observational study of dentists recruited remotely by using an electronic form sent by email and social media. A five-point scale was used to identify whether unrealistic optimism, concern, and regret affected the adoption of preventive measures. The study included a total of 339 dentists. The group considered to be unrealistically optimistic accounted for 24.8% of the sample. Results: Unrealistic optimism negatively affected the use of protective equipment by dental professionals. Conversely, concern positively affected preventive measures. Conclusions: Although most dentists are realistic about the risk of infection compared with their peers, those with optimistic bias might be more susceptible to the disease, as they tend not to adopt recommended protective measures in the workplace. Future studies should also investigate ways of debiasing.

Antimicrobial Photodynamic Therapy as a treatment option for inoperable cases of medication-related Osteonecrosis of the jaws.

The present study aims to report conservative treatment of an extreme case of MRONJ in a patient illegible for surgical treatment. A 69-year-old female patient, diagnosed with Multiple Myeloma underwent treatment with bisphosphonate. After a turbinectomy, she was referred to a dental clinic with painful oral symptoms, presence of necrotic and suppurative bone exposures in maxilla compatible with MRONJ. As surgery was not indicated, the treatment of option was to control infection and pain. PENTO protocol, antibiotic therapy and photodynamic therapy were instituted. The patient has been under dental follow-up for more than 1 year, with an important reduction in the areas of bone exposure, absence of active infection and painful symptoms, characterizing a significant improvement in the oral condition. The conservative approach achieved satisfactory results for the case, where the patient is ineligible for a surgery due to local and general conditions, and quality of life being prioritized.

Telehealth in Oral Medicine: report of an experience from public health care in a southern Brazilian state.

This study aimed to describe the telediagnosis of oral lesions through a telehealth program offered in the State of Paraná, southern Brazil. This report included all oral medicine-related teleconsultations between January 2015 and December 2019. Primary care dentists from the public health services of the state were trained to use the Telessaúde Brasil Redes platform, a national telehealth program that provides telediagnostic support through teleconsultations with specialists. Clinical information and images of oral lesions were solicited to each teleconsultation request. An oral medicine specialist evaluated the cases and provided diagnostic hypotheses, management, and referral suggestions. Finally, dentists were invited to evaluate the services. A total of 162 cases were submitted by 44 dentists. The patient's main complaint was described in 98.8% of cases, while the duration/evolution and the type of lesions were 64.81% and 40.12%, respectively. No images were attached to 19 (11.70%) patients. The information sent was sufficient for diagnostic reasoning in 125 (77.16%) requests. The specialist considered 78 cases (48.1%) to be resolved in primary care. Among respondents (45.7%), dentists considered that the teleconsultation "totally attended" their needs in 92% of requests. The description of the telehealth platform usage in oral medicine in Paraná showed the need to improve the participation of primary care dentists and the quality of clinical information provided as barriers to be overcome, aiming for the best usage of the platform.

Access to dental care for patients with inherited bleeding and hemoglobin disorders.

AIM: To identify the main barriers to dental care access for patients with inherited bleeding (IBD) and hemoglobin disorders (HbD). METHODS: Patients with IBD and HbD were invited to participate in this study between August 2019 and March 2020. Data were collected through a questionnaire consisting of socioeconomic and demographic items and questions about access to dental services and history of dental treatment. Univariate and multiple Poisson regression model was used to determine associations between professional refusal of dental care and other co-variables (p < .05). RESULTS: The participants (29.1%) have already had professional refusal of dental care and participants with IBD (53.2%) did not feel confident with their local dentist due to their bleeding tendency. Most (64.6%) felt apprehensive about visiting the local dentist and high prevalence of refusal to provide dental care was associated with age (prevalence ratio [PR] = 1.021; 95% confidence interval [CI] = 1.010-1.032). Individuals with low bleeding risk were less likely to be denied dental care by a professional compared to those with high bleeding risk (PR = 0.536; 95%CI = 0.291-0.990). CONCLUSION: Professional refusal of dental care was high among patients with IBD, particularly older adults and with an increased risk of bleeding.

Innovative reflection on oral cancer research priorities: the contribution of social network analysis.

The objective of this study is to present a tool to help understand how variables associated with oral cancer prevention relate to each other in a social network. A search of the Scopus database was performed using terms related to oral cancer and prevention from 2000 to 2020. The keywords were used as nodes and were analyzed using NodeXL, which produced the network graphic analysis. From the 1004 publications available, 4038 different keywords were obtained and then grouped into 75 constructs based on conceptual similarity. The most influential nodes were risk factors, comorbidities, epidemiology, and treatment. However, topics such as technology, telemedicine, self-examination, and diagnostic delay remain far removed from central relations. Network analysis enabled us to observe the bias of biological and basic science in the field and identify a need for studies concerning primary prevention, behavioral interventions, and inequalities in oral cancer.

Telediagnosis of oral lesions using smartphone photography.

OBJECTIVE: The objective of this observational study was to evaluate telediagnosis of oral lesions using smartphone photography. MATERIALS AND METHODS: Individuals with visible oral lesions composed a convenience sample. The lesions were photographed using a smartphone camera and emailed along with clinical information to three evaluators, who formulated up to two diagnostic hypotheses for each case. A total of 235 photographs from 113 clinical cases were obtained. The evaluators answered questions regarding referral decisions, requests for additional tests, diagnostic difficulties, and image quality. The diagnostic hypotheses were compared to the gold standard by means of percent agreement and kappa coefficient. Consensual face-to-face diagnoses of three specialists-when only a clinical diagnosis was necessary-or histopathological results-when a biopsy was necessary-were considered the gold standard. RESULTS: The telediagnosis was similar to the gold standard in 76% of the cases, and kappa coefficients showed almost perfect agreement (k = 0.817-0.903). The evaluators considered that referrals could have been avoided on an average of 35,4% of the cases. CONCLUSION: Diagnosis of oral lesions using images taken with a smartphone showed almost perfect agreement and diagnostic accuracy comparable to face-to-face diagnosis.

Graft-versus-host disease and herpes simplex virus oral injuries in onco-hematological patient: Case report.

INTRODUCTION: Graft-versus-host disease (GVHD) is a systemic complication that can affect patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) and the mouth is one of the places affected by the disease (oGVHD). Topical corticosteroids are used to control the painful symptoms, causing a local immunosuppression and increasing the risk for opportunistic infections. OBJECTIVE: This study aims to report a case of a 42-year-old woman, diagnosed with Chronic Myeloid Leukemia, who developed oGVHD and herpes simplex virus (HSV) infection after HSCT. CASE REPORT: oGVHD was confirmed by incisional biopsy and viral infection by HSV types 1 and 2 was confirmed by PCR. Topical and systemic corticotherapy and antiviral therapies were instituted. The immunosuppression intensified viral infection and antimicrobial photodynamic therapy (aPDT) was instituted as an adjuvant treatment. aPDT application, along with the patient's immune recovery, antivirals and corticosteroids resulted in clinical improvement of oral lesions. FINAL CONSIDERATIONS: This study highlights aPDT as an effective adjunct therapy in the local treatment of opportunistic infections in onco-hematological patients.

Self-perception of periodontal health status among individuals with Fanconi anemia

ABSTRACT Introduction: Fanconi anemia (FA) is a rare genetic disease characterized by congenital malformations and bone marrow failure. One of the most common oral diseases in individuals with FA is periodontitis and adequate self-perception of periodontal status could contribute to its prevention and early detection. Aim: To compare oral health self-perception, measured by a questionnaire, with the clinical oral condition of patients with FA. Methods and Results: Fifty-six patients with FA, over 11 years of age, answered a questionnaire about dental history and self-reported oral health. Decayed, missing, and filled teeth (DMFT), Visible Plaque Index (VPI) and Gingival Bleeding Index (GBI) were measured. The median age of participants was 21 years (min 11, max 44), 31 (55%) were females and 25 (45%) males. Thirty-five (62.5%) participants rated their oral condition as satisfactory and 7 (12.5%) participants reported tooth mobility, 10 (17.9%) exposed roots and 21 (37.5%) gingival bleeding. Clinical examination detected average DMFT = 5.23, VPI = 31.36% and GBI = 33.77%. The gingival bleeding report was more frequent among individuals with higher GBI (p = 0.014). The DMFT was higher in those who had already undergone dental treatments (p = 0.031). There was an association between participants who presented dental caries and who rated their oral health as poor (p = 0.03). The question "Do your gums bleed easily?" had good accuracy in the evaluation of periodontal disease (p = 0.68). Conclusion: Oral health self-perception of individuals with FA about gingival inflammation was associated with their gingival bleeding index.

Use of smartphone video calls in the diagnosis of oral lesions: Teleconsultations between a specialist and patients assisted by a general dentist.

BACKGROUND: Teleassistance in dentistry enables the support of dentists in areas without access to specialists. The aim of this study was to assess the feasibility and accuracy of synchronous teleconsultation in oral medicine. METHODS: Patients referred for specialized care owing to oral lesions were evaluated in person by a general dentist who obtained photographs of the lesions with a smartphone. The images were sent via a mobile application to an oral medicine specialist, with whom a video call was initiated on the same instant messaging application. After interviewing the patient, the specialist formulated a diagnostic hypothesis and suggestions for case management. Then a second specialist, blinded to the first evaluation, assessed the oral lesion in person and defined a diagnosis, which was considered as the reference standard. Diagnoses from the remote and the face-to-face consultations were compared in percentage levels of agreement and κ coefficient. RESULTS: Thirty-three patients, 25 through 83 years old, had 41 oral lesions. The average teleconsultation length was approximately 10 minutes. In 92.7% of the cases, there was concordance between the telediagnosis and the reference standard (κ = 0.922). CONCLUSIONS: Synchronous teleconsultation can provide reliable remote diagnosis through the support to primary care health care professionals in management of oral lesions. PRACTICAL IMPLICATIONS: Earlier diagnosis of malignancies, improvement of access for unassisted populations, and reduction of unnecessary referrals are possible practical implications of remote support of a specialist in the management and diagnosis of oral lesions.

Self-perception of periodontal health status among individuals with Fanconi anemia.

INTRODUCTION: Fanconi anemia (FA) is a rare genetic disease characterized by congenital malformations and bone marrow failure. One of the most common oral diseases in individuals with FA is periodontitis and adequate self-perception of periodontal status could contribute to its prevention and early detection. AIM: To compare oral health self-perception, measured by a questionnaire, with the clinical oral condition of patients with FA.

The DMFT was higher in those who had already undergone dental treatments (p =  0.031). There was an association between participants who presented dental caries and who rated their oral health as poor (p =  0.03). The question "Do your gums bleed easily?" had good accuracy in the evaluation of periodontal disease (p =  0.68). CONCLUSION: Oral health self-perception of individuals with FA about gingival inflammation was associated with their gingival bleeding index.

The interval since first symptoms until diagnosis of squamous cell carcinoma in the head and neck region is still a problem in southern Brazil

BACKGROUND: The aim was to examine the interval since first symptoms until final diagnosis of squamous cell carcinoma (SCC) in the head and neck region in southern Brazil. MATERIAL AND METHODS: The individuals were prospectively selected and underwent anamnesis, physical examination and interview in the first medical consultation at a Cancer Hospital from south of Brazil. RESULTS: From 488 patients who underwent clinical examination, 105 were included in the study with diagnosis of SCC. Patients average interval from first symptoms to final diagnosis was 152 days (median 86; max: 1105; min: 1), the average professional interval was 108 days (median: 97; max: 525; min: 1), and the average total period interval was 258 days (median: 186; max: 1177; min: 45). Factors statistically associated with patient and diagnosis itinerary intervals were smoking and poorly adapted dentures and distance from home to hospital, respectively. CONCLUSIONS: The identification of the itinerary characteristics of this specific population may reflect in more effective public policies, such as primary and secondary prevention programs, aiming to increase the survival of oncological patient. Furthermore, the knowledge of the variables that influence the late diagnosis minimizes patient's journey in search of care to cancer centers through health programs

Periodontal Attachment Loss in Children with Amegakaryocytic Purpura: Case Reports of Two Male Siblings.

AIMS: To report the periodontal condition of two siblings (ages 2 and 4) diagnosed with congenital Amegakaryocytic Purpura (AP), who underwent allogeneic hematopoietic stem cell transplant (HSCT) and developed graft-versus-host disease (GVHD) with oral manifestations. METHODS: Clinical history was obtained through physical examination and medical records. Patients received clinical and microbiological assessment at 2 months post-HSCT, when they started to show signs and symptoms of GVHD and were monitored at 8/15-months post-transplant. They were treated by means of prophylaxis and oral hygiene instruction. Two supragingival biofilm samples were collected from each patient and analyzed by Checkerboard DNA-DNA hybridization. RESULTS: Patients developed severe periodontal clinical attachment loss (CAL) in deciduous dentition associated with recession of the periodontal tissues. They also presented GVHD lesions in the oral mucosa, lips and tongue. Caries lesions, gingivitis, and heavy biofilm deposits were identified. The microbiological profile of biofilm samples presented high levels and proportions of periodontal pathogens, such as Aggregatibacter actinomycetemcomitans. CONCLUSION: The cases presented suggested that severe periodontal CAL in children with AP may be an atypical manifestation associated with AP and/or GVHD, which may be aggravated by the presence of a dysbiotic biofilm containing periodontal pathogens, especially A. actinomycetemcomitans.
