RESUMO

This review outlines the historical perspective, status, and future challenges of oral medicine (stomatology) in Brazil based on the records of the Brazilian Society of Stomatology and Oral Pathology (SOBEP) and the Brazilian Federal Dental Council as well as expert evidence input from academic leaders from 3 different generations of Brazilian oral medicine specialists. The beginning of oral medicine in Brazil dates to 1969, followed by the organization of SOBEP in 1974; however, official recognition as an independent specialty was achieved more recently within the Brazilian Federal Dental Council in 1992. After a 50-year maturation period of oral medicine in Brazil in terms of specialty crystallization across dentistry, medicine, and research, it is now time to follow the historical trends of the specialty internationally and establish a standard curriculum at a post-graduate level that will lead to uniformity of training for oral medicine in Brazil.

RESUMO

Good communication between clinicians and pathologists is a vital element in the diagnostic process, and poor communication can adversely affect patient care. There is a lack of research about communication in diagnostic oral and maxillofacial pathology. This narrative review explores different aspects of the quality of communication between clinicians and oral pathologists, with a focus on the diagnosis of oral and maxillofacial diseases. An electronic search was carried out in MEDLINE through the PubMed, Scopus, and Embase databases up to April 2021. No studies reporting communication, its adequacy or the required skills between clinicians and pathologists in oral diagnosis were found. According to studies published in medicine, strategies for improving communication skills include clinician-pathologist collaboration; a well-formatted, clear and thorough report; training in communication skills; and patient-centered care. Further studies evaluating the current practices and quality in oral and maxillofacial pathology are required to identify barriers and encourage optimal communication to facilitate diagnosis, as well as patient safety.

RESUMO

This study tested the hypothesis that head and neck radiotherapy (HNRT) impacts the immunoexpression of type I collagen, bone sialoprotein (BSP) and bone morphogenetic protein 4 (BMP4), thereby leading to micromorphological changes in the dentin-pulp complex (DPC), and promoting the onset and progression of radiation caries (RC). Twenty-two demineralized sections of carious teeth (a group of 11 irradiated teeth and a control group of 11 non-irradiated teeth) extracted from 19 head and neck cancer patients were analyzed by conventional optical microscopy and immunohistochemistry to investigate the micromorphology (cellular layer hierarchy, blood vessels, odontoblasts, fibroblasts, extracellular matrix, calcification, necrosis, reactionary dentin formation, and chronic inflammation), and the patterns of staining/immunolocalization of type I collagen, BSP and BMP4 in the dental pulp of irradiated and control samples. No significant differences attributable to the direct impact of radiotherapy were detected in DPC micromorphology between the groups. In addition, the patterns of immunohistochemical staining and immunolocalization of the proteins studied did not differ between the irradiated and the control samples for type I collagen, BSP or BMP4. This study rejected the hypothesis that HNRT directly damages dentition by changing the organic components and the microstructure of the DPC, ultimately leading to RC.

RESUMO

Smooth muscle neoplasms represent an important group of lesions which is rare in the oral cavity. Leiomyoma (LM) is benign smooth muscle/pericytic tumor usually presenting as non-aggressive neoplasm, while leiomyosarcoma (LMS) represents its malignant counterpart. The rarity of these lesions, together with its unspecific clinical presentation and a variable histopathological appearance, lead to a broad list of differential diagnoses, hampering their diagnoses. Therefore, in this study we describe the clinical and microscopic features of a series of oral and maxillofacial LMs and LMSs. A retrospective search from 2000 to 2019 was performed and all cases diagnosed as LM and LMS affecting the oral cavity and gnathic bones were retrieved. Clinical and demographic data were obtained from the patients' pathology records, while microscopic features and immunohistochemistry were reviewed and completed when necessary to confirm the diagnoses. Twenty-two LMs and five LMSs were obtained. In the LM group, males predominated, with a mean age of 45.7 years. The upper lip was the most affected site, and 18 cases were classified as angioleiomyomas and four as solid LM. In the LMS group, females predominated, with a mean age of 47.6 years. The mandible was the most affected site. Diffuse proliferation of spindle cells, with necrosis and mitotic figures, were frequent microscopic findings. LMs and LMSs were positive for α-smooth muscle actin, HHF-35 and h-caldesmon. In conclusion, oral LM/LMS are uncommon neoplasms with the latter usually presenting as metastatic disease. H&E evaluation may be very suggestive of oral LMs, but h-caldesmon staining is strongly recommended to confirm LMS diagnosis.

RESUMO

Neuroblastoma is the most common extracranial solid cancer of infancy, occurring mainly in the adrenal gland, with high metastatic potential. However, involvement of the head and neck region is rare. Here, we present two cases of metastatic neuroblastoma of childhood, in which a mandibular swelling was the first sign of disseminated disease. Case 1 describes a 4-year-old boy with a 2-week history of painful swelling in the left mandibular region, body soreness and weakness. Panoramic radiography and computed tomography showed a destructive lesion in the left mandibular ramus. Case 2 describes a 3-year-old boy with a 1-month history of swelling in the right mandibular area. Panoramic radiograph and cone-beam computed tomography showed a destructive lesion in the right body and ramus of the mandible, displacing tooth germs, with the destruction of vestibular and lingual bone cortices. In both cases, microscopic analyses revealed a diffuse proliferation of small, round, and blue cells with hyperchromatic nuclei and scant cytoplasm. While Case 1 was more undifferentiated, Case 2 presented eosinophilic areas suggestive of neuropil. A large immunohistochemical panel was performed, showing expression of neural markers such as CD56, neuron-specific enolase (in Case 2), chromogranin, and synaptophysin. Both lesions presented a high proliferation index (Ki67 > 70% and 80%, respectively). Positron emission tomography-computed tomography revealed ipsilateral adrenal primary lesions in both cases, with multiple bone metastatic lesions. Besides the mandible, multiple sites of the axial and appendicular skeleton were affected. Treatment consisted of induction chemotherapy, adrenalectomy, consolidation chemoradiotherapy, and post-consolidation therapy.

RESUMO

OBJECTIVE: The aim of this study was to estimate the frequency of oral leukoplakia and oral erythroplakia in young patients. STUDY DESIGN: The systematic review was based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and performed in the following electronic databases: PubMed, Scopus, and Embase. The studies included were cross-sectional, cohort, and diagnostic, which provided with clinical and microscopic data of patients younger than 40 years. The Critical Appraisal Checklist for Prevalence Studies from the Joanna Briggs Institute and the Quality Assessment Tool for Diagnostic Accuracy Studies were used to assess the risk of bias. RESULTS: Five studies met eligibility criteria and were included. The total number of patients from the studies was 1246, of which 115 were young patients (9.2%) with oral leukoplakia as the only oral potentially malignant disorder reported. Oral epithelial dysplasia was identified in 40 cases (34.7%), of which 8 (6.9%) presented malignant transformation. CONCLUSIONS: The frequency of oral leukoplakia is low in young patients. Observational studies are necessary for understanding oral leukoplakia and other oral potentially malignant disorders in younger patients.

RESUMO

OBJECTIVES: to provide accurate information about the global prevalence of human papillomavirus (HPV) in oropharyngeal squamous cell carcinomas (OPSCC). MATERIAL AND METHODS: a systematic review was performed using three main electronic databases. Studies were independently assessed by two reviewers based on established eligibility criteria, to identify the prevalence of HPV-driven OPSCC following criteria defined by the American Society of Clinical Oncology. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. Statistical software MedCalc was used to perform meta-analyses. RESULTS: from 2215 records found, 15 were included, reporting data from 6009 patients (time period range: 1980-2016), distributed in 11 countries. Eleven studies were considered as presenting low risk, and four as moderate risk of bias. Using proportion meta-analysis, pooled prevalence of HPV-driven OPSCC was 44.8 % (95 %CI: 36.4-53.5 %; i2 = 97.6 %), with the highest rates in New Zealand (74.5 %; 95 %CI: 60.9-85.3 %), and the lowest in Brazil (11.1 %; 95 %CI: 4.5-21.5 %). HPV prevalence was similar between males (45.7 %; 95 %CI: 36.5-55.0 %; i2 = 96.4 %) and females (42.2 %; 95 %CI: 34.3-50.5 %; i2 = 85.4 %). Mean/median age ranged from 59.1-67.1 years in the HPV-negative group, and from 55.7-63.5 years in the HPV-positive group. There was an overall discordance between testing by p16 (49.4 %; 95 %CI, 38.2-60.5 %; i2 = 96.2 %) and p16+ISH/PCR (44.7 %; 95 %CI, 33.5-56.2 %; i2 = 96.4 %). CONCLUSION: Overall pooled prevalence of HPV-driven OPSCC was approximately 45 %, with similar distribution among males and females. Double p16/HPV-DNA/RNA testing may be considered to increase specificity and prognostic accuracy.

RESUMO

BACKGROUND: The aim of this work was to evaluate the microscopic characteristics through polarized light microscopy, scanning electron microscopy and the mineral content of circumpulpal dentin of irradiated (IT) and non-irradiated teeth (NIT), with deep caries that reached the root canal. MATERIAL AND METHODS: A total of 25 IT were analyzed macroscopically, and radiographed. 5 NIT were used as controls. Two 100-µm-thick sections, per specimen, were evaluated in a polarized light microscopy and a scanning electron microscope. Demographics and clinical data were collected. RESULTS: The results did not demonstrate distinct morphology of the IT compared with NIT. Mineral content values by weight percentage of Ca and P were also similar, corresponding to 66.65% and 33.21% in the IT and 66.60% and 33.29% in the NIT. The Ca/P ratio did not show statistical differences between groups being respectively 2.74 and 2.72, in the IT and NIT (p> 0.05). CONCLUSIONS: Radiotherapy does not change morphology and mineral content of circumpulpal dentin in IT. Key words:Root canal, radiation-related caries, polarization microscopy, scanning electron microscopy, radiotherapy, oral neoplasms, dentin.

RESUMO

BACKGROUND: Incidence and mortality rates of childhood cancer represent a global public health issue, however, the worldwide prevalence of head and neck cancer in pediatric patients (HNCPP) is still unknown. Therefore, this study aimed to describe the frequency and distribution of HNCPP worldwide. METHODS: A specific search strategy was performed using MEDLINE, Scopus, and EMBASE to include studies based on hospital records, national cancer registries, and pathology files. Studies quality was assessed using the risk of bias checklist of the Joanna Briggs Institute Critical Appraisal. RESULTS: Nineteen publications (15,970 cases) were included. Global frequency ranged from 0.25 % to 15 %. Male patients older than 10 years of age were most affected by lymphomas, followed by carcinomas and sarcomas. Non-Hodgkin lymphoma, Hodgkin lymphoma, rhabdomyosarcoma, thyroid carcinoma, and nasopharyngeal carcinoma were the main histopathological subtypes. Neck/lymph nodes were anatomical hotspots. CONCLUSIONS: This HNCPP global overview may guide secondary prevention strategies and future etiological studies.

RESUMO

OBJECTIVE: This review aimed to explore the paradigms of disclosing a cancer diagnosis with a focus on oral and oropharyngeal cancer and patient-related considerations. STUDY DESIGN: A search of MEDLINE, Embase, and Scopus was conducted using the following keywords: oral cancer; mouth lesions; oncology; breaking bad news; truth disclosure; and communication skills training. English and Spanish language studies published through October 2019 were included. RESULTS: The way bad news is conveyed to patients with cancer may affect their comprehension of information, emotional distress, treatment adherence, and health outcomes. Models of communication that are focused on patients' preferences may result in better treatment outcomes. Available protocols, such as SPIKES and ABCDE, have useful recommendations for health care professionals communicating an oral cancer diagnosis. However, it is important to be attentive to the particular information needs of patients. CONCLUSIONS: When communicating a cancer diagnosis, providers should employ validated methods of information delivery and support for oncology patients. Further studies are needed to evaluate the experiences and preferences of patients with oral cancer during these communications.

RESUMO

OBJECTIVES: To evaluate cancer treatment-related toxicities in young head and neck cancer (HNC) patients. MATERIAL AND METHODS: A total of 44 patients were included in the present retrospective cohort study, which was designed to access oral toxicities of cancer treatment in young (< 45 years of age, Group I, n = 22) and old (> 58 years of age, Group II, n = 22) HNC patients with similar tumor stage and treatment protocols. Oral mucositis (OM), xerostomia, dysphagia, dysgeusia, trismus, and radiodermatitis were assessed during days 7th, 21st, and 35th of head and neck radiotherapy (HNRT) according to previously validated scales (World Health Organization criteria and the National Cancer Institute and Common Terminology Criteria for Adverse Events version 4.0). RESULTS: Patients from both groups showed high incidence and severity of oral toxicities by the end of the HNRT with OM (81.9% (Group I); 63.6% (Group II)) and xerostomia (72.6% (Group I); 77.2% (Group II)) being the most prevalent toxicities. No differences regarding xerostomia, dysphagia, dysgeusia, and radiodermatitis incidences or severity could be observed between groups. However, higher incidences and severity of OM at 21st and 35th fractions (odds ratio = 2.22 and 5.71, respectively) and trismus at 21st and 35th fractions (odds ratio = 6.17 and 14.5, respectively) were observed throughout the treatment in young patients when compared to older patients (p < 0.01 and p < 0.05, respectively). CONCLUSION: Young HNC patients are more affected by cancer treatment-related OM and trismus despite the similarities in clinical staging and treatment protocols with elderly patients.

RESUMO

Radiation-related caries (RRC) is a disease with a high potential for destruction of the dentition, which impairs quality of life in head-and-neck (HN) cancer (HNC) patients who undergo radiotherapy. In light of the recently described "clustering of oral symptoms theory," the present systematic review (PROSPERO CRD42019132709) aims to assess HN and gastrointestinal (GI) symptom clusters among HNC patients and discusses how these indirect effects of cancer therapy play a pivotal role in the pathophysiology of RRC. The search was performed at PubMed, Scopus, and Embase and resulted in 11 studies that met the inclusion criteria. Data extraction was performed with respect to the presence of HN/GI symptom clusters among HNC patients. The methodological data of the studies included were assessed using the MAStARI and GRADE instruments. The most prevalent reported HN symptoms were dysphagia, xerostomia, and pain. Taste alterations and fatigue were also commonly reported by the patients. Loss of appetite and weight loss were regularly reported in the studies, as well as nausea and vomiting. The results of the present study suggest that HNC treatment generates clusters of oral symptoms, leading to dietary changes, impaired oral hygiene, enamel fragility, and a highly cariogenic oral environment, which may impact the risk for RRC. A better understanding of oral symptom clustering could be of considerable clinical significance for the oral health and quality of life of HNC patients. Therefore, contemporary protocols of RRC prevention must take this broader treatment scenario of symptom clusters such as oral side effects into account.

RESUMO

BACKGROUND: Radiotherapy is widely used in contemporary head and neck cancer treatment protocols. The abil-ity of head and neck radiotherapy (HNRT) to cause direct radiogenic destruction to the teeth is one of the most controversial topics in the field of oral oncology. Therefore, this systematic review aimed to investigate ionising radiation as an independent factor for physical and chemical changes on the dentine-enamel junction (DEJ), a piv-otal dental topography for the onset and progression of radiation-related caries (RRC) and enamel delamination. MATERIAL AND METHODS: Systematic searches were conducted on three databases: Scopus, MEDLINE (Via PubMed) and Embase (Elsevier). Laboratory studies evaluating the effects of simulated or in vivo HNRT on the DEJ were included. The GRADE tool adapted for in vitro studies was used to assess the methodological quality. RESULTS: Of the 154 initially selected studies, eight met the inclusion criteria, from which five studies were graded as high quality of evidence, two studies were graded as moderate quality and one as low quality. Two studies did not demonstrate DEJ alterations following HNRT while the other six articles described several organic and inorganic changes in the DEJ of irradiated teeth samples. These radiogenic events were mostly detected through micro and na-noindentation, Raman micro-spectroscopy, confocal microscopy, Western blotting and optical coherence tomography. CONCLUSIONS: HNRT may have a negative impact on the physical and chemical aspects of the DEJ, predisposing can-cer patients to RRC and enamel delamination

RESUMO

OBJECTIVES: To establish a predictive clinical index of malignancy risk in palatal salivary gland tumors (PSGT). MATERIALS AND METHODS: One hundred cases of PSGT were evaluated. Clinical data were retrieved from the patient's files. Representative clinical photographs of each tumor were evaluated to identify clinical features suggestive of a malignant tumor. Features significantly associated with malignancy were included in a binary logistic regression model. RESULTS: Malignant tumors were more common in the hard palate, in women and in older patients. Features associated with a malignant diagnosis included pain (p = .017), irregular surface (p = .004), bluish/purple coloration (p < .001), ulceration (p = .005), and telangiectasia (p = .015). After multivariate logistic regression, pain (OR: 4.017; 95% CI: 1.198-13.471; p = .024) and color alteration (OR: 7.243; 95% CI: 2.068-25.363; p = .002) were independently associated with malignancy. Including these factors in a predictive index, the proportion of malignant tumors in patients presenting none, one and two factors were 25% (95% CI: 0.13-0.40), 67% (95% CI: 0.48-0.83), and 85% (95% CI: 0.42-0.99), respectively. CONCLUSION: Pain and color alteration might be independent predictors of malignancy in PSGT, which could support the decision to perform an incisional or excisional biopsy.

RESUMO

Photobiomodulation therapy (PBMT) has been considered an effective method for preventing and managing certain cancer-related toxicities in head and neck cancer (HNC) patients treated with radiotherapy and chemotherapy. However, the potential effects of PBMT on pain control and analgesia resulting from these toxicities is still controversial. The aim of this systematic review was to compile available evidence of the effects of PMBT on pain control and reduced use of analgesics in HNC patients. We searched three indexed databases: MEDLINE/PubMed, Embase, and Scopus. The databases were reviewed up to and including December 2018. Only human clinical studies in English language were selected. Information was only available for mucositis and radiodermatitis. Fifteen out of 1112 studies met the inclusion criteria (14 for oral mucositis (OM) and 1 for radiodermatitis). From the 14 studies involving the prevention and treatment of OM, 10 had the study subjects compared to a placebo group. Of these 10 studies, all but 1 showed statistically significant difference related to pain control favoring the PBMT group. The study that compared PBMT with other treatment modality showed better results in pain control with PBMT. It appears that PBMT application frequency and potency impact on pain control. The only study involving the prevention and treatment of radiodermatitis was compared to placebo arm and showed statistically significant difference related to pain control favoring the PBMT group. Seven studies compared the need of analgesic medication between PBMT and placebo groups. Of these, five studies showed that the use of analgesic medication was significantly higher in the placebo group. The current evidence supports that PBMT is effective in pain control resulting from OM and radiodermatitis and may also reduce the need for analgesics. The evidence is not yet available of the effects of PBMT in other HNC treatment-related toxicities.

RESUMO

Photobiomodulation therapy (PBMT), also known as low-level laser therapy (LLLT), has been increasingly used for the treatment of toxicities related to cancer treatment. One of the challenges for the universal acceptance of PBMT use in cancer patients is whether or not there is a potential for the light to stimulate the growth of residual malignant cells that evaded oncologic treatment, increasing the risk for tumor recurrences and development of a second primary tumor. Current science suggests promising effects of PBMT in the prevention and treatment of breast cancer-related lymphedema and oral mucositis, among other cancer treatment toxicities. Nevertheless, this seems to be the first systematic review to analyze the safety of the use of PBMT for the management of cancer-related toxicities. Scopus, MEDLINE/PubMed, and Embase were searched electronically. A total of 27 articles met the search criteria. Selected studies included the use of PBMT for prevention and treatment of oral mucositis, lymphedema, radiodermatitis, and peripheral neuropathy. Most studies showed that no side effects were observed with the use of PBMT. The results of this systematic review, based on current literature, suggest that the use of PBMT in the prevention and management of cancer treatment toxicities does not lead to the development of tumor safety issues.

RESUMO

Background: Radiation-related caries (RRC) is one of the most significant oral toxicities of head and neck radiotherapy (HNRT); however, the potential of radiation to directly cause harmful dentin and pulpal effects and impair response to caries progression is controversial. Material and Methods: Therefore, the aim of this study was to characterize the reactions of the dentin-pulp complex in teeth affected by RRC. Patients and methods: Twenty-two carious teeth extracted from 22 head and neck cancer (HNC) patients were divided into control (conventional caries; n=11) and irradiated (RRC; n=11) groups and paired matched by dental homology, clinical patterns of caries progression following the Post-Radiation Dental Index (PRDI) and microscopic depth of carious invasion. Histopathological characteristics based on morphological hierarchy, cell populations of dental pulp, blood vessels, neural elements, extracellular matrix components, inflammation, patterns of carious invasion and reactionary dentin presence were evaluated by optical light microscopy and histomorphometry. Results: Mean PRDI scores were 3.2 for the control group and 3.8 for the irradiated group. Dentin demineralization patterns were also similar between the groups and the mean depths of demineralization were 1,158.58µm and 1,056.89µm for the control and irradiated groups, respectively. Conclusions: Pulp histopathological changes and dentin reaction patterns were similar between groups and varied according to the PRDI scores and carious lesions depth. Dentin and pulp reactions are highly preserved in RRC teeth. Key words:Cancer, radiotherapy, radiation-related caries, teeth, pulp.

RESUMO

Validation studies of whole slide imaging (WSI) systems produce evidence regarding digital microscopy (DM). This systematic review aimed to provide information about the performance of WSI devices by evaluating intraobserver agreement reported in previously published studies as the best evidence to elucidate whether DM is reliable for primary diagnostic purposes. In addition, this review delineates the reasons for the occurrence of discordant diagnoses. Scopus, MEDLINE/PubMed, and Embase were searched electronically. A total of 13 articles were included. The total sample of 2145 had a majority of 695 (32.4%) cases from dermatopathology, followed by 200 (9.3%) cases from gastrointestinal pathology. Intraobserver agreements showed an excellent concordance, with values ranging from 87% to 98.3% (κ coefficient range 0.8-0.98). Ten studies (77%) reported a total of 128 disagreements. The remaining three studies (23%) did not report the exact number and nature of disagreements. Borderline/challenging cases were the most frequently reported reason for disagreements (53.8%). Six authors reported limitations of the equipment and/or limited image resolution as reasons for the discordant diagnoses. Within these articles, the reported pitfalls were as follows: difficulties in the identification of eosinophilic granular bodies in brain biopsies; eosinophils and nucleated red blood cells; and mitotic figures, nuclear details, and chromatin patterns in neuropathology specimens. The lack of image clarity was reported to be associated with difficulties in the identification of microorganisms (e.g., Candida albicans, Helicobacter pylori, and Giardia lamblia). However, authors stated that the intraobserver variances do not derive from technical limitations of WSI. A lack of clinical information was reported by four authors as a source for disagreements. Two studies (15.4%) reported poor quality of the biopsies, specifically small size of the biopsy material or inadequate routine laboratory processes as reasons for disagreements. One author (7.7%) indicated the lack of immunohistochemistry and special stains as a source for discordance. Furthermore, nine studies (69.2%) did not consider the performance of the digital method-limitations of the equipment, insufficient magnification/limited image resolution-as reasons for disagreements. To summarize the pitfalls of digital pathology practice and better address the root cause of the diagnostic discordance, we suggest a Categorization for Digital Pathology Discrepancies to be used in further validations studies. Among 99 discordances, only 37 (37.3%) had preferred diagnosis rendered by means of WSI. The risk of bias and applicability concerns were judged with the QUADAS-2. Two studies (15.4%) presented an unclear risk of bias in the sample selection domain and 2 (15.4%) presented a high risk of bias in the index test domain. Regarding applicability, all studies included were classified as a low concern in all domains. The included studies were optimally designed to validate WSI for general clinical use, providing evidence with confidence. In general, this systematic review showed a high concordance between diagnoses achieved by using WSI and conventional light microscope (CLM), summarizes difficulties related to specific findings of certain areas of pathology-including dermatopathology, pediatric pathology, neuropathology, and gastrointestinal pathology-and demonstrated that WSI can be used to render primary diagnoses in several subspecialties of human pathology.
