Relación entre la periodontitis y la enfermedad cerebrovascular isquémica

La periodontitis es un trastorno inmunoinflamatorio de etiología microbiana causado por gérmenes únicos en la cavidad bucal que pueden diseminarse a través del torrente sanguíneo, activan la respuesta inflamatoria del huésped y favorecen la formación, maduración y exacerbación de la placa de ateroma. Varios estudios clínicos han investigado la posible relación entre la enfermedad periodontal y las enfermedades consecuentes de la aterosclerosis como la cardiopatía isquémica y la enfermedad cerebrovascular isquémica. Se realizó una revisión bibliográfica exhaustiva de artículos científicos publicados en las bases de datos: Pubmed, Medline, LILACS, Scielo, en el período comprendido entre el 2012 y el 2022, en idioma español e inglés. Se utilizaron como descriptores: periodontitis, enfermedad cerebrovascular y aterosclerosis. Los reportes incluidos indican que la enfermedad cerebrovascular y la enfermedad aterosclerótica presentan las alteraciones con mayores asociaciones con la periodontitis, sin embargo, se necesitan estudios más amplios para determinar el papel de la severidad y extensión de la periodontitis en estas enfermedades.

Periodontitis is an immunoinflammatory disorder of microbial etiology caused by unique germs in the oral cavity that can spread through the bloodstream, activate the host's inflammatory response and promote the formation, maturation and exacerbation of atheromatous plaque. Several clinical studies have investigated the possible relationship between periodontal disease and diseases resulting from atherosclerosis such as ischemic heart disease and ischemic cerebrovascular disease. An exhaustive bibliographic review of scientific articles published in the databases: Pubmed, Medline, LILACS, Scielo, in the period between 2012 and 2022, in Spanish and English was carried out. The following were used as descriptors: periodontitis, cerebrovascular disease and atherosclerosis. The included reports indicate that cerebrovascular disease and atherosclerotic disease present the alterations with the greatest associations with periodontitis, however, larger studies are needed to determine the role of the severity and extent of periodontitis in these diseases.

Exodontia de supranumerário paramolar e de primeiro molar com destruição coronária em região de maxila: relato de caso / Extraction of a supernumerary paramolar and first molar with coronary destruction in the maxilla area: case report

Os dentes supranumerários são descritos como uma espécie de anomalia dentária, determinada pela formação de dentes além daqueles pertencentes à dentição convencional, que geralmente promovem complicações na cavidade oral. Diversos fatores etiológicos podem estar relacionados e de acordo com sua localização, são classificados em mesiodens, distomolar e paramolar. O presente estudo tem como objetivo apresentar e descrever a exodontia de um elemento supranumerário paramolar em região de maxila, bem como a remoção cirúrgica do primeiro molar com destruição coronária em região subjacente, através de um relato de caso. Paciente E.M.J., sexo feminino, 38 anos de idade, ASA 1, procurou atendimento odontológico devido à queixa principal de dor em região do 1° molar superior esquerdo. Ao exame físico e radiográfico, foi observada grande destruição coronária do elemento 26 associado a uma fístula intraoral, além da presença de dente supranumerário paramolar na região vestibular do dente 26. O tratamento preconizado foi a remoção cirúrgica de ambos elementos e a paciente evoluiu sem intercorrências no pós-operatório. Desta maneira, pode-se concluir que a remoção cirúrgica de dente supranumerário paramolar e de unidade dentária com grande destruição coronária por lesão cariosa, mostrou-se uma alternativa segura e eficaz no presente caso.

Supernumerary teeth are described as a kind of dental anomaly, determined by the teeth´s formation other than those belonging to the conventional dentition, which generally promote complications in the oral cavity. Several etiological factors may be related and, according to their location, they are classified into mesiodens, distomolar and paramolar. This study aims to present and describe the extraction of a paramolar supernumerary element in the maxillary region, as well as the surgical removal of the first molar with coronary destruction in the underlying region, through a case report. Patient E.M.J., female, 38 years old, ASA 1, sought dental care due to the main complaint of pain in the region of the upper left 1st molar. At the clinical and radiographic examination, a great coronal destruction of element 26 associated with a intraoral fistula was observed, in addition to the presence of a supernumerary paramolar tooth on the buccal side of tooth 26. The recommended treatment was the surgical removal of both elements and the patient evolved uneventfully in the post-operative. Thus, it can be concluded that the surgical removal of a supernumerary paramolar tooth and a dental unit with great coronary destruction due to a carious lesion proved to be a safe and effective alternative in the present case.

Experience with 808-nm diode laser in the treatment of 47 cases of oral vascular anomalies

Abstract Treatment of oral vascular anomalies (OVA) has focused on minimally invasive techniques rather than radical surgery. We investigated the efficacy and safety of diode laser using the photocoagulation technique in the management of OVA. Forty-seven subjects with OVA were treated with forced dehydration with induced photocoagulation (FDIP) using diode laser (808 nm/4.5 W). This series consisted mostly of male (63.8%) and non-white (63.8%) patients with a mean age of 57.4 years. Varices (91.5%), venous malformations (6.4%), and hemangiomas (2.1%) with a mean size of 7.1 (±4.9) mm were the conditions treated. OVA presented as a nodular lesion (63.8%) involving mainly the lower lip (46.8%). Pulsed laser mode was used as standard and the number of applications varied from one to four sessions, with the majority requiring only one (83%) FDIP session. Kaplan-Meier analysis revealed that complete clinical healing can occur on the 15th day (n=9/29.5%), followed by the 20th (n=6/45.5%), and 30th (n=7/70.5%) days. Postoperative edema was observed in 31 (66%) patients, and recurrence of the lesion occurred in two (4.2%). Based on the data on complete clinical healing, minimal patient discomfort, and satisfactory esthetic results, we can confirm that FDIP by diode laser is a promising candidate for the safe and efficacious treatment of OVA.

Oral health of an indigenous population in northeastern Brazil: a cross-sectional Study of the Fulni-ô ethnic group

ABSTRACT BACKGROUND: There is a lack of studies evaluating the oral health of traditional indigenous communities in Brazil. OBJECTIVES: Thus, the objective of this study was to describe the oral health characteristics of the indigenous Fulni-ô ethnic group in Northeast Brazil. DESIGN AND SETTING: A cross-sectional observational investigation was conducted within the Project on Atherosclerosis among Indigenous Populations. METHODS: This study included participants of both sexes from the Fulni-ô ethnic group. The participants included in this investigation underwent a comprehensive oral health evaluation by a registered and experienced dentist to assess oral health and identify potentially malignant oral lesions. Participants with suspicious lesions were referred for biopsy. Shapiro-Wilk, Mann-Whitney, and Student's t-tests were used, and measures of central tendency and dispersion were described. Statistical significance was 5%. RESULTS: A total of 104 individuals were included in this study. The prevalence of the use of tobacco derivatives was 94.0%, with similarities between sexes. The prevalence of oral changes in this study population was 84.4%. Fifty-one individuals who underwent oral reassessment were referred for oral lesion biopsy. CONCLUSIONS: This study demonstrated a high prevalence of oral alterations in the Fulni-ô population. Histopathological analyses indicated the presence of mild oral epithelial dysplasia in five cases.

Santé bucco-dentaire des enfants diabétiques: aspects épidémiologiques et cliniques au centre hospitalier universitaire Donka / Oral health of children with diabetes: epidemiological and clinical aspects at Donka University hospital

Le diabète sucré est l'une des pathologies chroniques les plus rependues chez l'enfant à cause de son apparition dans la tranche d'âge pédiatrique. Les lésions gingivales liées à la micro-angiopathie et la présence du tartre sont exceptionnelles chez l'enfant. La parodontopathie peut rendre plus difficile le contrôle de la glycémie. Les données actuelles de la littérature ont révélé qu'un enfant diabétique est plus susceptible de développer une pathologie bucco-dentaire qu'un enfant non diabétique. L'objectif de cette étude était d'évaluer l'état de santé bucco-dentaire des enfants diabétiques suivis dans le service d'Endocrinologie à l'hôpital National Donka. Il s'agissait d'une étude transversale de type descriptif et analytique, portant sur les affections orales et métaboliques des enfants diabétiques suivis ou hospitalisés dans le service d'Endocrinologie par un recrutement exhaustif sur une période de 6 mois. La population cible était composée de 72 enfants âgés de 6 à 18 ans au moment de l'étude. Un questionnaire a été utilisé pour obtenir des données sur le niveau socio-économique, le niveau sociodémographique, le niveau comportemental, les habitudes d'hygiène bucco-dentaire et les antécédents familiaux associés à un examen oral. Les paramètres diabétiques sont contenus dans le dossier médical. L'impact du diabète sur l'état oral des jeunes patients a été étudié par des variables qualitative et quantitative. Une corrélation entre l'ancienneté du diabète et l'indice d'hygiène orale simplifiée (p<0,05) a été observée avec p=0,03. IC95% [0,00 ; 0,06]. Mais aucun lien statistique n'a été enregistré entre la tranche d'âge et l'IHOS, d'autre part entre et aussi l'IHOS et la présence de variable clinique (p>0,05). La plupart des bouches présentaient des lésions carieuses avec un taux de 91,98% et un indice C.A.O moyen de 2,94 ± 2,82. Une gencive inflammatoire était présente chez 84,73% des patients et presque tous (95,83%) avaient une affection buccale au moins. La maladie bucco-dentaire est un marqueur social, les enfants diabétiques issus de milieux défavorisés doivent donc être ciblés plus particulièrement par les programmes de prévention

Diabetes mellitus is one of the most common chronic pathologies in children because of its appearance in the pediatric age group. Gingival lesions linked to microangiopathy and the presence of tartar are exceptional in children. Periodontal disease can make it more difficult to control blood sugar. Current data from the literature has revealed that a diabetic child is more likely to develop an oral pathology than a non-diabetic child. The objective of this study was to assess the oral health status of diabetic children followed in the endocrinology department at the national donka hospital. This was a descriptive and analytical cross-sectional study on the oral and metabolic disorders of diabetic children followed or hospitalized in the endocrinology department by exhaustive recruitment over a period of 6 months. The target population consisted of 72 children aged 6 to 18 at the time of the study. A questionnaire was used to obtain data on socioeconomic level, sociodemographic level, behavioral level, oral hygiene habits and family history associated with an oral examination. The diabetic parameters are contained in the medical file. The impact of diabetes on the oral status of young patients was studied by qualitative and quantitative variables. A correlation between the duration of diabetes and the simplified oral hygiene index (p0.05). Most of the mouths presented carious lesions with a rate of 91.98% and an average c.a.o index of 2.94 ± 2.82. Inflammatory gingiva was present in 84.73% of patients and almost all (95.83%) had at least one oral condition. Oral disease is a social marker, diabetic children from disadvantaged backgrounds must therefore be targeted more specifically by prevention programs.

Infecciones orales por VPH en personas HIV positivas de Corrientes, Argentina / Oral HPV infection in HIV-positive persons from Cor rientes, Argentina

Resumen Introducción : Las infecciones por virus del papiloma humano (VPH) en cavidad oral se asocian a un subgrupo de cánceres cuya prevalencia está en incremento en todo el mundo. Las personas portadoras HIV (PHIV) tienen un mayor riesgo de contraer una infección por VPH y eventualmente desarrollar cáncer. El presente estudio trata de relevar la frecuencia y variabilidad genotípica de dicho virus en cavidad oral y su asociación con pro bables factores de riesgo en una población HIV+ de la provincia de Corrientes. Métodos : Se tomaron enjuagados bucales de 133 participantes. Luego de la extracción de ADN se detectó por PCR anidada la presencia de VPH. Los casos positivos se tipificaron por Reverse Line Blot y por secuenciación. Resultados : En la serie analizada se detectó una fre cuencia global de VPH del 22% (29/133) en los enjuagados bucales. El 62% (18/29) de los casos positivos presentó al menos un genotipo de alto riesgo. Los participantes con más de 36 años (p = 0.03, aOR = 3.2, IC = 1.1-9,4) y una carga viral de más de 40 copias/mL (p = 0.04, aOR = 3.3, IC = 1.1-10.3) reflejaron mayor riesgo de infección por VPH. La edad de inicio de relaciones sexuales también resultó un indicador útil en los casos que presenta ron infecciones por genotipos de alto riesgo (p = 0.04, aOR = 7.2, IC = 1.6-32.3). Además, se observaron genotipos de bajo riesgo no reportados con anterioridad en cavidad oral de habitantes de la región (VPH-13 y VPH-114). Discusión : Relevar datos epidemiológicos basales en pobla ciones vulnerables y altamente expuestas a VPH ayuda a clarificar la historia natural del virus en localizaciones extragenitales y a focalizarnos en particularidades regio nales que permitan elaborar políticas de salud acordes a la magnitud del problema local.

Abstract Introduction : Oral cavity HPV infections are associ ated with a subgroup of cancers whose prevalence is increasing worldwide. HIV infected people are in an increased risk of contracting HPV infection and devel oping cancer. The present study reveals the frequency and genotypic variability of this virus in the oral cavity and its association with probable risk factors in an HIV+ population of the province of Corrientes. Methods : Mouthwashes were taken from 133 partici pants. After DNA extraction, the presence of HPV was detected by nested PCR. Positive cases were typed by reverse line blot or by sequencing. Results : HPV was detected in 22% (29/133) of the mouthwashes. In 62% (18/29) of the positive samples, at least one high-risk genotype was detected. Participants older than 36 years (p = 0.03, aOR = 3.2, CI = 1.1-9.4) and a viral load of more than 40 copies (p = 0.04, aOR = 3.3, CI = 1.1-10.3) had higher risk of infection by any HPV genotype. In relation to the age of initiation of sexual intercourse, it was a significant parameter in the case of patients with infections by high-risk genotypes (p = 0.04, aOR = 7.2, IC = 1.6-32.3). In addition, previously unreport ed low-risk genotypes were observed in the oral cavity of inhabitants of the region like HPV-13 and HPV-114. Discussion : Collecting baseline epidemiological data in this type of vulnerable population helps to clarify the natural history of the virus in extragenital locations and focus on regional particularities that allow the development of health policies in accordance with the magnitude of the regional problem.

Solitary fibrous tumor: Two cases report with a focus on the differential diagnosis / Tumor Fibroso Solitário: Relato de dois casos com foco no diagnóstico diferencial

Solitary fibrous tumor (SFT) is a neoplasm of fibroblastic/myofibroblastic origin with intermediate biological behavior. We report here two cases of SFT affecting an unusual anatomical site in 58-year-old and 40-year-old female patients and discuss the differential diagnosis of this lesion. In case 01, the lesion showed the clinical appearance of an asymptomatic "blister" with normal color, rubbery consistency, measuring 0.3 cm, and affected the lower lip; while in case 02, a symptomatic red nodular lesion with a soft consistency and measuring 0.5 cm affected the floor of the mouth. Excisional biopsies were performed. Microscopically, two well-delimited benign neoplasms were observed, exhibiting the proliferation of ovoid to spindle-shaped mesenchymal cells, vascular spaces with staghorn arrangement, and the absence of mitosis figures. Immunohistochemistry was performed in case 01 to assist in the diagnosis. Weak and diffuse immunostaining was observed for α-SMA and intense and diffuse immunopositivity for Bcl-2 and CD34. Based on histopathological and immunohistochemical features, a diagnosis of SFT was rendered in both cases. The low occurrence and nonspecific clinical features of oral SFT may make its clinical diagnosis difficult. Also, morphological and immunohistochemical are essential for differential diagnosis with other mesenchymal neoplasms.(AU)

O tumor fibroso solitário (TFS) é uma neoplasia de origem fibroblástica/miofibroblastica com comportamento biológico intermediário. Nesse artigo relatamos dois casos de TFS afetando sítios anatômicos incomuns em pacientes do sexo feminino de 58 anos e 40 anos e discutir os seus diagnósticos. No caso 01 clinicamente a lesão apresentou um aspecto de "bolha" assintomática, coloração normal da mucosa, consistência borrachoide medindo 0,3 cm, em região de lábio inferior, enquanto que no caso 02, como uma lesão sintomática, vermelha, nodular com consistência mole e medindo 0,5 cm afetando o assoalho bucal. As biópsias excecionais foram realizadas. Microscopicamente, observamos duas lesões neoplásicas bem delimitadas exibindo uma proliferação de células mesenquimais variando de ovoides a fusiformes, vasos sanguíneos em formato de "chifre de veado", com ausência de figuras de mitoses. No caso 01 foi realizado análise imuno-histoquímica para auxiliar no diagnóstico. Foi observado uma marcação fraca e difusa de α-SMA e uma intensa e difusa imunopositividade para o Bcl-2 e CD34.Baseado nos achados histopatológicos e imuno-histoquímicos o diagnóstico de TFS foi estabelecido em ambos os casos. A baixa ocorrência e os achados clínicos inespecíficos do TFS oral podem dificultar o diagnóstico clínico. Além disso, as análises morfológicas e imuno-histoquimicas são essenciais para realização do diagnóstico diferencial com outras neoplasias mesenquimais.(AU)_

Frecuencia de Bacilos Gram Negativos en la cavidad bucal de estudiantes de una Universidad de Asunción

Introducción: La cavidad bucal hospeda una gran cantidad de microorganismos, como los bacilos Gram negativos, y entre ellas, bacterias de gran importancia médica debido a su capacidad de producir enfermedades graves para el ser humano, especialmente en pacientes inmunodeprimidos. El objetivo de este trabajo fue determinar la presencia de Bacilos Gram Negativos y sus patrones de resistencia a antibióticos, en una población estudiantil de la ciudad de Asunción, en los años 2019 y 2020. Materiales y métodos: Se realizó un estudio observacional, descriptivo de corte transversal, donde se realizaron hisopados de la cavidad bucal a 35 alumnos de entre 18 a 24 años, de una universidad privada en la ciudad de Asunción. Se requirió consentimiento informado firmado por los participantes y fueron excluidos quienes tuvieron tratamientos antibióticos. Las muestras fueron obtenidas con un hisopo de algodón, posteriormente se colocaron en un medio de transporte para luego ser cultivadas en Agar MacConkey. El cultivo se realizó por 48 horas a 37° centígrados, luego se procedió a la identificación bacteriana. Por último, se realizó el antibiograma. Resultados: De los 35 alumnos se encontró una frecuencia de 48,57% de bacilos Gram negativos. Cepas de Klebsiella pneumoniae fueron las más frecuentes (35,29%). Se observó que las bacterias eran altamente resistentes a la Amoxicilina/Ácido Clavulánico. Conclusiones: La presencia de estos tipos de microorganismos puede ser peligrosa para la salud general de las personas, específicamente de los pacientes con algún tipo de inmunodepresión, debido a la gran la resistencia a antibióticos presentadas por algunas cepas.

Introduction: The oral cavity hosts a large number of microorganisms, such as Gram negative bacilli, and among them, bacteria of great medical importance due to their capacity to cause serious diseases for humans, especially in immunosuppressed patients. The objective of this work was to determine the presence of Gram Negative Bacilli and their patterns of resistance to antibiotics, in a student population of the city of Asunción, in the years 2019 and 2020. Materials and methods: An observational, descriptive cross-sectional study was carried out, where oral cavity swabs were made from 35 students between 18 and 24 years of age, from a private university in the city of Asunción. Informed consent signed by the participants was required and those who had antibiotic treatments were excluded. The samples were obtained with a cotton swab, later they were placed in a transport medium to later be cultured in MacConkey Agar. The culture was carried out for 48 hours at 37° Celsius, then the bacterial identification was carried out. Finally, the antibiogram was performed. Results: Of the 35 students, a frequency of 48,57% of Gram negative bacilli was found. Klebsiella pneumoniae strains were the most frequent (35.29%). The bacteria were found to be highly resistant to Amoxicillin/Clavulanic Acid. Conclusions: The presence of these types of microorganisms can be dangerous for the general health of people, specifically of patients with some type of immunosuppression, due to the great resistance to antibiotics presented by some strains.

Aplicação da fotobiomodulação laser em úlceras traumáticas na cavidade oral: revisão integrativa da literatura / Laser photobiomodulation application in traumatic ulcers in the oral cavity: integrative literature review

As úlceras traumáticas representam uma condição benigna e recorrente que acomete a cavidade oral, com variação de tamanho e dimensão. Existem inúmeras terapias que podem ser empregadas com o objetivo de promover analgesia e(ou) reparo tecidual. A fotobiomodulação laser (FBML) tem adquirido espaço no manejo dessas lesões, por se tratar de um dispositivo minimamente invasivo e bem tolerado pelo organismo, além de atuar na bioestimulação, o que confere efeito analgésico, anti-inflamatório e cicatricial. Dessa maneira, o estudo tem como objetivo avaliar a aplicação terapêutica da FBML em úlceras traumáticas na cavidade oral. Tratou-se de uma revisão integrativa da literatura, com base na pesquisa de artigos científicos dos últimos nove anos, realizada nas plataformas LILACS, BVS, SciELO, PubMed, e Google Acadêmico, utilizando o cruzamento de Descritores em Ciências da Saúde (DeCS) e empregando o uso dos operador booleano "AND". De forma adicional, a busca livre foi realizada com vistas à complementação da fundamentação teórica. Um total de sete artigos foram incluídos na presente revisão integrativa, o que incluiu estudos em humanos e em modelo animal. Todos os estudos incluídos apresentaram resultados positivos com a utilização da FBML, que demonstrou efeito benéfico através de uma ou duas sessões, com indução do processo de cicatrização, melhora da sintomatologia dolorosa e da inflamação. A FBML foi capaz de melhorar o quadro clínico e histológico das úlceras traumáticas em cavidade oral, através da modulação da percepção da dor e da inflamação, aceleração da cicatrização e consequente regressão das lesões.

Traumatic ulcers represent a benign and recurrent condition that affects the oral cavity, varying in size and dimension. There are numerous therapies that can be used to promote analgesia and/or tissue repair. Laser photobiomodulation (FBML) has gained space in the management of these lesions, as it is a minimally invasive device that is well tolerated by the body, in addition to acting in biostimulation, which confers analgesic, anti-inflammatory and healing effects. Thus, the study aims to evaluate the therapeutic application of FBML in traumatic ulcers in the oral cavity. This was an integrative literature review, based on the research of scientific articles from the last nine years, carried out on the LILACS, BVS, SciELO, PubMed, and Google Scholar platforms, using the intersection of Health Sciences Descriptors (DeCS) and employing the use of the Boolean operator "AND". Additionally, the free search was carried out with a view to complementing the theoretical foundation. A total of seven articles were included in this integrative review, which included studies in humans and in an animal model. All included studies showed positive results with the use of FBML, which demonstrated a beneficial effect through one or two sessions, inducing the healing process, improving pain symptoms and inflammation. FBML was able to improve the clinical and histological picture of traumatic ulcers in the oral cavity, by modulating the perception of pain and inflammation, accelerating healing and consequent regression of the lesions.

Objective:To investigate clinical characteristics and factors influencing the prognosis of patients with mucosal melanoma.Methods:The clinical data of 49 patients with mucosal melanoma in Fujian Cancer Hospital from March 2012 to March 2022 were retrospectively analyzed, and their clinical characteristics and prognostic influencing factors were observed. Kaplan‐Meier method was used for survival analysis and Cox proportional risk model was used to analyze the prognostic influencing factors.Results:Female accounted for 61.2% (30/49) of all 49 patients with mucosal melanoma and the median age was 56 years (42-79 years). The most frequent primary tumor sites occurred in head and neck (42.9%, 21/49), followed by the reproductive system (32.7%, 16/49). At the time of initial diagnosis, 81.6% (40/49) of patients had no distant metastasis and 79.6% (39/49) of patients had normal levels of peripheral blood lactate dehydrogenase. The median overall survival time of 49 patients with mucosal melanoma was 39.5 months (95% CI 23.1-55.9 months). The median overall survival time of patients without distant metastasis at the time of initial diagnosis was significantly longer than that of patients with distant metastasis [46.5 months (95% CI 31.6-61.4 months) vs. 19.2 months (95% CI 0-42.2 months, P = 0.025]. There were no statistically significant differences in median overall survival time of patients with different gender, age at the time of initial diagnosis, primary tumor site, and the level of lactate dehydrogenase in peripheral blood at the time of initial diagnosis (all P > 0.05). The presence of distant metastasis at the time of initial diagnosis was an independent risk factor for the prognosis of patients with mucosal melanoma ( HR = 0.379, 95% CI 0.157-0.918, P = 0.032). Conclusions:Mucosal melanoma is more common in female. The most frequent primary tumor sites occur in head and neck. At the time of initial diagnosis, most patients have non‐distant metastasis and the normal level of peripheral blood lactate dehydrogenase. At the time of initial diagnosis, whether there is distant metastasis is an independent influencing factor for the prognosis of patients with mucosal melanoma.

Pyogenic granuloma of the gums and lips caused by camrelizumab: case report and literature review / 口腔疾病防治

Objective@# To investigate the clinical manifestations, pathological features, and treatment of oral and maxillofacial pyogenic granulomas induced by camrelizumab. @*Methods@# A case of pyogenic granuloma of the gums and lips caused by camrelizumab was reported along with a literature review. @*Results@# After 4 months of treatment with camrelizumab for liver cancer, the patient developed systemic reactive capillary hyperplasia (RCH), followed by multiple masses on the lower lip and gingiva. After periodontal therapy, the masses on the lower lip and the gingiva were removed, and camrelizumab administration was stopped. The pathological result was gingival pyogenic granuloma/granulomatous hemangioma. No new masses were found in the oral cavity during postoperative follow-up. A review of the literature showed that RCH is the most common adverse drug reaction to camrelizumab but it occurs infrequently in the oral cavity. At present, the etiology of RCH has not been clarified, but the research has shown that camrelizumab may trigger tissue proliferation into hemangiomas by activating vascular endothelial cells, and the combined use of camrelizumab is safer than single use. RCH is self-limiting and most cases resolve spontaneously after discontinuation of the drug. If the mass causes dysfunction, surgical excision is feasible.@*Conclusion @#Camrelizumab can cause oral and maxillofacial reactive capillary hyperplasia complicated by pyogenic granuloma.

Marginal versus Segmental Mandibulectomy in the Treatment of Oral Cavity Cancer: A Systematic Review and Meta-analysis

Abstract Introduction Oral cavity squamous cell carcinoma (OCSCC) is the most common malignancy in the oral cavity. Two types of mandibular resections have been described: the segmental mandibulectomy and the marginal mandibulectomy. Both may have a different impact over the quality of life, oncological prognosis, and functional or aesthetic result. Objectives The aim of this study was to systematically explore the literature to determine the survival outcomes and disease control rates in patients who underwent segmental or marginal mandibulectomy for OCSCC with histological evidence of cortical and medullary bone invasion. Data Synthesis This review involved a systematic search of the electronic databases MEDLINE/PUBMED, Google Scholar, Ovid Medline, Embase, and Scopus including articles from 1985 to 2019. Fifteen articles were included for qualitative analysis and 11 articles were considered for meta-analysis calculations. All of them correspond to retrospective cohort studies. Conclusion This systematic review reveals the low-level evidence regarding the impact over local control or survival according to the type of mandibulectomy. Our results need to be considered with precaution according to the limited evidence available. We just found difference regarding the 5-year disease-free survival, and a tendency in favor of segmental mandibulectomy was confirmed when medullary invasion was evident.

Mesenchymal tumours of the head and neck: a 10-year institutional archival study / Tumores mesenquimales de cabeza y cuello: estudio de archivo institucional de 10 años de duración

Introduction: Histopathological characterisation of benign and malignant lesions of the head and neck in a systematic and coherent way is an essential part of Oral Pathology and Oral Medicine. Objective: To describe the frequency and histopathological profile of connective tissue tumours in the head and neck region reported in an Indian institute. Methods: A retrospective analysis was made of the 10-year records of reports of biopsy samples of patients maintained by the department of oral pathology showing histopathological diagnosis of connective tissue neoplasms. The data obtained was compiled for age, gender, site and histopathology of the lesions. Results: Majority of the tumours were benign and patients were found to be in the 2nd or 4th decade of life with female preponderance. The most common benign tumour was fibroma where buccal mucosa was the commonest location and malignant tumour was osteosarcoma where mandible was the commonest site. While fibromas were seen among general adult population, osteosarcomas were more in the males (7.2 percent) and in the younger population (< 20 years). The uncommon tumours among benign variety were leiomyoma and teratoma while in malignant category 1 case of undifferentiated sarcoma was reported. Conclusion: The findings in this study may be of help to oral and maxillofacial surgeons and general dentists in formulating diagnosis and rendering patient care in the existing local population(AU)

Introducción: La caracterización histopatológica de las lesiones benignas y malignas de cabeza y cuello de forma sistemática y coherente es una parte esencial de la Patología Oral y la Medicina Oral. Objetivo: Describir la frecuencia y el perfil histopatológico de los tumores del tejido conjuntivo de la región de cabeza y cuello notificados en un instituto indio. Métodos: Se realizó un análisis retrospectivo de los registros de 10 años de informes de muestras de biopsia de pacientes mantenidos por el departamento de patología oral que mostraban diagnóstico histopatológico de neoplasias del tejido conectivo. Se recopilaron los datos obtenidos en cuanto a edad, sexo, localización e histopatología de las lesiones. Resultados: La mayoría de los tumores eran benignos y los pacientes se encontraban en la 2ª o 4ª década de la vida, con preponderancia del sexo femenino. El tumor benigno más frecuente fue el fibroma, cuya localización más frecuente fue la mucosa bucal, y el tumor maligno fue el osteosarcoma, cuya localización más frecuente fue la mandíbula. Mientras que los fibromas se observaron entre la población adulta general, los osteosarcomas fueron más frecuentes en los varones (7,2 por ciento) y en la población más joven (< 20 años). Los tumores menos frecuentes en la variedad benigna fueron el leiomioma y el teratoma, mientras que en la categoría maligna se registró un caso de sarcoma indiferenciado. Conclusiones: Los hallazgos de este estudio pueden ser de ayuda para los cirujanos orales y maxilofaciales y los odontólogos generales en la formulación de diagnósticos y la prestación de atención al paciente en la población local existente (AU)

Factores de riesgo, etapificación y pronóstico en carcinoma escamoso de cavidad oral / Risk factors, staging and prognosis in oral cavity squamous cell carcinoma

El carcinoma escamoso de cavidad oral corresponde a una de las neoplasias malignas más frecuentes en cabeza y cuello, teniendo una incidencia mundial según GLOBOCAN para el año 2020 de 377.713 casos nuevos. Este cáncer tiene la ventaja potencial de su diagnóstico precoz por su accesibilidad al examen físico, por lo que es importante tener un alto índice de sospecha en pacientes con los factores de riesgo como tabaquismo crónico, consumo de alcohol, consumo de nuez de betel, inmunodeficiencias, entre otros, teniendo una conducta activa con el fin de lograr un diagnóstico precoz. Por otro lado, la etapificación actual incorpora nuevos factores pronósticos, como la profundidad de invasión, con el fin de asignar de mejor forma una clasificación adecuada y con ello, guiar el tratamiento de estos pacientes. Finalmente, se debe procurar un diagnóstico y tratamiento precoz con el fin de lograr los mejores resultados oncológicos.

Squamous cell carcinoma of the oral cavity represents one of the most frequent malignant neoplasms in the head and neck, having an incidence according to GLOBOCAN for the year 2020 of 377,713 new cases. This cancer has the potential advantage of early diagnosis due to its accessibility to physical examination, so it is important to have a high index of suspicion in patients with risk factors such as chronic smoking, alcohol consumption, betel nut consumption, immunodeficiencies, among others, having an active behavior in order to achieve an early diagnosis. On the other hand, the current staging incorporates new prognostic factors, such as depth of invasion, in order to better assign an adequate classification and thus guide the treatment of these patients. Finally, early diagnosis and treatment should be sought in order to achieve the best oncological outcomes.

Nutritional and immunological parameters as prognostic factors in patients with advanced oral cancer

Abstract Objective: The aim of the present study was to analyze the prognostic relationship of weight loss and preoperative hematological indexes in patients surgically treated for pT4a squamous cell carcinoma of the oral cavity. Methods: A retrospective cohort study. Results: Percent weight loss greater than 10% was identified in 49 patients (28.2%), and any weight loss in relation to the usual weight occurred in 140 patients (78.7%). Percent weight loss greater than 10% (HR = 1.679), Red cell distribution width (RDW) values greater than 14.3% (HR = 2.210) and extracapsular spread (HR = 1.677) were independent variables associated with risk of death. Conclusion: Patients with advanced squamous cell carcinoma of the oral cavity present significant weight loss and as significantly immunocompromised. Increased values of RDW and higher percentages of weight loss in relation to the individual's usual weight, together with extracapsular spread of metastatic lymph nodes, were risk factors for lower survival, regardless of other clinical and anatomopathological characteristics. Level of evidence: 3.

Evaluation of oncological outcomes in patients with oral cavity cancer treated in a lowvolume hospital

Introduction: Oral cavity cancer (OCC) is one of the 10 most common types of tumors in the world. Surgical resection is the most indicated initial treatment, followed by adjuvant therapy, depending on tumor stage. A few studies have suggested that patients treated in high-volume hospitals present better oncologic outcomes; however, particularly in continental countries, some patients are treated in regional hospitals. Objective: To evaluate the results of OCC patients treated in low-volume regional hospitals. Methods: This is a retrospective longitudinal study conducted with patients diagnosed with OCC and operated on in a low-volume hospital between January 2003 and December 2018. Results: 174 patients with OCC were treated at the institution - an average of 11 patients/year. The most common tumor location was the tongue (48.2%), followed by the lip (18.2%). Squamous cell carcinomas were the most frequent (94.7% of patients). Adjuvant radiotherapy and chemotherapy were performed in 46.7 and 31.9% of patients, respectively. Almost 21% of patients had some postoperative complication. Specific survival of 62.6% and global survival of 58.2% after 3 years were similar to the results reported in high-volume centers. Disease-free survival was 45.8% in the same period. Conclusion: Low-volume hospitals qualified for oncological treatments can present outcomes similar to those of high-volume centers, and are thus a regional option for patients with OCC.
