Brazilian dental consensus on dental management in hematopoietic stem cell transplantation−Part I−pre-HSCT

ABSTRACT The oral involvement in the Hematopoietic Stem Cell Transplantation is well described in the literature. The goal of the dental treatment and management of the oral lesions related to the HSCT is to reduce the harm caused by preexisting oral infection or even the worsening of oral acute/chronic GVHD and late effects. The aim of this guideline was to discuss the dental management of patients subjected to HSCT, considering three phases of the HSCT: pre-HSCT, acute phase, and late phase. The literature published from 2010 to 2020 was reviewed in order to identify dental interventions in this patient population. The selected papers were divided into three groups: pre-HSCT, acute and late, and were reviewed by the SBTMO Dental Committee's members. When necessary, an expertise opinion was considered for better translating the guideline recommendations to our population dental characteristics. This manuscript focused on the pre-HSCT dental management. The objective of the pre-HSCT dental management is to identify possible dental situations that On behalf of the Dental Committee of the Brazilian Society of Gene Therapy and Bone Marrow Transplantation (SBTMO) can worsening during the acute phase after the HSCT. Each guideline recommendations were made considering the Dentistry Specialties. The clinical consensus on dental management prior to HSCT provides professional health caregivers with clinical setting-specific information to help with the management of dental problems in patients to be subjected to HSCT.

Queratocisto odontogênico em maxila: relato de caso

Objetivo: Relatar o processo de diagnóstico e tratamento de um queratocisto odontogênico (QO) em seio maxilar e a sua importância na investigação e diagnóstico de Síndrome de Gorlin-Goltz (SGG). Relato de caso: Paciente do gênero feminino, 20 anos, apresentou-se no serviço de odontologia encaminhada pela equipe de genética médica para investigar a presença de QO para definição de diagnóstico de SGG. Foi realizada radiografia panorâmica e verificou-se a presença de alterações no trabeculado ósseo em tuberosidade maxilar do lado esquerdo. Por isso, foi solicitada a tomografia computadorizada de seios maxilares e encontrou-se uma lesão bem delimitada, ocupando quase completamente o seio maxilar esquerdo em íntimo contato com a raiz do dente 27. Portanto, foi realizada biópsia incisional da lesão, acompanhada da aspiração do conteúdo. Na aspiração foi obtido um conteúdo de característica caseosa sugestivo de queratina. O laudo histopatológico da lesão foi de cisto odontogênico. Com isso, foram realizados os procedimentos de exodontia do dente 27 e a enucleação da lesão em seio maxilar pela equipe da odontologia e da otorrinolaringologia, respectivamente, em centro cirúrgico. O laudo histopatológico confirmou a presença de QO, assim foi possível confirmar o diagnóstico da SGG pela equipe da genética médica. A paciente não apresentou sinais de recidiva e nem de novos QO após 2 anos do procedimento. Considerações finais: A SGG requer atenção odontológica especial, visto a alta taxa de QO nos pacientes com essa síndrome. Exame odontológico minucioso envolvendo exame clínico e exames radiográficos devem ser realizado nas consultas de seguimento.

Objective: To report the process of diagnosis and treatment of an odontogenic keratocyst (OK) in the maxillary sinus and its importance in the investigation and diagnosis of Gorlin-Goltz Syndrome (GGS). Case report: A 20-year-old female patient presented at the Dentistry and Stomatology service, referred by the Medical Genetics team to investigate the presence of OK to define the diagnosis of GGS. Panoramic radiography was performed and the presence of alterations in the bone trabeculae in the maxillary tuberosity on the left side was verified. For this reason, computed tomography of the maxillary sinuses was also requested and a well-defined lesion was found, occupying almost completely the left maxillary sinus in close contact with the root of tooth 27. Therefore, an incisional biopsy of the lesion was performed, accompanied by puncture of the same. In the puncture, a characteristic caseous content suggestive of keratin was obtained. The histopathological report of the lesion was described by the pathologist as an odontogenic cyst. With this, tooth extraction procedures for tooth 27 and enucleation of the lesion in the maxillary sinus were carried out by the dentistry and otorhinolaryngology teams, respectively, in a surgical center. The histopathological report confirmed the presence of OK, so it was possible to confirm the diagnosis of GGS by the medical genetics team. The patient showed no signs of recurrence or new OK after 2 years of the procedure. Final considerations: GGS requires special dental attention, given the high rate of OK in patients with this syndrome. A thorough dental examination involving clinical examination and radiographic examinations should be performed at follow-up visits.

Assessment of oral health condition in recipients of allogeneic hematopoietic cell transplantation

ABSTRACT Objective: The objective of this study was to evaluate the oral health condition and dental treatments performed in patients in pre-allogeneic HCT. Method: The records of patients treated during 2018 at a Brazilian HCT service were reviewed. The following oral health data were obtained: 1. Decayed, missing and filled teeth / correlated index for primary dentition (DMFT/dmft); 2. Quality of oral hygiene and 3. Dental pathologies: 3.1 Periodontal infectious focus, 3.2 Endodontic infectious focus and 3.3 Carie incidence. All dental procedures performed were surveyed. Results: Thirty-three patients were included, with a mean age of 28.42 (±16.37), 20 male (60%) and 13 female. The average DMFT/dmft found in this study was 10.24 (± 8.37), similar to the index found in the population in southeastern Brazil. The younger study population presented a DMFT/dmft considered high, when compared to the general population. A total of 27.2% of the patients had active caries lesions, 33.3%, foci of periodontal infection, 15.1%, endodontic infectious focus and 40%, poor oral hygiene. Almost half of the patients (48.4%) had to undergo dental intervention, 24.2% needing periodontal scaling, 21.2%, fillings and 12.1%, tooth extractions. Conclusion: We conclude that the studied population had an important incidence of dental pathologies and infectious conditions that could complicate throughout HCT, especially in younger patients, therefore presenting a high demand for dental treatment in the pre-HCT. Studies that assess the impact of dental conditioning on the outcomes of HCT with an emphasis on dental infectious complications, days of hospitalization and survival are necessary."

Laryngeal Cancer Attributable Factors and the Influence on Survival Rates: A Single Brazilian Institution Experience

Abstract Introduction Epidemiological studies focused on prognostic factors associated with laryngeal cancer in the Brazilian population are poorly reported in the literature. Objective To evaluate the influence of certain risk factors on the survival rates of patients with squamous cell carcinoma (SCC) of the larynx. Methods This retrospective study was conducted on adult patients who were admitted to the outpatient clinic of the head and neck department in a tertiary care hospital. Evaluation of the influence of risk factors on the survival rates of patients registered in the hospital with laryngeal SCC was performed based on age, sex, initial stage, time of evolution, habits, educational levels and relapse and death. Overall survival (OS), disease-free survival (DFS) and clinical-demographic data were analyzed using the Kaplan-Meier method, Log-rank test and Cox regression. Results A total of 107 patients with a mean age of 59.8 years (range 19-81) were included in this study. Stages III and IV were associated with decreased DFS (p = 0.02) and OS (p = 0.02). Smoking patients had a greater period of disease evolution than non-smoking patients (p = 0.003). Alcohol consumption in smokers increased the risk of death by 2.8 (p = 0.002) compared with non-drinking smokers. Male patients presented lower DFS average when compared with female patients (p = 0.04). Conclusion Our study confirms that male gender, smoking habit combined with alcohol consumption, and advanced stages were strongly associated with poor prognosis.

Um despertar para a necessidade de aprimoramento dos profissionais da Atenção Básica à Saúde no diagnóstico de lesões orais / Awareness for need of improvement in knowledgement about oral lesions for professionals in primary health care

Objetivo: O objetivo desse estudo foi avaliar a eficácia do diagnóstico e tratamento de lesões orais entre diferentes níveis de saúde. Material e Métodos: Todas as informações foram obtidas dos prontuários médicos de um Hospital Universitário e de fichas do Sistema Público de Regulação, considerando as características clínico-demográficas tal como, doenças orais diagnosticadas, sistema de referência e terapia empregada. A avaliação foi baseada na relação entre diagnóstico final, hipótese diagnóstica e prioridade para agendamento da consulta, também foi considerado o tempo decorrido entre o encaminhamento e o primeiro atendimento, data do diagnóstico final e início da terapia. Depois, a hipótese diagnóstica preenchida por profissionais de saúde do nível primário e terciário foram comparadas e a concordância entre ambos foi determinada. Resultados: Cerca de 51% dos encaminhamentos preenchidos pelos profissionais da atenção primária estavam incompletos, ou a hipótese diagnóstica estava descrita de forma inadequada. No nível terciário, o tempo médio entre o encaminhamento e a primeira consulta foi de 23 dias, a média entre o diagnóstico final e o início do tratamento foi de 22 dias. O tratamento cirúrgico foi o mais rápido (31 dias) quando comparado a radioterapia para lesões malignas (81 a 100 dias). Conclusão: É necessário melhorar o treinamento de profissionais de saúde da Atenção Básica no reconhecimento de lesões orais malignas. Claramente, o preenchimento adequado das hipóteses de diagnóstico, com o grau de prioridade correspondente acelera o diagnóstico e tratamento do paciente.

Objective: this study aims to evaluate the efficacy of diagnosis and treatment of oral lesions between different healthcare levels. Material and Methods: all information was obtained from the medical records of a University Hospital and Public Health Regulation System regarding clinical-demographic features such as oral diseases diagnosed, referral system and therapy employed. Evaluation was based on the relationship between final diagnosis, diagnostic hypothesis and the priority of medical appointments, time between referral and first appointment, date of final diagnosis and therapy onset. Latter, diagnostic hypothesis fulfilled between primary and tertiary healthcare providers were compared and the agreement between both were determined. Results: about half (51%) of the medical forms filled by primary healthcare professionals were incomplete, or diagnostic hypothesis was inadequately described. At the tertiary healthcare level, mean time between referral and first appointment was 23 days, and mean time between the final diagnosis and treatment was 22 days. Surgical treatment was faster (31 days) when compared to radiotherapy for malignant lesions (81 to 100 days). Conclusion: it is necessary to improve training of healthcare professionals in the primary healthcare regarding the recognition of malignant oral lesions. Clearly, appropriate filling of the diagnostic hypothesis with the corresponding degree of priority accelerates the diagnosis and treatment of the patient.
