Abstract In the modern world, cancer is a growing cause of mortality, but archeological studies have shown that it is not exclusive to modern populations. The aim of this study is to examine the epidemiologic, social, and clinicopathologic features of head and neck cancers in ancient populations. To do this, we extracted all records that described malignant lesions in the head and neck region available in the Cancer Research in Ancient Bodies Database (CRAB). The estimated age, sex, physical condition of the remains (skeletonized, mummified), anatomic location of tumors, geographic location, chronology, tumor type, and methods of tumor diagnosis were collected. One hundred and sixty-seven cases were found, mostly originating from Europe (51.5%). Most records were of adults between 35 and 49 years of age (37.7%). The most involved site was the skullcap (60.4%), and the most common malignancies were metastases to the bone (65.3%) and multiple myeloma (17.4%). No primary soft tissue malignancies were registered. The results of our study indicate that head and neck cancers were present in ancient civilizations, at least since 500,000 BCE. The available data can help to improve the current understanding of the global distribution of head and neck cancer and its multidimensional impacts on populations in the contemporary world. world mortality epidemiologic social CRAB.

Abstract: Optimizing the quality of referral letters could be the first step to a correct clinical approach for patients. Referral letters should be legible and contain the necessary information to avoid delaying the patient's diagnosis and treatment. However, to date, few studies have been conducted on how referrals are performed in Brazil. Knowledge regarding the quality of referral letters can provide information to better guide health care professionals. This study was aimed at analyzing all referrals received by a single oral medicine service in Brazil. Referral letters were classified into poor, regular, good, and excellent based on key items concerning the primary morphology of the lesion, location, diagnostic hypothesis, symptomatology, time of evolution, consistency, size, and limits. A total of 500 referral letters were evaluated, including 271 (54.2%) from a private service and 229 (45.8%) from a public service. Dentists and physicians had written 475 (95%) and 25 (5%) referral letters, respectively. Among the 500 referrals analyzed in this study, the number of regular, poor, good, and excellent referrals was 236 (47.2%), 203 (40.6%), 58 (11.6%), and one (0.6%), respectively, showing a lack of important clinical information in referrals.

Resumo Tumor neuroectodérmico melanótico da infância (TNMI) é um neoplasma raro que afeta principalmente crianças com idade abaixo de 1 ano. Um menino de 4 meses foi referenciado para avaliação de uma lesão com 1 mês de evolução. O exame intra-oral detectou uma massa nodular submucosa firme à palpação, medindo 1,5 cm de diâmetro, afetando rebordo alveolar anterior da maxila e recoberta por mucosa de coloração levemente azulada com telangiectasia evidente. O paciente foi submetido à biopsia incisional e as análises histológica e imunohistoquímica revelaram ninhos compostos por células com abundante pigmento de melanina, positivas para AE1/AE3. Outro tipo celular, semelhante à neuroblastos, também estava presente e foram positivas para CD56, sinaptofisina e enolase. O diagnóstico de TNMI foi estabelecido e o paciente encaminhado para tratamento. Ressecção cirúrgica conservadora sob anestesia geral ao longo de 3 dentes adjacentes foi realizada. O paciente está em acompanhamento há 1 ano e meio sem sinais de recorrência. O tratamento cirúrgico conservador do TNMI pode ser uma alternativa à maxilectomia, contribuindo para a qualidade de vida do paciente.

Abstract Melanotic neuroectodermal tumor of infancy (MNTI) is a rare neoplasm that affects mainly children under 1 year of age. A 4-month-old boy was referred for evaluation of a lesion with 1 month of evolution. Intra-oral examination detected a firm upon palpation submucosal nodular mass, measuring 1.5 cm in diameter, affecting the anterior maxillary alveolar ridge and covered by a slightly blue mucosa with evident telangiectasia. The patient underwent an incisional biopsy and histological and immunohistochemical analyses revealed nests of AE1/AE3 positive epithelioid cells with abundant melanin pigmentation. Other cell types, resembling neuroblasts, were also present and positive for CD56, synaptophysin and enolase. The diagnosis of MNTI was established and the patient was referred for treatment. Conservative surgical resection was performed along with 3 adjacent teeth under general anesthesia. The patient is in follow-up for 1,5 year without recurrence. Conservative surgical management of MNTI may be an alternative to maxillectomy, contributing to the patient´s quality of life.

Resumo A miíase furuncular é uma infecção parasitária causada pelas larvas de insetos Dipterans após penetrar na pele saudável, causando um nódulo eritematoso contendo um poro central. Adicionalmente, uma sensação de movimento e dor intermitente pode ser sentida. Miíase furuncular acometendo a região oral e perioral é rara, frequentemente causando erros diagnósticos. Este artigo descreve um caso raro de miíase furuncular em um paciente do sexo masculino de 20 anos de idade que apresentou um nódulo eritematoso no lábio inferior. Uma cirurgia exploratória foi indicada para fins diagnósticos e curativos, com sucesso observado já na sessão seguinte. Após 3 anos de acompanhamento, o paciente está recuperado, sem sinais clínicos ou sintomas da doença.

Abstract Furuncular myiasis is a parasitic infection caused by the larvae of Dipteran insects after penetrating healthy skin, causing an erythematous nodule with a central pore. Additionally, the patient may feel a sensation of movement and intermittent pain. Furuncular myiasis affecting the oral and perioral region is rare, usually leading to misdiagnosis. This paper describes a rare case of furuncular myiasis in a 20-year-old healthy male patient who presented an erythematous nodule in the lower lip. An exploratory surgery was indicated for both diagnostic and curative purposes, with successful healing observed in the following appointment. After 3 years of follow-up, the patient is recovered, with no clinical signs or symptoms of the disease.

<p>Diversas doenças sistêmicas e seus tratamentos podem predispor ao desenvolvimento de cáries dentárias agressivas. A radioterapia de cabeça e pescoço, quimioterapia, síndrome de Sjögren e tratamentos prolongados com as drogas que induzem a hipossalivação são algumas destas condições. O objetivo deste artigo é descrever as características clínicas de cinco pacientes que desenvolveram doença do enxerto contra hospedeiro crônica (DECHc) como uma complicação do transplante alogênico de células-tronco hematopoiéticas (aloTCTH) e, apesar do acompanhamento periódico com dentistas, desenvolveram cáries rampantes. Nestes casos relatados, as restaurações mostraram falhas precoces e as cáries continuaram progredindo até a destruição generalizada dos dentes. A maioria dos dentes, portanto, foi extraída devido à cárie avançada e rápida progressão clínica. Neste artigo, o termo "cáries relacionadas à DECHc" é proposto para descrever esta complicação pouco conhecida do tratamento do câncer, que se manifesta em receptores de TCTH que desenvolvem DECHc. Esta condição é pouco reconhecida na literatura e pode representar o resultado final do agrupamento das complicações bucais em pacientes com DECHc, incluindo mucosite, dor oral, hipossalivação, perda de paladar e infecções orais, levando à cárie rampante devido à dificuldade de higiene oral e aumento da ingestão de alimentos altamente cariogênicos. Por consequência, o conhecimento desta complicação oral deve melhorar os tratamentos médico e odontológico das manifestações bucais da DECHc e melhorar a qualidade de vida dos pacientes com esta complicação após o TCTH.</p>

<p>Several systemic diseases and their medical treatment may predispose the development of aggressive dental caries. Head and neck radiotherapy, chemotherapy, Sjögren's syndrome and long-standing treatment with drugs that induce hyposalivation are some of these conditions. The aim of this article is to describe the clinical features of five patients who developed chronic graft-versus-host-disease (cGVHD) as a complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and, in spite of close dental follow-up, subsequently developed rampant caries. In these cases, the restorations showed early failure and the caries still progressed until generalized teeth destruction. The majority of the teeth therefore had to be extracted due to advanced dental caries and rapid clinical progression. Herein the term "cGVHD-related caries" is proposed to describe this under-recognized complication of cancer treatment that may evolve in allo-HSCT recipients that develop cGVHD. This condition is poorly recognized in the literature and may represent the final result of the clustering of oral complications in cGVHD patients, including mucositis, oral pain, hyposalivation, taste loss and oral infections, leading to rampant caries due to impaired oral hygiene and increased intake of highly cariogenic food. Consequently, the knowledge of this oral complication should improve the medical and dental management of cGVHD oral manifestations and improve the quality of life of patients with this post allo-HSCT complication.</p>

O granuloma central de células gigantes (GCCG) é uma lesão benigna dos maxilares predominantemente encontrada na mandíbula de pacientes jovens do sexo feminino com um variado comportamento clínico. Apesar de o manejo cirúrgico representar a principal modalidade terapêutica para esta lesão, o uso de injeções intralesionais de esteróides tem sido recentemente proposto para seu tratamento. Além do manejo conservador, o uso da punção aspirativa por agulha fina (PAAF) para o diagnóstico do GCCG tem sido comprovado ser uma abordagem segura e eficiente, especialmente útil em casos de lesões localizadas em regiões estéticas. Descrevemos aqui um caso de GCCG estendendo-se para a gengiva adjacente em um paciente do sexo masculino, 15 anos de idade, diagnosticado por meio da PAAF e subsequentemente tratado com injeções intralesionais de uma solução de acetato de triancinolona e oleato de etanolamina que levou a uma importante remissão clínica, permitindo a realização de uma abordagem cirúrgica conservadora preservando a estética periodontal. Por este motivo, ambos os procedimentos podem ser considerados opções de manejo para o GCCG dos maxilares.

Central giant cell granuloma (CGCG) is a benign jaw lesion predominantly found in the mandible of young female patients with a variable clinical behavior. Although surgical management is regarded as the main treatment modality for this lesion, the use of intralesional injections of steroids has been recently advocated for its treatment. In addition to this conservative management, the use of fine needle aspiration cytology (FNAC) for diagnosing CGCGs has been proven a safe and efficient approach, especially useful in cases with lesions located in esthetic regions. Herein, it is described a case of CGCG extending to the overlying gingiva of a 15-year-old male patient diagnosed by FNAC and subsequently treated with intralesional injections of a solution of triamcinolone acetonide and ethanolamine oleate that led to an important clinical remission, allowing a more conservative surgical procedure for preservation of gingival esthetics. Therefore, both procedures can be considered as management options for CGCG of the jaws.

The objective of this review is to present pre-radiotherapy evaluation criteria and the main needs for treatment of these patients after the radiation therapy. Were revised articles in English, Spanish and Portuguese language between 1995 and 2009 indexed in Pubmed and Scielo. The keywords were oral cancer and radiotherapy, complications in head and neck radiotherapy, oral pre-radiotherapy evaluation.The adverse complications of radiotherapy in head and neck area could be temporary or late. The late effects, such as radiation caries and osteorradionecrosis could be directly associated with the fact that previous dental evaluation was not performed and can severely affect the post-operatory quality of life. The participation of the dentist in the multidisciplinary team and dental evaluation of the patients that will receive radiotherapy in the head and neck area are of vital importance to improve the post-operatory quality of life of these patients.

El objetivo de esta revisión es presentar criterios de evaluación odontológica pre-radioterapia y cuáles son las principales necesidades de tratamiento de estos pacientes después del tratamiento de radiación. Fueron revisados artículos en inglés, español y portugués entre 1995 y 2009 indexados en Pubmed y Scielo. Las palabras claves fueron: cáncer oral y radioterapia, complicaciones de la radioterapia en cabeza y cuello, evaluación oral pre-radioterapia.Los efectos colaterales de la radioterapia en la región de cabeza y cuello pueden ser temporales o tardíos. Aquellos que son tardíos, como la caries de radiación y la osteorradionecrosis pueden estar directamente relacionados con el hecho de no haber realizado una evaluación odontológica previa y pueden afectar severamente la calidad de vida del paciente.La participación del cirujano-dentista en el equipo multidisciplinario y la evaluación odontológica de los pacientes que serán sometidos a radioterapia en la región de cabeza y cuello son de vital importancia en mejorar la calidad de vida post-operatoria de estos pacientes.
