ABSTRACT

Abstract The aim of this study was to evaluate the time elapsed from first symptoms to the treatment of oral and oropharyngeal cancer (OOC) and to identify variables associated with treatment delay. This is an observational study with retrospective and prospective data collection. Patients with a diagnosis of OOC seen at the Head and Neck Surgery outpatient clinic of a Brazilian public hospital were included and followed up to treatment initiation. Participants answered a questionnaire for the collection of socioeconomic, demographic, cultural, and clinical information, as well as information about the time elapsed from first symptoms to the first appointment with a head and neck surgeon. Time to treatment was classified into four intervals: 1- first symptoms to first medical appointment; 2- first medical appointment to specialized medical care; 3- specialized medical care to preparation for treatment; and 4- preparation for treatment to treatment initiation. Bivariate statistics were computed. Out of 100 participants, nine died before treatment. Mean time to treatment was 217 days. Highest mean time was observed for interval 2 (94 days), followed by interval 1 (63 days), interval 4 (39 days), and interval 3 (21 days). At interval 1, a longer time was associated with severe alcohol consumption, severe smoking, and family history of cancer. At interval 2, the delay was associated with appointment with a general practitioner, clinical diagnosis of disease other than cancer, and antibiotic prescription. At interval 4, delay in treatment was associated with surgical treatment. Patients with OOC experience delays from symptom onset to treatment initiation. The longest interval was associated with professional delay, followed by patient delay in help-seeking.

ABSTRACT

Abstract About 92,000 new cases of oropharynx carcinoma are expected to occur annually worldwide. There is no consensus about the best therapy for these advanced tumors. The objective of the present study was to evaluate overall and disease-free survival rates of patients with advanced oropharynx squamous cell carcinoma, comparing surgery + radiotherapy with chemotherapy + radiotherapy. Medical records of patients were reviewed. Previously treated tumors were excluded. Clinical, demographic and microscopic information was collected, and p16 staining was performed. Kaplan-Meier survival curves were plotted. Forty-seven cases were included, 41 men and 6 women, having a mean age of 56.3 years. Most patients were smokers (85.1%) and consumed alcohol (74.5%). Patients were stage III (21.3%) or IV (78.7%). Most lesions affected the base of the tongue (36.2%). Of the 23 cases available for p16 testing, 3 were positive (13.0%). There was no difference between the overall and the disease-free survival rates for the two treatment modalities (p>0.05), even when only resectable tumors were compared. Seventeen cases experienced recurrence (36.2%); 16 (34.0%) patients remained alive without disease; 15 (31.9%) died due to disease; 9 (19.2%) were recurrent at the last follow-up. The two treatment protocols were equally efficient in treating advanced oropharynx squamous cell carcinoma, since both promoted similar overall and disease-free survival rates. The results and interpretations related herein mostly regard "conventional" oropharyngeal squamous cell carcinomas, as opposed to HPV-associated tumors.

ABSTRACT

ABSTRACT Introduction: Hemophilia is a coagulopathy caused by a deficiency in coagulation factors VIII (hemophilia A) or IX (hemophilia B). It is a chronic disease and, hence, impairs the quality of life (Qol) of the patients. This study aimed to evaluate the Qol of patients with hemophilia using the WHOQOL-bref and the Haemo-A-Qol instruments, its relation to the clinical condition and its sociodemographic variables. Methods: This is a cross-sectional, epidemiological study, comprising 17 patients with hemophilia, registered at the hemocenter, who met the eligibility criteria. Data were collected using three questionnaires: a semi-structured clinical evaluation form, the WHOQOL-bref and the Haem-A-Qol. Results: The average age was 30 years old, and most participants declared themselves to be single (58.82%), without children (64.70%) and employed (58.82%). Hemophilia A was observed in 14 patients and the most severe form of the disease was more prevalent (64.70%). The average score of Qol, estimated by the WHOQOL-bref questionnaire was 74.3; being "social relations" the domain with the highest average. The Haem-A-Qol measured an average of 36.2 and the domain with the highest result was "Family Planning". Conclusion: Hemophilia had a higher negative impact upon the physical, sports and leisure features in the sample subjects. The analysis of the questionnaires did not reveal statistical agreement between them. Based on this, the Haem-A-Qol is considered the most recommended to evaluate the Qol, as it addresses factors more specifically related to the disease. No statistical significance was observed between the scores of Qol, as for the presence of comorbidities, gravity of the hemophilia and positive serology for infections.

ABSTRACT

O lipossarcoma de laringe é uma neoplasia extremamente rara, acomete principalmente o sexo masculino, principalmente na quinta década de vida. Existindo apenas cerca de 40 casos descritos na literatura, desses nenhum em língua portuguesa. O presente caso relata o diagnóstico em um paciente do sexo masculino, 57 anos, ex-tabagista, apresentando alteração de voz e obstrução de via área. Foi optado por ressecção cirúrgica completa com achados sugestivos de lipossarcoma bem diferenciado. Foi optado por manter seguimento, não tendo sido indicado quimioterapia e radioterapia adjuvantes.(AU)


Laryngeal liposarcoma is an extremely rare neoplasm that affects especially men in the fifth decade of life. There are only about 40 cases described in the literature, none of them in the Portuguese language. We report the case of a 57-year-old, former smoker man presenting with voice disorders and airway obstruction. We opted for complete surgical resection with findings suggestive of well-differentiated liposarcoma. We chose to keep following the patient, and no adjuvant chemotherapy and radiotherapy were indicated. (AU)

ABSTRACT

No Brasil, registros hospitalares de câncer revelam a boca como a oitava localização mais frequente de tumores malignos, sendo a maioria delas diagnosticada em estádio avançado. Em países desenvolvidos, as taxas de diagnóstico tardio são cerca de 40%. O diagnóstico e tratamento precoces representam mais chance de cura, baixo custo emenos morbidade. Este artigo objetiva verificar as possíveis razões de atraso no diagnóstico e tratamento das neoplasias bucais e refletir sobre os seus motivos. Os termos neoplasias bucais, diagnóstico, epidemiologia e terapia foram introduzidos nas bases de dados MEDLINE, LILACS e SCIELO. Foram analisados 31 estudos, entre 1995 e 2011,que discorriam sobre o atraso diagnóstico em relação ao paciente, ao profissional e ao sistema de saúde. Observou-se que o atraso diagnóstico associou-se a: a) pacientes: solteiros, etilistas e com medo do diagnóstico; b) médico: pouco conhecimento sobre o assunto e alta carga de trabalho; c) sistema de saúde: filas para atendimento médico, distância de unidades de saúde e centros de referência da moradia do paciente e experiênciasnegativas no serviço de saúde. É fundamental entender as possíveis causas de atraso e limitações dos serviços de saúde e de seus profissionais para que medidas adequadas sejam tomadas individual e coletivamente para propiciar diagnóstico e tratamento precoce aos pacientes.


In Brazil, hospital cancer records reveal the mouth as the eighth most frequent location of malignant tumors, most of them being diagnosed at advanced stages. In developed countries, diagnosis of late rates is about 40%. Early diagnosis and treatment represent increased chances of a cure, low cost, and less morbidity. This article aims to assess thepossible reasons for delays in the diagnosis and treatment of oral cancer and reflects on the reasons. The terms mouth neoplasias, diagnosis, epidemiology, and therapy were introduced in the MEDLINE, LILACS, and SciELO databases. A total of 31 studies published between 1995 and 2011 were analyzed, which discoursed about the delayed diagnosis in relation to patients, professionals, and healthcare systems. It was observedthat the diagnostic delay was associated with: a) patients: single, alcoholic, and afraid of the diagnosis; b) Professionals: little knowledge on the subject and high workload; c) healthcare systems: queues for medical care, distance between the patient?s residence and healthcare units and reference centers, and negative experiences in the healthcareservice. It is critical to understand the possible causes of delay and limitations of healthcare services and its professionals for appropriate actions to take place individually and collectively providing early diagnosis and treatment to these patients.

ABSTRACT

The Actinomyces sp has been linked to osteoradionecrosis of the jaw. The identification of these bacteria on histopathological findings confers a determining factor of poor prognosis and is related to difficulties of local control of bone necrosis and risk of recurrent infections. The treatment is complicated due to insidious growth pattern of Actinomyces sp. The methods for diagnosis and therapeutic approaches constitute challenges that underscore the need for understanding the risk factors for infection and knowledge about clinical conditions associated with this pathology. The objective of this study is to report two cases of cancer patients suffering from an osteoradionecrosis infection by Actinomyces sp, to describe approaches and discuss therapeutic options in the light of the current literature.


O Actinomyces sp tem sido associado a osteorradionecrose. A identificação desta bactéria confere um fator determinante de mau prognóstico e está relacionado a dificuldades do controle da necrose óssea local e a risco de infecções recorrentes. O tratamento é complicado devido ao padrão de crescimento insidioso do Actinomyces sp. Os métodos de diagnóstico e as abordagens terapêuticas constituem desafios que reforçam a necessidade de compreender os fatores de risco para a infecção e o conhecimento sobre as condições clínicas associadas a esta patologia. O objetivo deste trabalho é relatar dois casos clínicos de pacientes com câncer que sofrem infecção osteorradionecrose por Actinomyces sp, para descrever as abordagens e discutir as opções terapêuticas à luz da literatura atual.

ABSTRACT

O câncer de boca representa um problema de saúde pública devido aos diagnósticos tardios e das taxas de morbimortalidade. Esse estudo avaliou o nível de conhecimento dos odontólogos (23) da atenção primária da rede pública de Divinópolis (MG) sobre o câncer bucal. Empregou-se questionário estruturado e os dados obtidos demonstraram que 39,1% dos entrevistados não sabiam qual o tipo mais comum de câncer de boca; 35% avaliaram seu nível de conhecimento como bom ou ótimo. Fatores de risco apontados: uso do tabaco, antecedentes familiares, uso do álcool e exposição solar. Apenas 13% receberam treinamento para o exame de câncer bucal na graduação. Esses achados reforçam a necessidade de abordagem do tema no período de formação acadêmica e de educação continuada.


Oral cancer represents a major public health problem due to high rates of late diagnoses and significant morbidity and mortality rates. This study assessed the level of knowledge of active dentists (23) in primary care in public health at Divinópolis (MG) on oral cancer. A structured questionnaire was used. The data showed that 39.1% of respondents didn`t know what the most common type of oral cancer, 35% rated their level of knowledge as good or great. Tobacco use, family history, alcohol use and sun exposure were the most likely risk factors mentioned. Only 13% received training for oral cancer exam on graduation. These findings reinforce the need for a greater approach regarding the theme during academic training and continuing education.

ABSTRACT

Introdução: O carcinoma de células escamosas (CCE) de laringe, em nosso meio, é frequentemente diagnosticado em estadios avançados, encontrando-se metástases cervicais em até 50,0% dos pacientes. Considerando que a presença de metástases é importante fator na definição de proposta terapêutica e prognóstico, é da maior importância o estudo de métodos diagnósticos que permitam com segurança o estadiamento de metástases cervicais no pré- e per operatório. Objetivo: Avaliar a acurácia do exame clínico, em relação ao estadiamento das metástases cervicais, comparando-o ao estadiamento anatomopatológico em pacientes submetidos ao tratamento cirúrgico do CCE de laringe. Métodos: Foram avaliados 89 pacientes, com diagnóstico de CCE de laringe, submetidos à laringectomia total e esvaziamento cervical, entre os anos de 2009 e 2012. Comparamos o estadiamento cervical clínico (N) com o estadiamento patológico. Resultados: Foram encontradas metástases cervicais ao exame anatomopatológico em 55 dos 89 pacientes estudados (61,7%), sendo que em oito deles (8,9%) não foram detectados ao exame clínico. Em 18 pacientes (20,2%) o estadiamento anatomopatológico apontou doença mais avançada que o estadiamento clínico, que por sua vez apresentou sensibilidade de 76,0% e especificidade de 87,0%, sendo seu valor preditivo positivo de 89,5% e o valor preditivo negativo de 62,0%. Conclusão: O estadiamento clínico apresenta acurácia, valor preditivo positivo e especificidade para detectar metástases cervicais no CCE de laringe inferior, mas ainda assim comparáveis, aos métodos de imagem sendo a tomografia computadorizada cervical a principal delas. Entretanto, apresenta acurácia menor que o estadiamento anatomopatológico principalmente em pacientes submetidos a traqueostomia previamente ao exame clínico e cirurgia, e portanto, não deve ser o único norteador da proposta terapêutica.


Introduction: The laryngeal squamous cell carcinoma (SCC) is often diagnosed in advanced stages and hidden cervical metastasis are found in until 50% of the patients. As one of the most important factors related to its prognosis, cervical metastasis have been studied recently as well as the diagnostic methods related to their staging. Objective: This study aims to estimate the accuracy of the clinical findings to stage cervical metastasis in patients with laryngeal SCC in comparison to the histopathological staging. Methods: The survey included 89 patients diagnosed with laryngeal SCC, who were submitted to total laryngectomy and cervical lymph node dissection from 2009 until 2012. Their clinical cervical staging before surgery were compared to the histological staging as well as the factors which may be related to the different results between them. Results: In 55 of the 88 patients (61,7%), there were found cervical metastasis in the histological exam, in which 8 of them (8,9%) the clinical examination had not found metastasis. In 18 patients (20,2%), the hystopathological staging presented a more advanced stage then the one showed by the clinical examination. The sensibility of the clinical examination was 76,0% and the specificity, 87%. The positive predictive value was 89,5% and the negative predictive value was 62%. Conclusion: The clinical staging presents lower accuracy, positive predictive value and specificity than others diagnostic methods such as the Cervical Computed Tomography, but still comparable to them, what makes it important to the cervical metastasis staging. Although, due to its low accuracy if compared to the hystopathological staging mainly in patients submitted to tracheostomy before clinical exam and surgery, it cannot be the only leading factor to be considered to define treatment.

ABSTRACT

Introdução: O retalho miocutâneo infrahioideo (RMI) foi descrito por Wang em 1986. É utilizado em Cirurgia de Cabeça e Pescoço para reconstrução após ressecção de tumores, com sua principal indicação em tumores de andar inferior de boca. Objetivo: Avaliar, de forma retrospectiva, a exequibilidade e confiabilidade do RMI. Método: RMI foi utilizado na reconstrução cirúrgica em 25 pacientes portadores de carcinoma de andar inferior de boca. Apenas um dos cirurgiões do grupo tinha experiência prévia com a técnica. Os demais realizaram um único procedimento sob supervisão, a partir do qual os realizavam de forma independente. Resultados: Em três casos (12,0%) houve deiscência de sutura entre o retalho e o leito receptor, formação de fístula salivar e consequente deiscência de sutura no sítio doador. Em quatro pacientes (16,0%) houve epidermólise, com descamação e posterior reepitelização, sem necessidade de reintervenção cirúrgica.a Em dois pacientes (8,0%), houve necrose total da pele no terço distal do retalho, tratada com debridamento local. Não houve necrose muscular do RMI e não ocorreram complicações tardias. Comparando-se os três cirurgiões, não se observou diferenças nas taxas de complicações. Conclusão: O RMI é exequível no nosso meio, pois não demanda material específico e tem rápida curva de aprendizado. Os cirurgiões com vivência na especialidade podem facilmente incorporar essa técnica em sua rotina de reconstrução. As taxas de complicações são aceitáveis. O RMI é útil para reconstrução em cirurgia de cabeça e pescoço, notadamente para tumores iniciais de assoalho de boca e língua oral.


Introduction: The musculocutaneous infrahyoid flap (MIF) was described by Wang in 1986. It is used in reconstruction on head and neck surgery, with its main indication in tumors of the mouth floor. Objective: Evaluate retrospectively, the feasibility and reliability of the MIF. Method: The MIF was used in the surgical reconstruction in 25 patients with squamous cell carcinoma of the buccal floor. Only one surgeon of the group had prior experience with the technique. The other two surgeons performed the first procedure under supervision, then they performed independently. Results: Three cases (12.0%) had dehiscence between the flap and the recipient site, salivary fistula formation and subsequent wound dehiscence at the donor site. Four patients (16.0%) had epidermolysis with flaking and subsequent re-epithelialization without need for surgical intervention. In two patients (8.0%), there was complete necrosis of the distal skin flap treated with debridement site. There was no muscle necrosis of MIF and there were no late complications. Comparing the three surgeons , no differences in complication rates was observed. Conclusion: MIF is feasible in our country because it does not require special equipment and has fast learning curve . Surgeons with experience in the art can easily incorporate this technique into your routine reconstruction. Complication rates are acceptable. The MIF is useful for reconstruction of head and neck surgery, especially for tumors initial floor of the mouth and oral tongue.

ABSTRACT

OBJETIVO: Avaliar a incidência de fístula faringocutânea após laringectomia total e tentar identificar os fatores preditores. MÉTODOS: No período de maio de 2005 a abril de 2010, 93 pacientes foram submetidos à laringectomia total. Foram avaliadas as complicações per e pós-operatórias e comparadas com as seguintes variáveis: sexo, estado nutricional, traqueostomia prévia, localização do tumor primário, tipo de operação realizada, estadiamento de acordo com o TNM, tratamento prévio com quimioterapia e/ou radioterapia, utilização de retalhos para reconstrução e margem cirúrgica. Todos os pacientes apresentavam a neoplasia em estádio avançado segundo o TNM. RESULTADOS: 14 (15,1%) pacientes evoluíram com fístula salivar no pós-operatório. O tempo médio de aparecimento da fístula salivar foi 3,5 dias, com desvio padrão de 13,7 dias. Comparando a fístula salivar com as variáveis TNM, tipo de operação e esvaziamento cervical, traqueostomia prévia, utilização de retalho miocutâneo, rádio e quimioterapia pré-operatória e margem cirúrgica, não foi observado diferença estatisticamente significativa (p>0,05). CONCLUSÃO: A incidência de fístula salivar foi 15,1% e não foi encontrado fator preditor para sua formação.


OBJECTIVE: To evaluate the incidence of pharyngocutaneous fistula after total laryngectomy and try to identify its predictors. METHODS: From May 2005 to April 2010, 93 patients underwent total laryngectomy. We evaluated complications during and after surgery and compared them with the following variables: gender, nutritional status, previous tracheotomy, tumor location, type of surgery, TNM staging, prior treatment with chemotherapy and/or radiotherapy, use of flaps for reconstruction and surgical margin. All patients presented with advanced neoplastic disease according to TNM. RESULTS: 14 (15.1%) patients developed postoperative salivary fistula. The mean time to onset of salivary fistula was 3.5 days, with a standard deviation of 13.7 days. Comparing salivary fistula with TNM variables, type of operation and neck dissection, prior tracheotomy, use of flap, preoperative radio and chemotherapy and surgical margin, there was no statistically significant difference (p> 0,05). CONCLUSION: The incidence of salivary fistula was 15.1% and no predictive factor for its formation was found.

ABSTRACT

OBJETIVO: Avaliar a incidência e os fatores preditores da hipocalcemia e hipoparatireodismo definitivo pós-tireoidectomia. MÉTODOS: Foi dosado cálcio iônico no pré e no pós-operatório (primeiro, segundo e 30ºdia) em 333 pacientes submetidos à tireoidectomia. Naqueles que apresentaram hipocalcemia, as dosagens foram feitas também aos 90 e 180 dias de pós-operatório, quando se dosou também o paratormônio. Os pacientes foram agrupados segundo a presença ou ausência de hipocalcemia e avaliados segundo idade, sexo, função tireoidiana, volume tireoidiano, número de paratireoides identificadas e necessidade de reimplante de paratireoides, tipo de operação, tempo operatório e diagnóstico histopatológico. RESULTADOS: A incidência de hipocalcemia temporária foi de 40,8% (136 pacientes), e hipoparatireoidismo definitivo de 4,2% (14 pacientes). Tireoidectomia total ou reoperação, esvaziamento cervical, hipertireoidismo, tempo operatório e idade acima de 50 anos foram fatores determinantes de incidência significativamente maior de hipocalcemia e hipoparatireodismo definitivo (p<0,05). CONCLUSÃO: os fatores preditores da hipocalcemia pós-operatória incluem idade (>50 anos), tireoidectomia total, reoperação, esvaziamento cervical e tempo operatório. Os fatores preditores do hipoparatireoidismo definitivo pós-tireoidectomia incluíram tipo de operação, diagnóstico histológico e hipertireoidismo.


OBJECTIVE: To evaluate the incidence and predictors of post-thyroidectomy definitive hypocalcemia and hypoparathyroidism. METHODS: We assessed ionic calcium preoperatively and postoperatively (first, second and 30th day) in 333 patients undergoing thyroidectomy. In those presenting hypocalcemia, measurements were also made 90 and 180 days after surgery, when parathormone was also dosed. Patients were grouped according to the presence or absence of hypocalcemia and evaluated according to age, gender, thyroid function, thyroid volume, number of parathyroid glands identified and need to parathyroid reimplantation, type of operation, operative time, and histopathological diagnosis. RESULTS: The incidence of temporary hypocalcemia was 40.8% (136 patients), and of definitive hypoparathyroidism 4.2% (14 patients). Reoperation or total thyroidectomy, neck dissection, hyperthyroidism, operative time and age above 50 years were factors related to higher incidence of hypocalcemia and definitive hypoparathyroidism (p <0.05). CONCLUSION: predictors of postoperative hypocalcemia included age (> 50 years), total thyroidectomy, reoperation, neck dissection and operative time. The predictors of post-thyroidectomy definitive hypoparathyroidism included type of operation, histological diagnosis and hyperthyroidism.

ABSTRACT

Laringectomias de resgate estão associadas a altas taxas de complicações pós-operatórias. O uso de retalhos na reconstrução do trânsito faríngeo poderia reduzir a incidência destas complicações. OBJETIVO: Avaliar a utilidade do retalho miocutâneo de músculo peitoral maior na prevenção da fístula salivar no pós-operatório de laringectomia total de resgate. MÉTODO: Estudo retrospectivo, realizado de abril/2006 a maio/2011, com 31 pacientes portadores de CCE de laringe recidivado, tratados previamente com quimiorradioterapia ou radioterapia isolada, submetidos à laringectomia de resgate. Destes 31 pacientes, a reconstrução da faringe foi realizada com utilização do retalho miocutâneo de músculo peitoral maior em 19 (61%) casos, enquanto o fechamento primário ocorreu em 12 pacientes (39%). RESULTADOS: Foi observada taxa de fistula salivar em (16%) dos pacientes em que se utilizou o retalho e 58% nos pacientes submetidos a fechamento primário da faringe (p < 0,02). Não foi observada diferença estatisticamente significativa entre os grupos em relação ao tempo médio de aparecimento de fistula e reintrodução da dieta por via oral, bem como tempo de uso de cateter nasoentérico para alimentação. CONCLUSÃO: O retalho miocutâneo do músculo peitoral maior mostrou-se como opção capaz de reduzir incidência de fistula salivar em laringectomias de resgate.


Salvage laryngectomy in patients treated with organ preservation protocols is associated with high rates of postoperative complications. The use of non-irradiated tissue flaps in pharyngeal reconstruction could reduce the incidence of these complications. OBJECTIVE: This study aims to evaluate the usefulness of the pectoralis major myocutaneous flap in preventing salivary fistulae during the postoperative period of salvage total laryngectomy (TL). MATERIALS AND METHOD: This retrospective study enrolled 31 patients operated between April of 2006 and May of 2011. All patients had advanced cancer at the time of the salvage procedure and had been treated with chemoradiotherapy or radiotherapy alone. Pharyngeal reconstruction was performed using pectoralis major myocutaneous flap in 19 cases (61%); primary wound closure occurred in 12 patients (39%). RESULTS: Salivary fistulae occurred in 16% of the patients who received the flap and in 58% of the patients with primary closure of the pharynx (p < 0.02). No statistically significant differences were noted between the groups with respect to the mean time for fistula formation, reintroduction of an oral diet, or use of a nasoenteric tube for feeding. CONCLUSION: The pectoralis major myocutaneous flap was found to reduce the incidence of salivary fistulae in salvage laryngectomy procedures.

ABSTRACT

O presente relato de caso refere-se ao carcinomaneuroendócrino de pequenas células de laringe acometendouma mulher de 52 anos. Este carcinoma é umaneoplasia altamente maligna com metástases frequentese taxa de sobrevida baixa. Depois dos carcinomasespinocelulares, os tumores de laringe mais frequentessão os neuroendócrinos, que podem ser derivados decélulas neurais ou epiteliais. Os tumores neuroendócrinosderivados de epitélio podem ser classificados emquatro grupos patológicos bem definidos: tumor carcinoide,tumor carcinoide atípico, carcinoma neuroendócrinode pequenas células e carcinoma neuroendócrinode células grandes. Os carcinomas neuroendócrinos têmmorfologia distinta, entretanto apresentam perfil imunohistoquímicomarcado por algumas combinações depositividade para citoqueratina, cromogranina, sinaptofisina,CD56, CD57, enolase, serotonina, somatostatinae bombesina.

This case report refers to small cell neuroendocrinecarcinoma of the larynx affecting a 52-year-old female.This is a highly malignant neoplasm with frequentmetastases and a lower survival rate. After squamouscarcinomas, the most frequent tumors of the larynx arethe neuroendocrine, these tumors can be derived fromneural or epithelial cells. Neuroendocrine tumors derivedfrom epithelium can be classified into four pathologicalcategories defined: carcinoid tumor, atypical carcinoidtumor, small cell neuroendocrine carcinoma andlarge cell neuroendocrine carcinoma. It is known thatdespite of having distinct morphology, neuroendocrinecarcinomas have immunohistochemical profile markedby some combination of positive for cytokeratin, chromogranin,synaptophysin, CD56, CD57, enolase, serotonin,somatostatin and bombesin. These laryngeal tumorsshow a broad spectrum of clinical, dependent onthe histological subtype, which influences the planningof the whole treatment.

ABSTRACT

O linfoepitelioma de glândulas salivares maiores é um tumor maligno e raro, principalmente no ocidente. No presente artigo, descrevemos o caso de uma paciente do sexo feminino, com linfoepitelioma de parótida, que recidivou precocemente depois de cirurgia isolada e alcançou remissão depois de quimiorradiação. A paciente encontra-se no 19º mês de seguimento clínico, sem sinais de recidiva ou sequelas do tratamento. A literatura pertinente ao assunto foi revisada.


Lymphoepithelioma of major salivary glands is a rare malignant tumor, affecting mainly the population of Western countries. In the present paper, we report the case of a female patient with parotid lymphoepithelioma, which recurred early after surgery. The patient achieved remission after chemoradiation and has been followed up for 19 months with no evidence of relapse and sequelae of treatment. Additionally, we reviewed the relevant literature related to this topic.

ABSTRACT

O câncer de hipofaringe representa 5 a 10% das neoplasiasdas vias aerodigestivas superiores e frequentemente édiagnosticado em sua forma avançada, com invasão da laringee metástases cervicais. A série é constituída por três pacientesportadores de tumores avançados de hipofaringe com invasãolaríngea. O tratamento cirúrgico, em todos os casos, consistiuem faringolaringectomia circular. A reconstrução foi realizadaconforme a técnica de Fabian modificada por Spriano. Em todosos pacientes ocorreu restabelecimento satisfatório da alimentaçãopor via oral. As técnicas de reconstrução consideradas comopadrão-ouro são o retalho livre vascularizado de alça de jejuno e atransposição gástrica. Uma alternativa às técnicas apresentadasseria a reconstrução com retalho miocutâneo peitoral.


Hypopharyngeal carcinomas of hipofaringe represent 5 to10% of upper aerodigestive tract and is often diagnosed in itsadvanced form, with invasion of the larynx and neck metastases.The series is constituted by three patients with advancedhypopharyngeal tumors. The surgical treatment of all the casesconsisted of total pharyngolaryngectomy. The reconstruction wascarried in agreement with the technique of Fabian modified forSpriano. In all the patients occurred satisfactory reestablishmentof the oral feeding. The considered gold standard techniquesof reconstruction are free jejune interposition and the gastrictransposition. An alternative to the presented techniques would bereconstructions using major pectoralis myocutaneous flap.

ABSTRACT

CONTEXT: Kikuchi-Fujimoto disease (KFD) manifests in most cases as unilateral cervical lymphadenomegaly, with or without accompanying fever. The disease mainly affects young women and has a self-limited course. It is more common in oriental countries, with few reports of its occurrence in Brazil. KFD should be included in the differential diagnosis of suspected cases of viral infections, tuberculosis, reactive lymphadenitis, systemic lupus erythematosus and metastatic diseases. It can be histologically confused with lymphoma. The disease is benign and self-limiting and an excisional biopsy of an affected lymph node is necessary for diagnosis. There is no specific therapy. CASE REPORTS: This study reports on three cases of non-Asian female patients with KFD who were attended at our service between 2003 and 2006. A review of the literature was carried out, with a systematic search on this topic, with the aim of informing physicians about this entity that is manifested by cervical masses and fever.


CONTEXTO: A doença de Kikuchi-Fujimoto (DKF) se manifesta na maioria das vezes como linfadenomegalia cervical unilateral, que pode ser acompanhada de febre. Afeta principalmente mulheres jovens, com evolução autolimitada. A prevalência desta doença é mais comum no oriente, havendo poucos relatos de sua ocorrência em nosso meio. DKF deve ser incluída no diagnóstico diferencial de casos suspeitos de infecções por vírus, tuberculose, linfadenite reacional, lúpus eritematoso sistêmico e doença metastática. Histologicamente pode ser confundida com linfoma. A doença é de caráter benigno, auto-limitada, a biópsia excisional do linfonodo acometido é necessária para o diagnóstico e não há tratamento específico. RELATO DE CASOS: Este trabalho relata três casos de pacientes não asiáticas do sexo feminino com DKF, atendidas em nosso serviço entre 2003 e 2006, e faz revisão da literatura com uma busca sistematizada sobre o assunto, com o objetivo de informar os médicos sobre essa entidade que se manifesta com massa cervical e febre.

ABSTRACT

CONTEXT AND OBJECTIVE: Magnesium ion concentration is directly related and phosphorus ion concentration is inversely related to calcemia. The aim of this study was to evaluate the evolution of magnesium and phosphorus ion levels in patients undergoing thyroidectomy and correlate these with changes to calcium concentration. DESIGN AND SETTING: Prospective study at the Alpha Institute of Gastroenterology, Hospital das Clínicas, Universidade Federal de Minas Gerais. METHODS: The study included 333 patients, of both genders and mean age 45 ± 15 years, who underwent thyroidectomy between 2000 and 2005. Total calcium, phosphorus and magnesium were measured in the blood preoperatively and 24 and 48 hours postoperatively. Ionic changes were evaluated according to the presence or absence of postoperative hypocalcemia. RESULTS: There were statistically significant drops in blood phosphorus levels 24 and 48 hours after thyroidectomy, compared with preoperative values, in the patients without hypocalcemia. In the patients who developed hypocalcemia, there was a significant drop in plasma phosphorus on the first postoperative day and an increase (also statistically significant) on the second day, in relation to preoperative phosphorus levels. A significant drop in postoperative magnesium was also observed on the first and second days after thyroidectomy in the patients with hypocalcemia, in relation to preoperative levels. In the patients without hypocalcemia, the drop in magnesium was significant on the first day, but there was no difference on the second day. CONCLUSION: Despite the postoperative changes, neither magnesium nor phosphorus ion levels had any role in post-thyroidectomy calcemia.


CONTEXTO E OBJETIVO: A concentração do íon magnésio está diretamente e a do íon fósforo inversamente relacionada à calcemia. O objetivo foi avaliar a evolução das concentrações dos íons magnésio e fósforo nos pacientes submetidos a tireoidectomia, e relacioná-los com as alterações da concentração do cálcio. TIPO DE ESTUDO E LOCAL: Estudo prospectivo realizado no Instituto Alfa de Gastroenterologia, Hospital das Clínicas, Universidade Federal de Minas Gerais. MÉTODOS: O estudo incluiu 333 pacientes de ambos os sexos, com média de idade de 45 ± 15 anos, submetidos a tireoidectomia no período de 2000 a 2005. Cálcio total, fósforo e magnésio foram dosados no pré-operatório e com 24 e 48 horas de pós-operatório. As alterações dos íons foram avaliadas de acordo com a presença ou ausência de hipocalcemia pós-operatória. RESULTADOS: Houve queda estatisticamente significativa dos níveis sanguíneos de fósforo 24 horas e 48 horas após a tireoidectomia em relação ao pré-operatório nos pacientes que não tiveram hipocalcemia. Quanto aos pacientes que evoluíram com hipocalcemia, houve queda significativa do fósforo plasmático no primeiro dia de pós-operatório e elevação, também estatisticamente significativa, no segundo dia em relação ao fósforo pré-operatório. Foi também observada queda significativa do magnésio pós-operatório em relação ao pré-operatório no primeiro e no segundo dia após a tireoidectomia nos pacientes com hipocalcemia. Naqueles sem hipocalcemia, a queda do magnésio foi significativa no primeiro dia, mas não houve diferença no segundo dia. CONCLUSÃO: Embora alterados no pós-operatório, as concentrações dos íons magnésio e fósforo não apresentaram papel na calcemia pós-tireoidectomia.

ABSTRACT

CONTEXT: The minimal recommended surgical approach to parotid tumors is partial parotidectomy with resection of the superficial lobe of the gland. Histologic diagnosis prior to surgery is not possible, as incisional biopsies are contraindicated due to the possibility of facial nerve injury or incomplete tumor resection. Thus, the biopsies tend to be perioperative. OBJECTIVE: To compare the results of frozen section examination with the definitive pathological diagnosis. DESIGN: Accuracy study by retrospective analysis. SETTING: Head and Neck Surgery Service of Heliópolis Hospital, São Paulo, Brazil. SAMPLE: 153 cases of parotid gland tumors treated between 1977 and 1994. DIAGNOSTIC TEST: Frozen section and pathological diagnosis. MAIN MEASUREMENTS: Sensibility and specificity of the frozen section examination. RESULTS: Frozen section study diagnosed 19 (12.4 percent) malignant and 127 (83.7 percent) benign tumors. Sensitivity of the frozen sections for malignancy was 61.5 percent (95 percent CI 54 to 69 percent) and specificity was 98 percent (95 percewnt CI 94 to 100 percent), and this result is comparable to the literature. CONCLUSIONS: We consider that frozen section examination for salivary gland tumors is not sufficient on its own for deciding on the best management. Their interpretation must be correlated with clinical and intraoperative findings, in association with the surgeon's experience

ABSTRACT

O encontro de fatores preditivos de metástase cervical seria de grande valia para o tratamento de pacientes com tumores de alto potencial metastatizante e com pescoço clinicamente negativo. Procuramos encontrar fatores clínicos e histológicos em tumores iniciais de língua e soalho de boca que pudessem indicar a realização de um esvaziamento cervical eletivo. Foram estudados os seguintes fatores: sexo, idade, tabagismo, etilismo, raça, tamanho da lesão, sítio primário, dor, tempo de queixa, primeira queixa, aspecto macroscópico da lesão, infiltrado inflamatório peritumoral, grau de diferenciação da biópsia, desmoplasia, invasão vascular, invasão perineural e número de mitoses por 10 campos de maior aumento...
