ABSTRACT

ABSTRACT Background: The treatment of multiple myeloma (MM) has evolved significantly in the past decade, and new drug combinations have improved the response rates and prolonged survival. Studies comparing different induction chemotherapy regimens have shown that triple combinations have better results than double combinations. However, comparisons among different triple combinations are rare in the literature. Methods: We retrospectively compared two triple combinations comprising bortezomib, cyclophosphamide and dexamethasone (VCD) versus thalidomide, cyclophosphamide and dexamethasone (CTD), and aimed at identifying which of the two combinations would yield better response rates following four induction cycles prior to hematopoietic cell transplantation in patients with untreated multiple myeloma. Results: We retrospectively reviewed the medical records of 311 patients from 24 different centers.The VCD regimen was used as induction therapy by 117 (37.6%) patients, whereas 194 (62.4%) patients received the CTD regimen. After four cycles of induction on an intention-to-treat basis, 54% of the patients in the VCD group achieved at least very good partial response versus 42.8% in the CTD group (p = 0.05). We observed no difference in neuropathy or thrombotic events rates among the two regimens. Conclusion: Our results corroborate the superiority of the triple combination regimes containing bortezomib over the triple combination with thalidomide as pre ASCT induction therapy in MM.

ABSTRACT

ABSTRACT Objective: To describe the oral health status of patients with multiple myeloma and compare to a control group. Materials and methods: The medical history of the studied subjects was obtained from the medical records and through interviews. Trained examiners evaluated the oral mucosa, teeth, periodontium and imaging aspects. The dental status was evaluated by the decayed, missing and filled teeth index. The presence of bone lesions was investigated with cone beam computer tomography images of the jaws. Results: The most common oral mucosa features were paleness (31%) and coated tongue (14.3%) in the multiple myeloma group (N = 42); and coated (21.4%) and fissured tongue (10.7%) in the control group (N = 28). The mean DMFT index of patients with multiple myeloma was high, but not significantly different from controls (14.57 versus 19.69, p = 0.975). Hypodense lesions suggestive of multiple myeloma were observed in the jaws of 73.8% of the patients. Hypodense lesions related to teeth were detected in 33.3% of the patients and in 53.6% of the controls (p = 0.832). Conclusions: The studied population of multiple myeloma patients presented many oral health issues that needed attention. Thus, oral care should be included in the routine treatment to improve the quality of the oral status in these patients.

ABSTRACT

Abstract The range of motion (ROM) may affect the external maximal load during back squat (BS) exercise. The correct ROM manipulation can be useful as an exercise load manipulation strategy, changing the volume load during a resistance training session. The aim of this study was to evaluate the acute effects of ROM on relative load, absolute load and the rating of perceived exertion (RPE) during partial and full BS exercise with adjusted loads. Fifteen male individuals (age: 26.5±4.5 years; height: 173±6 cm; body mass: 80.6 ± 8.8 kg; resistance training experience 5±3 years) participated in this study. The experimental procedure was conducted in two sessions. In the first session, brief familiarization and a 10-repetition maximal test (10-RM) was performed for partial (PBS) and full BS exercise (FBS) with 30-min of rest interval. During the second session, all subjects performed 1 set of 10-RM in both conditions (partial and full ROM), and relative load, absolute load, and RPE were evaluated. A paired t-test was used to compare means. The results showed higher values for PBS when compared to FE exercise: relative load (PBS: 1.14±0.24xBW vs. FBS: 0.87±0.24xBW; P<0.001), and absolute load (PBS: 925±249 kg x FBS: 708±232 kg, P<0.001). Similar RPE was observed between conditions (PBS: 8.6±1.3 IEP x FBS: 8.5±1.0 IEP, P=0.855). It was concluded that PBS allowed higher relative load and absolute load during 10RM, without effects on RPE.


Resumo A amplitude de movimento durante o exercício agachamento pode afetar a sobrecarga imposta ao sistema neuromuscular. Desta forma, a manipulação da amplitude de movimento pode ser utilizada como estratégia de manipulação da sobrecarga do exercício, alterando o volume absoluto da sessão de treinamento bem como os ajustes agudos do sistema neuromuscular. O objetivo do presente estudo foi avaliar os efeitos agudos da amplitude de movimento na sobrecarga relativa, volume absoluto e na percepção subjetiva de esforço (PSE) durante o exercício agachamento total e parcial com sobrecargas ajustadas. Participaram do estudo 15 homens (idade: 26,5±4,5 anos; estatura: 173±6 cm; massa corporal total: 80,6±8,8 kg; e tempo de prática no treinamento de força 5±3 anos). O experimento foi conduzido em duas sessões. Na primeira sessão, foi realizada a familiarização, coleta dos dados antropométricos e determinação de 10 repetições máximas (RMs) para o exercício agachamento parcial (AP) e total (AT). Na segunda sessão, os voluntários realizaram 10-RMs no exercício AP e AT com as sobrecargas ajustadas. Então, os participantes foram orientados a reportar a PSE. Um teste t de student pareado foi utilizado para comparar as médias. Os resultados mostram maior volume relativo (AP: 1,14±0,24xMC vs. AT: 0,87±0,24xMC; P<0,001) e volume absoluto (AP: 925±249 kg vs AT: 708±232 kg, respectivamente, P<0,001) no agachamento parcial quando comparado ao total. A PSE não apresentou diferenças significantes entre amplitudes (AP: 8,6±1,3 vs AT: 8,5±1,0; P=0,855). Conclui-se que a realização do AP possibilita a produção de maior volume absoluto e não influencia a PSE.

ABSTRACT

Abstract The treatment of patients with relapsed and/or refractory multiple myeloma has improved considerably in the last 15 years, after the introduction of proteasome inhibitors and immunomodulatory drugs. The first clinical trials with new proteasome inhibitors have produced exciting results, particularly those comparing triplet regimens with standard doublet regimens, with a gain in progression-free survival accompanied by an acceptable safety profile and either similar or better health-related quality of life. New proteasome inhibitors hold the potential to fill unmet needs in multiple myeloma management regarding improvement of clinical outcomes, including delayed progression of disease in high-risk patients. This review summarizes the main pharmacological properties and clinical outcomes of these agents, and discusses their potential to change the whole multiple myeloma therapeutic landscape.

ABSTRACT

ABSTRACT Introduction: The elastic wrap is widely used by different types of athletes and recreational practitioners of strength training in order to improve weightlifting performance. Objective: The objective was to investigate the acute effects of elbow wrap on strength performance, absolute volume, and rating of perceived exertion/discomfort during the bench press (BP) exercise. Methods: The experimental protocol was divided into three laboratory sessions. At the first session, a bench press familiarization phase was performed with (EW) and without (WEW) elastic elbow wrap. During the second session, the 1RM test was carried out in the bench press exercise under both EW and WEW conditions. At the third session, the repetition maximum (RM) test at 70% of 1RM (EW and WEW) was performed until concentric failure. After each session, subjects were consulted about their rate of perceived exertion (RPE), and discomfort (PSD). A paired student t-test was used to compare the values of 1RM and RMs with and without elastic wraps. Descriptive analysis was used for RPE and PSD. Results: For the 1RM test, there was a significant increase for the EW condition when compared to WEW (p<0.05). In the RMs test and absolute volume calculation, there was a significant increase for the EW condition (p<0.05). RPE did not differ in any of the conditions tested (p>0.05). PSD presented a high degree of discomfort with elastic wraps in all conditions. Conclusion: Elastic elbow wraps increase the load lifted in the 1RM test, and the maximum number of repetitions during the BP exercise, and consequently, the absolute volume. The elastic elbow wrap does not alter the subjective perception of effort, but it increases discomfort during exercise.


RESUMO Introdução: A banda elástica é muito utilizada por diferentes tipos de atletas e por praticantes de treinamento de força recreacionais, no intuito de melhorar o desempenho no levantamento de cargas. Objetivo: Investigar os efeitos agudos do uso da banda elástica de cotovelos no desempenho de força, no volume absoluto e percepção subjetiva de esforço durante o exercício supino reto livre. Métodos: Na primeira visita, foi realizada a familiarização com o exercício supino reto livre com banda (CB) e sem banda (SB) elástica de cotovelos. Na segunda visita, foi realizado o teste de 1RM no exercício supino reto livre, nas condições CB e SB. Na terceira visita, foi realizado o teste de repetições máximas até a falha concêntrica (RMs) a 70% de 1RM (CB e SB). Após cada teste, os sujeitos foram questionados quanto a sua percepção subjetiva de esforço (PSE) e de desconforto (PSD). Teste t de student pareado foi utilizado para comparar os valores de 1RM e RMs, com e sem banda elástica. Para a PSD e a PSE foram utilizadas análises descritivas. Resultados: No teste de 1RM foi verificado um aumento significante para a condição CB, quando comparado à condição SB (P<0,05). No teste de RMs e cálculo do volume absoluto, foi verificado um aumento significante para a condição CB (P<0,05). A PSE não apresentou diferenças em todas as condições testadas (P>0,05). A PSD apresentou alto grau de desconforto apenas com banda elástica em todas as condições. Conclusão: A banda elástica de cotovelos aumenta a carga levantada no teste de 1RM e o número de repetições máximas durante o exercício supino reto livre e, consequentemente, no volume absoluto. A banda elástica não altera a percepção subjetiva do esforço, mas aumenta o desconforto durante o exercício.

ABSTRACT

Abstract Objective: To review published data on oral manifestations of multiple myeloma. Methods: An electronic database search was performed of articles published from 1971 to November 2016 in order to identify studies that reported oral manifestations of patients with multiple myeloma. Case reports and case series with oral manifestations of multiple myeloma in English were included in the study. An additional search was performed of the references of the selected articles. Results: Thirty-seven articles that reported 81 patients with oral manifestations of multiple myeloma were selected: 30 case reports (82%) and seven case series (18%). The most common clinical features in the dental cavity were swelling (65.4%), bone pain (33.3%), paresthesia (27.1%) and amyloidosis lesions (11.1%). Osteolytic lesions detected on imaging exams were reported in the majority of the patients (90.1%) as plasmacytomas or 'punched-out' lesions. Conclusions: Swelling and osteolytic lesions represent the most common clinical and radiographic signs of the jaws relating to multiple myeloma, respectively.

ABSTRACT

The aim of the study was to compare rest QT interval and QTcorrected intervals of electrocardiogram in trained men with and without cervical spinal cord injury (CSCI) and investigate cardiac electrocardiogram parameters in trained men with CSCI submitted to maximal effort test. Thirty men were separated into three groups: Control without CSCI (CON, 25.3 ± 4.1 yrs, strength training: 3 days week-1; aerobic training 1day week-1; n = 10), high volume exercise (30.5 ± 4.3 yrs, 3 day week-1 rugby specific exercises, 60min. day-1; n = 12) and moderate volume of exercise (33.7 ± 5.9 yrs, 2 days week- 1 specific rugby exercises, 60 min. day-1; n = 8) with incomplete CSCI (C5-C7 cervical vertrebae) more than 12 months. Electrocardiogram was recorded in rest, during and after effort test. QT interval was significantly reduced (p = 0.001) in the high volume exercise group compared to control. Corrected QT interval showed no difference between moderate vs. high volume exercise group (p > 0.05). No changes were observed in QT, corrected QT, PR and QRS intervals of electrocardiogram between rest and post effort (p > 0.05). Thus, effort test does not change electrocardiogram parameters in CSCI subjects. High volume of week exercise promotes abnormalities in cardiac repolarization compared to a moderate training program.


O objetivo do presente estudo foi comparar o perfil dos intervalos QT e QT corrigido (QTc) em homens treinados com e sem lesão medular cervical (LMC) e investigar o perfil eletrocardiográfico de homens treinados com LMC submetidos ao teste de esforço máximo. Trinta homens foram separados em três grupos: controle sem LMC (CON, indivíduos fisicamente ativos; n = 10), LMC praticantes de alto volume de exercícios (praticantes de rugby em cadeira de rodas 180 min. Semana-1; n = 12) e LMC praticantes de moderado volume de exercícios (praticantes de rugby em cadeira de rodas 120 min. Semana-1; n = 8). Todos os participantes do grupo LMC apresentavam lesões incompletas (C5-C7) mais do que 12 meses. Eletrocardiograma foi registrado em repouso, durante e após o teste de esforço. O intervalo QT apresentou redução significativa (p = 0,001) no grupo de alto volume de exercícios quando comparado ao controle. O QTc não mostrou diferença entre os distintos volumes de exercícios (p > 0,05). Ambos os grupos LMC não apresentaram mudanças significativas no intervalo QT, QTc, intervalos PR e QRS entre o repouso e pós-esforço (p > 0,05). Concluimos que o alto volume de exercícios semanais parece promover anormalidades na repolarização cardíaca.

ABSTRACT

RESUMO Introdução: O drop jump é utilizado para melhorar da potência dos membros inferiores. Mantendo-se a altura de queda constante, a variação da técnica de aterrissagem pode alterar o desempenho e as características mecânicas do salto. Objetivo: Avaliar os efeitos da alteração da técnica de aterrisagem no desempenho e na força de reação do componente vertical do solo após drop jump. Métodos: Vinte e cinco homens saudáveis e fisicamente ativos (idade: 26±8 anos, massa corporal total: 75±10 kg, altura: 175±10 cm) realizaram quatro técnicas de aterrisagem após o drop jump: bounce drop jump (BDJ), drop jump com 90° de flexão do joelho (DJ90), drop jump com 135° de flexão do joelho (DJ135) e drop jump com 135° de flexão do joelho e com apoio das mãos no solo (DJ135A). Foram realizadas três tentativas para cada técnica, os sujeitos realizaram o drop jump caindo de uma plataforma de força de 40 cm de altura. As medidas de altura de salto, tempo de contato e impacto foram determinadas através da força de reação do componente vertical do solo, medida pela plataforma de força, em frequência de aquisição de 2.000 Hz. A ANOVA com medidas repetidas foi utilizada para comparar as diferentes técnicas. Resultados: A técnica BDJ apresentou menor altura de salto, menor tempo de contato e maior impacto que as demais condições (P < 0,001). A técnica DJ90 apresentou altura de salto similar às condições DJ135 e DJ135A e tempo de contato menor que as condições DJ135 e DJ135A, além de menor impacto que as demais condições (P < 0,001). Conclusão: As maiores alturas do salto vertical foram observadas para DJ90, DJ135 e DJ135A. O menor tempo de contato foi observado na técnica BDJ, seguido de DJ90. Quanto ao impacto, a técnica BDJ apresentou os maiores valores.


ABSTRACT Introduction: The drop jump is used to improve the power of the lower limbs. Keeping the drop height constant, the variation of the landing technique can modify the performance and the mechanical characteristics of the jump. Objective: To evaluate the effects of different landing techniques on the performance and the reaction force of the vertical component of the ground after drop jump. Methods: Twenty-five healthy and physically active men (age: 26±8 years, total body mass: 75±10 kg, height: 175±10 cm) performed four landing techniques after the drop jump: bounce drop jump (BDJ), drop jump with 90° of knee flexion (DJ90), drop jump with 135° of knee flexion (DJ135), and drop jump with 135° of knee flexion with hands resting on the ground (DJ135A). Three attempts were performed for each technique; the subjects performed the drop jump falling from a 40 cm high force platform. The measures of jump height, contact time and impact were determined by the force of reaction of the vertical component of the ground, measured by the force platform, at a frequency of acquisition of 2,000 Hz. The repeated measures by ANOVA were used to compare the different techniques. Results: The BDJ technique presented lower jump height, shorter contact time and greater impact than the other techniques (P<0.001). The DJ90 technique presented jump height similar to the DJ135 and DJ135A techniques and a short contact time (P<0.001) and a lower impact than the other techniques (P<0.001). Conclusion: The highest jumps were observed for DJ90, DJ135 and DJ135A. The lowest contact time was observed in the BDJ technique, followed by DJ90. Regarding the impact, the BDJ technique presented the highest values.


RESUMEN Introducción: El drop jump se utiliza para mejorar la potencia de las extremidades inferiores. Manteniéndose la altura de caída constante, la variación de la técnica de aterrizaje puede cambiar el rendimiento y las características mecánicas del salto. Objetivo: Evaluar los efectos del cambio de técnica de aterrizaje en el rendimiento y en la fuerza de reacción del componente vertical del suelo después del drop jump. Métodos: Veinticinco hombres sanos y física-mente activos (edad: 26±8 años, índice de masa corporal: 75±10 kg, altura: 175±10 cm) realizaron cuatro técnicas de aterrizaje después del drop jump: bounce drop jump (BDJ), drop jump flexionando las rodillas a 90o (DJ90), drop jump flexionando las rodillas a 135o (DJ135), y drop jump flexionando las rodillas a 135o con apoyo de las manos en el suelo (DJ135A). Se hicieron tres intentos para cada técnica; los sujetos realizaron el drop jump desde una plataforma de fuerza de 40 cm. La medición de la altura del salto, el tiempo de contacto y el impacto se determinaron por la fuerza de reacción del componente vertical del suelo, medida por la plataforma de fuerza, en frecuencia de adquisición de 2.000 Hz. Un ANOVA de medidas repetidas se utilizó para comparar las diferentes técnicas. Resultados: La técnica BDJ mostró menor altura del salto, menos tiempo de contacto y un mayor impacto que las otras condiciones (P < 0,001). La técnica DJ90 presentó un salto de altura similar a las condiciones de DJ135 y DJ135A y menos tiempo de contac-to que las condiciones de DJ135 y condiciones DJ135A, e impacto más bajo que las otras condiciones (P < 0,001). Conclusión: Las mayores alturas de salto vertical se observaron en DJ90, DJ135 y DJ135A. El tiempo de contacto más bajo fue el de la técnica BDJ, seguida de DJ90. En cuanto al impacto, la técnica BDJ presentó los valores más altos.

ABSTRACT

The Durie/Salmon staging system continues to be used worldwide in patients with multiple myeloma. However, in recent years, new systems have been proposed. The International Myeloma Working Group performed a retrospective study with 11,179 patients and proposed an "International Staging System" utilizing serum levels of â2 microglobulin and albumin. In addition, current research has focused on the usefulness of cytogenetic and molecular data as prognostic factors. These data suggest that these parameters are powerful discriminators of a poor prognostic group of myeloma patients. Indeed, these prognostic indexes have been utilized in clinical trials, with interesting and encouraging results.


O esquema de Durie / Salmon continua a ser utilizado para estadiar os pacientes com mieloma múltiplo. Recentemente, um novo sistema mais simples e eficaz foi proposto. O "International Myeloma Working Group" realizou um estudo retrospectivo com 11.179 pacientes e a partir destes dados propôs a criação de um "International Staging System (ISS)" utilizando os níveis séricos de ß2 microglobulina e de albumina ao diagnóstico. Além do ISS a pesquisa está voltada para identificar alterações citogenéticas e moleculares que se correlacionem com o prognóstico no mieloma múltiplo. Estes fatores prognósticos têm sido utilizados para estratificar pacientes em ensaios clínicos com resultados promissores.

ABSTRACT

PURPOSE: Despite the advances in microvascular free tissue transfer for intraoral reconstruction, this surgery is not recommended for all patients. In specific cases, the pedicled temporoparietal galeal flap may be an option for reconstructive procedures in the head and neck regions. The objective of this paper is to present the anatomical aspects of a galeal flap based on the superficial temporal vessels and to test its potential for reconstructing diverse sites of the oral cavity and pharynx. METHODS: We performed 40 dissections on 34 fresh adult cadavers. The flap vascular anatomy was studied by injecting latex into the superficial temporal vessels. A standardized square-shape flap measuring 10 x 10 cm², pedicled on the superficial temporal vessels, was raised. Oral cavity and oropharynx reconstruction simulations were performed after flap transposition into the mouth by passing it under the zygomatic arch. Hypopharyngeal reconstruction was tested by transposing the flap to the neck under the facial nerve. RESULTS: After latex injection, a rich vascular network over the temporoparietal galea was observed directly from the superficial temporal artery, and a well-vascularized flap based on this vessel was raised. In the reconstruction simulations, the flap was shown to be suitable for the coverage of hypothetical defects in most oral cavity and pharyngeal sites, mainly the retromolar trigone, tonsil area, and buccal mucosa. CONCLUSIONS: A galeal flap based on the superficial temporal vessels presents favorable anatomical characteristics for oral cavity and pharyngeal reconstruction.

ABSTRACT

A quimioterapia em altas doses seguida de transplante autólogo de células-tronco hematopoéticas vem se constituindo ao longo das últimas décadas em um importante instrumento terapêutico, devendo fazer parte da estratégia de tratamento da maior parte dos pacientes com mieloma múltiplo, particularmente daqueles com idade inferior a 65 anos. Pelo menos dois importantes estudos randomizados mostraram vantagens para esta estratégia quando comparadas à quimioterapia convencional. No entanto, a quase totalidade destes pacientes irá recair, necessitando de algum tratamento adicional. A utilização de um segundo transplante, manutenção com talidomida e a introdução de novas drogas como o bortezomibe poderão representar um avanço, melhorando os resultados da estratégia de tratamento do mieloma múltiplo.


High dose chemotherapy followed by autologous stem cell transplantation has been recognized as an important step in the treatment of multiple myeloma. At least two well designed randomized studies showed better outcomes in patients treated with high doses compared to those treated with conventional chemotherapy. Nowadays, autologous stem cell transplantation should be considered for all under 65-year-old patients. Although autologous stem cell transplantation has modified the prognosis of myeloma, almost all patients still relapse some time after a single transplant, and then another therapeutic approach becomes necessary. With the aim of improving the results in the treatment of myeloma, new approaches including tandem stem cell transplantation, maintenance with thalidomide and new drugs such as bortezomib are being tested. Strategies including these approaches and autologous stem cell transplantation may improve the results of the treatment of myeloma in the future.

ABSTRACT

A insuficiência renal (IR) é uma complicação freqüente em pacientes com mieloma múltiplo (MM) podendo estar presente em 35 por cento dos pacientes ao diagnóstico e em mais de 50 por cento durante a evolução da doença. O mecanismo mais freqüente de IR é o assim chamado "rim do mieloma" decorrente da excreção de cadeias leves provocando um dano tubular. Outros mecanismos de IR são o depósito tissular de cadeias leves e a Síndrome de Fanconi Adquirida. Determinados fatores podem precipitar e agravar a IR tais como a hipercalcemia, hiperuricemia, desidratação, hiperviscosidade e drogas nefrotóxicas. O tratamento de suporte deve ser feito em todos os pacientes e nos casos em que a função renal não possa ser revertida deve ser considerado o tratamento dialítico. O tratamento específico do MM em pacientes com IR tem papel importante e impacto na sobrevida. A quimioterapia inicial mais adequada é VAD ou combinação de ciclofosfamida e dexametasona. Quimioterapia em altas doses e transplante autólogo podem ser considerados para pacientes com idade inferior a 60 anos e um bom performance status (PS).


Renal insufficiency is a frequent complication in patients with Multiple Myeloma (MM). It occurs in 35 percent of newly diagnosed patients and in more than 50 percent during the evolution of the disease. The most frequent mechanism of renal failure is the so-called "myeloma kidney", which is the renal tubular damage caused by the excretion of light chains. Other mechanisms of renal damage are light chain tissue deposition and acquired Fanconi's syndrome. This renal impairment might be aggravated by precipitating factors such as hypercalcemia, hyperuricemia, dehydration, hyperviscosity, and nephrotoxic drugs. Supportive measures must be taken for all patients; for those with an irreversible renal function, dialysis must be considered. Specific myeloma treatment has an important prognostic value for patients with renal impairment. The recommendation of induction treatment is VAD or a combination of cyclophosphamide and dexamethasone. High dose chemotherapy followed by autologous stem cell transplant can be considered for under 60-year-old patients with a good performance status.

ABSTRACT

As afeccoes malignas das tres regioes da faringe - nasofaringe, orofaringe e hipofaringe - sao bastante distintas entre si no que diz respeito ao quadro clinico e ao tratamento. Enquanto na nasofaringe os tumores sao menos diferenciados e tratados principalmente pela radioterapia, os tumores da orofaringe e da hipofaringe sao mais diferenciados e, como regra, respondem melhor a terapeutica cirurgica associada a radioterapia pos-operatoria. Na terapeutica dos tumores da faringe, os linfonodos cervicais devem ser tratados pelo esvaziamento cervical e / ou pela radioterapia

ABSTRACT

Os diferentes tipos de esvaziamentos cervicais e suas indicacoes sao discutidos em conjunto com uma breve revisao da sua evolucao historica e da divisao das cadeias linfaticas cervicais em uso corrente pelos cirurgioes. De 1993 a 1997, foram realizados 508 esvaziamentos na Disciplina de Cirurgia de Cabeca e Pescoco da Faculdade de Medicina da Universidade de Sao Paulo. Desses, 123 relacionaram-se ao tratamento de neoplasias da glandula tireoide e 385 a outros tumores, principalmente o carcinoma epidermoide da mucosa de revestimento das vias aereas e digestivas do segmento cervical e cefalico

ABSTRACT

As doencas das glandulas salivares podem ser divididas em neoplasicas (benignas e malignas), obstrutivas, infecciosas, de origem sistemica e sialoses. A maior parte das doencas acometem as duas maiores glandulas salivares, quais sejam, a parotida e a submandibular. Os tumores de glandulas salivares apresentam uma grande variedade de tipos histopatologicos, sendo o mais frequente o adenoma pleomorfico. A parotida apresenta peculiaridades anatomicas de fundamental importancia para o tratamento cirurgico das neoplasias, descritas neste trabalho. Procuramos abordar as doencas mais comuns com maiores detalhes, esclarecendo o aspecto diagnostico e terapeutico

ABSTRACT

O pseudotumor inflamatório de linfonodo (PIL), lesäo inflamatória expansiva crônica nao neoplásicade linfonodo, foi descrito por Perrone e cols1, em 1988, através de comparaçöes com achados histopatológicos encontrados em pseudotumor inflamatório de pulmäo e outros órgäos. Histologicamente o PIL caracteriza-se por lesöes vasculares e infiltraçäo celular reativo polimorfo, e clinicamente (massa cervical, febre e perda ponderal) possui comportamento incerto, por vezes simulando neoplasia maligna. Por essas características o PIL possui como principal diagnóstico diferencial o linfoma. Discutimos esta questäo através da revisäo de literatura e relato de um caso, onde houve dificuldades no diagnóstico.
