    Full Text Available Objectives: we analyzed the characteristics of patients with gastric tumors diagnosed with multiple malignant primary neoplasm (MMPN in the Health District of León. Material and methods: using the information in the Tumor Registry at León Hospital patients selected were those with gastric neoplasms diagnosed between 1993 and 2002. A follow-up was performed until December 31, 2004, and the characteristics of patients diagnosed with a second neoplasm were analyzed. Results: MMPN prevalence was 1,96%; 56% of patients had a history of cancer in first-degree relatives. The most frequent second neoplasms were digestive (26% and urologic (21%; 87% of patients were diagnosed with a second neoplasm within the first two years. No significative differences in survival were observed among patients with synchronous or metachronous MMPN. Conclusions: MMPN in patients with gastric neoplasms is a relevant problem. While external carcinogenic agents could act as promoters in the development of second neoplasms, these patients seem to have a genetic background favoring the development of MMPN. Secondary prevention is the best measure to avoid MMPN development.Objetivos: analizar las características de los pacientes con tumores gástricos diagnosticados de una neoplasia primaria maligna múltiple (NPMM en el área sanitaria de León. Pacientes y método: utilizando los datos del Registro de Tumores del Hospital de León se han seleccionado aquellos pacientes con tumores gástricos diagnosticados entre 1993 y 2002.

    Full Text Available El objetivo de este estudio es presentar la epidemiología descriptiva del cáncer en los niños menores de 15 años a nivel mundial y nacional. Se realizó una revisión de la literatura internacional y nacional de los artículos publicados sobre cáncer en los niños, seleccionando aquellos que trataran los aspectos epidemiológicos de tiempo, lugar y persona y analizándose tanto la incidencia como la mortalidad por cáncer en niños. La incidencia mundial es de 100 a 150 casos x 10(6 niños/año. La incidencia específica varía de acuerdo al tipo cáncer, el país o región que se estudie. El patrón latinoamericano de neoplasias lo constituyen las leucemias, los linfomas y los tumores del sistema nervioso central (TSNC; en el norteamericano y europeo los TSNC ocupan el segundo lugar; y en el africano predominan los linfomas. La incidencia es mayor en los menores de 5 años en el medio urbano y existe un incremento de 1% anual de cánceres en los niños de Estados Unidos de América. La mortalidad por cáncer en niños ha disminuido de forma importante principalmente en los países desarrollados, como Estados Unidos e Inglaterra; en los subdesarrollados permanece estable o hay una leve disminución. La incidencia es mayor en países desarrollados; sin embargo, en los países subdesarrollados puede estar subestimada. Aún hay muchos datos que se desconocen sobre la epidemiología del cáncer en el niño, por lo que son necesarios más estudios.

    Full Text Available RESUMO: Os alimentos funcionais têm sido empregados como adjuvantes no tratamento do câncer de mama. Neste estudo avaliaram-se as respostas hematológicas e bioquímicas clínicas à ação de um alimento funcional administrado a cadelas com diagnóstico de neoplasia mamária maligna. Após a mastectomia, 16 cadelas foram divididas em dois grupos: suplementadas (S e não suplementadas (NS com um composto comercial contendo Saccharomyces cerevisiae, mananoligossacarídeos e nutracêuticos. Ambos grupos receberam tratamento quimioterápico com doxorrubicina e carboplatina, alternadamente, em intervalos de 21 dias, por oito sessões, totalizando 168 dias de tratamento. As avaliações clínicas e laboratoriais foram realizadas nos momentos de aplicação do tratamento. Os resultados dos perfis hematológico (hemograma, leucograma e plaquetograma e bioquímico sérico (ureia, creatinina, albumina, bilirrubina total e direta, alanina aminotransferase, fosfatase alcalina e gama glutamiltransferase - GGT foram analisados pelo teste de Kruskall Wallis. No grupo S comprovou-se elevação do peso corporal e não foram observados transtornos gastrointestinais ou outros sinais de alteração clínica ao longo do tratamento. Diferentemente no grupo NS, ocorreu perda de peso e alterações clínicas, como diarreia e vômito. No quadro hematológico, constatou-se leucopenia por linfopenia no grupo de cadelas NS e preservação do valores dentro dos parâmetros considerados normais para a espécie no grupo S. Dentre todas as variáveis da bioquímica clínica, constatou-se apenas a elevação da atividade sérica da GGT nos animais do grupo NS, sem alterações no grupo S. Conclui-se que cadelas com neoplasia mamária quando suplementadas com com alimento funcional imunoestimulante apresentam melhor condição clínica, hematológica e dos níveis bioquímicos, particularmente da GGT.

    Full Text Available This research was conducted to assess some psychologic and social factors in families with children with malignant neoplasia. A cross-sectional and correlation study was performed in a group of 38 mothers of patients aged 0-18 months, who were seen in “Juan Manuel Márquez” Children Hospital, in Marianao, in June and July 2005. The following techniques were applied: Family Performance Perception Test (FPPT, social support questionnaire (SSQ, and confrontation scale (CS. The information obtained was processed by means of the SPSS statistical program in its version for Window 98. The results showed that most of the families were functional, and that mothers needed a lot of social support, mainly of emotional support. It was concluded that there was no dependence between the family functioning and the variables which with it was related; most of the mothers felt satisfied with the social support received, and the confrontation strategies they used the most were to focus their attention on the positive, and to worry and concentrate themselves on solving the problem.

    Full Text Available OBJETIVO: No Brasil, a tuberculose ileocecal isolada, na ausência de tuberculose pulmonar ativa ou cicatrizada, é rara, sendo freqüentemente confundida com neoplasia e a doença de Crohn. MÉTODOS: Os autores apresentam oito doentes com essas características, tratados por cirurgia, em período de 20 anos. A dor abdominal na fossa ilíaca direita foi o principal sintoma (100%, seguido da presença de perda de peso (62,5%, febre, náuseas e vômitos e fadiga em 50% dos doentes. Sete enfermos (87,5% apresentaram massa palpável na fossa ilíaca direita. A duração média dos sintomas foi de 14,7 meses, variando de 5 a 36 meses. Todas as lesões foram detectadas pelo enema opaco e mimetizavam aspecto neoplásico. A colonoscopia foi realizada em três doentes, evidenciando lesões sub-oclusivas da região íleo-cecal em dois; as biópsias foram sugestivas de tuberculose, não sendo possível diferenciá-las da doença de Crohn. RESULTADOS: Seis enfermos com diagnóstico presuntivo de neoplasia foram submetidos a cirurgia eletiva, realizando-se neles a colectomia direita clássica. Os outros dois, com suspeita de tuberculose, foram operados na vigência de obstrução intestinal, sendo submetidos a ressecção limitada (ileocecectomia. O estudo anatomopatológico estabeleceu o diagnóstico final pelo encontro de necrose caseosa e de bacilos álcool ácido-resistentes no intestino ou nos linfonodos. A evolução pós-operatória foi satisfatória, com pequena morbidade resolvida clinicamente. Posteriormente, todos os doentes receberam o esquema tríplice por 12 meses, variando a droga de acordo com a época do tratamento. CONCLUSÃO: Apesar de rara, a tuberculose hipertrófica ileocecal isolada freqüentemente é confundida com neoplasias e com a doença de Crohn, devendo ser lembrada no diagnóstico diferencial das lesões localizadas no quadrante inferior direito do abdome.BACKGROUND: Isolated ileocecal involvement by tuberculosis in the absence

    Full Text Available OBJETIVO: Avaliar a ação da timulina em pacientes com neoplasia maligna, submetidos ao tratamento, com e sem quimioterapia e radioterapia complementar (QT/RT. MÉTODO: Estudo retrospectivo realizado em 50 pacientes, analisando as variações das taxas de leucócitos, linfócitos totais e da relação de linfócitos CD4/CD8 após imunoestimulação com timulina. RESULTADOS: No grupo submetido à QT/RT ocorreu um aumento do número de leucócitos após seis meses em 43,33% dos casos, e em 83,33% após 12 meses. Com relação aos linfócitos totais, após seis meses, 63,33% apresentaram níveis maiores, e depois de 12 meses isto ocorreu em casos 90% dos casos. A relação de linfócitos CD4/CD8 mostrou um aumento em 66,66%, e em 90% depois após 6 e 12 meses respectivamente. A análise estatística se mostrou significante com o teste de ANOVA one way. No grupo não submetido à QT/RT a elevação dos níveis de leucócitos ocorreu em 85% dos pacientes aos seis meses e em 90% aos 12 meses. As taxas de linfócitos se elevaram em 60% dos casos em seis meses e em 85% após 12 meses. A relação CD4/CD8 se tornou maior tanto aos seis como aos 12 meses em 65%. A análise estatística mostrou relevância com o teste "t" de Student e o de ANOVA one way. Não houve necessidade de interrupção dos ciclos de QT/RT e nenhum paciente referiu intolerância à timulina. CONCLUSÃO: O uso da timulina foi capaz de restaurar a resposta imune, reduzir os danos imunossupressores e colaterais induzidos pela terapia antineoplásica e não apresentou efeitos colaterais.

    Full Text Available OBJETIVOS: O estudo procurou identificar e analisar as oportunidades de diagnóstico precoce para neoplasias malignas de mama, disponíveis para as mulheres do município de Botucatu. MÉTODOS: Foram entrevistadas por telefone, segundo sorteio aleatório, 261 mulheres com idade de 30 anos ou mais. RESULTADOS: A média de idade foi de 51 anos e 49,45% das entrevistadas apresentaram escolaridade de nove anos ou mais; 80% receberam orientações gerais sobre prevenção do câncer de mama e 86,9% orientações específicas sobre autopalpação; 78,9% das mulheres realizaram o auto-exame das mamas e destas somente 27% o fizeram corretamente. O exame clínico das mamas foi realizado em 76,2% das entrevistadas e a mamografia em 35,6%; se o exame de mamografia fosse solicitado por médicos e estivesse disponível, 83,1% das mulheres estariam dispostas a realizá-lo. CONCLUSÃO: A prevalência e a mortalidade da doença são maiores nas mulheres idosas. Neste estudo observou-se que estas apresentaram uma taxa menor de oportunidades de diagnóstico precoce, pois eram menos informadas sobre a periodicidade correta da autopalpação e apresentaram uma menor freqüência de mamografia e de exame clínico das mamas do que as mais jovens. O grau de escolaridade mostrou também significância estatística, visto que as mulheres com mais anos de estudo tiveram melhores oportunidades do que as com pouco estudo.PURPOSE: The study tried to identify and to analyze the opportunities of early detection of breast cancer available for the women of Botucatu County. METHODS: A sample of 261 women, 30 year-old or more was interviewed by telephone.

    Full Text Available FUNDAMENTOS - O DNA viral pode atuar como oncogene, favorecendo o desenvolvimento de neoplasias, como as linfoides e da pele. Entre esses vírus, encontram-se alguns herpes-vírus humanos. OBJETIVO - Identificar a presença de DNA do herpes-vírus humano tipo 1 em neoplasias epiteliais pré-malignas,malignas e pele normal de indivíduos controle, avaliando seu papel na carcinogênese. MÉTODOS - Identificação, por reação em cadeia da polimerase, do DNA viral do tumor e pele sã de 41 pacientes e comparação com grupo controle, sem neoplasia. Análise estatística: Testes de Fisher e de McNemar. RESULTADOS - O vírus foi identificado em 20 indivíduos sem e em 21 com neoplasia. Destes últimos, 11 o expessaram apenas nas células tumorais. A diferença, entretanto, não foi estatisticamente significante. CONCLUSÕES - Parece não haver relação direta entre o encontro do DNA viral na pele sã e na pele tumoral. Sua presença pode facilitar o desenvolvimento da neoplasia ou apenas coincidir de se localizar onde esta já ocorreu.BACKGROUND - Viral DNA may act as an oncogene, especially in skin and lymphoid organs. This group includes some human herpes virus. OBJECTIVE - To identify human herpes virus type 1 DNA in pre-malignant and malignant skin samples of epithelial tumors comparing to normal skin to determine its role in carcinogenesis. METHODS - Forty-one patients with epithelial tumors were submitted to biopsies from tumor and normal skin. The control group comprised 41 biopsies from patients with other dermatoses than cancer. After DNA extraction, polymerase chain reaction was performed to identify 199-bp band. The results were statistically evaluated by Fisher and McNemar tests. RESULTS - The virus was identified in 20 subjects without cancer and in 21 with skin cancer. From these, 11 expressed it only in tumor cells. This difference was not significant. CONCLUSION - There seem to be no direct relation between viral findings in normal

    Full Text Available A finalidade do presente trabalho foi estudar algumas das proteínas fibrilares da matriz extracelular de 54 neoplasias mamárias benignas e malignas na espécie canina, utilizando métodos histoquímicos: Picrosirius associado à polarização para fibras colágenas , método de Gordon - Sweats para fibras reticulares e método de Weigert com e sem oxidação para fibras elásticas. Evidenciou-se na matriz uma grande variabilidade na quantidade, distribuição e características dos componentes matriciais presentes nos diferentes tipos de neoplasias. Detectou-se, assim, colágeno I, III e elementos do sistema elástico, distribuídos diferentemente nas neoplasias benignas e malignas. O método Picrosirius simples e associado à polarização permitiu a visualização do colágeno sob a forma de fibras espessas distribuídas irregularmente no estroma dos carcinomas e de modo mais ordenado e regular nas neoplasias benignas e, fibras mais finas, em menor quantidade, irregularmente e aleatoriamente dispostas nos carcinomas e regularmente nas neoplasias benigna. Sob luz polarizada os feixes de fibras colágenas , apresentaram diferentes comprimentos, avermelhados ou amarelados e fortemente birrefringentes, sugerindo serem colágeno tipo I e, entremeando as fibras, algumas mais finas ,pálidas, esverdeadas e fracamente birrefringentes, presumivelmente colágeno tipo III. Em áreas condrometaplásicas, tanto nos carcinomas como nas neoplasias benignas notou-se que os feixes colágenos apresentavam-se com fibras finas, paralelas, limitando regiões estreitas onde os condrócitos se aninhavam, e, rodeando esta área, feixes de fibras espessas, anastomosadas, dispostas irregularmente nos carcinomas e ordenadamente e paralelas nas neoplasias benignas. Sob luz polarizada, essa população entre condrócitos era formada por fibras pálidas e amareladas, sugerindo padrão tipo II e na faixa circundante, feixes fortemente birrefringentes, sugerindo o padr

    Full Text Available A neoformação vascular constitui evento essencial para que ocorra o desenvolvimento humano. Nesta fase, o sistema vascular sofre expansão. Células endoteliais maduras (ECs irão compor a parede dos vasos, enquanto células endoteliais oriundas da medula óssea (MO migram para locais de neoformação vascular com subseqüente diferenciação em células endoteliais maduras. Processos fisiológicos e patológicos como câncer têm a angiogênese como importante componente. Estudos correlacionam a angiogênese com a agressividade tumoral em alguns tipos de tumores incluindo hematológicos, o que ressalta a importância da terapia antiangiogênica como alvo de pesquisas cada vez mais profundas. Neste artigo de revisão enfocamos o papel da angiogênese nas neoplasias hematológicas com ênfase em possíveis alvos terapêuticos.Vascular neoformation is an essential event in the development of the human body. In this phase vascular networks undergo expansion. Mature endothelial cells constitute the structure of vessel walls so endothelial cells from bone marrow migrate to sites of vascular neoformation with subsequent differentiation as mature endothelial cells (endothelial progenitor cells. Physiopathological and pathological processes such as cancer use angiogenesis as an important component for growth. Studies correlate angiogenesis with aggressive tumors for some types of tumors, including hematological malignancies, thereby highlighting the importance of anti-angiogenic therapy.

    Full Text Available OBJETIVO: Relatar a experiência do nosso Serviço com a descompressão cirúrgica da árvore biliar através de uma hepatojejunostomia periférica. MÉTODO: Entre julho de 2000 a julho de 2005, 11 pacientes foram à laparotomia para ressecção de tumores do hilo hepático e, durante o trans-operatório, apresentavam lesões irressecáveis. Os dados analisados foram: idade, sexo, morbidade, mortalidade, dosagem de bilirrubinas séricas pré-operatórias e no 7ºdia de pós-operatório, prurido pré e pós-operatório e sobrevida. RESULTADOS: A idade média dos pacientes foi de 67 anos, seis eram mulheres e cinco eram homens. Icterícia estava presente em 100% dos casos e prurido em 80%. Seis pacientes tiveram o diagnóstico de neoplasia de vesícula biliar e cinco de colangiocarcinoma. Ocorreram três óbitos intra-hospitalares. A dosagem média no pré-operatório de bilirrubina total foi 19,33mg/dl e bilirrubina direta 16,81mg/dl e no pós-operatório 4,88mg/dl e 3,64mg/dl, respectivamente. Oito pacientes que receberam alta hospitalar tiveram sobrevida média de oito meses, evoluindo sem icterícia e prurido. CONCLUSÃO: A hepatojejunostomia periférica pode ser considerada uma boa opção como tratamento paliativo . Ela demonstrou ser segura, com sangramento mínimo, rápida execução e mortalidade aceitável, melhorando significativamente a icterícia, o prurido e fornecendo uma sobrevida satisfatória.

Las estenosis intrínsecas malignas del estomago son producidas generalmente por tumores derivados de sus diferentes tejidos y por consiguiente se agrupan en dos grandes tipos, a saber: los sarcomas, los carcinomas y los adenocarcinomas, según se deriven de los tejidos de sostén o conjuntivos y de los tejidos glandulares o epiteliales. Es importante tener en cuenta esto, pues la sintomatología de unos y otros varia considerablemente, ya que afectan funciones diferentes.

    En cualquier caso, la amenorrea primaria es un trastorno poco común que resulta de errores fetales en el desarrollo gonadal, gonadoductal y genital en el 60% de los casos. La mitad de estos están constituidos por síndromes de disgenesia gonadal (típica tipo Turner, mixta y pura, un tercio por disgenesia mulleriana y un sexto, por errores en el desarrollo genital.

    2016-12-01

    Lentigo maligna is the most common type of facial melanoma. Diagnosis is complicated, however, as it shares clinical and dermoscopic characteristics with other cutaneous lesions of the face. Reflectance confocal microscopy is an imaging technique that permits the visualization of characteristic features of lentigo maligna. These include a disrupted honeycomb pattern and pagetoid cells with a tendency to show folliculotropism. These cells typically have a dendritic morphology, although they may also appear as round cells measuring over 20μm with atypical nuclei. Poorly defined dermal papillae and atypical cells may be seen at the dermal-epidermal junction and can form bridges resembling mitochondrial structures. Other characteristic findings include junctional swelling with atypical cells located around the follicles, resembling caput medusae. Reflectance confocal microscopy is a very useful tool for diagnosing lentigo maligna. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

A possibilidade de cura aumenta com o diagnóstico precoce, daí a importância dos programas de rastreamento populacional do câncer colorretal. O presente estudo analisou, retrospectivamente, 66 pacientes submetidos a ressecções do cólon por neoplasia em um período de 58 meses no Hospital Universitário da Universidade de São Paulo. Os pacientes foram divididos em dois grupos: grupo 1, submetidos a cirurgia eletiva (28 pacientes, e grupo 2, submetidos a cirurgia de urgência (38 pacientes. Os grupos foram comparados com relação às variáveis sexo, idade, apresentação clínica, aspectos da técnica cirúrgica, sítio anatômico da lesão, estádio patológico, taxas de complicações, permanência hospitalar pós-operatória e óbitos na internação. Verificou-se no presente estudo que a idade entre os grupos foi semelhante. Houve uma predominância do sexo masculino entre os pacientes operados de urgência. No grupo de cirurgia eletiva, o principal sintoma foi a hematoquezia, enquanto os operados na urgência, tinham como principal queixa dor abdominal. A grande maioria dos pacientes, no momento da cirurgia, apresentava-se sintomática há meses. Os pacientes operados na urgência apresentaram mais tumores pT4 e os operados eletivamente apresentaram mais neoplasias em estádio I. Em ambos os grupos, o caráter oncológico dos procedimentos foi preservado, bem como foi alto o índice de anastomoses primárias (81,8%. As taxas de complicações pós-operatórias, o tempo de permanência hospitalar pós-operatório e a mortalidade foram semelhantes.Colon cancer is a disease with high frequency and mortality rates, which treatment is based, fundamentally, on surgical resection.

    Full Text Available Schwannoma é uma neoplasia mesenquimal, usualmente solitária, encontrada no mediastino, retroperitônio ou pelve, sendo rara sua apresentação na parede torácica. OBJETIVO: Relatar o caso de um paciente masculino, tabagista, com um nódulo pulmonar direito com características de malignidade, detectado em radiografia de tórax de rotina, cujo diagnóstico anatomopatológico foi de schwannoma benigno de nervo intercostal. MÉTODOS: Revisaram-se os dados referentes ao quadro clínico, exames laboratoriais e de imagem (radiografia e tomografia computadorizada de tórax do caso em estudo, assim como os exames anatomopatológico e imuno-histoquímico do espécime cirúrgico. RESULTADOS: O paciente foi submetido à toracotomia direita diagnóstica com ressecção da tumoração. O exame anatomopatológico convencional mostrou células tumorais de aspecto fusiforme, dispostas em paliçada, formando os corpos de Verocay, compatível com schwannoma intercostal. A imuno-histoquímica foi positiva para proteína S-100, vimentina e enolase, e negativa para neurofilamentos. CONCLUSÃO: O diagnóstico definitivo de schwannoma só é possível por meio da análise histopatológica e imuno-histoquímica da lesão. Seu aspecto celular, associado à atividade mitótica e a áreas de pleomorfismo, pode levar ao diagnóstico incorreto de malignidade. A imuno-histoquímica, por meio da proteína S-100, é útil na caracterização da benignidade da lesão, já que não é detectada nas lesões malignas. Os schwannomas de parede torácica podem simular neoplasias pulmonares na radiografia e tomografia computadorizada de tórax.

Com o aumento da sobrevida dos pacientes com câncer, houve um aumento de neoplasias primárias múltiplas. Este estudo objetiva avaliar a freqüência de neoplasias primarias múltiplas em pacientes com diagnóstico de câncer colorretal do Setor de Oncologia da Disciplina de Gastroenterologia da Universidade Federal de São Paulo. Pacientes e Métodos - No período de 1993 a 1998, 145 pacientes com câncer colorretal foram acompanhados no Setor de Oncologia da Disciplina de Gastroenterologia da Universidade Federal de São Paulo. Destes, cinco pacientes (3,4% tinham neoplasias primárias múltiplas. O segundo tumor foi confirmado por exame histológico, sendo excluídas as possibilidades de metástase. Resultados - A idade média dos doentes com neoplasias primárias múltiplas foi de 60,6 anos, quatro eram do sexo feminino e um do masculino, três apresentaram doença no reto, um no cólon direito e um no cólon esquerdo. Os outros sítios foram mama, útero, útero e vagina, pele e lábio. Um paciente foi a óbito e os outros estão em acompanhamento, sendo que dois, há mais de três anos. Dois pacientes tinham sido submetidos a radioterapia pélvica antes do aparecimento da neoplasia colorretal. Em um paciente o tumor colorretal antecedeu o outro câncer e em quatro apareceu posteriormente ao diagnóstico da outra neoplasia primária. Discussão - A prevalência de neoplasias primárias múltiplas foi de 3,4%, sendo maior no sexo feminino. Câncer de endométrio foi o outro tumor maligno mais freqüente. Quarenta por cento dos nossos pacientes foram submetidos a radioterapia. Acreditamos ser importante o acompanhamento dos pacientes para o diagnóstico precoce de uma nova neoplasia em qualquer paciente que já tenha apresentado um câncer.Introduction - Multiple primary

Durante a exposição a esses agentes desencadeadores, há um aumento rápido e sustentado da concentração de cálcio mioplasmático (Ca2+ induzido pela hiperativação dos receptores de rianodina (RYR1 do músculo esquelético, causando uma alteração profunda na homeostase de Ca2+, caracterizando um estado hipermetabólico. RYR1, canais de libertação de Ca2+ do retículo sarcoplasmático, é o principal local de susceptibilidade à HM. Várias mutações no gene que codifica a proteína RYR1 foram identificadas, mas outros genes podem estar envolvidos. Atualmente, o método padrão para o diagnóstico de sensibilidade à HM é o teste de contratura muscular para exposição ao halotano-cafeína (CHCT e o único tratamento é o uso de dantroleno. No entanto, com os avanços no campo da genética molecular, um pleno entendimento da etiologia da doença pode ser fornecido, favorecendo o desenvolvimento de um diagnóstico preciso, menos invasivo, com o teste de ADN, e também proporcionar o desenvolvimento de novas estratégias terapêuticas para o tratamento da HM. Logo, esta breve revisão tem como objetivo integrar os aspectos clínicos e moleculares da HM, reunindo informações para uma melhor compreensão desta canalopatia.

  7. Ionizing radiation and neoplasia

    1986-01-01

    Among the well accepted causes of neoplasia, ionizing radiation is quite prominent. Its oncogenic role was suspected by a few pioneers in the field of radiation biology, and some evidence for its oncogenicity has been available for almost 80 years. Since then unquestionable and abundant proof, statistical and experimental, has linked radiation with multiple tumors in mammals. Other forms of radiation (e.g., ultraviolet) are also causally related to neoplasia. This review, however, refers only to the tumors associated with ionizing radiation, either electromagnetic (i.e., gamma and x-rays) or particulate (alpha particles, neutrons, etc.). The field of radiation oncogenesis can be compared to a sea of hypotheses, with a few solid islands of facts. This paper considers the facts (specific radiation-induced neoplasms, risk data, etc.) and then considers some of the hypotheses (possible mechanisms of radiation oncogenesis)

    Full Text Available O papilomavírus humano (HPV é um fator etiológico bem estabelecido para o câncer cervical. Esse vírus de DNA infecta primariamente o epitélio e pode induzir lesões benignas ou malignas na pele e na mucosa. Alguns HPVs são considerados de alto risco, responsáveis pela progressão das lesões precursoras até câncer cervical. A infecção genital pelo HPV é comum em mulheres jovens e geralmente é transitória. Uma pequena proporção de mulheres infectadas desenvolve câncer cervical, implicando o envolvimento de fatores ambientais e fatores genéticos na carcinogênese. Essa revisão aborda a estrutura viral, classificação e patologia do HPV, história natural e fatores de risco para neoplasia cervical e perspectivas futuras com a vacina anti-HPV.Human papillomavirus (HPV has been established as an important etiological factor for the development of cervical cancer. This DNA virus primarily infects the epithelium and can induce benign and malignant lesions of the mucous membranes and skin. Some HPVs are considered high risk due to their role in malignant progression of cervical tumors. Genital HPV infections are common and usually transient among young sexually active women. Only a small fraction of infected women develop cervical cancer, implying the involvement of environmental and genetic cofactors in cervical carcinogenesis. Classification, virology, pathology, natural history, epidemiological features of genital HPV infection, and future prospects for cervical cancer prevention with HPV vaccines will be reviewed here.

    Full Text Available São apresentados 18 casos de neoplasias primárias do duodeno, salientando-se sua raridade e as dificuldades diagnósticas, a despeito dos modernos recursos endoscópicos e de identificação por imagem. A literatura revela que de 1% a 10% de todos os tumores do aparelho digestório se situam no intestino delgado. A localização duodenal é, por isso, muito pouco freqüente, possui sintomatologia indefinida e implica conduta terapêutica mais complexa do que quando o tumor se situa em outros segmentos do intestino delgado. Os sintomas mais comuns são dor, náusea, vômito e hemorragia. A presente casuística consiste de 11 neoplasias malignas e sete benignas. Entre as primeiras o adenocarcinoma é o mais freqüente, sendo os lipomas os mais comuns dos neoplasmas benignos. Enquanto nestes a exérese local representa a conduta mais adequada, a duodenopancreatectomia cefálica foi a cirurgia de escolha nos tumores malignos da segunda porção duodenal, exibindo bons resultados. As lesões malignas da terceira porção e principalmente da quarta porção do duodeno foram tratadas pela ressecção duodenojejunal, também com resultados satisfatórios.

    2016-01-01

    Pituitary neoplasias can occur as part of a complex inherited disorder, or more commonly as sporadic (non-familial) disease. Studies of the molecular and genetic mechanisms causing such pituitary tumours have identified dysregulation of >35 genes, with many revealed by studies in mice, rats and zebrafish. Strategies used to generate these animal models have included gene knockout, gene knockin and transgenic over-expression, as well as chemical mutagenesis and drug induction. These animal models provide an important resource for investigation of tissue-specific tumourigenic mechanisms, and evaluations of novel therapies, illustrated by studies into multiple endocrine neoplasia type 1 (MEN1), a hereditary syndrome in which ∼30% of patients develop pituitary adenomas. This review describes animal models of pituitary neoplasia that have been generated, together with some recent advances in gene editing technologies, and an illustration of the use of the Men1 mouse as a pre clinical model for evaluating novel therapies.

    Neoplasms of the thorax encompass those derived from the thoracic wall, trachea, mediastinum, lungs and pleura. They represent a wide variety of lesions including benign and malignant tumors arising from many tissues. The large surface area, 60 to 90 m{sup 2} in man, represented by the respiratory epithelium and associated thoracic structures are ideal targets for carcinogens carried by inspired air. The topic of discussion in this report is the epidemiology, etiology, and mechanisms of spontaneous intrathoracic neoplasia in animals and man. Much of what we know or suspect about thoracic neoplasia in animals has been extrapolated from experimentally-induced neoplasms.

La discusión se centra en un aspecto teórico y otro práctico. El teórico: ¿debe enseñarse cómo funciona la computadora o debe enseñarse simplemente a usarla? El práctico: ¿conviene usar la informática durante las lecciones, o sólo como un complemento extra-clase? Tras consultar a 231 mujeres y hombres dedicados a la enseñanza primaria y secundaria en toda Costa Rica, se encontró que la mayoría está a favor de cómo enseñar a usar la computadora (más que cómo funciona, tanto en el aula como fuera de ella.

Pretende responder a la cuestión de si las directrices que rigen las actuaciones en torno a la lectura de las bibliotecas escolares de Bizkaia, en el País Vasco, son convenientes y fructíferas. Con este objetivo, primero se ha realizado un análisis detallado de los hábitos lectores y las percepciones sobre la importancia de la lectura que tienen los escolares y sobre quién los induce. Posteriormente hemos elaborado un estudio diagnóstico de las bibliotecas de centros de Educación Primaria, analizando su trabajo como agente lector y su integración e implicación con la comunidad educativa. Y finalmente se ha establecido la relación de los dos análisis anteriores para ver hasta qué punto la existencia de una biblioteca escolar favorece o no los hábitos lectores, concluyendo, por una parte, que la actitud y el estímulo familiar son elementos básicos para favorecer los hábitos lectores y, por otra, que la mera presencia de una biblioteca escolar en el centro no es suficiente para mejorar hábitos o valoración de la lectura, sino que la clave está en el tipo de biblioteca que trabaja con los escolares.

    Objective: This study tests an evaluation model with the computed tomography in the local staging of esophageal cancer. Material and Method: This study is longitudinal and retrospective, that it was analyzed three parameters of the interpretation in the computed tomography (linfonodal involvement, border involvement and tumor size) comparing with the pathologic examination after surgery. Results: Thirty-two patients were men (82.05%) and seven were women (17.95%). Computed tomography classified correctly the linfonodal dissemination in 35 cases (89.74%), obtaining 92.0% of sensitivity, 84.61% of specificity and 89.74% of accuracy. When computed tomography analyzed the border involvement, classified correctly 28 of 35 cases, a sensitivity of 78.26% and specificity of 62.5%.

    Results of 52 cases with struma maligna treated with radio-iodine. Between 1966 and 1977, 52 thyroid carcinoma patients received radio-iodine therapy. Their age ranged from 18 to 82 years. Out of 52 patients, 46 underwent surgery with 26 thyrodectomized subtotally and 20 totally so. No surgery was performed in 6 cases since this was refused in 2 cases and inoperable for clinical reasons in 4 cases. Radio-iodine treatment was performed 6 to 10 weeks after operation or 2 to 4 weeks after diagnosis. In 9 cases, additional irradiation therapy was performed on metastases (predominantly in skeleton) at total doses ranging between 2500-7500 R focal dose for palliative reasons. In terms of summary, the authors draw the conclusion that surgical ablation of thyroid tissue as total as possible combined with subsequent radio-iodine treatments till complete destruction of the iodine-storing tissue imposes as the optimum treatment of follicular and papillary thyroid carcinoma.

    Full Text Available Foi realizado um estudo retrospectivo de 14 focos de febre catarral maligna (FCM em bovinos, detectados nos anos de 1999-2011, a partir dos arquivos da Seção Anatomia Patológica da Divisão de Laboratórios Veterinários (DILAVE "Miguel C. Rubino" Montevideo. Foram analisados os dados epidemiológicos, apresentação clínica e lesões macroscópicas e histopatológicas. Para a detecção do herpesvírus ovino tipo 2 (OvHV-2 foi utilizada a técnica de PCR sobre as amostras do sistema nervoso central de bovinos de 12 focos. Os surtos ocorreram principalmente nos meses de primavera e verão, na região norte do país. Em 64% (9/14 dos focos ocorreram episódios individuais da enfermidade, enquanto que os casos coletivos foram 5, nos quais a morbidade e mortalidade oscilaram entre 2% e 5%, sendo a letalidade 100% em todos os relatos. Em 50% dos surtos foi confirmado o contato direto entre bovinos e ovinos, enquanto no restante não havia tal informação. Clinicamente predominaram os sinais de opacidade bilateral da córnea, conjuntivite, secreção nasal e ocular mucopurulenta, assim como a síndrome nervosa. Os achados de necropsia mais frequentes foram opacidade bilateral da córnea e lesões inflamatórias nas mucosas. Os achados histopatológicos caracterizaram-se por panvasculite necrótica sistêmica. Foi possível detectar o agente etiológico por PCR em 5 dos 12 casos analisados.

  18. CD44 in hematological neoplasias.

    Science.gov (United States)

    Hertweck, Magdalena Katharina; Erdfelder, Felix; Kreuzer, Karl-Anton

    2011-05-01

    The CD44 protein family spans a large group of transmembrane glycoproteins acquired by alternative splicing and post-translational modifications. The great heterogeneity in molecular structure is reflected in its various important functions: CD44 mediates (1) interaction between cell and extracellular matrix, (2) signal submission, e.g., by acting as co-receptor for membrane-spanning receptor tyrosine kinases or by association with intracellular molecules initiating several signaling pathways, and (3) anchor function connecting to the cytoskeleton via the ezrin-radixin-moesin protein family. The expression pattern of the different CD44 isoforms display strong variations dependent on cell type, state of activation, and differentiation stage. In hematopoietic cells, CD44 mediates interaction of progenitor cells and bone marrow stroma during hematopoiesis, regulates maturation, and activation-induced cell death in T cells, influences neutrophil and macrophage migration as well as cytokine production, and participates in lymphocyte extravasation and migration. CD44 is involved in development and progress of hematological neoplasias by enhancement of apoptotic resistance, invasiveness, as well as regulation of bone marrow homing, and mobilization of leukemia-initiating cells into the peripheral blood. Thereby altered CD44 expression functions as marker for worse prognosis in most hematological malignancies. Additionally, CD44 expression levels can be used to distinguish between different hematological neoplasias and subtypes. Concerning new treatment strategies, CD44 displays promising potential either by direct targeting of CD44 expressed on the malignant cells or reversing an acquired resistance to primary treatment mediated through altered CD44 expression. The former can be achieved by antibody or hyaluronan-based immunotherapy.

    Intratubular germ cell neoplasia is a precursor lesion for germ cell testicular tumors. It is defined as presence of germ cells with abundant vacuolated cytoplasm and large irregular nuclei with nucleoli within seminiferous tubules. The whole morphologic spectrum of intratubular germinal tumors is discussed. Placental alcaline phosphatase, OCT 3/4 can be demonstrated in majority of the cases. Ultrastructural examination does not play a substantial role in differential diagnosis. Gain of chromosome 12p, which is typical for invasive germ cell tumors is absent in pure intratubular germ cell neoplasia. Spermatogonic arrest and rare reactive changes within seminiferous tubuli have to be distinguished from intratubular germ cell neoplasia.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Rabdomiólise é a lesão do músculo esquelético com liberação dos constituintes da célula para o plasma. Exercício exaustivo e extenuante, especialmente em homens não condicionados, pode resultar em morbidade maior com hiperpotassemia, acidose metabólica, coagulação intravascular disseminada, síndrome do desconforto respiratório agudo e rabdomiólise. Tem sido sugerido que hipertermia maligna, choque térmico e rabdomiólise induzida por exercício são síndromes fortemente relacionadas. O objetivo deste relato é descrever um caso de rabdomiólise fulminante após exercício físico e a correlação do quadro com hipertermia maligna. RELATO DO CASO: Homem de 32 anos apresentou mal estar seguido de síncope após correr 2.350 m em prova de aptidão física. Foi levado ao hospital, evoluiu com insuficiência respiratória, bradiarritmia, hipotensão arterial e parada cardiocirculatória. Foi reanimado, ficou comatoso, com importante rigidez muscular, choque persistente, distúrbio de coagulação, acidose metabólica, hiperpotassemia, evoluindo para óbito em menos de 24 horas. A autópsia revelou edema agudo de pulmão, coagulação intravascular disseminada e insuficiência renal aguda conseqüente a rabdomiólise. CONCLUSÕES: Tem sido sugerido que rabdomiólise induzida por exercício e hipertermia maligna são síndromes fortemente relacionadas. O paciente evoluiu para óbito antes de qualquer investigação específica para hipertermia maligna. No entanto, é importante pesquisar a susceptibilidade para esta síndrome em seus familiares a fim de evitar eventos anestésicos com potencial risco para a vida

    Full Text Available Abstract Multiple Endocrine Neoplasia type 1 (MEN1 is a rare autosomal dominant hereditary cancer syndrome presented mostly by tumours of the parathyroids, endocrine pancreas and anterior pituitary, and characterised by a very high penetrance and an equal sex distribution. It occurs in approximately one in 30,000 individuals. Two different forms, sporadic and familial, have been described. The sporadic form presents with two of the three principal MEN1-related endocrine tumours (parathyroid adenomas, entero-pancreatic tumours and pituitary tumours within a single patient, while the familial form consists of a MEN1 case with at least one first degree relative showing one of the endocrine characterising tumours. Other endocrine and non-endocrine lesions, such as adrenal cortical tumours, carcinoids of the bronchi, gastrointestinal tract and thymus, lipomas, angiofibromas, collagenomas have been described. The responsible gene, MEN1, maps on chromosome 11q13 and encodes a 610 aminoacid nuclear protein, menin, with no sequence homology to other known human proteins. MEN1 syndrome is caused by inactivating mutations of the MEN1 tumour suppressor gene. This gene is probably involved in the regulation of several cell functions such as DNA replication and repair and transcriptional machinery. The combination of clinical and genetic investigations, together with the improving of molecular genetics knowledge of the syndrome, helps in the clinical management of patients. Treatment consists of surgery and/or drug therapy, often in association with radiotherapy or chemotherapy. Currently, DNA testing allows the early identification of germline mutations in asymptomatic gene carriers, to whom routine surveillance (regular biochemical and/or radiological screenings to detect the development of MEN1-associated tumours and lesions is recommended.

    Full Text Available A osteopetrose é uma osteopatia hereditária caracterizada pela deficiência na reabsorção óssea que ocorre por disfunção dos osteoclastos. Com o acúmulo de material osteóide que oblitera o canal medular, ocorre hematopoiese extramedular (hepato-esplenomegalia, obliteração dos forames dos nervos cranianos (cegueira, surdez, paralisias faciais, macrocefalia, protusão da fronte, hipertelorismo, exoftalmo, aumento da pressão intracraniana, retardo na erupção dentária, atraso no crescimento, atraso no desenvolvimento neuropsicomotor, e a morte ocorre precocemente nos primeiros anos de vida. A única alternativa terapêutica curativa é o transplante de medula óssea (TMO de doador HLA idêntico, pois restabelece a hematopoiese e a função monócito-macrófago, com melhora das lesões ósseas e anormalidades hematopoiéticas, embora não reverta as alterações sensoriais já instaladas. Os autores relatam casos de duas crianças portadoras de osteopetrose maligna submetidas ao transplante de medula óssea com sucesso. A primeira encontra-se no dia +1260 do TMO, com melhora evidente da radiologia esquelética, sem progressão das deficiências neurológicas que apresentava, e com biópsia óssea sem sinais de osteopetrose. O segundo paciente encontra-se no dia + 700, com sinais de reabsorção óssea e sem progressão dos danos neurológicos. Os autores chamam a atenção para a necessidade de diagnóstico precoce da osteopetrose e o rápido encaminhamento para o transplante de medula óssea antes da instalação de seqüelas neurológicas definitivas.Osteopetrosis is an inherited disorder characterized by the inability to reabsorb and remodel bone due to osteoclast dysfunction.

    Clinical application of narrow band imaging facilitates diagnosis of esophageal neoplasia. However, no previous investigation has been conducted on magnifying endoscopy combined with narrow band imaging in detection of minimal superficial esophageal neoplasia, which is defined as neoplasia neoplasia. Between January 2005 and November 2011, 53 minimal superficial esophageal neoplasias in 40 patients were diagnosed by screening upper gastrointestinal endoscopy with narrow band imaging at our hospital. We investigated findings including brownish dots, brownish epithelium, and demarcation line of minimal superficial esophageal neoplasia diagnosed histopathologically as low-grade intraepithelial neoplasia, high-grade intraepithelial neoplasia, and squamous cell carcinoma. Significantly more brownish dots (P neoplasia compared with low-grade neoplasia. When minimal superficial esophageal neoplasia was diagnosed as high-grade intraepithelial neoplasia or squamous cell carcinoma, sensitivity, specificity, positive predictive value, and negative predictive value were 88.9, 42.9, 44.4, and 88.2%, respectively, for brownish dots; 94.4, 51.4, 50.0, and 94.7%, respectively, for brownish epithelium; and 66.7, 62.9, 48.0, and 78.6%, respectively, for demarcation line.

    Full Text Available Multiple endocrine neoplasia type I or Wermer syndrome is characterized by primary hyperparathyroidism, enteropancreatic endocrine tumor, and a pituitary pathology. A 35-year-old male presented with visual field defects, hyperprolactinemia, and hypogonadism. He also had multiple infraumbilical skin-colored nodules. A syndromal association of Wermer syndrome was derived using the dermal, pituitary, parathyroid, and gastrointestinal hormonal manifestations of the tumor. The radiological and histological findings of lesion which underwent biopsy are discussed. The presence of collagenomas, lipomas, and hypopigmented macules in a patient with neuroendocrine symptoms should raise the suspicion of an underlying multiple endocrine neoplasia.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A Hipertermia Maligna é doença rara e potencialmente fatal associada à exposição a agentes halogenados e succinilcolina. A mortalidade e morbidade resultante pode ser reduzida pelo diagnóstico precoce e tratamento específico, o que inclui o dantrolene sódico. A população brasileira é de aproximadamente 160 milhões de habitantes assistidos por mais de 6000 anestesiologistas. Na última década, sobretudo, considerável atenção foi dada à esta doença, disto resultando especialistas melhor informados e mais hospitais aparelhados para trata-la. Este estudo visa avaliar o nível atual de informação acerca da Hipertermia Maligna entre os anestesiologistas brasileiros, de sorte a orientar novas iniciativas voltadas para o controle desta afecção. MÉTODO: Vinte questões sobre diagnóstico, prevenção e tratamento da Hipertermia Maligna foram enviadas aos 6164 membros da Sociedade Brasileira de Anestesiologia (SBA. RESULTADOS: Seiscentos e quarenta e seis anestesiologistas (10,4% responderam às questões. Foram obtidas mais de 90% das respostas corretas sobre diagnóstico e tratamento. Por outro lado, aproximadamente 50% das respostas sobre indicação da biópsia muscular e farmacologia do dantrolene estavam erradas. CONCLUSÕES: Os resultados acima refletem nível satisfatório de informação sobre este assunto, indicando alguns relevantes aspectos da doença que merecem atenção adicional. O número de respostas é significativo para avaliação do grau de conhecimento sobre este assunto, mas denota insuficiente motivação. Destes achados conclui-se ser necessário ampliar os esforços de educação continuada, contemplando todo os diferentes tópicos deste importante tema da Anestesiologia.JUSTIFICATIVA Y OBJETIVOS: La Hipertermia Maligna es una enfermedad rara y potencialmente fatal asociada a la exposición de agentes halogenados y succinilcolina.

    2007-04-01

    Full Text Available A apoptose e a proliferação celular possuem uma participação importante na tumorigênese, determinando o crescimento tumoral e consequentemente sua agressividade. O presente estudo teve como objetivo avaliar a ocorrência da apoptose associada a proliferação celular em neoplasias mamárias em cadelas e a elas a evolução clínica do paciente. Setenta animais foram submetidos à exérese cirúrgica do tumor, sendo este submetido ao diagnóstico histopatológico e marcação imuno-histoquímica para caspase-3 e Ki-67. Estes marcadores de apoptose e proliferação celular demonstraram grande expressão nas neoplasias malignas, principalmente nos carcinomas, considerado o mais maligno dos tumores. Estes resultados corroboram os dados da literatura e contribuem para um prognóstico tumoral criterioso que complementa a classificação tumoral existente proporcionando uma melhor e maior sobrevida devido a uma adequação do procedimento terapêutico de cada paciente.

O risco para o desenvolvimento de neoplasia maligna é semelhante a qualquer outro segmento colônico, porém se a ressecção inicial foi devida a câncer, há um significativo aumento na incidência de tumor metacrônico quando comparado à população em geral. A incidência do carcinoma metacrônico colônico é geralmente de 3 a 5%. A recorrência do tumor primário, quando associada à ostomia, pode se manifestar com sangramento ou obstrução. Relatamos três doentes com tumor no sitio da colostomia, sua manifestação clínica e a conduta terapêutica adotada.Carcinomas rarely occur at the site of a colostomy. Colostomies are risk for malignancy, just as in any other portion of the colon. If the initial resection was for cancer, then the risk of metachronous colon adenocarcinoma is significantly higher than for the general population. Metachronous colorectal carcinoma occurs from 0.1 to 3.6 percent of patients who undergo surgery for colorectal carcinoma and the recurrence of the primary bowel malignancy that necessitated the stoma may present with signs of bleeding or obstruction. We report three cases of this rare neoplasia occurring at the site of a colostomy, and we review the literature.

    Full Text Available Background: cervix cancer constitutes the second cause of death worldwide, with new diagnosis each year. Objective: to determine the risk factors of cervical intraepithelial neoplasia in the municipality of Cruces. Methods: it was developed an analytical research with case and control design from November 2013 to November 2014. The group of cases was formed of the 34 women with this diagnosis. There were selected 64 females from the same environment with the same age for the control group. The data obtained by surveys and clinical records reviews were presented in absolute numbers and percentages. It was used Chi-squared test and odd ratio. Results: 52 % of women with neoplasia were less than 25 years old. Significant differences were found which associate neoplasia with early sexual intercourse, sexually transmitted infections by Papilloma virus, Plane genital condyloma, and the use of oral contraceptive pills. Multiple sex partner was a frequent antecedent. Conclusion: risk factors associated to cervical intraepithelial neoplasia in the group of women studied in the Cruces municipality were early sexual intercourse, mainly before 15 years old, multiple sex partner, sexually communicated diseases and the use of oral contraceptive pills for more than 5 years.

    Cabe recordar que a raíz de la promulgación en 1978, se tejieron toda clase de versiones alrededor del significado de la estrategia planteada entonces como un paso fundamental, para un objetivo que parecía inalcanzable. En numerosos debates se hablaba de que se presentaba como una atención elemental de salud, en otros se situaba como el primer contacto de la población con la entidad de salud, en el mejor de los casos se le daba el significado de primera atención, en algunos de atención primordial, en otros de atención básica, no pocos la asimilaban a salud familiar, finalmente cuando se habló en Otawa (Canadá 1986 de la promoción y prevención como fuerzas insustituibles y el Director de la Organización Mundial de la Salud (Mahler 1986 habló de la “reacción favorable frente al fracaso de las acciones anteriores”, tomó fuerza el concepto de atención primaria como el motor insustituible para la promoción y prevención.

The oral cavity is place of 6% of all tumours in dogs, being the sixth most important localization of neoplasias in this specie. The non-odontogenic tumors arise from structures of the oral cavity, except from dental tissue, and they are mostly malignant. Odontogenic tumors are those originated from the dental structures. In the case of tumors of non-odontogenic, will be described the oral papillomatosis, the melanoma, the squamous cell carcinoma, and the fibrosarcoma. Among the odontogenic tumors, the focus will be on the epulides, ameloblastoma, odontoma and dentigerous cysts.

  9. A Left-Sided Prevalence of Lentigo Maligna: A UK Based Observational Study and Review of the Evidence

    Full Text Available Skin cancer has been shown to present asymmetrically, prevalent on the left side of the body, more so in subtypes of cutaneous melanoma such as lentigo maligna. Biases have been linked to cumulative UV light exposure and automobile driving patterns. Though left-right ratios have previously correlated with the side men or women tend to position themselves or countries drive on, more recent trends indicate a consistent left-sided bias. To clarify reasons for changing trends, a review of the evidence base and LM’s laterality in a UK cohort (99 cases 2000–2011 was conducted for the first time. The strong correlation of left-sided excess, found in both genders (ratios 1.381–1.5, P<0.05  X2 0.841, is congruent with more recent findings. Though evidence indicates that driving position is no longer a risk factor for LM, due most likely to improved car window UV protection, it remains the most commonly attributed cause. Understanding phenomena such as UV lights “scatter effect” or that cumulative exposure may not be a significant risk factor helps rationalize older conclusions that would otherwise appear contradictory. The reasons for left-sided excess remain unclear but may be due to factors requiring further research such as the body’s anatomical/embryological asymmetry.

Khyber Institute of Ophthalmic Medical Sciences, Hayatabad Medical Complex, Peshawar, from April 2003 till August 2006. The study included 36 eyes of 35 patients with biopsy-proven ocular surface neoplasia. The details of patients regarding age, gender, laterality and risk factors were entered into a specially-designed proforma. Each patient was also assessed biomicroscopically for type and complications of ocular surface neoplasia. The frequency of OSSN was 0.37 among admitted hospital patients. Among 36 cases of OSSN, squamous cell carcinoma of the conjunctiva was the most common type of OSSN seen in 63.9%, followed by carcinoma in situ of conjunctiva in 25% and carcinoma in situ of cornea in 11.1%. Male patients outnumbered female (65.7% vs 34.3%) with 71.42% of patients above 60 years of age. The risk factors identified were: old age, ultraviolet B exposure and xeroderma pigmentosa. Treatment consisted of local resection with or without adjuvant therapy in 61.1%, exenteration in 30.5%, enucleation in 5.5% and chemo/radiotherapy in 2.7%. Intraocular invasion was seen in 5.5% and orbital spread in 30.5%. The frequency of OSSN was 0.37% among admitted patients. Identification of exact etiological factors will enable to formulate strategies that are likely to decrease the incidence of this disease and the associated morbidity and mortality.

    A retrospective study was conducted to review neoplasia of captive snakes in the Zoo Atlanta collection from 1992 to 2012. Of 255 snakes that underwent necropsy and histopathologic examination at Zoo Atlanta during the study period, 37 were observed with neoplasia at necropsy. In those 37 snakes, 42 neoplastic lesions of 18 primary cell types were diagnosed. Thirty-five of those neoplasms (83.3%) were malignant, and of those, 19 were of mesenchymal origin, whereas 14 were of epithelial origin. The median annual rate of neoplasia at necropsy was 12.5% (interquartile range = 2.8-19.5%) over the 21-yr study period. The mean estimated age at death for snakes with neoplasia was 13.2 yr (range, 1-24 yr). Investigating the incidence and clinical significance of neoplasia in captive snakes is vital for developing effective preventative and treatment regimes.

    Paracoccidioidomycosis is a systemic granulomatous disease caused by fungus, and must be considered in the differential diagnosis of intra-abdominal tumors in endemic areas. We report a rare case of paracoccidioidomycosis in the pancreas. A 45-year-old man was referred to our institution with a 2-mo history of epigastric abdominal pain that was not diet-related, with night sweating, inappetence, weight loss, jaundice, pruritus, choluria, and acholic feces, without signs of sepsis or palpable tumors. Abdominal ultrasonography (US) showed a solid mass of approximately 7 cm × 5.5 cm on the pancreas head. Abdominal computerized tomography showed dilation of the biliary tract, an enlarged pancreas (up to 4.5 in the head region), with dilation of the major pancreatic duct. The patient underwent exploratory laparotomy, and the surgical description consisted of a tumor, measuring 7 to 8 cm with a poorly-defined margin, adhering to posterior planes and mesenteric vessels, showing an enlarged bile duct. External drainage of the biliary tract, Roux-en-Y gastroenteroanastomosis, lymph node excision, and biopsies were performed, but malignant neoplasia was not found. Microscopic analysis showed chronic pancreatitis and a granulomatous chronic inflammatory process in the choledochal lymph node. Acid-alcohol resistant bacillus and fungus screening were negative. Fine-needle aspiration of the pancreas was performed under US guidance. The smear was compatible with infection by Paracoccidioides brasiliensis. We report a rare case of paracoccidioidomycosis simulating a malignant neoplasia in the pancreas head.

  3. Radiological signs of bone infection and neoplasia

    International Nuclear Information System (INIS)

    Gibbs, C.

    1994-01-01

    Infection of equine bone is relatively common but neoplasia is rare. Infective organisms can center bone by direct contamination through penetrating wounds, spreads from adjacent infected structures or via the circulation as a consequence of septicaemic illness. Heamatogenous osteomyelitis is most likely to occur in young foals, but it has been suggested that in conjuction with a compromise in the vascular supply, bacteraemia may be a contributory factor to the pathogenesis of osteomyelitis of the proximal sesamoid bones in adult horses (Wisner et al. 1991). The radiographic changes associated with bone infection and neoplasia are often neither specific nor definitive. This is because bone has only a limited capacity to react to pathological insult, which is either to proliferate or be resorbed. The proportions in which these two processes occur and the resulting radiographic patterns which develop are as likely to be a reflection of the site of the lesion and the anatomy of the bone involved as to the type of disease which causes them. This means that radiological signs of bone disturbance should always be interpreted in conjuction with all other clinical information available

    We assessed the association between psychosocial stress and preinvasive cervical neoplasia development controlling for HR-HPV infection. This case-control study enrolled low-income women receiving family planning services at health department clinics. There were 59 cases with biopsy confirmed HSIL and 163 with low-grade SIL and 160 controls with normal cervical cytology. A modified SLE scale was used to measure stressful events and the perceived impact of the event in the prior 5 years. Unconditional logistic regression was used to assess SIL risk and stressful events scores and by subscales. After adjusting for age, HR-HPV infection, and lifetime number of sex partners, the SLE count score was associated with an increased risk of SIL among white women (aOR = 1.20; 95% CI = 1.04, 1.38) yet not among African American women (aOR = 1.02; 95% CI = 0.87, 1.19). The relationship stress subscale (divorce, infidelity, an increase in the number of arguments, and psychological and physical partner violence) was the only one of four subscales (loss, violence, and financial stress) associated with SIL, again, only among white women (aOR = 1.54; 95% CI = 1.21, 1.96). These data suggest that psychosocial stress may play a role in SIL development. Future studies are needed to confirm these findings, to explore racial difference in reporting stress, and to explore the mechanism through which psychosocial stress may affect cervical neoplasia risk.

    Objectives GLUT-1 has been found to have an important role in the upregulation of various cellular pathways and implicated in neoplastic transformation correlating with biological behavior in malignancies. However, literature regarding the significance of GLUT-1 expression in pancreatic neoplasia has been limited and controversial. Methods Immunohistochemical expression of GLUT-1 was tested in a variety of pancreatic neoplasia including ductal adenocarcinomas (DAs), pancreatic intraepithelial neoplasms (PanINs), intraductal papillary mucinous neoplasms (IPMNs), and serous cystadenomas. Results There was a progressive increase in the expression of GLUT-1 from low- to higher-grade dysplastic lesions: All higher-grade PanINs/IPMNs (the ones with moderate/high-grade dysplasia) revealed noticeable GLUT-1 expression. Among the 94 DAs analyzed, there were minimal/moderate expression in 46 and significant expression in 24 DAs. However, all 4 clear-cell variants of DAs revealed significant GLUT-1 immunolabeling, as did areas of clear-cell change seen in other DAs. Moreover, all 12 serous cystadenomas expressed significant GLUT-1. GLUT-1 expression was also directly correlated with DA histological grade (P = 0.016) and tumor size (P = 0.03). Conclusions GLUT-1 may give rise to the distinctive clear-cell appearance of these tumors by inducing the accumulation of glycogen in the cytoplasm. Additionally, because GLUT-1 expression was related to histological grade and tumor size of DA, further studies are warranted to investigate the association of GLUT-1 with prognosis and tumor progression.

MEN type 1 (MEN1) describes the association of pituitary, parathyroid, and pancreatic islet cell tumors with a variety of many other lesions. MEN type 2 (MEN2) conditions represent at least four different syndromes that associate pheochromocytoma with medullary thyroid carcinoma, hyperparathyroidism, and a number of other manifestations. Other pheochromocytoma-associated syndromes include von Hippel-Lindau disease; neurofibromatosis 1; the recently defined paraganglioma syndromes type 1, 3, and 4; Carney-Stratakis syndrome; and the Carney triad. Carney-Stratakis syndrome is characterized by the association of paragangliomas and familial gastrointestinal stromal tumors. In the Carney triad, patients can manifest gastrointestinal stromal tumors, lung chondroma, paraganglioma, adrenal adenoma and pheochromocytoma, esophageal leiomyoma, and other conditions. The Carney complex is yet another form of MEN that is characterized by skin tumors and pigmented lesions, myxomas, schwannomas, and various endocrine neoplasias. Copyright © 2010 Elsevier Inc.

    Full Text Available Introduction: Dose homogeneity within and dose conformity to the target volume can be a challenge to achieve when treating large area scalp lesions. Traditionally High Dose Rate (HDR brachytherapy (BT scalp moulds have been considered the ultimate conformal therapy. We have developed a new technique, Tangential Volumetric Modulated Arc Therapy (TVMAT that treats with the beam tangential to the surface of the scalp. In the TVMAT plan the collimating jaws protect dose-sensitive tissue in close proximity to the planning target volume (PTV. Not all the PTV is within the beam aperture as defined by the jaws during all the beam-on time. We report the successful treatment of one patient. Methods: A patient with biopsy proven extensive lentigo maligna on the scalp was simulated and three plans were created; one using a HDR brachytherapy surface mould, another using a conventional VMAT technique and a third using our new TVMAT technique. The patient was prescribed 55 Gy in 25 fractions. Plans were optimised so that PTV V100% = 100%. Plans were compared using Dose-Value Histogram (DVH analysis, and homogeneity and conformity indices. Results: BT, VMAT and TVMAT PTV median coverage was 105.51%, 103.46% and 103.62%, with homogeneity index of 0.33, 0.07 and 0.07 and the conformity index of 0.30, 0.69 and 0.83 respectively. The median dose to the left hippocampus was 11.8 Gy, 9.0 Gy and 0.6 Gy and the median dose to the right hippocampus was 12.6 Gy, 9.4 Gy and 0.7 Gy for the BT, VMAT and TVMAT respectively. Overall TVMAT delivered the least doses to the surrounding organs, BT delivered the highest. Conclusions: TVMAT was superior to VMAT which was in turn superior to BT in PTV coverage, conformity and homogeneity and delivery of dose to the surrounding organs at risk. The patient was successfully treated to full dose with TVMAT. TVMAT was verified as being the best amongst the three techniques in a second patient.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A hipertermia maligna (HM é uma desordem farmacogenética da musculatura esquelética, caracterizada por estado hipermetabólico após anestesia com succinilcolina e/ou agentes anestésicos voláteis. Várias síndromes neuromusculares estão associadas com susceptibilidade, no entanto a síndrome de Moebius não é descrita. O dantrolene é o fármaco de escolha para o tratamento. Recrudescência pode ocorrer em até 20% dos casos após o tratamento do evento inicial. RELATO DO CASO: Lactente, masculino, primeiro gemelar, sete meses, 6,5 kg. Portador da síndrome de Moebius. Internado para correção de pé torto congênito. Apresentou HM após exposição à sevoflurano e succinilcolina, prontamente revertida com dantrolene, sendo o fármaco mantido por 24 horas. Dez horas após a interrupção do dantrolene, houve recrudescência da HM, a qual não respondeu satisfatoriamente ao tratamento, evoluindo para óbito. DISCUSSÃO: Doenças musculoesqueléticas em crianças estão associadas a aumento de risco para desenvolvimento de MH, embora a síndrome de Moebius ainda não tenha sido descrita. O dantrolene é fármaco de eleição para o tratamento da síndrome, está indicada profilaxia durante as primeiras 24-48 horas do episódio inicial. Os principais fatores associados à recrudescência são: tipo muscular, longa latência após exposição anestésica e aumento da temperatura. A criança tinha apenas um fator de risco. Este caso nos remete à reflexão de que devemos estar atentos a crianças com doença musculoesquelético e que devemos manter o tratamento durante 48 horas.

    2014-01-01

    Human papillomavirus (HPV) infection is the most common sexually transmitted virus infection; about 40 out of 150 known HPV genotypes have been associated with genitoanal lesions in the female and male. They have been divided into low-risk (LR) and high-risk (HR) HPV types according to the association of each HPV genotype with genitoanal benign warts, genitoanal cancer and precursor lesions. For the most part, genitoanal HPV infection is equally common in men and in women. Genitoanal HPVs are predominantly transmitted by sexual intercourse. In a minor number of individuals where HR HPV infection has persisted, malignant squamous-cell tumors may develop. There are 15 mucosal oncogenic HPV types which are the etiological factor of cervical cancer and other genitoanal cancers. DNAs of HR HPV types are present in 100% of all cervical carcinomas and in 100% of the precursor lesions, the cervical intraepithelial neoplasias 2 and 3. HPV-16 and -18 alone account for 70% of the oncogenic mucosal HPV types identified. HR HPV types, mostly HPV-16 and -18, are the causes of vaginal and vulvar cancers in females, anal cancers in both genders and cancer of the penis in men. While anal cancers are linked to HR HPVs in more than 80% of cases, only 40% of vulvar cancers and 50% of penile cancers are HPV positive. Genitoanal cancers have a similar anatomy, histology and similar risk factors as well as natural histories. About 60% of vulvar and 50% of penile cancers are HPV negative, but associated with chronic inflammatory disorders, mainly lichen sclerosus. Clinical manifestations of LR HPVs in both sexes are genitoanal warts (condylomata acuminata), which are benign highly infectious tumors. The highest rate of warts is observed in females 16-24 years of age. In males the peak is at the age of 20-24 years. Diagnosis of genitoanal warts should exclude other sexually transmitted infections and diseases. A high number of genitoanal dermatoses, benign tumors, malignant squamous

    Hemopoietic neoplasias are unique cancers generally affecting bone marrow, and requires a special attention for disease control and also their complications. When these neoplastic disorders accompany to pregnancy there are many risks both for mother and foetus. Diagnostic difficulties due to the limited use of imaging modalities is essential in pregnant women. On the other hand suboptimal using of the anti-neoplastic drugs and their higher toxicity in mother and foetus must be considered in the management of these neoplastic disorders. Due to the lack of therapeutic guidelines in these cases, team approach is essential and therapy requires to the use the art of medicine. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Since Warburg proposed in 1956 that cancer cells exhibit increased glycolysis due to mitochondrial damage, numerous researchers have assumed that glycolysis is the predominant ATP supplier for cancer cell energy-dependent processes. However, chemotherapeutic strategies using glycolytic inhibitors have been unsuccessful in arresting tumor proliferation indicating that the Warburg hypothesis may not be applicable to all existing neoplasias. This review analyzes recent information on mitochondrial metabolism in several malignant neoplasias emphasizing that, although tumor cells maintain a high glycolytic rate, the principal ATP production may derive from active oxidative phosphorylation. Thus, anti-mitochondrial drug therapy may be an adequate adjuvant strategy to arrest proliferation of oxidative phosphorylation-dependent neoplasias.

    Endothelial cell (EC)-derived neoplasias range from benign hemangioma to aggressive metastatic angiosarcoma, which responds poorly to current treatments and has a very high mortality rate. The development of treatments that are more effective for these disorders will be expedited by insight into the processes that promote abnormal proliferation and malignant transformation of human ECs. The study of primary endothelial malignancy has been limited by the rarity of the disease; however, there is potential for carefully characterized EC lines and animal models to play a central role in the discovery, development and testing of molecular targeted therapies for vascular neoplasias. This review describes molecular alterations that have been identified in EC-derived neoplasias, as well as the processes that underpin the immortalization and tumorigenic conversion of ECs. Human EC lines, established through the introduction of defined genetic elements or by culture of primary tumor tissue, are catalogued and discussed in relation to their relevance as models of vascular neoplasia.

Sin embargo, esa es, una tarea nada sencilla, dado el fuerte carácter idealista de sus principios y postulados. A través de diversos mecanismos, como develar sus antecedentes inmediatos y remotos, la detección de modelos en conflicto, de contradicciones conceptuales y el uso extensivo de preguntas, diversas afirmaciones doctrinarias, que parecen de toda obviedad, son puestas en entredicho. Se invita así al lector/a a una 'deconstrucción' del concepto de Atención Primaria de la Salud, de cara a producir nuevas propuestas más estratégicas y eficaces para que los trabajadores de salud, donde quiera que se desempeñen, cuenten con herramientas para enfrentar la creciente mercantilización del sector.

    Objective: to evaluate, by means of magnetic resonance imaging, the standardized field borders in radiotherapy for malignant neoplasm of uterine cervix, and to determine the role of this method in the reduction of possible planning errors related to the conventional technique. Materials and methods: magnetic resonance imaging studies for planning of treatment of 51 patients with uterine cervix cancer were retrospectively analyzed. The parameters assessed were the anterior and posterior field borders on sagittal section. Results: The anterior field border was inappropriate in 20 (39.2%) patients and geographic miss was observed in 37.3% of cases in the posterior border. The inappropriateness of both field borders did not correlate with clinical parameters such as patients' age, tumor staging, histological type and degree. Conclusion: the evaluation of standardized field borders with the use of magnetic resonance imaging has demonstrated high indices of inappropriateness of the lateral field borders, as well as the relevant role of magnetic resonance imaging in the radiotherapy planning for patients with uterine cervix cancer with a view to reduce the occurrence of geographic miss of the target volume.

    Full Text Available Abstract Background Using new molecular biology techniques, recent studies have implicated a common evolutionary pathway between lobular neoplasia, lobular carcinomas, and columnar cell lesions. Our aims were to assess the frequency of lobular neoplasia in a series of breast biopsies that were performed and examined in the same institution and to analyze the association between subtypes of lobular neoplasia and benign and malignant breast lesions. Methods Cases were selected after reviewing archived pathological reports in the Breast Pathology Laboratory, School of Medicine of Federal University of Minas Gerais (1999-2008. Cases of lobular neoplasia were reviewed and classified as atypical lobular hyperplasia, ductal involvement by cells of atypical lobular hyperplasia, lobular carcinoma in situ, and pleomorphic lobular carcinoma in situ. Coexistence of lobular neoplasia with other breast lesions, including columnar cell lesions, invasive ductal carcinoma and invasive lobular carcinoma, was evaluated. The association between lobular neoplasia and breast lesions was analyzed by Fisher's exact test and chi-square test for linear trend. Results We analyzed 5650 breast specimens, selecting 135 breast specimens (2.4% that had a diagnosis of lobular neoplasia, corresponding to 106 patients. Hematoxylin and eosin-stained slides were available for 84 cases, 5 of which were excluded because they contained only "indeterminate" in situ lesions. Of the 79 remaining cases, columnar cell lesions were present in 78.5%, primarily with columnar cell changes without atypia (67.7%. Invasive carcinoma was present in 45.6% of cases of lobular neoplasia--a similar frequency (47.2% as invasive ductal carcinoma and invasive lobular carcinoma. We noted a significant linear trend (p in situ compared with atypical lobular hyperplasia. Invasive lobular carcinomas were associated with lobular carcinoma in situ in 33% of cases, compared with 2.8% of atypical lobular

    The induction of cancer by ionizing radiation is a matter of great practical importance to the nuclear industry, to national defense, to radiological medicine and to the general public. It is increasingly apparent that carcinogenesis is one of the leading dose-limiting effects of radiation exposure (Co90). Quantitative information at the cellular level is essential to an understanding of the mechanisms of radiogenic neoplastic initiation and the stages of promotion and progression to overt neoplasia. We have developed two experimental models, the rat thyroid and rat mammary clonogen transplant systems, for the quantitative study of radiation carcinogenesis at the cellular level in vivo (C185). The most important steps taken or completed during the current grant year include: (a) demonstration of the high age-dependent radiosensitivity of prepubertal rat mammary clonogens to radiogenic damage which may influence their susceptibility to neoplastic initiation, and (b) demonstration of the feasibility of using a molecular test for clonogenicity in which Simple Sequence Repeats in the DNA serve as identifying signals of the genotypic origin of the cells. We have also (c) set up a large carcinogenesis experiment to test the effect of close intercellular contact in thyroid glands in situ on promotion-progression of radiogenically initiated clonogens, (d) achieved considerable further concentration of thyroid clonogens, and (e) begun to explore whether thyroid cells can be induced to give rise to three dimensional multicellular structures in culture in reconstituted basement membrane. These are discussed in this report

    Full Text Available Anal intraepitelial neoplasia (AIN constitutes a major health problem in certain risk groups, such as patients with immunosuppression of varied origin, males who have sexual relations with other males, and females with a previous history of vaginal or cervical abnormalities in cytology. Its relationship with the human papillomavirus (HPV infection has been well documented; however, many of the factors involved in the progression and regression of the viral infection to dysplasia and anal carcinoma are unknown. AIN can be diagnosed through cytology of the anal canal or biopsy guided by high-resolution anoscopy. However, the need for these techniques in high-risk groups remains controversial. Treatment depends on the risk factors and given the high morbidity and high recurrence rates the utility of the different local treatments is still a subject of debate. Surgical biopsy is justified only in the case of progression suggesting lesions. The role of the vaccination in high-risk patients as primary prevention has been debated by different groups. However, there is no general consensus on its use or on the need for screening this population.

    2014-01-01

    Full Text Available Biliary intraepithelial neoplasia (BilIN is a precursor lesion of hilar/perihilar and extrahepatic cholangiocarcinoma. BilIN represents the process of multistep cholangiocarcinogenesis and is the biliary counterpart of pancreatic intraepithelial neoplasia (PanIN. This study was performed to clarify the histological characteristics of BilIN in relation to PanIN. Using paraffin-embedded tissue sections of surgically resected specimens of cholangiocarcinoma associated with BilIN and pancreatic ductal adenocarcinoma associated with PanIN, immunohistochemical staining was performed using primary antibodies against MUC1, MUC2, MUC5AC, cyclin D1, p21, p53, and S100P. For mucin staining, Alcian blue pH 2.5 was used. Most of the molecules examined here showed similar expression patterns in BilIN and PanIN, in which their expression tended to increase along with the increase in atypia of the epithelial lesions. Significant differences were observed in the increase in mucin production and the expression of S100P in PanIN-1 and the expression of p53 in PanIN-3, when compared with those in BilIN of a corresponding grade. These results suggest that cholangiocarcinoma and pancreatic ductal adenocarcinoma share, at least in part, a common carcinogenic process and further confirm that BilIN can be regarded as the biliary counterpart of PanIN.

    There is an ever growing report of data supporting the evidence that accumulated genetic changes underlie the development of neoplasia. The paradigma of this multistep process is colon cancer were cancer onset is associated, over decades, with at least seven genetic events. The number of genetic alterations increases moving from adenomatous lesions to colon cancer and, although the genetic alterations occur according to a preferred sequence, the total accumulation of changes rather than their sequential order is responsible of tumor biological behavior. It is noteworthy that, at least for this neoplasia, carcinogenesis appears to arise as a result of the mutational activation of oncogenes coupled with the mutational inactivation of tumor suppressor genes. In some cases mutant suppressor genes appear to exert a phenotypic effect even when present in the heterozygous state thus been non "recessive" at the cellular level. The general features of this model may apply also to renal cell cancer (RCC) and prostate cancer (CaP). Extensive literature exists on the cytogenetic and molecular findings in RCC. Only 2% of RCC are familiar, but molecular genetic studies of these cancers have provided important informations on RCC pathogenesis. As with other cancers, familiar RCC is characterized by an early age of onset and frequent multicentricity. A pathological classification useful in studying these patients subdivide renal cancers in papillary (pRCC) and non papillary (RCC) neoplasms. The most common cause of inherited RCC is the Von Hippel Lindau disease (VHL) a dominantly inherited multisystem disorder characterized by retinal and cerebellar hemangioblastomas, pheochromocytomas, pancreatic cysts and RCC. Over 70% of these patients will develop an RCC by their sixth decade. In 1993 the isolation of the tumor suppressor gene in VHL disease at the level of chromosome 3p25-p26 have lead to a better understanding of RCC. Most missense mutations are associated with high risk of

    Pancreatic intraepithelial neoplasia is a precursor to ductal adenocarcinoma of the pancreas that shows gastric differentiation. Pancreatic intraepithelial neoplasia-3 has the highest potential to progress to adenocarcinoma, and its distinction from lower-grade pancreatic intraepithelial neoplasias is important for clinical management. However, morphologic grading of pancreatic intraepithelial neoplasia suffers from significant interobserver variability. A product of cell polarity gene lethal giant larvae 2 is a marker of gastric foveolar epithelium expressed in a basolateral fashion, which is lost or mislocalized in gastric epithelial dysplasia and adenocarcinoma. In this study, we investigated a role of lethal giant larvae 2 expression in differentiating low-grade pancreatic intraepithelial neoplasias, that is, pancreatic intraepithelial neoplasia-1 and pancreatic intraepithelial neoplasia-2, from pancreatic intraepithelial neoplasia-3 and pancreatic ductal adenocarcinoma. The immunohistochemical patterns of lethal giant larvae 2 expression were examined in normal pancreatic ducts, 48 pancreatic intraepithelial neoplasia lesions of all histologic grades, and 91 adenocarcinomas on a tissue microarray or conventional sections. The expression pattern was recorded as basolateral, cytoplasmic, negative, or combinations of any of them. Whereas normal duct epithelia did not exhibit lethal giant larvae immunoreactivity, all but one lesion of low-grade pancreatic intraepithelial neoplasia showed basolateral lethal giant larvae staining. Conversely, all lesions of pancreatic intraepithelial neoplasia-3 and adenocarcinoma showed loss of lethal giant larvae 2 staining and/or its cytoplasmic localization. Interestingly, a basolateral expression was focally seen in 4 adenocarcinomas with a foamy gland pattern and was always admixed with negatively stained areas. In conclusion, our results show that low-grade pancreatic intraepithelial neoplasias express lethal giant larvae 2

    To determine the risk of cutaneous neoplasia following photochemotherapy (PUVA), we reviewed patients with psoriasis treated at out unit between 1979 and 1991. Two hundred and forty-five patients were assessed, with a median duration of follow-up of 9.5 years. Fifty-nine per cent were male, and 41% female. The median number of exposures was 59, and the median total dose was 133J/cm{sup 2} for the group as a whole. Non-melanoma skin cancers (NMSC) occurred in six individuals (2.4%), basal cell carcinoma occurred in all six and one individual also developed four squamous cell carcinomas and Bowen`s disease of the penis. No cases of malignant melanoma were recorded. Patients who developed NMSC received a median number of 225 exposures and a median cumulative dose of 654J/cm{sup 2}. Compared with a control study population in West Glamorgan, Wales, there was a 1.4 (95% confidence limits (CL) 0.5 and 3.1) times increased risk of NMSC. A statistically significant increased incidence of NMSC was found for patients who had received 100 or more exposures, and 250 or more J/cm{sup 2}, with risks of 3.7 (95% CL 1.0 and 9.5), and 4.0 (95% CL 1.1 and 10), respectively. A PUVA dose of < 250 J/cm{sup 2} or < 100 exposures conferred a minimal increase in risk of NMSC in our study population. (author).

    We have developed rat thyroid and mammary clonogen transplantation systems for the study of radiogenic cancer induction at the target cell level in vivo. The epithelial cell populations of both glands contain small subpopulations of cells which are capable of giving rise to monoclonal glandular structures when transplanted and stimulated with appropriate hormones. During the end of the last grant year and the first half of the current grant year, we have completed analyses and summarized for publication: investigations on the relationship between grafted thyroid cell number and the rapidity and degree of reestablishment of the thyroid-hypothalamicpituitary axis in thyroidectomized rats maintained on a normal diet or an iodine deficient diet; studies of the persistence of, and the differentiation potential and functional characteristics of, the TSH- (thyrotropin-) responsive sub-population of clonogens during goitrogenesis, the plateau-phase of goiter growth, and goiter involution; studies of changes in the size of the clonogen sub-population during goitrogenesis, goiter involution and the response to goitrogen rechallenge; and the results of the large carcinogenesis experiment on the nature of the grafted thyroid cell number-dependent suppression of promotion/progression to neoplasia in grafts of radiation-initiated thyroid cells. We are testing new techniques for the culture, cytofluorescent analysis and characterization mammary epithelial cells and of clonogens in a parallel project, and plan to apply similar technology to the thyroid epithelial cells and clonogen population. Data from these studies will be used in the design of future carcinogenesis experiments on neoplastic initiation by high and low LET radiations and on cells interactions during the neoplastic process

    We have developed rat thyroid and mammary clonogen transplantation systems for the study of radiogenic cancer induction at the target cell level in vivo. The epithelial cell populations of both glands contain small subpopulations of cells which are capable of giving rise to monoclonal glandular structures when transplanted and stimulated with appropriate hormones. Previous results indicated that these clonogens are the precursor cells of radiogenic cancer, and that initiation, is common event at the clonegenic cell level. Detailed information on the physiologic control of clonogen proliferation, differentiation, and total numbers is thus essential to an understanding of the carcinogenic process. We report here studies on investigations on the relationships between grafted thyroid cell number and the rapidity and degree of reestablishment of the thyroid-hypothalamus-pituitary feedback axis in thyroidectomized rats maintained on a normal diet or an iodine deficient diet; studies of the persistence of, and the differentiation potential and functional characteristics of, the TSH-(thyrotropin-) responsive sub- population of clonogens during goitrogenesis, the plateau-phase of goiter growth, and goiter involution; studies of changes in the size of the clonogen sub-population during goitrogenesis, goiter involution and the response to goitrogen rechallenge; and a large carcinogenesis experiment on the nature of the grafted thyroid cell number-dependent suppression of promotion/progression to neoplasia in grafts of radiation-initiated thyroid cells.

    Evaluation of patients with Barrett's esophagus (BE) using dye-based chromoendoscopy, optical chromoendoscopy, autofluorescence imaging, or confocal laser endomicroscopy does not significantly increase the number of patients with a diagnosis of early neoplasia compared with high-definition white light endoscopy (HD-WLE) with random biopsy analysis. These newer imaging techniques are not more effective in standard surveillance of patients with BE because the prevalence of early neoplasia is low and HD-WLE with random biopsy analysis detects most cases of neoplasia. The evaluation and treatment of patients with BE and early stage neoplasia should be centralized in tertiary referral centers, where procedures are performed under optimal conditions, by expert endoscopists. Lesions that require resection are almost always detected by HD-WLE, although advanced imaging techniques can detect additional flat lesions. However, these are of limited clinical significance because they are effectively eradicated by ablation therapy. No endoscopic imaging technique can reliably assess submucosal or lymphangio invasion. Endoscopic resection of early stage neoplasia in patients with BE is important for staging and management. Optical chromoendoscopy can also be used to evaluate lesions before endoscopic resection and in follow-up after successful ablation therapy.

A bibliometric analysis of the bibliographic references of the studies published in the journal Atención Primaria during 1991. A data base, managed by dBASE IV, was created. The Unit of Documental Analysis and Bibliometry of the Institute of Documental and Historical Studies in Science (University of Valencia-CSIC). 2,615 bibliographic references in 205 studies contained in volume 8 of Atención Primaria. References from journal articles (68%) and books (26%) predominated. There were a large number of references from Spanish publications (45%) as against Northamerican (27%) and British (15%). There were few references from other European countries or Latin America. Information was quickly out of date (4 year semiperiod; Price index 50%). High proportion of self-quotations from the journal. The major role of the journal Atención Primaria in communicating information in the primary care field was underlined. The small amount of information from Latin America and E.U. countries (except Great Britain) highlights the isolation of Spain from these countries, which can be explained by the limits of the primary care field itself. There was also little use of information to which access was more difficult for primary care doctors, such as doctoral theses, congress papers or reports. Moreover this is a field with a high percentage of recent literature and rapidly out-of-date information.

    Serrated neoplasia of the gastro-intestinal tract have peculiar microscopic and molecular features that are still incompletely described. Some serrated polyps seem to be involved in a new carcinogenic pathway in the colon: the serrated neoplasia pathway, with hypermethylation of the cytosine-guanine dinucleotides, located in the promoter of some genes such as h-MLH1, BRAF and MGMT. The natural history of the serrated polyps and their risk for progression to malignancy are still unclear. There is no official guideline for the management of serrated polyps. The aim of this article is to describe the epidemiological, morphological, immunohistochemical and molecular characteristics of the serrated neoplasia of the gastrointestinal tract: hyperplastic polyps, "traditional" serrated adenomas, mixed hyperplastic and adenomatous polyps, sessile serrated adenomas, hyperplastic polyposis and serrated adenocarcinomas.

  12. Lobular intraepithelial neoplasia arising within breast fibroadenoma

    Science.gov (United States)

    2013-01-01

    Background Fibroadenomas are the second most common breast pathology occurring in young women under the age of 35 years old. Fibroadenomas can be classified as simple or complex according to histological features. Complex fibroadenomas differ from simple fibroadenomas because of the presence of cysts (3 mm), sclerosing adenosis, epithelial calcifications, or papillary apocrine changes. Most fibroadenomas are clinically identifiable. In 25% of cases, fibroadenomas are non-palpable and are diagnosed with mammography and ultrasound. Differential diagnosis with well differentiated breast cancer is often necessary, particularly with medullary or mucinous tumors. Calcification findings within fibroadenomas by mammogram have to be investigated. The age of a lump is usually reflected by calcifications. Microcalcification can hide foci of carcinoma in situ when they are small, branching type, and heterogeneous. However, many morphological possibilities may not be reliable for deciding whether a certain calcification is the product of a malignant or a benign process. From a radiological point of view, fibroadenomas containing foci of carcinoma in situ can be indistinguishable from benign lesions, even if the incidence of carcinoma within fibroadenomas is estimated as 0.1–0.3%, and it could be a long-term risk factor for invasive breast cancer. Case presentation A 44-year-old woman presented with a 1.5-cm palpable, smooth, mobile lump in the lower-inner quadrant of her right breast. Standard mediolateral oblique and craniocaudal mammograms showed a cluster of eccentric popcorn-like calcifications within the fibroadenoma. After lumpectomy, a definitive histological examination confirmed the intra-operative diagnosis of a benign mass. However, lobular intraepithelial neoplasia foci were found, surrounded by atypical lobular hyperplasia. Conclusions The possibility of an old benign breast lump might be supported by fine needle aspiration biopsy or core biopsy before initiating

The aim is to monitor the clinical quality at the national, regional, and hospital departmental levels and serve as a platform for research. Study population: The DCMR has nationwide coverage and contains information on patients diagnosed at hematology departments from January 2010 onward, including patients with essential thrombocythemia, polycythemia vera, myelofibrosis, unclassifiable myeloproliferative neoplasms, chronic myelomonocytic leukemia, and chronic myeloid leukemia. Main variables: Data are collected using standardized registration forms (so far up to four forms per patient, which are consecutively filled out online at time of diagnosis, after 2-year and 5-year follow-ups, and at end of follow-up. The forms include variables that describe clinical/paraclinical assessments, treatment, disease progression, and survival – disease-specific variables – as well as variables that are identical for all chronic myeloid malignancies.

    Fibroadenomas are the second most common breast pathology occurring in young women under the age of 35 years old. Fibroadenomas can be classified as simple or complex according to histological features. Complex fibroadenomas differ from simple fibroadenomas because of the presence of cysts (3 mm), sclerosing adenosis, epithelial calcifications, or papillary apocrine changes. Most fibroadenomas are clinically identifiable. In 25% of cases, fibroadenomas are non-palpable and are diagnosed with mammography and ultrasound. Differential diagnosis with well differentiated breast cancer is often necessary, particularly with medullary or mucinous tumors. Calcification findings within fibroadenomas by mammogram have to be investigated. The age of a lump is usually reflected by calcifications. Microcalcification can hide foci of carcinoma in situ when they are small, branching type, and heterogeneous. However, many morphological possibilities may not be reliable for deciding whether a certain calcification is the product of a malignant or a benign process. From a radiological point of view, fibroadenomas containing foci of carcinoma in situ can be indistinguishable from benign lesions, even if the incidence of carcinoma within fibroadenomas is estimated as 0.1-0.3%, and it could be a long-term risk factor for invasive breast cancer.

    Full Text Available O diagnóstico das lesões císticas pancreáticas pelos métodos de imagem, especialmente as de pequeno tamanho, é cada vez mais freqüente. Em alguns casos, ele representa um dilema em relação à terapêutica, podendo ser pseudocistos inflamatórios, neoplasias primárias ou secundárias. Para a decisão terapêutica, é necessário definir se a neoplasia é benigna, maligna ou potencialmente maligna. Hoje, a ecoendoscopia é considerada o exame padrão-ouro para a investigação do pâncreas, fornecendo dados sobre a morfologia destas lesões e possibilitando, por meio da punção guiada em tempo real, a colheita de material para avaliação citológica e dos marcadores tumorais. Este procedimento é considerado seguro e eficiente e apresenta taxas de sensibilidade e especificidade altas e de morbidade e de complicações baixas. No diagnóstico das lesões mucinosas do pâncreas, os fatores preditivos mais significativos para o diagnóstico diferencial são a presença de septos, os nódulos murais e as alterações parenquimatosas, para o qual as taxas de sensibilidade, especificidade e grau de exatidão são, respectivamente, 94%, 85% e 88%. Os autores têm por objetivo revisar as principais neoplasias císticas primárias do pâncreas, enfatizando a aplicação da ecoendoscopia no diagnóstico definitivo dessas neoplasias.Pancreatic cystic lesions, particularly small lesions, are more easily diagnosed nowadays with the use of imaging methods. In some cases, the diagnosis represents a challenge to establish the treatment, as it can range from inflammatory pseudocysts to primary or metastatic cystic neoplasms. In order to choose the treatment, it is necessary to determine if the lesion is benign, borderline, or malignant. Currently, echoendoscopy is considered the gold standard procedure for pancreatic evaluation as it clearly shows the morphology of the lesion, and also allows the acquisition of pancreatic material for cytological and

Segundo a literatura, são encontradas entre 11% e 52% dos homens infectados pelo HIV, entre 6% a 20% dos homens e 1% a 2,8% das mulheres sem essa infecção. Entre 8,5% e 13% das NIA de alto grau evoluirão para carcinoma invasivo, indicando a necessidade do rastreamento e do seguimento desses doentes para prevenção. Não há tratamento satisfatório com baixos índices de morbidez e a recidiva é comum. Em geral, as formas de tratamento podem de ser divididas em tópicas, entre elas, ácido tricloroacético, podofilina, podofilotoxina, imiquimod, terapia fotodinâmica, e ablativas, ou seja, excisão cirúrgica, ablação pelo LASER, coagulação pelo infravermelho e eletrofulguração. Há, ainda, os que consideram aceitável a conduta expectante. O tratamento tópico se justifica pelo caráter multifocal da lesão e os ablativos têm taxas de complicação e recidiva muito semelhantes. De qualquer forma, doentes com qualquer anormalidade histológica necessitam de seguimento adequado, principalmente com colposcopia e citologia anal.Anal intra-epithelial neoplasia (AIN, provoked by HPV, is considered as an anal cancer precursor.

    Full Text Available El síndrome de Sweet fue descrito en el año 1964 por Robert Douglas Sweet, como una entidad a la cual denominó dermatosis neutrofílica febril y aguda. Se caracteriza por cinco rasgos principales: 1 aparición brusca de placas eritemato-dolorosas en cara, cuello y extremidades; 2 fiebre; 3 leucocitosis polimorfonuclear; 4 denso infiltrado dérmico a predominio neutrofilico; 5 rápida respuesta al tratamiento esteroideo. Se puede clasificar en cinco grupos: idiopático, parainflamatorio, paraneoplásico, secundario a drogas y asociado a embarazo. En el 20% de los casos se asocia a enfermedades malignas, representando las hematológicas el 85% y los tumores sólidos el 15% restante. Se presenta una serie de siete casos de síndrome de Sweet asociado a neoplasias, diagnosticados durante el período 2002-2006, de los cuales seis correspondieron a enfermedades oncohematológicas y el restante a tumores sólidos. Como comentario de dicha casuística, se hace hincapié en la importancia del diagnóstico de este síndrome, debido a que puede anunciar la recaída del tumor o la progresión de la enfermedad de base. De esta manera, mediante el uso de métodos de diagnóstico y tratamiento oportunos, se lograría mejorar la calida de vida de estos pacientes.

    A novel combination of tumors was found in a 68 year-old female with Multiple Endocrine Neoplasia type-1 (MEN 1) that included a cystic pancreatic endocrine neoplasm (CPEN), a pituitary adenoma, and multifocal cholesterol granulomas (MCGs) in the breast, pleura, and the extremities. The pancreatic tumor displayed a single central locule surrounded by a thin rim of neoplastic parenchyma. The tumor showed heterogeneity in the architecture that included glandular, trabecular and solid patterns. The tumor cells of the pancreas were immunohistochemically positive for both endocrine and pancreatic acinar markers including chromogranin A, synaptophysin, glucagon, lipase, and reg protein. Electron microscopy revealed that there were numerous smaller dense-cored neurosecretory granules, larger zymogen-like granules and microvilli on the apical side of the tumor cells. The pancreatic tumor was diagnosed as CPEN with acinar cell features. Analysis of the DNA extracted from the tissues revealed that there is a MEN1 germline mutation in exon 10 codon 527, and somatic mutation in exon 2 codon 32 in the pancreatic tumor, and one base pair deletion in exon 2 codon 79 in the pituitary adenoma. Here, we report the case and discuss possible pathogenesis of CPEN and MCGs in a patient with MEN 1.

    To evaluate the clinical significance of farnesoid X receptor (FXR) in thyroid neoplasia. FXR expression was assessed immunohistochemically on 88 thyroid neoplastic tissues (benign = 44, malignant = 44). Enhanced FXR was more frequently observed in papillary carcinomas compared with hyperplastic nodules (p = 0.0489). In malignant lesions, elevated FXR was associated with capsular (p = 0.0004) and vascular invasion (p = 0.0056) and increased follicular cells' proliferative rate (p < 0.0001). Elevated FXR expression was also associated with larger tumor size (p = 0.0086), presence of lymph node metastases (p = 0.0239) and lymphatic invasion (p = 0.0086) and increased recurrence rate risk (p = 0.0239). FXR may be associated with tumor aggressiveness that affects patients' survival in thyroid neoplasia.

    MicroRNAs (miRNAs) have emerged as a class of powerful gene expression regulators. Acting at the post-transcriptional level, miRNAs modulate the expression of at least one-third of the mRNAs that are encoded by the human genome. The expression of a single gene can be regulated by several miRNAs, and every miRNA has more than one target gene. Thus, the miRNA regulatory circuit, which affects essential cellular functions, is of enormous complexity. Moreover, a fundamental role for miRNAs has been determined in the onset and progression of human cancers. Here, we summarize the main alterations in miRNA expression that have been identified in thyroid neoplasias and examine the mechanisms through which miRNA deregulation might promote thyroid cell transformation. We also discuss how the emerging knowledge on miRNA deregulation could be harnessed for the diagnosis and treatment of thyroid neoplasias.

    The p53 tumor suppressor gene is commonly mutated in colorectal cancer. While the effect of p53 mutations on colorectal cancer prognosis has been heavily studied, less is known about how epidemiologic risk factors relate to p53 status, particularly in early colorectal neoplasia prior to clinically invasive colorectal cancer (including adenomas, carcinoma in situ (CIS), and intramucosal carcinoma). We examined p53 status, as measured by protein overexpression, in 157 cases with early colorectal neoplasia selected from three New York City colonoscopy clinics. After collecting paraffin-embedded tissue blocks, immunohistochemistry was performed using an anti-p53 monoclonal mouse IgG 2 a [BP53-12-1] antibody. We analyzed whether p53 status was different for risk factors for colorectal neoplasia relative to a polyp-free control group (n = 508). p53 overexpression was found in 10.3%, 21.7%, and 34.9%, of adenomatous polyps, CIS, and intramucosal cases, respectively. Over 90% of the tumors with p53 overexpression were located in the distal colon and rectum. Heavy cigarette smoking (30+ years) was associated with cases not overexpressing p53 (OR = 1.8, 95% CI = 1.1–2.9) but not with those cases overexpressing p53 (OR = 1.0, 95% CI = 0.4–2.6). Heavy beer consumption (8+ bottles per week) was associated with cases overexpressing p53 (OR = 4.0, 95% CI = 1.3–12.0) but not with cases without p53 overexpression (OR = 1.6, 95% CI = 0.7–3.7). Our findings that p53 overexpression in early colorectal neoplasia may be positively associated with alcohol intake and inversely associated with cigarette smoking are consistent with those of several studies of p53 expression and invasive cancer, and suggest that there may be relationships of smoking and alcohol with p53 early in the adenoma to carcinoma sequence

    Full Text Available Incremental advances in medical technology, such as the development of sensitive hormonal assays for routine clinical care, are the drivers of medical progress. This principle is exemplified by the creation of the concept of multiple endocrine neoplasia type 2, encompassing medullary thyroid cancer, pheochromocytoma, and primary hyperparathyroidism, which did not emerge before the early 1960s. This review sets out to highlight key achievements, such as joint biochemical and DNA-based screening of individuals at risk of developing multiple endocrine neoplasia type 2, before casting a spotlight on current challenges which include: (i ill-defined upper limits of calcitonin assays for infants and young children, rendering it difficult to implement the biochemical part of the integrated DNA-based/biochemical concept; (ii our increasingly mobile society in which different service providers are caring for one individual at various stages in the disease process. With familial relationships disintegrating as a result of geographic dispersion, information about the history of the origin family may become sketchy or just unavailable. This is when DNA-based gene tests come into play, confirming or excluding an individual's genetic predisposition to multiple endocrine neoplasia type 2 even before there is any biochemical or clinical evidence of the disease. However, the unrivaled molecular genetic progress in multiple endocrine neoplasia type 2 does not come without a price. Screening may uncover unknown gene sequence variants representing either harmless polymorphisms or pathogenic mutations. In this setting, functional characterization of mutant cells in vitro may generate helpful ancillary evidence with regard to the pathogenicity of gene variants in comparison with established mutations.

    The incidence of vulvar intra-epithelial neoplasia (VIN) is increasing in the developed countries especially in young women. There is little consensus regarding the optimal management. Surgery used to be the gold standard. Alternatives to surgery are now needed for the treatment of VIN. Many studies investigated the effectiveness of Imiquimod 5% cream in this pathology. We present a literature review of the results published on the subject. Copyright © 2015. Published by Elsevier SAS.

    This study evaluated the effects of the nonsteroidal antiinflammatory agent piroxicam on chronic radiation proctitis in the rat. Forty female Wistar rats received a 2250-cGy dose of irradiation to the distal 2 cm of the colon. Twenty received piroxicam 8.0 mg/kg orally 30 minutes before exposure and 24 hours after exposure; 20 rats served as irradiated controls. All animals were evaluated by colonoscopy 1 and 3 weeks postexposure and every third week until death or killing at 1 year. At killing, colons were removed for light microscopic examination. One year postirradiation results showed no differences in mortality, vascular changes, acute inflammation, colitis cystica profunda, or rectal stricture between the control and piroxicam-treated groups. However, at 1 year postirradiation the control group demonstrated neoplasia in 15 of 19 animals compared with eight of 20 animals in the piroxicam-treated group. The first endoscopic appearance of colonic neoplasm occurred at 15 weeks postirradiation in one control irradiated rat whereas the first evidence of endoscopic neoplasm in the piroxicam-treated group did not occur until 36 weeks postirradiation. Histologic examination documented a tendency toward a greater presence of adenocarcinomas in the control group compared with the piroxicam-treated group. The authors conclude that piroxicam treatment significantly decreased the incidence of colonic neoplasia in general as well as delayed the endoscopic appearance of colonic neoplasia in rats after pelvic irradiation. 41 references

    The tumors of the kidney are around the 3% of the neoplasia in adult patients and, at the postmortem examination, the renal neoplasias has a frequency of 1/300 for tumors diameter of 1 to 2 cms. In the treatment of the small neoplasias, techniques of nephron sparing and enucleation are used. These techniques have shown the same therapeutic effectiveness of the radical nephrectomy in patients with tumors smaller than 4 centimeters, with reduction of morbidity. However, there are few clinical situation in which the surgery has a high risk: patients with solitary kidney, chronic renal failure, multiple localizations involving also contralateral kidney, in patients with other malignancies and in von Hippel-Lindau Syndrome. Recently, percutaneous mininvasive techniques have been applied (ex. thermoablation): these techniques allow to reduce the duration of general anesthesia, they offer the possibility to use spinal anaesthesia (besides deep sedation and general anaesthesia) with reduction in mortality during surgery. The most commonly used among interstitial therapies is the radiofrequency (RF), which changes electromagnetic waves into heat. RF used both tomography and ultrasound-guided. The latter is the most recommended because it allows to follow the procedure in real-time. The treatment of renal tumors with RF, in which surgery is inadvisable, is safe and effective especially in peripheral and/or exophytic lesions lower than 4 cm. However the larger tumors can also be treated successfully with combined therapy or multiple sessions.

    OBJECTIVE: Several studies have implicated primary sclerosing cholangitis (PSC) as an additional risk factor for colorectal neoplasia in inflammatory bowel disease (IBD). Some reports have indicated that the risk is even higher in PSC-IBD patients after liver transplantation (Ltx), but this issue...... is controversial. We aimed to compare the risk of colorectal neoplasia in PSC-IBD patients before and after Ltx and to identify risk factors for colorectal neoplasia post-transplant. MATERIAL AND METHODS: In a multicenter study within the Nordic Liver Transplant Group, we assessed the risk of colorectal neoplasia......-one (25%) PSC-IBD patients developed colorectal neoplasia. The cumulative risk of colorectal neoplasia was higher after than before Ltx (HR: 1.9, 95% CI: 1.3-2.9, p = 0.002). A multivariate analysis demonstrated aminosalicylates and ursodeoxycholic acid as significantly associated with an increased risk...

    The aim of this study was to reveal whether 3 biomarkers (p16INK4a, ProEx C, and human papilloma virus DNA) are useful in the diagnosis of cervical intraepithelial neoplasia and whether they could predict disease progression of cervical intraepithelial neoplasia-1. We analyzed 252 cervical specimens: nondysplastic mucosa (n = 9), cervical intraepithelial neoplasia (n = 229), and squamous cell carcinoma (n = 14). Immunostaining for p16INK4a and ProEx C, and the hybridcapture II assay for human papilloma virus DNA were performed. Expression of p16INK4a and staining for ProEx C were significantly higher in intraepithelial neoplasia 2/3 (96%-100%) than in nondysplastic mucosa (11%) or intraepithelial neoplasia 1 (40%-53%). Human papilloma virus DNA was detected in 69% of intraepithelial neoplasia-1, 95% of intraepithelial neoplasia-2, and 100% of intraepithelial neoplasia 3. Of 99 patients with intraepithelial neoplasia 1 for whom follow-up data was available, 62 (73%) showed spontaneous regression, 17 (20%) demonstrated persistent low-grade lesion, and 7 (7%) progressed to intraepithelial neoplasia 2/3. Expressions of p16INK4a and staining with ProEx C were significantly higher in the progression group than in the regression group. Testing for p16INK4a and ProEx C was sensitive (86%) and moderately specific (60% and 61%, respectively) in predicting the progression of cervical intraepithelial neoplasia 1. Human papilloma virus DNA testing was highly sensitive (100%) but less specific (37%). In conclusion, this study revealed that p16INK4a and ProEx C are useful biomarkers for the diagnosis of cervical intraepithelial neoplasia, and have potential as predictors of progression of low-grade lesions.

  8. Surgical treatment of pancreatic endocrine tumors in multiple endocrine neoplasia type 1

    Directory of Open Access Journals (Sweden)

    Marcel Cerqueira Cesar Machado

    Full Text Available Surgical approaches to pancreatic endocrine tumors associated with multiple endocrine neoplasia type 1 may differ greatly from those applied to sporadic pancreatic endocrine tumors. Presurgical diagnosis of multiple endocrine neoplasia type 1 is therefore crucial to plan a proper intervention. Of note, hyperparathyroidism/multiple endocrine neoplasia type 1 should be surgically treated before pancreatic endocrine tumors/multiple endocrine neoplasia type 1 resection, apart from insulinoma. Non-functioning pancreatic endocrine tumors/multiple endocrine neoplasia type 1 >1 cm have a high risk of malignancy and should be treated by a pancreatic resection associated with lymphadenectomy. The vast majority of patients with gastrinoma/multiple endocrine neoplasia type 1 present with tumor lesions at the duodenum, so the surgery of choice is subtotal or total pancreatoduodenectomy followed by regional lymphadenectomy. The usual surgical treatment for insulinoma/multiple endocrine neoplasia type 1 is distal pancreatectomy up to the mesenteric vein with or without spleen preservation, associated with enucleation of tumor lesions in the pancreatic head. Surgical procedures for glucagonomas, somatostatinomas, and vipomas/ multiple endocrine neoplasia type 1 are similar to those applied to sporadic pancreatic endocrine tumors. Some of these surgical strategies for pancreatic endocrine tumors/multiple endocrine neoplasia type 1 still remain controversial as to their proper extension and timing. Furthermore, surgical resection of single hepatic metastasis secondary to pancreatic endocrine tumors/multiple endocrine neoplasia type 1 may be curative and even in multiple liver metastases surgical resection is possible. Hepatic trans-arterial chemo-embolization is usually associated with surgical resection. Liver transplantation may be needed for select cases. Finally, pre-surgical clinical and genetic diagnosis of multiple endocrine neoplasia type 1 syndrome and

    Both solar and non-solar exposures associated with occupation and work tasks have been reported as skin carcinogens. In the UK, there are well-established surveillance schemes providing relevant information, including when exposures took place, occupation, location of work and dates of symptom onset and diagnosis. To add to the evidence on work-related skin neoplasia, including causal agents, geographical exposure and time lag between exposure and diagnosis. This study investigated incident case reports of occupational skin disease originating from clinical specialists in dermatology reporting to a UK-wide surveillance scheme (EPIDERM) by analysing case reports of skin neoplasia from 1996 to 2012 in terms of diagnosis, employment, suspected causal agent and symptom onset. The suspected causal agent was 'sun/sunlight/ultraviolet light' in 99% of the reported work-related skin neoplasia cases. Most cases reported (91%) were in males, and the majority (62%) were aged over 65 at the time of reporting. More detailed information on exposure was available for 42% of the cases, with the median time from exposure to symptom onset ranging from 44 (melanoma) to 57 (squamous cell carcinoma) years. Irrespective of diagnostic category, the median duration of exposure to 'sun/sunlight/ultraviolet light' appeared longer where exposures occurred in the UK (range 39-51 years) rather than outside the UK (range 2.5-6.5 years). It is important to provide effective information about skin protection to workers exposed to solar radiation, especially to outdoor workers based outside the UK. © The Author 2014.

    Full Text Available Gestational trophoblastic neoplasia (GTN is a spectrum of diseases including partial and complete hydatidiform moles, placental site trophoblastic tumor, and choriocarcinoma. One of the most important considerations is recognition of the possibility of GTN after molar pregnancy or even normal pregnancy. It is common practice to use chest x-ray for the detection of pulmonary metastasis. Computed tomography imaging of the lungs is ordered if lung lesions are noted on chest x-rays. However, understanding the limitations of chest x-rays is important for detecting smaller pulmonary lesions. We present a patient with GTN and pulmonary metastasis after having received 2 negative chest x-rays.

    Full Text Available Abstract Background The p53 tumor suppressor gene is commonly mutated in colorectal cancer. While the effect of p53 mutations on colorectal cancer prognosis has been heavily studied, less is known about how epidemiologic risk factors relate to p53 status, particularly in early colorectal neoplasia prior to clinically invasive colorectal cancer (including adenomas, carcinoma in situ (CIS, and intramucosal carcinoma. Methods We examined p53 status, as measured by protein overexpression, in 157 cases with early colorectal neoplasia selected from three New York City colonoscopy clinics. After collecting paraffin-embedded tissue blocks, immunohistochemistry was performed using an anti-p53 monoclonal mouse IgG2a [BP53-12-1] antibody. We analyzed whether p53 status was different for risk factors for colorectal neoplasia relative to a polyp-free control group (n = 508. Results p53 overexpression was found in 10.3%, 21.7%, and 34.9%, of adenomatous polyps, CIS, and intramucosal cases, respectively. Over 90% of the tumors with p53 overexpression were located in the distal colon and rectum. Heavy cigarette smoking (30+ years was associated with cases not overexpressing p53 (OR = 1.8, 95% CI = 1.1–2.9 but not with those cases overexpressing p53 (OR = 1.0, 95% CI = 0.4–2.6. Heavy beer consumption (8+ bottles per week was associated with cases overexpressing p53 (OR = 4.0, 95% CI = 1.3–12.0 but not with cases without p53 overexpression (OR = 1.6, 95% CI = 0.7–3.7. Conclusion Our findings that p53 overexpression in early colorectal neoplasia may be positively associated with alcohol intake and inversely associated with cigarette smoking are consistent with those of several studies of p53 expression and invasive cancer, and suggest that there may be relationships of smoking and alcohol with p53 early in the adenoma to carcinoma sequence.

Segundo o DSM-IV, os principais critérios são rigidez muscular grave e temperatura elevada, associadas ao uso de medicação antipsicótica. Foi relatado um caso de paciente com 30 anos manifestando história de transtorno afetivo bipolar, que apresentou sinais e sintomas consistentes com SNM, após três semanas de tratamento com olanzapina. Esse relato visa a discutir o risco da SNM ao uso de antipsicóticos atípicos, bem como a importância de diagnóstico precoce e intervenção imediata.Neuroleptic malignant syndrome (NMS is an idiosyncratic, serious and potentially fatal disorder observed in patients who receive treatment with neuroleptics, typical and atypical, as well as medications with dopaminergic effects. The diagnosis is based on clinical and laboratory criteria and the exclusion of other general medical or psychiatric conditions that could best explain the symptoms. The main criteria according to DSM-IV are severe rigidity and fever associated with the use of antipsychotic medication. We present a case of a 30-year-old female with history of bipolar affective disorder that developed signs and symptoms consistent with NMS after three weeks of treatment with Olanzapine. This case aims to address the risk of NMS associated atypical antipsychotic, as well as the importance of an early diagnosis and immediate intervention.

    Young, Orla

    2012-02-01

    BACKGROUND: This study assessed the presence of oxidative damage and lipid peroxidation in thyroid neoplasia. METHODS: Using tissue microarrays and immunohistochemistry, we assessed levels of DNA damage (8-oxo-dG) and lipid peroxidation (4-HNE) in 71 follicular thyroid adenoma (FTA), 45 papillary thyroid carcinoma (PTC), and 17 follicular thyroid carcinoma (FTC) and matched normal thyroid tissue. RESULTS: Cytoplasmic 8-oxo-dG and 4-HNE expression was significantly higher in FTA, FTC, and PTC tissue compared to matched normal tissue (all p values < .001). Similarly, elevated nuclear levels of 8-oxo-dG were seen in all in FTA, FTC, and PTC tissue compared to matched normal (p values < .07, < .001, < .001, respectively). In contrast, a higher level of 4-HNE expression was detected in normal thyroid tissue compared with matched tumor tissue (p < .001 for all groups). Comparing all 3 groups, 4-HNE levels were higher than 8-oxo-dG levels (p < .001 for all groups) except that cytoplasmic levels of 8-oxo-dG were higher than 4-HNE in all (p < .001). These results were independent of proliferation status. CONCLUSION: High levels of DNA damage and lipid peroxidation in benign and malignant thyroid neoplasia indicates this damage is an early event that may influence disease progression.

    Full Text Available Barrett's esophagus (BE patients are routinely screened for high grade dysplasia (HGD and esophageal adenocarcinoma (EAC through endoscopic screening, during which multiple esophageal tissue samples are removed for histological analysis. We propose a computational method called the multistage clonal expansion for EAC (MSCE-EAC screening model that is used for screening BE patients in silico to evaluate the effects of biopsy sampling, diagnostic sensitivity, and treatment on disease burden. Our framework seamlessly integrates relevant cell-level processes during EAC development with a spatial screening process to provide a clinically relevant model for detecting dysplastic and malignant clones within the crypt-structured BE tissue. With this computational approach, we retain spatio-temporal information about small, unobserved tissue lesions in BE that may remain undetected during biopsy-based screening but could be detected with high-resolution imaging. This allows evaluation of the efficacy and sensitivity of current screening protocols to detect neoplasia (dysplasia and early preclinical EAC in the esophageal lining. We demonstrate the clinical utility of this model by predicting three important clinical outcomes: (1 the probability that small cancers are missed during biopsy-based screening, (2 the potential gains in neoplasia detection probabilities if screening occurred via high-resolution tomographic imaging, and (3 the efficacy of ablative treatments that result in the curative depletion of metaplastic and neoplastic cell populations in BE in terms of the long-term impact on reducing EAC incidence.

    Full Text Available OBJECTIVE: To analyze how scrotal neoplasias have been managed during the past decade and to question possible factors or professions associated to its presence. MATERIALS AND METHODS: We retrospectively evaluated every case reported from 1995 to 2005 at our hospital. We described the clinical scenario, complementary exams, treatments and outcomes. We also tried to verify if there was any risk, predisposing factors or professions that would explain the cancer origin. RESULTS: Six cases were reviewed. Out of these, three patients were truck drivers. Five of them showed restricted lesions without inguinal lymph nodes enlargement. Histologically, six patients presented squamous carcinoma, with two of them having the verrucous type. The median age of patients was 52 years old (31 to 89. The five patients who are still alive had their lesions completely removed with safety margin and primary closure. CONCLUSIONS: We have noticed that the scrotal carcinoma behavior is similar to that of the penis, where removal of the lesion and study of the regional lymph nodes help to increase the patient survival rate. The outstanding fact was that three out of six patients were truck drivers, raising the hypothesis that such profession, maybe due to the contact or attrition with the diesel exhaust expelled by the engine or to sexual promiscuity, would imply in a larger risk of developing this rare neoplasia.

  15. Synchronous high-risk melanoma and lymphoid neoplasia.

    LENUS (Irish Health Repository)

    Cahill, R A

    2012-02-03

    Large population-based studies have shown a significant association between melanoma and lymphoid neoplasia, particularly non-Hodgkin\\'s lymphoma (NHL) and chronic lymphocytic leukaemia (CLL), that is independent of any treatment received for the initial tumour. This study examines the presentation, diagnosis, treatment and progress of three patients who developed advanced melanoma concurrently with a lymphoid neoplasm (one NHL, two CLLs), in order to illustrate their association, discuss common aetiological factors and examine possible therapeutic options. As it is the melanoma rather than the lymphoid neoplasm that represents the bigger threat to overall survival, initial treatment should be targeted towards this cancer. However, because of the interplay between the diseases and the possible side-effects of the various treatments, the choice of adjuvant therapy requires careful consideration. Immunosuppression associated with chemotherapy may permit a more aggressive course for the melanoma, while locoregional radiotherapy is contraindicated following lymph node dissections. As immunotherapy is of benefit in the treatment of melanoma and has also been recently shown to be effective in the management of lymphoid neoplasia, we instituted interferon-alpha as adjuvant therapy for these patients, thereby utilizing a single agent to treat the dual pathologies. The three patients have now been followed-up for 6 months without evidence of disease recurrence or progression.

    To perform an initial assessment of the potential of using the gas discharge visualization (GDV) technique to identify patients with colon neoplasias. The GDV camera (also known as the electrophotonic imaging camera) was used to assess the participants. Colonoscopy was performed on all 78 participants, followed by a GDV scan. The control group consisted of 22 people. An endoscopic examination identified colon tumors in the remaining 56 participants. Participant ages ranged from 45 to 86 years (mean, 64.6 ± 1.2 years). The study analyzed GDV images of each patient's fingers, presenting a whole-body view, as well as separate sectors corresponding to the organs in question. There was a significant number of differences between the control group and the patients with colon tumors. The dynamic of the parameters was examined as the level of tumor dysplasia (neoplasia) varied. The values of the following parameters decreased in the control group as compared to the patients with cancerous polyps: normalized luminescence area, internal noise, contour radius, and average luminescence intensity. The values of the following parameters increased in the control group: radius of the inscribed circle, contour line length, area of luminescence, contour line fractality, contour line entropy, and form coefficients. This pilot study demonstrated a statistical difference between the GDV parameters of patients with colon tumors and the control group. These findings warrant a more in-depth study of the potential for GDV technique in screening programs.

    Background: There is a direct correlation between glycemic load and the risk of developing many malignant neoplasms. Aims: The aim of this study was to determine the plasma glucose levels in women with cervical cancer. Methods: The study included 177 women with anatomopathologically diagnosed uterine cervical cancer (stages 0–IV) treated between 1980 and 2008 at the Gynecology and Obstetrics outpatient service of the UFTM, Brazil. The plasma glucose levels of all patients were assayed at the time of diagnosis and correlated with tumor staging. Results: We statistically compared the plasma glucose levels of group 1 (cervical intraepithelial neoplasia 2–3), group 2 (stage I–II), group 3 (stage III–IV), and group 4 (control group: leiomyomas). Patient groups with poor prognosis (groups 2 and 3) showed significantly higher plasma glucose levels (P 90 mg/dl showed CIN versus I/II: P = 0.0753; OR = 2.018; (95% CI: 0.9236 to 4.410) and CIN versus III/IV: P = 0.0975; OR = 2.400; (95% CI: 0.8335 to 6.911). Conclusion: We observed an association between high plasma glucose levels and cervical cancer cases with poor prognoses. Plasma glucose tests should be routinely used as additional prognostic parameters in patients with cervical neoplasias. PMID:21603242

    Research Highlights: Human papillomaviruses cause anal intraepithelial neoplasia (AIN). Digital image processing was carried out to classify the grades of AIN quantitatively. The fractal dimension as well as grey value statistics was calculated. Higher grades of AIN yielded higher values of the fractal dimension. An automatic detection system is feasible. - Abstract: It is well known that human papillomaviruses (HPV) induce a variety of tumorous lesions of the skin. HPV-subtypes also cause premalignant lesions which are termed anal intraepithelial neoplasia (AIN). The clinical classification of AIN is of growing interest in clinical practice, due to increasing HPV infection rates throughout human population. The common classification approach is based on subjective inspections of histological slices of anal tissues with all the drawbacks of depending on the status and individual variances of the trained pathologists. Therefore, a nonlinear quantitative classification method including the calculation of the fractal dimension and first order as well as second order image statistical parameters was developed. The absolute values of these quantitative parameters reflected the distinct grades of AIN very well. The quantitative approach has the potential to decrease classification errors significantly and it could be used as a widely applied screening technique.

    To compare the dietary habits between colorectal neoplasia patients, their first-degree relatives, and unrelated controls. From July 2008 to April 2011, we collected epidemiological data relevant to colorectal cancer from patients with colorectal neoplasias, their first-degree relatives, and also from a control group consisting of people referred for colonoscopy with a negative family history of colorectal cancer and without evidence of neoplasia after colonoscopic examination. The first-degree relatives were divided into two groups following the colonoscopic examination: (1) patients with neoplasia or (2) patients without neoplasia. Dietary habits of all groups were compared. A χ (2) test was used to assess the association between two dichotomous categorical variables. The study groups consisted of 242 patients with colorectal neoplasias (143 men, 99 women; mean age: 64 ± 12 years) and 160 first-degree relatives (66 men, 94 women; mean age: 48 ± 11 years). Fifty-five of the first-degree relatives were found to have a neoplastic lesion upon colonoscopy, while the remaining 105 were without neoplasia. The control group contained 123 individuals with a negative family history for neoplastic lesions (66 men, 57 women; mean age: 54 ± 12 years). Two hypotheses were tested. In the first, the dietary habits of first-degree relatives with neoplasia were more similar to those of patients with neoplasia, while the dietary habits of first-degree relatives without neoplasia were similar to those of the control group. In the second, no sex-related differences in dietary habits were expected between the particular groups. Indeed, no significant differences were observed in the dietary habits between the groups of patients, controls and first-degree relatives with/without neoplastic lesions. Nevertheless, statistically significant sex-related differences were observed in all groups, wherein women had healthier dietary habits than men. In all groups examined, women had

    To evaluate the diagnostic value of peritoneal fluid (PF) cytology for clinical diagnosis of abdominal neoplasia in horses. Ten horses with histopathologically confirmed abdominal neoplasia, in which a PF analysis was performed, were included in this retrospective study. PF was analyzed for total protein concentration and a nucleated cell count was performed. Using cytological criteria of malignancy, the PF samples were evaluated regarding their probability of malignancy. Cytologic classification of cells according to criteria of malignancy allowed a positive cytologic diagnosis of neoplasia in 5 out of 10 peritoneal fluid samples. Malignant lymphoma was the most commonly diagnosed neoplasia (3/10) and could be identified by cytology in 2/3 cases. In 1/2 horses with plasma cell myeloma neoplastic cells were similarly found. Malignant melanoma (2/10) was diagnosed using cytology in one case (presence of melanin-containing cells). Cytological diagnosis of malignant neoplasia was established in the only horse with gastric squamous cell carcinoma, but the morphology of the identified tumour cells did not allow a specific diagnosis. Thus, a definitive diagnosis was achieved in 4/5 horses with proven abdominal neoplasia. The horses with adenocarcinoma (1/10) and haemangiosarcoma (1/10) had no evidence of neoplasia based on cytological findings. No relationship between total protein concentration or the nucleated cell count with the histolopathological diagnosis of abdominal neoplasia was found. Abnormal mitotic figures were considered of greater diagnostic value than the overall mitotic rate. The implementation of nuclear criteria of malignancy in the cytologic evaluation of PF samples allows the identification of neoplastic cells to an acceptable degree. For this purpose, the knowledge of the highly variable morphological features of mesothelial cells is essential. The absence of malignant cells does not rule out abdominal neoplasia. PF cytology should be considered as

    Early neoplasia in Barrett's esophagus (BE) is difficult to detect. Volumetric laser endomicroscopy (VLE) incorporates optical coherence tomography, providing a circumferential scan of the esophageal wall layers. The attenuation coefficient (μVLE) quantifies decay of detected backscattered light versus depth, and could potentially improve BE neoplasia detection. The aim is to investigate feasibility of μVLE for identification of early BE neoplasia. In vivo and ex vivo VLE scans with histological correlation from BE patients ± neoplasia were used. Quantification by μVLE was performed manually on areas of interest (AoIs) to differentiate neoplasia from nondysplastic (ND)BE. From ex vivo VLE scans from 16 patients (13 with neoplasia), 68 AoIs were analyzed. Median μVLE values (mm-1) were 3.7 [2.1 to 4.4 interquartile range (IQR)] for NDBE and 4.0 (2.5 to 4.9 IQR) for neoplasia, not statistically different (p=0.82). Fourteen in vivo scans were used: nine from neoplastic and five from NDBE patients. Median μVLE values were 1.8 (1.5 to 2.6 IQR) for NDBE and 2.1 (1.9 to 2.6 IQR) for neoplasia, with no statistically significant difference (p=0.37). In conclusion, there was no significant difference in μVLE values in VLE scans from early neoplasia versus NDBE. Future studies with a larger sample size should explore other quantitative methods for detection of neoplasia during BE surveillance.

    Identification of colonoscopic features which increase colitis-associated neoplasia risk in patients with ulcerative colitis (UC) may allow patient risk stratification. Our objective was to investigate whether colonoscopic features correlate with the risk of developing colitis-associated neoplasia in patients with UC on surveillance. In this retrospective case-control study, patients with UC who underwent surveillance colonoscopies from 1998 to 2011 were included. Patients with UC with neoplasia were compared with a matched control group of patients with UC without neoplasia in a 1:3 ratio. A total of 111 eligible patients with UC with colon neoplasia were compared with 356 patients with UC without colon neoplasia. On univariate analysis, colitis-associated neoplasia was associated with male gender (odds ratio [OR] = 2.58, 95% confidence interval [CI]: 1.71-3.89, P ≤ 0.001) and smoking history (OR = 1.62, 95% CI: 1.1-2.39, P = 0.045) but not with colonoscopic features, including tubular colon/shortened colon, scarring, segment of severe inflammation, inflammatory polyps, colonic stricture, or macroscopically normal appearance colonoscopy. In multivariate analysis, only male gender (OR = 2.68, 95% CI: 1.77-4.08, P ≤ 0.001) was found to be associated with an increased risk, whereas the use of 5-aminosalicylates was associated with a decreased risk for colitis-associated neoplasia (OR = 0.51, 95% CI: 0.31-0.84, P = 0.009). In patients with UC, colonoscopic features especially on standard-definition white-light colonoscopy did not appear to reliably predict the development of colitis-associated neoplasia. This will leave room for image-enhanced endoscopy technology and molecular markers for the early and accurate detection of colitis-associated neoplasia.

    Objective: To compare radiographic findings and determine useful criteria to differentiate between intranasal neoplasia and chronic rhinitis in cats. Design: Retrospective study. Animals: Cats with chronic nasal disease caused by neoplasia (n = 18) or by chronic rhinitis (n = 11). Procedure: Radiographs were reviewed by 3 radiologists, followed by group review. Diagnosis was determined by intranasal biopsy or necropsy, and specimens were reviewed by a pathologist to confirm cause and histologic diagnosis. Results: Lymphosarcoma was the most common (n = 5) of the 6 histopathologic types in the neoplasia group. Cats in the neoplasia and chronic rhinitis groups had a high prevalence of aggressive radiographic lesions. Prevalence of a facial mass in cats with neoplasia (8/18) versus in those with chronic rhinitis (4/11) and of deviation (9/18 vs 6/11, respectively) or lysis (12/18 vs 7/11) of the nasal septum was similar. However, significantly (P = 0.02) more cats with neoplasia than with chronic rhinitis (13/16 vs 3/7, respectively) had unilateral turbinate destruction/lysis. Additionally, unilateral lateral bone erosion and loss of teeth associated with adjacent intranasal disease were more prevalent in cats with neoplasia (7/8 and 5/18, respectively) than in cats with chronic rhinitis (1/3 and 0/11, respectively). Clinical Implications: Features that may assist in radiographic diagnosis of neoplasia include the appearance of unilateral aggressive lesions, such as lysis of lateral bones, nasal turbinate destruction, and loss of teeth. Bilaterally symmetric lesions are more suggestive of chronic rhinitis than of neoplasia

    Full Text Available La informatización de la atención primaria de salud se percibe como un problema que se soluciona creando redes computarizadas entre los consultorios y policlínicos. El artículo brinda una visión panorámica del estado en que se encuentra el arte de la informatización de la atención primaria y la medicina general integral, en el mundo y en Cuba. Para ello, se sintetiza el origen prehistórico de ese nivel de atención y de la especialidad, así como el desarrollo contemporáneo de la informática y sus aplicaciones médicas; se define igualmente la atención primaria y su informática; se resumen los sistemas de información, las aplicaciones informáticas y sus desafíos; y se ofrece una visión práctica de la historia clínica-electrónica: corazón de la informática de atención primaria de salud y medicina general integral. Se concluye que Cuba ha trabajado 20 años informatizando la dispensarización y estadísticas para la gerencia de servicios de este nivel de atención, pero que también podría trabajar con el enfoque centrado en la vida del paciente, que contribuiría a crear una clasificación integradora de la salud con la enfermedad, y a computarizar la información y la toma de decisiones clínicas en el consultorio del médico, y en el futuro hasta en el hogar del paciente, elevando directamente la calidad de la atención primaria de salud.

    We reviewed the literature about entero-pancreatic neuroendocrine tumors in Multiple Endocrine Neoplasia type 1 syndrome (MEN1) to clarify their demographic features, localization imaging, practice, and appropriate therapeutical strategies, analyzing the current approach to entero-pancreatic neuroendocrine tumors in MEN1. Despite the fact that hyperparathyroidism is usually the first manifestation of MEN1, the penetrance of these tumors is similar. They are characterized by multiplicity of lesions, variable expression of the tumors, and propensity for malignant degeneration. Both the histological type and the size of MEN1 neuroendocrine tumors correlate with malignancy. Monitoring of pancreatic peptides and use of imaging exams allow early diagnosis and prompt surgical treatment, resulting in prevention of metastatic disease and improvement of long-term survival. Surgery is often the treatment of choice for MEN1-neuroendocrine tumors. The rationale for surgical approach is to curtail malignant progression of the disease, and to cure the associated biochemical syndrome, should it be present.

    Full Text Available Primary hyperparathyroidism may occur as a part of an inherited syndrome in a combination with pancreatic endocrine tumours and/or pituitary adenoma, which is classified as Multiple Endocrine Neoplasia type 1 (MEN-1. This syndrome is caused by a germline mutation in MEN-1 gene encoding a tumour-suppressor protein, menin. Primary hyperparathyroidism is the most frequent clinical presentation of MEN-1, which usually appears in the second decade of life as an asymptomatic hypercalcemia and progresses through the next decades. The most frequent clinical presentation of MEN-1-associated primary hyperparathyroidism is bone demineralisation and recurrent kidney stones rarely followed by chronic kidney disease. The aim of this paper is to present the pathomechanism, screening procedures, diagnosis, and management of primary hyperparathyroidism in the MEN-1 syndrome. It also summarises the recent advances in the pharmacological therapy with a new group of drugs—calcimimetics.

    The question of thyroid neoplasia following high-dose radiation treatment to the neck and mediastinum for malignant neoplasms such as Hodgkin's lymphoma in children and young adults has been raised recently. Five patients, 19 to 39 years old, were operated on for thyroid neoplasms that developed following cervical and mediastinal radiation therapy for Hodgkin's lymphoma. Three patients had papillary carcinomas and two had follicular adenomas. The latency period between radiation exposure and the diagnosis of thyroid neoplasm ranged from eight to 16 years. This limited series provided strong support for the recommendation that children and young adults who are to receive high-dose radiation therapy to the head, neck, and mediastinum should receive suppressive doses of thyroxine prior to radiation therapy in order to suppress thyrotropin (thyroid-stimulating hormone) and then be maintained on a regimen of suppression permanently

    In the last decades, cytogenetic and molecular characterizations of hematological disorders at diagnosis and followup have been most valuable for guiding therapeutic decisions and prognosis. Genetic and epigenetic alterations detected by different procedures have been associated to different cancer types and are considered important indicators for disease classification, differential diagnosis, prognosis, response, and individualization of therapy. The search for new biomarkers has been revolutionized by high-throughput technologies. At this point, it seems that we have overcome technological barriers, but we are still far from sorting the biological puzzle. Evidence based on translational research is required for validating novel genetic and epigenetic markers for routine clinical practice. We herein discuss the importance of genetic abnormalities and their molecular pathways in acute myeloid leukemia, myelodysplastic syndromes, and myeloproliferative neoplasms. We also discuss how novel genomic abnormalities may interact and reassess concepts and classifications of myeloid neoplasias. PMID:23056961

    In 2008, the concept of the monosomal karyotype (MK) in adult acute myeloid leukemia (AML) patients was introduced, defined by the presence of a chromosomal aberration pattern characterized by the presence of at least two autosomal monosomies or of one monosomy plus one or more structural aberrations (not including loss of a chromosome). We present a systematic review of the literature about the influence of the MK on the outcome of patients affected by myeloid malignancies (AML, myelodysplastic syndromes, and primary myelofibrosis). For this review, a comprehensive literature search using the term "monosomal karyotype" was performed, considering articles listed in MEDLINE. This analysis of the literature confirms the negative prognostic impact on survival of the MK in myeloid neoplasias. The detrimental effect of MK on AML patients' outcome is independent of other variables, including adverse cytogenetic features, supporting the identification of this entity as a challenging subgroup of patients with distinct biologic and clinical features.

    Neuroendocrine neoplasias (NEN) comprise heterogeneous epithelial neoplasms with a large variety of clinical presentations, treatment options and outcomes. Since potentially all NEN bear malignant potential it is important for long-term clinical management and improvement of outcome to decide on successful and oncologically and economically meaningful follow-up strategies. Evidence-based outcome data validating specific follow-up strategies are, however, not available to date and thus outcome data, known prognostic factors and clinical experience guide the decisions on follow-up regimens. The review summarizes general recommendations as well as specific considerations based on tumor entities, clinicopathological tumor characteristics and clinical experience. Follow-up shall serve the patient to improve outcome, benefit from more effective therapies and suffer less from unnecessary and/or toxic therapeutic interventions and finally preserve or gain a good quality of life.

    2014-01-01

    Angiosarcomas are rare aggressive neoplasms of vascular endothelial origin with a high metastatic rate and poor prognosis. Involvement of the bone marrow by the angiosarcoma is exceedingly uncommon, and there have only been a few cases reported in the literature to date. Clinical manifestations and common laboratory findings of bone marrow involvement can mimic other more common bone marrow-replacing neoplasias such as lymphomas and acute leukemia. A definitive diagnosis is difficult to make from cytologic material, probably due to an associated bone marrow fibrosis, and requires bone marrow trephine biopsy with an immunohistochemical profile. Here we had the opportunity to study a case of metastatic angiosarcoma with positive cytologic findings and an unusual presentation that challenged its primary diagnosis. PMID:24847252

    Full Text Available Primary mesenchymal tumors of the thyroid gland are extremely rare. The authors report a case of primary thyroid osteosarcoma in a male patient presenting a tumoral mass in the neck. CT scan demonstrated a large tumor in the right thyroid lobe with areas of calcification. The surgical specimen consisted of a hard brown-gray tumor, measuring 13 × 11 × 7.5 cm. Microscopy revealed a high-grade malignant neoplasm composed of polygonal cells of intermediate size, chondroid pattern in some areas and osteoid formation. The process was immunonegative for AE1/AE3, glial fibrillary acidic protein (GFAP, epithelial membrane antigen (EMA, p53 and thyroid transcription factor-1 (TTF-1, and immunopositive for CD99 and S100. Thus the diagnosis of primary osteosarcoma of the thyroid gland was established.Tumores mesenquimais da glândula tireoide são extremamente raros.

  2. Rare circulating microRNAs as biomarkers of colorectal neoplasia.

    Directory of Open Access Journals (Sweden)

    Scott V Adams

    Full Text Available MicroRNAs (miRNAs are regulatory RNAs, stable in circulation, and implicated in colorectal cancer (CRC etiology and progression. Therefore they are promising as early detection biomarkers of colorectal neoplasia. However, many circulating miRNAs are highly expressed in blood cells, and therefore may not be specific to colorectal neoplasia.We selected 7 miRNA candidates with previously reported elevated expression in adenoma tissue but low expression in blood cells ("rare" miRNAs, 2 previously proposed as adenoma biomarkers, and 3 implicated in CRC. We conducted a colonoscopy-based case-control study including 48 polyp-free controls, 43 advanced adenomas, 73 non-advanced adenomas, and 8 CRC cases. miRNAs from plasma were quantified by qRT-PCR. Correlations between miRNA expression levels, adjusted for age and sex, were assessed. We used polytomous logistic regression to estimate odds ratios (ORs and 95% confidence intervals quantifying the association between expression levels of miRNAs and case groups. We also conducted nonparametric receiver operating characteristic (ROC analyses and estimated area under the curve (AUC.miRNAs with high expression levels were statistically significantly correlated with one another. No miRNAs were significantly associated with non-advanced or advanced adenomas. Strong (ORs >5 and significant associations with CRC were observed for 6 miRNA candidates, with corresponding AUCs significantly >0.5.These candidate miRNAs, assayed by qRT-PCR, are probably unsuitable as blood-based adenoma biomarkers. Strong associations between miRNAs and CRC were observed, but primarily with miRNAs highly expressed in blood cells. These results suggest that rare miRNAs will require new detection methods to serve as circulating biomarkers of adenomas.

    Colorectal cancer is the second leading cause of death from cancer in the United States. To facilitate the efficiency of colorectal cancer screening, there is a need to stratify risk for colorectal cancer among the 90% of US residents who are considered "average risk." In this article, we investigate such risk stratification rules for advanced colorectal neoplasia (colorectal cancer and advanced, precancerous polyps). We use a recently completed large cohort study of subjects who underwent a first screening colonoscopy. Logistic regression models have been used in the literature to estimate the risk of advanced colorectal neoplasia based on quantifiable risk factors. However, logistic regression may be prone to overfitting and instability in variable selection. Since most of the risk factors in our study have several categories, it was tempting to collapse these categories into fewer risk groups. We propose a penalized logistic regression method that automatically and simultaneously selects variables, groups categories, and estimates their coefficients by penalizing the [Formula: see text]-norm of both the coefficients and their differences. Hence, it encourages sparsity in the categories, i.e. grouping of the categories, and sparsity in the variables, i.e. variable selection. We apply the penalized logistic regression method to our data. The important variables are selected, with close categories simultaneously grouped, by penalized regression models with and without the interactions terms. The models are validated with 10-fold cross-validation. The receiver operating characteristic curves of the penalized regression models dominate the receiver operating characteristic curve of naive logistic regressions, indicating a superior discriminative performance. © The Author(s) 2013.

    AIM: To investigate risk factors and adverse events related to high-dose diazepam administration during endoscopic submucosal dissection for gastric neoplasias. METHODS: Between February 2002 and December 2009, a total of 286 patients with gastric epithelial neoplasia underwent endoscopic submucosal dissection in our hospital. To achieve moderate sedation, 5-7.5 mg of diazepam was administered intravenously by non-anesthesiologists. Intermittent additional administration of 2.5-5 mg diazepam was performed if uncontrollable body movement of the patient was observed. All patients were classified into groups based on the required diazepam dose: low-dose (≤ 17.5 mg, n = 252) and high-dose (> 17.5 mg, n = 79). RESULTS: Differences between the low- and high-dose diazepam groups were observed in lifetime alcohol consumption (0.30 ± 0.48 vs 0.44 ± 0.52 tons, P = 0.032), body weight (58.4 ± 10.3 vs 62.0 ± 9.9 kg, P = 0.006), tumor size (15 ± 10 vs 23 ± 18 mm, P < 0.001), lesion location (P < 0.001) and the presence of ulcerative findings (14/238 vs 18/61, P < 0.001). Multivariate analysis identified all five variables as independently related to required diazepam dosage. In terms of adverse reactions to diazepam administration, paradoxical excitement was significantly more frequent in the high-dose diazepam group (P < 0.001). CONCLUSION: Intermittent administration of diazepam enabled safe completion of gastric endoscopic submucosal dissection except in patients who were alcohol abusers or obese, or who showed complicated lesions.

    Endoscopic resection has proven highly effective and safe in the removal of focal early neoplastic lesions in Barrett's esophagus and is considered the cornerstone of endoscopic treatment. Several techniques are available for endoscopic resection in Barrett's esophagus. The most widely used technique for piecemeal resection of early Barrett's neoplasia is the ligate-and-cut technique. Newer techniques such as endoscopic submucosal dissection may also play a role in the treatment of neoplastic Barrett's esophagus. Treatment of early Barrett's neoplasia should be centralized and limited to expert centers with a high-volume load and sufficient expertise in the detection and treatment of esophageal neoplasia.

    Turmer syndrome (TS) patients show increased morbidity due to metabolic, autoimmune and cardiovascular disorders. A risk of neoplasia is also reported. Here, we review the prevalence of neoplasia in a cohort of Turner patients. We retrospectively evaluated 87 TS women. Follow-up included periodic ultrasound of the neck, abdominal and pelvic organs, dermatologic evaluation and fecal occult blood test. Karyotype was 45,X in 46 patients. During follow-up, 63 girls were treated with growth hormone, 65 with estro-progestin replacement therapy and 20 with L-thyroxine. Autoimmune diseases were present in 29 TS. A total of 17 neoplasms in 14 out of 87 patients were found. Six skin neoplasia, 3 central nervous system tumors, 3 gonadal neoplasia, 2 breast tumors, 1 hepatocarcinoma, 1 carcinoma of the pancreas and 1 follicular thyroid cancer were detected. Age at tumor diagnosis was higher in 45,X pts than in those with other karyotypes (p = 0.003). Adenomioma gallbladdder (AG) was detected in 15.3% of the patients, with a lower age in girls at diagnosis with an associated neoplasia in comparison with TS without tumors (p = 0.017). No correlation between genetic make up, treatment, associated autoimmune diseases and neoplastia was found. In our TS population an increased neoplasia prevalence was reported. A high prevalence of AG was also noted and it might be indicative of a predisposition to neoplasia. Further studies are needed to define the overall risk for neoplasia, and to determine the role of the loss of the X-chromosome and hormonal therapies. Copyright © 2016 Elsevier Masson SAS.

    Although sarcopenia is associated with an increased risk for mortality after the curative resection of colorectal cancer, its influence on the development of advanced colonic neoplasia remains unclear. This study included 1270 subjects aged 40 years or older evaluated with first-time screening colonoscopy at Seoul National University Boramae Health Care Center from January 2010 to February 2015. Skeletal muscle mass was measured with a body composition analyzer (direct segmental multifrequency bioelectrical impedance analysis method). Multiple logistic regression analysis was performed to determine whether sarcopenia is associated with advanced colorectal neoplasia. Of 1270 subjects, 139 (10.9%) were categorized into the sarcopenia group and 1131 (89.1%) into the non-sarcopenia group. In the non-sarcopenia group, 55 subjects (4.9%) had advanced colorectal neoplasia. However, in the sarcopenia group, 19 subjects (13.7%) had advanced colorectal neoplasia, including 1 subject with invasive colorectal cancer (0.7%). In addition, subjects with sarcopenia had a higher prevalence of advanced adenoma (P sarcopenia. According to the multiple logistic regression analysis adjusted for variable confounders, age (odds ratio 1.062, 95% confidence interval 1.032-1.093; P sarcopenia (odds ratio 2.347, 95% confidence interval 1.311-4.202; P = 0.004) were associated with an advanced colorectal neoplasia. Sarcopenia is associated with an increased risk of advanced colorectal neoplasia.

    The authors previously reported that the white opaque substance (WOS) in gastric epithelial neoplasia was caused by accumulation of lipid droplets by immunohistochemical and immunoelectron microscopic studies of adipophilin, which was recently identified and validated as a marker of lipid droplets. The aim of the current study was to investigate the characteristics of the histologic differentiation and mucin phenotype in WOS-positive gastric epithelial neoplasias. A total of 130 gastric epithelial neoplasias (45 adenomas and 85 early adenocarcinomas) from 120 patients were retrospectively evaluated. The presence or absence of WOS was evaluated by M-NBI. Lipids were examined by immunohistochemical staining for adipophilin. Tissue phenotypes were immunohistochemically classified as intestinal (I), gastrointestinal (GI), and gastric (G) using antibodies against CD10, MUC2, MUC5AC and MUC6. The histologic differentiation and mucin phenotype of WOS-positive neoplasias were characterized and examined according to adipophilin expression. The presence of WOS by M-NBI was correlated with histologic differences between adenoma or differentiated type adenocarcinoma and mixed type or undifferentiated type adenocarcinoma (P = 0.0153). Adipophilin was only expressed in primary adenoma and well to moderately differentiated adenocarcinoma components but not in undifferentiated components. WOS and adipophilin expression were only observed in neoplasias with I or GI phenotypes, but not in those with the G phenotype (P neoplasias might indicate differentiation into a mature histological subtype with GI or I mucin phenotype.

    MicroRNA (miRNA) alterations are likely to contribute to the development of pancreatic cancer and may serve as markers for the early detection of pancreatic neoplasia. To identify the miRNA alterations that arise during the development of pancreatic cancer, we determined the levels of 735 miRNAs in 34 pancreatic intraepithelial neoplasias (PanIN) and 15 normal pancreatic duct samples isolated by laser capture microdissection using TaqMan miRNA microarrays. Differential expression of selected miRNAs was confirmed by FISH analysis and by quantitative real-time reverse transcription PCR (qRT-PCR) analysis of selected candidate miRNAs in an independent set of PanIN and normal duct samples. We identified 107 aberrantly expressed miRNAs in different PanIN grades compared with normal pancreatic duct samples and 35 aberrantly expressed miRNAs in PanIN-3 lesions compared with normal pancreatic duct samples. These differentially expressed miRNAs included those that have been previously identified as differentially expressed in pancreatic ductal adenocarcinomas (PDAC; including miR-21, miR-200a/b/c, miR-216a/b, miR-217, miR-146a, miR-155, miR-182, miR-196b, miR-203, miR-222, miR-338-3p, miR-486-3p, etc.) as well as miRNAs not previously described as differentially expressed in these lesions (miR-125b, miR-296-5p, miR-183*, miR-603, miR-625/*, miR-708, etc.). miR-196b was the most selectively differentially expressed miRNA in PanIN-3 lesions. Many miRNAs undergo aberrant expression in PanIN lesions and are likely to be important in the development of PDAC. The miRNAs, such as miR-196b, whose expression is limited to PanIN-3 lesions or pancreatic cancers could be useful as diagnostic markers. ©2011 AACR.

    OBJECTIVE.: Our objective was to compare by response rate the therapeutic options of loop electrosurgical excision procedure (LEEP), laser therapy, and wide local excision in managing high-grade vulvar intraepithelial neoplasia in a pilot study for a randomized clinical trial. MATERIALS AND METHODS.: Between 1995 and 1999, 109 patients presenting with vulvar lesions were registered at a comprehensive cancer center and 2 associated colposcopy clinics. From these 109, we identified 74 patients with lesions histologically proven to be vulvar intraepithelial neoplasia who underwent treatment with CO2 laser, wide local excision, or LEEP. Clinical and pathological features were reviewed retrospectively. Wilcoxon rank sum test and life table analyses were used to compare groups. Response rates for this retrospective study will be used to calculate the sample size for a prospective clinical trial. RESULTS.: Our population was similar to others reported in the literature in age, range of diagnoses, and follow-up. Only 1 of 74 patients (1%) had invasive cancer. In a subset of 62 patients treated for the first time, LEEP and wide local excision were equal in their ability to achieve complete response. Laser ablation was the least successful of all methods (10/20 with laser, 3/20 with LEEP, and 2/22 with wide local excision experienced recurrences [p = .04]). No statistically significant differences among the 3 were noted in time to recurrence (p = .24). Age, age at first intercourse, and number of sexual partners were not correlated with recurrence and did not confound the results. Using a chi approximation, an alpha error of 0.05, and a power of 0.80, researchers should enroll 25 patients per arm if improvement over standard therapy is expected to be 40%, 45 if expected to be 30%, and 95 if expected to be 20%. CONCLUSIONS.: Because of differences in recurrence rate and length of hospital stay and indications of potential differences in cost found in this pilot, LEEP merits

    Background Clinical studies demonstrate increased prevalence of human papillomavirus (HPV)-associated disease in HIV-infected individuals and an increased risk of HIV acquisition in HPV-infected individuals. The mechanisms underlying this synergy are not defined. We hypothesize that women with cervical intraepithelial neoplasia (CIN) will exhibit changes in soluble mucosal immunity that may promote HPV persistence and facilitate HIV infection. Methods The concentrations of immune mediators and endogenous anti-Escherichia coli activity in genital tract secretions collected by cervicovaginal lavage were compared in HIV-negative women with high-risk HPV-positive (HRHPV+) CIN-3 (n = 37), HRHPV+ CIN-1 (n = 12), or PAP-negative control subjects (n = 57). Results Compared with control subjects, women with CIN-3 or CIN-1 displayed significantly higher levels of proinflammatory cytokines including interleukin (IL)-1α, IL-1β, and IL-8 (P < 0.002) and significantly lower levels of anti-inflammatory mediators and antimicrobial peptides, including IL-1 receptor antagonist, secretory leukocyte protease inhibitor (P < 0.01), and human β defensins 2 and 3 (P < 0.02). There was no significant difference in endogenous anti-E. coli activity after controlling for age and sample storage time. Conclusion HRHPV+ CIN is characterized by changes in soluble mucosal immunity that could contribute to HPV persistence. The observed mucosal inflammation suggests a mechanism that may also contribute to the epidemiologic link between persistent HPV and HIV. PMID:22801340

    To describe a case of testicular neoplasia and alopecia universalis in a dog, and successful treatment of the latter with ciclosporin. Twelve-year-old intact male wirehaired fox terrier. Castration, skin biopsy for histopathology, lymphocyte immunophenotyping and clonality analysis of the canine T-cell receptor gamma locus (TCRγ) rearrangement. The dog presented with symmetrical generalized alopecia. Testicular enlargement was noted which on castration was determined to be caused by bilateral interstitial cell tumours, Sertoli cell tumours and a unilateral seminoma. During the four months after castration the alopecia became more severe and widespread. Histopathology of the skin showed moderate, multifocal, mural folliculitis, peribulbar mucinosis and lymphocytic bulbitis, and targeting of anagen hair follicles. Immunophenotyping of the infiltrate showed a population of well-differentiated, small CD3-positive T lymphocytes, some expressing CD4 and others CD8. Molecular analysis revealed a polyclonal lymphocytic infiltrate, substantiating the diagnosis of alopecia areata rather than lymphoma. Treatment with ciclosporin (4.6 mg/kg) and ketoconazole (4.6 mg/kg) resulted in complete hair regrowth. Ciclosporin treatment, in combination with ketoconazole, can be effective for treatment of alopecia universalis in the dog. Alopecia universalis may present with clinically noninflammatory, symmetrical, generalized alopecia, mimicking an endocrine alopecia, and skin biopsies are needed to confirm the diagnosis. © 2016 ESVD and ACVD.

    We reviewed MRI studies of 60 patients presenting with extradural compressive myeloradiculopathy secondary to vertebral disease to assess the imaging features which may help in differentiating tuberculous from neoplastic disease. Spin-echo T1-, proton density- and T2-weighted images were available for all patients and fast low-angle shot images with a low flip angle for 21 patients. Contrast-enhanced images were available for 28 patients. There were 41 patients with tuberculosis and 19 patients with neoplastic disease (metastases 11, lymphoma 6, plasmacytoma 1, and giant cell tumour 1). Discovertebral disease with or without involvement of the posterior arch was a feature not only of tuberculous spondylitis (30 patients) but also of metastases (6). The remaining 11 patients with tuberculosis had ''atypical'' involvement (vertebral body with or without posterior arch in 8 and posterior arch alone in 3) described as typical of neoplasms. This ''typical'' involvement was seen in metastases (5), lymphoma (6) and the 2 primary bone tumours. The presence of an abscess helped in differentiating tuberculosis from neoplasia in 22 of the 41 patients with tuberculosis and was absent in all with neoplasms. The presence of bone fragments in 16 patients (8 with and 8 without an abscess) was found to be specific for tuberculosis. In the absence of an abscess or bone fragments, image-guided biopsy is essential to establish the diagnosis. (orig.). With 9 figs., 2 tabs

    Neoplastic conditions associated with gastrointestinal (GI) tract are common worldwide with colorectal cancer alone accounting for the third leading rate of cancer incidence. Other GI malignancies such as esophageal carcinoma have shown an increasing trend in the last few years. The poor survival statistics of these fatal cancer diseases highlight the need for multiple alternative treatment options along with effective prophylactic strategies. Worldwide geographical variation in cancer incidence indicates a correlation between dietary habits and cancer risk. Epidemiological studies have suggested that populations with high intake of certain dietary agents in their regular meals have lower cancer rates. Thus, an impressive embodiment of evidence supports the concept that dietary factors are key modulators of cancer including those of GI origin. Preclinical studies on animal models of carcinogenesis have reflected the pharmacological significance of certain dietary agents called as nutraceuticals in the chemoprevention of GI neoplasia. These include stilbenes (from red grapes and red wine), isoflavones (from soy), carotenoids (from tomatoes), curcuminoids (from spice turmeric), catechins (from green tea), and various other small plant metabolites (from fruits, vegetables, and cereals). Pleiotropic action mechanisms have been reported for these diet-derived chemopreventive agents to retard, block, or reverse carcinogenesis. This review presents a prophylactic approach to primary prevention of GI cancers by highlighting the translational potential of plant-derived nutraceuticals from epidemiological, laboratory, and clinical studies, for the better management of these cancers through consumption of nutraceutical rich diets and their intervention in cancer therapeutics.

    2017-01-01

    To describe 2 cases of invasive squamous cell carcinoma that originated in the setting of severe atopic keratoconjunctivitis (AKC). Case one involved a 73-year-old male with atopic eczema and severe AKC who developed a limbal lesion suspicious for ocular surface squamous neoplasia (OSSN). Slit-lamp examination was significant for a new sessile lesion in the temporal limbal region of the left eye. The lesion was treated with excisional biopsy and cryotherapy. Topical therapy with mitomycin C, topical interferon alpha 2b, and topical 5-fluorouracil provided only partial control. Exenteration was eventually needed. Case two involved a 53-year-old male with history of severe AKC and eczema. Computed tomography imaging showed an infiltrative mass of the right orbit. Incisional biopsies confirmed conjunctival squamous cell carcinoma of both sides (invasive in the right eye, in situ in the left eye). Exenteration was needed for control of invasive carcinoma in the right eye. Squamous cell carcinoma was treated without success in spite of surgical excision and aggressive treatment with multiple topical agents and multiple applications of cryotherapy. Orbital exenteration was needed in both cases. Chronic inflammation associated with AKC may be a risk factor for the development of bilateral, diffuse, invasive, and recurrent OSSN that may require exenteration.

    Immune profiles have been obtained on 206 individuals including 57 controls, 50 lung cancer patients, and 99 uranium miners with well-defined sputum cytologies ranging from normal to carcinoma in situ. Little effect of smoking, uranium mining or a combination of mining plus smoking on immune function was observed if sputum cytology was normal. In heavy smokers there was a suggestion that total T cells are increased while T cell function is slightly depressed. Immunologic abnormalities were noted in the moderate atypia group where 40% had one or more abnormal immunologic parameters. Immunologic abnormalities were detected in 68 to 70 patients with marked atypia, carcinoma in situ, or invasive carcinoma. Further sequential study of the uranium miner population is necessary to define more precisely the predictive value of immunologic testing, and the role of early identification of high risk individuals in the early institution of definitive therapy, such as surgery or immunotherapy. Long-term prospective analysis of this population may also provide the answer to the question of whether alterations in immune function precede, or result from the appearance of cells committed to the development of neoplasia

    To evaluate the efficacy of color Doppler ultrasound (US) in the diagnosis of gestational trophoblastic neoplasia (GTN). Intralesional color flows and resistive index (RI) on color Doppler US were prospectively analyzed in 21 consecutive suspected GTN cases. RI of the intralesional artery was investigated on the basis of the presence or absence of mass and metastasis. Correlation between RI of intralesional artery and urinary β-hCG was also investigated. Intralesional color flows were identified in 15 patients with GTN. On operation, intralesional color flows were observed in one of two patients in whom the presence of completely necrotic tissue was confirmed. Intralesional color flows, however, were not detected in four patients who were proved not to be GTN sufferers. Sensitivity, specificity, accuracy, positive and negative predictive values, and accuracy were 100%, 83%, 95%, 94% and 100%, respectively. Significant correlation between RI of the intralesional artery and urinary β-hCG was not established (p=0.49, r=0.19). RI of this artery was not substantially different between groups with and without mass, and between groups with and without metastasis (p=0.32, p=0.82). The current study demonstrates that color Doppler US is a sensitive and useful method for the diagnosis of GTN

    A low intake of vegetables (but not fruit) is established as a risk factor for colon cancer. Although there are a multitude of active agents that may explain this, one important candidate is folate. Among studies specifically examining intake of folate derived from food and supplements, higher intake is generally associated with lower risk of both adenomas and cancer. Other nutrients associated with the folate pathway-methionine, vitamin B-6, vitamin B-12-or that impact the pathway-alcohol-have also been shown to influence risk in predictable ways. Polymorphisms in enzymes involved in the metabolism of folate also are associated with modification in risk, but essentially only in the presence of low intakes of folate and related nutrients. The consistency of the above evidence suggests that folate is an active agent, not just a marker for the intake of other effectors found in vegetables and multivitamin preparations. There are at least two mechanisms that may explain these findings: folate is central both to the provision of S-adenosylmethionine, the universal methyl donor, and to the provision of nucleotides for DNA synthesis and repair. Fortification of food with folate, as well as intake from multivitamin and pharmacological sources, may increasingly contribute to the primary prevention of colorectal neoplasia although it is possible that there is such a condition as having too much folate.

    Esophageal cancer is one of the leading causes of cancer-related death and is associated with high morbidity and mortality. It carries a poor prognosis as more than half of patients present with advanced and unresectable disease. One contributing factor is the increased risk of lymph node metastases at early stages of disease. As such, it is essential to detect squamous cell neoplasia (SCN) at an early stage. In order to risk stratify lesions, endoscopists must be able to perform image enhanced endoscopy including magnification and Lugol’s chromoendoscopy. The assessment of both the horizontal extent and depth of any lesion is also of utmost importance prior to treatment. Endoscopic mucosal resection and submucosal dissection remain the standard of care with literature supportive their respective use. Radiofrequency ablation and other endoscopic treatments are currently available although should not be considered first line at this time. Our objective is to review the current options for the endoscopic diagnosis and treatment of esophageal SCN. PMID:28979708

    Full Text Available Os tumores localizados em região de cabeça e pescoço apresentam alta incidência em nosso meio, principalmente se associados com fatores etiológicos ligados aos hábitos de etilismo e tabagismo. Estes mesmos hábitos relacionam-se também com a incidência de câncer em esôfago. Assim sendo, é de se esperar que estes pacientes venham a apresentar outra neoplasia primária neste último órgão. Foi realizado estudo prospectivo com 60 pacientes portadores de câncer em mucosa da região de cabeça e pescoço na Disciplina de Cirurgia de Cabeça e Pescoço e no Serviço de Endoscopia Digestiva do Gastrocentro - UNICAMP, com o objetivo de diagnosticar neoplasias malignas superficiais no esôfago, caracterizadas como segundo tumor primário, e displasias. A endoscopia digestiva alta foi indicada utilizando-se a solução de lugol a 2%, para coloração do epitélio esofagiano, evidenciando-se em 33 pacientes (55%, 42 áreas iodo-claras (suspeitas de neoplasias, que foram submetidas a biopsias para estudo anatomopatológico. Foram diagnosticados cinco carcinomas superficiais de esôfago (8,3%, sendo que três deles eram intra-epiteliais -- in situ (5,0% e cinco áreas de displasia (8,3%. Concluiu-se que o método de coloração da mucosa esofagiana com a solução de lugol a 2%, através da endoscopia digestiva alta, apresenta alta sensibilidade e baixa especificidade para o diagnóstico de um segundo tumor primário e de displasia, em pacientes portadores de carcinoma em mucosa de região de cabeça e pescoço.

    Background: Several animal models for human ulcerative colitis (UC) associated neoplasia have been reported. However, most neoplasias developed in these models have morphological and genetic characteristics different from UC associated neoplasia. Aims: To establish a new colitis associated neoplasia model in p53 deficient mice by treatment with dextran sulphate sodium (DSS). Methods: DSS colitis was induced in homozygous p53 deficient mice (p53−/−-DSS), heterozygous p53 deficient mice (p53+/−-DSS) and wild-type mice (p53+/+-DSS) by treatment with 4% DSS. Numbers of developed neoplasias were compared among the experimental groups, and macroscopic and microscopic features of the neoplasias were analysed. Furthermore, K-ras mutation and beta-catenin expression were assessed. Results: p53−/−-DSS mice showed 100% incidence of neoplasias whereas the incidences in p53+/−-DSS and p53+/+-DSS mice were 46.2% and 13.3%, respectively. No neoplasias were observed in the control groups. The mean numbers of total neoplasias per mouse were 5.0 (p53−/−-DSS), 0.62 (p53+/−-DSS), and 0.2 (p53+/+-DSS). The number of neoplasias per mouse in the p53−/−-DSS group was significantly higher than that in the other DSS groups. The incidences of superficial type neoplasias were 91.7% in p53−/−-DSS mice, 75.0% in p53+/−-DSS mice, and 33.3% in p53+/+-DSS mice. The K-ras mutation was not detected in any of the neoplasias tested. Translocation of beta-catenin from the cell membrane to the cytoplasm or nucleus was observed in 19 of 23 (82.6%) neoplasias. Conclusions: The p53−/−-DSS mice is an excellent animal model of UC associated neoplasia because the morphological features and molecular genetics are similar to those of UC associated neoplasia. Therefore, this model will contribute to the analysis of tumorigenesis related to human UC associated neoplasia and the development of chemopreventive agents. PMID:15082590

    The earliest recognizable stages of breast neoplasia are lesions that represent a heterogeneous collection of epithelial proliferations currently classified based on morphology. Their role in the development of breast cancer is not well understood but insight into the critical events at this early stage will improve efforts in breast cancer detection and prevention. These microscopic lesions are technically difficult to study so very little is known about their molecular alterations. To characterize the transcriptional changes of early breast neoplasia, we sequenced 3'- end enriched RNAseq libraries from formalin-fixed paraffin-embedded tissue of early neoplasia samples and matched normal breast and carcinoma samples from 25 patients. We find that gene expression patterns within early neoplasias are distinct from both normal and breast cancer patterns and identify a pattern of pro-oncogenic changes, including elevated transcription of ERBB2, FOXA1, and GATA3 at this early stage. We validate these findings on a second independent gene expression profile data set generated by whole transcriptome sequencing. Measurements of protein expression by immunohistochemistry on an independent set of early neoplasias confirms that ER pathway regulators FOXA1 and GATA3, as well as ER itself, are consistently upregulated at this early stage. The early neoplasia samples also demonstrate coordinated changes in long non-coding RNA expression and microenvironment stromal gene expression patterns. This study is the first examination of global gene expression in early breast neoplasia, and the genes identified here represent candidate participants in the earliest molecular events in the development of breast cancer.

  4. Lobular neoplasia - borderline type of lesion - risk of subsequent development of invasive lobular carcinoma of the breast, 13 years after excision of radial scar with multifocal lobular neoplasia

    2010-01-01

    Background. Lobular neoplasia is a hyperplastic breast lesion - a borderline type of lesion with a high risk of subsequent development of invasive carcinoma. In case of radial scar diagnosis the risk of invasive carcinoma increases twice in comparison with healthy patients population while in the case of lobular neoplasia diagnosis within radial scar this risk increases 8 to 10 times. Basing on the presented case we analyse and review the literature regarding the clinical, radiological and pathological aspects of lobular neoplasia of the breast. Case report. A 67-yeas old patient was hospitalised in 1995 in order to consult the results of mammography, which revealed a radial scar lesion of the right breast. The patient was then referred to undergo wide local excision. Pathological examination showed dysplastic changes of the radial scar type with 1 cm multifocal lobular neoplasia. The patient was systematically followed clinically and radiologically during the decade 1996-2006 and all examination results were normal. In 2008, an ill-defined nodule appeared within the scar on mammography examination. This was categorized as BI-RADS 4C. The mammotomic biopsy performed under ultrasonography control revealed invasive lobular carcinoma. The tumor was totally locally excised and the sentinel node was histologically verified. The histopathological examination revealed a 1.6 cm focus of invasive lobular carcinoma and the sentinel node was negative. Conclusion. Patients with detected lobular neoplasia should be treated as a risk group of invasive breast cancer development (30-40% vs 10% in a healthy population during the entire life period). Systematic clinical and radiological follow-up should be mandatory. (authors)

    Full Text Available Abstract Background We introduce Approximate Entropy as a mathematical method of analysis for microarray data. Approximate entropy is applied here as a method to classify the complex gene expression patterns resultant of a clinical sample set. Since Entropy is a measure of disorder in a system, we believe that by choosing genes which display minimum entropy in normal controls and maximum entropy in the cancerous sample set we will be able to distinguish those genes which display the greatest variability in the cancerous set. Here we describe a method of utilizing Approximate Sample Entropy (ApSE analysis to identify genes of interest with the highest probability of producing an accurate, predictive, classification model from our data set. Results In the development of a diagnostic gene-expression profile for cervical intraepithelial neoplasia (CIN and squamous cell carcinoma of the cervix, we identified 208 genes which are unchanging in all normal tissue samples, yet exhibit a random pattern indicative of the genetic instability and heterogeneity of malignant cells. This may be measured in terms of the ApSE when compared to normal tissue. We have validated 10 of these genes on 10 Normal and 20 cancer and CIN3 samples. We report that the predictive value of the sample entropy calculation for these 10 genes of interest is promising (75% sensitivity, 80% specificity for prediction of cervical cancer over CIN3. Conclusion The success of the Approximate Sample Entropy approach in discerning alterations in complexity from biological system with such relatively small sample set, and extracting biologically relevant genes of interest hold great promise.

    PTEN is one of the most frequently mutated genes in human cancers. The frequency of PTEN alterations is particularly high in endometrial carcinomas. Loss of PTEN leads to dysregulation of cell division, and promotes the accumulation of cell cycle complexes such as cyclin D1-CDK4/6, which is an important feature of the tumour phenotype. Cell cycle proteins have been presented as key targets in the treatment of the pathogenesis of cancer, and several CDK inhibitors have been developed as a strategy to generate new anticancer drugs. Palbociclib (PD-332991) specifically inhibits CDK4/6, and it has been approved for use in metastatic breast cancer in combination with letrazole. Here, we used a tamoxifen-inducible Pten knockout mouse model to assess the antitumour effects of cyclin D1 knockout and CDK4/6 inhibition by palbociclib on endometrial tumours. Interestingly, both cyclin D1 deficiency and palbociclib treatment triggered shrinkage of endometrial neoplasias. In addition, palbociclib treatment significantly increased the survival of Pten-deficient mice, and, as expected, had a general effect in reducing tumour cell proliferation. To further analyse the effects of palbociclib on endometrial carcinoma, we established subcutaneous tumours with human endometrial cancer cell lines and primary endometrial cancer xenografts, which allowed us to provide more translational and predictive data. To date, this is the first preclinical study evaluating the response to CDK4/6 inhibition in endometrial malignancies driven by PTEN deficiency, and it reveals an important role of cyclin D-CDK4/6 activity in their development.

    Large serrated polyps (SP), proximal SP, SP with dysplasia and the presence of multiple sessile serrated adenomas/polyps (SSA/P), which we refer to as SP with increased risk of metachronous lesions (SPIRML), have been associated with an increased risk of advanced colon lesions on follow-up. It is unclear, however, whether SPIRML are also associated with an increased risk of synchronous advanced colorectal neoplasia (ACN). The aim of this study was to estimate the prevalence of SPIRML and to evaluate the association between SPIRML and synchronous ACN. A cross-sectional population-based study in all patients (1,538) with histological diagnosis of SP obtained from colonoscopies, sigmoidoscopies and colonic surgery performed in Navarra Health Service hospitals (Spain) in 2011. Demographic parameters and synchronous colonic lesions (adenomas, advanced adenomas [AA] and ACN) were analyzed. One fourth of the sample (384 patients) presented SPIRML. These were older patients, with a slight predominance of women, and with no differences in body mass index (BMI) compared to patients without SPIRML. In the univariate analysis, patients with SPIRML showed an increased risk of adenoma, AA and ACN. In the multivariate analysis, the SPIRML group had a higher risk of synchronous AA and ACN (odds ratio [OR]: 2.38 [1.77-3.21] and OR: 2.29 [1.72-3.05], respectively); in the case of ACN, this risk was statistically significant in both locations (proximal or distal), with OR slightly higher for the proximal location. Different subtypes of SPIRML had a higher risk of AA and synchronous NA. SPIRML were common in patients with SP, and their presence was associated with an increased risk of synchronous ACN.

    There are 2 types of vulvar intraepithelial neoplasia (VIN): warty-basaloid and differentiated. Differentiated VIN is uncommon and seldom diagnosed prior to carcinoma and, traditionally, is not graded. There are currently 3 grading systems for warty-basaloid VIN: the World Health Organization (WHO) 3 grade system of VIN 1-3, a 2 grade system of low and high grade vulvar intraepithelial lesions, and the revised International Society for the Study of Vulvovaginal Disease (ISSVD) classification which has no grading of VIN. According to the ISSVD, VIN 1 should be abolished and VIN 2 and 3 combined into a single category, simply termed warty-basaloid VIN. To determine the best system for grading warty-basaloid VIN and learn more about differentiated VIN, we reviewed the pathology of 164 consecutive women with VIN. Of these, 134 (82.3%) had warty-basaloid VIN, 29 (18.2%) had differentiated VIN, and 1 had both. Of warty-basaloid VIN cases, 4 had VIN 1, 13 VIN 2, and 118 VIN 3 when graded according to the WHO. All VIN 1 occurred in condylomata acuminata. VIN 2 and 3 were distinguished only by degree of abnormality. Differentiated VIN was diagnosed before SCC in only 7 cases (26.7%). Because the only VIN 1 cases seen were in condylomata acuminata and because VIN 2 and 3 were difficult to distinguish and there appears little clinical reason to do so, our study supports the ISSVD proposal that VIN 1 be abolished and VIN 2 and 3 be combined. There needs to be more clinical awareness of vulvar conditions, so that differentiated VIN is biopsied before cancer has supervened.

    Papillomaviruses have evolved over many millions of years to propagate themselves at specific epithelial niches in a range of different host species. This has led to the great diversity of papillomaviruses that now exist, and to the appearance of distinct strategies for epithelial persistence. Many papillomaviruses minimise the risk of immune clearance by causing chronic asymptomatic infections, accompanied by long-term virion-production with only limited viral gene expression. Such lesions are typical of those caused by Beta HPV types in the general population, with viral activity being suppressed by host immunity. A second strategy requires the evolution of sophisticated immune evasion mechanisms, and allows some HPV types to cause prominent and persistent papillomas, even in immune competent individuals. Some Alphapapillomavirus types have evolved this strategy, including those that cause genital warts in young adults or common warts in children. These strategies reflect broad differences in virus protein function as well as differences in patterns of viral gene expression, with genotype-specific associations underlying the recent introduction of DNA testing, and also the introduction of vaccines to protect against cervical cancer. Interestingly, it appears that cellular environment and the site of infection affect viral pathogenicity by modulating viral gene expression. With the high-risk HPV gene products, changes in E6 and E7 expression are thought to account for the development of neoplasias at the endocervix, the anal and cervical transformation zones, and the tonsilar crypts and other oropharyngeal sites. A detailed analysis of site-specific patterns of gene expression and gene function is now prompted.

    Full text: An 123 I meta-iodobenzylguanidine (MIBG) scan was performed on a 54-year-old lady with familial phaeochromocytoma, to evaluate for bilateral or extra-adrenal disease. She has hypertension with raised catecholamines and CT evidence of a right adrenal phaeochromocytoma, and a female sibling with bilateral phaeochromocytoma. Thyroid blockade using Lugol's Iodine was given orally prior to intravenous administration of 370 MBq 123 I MIBG. Planar and SPECT imaging were acquired at 24 hours. There was intense uptake in the known right phaeochromocytoma. An unexpected finding was focal intense uptake in the region of the right thyroid lobe, which may be either a functioning paraganglioma arising from the cervical sympathetic ganglia or a medullary thyroid carcinoma (MTC). At 48 hours, a further image of the neck showed no changes. This was followed by a standard injection of 150 MBq 99 Tc m pertechnetate for thyroid scanning. Imaging obtained on 99 Tc m energy window setting showed a large hypofunctioning region in the right thyroid lobe, corresponding in location to the focal 123 I MIBG uptake. This is in keeping with a MTC, a neuroendocrine tumour, as other thyroid carcinomas are non-MIBG avid. A subsequent serum calcitonin assay showed elevated levels. The patient underwent surgical removal of the right phaeochromocytoma followed several weeks later by a right hemithyroidectomy. Histological reports confirmed the tumour diagnoses. The patient's familial phaeochromocytoma is therefore part of the multiple endocrine neoplasia syndrome Type 2A (MEN 2A). To date, biochemistry has not shown any evidence of hyperparathyroidism which occurs in 15-20 per cent of patients with MEN 2A.

    vulvar intraepithelial neoplasia is a non-invasive precursor lesion found in 50-70% of patients affected by vulvar squamous cell carcinoma. In the past, radical surgery was the standard treatment for vulvar intraepithelial neoplasia, however, considering the psychological and physical morbidities related to extensive surgery, several less aggressive treatment modalities have been proposed since the late 1970s. Photodynamic therapy is an effective and safe treatment for cutaneous non-melanoma skin cancer, with favorable cosmetic outcomes. in the present paper, the results of selected studies on photodynamic therapy in the treatment of vulvar intraepithelial neoplasia are reported and discussed. Overall, complete histological response rates ranged between 20% and 67% and symptom response rates ranged between 52% and 89% according to different studies and case series. the real benefit of photodynamic therapy in the setting of vulvar intraepithelial neoplasia lies in its ability to treat multi-focal disease with minimal tissue destruction, preservation of vulvar anatomy and excellent cosmetic outcomes. These properties explain why photodynamic therapy is an attractive option for vulvar intraepithelial neoplasia treatment.

    Synchronous gastric neoplasms are not infrequently detected, thus endoscopic submucosal dissection (ESD) for multiple early gastric neoplasia is occasionally considered. However, there have been few investigations of the safety and feasibility of simultaneous ESD for multiple gastric lesions. This study aims to evaluate the safety and feasibility of simultaneous ESD for multiple gastric neoplasia. A total of 1823 patients who underwent ESD for 1929 gastric adenomas or early gastric cancers were retrospectively reviewed in this study. Two hundred gastric adenomas or early gastric cancers among 94 patients were treated by ESD simultaneously (multiple group), and 1729 patients were treated with ESD for a single lesion (single group). En bloc resection (P = 0.060), complete resection (P = 0.362) and curative resection (P = 0.108) rates did not differ between the two groups. Rates of adverse events including bleeding (P = 0.317), perforation (P = 0.316) and aspiration pneumonia (P = 0.563) were not higher in the multiple group. Long-term follow-up showed more frequent local recurrence (P neoplasia (P = 0.041) and metachronous neoplasia (P neoplasia is required.

    Multiple endocrine neoplasia (MEN) is a well-known syndrome in human medicine, whereas only a few cases of concurrent endocrine neoplasias have been reported in dogs and cats. The aim of this study was to evaluate the prevalence of concurrent endocrine neoplasias in dogs and cats at our clinic, identify possible breed and sex predispositions and investigate similarities with MEN syndromes in humans. Postmortem reports of 951 dogs and 1155 cats that died or were euthanased at the Clinic for Small Animal Internal Medicine, University of Zurich, between 2004 and 2014 were reviewed, and animals with at least two concurrent endocrine neoplasias and/or hyperplasias were included. Twenty dogs and 15 cats met the inclusion criteria. In dogs, the adrenal glands were most commonly affected. Multiple tumours affecting the adrenal glands and the association of these tumours with pituitary adenomas were the most common tumour combinations. Only one dog had a combination resembling human MEN type 1 syndrome (pituitary adenoma and insulinoma). In cats, the thyroid glands were most commonly affected and there were no similarities to human MEN syndromes. The prevalence of concurrent endocrine neoplasia was 2.1 per cent in dogs and 1.3 per cent in cats and MEN-like syndromes are very rare in these species. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

    Flat epithelial lesions of the biliary tract cannot be detected by the image analysis, and the diagnosis entirely depends on pathological examination. The biliary tract is often affected by inflammatory conditions, and the resultant changes of the biliary epithelium make it difficult to differentiate them from neoplasia. Thus, the pathological diagnosis of biliary flat epithelial lesions can be challenging. In the biliary tract, there are several forms of intraepithelial neoplasia of the flat type, and biliary intraepithelial neoplasia (BilIN) is known as one of such lesions that represent the multistep cholangiocarcinogenesis. In this article, the diagnostic criteria and the differential diagnosis of biliary flat epithelial lesions, particularly focusing on BilIN, were presented and discussed to provide help to advance clinical and research applications of the BilIN system.

    To estimate the clinical significance of serum anti-human papillomavirus (HPV) antibodies and high-risk cervical HPV DNA in cervical neoplasia. The study population comprised patients who were histopathologically diagnosed with cervical intraepithelial neoplasia (CIN) 1 (n=64), CIN 2 and 3 (n=241), cervical cancer (n=170), and normal control participants (n=975). Cervical HPV DNA tests were performed through nucleic acid hybridization assay tests, and serum anti-HPV 16 and 18 antibodies were measured by competitive immunoassay. The associations of HPV DNA and anti-HPV antibodies were evaluated with demographic characteristics and compared according to the levels of disease severity. Anti-HPV antibodies were also investigated with clinicopathologic parameters, including survival data. Among various demographic characteristics, factors involving sexual behavior had a higher tendency of HPV DNA positivity and HPV seropositivity. Human papillomavirus DNA mean titer and positivity were both increased in patients with cervical neoplasia compared with those with normal control participants, but there was no statistical difference among types of cervical neoplasia. Serum anti-HPV 16 antibodies were also able to differentiate cervical neoplasia from a normal control participant and furthermore distinguished CIN 1 from CIN 2 and 3 (odd ratio 2.87 [1.43-5.78], P=.002). In cervical cancer, HPV 16 seropositivity was associated with prolonged disease-free survival according to the univariable analysis (hazard ratio=0.12 [0.01-0.94], P=.044). Serum anti-HPV 16 antibodies can distinguish cervical neoplasia from a normal control and has the advantage of identifying high-grade CIN. Moreover, in cervical cancer, HPV 16 seropositivity may be associated with a more favorable prognosis. II.

    The extent of association of human papilloma virus (HPV) in human conjunctival neoplasias has been debated in studies originating from different parts of the world, but no substantial evidence has been generated on Indian subjects. This prompted us to carry out a retrospective study on conjunctival neoplasias diagnosed over the past 12 years. Histopathological and immunohistochemical analysis of 65 specimens of ocular neoplasias and 30 normal controls diagnosed between 1991 and 2002 at a tertiary eye care hospital, was undertaken. Formalin-fixed, paraffin-embedded tissues were reviewed for confirming histopathological diagnosis, presence of koilocytosis and changes related to actinic keratosis. Immunohistochemical analysis was done using HPV-specific monoclonal antibodies. Clinicopathological correlation and the association of HPV antigen with the histopathological features were performed. Out of the 65 cases analyzed, 35 were papillomas and 30 were ocular surface squamous neoplasias (OSSN). The mean age was 48 years with a male preponderance. Histologically, koilocytosis was observed in 17.1% of papillomas and 36.6% of OSSN. Actinic keratosis was present in 33% of OSSN. Immunohistochemically 17.1% conjunctival papillomas stained positive for HPV antigen, all cases of OSSN were negative for HPV. There was no correlation between koilocytosis or actinic keratosis and the detection of HPV antigen. The association between HPV and conjunctival neoplasias is variable in different geographical areas and also depends on the methods of detection used. This study warrants the need for applying more advanced techniques at a molecular level to determine the possible etiology of HPV in conjunctival neoplasias among Asian-Indians.

    Hyperplasia of the parathyroid glands is a central feature of familial multiple endocrine neoplasia type 1. We used cultured bovine parathyroid cells to test for mitogenic activity in plasma from patients with this disorder. Normal plasma stimulated [ 3 H]thymidine incorporation, on the average, to the same extent as it was stimulated in a plasma-free control culture. This contrasted with the results of the tests with plasma from patients with familial multiple endocrine neoplasia type 1, in which parathyroid mitogenic activity increased 2400 percent over the control value (P less than 0.001). Plasma from these patients also stimulated the proliferation of bovine parathyroid cells in culture, whereas plasma from normal subjects inhibited it. Parathyroid mitogenic activity in plasma from the patients with familial multiple endocrine neoplasia type 1 was greater than that in plasma from patients with various other disorders, including sporadic primary hyperparathyroidism (with adenoma, hyperplasia, or cancer of the parathyroid), sporadic primary hypergastrinemia, sporadic pituitary tumor, familial hypocalciuric hypercalcemia, and multiple endocrine neoplasia type 2 (P less than 0.05). Parathyroid mitogenic activity in the plasma of patients with familial multiple endocrine neoplasia type 1 persisted for up to four years after total parathyroidectomy. The plasma also had far more mitogenic activity in cultures of parathyroid cells than did optimal concentrations of known growth factors or of any parathyroid secretagogue. This mitogenic activity had an apparent molecular weight of 50,000 to 55,000. We conclude that primary hyperparathyroidism in familial multiple endocrine neoplasia type 1 may have a humoral cause

    Volumetric laser endomicroscopy (VLE) is an advanced imaging system that provides a near-microscopic resolution scan of the esophageal wall layers up to 3-mm deep. VLE has the potential to improve detection of early neoplasia in Barrett's esophagus (BE). However, interpretation of VLE images is complex because of the large amount of data that need to be interpreted in real time. The aim of this study was to investigate the feasibility of a computer algorithm to identify early BE neoplasia on ex vivo VLE images. We used 60 VLE images from a database of high-quality ex vivo VLE-histology correlations, obtained from BE patients ± neoplasia (30 nondysplastic BE [NDBE] and 30 high-grade dysplasia/early adenocarcinoma images). VLE features from a recently developed clinical VLE prediction score for BE neoplasia served as input for the algorithm: (1) higher VLE surface than subsurface signal and (2) lack of layering. With this input, novel clinically inspired algorithm features were developed, based on signal intensity statistics and grayscale correlations. For comparison, generic image analysis methods were examined for their performance to detect neoplasia. For classification of the images in the NDBE or neoplastic group, several machine learning methods were evaluated. Leave-1-out cross-validation was used for algorithm validation. Three novel clinically inspired algorithm features were developed. The feature "layering and signal decay statistics" showed the optimal performance compared with the other clinically features ("layering" and "signal intensity distribution") and generic image analyses methods, with an area under the receiver operating characteristic curve (AUC) of .95. Corresponding sensitivity and specificity were 90% and 93%, respectively. In addition, the algorithm showed a better performance than the clinical VLE prediction score (AUC .81). This is the first study in which a computer algorithm for BE neoplasia was developed based on VLE images with

    The ability of computed tomography and radiography to detect changes associated with nasal neoplasia was compared in dogs. Eighteen areas or anatomic structures were evaluated in 21 dogs for changes indicative of neoplasia. Computed tomography was superior (P < or = 0.05) to radiography for detecting changes in 14 of 18 areas. Radiography was not superior for detecting changes in any structure or area. Computed tomography reveals vital information not always detected radiographically to assist in providing a prognosis and in planning treatment for nasal neoplasms in dogs

    Full Text Available Condyloma acuminatum, intraepithelial neoplasia, and squamous cell carcinoma are three relatively frequent vulvar lesions. Condyloma acuminatum is induced by low risk genotypes of human papillomavirus (HPV. Vulvar intraepithelial neoplasia (VIN and squamous cell carcinoma have different etiopathogenic pathways and are related or not with high risk HPV types. The goal of this paper is to review the main pathological and clinical features of these lesions. A special attention has been paid also to epidemiological data, pathological classification, and clinical implications of these diseases.

    2003-01-01

    ONE OF THE RISK FACTORS FOR HUMAN PAPILLOMAVIRUS (HPV) INFECTION and subsequent lower genital tract neoplasias and cancers is impaired cell-mediated immunity. HIV-positive women with severe immunosuppression are 5 times more likely than HIV-negative women to have lower genital tract neoplasias. A corresponding increase in the risk of invasive vulvar and anal cancers, but not of cervical cancer, has also been observed among HIV-positive women. Treatment failure and recurrence of neoplasia occur much more frequently among HIV-positive than among HIV-negative women. In this review, we discuss recent advances in the understanding of the relation between HIV and HPV coinfection and the development of lower genital tract neoplasias and cancers in women. In addition, we present strategies for monitoring and treating noninvasive and invasive neoplasias of the lower genital tract in HIV-positive women. PMID:12952805

    Full Text Available Abstract Background Heat shock protein 90 (Hsp90 overexpression has been implicated in breast carcinogenesis, with putative prognostic and therapeutic implications. The purpose of this study is to evaluate the immunohistochemical expression of Hsp90 and to examine whether Hsp90 expression is associated with estrogen receptor alpha (ER-alpha and beta (ER-beta immunostaining in lobular neoplasia (LN of the breast. Methods Tissue specimens were taken from 44 patients with LN. Immunohistochemical assessment of Hsp90, ER-alpha and ER-beta was performed both in the lesion and the adjacent normal breast ducts and lobules; the latter serving as control. As far as Hsp90 evaluation is concerned: i the percentage of positive cells, and ii the intensity was separately analyzed. Additionally, the Allred score was adopted and calculated. Accordingly, Allred score was separately evaluated for ER-alpha and ER-beta. The intensity was treated as an ordinal variable-score (0: negative, low: 1, moderate: 2, high: 3. Statistical analysis followed. Results Hsp90 immunoreactivity was mainly cytoplasmic in both the epithelial cells of normal breast (ducts and lobules and LN. Some epithelial cells of LN also showed nuclear staining, but all the LN foci mainly disclosed a positive cytoplasmic immunoreaction for Hsp90. In addition, rare intralobular inflammatory cells showed a slight immunoreaction. The percentage of Hsp90 positive cells in the LN areas was equal to 67.1 ± 12.2%, whereas the respective percentage in the normal adjacent breast tissue was 69.1 ± 11.6%; the difference was not statistically significant. The intensity score of Hsp90 staining was 1.82 ± 0.72 in LN foci, while in the normal adjacent tissue the intensity score was 2.14 ± 0.64. This difference was statistically significant (p = 0.029, Wilcoxon matched-pairs signed-ranks test. The Hsp90 Allred score was 6.46 ± 1.14 in the LN foci, significantly lower than in the normal adjacent tissue (6.91

    2017-04-01

    Full Text Available A pesar de que la alfabetización digital en medios se reconoce como una de las competencias esenciales necesarias para vivir en una nueva era de los medios de comunicación, solo acaba de empezar a ganar atención en la educación primaria de Taiwán. Una de las razones es la educación orientada a los exámenes, y como consecuencia, el que se desvíe muy pocos recursos para este aprendizaje informal. La otra razón es que los educadores tienden a pensar en la educación en medios digitales como una serie de operaciones puramente técnicas, lo que podría llevar a los estudiantes de medios digitales a aprender a trabajar sin sentido. Por lo tanto, este estudio diseñó una exhibición de contenidos basada en el modelo de aprendizaje experiencial de Kolb con el fin de enseñar a los estudiantes conceptos de videos stop-motion y técnicas de producción cinematográfica. El experimento diseñado involucró a 247 estudiantes de tercer grado de primaria que fueron agrupados para visitar la exposición experiencial. Los hallazgos sugieren una mejora en los estudiantes de su conocimiento de videos stop-motion. El análisis de los vídeos producidos también muestra que han mejorado su capacidad mediática para representar sus ideas y comunicarse con los demás. A través del análisis de la influencia de la demografía en la prueba de conocimiento, los hallazgos revelan que la exposición experiencial es más efectiva para los estudiantes de primaria femeninos, y que las experiencias anteriores relevantes de los estudiantes no deberían afectar a los conocimientos adquiridos. Teniendo en cuenta estos resultados y observaciones, creemos que la exposición experimental propuesta es una forma prometedora de llevar a cabo la educación en alfabetización digital en las escuelas primarias.

    Full Text Available CONTEXT: The treatment of the subclinical Human papillomavirus (HPV infection of the uterine cervix is controversial. OBJECTIVE: To assess the efficacy of any therapy for subclinical HPV infection of the cervix without intraepithelial neoplasia, via a search in the medical literature. METHOD: We performed a systematic review with a comprehensive reference search in Medline, LILACS, Excerpta Medica, AIDSLINE, Popline, Cochrane Library and other authors' reference lists to identify experimental studies of therapy for subclinical HPV infection without intraepithelial neoplasia of the uterine cervix. In order to identify unpublished studies, we also contacted experts in the area, clinical trial registries, pharmaceutical industries, government and research institutions. We also searched on the Internet and in the book-of-abstracts of some medical conferences. The studies identified were masked and selected by inclusion criteria to help ascertain their internal validity. The data about regression or progression of HPV infection were extracted from the studies included. RESULTS: We identified 67 studies related to the treatment of subclinical HPV infection without intraepithelial neoplasia of the uterine cervix. Only five clinical trials matched the inclusion criteria and none demonstrated significant differences between the experimental group and the control group concerning regression of HPV infection (with or without CIN I or progression to higher grades of CIN. CONCLUSION: The evidence we found in the medical literature regarding the efficacy of any therapy for subclinical HPV infection without intraepithelial neoplasia of the uterine cervix was unsatisfactory.

    To evaluate the distribution of GTPases RhoA, RhoB, and Cdc42 in cervical intraepithelial neoplasias (CIN) and invasive neoplasias of the uterine cervix. samples of neoplastic lesions of the uterine cervix of 44 patients were classified in: CIN I (n = 10), CIN II (n = 10), CIN III (n = 09), and invasive carcinoma (n = 15). Antibodies anti-RhoA, anti-RhoB, and anti-Cdc42 were used and staining was classified as: negative, mild, moderate, and intense positive. When compared with dysplastic cells, superficial cells showed: higher expression of RhoB in CIN I (p = 0.0018), and lower expression of Cdc42 in CIN I (p = 0.0225). The authors observed higher expression of RhoA (p = 0.0002) and RhoB (p = 0.0046) in CIN dysplastic cells when compared with invasive carcinoma cells. GTPases Rho may be involved with the regulation of biological processes, important to the progression of cervical neoplasias. Probably, RhoA is important for maintenance of cell differentiation and RhoB protects cells from malignant cervical neoplasia.

    The aim of this study was to investigate the relationship between microsatellite instability (MSI) and clinicopathologic features including multiplicity in early stage gastric neoplasias (ESGN). From November 2004 until September 2009, 372 patients with consecutive resected gastric neoplasias were retrospectively enrolled. The gastric neoplasias were composed of 117 advanced gastric cancers (AGCs) and 255 ESGNs including 31 gastric dysplasias (including low and high grade dysplasia) and 224 early gastric cancers (EGCs). Based on microsatellite markers, high MSI (MSI-H) was observed in 61 cases (16.4%) and low MSI (MSI-L) in 14 cases (3.8%) of 372 cases. There was a positive correlation between the presence of MSI-H and progression of gastric adenoma to gastric tumor. We compared ESGNs with microsatellite stable (MSS; 223 cases, 87.5%) and ESGNs with MSI-H (24 cases, 9.4%). The ESGNs with MSI-H were only associated with older age and female gender. There were no association with Helicobacter pylori infection, intestinal metaplasia, and distal location in contrast with EGCs with MSI-H. Furthermore, multiplicity of ESGNs was not associated with MSI status. The clinicopatholgic features of MSI-H phenotype were different according to the progression of gastric neoplasias from ESGNs to AGCs. ESGNs with MSI-H were only associated with old age, female sex. In addition ESGNs with MSI-H were not associated with an increased risk of multifocal tumors. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    AIM: To evaluate the effectiveness of trimodal imaging endoscopy (TME) to detect another lesion after endoscopic submucosal dissection (ESD) for superficial gastric neoplasia (SGN). METHODS: Surveillance esophagogastroduodenoscopy (EGD) using a TME was conducted in 182 patients that had undergone ESD for SGN. Autofluorescence imaging (AFI) was conducted after white-light imaging (WLI). When SGN was suspicious, magnifying endoscopy with narrow-band imaging (ME-NBI) was conducted. Final diagnoses were made by histopathologic findings of biopsy specimens. The detection rates of lesions in WLI, AFI, and NBI, and the characteristics of lesions detected by WLI and ones missed by WLI but detected by AFI were examined. The sensitivity, specificity, and accuracy of endoscopic diagnosis using WLI, AFI and ME-NBI were evaluated. RESULTS: In 242 surveillance EGDs, 27 lesions were determined pathologically to be neoplasias. Sixteen early gastric cancers and 6 gastric adenomas could be detected by WLI. Sixteen lesions were reddish and 6 were whitish. Five gastric neoplasias were missed by WLI but were detected by AFI, and all were whitish and protruded gastric adenomas. There was a significant difference in color and pathology between the two groups (P = 0.006). Sensitivity, specificity and accuracy in ME-NBI were higher than those in both WLI and AFI. Specificity and accuracy in AFI were lower than those in WLI. CONCLUSION: Surveillance using trimodal imaging endoscopy might be useful for detecting another lesion after endoscopic submucosal dissection for superficial gastric neoplasia. PMID:25473189

    Full Text Available The bone mineral density increments in patients with sporadic primary hyperparathyroidism after parathyroidectomy have been studied by several investigators, but few have investigated this topic in primary hyperparathyroidism associated with multiple endocrine neoplasia type 1. Further, as far as we know, only two studies have consistently evaluated bone mineral density values after parathyroidectomy in cases of primary hyperparathyroidism associated with multiple endocrine neoplasia type 1. Here we revised the impact of parathyroidectomy (particularly total parathyroidectomy followed by autologous parathyroid implant into the forearm on bone mineral density values in patients with primary hyperparathyroidism associated with multiple endocrine neoplasia type 1. Significant increases in bone mineral density in the lumbar spine and femoral neck values were found, although no short-term (15 months improvement in bone mineral density at the proximal third of the distal radius was observed. Additionally, short-term and medium-term calcium and parathyroid hormone values after parathyroidectomy in patients with primary hyperparathyroidism associated with multiple endocrine neoplasia type 1 are discussed. In most cases, this surgical approach was able to restore normal calcium/parathyroid hormone levels and ultimately lead to discontinuation of calcium and calcitriol supplementation.

    Full Text Available Usually, primary hyperparathyroidism is the first endocrinopathy to be diagnosed in patients with multiple endocrine neoplasia type 1, and is also the most common one. The timing of the surgery and strategy in multiple endocrine neoplasia type 1/hyperparathyroidism are still under debate. The aims of surgery are to: 1 correct hypercalcemia, thus preventing persistent or recurrent hyperparathyroidism; 2 avoid persistent hypoparathyroidism; and 3 facilitate the surgical treatment of possible recurrences. Currently, two types of surgical approach are indicated: 1 subtotal parathyroidectomy with removal of at least 3-3 K glands; and 2 total parathyroidectomy with grafting of autologous parathyroid tissue. Transcervical thymectomy must be performed with both of these procedures. Unsuccessful surgical treatment of hyperparathyroidism is more frequently observed in multiple endocrine neoplasia type 1 than in sporadic hyperparathyroidism. The recurrence rate is strongly influenced by: 1 the lack of a pre-operative multiple endocrine neoplasia type 1 diagnosis; 2 the surgeon's experience; 3 the timing of surgery; 4 the possibility of performing intra-operative confirmation (histologic examination, rapid parathyroid hormone assay of the curative potential of the surgical procedure; and, 5 the surgical strategy. Persistent hyperparathyroidism seems to be more frequent after subtotal parathyroidectomy than after total parathyroidectomy with autologous graft of parathyroid tissue. Conversely, recurrent hyperparathyroidism has a similar frequency in the two surgical strategies. To plan further operations, it is very helpful to know all the available data about previous surgery and to undertake accurate identification of the site of recurrence.

    To quantify how long the different steps in the process of editing the manuscripts received by the journal Atención Primaria took. Retrospective, descriptive study. The journal Atención Primaria. Manuscripts submitted for publication in the sections Original articles, Short articles and Letters to the Editor between January 1 and June 30 1997 (6 months). Retrospectively, information was collected on the dates of receipt, of sending out to referees, receipt of their views and comments, sending back to the authors, receipt of their modified text or reply, of final decision on acceptance or rejection, and of publication if accepted. Of the 132 original and short articles received, 22 (16.7%) were awaiting a final decision. Of the remaining 110, 53 (48.2%) had been rejected and 57 (51.8%) accepted. The length of each step in the editorial process was less than 30 days for half the manuscripts. The time elapsed from receipt to editorial decision was less than 45 days in half the cases and 60 days on average. The time from acceptance to publication was 137 days on average. How long each step in the editorial process took can be considered acceptable, although the wide variability in the times taken by authors to modify their manuscripts is striking. Mechanisms must be sought to avoid the excessive delay in the publication of research, by increasing the speed of the referees' reviews and of authors' modifications.

    The Ni classification of vascular change from 2011 is well documented for evaluating pharyngeal and laryngeal lesions, primarily focusing on cancer. In the planning of surgery it may be more relevant to differentiate neoplasia from non-neoplasia. We aimed to evaluate the ability of the Ni classification to predict laryngeal or hypopharyngeal neoplasia and to investigate if a changed cutoff value would support the recent European Laryngological Society (ELS) proposal of perpendicular vascular changes as indicative of neoplasia. PubMed, Embase, Cochrane, and Scopus databases. A systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. We systematically searched for publications from 2011 until 2016. All retrieved studies were reviewed and qualitatively assessed. The pooled sensitivity and specificity of the Ni classification with two different cutoffs were calculated, and bubble and summary receiver operating characteristics plots were created. The combined sensitivity of five studies (n = 687) with Ni type IV-V defined as test-positive was 0.89 (95% confidence interval [CI]: 0.76-0.95), and specificity was 0.82 (95% CI: 0.72-0.89). The equivalent combined sensitivity of four studies (n = 624) with Ni type V defined as test-positive was 0.82 (95% CI: 0.75-0.87), and specificity was 0.93 (95% CI: 0.82-0.97). The diagnostic accuracy of the Ni classification in predicting neoplasia was high, without significant difference between the two analyzed cutoff values. Implementation of the proposed ELS classification of vascular changes seems reasonable from a clinical perspective, with comparable accuracy. Attention must be drawn to the accompanying risk of exposing patients to unnecessary surgery.

    The incidence of and mortality from colorectal cancers (CRC) can be reduced by early detection. Currently there is a lack of established markers to detect early neoplastic changes. We aimed to identify the copy number variations (CNVs) and the associated genes which could be potential markers for the detection of neoplasia in both ulcerative colitis-associated neoplasia (UC-CRN) and sporadic colorectal neoplasia (S-CRN). We employed array comparative genome hybridization (aCGH) to identify CNVs in tissue samples of UC nonprogressor, progressor and sporadic CRC. Select genes within these CNV regions as a panel of markers were validated using quantitative real time PCR (qRT-PCR) method along with the microsatellite instability (MSI) in an independent cohort of samples. Immunohistochemistry (IHC) analysis was also performed. Integrated analysis showed 10 overlapping CNV regions between UC-Progressor and S-CRN, with the 8q and 12p regions showing greater overlap. The qRT-PCR based panel of MYC, MYCN, CCND1, CCND2, EGFR and FNDC3A was successful in detecting neoplasia with an overall accuracy of 54 % in S-CRN compared to that of 29 % in UC neoplastic samples. IHC study showed that p53 and CCND1 were significantly overexpressed with an increasing frequency from pre-neoplastic to neoplastic stages. EGFR and AMACR were expressed only in the neoplastic conditions. CNVs that are common and unique to both UC-associated and sporadic colorectal neoplasm could be the key players driving carcinogenesis. Comparative analysis of CNVs provides testable driver aberrations but needs further evaluation in larger cohorts of samples. These markers may help in developing more effective neoplasia-detection strategies during screening and surveillance programs.

    Since Warburg proposed that cancer cells exhibit increased glycolysis due to apparent mitochondrial damage, numerous researchers have assumed that glycolysis is the predominant ATP supplier for cancer cell energy-dependent processes. However, chemotherapeutic strategies using glycolytic inhibitors have been unsuccessful in arresting tumor proliferation indicating that the original Warburg proposal may not be applicable to all existing neoplasias. This review analyzes recent information on mitochondrial metabolism in several malignant neoplasias emphasizing that, although tumor cells maintain a high glycolytic rate, the principal ATP production may derive from active oxidative phosphorylation. Thus, anti-mitochondrial drug therapy may be an adequate strategy to arrest proliferation of oxidative phosphorylation-dependent neoplasias.

    Full Text Available Una delle principali difficoltà che incontrano i bambini della scuola primaria nella produzione scritta riguarda la coesione verbale, ovvero il mantenimento lungo il testo della dimensione temporale inizialmente selezionata per riportare gli eventi. L’articolo esamina questo specifico tipo di competenza testuale negli alunni di sei classi del secondo ciclo della scuola primaria, tre delle quali hanno partecipato alla sperimentazione educativa sulla produzione di testi scritti “Osservare l’interlingua”. Il confronto fra i dati raccolti all’inizio e alla fine dell’anno scolastico mostra una riduzione dei salti immotivati da un tempo verbale all’altro, definiti shift temporali, nei testi prodotti nelle classi del campione sperimentale in misura maggiore rispetto a quelle di controllo e sottolinea gli effetti positivi, a breve e lungo termine, di una didattica task-based condotta con approccio inclusivo, cooperativo ed attivo.  The process of writing: verb cohesion in primary school textsOne of principal difficulties in producing written texts for primary school pupils concerns verb cohesion, i.e. maintaining the temporal dimension initially chosen for expressing events throughout the text. The paper examines this specific textual competence in pupils from six classes within second cycle of primary school. Three of these classes were involved in the “Observing interlanguage” project focused on written production. The comparison of data collected at the beginning and the end of school year shows a decrease in temporal shifts (transitions from one verb tense to another in the texts produced by the students involved in the project with regard to the control group. These findings highlight the positive effects, both short-term and long-term, of task-based teaching through an inclusive, cooperative and active approach.

    Full Text Available Este estudio considera que el docente de ciencias debería ser mediador en la adquisición de habilidades de lectura y escritura en el área de Ciencias Naturales. Esto implica hacer transitar progresivamente a los estudiantes en los géneros específicos de las disciplinas, comenzando desde la escuela primaria. Este artículo propone el abordaje del género relato de procedimiento con el objeto de favorecer el aprendizaje de contenidos científicos mediante la escritura del procedimiento seguido en actividades experimentales llevadas a cabo en las clases de Ciencias Naturales. El estudio fue realizado en una escuela primaria de San Juan (Argentina con estudiantes de quinto grado en dos encuentros en los que se abordaron contenidos relacionados con el sonido y sus características. En el análisis de las producciones escritas por los alumnos consideramos la estructura del relato elaborado en cada instancia y el contenido científico explicitado en las producciones. Los resultados sugieren que el guion de estructura del género proporcionado a los estudiantes ha favorecido la comunicación escrita del relato acerca de los experimentos realizados. Esto se evidencia en aspectos relacionados con el orden de las ideas, su presentación en forma más completa y los intentos de explicación de los fenómenos en estudio, mejorando el uso del lenguaje de la ciencia y el aprendizaje disciplinar.

    Full Text Available La emergencia de las tecnologías de información y comunicación (TIC plantea nuevos desafíos educativos al profesorado, a los cuales puede responder desde un modelo de formación coherente. El propósito de este estudio es analizar los conocimientos tecnológicos, pedagógicos y disciplinares del profesorado de Educación Primaria, necesarios para la integración de las TIC en la labor docente. Para ello, se llevó a cabo una investigación con una metodología cuantitativa de carácter no experimental en la que participaron 224 profesores de Educación Infantil y Primaria de la provincia de Alicante. Los resultados mostraron que los docentes poseen mayores conocimientos pedagógicos y disciplinares que tecnológicos, lo que conlleva a escasos conocimientos para la integración de las TIC en la labor docente. Se constataron, además, diferencias significativas entre el género y los años de experiencia docente, y la relación entre el uso lúdico de la tecnología y los conocimientos sobre sus aspectos fundamentales. Según los resultados obtenidos, se corrobora la necesidad de una alfabetización digital del profesorado abordada no solo desde una formación tecnológica, sino también pedagógica y disciplinar de forma global. Ello responde al modelo TPACK (Technological, Pedagogical and Content Knowledge, el cual se contempla como un marco de referencia a tener en cuenta por lo que respecta al desarrollo profesional del profesorado y su vinculación a los procesos de enseñanza-aprendizaje en el aula donde las TIC estén presentes.

    The aim of this study was to integrate European epidemiological data on patients with multiple endocrine neoplasia type 1 by creating an Italian registry of this syndrome, including clinical and genetic characteristics and therapeutic management. Clinical, familial and genetic data of patients with multiple endocrine neoplasia type 1, diagnosed, treated, and followed-up for a mean time of 11.3 years, in 14 Italian referral endocrinological centers, were collected, over a 3-year course (2011-2013), to build a national electronic database. The Italian multiple endocrine neoplasia type 1 database includes 475 patients (271 women and 204 men), of whom 383 patients (80.6%) were classified as familial cases (from 136 different pedigrees), and 92 (19.4%) patients were sporadic cases. A MEN1 mutation was identified in 92.6% of familial cases and in 48.9% of sporadic cases. Four hundred thirty-six patients were symptomatic, presenting primary hyperparathyroidism, gastroenteropancreatic neuroendocrine tumors and pituitary tumors in 93, 53, and 41% of cases, respectively. Thirty-nine subjects, belonging to affected pedigrees positive for a MEN1 mutation, were asymptomatic at clinical and biochemical screening. Age at diagnosis of multiple endocrine neoplasia type 1 probands was similar for both familial and simplex cases (mean age 47.2 ± 15.3 years). In familial cases, diagnosis of multiple endocrine neoplasia type 1 in relatives of affected probands was made more than 10 years in advance (mean age at diagnosis 36.5 ± 17.6 years). The analysis of Italian registry of multiple endocrine neoplasia type 1 patients revealed that clinical features of Italian multiple endocrine neoplasia type 1 patients are similar to those of other western countries, and confirmed that the genetic test allowed multiple endocrine neoplasia type 1 diagnosis 10 years earlier than biochemical or clinical diagnosis.

    Multiple endocrine neoplasia type 2B (MEN2B) is a rare autosomal-dominant cancer syndrome characterized in part by metastatic medullary thyroid cancer (MTC) and pheochromocytoma. Cushing disease is a rare cause of endogenous hypercortisolism in children. We describe a 21-year-old African-American male who was diagnosed at age 10 with an ACTH-secreting pituitary microadenoma. At age 16 he developed medullary thyroid cancer and was found to have multiple endocrine neoplasia type 2B with the characteristic M918T mutation of the RET proto-oncogene. Following thyroidectomy, he was initiated on Vandetanib, a tyrosine kinase inhibitor, and has since had stable disease over the last 5 years. Our patient is the first individual with MEN2B to be described with Cushing disease. The RET oncogene may play a role in pituitary tumorigenesis; alternatively, the coexistence of these two entities may represent an extremely rare coincidence.

    1994-08-01

    The occurrence of mutations in the RET protooncogene has been investigated in 12 multiple endocrine neoplasia type 2A families and 18 cases of sporadic thyroid medullary carcinomas and pheochromocytomas. Ten of 12 families showed single base substitutions in the RET protooncogene exons 10 and 11, coding for the extracellular domain of the protein. Tumor tissues from 2 multiple endocrine neoplasia type 2A patients were analyzed at the DNA and ribonucleic acid levels and revealed the same heterozygous mutations found in the peripheral blood lymphocytes. This demonstrates that both the normal and mutant alleles are expressed. No mutations in these exons were detected in the 18 cases of sporadic tumors investigated. These data provide further evidence that the mutated RET protooncogene acts in a dominant fashion and is responsible for the pathogenesis of this syndrome. 28 refs., 2 figs., 1 tab.

    Although sensitive human chorionic gonadotropin assays and advances in chemotherapy have assumed primary importance in the management of gestational trophoblastic neoplasia, surgery remains important in the overall care of these patients. Management of molar pregnancies consists of surgical evacuation and subsequent monitoring. Hysterectomy decreases the risk of post-molar trophoblastic disease in appropriate patients and, when incorporated to primary management of gestational trophoblastic neoplasia, can decrease the chemotherapy requirements of patients with low-risk disease. In patients with high-risk disease, surgical intervention is frequently required to control complications of disease or as therapy to stabilize patients during chemotherapy. Hysterectomy, thoracotomy, or other extirpative procedures may be integrated into the management of patients with chemorefractory disease. Interventional procedures are useful adjuncts to control bleeding from metastases.

    Extra-adrenal myelolipomas are rare, benign tumors composed of adipose tissue and hematopoietic cells. Almost all myelolipomas occur within the adrenal gland. Only 50 cases of myelolipomas were described in literature and none of these were associated with gastric mesenchymal neoplasia. A 72-year-old male patient presented to a family medicine outpatient clinic with dyspnea and urinary urgency. His abdominal sonography revealed a 9-cm intra-abdominal mass. An incidental finding was 2 separate masses 1 cm each on the serosal surface of the stomach. The pathology specimen of the retroperitoneal mass revealed myelolipoma histopathology while gastric masses were reported as spindle cell mesenchymal neoplasias. The association of gastric spindle cell tumor and myelolipoma was not reported before in medical literature. Extra-adrenal myelolipomas are rare lesions, but should be considered in the differential diagnosis of fat containing retroperitoneal masses that are well circumscribed.

    This is an update of a Cochrane review that was first published in Issue 1, 2009. Gestational trophoblastic neoplasia (GTN) is a rare but curable disease arising in the fetal chorion during pregnancy. Most women with low-risk GTN will be cured by evacuation of the uterus with or without single-agent chemotherapy. However, chemotherapy regimens vary between treatment centres worldwide and the comparable benefits and risks of these different regimens are unclear.

    Full Text Available Background: Cervical cancer is one of the commonest malignancies and a leading cause of morbidity and mortality among women. The aim of this study was to evaluate the diagnostic value of Papanicolaou (PAP smear and visual inspection with acetic acid as methods of cervical cancer screening.Materials and Methods: This was a observational cross-sectional study conducted from the period of 2068.11.01 to 2069.11.01. The study population consisted of women with histologically confirmed cervical intraepithelial neoplasia or invasive carcinoma who had undergone prior PAP smear.Results: During the study period 160 patients underwent both PAP smear and cervical biopsy. Of these patients, 49 had a histological diagnosis of cervical intraepithelial neoplasia or invasive carcinoma. The histopathological and cytological diagnoses were compared. Visual inspection with acetic acid status was available for 31 of the 49 cases. The sensitivity of PAP smear was 61%, specificity 97%, positive predictive value 91%, negative predictive value 85% and diagnostic accuracy 86% for detection of cervical neoplasia. Visual inspection with acetic acid had a sensitivity of 74%, specificity 48%, Positive predictive value 64%, Negative predictive value 60% and diagnostic accuracy of 63%. Combining the two procedures increased sensitivity by 26%, Negative predictive value by 11%  and diagnostic accuracy by 2 per cent.Conclusion: PAP smear has a higher specificity, Positive predictive value, Negative predictive value and diagnostic accuracy but lower sensitivity than visual inspection with acetic acid. Visual inspection with acetic acid by itself is not an effective screening method. A combination of PAP smear and visual inspection with acetic acidcan ensure adequate screening of cervical neoplasia.

    An important percentage of vulvar and vaginal cancers may be attributed to infections by the human papillomavirus. Although the incidence of invasive vulvar and vaginal cancers is low, it has remained stable over the past years. Hospital discharges related to malignant neoplasias and in situ carcinomas of the vulva and vagina from 1997 to 2008 were selected from the Minimum Data Set of the Ministry of Health in Spain. 17,883 hospital admissions related to vulvar and vaginal malignant neoplasias and 2,185 admissions related to in situ carcinomas of the vulva and vagina were gathered, with a hospitalization rate of 7,054 and 0.862 discharges per 100,000 women/year, respectively. The mean age of patients was 57 (SD:18) years, and the mean length of hospital stay was 8 (SD:10) days. There was a statistically significant increase in the hospitalization rate for malignant neoplasias and in situ carcinomas with increasing patient age. This increase was significant for all locations. Overall, there was a case fatality rate of 9.34% for vulvar and vaginal malignant neoplasias and 0.46% for in situ carcinomas of an external genital organ. Mortality and case fatality rates increased significantly throughout the length of the study. 92% of all deaths occurred in those older than 55 years of age. Mortality and case fatality rates also increased significantly with age. The hospitalization rate follows a north-south pattern. These data of the pre-anti-HPV vaccine era may be useful to develop cost-effectiveness models and strategies and evaluate the impact of HPV vaccination in Spain.

    Because of the many therapeutic options available, a reliable staging is crucial for rectal neoplasia management. Adenomas and cancers limited to the submucosa without lymph node involvement may be treated locally. The aim of this study is to evaluate the diagnostic accuracy of endorectal ultrasonography in the staging of neoplasias suitable for local treatment. We considered all patients who underwent endorectal ultrasonography between 2001 and 2010. The study population consisted of 92 patients with 92 neoplasias (68 adenocarcinomas and 24 adenomas). A 5 and 7.5MHz linear array echoendoscope was used. The postoperative histopathologic result was compared with the preoperative staging defined by endorectal ultrasonography. Adenomas and cancers limited to the submucosa were considered together (pT0-1). The sensitivity, specificity, overall accuracy rate, positive predictive value, and negative predictive value of endorectal ultrasonography for pT0-1 were 86%, 95.6%, 91.3%, 94.9% and 88.7%. Those for nodal involvement were 45.4%, 95.5%, 83%, 76.9% and 84%, with 3 false positive results and 12 false negative. For combined pT0-1 and pN0, endorectal ultrasonography showed an 87.5% sensitivity, 95.9% specificity, 92% overall accuracy rate, 94.9% positive predictive value and 90.2% negative predictive value. Endorectal linear array ultrasonography is a reliable tool to detect rectal neoplasias suitable for local treatment. Copyright © 2011 Editrice Gastroenterologica Italiana S.r.l.

    The aim of this study was to elucidate risk factors for the development of colorectal neoplasia in the young population. In particular, we focused on the family history of gastric cancer. Young Japanese subjects aged 30-49 years old who underwent colonoscopy for the first time from August 2007 to August 2008 were included in this study. A total of 300 unselected consecutive patients (mean age 40.5 years) were eligible for analysis, and family history of colorectal cancer and gastric cancer, sex, age, body mass index, positivity of faecal occult blood test and the presence of symptoms were evaluated. Risk factors for developing colorectal adenoma and/or carcinoma were assessed. Colorectal neoplasias were detected in 83 (27.7%) cases. Two were found to have invasive carcinoma. Univariate and multivariate analyses revealed that family history of gastric cancer (OR 2.09, 95% CI 1.12-3.92, P = 0.02) was an independent risk factor for the development of colorectal neoplasia, as well as male sex (OR 1.89, 95% CI 1.10-3.27, P = 0.02), older age (OR 2.05, 95% CI 1.18-3.55, P = 0.01) and positive faecal occult blood test (OR 1.99, 95% CI 1.14-3.48, P = 0.02). In the young population under 50 years of age, a family history of gastric cancer is an independent risk factor for the development of colorectal neoplasia. © 2012 The Authors.

    Salivary, mammary and prostate glands are sex hormone-dependent organs sharing common aspects in structure, hormonal responsiveness and tumor histopathology. Salivary tumors (especially the malignant types) are not as frequent as mammary and prostate neoplasias. Hence, prognosis of some salivary tumors is not always efficient. Here, we review the oncology of salivary gland and its putative relation to breast/prostate tumors. PMID:17597843

    The Ras/Raf/Mek/Erk mitogen-activated protein kinase pathway regulates fundamental processes in normal and malignant cells, including proliferation, differentiation, and cell survival. Mutations in this pathway have been associated with carcinogenesis and developmental disorders, making Mek1 and Mek2 prime therapeutic targets. In this study, we examined the requirement for Mek1 and Mek2 in skin neoplasia using the two-step 7,12-dimethylbenz(a)anthraacene/12-O-tetradecanoylphorbol-13-acetate (...

    Heparanase 2 (HPSE2) is expressed in various tissues, including the brain, intestine, prostate, breast, and endometrium. The aim of this study was to investigate the role of HPSE2 in cervical carcinogenesis, which has not been clarified to date. The immunoexpression of HPSE2 in normal and neoplastic cervical squamous epithelia was determined using a semiquantitative (SQ) method and an index of expression (IE) method, using Image Lab Software. A total of 230 cervical tissue samples were analyzed and segregated into the following diagnostic groups: normal (27.4%), cervical intraepithelial neoplasia 1 (CIN 1, 15.2%), CIN 2 (16.5%), CIN 3 (15.2%), and invasive neoplasia (25.7%). The mean HPSE2 expression in the normal group was significantly lower than that of the other groups individually or combined (p < .001, for all combinations). The immunoexpression via the SQ method was significantly greater in the CIN 3 group compared with that in the CIN 1 group (p = .02). The mean immunoexpression of the high-grade squamous intraepithelial lesion groups was significantly greater than those of the normal and low-grade squamous intraepithelial lesion groups (p < .001) and lower compared with that of the invasive neoplasia group (p < .001). There were no statistically significant differences in the immunoexpression of HPSE2 among the different clinical states within the invasive neoplasia group. The SQ method produced a greater sensitivity and specificity than did the index of expression method. There was a progressive increase in the mean HPSE2 immunoexpression according to the severity of the cervical lesion from the low-grade squamous intraepithelial lesion group to the invasive neoplasm group, whereas the normal group displayed the lowest level of expression. This is a novel study concerning HPSE2 in the cervix and cervical cancer carcinogenesis.

  4. Development of thyroid neoplasia in old age in the Amazon molly, Poecilia formosa

    In a previous paper we have described the appearance of a thyrotrophin sensitive thyroid neoplasm in a few senile individuals from a laboratory population of guppies, Lebistes reticulatus (Peters). Material has now been examined from the closely related species, Poecilia formosa, the Amazon molly, in which the incidence of thyroid neoplasms in the senile fish of our clones approaches 100 percent. The spontaneous growth seen in the old mollies was large, occupying much of the pharyngeal region. It was formed of three zones; at the center were inactive follicles with flattened epithelial cells enclosing a dense uneroded colloid. Peripherally, there was an area which microfollicles predominated, and the follicular epithelial cells frequently were swollen and balloon-like. The outermost area of the growth contained many afollicular groups of epithelial cells, lying amongst a great deal of loose connective tissue. The thyroid tissue was invasive, destroying muscle and bone. We have suggested that the spontaneous thyroid neoplasia in old P. formosa and L. reticulatus arise in a similar way. They develop as a result of the inability of the aging thyroid to respond to thyrotrophic hormone. Under continued pituitary stimulation the thyroid cells greatly proliferate and hypertrophy, and form a neoplasia. The appearance is described of massive thyroid growths which were experimentally induced by the injection into young mollies of cells with damaged DNA. There were striking differences between the induced and the spontaneous thyroid growths. The neoplasia of old fish was highly variable in structure, but the induced neoplasia had a regular appearance. Neoplastic tissue closely resembled normal thyroid tissue--but the growth was exuberant and highly invasive. We suggest that the differences between the neoplasm of old age and the induced neoplasm may reflect a different hormonal status.

  6. DCIS and LCIS are confusing and outdated terms. They should be abandoned in favor of ductal intraepithelial neoplasia (DIN) and lobular intraepithelial neoplasia (LIN).

    2013-08-01

    The terms ductal and lobular intraepithelial neoplasia (DIN and LIN) were introduced by Tavossoli 15 years ago, who proposed they should replace, respectively, ductal and lobular carcinoma in situ (DCIS and LCIS). This proposal has been slowly gaining ground. We argue that DCIS and LCIS should now be definitively abandoned. Bringing together 'in situ' and other entities into the simpler and more logical DIN/LIN framework--as has been done with intraepithelial neoplasias of cervix, vagina, vulva, prostate, and pancreas--would eliminate the artificial and illogical distinctions between 'not cancers' (e.g. flat epithelial atypia, atypical ductal hyperplasia--now classified as low grade DIN) and 'cancers' (e.g. DCIS--now considered medium-high grade DIN). Elimination of the term 'carcinoma' from entities that cannot metastasize will reduce confusion among health professionals and patients, and contribute to reducing the risk of overtreatment, as well as reducing adverse psychological reactions in patients.

    Full Text Available Purpose: Women with human papilloma virus (HPV associated cervical neoplasia have a higher risk of developing breast cancer than the general female population. The purpose of this study was to (i identify high risk for cancer HPVs in cervical neoplasia and subsequent HPV positive breast cancers which developed in the same patients and (ii determine if these HPVs were biologically active.Methods: A range of polymerase chain reaction (PCR and immunohistochemical techniques were used to conduct a retrospective cohort study of cervical precancers and subsequent breast cancers in the same patients. Results: The same high risk HPV types were identified in both the cervical and breast specimens in 13 (46% of 28 patients. HPV type 18 was the most prevalent. HPVs appeared to be biologically active as demonstrated by the expression of HPV E7 proteins and the presence of HPV associated koilocytes. The average age of these patients diagnosed with breast cancer following prior cervical precancer was 51 years, as compared to 60 years for all women with breast cancer (p for difference = 0.001. Conclusions: These findings indicate that high risk HPVs can be associated with cervical neoplasia and subsequent young age breast cancer. However these associations are unusual and are a very small proportion of breast cancers. These outcomes confirm and extend the observations of 2 similar previous studies and offer one explanation for the increased prevalence of serious invasive breast cancer among young women.

    The incidence of intraepithelial anal neoplasia is increasing in certain risk behaviour groups, and human papillomavirus (HPV) infection is involved in its pathogenesis. The systematic use of anal cytology, and more recently HPV detection by hybrid capture and genotyping, have been introduced into screening programs in recent decades. A retrospective cohort study was carried out on individuals with risk behaviours of developing intraepithelial anal neoplasia and who attended Sexually Transmitted Infections clinics in the Dermatology area of the Hospital Costa del Sol from January 2010 to December 2012. The intraepithelial anal neoplasia screening was performed using anal cytology and HPV genotyping. Half (50%) of the study population were HIV positive. A high frequency of anal dysplasia and presence of HPV in cytology (82.1%) and genotype (79%) was found. A statistically significant association (P<.005) was obtained between the presence of high-risk HPV genotypes and the presence of high-grade dysplasia in the second directed cytology. HPV genotyping enabled 17 cases (22%) of severe dysplasia to be identified that were under-diagnosed in the first cytology. Cases of high-grade dysplasia can be under-diagnosed by a first anal cytology. Detection of HPV can supplement this procedure, leading to the identification of those patients most at risk of developing high-grade anal dysplasia.

    Synchronous colorectal neoplasias are defined as 2 or more primary tumors identified in the same patient and at the same time. The most voluminous synchronous cancer is called "first primitive" or "index" cancer. The aim of this work is to describe our experience of minimally invasive approach in patients with synchronous colorectal neoplasias.Since January 2001 till December 2009, 557 patients underwent colectomy for colorectal cancer at the Department of General and Emergency Surgery of the University of Perugia; 128 were right colon cancers, 195 were left colon cancers while 234 patients were affected by rectal cancers. We performed 224 laparoscopic colectomies (112 right, 67 left colectomies and 45 anterior resections of rectum), 91 Transanal Endoscopic Microsurgical Excisions (TEM) and 53 Trans Anal Excisions (TAE). In the same observation period 6 patients, 4 males and 2 females, were diagnosed with synchronous colorectal neoplasias. Minimal invasive treatment of colorectal cancer offers the opportunity to treat two different neoplastic lesions at the same time, with a shorter post-operative hospitalization and minor complications. According to our experience, laparoscopy and TEM may ease the treatment of synchronous diseases with a lower morbidity rate.

    To evaluate the oncological safety and pregnant outcomes of fertility-sparing uterine lesion resection in treating gestational trophoblastic neoplasias. After the treatment of surgery and chemotherapy, all the patients achieved complete remission. With a median follow-up time of 44 months (range, 6-188), 3 patients (3.85%) relapsed within 3-26 months. Multivariate analysis showed that tumor size was the independent risk factor of recurrence and the cutoff value was 4.2cm. Among 37 patients who attempted to conceive, 31 achieved clinical pregnancy. The rate of pregnancy and live birth were 83.8% and 77.4%. Uterine rupture did not occurred no matter in cesarean section or vaginal delivery. No congenital abnormalities were reported among the live births. From January 1995 to December 2014, 78 patients with gestational trophoblastic neoplasias who underwent fertility-sparing uterine lesion resection at Peking Union Medical College Hospital were reviewed. The complete remission rate, fertility rate, pregnant outcomes and risk factors of recurrence were analyzed. Fertility-sparing uterine lesion resection might be considered as a safe and reasonable alternative for high-selected young women to remove uterine lesion in the treatment of gestational trophoblastic neoplasias.

    Neoplasia is uncommon in Turner syndrome, although there is some evidence that brain tumors are more common in Turner syndrome patients than in the general population. We describe a woman with Turner syndrome (45,X) with a meningioma, in whom a second neoplasia, basal cell carcinomas of the scalp and nose, developed five years later in the absence of therapeutic radiation. Together with 7 cases of Turner syndrome with meningioma from a population-based survey in the United Kingdom, and 3 other isolated cases in the literature, we review this small number of patients for evidence of risk factors related to Turner syndrome, such as associated structural anomalies or prior treatment. We performed histological and fluorescent in situ hybridization (FISH) of 22q (NF2 locus) analyses of the meningeal tumor to search for possible molecular determinants. We are not able to prove causation between these two entities, but suggest that neoplasia may be a rare associated medical problem in Turner syndrome. Additional case reports and extension of population-based studies are needed. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available Background: The development of noninvasive molecular imaging approaches has the potential to improve management of cancer. Methods: In this study, we demonstrate the potential of noninvasive topical delivery of an epidermal growth factor-Alexa 647 (EGF-Alexa 647 conjugate to image changes in epidermal growth factor receptor expression associated with oral neoplasia. We report a series of preclinical analyses to evaluate the optical contrast achieved after topical delivery of EGF-Alexa 647 in a variety of model systems, including cells, three-dimensional tissue cultures, and intact human tissue specimens using wide-field and high-resolution fluorescence imaging. Data were collected from 17 different oral cancer patients: eight pairs of normal and abnormal biopsies and nine resected tumors were examined. Results: The EGF-dye conjugate can be uniformly delivered throughout the oral epithelium with a penetration depth exceeding 500 µm and incubation time of less than 30 minutes. After EGF-Alexa 647 incubation, the presence of oral neoplasia is associated with a 1.5- to 6.9-fold increase in fluorescence contrast compared with grossly normal mucosa from the same patient with both wide-field and high-resolution fluorescence imaging. Conclusions: Results illustrate the potential of EGF-targeted fluorescent agents for in vivo molecular imaging, a technique that may aid in the diagnosis and characterization of oral neoplasia and allow real-time detection of tumor margins.

    Full Text Available Los mapas conceptuales son una técnica que se utiliza para obtener una representación visual de las ideas de una persona sobre un concepto o un conjunto de conceptos relacionados. Concretamente, en este trabajo, a través de una metodología cualitativa, analizamos los mapas conceptuales propuestos por 52 grupos de estudiantes de Maestro de Educación Primaria con el fin de averiguar las características de los mapas y el grado de adecuación de los contenidos que incluyen en lo que respecta a la enseñanza de la nutrición humana en el 3º ciclo de Educación Primaria. Los participantes cursaban Maestro de Educación Primaria, y la recogida de datos se realizó a través de una actividad formativa incluida en el tema ¿qué enseñar sobre Ciencias en Educación Primaria? Los resultados muestran que los mapas son una herramienta útil para trabajar en la formación docente pues permiten organizar, sintetizar y comunicar lo que saben los alumnos. Además, a través de este trabajo se observa que los estudiantes poseen destrezas aceptables a la hora de representar conceptos/ideas en un mapa conceptual, aunque el nivel de adecuación de los conceptos/ideas sobre nutrición humana y sus relaciones suele ser medio o bajo. Estos resultados constituyen una llamada de atención para la formación docente, tanto inicial como permanente, pues muestran la incapacidad de ésta para cambiar prioridades en lo que a la selección de contenidos se refiere.

    In this population-based register study our objective was to explore the association of cervical intraepithelial neoplasia, grade 1 and loop electrosurcigal excision procedure with preterm birth. Our population consisted of 4759 women diagnosed with cervical intraepithelial neoplasia, grade 1 during 1997-2009 and their 3021 subsequent deliveries analyzed by loop electrosurcigal excision procedure and parity. Hospital Discharge Register was used to identify women diagnosed for cervical intraepithelial neoplasia, grade 1 and these data were linked with the Medical Birth Register data. We calculated odds ratios with 95% confidence intervals. Cervical intraepithelial neoplasia, grade 1 patients with loop electrosurcigal excision procedure had 54 (6.7%) subsequent preterm births and the corresponding figure among cervical intraepithelial neoplasia, grade 1 patients without loop electrosurcigal excision procedure was 116 (5.2%). This results in odds ratios 1.31 (95% confidence interval 0.94-1.83). We assessed the risk before and after diagnosis of cervical intraepithelial neoplasia, grade 1 both for patients with loop electrosurcigal excision procedure (odds ratios 1.47, 95% confidence interval 1.05-2.06) and without loop electrosurcigal excision procedure (odds ratios 0.90, 95% confidence interval 0.71-1.13). An increased risk for preterm birth after diagnosis of cervical intraepithelial neoplasia, grade 1 and loop electrosurcigal excision procedure was observed. We also compared both groups to the background population in the Medical Birth Register. For cervical intraepithelial neoplasia, grade 1 patients without loop electrosurcigal excision procedure the risk for preterm birth was not increased (odds ratios 0.95, 95% confidence interval 0.76-1.21) whereas for cervical intraepithelial neoplasia, grade 1 patients treated with loop electrosurcigal excision procedure the risk for preterm birth was increased (odds ratios 1.45, 95% confidence interval 1.02-1.92).

These controversies may hamper the uptake of hormonal contraceptives. Objective: To determine the association between hormonal contraceptives and cervical neoplasia. Materials and methods: This was a case-control study in which Pap-smear results of 156 participants on hormonal contraceptives were compared with those of 156 participants on no form of modern contraception. Modern contraception is defined as the use of such contraceptives as condoms, pills, injectables, intrauterine devices, implants, and female or male sterilization. Those found to have abnormal cervical smear cytology results were subjected further to colposcopy. Biopsy specimens for histology were collected from the participants with obvious cervical lesions or those with suspicious lesions on colposcopy. The results were analyzed with descriptive and inferential statistics at a 95% level of confidence. Results: A total of 71 (45.5%, 60 (38.5%, and 25 (16.0% of the participants on hormonal contraceptives were using oral contraceptives, injectable contraceptives, and implants, respectively.

    2005-04-01

    Full Text Available INTRODUCTION: Urogenital neoplasias frequently progress with obstructive uropathy due to local spreading or pelvic metastases. The urinary obstruction must be immediately relieved in order to avoid deterioration in these patients. The percutaneous nephrostomy is a safe and effective method for relief the obstruction; however the indications of such procedures have been questioned in patients with poor prognosis. MATERIAL AND METHODS: A retrospective study was performed with 43 patients (29 female and 14 male with urogenital neoplasias who were undergoing percutaneous nephrostomy during a 54-month period. The median age was 52 years. The primary tumoral site was the uterine cervix in 53.5% of patients, the bladder in 23.3%, the prostate in 11.6% and other sites in 11.6%. RESULTS: Postoperative complications occurred in 42.3% of the patients. There was no procedure-related mortality. Thirty-nine per cent of the patients died during the hospitalization period due to advanced neoplasia. The mortality rate was higher in patients with prostate cancer (p = 0.006, in patients over 52 years of age (p = 0.03 and in those who required hemodialysis before the procedure (p = 0.02. Thirty-two per cent of the patients survived long enough to undergo some form of treatment focused on the primary tumor. The survival rate was 40% at 6 months and 24.2% at 12 months. The percentage of the lifetime spent in hospitalization was 17.7%. The survival rate was higher in patients with neoplasia of the uterine cervix (p = 0.007 and in patients with 52 years of age or less (p = 0.008. CONCLUSION: Morbidity was high in this patient group; however, the majority of patients could be discharged from hospital and followed at home. Patients under 52 years of age and patients with neoplasia of the uterine cervix benefited most from the percutaneous nephrostomy when compared to patients with hormone therapy-refractory prostate cancer, bladder cancer or over 52 years of age.

    Ulcerative colitis (UC) promotes cancer, and can be ameliorated by early appendicectomy for appendicitis. The aim of the study was to explore the effect of appendicectomy on colitis and colonic neoplasia in an animal model of colitis and a cohort of patients with UC. Five-week old IL10/Nox1(DKO) mice with nascent colitis and 8-week-old IL10/Nox1(DKO) mice with established colitis underwent appendicectomy (for experimental appendicitis or no appendicitis) or sham laparotomy. The severity and extent of colitis was assessed by histopathological examination, and a clinical disease activity score was given. From a cohort of consecutive patients with UC who underwent colectomy, the prevalence of appendicectomy and pathological findings were collected from two institutional databases. Appendicectomy for appendicitis ameliorated experimental colitis in the mice; the effect was more pronounced in the 5-week-old animals. Appendicectomy in the no-appendicitis group was associated with an increased rate of colonic high-grade dysplasia (HGD) or cancer compared with rates in sham and appendicitis groups (13 of 20 versus 0 of 20 and 0 of 20 respectively; P UC had previously had an appendicectomy, and nine of these had colonic cancer or HGD. Thirty (13·8 per cent) of 217 patients with the appendix in situ had colonic neoplastic lesions. Multivariable analysis showed that previous appendicectomy was associated with colorectal neoplasia (odds ratio 16·88, 95 per cent c.i. 3·32 to 112·69). Appendicectomy for experimental appendicitis ameliorated colitis. The risk of colorectal neoplasia appeared to increase following appendicectomy without induced appendicitis in a mouse model of colitis, and in patients with UC who had undergone appendicectomy. Surgical relevance Appendicectomy for appendicitis protects against UC. In this murine model of colitis, appendicectomy for experimental appendicitis protected against colitis, but appendicectomy without appendicitis promoted

    Very little is known about risk factors associated with colorectal neoplasia in persons aged 49 years and to compare those data with those of persons aged 50 to 59 years. Cross-sectional observational study. Screening center in a university hospital in Korea. A cohort of 28,504 Korean adults (13,678 aged 30-39 years, 12,507 aged 40-49 years, and 2319 aged 50-59 years) who underwent colonoscopy as part of their routine preventive health care. Colonoscopy. Risk factors for colorectal neoplasia in persons aged 30 to 39 years and 40 to 49 years. In the 30-to-39-years group, male sex, smoking, fatty liver, metabolic syndrome (MetS), obesity, elevated fasting blood glucose levels, and elevated triglyceride levels were associated with overall neoplasia, whereas for advanced neoplasia, the independent risk factors were smoking, fatty liver, and elevated triglyceride levels. Moreover, the prevalence of overall neoplasia in men aged 30 to 39 years exhibiting all risk factors was not lower than that in average-risk women aged >50 years (20.8% vs 18.8%; P = .546). The risk factors of overall neoplasia in the 40-to-49-years group were similar to those in the 30-to-39-years group. For advanced neoplasia, the independent risk factors in the 40-to-49-years group were male sex, smoking, MetS, and obesity. Selection bias may exist for participants of ethnic Korean heritage in 2 centers. Obese male smokers with fatty liver and MetS might benefit from screening colonoscopy starting before age 50 years.

    2012-06-01

    Full Text Available Abstract Background The pathogenesis of colorectal neoplasia is still unresolved but has been associated with alterations in epithelial clearance of xenobiotics and metabolic waste products. The aim of this study was to functionally characterize the transport of cyclic nucleotides in colonic biopsies from patients with and without colorectal neoplasia. Methods Cyclic nucleotides were used as model substrates shared by some OATP- and ABC-transporters, which in part are responsible for clearance of metabolites and xenobiotics from the colonic epithelium. On colonic biopsies from patients with and without colorectal neoplasia, molecular transport was electrophysiologically registered in Ussing-chamber set-ups, mRNA level of selected transporters was quantified by rt-PCR, and subcellular location of transporters was determined by immunohistochemistry. Results Of four cyclic nucleotides, dibuturyl-cAMP induced the largest short circuit current in both patient groups. The induced short circuit current was significantly lower in neoplasia-patients (p = 0.024. The observed altered transport of dibuturyl-cAMP in neoplasia-patients could not be directly translated to an observed increased mRNA expression of OATP4A1 and OATP2B1 in neoplasia patients. All other examined transporters were expressed to similar extents in both patient groups. Conclusions OATP1C1, OATP4A1, OATP4C1 seem to be involved in the excretory system of human colon. ABCC4 is likely to be involved from an endoplasmic-Golgi complex and basolateral location in goblet cells. ABCC5 might be directly involved in the turnover of intracellular cAMP at the basolateral membrane of columnar epithelial cells, while OATP2B1 is indirectly related to the excretory system. Colorectal neoplasia is associated with lower transport or sensitivity to cyclic nucleotides and increased expression of OATP2B1 and OATP4A1 transporters, known to transport PGE2.

    Full Text Available La atención primaria en España ha pasado de una etapa de desarrollo florido, en la década de los ochenta, a otra de estancamiento en los noventa, caracterizada por la escasa creatividad, por la rutinización de las tareas y por la puesta en marcha de carteras de servicios y contratos programa. Por otra parte, los recientes cambios en la orientación de la investigación promovida desde la administración sanitaria, a favor de la investigación básica y en detrimento de la investigación en servicios y la epidemiología clínica, contrastan con la importancia de la atención primaria como ámbito natural de abordaje de numerosos agentes causales y prácticas de riesgo para la salud. A pesar de estas limitaciones, la cultura de la investigación ya se ha instalado en un buen número de centros de salud y de farmacias, y la investigación en atención primaria ha ido teniendo una mayor presencia en las revistas científicas. Sin embargo, es necesario gestionar la investigación, también desde las estructuras de atención primaria, de manera específica y diferenciada, favoreciendo la priorización, la evaluación y la responsabilidad mediante fórmulas organizativas flexibles y sistemas de información específicos. Ello debería incluir fórmulas de contratación y de relación laboral flexibles, que permitan la dedicación a la investigación, siquiera a tiempo parcial, así como modelos de carrera profesional que reconozcan las actividades de investigación y docencia. Las asociaciones científicas y profesionales de la atención primaria tienen ante sí el reto de mantener proyectos de investigación activos, incrementar su presencia entre los profesionales, emitir su opinión ante los problemas del sector y reforzar su organización y comunicación.

    Full Text Available La responsabilidad de educar bajo modelos de sostenibilidad es tarea de todos. Conceptos como medio ambiente, ecología, entorno, ecosistema,… deben estar presentes en las enseñanzas del niño desde la más temprana edad. Así pues centramos nuestra práctica en la Educación Primaria con el objetivo de concienciar del detrimento medioambiental y fomentar actitudes y comportamientos favorables para el logro de un desarrollo sostenible. Para ello proponemos utilizar uno de los procedimientos artísticos que se realizan con menos frecuencia en el aula, el grabado y las técnicas de estampación. A través de procesos que fomentan el desarrollo de la atención, la percepción, la imaginación y la creatividad de forma responsable, trabajaremos las posibilidades tecnológicas que ofrecen las técnicas gráficas más novedosas, el uso de los fotopolímeros en el aula. La elaboración de dibujos para ser procesados con procedimientos “menos tóxicos” nos permitirá lograr conductas de sensibilización en cuanto a una educación ambiental para la sostenibilidad.

    Full Text Available El objetivo en la escuela primaria en Francia hoy es enseñar moral en términos puramente laicos. Esta es una tarea compleja y difícil ; primero porque la enseñanza de la moral requiere prescindir de referencias a cualquier clase de religión revelada y teología racional alguna y segundo porque es necesario expresar los conceptos morales en términos accesibles a los niños. Los conceptos morales se han identificado con los religiosos, pero moral y religión no son sinónimos, aquí se somete a discusión las diferencias entre ambas. Las dimensiones morales del comportamiento humano se han definido usando conceptos como "deber" "bueno" y "bien moral". En el artículo se reflexiona en torno a las relaciones entre moralidad y organización social. La enseñanza de las ideas morales debe poner en conexión la moral con algo real, por ejemplo, la condición social con la sociedad.

    Full Text Available Se realizó una investigación sobre los pacientes con inmunodeficiencias primarias por déficit de anticuerpos, atendidos en el servicio de inmunología del Hospital General “Dr. Ernesto Guevara” de Las Tunas, con el objetivo de caracterizar las inmunodeficiencias por déficit de anticuerpos en pacientes adultos, atendiendo al tipo de inmunoglobulina afectada, el sexo y la edad, así como las principales manifestaciones clínicas. Se evaluaron un total de diez pacientes tratados por esta causa entre los años 2005 y 2013. Para la evaluación de los resultados se utilizó el análisis de frecuencias simple. Las inmunodeficiencias diagnosticadas se correspondieron en un 50% con el déficit de las tres clases de inmunoglobulinas. Predominó el sexo masculino en un 70% y las edades más afectadas se correspondieron con la cuarta y quinta décadas de la vida. Las infecciones respiratorias y digestivas fueron las más frecuentes (80%, tanto por gérmenes bacterianos como virales, la infección por Giardia lamblia también apareció muy frecuentemente en los pacientes estudiados
