    Full Text Available Este texto discute a importância da brincadeira infantil para o desenvolvimento da linguagem oral nas crianças. É o desdobramento de pesquisa que investigou o trabalho com a linguagem em uma instituição educativa infantil que atende crianças de 2 a 6 anos de idade. O estudo de caso utilizou como técnica de coleta dos dados a observação participante. Conclui que as crianças recriam, nas brincadeiras, situações vivenciadas nas diversas esferas de comunicação humana das quais participam e, portanto, que as brincadeiras são de natureza cultural. Acentua, ainda, a importância do trabalho colaborativo para o desenvolvimento infantilThis paper discusses the importance of children's play in the development of oral language. It is the unfolding of a research whose aim was to assess language acquisition by 2 to 6 year-old children enrolled at an early childhood education institution. This case study uses participant observation as a data collection method. It concludes that, while playing, children recreate the situations they experience in the diverse spheres of human communication in which they take part and, therefore, their playing activities are cultural in nature. It further stresses the importance of collaborative work in child development

  2. Enjuagues de Calendula officinalis como alternativa de los antisépticos orales

    Directory of Open Access Journals (Sweden)

    Luis Fang Mercado

    Full Text Available En la progresión de la enfermedad periodontal intervienen múltiples factores, incluyendo los diversos microorganismos orales que conforman la placa bacteriana o patógenos libres en cavidad oral que logran desencadenar una respuesta inmunológica e inflamatoria en el huésped. Existen herramientas químicas que combaten cualquier posibilidad de colonización e infección por parte de algún microorganismo. Los antisépticos orales son de gran utilidad especialmente luego de cirugías periodontales. Es allí donde su importancia se hace casi imprescindible, para controlar la noxa, pero a su vez deben facilitar el proceso de cicatrización de los tejidos involucrados. El objetivo del presente manuscrito consistió en reportar y describir un caso clínico donde el empleo de clorhexidina al 0,12 % como antiséptico oral postoperatorio no favoreció la cicatrización adecuada de los tejidos mucosos luego de realizarse un injerto gingival libre. Como alternativa antiséptica se prescribieron enjuagues a base de Caléndula, observándose cicatrización de los tejidos afectados a los pocos días de uso. Se discute que posterior a todo proceso operatorio de carácter quirúrgico se debe colocar en una balanza riesgo-beneficio, donde se escoge la posibilidad de evitar la infección posoperatoria o la cicatrización oportuna de esta. Los enjuagues orales de caléndula permitieron la cicatrización oportuna; los colutorios de caléndula contemplan una pequeña proporción de capacidad antimicrobiana y una alta habilidad inductora de la cicatrización tisular.

    Full Text Available The material presented discloses a topic of great value and current importance in the context of Pedagogy and Educative Psychology: the storytelling for children. It is intended for those teachers, who before the imminence and fast pace of daily life, are aware of the value of the communication, participation and conversation as resources that enhance the imagination. The purpose of this material is to stimulate the reflection and creativity of teachers to enable the development of storytelling skill in groups of boys and girls, based on the communicative approach, through which is acknowledged that in the storytelling, as a communicative act, the communicative elements that are involved in communication are present.

    Antineoplastic treatment induces some undesirable consequences in head and neck cancer patients. Often, the emergence of major clinical manifestations, such as oral mucositis, results in temporary interruption of the treatment, decreasing the patients' quality of life, and increasing hospital costs. Radio-induced or chemo-induced oral mucositis is possibly aggravated by opportunist fungal infections, which turn the mucositis more resistant to the conventional treatments. Objective: this study aims to identify the presence of Candida sp. as a possible aggravating factor of oral mucositis in patients with head and neck cancer under antineoplastic treatment. Method: all patients with radio- or chemo-induced oral mucositis from the Cancer Hospital of Pernambuco, treated between October 2008 and April 2009, were selected for the study. The prevalence of Candida sp was measured through the cytological analysis of oral mucosa in patients with oral mucositis. The fungal presence was correlated with the mucositis severity. Results: the results showed a positive association between fungal colonization and more several lesions (degrees III and IV of mucositis). Conclusion: The outcomes shown may contribute to a solution for unconventional mucosites, which do not respond to the usual treatment. (author)

    Full Text Available Existe amplia controversia acerca del mecanismo de acción del levonorgestrel como anticonceptivo oral de emergencia; numerosas organizaciones, tanto científicas como de la sociedad civil, muestran su disconformidad con su uso, debido a su posible acción como inductor de aborto. Con el objetivo de evaluar la evidencia científica disponible sobre los mecanismos de acción del levonorgestrel utilizado como anticonceptivo oral de emergencia (AOE, se realizó una revisión sistemática en las bases de datos Medline y Cochrane Library donde se encontró 444 artículos; después de revisar los resúmenes, se seleccionó 22 artículos, los cuales fueron evaluados a texto completo. Se encontró que el principal mecanismo de acción del levonorgestrel, a las dosis recomendadas como AOE, es la inhibición o retraso de la ovulación; no afecta a los espermatozoides en su capacidad de migración ni de penetración al óvulo. No se ha demostrado alteraciones morfológicas ni moleculares en el endometrio que puedan interferir con la implantación del huevo fecundado. No existe evidencia científica actual disponible que sustente que el uso de levonorgestrel como AOE sea abortivo.There is wide controversy about the mechanism of action of the levonorgestrel used for emergency oral contraception, and many organizations, both scientific as well as from the civil society, show their discrepancy with its use, due to its possible action as an abortion- inducer.

    Full Text Available Objetivando analisar a disseminação das artes marciais chinesas no Brasil optamos por entrevistar mestres pioneiros que imigraram da China trazendo na bagagem o "Kung Fu". Ao fazer esta opção em nossa dissertação, tomamos contato com um instrumental que é o uso de entrevistas na perspectiva da História Oral. Remexer a memória, aceitar os silêncios, respeitar o conhecimento construído e desconstruir outros, por si só já se mostram tarefas bastante árduas. Escutar estes mestres nos levou, mesmo que superficialmente, a tentar compreender aspectos da cultura chinesa sob os quais os mestres e o próprio "Kung Fu" se fundamentaram. Entender as lacunas, as dificuldades e as possibilidades do uso da História Oral como ferramenta metodológica é o que neste artigo buscamos, na perspectiva de contribuir com análises semelhantes, seja de outras práticas marciais ou mesmo de outros olhares sobre a cultura chinesa. Assim sendo, objetivamos neste artigo apontar e discutir a metodologia da História Oral e sua pertinência para o estudo das práticas marciais a partir do uso de entrevistas. Podemos, fruto da discussão apresentada, apontar a História Oral como instrumental bastante útil para a discussão das práticas marciais, considerando logicamente, as pertinências e especificidades necessárias para a adequada utilização desta metodologia de pesquisa.

Na segunda etapa do trabalho, desenvolveu-se uma proposta de intervenção e tratamento dos erros mais recorrentes, por meio da qual se pretendia implementar ações pedagógicas com foco na forma (FonF que promovessem a negociação de determinados aspectos lingüísticos. Os dados foram coletados por meio de entrevistas, questionários, gravações audiovisuais, observações das aulas, notas de campo transformadas em diários, sessões de visionamento com os aprendizes e de discussão com a professora participante, num processo cíclico e contínuo, a fim de se embasarem as decisões referentes ao processo interventivo. Verificou-se que os movimentos corretivos empregados para promover momentos de negociação da forma se mostraram uma importante ferramenta no tratamento dos erros por ajudarem os aprendizes a perceberem lacunas em suas interlínguas e a se esforçarem para refazer suas produções consideradas imprecisas. Nesse esforço, observou-se a importância do papel do professor ao fornecer os andaimes necessários para que cada aprendiz pudesse se monitorar. Considerou-se, também, a relevância do aspecto complementar entre os dois focos - foco na forma x foco na mensagem para o processo de ensino e aprendizagem de língua estrangeira por instrução.This study was carried out in order to investigate error management in EFL (English as a foreign language classes and its implications for the teaching and learning process.

MÉTODOS: foi realizado estudo retrospectivo de 49 prontuários de pacientes com disfagia neurogênica, atendidos em fonoterapia no leito hospitalar e comparada a escala de ingestão de alimentação por via oral antes e depois da terapia - FOIS, (mede a quantidade e tipo de alimento que o paciente consegue ingerir por via oral de forma segura. Foram estudados também possíveis fatores de interferência na melhora via ingestão oral na fonoterapia como: doença de base, idade, condições respiratórias, condições clínicas, estado de consciência, tempo de terapia e número de sessões. RESULTADOS: dos 49 pacientes, 36 apresentaram melhora na FOIS após a fonoterapia. Quanto aos possíveis fatores de interferência nessa melhora, foram constatados: a piora clínica do doente, as intercorrências clínicas e o rebaixamento do nível de consciência, como estatisticamente significantes para a não evolução em fonoterapia visando à ingestão de alimentos por via oral. Os outros fatores analisados como: doença de base, idade, condições respiratórias, tempo e numero de sessões não demonstraram significância estatística, sugerindo não interferir na melhora ou piora do paciente. CONCLUSÃO: observa-se melhora efetiva da ingestão de alimentos por via oral nos pacientes com disfagia neurogênica atendidos em ambiente hospitalar em fonoterapia, salvo se apresentarem intercorrências clínicas e rebaixamento do nível de consciência durante o processo.PURPOSE: to evaluate efficacy of speech therapy treatments and the interference of risk factors in adult patients admitted to the wards with neurological diseases and symptoms of dysphagia

O objetivo é expor: (a uma discussão do conceito de arquivo, expandindo os sentidos já existentes para o termo na teoria, e enfocando o caso dos dados que se referem à produção oral em língua inglesa, e (b relatar como a pesquisa tem lidado, até o momento, com os dados coletados, de maneira geral, e que constituem um corpus híbrido.  Em relação a (a, defende-se que a língua inglesa pode ser, ela mesma, considerada um arquivo que, no caso do curso analisado, é arquivo de si, em formato digital, um registro particular que pode ter efeitos particulares no processo de aprendizagem. Em relação a (b, expõe-se como os conceitos de regularidades enunciativas e funcionamento de paráfrase tem norteado a análise e possibilitado o que se propõe ser um mapeamento, unidade geral que mostre um funcionamento discursivo em acontecimento. O estudo pode contribuir tanto para a área da linguística aplicada ao ensino de línguas estrangeiras quanto para a teoria de análise de discurso.

    Full Text Available O conceito de auto-eficácia (AE foi introduzido em 1977 por BANDURA². Com ampla utilização na área de Saúde, ele tem se revelado um poderoso preditor em vários domínios de comportamentos, tais como: parar de fumar, perder peso, participar de programas de prevenção, entre outros. Este estudo investigou se uma intervenção psicológica produz melhora de índices clínicos em pacientes prestes a receberem tratamento odontológico. Previu-se que o grupo de teste (GT melhoraria mais do que o grupo de controle (GC nos índices clínicos de placa e sangramento e que a AE mediaria esta melhora. Os 30 participantes do GT, além do procedimento odontológico padrão, receberam uma intervenção psicológica baseada no modelo de PROCHASKA; DiCLEMENTE12 (1983. Os 30 participantes do GC receberam somente o procedimento odontológico padrão. Os resultados indicaram que os dois grupos apresentaram uma redução significativa dos índices clínicos do pré- para o pós-teste. Porém, os escores 2 e 3 de placa e sangramento sofreram um decréscimo significativamente maior no GT comparado ao GC (U = 197,00, p = 0,0001 e U = 179,00, p = 0,0001, respectivamente. Apenas o GT apresentou um incremento significativo na AE de pré- para pós-tratamento (Z = -3,58, p < 0,0001. No entanto, não houve diferença entre os grupos em termos de aumento de AE do pré- para o pós-teste. Concluindo, os resultados revelaram que a intervenção psicológica foi efetiva e sugerem a possibilidade de que outros fatores além da AE medeiem a melhora significativa do GT em índices clínicos.

As crianças com paralisia cerebral (PC também se beneficiam do uso do midazolam, mas seus efeitos são ainda desconhecidos sobre esse grupo de pacientes que apresentam uma série de particularidades, com alterações inclusive no local de ação do midazolam. O objetivo do estudo foi avaliar a ação do midazolam utilizado como medicação pré-anestésica sobre o índice bispectral (EEG-BIS dos pacientes com paralisia cerebral. MÉTODO: Foram avaliados dois grupos de pacientes: um com diagnóstico de PC e outro sem doença do sistema nervoso central (SNC e periférico. Foram registrados valores de EEG-BIS na enfermaria na véspera da operação e no dia da operação, 40 minutos depois da administração de 0,6 mg.kg-1 de midazolam via oral. Foram excluídos pacientes com história de reação paradoxal ao midazolam e pacientes do grupo-controle que estivessem em uso de outra medicação. RESULTADOS: Foram estudados 77 pacientes de ambos os sexos, entre 4 e 18 anos de idade. Não houve diferença entre os valores de EEG-BIS basal entre os grupos estudados. Após o uso do midazolam houve diminuição dos valores do EEG-BIS nos dois grupos estudados, com diferença estatística significativa em cada grupo. Na comparação entre grupos não houve diferença estatística. CONCLUSÕES: O midazolam administrado como medicação pré-anestésica na dose de 0,6 mg.kg-1 diminui os valores basais do EEG-BIS sem caracterizar hipnose e sem diferença estatística nos grupos estudados.JUSTIFICATIVA Y OBJETIVOS: El midazolam es un derivado benzodiazepínico con acción hipnótica y muy utilizado como medicación preanestésica en anestesia pediátrica.

    Full Text Available O objetivo desta revisão da literatura é discutir a importância da educação em saúde como estratégia de promoção de saúde bucal no período gestacional. Foram estudadas as manifestações bucais mais comuns na gestação, concluindo-se que, embora a gestação por si só não seja responsável por tais manifestações como, por exemplo, a cárie dentária e a doença periodontal, faz-se necessário o acompanhamento odontológico no pré-natal, considerando-se que as alterações hormonais da gravidez poderão agravar as afecções já instaladas. Destacou-se na promoção de saúde bucal na gestante a educação em saúde bucal, considerando-a parte importante do Programa de Atenção à Saúde da Mulher, conforme recomendado pelas atuais Diretrizes da Política Nacional de Saúde Bucal. Considera-se que, por meio de ações de educação em saúde bucal, desenvolvidas no pré-natal por uma equipe multiprofissional, orientada por um cirurgião-dentista, a mulher poderá se conscientizar da importância de seu papel na aquisição e manutenção de hábitos positivos de saúde bucal no meio familiar e atuar como agente multiplicador de informações preventivas e de promoção de saúde bucal.This literature revision is intended to discuss the importance of health education as a strategy to oral health promotion in the pregnancy period. The most common mouth manifestations during pregnancy have been studied, and the conclusion is that, although pregnancy itself is not responsible for such manifestations in the mouth, e.g. dental decay and periodontal diseases, a dentistry follow-up during prenatal care is necessary, considering that hormonal alterations in pregnancy may aggravate the diseases contracted. The oral health promotion for pregnant women has been focused on mouth health education, considering it an important part of the Program of Attention to Women's Health, as recommended by the current National Politics' Mouth Health

La propuesta que se hacía para controlar la situación era “la limitación de farmacias, con vigilancia estrecha del Estado y tarifa uniforme oficial”, así como “hace falta mucha inteligencia y mucha unión, hace falta que nadie permanezca indiferente, que todos y cada uno pongan de su parte lo que puedan”. Nuestra profesión mezcla una doble vertiente sanitaria y comercial que no siempre es fácil mantener equilibrada y, por lo que se ve, esto ha ocurrido así desde siempre. El problema que existe hoy en día es la mercantilización de la farmacia, un desplazamiento de establecimiento sanitario hacia una simple empresa.

Nem sempre são personagens que os ocupam, podem ser ideias, mas mesmo assim há um enredo conceitual que se passa. Modernamente, a forma dessa narrativa foi sobretudo o sistema, com a pretensão totalizadora presente, por exemplo, na filosofia de Hegel. Contemporaneamente, porém, a forma do ensaio – surgida ainda na era moderna – ganha destaque por sua forma descontínua de narrar. O objetivo do artigo é apontar que, se o ensaio é uma forma, como explicitaram Lukács, Benjamin e Adorno, ele é também uma forma de narrar – ainda que de narrar conceitualmente objetos da cultura.

    Full Text Available El artículo de Emmanuel Housset implica un esfuerzo de rehabilitación del concepto «persona» para la filosofía contemporánea y la fenomenología. Para ello el autor busca mostrar cómo poco a poco «persona» tomó otra significación que la de «personaje» o sujeto de derecho. Es en autores como san Agustín y santo Tomás de Aquino que se halla un acceso diferente que pone el énfasis más bien en su carácter relacional y responsivo de la persona, antes que en su dimensión autónoma y autotélica. Tal dimensión aparece, según Housset, junto con la idea de persona como creatura y en oposición a la de individuo racional dueño de sí. La dimensión afectiva, la personalidad despertada por las diversas figuras de la alteridad son algunas de las dimensiones de la persona que examina el autor a partir del examen de la carne, las pasiones, la memoria, la historicidad y el amor alteridad.Emmanuel Housset's paper is an effort to revitalize the concept of 'person' for contemporary philosophy and phenomenology To this end the author looks to show how little by little the understanding of 'person' took on a different meaning to that of 'character' or "right bearing individual". It is in authors such as St. Augustine and St. Thomas Aquinas that a different approach is found, one that puts emphasis on the relational and responsive character of a person, rather than on the autonomous and auto telic dimension. According to Housset, such a dimension appears together with the idea of the person as a creation, and in opposition to the idea of the rational individual, that is his own master. The emotional dimension and the personality that is awoken by the many figures of alterity are some of the dimensions of the person that the author analyzes, based on examining the flesh, passions, memory historicity and love.

    Full Text Available The aim of this article is to study the signs and symbols that appear in the hispanic medieval documents and manuscripts. These signs and symbols have usually been considered simply as mere elements to validate the charters. However, these alements were useful as a mean of visual communication between the high classes, able to generate charters, and the rest of medieval society—the majority illiterate— who received those charters. Because of their inability of understand an alphabetical code, they needed the graphic help to comprehend the message. Besides this, the article deals with non diplomatic signs and their function.

    Este artículo se centra en los signos o símbolos presentes en los documentos y manuscritos medievales hispanos, que habitualmente han sido tratados como meros elementos de validación de los diplomas. Pero estos elementos servían también de nexos de comunicación visual entre las clases poderosas, capaces de producir escritos, y los demás miembros de la sociedad medieval, receptores y destinatarios de tales escritos, en su mayoría analfabetos. Precisamente por esta razón, su incapacidad de descifrar un código alfabético, necesitan de auxilio gráfico para acercarse a la comprensión del mensaje. Asimismo, tratamos de los signos no diplomáticos y de su función.

  15. O analista como testemunha

    Directory of Open Access Journals (Sweden)

    Jô Gondar

    2016-04-01

    Full Text Available Resumo A proposta deste artigo é pensar o lugar da testemunha como um lugar terceiro que o analista, na clínica do traumático, é capaz de sustentar. Nos sonhos traumáticos, segundo Ferenczi, já existe a convocação de um terceiro. Não se trata da testemunha da esfera do Direito, tampouco do lugar do pai ou da Lei simbólica. Trata-se de um terceiro espaço que pode ser chamado de potencial, espaço intersticial, indeterminado e informe no qual circula - e aos poucos ganha forma -, algo que a princípio seria incomunicável. Esse espaço permite e suporta a literalidade da narrativa testemunhal, seus titubeios, paradoxos e silêncios. Mais do que uma teoria do trauma, a noção de espaço potencial seria a grande contribuição da psicanálise às pesquisas teóricas e clínicas com sobreviventes de campos de extermínio, de situações de tortura e de violência.

    Full Text Available Este artigo tem como ponto de partida o exemplo da relação espelhada entre um livro e uma pintura de mesmo nome: o retrato que Lucian Freud fez do crítico de arte Martin Gayford e o diário que esse crítico escreveu sobre seu retratista, ambas as obras chamadas Homem com cachecol azul. A partir do exemplo, discuto a metáfora do espelho para caracterizar a arte, recorrendo para isso à teoria da representação artísticas elaborada pelo filósofo norte-americano Arthur Danto no artigo “O mundo da arte”, de 1964, e no primeiro capítulo do livro A transfiguração do lugar-comum, de 1981. Recorro, por fim, a dois exemplos artísticos de espelhamento na representação analisados por Danto em O abuso da beleza, de 2003, um quadro holandês do século dezessete e um poema de Rainer Maria Rilke.

    Full Text Available Durante los últimos años el crecimiento mundial de catástrofes naturales ha ido en franco aumento. Sin embargo, desde un enfoque sistémico puede verificarse que la gran mayoría de los desastres se origina en los países en desarrollo (entre ellos los latinoamericanos, siendo las pérdidas en ellos significativamente más altas que en los países industrializados. Bajo esta postura los desastres no son sólo naturales sino socio- naturales, enfatizando la estrecha relación de causalidad entre modelos de desarrollo y urbanización y procesos de generación de riesgos, al incrementar la vulnerabilidad de los sectores más desprotegidos. El desastre pone en evidencia así una situación (la pobreza y segregación urbana ya existente, pero no considerada hasta el momento de la catástrofe. Frente a este panorama el desastre aparece como oportunidad que precipita tres catalizadores de políticas habitacionales: tierra, asistencia técnica y financiamiento, incrementando la celeridad y la creatividad de las respuestas. El interrogante que surge es por qué esperar el desastre para ponerlos en marcha, cuando ninguno de ellos es estrictamente dependiente de la situación de riesgo, sino sujeto de luchas de poder.

    1990-01-01

    In the U.S. oral cancer accounts for 2.1% of all cancers and 1% of cancer deaths. Two to three times as many males as females are affected. Blacks have more intra-oral cancer than whites, and their incidence and mortality rates have increased in recent years. The etiologic process very likely involves several factors. The major etiologic agents are tobacco (all types) and alcoholic beverages. Herpes simplex virus, human papilloma virus, and Candida have been implicated. Host factors include poor state of dentition, nutritional aberrations, cirrhosis of liver, lichen planus, and immunologic impairmant. Cellular changes include amplification of some oncogenes, alterations in antigen expression, production of gamma-glutamyl transpeptidase, and disturbance of keratin and involucrin production. Experimentally, cancer is readily produced on the hamster cheek pouch and rat oral mucosa. Unlike oral cancer in humans, most experimental lesions are exophytic, and they rarely metastasize.

We have also considered the obligatoriness of Law; giving the point of view of tadbruch who, explaining his ''Theory of the Obligatoriness of Law ", concluded that the obligatoriness of Law can only be withdraw when there is a Clash between morals, law, use and social conventions. We have looked at the notion of the imperativeness of Law the central theme of the work -drawing on the views of Miguel Reale, for whom the juridical nonn cannot be reduced to a "command of a volitional nature", but rather the obligatory character of the juridical nonn arises from the pressure of social values. Del Vecchio, who is also quoted, recognized that imperativeness exists in the juridical norm, whether it is preceptive (a positive command or permissive. Also mentioned is the opinion of Tercio Sampaio Ferraz, for whom the juridical norm has imperativeness to the extent that the imposition of behaviour is unconditionally guaranteed.

El día 15 de marzo de 2002, con motivo de la Cumbre Europea de Barcelona, Jorge Semprún reflexionaba, en las páginas de un conocido diario madrileño, sobre el significado que para él tenía ser europeo. Para ello emprendía tres "viajes intelectuales" a Viena, Praga y Buchenwald, los tres de gran significado histórico y cultural. Dado el interés del texto y del momento, me pareció entonces oportuno glosar algunos aspectos de aquel artículo, primero, para subrayar el valor de la aportación de Semprún, luego para corregir alguna inexactitud de carácter biográfico, debida posiblemente a la rapidez de la traducción, y, tercero, para ampliar con algún comentario la valiosa contribución de Sempnín, sobre todo en lo que concierne al sentido de Europa. En este texto se toma aquel comentario como punto de partida.The origins of this text are very specific. On 15 March 2002, on the occasion of the European Summit in Barcelona, and on the pages of a well-known Madrid newspaper, Jorge Semprún reflected on the meaning that being European had for him. To do this, he embarked on three "intellectual journeys" to Vienna, Prague and Buchenwald, all three of great historical and cultural significance. Given the interest of the text and of the moment, I considered it appropriate to comment on aspects of the article -firstly, to underline the value of Semprún's contribution; secondly, to correct certain biographical inaccuracies, possibly due to a hasty translation; and thirdly, to complement Semprún's valuable contribution, essentially concerning the meaning of Europe. This text takes that comment as its starting point.

    Oral candidiasis (OC) is a common fungal disease encountered in dermatology, most commonly caused by an overgrowth of Candida albicans in the mouth. Although thrush is a well-recognized presentation of OC, it behooves clinicians to be aware of the many other presentations of this disease and how to accurately diagnose and manage these cases. The clinical presentations of OC can be broadly classified as white or erythematous candidiasis, with various subtypes in each category. The treatments include appropriate oral hygiene, topical agents, and systemic medications. This review focuses on the various clinical presentations of OC and treatment options.

    Full Text Available Ronald C Hamdy,1,2 Dane N Daley11Osteoporosis Center, College of Medicine, East Tennessee State University, 2Veterans Affairs Medical Center, Johnson City, TN, USAAbstract: Calcitonin is a hormone secreted by the C-cells of the thyroid gland in response to elevations of the plasma calcium level. It reduces bone resorption by inhibiting mature active osteoclasts and increases renal calcium excretion. It is used in the management of postmenopausal osteoporosis, Paget's disease of bone, and malignancy-associated hypercalcemia. Synthetic and recombinant calcitonin preparations are available; both have similar pharmacokinetic and pharmacodynamic profiles. As calcitonin is a peptide, the traditional method of administration has been parenteral or intranasal. This hinders its clinical use: adherence with therapy is notoriously low, and withdrawal from clinical trials has been problematic. An oral formulation would be more attractive, practical, and convenient to patients. In addition to its effect on active osteoclasts and renal tubules, calcitonin has an analgesic action, possibly mediated through β-endorphins and the central modulation of pain perception. It also exerts a protective action on cartilage and may be useful in the management of osteoarthritis and possibly rheumatoid arthritis. Oral formulations of calcitonin have been developed using different techniques. The most studied involves drug-delivery carriers such as Eligen® 8-(N-2hydroxy-5-chloro-benzoyl-amino-caprylic acid (5-CNAC (Emisphere Technologies, Cedar Knolls, NJ. Several factors affect the bioavailability and efficacy of orally administered calcitonin, including amount of water used to take the tablet, time of day the tablet is taken, and proximity to intake of a meal. Preliminary results looked promising. Unfortunately, in two Phase III studies, oral calcitonin (0.8 mg with 200 mg 5-CNAC, once a day for postmenopausal osteoporosis and twice a day for osteoarthritis failed to

    Adequate dental and oral hygiene may become a challenge for all users and especially for elderly people and young children because of their limited motor skills. The same holds true for patients undergoing/recovering from chemo-/radiotherapy with accompanying sensitive mucosal conditions. Poor dental hygiene can result in tooth decay, gingivitis, periodontitis, tooth loss, bad breath (halitosis), fungal infection and gum diseases. The use of a toothbrush is the most important measure for oral hygiene. Toothbrushes with soft bristles operated carefully by hand or via an electric device help to remove plaque and to avoid mucosal trauma. A handlebar with a grip cover can be helpful for manually disabled patients or for those with reduced motor skills. In case of oral hygiene at the bedside or of patients during/after chemo-/radiotherapy a gauze pad can be helpful for gently cleaning the teeth, gums and tongue. The use of fluoride toothpaste is imperative for the daily oral hygiene. Detergents such as sodium lauryl sulphate improve the cleaning action but may also dehydrate and irritate the mucous membrane. The use of products containing detergents and flavouring agents (peppermint, menthol, cinnamon) should therefore be avoided by bedridden patients or those with dry mouth and sensitive mucosa. Aids for suitable interdental cleaning, such as dental floss, interdental brushes or dental sticks, are often complicated to operate. Their correct use should be instructed by healthcare professionals. To support dental care, additional fluoridation with a fluoride gel or rinse can be useful. Products further containing antiseptics such as chlorhexidine or triclosan reduce the quantity of bacteria in the mouth. For patients undergoing or having undergone radio-/chemotherapy, a mouthwash that concomitantly moisturizes the oral mucosa is advisable. Copyright © 2011 S. Karger AG, Basel.

    2010-01-01

    Full Text Available Oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents. The various type of oral sex practices are fellatio, cunnilingus and analingus. Oral sex is infrequently examined in research on adolescents; oral sex can transmit oral, respiratory, and genital pathogens. Oral health has a direct impact on the transmission of infection; a cut in your mouth, bleeding gums, lip sores or broken skin increases chances of infection. Although oral sex is considered a low risk activity, it is important to use protection and safer sex precautions. There are various methods of preventing infection during oral sex such as physical barriers, health and medical issues, ethical issues and oral hygiene and dental issues. The lesions or unhealthy periodontal status of oral cavity accelerates the phenomenon of transmission of infections into the circulation. Thus consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

    Oral cancer is one of the 10 most common cancers in the world, with a delayed clinical detection, poor prognosis, without specific biomarkers for the disease and expensive therapeutic alternatives. This review aims to present the fundamental aspects of this cancer, focused on squamous cell carcinoma of the oral cavity (OSCC), moving from its definition and epidemiological aspects, addressing the oral carcinogenesis, oral potentially malignant disorders, epithelial precursor lesions and experimental methods for its study, therapies and future challenges. Oral cancer is a preventable disease, risk factors and natural history is already being known, where biomedical sciences and dentistry in particular are likely to improve their poor clinical indicators.

    Oral cancer is considered as a serious health problem resulting in high morbidity and mortality. Early detection and prevention play a key role in controlling the burden of oral cancer worldwide. The five-year survival rate of oral cancer still remains low and delayed diagnosis is considered as one of the major reasons. This increases the demand for oral screening. Currently, screening of oral cancer is largely based on visual examination. Various evidence strongly suggest the validity of visual inspection in reducing mortality in patients at risk for oral cancer. Simple visual examination is accompanied with adjunctive techniques for subjective interpretation of dysplastic changes. These include toluidine blue staining, brush biopsy, chemiluminescence and tissue autofluorescence. This review highlights the efficacy of various diagnostic methods in screening of oral cancer. © 2016 Old City Publishing, Inc.

    Full Text Available RESUMEN: El artículo examina algunos usos y abusos de la lengua inglesa en la actualidad en el contexto de la globalización. Se define la neolengua, se ofrecen similitudes de la misma en el lenguaje publicitario en España, se trazan sus orígenes y se apuntan algunos antecedentes en la historia de la literatura inglesa, al tiempo que se ilustran ejemplos de variantes contemporáneas de la misma bajo la denominación de «nukespeak», especialmente abundantes en el discurso de los conflictos bélicos. La lengua inglesa está indisociablemente unida a complejos factores de orden económico, tecnológico y cultural que afectan a su misma morfología. Por otra parte, la presencia ubicua de la lengua inglesa, como idioma global, opera sobre las estructuras de sentimiento, pensamiento y acción de los ciudadanos en todo el mundo. Para los profesionales de la enseñanza del idioma inglés, ello comporta la obligación de discernir y resistir sus efectos potencialmente perversos al tiempo que siguen promoviendo sus valiosos beneficios culturales.ABSTRACT: Contemporary uses and abuses of the English language are examined in the context of complex issues and globalization trends. The term «newspeak» is defined, similitudes of it are found today in the language of advertising in Spain, its origins are traced back and antecedents are located in the history of English literature, while the presence of new modalities of the Orwellian reductionist language, such as «nukespeak», is illustrated within the language of warfare. The English language is inextricably bound up with economical, technological and cultural factors which affect its very morphology just as much as the pervasive influence of English as a global language affects the structures of feeling, thought and action of citizens all over the world, which poses an obligation on the part of EFL teachers to discern and resist its ill effects while they promote its still highly valuable cultural

  16. Oral biopsy: Oral pathologist′s perspective

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Many oral lesions may need to be diagnosed by removing a sample of tissue from the oral cavity. Biopsy is widely used in the medical field, but the practice is not quite widespread in dental practice. As oral pathologists, we have found many artifacts in the tissue specimen because of poor biopsy technique or handling, which has led to diagnostic pitfalls and misery to both the patient and the clinician. This article aims at alerting the clinicians about the clinical faults arising preoperatively, intraoperatively and postoperatively while dealing with oral biopsy that may affect the histological assessment of the tissue and, therefore, the diagnosis. It also reviews the different techniques, precautions and special considerations necessary for specific lesions.

    2018-02-01

    Mucosal involvement is commonly seen in patients with lupus; however, oral examination is often forgotten. Squamous cell carcinoma arising within oral lupoid plaques has been described, emphasizing the importance of identifying and treating oral lupus. We undertook a retrospective single-centre study looking at oral findings in patients attending our multidisciplinary lupus clinic between January 2015 and April 2016. A total of 42 patients were included. The majority of patients were female (88%) and had a diagnosis of discoid lupus erythematosus (62%). Half of the patients had positive oral findings, 26% had no oral examination documented, and 24% had documented normal oral examinations. Our findings suggest that oral pathology is common in this cohort of patients. Regular oral examination is warranted to identify oral lupus and provide treatment. Associated diseases such as Sjogren's syndrome may also be identified. Patients should be encouraged to see their general dental practitioners on a regular basis for mucosal review. Any persistent ulcer that fails to respond to treatment or hard lump needs urgent histopathological evaluation to exclude malignant transformation to squamous cell carcinoma.

  2. Towards understanding oral health.

    Science.gov (United States)

    Zaura, Egija; ten Cate, Jacob M

    2015-01-01

    During the last century, dental research has focused on unraveling the mechanisms behind various oral pathologies, while oral health was typically described as the mere absence of oral diseases. The term 'oral microbial homeostasis' is used to describe the capacity of the oral ecosystem to maintain microbial community stability in health. However, the oral ecosystem itself is not stable: throughout life an individual undergoes multiple physiological changes while progressing through infancy, childhood, adolescence, adulthood and old age. Recent discussions on the definition of general health have led to the proposal that health is the ability of the individual to adapt to physiological changes, a condition known as allostasis. In this paper the allostasis principle is applied to the oral ecosystem. The multidimensionality of the host factors contributing to allostasis in the oral cavity is illustrated with an example on changes occurring in puberty. The complex phenomenon of oral health and the processes that prevent the ecosystem from collapsing during allostatic changes in the entire body are far from being understood. As yet individual components (e.g. hard tissues, microbiome, saliva, host response) have been investigated, while only by consolidating these and assessing their multidimensional interactions should we be able to obtain a comprehensive understanding of the ecosystem, which in turn could serve to develop rational schemes to maintain health. Adapting such a 'system approach' comes with major practical challenges for the entire research field and will require vast resources and large-scale multidisciplinary collaborations. 2015 S.

  3. Global Oral Health Inequalities

    Garcia, I.; Tabak, L.A.

    2011-01-01

    Despite impressive worldwide improvements in oral health, inequalities in oral health status among and within countries remain a daunting public health challenge. Oral health inequalities arise from a complex web of health determinants, including social, behavioral, economic, genetic, environmental, and health system factors. Eliminating these inequalities cannot be accomplished in isolation of oral health from overall health, or without recognizing that oral health is influenced at multiple individual, family, community, and health systems levels. For several reasons, this is an opportune time for global efforts targeted at reducing oral health inequalities. Global health is increasingly viewed not just as a humanitarian obligation, but also as a vehicle for health diplomacy and part of the broader mission to reduce poverty, build stronger economies, and strengthen global security. Despite the global economic recession, there are trends that portend well for support of global health efforts: increased globalization of research and development, growing investment from private philanthropy, an absolute growth of spending in research and innovation, and an enhanced interest in global health among young people. More systematic and far-reaching efforts will be required to address oral health inequalities through the engagement of oral health funders and sponsors of research, with partners from multiple public and private sectors. The oral health community must be “at the table” with other health disciplines and create opportunities for eliminating inequalities through collaborations that can harness both the intellectual and financial resources of multiple sectors and institutions.

    Full Text Available Inflammation caused by infections may be the most important preventable cause of cancer in general. However, in the oral cavity the role of microbiota in carcinogenesis is not known. Microbial populations on mouth mucosa differ between healthy and malignant sites and certain oral bacterial species have been linked with malignancies but the evidence is still weak in this respect. Nevertheless, oral microorganisms inevitably up-regulate cytokines and other inflammatory mediators that affect the complex metabolic pathways and may thus be involved in carcinogenesis. Poor oral health associates statistically with prevalence of many types of cancer, such as pancreatic and gastrointestinal cancer. Furthermore, several oral micro-organisms are capable of converting alcohol to carcinogenic acetaldehyde which also may partly explain the known association between heavy drinking, smoking, poor oral health and the prevalence of oral and upper gastrointestinal cancer. A different problem is the cancer treatment-caused alterations in oral microbiota which may lead to the emergence of potential pathogens and subsequent other systemic health problems to the patients. Hence clinical guidelines and recommendations have been presented to control oral microbiota in patients with malignant disease, but also in this area the scientific evidence is weak. More controlled studies are needed for further conclusion.

    Symptomatic oral infection with Candida albicans is characterized by invasion of the oral epithelium by virulent hyphae that cause tissue damage releasing the inflammatory mediators that initiate and sustain local inflammation. Candida albicans triggers pattern-recognition receptors of keratinocytes, macrophages, monocytes and dendritic cells, stimulating the production of IL-1β, IL-6 and IL-23. These cytokines induce the differentiation of Th17 cells and the generation of IL-17- and/or IL-22-mediated antifungal protective immuno-inflammatory responses in infected mucosa. Some immune cells including NKT cells, γδ T cells and lymphoid cells that are innate to the oral mucosa have the capacity to produce large quantities of IL-17 in response to C. albicans, sufficient to mediate effective protective immunity against C. albicans. On the other hand, molecular structures of commensal C. albicans blastoconidia, although detected by pattern-recognition receptors, are avirulent, do not invade the oral epithelium, do not elicit inflammatory responses in a healthy host, but induce regulatory immune responses that maintain tissue tolerance to the commensal fungi. The type, specificity and sensitivity of the protective immune response towards C. albicans is determined by the outcome of the integrated interactions between the intracellular signalling pathways of specific combinations of activated pattern-recognition receptors (TLR2, TLR4, Dectin-1 and Dectin-2). IL-17-mediated protective immune response is essential for oral mucosal immunity to C. albicans infection. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2013-09-01

    Oral human papillomavirus (HPV) infection is the cause of 40% to 80% of oropharyngeal cancers; yet, no published study has examined the role of oral health in oral HPV infection, either independently or in conjunction with other risk factors. This study examined the relation between oral health and oral HPV infection and the interactive effects of oral health, smoking, and oral sex on oral HPV infection. Our analyses comprised 3,439 participants ages 30 to 69 years for whom data on oral HPV and oral health were available from the nationally representative 2009-2010 National Health and Nutrition Examination Survey. Results showed that higher unadjusted prevalence of oral HPV infection was associated with four measures of oral health, including self-rated oral health as poor-to-fair [prevalence ratio (PR) = 1.56; 95% confidence interval (CI), 1.25-1.95], indicated the possibility of gum disease (PR = 1.51; 95% CI, 1.13-2.01), reported use of mouthwash to treat dental problems in the past week (PR = 1.28; 95% CI, 1.07-1.52), and higher number of teeth lost (Ptrend = 0.035). In multivariable logistic regression models, oral HPV infection had a statistically significant association with self-rated overall oral health (OR = 1.55; 95% CI, 1.15-2.09), independent of smoking and oral sex. In conclusion, poor oral health was an independent risk factor of oral HPV infection, irrespective of smoking and oral sex practices. Public health interventions may aim to promote oral hygiene and oral health as an additional measure to prevent HPV-related oral cancers.

    High-grade gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs, G3) are aggressive cancers of the digestive system with poor prognosis and survival. Platinum-based chemotherapy (cisplatin/carboplatin + etoposide) is considered the first-line palliative treatment. Etoposide is frequently...... administered intravenously; however, oral etoposide may be used as an alternative. Concerns for oral etoposide include decreased bioavailability, inter- and intra-patient variability and patient compliance. We aimed to evaluate possible differences in progression-free survival (PFS) and overall survival (OS......) in patients treated with oral etoposide compared to etoposide given as infusion. Patients (n = 236) from the Nordic NEC study were divided into three groups receiving etoposide as a long infusion (24 h, n = 170), short infusion (≤ 5 h, n = 33) or oral etoposide (n = 33) according to hospital tradition.

  15. Maintaining women's oral health.

    Science.gov (United States)

    McCann, A L; Bonci, L

    2001-07-01

    Women must adopt health-promoting strategies for both general health and the oral cavity, because the health of a woman's body and oral cavity are bidirectional. For general health-maintenance strategies, dental practitioners should actively advise women to minimize alcohol use, abstain from or cease smoking, stay physically active, and choose the right foods to nourish both the body and mind. For oral health-maintenance strategies, dental practitioners should advise women on how to prevent or control oral infections, particularly dental caries and periodontal diseases. Specifically, women need to know how to remove plaque from the teeth mechanically, use appropriate chemotherapeutic agents and dentifrices, use oral irrigation, and control halitosis. Dental practitioners also need to stress the importance of regular maintenance visits for disease prevention. Adolescent women are more prone to gingivitis and aphthous ulcers when they begin their menstrual cycles and need advice about cessation of tobacco use, mouth protection during athletic activities, cleaning orthodontic appliances, developing good dietary habits, and avoiding eating disorders. Women in early to middle adulthood may be pregnant or using oral contraceptives with concomitant changes in oral tissues. Dental practitioners need to advise them how to take care of the oral cavity during these changes and how to promote the health of their infants, including good nutrition. Older women experience the onset of menopause and increased vulnerability to osteoporosis. They may also experience xerostomia and burning mouth syndrome. Dental practitioners need to help women alleviate these symptoms and encourage them to continue good infection control and diet practices.

  17. Oral vs. salivary diagnostics

    Science.gov (United States)

    Marques, Joana; Corby, Patricia M.; Barber, Cheryl A.; Abrams, William R.; Malamud, Daniel

    2015-05-01

    The field of "salivary diagnostics" includes studies utilizing samples obtained from a variety of sources within the oral cavity. These samples include; whole unstimulated saliva, stimulated whole saliva, duct saliva collected directly from the parotid, submandibular/sublingual glands or minor salivary glands, swabs of the buccal mucosa, tongue or tonsils, and gingival crevicular fluid. Many publications state "we collected saliva from subjects" without fully describing the process or source of the oral fluid. Factors that need to be documented in any study include the time of day of the collection, the method used to stimulate and collect the fluid, and how much fluid is being collected and for how long. The handling of the oral fluid during and post-collection is also critical and may include addition of protease or nuclease inhibitors, centrifugation, and cold or frozen storage prior to assay. In an effort to create a standard protocol for determining a biomarker's origin we carried out a pilot study collecting oral fluid from 5 different sites in the mouth and monitoring the concentrations of pro- and anti-inflammatory cytokines detected using MesoScaleDiscovery (MSD) electrochemiluminesence assays. Our data suggested that 3 of the cytokines are primarily derived from the submandibular gland, while 7 of the cytokines come from a source other than the major salivary glands such as the minor salivary glands or cells in the oral mucosae. Here we review the literature on monitoring biomarkers in oral samples and stress the need for determining the blood/saliva ratio when a quantitative determination is needed and suggest that the term oral diagnostic be used if the source of an analyte in the oral cavity is unknown.

  8. Ethnicity and oral cancer.

    Scully, C; Bedi, R

    2000-09-01

    Oral squamous-cell carcinoma, the main type of oral cancer, is among the ten most common cancers in the world. The aims of this paper were first, to consider whether there was evidence of marked ethnic variations in the incidence, management, and survival of oral cancer, and then, to review possible explanations for these variations. Evidence from the literature suggests that there is marked, inter-country variation in both the incidence and mortality from oral cancer. There is also growing evidence of intracountry ethnic differences, mostly reported in the UK and USA. These variations among ethnic groups have been attributed mainly to specific risk factors, such as alcohol and tobacco (smoking and smokeless), but dietary factors and the existence of genetic predispositions may also play a part. Variations in access to care services are also an apparent factor. The extent of ethnic differences in oral cancer is masked by the scarcity of information available. Where such data are accessible, there are clear disparities in both incidence and mortality of oral cancer between ethnic groups.

    Full Text Available INTRODUCTION: Oral Myiasis, a condition of infestation of the body by fly larvae (maggots is a rare pathology in humans. It is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It is seen frequently in tropical countries and hot climatic regions. The reported cases in literature of oral Myiasis associated with oral cancer are few. The treatment is a mechanical removal of the maggots but a systemic treatment with Ivermectin, a semi - synthetic macrolide antibiotic, has been used successfully for treatment for oral m yiasis. We present a case of 55 yr old male alcoholic patient with oral myiasis with extensive proliferative growth of oral cavity. Our patient was managed with manual debridement and administration of systemic ivermect in along with antibiotic coverage. Incisional biopsy of the proliferative lesion showed well differentiated squamous cell carcinoma. Thus our patient showed presence of oral myiasis in association with oral squamous cell carcinoma.

    Human oral bacteria interact with their environment by attaching to surfaces and establishing mixed-species communities. As each bacterial cell attaches, it forms a new surface to which other cells can adhere. Adherence and community development are spatiotemporal; such order requires communication. The discovery of soluble signals, such as autoinducer-2, that may be exchanged within multispecies communities to convey information between organisms has emerged as a new research direction. Direct-contact signals, such as adhesins and receptors, that elicit changes in gene expression after cell-cell contact and biofilm growth are also an active research area. Considering that the majority of oral bacteria are organized in dense three-dimensional biofilms on teeth, confocal microscopy and fluorescently labeled probes provide valuable approaches for investigating the architecture of these organized communities in situ. Oral biofilms are readily accessible to microbiologists and are excellent model systems for studies of microbial communication. One attractive model system is a saliva-coated flowcell with oral bacterial biofilms growing on saliva as the sole nutrient source; an intergeneric mutualism is discussed. Several oral bacterial species are amenable to genetic manipulation for molecular characterization of communication both among bacteria and between bacteria and the host. A successful search for genes critical for mixed-species community organization will be accomplished only when it is conducted with mixed-species communities. PMID:12209001

    Good oral health care during pregnancy is essential but often overlooked factor of dental growth as well as of other structures of oral cavity. Pregnancy is the time when conscious approach to preventive oral care should increase. Preventive measures during pregnancy mean usage of fluorides, special dietary measures and increased oral hygiene habits. Preventive measures in pregnant women have one goal: providing conditions for development of fetal teeth as well as preventing tooth decay in pregnant women. The optimal period for introducing preventive measures is the first trimester of pregnancy. Because of hormonal alterations there is an increased incidence of dental diseases: gingivitis and low salivary pH (inflammation and bleeding gums). Eating habits of pregnant women may lead to frequent snacking on candy or other decay-promoting foods, thereby increasing the risk of caries. However, very poor oral health, possible dental complications and their consequences to the health as well as emotional status represent very strong reasons for activation of dental health care in this period.

    The oral microbiota represents an important part of the human microbiota, and includes several hundred to several thousand diverse species. It is a normal part of the oral cavity and has an important function to protect against colonization of extrinsic bacteria which could affect systemic health. On the other hand, the most common oral diseases caries, gingivitis and periodontitis are based on microorganisms. While (medical) research focused on the planktonic phase of bacteria over the last 100 years, it is nowadays generally known, that oral microorganisms are organised as biofilms. On any non-shedding surfaces of the oral cavity dental plaque starts to form, which meets all criteria for a microbial biofilm and is subject to the so-called succession. When the sensitive ecosystem turns out of balance - either by overload or weak immune system - it becomes a challenge for local or systemic health. Therefore, the most common strategy and the golden standard for the prevention of caries, gingivitis and periodontitis is the mechanical removal of this biofilms from teeth, restorations or dental prosthesis by regular toothbrushing.

    Oral health care in pregnancy is often avoided and misunderstood by physicians, dentists, and patients. Evidence-based practice guidelines are still being developed. Research suggests that some prenatal oral conditions may have adverse consequences for the child. Periodontitis is associated with preterm birth and low birth weight, and high levels of cariogenic bacteria in mothers can lead to increased dental caries in the infant. Other oral lesions, such as gingivitis and pregnancy tumors, are benign and require only reassurance and monitoring. Every pregnant woman should be screened for oral risks, counseled on proper oral hygiene, and referred for dental treatment when necessary. Dental procedures such as diagnostic radiography, periodontal treatment, restorations, and extractions are safe and are best performed during the second trimester. Xylitol and chlorhexidine may be used as adjuvant therapy for high-risk mothers in the early postpartum period to reduce transmission of cariogenic bacteria to their infants. Appropriate dental care and prevention during pregnancy may reduce poor prenatal outcomes and decrease infant caries.

  9. Canine oral melanoma.

    Melanoma is the most common oral malignancy in the dog. Oral and/or mucosal melanoma has been routinely considered an extremely malignant tumor with a high degree of local invasiveness and high metastatic propensity. Primary tumor size has been found to be extremely prognostic. The World Health Organization staging scheme for dogs with oral melanoma is based on size, with stage I = or = 4cm tumor and/or lymph node metastasis, and stage IV = distant metastasis. Median survival times for dogs with oral melanoma treated with surgery are approximately 17 to 18, 5 to 6, and 3 months with stage I, II, and III disease, respectively. Significant negative prognostic factors include stage, size, evidence of metastasis, and a variety of histologic criteria. Standardized treatments such as surgery, coarse-fractionation radiation therapy, and chemotherapy have afforded minimal to modest stage-dependent clinical benefits and death is usually due to systemic metastasis. Numerous immunotherapeutic strategies have been employed to date with limited clinical efficacy; however, the use of xenogeneic DNA vaccines may represent a leap forward in clinical efficacy. Oral melanoma is a spontaneous syngeneic cancer occurring in outbred, immunocompetent dogs and appears to be a more clinically faithful therapeutic model for human melanoma; further use of canine melanoma as a therapeutic model for human melanoma is strongly encouraged. In addition, the development of an expanded but clinically relevant staging system incorporating the aforementioned prognostic factors is also strongly encouraged.

    Full Text Available Pyogenic granuloma is one of the inflammatory hyperplasias seen in the oral cavity. This term is a misnomer because the lesion is unrelated to infection and in reality arises in response to various stimuli such as low-grade local irritation, traumatic injury, or hormonal factors. It predominantly occurs in the second decade of life in young females, possibly because of the vascular effects of female hormones. Clinically, oral pyogenic granuloma is a smooth or lobulated exophytic lesion manifesting as small, red erythematous growth on a pedunculated or sometimes sessile base, which is usually hemorrhagic. Although excisional surgery is the treatment of choice , some other treatment protocols such as the use of Nd:YAG laser, flash lamp pulsed dye laser, cryosurgery, intralesional injection of ethanol or corticosteroids, and sodium tetradecyl sulfate sclerotherapy have been proposed. We present the case of a 25-year-old pregnant woman with large oral pyogenic granuloma.

    Oral health is affected by its resident microorganisms. Three prominent oral disorders are dental caries, gingivitis and periodontitis, with the oral microbiota playing a key role in the initiation/progression of all three. Understanding the microbiota and the diseases they may cause is critical to the development of new therapeutics. This review is focused on probiotics for the prevention and/or treatment of oral diseases. This review describes the oral ecosystem and its correlation with oral health/disease. The pathogenesis and current prevention/treatment strategies of periodontal diseases (PD) and dental caries (DC) are depicted. An introduction of probiotics is followed by an analysis of their role in PD and DC, and their potential role(s) in oral health. Finally, a discussion ensues on the future research directions and limitations of probiotics for oral health. An effective oral probiotic formulation should contribute to the prevention/treatment of microbial diseases of the oral cavity. Understanding the oral microbiota's role in oral disease is important for the development of a therapeutic to prevent/treat dental diseases. However, investigations into clinical efficacy, delivery/dose optimization, mechanism(s) of action and other related parameters are yet to be fully explored. Keeping this in mind, investigations into oral probiotic therapies are proving promising.

    Full Text Available Oral diseases are known to be closely associated with oral biofilm metabolism, while cancer tissue is reported to possess specific metabolism such as the ‘Warburg effect’. Metabolomics might be a useful method for clarifying the whole metabolic systems that operate in oral biofilm and oral cancer, however, technical limitations have hampered such research. Fortunately, metabolomics techniques have developed rapidly in the past decade, which has helped to solve these difficulties. In vivo metabolomic analyses of the oral biofilm have produced various findings. Some of these findings agreed with the in vitro results obtained in conventional metabolic studies using representative oral bacteria, while others differed markedly from them. Metabolomic analyses of oral cancer tissue not only revealed differences between metabolomic profiles of cancer and normal tissue, but have also suggested a specific metabolic system operates in oral cancer tissue. Saliva contains a variety of metabolites, some of which might be associated with oral or systemic disease; therefore, metabolomics analysis of saliva could be useful for identifying disease-specific biomarkers. Metabolomic analyses of the oral biofilm, oral cancer, and saliva could contribute to the development of accurate diagnostic, techniques, safe and effective treatments, and preventive strategies for oral and systemic diseases.

    Oral cavity squamous cell cancers form a significant percentage of the cancers seen in India. While clinical examination allows direct visualization, it cannot evaluate deep extension of disease. Cross-sectional imaging has become the cornerstone in the pretreatment evaluation of these cancers and provides accurate information about the extent and depth of disease that can help decide the appropriate management strategy and indicate prognosis. Early cancers are treated with a single modality, either surgery or radiotherapy while advanced cancers are offered a combination of surgery, radiotherapy and chemotherapy. Imaging can decide resectability, help plan the precise extent of resection, and indicate whether organ conservation therapy should be offered. Quality of life issues necessitate preservation of form and function and pretreatment imaging helps plan appropriate reconstruction and counsel patients regarding lifestyle changes. Oral cavity has several subsites and the focus of the review is squamous cancers of the gingivobuccal region, oral tongue and retromolar trigone as these are most frequently encountered in the subcontinent. References for this review were identified by searching Medline and PubMed databases. Only articles published in English language literature were selected. This review aims to familiarize the radiologist with the relevant anatomy of the oral cavity, discuss the specific issues that influence prognosis and management at the above subsites, the optimal imaging methods, the role of imaging in accurately staging these cancers and in influencing management. A checklist for reporting will emphasize the information to be conveyed by the radiologist

    2010-12-01

    On the 50th birthday of the pill, it is appropriate to recall the milestones which have led to its development and evolution during the last five decades. The main contraceptive effect of the pill being inhibition of ovulation, it may be called a small miracle that this drug was developed long before the complex regulation of ovulation and the menstrual cycle was elucidated. Another stumbling block on its way was the hostile climate with regard to contraception that prevailed at the time. Animal experiments on the effect of sex steroids on ovulation, and the synthesis of sex steroids and orally active analogues were the necessary preliminaries. We owe the development of oral contraceptives to a handful of persons: two determined feminists, Margaret Sanger and Katherine McCormick; a biologist, Gregory Pincus; and a gynaecologist, John Rock. Soon after the introduction of the first pills, some nasty and life-threatening side effects emerged, which were due to the high doses of sex steroids. This led to the development of new preparations with reduced oestrogen content, progestins with more specific action, and alternative administration routes. Almost every decade we have witnessed a breakthrough in oral contraception. Social and moral objections to birth control have gradually disappeared and, notwithstanding some pill scares, oral contraceptives are now one of the most used methods of contraception. Finally, all's well that ends well: recent reports have substantiated the multiple noncontraceptive health benefits paving the way for a bright future for this 50-year-old product.

  15. Oral Lichen Planus.

    Science.gov (United States)

    Ion, Daniela I; Setterfield, Jane F

    2016-02-01

    Lichen planus (LP) is a relatively common autoimmune T-cell-mediated disease of unknown aetiology affecting the mucous membranes, skin and nails. Its prevalence varies between 0.5 and 2.2% of the population in epidemiological studies with a peak incidence in the 30-60 years range and with a female predominance of 2:1. Mucosal lichen planus tends to follow a chronic course with acute exacerbations. Spontaneous remission of oral lichen planus (OLP) is uncommon, and indeed mucosal LP may become worse with time. In contrast, cutaneous lichen planus may follow a milder clinical course though some variants may be severe such as those affecting the palms and soles and the scalp and the genital tract in females (vulvovaginal gingival LP) where scarring leads to significant complications. It is important to identify those cases that may be drug induced or be associated with a contact allergic or irritant reaction (lichenoid reaction) or the rarer oral presentation of discoid lupus erythematosus. There is a very small risk of malignancy (approximately 1:200 patients/year) associated with oral lichen planus; thus patients should be informed that long term monitoring via their general dental practitioner is appropriate. This review will focus on the clinical presentation and management of oral lichen planus.

    Full Text Available 29 - year Lichen planus is a chronic, inflammatory, autoimmune skin disease, that is often manifested, except on the skin, in the oral cavity in a variety of clinical forms. The prevalence of the disease in the general population is about 1-2%. Etiopathogenesis is not still well understood. Histopathology, in addition to the basic methods, anamnesis and physical examination, is vital for proper diagnosis of oral lichen planus (OLP. Very diverse and loaded histological findings are common for all forms of oral lichen planus. We reported the case of oral lichen planus in a 49 years old male patient, who presented to the Dentistry clinic of Medical faculty of Priština with burning and itching symptoms and changes in the buccal mucosa. Histopathological analysis of biopsy tissue conformed clinical diagnosis of lichen planus. Due to the possibility for malignant transformation of lesions, the long-term follow-up of patients with this disease is of great importance.

  17. Antibiotics and oral contraceptives.

    Science.gov (United States)

    DeRossi, Scott S; Hersh, Elliot V

    2002-10-01

    With the exception of rifampin-like drugs, there is a lack of scientific evidence supporting the ability of commonly prescribed antibiotics, including all those routinely employed in outpatient dentistry, to either reduce blood levels and/or the effectiveness of oral contraceptives. To date, all clinical trials studying the effects of concomitant antibiotic therapy (with the exception of rifampin and rifabutin) have failed to demonstrate an interaction. Like all drugs, oral contraceptives are not 100% effective with the failure rate in the typical United States population reported to be as high as 3%. It is thus possible that the case reports of unintended pregnancies during antibiotic therapy may simply represent the normal failure rate of these drugs. Considering that both drug classes are prescribed frequently to women of childbearing potential, one would expect a much higher rate of oral contraceptive failure in this group of patients if a true drug:drug interaction existed. On the other hand, if the interaction does exist but is a relatively rare event, occurring in, say, 1 in 5000 women, clinical studies such as those described in this article would not detect the interaction. The pharmacokinetic studies of simultaneous antibiotic and oral contraceptive ingestion, and the retrospective studies of pregnancy rates among oral contraceptive users exposed to antibiotics, all suffer from one potential common weakness, i.e., their relatively small sample size. Sample sizes in the pharmacokinetic trials ranged from 7 to 24 participants, whereas the largest retrospective study of pregnancy rates still evaluated less than 800 total contraceptive users. Still, the incidence of such a rare interaction would not differ from the accepted normal failure rate of oral contraceptive therapy. The medico-legal ramifications of what looks like at best a rare interaction remains somewhat "murky." On one hand, we have medico-legal experts advising the profession to exercise caution

    Full Text Available A proposta deste artigo é uma reflexão sobre o tratamento dado à oralidade na educação infantil. Tomou-se, como referência, a forma como os contos de fadas são apresentados aos alunos, pêlos professores. Foi analisada a abordagem dada pelo Referencial Curricular para Educação Infantil (1998 à linguagem oral e escrita, bem como trechos de entrevistas realizadas com professores de educação infantil, em uma cidade do interior paulista, como parte de uma pesquisa que resultou na dissertação de Mestrado da autora. Como resultados, percebemos que a escola, em sua função alfabetizadora e por acreditar que as crianças provêm de um meio sócio-cultural desfavorecido, valoriza a linguagem escrita e despreza a oralidade, que perde sua função auxiliar na construção simbólica da criança, o que facilitaria o próprio processo de alfabetização.The aim of this paper is a reflection on the treatment given to orality in infant education. One takes as a reference the way fairy tales are presented to the students by the teachers. The approach given by the Standard Curriculum for Infant Education (1998 was analyzed in relation to oral and written language. Parts of interviews concerning the acquisition of literacy, made with infant education teachers in a city of the state of São Paulo, Brazil, and which were part of the research that resulted in the author’s MA dissertation, were also analyzed. The results of this research show that the school, believing that the children come from an unfavorable social-cultural environment, gives more weight to the written language to the detriment of oral language when teaching how to read. By being played down, orality loses its auxiliary function in the child’s symbolic construction which could help in the acquisition of literacy.

    2010-10-01

    Age-related oral changes are seen in the oral hard and soft tissues as well as in bone, the temporomandibular joints and the oral mucosa. As older patients retain their natural teeth for longer, the clinical picture consists of normal physiological age changes in combination with pathological and iatrogenic effects. Clinical Relevance: With an ageing population retaining more of its natural teeth for longer, dental professionals should expect to observe oral age changes more frequently.

  6. La entrevista como encuentro de subjetividades

    Directory of Open Access Journals (Sweden)

    Emma Ruiz Martín del Campo

    2003-01-01

    Full Text Available Se parte de la comprensión de la subjetividad como la expresión preñada de cultura de cada ser humano que se gesta en las relaciones interpersonales, primero entre el infante y las personas que le prodigan los cuidados tempranos, y después en la adolescencia y la edad adulta, con cada vez más representantes de la cultura de la socialización. En dicha interacción, la persona aprende a convivir con otros y a modelar sus impulsos, lo que le permite encontrar las formas más satisfactorias posibles de experimentarse a sí misma y tomar parte en las actividades de su entorno social. El equilibrio entre el individuo que busca satisfacer sus impulsos y necesidades y la cultura a la que pertenece es dinámico, por lo que la subjetividad se transforma a lo largo de toda la vida. Tras abundar sobre la subjetividad, se describen dos formas de orientar la entrevista a profundidad: la psicoanalítica y la etnopsicoanalítica. La entrevista psicoanalítica explora la subjetividad como tal y en ella el entrevistador actúa como un acompañante del sujeto en la progresiva comprensión de sí mismo y de su historia individual, desentrañando significados del comportamiento hasta entonces inconscientes para sí mismo, que se clarifican en la interacción. La entrevista etnopiscoanalítica busca explorar la experiencia cultural de las personas. Expertos en ciencias sociales entrenados a la vez en el descubrimiento del inconsciente se involucran en un medio cultural nuevo para ellos y a través de entrevistas y conversaciones con los integrantes de la comunidad que visitan van descubriendo formas de participación de estos en los espacios de vida social, así como las maneras que dan cuenta de símbolos y modos de reacción propios de su cultura. Cada una de estas dos formas de entrevista es ilustrada con un ejemplo que da muestra plásticamente del encuentro de las subjetividades

    2018-01-01

    There is a substantial proportion of the population using fixed metallic oral appliances, such as crowns and bridges, which are composed of various dental alloys. These restorations may be associated with a number of effects on oral health with variable degrees of severity, to review potential effects of using fixed metallic oral appliances, fabricated from various alloys. The MEDLINE/PubMed database was searched using certain combinations of keywords related to the topic. The search revealed that burning mouth syndrome, oral pigmentation, hypersensitivity and lichenoid reactions, and genotoxic and cytotoxic effects are the major potential oral health changes associated with fixed prosthodontic appliances. Certain oral disorders are associated with the use of fixed metallic oral appliances. Patch test is the most reliable method that can be applied for identifying metal allergy, and the simultaneous use of different alloys in the mouth is discouraged.

Marañón was, above all, a moralist in the Kantian sense, an autonomous person not governed by external criteria but by duty; a thinker convinced of the transforming role of the positive sciences, towards a happier and more just society through a deep intellectual reform. Marañón, like Fernando de los Rios, integrated Kraussism, neo-Kantianism and socialism and from this ideological platform sought the necessary moral change in the Spanish people.Marañón ha pasado a la historia del siglo XX como arquetipo, debido a su actitud coherente y a su “talante liberal”.

    Full Text Available Se trata de un artículo sobre la evolución histórica de la tecnología en neonatología, resaltando aspectos conceptuales y reflexivos sobre el impacto tecnológico en el proceso de cuidar. A pesar de que en los últimos años, la tecnología ha contribuido para mejorar la supervivencia de prematuros extremos nacidos con muy bajo peso, algunas veces da lugar a una modalidad de atención mecánica e impersonal, que se contrapone a cuestiones de índole ética y humana. Se propone una discusión crítica y reflexiva acerca del uso de la tecnología en el cuidado neonatal, destacando sus implicaciones y adecuaciones a las necesidades del recién nacido. Se concluyó que lo que determina si una tecnología es buena o mala, si deshumaniza, despersonaliza o interpreta como objeto al sujeto a cuidar, es la manera como es utilizada, convirtiéndose en imprescindible el perfeccionamiento y la actualización de los profesionales de la salud. En este ejercicio análitico es necesario reflexionar acerca de nuevas maneras de brindar cuidados, utilizando el arte, la sensibilidad y la creatividad en la adaptación y humanización de las tecnologías.

    2010-11-01

    This pilot study was performed to test the hypothesis that an orthodontic oral appliance (OA) that is designed to work against the backwardly directed forces on the upper incisors may counteract the reduction in overjet from these devices. Thirty patients with normal bites, good oral health, and milder sleep apnea were randomized to treatment with either OAs or orthodontic OAs. Bite changes were evaluated on plaster casts and radiographs and by questionnaires after a mean of 2.4 years in 19 frequent users. Four of nine patients in the orthodontic OA group increased their overjet by > or =0.4 mm, while none of the 10 patients in the OA group experienced that effect. Only the orthodontic OA increases the overjet; this design may therefore be beneficial to patients at risk of negative effects on their bite during OA treatment.

    Immune mediated diseases of oral cavity are uncommon. The lesions may be self-limiting and undergo remission spontaneously. Among the immune mediated oral lesions the most important are lichen planus, pemphigus, erythema multiformi, epidermolysis bullosa, systemic lupus erythematosis. Cellular and humoral mediated immunity play a major role directed against epithelial and connective tissue in chronic and recurrent patterns. Confirmatory diagnosis can be made by biopsy, direct and indirect immunoflouresence, immune precipitation and immunoblotting. Therapeutic agents should be selected after thorough evaluation of immune status through a variety of tests and after determining any aggravating or provoking factors. Early and appropriate diagnosis is important for proper treatment planning contributing to better prognosis and better quality of life of patient.

    The discovery during the first half of the 20th century of the link between natural fluoride, adjusted fluoride levels in drinking water and reduced dental caries prevalence proved to be a stimulus for worldwide on-going research into the role of fluoride in improving oral health. Epidemiological studies of fluoridation programmes have confirmed their safety and their effectiveness in controlling dental caries. Major advances in our knowledge of how fluoride impacts the caries process have led to the development, assessment of effectiveness and promotion of other fluoride vehicles including salt, milk, tablets, toothpaste, gels and varnishes. In 1993, the World Health Organization convened an Expert Committee to provide authoritative information on the role of fluorides in the promotion of oral health throughout the world (WHO TRS 846, 1994). This present publication is a revision of the original 1994 document, again using the expertise of researchers from the extensive fields of knowledge required to successfully implement complex interventions such as the use of fluorides to improve dental and oral health. Financial support for research into the development of these new fluoride strategies has come from many sources including government health departments as well as international and national grant agencies. In addition, the unique role which industry has played in the development, formulation, assessment of effectiveness and promotion of the various fluoride vehicles and strategies is noteworthy. This updated version of 'Fluoride and Oral Health' has adopted an evidence-based approach to its commentary on the different fluoride vehicles and strategies and also to its recommendations. In this regard, full account is taken of the many recent systematic reviews published in peer reviewed literature.

    Full Text Available Introduction: Fractal analysis (FA quantifies complex geometric structures by generating a fractal dimension (FD, which can measure the complexity of mucosa. FA is a quantitative tool used to measure the complexity of self-similar or semi-self-similar structures. Aim and Objective: The study was done to perform the FA of oral mucosa with keratotic changes, as it is also made up of self-similar tissues, and thus, its FD can be calculated. Results: In oral leukoplakia, keratinization increases the complexity of mucosa, which denotes fractal geometry. We evaluated and compared pretreated and post-treated oral leukoplakia in 50 patients with clinically proven oral leukoplakia and analyzed the normal oral mucosa and lesional or keratinized mucosa in oral leukoplakia patients through FA using box counting method. Conclusion: FA using the fractal geometry is an efficient, noninvasive prediction tool for early detection of oral leukoplakia and other premalignant conditions in patients.

    To evaluate oral cancer-related screening practices of Oral Health Professionals (OHPs - dentists, dental hygienists, dental therapists, and oral health therapists) practising in Victoria, Australia. A 36-item survey was distributed to 3343 OHPs. Items included socio-demographic and work-related characteristics; self-assessed knowledge of oral cancer; perceived level of confidence in discussing oral health behaviors with patients; oral cancer screening practices; and self-evaluated need for additional training on screening procedures for oral cancer. A total of 380 OHPs responded this survey, achieving an overall response rate of 9.4%. Forty-five were excluded from further analysis. Of these 335 OHP, 72% were dentists; (n = 241); either GDP or Dental Specialists; 13.7% (n = 46) were dental hygienists; 12.2% (n = 41) were oral health therapists, and the remaining 2.1% (n = 7) were dental therapists. While the majority (95.2%) agreed that oral cancer screening should be routinely performed, in actual practice around half (51.4%) screened all their patients. Another 12.8% "Very rarely" conducted screening examinations. The probability of routinely conducting an oral cancer screening was explored utilising Logistic Regression Analysis. Four variables remained statistically significant (p oral cancer screening rose with increasing levels of OHPs' confidence in oral cancer-related knowledge (OR = 1.35; 95% CI: 1.09-1.67) and with higher levels of confidence in discussing oral hygiene practices with patients (OR = 1.25; 95% CI: 1.03-1.52). Results also showed that dental specialists were less likely to perform oral cancer screening examinations compared with other OHPs (OR = 0.18; 95% CI: 0.07-0.52) and the likelihood of performing an oral cancer screening decreased when the "patient complained of a problem" (OR = 0.21; 95% CI: 0.10-0.44). Only half the study sample performed oral cancer screening examinations for all of their patients

    Full Text Available A pesar de su todavía modesta participación en la economía y en el empleo regional, el turismo en Navarra ha mostrado durante los últimos años un significativo dinamismo tal y como, por ejemplo, lo testimonia el incremento del número de visitantes y de las empresas turísticas. Favorecido por una serie de circunstancias de índole variada, este desarrollo turístico se sustenta en una gran diversidad geográfica y cultural patente en los paisajes, el arte, las fiestas, la gastronomía, etc. Pero Navarra es, a su vez, una región que secularmente ha otorgado un gran peso a la tradición y a las creencias religiosas. En este contexto, algunas de las numerosas acciones emprendidas por la administración regional para dinamizar el sector turístico se han encaminado a revalorizar dos importantes legados culturales: el castillo de Javier y el Camino de Santiago. Se aprecia que ambos se hallan estrechamente relacionados con el turismo cultural, el turismo religioso y las peregrinaciones, unos fenómenos que hunden sus raíces en tiempos pasados pero que continúan teniendo en la actualidad una indudable relevancia a escala mundial. La intención primordial del presente trabajo es analizar el turismo de peregrinaciones en Navarra, más concretamente, el que tiene como destino del viaje la cuna de San Francisco Javier. Con dicho afán, se realiza una reflexión conceptual previa y un breve repaso de las fiestas y tradiciones religiosas que forman parte del patrimonio cultural intangible de Navarra, haciendo particular hincapié en las romerías y en el Camino de Santiago. Al hilo de ello, se afronta, a continuación, el estudio de la peregrinación más singular y populosa de Navarra: la Javierada. Su origen, sus principales rasgos, el perfil y las motivaciones de los peregrinos, los caracteres e hitos más importantes del recorrido, las peculiaridades del destino —entendido como lugar sagrado y espacio turístico— constituyen las principales

    Full Text Available This text sets out to illustrate types of basic analysis in researching a question as intrinsically human as perception. In the analysis of a construction, the aspects relative to perception allow us to access interesting information as to how a construction functions and what is implied by its different spaces, information which is in direct relation to more human, living aspects of architecture. These analyses complement formal analyses, as while these allow us to describe a construction in time and space, analyses of perception seek to stress the existing relationship between the human being and the construction, understanding architecture as a physical element to be experienced and which has been constructed to create a favourable atmosphere for certain perceptions. The study first shows the most basic elements in perception analysis and how these support a methodology that attempts to understand a construction in all its aspects (formal, social, symbolic, giving as an example a Neolithic Galician burial mound.Este texto trata de ilustrar los tipos de análisis básicos para investigar una cuestión tan intrínsecamente humana como la percepción. En el análisis de una construcción, los aspectos relativos a la percepción nos permiten acceder a una interesante información de cómo una construcción funciona y qué implican sus distintos espacios, información en directa relación con los aspectos más humanos y vivenciales de la arquitectura. Son unos análisis complementarios a los análisis formales, ya que mientras estos nos permiten describir en el espacio y en el tiempo una construcción, los análisis de percepción tratan de incidir en la relación existente entre el ser humano y la construcción, entendiendo a la arquitectura también como elemento físico a experimentar y que ha sido construido para propiciar ciertas percepciones.

    Oral cancers are attributed to a number of causal agents including tobacco, alcohol, human papillomavirus (HPV), and areca (betel) nut. Although betel nut chewing has been established as an independent cause of oral cancer, the mechanisms of carcinogenesis are poorly understood. An investigation was undertaken to evaluate the influence of betel nut chewing on the oral microbiome and oral premalignant lesions. Study participants were recruited from a dental clinic in Guam. Structured interviews and oral examinations were performed. Oral swabbing and saliva samples were evaluated by 454 pyrosequencing of the V3- V5 region of the 16S rRNA bacterial gene and genotyped for HPV. One hundred twenty-two adults were enrolled including 64 current betel nut chewers, 37 former chewers, and 21 with no history of betel nut use. Oral premalignant lesions, including leukoplakia and submucous fibrosis, were observed in 10 chewers. Within-sample bacterial diversity was significantly lower in long-term (≥10 years) chewers vs. never chewers and in current chewers with oral lesions vs. individuals without lesions. Between-sample bacterial diversity based on Unifrac distances significantly differed by chewing status and oral lesion status. Current chewers had significantly elevated levels of Streptococcus infantis and higher and lower levels of distinct taxa of the Actinomyces and Streptococcus genera. Long-term chewers had reduced levels of Parascardovia and Streptococcus. Chewers with oral lesions had significantly elevated levels of Oribacterium, Actinomyces, and Streptococcus, including Streptococcus anginosus. In multivariate analyses, controlling for smoking, oral HPV, S.anginosus, and S. infantis levels, current betel nut chewing remained the only predictor of oral premalignant lesions. Our study provides evidence that betel nut chewing alters the oral bacterial microbiome including that of chewers who develop oral premalignant lesions. Nonetheless, whether microbial changes

    Full Text Available Neste artigo analisa-se a contribuição dos produtos para a geração de acidentes, apresentando-se estatísticas de acidentes de trabalho, de trânsito e aeronáuticos. Além disso, para melhor ilustrar a relação entre produtos e a ocorrência de acidentes, alguns casos de acidentes ocorridos e divulgados pela mídia são comentados. As estatísticas e os casos comentados demonstram a importância do estudo dos acidentes envolvendo produtos, evidenciando que praticamente todos os acidentes estão relacionados com o uso de produtos industrializados. Então, se analisa histórica e criticamente as principais teorias de acidentes de trabalho, porque são as únicas teorias existentes em relação aos acidentes. Além delas, são analisados os diversos conceitos sobre o erro humano e sua ocorrência, pois estes são apontados como grandes causadores de acidentes. Nesta análise, se observa que os acidentes estão mais relacionados aos perigos ou às características perigosas dos produtos do que às atitudes e ao comportamento do usuário. Faz-se uma revisão dos conceitos associados aos acidentes, tais como perigo, risco, acidente e dano, a partir dos quais apresenta-se um fluxograma contendo os elementos necessários para a manifestação dos acidentes. Ao final, conclui-se que a participação dos produtos na ocorrência de acidentes é evidente e que o comportamento do usuário é dependente das características do produto e da situação na qual ele é utilizado.

    This study, which is motivated by the substantial morbidity of local signs of mucositis and generalized symptoms that result from mucositis induced by therapeutic irradiation, has the following objectives: To investigate if it is possible to prevent irradiation mucositis via oral flora elimination, and, if it is true that flora plays a role in irradiation mucositis, what fraction of the oral flora may be involved; to evaluate oral Gram-negative bacillary carriage; to investigate the possibility to eradicate Gram-negative bacilli from the oral cavity; to evaluate oral yeast carriage; to investigate the possibility to eradicate yeasts stomatitis and the 'selectivity' of elimination of flora. Two methods are described for monitoring alterations of mucositis of the oral cavity and changes in oral flora. Chlorhexidine has been tested as the commonly used prophylaxis. The effect of chlorhexidine 0.1% rinses on oral flora and mucositis has been studied in a prospective placebo controlled double blind randomized programme. The results of the influence of saliva on the antimicrobial activity of chlorhexidine and the results of selective elimination of oral flora in irradiated patients who have head and neck cancer are reported. Salivary inactivation of the topical antimicrobials used for selective elimination of oral flora has been studied and the results are reported. Finally, the objectives that have been achieved (or not) are delineated. The significance of the results of the study are discussed in terms of published information and further lines of research are suggested. (author). 559 refs.; 29 figs.; 20 tabs

    Full Text Available En el año 2005 Martínez-Vargas formuló un sistema de cokrigeage puro heterotópico para estimar una función aleatoria regionalizada (RF Z*(x definida como la combinación lineal de n RF's univariadas Zi(x, cuyos coeficientes 1i(x son indicatrices de un set disyuntivo de categorías i. Aparentemente este modelo se contradice pues asume que las covarianzas cruzadas existen en un mismo punto, a pesar de su carácter puramente heterotópico. Para evadir dicha contradicción se redefinió el set de RF Zi(x como una única RF Z(x,i, siendo los puntos (x,i y (x,j no coincidentes si i y j no son iguales. La heterotopía fue simplemente considerada como una omisión de la RF Z(x,. en los datos y en los puntos a estimar, no impuesta por el modelo; entonces el resultado es simplemente un caso particular del cokrigeage clásico. Con esta notación se reescribió el sistema de cokrigeage clásico como el sistema de krigeage de la RF univariada Z(x,i, asumiendo que esta posee un drift definido como m(x,i,j, donde los miembros fl(x,i,j de m(x,i,j pueden ser linealmente dependientes o independientes. Bajo esta notación el sistema de krigeage se reduce a un sistema univariado, la existencia de más de una variable o la presencia de heterotropía no impone la necesidad de manipulaciones extras para definir el sistema de ecuaciones de krigeage, incrementándose la eficiencia computacional.

    Full Text Available Growing evidence suggests a role for human papillomavirus (HPV in oral cancer; however its involvement is still controversial. This study evaluates the frequency of HPV DNA in a variety of oral lesions in patients from Argentina. A total of 77 oral tissue samples from 66 patients were selected (cases; the clinical-histopathological diagnoses corresponded to: 11 HPV- associated benign lesions, 8 non-HPV associated benign lesions, 33 premalignant lesions and 25 cancers. Sixty exfoliated cell samples from normal oral mucosa were used as controls. HPV detection and typing were performed by polymerase chain reaction (PCR using primers MY09, 11, combined with RFLP or alternatively PCR using primers GP5+, 6+ combined with dot blot hybridization. HPV was detected in 91.0% of HPV- associated benign lesions, 14.3% of non-HPV associated benign lesions, 51.5% of preneoplasias and 60.0% of cancers. No control sample tested HPV positive. In benign HPV- associated lesions, 30.0% of HPV positive samples harbored high-risk types, while in preneoplastic lesions the value rose to 59.9%. In cancer lesions, HPV detection in verrucous carcinoma was 88.9% and in squamous cell carcinoma 43.8%, with high-risk type rates of 75.5% and 85.6%, respectively. The high HPV frequency detected in preneoplastic and neoplastic lesions supports an HPV etiological role in at least a subset of oral cancers.Crecientes evidencias sugieren que el virus Papiloma humano (HPV tiene un rol en el cáncer oral; sin embargo su participación es todavía controvertida.

    Thromboembolic disease (TED) is the leading cause of morbidity and mortality worldwide. The hallmark of oral long-term anticoagulant therapy has been the use of vitamin K antagonists, whose anticoagulant effect is exerted inhibiting vitamin K epoxide reductase. Warfarin and acenocoumarol are the most commonly used. In the last five years several new drugs for long term anticoagulation have been developed, which can inhibit single clotting factors with the purpose of improving drug therapeutic range and, ideally, minimizing bleeding risks. This review addresses the state of the art on the clinical use of inhibitors of activated factor X and thrombin.

    To determine the prevalence and clinicopathologic features of the oral cancer patients. Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected. Sites of the lesion were subdivided into lip, tongue, floor of the mouth, gingiva, alveolar mucosa, palate, buccal/labial mucosa, maxilla and mandible. Oral cancer was subdivided into 7 categories: epithelial tumors, salivary gland tumors, hematologic tumors, bone tumors, mesenchymal tumors, odontogenic tumors, and others. Data were analyzed by descriptive statistics using SPSS software version 17.0. Of the 474,851 accessioned cases, 6,151 cases (1.30%) were diagnosed in the category of oral cancer. The mean age of the patients was 58.37±15.77 years. A total of 4,238 cases (68.90%) were diagnosed in males, whereas 1911 cases (31.07%) were diagnosed in females. The male-to-female ratio was 2.22:1. The sites of predilection for oral cancer were tongue, labial/buccal mucosa, gingiva, palate, and alveolar mucosa, respectively. The three most common oral cancer in the descending order of frequency were squamous cell carcinoma, non-Hodgkin lymphoma and mucoepidermoid carcinoma. Although the prevalence of oral cancer is not high compared to other entities, oral cancer pose significant mortality and morbidity in the patients, especially when discovered late in the course of the disease. This study highlights some anatomical locations where oral cancers are frequently encountered. As a result, clinicians should pay attention to not only teeth, but oral mucosa especially in the high prevalence area as well since early detection of precancerous lesions or cancers in the early stage increase the chance of patient being cured and greatly reduce the mortality and morbidity. This study also shows some differences between pediatric and elderly oral cancer patients as well as between Asian and non-Asian oral cancer patients.

  8. Pathogenesis of oral FIV infection.

    Directory of Open Access Journals (Sweden)

    Craig Miller

    Full Text Available Feline immunodeficiency virus (FIV is the feline analogue of human immunodeficiency virus (HIV and features many hallmarks of HIV infection and pathogenesis, including the development of concurrent oral lesions. While HIV is typically transmitted via parenteral transmucosal contact, recent studies prove that oral transmission can occur, and that saliva from infected individuals contains significant amounts of HIV RNA and DNA. While it is accepted that FIV is primarily transmitted by biting, few studies have evaluated FIV oral infection kinetics and transmission mechanisms over the last 20 years. Modern quantitative analyses applied to natural FIV oral infection could significantly further our understanding of lentiviral oral disease and transmission. We therefore characterized FIV salivary viral kinetics and antibody secretions to more fully document oral viral pathogenesis. Our results demonstrate that: (i saliva of FIV-infected cats contains infectious virus particles, FIV viral RNA at levels equivalent to circulation, and lower but significant amounts of FIV proviral DNA; (ii the ratio of FIV RNA to DNA is significantly higher in saliva than in circulation; (iii FIV viral load in oral lymphoid tissues (tonsil, lymph nodes is significantly higher than mucosal tissues (buccal mucosa, salivary gland, tongue; (iv salivary IgG antibodies increase significantly over time in FIV-infected cats, while salivary IgA levels remain static; and, (v saliva from naïve Specific Pathogen Free cats inhibits FIV growth in vitro. Collectively, these results suggest that oral lymphoid tissues serve as a site for enhanced FIV replication, resulting in accumulation of FIV particles and FIV-infected cells in saliva. Failure to induce a virus-specific oral mucosal antibody response, and/or viral capability to overcome inhibitory components in saliva may perpetuate chronic oral cavity infection. Based upon these findings, we propose a model of oral FIV pathogenesis

    Recent studies suggest that placenta may harbour a unique microbiome that may have origin in maternal oral microbiome. Although the major physiological and hormonal adjustments observed in pregnant women lead to biochemical and microbiological modifications of the oral environment, very few studies evaluated the changes suffered by the oral microbiota throughout pregnancy. So, the aim of our study was to evaluate oral yeast colonization throughout pregnancy and to compare it with non-pregnant women. The oral yeast colonization was assessed in saliva of 30 pregnant and non-pregnant women longitudinally over a 6-months period. Demographic information was collected, a non-invasive intra-oral examination was performed and saliva flow and pH were determined. Pregnant and non-pregnant groups were similar regarding age and level of education. Saliva flow rate did not differ, but saliva pH was lower in pregnant than in non-pregnant women. Oral yeast prevalence was higher in pregnant than in non-pregnant women, either in the first or in the third trimester, but did not attain statistical significance. In individuals colonized with yeast, the total yeast quantification (Log10CFU/mL) increase from the 1st to the 3rd trimester in pregnant women, but not in non-pregnant women. Pregnancy may favour oral yeast growth that may be associated with an acidic oral environment.

    Full Text Available O presente trabalho caracteriza-se como um desdobramento de um projeto de pesquisa da Universidade Estadual do Norte Fluminense (UENF, sobre o estudo de um olhar sobre objetos de aprendizagem como metodologia no ensino da matemática à luz da teoria dos registros de representação semiótica. Nosso trabalho visa verificar a influência da aplicação desta metodologia de ensino na autoestima dos educandos. Essa pesquisa foi desenvolvida dentro do método qualitativo e quantitativo descritivo exploratório, tendo a natureza do objeto e dos objetivos propostos neste estudo. A pesquisa foi realizada no Colégio Maria de Nazaré na Cidade do Rio de Janeiro, onde os alunos responderam o questionário de autoestima de Rosenberg (1989. A pesquisa foi composta por dois grupos um de análise experimental e outro de controle. No Brasil a temática da autoestima é pouco abordada cientificamente. Palavra fácil na psicologização das relações humanas. Por auto-estima entende-se a avaliação que o indivíduo faz de si mesmo. Expressa uma atitude de aprovação ou de repulsa de si e engloba o auto-julgamento em relação à competência e valor Em relação às pequenas diferenças apresentadas nos resultados encontrados nos grupo experimental, há dificuldade em se afirmar categoricamente a questão. Ao avaliar a média do grupo de controle no inicio da pesquisa, encontrava-se em 49,28% de autoestima, no final este mesmo grupo apresenta uma redução para 48,23%de autoestima. Já ao avaliar a média do grupo experimental no inicio da pesquisa este encontrava-se com 47,5% de autoestima, obtendo um aumento para 49,5% após a inserção do objeto de aprendizagem nas aulas.

  12. ORAL ALLERGY SYNDROME

    2011-01-01

    Full Text Available Abstract. Oral allergy syndrome (OAS is defined as a set of clinical manifestations caused by IgE-mediated allergic  reactions  that  occur  at  oral  and  pharyngeal  mucosae  in  the  patients  with  pollen  sensitization  after ingestion of certain fruits, vegetables, nuts and spices. OAS arises from cross-reactivity between specific pollen and food allergens, due to similarity of a configuration and amino acid sequence of allergenic molecules. OAS is considered as class II food allergy, being caused by thermo- and chemolabile allergens, and it is rarely combined with generalized manifestations of food allergy. Prevalence and spectrum of the causal allergens depend on a kind of pollen sensitization. In Moscow region, as well as in Northern Europe, allergic sensitization most commonly occurs to the pollen of leaf trees, whereas OAS is mostly connected with ingestion of fruits from Rosaceae family and nuts. Since last years, a newly developed technique of component-resolved molecular diagnosis (CR diagnostics allows of more precise detection of OAS-causing allergen molecules. These data are of extreme importance for administration of adequate nutritional therapy and prediction of SIT efficiency. (Med. Immunol., 2011, vol. 13, N 1, pp 17-28

    The oral cavity is inhibited by many of the bacterial species. Some of them have a key role in the development of oral disease. Interrelationships between oral microbiome and systemic conditions such as head-and-neck cancer have become increasingly appreciated in recent years. Emerging evidence also suggests a link between periodontal disease and oral cancer, and the explanation being that chronic inflammation could be a major factor in both diseases. Squamous cell carcinoma is that the most frequently occurring malignancy of the oral cavity and adjacent sites, representing over 90% of all cancers. The incidence of oral cancer is increasing, significantly among young people and women. Worldwide there are 350,000-400,000 new cases diagnosed every year. Bacteria, viruses, and fungi are strongly implicated as etiological factors in certain cancers. In this review we will discuss the association between the development of oral cancer in potentially malignant oral lesions with chronic periodontitis, chronic Porphyromonas gingivalis, Fusobacterium nucleatum, candida, other microbes and described mechanisms which may be involved in these carcinoma.

    Los espacios renaturalizados, se consolidan como ambientes de aprendizaje para el ejercicio de la ciudadanía y la convivencia, a partir del desarrollo de metodologías participativas y haciendo uso de tecnologías apropiadas. Para ello se diseñaron e implementaron una serie de sesiones, con el fin de contribuir a la transformación del entorno y de permitir la conectividad ecológica presente en el ecosistema estratégico ubicado allí mismo, además de consolidar experiencias en el desarrollo de capacidades ciudadanas esenciales. Para la institución educativa se construyó, un jardín agroecológico y se sembraron árboles con fines productivos y ornamentales, permitiendo de esa manera la generación de identidad con respecto a los espacios renaturalizados, la estructura ecológica, además de reconocer las relaciones socio-ecológicas que alrededor de estos espacios se desarrollan. Entorno a la intervención, se construyeron conocimientos propios del currículo, además se identificaron las problemáticas ambientales propias de la zona, permitiendo de esa manera la armonización de la relación naturaleza-cultura y la adaptación ecosistémica al cambio climático, que requiere la ciudad de Bogotá.

    Full Text Available El budismo plantea acceder a una visión de la realidad desligada de creencias y supuestos de todo tipo. Para conseguirlo plantea una indagación libre en referencia al enclaustramiento de nuestro pensar y sentir al que nos somete el ego. El ego con sus necesidades y deseos genera un acceso a la realidad relativo a nosotros. Lo que se propone es una liberación de esta lectura para que la realidad pueda aparecer frente a nosotros de manera independiente de las imposiciones del ego, es decir, un acceso a ella ab-soluto (suelto de nosotros. El budismo es, pues, una propuesta de ‘espiritualidad no religiosa’, para la que el mismo término espiritualidad  resultaría inadecuado porque en él subyace la creencia en el ‘espíritu’. Vemos que por todo ello el mensaje budista resulta muy apropiado para las sociedades hoy presentes, bien para aquellas que están transitando de una sociedad agrícola a una industrial, que conlleva a debilitar las convicciones religiosas hasta disolverlas; bien para aquellas que están próximas o han entrado ya en las sociedades llamadas de conocimiento, innovación y cambio continuo cuya condición de movilidad impide  las creencias, porque son fijadoras, lo que arrastra como consecuencia la imposibilidad de tener religión ni espiritualidad.

    Manuel Abad Varela

    1992-01-01

    Full Text Available A la vista de como se han producido la mayoría de los hallazgos analizados y según se desprende de las fuentes escritas, diríamos que en la península ibérica y sobre todo en la parte Occidental se realizaron en la Antigüedad ofrendas monetales a divinidades de las aguas y fundamentalmente, por las referencias que tenemos, a las divinidades de las fuentes termales. Únicamente nos queda la duda de si la fuente de Peña Cutral en Retortillo (Reinosa, Santander es termal o no, pues si no lo fuese sería el único hallazgo dentro de una fuente no termal. Se podría entender, con ciertos reparos en algún caso, que también se hicieron arrojándolas al curso de los ríos, depositándolas en la orilla y lanzándolas a las charcas o pantanos. Por otro lado, las monedas que se han encontrado en las fuentes, en contraposición con las recogidas en los ríos, suelen estar en muy mala conservación, hasta el punto de que muchas se desintegran en las manos al estar muy atacadas por los ácidos. A juzgar por algunos de los hallazgos, se podría creer que las ofrendas más valiosas se procuró depositarlas en lugares seguros o resguardados, como es el caso de la Hermida, de la Fuente de El Sarso, del Balneario de Fortuna y podríamos recordar también el hallazgo del conocido depósito de Oñate. De acuerdo con la cronología de las monedas y según sus resultados estadísticos, la costumbre o rito de depositar o arrojar «stips» a las aguas, principalmente termales, se practicó en la península Ibérica más intensamente entre los siglos i a. C. al ii d. C. Este período coincide con el momento que más estuvo en boga el uso de las aguas termales, a juzgar por lo que se trató el tema en las fuentes escritas.

    Full Text Available Joseph Beuys, nacido en Cléveris (Renania del Norte-Westfalia en 1921 y faliecido en Dusseldorf en 1986, posee una obra madura casi desde un primer momento. Superficialmente podríamos verla como el canto a sí mismo de un gran narcisista, donde sus experiencias y su persona son los grandes protagonistas. En una lectura más profunda, estos hechos personales no son más que el medio para ir más allá del yo y dar lugar a una creación plástica de trascendencia social. Tras la 2- Guerra Mundial, en la que lucha como piloto de la Luftwaffe, estudia en la Academia de Bellas Artes de Dusseldorf. Será a partir de los años 60 cuando encontremos al auténtico Beuys, escultor objetual e instalador, el creador de la plástica social, y desde sus contactos con Fluxus en 1962, el Beuys accionista. En los 70, se nos presenta el artista más claramente politizado. La educación, la incidencia social del arte, el arte como «tercera vía o vía alternativa» entre socialismo y capitalismo, la ecología serán sus materiales de trabajo.

    Madinier, I; Berry, N; Chichmanian, R M

    2000-06-01

    Different side effects of drugs have been described in the oral cavity, including oral ulcerations. Direct contact between drugs and oral mucosa may induce chemical burn or local hypersensitivity. Less frequently, these drug-induced oral ulcerations are part of a complex reaction with cutaneous or systemic manifestations. Sometimes, one or more oral ulcerations appear as the main side-effect of a drug, or exceptionally as solitary lesions. Solitary oral ulcerations usually appear after few weeks of treatment. In most of cases, these lesions resist to conventional treatments, with a rapid healing following the suppression of the responsible drug. This diagnosis is usually difficult, particularly with patients receiving multiple drug therapy. Besides, special attention must be paid to new drugs. Oral ulcerations following symptoms of burning mouth, metallic taste, dysgueusia or agueusia are strongly suggestive of a pharmacological origin. Most of the molecules able to induce solitary oral ulcerations are commonly prescribed in a) rheumatology: NSAI (diclofenac, flurbiprofen, indomethacin, naproxen), long-term rheumatoid arthritis therapy (azathioprine, methotrexate, penicillamine, gold compounds, tiopronin); b) cardiology: angiotensin-converting-enzyme inhibitors (captopril, enalapril), angiotensin 2-receptor antagonist (losartan), anti-angorous (nicorandil), c) psychiatry: antidepressants (fluoxetine, lithium), d) AIDS therapy (foscarnet, zalcitabine).

    2014-01-01

    Introducción: Las malformaciones del tubo neural (MTN) representan la segunda causa más frecuente de anomalías congénitas, luego de las cardiopatías. En este grupo se destaca el mielomeningocele (MMC) por su mayor incidencia, y por ser la más incapacitante y la más compleja entre todas las demás malformaciones del sistema nervioso c`entral (SNC). En Bolivia, como en muchos países de Sudamérica, los bajos niveles socio-culturales y la debilidad en el sistema sanitario, hacen que su incidencia y su morbilidad, sean mayores que en las naciones más desarrolladas. Material y Métodos: Se realizó un estudio retrospectivo y descriptivo de 70 casos de MMC, atendidos por un equipo multidisciplinario en el Hospital Universitario Japonés (HUJ) de Santa Cruz de la Sierra, entre 2008-2011. De ellos, 60 fueron intervenidos quirúrgicamente. Resultados: Se realizaron controles prenatales sólo en 27 mujeres (38.6%), diagnosticándose una disrafia espinal en apenas dos casos (7.4%). La edad de ingreso del MMC en su mayoría fue después de las 24 horas (65.6%), predominando su localización en la región lumbosacra (64.3%). De ellos, 67.2% eran abiertos, presentando un 32.9% un daño neurológico motor parcial mientras que 47.1% tenían paraplejia por debajo de la lesión. De los 70 casos, tres (4.3%) no fueron intervenidos, por presentar defectos congénitos severos o estado general grave. Las principales complicaciones posoperatorias inmediatas fueron: dehiscencia de sutura y/o infección de la herida (16.6%), fístula de líquido cefalorraquídeo (LCR) (10%) e infección del SNC (11.7%). La mortalidad general y postoperatoria fue de 7.1% y 3.3%, respectivamente. Al mes de vida presentaban hidrocefalia un 80% de los pacientes operados, colocándose una derivación ventriculoperitoneal (DVP) de presión media. De 9 pacientes que tuvieron un acompanamiento de dos o más años, seis presentaron una médula anclada, que fueron intervenidas quirúrgicamente. Conclusi

  3. Teresa Wilms Montt: la visceralidad como activismo

    2017-07-01

    Full Text Available Es usual señalar que el debate sobre las emociones solo pasó a formar parte del feminismo en los últimos años. Sin embargo, es notoria la referencia en la literatura feminista de la primera ola al espacio de lo íntimo en términos de una colisión de emociones profundamente política que puede ser definida en términos de “visceralidad”. El presente trabajo se enmarca en un proyecto que tiene como objetivo final señalar el modo en que la transmisión de los afectos formó parte fundamental de la constitución del feminismo en América Latina. Este artículo se ocupa analizar la producción de la escritora chilena Teresa Wilms Montt, muy particularmente su primera obra, “Inquietudes sentimentales” (1917. No se trata meramente de argumentar la presencia de la dimensión emocional, sino de indagar en la especificidad de ese momento de su escritura donde la categoría de ‘intimidad” se torna central a la hora de establecer principios feministas. Son las características de su recorrido -donde entran en colisión las emociones más diversas - y el vínculo que establece con las luchas políticas del feminismo de corte anarquista las que abren la posibilidad de entender esta etapa, dando cuenta de la constitución de una geografía afectiva para el activismo latinoamericano. Una geografía marcada, centralmente por el desafío a “estructuras del sentir” patriarcales a través de intervenciones que sacan a la luz el papel politico de la visceralidad en tanto acción.

  4. The Oral Paradigm and Snapchat

    Directory of Open Access Journals (Sweden)

    Oren Soffer

    2016-09-01

    Full Text Available In this short essay, I argue that the ephemeral nature of emerging instant-messaging applications, such as Snapchat, applies an oral paradigm. While online discourse of computer-mediated communication shares many qualities with oral communication, the case of ephemeral applications is unique, as the oral features are already integrated in the application technology design and as orality is often implemented on highly visual products. Snapchat applies technology that fades visual contents as if they were spoken words fading in the air after utterance. Moreover, Snapchat’s promise to delete all messages from its database after they are viewed echoes a key characteristic of primary oral culture: that is, the inability (and in our case, the obligation not to store knowledge. In this, Snapchat demonstrates counter-logic to the contemporary grammar of new media, which is based on information aggregation.

    Vitamin K antagonists were the only choice for chronic oral anticoagulation for more than half a century. Over the past few years, direct oral anticoagulants have emerged, including one direct thrombin inhibitor (dabigatran etexilate) and three factor Xa inhibitors (apixaban, edoxaban and rivaroxaban). In randomised controlled trials comparing direct oral anticoagulants with traditional vitamin K antagonists, the direct oral anticoagulants all showed a favourable benefit-risk balance in their safety and efficacy profile, in prevention of thromboembolic events in patients with atrial fibrillation and in the prevention and treatment of venous thromboembolism and acute coronary syndrome. In 2008, dabigatran was the first direct oral anticoagulant approved by the European Medicine Agency. Subsequently, rivaroxaban, apixaban and edoxaban were also authorised. This article reviews the evidence related to the use of these drugs. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    Candidiasis, an often encountered oral disease, has been increasing in frequency. Most commonly caused by the overgrowth of Candida albicans, oral candidiasis can be divided into several categories including acute and chronic forms, and angular cheilitis. Risk factors for the development of oral candidiasis include immunosuppression, wearing of dentures, pharmacotherapeutics, smoking, infancy and old age, endocrine dysfunction, and decreased salivation. Oral candidiasis may be asymptomatic. More frequently, however, it is physically uncomfortable, and the patient may complain of burning mouth, dysgeusia, dysphagia, anorexia, and weight loss, leading to nutritional deficiency and impaired quality of life. A plethora of antifungal treatments are available. The overall prognosis of oral candidiasis is good, and rarely is the condition life threatening with invasive or recalcitrant disease.

    Forensic odontology is the subdiscipline of dentistry which analyses dental evidence in the interest of justice. Oral pathology is the subdiscipline of dentistry that deals with the pathology affecting the oral and maxillofacial regions. This subdiscipline is utilized for identification through oral and maxillofacial pathologies with associated syndromes, enamel rod patterns, sex determination using exfoliative cytology, identification from occlusal morphology of teeth, and deoxyribonucleic acid profiling from teeth. This subdiscipline is also utilized for age estimation studies which include Gustafson's method, incremental lines of Retzius, perikymata, natal line formation in teeth, neonatal line, racemization of collagen in dentin, cemental incremental lines, thickness of the cementum, and translucency of dentin. Even though the expertise of an oral pathologist is not taken in forensic investigations, this paper aims to discuss the role of oral pathology in forensic investigation.

    2016-01-01

    Organisms residing in the oral cavity (oral microbiota) contribute to health and disease, and influence diseases like gingivitis, periodontitis, and oral candidiasis (the most common oral complication of HIV-infection). These organisms are also associated with cancer and other systemic diseases including upper respiratory infections. There is limited knowledge regarding how oral microbes interact together and influence the host immune system. Characterizing the oral microbial community (oral microbiota) in health and disease represents a critical step in gaining insight into various members of this community. While most of the studies characterizing oral microbiota have focused on bacterial community, there are few encouraging studies characterizing the oral mycobiome (the fungal component of the oral microbiota). Our group recently characterized the oral mycobiome in health and disease focusing on HIV. In this chapter we will describe the methods used by our group for characterization of the oral mycobiome.

    Full Text Available Introdução: as lesões pigmentadas podem ser encontradas na cavidade oral, essas pigmentações são provenientes de diversos fatores, tais como, locais, sistêmicos, fisiológicos ou patológicos. A cor, localização, distribuição e duração são características essenciais para o diagnóstico destas lesões, não devendo- se negligenciar a história médica, odontológica e familiar, bem como o consumo de drogas. Apesar de algumas lesões apresentarem características bastante específicas que as confere um diagnóstico apenas através do exame clínico, é importante que o profissional lance mão de métodos adicionais, como biópsias e exames laboratoriais, afim de alcançar um diagnóstico confiável e consequentemente, executar o tratamento adequado. Objetivos: essa revisão de literatura tem como objetivo discorrer sobre as principais lesões orais enegrecidas da cavidade oral, enfatizando o diagnóstico diferencial para cada uma delas, já que tal abordagem implicará diretamente na conduta profissional e no estabelecimento do tratamento adequado para cada paciente. Métodos: para isso foi realizada uma revisão de literatura através da busca de artigos no PubMED/Medline, Lilacs e Scielo. Resultados: a literatura estudada destacou que as lesões pigmentadas orais e maxilofaciais podem clinicamente simular o melanoma, uma lesão maligna. Conclusões: devemos ter especial atenção durante o exame clínico deste tipo de ocorrência, saber questionar o paciente para obter informações importantes a respeito da lesão, ter conhecimento dos diferentes tipos de lesões pigmentadas que acometem a cavidade oral e face, assim como ter em mente a necessidade do exame histopatológico para se obter o diagnóstico definitivo de lesões pigmentadas suspeitas.

    The purpose of this multicentre study was to determine the incidence of oral candidiasis in patients treated with topical steroids for oral lichen planus (OLP) and to determine whether the application of a concurrent antifungal therapy prevented the development of an oral candidiasis in these patients. Records of 315 patients with OLP seen at four Oral Medicine practices treated for at least 2 weeks with steroids with and without the use of an antifungal regimen were retrospectively reviewed. The overall incidence of oral fungal infection in those treated with steroid therapy for OLP was 13.6%. There was no statistically significant difference in the rate of oral candidiasis development in those treated with an antifungal regimen vs those not treated prophylactically (14.3% vs 12.6%) (P = 0.68). Despite the use of various regimens, none of the preventive antifungal strategies used in this study resulted in a significant difference in the rate of development of an oral candidiasis in patients with OLP treated with steroids. © 2015 John Wiley & Sons A/S.

    Background To determine the prevalence and clinicopathologic features of the oral cancer patients. Material and Methods Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected. Sites of the lesion were subdivided into lip, tongue, floor of the mouth, gingiva, alveolar mucosa, palate, buccal/labial mucosa, maxilla and mandible. Oral cancer was subdivided into 7 categories: epithelial tumors, salivary gland tumors, hematologic tumors, bone tumors, mesenchymal tumors, odontogenic tumors, and others. Data were analyzed by descriptive statistics using SPSS software version 17.0. Results Of the 474,851 accessioned cases, 6,151 cases (1.30%) were diagnosed in the category of oral cancer. The mean age of the patients was 58.37±15.77 years. A total of 4,238 cases (68.90%) were diagnosed in males, whereas 1911 cases (31.07%) were diagnosed in females. The male-to-female ratio was 2.22:1. The sites of predilection for oral cancer were tongue, labial/buccal mucosa, gingiva, palate, and alveolar mucosa, respectively. The three most common oral cancer in the descending order of frequency were squamous cell carcinoma, non-Hodgkin lymphoma and mucoepidermoid carcinoma. Conclusions Although the prevalence of oral cancer is not high compared to other entities, oral cancer pose significant mortality and morbidity in the patients, especially when discovered late in the course of the disease. This study highlights some anatomical locations where oral cancers are frequently encountered. As a result, clinicians should pay attention to not only teeth, but oral mucosa especially in the high prevalence area as well since early detection of precancerous lesions or cancers in the early stage increase the chance of patient being cured and greatly reduce the mortality and morbidity. This study also shows some differences between pediatric and elderly oral cancer patients as well as

    1988-07-01

    Full Text Available This study presents a synthetic and personal view of the consequences arising from the notion of law as justice. For Kelsen, in this "Theory of pure law", human conduct produce facts, justly or injust1y, that become characterized as legal norms. Human behavior is determined by acts of reason, that are defined by a representative (a judge, and then are used as valid norms of justice. The conception of law is, therefore, represented by an ideal object, rational and only apprehensible through abstract processes, following the views of Kelsenians. Without any intent to criticize the "great master of Vienna", a search of the text demonstrates that a neutral ideology, concerning the comprehension and application of law, does not and can not exists law can not depart from empirical reality when following its purpose of promoting the liberty and development of society.O presente texto tem por finalidade apresentar uma visão sintética e pessoal das conseqüências decorrentes da noção do direito como juízo. Para KELSEN, em sua "Teoria pura do direito", a conduta humana produz fatos jurídicos ou injurídicos, conforme assim os caracterizam as normas jurídicas. A conduta humana é determinada por uma razão de agir, que é definida pela representação juízo que o homem tem da norma jurídica 'vigente. A concepção do direito é, pois, representada por um objeto ideal, racional e somente apreensível através de um processo de abstração, segundo a visão Kelseniana. Sem a mínima pretensão de formular críticas ao grande Mestre de Viena, procura o texto demonstrar que a neutralidade ideológica, para a compreensão e aplicação do direito, não existe e nem pode existir, eis que o direito não pode se afastar da realidade empírica, a fim de que possa alcançar sua finalidade de promover a libertação e a evolução da sociedade.

Ao ser diagnosticado na cavidade bucal, deve-se monitorar o paciente a fim de avaliar possíveis complicações sistêmicas da doença. Diante disso, o objetivo do presente estudo é relatar um caso de amiloidose oral em uma paciente do gênero feminino de 72 anos de idade. Baseado nos sinais clínicos observados, a hipótese diagnóstica foi de fibroma traumático. Após realização de biópsia e exame histopatológico, o diagnóstico foi de amiloidose oral, o que foi confirmado com a coloração do espécime com o reagente vermelho congo. Depósitos de amilóide foram encontrados no tecido conjuntivo, na avaliação através da luz polarizada, que apresentou birrefringência. Tal achado foi preocupante, já que a amiloidose geralmente acomete diversos tecidos levando a comprometimentos sistêmicos. Por essa razão a paciente foi encaminhada a procurar atendimento médico. No entanto, houve abandono do tratamento e a mesma veio a óbito 6 meses após o diagnóstico da doença. Lesões orais aparentemente simples podem revelar doenças raras e de difícil tratamento.

    Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide. It accounts for 2.5% of all new cancer cases and 1.9% of all cancer deaths annually. More than 90% of oral cancers (occurring in the mouth, lip, and tongue) are oral squamous cell carcinoma. The incidence rate of oral cancer varies widely throughout the world, with an evident prevalence in South Asian countries. This high incidence occurs in correlation with oral cancer-associated behaviors such as alcohol, tobacco use. Researchers have reported that these behaviors lead to genetic variations in tumor suppressor genes (APC, p53), proto-oncogenes (Myc), oncogene (Ras) and genes controlling normal cellular processes (EIF3E, GSTM1). Processes such as segregation of chromosomes, genomic copy number, loss of heterozygosity, telomere stabilities, regulations of cell-cycle checkpoints, DNA damage repairs and defects in notch signaling pathways are involved in causing oral cancer. In order to develop preventive and therapeutic options, it is necessary to comprehend the basic molecular mechanisms forcing oral tumorigenesis. This review examines, in detail, the mechanisms of genetic alteration which are considered to be responsible for the initiation of oral cancer. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The diagnosis between different diseases may be impaired by clinical and histopathologic similarities, as observed in the oral lichen planus (OLP) and oral lichenoid lesion (OLL). Inspite of similar clinicopathological features; etiology, diagnosis and prognosis differ which mandates separation of OLL from OLP. Hence, it is essential for the oral physician and oral pathologist to be familiarized with the individual variations among clinicopathological features of OLP and OLL as well as to obtain a thorough history and perform a complete mucocutaneous examination in addition to specific diagnostic testing. The difficulties faced to establish the diagnosis between these two pathologies are widely investigated in the literature with a lack of definite conclusion. This review is an attempt to throw some light on these clinicopathologic entities with the aim to resolve the diagnostic dilemma. PMID:26980966

  18. Recurrent oral angioleiomyoma

    Full Text Available Angioleiomyomas are vascular variant of leiomyomas which are benign tumors of smooth muscle. They are exceedingly rare in the oral cavity. Malignant transformation of these tumors has also been reported occasionally which warrants knowledge of this soft tissue tumor. A 57 year old male patient reported with a 15 day history of an asymptomatic growth that had started insidiously in his lower left back tooth region. Clinical examination revealed a solitary, oval, sessile growth in the mandibular left retro molar region. Excisional biopsy was suggestive of Angioleiomyoma. A recurrence of the same was noted two months later which was also histopathologically reported as Angioleiomyoma. The same was confirmed using special stains. This case reports an unusual presentation of Angioleiomyoma with regards to both recurrence as well as rapid growth. It is important to be well aware of this uncommon entity as these tumors often can mimic or transform into malignancy. Precise clinicopathological examinations are therefore invaluable in establishing an accurate diagnosis and delivering suitable treatment.

    Abstract Oral contraceptives (OCs) following induced abortion offer a reliable method to avoid repeated abortion. However, limited data exist supporting the effective use of OCs postabortion. We conducted this systematic review and meta-analysis in the present study reported immediate administration of OCs or combined OCs postabortion may reduce vaginal bleeding time and amount, shorten the menstruation recovery period, increase endometrial thickness 2 to 3 weeks after abortion, and reduce the risk of complications and unintended pregnancies. A total of 8 major authorized Chinese and English databases were screened from January 1960 to November 2014. Randomized controlled trials in which patients had undergone medical or surgical abortions were included. Chinese studies that met the inclusion criteria were divided into 3 groups: administration of OC postmedical abortion (group I; n = 1712), administration of OC postsurgical abortion (group II; n = 8788), and administration of OC in combination with traditional Chinese medicine postsurgical abortion (group III; n = 19,707). In total, 119 of 6160 publications were included in this analysis. Significant difference was observed in group I for vaginal bleeding time (P = 0.0001), the amount of vaginal bleeding (P = 0.03), and menstruation recovery period (P abortion (P abortion, and reduce the risk of complications and unintended pregnancies.

  20. Oral sensations and secretions.

    Running, Cordelia A

    2018-04-10

    Sensations experienced in the mouth influence food choices, both immediately and in the long term. Such sensations are themselves influenced by experience with flavors, the chemical environment of the mouth, genetics of receptors for flavors, and individual behavior in the chewing of food. Gustation, the sense of taste, yields information about nutrients, influences palatability, and feeds into the human body's preparation to receive those nutrients. Olfaction, the sense of smell, contributes enormously to defining and identifying food flavors (and is experienced even after placing food inside the mouth). Another vital component of food flavor is texture, which contributes to palatability, especially if a food's texture violates a person's expectations. Next, chemesthesis is the sense of chemically induced irritancy and temperature, for example spiciness and stinging. All of these sensations are potentially modified by saliva, the chemical and physical media of the mouth. As a person experiences the culmination of these oral sensations, modified through an individual's own unique saliva, the flavors in turn influence both what and how a person eats.

    Full Text Available Mycetoma is a pathological process in which eumycotic (fungal or actinomycotic causative agents from exogenous source produce grains. It is a localized chronic and deforming infectious disease of subcutaneous tissue, skin and bones. We report the first case of eumycetoma of the oral cavity in world literature. CASE REPORT: A 43-year-old male patient, complaining of swelling and fistula in the hard palate. On examination, swelling of the anterior and middle hard palate, with fistula draining a dark liquid was observed. The panoramic radiograph showed extensive radiolucent area involving the region of teeth 21-26 and the computerized tomography showed communication with the nasal cavity, suggesting the diagnosis of periapical cyst. Surgery was performed to remove the lesion. Histopathological examination revealed purulent material with characteristic grain. Gram staining for bacteria was negative and Grocott-Gomori staining for the detection of fungi was positive, concluding the diagnosis of eumycetoma. The patient was treated with ketoconazole for nine months, and was considered cured at the end of treatment. CONCLUSION: Histopathological examination, using histochemical staining, and direct microscopic grains examination can provide the distinction between eumycetoma and actinomycetoma accurately.

    Hydroxyurea is an antimetabolite that is widely used in the treatment of many benign and malignant conditions. This drug is usually well tolerated but has a number of side effects that vary in incidence. In cases of clinically significant adverse events, hydroxyurea is usually discontinued either temporarily or permanently, depending on treatment need versus harm caused by side effects. Here, we report a case of oral ulceration associated with hydroxyurea treatment in a patient who had chronic myelogenous leukemia. The patient rapidly developed an oral ulcer 12 days after administration of the drug. Hydroxyurea was discontinued, and the oral lesion appreciably decreased in size and severity. Physicians and dentists should be aware of the association between hydroxyurea and oral lesions. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Diabetes mellitus is one of the most common non-communicable chronic diseases, which is the combined action of genetic factors, environmental factors and lifestyle. Specific conditions occur in the oral cavity in the course of diabetes that cause changes in all oral tissues with different symptoms and signs. Increased salivary glucose level is followed by increased accumulation of dental plaque and decreased resistance to noxious agents. The most common oral manifestations in diabetic patients include higher prevalence of periodontal desease, burning mouth syndrome, disruption in salivary flow, opportunistic infections, higher prevalence of denture stomatitis, oral lichen planus, fissured tongue, angular cheilitis etc. Dental interventions in patients with well-controlled diabetes are not different from those applied to nondiabetic patients. Regular monitoring of these patients is required because of the complications that can occur.

  14. Oral contraceptives and neuroactive steroids.

    Science.gov (United States)

    Rapkin, Andrea J; Biggio, Giovanni; Concas, Alessandra

    2006-08-01

    A deregulation in the peripheral and brain concentrations of neuroactive steroids has been found in certain pathological conditions characterized by emotional or affective disturbances, including major depression and anxiety disorders. In this article we summarize data pertaining to the modulatory effects of oral contraceptive treatment on neuroactive steroids in women and rats. Given that the neuroactive steroids concentrations are reduced by oral contraceptives, together with the evidence that a subset of women taking oral contraceptives experience negative mood symptoms, we propose the use of this pharmacological treatment as a putative model to study the role of neuroactive steroids in the etiopathology of mood disorders. Moreover, since neuroactive steroids are potent modulators of GABA(A) receptor function and plasticity, the treatment with oral contraceptives might also represent a useful experimental model to further investigate the physiological role of these steroids in the modulation of GABAergic transmission.

    Directory of Open Access Journals (Sweden)

    Domenico Losurdo

    2011-04-01

    Full Text Available Por muito tempo o “marxismo ocidental” celebrou a sua superioridade em relação ao marxismo dos países que se remetiam ao socialismo e que estavam todos situados no Oriente. Em decorrência dessa atitude arrogante, o marxismo ocidental nunca se empenhou seriamente em repensar a teoria de Marx à luz de um balanço histórico concreto: qual era o papel do Estado e da nação nesses países e no “campo socialista”? Como promover a democracia e os direitos humanos e como estimular o desenvolvimento das forças produtivas e o bem-estar das massas numa situação caracterizada pelo bloqueio capitalista? Ao invés de pôr-se essas questões difíceis, o marxismo ocidental preferiu abandonar-se à cômoda atitude autoconsolatória de quem cultiva em particular as suas utopias e rejeita, como uma contaminação, o contato com a realidade e a reflexão sobre a realidade. Disso derivou uma progressiva capitulação à ideologia dominante. Por fim, a autocelebração do marxismo ocidental desembocou na sua autodissolução. Palavras-chave: Marxismo ocidental. Campo socialista. Falta de balanço histórico. Autodissolução. For a long time the “occidental Marxism” celebrated its superiority over the Marxism established in countries located in the Orient, to where the socialism was related. Due to this arrogante attitude, the occidental Marxism has never endeavored to rethink Marx’s theory upon a concrete historical summary: what was the role of the State and Nation in these countries and in the “socialist field”? How to promote the democracy and the human rights and how to estimulate the development of the productive forces and people’s welfare within a situation featured by the capitalist interdiction? Instead of opposing to those difficult questions, the occidental Marxism preferred to remain at a comfortable and self-consolating attitude, cultivating their particular utopias and rejecting, as a contamination, the contact to and

  3. Peran 'Oral Splint' pada Bruxisme

    Directory of Open Access Journals (Sweden)

    Antonia Tanzil

    2013-07-01

    Full Text Available Oral splints have been frequently used in the treatment of bruxism to protect teeth and periodontium from damage, but the mechanism of action and efficacy of oral splints remain controversial. It has been suggested that they can be used to treat bruxism, based on the assumption that the device can eliminate or remove occlusal interference. Currently there are no reliable data to support the assumption of occlusion as an etiologic factor for bruxism, because several other factors have a role in bruxism, such as psychiatric, neurological and systemic disorders. In this paper, the mechanism of action and efficacy of oral splints in bruxism are discussed. Conclusions: although oral splint may be beneficial in protecting the dentition, the efficacy of this device in reducing bruxism is still not confirmed. There are several aspects that would support the broad usage of oral splints in the treatment of bruxism, but there are also limitations associated with each of these aspects. In conclusion, oral splints can be considered as useful adjuncts in the management of sleep bruxism but not as a definitive treatment.DOI: 10.14693/jdi.v15i1.82

    Olga Matilde Restrepo Forero

    2009-10-01

    Full Text Available El fenómeno de la difusión del Darwinismo ha sido ampliamente estudiado. No solo existe una “Industria de Darwin” que se ha ocupado de investigar cómo se produjo la obra de Darwin, sino que también existe una “Industria de la Difusión del Darwinismo”, que investiga los procesos de recepción del Darwinismo en diversas partes del mundo. En el artículo se cuestiona la separación entre los estudios que examinan la producción del Origen de las especies y los que estudian su posterior difusión, considerados como procesos completamente independientes. Con base en unos pocos ejemplos, se muestra cómo Darwin fue produciendo y modificando su obra a partir de las contribuciones que fue recogiendo en diferentes partes del mundo y a partir de las respuestas que fue recibiendo a medida que su obra era comentada y discutida. Fianlmente se examina cómo al estudiar la mundialización del darwinismo surge el problema de cómo definir el fenómeno bajo estudio, si con una perspectiva normativa, que imponga un orden en la proliferación de sentidos que surge como consecuencia de la expansión, o con una perspectiva no-esencialista que más bien sitúe al darwinismo en relación con sus diferentes usos y apropiaciones locales.

    Full Text Available Los neurilemomas son tumores neurogénicos benignos, con origen en la vaina neural. De los neurilemomas extracraneales, aproximadamente un 25 a un 45% ocurren en cabeza y cuello. La edad de afectación predominante es entre la tercera y la cuarta décadas de vida. El neurilemoma es un tumor claramente circunscrito y, generalmente, de pequeño tamaño. Clínicamente aparece como una masa de crecimiento lento y gradual. El examen microscópico es necesario para el diagnóstico. El tratamiento de elección es la escisión quirúrgica completa tumoral y después de ésta es muy rara su recurrencia. El propósito de este artículo es presentar un estudio retrospectivo, de nueve casos, de neurilemomas de cavidad oral y cuello, tratados en nuestro servicio de Cirugía Oral y Maxilofacial, entre 1997 y 2001. Hemos valorado una serie de parámetros epidemiológicos (edad, sexo, localización, tamaño, clínica, estudios previos a la cirugía, tiempo trascurrido entre aparición de síntomas y primera consulta, nervio de origen, patrón histológico predominante (Antoni A, Antoni B, y evolución postquirúrgica. Se ha realizado una revisión de la literatura.Neurilemomas are benign neurogenic tumours, that derive from the neural sheath.

Entretanto, las condiciones clínicas que más se asocian con ésta son la hipertensión arterial, la insuficiencia cardíaca, la enfermedad valvular cardíaca y la diabetes mellitus. Como complicaciones está la falla cardiaca, pero tal vez una de las peores son los eventos cardioembólicos, que ocurren aproximadamente en 4,5% de los pacientes no anticoagulados. El tratamiento antitrombótico con antagonistas de la vitamina K fue, durante más de cincuenta años, la única alternativa disponible, a pesar de sus múltiples limitaciones, las mismas que llevaron al desarrollo de nuevos fármacos anticoagulantes que disminuyen muchos de los problemas de los antagonistas de la vitamina K. Pueden agruparse en dos clases: inhibidores orales directos de la trombina e inhibidores orales del factor X activado.

    Oral contraceptive (OC) options for adolescents are provides. Clarification for those desiring a birth control method is necessary and the benefits of decreased acne and dysmenorrhea with low dose OCs should be stressed along with the importance of compliance. A community effort is suggested to communicate the sexual and contraceptive alternatives, including abstinence and outercourse (sexual stimulation to orgasm without intercourse). Attention is given to concerns associated with teenage sexual activity, prevention of adolescent pregnancy, contraceptive options for the adolescent patient, adolescent attitudes toward birth control OCs, management of the adolescent OC user, manipulation of steroid components of OCs to respond to adolescent concerns, and other hormonal contraceptive options such as minipills or abstinence. The text is supplemented with tables: the % of US women by single years of age for 1971, 1976, 1979, and 1982; comparative pregnancy and abortion rates for the US and 5 other countries; federal cost for teen childbearing; adolescent nonhormonal contraceptive methods (advantages, disadvantages, and retail cost); checklist to identify those at risk for noncompliance with OCs; hormonal side effects of OCs; risks from OCs to adolescents; and benefits of OCs. Concern about adolescent pregnancy dates back to Aristotle. A modern profile shows girls form single-parent families are sexually active at an earlier age, adolescent mothers produce offspring who repeat the cycle, victims of sexual abuse are more likely to be sexually active, and teenagers in foster care are 4 times more likely to be sexually active and 8 times more likely to become pregnant. Prevention involves a multifaceted approach. OCs are the most appropriate contraceptive choice for adolescents. Frequency of intercourse is closely associated with OC use after approximately 15 months of unprotected sexual activity. At risk for noncompliance variables are scales of personality development

    Individual bacteria and shifts in the composition of the microbiome have been associated with human diseases including cancer. To investigate changes in the microbiome associated with oral cancers, we profiled cancers and anatomically matched contralateral normal tissue from the same patient by sequencing 16S rDNA hypervariable region amplicons. In cancer samples from both a discovery and a subsequent confirmation cohort, abundance of Firmicutes (especially Streptococcus) and Actinobacteria (especially Rothia) was significantly decreased relative to contralateral normal samples from the same patient. Significant decreases in abundance of these phyla were observed for pre-cancers, but not when comparing samples from contralateral sites (tongue and floor of mouth) from healthy individuals. Weighted UniFrac principal coordinates analysis based on 12 taxa separated most cancers from other samples with greatest separation of node positive cases. These studies begin to develop a framework for exploiting the oral microbiome for monitoring oral cancer development, progression and recurrence. PMID:24887397

The article first addresses the issue of reliability and rigor of oral history as compared to written sources and then concentrates on the creation of Mercosur as an example of the validity of oral history under the three circumstances identified. The conclusion proposes a revival of a more historical approach to political studies.Este artículo argumenta en favor del uso de la historia oral como método de estudio de las relaciones internacionales y de las ciencias políticas.

    RESUMO

    A educação formal para o trabalho, em nível superior, começa a enfrentar uma concorrência inusitada: as universidades corporativas, surgidas das experiências de programas de treinamento e desenvolvimento profissionais corporativos e da constatação de que a universidade não prepara adequadamente para o trabalho. O conceito de universidade corporativa surgiu nos EUA, em 1995, quando a General Eletric criou a Cotronville. Mas foi só a partir da década de 80 que se assistiu a um aumento considerável destes novos espaços de formação. Outro componente que contribuiu para o rápido crescimento das universidades corporativas é a necessidade de contínua aprendizagem, como conseqüência das vertiginosas mudanças no mundo do trabalho, em razão dos avanços tecnológicos permanentes e do processo de globalização da economia. As universidades corporativas surgem como solução para o alinhamento das iniciativas de treinamento com a estratégia da organização e de criação de vantagem competitiva, por meio de aprendizado permanente.

    Pigmented oral lesions compose a large number of pathological entities, including exogenous pigmentat oral tattoos, such as amalgam and graphite tattoos. We report a rare case of a graphite tattoo on the palate of a 62-year-old patient with a history of pencil injury, compare it with amalgam tattoos, and determine the prevalence of oral tattoos in our Oral Pathology Service. We also compare the clinical and histological findings of grafite and amalgam tattoos. Oral tattoos affect women more frequently in the region of the alveolar ridge. Graphite tattoos occur in younger patients when compared with the amalgam type. Histologically, amalgam lesions represent impregnation of the reticular fibers of vessels and nerves with silver, whereas in cases of graphite tattoos, this impregnation is not observed, but it is common to observe a granulomatous inflammatory response, less evident in cases of amalgam tattoos. Both types of lesions require no treatment, but in some cases a biopsy may be done to rule out melanocytic lesions.

It is very common in Southeast Asia but has started to spread to Europe and North America. OSF can lead to squamous cell carcinoma, a risk that is further increased by concomitant tobacco consumption. OSF is a diagnosis based on clinical symptoms and confirmation by histopathology. Hypovascularity leading to blanching of the oral mucosa, staining of teeth and gingiva, and trismus are major symptoms. Major constituents of betel quid are arecoline from betel nuts and copper, which are responsible for fibroblast dysfunction and fibrosis. A variety of extracellular and intracellular signaling pathways might be involved. Treatment of OSF is difficult, as not many large, randomized controlled trials have been conducted. The principal actions of drug therapy include antifibrotic, anti-inflammatory, and antioxygen radical mechanisms. Potential new drugs are on the horizon. Surgery may be necessary in advanced cases of trismus. Prevention is most important, as no healing can be achieved with available treatments. Keywords: betel nut, betel quid, oral disease, squamous cell carcinoma, tobacco, fibrosis

    Full Text Available RESUMEN: Habitar las ciudades es un proceso en el que se encuentran anudadas cuestiones materiales y simbólicas. Este lazo debe ser atendido y puesto en valor en términos históricos y culturales ya que forma parte de nuestro aprendizaje como sujetos urbanos. En este sentido, tal como afirma Andreas Huyssen (2002: 191 "...la ciudad funciona como un tipo de prisma" que permite "enfocar" una multiplicidad de temáticas que no están solo ligadas al urbanismo o a la arquitectura, sino también a experiencias culturales y construcciones simbólicas que articulan el hecho concreto de vivir en las ciudades. Es así que, siguiendo a este autor, podemos afirmar que la ciudad es un texto que puede ser leído como un verdadero espacio de signos. Una casa, un barrio, un edificio, los espacios públicos, las calles y veredas, los monumentos son reservorios de un tiempo y una memoria que requieren de una multiplicidad de lecturas para transformarse en escenarios de aprendizajes integradores. Cuestionar a la ciudad como territorio de la educación integral así como reconocer las cuestiones centrales que se ponen a prueba cuando esto se postula como una política pública son los objetivos principales del presente artículo, para lo cual proponemos un recorrido a partir de considerar conceptos nodales como los de educación integral y pedagogía urbana.

    2011-03-15

    A focus often exists in dental practice on the maintenance and management of the dentition and the periodontium, however, conditions of the oral mucosa and orofacial pain can cause significant problems for older patients. Oral mucosal conditions are more prevalent in older patients and many orofacial pain disorders, such as burning mouth syndrome and trigeminal neuralgia, are more common in patients over the age of 50 years. Although these conditions may not be routinely managed in general practice, identification of these patients in primary care and appropriate referral will lead to more prompt and effective treatment. CLINICAL RELEVANCE: Dental practitioners need to be able to identify what is considered to be within the normal physiological limits of the ageing oral tissue and hence what is abnormal and requires further investigation to facilitate appropriate referral.

    Gastrophysics is the science that pertains to the physical and physico-chemical description of the empirical world of gastronomy, with focus on sensory perception in the oral cavity and how it is related to the materials properties of food and cooking processes. Flavor (taste and smell), mouthfeel, chemesthesis, and astringency are all related to the chemical properties and the texture of the food and how the food is transformed in the oral cavity. The present topical review will primarily focus attention on the somatosensory perception of food (mouthfeel or texture) and how it interacts with basic tastes (sour, bitter, sweet, salty, and umami) and chemesthetic action. Issues regarding diet, nutrition, and health will be put into an evolutionary perspective, and some mention will be made of umami and its importance for (oral) health.

He was completely relieved in three days and tapered off the drug thereafter. A further attack of proctalgia fugax after a month was again treated successfully with oral clonidine. The presumed aetiology of proctalgia fugax is discussed and the possible mechanism of action of clonidine in this condition is outlined. Further trials of clonidine appear to be worthwhile for this condition which has been described as incurable.

    Combined oral contraceptive (COC) use has been associated with venous thrombosis (VT) (i.e., deep venous thrombosis and pulmonary embolism). The VT risk has been evaluated for many estrogen doses and progestagen types contained in COC but no comprehensive comparison involving commonly used COC is available. To provide a comprehensive overview of the risk of venous thrombosis in women using different combined oral contraceptives. Electronic databases (Pubmed, Embase, Web of Science, Cochrane, CINAHL, Academic Search Premier and ScienceDirect) were searched in 22 April 2013 for eligible studies, without language restrictions. We selected studies including healthy women taking COC with VT as outcome. The primary outcome of interest was a fatal or non-fatal first event of venous thrombosis with the main focus on deep venous thrombosis or pulmonary embolism. Publications with at least 10 events in total were eligible. The network meta-analysis was performed using an extension of frequentist random effects models for mixed multiple treatment comparisons. Unadjusted relative risks with 95% confidence intervals were reported.Two independent reviewers extracted data from selected studies. 3110 publications were retrieved through a search strategy; 25 publications reporting on 26 studies were included. Incidence of venous thrombosis in non-users from two included cohorts was 0.19 and 0.37 per 1 000 person years, in line with previously reported incidences of 0,16 per 1 000 person years. Use of combined oral contraceptives increased the risk of venous thrombosis compared with non-use (relative risk 3.5, 95% confidence interval 2.9 to 4.3). The relative risk of venous thrombosis for combined oral contraceptives with 30-35 μg ethinylestradiol and gestodene, desogestrel, cyproterone acetate, or drospirenone were similar and about 50-80% higher than for combined oral contraceptives with levonorgestrel. A dose related effect of ethinylestradiol was observed for gestodene

    Full Text Available Oral lesions are among the early signs of HIV infection and can predict its progression to acquired immunodeficiency syndrome (AIDS. A better understanding of the oral manifestations of AIDS in both adults and children has implications for all health care professionals. The knowledge of such alterations would allow for early recognition of HIV-infected patients. The present paper reviews epidemiology, relevant aspects of HIV infection related to the mouth in both adults and children, as well as current trends in antiretroviral therapy and its connection with orofacial manifestations related to AIDS.

    2015-07-01

    Cancer of the oral cavity is one of the most common malignancies worldwide. Although early diagnosis is relatively easy, presentation with advanced disease is not uncommon. The standard of care is primary surgical resection with or without postoperative adjuvant therapy. Improvements in surgical techniques combined with the routine use of postoperative radiation or chemoradiation therapy have resulted in improved survival. Successful treatment is predicated on multidisciplinary treatment strategies to maximize oncologic control and minimize impact of therapy on form and function. Prevention of oral cancer requires better education about lifestyle-related risk factors, and improved awareness and tools for early diagnosis. Copyright © 2015 Elsevier Inc. All rights reserved.

    2009-08-01

    Full Text Available La Úlcera Eosinófila de la Mucosa Oral, es una entidad poco frecuente, pobremente descrita en la literatura mundial. Se define como una lesión benigna autolimitada que si bien puede presentarse en distintas áreas de la cavidad bucal, presenta una marcada predilección por la mucosa ventral de la lengua. Clínicamente, se presenta como una lesión ulcerada de bordes indurados y sobreelevados. Los hallazgos histopatológicos son característicos y consisten en un infiltrado mixto rico en eosinófilos, acompañado de una población de grandes células mononucleadas. Recientes artículos basados en estudios inmunohistoquimicos, permiten afirmar la presencia de grandes linfocitos atípicos CD30+ y por lo tanto, incluir esta lesión en el espectro de las entidades simuladoras de desordenes linfoproliferativos. A pesar de esto, el mecanismo etiopatogenico permanece oscuro y el trauma local juega un rol todavía no dilucidado; aunque se halla presente en la mayoría de las publicaciones, explicando el fenómeno como un mecanismo reactivo. La importancia de esta lesión, radica en su diagnostico diferencial por su semejanza clínica al carcinoma espinocelular, histoplasmosis, chancro sifilítico, Úlcera tuberculosa, carcinoma epidermoide y otras. En nuestro trabajo se revisa la literatura y se discuten la características clínicas, histopatológicas y alternativas terapéuticas, a partir del artículo de un caso clínico en una paciente joven, que luego de la biopsia escisión como método para el diagnostico de certeza, se produce una recidiva de la lesión; lo que orientó el tratamiento hacia la cirugía combinada con corticoterapia local intralesional, logrando su remisión.Eosinophilic Ulcer of the Oral Mucosa, an entity, poorly deciphers in world-wide literature.

  19. MIGRAÇÃO COMO CRIME, ÊXODO COMO LIBERDADE

    Directory of Open Access Journals (Sweden)

    Aryadne Bittencourt Waldely

    Full Text Available Resumo O tratamento securitário dispensado à migração – e aos deslocamentos em geral, incluindo o refúgio – não é excepcional nem secundário. Se a criminalização aparece como evento extraordinário, isso quer dizer apenas que as práticas de securitização não se limitam à punição e que não são exclusivas das instituições de repressão. Ao contrário, estão espalhadas por diversos dispositivos institucionais, práticas e discursos. No caso dos migrantes, refugiados e deslocados em geral, o que está em questão não é exatamente reprimir ou interditar, mas classificar os fluxos, os atos e os sujeitos e docilizar os corpos. E é a fuga em si mesma – seja o deslocamento voluntário ou não – que se torna objeto de tais dispositivos. Neste sentido, é preciso analisar e qualificar os eventos em relação à sua potência e à sua importância política: a criminalização e todos os atos de repressão, docilização e captura são reativos e secundários em relação à fuga; enquanto a fuga é o ato primeiro, o movimento antecedente e capaz de produzir liberdade, justiça e direitos.

    Data sourcesCochrane Oral Health Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, CANCERLIT, CINAHL, the US National Institutes of Health Trials Registry and the WHO Clinical Trials Registry Platform.Study selectionRandomised controlled trials (RCTs) assessing the effects of oral cryotherapy in patients with cancer receiving treatment compared to usual care, no treatment or other interventions to prevent mucositis. The primary outcome was incidence of mucositis and its severity.Data extraction and synthesisTwo reviewers carried out study assessment and data extraction independently. Treatment effect for continuous data was calculated using mean values and standard deviations and expressed as mean difference (MD) and 95% confidence interval. Risk ratio (RR) was calculated for dichotomous data. Meta-analysis was performed.ResultsFourteen studies with 1280 participants were included. Subgroup analysis was undertaken according to the main cancer treatment type. Cryotherapy reduced the risk of developing mucositis by 39% (RR = 0.61; 95%CI, 0.52 to 0.72) on patients treated with fluorouracil (5FU). For melphalan-based treatment the risk of developing mucositis was reduced by 41% (RR =0.59; 95%CI, 0.35 to 1.01). Oral cryotherapy was shown to be safe, with very low rates of minor adverse effects, such as headaches, chills, numbness/taste disturbance and tooth pain. This appears to contribute to the high rates of compliance seen in the included studies.ConclusionsThere is confidence that oral cryotherapy leads to a large reduction in oral mucositis in adults treated with 5FU. Although there is less certainty on the size of the reduction on patients treated with melphalan, it is certain there is reduction of severe mucositis.

    Full Text Available Background: Oral health is a crucial factor for overall well-being and there is a mutual relationship between nutrition and oral health. The aim of this study was to review the publications which have examined the association between nutrition or diet and oral health status or oral disease in Iran. Methods: The electronic databases of PubMed, Scopus, Google scholar, scientific information database (SID, and Magiran were searched using key words of diet, nutrition, oral health, oral disease, and Iran to reach the related articles published up to 2016. The English and Persian articles with cross-sectional, clinical trial, prospective, and case-control designs were selected. The Persian studies were then translated into English. The animal studies were not investigated. Results: The findings showed that nutrition and diet were associated with oral health. However, the majority of studies focused on evaluation of the relation between nutrition and dental caries. Further, a few studies were conducted on the association between nutrition and other oral problems such as periodontal disease or oral cancer. Moreover, the limited nutritional or dietary factors were investigated in the literature. Conclusions: Nutrition and diet are related to oral health and prevention of oral disease. Further studies are therefore recommended to evaluate the association between nutrition and oral health with considering various dietary or nutritional factors and different types of oral problems in Iran.

    Various distresses appear in the terminal stage of cancer. Oral problems including dry mouth, stomatitis and candidiasis are one of the important problems which should be resolved. The purpose of this study was to investigate oral problems in this stage and improvement of dry mouth by oral care. The study subjects were consecutive terminally ill cancer patients admitted over the past 2 years. Patients were divided based on the status of oral food intake into good oral food intake group (≥30%) and poor oral food intake group. The following 3 items were retrospectively investigated: 1) The incidences of these oral problems, 2) Severity of dry mouth and complication with other oral problems, 3) Improvement of dry mouth using standard oral care by nursing staff and specialist oral care including dentists as needed. There were 115 and 158 patients in good and poor oral intake groups, respectively. 1) The incidences of dry mouth, stomatitis, and candidiasis were significantly higher in poor oral intake group ( p oral intake groups, respectively ( p oral intake group ( p = 0.0002). 3) The rate of dry mouth improvement by oral care was 100% in Grade-1, 86% in Grade-2 and 81% in Grade-3. Oral problems occur in many of terminally ill cancer patients. Accurate diagnosis of oral problems and corresponding appropriate interventions are important for improving quality of end-of-life care.

    As early as 900 years ago, the Bedouins of the Negev desert were reported to kill a rabid dog, roast its liver and feed it to a dog-bitten person for three to five days according to the size and number of bites [1] . In sixteenth century China, physicians routinely prescribed pills made from the fleas collected from sick cows, which purportedly prevented smallpox. One may dismiss the wisdom of the Bedouins or Chinese but the Nobel laureate, Charles Richet, demonstrated in 1900 that feeding raw meat can cure tuberculous dogs - an approach he termed zomotherapy. Despite historical clues indicating the feasibility of oral vaccination, this particular field is notoriously infamous for the abundance of dead-end leads. Today, most commercial vaccines are delivered by injection, which has the principal limitation that recipients do not like needles. In the last few years, there has been a sharp increase in interest in needle-free vaccine delivery; new data emerges almost daily in the literature. So far, there are very few licensed oral vaccines, but many more vaccine candidates are in development. Vaccines delivered orally have the potential to take immunization to a fundamentally new level. In this review, the authors summarize the recent progress in the area of oral vaccines.

    1971-05-01

    A sample of 139 predominantly black, young, low-income patients who had accepted oral contraception at a publicly supported family planning clinic has been analyzed for correlates of oral contraception continuation. Interviews were conducted 10-12 months after the clinic visit; at this time 38% of the patients continued taking oral contraceptives. It was found that patients with the highest continuation rates were 18-24 years old, in the 2-3 parity group, living with their husbands, had low-parity mothers, and were able to fill prescriptions in less time with more convenient methods of transportation. Discontinuers tended to have high-parity mothers, live with parents or head their own households, and to be in the 13-17 or 25-45 year old age groups. Fear of long-term use of oral contraceptives and perceived side effects appeared to be implicated in discontinuation. The rate of discontinuation may be associated with irregular coital experience and less consistent exposure to pregnancy.

  1. Poetry as an oral outlet

    Directory of Open Access Journals (Sweden)

    Abraham Arden Brill

    2013-02-01

    Full Text Available The text is inspired by some of Freud’s observations, regarding, among other things, the pleasure the child takes from playing with words as preliminary degree of wit. As zealous follower, Brill extends and intensifies the importance of Freud’s thought trying to establish a link, or at least a point of contact between the poetry in a generic sense and the various forms of oral gratification. This gives rise to unusual associations that are for the contemporary reader slightly comical: if poetry can be seen as an expression of the mysteries of oral Erotica, the relationship between poet and gourmet can only be the closest. To define and limit the scopes of fulfillment that is realized in oral poetry, Brill passes rapidly through the various forms this satisfaction takes in neurotics, in psychotics, in the child, in the primitive. The conclusions, unfortunately, are very general: many poets do not go beyond the oral stage and give clear signs of a fixation of libidinal development at this level.

  6. Oral Lactobacilli and Dental Caries

    Lactobacilli have been associated with dental caries for over a century. Here, we review the pertinent literature along with findings from our own study to formulate a working hypothesis about the natural history and role of lactobacilli. Unlike most indigenous microbes that stably colonize a host, lactobacilli appear to be planktonic, opportunistic settlers that can gather and multiply only in certain restrictive niches of the host, at least within the oral cavity. We postulate that the following essential requirements are necessary for sustained colonization of lactobacilli in humans: 1) a stagnant, retentive niche that is mostly anaerobic; 2) a low pH milieu; and 3) ready access to carbohydrates. Three sites on the human body meet these specifications: caries lesions, the stomach, and the vagina. Only a handful of Lactobacillus species is found in caries lesions, but they are largely absent in caries-free children. Lactobacilli present in caries lesions represent both a major contributor to caries progression and a major reservoir to the gastrointestinal (GI) tract. We extend the assertion from other investigators that lactobacilli found in the GI tract originate in the oral cavity by proposing that lactobacilli in the oral cavity arise from caries lesions. This, in turn, leads us to reflect on the health implications of the lactobacilli in the mouth and downstream GI and to ponder whether these or any of the Lactobacillus species are truly indigenous to the human GI tract or the oral cavity.

    Full Text Available O foco deste trabalho é refletir sobre a montagem cinematográfica como ato criativo, não a montagem pensada como simples agenciadora de planos, mas como criadora de sentidos. É na maneira como o cinema articula e aproxima as imagens e os sons que verificamos sua transformação em discurso. Criam-se novos sentidos, uma nova lógica onde os significados não são transparentes, nascida da associação de fragmentos. Justapõem-se duas realidades: a da vida propriamente dita e a do filme, a do discurso e, ainda dentro do filme, a justaposição de planos determinando novas leituras das Imagens. Partindo dos princípios da teoria da montagem cinematográfica de S. M. Eisenstein, faremos um rápido panorama de como o cinema, no decorrer de sua história, foi influenciado pelos conceitos desenvolvidos em sua teoria.

    Full Text Available ResumoEste artigo considera como o estudo da cultura e da aprendizagem pode ser de particular relevância para o campo da antropologia sociocultural em geral. O termo mais importante na expressão “cultura & aprendizagem” talvez seja o logograma “&” – ou seja, coloca-se a questão sobre o que conecta cultura e aprendizagem, perguntando-se como esses termos estão relacionados. Como devemos compreender cultura e aprendizagem como instâncias produtoras delas próprias, e uma da outra, na prática? Recalibrando em termos relacionais, podemos dizer que não é possível abordar a “aprendizagem” ou “cultura e aprendizagem” sem o seu emaranhamento na vida político-econômica, nas lutas e disputas históricas, em suas coerências e incoerências, e na produção relacional e histórica da vida cotidiana. Através das lentes da teoria da prática social, os estudos etnográficos sobre aprendizagem na prática oferecem diferentes entendimentos sobre como certa vida e certas disputas e incoerências são produzidas.

    Oral films, namely buccal mucoadhesive films and orodispersible films represent innovative formulations for administration of a wide range of drugs. Oral films show many advantageous properties and are intended for systemic drug delivery or for local treatment of the oral mucosa. In both cases, the film represents a thin layer, which could be intended to adhere to the oral mucosa by means of mucoadhesion; or to rapid dissolution and subsequent swallowing without the need of liquid intake, in the case of orodispersible films. Main constitutive excipients are film-forming polymers, which must in the case of mucoadhesive forms remain on the mucosa within the required time interval. Oral films are currently available on the pharmaceutical market and could compete with conventional oral dosage forms in the future. oral cavity oral films buccal mucoadhesive films orodispersible films film-forming polymers.

    Leukemia is the most common neoplastic disease of the white blood cells which is important as a pediatric malignancy. Oral manifestations occur frequently in leukemic patients and may present as initial evidence of the disease or its relapse. The symptoms include gingival enlargement and bleeding, oral ulceration, petechia, mucosal pallor, noma, trismus and oral infections. Oral lesions arise in both acute and chronic forms of all types of leukemia. These oral manifestations either may be the result of direct infiltration of leukemic cells (primary) or secondary to underlying thrombocytopenia, neutropenia, or impaired granulocyte function. Despite the fact that leukemia has long been known to be associated with oral lesions, the available literature on this topic consists mostly of case reports, without data summarizing the main oral changes for each type of leukemia. Therefore, the present review aimed at describing oral manifestations of all leukemia types and their dental management. This might be useful in early diagnosis, improving patient outcomes.

    Full Text Available Dental plaque is still considered the main etiological factor for periodontal diseases. Our understanding of periodontal disease has advanced from the previous concepts where gingivitis slowly progressed to periodontitis to a more complex scenario that correlates several risk factors in the pathogenesis of periodontal disease. Among these factors, age has been associated with increased rates of periodontal disease as the population gets older. Although the loss of alveolar bone and periodontal attachment is common in the elderly population, and there is evident age-related changes in the periodontium, severe periodontitis is not a natural consequence of ageing. The importance of identifying the risk factors that participate in the pathogenesis of periodontal disease at an early phase, both of the individual and the disease, as well as evaluating the capacity of the individual to control dental plaque will enable the implementation of an adequate preventive program, where the needs and limitations of the individual are considered to specifically tailor the oral hygiene procedures and the mouthwashes to be used.La placa dental es aún considerada el factor etiológico primario de la enfermedad periodontal. La etiopatogenia de esta enfermedad ha avanzado del concepto anterior donde una gingivitis progresaba lentamente a una periodontitis, a un escenario más complejo donde varios factores de riesgo se correlacionan. Dentro estos factores, el envejecimiento ha sido asociado con mayores porcentajes de enfermedad periodontal a medida que la población envejece. Aunque la pérdida ósea y de inserción es común en el adulto mayor y los cambios del periodonto son evidentes con la edad, la enfermedad periodontal severa no es una consecuencia natural del envejecimiento.

    The aim of this study is to determine relationship between oral hygiene and colonisation of Candia species in oral cavity. Maintenance oral hygiene is reducing pathological agents in the mouth and preventing violation of oral health. Study included 140 patients. For oral hygiene assessement were used the dental plaque index, oral hygiene index and dental calculus index. Ph test strips were used to determine pH of saliva. For isolation of Candida species oral swabs were taken to all patients. It was found out that pH of oral cavity does not varies notably, no matter of oral hygiene level. Candida species were identified in 28.6% respondents. The most present were Candida albicans, in 85% cases. The presence of plaque, tartar and high index oral hygiene (IOH) in patients with Candida is statistically significant. It was found that 83.4% of patients with Candida poorly maintained oral hygiene. Poor oral hygiene is associated with a significantly higher score in the presence of tartar, plaque and high IOH. In total patient's population 67% has amalgam fillings. Presence of amalgam fillings in patients with identified Candida was statistically significant. This study indicates low level of oral hygiene. Correlation between presence of Candida species and poor oral hygiene was proved. Also Candida was more present among patients with amalgam fillings. Improvement of oral hygiene is necessery for oral health and health in general, as well.

    Trascendiendo las diversas presentaciones posibles del autismo, ya la psiquiatría clásica recortaba rasgos constantes, invariantes que se desplegaban en todos los casos. Estos fenómenos en cuestión fueron considerados desde la fundación del cuadro clínico por Leo Kanner en 1943, como gravísimos trastornos. A pesar de que además de aparecer de manera drástica impregnando el cuadro también surgían en otros casos al modo de rasgos discretos y sutiles - como lo mencionaba Hans Asperger en las des...

    Interviews were conducted with 294 black residents (155 females and 138 males) of a peri-urban informal settlement in Gauteng to ascertain utilisation of oral health services, oral health needs and oral health status. Only 37 per cent of the sample had consulted a dentist or medical practitioner, usually for extractions. Teenagers and employed persons were significantly less likely to utilise dentists than the older age groups and unemployed persons. Forty per cent were currently experiencing oral health problems such as a sore mouth, tooth decay and bleeding/painful gums. Two hundred and twelve (73 per cent) interviewees wanted dental treatment or advice. Residents who rated their oral health status as fair or poor appeared to have the greatest need for oral health services. The use of interviews appears to be a cost-effective method of determining oral morbidity.

    Full Text Available En este artículo se discute la información obtenida respecto del cuidado enfermero brindado a personas portadoras de Diabetes Mellitus tipo 2 relacionada con la elevación de la hemoglobina glicolisada (Hba1c como factor pronóstico para el desarrollo de complicaciones. Se realizó una búsqueda de la mejor información científica disponible para construir el estado de la cuestión. Posteriormente, se estableció una pregunta en formato PICO (pacientes, intervención, comparación, observación y se procedió a establecer estrategias de búsqueda en las diferentes bases de datos sugeridas en el Curso de Práctica Clínica de Enfermería Basada en la Evidencia impartido por CIEBE-CR, entre las que se encuentran PUBMED, EBSCO HOST, principalmente. El análisis crítico se llevó a cabo mediante las recomendaciones que brinda CASPe y se comparó con la práctica realizada en el Hospital de la Anexión. El control intensivo de la glicemia, el cual incluye agentes orales, la insulina y la intervención cardiovascular múltiple reflejada en hemoglobinas glicosilada menores a 7, indicó que existía una evidente disminución en la incidencia de eventos macrovasculares mayores tales como el infarto agudo al miocardio, el ictus no fatal y el accidente vascular cerebral. De acuerdo con la evidencia, mantener la hemoglobina glicosilada dentro de parámetros normales disminuye el riesgo de sufrir complicaciones macrovasculares de esta patología en comparación con aquellos pacientes que manejan hemoglobina glicosiladaalta.

    Full Text Available INTRODUCCIÓN: El tumor de Masson o hemangioendotelioma vegetante intravascular, es una hiperplasia endotelial  papilar hacia el interior del vaso pudiendo ocluirlo y trombosarlo con necrosis e infartos locales, constituyendo tumoraciones rojizas irregulares bien delimitadas de localización preferente en piel y riñón, siendo muy raros en cavidad oral. Son elásticos no indurados, depresibles y frágiles, con crecimiento lentamente progresivo . MATERIAL Y MÉTODOS:Presentamos dos casos . Varón afecto de hematemesis repetidas sin identificarse origen inicialmente, demostrándose tumor de Masson de paladar duro oculto por prótesis dental, que fue resecado mediante pinza bipolar previa infiltración con suero perilesional para devascularizarlo. El segundo fue una mujer  que en relación con la ingesta presentó cuadro de hematemesis importante. La valoración de Urgencias y la endoscopia digestiva no identificaron el origen del sangrado en tubo digestivo, aunque la endoscopista identificó nuevo sangrado desde cavidad oral. La exploración ORL objetivó una pequeña tumoración rojiza de apariencia vascular en zona de mordida izquierda, sangrante al mínimo roce, cuya resección se realizó de urgencia sin incidencias, con idéntica técnica y diagnóstico anatomopatológico. Posteriormente, se constató el antecedente de episodios previos de menor cuantía. DISCUSIÓN: Los tumores de Masson son muy raros en tubo digestivo y excepcionales en cavidad oral. Se han relacionado con irritaciones repetidas o traumatismos locales,hematomas encapsulados o preexistencia de otras lesiones vasculares. Estos factores parecen haber acontecido en nuestros pacientes (roce de prótesis dental en paladar y mordidas de repetición. Son masas de lento crecimiento en las que se producen con frecuencia fenómenos trombóticos. Sin embargo, el roce de su superficie puede dar lugar a sangrados importantes como en estos casos. Deben diferenciarse de tumores

    Current biomarkers (DNA, RNA and protein) for oral cavity and oropharyngeal cancers demonstrate biological variations between individuals, rendering them impractical for clinical translation. Whilst these biomarkers originate from the host, there is not much information in the literature about the influence of oral microbiota on cancer pathogenesis, especially in oral cancers. Oral microbiotas are known to participate in disease initiation and progression not only limited to the oral cavity, ...

En este sentido se desarrolló un estudio de toxicidad aguda oral, con el objetivo de determinar sus efectos adversos. Se administró una dosis de 2 000 mg/kg de peso corporal a un grupo de ratas (3 hembras y 3 machos y el vehículo a otro grupo utilizado como control. Los animales se mantuvieron en observación durante 14 días, se determinaron las variaciones de peso, la presencia o no de síntomas y signos clínicos, y la necropsia al finalizar el estudio. Como resultado no se observó disminución del peso corporal en ninguno de los grupos experimentales, presentaron síntomas como: piloerección, respiración acelerada, actividad disminuida, acicalamiento, aislamiento a la esquina de la caja y la muerte de un animal. El análisis macroscópico de los órganos no detectó variación alguna.

    Dentists are at the forefront for screening oral cancer. In addition to the well known carcinogenic potential of tobacco and alcohol, betel nut chewing and human papilloma virus are important risk factors in the development of oral cancer. To aid in screening and decreasing morbidity and mortality from oral cancer, a variety of techniques have been developed. These techniques show promise but they require additional investigations to determine their usefulness in oral cancer detection. Dentists need to be well educated and vigilant when dealing with all patients they encounter. Early detection, diagnosis and treatment are critical for the effective management of oral cancers.

    Podoplanin is a type I transmembrane sialomucin-like glycoprotein that is specifically expressed in lymphatic endothelial cells. Studies have shown that assessment of podoplanin expression in the epithelial cells can be used to predict the malignant transformation of potentially malignant disorders and the metastatic tendency of primary head and neck squamous cell carcinoma. The aim of our study was to compare the expression of podoplanin in oral leukoplakia, oral submucous fibrosis and oral squamous cell carcinoma with that in normal buccal mucosa by immunohistochemical methods. Immunohistochemical expression of podoplanin was analyzed in 20 cases each of oral leukoplakia, oral submucous fibrosis, oral squamous cell carcinoma and normal buccal mucosa, with monoclonal antibody D2-40. The expression of podoplanin was graded from grade 0-4. There was a statistically significant upregulation of the grades of podoplanin expression in oral squamous cell carcinoma(100%), oral submucous fibrosis (90%) and oral leukoplakia (65%) when compared to that in normal mucosa(35%). Podoplanin expression increased with decrease in grades of differentiation in oral squamous cell carcinoma . Podoplanin expression in the samples of oral submucous fibrosis was higher than that in oral leukoplakia. Evaluation of podoplanin expression in the epithelial cells of oral dysplastic lesions may provide valuable information to predict their risk of malignant transformation. Key words: Immunohistochemistry, Oral leukoplakia, Oral submucous fibrosis, Podoplanin, Squamous cell carcinoma.

    Many workplace-based health promotion programmes have been reported but only a few include or focus specifically on oral health. Although certain obstacles to oral health promotion in the workplace exist from the management side, from the dental profession and from the employees, these seem...... to be of a scale that can easily be overcome: moreover, numerous potential benefits exist. From the employer's point of view, the main arguments in favour are reduced health care costs, increased productivity and reduced absenteeism. The benefits to the dental profession are possible increases in utilization...... of services and less restraint from fee payment structures and physical environments. The immediate benefit to the employees is easy access to dental services. In addition, work-related dental hazards can be compensated for or prevented and screening activities can be more easily organized. The literature...
