    Full Text Available FUNDAMENTO: El uso de métodos anticonceptivos está en relación, entre otros, con factores demográficos, sociales, económicos, educativos e ideológicos. El objetivo de este trabajo es conocer qué métodos anticonceptivos conocen las mujeres en edad fértil, así como la prevalencia de su uso. MÉTODOS: A partir del listado de tarjeta sanitaria se seleccionaron mediante muestreo sistemático 389 de las 5800 mujeres en edad fértil (15-45 años asignadas a un centro de salud. Previo envío de una carta, comunicando el motivo del estudio, se contactó telefónicamente con ellas para la realización de una encuesta, la cual incluía preguntas acerca del conocimiento y uso de métodos anticonceptivos, características socioculturales y actividad sexual. Las mujeres que no tenían teléfono fueron citadas en el centro de salud. RESULTADOS: Se contactó con 178 mujeres, de las que participaron 166 (tasa de respuesta de 42,7%. De ellas utilizaban algún método anticonceptivo 86 (51,8%; IC:44,2-59,4%. Sin embargo, entre mujeres con riesgo de embarazo no deseado, la prevalencia de uso era del 70,5% (IC: 62,4-78,6%, destacando el hecho de que en el grupo de mujeres de 40 a 45 años sólo utilizaran anticonceptivos el 45,4%, con una frecuencia significativamente inferior a los otros grupos de edad. Los métodos más conocidos eran el preservativo (90,4%, los contraceptivos orales (89,2% y el dispositivo intrauterino (78,3%, siendo escaso el conocimiento de otros métodos. CONCLUSIONES: La tasa de utilización de métodos anticonceptivos en mujeres con riesgo de embarazo no deseado es aceptable, si bien entre 40 y 45 años es llamativamente baja. Los métodos más conocidos son el preservativo, los contraceptivos orales y el dispositivo intrauterino.

    Full Text Available OBJETIVO: Avaliar as razões para descontinuar diversos anticoncepcionais orais combinados entre mulheres brasileiras iniciantes do método, residentes em áreas urbanas. MÉTODOS: Estudo de corte transversal com 400 ginecologistas do Brasil, registrados na Federação Brasileira de Ginecologia e Obstetrícia. Cada médico entrevistou 10 mulheres não grávidas, não lactantes, não em amenorreia, com idades entre 18 e 39 anos que consultavam solicitando anticoncepcional oral combinado (ACO, com um questionário no início de uso e aos 6 meses posteriores. O questionário incluiu dados sociodemográficos, tipo de ACO escolhido ou prescrito e razões para descontinuação, caso ocorresse durante o seguimento. A estratégia de seleção permitiu a inclusão de mulheres de diferentes estratos socioeconômicos, mas somente atendidas em consultórios privados ou de convênios. O tamanho da amostra foi estimado em 1.427 mulheres. RESULTADOS: Foram obtidas 3.465 entrevistas na primeira visita e 1.699 aos 6 meses posteriores. As mulheres tinham predominantemente entre 20 e 29 anos, 57,3% eram solteiras e em proporção quase igual de 45% tinham ensino médio ou superior. A maioria (60,7% era nuligestas e dentre as que tinham usado algum método contraceptivo anteriormente, 71,8% tinham utilizado ACO. Entre os ACO mais prescritos ou escolhidos, o mais prevalente foram os monofásicos com etinilestradiol (20 µg e no tocante ao progestágeno, o mais prevalente foi com gestodeno (36,5%, seguido por ACO com drosperinona (22,0%. Aos 6 meses, 63,5% continuavam em uso do ACO. Dentre as que descontinuaram o uso, as principais razões dadas foram: desejo de engravidar (36,5% e efeitos colaterais (57,3% como cefaléia (37,6%, aumento de peso (16,6% e sangramento irregular (23,6%. CONCLUSÕES: A taxa de continuação do uso de ACO foi baixa aos seis meses e este estudo pode contribuir para que os médicos orientem melhor suas pacientes iniciantes no uso de ACO

  6. EFECTO ABORTIVO DE LOS ANTICONCEPTIVOS HORMONALES: UNA REVISIÓN

    PAU AGULLES SIMÓ

    2015-01-01

    Full Text Available En gran parte de la comunidad científica, así como del ámbito jurídico, al tratar del embrión no nacido, está vigente el criterio según el cual hay que definir el embarazo como el período que comprende sólo desde la implantación hasta el nacimiento natural. Esto lleva consigo otras novedades; por ejemplo, la redefinición de aborto como la eliminación del embrión sólo en ese período, o la extensión de la anticoncepción a cualquier medio que impida la unión entre los gametos como consecuencia de una relación íntima, o también que elimine el producto de la concepción antes de su implantación. De modo que la industria farmacéutica está lanzando al mercado, bajo el nombre de anticonceptivos, productos que actúan también mediante un mecanismo antiimplantatorio. Este hecho tiene grandes repercusiones éticas con relación al respeto del embrión, que obligan a reflexionar acerca de la valoración moral de la prescripción, dispensación y uso de estos medios. Ahora bien, ¿cuáles de los medios contraceptivos actualmente presentes en el mercado incluyen un efecto antiimplantatorio?, ¿qué mecanismos contribuyen a su acción farmacológica y en qué medida lo hacen? Esto es lo que hemos estudiado en este artículo, basándonos en la bibliografía científica disponible. Aunque no ha sido una tarea sencilla, puesto que los resultados aportados por la literatura varían mucho, se ha tratado de ofrecer una conclusión bastante precisa. Básicamente hemos cumplido un doble objetivo: actualizar y completar los estudios —pocos, parciales o lejanos en el tiempo— que tenían este mismo objeto; y ofrecer una valoración ética respecto al respeto de la vida naciente del uso de los anticonceptivos hormonales que pueden tener efecto antiimplantatorio.

Con este análisis se pretende evidenciar el rol que desempeñan las diversas características sociodemográficas de los jóvenes en el conocimiento y uso de anticonceptivos, con partic cular atención en el papel que juega el género. En general se observan diferencias importantes entre los factores relacionados con el uso de anticonceptivos alguna vez y los factores asociados al uso del condón en las relaciones con la pareja actual.

  16. Cómo y cuando el levonorgestrel previene el embarazo cuando se administra como anticonceptivo de emergencia

    Directory of Open Access Journals (Sweden)

    Ortiz, Maria Elena

    2007-01-01

    Full Text Available La anticoncepción hormonal de emergencia (AHE es uno de los pocos recursos que la mujer puede usar para prevenir un embarazo no deseado después de haber tenido una relación sexual en la que no usó método anticonceptivo o el que usó presentó una falla. Actualmente, el método preferido para la AHE es la píldora que contiene solamente levonorgestrel (LNG. Según la OMS, puede prevenir embarazos si se usa hasta 120 horas después del acto sexual, pero su eficacia disminuye drásticamente desde 85% a 31% mientras más se posterga su administración. La introducción de la AHE ha generado controversia en muchos países latinoamericanos por la percepción errónea de que induce aborto y la oposición de los sectores más conservadores de la sociedad que temen que favorezca la promiscuidad. Con el propósito de dar a conocer la evidencia científica producida por las investigaciones diseñadas para dilucidar como el LNG previene el embarazo cuando se administra como AHE, y su correcta interpretación, este artículo analiza críticamente dichos estudios y explica además en que circunstancias este método no logra prevenir el embarazo. El conjunto de la evidencia indica que LNG previene el embarazo solamente cuando impide la fecundación y descarta que el prevenga el embarazo interfiriendo con la implantación del embrión, por lo que la creencia de que es abortivo no tiene sustento científico.

    de metales. Finalmente, en los nuevos esquemas de refinacion del petroleo se preve utilizar la coquizacion para aprovechar mejor el ondo de barril. El residuo producto de este proceso, conocido como coque de refineria, tiene un bajo valor comercial, un poder calorifico elevado y un alto contenido de azufre y metales. La gasificacion ha sido desarrollada en las ultimas dos decadas, en los paises altamente industrializados, como una alternativa para la generacion eficiente y limpia de electricidad a partir de combustibles sucios, asi como para la obtencion de ciertos combustibles en lugares donde no se tiene acceso al petroleo, pero si al carbon. Esta tecnologia cumple los reglamentos mas estrictos del mundo en lo que a emisiones contaminantes se refiere y es la unica solucion, junto a los lechos fluidizados, para los problemas que presentan algunos combustibles que son dificiles de quemar con tecnologias convencionales, como el carbon mineral, el coque de petroleo e incluso los residuos liquidos de la refinacion. Con base en los anterior, es posible pensar en la integracion de esta tecnologia a una planta de ciclo combinado para la generacion de electricidad o a una refineria generando vapor, energia electrica, hidrogeno y otros insumos a un costo competitivo, de manera tal que se resuelven los problemas de manejo y almacenamiento de los residuos; por otro lado se maximiza el aprovechamiento de los recursos energeticos primarios en el pais.

    Full Text Available Introducción. El objetivo de este trabajo es relacionar conocimientos previos (pre-saberes acerca de métodos anticonceptivos con los conocimientos adquiridos (saberes, después una intervención educativa con simulador.Método. Es un estudio realizado con 295 adolescentes escolarizados que cursan noveno, décimo y undécimo en una institución educativa pública. Es de tipo descriptivo. El proceso estuvo compuesto por tres fases; en la primera se midió conocimientos o saberes previos acerca de métodos anticonceptivos, mediante un cuestionario auto-informado; en la segunda se definió los contenidos y actividades de intervención para mejorar los conocimientos previos, y en la tercera fase de post-intervención educativa, se reevaluó los saberes adquiridos con el simulador. Resultados. Se detectó que los pre-saberes en métodos anticonceptivos son deficientes independientemente de la edad y la escolaridad, lo cual requiere planeación, desarrollo y evaluación de la estrategia de aprendizaje colectivo y cooperativo mediante talleres. En cuanto a los post-saberes, se obtuvo una calificación de deficientes a regulares, en el caso del condón masculino, mientras que el reconocimiento de métodos modernos como parche, anillo vaginal, dispositivo intrauterino, entre otros, se dio gracias al contacto directo con el simulador.Conclusiones. Se recalca que a pesar de las  diferencias de edad y escolaridad, no hubo hallazgos relevantes que demostraran diferencias de conocimiento. En los pre-saberes, se encontró niveles de conocimiento deficientes sobre métodos anticonceptivos. El uso de simuladores como herramienta de aprendizaje demostró eficacia en los talleres; en cuanto a los simuladores posibilitan la ruptura de la barrera cognitiva, dado que el adolescente, en este caso, puede explorar y adquirir conocimiento al interaccionar con el objeto de aprendizaje.

El universo fue de 87 alumnos matriculados en la escuela y se trabajó con 78 de ellos, a los cuales se les aplicó una encuesta de manera anónima, con preguntas cerradas y validadas por criterios de expertos. Resultados: en ambos sexos se identificaron correctamente los métodos anticonceptivos. Los padres fueron la fuente de información más frecuente y predominaron aquellos que no reconocen la posibilidad de un embarazo con la práctica de algunos juegos sexuales. Conclusiones: el conocimiento por parte de los y las adolescentes de la importancia de la anticoncepción y los métodos anticonceptivos resulta aún insuficiente. Los programas de educación sexual para adolescentes deben reforzar estos aspectos. El protagonismo de los educadores debe ser mayor pues en estas edades se necesita que los transmisores de la información tengan una adecuada preparación que en ocasiones falta en los padres.Background: birth control in adolescence and the prevention of Sexually Transmitted Infections (STI have been a great concern for our National Health System, which has made many efforts in the interest of achieving it.

    con alto valor agregado, como la gasolina, turbosina o diesel, entre otros. Con la nueva reconfiguracion de las refineria mexicanas de Cd. Madero y Cadereyta y proximamente la terminacion de la reconfiguracion de la refineria de Minatitlan, Veracruz, grandes cantidades de coque se estaran produciendo, con la posibilidad de usarlo mediante la tecnologia de gasificacion para producir un gas sintetico limpio (gasl) con caracteristicas energeticas apropiadas para utilizarse como combustible en un ciclo combinado existente en Mexico. En Mexico se han estimado las posibilidades de generacion de energia electrica a partir del uso del coque de petroleo utilizado la tecnologia de gasificacion o usando generadores de vapor de lecho fluidizado, como es el caso de las planta de potencia TEG en Taquin, San Luis Potosi. Tal es el hecho, que actualmente PEMEX refinacion, tiene terminado el proyecto para construir en Tuxpan, Veracruz una refineria procesadora de crudo Maya con un alto contenido de azufre y junto a la termoelectrica de Tuxpan, contemplandose la posibilidad de aplicar el concepto de ciclo combinado con gasificacion integrada (CCGI); con esta infraestructura sera posible consumir el coque generado por las refinerias mexicanas. La generacion electrica esperada es de 500 MW, de los cuales 100 MW seran para consumo propio de la refineria y 400 MW libres para cubrir la demanda de energia electrica de la zona noreste y centro del pais. El coque de petroleo derivado de las refinerias del pais puede ser utilizado para la generacion limpia de electricidad mediante su gasificacion e integracion a una planta de ciclo combinado existente. La ubicacion estrategia del ciclo combinado Tula, el cual se encuentra adyacente a la refineria Miguel Hidalgo presenta la oportunidad de aplicar la tecnologia de gasificacion como una alternativa viable: primeramente, para la utilizacion de coque de petroleo que actualmente se esta produciendo en las refinerias de Mexico o la utilizacion del

    The thermoelectric centrals of the combined cycle type (Brayton Cycle and Rankine Cycle) present a series of opportunities to increase the efficiency of the combined cycle or of the generated power. This paper shows the methodology for the performance of energy balances in a heat recuperator (H. R.), typically employed in the combined cycle stations operating in Mexico, for the assessment of the energy harnessing in the different sections conforming a H. R. The effect of the installation of evaporative coolers and/or an absorption cooling system at the gas turbine compressor intake on the steam generation in the heat recuperator, is evaluated. This extra generation of steam is quantified for its potential use in the same absorption refrigeration system. From the assessment, it follows up that the steam generation in the H.R. is inversely proportional to the ambient temperature and that, although the increased amount of steam generated can not be harnessed in total by the steam turbine, the remaining fraction is good enough to cover the heat demand for the operation of the refrigeration system. [Espanol] Las centrales termoelectricas del tipo ciclo combinado (ciclo Brayton y ciclo Rankine) presentan un conjunto de oportunidades para incrementar la eficiencia del ciclo combinado o bien la potencia generada.

    A description is presented of the operation of the Combined Cycle Power Stations with Integrated Gasification (CCGI) where the use of solid fuels (coal, vacuum residues, petroleum coke, and biomass) or liquids is possible in a thermal power station with the efficiency and many of the own environmental benefits of the combined cycles. The gasification process is analyzed, that is a thermo-chemical process by means of which a fuel that is in solid state or liquid becomes to the gaseous state by means of a partial oxidation and the obtained gas of this process is called synthesis gas (syngas, by its abbreviations in English) that is used in Combined Cycle Power Stations as a substitute for the natural gas. Also the other components of this type of power stations are shown, such as the air separating unit, and some of the modifications that are due to make to adapt a gas turbine so that it uses syngas, and the considerations of their integration with the air separating unit to optimize the operation of the plant are detailed. A comparison of efficiency values of power stations CCGI with the conventional carbon-electric and the power stations of combined cycle that use natural gas is also shown. Finally the emissions of pollutants of SO{sub 2}, NO{sub x} and CO{sub 2} are analyzed. The possibility of using fuels like petroleum coke and vacuum tower residues that are produced in the Cadereyta refinery is studied for the possible construction of a CCGI power station in Mexico.

    The electricity industry traditionally had two thermodynamic cycles for power generation: conventional steam turbine (Rankine cycle) used to supply a base load during the day, and gas turbines (Brayton cycle), for its speed response, normally used to cover peak loads. However, to provide variable peak loads, the gas turbine, as a volumetric machine is affected by the change in air density by changing the combustion temperature. This paper shows the scheme of integration of both systems, that it's known as combined cycle and the different options that would have these power plants, to maintain or increase their power in variable ambient conditions. It analyzes different options, such as: 1. Supplementary fire in the stove. 2. Air cooling intake in the gas turbine (evaporation system or mechanical system). 3. Steam injection in the combustion chamber. [Spanish] La industria electrica tradicionalmente a contado con dos ciclos termodinamicos para generacion electrica: las turbinas convencionales de vapor (ciclo de Rankine) se utilizan para suministrar una carga base durante el dia, y las turbinas de gas (ciclo de Brayton), por su rapidez de respuesta, se utilizan normalmente para cubrir las cargas pico. Sin embargo, para suministrar las cargas variables pico, la turbina a gas, por ser una maquina volumetrica, se ve afectada por el cambio de la densidad del aire de combustion al cambiar la temperatura ambiente. En este trabajo se muestra el esquema de integracion de ambos sistemas, en lo que se conoce como ciclo combinado y las diferentes opciones que tendrian estas plantas de generacion electrica para mantener o incrementar su potencia en condiciones ambiente variable. Para ello se analizan diferentes opciones, tales como: 1.- Combustion suplementaria en el recuperador de calor. 2.- Enfriamiento del aire de admision a la turbina de gas (mediante un sistema de evaporacion o mediante un sistema mecanico). 3.- Inyeccion de vapor a la camara de combustion.

    Day after day the electric power generation tends to be done in the most efficient way in order to diminish the generation costs and the rate of environmental pollution per KWh generated. This paper discusses the application of absorption refrigeration systems for the cooling of the air entering the compressor of a gas turbine in a combined cycle, in order to increase the mass air flow and with it the turbine output. The flows with remanent energy content that are not used in a combined cycle can be used for the operation of the absorption refrigeration system. This way, the required thermal energy for the cooling system is free. With this system it is possible to raise the gas turbine generation output from 5% to 25%. [Espanol] La generacion electrica dia con dia pretende realizarse de la manera mas eficiente posible con el objeto de disminuir los costos de generacion y la tasa de contaminacion ambiental por Kwh generado. En el presente trabajo se introduce la aplicacion de sistemas de refrigeracion por absorcion para el enfriamiento del aire de entrada al compresor de la turbina de gas de un ciclo combinado, con el objeto de aumentar el flujo masico del aire y con ello la potencia de salida de la turbina. Las corrientes con contenido remanente de energia termica que no se usan en una planta de ciclo combinado pueden servir para operar el sistema de refrigeracion por absorcion. De esta manera, la energia termica requerida para el sistema de enfriamiento es gratuita. Con este sistema es posible incrementar la potencia de generacion de la turbina de gas de 5 a 25%.

    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. PMID:27343964

    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. PMID:21325845

    Full Text Available O arroz é classificado como uma planta tolerante ao amônio (NH4+ devido à predominância desse íon nos solos alagados. Entretanto, nas regiões oxidadas do solo e da rizosfera do arroz pode haver a formação de nitrato (NO3- e esta se tornar importante fonte de N para cultura. Este trabalho foi conduzido com o objetivo de avaliar o efeito de diferentes proporções entre os íons NH4+ e NO3- no desenvolvimento do arroz em solução nutritiva. O experimento foi realizado em casa de vegetação no período de janeiro a fevereiro de 2008, em solução nutritiva com as seguintes proporções entre NH4+ e NO3-: 100:0, 75:25, 50:50, 25:75 e 0:100 na concentração de 5,0 mmol L-1 de N. Foi cultivado o genótipo IRGA 417 e avaliado o rendimento de biomassa, os teores de N, K, Ca e Mg na biomassa e na seiva do xilema. Houve toxidez por NH4+ nas proporções de 100:0 e 75:25 e por NO3- nas proporções de 25:75 e 0:100. Na proporção de 50:50 as plantas se desenvolveram normalmente. O suprimento combinado de NH4+ e NO3- aumentou a produção de biomassa em relação ao NH4+ e ao NO3- supridos isoladamente. O NH 4+ na solução reduziu os teores de Ca e Mg na biomassa, porém não influenciou o teor de N e o de K. Já na seiva do xilema houve redução nos teores de K, Ca e Mg, indicando que o NH4+ influenciou na absorção desses cátions. A quantidade total absorvida de N, K, Mg e Ca foi maior com o suprimento combinado de NH4+ e NO3-, indicando que, além de promover melhor desenvolvimento das plantas de arroz, aumenta a eficiência de absorção de nutrientes em relação ao suprimento isolado das duas formas de N.

    (conventional or intelligent) is possible to get more power generation than if we use the automatic methods based on feedback MW control. Consequently, the financial benefit due to the MW generated along a period of 2 months, is equivalent to return the investment required if the CCPP would had been repowered. Test also showed that with the fuzzy based SGC is possible to get a 'little more' power generation than if we use the PID based SGC. The development and implementation of the SGC was made in three phases: First Phase: Upgrading of the simulation dynamic mathematical model and implementation in a new software platform based on LabWindows/CVI. Second Phase: Design, implementation and testing of the PID based SGC. Third Phase: Design and implementation and testing of the Intelligent SGC, based in fuzzy logic.

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.

    Although leprosy involves the oral cavity in up to 60% of the patients, examination of the oral cavity in leprosy clinics or oral health science clinics is often neglected. Oral involvement in leprosy can broadly be divided into non-specific and specific lesions. In this review, we discuss various oral manifestations in leprosy patients so as to increase the awareness about this aspect among dermatologists and dental surgeons.

    In this work a technical and economical analysis of the installation of a reverse osmosis desalting plant connected to a power station that uses the combined cycle technology under a co-generation scheme is presented: production of electricity and water. The operation program of the desalting power station will be determined by the demand of energy of the combined cycle power station; the proposal is that the desalting plant operates in the hours of low load of the power station and shuts down at the peak hours of electrical energy demand. So that this study is representative, the demand curves of electric energy of the units of combined cycle of Central President Juarez Rosarito of the Comision Federal de Electricidad (CFE) have been taken and updated the data of the reverse osmosis desalting plants that are available at the moment in the market. As basis of the study the level costs will be determined so much as the electrical energy generated by the power station of combined cycle, operating inside and outside of a co-generation scheme and the costs made level for the water produced by the reverse osmosis plant under two assumptions: the first one is buying the electrical energy from CFE and the second one considering that the CFE is the owner of the desalting plant and therefore the cost of electrical energy to desalting the plant is zero. This work shows the economic impacts on the costs of the generation of electrical energy and on those of the desalted water in a co-generation scheme. The results shown in this study can be considered for the future planning in the construction of desalting plants to supply of water in the Northwestern zones of the country where serious problems of water shortage exist.

    Full Text Available Foi monitorado o impacto do tratamento combinado de lixiviado e esgoto doméstico de uma estação de tratamento operando em escala piloto por processo de lodos ativados, sobre peixes do gênero Tilapia: Biomarcadores de toxicidade (concentração de metalotioneínas, atividade da acetilcolinesterase, metábolitos de HPA e presença de micronúcleos foram utilizados na avaliação dos riscos de danos aos organismos aquáticos devido à interação com poluentes contidos nos efluentes pós-tratamento. A concentração de metalotioneínas não apresentou variação significativa entre os grupos expostos e de controle. A atividade da enzima acetilcolinesterase foi inibida em apenas um dos grupos expostos, indicando possível presença de agentes inibidores no efluente tratado. A avaliação dos metabólitos dos HPA naftaleno, pireno, benzo(apireno e 1-hidroxipireno sinalizou a provável presença desses compostos em ao menos um dos afluentes do tratamento combinado. As frequências de micronúcleos e outras anormalidade nucleares eritrocitárias também apontam para maior incidência de danos genotóxicos em células dos organismos expostos do que nos controles. O uso de biomarcadores mostrou-se importante para possibilitar uma avaliação de danos subletais presentes em organismos expostos à fonte de poluição estudada.

    This document proposes a methodology that reunites support tools for the operator of a Combined Cycle Generating Power Station allowing him to identify and to classify gas turbine faults, it also reunites some tools for the generation of action advices in the decision making on the operation maneuvers necessary to counteract the effects caused by faults. We are talking about a system implemented in a power station with the reconfiguration of processes and fault arrangement capacities. For this purpose, the line of exhibition delimits first the existing knowledge on automatic control and operations supervision systems in a CCPP and immediately emphasizes the cracks of the system to let pass to the fault tolerant active control system that will detect faults of the gas and steam turbo-generators of a Combined Cycle Generating Power Plant.

Se trata principalmente de un sistema implantado en una central con las capacidades de re-configuracion de procesos y acomodo de fallas. Para esto, la linea de exposicion delimita primero el conocimiento existente sobre sistemas automaticos de control y supervision de operacion en una CGCC y resalta enseguida las grietas del sistema para darle paso al sistema de control activo tolerante a fallas que detectara fallas de los turbogeneradores de gas y vapor de una Central Generadora de Electricidad de Ciclo Combinado.

  3. 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.

    Full Text Available BACKGROUND: A possible increase in the incidence of venous thromboembolic events has been reported among users of third generation oral contraceptives. The objective of this study was to evaluate the effect of a low dose oral contraceptive (15 µg ethinyl estradiol/60 µg gestodene on the venous endothelial function of healthy young women. METHODS: Prospective case control study using the dorsal hand vein technique. Venous endothelial function was evaluated at baseline and after 4 months in the oral contraceptive users group (11 women and in a control group (9 women. After preconstriction of the vein with phenylephrine, dose-response curves for acetylcholine and sodium nitroprusside were constructed. RESULTS: In the contraceptive users group, a reduction occurred in the maximum venodilation response to acetylcholine and sodium nitroprusside after 4 months of oral contraceptive use, but this difference was not statistically significant (P > 0.05. No significant changes were detected in maximum venodilation responses to acetylcholine and sodium nitroprusside at the 4-month time point in the control group. CONCLUSION: This study found no significant impairment of endothelium-dependent or independent venodilation in healthy young women following oral contraceptive use. Further studies are necessary using the same methodology in a larger sample over a longer follow-up period.Um aumento no risco de tromboembolismo venoso têm sido descrito em usuárias de anticoncepcionais hormonais oral de terceira geração.

Radiation-induced oral mucositis affects the quality of life of the patients and the family concerned. The present day management of oral mucositis is mostly palliative and or supportive care. The newer guidelines are suggesting Palifermin, which is the first active mucositis drug as well as Amifostine, for radiation protection and cryotherapy. The current management should focus more on palliative measures, such as pain management, nutritional support, and maintenance, of good oral hygiene

    Although it had been shown as early as 1968 that oral rehydration therapy was as effective as intravenous rehydration therapy in the treatment of dehydration due to diarrhoea, use of oral rehydration therapy was limited to rural health centres. In large urban hospitals oral rehydration therapy was held to be inferior to intravenous therapy and tended to be used only when the latter was not available. The results reported in the article by Samadi et al. in 1983 were extremely important in help...

    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...

    Determining the bacterial composition of the canine oral microbiome is of interest for two primary reasons. First, while the human oral microbiome has been well studied using molecular techniques, the oral microbiomes of other mammals have not been studied in equal depth using culture independent methods. This study allows a comparison of the number of bacterial taxa, based on 16S rRNA-gene sequence comparison, shared between humans and dogs, two divergent mammalian species. Second, canine or...

    Cancer is now the leading cause of death in Japan. A rapid increase in cancer mortality is expected as Japan is facing a super-aged society. Many causes of cancer are known to be closely linked to life style factors, such as smoking, drinking, and diet. The oral environment is known to be involved in the pathogenesis and development of various diseases such as bronchitis, pneumonia, diabetes, heart disease, and dementia. Because the oral cavity acts as the bodily entrance for air and food, it is constantly exposed to foreign substances, including bacteria and viruses. A large number of bacteria are endemic to the oral cavity, and indigenous oral flora act to prevent the settlement of foreign bacteria. The oral environment is influenced by local factors, including dental plaque, tartar, teeth alignment, occlusion, an incompatible prosthesis, and bad lifestyle habits, and systemic factors, including smoking, consumption of alcohol, irregular lifestyle and eating habits, obesity, stress, hormones, and heredity. It has recently been revealed that the oral environment is associated with cancer. In particular, commensal bacteria in the oral cavity are involved in the development of cancer. Moreover, Candida, human papilloma virus and Epstein-Barr virus as well as commensal bacteria have been reported to be associated with the pathogenesis of cancer. In this review, we introduce recent findings of the correlation between the oral environment and cancer. PMID:27482300

    Full Text Available Introduction 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 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. Alterations of oral health during pregnancy Because of hormonal alterations there is an increased incidence of dental diseases: gingivitis and low salivary pH (inflammation and bleeding gums. Impact of nutrition during pregnancy on oral health 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.

    Full Text Available Oral sex is commonly practiced by sexually active couples of various age groups, including male-female and same-gender adolescents. The various type of oral sex practices are fellatio, cunnilingus, and analingus. Oral sex can transmit oral, respiratory, and genital infections from one site in body to the other. Oral health has a direct correlation on the transmission of infection; a cut in the mouth, bleeding gums, lip sores or broken skin increases chances of life-threatening infections. Although oral sex is considered a low risk activity, it is important to use protection such as physical barriers, health and medical issues, ethical issues, and oral hygiene and dental issues. The ulcerations or unhealthy periodontium in mouth 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.

  10. 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.

The study has indicated that this rise is associated with regional population growth due to the forced migrants after the collapse of the USSR. Financial problems, unbalanced nutrition, poor oral hygiene, and depression in this group of patients have contributed to the higher incidence of precancers and cancers.

  13. Oral and systemic photoprotection.

    Photoprotection can be provided not only by ultraviolet (UV) blockers but also by oral substances. Epidemiologically identified associations between foods and skin cancer and interventional experiments have discovered mechanisms of UV skin damage. These approaches have identified oral substances that are photoprotective in humans. UV inhibits adenosine triphosphate (ATP) production causing an energy crisis, which prevents optimal skin immunity and DNA repair. Enhancing ATP production with oral nicotinamide protects from UV immunosuppression, enhances DNA repair and reduces skin cancer in humans. Reactive oxygen species also contribute to photodamage. Nontoxic substances consumed in the diet, or available as oral supplements, can protect the skin by multiple potential mechanisms. These substances include polyphenols in fruit, vegetables, wine, tea and caffeine-containing foods. UV-induced prostaglandin E2 (PGE2 ) contributes to photodamage. Nonsteroidal anti-inflammatory drugs and food substances reduce production of this lipid mediator. Fish oils are photoprotective, at least partially by reducing PGE2 . Orally consumed substances, either in the diet or as supplements, can influence cutaneous responses to UV. A current research goal is to develop an oral supplement that could be used in conjunction with other sun protective strategies in order to provide improved protection from sunlight. PMID:24313740

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.

    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.

    Divers can have several oral problems. Firstly, problems caused by pressure changes. These are barodontalgia and odontocrexis. Barodontalgia is toothache by barotrauma. Odontocrexis is restorations coming lose or breaking or tooth fractures by expansion of air beneath restorations. Other problems can occur by cements used to fix casted restorations, by inflammations in the orofacial region, and by not yet fully healed oral wounds. Secondly, there are problems related to the diver's mouthpiece. To keep the mouthpiece in place, the mandible has to be forced in a forward position. Holding this position often and for long periods of time, may develop or aggravate temporomandibular dysfunction. Insufficient fit of the mouthpiece may induce oral mucosal lesions. Therefore, it is recommended to produce individual diver mouthpieces. It is also recommended to produce individual diver mouthpieces for complete dentures wearing divers and for divers with fixed orthodontic appliances. PMID:15932043

    Full Text Available Oral myiasis is a rare disease caused by larvae of dipteran flies. Houseflies are strongly suspected of transmitting at least 65 diseases to humans, including typhoid fever, dysentery and cholera. Flies regurgitate and excrete wherever they come to rest and thereby mechanically are the root cause for disease organisms. A case of oral myiasis caused by Chrysomya bezziana in the maxillary anterior region in a 40-year-old patient is presented. Manual removal of maggots, and surgical debridement of wound was done followed by broad-spectrum anti-parasitic medications. A note on the identification of the larva and histopathology of the tissue is also highlighted here.

    Objetivos. Examiné los efectos combinados del acceso a la atención primaria mediante el Programa de Salud Familiar (PSF) y las transferencias condicionadas de dinero en efectivo del Programa Bolsa Familia (PBF) sobre la mortalidad infantil posneonatal (MIPN) en Brasil. Métodos. Empleé un análisis ecológico longitudinal usando datos en panel de 4 583 municipios brasileños de 1998 al 2010, con 54 253 observaciones en total. Estimé modelos de regresión de efectos fijos por mínimos cuadrados ordinarios, con la tasa de MIPN como la variable dependiente y el PSF, el PBF y sus interacciones como las principales variables independientes de interés. Resultados. La asociación de una mayor cobertura del PSF con una menor tasa de MIPN se volvió más fuerte conforme aumentaba la cobertura del PBF. En los promedios de todas las demás variables, cuando la cobertura de PBF era 25%, la MIPN predicha fue 5,24 (intervalo de confianza [IC] de 95% = 4,95, 5,53) para una cobertura del PSF de 0%, y de 3,54 (IC de 95% = 2,77, 4,31) para una cobertura del PSF de 100%. Cuando la cobertura del PBF era de 60%, la MIPN predicha fue 4,65 (IC de 95% = 4,36, 4,94) para una cobertura del PSF de 0%, y de 1,38 (IC de 95% = 0,88, 1,89) para una cobertura del PSF de 100%. Conclusiones. El efecto del PSF depende de la ampliación del PBF. Para las poblaciones empobrecidas y subatendidas, la combinación de intervenciones tanto del lado de la oferta como del lado de la demanda podría ser necesaria para mejorar los resultados en salud.

    Full Text Available La paracoccidioidomicosis (PCM o blastomicosis suramericana es la micosis sistémica más importante de América latina que es relativamente común en Brasil, Venezuela, Colombia, Ecuador y Argentina. Los casos esporádicos también pueden verse en algunos otros países, la cual es progresiva y con un infrecuente desenlace fatal si no es tratada a tiempo. Se considera como una enfermedad multifocal, con lesiones orales como la característica prominente. Es causada por un hongo dimórfico, Paracoccidioides brasiliensis, que afecta principalmente la piel, los ganglios linfáticos, los pulmones y membranas mucosas oral, nasal y gastrointestinal. Dependiendo de la inmunidad específica del huésped, la infección puede asumir muchas formas y afecta a uno o varios órganos, llegando a ser una enfermedad grave y potencialmente fatal. Es muy importante para los profesionales de la salud de todo el mundo tener conocimiento acerca de la Paracoccidioidomicosis porque a veces la enfermedad sólo se manifiesta muchos años después de que haya abandonado la zona endémica. Para proporcionar información útil sobre el diagnóstico y tratamiento de la enfermedad se presenta caso clínico de un paciente masculino de 48 años de edad procedente de una zona rural de Juramento Brasil, por presentar múltiples úlceras dolorosas en encía y paladar de 3 meses de evolución; refiere antecedentes de fumador crónico, al examen clínico extraoral se descartan lesiones en otros órganos y al examen intraoral se observan múltiples úlceras con fondo necrótico y granulomatoso localizadas en encía y paladar. Se realizó una biopsia incisional de la lesión y el material fue enviado para estudio anatomopatológico. El informe histopatológico confirmó la impresión clínica de Paracoccidioidomicosis.

    of the computation, the programming languages and the numerical methods allow to develop mathematical models that simulate in an approximate manner the processes to control, as it is the case of the combined cycle thermoelectric power station and in this way making the evaluation of algorithms of modern control possible. In chapter I a functional description of the steam turbine process is given. Since this belongs to a combined cycle thermoelectric power station, it is begun with the description of this power station, later to emphasize the subsystem of the steam turbine and emphasize each one of the elements that comprise this last one. [Espanol] Este trabajo de investigacion esta orientado a disenar, desarrollar y validar un algoritmo de control moderno, que permita la obtencion de mejores desempenos en el control de velocidad de una turbina de vapor perteneciente a una central termoelectrica de ciclo combinado, en todo el intervalo de operacion, asi como la obtencion de mejores desempenos en el control de la cantidad de megawatts generados por la misma cuando esta acoplada a un generador electrico, comparando el desempeno con el obtenido mediante el controlador convencional existente. Los cambios en la referencia de velocidad o carga, son a solicitud del operador y se dan siempre en forma de rampa, indicando la rapidez con la que se desea efectuar el cambio de valor en la referencia.

    Full Text Available El síndrome de ovario poliquístico es una de las patologías mas relacionadas con la infertilidad femenina en nuestro medio además de todos sus efectos secundarios sobre el estado físico, emocional y social de la paciente, por lo que un diagnóstico temprano y un tratamiento adecuado le permite a la paciente disfrutar de una vida normal. En la actualidad se conoce bien que el tratamiento de primera elección son los anticonceptivos orales combinados, pero también hay que tratar muchos de los efectos adversos de este síndrome por lo que un cambio en el estilo vida y otras terapias adjuntas como el uso de la metformina se utilizan mucho actualmente, dejando realmente como un último recurso pero no menos importante a la cirugía.The poliquistic ovaric syndrome are one of the most sigmificants patologys related about female infertility in our enviroment, plus all the adversary efects over the physical emotional and social state of the patient, thats why a early diagnogsis an a achived treatment let the patient development a normal live.

  17. History of oral contraception.

    Dhont, Marc

    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. PMID:21091163

    Buxner, Sanlyn; Holbrook, Jarita; AAS Oral History Team

    2016-06-01

    Now in its fourth year, the AAS Oral History Project has interviewed over 80 astronomers from all over the world. Led by the AAS Historical Astronomy Division (HAD) and partially funded by the American Institute of Physics Niels Bohr Library and ongoing support from the AAS, volunteers have collected oral histories from astronomers at professional meetings starting in 2015, including AAS, DPS, and the IAU general assembly. Each interview lasts one and a half to two hours and focuses on interviewees’ personal and professional lives. Questions include those about one’s family, childhood, strong influences on one’s scientific career, career path, successes and challenges, perspectives on how astronomy is changing as a field, and advice to the next generation. Each interview is audio recorded and transcribed, the content of which is checked with each interviewee. Once complete, interview transcripts are posted online as part of a larger oral history library at https://www.aip.org/history-programs/niels-bohr-library/oral-histories. Future analysis will reveal a rich story of astronomers and will help the community address issues of diversity, controversies, and the changing landscape of science. We are still recruiting individuals to be interviewed from all stages of career from undergraduate students to retired and emeritus astronomers. Contact Jarita Holbrook to schedule an interview or to find out more information about the project (astroholbrook@gmail.com). Also, contact Jarita Holbrook if you would like to become an interviewer for the project.

    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.

    2015-01-01

    Full Text Available Background: Vitiligo is one of the disorder that has social impact . Both skin and mucous membrane show depigmentation in vitiligo. Depigmentation in oral cavity can be more easily observed and the patient can be given awareness regarding the condition if they are unaware of vitiligo elsewhere in their body and can be guided for treatment. Aim and objectives: The aim of this study is to determine the frequency of occurrence of oral mucosal vitiligo in vitiligo patients and to determine the most commonly involved oral mucosal site. Materials and methods: The study sample included 100 vitiligo patients. The patients of all age groups and both genders were included. Vitiligo patients associated with systemic conditions such as thyroid disorders, juvenile diabetes mellitus, pernicious anemia, Addison′s disease were excluded in this study. Results: Out of 100 vitiligo patients 44 % male and 56% were female. The oral presentation of vitiligo in this study showed depigmentation of buccal mucosa in 5% of patients, labial mucosa in 5% of patients, palate in 8% of patients, gingiva in 2% of patients and alveolar mucosa 1% . Depigmentation of lip was seen in 42% of patients. Lip involvement refers to depigmentation of both the lips or either lip. Also vermilion border involvement was noted in majority of cases. In some cases, the depigmentation of lip extended to the facial skin also. Conclusion: In this study 55 patients out of 100 patients showed depigmentation in the oral cavity. Lip involvement was most common in this study showing about 42% of patients. Intraoral mucosal involvement was found in 21% of patients. Among intraoral mucosal site palate was common followed by buccal and labial mucosa, gingiva. Two patients had lip pigmentation as the only manifestation without any depigmentation in the skin.

  10. Social disparity and oral health

    Directory of Open Access Journals (Sweden)

    Maria Fidela de Lima Navarro

    2012-01-01

    Full Text Available There is a clear reported association between social disparity and oral health, for example, between dental caries and malnutrition in children. This fact is detected in several studies, and also found amongst the Brazilian population. However, several efforts have been made to improve the quality of life of the population and to achieve the 2015 Millennium Development Goals. Oral health is a branch to be improved among these goals. The Brazilian experience has been drawing the attention of authorities, insofar as there have been direct improvements in oral health through state oral health programs, and also indirect results by improving the quality of life of the population. Included within the Brazilian oral health programs are the Family Health Program and Smiling Brazil Program. The former is a global healthcare program which involves primary oral healthcare, while the latter is a specialized oral care program. Among the social programs that would indirectly improve oral health are Family Stipend and the Edmond and Lily Safra International Institute of Neuroscience of Natal (ELS-IINN. In conclusion, although oral health problems are related to socioeconomic factors, the implementation of primary oral health programs and programs to improve the population's quality of life may directly or indirectly improve the oral health scenario. This fact is being observed in Brazil, where the oral health policies have changed, and social programs have been implemented.

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. PMID:27352462

    2011-01-01

    Oral health includes freedom from disease in the gums, the mucosa and the teeth. There has been a striking reduction in dental caries and periodontitis in industrialized countries, although the proportion with severe disease has remained at 10-15%, and the prevalence increases in less developed countries. If left untreated, these diseases may lead to pain, and impaired quality of life and nutritional status. Prevention and treatment need, besides traditional implementation of proper oral hygiene, sugar restriction and use of fluoride, newer cost-effective strategies. Non-sweetened dairy products, which are proven non-cariogenic, or specific bioactive components from alike sources might prove to be part of such strategies. Thus, milk proteins, such as bovine and human caseins and lactoferrin, inhibit initial attachment of cariogenic mutans streptococci to hydroxyapatite coated with saliva or purified saliva host ligands. In contrast, both bovine and human milk coated on hydroxyapatite promotes attachment of commensal Actinomyces naeslundii and other streptococci in vitro, and phosphorylated milk-derived peptides promote maintenance of tooth minerals, as shown for the β-casein-derived caseino-phosphate peptide. Observational studies are promising, but randomized clinical trials are needed to reveal if dairy products could be a complementary treatment for oral health. PMID:21335990

  5. Antibiotics and oral contraceptives.

    Rubin, D F

    1981-04-01

    Dermatologists often prescribe oral tetracycline for the control of acne, primarily, and to a much lesser extent, for the treatment of cutaneous infections. A number of the patients taking tetracycline are also taking birth control pills. A recent article in the British Medical Journal (1980;1:293) indicates that this combination can lead to a failure of the (OC) oral contraceptive. Such failure had been associated with ampicillin as well. It is believed that the mechanism for this was the disturbance in normal gut flora, with consequent effects on bacterial hydrolysis of steroid conjugates. This would interrupt the enterohepatic circulation of contraceptive steroids, resulting in a less than normal concentration of circulating steroids. It was recommended that women taking low-dose OCs take extra precautions against pregnancy during any cycle in which antibiotics are given. In regard to our care of and responsibilities to our patients, and in an era when malpractice suits for all types of reasons are more common, it certainly behooves dermatologists to recognize and be concerned about this potential consequence of prescribing oral antibiotics.

    Full Text Available Introduction: Lymphangioma is a change of lymphatic vessels that frequently affects the head and neck region. Its occurrence at oral cavity is rare and it is most commonly identified at the anterior two-thirds of the tongue. At this location, it is clinically characterized as transparent and generally grouped vesicles, which can be red or purple. The deep lesions appear as nodular masses of variable color and superficial texture. It can be classified according to the size of vessels into three types: capillary, cavernous, and cystic lymphangioma. Several types of treatment have been suggested; and the most commonly used treatments are: surgical excision, application of carbon dioxide laser, cryotherapy using liquid nitrogen, and sclerosing agents. Objective and case report: To describe a case of oral lymphangioma diagnosed in a 17-year-old female patient. The lesion was presented as multiple vesicles of soft consistency with thin epithelial lining and color ranging from translucent to yellow-reddish, involving the soft palate and the left retromolar region. Incisional biopsy confirmed the hypothesis of cavernous lymphangioma. Patient was followed-up for one year without signs of lesion relapse. Conclusion: Through this clinical case report and literature review, this study emphasizes the relevance of the clinical and histopathological features that should be considered to confirm the clinical hypothesis and indicate the proper therapeutic for oral lymphangiomas.

Para diferentes posiciones del centro de gravedad del conjunto semi-remolque-carga, se obtuvo las curvas que representan los movimientos característicos del vehículo en respuesta a la acción de una perturbación externa. Se calculó también, los factores de amortiguación para estos movimientos durante trayectorias curvas y rectas. Se estudió la influencia de la variación de la carga y del momento de inercia del semi-remolque para las diferentes posiciones del centro de gravedad adoptadas. Los resultados indican cambios significativos en la respuesta dinámica del vehículo con la variación de los parámetros de carga. Se determinó así las condiciones operacionales con menor margen de seguridad para que puedan ser evitadas por los usuarios. Se concluye que existen condiciones de carga que, aunque permitidas por la legislación vigente, deben ser evitadas.This work is about the directional stability of truck-semitrailer vehicle, commonly used in Brazil, as a function of load parameters. For different positions of centre of gravity of semi-trailer, the curves that represent the characteristic movements and the ratio of damping for these movements during curved and straight trajectories are obtained. The influence of load and moment inertia variations for different adopted positions of the centre of gravity of semi-trailer was calculated. The results show significant changes on dynamic response of vehicle with the variations of load parameters. Thus, the operating conditions with less safety margins were determined, so they can be avoided by users. The study allows concluding that there are load conditions that although being accepted by the present legislation, must be avoided.

    It has been formerly evaluated that it is possible to enhance notably the electric power generation in gas turbine power plants by cooling the air at the compressor inlet. It has been pointed out that provided a source of waste heat is available it can be very attractive the use of absorption refrigeration systems. In this paper the technical and the economical benefits of bringing the air inlet temperature down 8 Celsius degrees of the four gas turbines of the Combined Cycle Central of Tula, in the State of Hidalgo (combined cycle central-Tula) are evaluated. The results show that it is possible to achieve an efficiency enhancement of at least 1%, and that in very warm days up to 48 additional Megawatts can be generated, or about 10% of the installed capacity. The final economic result is very encouraging and an annual economical benefit in the order of 50 million pesos can be obtained and the refrigeration units can be amortized in approximately one year.

  11. Irradiation mucositis and oral flora

    International Nuclear Information System (INIS)

    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 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.

    Management of oral biofilms allows dentists to help control the pathogens responsible for periodontal disease and decay. Increasing evidence indicates that the oral system is a portal for pathogenic microorganisms. This is a cumulative situation with systemic effects that can overcome an individual's resistance threshold, culminating in systemic sequela. New evidence indicates that controlling these oral pathogens has systemic benefits, as oral pathology is related to cardiovascular and respiratory disease, diabetes, and systemic inflammatory responses, as well as low birth weight and pre-term deliveries. Some insurance companies now cover periodontal scaling for gingivitis and periodontal disease for pregnant women and patients at risk for pregnancy. PMID:17511362

    Oral jewelry is popular. One of the most widely spread types are so-called tooth diamonds made of composite materials which are applied to the teeth with an adhesive. Note that parents are required to sign a release form for under-aged patients in Switzerland. Tooth cap grills and gold teeth are considered status symbols within the Hip-Hop fashion scene. However, tooth ornaments favour the accumulation of plaque and can diminish the ability to articulate. With respect to jewelry in oral soft tissue especially tongue and lip piercings are of significance to dentists. Besides the systemic complications, which are mostly caused by a lack of hygiene or the failure of noting medical contraindications by the piercer, local complications occur frequently. After surgery, pain, swelling, infections as well as hemorrhages or hematomas can be observed. Long-term effects can be problematic: gingival recession can be discernes mainly in the case of lip piercings the loss of hard tooth substance in the case of tongue piercings. Because of that, conservation therapies can become indespensable. Patients wearing dental jewelry have to be aware of risks of tooth damage, and they regularly have to undergo dental check-ups. Information campaigns--for dentists as well as patients--are necessary. PMID:20112640

    The prevalence of prosthodontic treatment has been well recognized, and the need is continuously increasing with the ageing population. While the oral mucosa plays a critical role in the treatment outcome, the associated biomechanics is not yet fully understood. Using the literature available, this paper provides a critical review on four aspects of mucosal biomechanics, including static, dynamic, volumetric and interactive responses, which are interpreted by its elasticity, viscosity/permeability, apparent Poisson's ratio and friction coefficient, respectively. Both empirical studies and numerical models are analysed and compared to gain anatomical and physiological insights. Furthermore, the clinical applications of such biomechanical knowledge on the mucosa are explored to address some critical concerns, including stimuli for tissue remodelling (interstitial hydrostatic pressure), pressure–pain thresholds, tissue displaceability and residual bone resorption. Through this review, the state of the art in mucosal biomechanics and their clinical implications are discussed for future research interests, including clinical applications, computational modelling, design optimization and prosthetic fabrication.

No grupo Peridural, foi realizada anestesia peridural lombar contínua com ropivacaína a 0,5% 10 a 15 mL. No grupo Lombar, foi realizado bloqueio do plexo lombar pela via posterior com ropivacaína a 0,5% 0,4 mL.kg-1. Todos os pacientes foram submetidos à anestesia geral. Foram estudados: a dificuldade na execução dos bloqueios, sua eficácia e efeitos hemodinâmicos secundários. RESULTADOS: 41 pacientes foram incluídos no estudo. O tempo para execução do bloqueio peridural foi menor, mas o número de tentativas de posicionamento da agulha foi semelhante nos dois grupos. O bloqueio peridural foi mais eficaz. No grupo Lombar, houve aumento da pressão arterial diastólica e média (PAM e no duplo produto após a incisão e o consumo anestésico durante a operação foi maior. Após o bloqueio, a PAM foi menor nos momentos 50, 60 e 70 minutos após a realização do bloqueio peridural. O sangramento foi semelhante nos dois grupos. CONCLUSÕES: A técnica peridural promoveu bloqueio nociceptivo mais eficaz sem se associar à instabilidade hemodinâmica quando combinada à anestesia geral. O bloqueio do plexo lombar mostrou-se uma técnica útil em combinação com a anestesia geral quando a anestesia peridural estiver contraindicada.JUSTIFICATIVA Y OBJETIVOS: La anestesia para la artroplastia total de la cadera (ATC, constituye un reto a causa de la edad

    Full Text Available 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.

    Full Text Available Entre los sistemas de refrigeración movidos térmicamente asistidos por energía solar y gas natural, el sistema de refrigeración con eyector ha recibido especial atención. Este sistema se caracteriza por su simplicidad constructiva, ausencia de partes móviles, operación en bajas temperaturas y bajo costo operacional. Sin embargo, el ciclo de refrigeración por eyector tiene usualmente un bajo coeficiente de desempeño. Una alternativa de solución a este problema lo constituye el sistema de refrigeración con eyector combinado. La primera etapa está constituida por un ciclo de compresión mecánica de vapor convencional con R134a, mientras que la segunda etapa la constituye un ciclo termo-movido con eyector usando R141b como fluido de trabajo. Colectores de placa plana y un quemador de energía auxiliar entregan calor al ciclo de eyector. Este artículo describe la simulación en base horaria de un sistema de refrigeración combinado eyector-compresión de vapor asistido por energía solar y gas natural. El sistema de refrigeración solar combinado es modelado usando la herramienta de simulación TRNSYS-EES y los datos climáticos de un año típico de Florianópolis, Brasil. Los resultados obtenidos con la modelación computacional desarrollada para este sistema muestran la ventaja del ciclo de refrigeración combinado eyector-compresión de vapor por sobre el ciclo simple con eyector. Finalmente, el modelo computacional desarrollado en este artículo podría ser usado para realizar una optimización termo-económica del sistema en trabajos futuros.Among the thermally driven cooling systems assisted by solar energy and natural gas, the ejector cooling system has received special attention. This system is an interesting refrigeration technology due to its construction simplicity, absence of moving parts, operation at lower temperatures and a low operational cost.

    1980-01-01

    A laboratory study was undertaken with volunteer females (aged 20-25) to determine the effect of OCs (oral contraceptives) on hematologic and metabolic variables during exercise. 5 of the women studied were naturally cycling and 7 were taking OCs. The women worked at 2 workloads on a bicycle ergometer at 50% and 90% of their maximal aerobic capacity during 3 different phases of their menstrual cycle. There was no better time of the month for doing the 50% or the 90% workload in either group. Heartrate for the OC group was significantly higher at the 50% maximal capacity. Results of the test indicate tha women on OCs have somewhat reduced cardiac efficiency and are ventilating more to carry out a given amount of work when compared to women who are naturally cycling. Possible explanations for the higher heart rate are put forward. The main limitation of the study is that the subject numbers involved are small and the number of cycles studied is also small.

  19. As-yet-uncultivated oral bacteria: breadth and association with oral and extra-oral diseases

    Directory of Open Access Journals (Sweden)

    José F. Siqueira

    2013-05-01

    Full Text Available It has been shown that 40–60% of the bacteria found in different healthy and diseased oral sites still remain to be grown in vitro, phenotypically characterized, and formally named as species. The possibility exists that these as-yet-uncultivated bacteria play important ecological roles in oral bacterial communities and may participate in the pathogenesis of several oral infectious diseases. There is also a potential for these as-yet-uncultivated oral bacteria to take part in extra-oral infections. For a comprehensive characterization of physiological and pathogenic properties as well as antimicrobial susceptibility of individual bacterial species, strains need to be grown in pure culture. Advances in culturing techniques have allowed the cultivation of several oral bacterial taxa only previously known by a 16S rRNA gene sequence signature, and novel species have been proposed. There is a growing need for developing improved methods to cultivate and characterize the as-yet-uncultivated portion of the oral microbiome so as to unravel its role in health and disease.

    Multiple sclerosis (MS) is a complex autoimmune disease of the central nervous system. Disease-modifying drugs licensed for MS treatment have been developed to reduce relapse rates and halt disease progression. The majority of current MS drugs involve regular, parenteral administration, affecting long-term adherence and thus reducing treatment efficacy. Over the last two decades great progress has been made towards developing new MS therapies with different modes of action and biologic effects. In particular, oral drugs have generated much interest because of their convenience and positive impact on medication adherence. Fingolimod was the first launched oral treatment for relapsing-remitting MS; recently, Teriflunomide and Dimethyl fumarate have also been approved as oral disease-modifying agents. In this review, we summarize and discuss the history, pharmacodynamics, efficacy, and safety of oral agents that have been approved or are under development for the selective treatment of MS.

    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

    2013-06-01

    Full Text Available OBJECTIVES: Oral mucositis is a complication frequently associated with hematopoietic stem cell transplantation, decreasing a patient's quality of life and increasing the occurrence of opportunistic infections. The purpose of this study was to determine the incidence and severity of oral mucositis and to assess the correlation of this disease with the oral health of an individual at the time of hematopoietic stem cell transplantation. METHODS: Before transplantation, patients' oral health and inflammatory conditions were determined using the gingival index and the plaque index, which are based on gingival bleeding and the presence of dental plaque, respectively. Additionally, the dental health status was determined using the decayed, missing, and filled teeth index. The monitoring of oral mucositis was based on the World Health Organization grading system and was performed for five periods: from Day 0 to D+5, from D+6 to D+10, from D+11 to D+15, from D+16 to D+20, and from D+21 to D+30. RESULTS: A total of 97 patients (56% male and 44% female who underwent hematopoietic stem cell transplantation at the Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo between January 2008 and July 2009 were prospectively examined. The incidence of ulcerative mucositis was highest from days +6 to +10 and from days +11 to +15 in the patients who underwent autologous and allogeneic hematopoietic stem cell transplantation, respectively. CONCLUSION: The data, including the dental plaque and periodontal status data, showed that these oral health factors were predictive of the incidence and severity of oral mucositis in a cohort of patients with similar conditioning regimens before hematopoietic stem cell transplantation.

Oral precancer is a intermediate state with increased cancer rate which can be recognized and treated obviously with much better prognosis than a full blown malignancy. Oral cancer risk can be lowered or even prevented by simply understanding basic oral hygiene, different bacteria found in the mouth, and how diet influences oral cancers. Currently, researc...

    Oral cancer is one of the major global threats to public health. Oral cancer development is a tobacco-related multistep and multifocal process involving field cancerization and carcinogenesis. The rationale for molecular-targeted prevention of oral cancer is promising. Biomarkers of genomic instability, including aneuploidy and allelic imbalance, are able to measure the cancer risk of oral premalignancies. Understanding of the biology of oral carcinogenesis will give us important advances for...

    extra space and expenses implied in the use of repeated devices. The design of the system was carried out by using the structural analysis (SA) which is a tool based on graph theory and computer science. The SA allowed the analysis of monitorability, detectability and isolability properties of the process, besides it provides the computation sequence of non monitored (unknown) variables in order to obtain the analytical redundancy relations. To validate the fault diagnosis system, the detection and isolation algorithms were programmed in C language and integrated to the simulator software of a CCPP in LabWindows CVI. In order to provide a way to easily identify the existence of a fault, a graphic interface was developed, where the faulty component, sensor or actuator is indicated. [Spanish] Debido a la naturaleza fisica de sus componentes, todos los procesos tecnologicos son susceptibles de falla. Estas fallas afectan el funcionamiento del sistema, provocando desde una reduccion en su desempeno hasta cuantiosas perdidas economicas y en el peor de los casos desastres ambientales y humanos. La deteccion oportuna de la presencia de las fallas ayuda a tomar acciones correctivas y como consecuencia a reducir el dano potencial que estas ocasionan. Para realizar la tarea de deteccion de fallas, los procesos tecnologicos cuentan con sistemas de monitoreo y alarmas que se activan si algunas de las variables monitoreadas rebasa un umbral establecidos. El metodo presenta el inconveniente de que ante la presencia de una sola falla se pueden activar varias alarmas, lo que dificulta la tarea para localizar al elemento danado. Ademas, se basa en la redundancia fisica, que consiste en el uso de elementos repetidos para realizar una misma tarea. Las centrales de generacion de ciclo combinado (CGCC) son procesos de gran escala con alto grado de susceptibilidad a fallas, a causa de las condiciones estrictas en las que operan y del gran numero de componentes que contienen, incluyendo

    Aphthous ulcers are painful ulcerations located on the mucous membrane, generally in the mouth, less often in the genital area. Three clinical forms of aphthous ulcers have been described: minor aphthous ulcers, herpetiform aphthous ulcers and major aphthous ulcers. Many other conditions presenting with oral bullous or vesiculous lesions orulcerations and erosions can be mistaken for aphthous ulcers. Currently, treatment of aphthous ulcers is palliative and symptomatic. Topical treatments (topical anesthetics, topical steroids and sucralfate) are the first line therapy. Recurrent aphthous stomatitis (RAS) is defined by the recurrence of oral aphthous ulcers at least 4 times per year. RAS is often idiopathic but can be associated with gastro-intestinal diseases (i.e. celiac disease, inflammatory bowel diseases), nutritional deficiencies (iron, folates…), immune disorders (HIV infection, neutropenia) and rare syndromes. Behçet's disease is a chronic, inflammatory, disease whose main clinical feature is recurrent bipolar aphthosis. Colchicine associated with topical treatments constitutes a suitable treatment of most RAS. Thalidomide is the most effective treatment of RAS but its use is limited by frequent adverse effects. Oral ulcers can be related to a wide range of conditions that constitute the differential diagnoses of aphthous ulcers. Oral ulcers are classified into three main groups: acute ulcers with abrupt onset and short duration, recurrent ulcers (mainly due to postherpetic erythema multiforme) and chronic ulcers (with slow onset and insidious progression). Acute oral ulcers are due to trauma, bacterial infections (including acute necrotizing ulcerative gingivitis), deep fungal infection, gastro-intestinal (namely inflammatory bowel disease) or systemic diseases. Chronic oral ulcers may be drug-induced, or due to benign or malignant tumors. Every oral solitary chronic ulcer should be biopsied to rule out squamous cell carcinoma. A solitary palatal ulcer

    Science.gov (United States)

    1978-01-01

    This discussion of oral contraceptives (OCs) presents information on the following: types of steroidal contraception OCs, injectable contraceptive agents, implants, intravaginal rings, IUD bearing steroids, male pills, intracervical devices, contraceptive bracelets, and intranasal administration of hormones); guidelines for adolescent usage (why adolescents use OCs, common medical concerns, assessment, prescribing, educating for user effectiveness, and the length of time that the adolescent can use OCs); the marketing of OCs; attitudes toward OCs; the effect of OCs on insulin requirements in diabetes; mortality among OC users; assessing new knowledge of mortality trends and OCs; beneficial and adverse effects; sexual and psychological response to OCs; chromosomal abnormalities and OCs; ectopic pregnancies and the progestogen only pill; liver tumors and OCs; cancer and OCs; eye conditions and OCs; and postpill amenorrhea and infertility. Most adolescents choose OCs as their initial contraceptive method because it is probably the only method of which they have much knowledge. Most adolescents lack the needed level of sexual maturity and sexual sophistication to pause to insert a diaphrage or to use a condom. Another attraction of OCs is reliability. At this time 12 major companies based in 8 countries (excluding China) produce and market OCs. Basically either of 2 estrogens, ethinyl estradiol and mestranol, are used in combination with about 6 different progestogens. Attitudes vary greatly and range from total acceptance to total rejection. Despite some negative views about OC, 32.2% of Australian women in childbearing years are using OCs indicating a high degree of acceptance. The new data available indicate strongly that the hazards of using OCs are somewhat greater than previously suspected. In 1977 the Royal College of General Practitioners reported a death rate from circulatory disease which was in OC users 4.7 times that of women who had never used OCs. The

    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. PMID:26632800

    The predominant diet fed to captive carnivores in North America consists of ground meat formulated to provide full nutritional requirements. However, this ground meat diet completely lacks the mechanical properties (i.e., toughness and hardness) of the foods these animals would consume in the wild. The goal of this study is to evaluate the effect of captivity on oral health by comparing the prevalence of periodontal disease and dental calculus accumulation in wild and captive lions and tigers (Panthera leo and Panthera tigris), and to also correlate oral health with cranial morphology in these specimens. To achieve this, 34 adult lion and 29 adult tiger skulls were scored for the presence and extent of dental calculus and periodontal disease. These oral health scores were also compared to cranial deformations examined in a previous study. We found that the occurrence and severity of calculus buildup and periodontal disease was significantly higher in captive felids compared to their wild counterparts. Further, higher calculus accumulation occurred on the posterior teeth when compared to the anterior teeth, while an opposite trend for periodontal disease was observed. We also found a significant correlation between oral health and cranial morphology of lions and tigers. The results suggest that food mechanical properties are significant factors contributing to oral health in felids. PMID:27473998

  13. Oral manifestations of acute leukaemia

    Ivanović Mirjana

    2011-01-01

    Full Text Available Acute leukaemia is the most common form of chilhood cancer. The aim of this paper was to underline the importance of oral manifestations in children with acute leukaemia. The disease and its treatment can directly or indirectly affect oral health. Oral manifestations are gingival inflammation and enlargement. Leukaemic cells are capable of infiltrating the gingiva and the deeper periodontal tissues which leads to ulceration and infection of oral tissues. Gingival bleeding is a common sign in patients with leukaemia. Symptoms include local lymphadenopathy, mucous membrane Petechiae and ecchymoses. Cytotoxic drugs have direct effects like mucositis, involving atrophy, desquamation and ulceration of the mucosa, with increasing the risk for local and systemic infections. Leukaemia can directly influence dental care and dental treatment, while oral lesions may have life-threatening consequences. Knowledge and skills among dentists may also not be adequate to treat children with acute leukaemia. It is therefore imperative that all stomatologists be aware of dental problems that occur in leukaemia in order to be able to effectively carry out appropriate measures to mitigate these problems.

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.

  15. Epigenetic Disregulation in Oral Cancer

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available Squamous cell carcinoma of the oral region (OSCC is one of the most common and highly aggressive malignancies worldwide, despite the fact that significant results have been achieved during the last decades in its detection, prevention and treatment. Although many efforts have been made to define the molecular signatures that identify the clinical outcome of oral cancers, OSCC still lacks reliable prognostic molecular markers. Scientific evidence indicates that transition from normal epithelium to pre-malignancy, and finally to oral carcinoma, depends on the accumulation of genetic and epigenetic alterations in a multistep process. Unlike genetic alterations, epigenetic changes are heritable and potentially reversible. The most common examples of such changes are DNA methylation, histone modification, and small non-coding RNAs. Although several epigenetic changes have been currently linked to OSCC initiation and progression, they have been only partially characterized. Over the last decade, it has been demonstrated that especially aberrant DNA methylation plays a critical role in oral cancer. The major goal of the present paper is to review the recent literature about the epigenetic modifications contribution in early and later phases of OSCC malignant transformation; in particular we point out the current evidence of epigenetic marks as novel markers for early diagnosis and prognosis as well as potential therapeutic targets in oral cancer.

    2013-01-01

      The usefulness of pronunciation teaching is a widely debated subject in the language teaching world. Some of the current research would suggest that teachers can make little or no difference in improving their students’pronunciation. In contrast, there is research that indicates that the teacher can make a noticeable difference if certain criteria, such as the teaching of suprasegmen⁃tals and the linking of pronunciation with oral practice, are fulfilled. This paper intends to address the practical challenges related to integrating pronunciation into oral communication. First, the central difficulty in integrating pronunciation into the speaking classroom is described. Next, all-skill principles to guide the incorporation of pronunciation into oral communication courses are suggested. Finally, possible implementation strategies that can be applied to a wide variety of instructional settings are explored.

    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.

    An oral drug delivery system using proteinoid microspheres is discussed with respect to its unique dependence on pH. It has been found that certain drugs such as insulin and heparin can be encapsulated in proteinoid spheres at stomach pH's (1-3). These spheres also dissemble at intestinal pH's (6-7) releasing the drug for absorption. Using this technique low molecular weight heparin and human growth hormone have been orally delivered successfully to several animal species. Future work has been proposed to study the interaction and binding of the specific drugs with synthesized oligopeptides.

    Oral malignant melanoma is a rare disease. The common sites of its occurrence are the palate and gingiva with the maxillary arch being affected 80% of the time. Because of their presence at relatively obscure areas in the oral cavity, most of the malignant melanomas of the oral cavity are diagnosed at a late stage. These lesions are associated with poor prognosis. The dental clinician must therefore carefully examine the head, neck, and oral cavity, and any pigmented lesion that may ex...

    Full Text Available Nutrition represents a summation of intake, absorption, storage and utilization of foods by the tissues. Oral tissues are one of the most sensitive indicators of nutritional state of the body. Nutritional deficiencies are associated with changes in the integrity (health and appearance of the oral structures/ tissues and these changes are frequently the first clinical signs of deficiency. Nutrition affects oral health and oral health affects nutrition. The effects of malnutrition can be seen in the oral structures in all stages of human growth and development from conception to old age. The consequence of certain oral diseases may compromise the nutrition by affecting the intake and mastication particularly in some vulnerable groups like people with severe caries, severe oral ulceration, advanced periodontal disease and the resulting edentulousness. The HIV pandemic has added another dimension to the issue of nutrition and oral health. Oral lesions are some of the earliest lesions seen in HIV/AIDS and 90% of HIV/AIDS patients will have oral lesions at a point in the course of the disease. These oral lesions are painful; disturb food intake and mastication thereby further compromising the nutrition of the affected individuals. In Africa, particularly the Sub-Saharan Africa, the burden of poverty, economic downturn and the HIV pandemic have added another dimension to the issue of food availability and nutrition. Malnutrition is a real problem in this area. This paper will examine the effects of compromised nutrition on oral health and the reverse.

    2015-04-01

    Primary mucosal leishmaniasis is a rare infectious disease, particularly in immunocompetent patients. We present a 50-year-old patient with a 6-week history of a painful lesion of the left buccal mucosa that mimicked cancer. The exophytic lesion looked invasive, and we took an incisional biopsy specimen to exclude cancer. The diagnosis of leishmaniasis was unexpected, and the patient was successfully treated with amphotericin B for five weeks. After five months the patient had a visceral recurrence. Chronic exophytic and ulcerated mucosal lesions that do not heal within 3-4 weeks should be regarded as the first signs of oral cancer, but primary oral leishmaniasis can easily mimic it.

    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. PMID:10518916

    2016-07-01

    Direct oral anticoagulants (DOAC) are recommended for stroke prevention in atrial fibrillation and for the treatment of venous thromboembolism. However, they are associated with hemorrhagic complications. Management of DOAC-induced bleeding remains challenging. Activated or non-activated prothrombin concentrates are proposed, although their efficacy to reverse DOAC is uncertain. Therapeutic options also include antidotes: idarucizumab, antidote for dabigatran, has been approved for use whereas andexanet alpha, antidote for anti-Xa agents, and aripazine, antidote for all DOAC, are under development. Other options include hemodialysis for the treatment of dabigatran-associated bleeding and administration of oral charcoal if recent DOAC ingestion. DOAC plasma concentration measurement is necessary to guide DOAC reversal. We propose an update on DOAC-associated bleeding, integrating the availability of dabigatran antidote and the critical place of DOAC concentration measurements. PMID:27297642

Results: Overall, only 48.9% of all patients showed awareness of oral cancer, with awareness especially poor among lower socioeconomic groups. Awareness of oral cancer risk factors and signs and symptoms did not vary significantly between men and women (P > 0.5; however, older participants (aged 40-64 years were more familiar with oral cancer signs than younger participants. More than half of all participants (56.8% were unaware of the common clinical presentations of oral cancer. Conclusions: The results of this survey showed knowledge regarding oral cancer to be quite low. Thus, educational programs are needed to increase public awareness about oral cancer, and dentists should request patients undergo examinations for oral cancer to ensure early detection.

    A human oral microbiota is the ecological community of commensal, symbiotic, and pathogenic microorganisms found in human oral cavity. Oral microbiota exists mostly in the form of a biofilm and maintains a dynamic ecological equilibrium with the host body. However, the disturbance of this ecological balance inevitably causes oral infectious diseases, such as dental caries, apical periodontitis, periodontal diseases, pericoronitis, and craniofacial bone osteomyelitis. Oral microbiota is also correlated with many systemic diseases, including cancer, diabetes mellitus, rheumatoid arthritis, cardiovascular diseases, and preterm birth. Hence, oral microbiota has been considered as a potential biomarker of human diseases. The "Human Microbiome Project" and other metagenomic projects worldwide have advanced our knowledge of the human oral microbiota. The integration of these metadata has been the frontier of oral microbiology to improve clinical translation. By reviewing recent progress on studies involving oral microbiota-related oral and systemic diseases, we aimed to propose the essential role of oral microbiota in the prediction of the onset, progression, and prognosis of oral and systemic diseases. An oral microbiota-based prediction model helps develop a new paradigm of personalized medicine and benefits the human health in the post-metagenomics era. PMID:27051943

    Malnutrition affects the oral health and a poor oral health in turn, may lead to malnutrition. This interdependent relationship sees good nutritional health, thus promoting good oral health and vice versa. Malnutrition may alter the homeostasis, which can lead to disease progression of the oral cavity, reduce the resistance to the microbial biofilm and reduce the capacity of tissue healing. It may even affect the development of the oral cavity. Protein-energy malnutrition occurs when there is a deficiency of protein, energy foods or both, which are relative to a body's need. Studies have suggested that enamel hypoplasia, salivary gland hypofunction and saliva compositional changes may be the mechanisms through which the malnutrition is associated with caries, while an altered eruption timing may create a challenge in the analysis of the age specific caries rates. This paper gives an insight on the relationship of the malnutrition and the protein-energy malnutrition with the oral health status. PMID:23449967

    Oral English has always been a major problem for Chinese Eng-lish as Second Language (ESL) students. In fact, most Chinese students do not practice oral English very often, while their reading and writing abilities have gained rapid progress. However, language is a system that includes both words and sounds for communicative use, neither of which can be neglected. While there are hundred forms of classroom activities, the usage of most effective o-ral activities has become a serious issue that an ESL teacher should focuses on. The review is based on research results on effective oral ESL activities. The research results on the factors should be considered when selecting/plan-ning oral activities and applying oral activities ESL classes.

    Oral lichen planus (OLP) and oral lichenoid reaction (OLR) are clinically and histopathologically similar diseases. Whereas OLP is a consequence of T cell mediated autoinflammatory process to a still unknown antigen, OLR might be caused by drugs, dental restorative materials and dental plaque. Pubmed was searched and 24 publications published over the last three years regarding etiology, diagnosis and malignant alteration were included in this study. Patients with OLR who have amalgam fillings near lesions should have them replaced, i.e. when possible they should be referred to patch test, as well as when drug-induced OLR are suspected. OLR lesions induced by drugs should disappear when the offending drug has been discontinued. Histology finding in OLR consists of more eosinophils, plasma cells and granulocytes in comparison to OLP lesions. Furthermore, OLP lesions showed more p53, bcl-2 and COX-2 positivity when compared to OLR. OLP is characterized by infiltration, atrophic epithelium, rete pegs and Max Joseph spaces, while deep infiltration into connective tissue and hyperkeratosis were the criteria for making the diagnosis of OLR. The number of degranulated mastocytes in the reticular layer, as well as the number of capillaries was higher in OLR in comparison to OLP. It seems that OLR are more prone to malignant alteration in comparison to OLP. PMID:27017728

    We report the results of an in-vitro study on autofluorescence from pathologically characterized normal and malignant squamous tissues from the oral cavity. The study involved biopsy samples from 47 patients with oral cancer of which 11 patients had cancer of tongue, 17 of buccal mucosa and 19 of alveolus. The results of excitation and emission spectroscopy at several wavelengths (280 nm less than or equal to (lambda) exless than or equal to 460 nm; 340 nm less than or equal to (lambda) em less than or equal to 520 nm) showed that at (lambda) ex equals 337 nm and 400 nm the mean value for the spectrally integrated fluorescence intensity [(Sigma) (lambda ) IF((lambda) )] from the normal tissue sites was about a factor of 2 larger than that from the malignant tissue sites. At other excitation wavelengths the difference in (Sigma) (lambda ) IF((lambda) ) was not statistically significant. Similarly, for (lambda) em equals 390 nm and 460 nm, the intensity of the 340 nm band of the excitation spectra from normal tissues was observed to be a factor of 2 larger than that from malignant tissues. Analysis of these results suggests that NADH concentration is higher in normal oral tissues compared to the malignant. This contrasts with our earlier observation of an reduced NADH concentration in normal sites of breast tissues vis a vis malignant sites. For the 337 nm excited emission spectra a 10-variable MVLR score (using (Sigma) (lambda ) IF((lambda) ) and normalized intensities at nine wavelengths as input parameters) provided a sensitivity and specificity of 95.7% and 93.1% over the sample size investigated.

    2016-02-01

    Food allergy is a potentially life-threatening condition with no approved therapies, apart from avoidance and injectable epinephrine for acute allergic reactions. Oral immunotherapy (OIT) is an experimental treatment in which food-allergic patients consume gradually increasing quantities of the food to increase their threshold for allergic reaction. This therapy carries significant risk of allergic reactions. The ability of OIT to desensitize patients to particular foods is well-documented, although the ability to induce tolerance has not been established. This review focuses on recent studies for the treatment of food allergies such as cow's milk, hen's egg, and peanut. PMID:26617227

    Full Text Available Osteosarcoma is the most common primary malignant mesenchymal tumor, accounting for approximately 20% of sarcomas, with 5% incidence in the jaws. They present various clinical and histological aspects as well as variable disease prognosis and outcome. About 50% of all osteosarcomas are osteoblastic, 25% fibroblastic, 25% chondroblastic. Metastasis of osteosarcoma in the oral cavity is rare, and very few cases have been described so far in the literature. This article presents a metastatic case of chondroblastic osteosarcoma in the mandibular right-attached gingiva arising from 4 th rib. This case report further suggests that chondroblastic osteosarcoma has poor prognosis.

    The ability to generate 3-dimensional volumetric images of the maxillofacial area has allowed surgeons to evaluate anatomy before surgery and plan for the placement of implants in ideal positions. However, the ability to transfer that information to surgical reality has been the most challenging part of implant dentistry. With the advent of computer-assisted surgery, the surgeon may now navigate through the entire implant procedure with extremely high accuracy. A new portable laptop navigated system for oral implantology is discussed as an adjunct for complex implant cases. PMID:16569960

    2012-11-01

    Full Text Available Abstract Background Oral clefts are one of the most common birth defects with significant medical, psychosocial, and economic ramifications. Oral clefts have a complex etiology with genetic and environmental risk factors. There are suggestive results for decreased risks of cleft occurrence and recurrence with folic acid supplements taken at preconception and during pregnancy with a stronger evidence for higher than lower doses in preventing recurrence. Yet previous studies have suffered from considerable design limitations particularly non-randomization into treatment. There is also well-documented effectiveness for folic acid in preventing neural tube defect occurrence at 0.4 mg and recurrence with 4 mg. Given the substantial burden of clefting on the individual and the family and the supportive data for the effectiveness of folic acid supplementation as well as its low cost, a randomized clinical trial of the effectiveness of high versus low dose folic acid for prevention of cleft recurrence is warranted. Methods/design This study will assess the effect of 4 mg and 0.4 mg doses of folic acid, taken on a daily basis during preconception and up to 3 months of pregnancy by women who are at risk of having a child with nonsyndromic cleft lip with/without palate (NSCL/P, on the recurrence of NSCL/P. The total sample will include about 6,000 women (that either have NSCL/P or that have at least one child with NSCL/P randomly assigned to the 4 mg and the 0.4 mg folic acid study groups. The study will also compare the recurrence rates of NSCL/P in the total sample of subjects, as well as the two study groups (4mg, 0.4 mg to that of a historical control group. The study has been approved by IRBs (ethics committees of all involved sites. Results will be disseminated through publications and presentations at scientific meetings. Discussion The costs related to oral clefts are high, including long term psychological and socio-economic effects. This study

    Oral health care in patients undergoing chemotherapy and/or radiation therapy can be complex. Care delivered by a multidisciplinary approach is timely and streamlines the allocation of resources to provide prompt care and to attain favorable outcomes. A hospital dentist, oral and maxillofacial surgeon, and a maxillofacial prosthodontist must be involved early to prevent avoidable oral complications. Prevention and thorough preparation are vital before the start of chemotherapy and radiation therapy. Oral complications must be addressed immediately and, even with the best management, can cause delays and interruption in treatment, with serious consequences for the outcome and prognosis.

    2016-01-01

    Introduction The management of oral mucositis is a challenge, due to its complex biological nature. Over the last 10 years, different strategies have been developed for the management of oral mucositis caused by chemotherapy in cancer patients. Material and Methods An exhaustive search was made of the PubMed-Medline, Cochrane Library and Scopus databases, crossing the key words “oral mucositis”, “prevention” and “treatment” with the terms “chemotherapy” and “radiotherapy” by means of the boolean operators “AND” and “NOT”. A total of 268 articles were obtained, of which 96 met the inclusion criteria. Results Several interventions for the prevention of oral mucositis, such as oral hygiene protocols, amifostine, benzidamine, calcium phosphate, cryotherapy and iseganan, among others, were found to yield only limited benefits. Other studies have reported a decrease in the appearance and severity of mucositis with the use of cytoprotectors (sucralfate, oral glutamine, hyaluronic acid), growth factors, topical polyvinylpyrrolidone, and low power laser irradiation. Conclusions Very few interventions of confirmed efficacy are available for the management of oral mucositis due to chemotherapy. However, according to the reviewed literature, the use of palifermin, cryotherapy and low power laser offers benefits, reducing the incidence and severity of oral mucositis – though further studies are needed to confirm the results obtained.

    The individual oral statement is human story based on experience. The personal experience forms unconsciousness which appears in a form of oral statement by ego that doesn't want to lose existence. Thus, the process which exposes a tormented hearts is the objectification of oneself. Through this step, oral person attains a healing. If this sort of individual oral is accrued, the undeserved personal affairs could be a history. In case of Hansen's disease patient, She could escape from negative understanding about herself and the world. Furthermore, She kept formating her values about meaningful life and future oriented value. Also, She wants to keep a record of her life. She comes to know that what she denied is actually what she should surmount over oral statement. As a result, She could attains a healing for oneself through oral statement. The oral statement made her look into she's problems. Therefore, oral statement is a self-realization. Through this, person could know what the problem is and solution. This research is about only one person, so there is need for more cases and studies. If this sort of individual oral statement is accrued, there could be a curative narration. This can suggest an curative alternative when we suffer from problem of life. The merit of this research is rendering this possibility. PMID:24005645

    We explore Aboriginal oral traditions that relate to Australian meteorite craters. Using the literature, first-hand ethnographic records, and fieldtrip data, we identify oral traditions and artworks associated with four impact sites: Gosses Bluff, Henbury, Liverpool, and Wolfe Creek. Oral traditions describe impact origins for Gosses Bluff and Wolfe Creek craters and non-impact origins of Liverpool and Henbury craters, with Wolfe Creek stories having both impact and non-impact origins. Three impact sites that are believed to have formed during human habitation of Australia - Dalgaranga, Veevers, and Boxhole - do not have associated oral traditions that are reported in the literature.

    The oral carriage rate of Candida in healthy humans ranges from 40% to 60%. However for a prolonged period, the oral candidal prevalence in humans was documented essentially using data from studies in the West as their prevalence in inhabitants in different regions of the world, including Asia was not known. Yet, recent reports from a number of studies indicate the quality, quantity and prevalence of oral yeasts differ between Asia and other regions for reason that are still unclear. This mini review on such data from Asian studies on oral carriage of Candida provides another intriguing facet of the behavior of this ubiquitous yeast.

    Kesarwala, A H; Krishna, M C; Mitchell, J B

    2016-01-01

    Oxidative species, including reactive oxygen species (ROS), are components of normal cellular metabolism and are required for intracellular processes as varied as proliferation, signal transduction, and apoptosis. In the situation of chronic oxidative stress, however, ROS contribute to various pathophysiologies and are involved in multiple stages of carcinogenesis. In head and neck cancers specifically, many common risk factors contribute to carcinogenesis via ROS-based mechanisms, including tobacco, areca quid, alcohol, and viruses. Given their widespread influence on the process of carcinogenesis, ROS and their related pathways are attractive targets for intervention. The effects of radiation therapy, a central component of treatment for nearly all head and neck cancers, can also be altered via interfering with oxidative pathways. These pathways are also relevant to the development of many benign oral diseases. In this review, we outline how ROS contribute to pathophysiology with a focus toward head and neck cancers and benign oral diseases, describing potential targets and pathways for intervention that exploit the role of oxidative species in these pathologic processes.

    Full Text Available Halitosis is a widespread condition and believed to affect one-quarter of the population around the world; also, most people have this condition from time to time. Breath malodour may be an important factor in social communication, and therefore may be the origin of concern not only for a possible health condition but also for frequent psychological alterations, leading to social and personal isolation. The most conspicuous malodorous compounds are termed volatile sulphur compounds (VSCs, with hydrogen sulphide, methyl mercaptan, and dimethyl sulphide accounting for roughly 90% of the VSCs. A number of oral bacteria, especially Gram-negative anaerobic species found in the subgingival plaque, produce a diverse array of malodorous compounds as byproducts of their metabolism, including VSCs and short-chain organic acids. Assessment and management of halitosis is of paramount importance in enhancing the overall health; moreover, dentists play a significant role in combating halitosis by reducing the oral microbial stack. Thus, the aim of the present review was to describe the aetiological factors, assessment tools, and therapeutic approaches related to halitosis.

    Neurocognitive decline and delirium, frailty, incontinence, falls, hearing and vision impairment, medication compliance and pharmacokinetics, skin breakdown, impaired sleep and rest are regarded as geriatric giants by gerontologists, geriatricians and nursing home staff. As these are all interrelated in the elderly, failure to act on one can impact on the others. However, the implications of poor oral health have for too long been ignored and deserve equal status. Mouth pain can be devastating for the elderly, compound psychosocial problems, frustrate carers and nursing home staff and disrupt family dynamics. As appearance, function and comfort suffer, so may a person's self-esteem and confidence. The contributing factors for poor oral health such as rapid dental decay, acute and chronic periodontal infections and compromised systemic health on a background of a dry mouth, coupled with xerostomia-inducing medications, reduced fine motor function, declining cognition and motivation will not only lead to an increase in both morbidity and mortality but also impact on quality of life.

    2015-03-01

    Full Text Available High-risk human papillomaviruses (HR-HPV are considered necessary for the development of cervical cancer. Furthermore, there is no doubt that some types of oral squamous cell carcinoma are associated with HR-HPV. The epidemiology of oral HPV infections in healthy subjects remains unclear due to a lack of knowledge. The objective of this study was to investigate the epidemiology of human papillomavirus infections of the oral mucosa without pathology. A cross-sectional study was performed; samples from 390 women seeking prenatal care, Pap smears, family planning or gynecological diseases were studied. Oral cells were collected by direct swab sampling. Information regarding sociodemographic status, sexual behavior, infectious diseases, contraceptive history and tobacco and alcohol consumption were obtained through direct interviews. HPV and genotypes were detected by type-specific polymerase chain reaction. Our results revealed that 14% of the women studied had an oral HPV infection. Women ≤ 20 years of age had the highest HPV prevalence (24.5%. In total, seven genotypes were identified, including the high-risk genotypes 16, 18, 58 and 59 and the low-risk genotypes 6, 81 and 13, the latter of which is a type exclusive to oral mucosa. Sexual behavior was not associated with the presence of genital HPV types in the oral mucosa. Genital HPV types were present in the oral mucosa of women without associated clinical manifestations; however, sexual behavior was not associated with infection, and therefore others routes of transmission should be explored.

Es difícil definir un afta verdadera ya que siempre se han llamado aftas a ulceraciones y erosiones de muy diverso origen. Este monográfico revisa la bibliografía más reciente acerca de la etiopatogenia, diagnóstico y tratamiento de éstas lesiones. Material y métodos: Se han revisado los estudios publicados desde 2000 hasta el 2008 mediante Pub-Med. Resultados: Las aftas se definen como un estado vesículo-ulceroso sobre una base eritematosa y fondo amarillento y pasan por una serie de periodos. La etiología aún sigue siendo desconocida. Se le atribuye una causa multifactorial y la literatura cuenta con numerosos estudios que sugieren por un lado, una posible base genética y por otro, la existencia de unos factores predisponentes como el trauma, el estrés, determinados alimentos, desequilibrio hormonal y tabaco; se habla incluso de otros posibles factores predisponentes como la actuación de virus o bacterias, deficiencias vitamínicas y factores inmunológicos. Existen tres formas clínicas de aparición que iremos describiendo tales como las aftas menores, aftas mayores y estomatitis aftosa herpetiforme además de una serie de síndromes que cursan con aparición de aftas a nivel oral y que por ello se denominan síndromes aftosos. El desconocimiento de la etiología y la naturaleza cíclica del proceso complican el tratamiento. Se han sugerido numerosas y diversas terapias contando con una amplia literatura al respecto pero con resultados inconsistentes. El tratamiento debe ser diseñado de forma individual y sintomática y persigue unos objetivos principales: acortar el proceso, evitar recidivas y disminuir los síntomas y tamaño de las úlceras durante el brote.Background: Aphthae is a common oral disorder whose definition is difficult due to the general denomination of several ulcerations and erosions as aphthae.

    Full Text Available Esse trabalho investiga um problema combinado de planejamento da produção e corte de estoque comum em fábricas de móveis de pequeno porte, onde os custos de produção envolvidos no processo de manufatura e as demandas dos produtos não são conhecidos com precisão. Para lidar com essas incertezas, foram propostos modelos de otimização robusta que permitem controlar o conservadorismo da solução de acordo com a atitude do decisor em relação ao risco. Experimentos computacionais baseados em dados reais de uma planta moveleira mostraram que é possível obter soluções robustas sem sacrificar em demasia o custo total. Além disso, observou-se que estratégias tipicamente utilizadas na prática para lidar com as incertezas podem gerar planos de produção com custos totais proibitivos.This paper investigates an integrated production planning and cutting stock problem that is common in small-scale furniture plants, in which the production costs involved in the manufacturing process and the demands for the products are not known precisely. To deal with these uncertainties, robust optimization models that control the conservatism of the solution according to the attitude of the decision maker towards risk were proposed. Computational experiments based on real data from a furniture plant showed that it is possible to obtain robust solutions without overly sacrificing the total cost. In addition, it was observed that commonly used strategies to deal with uncertainty issues can result in production plans with prohibitive total costs.

    High level of periodontal problems of dental caries are frequently observed in mentally handicapped children. This group of patients presents various problems when they face dental treatments. Identification of such population and providing them affordable oral health care is the new concept. A systematic method for identification and screening of persons with mental retardation has been developed and is being followed. Cost and fear are the most commonly cited barriers to dental care. Physical or mental may lead to deterioration in self-care, and oral care state have a low priority. Risk factors are inter-related and are often barriers to oral health. With advancements in today's world sufficient information and support is available for each and every individual to lead a healthy life which include the access to the oral health care. Factors such as fear, anxiety and dental phobia plays a vital role in acceptance of dental care and also the delaying of dental care. Lack of knowledge of oral and dental disease, awareness or oral need, oral side-effects of medication and organization of dental services are highlighted in the literature. All health personnel should receive training to support the concept of primary oral health care. Training about dealing with such mentally handicapped people should be addressed urgently among the health professionals. PMID:25738098

    Previous studies have used cryotherapy for the treatment of oral precancers including oral leukoplakia (OL) and oral verrucous hyperplasia (OVH) as well as oral cancers including oral verrucous carcinoma (OVC) and oral squamous cell carcinoma (OSCC). Cryotherapy is a method that locally destroys lesional tissues by freezing in situ. It can be carried out by either an "open" or a "closed" system. Lesional tissues are destroyed mainly through disruption of cell membrane, cellular dehydration, enzyme and protein damage, cell swelling and rupture, thermal shock injury to cells, damage to vasculature, and immune-mediated cytotoxicity. Cryotherapy is used frequently for the treatment of OL lesions with promising results. It can also be used to treat OVH and OVC lesions. Because OVH and OVC lesions are usually fungating and bulky, a combination therapy of shave excision and cryotherapy is needed to achieve a complete regression of the lesion. OSCCs have also been treated by cryotherapy. However, cryotherapy is not the main-stream treatment modality for OSCCs. Cryotherapy seems suitable for treatment of thin or relatively thick plaque-typed lesions such as OL lesions. By careful selection of patients, cryotherapy is a simple, safe, easy, conservative, and acceptable treatment modality for certain benign oral lesions and oral precancers. PMID:24560447

    2002-01-01

    The delivery of proteins has gained momentum with the development of biotechnology sector that provided large-scale availability of therapeutic proteins. The availability is mostly due to the advances in recombinant DNA technology. The low oral bioavailability, however, continues to be a problem for several proteins because of their large molecular size, low permeation through biological membranes, and susceptibility to molecular changes in both biological and physical environments. The demand for effective delivery of proteins by the oral route has brought a tremendous thrust in recent years both in the scope and complexity of drug delivery technology. The important therapeutic proteins and peptides being explored for oral delivery include insulin, calcitonin, interferons, human growth hormone, glucagons, gonadotropin-releasing hormones, enkephalins, vaccines, enzymes, hormone analogs, and enzyme inhibitors. This article reviews the progress in oral delivery of these proteins, provides comments on the strategies to improve their oral bioavailability, and highlights their current market trends.

    2014-12-01

    Full Text Available Fasting is a religious obligation, which can be challenging for individuals with oral conditions due to its stringent code of conduct. Moreover, food abstinence during fasting can restrict oral feeding even further in patients whose nutrition has been already compromised. Previous research has mainly concentrated on oral hygiene and gum health, disregarding orodental conditions and diseases. This highlights the importance of further research in this regard. In this paper, we intended to clarify the correlation between fasting and oral injections, bleeding following tooth extraction, and brushing to overcome common misconceptions which indicate the breach of religious disciplines under such circumstances. We also aimed to determine the grave effects of fasting on health in case of severe immunological deficiencies, chronic oral ulcers and certain drug administration protocols for those with rigid religious beliefs.

  5. Malignant melanoma of the oral cavity

    2006-01-01

    Full Text Available Oral malignant melanoma is a rare disease. The common sites of its occurrence are the palate and gingiva with the maxillary arch being affected 80% of the time. Because of their presence at relatively obscure areas in the oral cavity, most of the malignant melanomas of the oral cavity are diagnosed at a late stage. These lesions are associated with poor prognosis. The dental clinician must therefore carefully examine the head, neck, and oral cavity, and any pigmented lesion that may exhibit growth potential must be biopsied. This article describes a case of malignant melanoma that was present in the oral cavity and briefly reviews the relevant literature that explains the nature of this lesion.

  6. Oral history in radiography: Listening to pioneers

    International Nuclear Information System (INIS)

    We explore the professional value of the collection and analysis of oral histories in the history of radiography. Drawing on oral histories collected from radiographers, we analyse accounts of experiences to identify common themes, some of which are of current significance, whilst others have faded from existence. 15 oral histories were collected from radiographers whose combined practice spans the years 1930-1973. The sample consists of 6 male and 9 female radiographers. Themes identified in the oral histories include radiographers as invisible pioneers who worked in professionally unclaimed territory and their dangerous working environment. The oral histories reveal the working world of the radiographer as having encompassed a practice ethos where challenges became an accepted part of work. We gain insight into less observable aspects of the radiographer's role, the difficulties they faced, how they invented techniques and equipment, and how they managed their practice including protecting the public from ionising radiation sources.

    Input multimodality combining speech and hand gestures has motivated numerous usability studies. Contrastingly, issues relating to the design and ergonomic evaluation of multimodal output messages combining speech with visual modalities have not yet been addressed extensively. The experimental study presented here addresses one of these issues. Its aim is to assess the actual efficiency and usability of oral system messages including brief spatial information for helping users to locate objects on crowded displays rapidly. Target presentation mode, scene spatial structure and task difficulty were chosen as independent variables. Two conditions were defined: the visual target presentation mode (VP condition) and the multimodal target presentation mode (MP condition). Each participant carried out two blocks of visual search tasks (120 tasks per block, and one block per condition). Scene target presentation mode, scene structure and task difficulty were found to be significant factors. Multimodal target presenta...

    Roller, R J; Mallory, A; Caruthers, S B; Schaefer, J W

    1977-08-01

    Retrospective and prospective studies were done to evaluate the efficacy of oral cholecystography (OCG) performed before hospital discharge on alcoholic patients with acute pancreatitis. In the retrospective study, OCG adequately opacified the gallbladder in 21 of 26 patients (81%). Of the 5 patients with inadequate opacification, 1 was jaundiced at the time of OCG; the other 4 had OCG before resumption of solid food. In the prospective study, OCG done in nonjaundiced patients shortly after resumption of food yielded adequate opacification in 19 of 21 patients (90%) without gallstones. We conclude that in nonjaundiced alcoholic patients with acute pancreatitis not caused by gallstones, OCG performed after resumption of a solid diet and before hospital discharge is usually successful in opacifying the gallbladder.

    Patient: Male, 20 Final Diagnosis: Dermographism Symptoms: Unusual skin reaction to trauma Medication: — Clinical Procedure: — Specialty: Dentistry Objective: Unusual clinical course Background: Dermographism is a type of physical urticaria that can be induced by writing on the skin. It occurs in 2–5% of the population and is considered to be a normal physiological phenomenon. However, in a small subset of patients, it can be symptomatic and may affect the quality of life. The etiology of this disease remains unclear. Case Report: Herein, we present a case of dermographism in a 20-year-old male and discuss the involvement of the oral mucosa in this condition. Conclusions: Although this condition is well known to occur in the skin, we believe this condition is rarely discussed among dentists. All healthcare providers, especially dentists, should know its potential to cause complications during dental procedures. PMID:27324161

  13. Moral Violations Reduce Oral Consumption.

    Consumers frequently encounter moral violations in everyday life. They watch movies and television shows about crime and deception, hear news reports of corporate fraud and tax evasion, and hear gossip about cheaters and thieves. How does exposure to moral violations influence consumption? Because moral violations arouse disgust and because disgust is an evolutionarily important signal of contamination that should provoke a multi-modal response, we hypothesize that moral violations affect a key behavioral response to disgust: reduced oral consumption. In three experiments, compared with those in control conditions, people drank less water and chocolate milk while (a) watching a film portraying the moral violations of incest, (b) writing about moral violations of cheating or theft, and (c) listening to a report about fraud and manipulation. These findings imply that "moral disgust" influences consumption in ways similar to core disgust, and thus provide evidence for the associations between moral violations, emotions, and consumer behavior.

    The mortality of oral cancer (OC) has shown only moderate improvement over recent decades. Treatment of OC remains mainly surgical with increasing contributions from radio- and chemotherapy. Early diagnosis and adequate management improves patient prognosis whilst lymphatic spread worsens the prognosis significantly. Copious extirpation of the tumour achieving tumour-free margins, as well as the effective removal of affected or suspect lymph nodes are vital steps to ensure long-term survival. Reconstructive ablities have improved to such an extent that many patients can be fully integrated in society after treatment. New modalities such as intensity modulated radiation therapy (IMRT) or volumetric modulated arc therapy (VMAT) ensures selective radiation and significantly contributes to improved quality of life. Photodynamic therapy and other targeted therapy options will play an increasingly important role in the future. PMID:23957099

  15. Radiotherapy for Oral Cavity Cancer

    International Nuclear Information System (INIS)

    Eighty five patients of oral cavity cancer, treated with radiation at the Department of Therapeutic Radiology, Korea Cancer Center Hospital, during the period from March 1985 to September 1990 were analyzed retrospectively. Among 85 patients, 37 patients were treated with radiation only and 48 patients were treated with radiation following surgery And 70 patients received external irradiation only by 60Co with or without electron, the others were 7 patients for external irradiation plus interstitial implantation and 8 patients for external irradiation plus oral cone electron therapy. Primary sites were mobile tongue for 40 patients, mouth floor for 17 patients, palate for 12 patients, gingiva including retromolar trigone for 10 patients, buccal mucosa for 5 patients, and lip for 1 patient. According to pathologic classification, squamous cell carcinoma was the most common (77 patients). According to AJC TNM stage, stage I + II were 28 patients and stage III + IV were 57 patients. Acturial overall survival rate at 3 years was 43.9%, 3 year survival rates were 60.9% for stage I + II, and 23.1% for stage III + IV, respectively. As a prognostic factor, primary T stage was a significant factor (p<0.01). The others, age, location, lymph node metastasis, surgery, radiation dose, and cell differentiation were not statistically significant. Among those factors, radiation plus surgery was more effective than radiation only in T3 + T4 or in any N stage although it was not statistically sufficient(p<0.1). From those results, it was conclusive that definitive radiotherapy was more effective than surgery especially in the view of pertaining of anatomical integrity and function in early stage, and radiation plus surgery was considered to be better therapeutic tool in advanced stage

    Full Text Available The aim of this paper is to make known the potential of fluoridated salt in community oral health programs, particularly in South Eastern Europe. Since 1922, the addition of iodine to salt has been successful in Switzerland. Goiter is virtually extinct. By 1945, the cariesprotective effect of fluorides was well established. Based on the success of water fluoridation, a gynecologist started adding of fluoride to salt. The sale of fluoridated salt began in 1956 in the Swiss Canton of Zurich, and several other cantons followed suit. Studies initiated in the early seventies showed that fluoride, when added to salt, inhibits dental caries. The addition of fluoride to salt for human consumption was officially authorized in 1980-82. In Switzerland 85% of domestic salt consumed is fluoridated and 67% in Germany. Salt fluoridation schemes are reaching more than one hundred million in Mexico, Colombia, Peru and Cuba. The cost of salt fluoridation is very low, within 0.02 and 0.05 € per year and capita. Children and adults of the low socio-economic strata tend to have substantially more untreated caries than higher strata. Salt fluoridation is by far the cheapest method for improving oral health. Conclusions. Salt fluoridation has cariostatic potential like water fluoridation (caries reductions up to 50%. In Europe, meaningful percentages of users have been attained only in Germany (67% and Switzerland (85%. In Latin America, there are more than 100 million users, and several countries have arrived at coverage of 90 to 99%. Salt fluoridation is by far the cheapest method of caries prevention, and billions of people throughout the world could benefit from this method.

    The incidence of inflammatory bowel diseases (IBD) - Crohn's disease (CD) and ulcerative colitis (UC) - has been increasing on a global scale, and progressively, more gastroenterologists will be included in the diagnosis and treatment of IBD. Although IBD primarily affects the intestinal tract, extraintestinal manifestations of the disease are often apparent, including in the oral cavity, especially in CD. Specific oral manifestations in patients with CD are as follows: indurate mucosal tags, cobblestoning and mucogingivitis, deep linear ulcerations and lip swelling with vertical fissures. The most common non-specific manifestations, such as aphthous stomatitis and angular cheilitis, occur in both diseases, while pyostomatitis vegetans is more pronounced in patients with UC. Non-specific lesions in the oral cavity can also be the result of malnutrition and drugs. Malnutrition, followed by anemia and mineral and vitamin deficiency, affects the oral cavity and teeth. Furthermore, all of the drug classes that are applied to the treatment of inflammatory bowel diseases can lead to alterations in the oral cavity due to the direct toxic effects of the drugs on oral tissues, as well as indirect immunosuppressive effects with a risk of developing opportunistic infections or bone marrow suppression. There is a higher occurrence of malignant diseases in patients with IBD, which is related to the disease itself and to the IBD-related therapy with a possible oral pathology. Treatment of oral lesions includes treatment of the alterations in the oral cavity according to the etiology together with treatment of the primary intestinal disease, which requires adequate knowledge and a strong cooperation between gastroenterologists and specialists in oral medicine.

  18. Oral Tolerance: Therapeutic Implications for Autoimmune Diseases

    Directory of Open Access Journals (Sweden)

    Ana M. C. Faria

    2006-01-01

    Full Text Available Oral tolerance is classically defined as the suppression of immune responses to antigens (Ag that have been administered previously by the oral route. Multiple mechanisms of tolerance are induced by oral Ag. Low doses favor active suppression, whereas higher doses favor clonal anergy/deletion. Oral Ag induces Th2 (IL-4/IL-10 and Th3 (TGF-β regulatory T cells (Tregs plus CD4+CD25+ regulatory cells and LAP+T cells. Induction of oral tolerance is enhanced by IL-4, IL-10, anti-IL-12, TGF-β, cholera toxin B subunit (CTB, Flt-3 ligand, anti-CD40 ligand and continuous feeding of Ag. In addition to oral tolerance, nasal tolerance has also been shown to be effective in suppressing inflammatory conditions with the advantage of a lower dose requirement. Oral and nasal tolerance suppress several animal models of autoimmune diseases including experimental allergic encephalomyelitis (EAE, uveitis, thyroiditis, myasthenia, arthritis and diabetes in the nonobese diabetic (NOD mouse, plus non-autoimmune diseases such as asthma, atherosclerosis, colitis and stroke. Oral tolerance has been tested in human autoimmune diseases including MS, arthritis, uveitis and diabetes and in allergy, contact sensitivity to DNCB, nickel allergy. Positive results have been observed in phase II trials and new trials for arthritis, MS and diabetes are underway. Mucosal tolerance is an attractive approach for treatment of autoimmune and inflammatory diseases because of lack of toxicity, ease of administration over time and Ag-specific mechanism of action. The successful application of oral tolerance for the treatment of human diseases will depend on dose, developing immune markers to assess immunologic effects, route (nasal versus oral, formulation, mucosal adjuvants, combination therapy and early therapy.

    Full Text Available Objectives: The aims of the study were to assess current practice in oral health care among residential homes for the elderly in Manchester, Salford and Stockport and to evaluate the effectiveness of a programme to increase carers’ knowledge in key areas. Methods: The study was part of a randomised control trial, conducted in 56 residential homes, allocated randomly to test and control groups matched using the minimisation method. Managers of participating homes were interviewed to gather baseline data on the homes and oral care provided. A training session in oral health care for the elderly was provided for care staff in the homes. Carers` knowledge was assessed before and after the training session and their perceptions of the training were sought. Results: The survey of mangers revealed common inadequacies: the lack of any training for care staff in oral care; the lack of protocols for oral care (at 68% of homes; the lack of initial oral assessment. After the training session, the oral health knowledge of carers (467 carers showed a significant improvement (McNemar Test, P< 0.005. Conclusion: Current practice in most homes is inadequate. The training sessions improved the carers’ knowledge in key areas but improvements in the organisation and delivery of care are clearly also required.

    2016-01-01

    This study aimed to evaluate objectively and subjectively the oral health of elders with Parkinson's disease (PD), using clinical oral assessments and the General Oral Health Assessment Index (GOHAI). Subjects included 37 removable prosthesis wearers, 17 with PD (mean age 69.59±5.09 years) and 20 without PD (mean age 72.00±5.69 years). The objective assessment included an evaluation of oral characteristics, including the number of remaining teeth, decayed, missing and filled teeth (DMFT), visible plaque index (VPI), salivary flow rate and removable prosthesis conditions. The subjective assessment included self-perception of oral health collected using the GOHAI index. The number of remaining teeth, DMFT, VPI, salivary flow rate and GOHAI data were compared between the groups using t-tests. Removable prosthesis conditions were analyzed using χ2 tests (p0.05). Greater maxillary prosthesis defects were observed in the control group (p=0.037). GOHAI scores were low for the PD group and moderate for controls, yielding a group difference (p=0.04). In conclusion, elders with PD have similar oral health to controls. Although all elders had few remaining teeth, high DMFT and high VPI, PD elders had more negative self-perceptions of their oral health than did the controls. PMID:27224571

Worldwide 5-year survival is only 50% due to delayed intervention with more than half of the diagnoses at stage III and IV, whereas earlier detection (stage I and II) yields survival rates up to 80% to 90%. Salivary soluble CD44 (CD44), a tumor-initiating marker, and total protein levels may facilitate oral cancer risk assessment and early intervention. This study used a hospital-based design with 150 cases and 150 frequency-matched controls to determine whether CD44 and total protein levels in oral rinses were associated with oral cancer independent of age, gender, race, ethnicity, tobacco and alcohol use, and socioeconomic status (SES). High-risk subjects receiving oral cancer prevention interventions as part of a community-based program (n = 150) were followed over 1 year to determine marker specificity and variation. CD44 ≥5.33 ng/mL was highly associated with case status [adjusted OR 14.489; 95% confidence interval (CI), 5.973-35.145; P cancer. In contrast, specificity in the high-risk community was 74% and reached 95% after annual retesting. Simple and inexpensive salivary CD44 and total protein measurements may help identify individuals at heightened risk for oral cancer from the millions who partake in risky behaviors.

    Full Text Available Myiasis is a rare disease primarily caused by the invasion of tissue by larvae of certain dipteran flies. Oral myiasis is still more "rare" and "unique" owing to the fact that oral cavity rarely provides the necessary habitat conducive for a larval lifecycle. Common predisposing factors are poor oral hygiene, halitosis, trauma, senility, learning disabilities, physically and mentally challenged conditions. Oral myiasis can lead to rapid tissue destruction and disfigurement and requires immediate treatment. Treatment consists of manual removal of maggots from the oral cavity after application of chemical agents. Good sanitation, personal and environmental hygiene and cleanliness and special care for debilitated persons are the best methods to prevent oral myiasis. This case report describes the presentation of oral myiasis caused by musca nebulo (common house fly in a 40-year-old male patient, with recent maxillofacial trauma. The patient was treated by manual removal larvae by topical application of turpentine oil, followed by surgical debridement of the wound and open reduction and internal fixation of the fracture.

    As the public's oral health care needs increase in complexity, there is renewed attention to the ethical dimensions of community oral health decision making and the development of public health ethics in teaching and research in dentistry. Despite their reduction globally, oral diseases persist with a particular distribution pattern that is a reflection of the increasingly widespread inequality in access to community oral health preventive and dental care. This is due to differences in the appropriateness, availability, accessibility, and acceptability of oral health education and the care provided. This article provides an overview of community oral health from an ethical perspective, including the importance of equity, human rights, and social justice in providing oral health care to the underserved. The need for a paradigm shift from highly technical and individualistic dental training curricula is discussed, together with the need to instill a holistic approach to ethical and social responsibility in new dental graduates. It concludes with some possible strategies, using the overarching principles of ethics and bioethics that are applicable to practice among vulnerable populations. PMID:25941240

    Voriconazole (VRCZ), a broad-spectrum triazole, is served in two dosage forms-injection and oral. VRCZ is difference dosage of oral and intravenous administration writing a medical package insert in Japan. 6 mg/kg intravenous injection (IV) twice daily for first day as initial loading dose, followed by 3-4 mg/kg IV twice daily between meals is recommended. 300 mg orally twice daily for first day as initial loading dose, followed by 150-200 mg orally twice daily between meals is recommended. Patients weighing over 40 kg, 200 mg orally twice daily between meals is recommended. Patients weighing under 40 kg, 100 mg orally twice daily between meals is recommended, increase to 150 mg twice daily if inadequate response. This study evaluated VRCZ trough concentration and oral dosage in the 23 cases which administered VRCZ to analysis for TDM in Aichi University Hospital. Spearman rank correlation coefficient was calculated to examine relationships among variables. The level of statistical significance was set at p=0.05. All data were analyzed and processed on JMP 8 (SAS Institute Japan). There was a significant positive correlation between VRCZ trough concentration and dose/weight (r=0.47 poral dosage is appropriate to administer dose/weight (mg/kg) twice a day as same as IV.

    Full Text Available Objectives: The study aims to establish an etiological association between diabetes and precancerous lesions of the oral cavity by cytomorphometric analysis of the oral epithelium. Study Design: Smears were obtained from three distinct oral sites - buccal mucosa, dorsum of the tongue and the floor of the mouth in ten controls and ten patients previously diagnosed with type II diabetes. The oral smears were stained with Papanicolaou SA-36 solution. An eye - piece graticule was used to obtain the cytoplasm and nuclear dimension; where larger dimension was denoted as "D" and the smaller dimension was denoted as "d". The nuclear area (NA, nuclear diameter (ND, cytoplasmic area (CA and the cytoplasmic / nuclear ratio (C/N were evaluated from 50 cells predominant in each oral site. Statistical Analysis: The cytomorphometric data obtained was compared between the group of diabetic patients and the control groups using the student′s t- test (SPSS version 11.0. Results: Results showed that the nuclear area and the nuclear diameter of oral epithelial cells were increased in diabetic patients, as compared to non- diabetics, while the non- diabetic patients demonstrated an increase in nuclear ratio. Conclusions: The results from this study suggest that diabetes mellitus can cause alterations in oral epithelial cells that are detectable with exfoliative cytology.

    Oral cancer is historically linked to well-known behavioural risk factors such as tobacco smoking and alcohol consumption. Other risk factors include age over 40, male sex, several dietary factors, nutritional deficiencies, viruses, sexually transmitted infections, human papillomavirus, chronic irritation, and possibly genetic predisposition. Precancerous lesions in the oral cavity include leukoplakia, erythroplakia, and lichen planus. Histology of oral cancer varies widely but the great majority are squamous cell carcinomas.Epidemiological studies and cancer registries have shown a consistently increased risk of oral malignancies in kidney, bone marrow, heart, or liver transplantation, in graft vs host disease, and in patients with HIV infection. Because of the increasing use of immunosuppressive drugs in patients with inflammatory bowel disease, it is useful to more accurately delineate the consequences of chronic immunosuppression to the oral cavity. Oral cancer and precancerous oral lesions in patients with inflammatory bowel disease [IBD] have been scarcely reported and reviews on the topic are lacking.We conducted a literature search using the terms and variants of all cancerous and precancerous oral manifestations of inflammatory bowel diseases. By retrieving the existing literature, it is evident that patients with IBD belong to the high-risk group of developing these lesions, a phenomenon amplified by the increasing HPV prevalence. Education on modifiable risk behaviours in patients with oral cancer is the cornerstone of prevention.Oral screening should be performed for all IBD patients, especially those who are about to start an immunosuppressant or biological drug.

    Full Text Available Introduction. It has been suggested that asthmatic patients may have a higher risk for oral diseases, both as a result of the medical condition and effects of medications. Objective. The aim of the study was to determine the oral health status of children with asthma and to evaluate the oral health parameters according to the medications and severity of the disease. Methods. The study group consisted of 158 children with asthma and 100 healthy control subjects aged 2-18 years. The diagnosis of dental caries was performed using the Decayed, Missing, and Filled Teeth (DMFT/dmft criteria. The oral hygiene, periodontal status and gingival health were assessed with the Simplified Oral Hygiene Index (Greene-Vermillion, Community Periodontal Index of Treatment Needs and Gingival Index (Löe-Silness, respectively. Results. Thirty (19% patients with asthma and 43 (43% healthy children were caries-free (p<0.001. There were no significant differences between asthmatic and control children in caries experience (for children with asthma mean DMFT=2.1±1.8, mean dmft=4.2±3.3; for healthy children mean DMFT=2.5±0.9, mean dmft=5.2±1.3. Level of asthma control did not have influence on dental health, while dose of inhaled corticosteroid had impact on primary dentition. Periodontal status and gingival health did not differ between asthmatic and control children. However, children with asthma had poorer oral hygiene (p<0.001. Conclusion. Results of the study do not show a relationship between asthma and oral diseases. However, further improvement could be made in educating children and parents on the importance of good oral hygiene and prevention of oral diseases.

    Full Text Available Oral allergy syndrome (OAS is an allergic reaction in the oral cavity subsequent to the consumption of food such as fruits, nuts, and vegetables. It occurs mainly due to homology of proteins of pollen to the proteins of fruits and vegetables. In OAS, the immune system produces antibodies that are directed against the proteins of pollen and structurally similar proteins in food, hence, resulting in allergic symptoms limited mainly to the oral cavity. In this review, we have summarized the etiopathogenesis, clinical features, diagnosis, and management of OAS as an update for stomatologists.

    Full Text Available We report an unusual case of a glial heterotopia arising from the oral cavity of an African neonate. The patient presented with an external pedunculated oral mass which was connected to the anterior hard palate by a firm, rubbery stalk of mucosal tissue. While the mass appeared painless, it interfered with the infant's feeding and was disturbing to the parents. After a computed tomography scan excluded an intracranial connection, the mass was excised at its base and sent for biopsy. Histopathology examination confirmed glial heterotopia. Glial heterotopias should be included in the differential diagnosis of congenital masses in the oral region.

    The oral cavity is an area of the human body that is often given only cursory surveillance by primary care physicians. In this article, I have discussed a comprehensive approach for collecting subjective and objective data from the patient that is pertinent to oral conditions. Most common and critical problems have been reviewed in detail, focusing on their definition, epidemiology, pathophysiology, clinical manifestations, diagnosis, and management. This review is intended to sensitize physicians to the need to evaluate oral complaints more completely, to diagnose them more accurately, and to treat them more successfully. PMID:2196616
