    Full Text Available Introducción: La premedicación anestésica está destinada a reducir la ansiedad y la respuesta al estrés que supone el período anterior a la intervención quirúrgica. El temor a lo desconocido, al dolor y la separación de los padres son elementos que se añaden a la ansiedad perioperatoria en la población pediátrica. La necesidad de encontrar una vía de administración idónea en niños que no añada más sufrimientos a los ya existentes, es un reto para los anestesiólogos. Objetivo: Los objetivos del presente estudio eran valorar la eficacia, el grado de sedación y el modo de aceptación de 2 modalidades de premedicación para niños: citrato de fentanilo oral transmucoso (CFOT y midazolam oral disuelto en zumo de fruta. Material y método: Se estudiaron 2 grupos aleatorizados de 40 niños que iban a someterse a cirugía de diversas especialidades. Las dosis administradas fueron de 10 μg/kg de CFOT y 0,3 mg/kg de midazolam, administrados 30 minutos antes de la punciσn venosa. Las variables consideradas fueron: saturaciσn de hemoglobina desde el inicio de la premedicaciσn y en la sala de despertar, modo de aceptaciσn, grado de sedaciσn, actitud del niρo al separarlo de los padres, ante la punción venosa y ante la inducción anestésica, retraso en el despertar, requerimiento de analgesia postoperatoria, aparición de efectos secundarios. Resultados: Los resultados se compararon utilizando la t de Student (p Introduction: The aim of anaesthetic premedication is to reduce anxiety and stress prior to surgery. Paediatric patients suffer even more anxiety due to fear of the unknown and the separation from parents. The need to find out a suitable way of administering premedication to paediatric patients without causing any more trauma is a challenge for the anaesthesiologist. Objectives: The objective of the current study was to evaluate the efficacy, level of sedation and a way of accepting two different types of premedication for

    Full Text Available Objetivo: El dolor irruptivo es una necesidad clínica desconocida que todavía se diagnostica poco y, por lo tanto, se evalúa y se trata de modo inadecuado. Concretamente, en los pacientes oncológicos se puede presentar un dolor rectal irruptivo defecatorio debido al tumor, los efectos secundarios de los tratamientos administrados (cirugía, radioterapia y/o quimioterapia o ambos. Recientemente, ha aparecido un sistema de administración transmucosa oral, citrato de fentanilo oral transmucosa (CFOT (Actiq® como método de alta eficacia para un inicio rápido de la analgesia. El objetivo de este trabajo es valorar la eficacia de CFOT como analgésico en este subgrupo tan específico de pacientes oncológicos. Pacientes y métodos: Entre enero de 2006 y julio de 2009 hemos revisado retrospectivamente un total de 10 pacientes tratados en nuestro servicio con CFOT por dolor rectal irruptivo defecatorio no premedicados con opiáceos. Cuando los pacientes referían en consulta dolor rectal se les valoraba con una escala visual analógica (EVA (0-10. Resultados: La puntuación media premedicación con CFOT de dolor irruptivo defecatorio con la EVA fue de 7 (rango: 5-9. La puntuación media tras el tratamiento pasó a ser 1,9 (rango: 1-3. Todos refirieron controlar el dolor con dosis de 200 µg de CFOT, salvo 2 pacientes que precisaron dosis progresivas de 400 y 600 µg, respectivamente. El grado de satisfacción de los pacientes fue excelente-bueno en el 90% de los casos. Ningún paciente refirió efectos indeseables relacionados con el uso de CFOT. Conclusiones: Aunque nuestra serie es corta y, por lo tanto, sus resultados son muy preliminares, podemos recomendar el CFOT como analgésico ideal por su rapidez y seguridad para el tratamiento del dolor rectal irruptivo defecatorio. Es de fácil y cómoda administración, y de corta duración. Ofrece al paciente independencia al poderlo tomar, aunque se encuentre fuera de su domicilio. CFOT se puede

    Full Text Available Objetivos: Exponer los resultados obtenidos en 250 pacientes que sin haber tenido contacto previo con opioides, acceden a nuestra Unidad de Tratamiento del Dolor, padeciendo un dolor intenso (EVA ≥ 8 de más de 6 meses de evolución y afectos de un dolor de origen osteoarticular. Métodos: Estudio abierto, prospectivo y controlado. Los pacientes fueron tratados, inicialmente, con fentanilo TTS matricial de 12 µg/h + citrato de fentanilo oral transmucosa (CFOT de 200-400 pg., para el dolor irruptivo. A los 12 días de tratamiento, se aumento la dosificación del parche matricial de fentanilo TTS, a 25 ug/h. Se valoró la situación de los pacientes mensualmente y si el dolor no estaba controlado, se aumento la dosificación de fentanilo TTS matricial. Si por el contrario, el dolor permanecía controlado durante más de un mes y no se precisaba ningún comprimido de CFOT, se redujo la dosificación del fentanilo TTS matricial. Se analizaron los registros de intensidad del dolor, calidad del descanso nocturno, efectos secundarios y consumo medio de fetanilo TTS y CFOT, obtenidos al inicio, 1º, 3º y 6º mes de tratamiento. Resultados: La EVA medio pasó del 8,86 + 0,25, inicial hasta un 2,1 + 0,74, al 6º mes. El descanso nocturno, mejoró en una proporción idéntica a la del alivio del dolor. Solo 17 pacientes (6,80% abandonaron el tratamiento por efectos secundarios 11 por náuseas-vómitos, 5 por sedación excesiva y 1 por dermatitis. Al final del estudio, solo 1 paciente precisaba dosis superiores a los 100 µg/h. de fentanilo TTS.

    crisis de DI en pacientes oncológicos que tienen controlado su dolor basal con dosis altas de opioides. Las dosis de CFOT pueden considerarase como bajas en relación a las utilizadas para su dolor basal. Su administración y titulación es sencilla, aunque el paciente requiere de una educación previa a su uso.The management of breakthrough pain in cancer patients treated with high doses of opiates raises particular problems, such as the election of the drug to be used, the appropriate dosage and the route of administration. No clear guidelines on this issue are found in the medical literature, so each service decides its own particular way of acting. In this paper we review the cases dealt with over a one-year period in terms of the use of high doses of opiates in cancer patients taken care of in 2003 and treated with opiates. Objectives: -To study the group of patients treated with high doses of opiates. -To use OTFC as rescue drug for breakthrough pain events. -To analyze side and toxic effects. -To determine the preferences of the patients. Material and methods: A population of 280 patients with advanced cancer, 25 of which were receiving high doses of opiates. In these patients, breakthrough pain crises were managed with OTFC, starting with 400 micrograms. The satisfaction questionnaire proposed by Kornick was used. Results: -Easy adherence to treatment. -Average effective dose of OTFC: 600 micrograms, median of 627. -Dose titration on the second day. -Seventeen patients preferred OTFC, 6 preferred oral morphine and 2 were indifferent. Conclusions: Easy use of OTFC for the management of breakthrough pain, requiring low doses compared to the total daily dose of the patient. Patient education is required before its administration.

    Full Text Available Introducción: Se denomina dolor irruptivo o episódico a la crisis dolorosa de intensidad elevada y aparición brusca que se instaura sobre un dolor crónico de base controlado con opioides. El citrato de fentanilo oral transmucosa (CFOT es un fármaco recientemente introducido en nuestro país, que ha sido específicamente desarrollado para el tratamiento de este tipo de dolor. Tras su comercialización en el año 2001, se planteó la realización de un estudio observacional post-autorización con el objetivo de evaluar la seguridad y tolerabilidad del mismo. Adicionalmente se planteó la obtención de datos de efectividad del CFOT y la comparación de los mismos con los obtenidos hasta la visita basal para otros tratamientos administrados, distintos a CFOT. Métodos: Para el estudio se reclutaron 312 pacientes oncológicos, con dolor de base controlado con opioides, que presentaban crisis de dolor irruptivo y fueron seguidos durante un mes, realizándose visitas de control semanales. Doscientos noventa y cinco pacientes fueron válidos para el estudio de la seguridad y tolerabilidad de CFOT (población de seguridad. Por otra parte, 138 pacientes fueron evaluados para efectividad, ya que cumplían los criterios de inclusión y exclusión del estudio y les habían sido administrados tratamientos distintos a CFOT antes de la visita basal. Se determinaron las siguientes variables: disminución de la intensidad del dolor tras la administración del tratamiento mediante una escala visual analógica (EVA de 0 a 10 puntos, el tiempo transcurrido hasta que se producía el inicio del alivio del dolor y el alivio máximo tras el tratamiento administrado. Resultados: Seguridad: de los 295 pacientes evaluados, 59 (20% presentaron alguna reacción adversa. Todas ellas fueron de intensidad leve o moderada. No se notificó ninguna reacción adversa grave durante el desarrollo del estudio. Las reacciones más frecuentemente descritas fueron las de origen

    Full Text Available La enfermedad renal crónica (ERC es una situación clínica cada vez más prevalente. Esto se debe en gran medida al aumento de la esperanza de vida y al incremento de la incidencia de la diabetes mellitus (DM y la hipertensión arterial (HTA. Estos pacientes requieren un manejo cuidadoso de la analgesia postoperatoria. El fentanilo es un fármaco cuya farmacocinética encaja en el manejo del dolor en la ERC. Sus diferentes presentaciones comerciales permiten elaborar estrategias adecuadas para brindarles una analgesia postoperatoria de gran calidad. Presentamos el esquema de analgesia postoperatoria de un paciente en fallo renal severo sometido a artroplastia de cadera: metamizol (6 gramos/24 horas en perfusión durante 48 horas, fentanilo transcutáneo TTS 25 microgramos/hora durante 48 horas y fentanilo oral transmucosa 200 microgramos en caso de exacerbación del dolor. Este tratamiento analgésico permitió el control satisfactorio del dolor sin que se presentaran vómitos, prurito ni estreñimiento; la calidad del sueño y el descanso nocturno fueron buenos.

    Full Text Available Con elevada frecuencia, a los niños afectos de leucemias y otras enfermedades neoplásicas se les deben realizar una serie de pruebas diagnósticas y de tratamientos (punciones de médula ósea, administración intratecal de medicamentos… que producen dolor y que aumentan considerablemente el disconfort y sufrimiento o impiden la realización de las técnicas. La realización de técnicas de sedación consciente con fármacos utilizados por vía oral como el fentanilo (Citrato de Fentanilo Oral Transmucosa -OTFC- junto con midazolam, y el empleo de anestésico local en el lugar de punción, puede hacer que estas técnicas dolorosas sean bien toleradas por parte del paciente, evitando así el dolor y disminuyendo la angustia, el miedo y sufrimiento que representa para los niños la realización de cualquier prueba o tratamiento.Multiple bone marrow aspirations and lumbar punctures are performed on children with leukaemia and other neo-plastic disorders during the course of their illnesses. These procedures may give rise to considerable pain and distress in children. Fentanyl, a short-acting potent synthetic opioid, can produce sedation through oral transmucosal (Oral Transmucosal Fentanyl Citrate -OTFC- administration. The combination of OTFC and oral midazolam was a useful conscious sedation technique for painful procedures, such as lumbar punctures and bone marrow aspirations in this patients.

    Full Text Available El citrato es un potente inhibidor de la cristalización de sales de calcio. La hipocitraturia es una alteración bioquímica frecuente en la formación de cálculos de calcio en adultos y especialmente en niños. El pH ácido (sistémico, tubular e intracelular es el principal determinante de la excreción de citrato en la orina. Si bien la mayoría de los pacientes con litiasis renal presentan hipocitraturia idiopática, hay un número de causas para esta anormalidad que incluyen acidosis tubular renal distal, hipokalemia, dietas ricas en proteínas de origen animal y/o dietas bajas en álcalis y ciertas drogas, como la acetazolamida, topiramato, IECA y tiazidas. Las modificaciones dietéticas que benefician a estos pacientes incluyen: alta ingesta de líquidos y frutas, especialmente cítricos, restricción de sodio y proteínas, con consumo normal de calcio. El tratamiento con citrato de potasio es efectivo en pacientes con hipocitraturia primaria o secundaria y en aquellos desordenes en la acidificación, que provocan un pH urinario persistentemente ácido. Los efectos adversos son bajos y están referidos al tracto gastrointestinal. Si bien hay diferentes preparaciones de citrato (citrato de potasio, citrato de sodio, citrato de potasio-magnesio en nuestro país solo está disponible el citrato de potasio en polvo que es muy útil para corregir la hipocitraturia y el pH urinario bajo, y reducir marcadamente la recurrencia de la litiasis renal.

    Full Text Available Breakthrough cancer pain is a component of chronic cancer pain that is particularly difficult to treat due to its severity and rapid onset. Effective relief of cancer pain is an integral part of comprehensive cancer care. Many cancer patients experience persistent pain that is treated with a fixed scheduled opioid regimen. But these patients can experience acute breakthrough pain, with sudden onset that occurs spontaneously or as a result of activity. To supply this occurrence is indicated an addictional prescription of opioids. The ideal preparation for managing breakthrough pain is one that is able to mirror its characteristics, i.e. rapid in onset and relatively short in duration. Oral transmucosal fentanyl (Actiq®, an innovative form of fentanyl citrate, provides a rapid onset of pain relief and it is more appropriate than morphine for treating episodes of breakthrough pain. Besides the impact on the patients’ quality of life, cancer pain involves remarkable expenditures, as direct and indirect costs, by the National Health Care System and the Society. This study presents the estimation of the costs associated with the use of oral transmucosal fentanyl (Actiq®. Aim of the study is to verify if the use of oral transmucosal fentanyl (Actiq® can be considered as cost saving or cost effective compared with current therapy.

    Full Text Available El control del dolor en el paciente oncológico es un aspecto importante en la calidad de la asistencia a las personas. El fármaco de elección en el tratamiento del DIO requiere una potencia adecuada y una muy rápida velocidad de absorción. Esta velocidad es un aspecto crítico. Las preparaciones de fentanilo, debido a su gran potencia, son probablemente los fármacos que el clínico debe emplear en el DIO, pero no todas las preparaciones de fentanilo presentan una cinética similar. Las propiedades farmacocinéticas del comprimido bucal de fentanilo (CBF con tecnología OraVescent®, han mostrado una gran velocidad de absorción, mucho más rápida que otras preparaciones de opiáceos. Se dispone de evidencia suficiente que indica que la preparación de CBF es eficaz en los episodios de DIO. El CBF ha mostrado eficacia también en dolor irruptivo no relacionado con el cáncer.

    Full Text Available Introducción: La prevalencia del dolor irruptivo (DI es > 55 % en los pacientes no oncológicos y cercana al 70 % en pacientes con dolor crónico. El DI deteriora el estado funcional y emocional de los pacientes, lo cual se traduce en una menor calidad de vida. Se ha descrito que un 50 % de la población oncológica anciana podría padecerlo, pero en ancianos no oncológicos los datos disponibles sobre el tratamiento del DI son limitados. Objetivos: El objetivo primario de este estudio fue valorar la calidad de vida y la satisfacción del paciente anciano no oncológico con DI tratado con fentanilo sublingual. Los objetivos secundarios fueron evaluar el cambio en la intensidad del dolor, el número de episodios de DI y el tiempo de respuesta al tratamiento con fentanilo sublingual, y describir su perfil de seguridad. Material y métodos: Estudio retrospectivo multicéntrico realizado en 78 pacientes con un periodo de recogida de datos de un mes. Se eligió a pacientes > 70 años, con DI (EVA ≥ 6 y tratamiento de base con opioides, a los cuales se les hubiera prescrito citrato de fentanilo sublingual para el tratamiento del DI.

    Full Text Available Polímeros sintéticos biorreabsorvíveis podem ser utilizados sob a forma de membranas para sustentar e guiar o crescimento celular, através do processo de reparação tecidual. Este trabalho avaliou membranas de poli(ácido lático, PLLA, com adição de 10% de trietil-citrato usadas como curativos de feridas cutâneas agudas em ratos Wistar. Inicialmente uma ferida de 2cm² foi provocada na região dorsal de 24 animais. Estes foram divididos em 2 grupos: tratamento, nos quais as feridas foram recobertas pela membrana polimérica e controle, com feridas permanecendo cruentas. Os resultados obtidos em 1, 3, 7 e 15 dias mostraram uma resposta inflamatória mais satisfatória nas feridas protegidas pelas membranas, com reparação precoce e colágeno mais organizado quando comparadas com as áreas incialmente mantidas sem proteção. Além do que, as áreas protegidas pelas membranas não mostraram alterações inflamatórias irritativas que pudessem ser imputadas ao uso da membrana polimérica. Diante disso, conclui-se que a membrana de PLLA/Trietil-citrato protegeu efetivamente as feridas, permitindo o processo de reparação e mostrando-se promissora como curativo cutâneo.

    2011-06-01

    Full Text Available OBJETIVO: Um amplo corpo de evidência oriundo de estudos experimentais indica que a sepse se associa com um aumento da produção de espécies de oxigênio reativo, depleção de antioxidantes, e acúmulo de marcadores de estresse oxidativo. Além disto, a disfunção mitocondrial foi implicada na patogênese da síndrome de disfunção de múltiplos órgãos. A citrato sintase é uma enzima que se localiza no interior das células, na matriz mitocondrial, sendo uma etapa importante do ciclo de Krebs; esta enzima foi utilizada como um marcador enzimático quantitativo da presença de mitocôndrias intactas. Assim, investigamos a atividade da citrato sintase no cérebro de ratos submetidos ao modelo sepse com de ligadura e punção do ceco. MÉTODOS: Em diferentes horários (3, 6, 12, 24 e 48 horas após cirurgia de ligadura e punção do ceco, seis ratos foram sacrificados por decapitação, sendo seus cérebros removidos e dissecados o hipocampo, estriato, cerebelo, córtex cerebral e córtex pré-frontal, e utilizados para determinação da atividade de citrato sintase. RESULTADOS: Verificamos que a atividade de citrato sintase no córtex pré-frontal estava inibida após 12, 24 e 48 horas da ligadura e punção do ceco. No córtex cerebral, esta atividade estava inibida após 3, 12, 24 e 48 horas da ligadura e punção do ceco. Por outro lado a citrato sintase não foi afetada no hipocampo, estriato e cerebelo até 48 horas após a ligadura e punção do ceco. CONCLUSÃO: Considerando-se que é bem descrito o comprometimento da energia decorrente da disfunção mitocondrial na sepse, e que o estresse oxidativo desempenha um papel essencial no desenvolvimento da sepse, acreditamos que o comprometimento da energia pode também estar evolvido nestes processos. Se a inibição da citrato sintase também ocorre em um modelo de sepse, é tentador especular que a redução do metabolismo cerebral pode provavelmente estar relacionada com a

Fentanilo presentó un efecto analgésico dosis y tiempo dependiente ante los dos estímulos nociceptivos. Paralelamente a la aparición del efecto analgésico, fentanilo originó una regulación a la alta de los receptores 5-HT1A al incrementar de forma dosis-dependiente su densidad sin modificar su afinidad. La dosis mayor de fentanilo (12,8 µg.kg-1 originó un incremento de la densidad de los receptores 5-HT1A estadísticamente significativo y que se correlacionó de forma positiva con su efecto analgésico en las áreas terminales corticales fronto-parietal externa (+64%, interna (+69% y piriforme (+113%, las regiones del hipocampo CA1 (+111% y DGm (+60%, los núcleos amigdalinos PMCo (+101% y AHiAL (+91% y el hipotálamo (+127%.

    Full Text Available O óxido nítrico atua como neurotransmissor não adrenérgico e não colinérgico na bexiga e na uretra. Sua forma de ação se faz pela ativação da guanilatociclase responsável pela transformação de GMP em GMPc que promove o relaxamento da fibra muscular lisa. O citrato de sildenafil causa aumento do GMPc, através da inibição de fosfodiesterases, que hidrolisam o GMPc. Assim, o objetivo do experimento foi verificar sua ação na uretra. MÉTODOS: Estudou-se 6 ratas com peso aproximado de 200g. A anestesia foi com uretana na dose de 1,25 mg/kg. As cistometrias, em número de 3, foram realizadas através de cistostomia com cateter P50. A primeira logo após a cistostomia; a segunda depois da desnervação cirúrgica da bexiga e a terceira uma hora após a infusão gástrica do citrato de sildenafil. O sistema de registro das pressões constou de uma bomba de infusão contínua regulada para 0,3ml/minuto conectada em Y com o cateter P50 e a um polígrafo Narco-Bioystem. Nas cistometrias avaliou-se as pressões vesicais máxima e mínima nos momentos: normais-(I; desnervadas (II e desnervadas com citrato de sildenafil na dose de 1 mg/kg (III.

    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.

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

    2002-02-15

    Pain, a major symptom of stomatological disease, usually leads to a specialist consultation. Most commonly it is caused by dental caries and differs in nature and in intensity according to the stage of disease: dentinitis, pulpitis, desmodontitis and dental abscess. Added to this is peridental pain and the pre- and post-operative pains related to these diseases. Almost all oral-maxillary pathology is painful, be it boney such as in osteomyelitis and fractures, mucosal in gingivo-stomatitis and aphthous ulcers, or tumourous. However, besides the "multidisciplinary" facial pains such as facial neuralgia and vascular pain, two pain syndromes are specific to stomatology: pain of the tempero-mandibular joint associated with problems of the bite and glossodynia, a very common somatic expression of psychological problems.

    OC (oral contraception) includes the combined and sequential methods, postcoital and progestin only contraception, mini pills, and macro pills. The mechanism of action of OC modifies the hypothalamo-hypophysary secretion, the uterine mucosa, and the cervical mucus. Effectiveness of OC is nearly 100%; prescription of OC requires a complete clinical and biological evaluation of the patient. Contraindications to OC are any form of cancer, hypertension, vascular or thrombotic antecedents, obesity, tabagism, diabetes. OC users must be checked at least every 6 months, and treatment can last, if there are no evident signs of side effects, until about age 40. The most commonly known side effects of OC are menstruation disorders, cardio- and cerebrovascular effects, hepatic and metabolic effects; there is no evidence that OC can cause carcinogenic effects, but it can increase teratogenic risk. The association of OC with such drugs as Rifampicine, anticonvulsants and/or tranquillizers, can nullify contraceptive effectiveness. PMID:6900393

Remember that asymptomatic HSV-1 shedding in saliva may result in an oral-genital transmission. Perform an anogenital examination and a screening for other sexually transmitted diseases when oral warts are diagnosed. Search for immunosuppression and monitor the patient (screening for a potential associated carcinoma) when there is rapid growth of oral warts. Consider all the clinical signs (systemic, skin, other mucosa, immunity...) when a patient has an enanthem or oral ulcerations.

O procedimento a 80 ºC (DCB80 extraiu aproximadamente 90 % do Fe d na primeira extração e praticamente a totalidade do mesmo na segunda extração, sendo mais efetivo que o procedimento a temperatura ambiente (DCB20, o qual teve sua eficiência reduzida com o aumento da substituição isomórfica de Fe3+ por Al3+ na goethita. A substituição isomórfica de Fe3+ por Al3+ na goethita determinada por DCB80 superestimou os valores determinados por DRX conforme aumentaram as extrações. Em amostras hematíticas, esta estimativa foi prejudicada pela presença de maghemita que dissolveu juntamente com a hematita.Pedogenic iron oxides (Fe d were quantified in 22 hematitic and goethitic soil samples (19 from oxic horizons; one from a plinthic horizon; one from a cambic horizon; one from saprolite by use of two extraction procedures with sodium dithionite-citrate-bicarbonate (DCB. Approximately ninety percent of the Fe d content was extracted at the first extraction by the DCB80 procedure.

    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.

    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

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

    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.

    The pedodontic admission histories of 1600 Mexican children were analyzed, to determine general epidemiologic factors or oral habits, as well as their relationship with identifiable biopsychosociologic factors. Fifty-six percent of the children gave evidence of an oral habit, with significant predisposition among female patients, single children, subjects in poor physical health (particularly from allergies), as well as children with histories of chronic health problems. Oral habits should be considered a major health hazard because of their high incidence. Successful treatment requires a multidisciplinary approach to the basic cause of the problem.

    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.

    Pigmentations are commonly found in the mouth. They represent in various clinical patterns that can range from just physiologic changes to oral manifestations of systemic diseases and malignancies. Color changes in the oral mucosa can be attributed to the deposition of either endogenous or exogenous pigments as a result of various mucosal diseases. The various pigmentations can be in the form of blue/purple vascular lesions, brown melanotic lesions, brown heme-associated lesions, gray/black pigmentations. PMID:26538887

  1. 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.

  2. Melatonin and oral cavity.

    2012-01-01

    While initially the oral cavity was considered to be mainly a source of various bacteria, their toxins and antigens, recent studies showed that it may also be a location of oxidative stress and periodontal inflammation. Accordingly, this paper focuses on the involvement of melatonin in oxidative stress diseases of oral cavity as well as on potential therapeutic implications of melatonin in dental disorders. Melatonin has immunomodulatory and antioxidant activities, stimulates the proliferation of collagen and osseous tissue, and acts as a protector against cellular degeneration associated with aging and toxin exposure. Arising out of its antioxidant actions, melatonin protects against inflammatory processes and cellular damage caused by the toxic derivates of oxygen. As a result of these actions, melatonin may be useful as a coadjuvant in the treatment of certain conditions of the oral cavity. However, the most important effect of melatonin seems to result from its potent antioxidant, immunomodulatory, protective, and anticancer properties. Thus, melatonin could be used therapeutically for instance, locally, in the oral cavity damage of mechanical, bacterial, fungal, or viral origin, in postsurgical wounds caused by tooth extractions and other oral surgeries. Additionally, it can help bone formation in various autoimmunological disorders such as Sjorgen syndrome, in periodontal diseases, in toxic effects of dental materials, in dental implants, and in oral cancers.

    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.

    We investigated age-26 personality characteristics and age-32 oral health in a prospective study of a complete birth cohort born in Dunedin, New Zealand. Personality was measured using the Multidimensional Personality Questionnaire (MPQ). Oral health was measured using the short-form Oral Health Impact Profile (OHIP-14), a global measure, and dental examinations. Personality profiles were constructed for 916 individuals (50.8% men) using standardized MPQ scores, and multivariate analyses examined their association with oral health. Those reporting 1+ OHIP-14 impacts had higher Negative Emotionality scores (and lower Constraint and Positive Emotionality MPQ superfactor scores) than those who did not. After controlling for gender, clinical status, and the other two MPQ superfactors, those scoring higher on Negative Emotionality had a greater risk of reporting 1+ OHIP-14 impacts, as well as 3+ OHIP-14 impacts and worse-than-average oral health. They also had a greater risk of having lost at least one tooth from caries and of having 3+ decayed surfaces. Personality characteristics appear to shape self-reports of oral health. Personality is also a risk factor for clinical disease status, at least with respect to dental caries and its sequelae. Because the attitudes and values tapped into by personality tests can be altered by brief cognitive interventions, those might be useful in preventive dentistry. PMID:21896053

    2015-10-01

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

    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.

  14. Oral heparin: status review

    2006-05-01

    Full Text Available Abstract Unfractionated heparin and low molecular weight heparin are the most commonly used antithrombotic and thromboprophylactic agents in hospital practice. Extended out-of-hospital treatment is inconvenient in that these agents must be administered parenterally. Current research is directed at development of a safe and effective oral antithrombotic agent as an alternative for the effective, yet difficult to use vitamin K antagonists. A novel drug delivery technology that facilitates transport of drugs across the gastrointestinal epithelium has been harnessed to develop an oral dosage form of unfractionated heparin. Combining unfractionated heparin with the carrier molecule, sodium N-(8 [2-hydroxybenzoyl]amino caprylate, or SNAC has markedly increased the gastrointestinal absorption of this drug. Preclinical and clinical studies to-date suggests that oral heparin-SNAC can confer a clinical efficacious effect; further confirmation is sought in planned clinical trials.

  15. [Oral problems in divers].

    Science.gov (United States)

    Scheper, W A; Lobbezoo, F; Eijkman, M A J

    2005-05-01

    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.

    The incidence of oral cancer is increasing every year. The issues that this epidemic brings are as wide ranging as changes in patient/community education, dental practice systems/ protocols, risk management and investigating new technologies for enhanced detection. The dentist, along with the entire dental team, must continually make every effort to save lives through early detection along with educating patients and our communities about the risk factors for oral cancer. With everyone's efforts, we can stop the growth of this terrible epidemic. PMID:27220177

    2011-01-01

    Full Text Available Oral cancer is one of the major global threats to public health. The development of oral cancer 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 possible to measure the cancer risk of oral premalignancies. Understanding of the biology of oral carcinogenesis will yield important advances for detecting high-risk patients, monitoring preventive interventions, and assessing cancer risk and pharmacogenomics. In addition, novel chemopreventive agents based on molecular mechanisms and targets against oral cancers will be derived from studies using appropriate animal carcinogenesis models. New approaches, such as molecular-targeted agents and agent combinations in high-risk oral individuals, are undoubtedly needed to reduce the devastating worldwide consequences of oral malignancy.

    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

    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.

  17. Social disparity and oral health

    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.

    2015-04-01

    Oral habits, if persist beyond certain developmental age, can pose great harm to the developing teeth, occlusion, and surrounding oral tissues. In the formative years, almost all children engage in some non-nutritive sucking habits. Clinicians, by proper differential diagnosis and thorough understanding of natural growth and developmental processes, should take a decision for intervening. This article describes case series reports of thumb sucking, finger sucking, and tongue thrusting habits, which have been successfully treated by both removable and fixed orthodontic appliances. The cases shown are ranging from the age group of 9-19 years presenting combination of both mixed and permanent dentition development. All cases show satisfactory correction of habits and stable results.

    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

    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

    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.

  9. Antibiotics and oral contraceptives.

    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.

  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

    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

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

    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.

    The reactions of oral V(V/IV) anti-diabetic drugs within the gastrointestinal environment (particularly in the presence of food) are a crucial factor that affects their biological activities, but to date these have been poorly understood. In order to build up reactivity-activity relationships, the first detailed study of the reactivities of typical V-based anti-diabetics, Na3V(V)O4 (A), [V(IV)O(OH2)5](SO4) (B), [V(IV)O(ma)2] (C, ma = maltolato(-)) and (NH4)[V(V)(O)2(dipic)] (D, dipic = pyridine-2,5-dicarboxylato(2-)) with simulated gastrointestinal (GI) media in the presence or absence of food components has been performed by the use of XANES (X-ray absorption near edge structure) spectroscopy. Changes in speciation under conditions that simulate interactions in the GI tract have been discerned using correlations of XANES parameters that were based on a library of model V(V), V(IV), and V(III) complexes for preliminary assessment of the oxidation states and coordination numbers. More detailed speciation analyses were performed using multiple linear regression fits of XANES from the model complexes to XANES obtained from the reaction products from interactions with the GI media. Compounds B and D were relatively stable in the gastric environment (pH ∼ 2) in the absence of food, while C was mostly dissociated, and A was converted to [V10O28](6-). Sequential gastric and intestinal digestion in the absence of food converted A, B and D to poorly absorbed tetrahedral vanadates, while C formed five- or six-coordinate V(V) species where the maltolato ligands were likely to be partially retained. XANES obtained from gastric digestion of A-D in the presence of typical food components converged to that of a mixture of V(IV)-aqua, V(IV)-amino acid and V(III)-aqua complexes. Subsequent intestinal digestion led predominantly to V(IV) complexes that were assigned as citrato or complexes with 2-hydroxyacidato donor groups from other organic compounds, including certain

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

    1989-01-01

    The absorption of naproxen is dependent on the gastric emptying and the dissolution of the drug product in the small intestine. Enteric-coated granules designed to dissolve at pH 5.5 have a delayed absorption profile when given orally. Delivered directly into the duodenum, however, rapid absorption is obtained, indicating that the gastric emptying is the rate-limiting step. By varying the coating layer, it is possible to monitor the dissolution of enteric-coated products within a pH range from 4.5 to 7.0. The onset of absorption can be delayed by increasing the pH resistance of the coating, without affecting the extent of absorption. PMID:2814363

    Oral cancer refers to all malignancies that arise in the oral cavity, lips and pharynx, with 90% of all oral cancers being oral squamous cell carcinoma. Despite the recent treatment advances, oral cancer is reported as having one of the highest mortality ratios amongst other malignancies and this can much be attributed to the late diagnosis of the disease. Saliva has long been tested as a valuable tool for drug monitoring and the diagnosis systemic diseases among which oral cancer. The new em...

  5. Oral melanoacanthoma: A rare case of diffuse oral pigmentation

    Full Text Available The clinical presentation of diffuse pigmentation can be alarming to the patient as well as the clinician. A histopathologic examination of a pigmented lesion is necessary in most of the cases in the oral cavity. Oral melanoacanthoma is a very rare diffuse pigmentation with no specific treatment required. It shows increased number of dendritic melanocytes in an acanthotic epithelium. We present a rare case of diffuse pigmentation in the oral cavity whose diagnosis was done on the basis of clinical presentation and histopathology. Also immunohistochemistry was done.

    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.

    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.

    Ieko, Masahiro

    2015-10-01

    Novel oral anticoagulants (NOACs), a direct thrombin inhibitor (TDI), and direct factor Xa inhibitors (Xa-INHs) have mainly been used for prevention of stroke associated with atrial fibrillation in place of warfarin. DTI obstructs tenase by inhibiting thrombin generated in the initial phase and feedback to the amplification phase of cell-based coagulation reactions. Xa-INHs inhibit factor Xa activity in the prothrombinase complex of the propagation phase. Since the half-life of NOACs is in the approximate range of 8-14 hours, there are peak and trough periods in the blood concentrations of these agents. During the trough period, a small amount of thrombin is generated and plays a physiological role. The antithrombotic effect of NOACs is exerted during the peak period in combination with the effects of physiological coagulation inhibitors (PCIs) such as antithrombin in the trough period. Endothelial cells are the site for action of PCIs, such that it is important that they remain in a good state for effective anticoagulation by NOACs within the lesions. In a meta-analysis of NOACs vs. warfarin treatment, the former significantly reduced stroke or systemic embolic events by 19% as compared with warfarin, due mainly to a reduction in hemorrhagic stroke, while NOAC administration also significantly reduced intracranial hemorrhage by 52%.

    2011-06-01

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

    The FDI has shown considerable interest in the oral cancer and has in recent years arranged three symposia on the subject. The incidence of oral cancer shows marked geographic differences mostly depending upon environmental factors. In the present paper the epidemiology of oral cancer is illustrated by the relative frequency to total number of cancers and incidence rates from a number of countries. Canada has the highest rate of cancer of the vermilion border, which is extremely rare among dark-skinned people. Even within one country differences may be found, a fact which is illustrated by findings from Czechoslovakia and India. In most of the studies dealing with the etiology of oral cancer tobacco usage in its various forms is shown to be the outstanding factor.

    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.

    Oral habits have been described by psychologists and psychyatrists as psychodynamic phenomena. Dentists are concerned with oral habits because of the detrimental consequences they have in the oral facial system. The dentist who is in a position to confront a child with an oral habit in order to treat his dentinofacial problems is required to be aware of the psychological background of his patient as well as of the conditions under which the children do the habit in order to overcome emotional difficulties. The dentist should also search into the child's family to find out what the causes of the child's oral habit maybe. For the treatment of an oral habit the dentist should ensure both the child's and the family's cooperation and he should be aware of the advantages and disadvantages of every available method for treatment. Methods of treatment are: Use of orthodontic appliances: This method has the disadvantage that disturbs the child's psychological need for the habit, it can be interpreted as a punishment, it is visible and it causes speaking difficulties. It should be applied only in cooperation with the child. Behavioristic technique: This method aims to reinforce the child's positive behavior according to the Skinnerian principle: stimulus-response-reward. It has fast results but it is a conditioned treatment. Psychoanalytic method: It could solve the problem of the child's primary need for the oral habit in a radical manner. However it is practically impossible to be applied in Dentistry. Behavior modification according to ego psychology. With this method we attempt to analyse and understand the psychological cause of an oral habit.(ABSTRACT TRUNCATED AT 250 WORDS)

    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

    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.

    2013-01-01

    Leukoplakia of the oral mucosa is a potentially malignant disorder, which means that there is an elevated risk oftransformation into a squamous cell carcinoma. The term oral leukoplakia is a clinical diagnosis for a predominantly white lesion which is not immediately recognizable as another well definable lesion which is white in appearance. Oral leukoplakia is generally an asymptomatic disorder of the mucosa with a prevalence of less than 2 per cent in the adult population. Tobacco usage is considered to be the most important etiological factor. Malignant transformation into a squamous cell carcinoma occurs in about I per cent per year. A patient with oral leukoplakia is generally referred to an oral and maxillofacial surgeon, who takes a biopsy for a definitive histopathological diagnosis. The outcome of the histopathological study, which may vary from hyperkeratosis to invasive squamous cell carcinoma, will determine the treatment. It is preferable that every leukoplakia is removed to reduce the risk of malignant transformation. Long term follow-up is indicated. Follow-up may in some cases be performed by the general dental practitioner.

    Oral stereognosis is the ability of the mouth to recognize shape and texture. Oral shape recognition is sensitive to repetition and to topical mucosal anesthesia. Age, upper and lower arch perimeter, and labiolingual dysfunction also interact with oral stereognosis. The purpose of this investigation was to define the influence of age, arch size, and oral dysfunction on oral stereognosis when submitted to repeated trials. Fifty subjects were selected before orthodontic treatment. Each subject underwent 4 trials: T1 and T4 without anesthesia and strictly similar, T2 with topical anesthesia of the tongue, and T3 with topical anesthesia of the palate. Five test pieces or stimuli were used. The recognition time (RT) of each stimulus, the perimeter of upper and lower anterior dental arch, and the labiolingual dysfunction index (LLDI) were the main variables statistically evaluated. Subjects with a mild degree of dysfunction needed more time to recognize the stimuli in T3 when compared with T2. The number of RT3 > RT2 was 2.5 +/- 1.12 in the group with a low LLDI (12 +/- 1.5), and 1.57 +/- 0.63 in the group with an LLDI of 16 +/- 2.5 (P >.05). This may be attributed to different manipulation of the test pieces between the 2 groups, which could have been modified through sensory deprivation. Bolus recognition before the swallowing act needs to be paralleled to stereognostic performance.

    White lesions of the oral mucosa may be due to highly diverse disorders. Most of these disorders are benign but some may be a malignant or premalignant condition. The disease is often confined to the oral mucosa. There are also disorders which are accompanied by skin disorders or systemic diseases. Many white oral mucosa disorders have such characteristic clinical aspects that a diagnosis can be made on clinical grounds only. When the clinical diagnosis is not clear, histopathological examination is carried out. Treatment depends on the histological diagnosis. In some cases, treatment is not necessary while in other cases, treatment is not possible since an effective treatment is not available. Potentially malignant disorders are treated.

    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.

    Oral diseases, including dental caries, periodontal disease, and tooth loss, affect the majority of the population and can affect a person's overall health. Raisins contain polyphenols, flavonoids, and high levels of iron that may benefit human health. However, their oral health benefits are less well understood. We hypothesized that raisins contain antimicrobial phytochemicals capable of suppressing oral pathogens associated with caries or periodontal diseases and thus benefit oral health. Through antimicrobial assay-guided fractionation and purification, compounds identified with growth inhibition against oral pathogens were oleanolic acid, oleanolic aldehyde, linoleic acid, linolenic acid, betulin, betulinic acid, 5-(hydroxymethyl)-2-furfural, rutin, beta-sitosterol, and beta-sitosterol glucoside. Oleanolic acid suppressed in vitro adherence of cariogenic Streptococcus mutans biofilm. When the effect of raisins and raisin-containing bran cereal on in vivo plaque acidogenicity was examined in 7- to 11-y-old children, it was found that raisins did not reduce the plaque pH decline below pH 6 over the 30-min test period. Compared with commercial bran flakes or raisin bran cereal, a lower plaque pH drop was noted in children who consumed a raisin and bran flake mixture when no sugar was added (P < 0.05). Grape seed extract, high in proanthocyanidins, positively affected the in vitro demineralization and/or remineralization processes of artificial root caries lesions, suggesting its potential as a promising natural agent for noninvasive root caries therapy. Raisins represent a healthy alternative to the commonly consumed sugary snack foods.

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

    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.

  2. Epigenetic Disregulation in Oral Cancer

    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.

  7. [Oral candidiasis: clinical features and control].

    Science.gov (United States)

    Yamamoto, Tetsuya

    2010-10-01

    Candidiasis is the most commonly encountered fungal infection, and oral candidiasis is often observed as a local opportunistic infection. Oral candidiasis is clinically divided into three types: acute forms, chronic forms, and Candida-associated lesions. Candida adhesion and multiplication are largely regulated by the local and systemic factors of the host. The local factors include impairment of the oral mucosal integrity, which is usually impaired by hyposalivation, anticancer drugs/radiation for head and neck cancers, denture wearing, a decrease in the oral bacterial population, and poor oral hygiene. Among Candida species, oral candidiasis is mostly caused by Candida albicans (C. albicans), C. glabrata, or C. tropicalis. Oral Candida induces a variety of symptoms, such as oral mucosal inflammation manifesting as an uncomfortable feeling, pain, erythema, erosion, taste abnormalities, and hyperplasia of the oral mucosa. Candida overgrowth in the oral cavity may disseminate to distant organs. Therefore, in order to avoid the sequelae of systemic candidiasis, oral candidiasis should be rapidly controlled. Oral candidiasis is usually treated by the local application of antifungal drugs. However, oral candidiasis occasionally escapes the control of such local treatment due to the development of multi-drug resistant Candida strains and species or due to the suppression of salivation or cellular immune activity. When drug-resistant strains are suspected as the pathogens and when the host is generally compromised, the oral administration of combinations of antifungal drugs, enhancement of cellular immune activity, and improvement of the nutritional condition are recommended.

    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.

    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.

    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.

    Full Text Available Paracoccidioidomycosis (PCM is a deep mycosis with primary lung manifestations that may present cutaneous and oral lesions. Oral lesions mimic other infectious diseases or even squamous cell carcinoma, clinically and microscopically. Sometimes, the dentist is the first to detect the disease, because lung lesions are asymptomatic, or even misdiagnosed. An unusual case of PCM with 5 months of evolution presenting pulmonary, oral, and cutaneous lesions that was diagnosed by the dentist based on oral lesions is presented and discussed.

    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 immedi...

    2010-01-01

    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.

    1999-04-01

    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

    Full Text Available Body piercing indicates the puncturing of a part of the body in which jewelry may be worn. In recent years, oral piercing is increasingly popular especially among young people. Body piercing has to be considered as a surgical procedure to all intents and purposes and, as such, has to be performed only by qualified personnel able to assure high standards of professionalism in facilities subject to sanitary inspections.The aim of the present work is to verify what risks patients may be exposed to and what complications may occur after a healthcare professional performs oral piercing.Our retrospective study includes 108 patients (74 males and 34 females aged between 14 and 39 years, who had oral piercing done 12±4 months earlier. All the patients underwent clinical examination to reveal the possible presence of late complications. After piercing, none of the 108 patients developed widespread complications.Although all patients said they had followed the piercers' instructions, 96% of them reported postoperative local complications such as bleeding within 12 hours of piercing (90%, perilesional edema for 3±2 days after piercing surgery (80%, and persistent mucosal atrophy (70%.

    Despite the common prevalence of cutaneous psoriasis, the existence of manifestations in the oral cavity is subject to controversy. In this article, dermatologic psoriasis is reviewed, and a patient with generalized, symptomatic oral mucosal erythema resembling atrophic candidiasis synchronous with flare of chronic skin psoriasis is described. Diagnostic work up and therapeutic response supported that these mucosal findings were the oral counterpart of cutaneous disease. Dental providers should be familiar with the signs and symptoms of oral psoriasis, institute appropriate preventive measures, and provide palliation directed at symptomatic oral changes of psoriasis.

    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

Methods The subjects constituted a randomised sample from the 1992 data collection in the Prospective Population Study of Women in Gothenburg, Sweden (n = 999, 38- > =78 yrs. The study comprised a clinical and radiographic examination, together with a self-administered questionnaire. Obesity was defined as body mass index (BMI > =30 kg/m2, waist-hip ratio (WHR > =0.80, and waist circumference >0.88 m. Associations were estimated using logistic regression including adjustments for possible confounders. Results The mean BMI value was 25.96 kg/m2, the mean WHR 0.83, and the mean waist circumference 0.83 m. The number of teeth, the number of restored teeth, xerostomia, dental visiting habits and self-perceived health were associated with both total and central adiposity, independent of age and SES. For instance, there were statistically significant associations between a small number of teeth ( Conclusions Associations were found between oral health and obesity.

    2013-10-01

    To date, the term oral leukoplakia (OL) should be used to recognize 'predominantly white plaques of questionable risk, having excluded (other) known diseases or disorders that carry no increased risk of cancer'. In this review, we addressed four controversial topics regarding oral leukoplakias (OLs): (i) Do tobacco and alcohol cause OLs?, (ii) What percentage of OLs transform into oral squamous cell carcinoma (OSCC)?, (iii) Can we distinguish between premalignant and innocent OLs?, and (iv) Is proliferative verrucous leukoplakia (PVL) a specific entity or just a form of multifocal leukoplakia? Results of extensive literature search suggest that (i) no definitive evidence for direct causal relationship between smoked tobacco and alcohol as causative factors of OLs, (ii and iii) the vast majority of OLs follow a benign course and do not progress into a cancer, and no widely accepted and/or validated clinical and/or biological factors can predict malignant transformation, and (iv) the distinction between multifocal/multiple leukoplakias and PVL in their early presentation is impossible; the temporal clinical progression and the high rate of recurrences and development of cancer of PVL are the most reliable features for diagnosis.

    Bogousslavsky, J; Dizerens, K; Regli, F; Despland, P A

    1991-06-01

    Perioral and distal upper limb sensory dysfunction (cheiro-oral syndrome) has classically been attributed to cortical involvement. In previously reported cases of the syndrome, caused by stroke, however, the thalamus or brain stem has been the actual site of the lesion. We have studied two patients with infarct in the superficial middle cerebral artery territory involving the parietal operculum. Sensory involvement was purely subjective in the face, but severe hypoesthesia was present in the distal upper limb, involving mainly position sense, stereognosis, and graphesthesia. Temperature and pain sensation were involved in one patient. These findings correlated with involvement of the lower part of the postcentral gyrus, more caudal parts of the parietal operculum, and underlying white matter. This opercular cheiro-oral syndrome seems more uncommon than faciobrachiocrural hemihypesthesia associated with anterior parietal artery territory infarct. A double supply to the parietal opercular region through branches of the temporal arteries and anterior parietal artery may explain the rarity of cheiro-oral syndrome resulting from hemisphere stroke, because simultaneous and partial compromise to two different pial artery networks is uncommon.

Settings and Design: The study was conducted with 1,125 patients who applied to the school of dentistry for routine dental examinations. The authors collect information with a 20-item written questionnaire from the participants about oral cancer risk factors, epidemiology, etiology, and signs and symptoms. Statistical Analysis: Descriptive statistics of demographic variables and other data were reported as means and percentages. Statistical analysis was performed by means of SPSS +11.0 statistical package. 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 total of 140 cases of histologically confirmed oral cancer were evaluated for their demographic details, dietary habits and addiction to tobacco and alcohol using a pre-designed structured questionnaire at the Mahatma Gandhi Institute of Medical Sciences, Sevagram in Central India. These cases were matched with three sets of age and sex matched controls. Oral cancer was predominant in the age group of 50-59 years. Individuals on a non-vegetarian diet appeared to be at greater risk of developing oral cancer. Cases were habituated to consuming hot beverages more frequently and milk less frequently than controls. Consumption of ghutka, a granular form of chewable tobacco and areca nut, was significantly associated with oral cancer cases. Cases had been using oral tobacco for longer duration than controls, and were habituated to sleeping with tobacco quid in their mouth. Most cases were also addicted to smoking tobacco and alcohol consumption. Bidi (a crude cigarette) smoking was most commonly associated with oral cancer. On stratified analysis, a combination of regular smoking and oral tobacco use, as well as a combination of regular alcohol intake and oral tobacco use were significantly associated with oral cancer cases. Synergistic effects of all three or even two of the risk factors - oral tobacco use, smoking and alcohol consumption- was more commonly seen in cases when compared to controls.

    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

    Background: Oral hygiene is intimated in health of all parts of the body including oral cavity. The understanding of actual practices in keeping the oral heath at standard based on patient's perceptions of oral health care is vital. Understanding the effect of gender on oral health would facilitate the development of successful attitude and behavior modification approach towards sustainable oral health. Purpose of Study: To evaluate awareness regarding oral hygiene practices and exploring gender differences among patients attending for oral prophylaxis. Materials and Methods: A survey was conducted among 250 patients attending the department of periodontology, Maulana Azad institute of dental sciences for oral prophylaxis. A structured questionnaire was used to collect information regarding practices and perception about oral hygiene. Results: Majority of the patients (60.4%) felt that oral hygiene is mandatory for overall health of the body. The use of toothpaste and toothbrush (83.6%) was the most preferred cleaning aid among the study population in the present study. The major constraint for avoiding dental examination was no felt need (41.2%) followed by cost of dental treatment (26.8%) and time constraints (24.0%). Conclusions: Professional plaque removal and regular follow-up combined with oral hygiene instructions to the patients can minimize the level of gingival inflammation and swelling. The poor resources for dental care, common malpractices and nonavailability of professional care are the main barriers in seeking optimum oral hygiene. PMID:25024553

    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

    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.

    2015-03-01

    The oral cavity is subject to age related processes such as cellular ageing and immunosenescence. The ageing population bears an increased burden of intraoral pathology. In oral medicine, the majority of presenting patients are in their fifth to seventh decade of life. In this review, we discuss the ageing population's susceptibility to mucosal disorders and the increased prevalence of potentially malignant disorders and oral squamous cell carcinoma, as well as dermatoses including oral lichen planus and immunobullous conditions. We also address the ageing population's susceptibility to oral discomfort and explore salivary secretion, ulceration and the symptoms of oral burning. Finally, we will describe orofacial pain conditions which are more likely encountered in an older population. This update highlights clinical presentations which are more likely to be encountered in the ageing population in a general practice setting and the importance of screening both new and long-term patients.

    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

    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

    Diethyldithiocarbamate (DDC) is known to alleviate acute toxicity due to injection of cadmium salts. However, when cadmium chloride was administered by the oral route, DDC enhanced rather than alleviated the acute toxicity; both oral and intraperitoneal (i.p.) administration of DDC had this effect....... Thus, orally administered DDC enhanced cadmium-induced duodenal and ileal tissue damage and inhibition of peristalsis, as indicated by an increased intestinal transit time. At low cadmium doses, the whole-body retention of cadmium was increased by oral DDC administration. Intraperitoneally administered...

    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.

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.

    Interleukin 37 (IL-37) has been reported to play a significant role in innate immune response and to be involved in several kinds of cancers. However, the investigation of association between IL-37 and oral mucosa carcinogenesis hasn't been clearly established. The aim of the study was to assess IL-37 expression and explore its role in oral mucosa carcinogenesis. The expression of IL-37 increased from normal control (NC) to Oral leukoplakia (OLK) and oral squamous cell carcinoma (OSCC). Moreo...

    Background. Recent studies have demonstrated that podoplanin was expressed in some dysplastic lesions adjacent to primary oral cancers suggesting that podoplanin expression may occur in early oral tumorigenesis and lymphangiogenesis and therefore is related to tumor growth. The purpose of this study is to determine the role of podoplanin as a biomarker for cancer risk assessment in oral leukoplakia and correlation of podoplanin expression with grades of oral squamous cell carcinoma (OSCC).

    Full Text Available Attenuated Salmonella has been used as a carrier for DNA vaccine. However, in vitro and in vivo studies on the bacteria following transfection of plasmid DNA were poorly studied. In this paper, eukaryotic expression plasmids encoding avian influenza virus (AIV subtype H5N1 genes, pcDNA3.1/HA, NA, and NP, were transfected into an attenuated Salmonella enteric typhimurium SV4089. In vitro stability of the transfected plasmids into Salmonella were over 90% after 100 generations. The attenuated Salmonella were able to invade MCF-7 (1.2% and MCF-10A (0.5% human breast cancer cells. Newly hatched specific-pathogen-free (SPF chicks were inoculated once by oral gavage with 109 colony-forming unit (CFU of the attenuated Salmonella. No abnormal clinical signs or deaths were recorded after inoculation. Viable bacteria were detected 3 days after inoculation by plating from spleen, liver, and cecum. Fluorescent in situ hybridization (FISH and polymerase chain reaction (PCR were carried out for confirmation. Salmonella was not detected in blood cultures although serum antibody immune responses to Salmonella O antiserum group D1 factor 1, 9, and 12 antigens were observed in all the inoculated chickens after 7 days up to 35 days. Our results showed that live attenuated S. typhimurium SV4089 harboring pcDNA3.1/HA, NA, and NP may provide a unique alternative as a carrier for DNA oral vaccine in chickens.

    Full Text Available Introduction: It has been daily observed a significant increase ofchemical dependent individuals, as well as the lack of depth on thisissue in the dentistry area. Nevertheless many times the dentalclinicians are the first professionals to diagnose possible alterations,which appear due to the consumption of tobacco, alcohol and other illicit drugs. Objectives: To make a literature review of oral alterations and to identify them on a specific group of persons, which are addicted to different types of drugs. Material and methods: The clinical history of the selected individuals was added to the answers of a questionnaire,comprising the data of the present research. Results: Besides other minor soft tissue alterations, a high prevalence of caries and periodontal diseases were found in the studied population. Conclusion: It was concluded that the role of the dental clinician is very important to the health rehabilitation of drug addicts, individuals with physical and mental disorders that need specific oral care, which sometimes is neglected.

  1. Oral insulin--a perspective.

    2003-01-01

    Diabetes mellitus is generally controlled quite well with the administration of oral medications or by the use of insulin injections. The current practice is the use of one or more doses, intermediate or long acting insulin per day. Oral insulin is a promising yet experimental method providing tight glycemic control for patients with diabetes. A biologically adhesive delivery systems offer important advantage over conventional drug delivery systems. The engineered polymer microspheres made of erodable polymer display strong adhesive interactions with gastrointestinal mucus and cellular lining can traverse both the mucosal epithelium and the follicle associated epithelium covering the lymphoid tissue of Peyer's patches. Alginate, a natural polymer recovered from seaweed is being developed as a nanoparticle for the delivery of insulin without being destroyed in the stomach. Alginate is in fact finding application in biotechnology industry as thickening agent, a gelling agent and a colloid stabilizer. Alginate has in addition, several other properties that have enabled it to be used as a matrix for entrapment and for the delivery of a variety of proteins such as insulin and cells. These properties include: a relatively inert aqueous environment within the matrix; a mild room temperature encapsulation process free of organic solvents; a high gel porosity which allows for high diffusion rates of macromolecules; the ability to control this porosity with simple coating procedures and dissolution and biodegradation of the system under normal physiological conditions.

    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.

    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.

    Full Text Available Objetivos: El afta es la lesión vesiculosa por antonomasia. 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.

    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

    Oral geotrichosis is an uncommon opportunistic infection caused by Geotrichum candidum, a habitual contaminant and component of the flora of various parts of the body. This communication reports both a 20-year retrospective study of clinically and mycologically proven cases of oral geotrichosis, and a prospective study of fungal oral flora in 200 individuals divided into two groups: normal individuals and individuals with associated conditions. Twelve patients with proven oral geotrichosis were included: 9 females and 3 males, with a mean age of 48.5 years; the associated conditions were diabetes mellitus (66.6%), leukemia, Hodgkin's lymphoma and HIV/AIDS infection. The oral geotrichoses showed three clinical varieties: pseudomembranous (75%), hyperplastic, and palatine ulcer. G. candidum was isolated in 11 cases and G. capitatum in one. Positive fungal cultures were obtained from the two groups, and 48% and 78% of cultures were positive, respectively, for Candida spp. In 2.8% and 6.33% of the cases, G. candidum was isolated, respectively, together with one strain of G. capitatum. Oral geotrichosis is an exceptional infection that clinically presents, and is treated, as oral candidiasis. G. candidum may be isolated from the oral flora of a small proportion of patients, either normal individuals or those with associated conditions.

    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.

    2011-01-01

    Tuberculosis is a major cause of morbidity and mortality worldwide. It is a chronic granulomatous disease that can affect any part of the body, including the oral cavity. Oral lesions of tuberculosis, though uncommon, are seen in both the primary and secondary stages of the disease. This article presents a case of tuberculosis of the buccal mucosa, manifesting as non-healing, non-painful ulcer. The diagnosis was confirmed based on histopathology, sputum examination and immunological investigation. The patient underwent anti-tuberculosis therapy and her oral and systemic conditions improved rapidly. Although oral manifestations of tuberculosis are rare, clinicians should include them in the differential diagnosis of various types of oral ulcers. An early diagnosis with prompt treatment can prevent complications and potential contaminations.

    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.

    Dental sleep medicine is a rapidly growing field that is in close and direct interaction with sleep medicine and comprises many aspects of human health. As a result, dentists who encounter sleep health and sleep disorders may work with clinicians from many other disciplines and specialties. The main sleep and oral health issues that are covered in this review are obstructive sleep apnea, chronic mouth breathing, sleep-related gastroesophageal reflux, and sleep bruxism. In addition, edentulism and its impact on sleep disorders are discussed. Improving sleep quality and sleep characteristics, oral health, and oral function involves both pathophysiology and disease management. The multiple interactions between oral health and sleep underscore the need for an interdisciplinary clinical team to manage oral health-related sleep disorders that are commonly seen in dental practice.

    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.

    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.

    Oral biofilms develop under a range of different conditions and different environments. This review will discuss emerging concepts in microbial ecology and how they relate to oral biofilm development and the treatment of oral diseases. Clues to how oral biofilms develop may lie in other complex systems, such as interactions between host and gut microbiota, and even in factors that affect biofilm development on leaf surfaces. Most of the conditions under which oral biofilms develop are tightly linked to the overall health and biology of the host. Advances in molecular techniques have led to a greater appreciation of the diversity of human microbiota, the extent of interactions with the human host, and how that relates to inter-individual variation. As a consequence, plaque development may no longer be thought of as a generic process, but rather as a highly individualized process, which has ramifications for the treatment of the diseases it causes.

    Electrodermal responses in male subjects who gave at least four oral-dependent Rorschach responses (n = 15) or no more than two such responses (n = 19) were assessed both before and after the subjects had either a warm, friendly interaction or a cold, unfriendly interaction with a confederate. There were no group differences on initial baseline measurements. Following a 10-minute warm or cold interaction, there was significant three-way interaction (Period X Condition X Orality) in tonic conductance, p less than .003. Analysis of the three-way interaction produced one simple effect: Highly oral subjects responded differentially to warm or cold treatment by the confederate, p less than .018. Three groups--nonorals in either condition and orals in the condition--increased in physiological arousal over time. Only the highly oral subjects interacting with the warm confederate showed no such increase in arousal, presumably because the presence of a warm, interested other inhibits physiological activation.

    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...

    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.

    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.

    Antithrombotic drug therapy is a main cornerstone - sometimes a fairly uneven cornerstone - of today's clinical practice. Patients treated with antithrombotic drugs appear sometimes unawaited at those of our colleagues, who are not necessarily experts of this narrow field. Furthermore, new and newer molecules of antiplatelet and anticoagulant medicines have come into practice, frequently in combination. This dramatic development has been important to patients; pharmacological - and recently nonpharmacological - antithrombotic treatment has paved the way to improve current modalities in cardiology. Combining elements of the "old four" (heparin, coumadin, aspirin, clopidogrel) have been the basis of any improvement for a long time. Nowadays, there has been an involvement of new drugs, direct oral anticoagulants into practice. It is time now to catch up in using new anticoagulants, regardless of our current speciality in medicine. Orv. Hetil., 2016, 157(38), 1507-1510. PMID:27640616

    Dabigatran is an oral, direct, and competitive inhibitor of thrombin, which is administered to patients with non-valvular atrial fibrillation for prevention of stroke at a dose of 110 mg twice daily or 150 mg twice daily. Anticoagulation by dabigatran is "hybrid anticoagulation", consisting of action of both dabigatran and physiological coagulation inhibitors because warfarin inhibits production of protein C and protein S but dabigatran does not. Management of dabigatran is easier than that of warfarin because food restriction is unnecessary, drug interaction is small, and absorption time is short and serum concentration corresponds to the anticoagulatory effect in dabigatran treatment. The RE-LY trial confirmed effectiveness and safety of both doses of dabigatran for prevention of stroke and both doses of dabigatran had much lower risks of intracranial bleeding compared with warfarin. Compliance to guidance of dabigatran treatment is essential for avoidance of severe hemorrhagic complications. PMID:23631181

    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

    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.

  11. Oral Tolerance: Therapeutic Implications for Autoimmune Diseases

    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.

    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.

    Full Text Available American tegumentary leishmaniasis (ATL can affect the skin or mucosa (mucocutaneous leishmaniasis - MCL including the oral cavity. MCL oral lesions are often confused with other oral diseases, delaying diagnosis and specific treatment, and increasing the likelihood of sequelae. Thus, increasing the knowledge of the evolution of ATL oral lesions can facilitate its early diagnosis improving the prognosis of healing.Evaluate the frequency of ATL oral lesion and describe its clinical, laboratory and therapeutic peculiarities.A descriptive transversal study was carried out, using data from medical records of 206 patients with MCL examined at the outpatient clinics-IPEC-Fiocruz between 1989 and 2013. Proportions were calculated for the categorical variables and the association among them was assessed by the Pearson's chi-square test. Measures of central tendency and dispersion were used for the continuous variables and their differences were assessed by both parametric (t test and non parametric (Mann-Whitney tests. P-values <0.05 were considered as significant.The most affected site was the nose, followed by the mouth, pharynx and larynx. Seventy eight (37.9% have oral lesions and the disease presented a lower median of the evolution time than in other mucous sites as well as an increased time to heal. The presence of oral lesion was associated with: the presence of lesions in the other three mucosal sites; a smaller median of the leishmanin skin test values; a longer healing time of the mucosal lesions; a higher recurrence frequency; and a smaller frequency of treatment finishing and healing. When the oral lesion was isolated, it was associated with an age 20 years lower than when the oral lesion was associated with other mucosal sites.Considering the worst therapy results associated with the presence of oral lesions, we suggest that lesions in this location represent a factor of worse prognosis for MCL.

    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.

  2. Ethical considerations in community oral health.

    2015-05-01

    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

    While the research base is limited, studies have consistently reported poor oral health in elite athletes since the first report from the 1968 Olympic Games. The finding is consistent both across selected samples attending dental clinics at major competitions and more representative sampling of teams and has led to calls from the International Olympic Committee for more accurate data on oral health. Poor oral health is an important issue directly as it can cause pain, negative effects on appearance and psychosocial effects on confidence and quality of life and may have long-term consequences for treatment burden. Self-reported evidence also suggests an impact on training and performance of athletes. There are many potential challenges to the oral health of athletes including nutritional, oral dehydration, exercise-induced immune suppression, lack of awareness, negative health behaviours and lack of prioritisation. However, in theory, oral diseases are preventable by simple interventions with good evidence of efficacy. The consensus statement aims to raise awareness of the issues of oral health in elite sport and recommends strategies for prevention and health promotion in addition to future research strategies.

  4. Oral myiasis in a maxillofacial trauma patient

    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.

    Objectives This study aimed to examine the relationship between self-reported oral health, oral hygiene practices, and oral human papillomavirus (HPV) infection among women at risk for sexually transmitted infections in Ho Chi Minh City, Vietnam. Study design Convenience and referral sampling methods were used in a clinic-based setting to recruit 126 women aged 18–45 years between August–October 2013. Behavioral factors were self-reported. Oral-rinse samples were tested for HPV DNA of two low-risk and 13 high-risk genotypes. Results A higher unadjusted prevalence of oral HPV infection was associated with poorer self-rated overall oral health (p=.001), reporting oral lesions/problems in the past year (p=.001), and reporting a tooth loss not because of injury (p=.001). Higher unadjusted prevalence of oral HPV infection was also associated with two measures of oral hygiene: lower frequencies of toothbrush per day (p=.047) and gargling without toothbrush (p=.037). After adjusting for other factors in multivariable logistic regression models, poorer self-rated overall oral health remained statistically associated with oral HPV infection (p=.042); yet, the frequency of toothbrush per day did not (p=.704). Conclusion Results corroborate the association between self-reported poor oral health and oral HPV infection. The effect of oral hygiene on oral HPV infection remains inconclusive. PMID:26093681

    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.

    2015-07-01

    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.

    Cryotherapy is the deliberate destruction of tissue by application of extreme cold. It is well received by patients due to a relative lack of discomfort, the absence of bleeding and minimal to no scarring after healing. It has many applications in oral medicine and clinical oral pathology, and is extremely usefu in patients for whom surgery is contra-indicated due to either age or medical history. In this paper we outline the principles, mechanisms of action, and current applications of cryotherapy in the treatment of oral lesions, and present some clinical cases. PMID:16669469

  15. Intrinsic differences between oral and skin keratinocytes.

    Directory of Open Access Journals (Sweden)

    Anna Turabelidze

    Full Text Available Keratinocytes cover both the skin and some oral mucosa, but the morphology of each tissue and the behavior of the keratinocytes from these two sites are different. One significant dissimilarity between the two sites is the response to injury. Oral mucosal wounds heal faster and with less inflammation than equivalent cutaneous wounds. We hypothesized that oral and skin keratinocytes might have intrinsic differences at baseline as well as in the response to injury, and that such differences would be reflected in gene expression profiles.

    More than 300 000 new cases worldwide are being diagnosed with oral cancer annually. Complexity of oral cancer renders designing drug targets very difficult. We analyse protein-protein interaction network for the normal and oral cancer tissue and detect crucial changes in the structural properties of the networks in terms of the interactions of the hub proteins and the degree-degree correlations. Further analysis of the spectra of both the networks, while exhibiting universal statistical behaviour, manifest distinction in terms of the zero degeneracy, providing insight to the complexity of the underlying system.

    2012-05-01

    Full Text Available The analysis of the processes of human knowledge transmission, in general, reveal two ways: orality and writing. Traditionally, the scenic phenomenon is observed and analyzed as a variation of orality. With the creation and assertion of disciplines whose objects of study are spectacular practices, like Ethnoscenology, other perspectives have been developed considering, in fact, the particularities and differences between the scenic event and other systems of human expression. Therefore, this paper proposes to analyze scenic aspects regarding the body and its sensory and communication relationships, highlighting them as a different structural format, such as writing and orality.

    Athletes use intravenous (IV) saline in an attempt to maximize rehydration. The diuresis from IV rehydration may be circumvented through the concomitant use of oral glycerol. We examined the effects of rehydrating with differing regimes of oral and IV fluid, with or without oral glycerol, on hydration, urine, and endocrine indices. Nine endurance-trained men were dehydrated by 4% bodyweight, then rehydrated with 150% of the fluid lost via four protocols: (a) oral = oral fluid only; (b) oral glycerol = oral fluid with added glycerol (1.5 g/kg); (c) IV = 50% IV fluid, 50% oral fluid; and (d) IV with oral glycerol = 50% IV fluid, 50% oral fluid with added glycerol (1.5 g/kg), using a randomized, crossover design. They then completed a cycling performance test. Plasma volume restoration was highest in IV with oral glycerol > IV > oral glycerol  > oral. Urine volume was reduced in both IV trials compared with oral. IV and IV with oral glycerol resulted in lower aldosterone levels during rehydration and performance, and lower cortisol levels during rehydration. IV with oral glycerol resulted in the greatest fluid retention. In summary, the IV conditions resulted in greater fluid retention compared with oral and lower levels of fluid regulatory and stress hormones compared with both oral conditions.

  19. Oral contraceptives and liver cancer.

    Science.gov (United States)

    1997-11-01

    To date, nine case-control studies conducted in developed countries have identified an association between oral contraceptives (OCs) and liver cancer. The most recent population-based data from both developed and developing countries failed to confirm such an association, however. A study conducted by the World Health Organization in eight developing countries (Chile, China, Colombia, Israel, Kenya, Nigeria, Philippines, and Thailand), in which 122 women with liver cancer were matched with 802 controls, found no elevated risk for OC users compared with never-users (relative risk, 0.7; 95% confidence interval, 0.4-1.2). This study is particularly significant since it was conducted in countries where hepatitis B virus infection, an important risk factor for primary liver cancer, is widespread. In addition, population mortality data from the US, UK, Japan, and Sweden have failed to document increases in liver cancer cases coincident with increases in OC use. Given that population statistics can detect changes on the magnitude of a 40-50% decrease in the risk of ovarian and endometrial cancer related to OC use, they should be able to detect increases of two to 20 times the risk of liver cancer. The increased risk of liver cancer found in the case-control studies may reflect bias resulting from the small size of these studies. PMID:12348250

    Medical records of patients with a histopathological diagnosis of oral osteoma were reviewed for information on signalment, body weight, history, clinical signs, physical examination and diagnostic imaging findings, surgical procedure performed, and histopathologic characteristics. Clinical signs related to the mass were noted in 2 dogs. One mass was documented to have been present for > 3-years, 3 of the masses were noted on physical examination, and 2 masses were noted during professional scaling and survey intraoral radiographs. All six masses had radiographic signs of bone proliferation without bone lysis. One case had radiographic root resorption of adjacent dentition. Four of the masses were classified as central osteoma and 2 were classified as peripheral osteoma based on clinical and radiographic findings. Four masses were treated with excisional biopsy that consisted of wide excision (rostral maxillectomy) [n = 1] and 3 had marginal excisions (en bloc resection) [n = 3]. Two of the masses were debulked with subsequent biopsy. There was no indication of recurrence in the cases with excisional biopsy and minimal progression in the cases that had lesions debulked > 5.5-months following surgery.

    According to theory, health beliefs are related to health behaviors. We investigated whether individuals who hold favorable oral-health-related beliefs over time have better adult oral health than those who do not. Beliefs about the efficacy of water fluoridation, keeping the mouth clean, avoiding sweet foods, visiting the dentist, using dental floss, and using fluoridated toothpaste were assessed in a birth cohort at ages 15, 18, and 26 years. At each age, the majority of participants endorsed the importance of each practice. However, there was also evidence of instability across time. Individuals who held stable favorable dental beliefs from adolescence through adulthood had fewer teeth missing due to caries, less periodontal disease, better oral hygiene, better self-rated oral health, and more restorations. Dental beliefs can change between adolescence and young adulthood, and these changes are related to oral health. In particular, unfavorable dental health beliefs are related to poorer oral health.

    Considerable human illness can be linked to the development of oral microbiota disequilibria. The predominant oral cavity commensal, Streptococcus salivarius has emerged as an important source of safe and efficacious probiotics, capable of fostering more balanced, health-associated oral microbiota. Strain K12, the prototype S. salivarius probiotic, originally introduced to counter Streptococcus pyogenes infections, now has an expanded repertoire of health-promoting applications. K12 and several more recently proposed S. salivarius probiotics are now being applied to control diverse bacterial consortia infections including otitis media, halitosis and dental caries. Other potential applications include upregulation of immunological defenses against respiratory viral infections and treatment of oral candidosis. An overview of the key steps required for probiotic development is also presented. PMID:23231486

It was concluded that the subjects did not sufficiently understand the dangers of piercing. Medical and dental professionals should warn patients with piercing about potential dangers posed by this current fashion.

  17. [Interactions between oral contraceptives and other drugs].

    Failures of oral contraceptives are possible when combined with rifampicin or antiepileptics, especially phenobarbitone and phenytoin. The mode of action is shown by clinical trials to be due to induction of hepatic enzymes thus increasing the steroid metabolism. Failure or oral contraceptives has occurred with the concomitant use of antibiotics, i.e. ampicillin and sulfonamides. Clinical trials have focused upon the changes in the intestinal flora induced by antibiotics. This might influence the enterohepatic circulation of estrogen and thereby decrease reabsorption of estrogen, but this has not been definitely proved. The failures may be caused by individual pharmacokinetics of oral contraceptives. Oral contraceptives are able to influence the pharmacodynamics of various other drugs metabolized by oxidation or conjugation but besides an increased pharmacological effect of prednisolone and increased toxicity of imipramine the clinical importance is uncertain.

    2013-01-01

    Biofilms play an important role in the development and pathogenesis of many chronic infections. Oral biofilms, more commonly known as dental plaque, are a primary cause of oral diseases including caries, gingivitis, and periodontitis. Oral biofilms are commonly studied as model biofilm systems as they are easily accessible; thus, biofilm research in oral diseases is advanced with details of biofilm formation and bacterial interactions being well elucidated. In contrast, wound research has relatively recently directed attention to the role biofilms have in chronic wounds. This review discusses the biofilms in periodontal disease and chronic wounds with comparisons focusing on biofilm detection, biofilm formation, the immune response to biofilms, bacterial interaction, and quorum sensing. Current treatment modalities used by both fields and future therapies are also discussed.

    Full Text Available Inhalation therapy has been employed as the mainstay of the treatment in chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD. Beta-2 agonists, anticholinergic bronchodilators, inhaled corticosteroids, and sodium cromoglycate are often used alone or in combination in an inhaled form. Studies have shown that inhaled drugs used in the treatment have some adverse effects on the oral health based on their dosage, frequency, and duration of use. Several oral conditions such as xerostomia, dental caries, candidiasis, ulceration, gingivitis, periodontitis, and taste changes have been associated with inhalation therapy. Since the prevalence of chronic respiratory diseases is rising, it is important to provide optimal oral care to the individuals receiving inhalation therapy. This article will review the influence of inhaled drugs on the oral health of individuals and adequate management and prevention of the same.

    2012-01-01

    Probiotics are dietary supplements containing potentially beneficial bacteria or yeasts. Probiotics are live microorganisms thought to be beneficial to the host organism and, when administered in adequate amounts, confer a health benefit on the host. Lactic acid bacteria and bifidobacteria are the most common types of microbes used as probiotics. Probiotics strengthen the immune system to combat allergies, stress, exposure to toxic substances and other diseases. There are reports of beneficial use in HIV infections and cancers.These products help in stimulating oral health promoting flora, and suppress the pathologic colonization and disease spread. Probiotics can be bacteria, molds and yeast, but most probiotics are bacteria. In recent years, there has been a lot of interest in the use of probiotics in maintaining good oral health and treating oral infections. Their use in premalignant and malignant oral disorders is yet to be probed.

    Objective To determine the utility of oral fluids for assessment of coronary and cardiovascular (CVD) health. Study Design Twenty-nine patients with pre-existing CVD disease underwent an invasive cardiac procedure (alcohol septal ablation or percutaneous coronary intervention) and provided unstimulated whole saliva (UWS), sublingual swabs (LS), gingival swabs (GS) and serum at 0, 8, 16, 24, 48 hr. Concentrations of 13 relevant biomarkers were determined and correlated with levels in serum and the oral fluids. Results Concentrations of the majority of biomarkers were higher in UWS than LS and GS. Coronary and CVD disease biomarkers in UWS correlated better with serum than LS and GS based on group status and measures of time effect. Seven biomarkers demonstrated time effect changes consistent with serum biomarkers, including C-reactive protein and troponin I. Conclusions Changes in serum biomarker profiles are reflected in oral fluids suggesting that oral fluid biomarkers could aid in the assessment of cardiac ischemia/necrosis. PMID:22769406

  1. Oral Sex and HPV: Population Based Indications.

    2015-03-01

    Human pappilloma virus (HPV) is well established in etiology of uterine cervical cancers, but its role in head and neck cancer is strongly suggested through many epidemiological and laboratory studies. Although HPV-16 induced oropharyngeal cancer is a distinct molecular entity, its role at other sub-sites (oral cavity, larynx, nasopharynx, hypopharynx) is less well established. Oral sex is supposedly the most commonly practiced unnatural sex across the globe and may prove to be a potential transmitting link between cancers of the uterine cervix and the oropharynx in males particularly in those 10-15% non-smokers. In India with the second largest population (higher population density than China) the oral sex is likely to be a common 'recreation-tool' amongst the majority (poor) and with the concurrent highly prevalent bad cervical/oral hygiene the HPV is likely to synergize other carcinogens. Hence in accordance (or coincidently), in India the cervical cancer happens to be the commonest cancer amongst females while oral/oropharyngeal cancer amongst males. Oral sex as a link between these two cancer types, can largely be argued considering a poor level of evidence in the existing literature. The modern world has even commercialized oral sex in the form of flavored condoms. The inadequate world literature currently is of a low level of evidence to conclude such a relationship because no such specific prospective study has been carried out and also due to wide (and unpredictable) variety of sexual practices, such a relationship can only be speculated. This article briefly reviews the existing literature on various modes and population based indications for HPV to be implicated in head and neck cancer with reference to oral sexual practice.

However, in certain susceptible individuals C. albicans can become pathogenic leading to the mucocutaneous infection; oral candidiasis. Murine models and in vitro monolayer cultures have generated some data on the likely virulence and host factors that contribute to oral candidiasis but these models have limitations. Recently, tissue engineered oral mucosal models have been developed to mimic the normal oral mucosa but little information is available on their true representation. In this study, we assessed the histological features of three different tissue engineered oral mucosal models compared to the normal oral mucosa and analysed both cell damage and cytokine release following infection with C. albicans. Models comprised of normal oral keratinocytes and a fibroblast-containing matrix displayed more similar immunohistological and proliferation characteristics to normal mucosa, compared to models composed of an oral carcinoma cell line. Although all models were invaded and damaged by C. albicans in a similar manner, the cytokine response was much more pronounced in models containing normal keratinocytes. These data suggest that models based on normal keratinocytes atop a fibroblast-containing connective tissue will significantly aid in dissecting the molecular pathogenesis of oral candidiasis.
