    Full Text Available La sífilis es una enfermedad infecciosa humana causada por una bacteria: el Treponema pallidum. La enfermedad es transmitida por contacto directo a través de lesiones durante el estadio primario y secundario, por vía transplacentaria intrauterina o a través del canal uterino; puede afectar cualquier órgano de la economía causando un número infinito de presentaciones clínicas. La sífilis secundaria cursa con manifestaciones mucocutáneas características y eventual sintomatología general. La presentación clínica de nuestros dos pacientes es singular ya que solo poseían lesiones en la cavidad oral. La respuesta al tratamiento instaurado fue buena.Syphilis is a human infectious disease caused by the bacterium Treponema pallidum. The disease is transmitted by direct contact with a lesion during the primary or secondary stages, in utero by the transplacental route, or during delivery as the baby passes through an infected canal. The bacterium may infect any organ, causing an infinite number of clinical presentations. Secondary syphilis is characterized by mucocutaneous lesions, a flulike syndrome, and generalized adenopathy. Hepatosplenomegaly may be present. The oral mucosa is the second most frequent site of luetic lesions; the genital areas are the most frequent. In the oral cavity, the most characteristic lesion is a whitish mucosal patch, normally located on the lips, tongue, or palate, which is extremely contagious. The differential diagnosis of this lesion may include oral squamous carcinoma, leukoplakia, candidosis, lichen planus, and hairy oral leukoplakia. Definitive diagnosis is based on clinical information and completed by laboratory examinations even the biopsy can help us. With the diagnosis of secondary syphilis treatment with penicillin G benzathine must be started. We present two cases of secondary syphilis with oral lesions only; the first one, a man with macule covered with a whitish membrane on palate mucosa and a

    Full Text Available El carcinoma fusocelular es una variedad maligna y poco frecuente del carcinoma de células escamosas. Es una tumoración constituida por una doble proliferación celular: una sarcomatosa de células fusocelulares y otra carcinomatosa de células epiteliales. Aunque puede afectar a cualquier parte del organismo, es más frecuente encontrarla en vías aerodigestivas superiores. Afecta con mayor frecuencia a varones entre la 6ª y 7ª décadas de la vida. Tiene un comportamiento agresivo con tendencia a la recurrencia. El alcohol y tabaco han sido identificados como los factores de riesgo más importantes. Su diagnóstico histológico es complicado y muchas veces es necesario recurrir a técnicas de inmunohistoquímica y al uso del microscopio electrónico. En la actualidad, se le atribuye un origen epitelial. El objetivo de este trabajo es presentar una revisión de 9 casos de carcinoma fusocelular localizados en cavidad oral recogidos en nuestro servicio entre los años 1985 a 2004, describiendo su comportamiento clínico y tratando de comprender la patogenia de esta controvertida estirpe tumoral.Spindle cell carcinoma is a malignant and rare variant of squamous cell carcinoma. The histological pattern is composed of a double cell proliferation: a sarcomatous component made up of spindle-shaped cells and a carcinomatous component made up of epithelial cells. Nearly all the anatomy of the body can be affected by these tumors although the most common location is the upper aerodigestive tract. With regard to sex distribution, it is more frequent in males than in females in their sixth and seventh decades of life. Its behavior is aggressive and it tends to recur after treatment. The most important risk factors are alcohol and tobacco. The histological diagnosis is complicated, so immunohistochemical techniques and the use of electron microscopy are usually necessary. Nowadays, its epithelial origin is accepted. The aim of this article is to report a

    Full Text Available A prevalência do papilomavírus humano (HPV na cavidade oral e na orofaringe ainda não está bem esclarecida como nos estudos do trato genital, na qual é bem definida. Entretanto, novas pesquisas estão surgindo após o aparecimento dos exames de biologia molecular. Neste estudo foi realizada uma revisão da literatura com o objetivo de verificar a prevalência do papilomavírus humano na cavidade oral e na orofaringe. Os resultados desta pesquisa mostraram uma prevalência do HPV 16 na mucosa oral normal (infecção latente. Já nas lesões benignas orais associadas ao HPV mostraram uma prevalência do HPV 6 e 11 em papilomas de células escamosas e condilomas, e, nas verrugas, uma prevalência do HPV 2 e 57, enquanto na hiperplasia epitelial focal prevaleceram os HPVs 13 e 32, e no câncer oral, principalmente, no carcinoma de células escamosas (CCE, foi evidenciada uma alta prevalência do HPV 16, o que sugere sua participação na carcinogênese oral, apesar de ser um assunto controverso. Constatou-se também uma enorme discrepância nos resultados da prevalência do papilomavírus humano (HPV na mucosa oral normal (infecção latente e no câncer oral, enquanto nas lesões benignas associadas ao vírus, os resultados foram confirmatórios.The prevalence of human papillomavirus (HPV in the oral cavity and oropharynx has not yet been as well studied as its infection of the vaginal tract.

    Full Text Available Uncaria tomentosa is considered a medicinal plant used over centuries by the peruvian population as an alternative treatment for several diseases. Many microorganisms usually inhabit the human oral cavity and under certain conditions can become etiologic agents of diseases. The aim of the present study was to evaluate the antimicrobial activity of different concentrations of Uncaria tomentosa on different strains of microorganisms isolated from the human oral cavity. Micropulverized Uncaria tomentosa was tested in vitro to determine the minimum inhibitory concentration (MIC on selected microbial strains. The tested strains were oral clinical isolates of Streptococcus mutans, Staphylococcus spp., Candida albicans, Enterobacteriaceae and Pseudomonas aeruginosa. The tested concentrations of Uncaria tomentosa ranged from 0.25-5% in Müeller-Hinton agar. Three percent Uncaria tomentosa inhibited 8% of Enterobacteriaceae isolates, 52% of S. mutans and 96% of Staphylococcus spp. The tested concentrations did not present inhibitory effect on P. aeruginosa and C. albicans. It could be concluded that micropulverized Uncaria tomentosa presented antimicrobial activity on Enterobacteriaceae, S. mutans and Staphylococcus spp. isolates.Uncaria tomentosa é uma planta medicinal usada por vários séculos pela população peruana como alternativa de tratamento para diversas doenças.

    Full Text Available Staphylococcus spp are not usually isolated from the oral cavity, and when this occurs, they are considered to belong to the transitory microbiota. Individuals with periodontal disease represent possible reservoirs of these opportunistic bacteria in the oral cavity. The use of antibiotics for treatment of periodontal disease or other infections may predispose to the increase of the number of Staphylococcus spp. in the oral cavity. These microorganisms easily become resistant to antibiotics, and may result in superinfection. The purpose of this study was to evaluate the presence of Staphylococcus spp. in the oral cavity and in periodontal pockets of patients with chronic periodontitis, identify the isolates and verify the relationship between the presence of Staphylococcus spp. in the oral cavity and presence of periodontal pockets. The study included eighty-eight patients, 25-60 years of age, with chronic periodontitis, and at least two sites with probing depth > 5 mm. Individual data examination was assessed. Then, samples were colleted from the periodontal pocket with the aid of paper tips and from the oral cavity through mouth rinses. Out of the total of patients, 37.50% presented Staphylococcus spp. in the periodontal pocket and 61.36% in the oral cavity, 27.27% presented the bacteria in both sites. S. epidermidis was the most prevalent specie in the periodontal pocket (15.9% and oral cavity (27.27%. The occurrence of higher proportions of nonresident's microorganisms in subgingival samples and oral sites may represent significant problem in causing and maintaining periodontal infections.Staphylococcus spp. não são usualmente isolados a partir da cavidade bucal.

    Full Text Available A matriz extracelular no carcinoma epidermóide da cavidade oral sofre modificações qualitativas e quantitativas durante a sua progressão. Estas alterações parecem possibilitar os processos de invasão e metástase que caracterizam as neoplasias malignas e são mais evidentes na interface tumor-hospedeiro. No nosso estudo, 23 biópsias incisionais de carcinomas epidermóides de diversas localizações da cavidade oral foram classificadas segundo o sistema de graduação histológica preconizado por Anneroth et al.¹ (1987. Foram utilizadas as colorações pela H. E. e a do tipo picrosirius, específica para colágeno. A expressão imuno-histoquímica do colágeno tipo I foi analisada em lesões com diferentes escores histológicos de malignidade. Pôde-se concluir que o colágeno apresenta diferentes padrões morfológicos, histoquímicos e imuno-histoquímicos em lesões com altos e baixos escores de malignidade.An analysis of the extracellular matrix at the invasive front of squamous cell carcinoma of the oral cavity may improve the understanding of tumour cell matrix interactions during malignancy growth. Alterations in collagen I expression may influence cellular invasion and metastasis. In this work, 23 cases of squamous cell carcinoma were submitted to the Anneroth's malignancy grading system¹. H. E. and sirius red staining were used. Immunohistochemical expression of collagen type I protein was observed in different malignancy scores. As a result, it was observed that the extracellular matrix in squamous cell carcinoma of the oral cavity shows different patterns of collagen I expression in low and high scores of malignancy.

    Full Text Available La infección por Papilomavirus Humano (HPV es una de las infecciones virales más difundidas en la población y es considerada una enfermedad de transmisión sexual. La mayoría de estas infecciones son asintomáticas o subclínicas y pasan desapercibidas salvo se haga una prueba molecular para detección del genoma viral en células infectadas. Casi todas las infecciones son transitorias, controladas por la respuesta inmune, sólo algunas se vuelven crónicas o persistentes y éstas son las que tienen mayor potencial oncogénico. Es importante transmitir la necesidad de identificar precozmente las manifestaciones bucales de HPV y valorar la importancia del tratamiento oportuno, lo cual es crucial para mejorar el pronóstico de cáncer bucal.The infection by Human Papillomavirus (HPV is considered a sexually transmitted disease and it is one of the most widespread viral diseases among the general population. Most of these infections are asymptomatic or subclinical and they can remain unnoticed unless the virus could be detected in infected cells by molecular methods. Only some infections are chronic or persistent, and these possess the higher oncogenic potential. It is important to spread the need for early identification of oral manifestations of HPV and to highlight the importance of prompt treatment, which is crucial for improving the prognosis of oral cancer.

    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.

    Full Text Available Cysticercosis is a condition that occurs when man is infested by the larvae of Taenia solium, acting as an intermediate host instead of definitive. Oral cysticercosis is a rare event, and it represents a difficulty in clinical diagnosis. A case of oral cysticercosis in a 23-year-old white female who presented a painless swelling in the dorsal portion of the tongue is reported. An excisional biopsy was performed and histopathological examination revealed a cystic cavity containing the tapeworm.A cisticercose é uma doença que ocorre quando o indivíduo é infectado pela larva da Taenia solium, atuando como hospedeiro intermediário ao invés de definitivo.

Complementary studies involving C. albicans sample isolated from several anatomical sites of immunocompetent or immunocompromised patients (before, during and after specifics therapies and their families or hospital workers must be done in order to establish the sources of C. albicans colonization. The whole-cell proteins profile performed by SDS-PAGE associated with computer-assisted numerical analysis may provide preliminary criteria for taxonomic and epidemiological studies of such microorganisms.O objetivo da presente pesquisa foi analisar os graus de polimorfismos protéicos entre isolados de C. albicans provenientes de diversos sítios anatômicos de quarenta e dois pacientes clínicos, através do emprego da eletroforese em gel de poliacrilamida (SDS-PAGE e análise numérica, a fim de se identificar subespécies e suas similaridades nos diversos nichos infecciosos. Culturas celulares foram desenvolvidas em meio YEPD, coletadas por centrifugação e lavadas com solução salina gelada. As proteínas celulares totais, foram extraídas por rompimento celular, usando pérolas de vidro e submetidas à técnica de SDS-PAGE. Após a eletroforese, as bandas de proteínas foram coradas com coomassie-blue e analisadas pelo conjunto de programas estatístico NTSYS-pc versão 1,70. Matrizes de similaridade e dendrogramas foram gerados pela aplicação do coeficiente de similaridade simple-matching e do algoritmo UPGMA, respectivamente. Os resultados obtidos revelaram vários subtipos de C. albicans e seus graus de similaridade (80% a 100%. Tais dados permitiram demonstrar que, certos pacientes podem estar infectados com dois ou mais subtipos de C. albicans em determinados sítios anatômicos (i.e. apenas na cavidade oral de pacientes imunocomprometidos, sangue ou secreção traqueal, ou ainda, dois ou mais pacientes podem estar infectados em sítios anatômicos idênticos (i.e. apenas em

    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.

    Full Text Available A maioria das doenças dos animais de natureza e cativeiro encontra-se associada à proximidade humana, que resulta da fragmentação e degradação do habitat destes animais, no isolamento das espécies e no contato mais próximo entre estes e animais domésticos e o homem. Foram estudados os sincrânios de 104 mãos-peladas (Procyon cancrivorus por meio de avaliação direta, preenchimento de ficha odontológica veterinária e documentação fotográfica, que relataram anormalidades encontradas, as quais foram classificadas e contabilizadas para fins estatísticos. Os achados deste trabalho aludem que os animais de cativeiro foram mais acometidos com as lesões relacionadas à doença periodontal, como cálculo, reabsorção óssea alveolar, deiscência, fenestração, exposição de furca, além de maloclusão, apinhamento dentário e os níveis mais graves de desgaste dentário. Os animais de vida livre apresentaram mais altos índices de fraturas, perdas dentárias ante-morte e escurecimento dentário, que caracterizam maior trauma dentário, durante o processo alimentar. Pretendeu-se, assim, estabelecer um parâmetro do estado de saúde oral da espécie estudada, sua frequência e se esta apresenta as mesmas enfermidades orais em vida livre e em cativeiro, relacionando a prevalência de afecções orais com características da ecologia da espécie.

    Full Text Available Candida albicans and other species are usually involved in opportunistic infections in patients with acquired immunological deficiency syndrome (AIDS. The virulence mechanisms by which this yeast expresses its pathogenicity include adherence patterns, ability to form pseudomycelia and production of extracellular enzymes, among others. The objective of this research was to verify the frequency of Candida and the production of proteinase and phospholipase in 52 strains of Candida albicans from the oral cavity of patients infected by HIV treated at Hospital São José, AIDS reference and training center in Fortaleza, Ceará. Samples were collected of patients, with or without oral lesions characteristic of candidosis. From 100 patients, 80% presented positivity for Candida: 65% (52 were identified as C. albicans, 27.5% (22 as C. tropicalis, 2.5% (2 as C. glabrata, 2.5% (2 as C. krusei and 2.5% (2 as C. guilliermondii. Among the strains of C. albicans isolated from the oral cavity, proteinase and phospholipase were detected in 69.2% and 73%, respectively. The results suggested that C. albicans was the most frequent species observed, with intermediate expression of proteinase and phospholipase.Candida albicans e outras espécies são usualmente envolvidas em infecções de pacientes com a síndrome da imunodeficiência adquirida (AIDS.

    Full Text Available Leiomioma de cavidade nasal e seios paranasais é raro. Ele constitui menos de 1% de todos os leiomiomas do corpo humano. Isto se deve à escassez de células musculares no nariz. Estas neoplasias podem ser classificadas em três grupos: leiomioma, angiomioma e leiomioma epitelióide. Somente 15 casos de angiomioma foram encontrados na literatura. O tratamento de escolha é a excisão cirúrgica. Um novo caso e a revisão da literatura são apresentados.Liomyomas of the nasal cavity and paranasal sinuses are rare. They make up less than 1% of all leiomyomas in the human body. This is due to the paucity of smooth muscle in the nose. They are classified in three groups: leiomyoma, angiomyoma and epithelioid leiomyoma. Only 15 cases of vascular leiomyomas have been found in the literature. The treatment of choice is surgical excision. Hereby we present a new case and review the literature.

    Full Text Available Phospholipase and proteinase production and the ability of adhesion to buccal epithelial cells (BEC of 112 Candida isolates originated from oral cavity of HIV infected patients and from blood and catheter of intensive care unit patients were investigated. The proteinase production was detected by inoculation into bovine serum albumin (BSA agar and the phospholipase activity was performed using egg yolk emulsion. A yeast suspension of each test strain was incubated with buccal epithelial cells and the number of adherence yeast to epithelial cells was counted. A percentage of 88.1% and 55.9% of Candida albicans and 69.8% and 37.7% of non-albicans Candida isolates produced proteinase and phospholipase, respectively. Non-albicans Candida isolated from catheter were more proteolytic than C. albicans isolates. Blood isolates were more proteolytic than catheter and oral cavity isolates while oral cavity isolates produced more phospholipase than those from blood and catheter. C. albicans isolates from oral cavity and from catheter were more adherent to BEC than non-albicans Candida isolates, but the adhesion was not different among the three sources analyzed. The results indicated differences in the production of phospholipase and proteinase and in the ability of adhesion to BEC among Candida spp. isolates from different sources. This study suggests that the pathogenicity of Candida can be correlated with the infected site.A produção de proteinase e fosfolipase e habilidade de adesão à célula epitelial bucal de 112 isolados de Candida originadas da cavidade bucal de pacientes infectados pelo HIV e de sangue e cateter de pacientes hospitalizados foram investigados.

Poucos casos foram relatados até o momento na literatura, sendo o acometimento, em geral, na cavidade nasal e nos seios maxilares, e menos comumente, na região subglótica. A doença acarreta uma proliferação fibrótica da mucosa nasal com sintomas nasais obstrutivos. Apresentamos o caso de um paciente de 62 anos, sexo masculino, com obstrução nasal de longa data. Ao exame físico apresentava um alargamento importante da porção anterior do septo, com obstrução bilateral da cavidade nasal. O paciente foi submetido a septoplastia e o material obtido do septo foi encaminhado para exame histopatológico, sendo feito o diagnóstico de FAE. O objetivo deste relato de caso é alertar os otorrinolaringologistas sobre esta rara doença, seu diagnóstico diferencial em relação as doenças granulomatosas nasais, seus aspectos histopatológicos e clínicos.Eosinophilic angiocentric fibrosis (EAF is a rare disease which affects the sinonasal tract. A few cases have been reported in the literature affecting the nose and maxillary sinus with even fewer cases in the subglottic area. The disease causes fibrotic proliferation of the nasal mucosa and nasal obstructive symptoms. We present the case of a male patient, 62 years old, with history of nasal obstruction for several years. The clinical examination showed septal enlargement and bilateral nasal obstruction. The patient was submitted to a septoplasty and the septal material was sent for histological examination, which showed the diagnosis of EAF. The aim of this report is to show a rare benign lesion (EAF associated with nasal obstruction, its differential diagnosis with nasal granulomatosis and its histopathological and clinical features.

    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.

Este procedimiento se realiza bajo lupa estereoscópica y permite una visualización directa de los órganos Los mismos se destruyen por medio de una fresa accionada por un torno. De este modo se tiene la certeza de una ablación total. La posterior verificación por mediode cortes histológicos no es por lo tanto necesaria. Esto representa una ventaja importante puesto que las características físicas del hueso de estos animales requieren períodos largos de ablandamiento (generalmente alrededor tres meses. SummaryA surgical procedure for the bilateral ablation of the vomeronasal organs of the armadillo Chaetophractus villosus (Mammalia, Xenarthra is described. The organs are approached from the roof of the oral cavity through a longitudinal slit performed with a dental drill. This procedure is performed under magnifying stereoscopic lens and permits the direct visualization of the organs. Those structures are then destroyed with the dental drill. This provides certainty of totalablation. As a consequence, verification by means of histological sections is not needed. This represents an important advantage since the physical characteristics of the bone of these animals require long periods of softening (usually around three months.

    We evaluated the effectiveness of radiotherapy combined with chemotherapy in patients with oral squamous cell carcinoma. Therefore, 1042 cases where reviewed in School Dentistry - Osaka Univ. Seven hundred and fifteen were male and three hundred and twenty-seven were female. Ora cancer was affected more male than female patients, with mean age of 582 years old. The tongue was the most common anatomic localization of oral cancer. In tongue, the use of external radiotherapy y combined with brachytherapy and brachytherapy isolated presented better results than chemotherapy combined with external radiotherapy. In buccal mucosa, there was not differences in the treatment's results using external radiotherapy and combined chemotherapy and external radiotherapy. In tongue's floor and upper and jaw gingiva the combined treatment with chemotherapy and external radiotherapy presented better results than isolated external radiotherapy. (author)

    Low intensity GaAlAs ({lambda}=830 nm) laser irradiation effects on oral traumatic ulceration were evaluated. For this purpose, twenty patients presenting orthodontic appliance - induced oral traumatic ulceration were randomly distributed in two groups. Patients in group 1 were submitted to the irradiation procedure and group 2 was the control one. The irradiation parameters employed were the following: wavelength 830 nm, one single application of 4 J/cm{sup 2}, punctual in the contact mode and 30 mW power. The control group received the conventional treatment, consisting on topical application of Triancinolon based ointment four times a day. For both groups the agent responsible for the trauma was removed or covered with utility wax whenever removal was impossible. The results were evaluated concerning the wounds size reduction and pain relief. The time of laser irradiation was considered the starting time (time zero) and analysis were done 24 hours, 48 hours and seven days after that. The statistical analysis showed an acceleration in the healing process as well accentuated pain reduction for the irradiated group compared to the control one. These evidences allows us to indicate this protocol of one single application of 4 J/cm{sup 2} as therapy when patients with oral traumatic ulceration can not attend several sessions for a multiple application procedure.

    Full Text Available INTRODUÇÃO: O cisto linfoepitelial oral é uma lesão incomum, assintomática e de pequenas dimensões, geralmente descoberto durante exames de rotina da cavidade bucal. OBJETIVO: Relatar quatro casos de cisto linfoepitelial oral, confrontando seus aspectos com aqueles reportados em outros 119 casos publicados na literatura. RELATO DOS CASOS: Três casos em mulheres, com idade entre 16 e 23 anos, e um caso em homem, com 45 anos, caracterizados por nódulos assintomáticos, de pequenas dimensões e coloração variando do branco ao amarelado. Dois casos estavam localizados na superfície ventral da língua, um em assoalho bucal e outro em orofaringe. Histologicamente, as lesões revelaram cavidade cística contendo quantidade variável de células epiteliais descamadas, revestida por epitélio pavimentoso estratificado, predominantemente paraceratinizado, de interface plana com o tecido conjuntivo. A cápsula fibrosa exibiu um denso infiltrado linfocítico, com identificação de centros germinativos em apenas dois casos. CONCLUSÃO: A análise conjunta dos casos apresentados neste trabalho e de outros 119 casos relatados na literatura revela que os cistos linfoepiteliais orais exibem predileção pelo gênero masculino, com ápice de incidência na terceira década de vida. Em geral, essas lesões se apresentam como pequenos nódulos assintomáticos localizados no assoalho bucal.

Amostras de saliva foram coletadas, diluídas e inoculadas em ágar SB-20 e ágar Sabouraud, respectivamente para Streptococcus do grupo mutans e Candida sp. Previamente à diluição, a saliva concentrada foi analisada, determinando-se os fatores salivares. Após crescimento das colônias, o número de microrganismos foi determinado em UFC/ml. A análise dos resultados permitiu concluir que houve correlação positiva entre os fatores salivares e a presença de microrganismos ilustrada pelo aumento no número de UFC/ml dos microrganismos analisados concomitantemente com a diminuição do fluxo salivar. Os efeitos da radiação comprometeram a homeostasia salivar e favoreceram o aumento das infecções por leveduras e bactérias durante o tratamento radioterápico.The aim of this study was to quantify the microorganisms Streptococcus mutans and Candida sp in the oral cavity of patients with oropharynx carcinoma, before, during and after radiotherapy, and to correlate the results with salivary factors such as pH, buffer capacity (CT and flow rate (FS. Saliva samples were collected, diluted and inoculated in SB-20 agar and in Sabouraud agar, for Streptococcus mutans and Candida sp, respectively. Previously to dilution, the concentrated saliva was analyzed, and the salivary factors were determined. After the growth of colonies, the number of microorganisms was determined in CFU/ml. The analysis of the results allowed to conclude that the salivary factors are related to the presence of microorganisms, and that the number of CFU/ml increased as salivary flow rate decreased.

    Full Text Available Abstract Objectives To determine oral health literacy (REALD-30 and oral health literacy-related outcome associations, and to calculate if oral health literacy-related outcomes are risk indicators for poor self-reported oral health among rural-dwelling Indigenous Australians. Methods 468 participants (aged 17-72 years, 63% female completed a self-report questionnaire. REALD-30 and oral health literacy-related outcome associations were determined through bivariate analysis. Multivariate modelling was used to calculate risk indicators for poor self-reported oral health. Results REALD-30 scores were lower among those who believed teeth should be infrequently brushed, believed cordial was good for teeth, did not own a toothbrush or owned a toothbrush but brushed irregularly. Tooth removal risk indicators included being older, problem-based dental attendance and believing cordial was good for teeth. Poor self-rated oral health risk indicators included being older, healthcare card ownership, difficulty paying dental bills, problem-based dental attendance, believing teeth should be brushed infrequently and irregular brushing. Perceived need for dental care risk indicators included being female and problem-based dental attendance. Perceived gum disease risk indicators included being older and irregular brushing. Feeling uncomfortable about oro-facial appearance risk indicators included problem-based dental attendance and irregular brushing. Food avoidance risk indicators were being female, difficulty paying dental bills, problem-based dental attendance and irregular brushing. Poor oral health-related quality of life risk indicators included difficulty paying dental bills and problem-based dental attendance. Conclusions REALD-30 was significantly associated with oral health literacy-related outcomes. Oral health literacy-related outcomes were risk indicators for each of the poor self-reported oral health domains among this marginalised population.

    Full Text Available Lipoma is a common tumor of soft tissue. Its location on the oral mucosa is rare, representing 1% to 5% of benign oral tumors although it is the most mesenchymal tumor of the trunk and proximal por-tions of extremities. Lipoma of the oral cavity may occur in any region. The buccal mucosa, tongue, and floor of the mouth are among the common locations. The clinical presentation is typically as an asymptomatic yellowish mass. The overlying epithelium is intact, and superficial blood vessels are usually evident over the tumor. Other benign connective tissue lesions such as granular cell tumor, neurofibroma, traumatic fibroma and salivary gland lesions (mucocele and mixed tumor might be included in differential diagnosis. We present two cases of oral lipoma in unusual locations: one in junction of soft and hard palate and the other in tongue. Both were rare in the literature.

  4. Case Report Form for oral health assessments: methodological considerations

    Directory of Open Access Journals (Sweden)

    Joana Christina Carvalho

    2012-01-01

    Full Text Available Information on the oral health condition of the target population is required to enable the development of policy strategies for oral health promotion. This information needs to be substantiated by reliable data obtained through regular oral health assessments. Countries around the world have set up oral health data-registration systems that monitor the oral health of the population. These systems are either integrated in the public oral health care service or in national surveys conducted on a regular basis. This paper describes the conception and development of a Case Report Form for oral health assessments and introduces a recently developed electronic data-registration system for data capture in oral health surveys. The conception and development of a Case Report Form poses a number of challenges to be overcome. In addition to ensuring the scientific quality of its contents, several requirements need to be met. In the framework of national oral health surveys, handwritten data capture has proven accurate, but entails an important workload related to the printing and transporting of the forms, data transfer and storage of the forms, as well as the time required to perform these tasks. On the other hand, electronic data capture enables time saving and better performance. However, the advantages of this system may not be fully acknowledged by general practitioners, and their motivation to employ information and communication technologies may need to be encouraged. In the long term, the inclusion of electronic data registration in university training is probably the best strategy to achieve this.

    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 INTRODUÇÃO: A carcinogênese bucal é um processo multipassos no qual eventos genéticos promovem o rompimento de vias regulatórias normais que controlam funções celulares básicas. O carcinoma epidermóide de cavidade bucal (CECB surge como conseqüência de múltiplos eventos moleculares induzidos pelos efeitos de vários carcinógenos influenciados por fatores ambientais contra um quadro de resistência ou suscetibilidade herdada geneticamente. OBJETIVO: Avaliar a importância clínica e morfológica da imunoexpressão das proteínas p53 e p16 na região do front invasivo de uma série de 35 casos rotineiramente processados de CECB. MATERIAL E MÉTODOS: Amostras de CECB primários tratados exclusivamente por cirurgia foram investigadas. O sistema TNM foi empregado para o estadiamento clínico dos pacientes. Para a gradação morfológica das lesões foi adotado o sistema de gradação do front invasivo. A técnica de imuno-histoquímica foi realizada nas lesões fixadas em formalina tamponada a 10% e emblocadas em parafina para identificação das proteínas p53 e p16. As contagens foram realizadas e submetidas a tratamentos estatísticos específicos. RESULTADOS: As taxas de imunolocalização para as proteínas p53 e p16 foram de 63% e 66%, respectivamente, nas 35 amostras de carcinoma estudadas. Não houve relação entre as expressões das proteínas p53 e p16 com os parâmetros clínico-morfológicos analisados. Não houve correlação entre a expressão imuno-histoquímica das proteínas p53/p16. CONCLUSÃO: A expressão das proteínas p53 e p16 não influenciou os parâmetros clínico-morfológicos analisados neste estudo e aparentemente não representa base molecular para o significado biológico da região do front invasivo tumoral. A ausência de forte correlação entre as expressões imuno-histoquímicas das proteínas p53 e p16 sugere que as mesmas podem participar de atividade biológicas do controle do ciclo celular por

    Full Text Available Primary malignant melanoma is a rare and aggressive neoplasm that originates from the proliferation of melanocytes. Although, it comprises 1.3% of all cancers, malignant melanoma of the oral cavity accounts for only 0.2-8% of all reported melanomas and occurs approximately 4 times more frequently in the oral mucosa of the upper jaw, usually on the palate or alveolar gingivae. Most of the mucosal melanomas are usually asymptomatic in early stages, and presents as pigmented patch or a mass delaying the diagnosis until symptoms of swelling, ulceration, bleeding, or loosening of teeth are noted. The prognosis is extremely poor, especially in advanced stages. Therefore, any pigmented lesion of undetermined origin should always be biopsied. We herewith report of two cases of oral malignant melanoma in a 60 and 75-year-old female.

  12. Oral Manifestations of Inflammatory Bowel Diseases: Two Case Reports

    Pereira, Manoela Seadi; Munerato, Maria Cristina

    2016-01-01

    Inflammatory bowel diseases (IBD) are known as chronic inflammatory disorders of the digestive tract, represented mainly by Crohn’s disease (CD) and ulcerative colitis (UC). Among the main oral manifestations of IBD are cobblestoning of the oral mucosa, labial swellings with vertical fissures, pyostomatitis vegetans, angular cheilitis, perioral erythema, and glossitis. In this sense, understanding these nosological entities by dentists would help reach early and differential diagnosis. Thus, two case reports are presented and discussed based on theoretical references obtained by a literature review. The first case report refers to an adult patient whose IBD diagnosis was established after stomatological assessment. The second case was a patient with CD diagnosed in childhood with characteristic oral lesions. PMID:26864508

    This review examines the effect of publishing case reports on journal impact factor and future research. All case reports published in the four major English language oral and maxillofacial surgery journals in the two year period, 2007-2008, were searched manually. The citation data of each case report were retrieved from the ISI online database. The number, percentage and mean citations received by case reports and their relation to the 2009 journal impact factor were analysed. Case reports which received more than 5 citations were also identified and all of the citing articles retrieved and analysed. Thirty-one percent of all articles published in major oral and maxillofacial journals in 2007-2008 were case reports. Case reports had a low citation rate with a mean citation of less than 1. There were 38 (7.2%) case reports with more than 5 citations and 30% of the citing articles were also case reports. The publication of case reports negatively affected journal impact factor which correlated directly with the percentage of case reports published within a journal. Case reports reporting recent topics, describing new treatment/diagnosis method and with a literature review were more likely to receive citations.

  14. Evaluation of effects of laser irradiation therapy ({lambda}=830 nm) on oral ulceration induced by fixed orthodontic appliances; Efeito terapeutico da irradiacao com laser de arseneto de galio aluminio ({lambda}=830 nm) em lesoes provocadas pelo aparelho ortodontico fixo na cavidade oral

    Twenty patients presenting fixed orthodontic appliance - induced oral ulceration were randomly chosen for this study. These patients were then divided into two groups. In Group ,1 the ulceration was submitted to low intensity infrared laser ({lambda}=830 nm), at 30 mW fluency per point 1,3 J/cm{sup 2} at an exposure time ranging from 3s to 33s, depending on ulceration size. Ulceration was irradiated on the first day, the process being repeated 24 and then 48 hours later. Evaluations were made seven days after the first irradiation. Group 2 comprised of patients who were exposed to conventional treatment where wax was used to cover the afflicted area. These patients also took triancinolona. Evaluation was made on the same day. In both groups the cause of irritation was eliminated whenever was possible. Clinical results pointed out that the healing process was slightly faster in cases of LILT treated oral ulceration. The latter also presented significant decrease in symptoms of pain. Comparative statistical evaluation results between both groups has shown that in the case of Group 1 patients (those submitted to low-intensity infrared laser beam): 1) Healing process was faster with reduction of sore areas; 2) immediate relief of pain following first irradiation, as stated by patients. Taking into consideration the vast amount of patients who are bearers of fixed orthodontic appliances and whose most usual and frequent complaint is pain and irritation, the use of LILT is highly recommended due to its simplicity and efficacy.

    Oral candidiasis is a significant problem in immune-compromised patients. The most common forms of mucosal candidiasis are oropharyngeal, oesophageal and vaginal, and more than 90% of HIV positive persons will manifest at least one episode of oropharyngeal candidiasis. Local and systemic factors such as uninterrupted daily use of a prosthesis by patients, smoking habit, as well as high glucose intake may contribute to the development of the lesion. The aim of this article is to report an uncommon case of oral candidiasis presenting an aggressive clinical behaviour in a 64-year-old male patient, with a significant smoking habit and a medical history of non-controlled diabetes. The lesion affected the hard and soft palate of the right side, revealing erythematous and ulcerated areas, elevated borders and central portions resembling necrosis, mimicking the clinical features of oral squamous cell carcinoma. However, the correct diagnosis of oral candidiasis was obtained after histopathological and cytological examinations and the patient was easily treated with traditional antifungal drugs and correction of his glucose levels.

    Interaction of natural convection and radiation heat transfer in an open side square cavity has been simulated numerically. Previous studies have shown results of the simulation of heat transfer for convection on this geometry. This paper reports the effect of considering both the convection and the radiation mechanisms. Radiation was found to have a great influence on the total amount of heat lost by the cavity as well as on the pattern of flow and on the temperature field. Computations were performed within the domain of the cavity for two-dimensional laminar flow problem. The average of heat transfer coefficient was calculated for several values of the Grashof number for air (Pr = 0.7), with the bottom wall at 500 K (constant temperature) and the open side at 300 K. [Spanish] Se presenta el estudio de la interaccion conveccion natural-radiacion en una cavidad rectangular abierta. Algunos estudios anteriores han mostrado resultados sobre la transferencia de calor por el mecanismo de conveccion natural sobre cavidades abiertas. Aqui se presenta la influencia de considerar ambos mecanismos de transferencia de calor, la conveccion y la radiacion. Se demuestra que el intercambio radiactivo tiene una gran influencia tanto en la cantidad total de calor perdido por la cavidad al ambiente, como en el patron de flujo y de temperatura dentro de la cavidad. Se resuelven numericamente las ecuaciones gobernantes para flujo laminar en dos dimensiones y se calcula el coeficiente promedio de transferencia de calor para diferentes valores del Grashof en una cavidad llena de aire (Pr 0.7), teniendo la pared del fondo de la cavidad a 500 K y los alrededores a 300 K.

    Full Text Available Snus (nass is a form of snuff used in a similar manner to American dipping tobacco, but it does not typically result in a need for spitting. Possible hazards associated with this material include malignant and premalignant lesions in the oral cavity and gastrointestinal tract. The use of smokeless tobacco has increased in the Middle East in recent decades, particularly among teenagers and young adults. Therefore, practitioners must be able to recognize malignant and premalignant lesions. Although, an estimated 10-25% of the world′s population uses smokeless tobacco, this practice is virtually unknown in Iran. The aim of this study is to report a series of cases of squamous cell carcinoma and verrucous carcinoma occurring in the users of snus, who referred to the Department of Oral Medicine in Kerman Dental School.

    Pemphigus vulgaris (PV) is a chronic, autoimmune, intraepidermal blistering disease of the skin and mucous membranes. The initial clinical manifestation is frequently the development of intraoral lesions, and later, the lesions involve the other mucous membranes and skin. The etiology of this disease still remains obscure although the presence of autoantibodies is consistent with an autoimmune disease. These antibodies are targeted against the adhesion proteins of keratinocytes, leading to acantholysis (disruption of spinous layer, leading to intraepidermal clefting) and blister formation. Because only oral lesions are present initially, the chances of misdiagnosing the disease as another condition are increased, leading to inappropriate therapy. In this article, we report a case of PV with only oral manifestations in a 36-year-old male. PMID:27721634

  3. Large oral lipoma: Case report and literature review in Iran

    Full Text Available Lipoma is a benign mesenchymal tumor of fat with uncertain pathogenesis. Although the most common mesenchymal neoplasm in trunk and proximal portions of the extremities, it is rarely seen in the oral cavity. Oral lipomas are clinically soft, smooth-surfaced nodular masses that mostly are less than 3 cm in size. Typically the tumor is asymptomatic unless bitten or become noticeable because of their size. The buccal mucosa and buccal vestibule are the most common intraoral sites and account for 50% of all cases. Reported here is a relatively large lipoma of buccal mucosa that was treated surgically under local anesthesia. In an 18-month postsurgical follow up no complication or recurrence has occurred. This case will also be compared to intraoral lipomas reported in Iranian population. As lipomas are usually smaller than 3 cm in diameter, lipoma with the size reported, is of clinical importance. Since the large lipomas are in differential diagnosis with other, even malignant, mesenchymal, or salivary gland tumors. Thus, this case report recommends clinical awareness in diagnosis of large intraoral soft tissue lesions.

    Full Text Available Angioleiomyomas are benign mesenchymal tumors derived from smooth muscle, which rarely occur in the oral cavity. We report a case of an angioleiomyoma occurring in the maxillary gingiva. The lesion was painless, with a lobulated surface, fibrous in consistency, and firm upon palpation. Microscopic examination showed an encapsulated tumor mass composed of large vascular channels of varying calibers, surrounded by thick walls of irregularly arranged, spindle-shaped cells, which were immunopositive for smooth-muscle actin. It is sometimes difficult to differentiate an angioleiomyoma from other spindle-cell tumors, thus we emphasize its histological differential diagnosis.

    Oral melanoacanthoma (MA) is a rare, benign pigmented lesion, similar to cutaneous MA, characterized by hyperplasia of spinous keratinocytes and dendritic melanocytes. The pathogenesis of oral MA remains uncertain, although its clinical behavior is suggestive of a reactive origin. The most common intraoral sites are the buccal mucosa, lip, palate and gingiva. The average age of presentation is 28 years, mainly in blacks, with a strong female predilection. The oral melanotic macule (MM) is a small, well-circumscribed brown-to-black macule that occurs on the lips and mucous membranes. The etiology is not clear and it may represent a physiologic or reactive process. The average age of presentation is 43 years, with a female predilection. A biopsy is recommended to distinguish these lesions from each other and from other oral melanocytic lesions. We depict four cases each of oral MA and MM, affecting Caucasian and Latin American mestizo patients. The clinicopathological features of these cases reflect its ample spectrum, and to the best of our knowledge, it is the first example of oral MA affecting a Caucasian boy reported in the English literature. Therefore oral MA and MM should be considered in the differential diagnosis of pigmented lesions in the oral mucosa in these populations.

    A wide variety of lesions may manifest in the oral soft tissues that could be confusing and challenging for the clinicians. These lesions could be as simple as trauma-induced ulcers that need about 2 weeks to heal, to a more complicated situation such as oral cancer. The key points in developing diagnosis and a possible treatment plan may include a comprehensive oral examination, simple understanding of normal oral tissue features, and knowledge of common oral lesions. This will help in the development of a differential diagnosis of the oral lesions/masses based on the risk factors in that particular patient. In this case report, we present a simple oral mass in a patient who had an oral fibroma and lipomas in other areas.

Las características clínicas de esta patología se observan ya en niños muy jóvenes, en la gran mayoría de los casos menores de 5 años de edad. Esta es una patología que puede llevar al óbito, pues revela un compromiso cardíaco importante. Hay señales y síntomas en la cavidad oral en la fase aguda de la enfermedad, como la lengua de "frambuesa", eritema con fisura labial y eritema en la mucosa oral, siendo importante que el dentista tenga el conocimiento de esta patología y encamine el paciente para tratamiento médico con urgencia. Se observó en este caso una característica peculiar, que es la retención prolongada de la dentición temporaria. Una vez diagnosticado y tratado, el conocimiento del Síndrome de Kawasaki permite al dentista planear con seguridad un tratamiento dentario a largo plazo.

    Leiomyomas are bening tumours originated on smooth muscle. The most frequent site of appearance are uterine myometrium, gastrointestinal tract and skin. The highest incidence occurs between 40 and 49 years of age. Its presentation is unusual in children or in older patients. Leiomyomas are unfrequent in the oral cavity, but in this location are usually localized on tongue, lips and palate. Leiomyomas use to appear as well-defined masses, with slow growth and totally asymptomatic. Pain is present just in rare cases. The treatment is surgical escision. Recurrences are extremely unfrequent. The diagnosis is mainly determined by histological studies due to its unspecific clinical appearance. Histopathologically proliferation of smooth muscle cells is observad without necrotic areas. A low number of mitotic figures can be seen. We present the case report of a 25-year old male patient, with a leiomioma on his right retromolar trigone. The low incidence of this pathology, the age of the patient and the unusual location, make the report of the case worthy.

    Full Text Available Abstract Background Dental health is a neglected aspect of adolescent health globally but more so in low-income countries. Secondary analysis using the 2004 Zambia Global School-Based Health Survey (GSHS was conducted in which we estimated frequencies of relevant socio-demographic variables and explored associations between selected explanatory variables and self-reported poor oral hygiene (not cleaning or brushing teeth within the last 30 days of the completion of questionnaire. Findings Most of the 2257 respondents were males (53.9% and went hungry (82.5%. More than 4 in 10 respondents drank alcohol (42.2% while 37.2% smoked cannabis. Overall 10.0% of the respondents reported to have poor oral hygiene. Male respondents were 7% less likely to report to have poor oral hygiene compared to females. Compared to respondents who never drank alcohol, those who drank alcohol were 27% more likely to report to have poor oral hygiene. Respondents who smoked cannabis were 4% more likely to report to have poor oral hygiene compared to those who did not smoke cannabis. Finally, respondents who went hungry were 35% more likely to report to have poor oral hygiene compared to those who did not go hungry. Conclusions Results from this study indicate that female gender, alcohol drinking, cannabis smoking, and going hungry were associated with self-reported poor oral hygiene. The identification of these factors should guide the design and implementation of programs aimed to improve oral health among adolescents.

    Full Text Available Introduction. Epithelioid hemangioma is an uncommon benign vasoproliferative neoplasm that usually manifests as multiple red nodules in middle-aged adults. Case Outline. A 52-year-old male patient presented with a one-year history of a nodular lesion in the left buccal mucosa measuring 3 cm. The clinical hypothesis was lipoma. An excisional biopsy revealed a circumscribed lesion composed of lobules of vessels with perceptible or poor lumina, associated with a prominent inflammatory infiltrate consisting of eosinophils, histiocytes and chronic inflammatory cells. The endothelial cells composing the lesion had an epithelioid morphology and contained abundant eosinophilic cytoplasm. Immunohistochemistry for CD34, factor VIII, collagen IV, alpha-smooth muscle actin, and mast cells, as well as histochemical staining with Weigert’s orcein were performed. Conclusion. Vascular proliferations of soft tissues are a diverse and morphologically complex group of lesions that are difficult to diagnose. This report presents a case of oral epithelioid hemangioma, highlighting relevant morphological and immunohistochemical features that could help distinguish this condition from other neoplasms.

    Full Text Available Introduction: Given growing elderly population and high prevalence of oral and dental diseases in this age group, this study was conducted to investigate oral health status and related quality of life among older adults in Yazd located in central Iran. Methods: The cross sectional study was carried out on 210 elderly people aged ≥ 60 years under the guise of Yazd health care centers who entered the study via cluster random sampling. Oral health was assessed by DMFT index; and self-reported oral and dental health scale was also tested. Further, to measure the oral health-related quality of life, the Geriatric Oral Health Assessment Index was applied. Data were then analyzed by SPSS software through descriptive statistics, t-test, ANOVA, and Pearson correlation coefficient. Results: The mean score of age for the studied population was 67.22 ± 5.62 years. Of whom 60.48 % were women, 79.05 % were married and 42.4% were edentulous. The oral health-related quality of life mean score was 42.46 ± 5.76 (possible rang 12-60 and the DMFT index mean score was 20.33 ± 4.76. The correlation of oral health-related quality of life score with age (r=-0.213, p=0.002 and DMFT index (r= -0.542, p<0.001 was inversely significant. Further, that had a direct significant correlation with self-reported oral health score(r= 0.302, p<0.001. Conclusion: Elderly people's oral health-related quality of life, self-reported oral and dental health status was not desirable. These factors have significant relationships with each other so that increase in DMFT index was associated with decrease in self-reported oral and dental health.

    The aim of this study was to quantify the microorganisms Streptococcus mutans and Candida sp in the oral cavity of patients with oropharynx carcinoma, before, during and after radiotherapy, and to correlate the results with salivary factors such as pH, buffer capacity and flow rate. Saliva samples were collected, diluted and inoculated in SB-20 agar and in Sabouraud agar, for Streptococcus mutans and Candida sp, respectively. Previously to dilution, the concentrated saliva was analyzed, and the salivary factors were determined. After the growth of colonies, the number of microorganisms was determined in CFU/ml. The analysis of the results allowed to conclude that the salivary factors are related to the presence of microorganisms, and that the number of CFU/ml increased as salivary flow rate decreased. The effects of radiation compromised salivary homeostasis and favored the increase of infection by yeasts and bacteria. (author)

    2013-01-01

    Full Text Available Oral squamous papilloma is a benign proliferation of the stratified squamous epithelium, which results in a papillary or verrucous exophytic mass induced by human papilloma virus (HPV. These oral mucosa lesions are most often asymptomatic and have small progression. Laser assisted surgery is common nowadays with several advantages including successful hemostasis, devoid of sutures, wound sterilization and minimal post-operative pain and edema. The aim of this report is to present the oral squamous papilloma in a pediatric patient and its treatment with soft tissue laser. The lesion was excised with diode laser and the healing was uneventful in follow-up visit after one year. Oral squamous papillomas can be found in child′s oral cavity and laser dentistry can be used by dental clinicians to treat these kinds of oral lesions and should be considered as an alternative to conventional surgery.

    Focal epithelial hyperplasia or Heck's disease is an infrequent asymptomatic condition caused by human papillomavirus types 13 or 32 affecting the mucous membrane of the mouth and is commonly seen in young individuals. Firstly, it was described in Indians and Eskimos, but it exists in various populations. We present three cases of Heck's disease in an Afghan immigrant family group living in Iran that seem to have familial predominance. The disease was identified as oral focal epithelial hyperplasia on the basis of histopathologic and clinical findings. The lesions were reduced significantly after 4 months of good oral hygiene. Dentists should be familiar with the clinical manifestations of these types of lesions that affect the oral cavity. In fact, histopathologic assessment and clinical observation are necessary to establish the diagnosis.

    An oral foregut cyst is a rare congenital choristoma lined by the respiratory and/or gastrointestinal epithelium. The exact etiology has not been fully identified, but it is thought to arise from misplaced primitive foregut. This lesion develops asymptomatically but sometimes causes difficulty in swallowing and pronunciation depending on its size. Thus, the first choice of treatment is surgical excision. Surgeons associated with head and neck pathology should include the oral foregut cyst in the differential diagnosis for ranula, dermoid cyst, thyroglossal duct cyst and lymphangioma in cases of pediatric head and neck lesions.

    Lichen sclerosus or lichen sclerosus et atrophicus is a chronic inflammatory disease predominantly affecting the genital mucosa and skin. Clinically, it is characterized by white atrophic plaques in the anogenital region. The lesions are generally asymptomatic, but may cause discomfort with itching and pain. Extragenital mucosal involvement is very unusual, and lesions limited to the oral mucosa are even less frequent. Knowledge of such lesions is important in order to establish a differential diagnosis with other white oral lesions, and histological confirmation is required. We present the case of a 31-year-old woman with a well delimited, pearly white lesion located in the upper gingival mucosa, lip mucosa and adjacent skin. The lesion had led to loss of periodontal attachment of the affected tooth, causing pain in response to tooth brushing. The biopsy confirmed lichen sclerosus, and treatment was provided in the form of intralesional corticoid injections, followed by improvement of the mucosal lesion, though without recovery of the periodontal loss.

    Full Text Available Laser has been used efficiently for treatment of oral lichen planus, leukoplakia, aphthous ulcers and oral manifestations of HIV. Two cases of recalcitrant oral pemphigus vulgaris that were successfully treated with CO 2 laser are described. The patients had been treated by a dermatologist with pulse therapy of methyl prednisolone and cyclophosphamide over a period of 6 to 8 months, but the clinical course was characterized by episodes of painful flare-ups and nonresponsiveness. The patients were extremely uncomfortable with recurrent oral lesions. CO 2 laser at low power was used to irradiate the lesions. It was shown to be effective in relieving pain and healing of lesions, with nonrecurrence. To the best of our knowledge, this is the first case report of such a treatment of oral pemphigus vulgaris. Further clinical studies are warranted to confirm efficacy and to optimize the treatment protocol.

    2015-12-01

    The presence of tooth root remains is a common clinical finding among elderly patients and may reflect a need for treatment. The scope of this study sought to explore the association between the presence of tooth root remains and self-reported oral health among the elderly. Secondary data from two sanitary districts of Porto Alegre, State of Rio Grande do Sul, were analyzed. A conceptual theoretical model was used in the analysis to assess factors related to self-perceived oral health: gender, age, education, marital status, smoking habit, alcohol consumption, demand for oral health care, participation in community groups, family economic self-sufficiency, oral health service accessed, number of teeth and the presence of tooth root remains. The statistical data were analyzed using Chi-square and Poisson Regression tests (95% CI analysis; α 5%). The sample consisted of 849 elderly individuals with a mean age of 69.7 years (± 7.2); 14.5% of the elderly had tooth root remains and 60.7% reported good self-perceived oral health. According to the hierarchical analysis, the absence of tooth root remains was associated with good oral health perception. The qualification and expansion of health care provided should be considered in order to allow planning actions to ensure the maintenance of good oral health for the elderly.

    We describe the presentation and treatment of an HIV-positive patient with an oral ranula, and review the literature. Ranulas are mucoceles or retention cysts formed by the extravasation of mucus from the sublingual gland, presumably due to continued production of saliva in the presence of ductal obstruction. Oral ranulas in children are rare and the overall prevalence of mucoceles has been reported as 0.08% in children aged 0-12 years. However, there has been a documented increased occurrence in HIV-positive patients. This has been attributed to a blockage of the salivary gland by inflammation and peri-ductal fibrosis following HIV-associated salivary gland disease. Oral lesions may indicate infection with HIV and can also predict progression of HIV to AIDS. The most common oral manifestation is oral candidiasis occurring in 67% of children with HIV. Following this salivary gland disease, periodontal and gingival disease and herpes simplex are the next most common. The exact prevalence of ranulas in an HIV population is not known but the occurrence of a paediatric patient with HIV having at least one oral lesion has been documented as high as 63% and salivary gland disease at 50%. The true extent of the relationship between HIV and ranula is as yet unknown. This represents the only reported case of oral ranula in an HIV-positive patient in the UK.

    The krokodil use disorder is an addictive pathology with quite severe organic effects, especially at the skin level, that causes severe and degenerative necrosis of blood and muscle tissue. Though this disorder has a low prevalence in Spain, compared to the large number of consumers in other countries such as Ukraine or Russia, its consumption is slowly but gradually expanding in countries of the European Union and America. The simplicity of the process of obtaining the substance from desomorphine, together with its high availability and low cost, contribute toward consumers' self-sufficiency. This article presents the case of a user of krokodil and reviews the clinical symptoms of oral ingestion.

    Full Text Available Verruciform xanthoma is a benign mucocutaneous, uncommon, nonsymptomatic lesion of uncertain etiopathology, which occurs mostly on the oral mucosa of middle-aged individuals. Histopathologically, VX is diagnosed by presence of lipid-laden foam cells in papillary region of connective tissue. A 60-year-old male patient presented with a painless growth on the left buccal mucosa. On clinical examination a yellowish white exophytic lesion, measuring 11 × 7 mm in size, was found, which was cauliflower-shaped on inspection and painless on palpation. Histopathological examination revealed varying degrees of surface parakeratosis and the accumulation of numerous foam cells in the connective tissue papillae among the uniformly elongated epithelial ridges. On immunohistochemical staining, there was a neutrophilic infiltrate of the epidermis with CD68 positive xanthoma cells restricted to the papillary dermis, mixed with other chronic inflammatory cells.

    Full Text Available Lymphangiomas are vascular malformations, known as benign tumors of lymphatic vessels. They are most commonly located in head and neck region whereas oral cavity lesions are rare. The clinical appearance is either clear fluid and blood filled thin walled blisters or smooth flesh-colored papules or nodules varying in size. The condition does not regress itself. Dilated lymphatic vessels lined with endothelium of varying wall thickness is seen on histopathology. Surgical excision, electrocautery, cryosurgery, radiotherapy, injection of sclerosing agent, CO2 and argon laser are used in treatment and recurrence is common. As a developmental defect lymphangiomas are frequently seen at birth or early childhood period, whereas acquired lymphangioma or lymphangiectasias are structurally and histologically not different from lymphangioma. This condition develops in a previously normal lymphatic vessels and is described following chronic infections as tuberculosis, radiotherapy, cheloid, tumors and recurrent trauma. Thirty six year old female patient with vesicular papules of 9 months history underwent to cryosurgery after the biopsy is compatible with lymphangioma. The lesions are thought to be related to chronic trauma due to deficiency of lower central incisor and dental treatment is offered to patient.

    We report a rare case of a patient who was referred to the Department of Oral medicine in Zagreb, Croatia. The patient was 20 years old, otherwise healthy and not taking any medication. She presented with irregular erosions partially covered with pseudomembranes that involved both lips and retrocomissural mucosa. Discrete erosion was also noticed on her lower lingual gingiva in the area 42. She reported a propolis solution self-medication for treatment of recurrent aphthous ulcers. After ten days of propolis application, lip and oral lesions developed. Patch test to propolis was proven. We highlight the fact that some folk medicine medications, such as propolis, although being known for many decades to be helpful in various conditions, in some individuals might lead to unwanted side-effects due to its antigenic potential. Additionally, every colleague, during the differential diagnosis of the oral lesions must bear in mind unwanted reactions to folk medicine products.

    The aim of this case report is to describe the treatment planning of a young child with severe early childhood caries (S-ECC) as well as the prosthetic rehabilitation technique. A 3-year-old female child was referred to the pediatric dentistry clinic with the chief complaint of tooth pain, difficulty in eating and recurrent hospitalizations caused by dental infections. The mother reported intermittent episodes of fever and recurrent swelling of child's face. The girl presented angular cheilitis and was referred to a dietitian. The treatment plain consisted on a behavior changes in oral hygiene habits, exodontias of all primary teeth and oral rehabilitation with a prosthesis. The extracted teeth with periapical lesions were submitted to histopathologic analysis (hematoxilin and eosin staining) and revealed an inflammatory infiltrate. The aesthetic requirement of children with S-ECC has been a challenge to pediatric dentists. In the present case, the oral rehabilitation provided for the children better aesthetic, nutrition, phonation, and functional conditions.

    ABSTRACT Cysticercosis is a condition in which a human acts as the intermediate host of the pork tapeworm Taenia solium. Although cysticercosis is a common disease in some regions of the world and can occur in any body site, oral lesions are rare. In this report, we document the case of oral cysticercosis in a 10-year-old boy who sought treatment for an asymptomatic nodule on the dorsal surface of the tongue. A detailed history, thorough clinical examination, morphological appearance and the histopathologic findings of the excised cyst formed the basis for the diagnosis of the lesion.

    The aim of the present study was to assess self-reported oral health habits, attitudes, lifestyle between the sample groups of preclinical and clinical dental and technology students in Lithuania using the Hiroshima University Dental Behavioral Inventory (HU-DBI), and to evaluate the impact of education on their behavior and self-reported oral health. A sample of 183 dental and 75 technology students at the Lithuanian University of Health Sciences, Medical Academy, Faculty of Odontology, and Kaunas University of Technology completed the Lithuanian version the HU-DBI questionnaire with 11 additional items. The data were analyzed using the "SPSS 19.0 for Windows" software package. The mean HU-DBI score of clinical final-year dentistry students was significantly higher (p=0.001) than the score of the preclinical group (6.81 (1.2) and 5.96 (1.5), respectively). The mean scores of both groups of dental students were significantly (p<0.05) higher than that of the technology group (5.37 (1.8)). Oral health behaviors and knowledge were superior in dental students. Dental education had a significant positive impact on the oral health and behavior improvement. The attitudes of the Lithuanian dental students should be further improved by initiating a comprehensive program that would emphasize the importance of oral hygiene before the clinical program starts.

    This retrospective observational study investigated the frequency of reporting ethical approval and informed consent in recently published oral and maxillofacial surgery (OMS) research involving human subjects. All research involving human subjects published in the International Journal of Oral and Maxillofacial Surgery, Journal of Oral and Maxillofacial Surgery, British Journal of Oral and Maxillofacial Surgery, and Journal of Cranio-Maxillofacial Surgery during January to June 2005-2007 were analysed for disclosure of ethical approval by a local ethical committee and obtaining informed consent from the subjects. 534 articles were identified; ethical approval was documented in 118 (22%) and individual patient consent in 135 (25%). 355 reports (67%) did not include a statement on ethical approval or informed consent and only 74 reports (14%) disclosed statements of both. Ethical documentation in retrospective and observational studies was scant; 12% of randomised controlled trials and 38% of non-random trials did not report both of ethical protections. Most recent OMS publications involving humans failed to mention ethical review or subjects' consent. Authors must adhere to the international research ethics guidelines and journal instructions, while editors should play a gatekeeper role to protect research participants, uphold scientific integrity and maintain public trust in the experimental process and OMS profession.

    Full Text Available Fetus-in-fetu is a rare condition, less than 200 cases have been reported. Its embryopathogenesis is linked to a monozygotic, diamniotic parasitic twin. The presence of a calcified vertebral column and other body parts are key to the diagnosis, and differentiate it from a teratoma. We report a case of a neonate who was admitted immediately after delivery by Caesarian section following a prolonged obstructed labor caused by a huge mass projecting from the hard palate. The mass had identifiable malformed body parts but was anencephalic. Intraoperative findings were a short stalk and cleft of the soft palate. He had excision of the mass and did well post operatively. Persistent mouth breathing and difficult nasal cannulation lead to request for post operative magnetic resonance imaging which showed patent nostrils and absent residual mass. Prompt and skillful anesthesia and surgical intervention assisted in the survival of this patient.

    Full Text Available En el presente artículo se actualizan los conocimientos sobre actinomicosis y se presenta el caso de un niño con la forma torácica de dicha entidad. La actinomicosis es una infección infrecuente que puede afectar cualquier parte del cuerpo; los Actinomyces son bacilos o filamentos gram positivos que forman parte de la flora endógena de las mucosas en especial las de las cavidades oral e intestinal. Su comportamiento es insidioso pero en oportunidades tiene expresión aguda, fistulización a piel y cicatrización con fibrosis. Los llamados gránulos de azufre son una característica macroscópica del exudado que contribuye al diagnóstico de laboratorio. La infección inicial para la forma cervicofacial suele provenir de la cavidad oral y extenderse a la vecindad o ser aspirada a los pulmones. El tratamiento de elección es la penicilina, inicialmente endovenosa y seguidamente oral por un lapso no menor de 6 meses. Algunas formas requieren manejo quirúrgico. We report the case of a child with thoracic actinomycosis and review this disease. Actinomycosis is a rare infection that can affect any part of the body; Actinomyces are gram positive bacilli or filaments belonging to the endogenous flora of the mUCOUS membranes, specially that of the oral cavity and the intestinal tract. Actinomycosis usually behaves as an insidioUS disease but may ocassionally have acute expressions with fistulization to the skin and fibroUS healing during resolution. The So called sulfur granules are an important macroscopic detail that helps establish the diagnosis. Actinomyces infections usually start in the oral cavity for the cervicofacial form and then spread to contiguous tissues or to the lungs via aspiration. Penicillin is the drug of choice and surgical drainage may become necessary.

    Full Text Available Odontomas are the commonest odontogenic tumors of the oral cavity and are by nature asymptomatic. They consist mainly of dental tissue that may or may not be arranged in an orderly fashion. Their presence is often detected accidentally or due to the presence of a dental disturbance such as an unerupted tooth. The very rarity of odontomas erupting into the oral cavity validates the need for more current literature on the phenomenon. Our report of two cases aims to present and discuss the rare event of an erupting odontoma with the dental community.

    Oral melanoacanthosis (MA) is a rare pigmented mucosal lesion that is considered the counterpart of cutaneous melanoacanthoma. Microscopically the superficial epithelium shows mild to moderate acanthosis, spongiosis and prominent dendritic melanin producing melanocytes, which are present throughout the spinous keratinocytes. Reported cases show predilection for black females and the most common locations in decreasing frequency are buccal mucosa, lip, palate and gingiva. Although its pathogenesis remains uncertain, its clinical behavior is suggestive of a reactive origin. The clinical appearance of oral MA is non diagnostic and therefore biopsy is mandatory to differentiate from other melanocytic lesions, including melanoma.

    Full Text Available Graft-versus-host disease (GVHD is a complication which occurs in an individual who has received allogenic transplant. This was first noticed in individuals who had undergone bone marrow transplantation. Since then it has been described in solid organ transplantation and even transfusion of blood and blood products. Transfusion-associated GVHD (TA-GVHD is acute or chronic in nature. Acute TA-GVHD is rare and usually runs a fulminant and fatal course. In its chronic form, oral cavity is frequently affected with wide variety of signs and symptoms resulting in significant short and long-term complications ranging from mucosal sensitivity and limited oral in take to secondary malignancy and early death.

    Full Text Available Oral submucous fibrosis (OSMF is a chronic, insidious, generalized, and debilitating condition of the oral mucosa predominantly encountered in South-East Asian countries. Oral submucous fibrosis is etiologically linked to the consumption of the areca nut in flavored formulations or as an ingredient in the betel quid chewed by the communities in these countries. The sweet supari, in their multicolored attractive pouches, is the most common chewed product in children. It is considered a harmless mouth freshener and therefore is consumed in larger amount and is kept in the mouth for a longer time and swallowed by the ignorant children. Factors involved in the consumption of sweet supari are levels of awareness, household environment, peer pressure, low cost, easy availability, etc. Here, we report three cases of OSMF in a 9-year-old girl, 13-year-old boy and a 15-year-old girl and literature review.

    2011-10-01

    Full Text Available Pulmonary arterial hypertension is an infrequent but nevertheless serious life-threatening severe complication of HIV infection. It can be treated with bosentan and oral anticoagulants. Bosentan could induce the acenocoumarol metabolism and it increases the INR values. Until now, no study of interaction between bosentan and oral anticoagulants in HIV patients has reported. So we present a case of this interaction between these drugs and we reviewed MEDLINE to identify all the papers published so far. In our case, several weeks after increasing dose of bosentan acenocoumarol dose had to be progressively increased to 70 mg/week (+33% without obtaining an adequate INR level (2.0-3.0. Forty-nine days later, we achieved a therapeutic INR with 90 mg/week of warfarin. The use of bosentan and oral anticoagulants together in these patients require a closer monitoring during first weeks of treatment, after increasing the bosentan dose and even during longer periods of time.

    2010-01-01

    Full Text Available Antiretroviral therapy has changed the course of HIV disease and improved quality of life in HIV patients. Incidence of an oral lichenoid drug reaction induced by zidovudine is not common. Once it occurs, it affects a patient's well being, in particular their oral functions. Here we report the first case of a 34-year-old Thai man with painful erosive lesions involving the lip and buccal mucosa. Treatment with topical fluocinolone acetonide 0.1% alleviated the patient's oral pain, but it was not until the subsequent withdrawal of zidovudine that the patient showed improvement and resolution of the lesions. Long-term follow-up was useful in the management of this patient, and no recurrence of the lesion was found during 21-month follow-up in this patient.

    2008-11-01

    Two HIV infected patients not receiving Highly Active Antiretroviral Treatment (HAART) presented with epidemic Kaposi's sarcoma of the oral cavity. One patient initially refused HAART, but when the lesion became large enough to be noticeable he agreed to HAART associated with excision of the intraoral lesion by CO2 laser. The other patient developed KS and progressed to AIDS at two years after ceasing HAART due to adverse effects; he was referred to hospital for renewed administration of HAART. In both cases, the lesions observed in the oral cavity were the first clinical manifestation of AIDS. These reports underline the close relationship between the use of HAART and the control of KS lesions, highlighting the important role of the dentist in the identification and early diagnosis of these oral lesions.

    Schwannoma is a relatively uncommon, slow-growing benign tumor that is derived apparently from the Schwann cells. The tongue is the most common site, followed by the palate, floor of mouth, buccal mucosa, lips, and jaws. It can present itself at any age. Usually, this lesion is not taken into account during clinical practice and the differential diagnosis includes numerous benign neoformations based on epithelial and connective tissues. Immunohistochemical features can be useful in determining the neural differentiation. Anti-S100 protein is probably the most used antibody to identify this lesion. The schwannoma is usually a solitary lesion, and can be multiple when associated with neurofibromatosis. In the current study, authors report a case of an intraoral schwannoma situated at the vestibule with 20 years of evolution treated by complete surgical excision. The diagnosis was established based on clinical, histopathological, and immunohistochemical aspects. The patient is under clinical control, with no signs of recurrence even after four years.

    Focal epithelial hyperplasia (FEH), or Heck's disease, is a benign proliferative viral infection of the oral mucosa that is related to Human Papil-lomavirus (HPV), mainly subtypes 13 and 32. Although this condition is known to exist in numerous populations and ethnic groups, the reported cases among Caucasians are relatively rare. It presents as asymptomatic papules or nodules on the oral mucosa, gingiva, tongue, and lips. Histopathologically, it is characterized by parakeratosis, epithelial hyperplasia, focal acanthosis, fusion, and horizontal outgrowth of epithelial ridges and the cells named mitozoids. The purpose of this case report was to present 3 cases of focal epithelial hyperplasia in a pediatric age group. Histopathological and clinical features of cases are discussed and DNA sequencing analysis is reported in which HPV 13, HPV 32, and HPV 11 genomes are detected.

    Oral leiomyomatous hamartoma (OLH) is a rare lesion seen in the oral cavity. It mainly presents on the median maxilla and tongue. In the literature in English, there are only 10 reported cases of OLH of the median maxilla. Most of the cases were found in patients of Japanese and Latin American origin. We report a case of OLH in an 18-month-old boy of Middle Eastern ancestry. The lesion presented as a pedunculated, light pink, soft swelling that was located on the labial gingiva of tooth number 21. Microscopically, it showed proliferative smooth-muscle fascicles dispersed in loose fibrous stroma and multiple small vessels. The lesional cells looked mature and elongated and were deeply eosinophilic spindle cells with basophilic, central "cigar-shaped" nuclei. The diagnosis of OLH was supported by positive immunohistochemical reactivity of smooth-muscle actin and desmin. To our knowledge, this is the first reported case of OLH in a Middle Eastern patient.

    Faggion, C M

    2013-03-01

    Dental meetings are one of the most important resources for disseminating knowledge to dental practitioners. Therefore, the information provided in such meetings should be as unbiased as possible. This paper assessed whether major general dentistry and periodontology/implant dentistry meetings have guidelines for reporting scientific evidence in oral lectures and seminars. The homepages of seven dental meetings (EUROPERIO, AAP, EAO, AO, IADR, ADA, and FDI) were assessed to check for guidelines for presenting scientific data in oral lectures and seminars, according to defined criteria. Only three of these dental meetings reported information for presentations on their homepages, although these guidelines were related to technical issues rather than recommendations for the presentation of scientific data. The present paper suggests guidelines for reporting scientific evidence in oral lectures and seminars in dental meetings to improve the current standards of reporting. High standards of reporting may provide less biased information, which is necessary for dental practitioners and clinicians to make accurate judgements on the efficacy/effectiveness of therapies.

    Biorelevant in vitro performance testing of orally administered dosage forms has become an important tool for the assessment of drug product in vivo behavior. An in vitro performance test which mimics the intraluminal performance of an oral dosage form is termed biorelevant. Biorelevant tests have been utilized to decrease the number of in vivo studies required during the drug development process and to mitigate the risk related to in vivo bioequivalence studies. This report reviews the ability of current in vitro performance tests to predict in vivo performance and generate successful in vitro and in vivo correlations for oral dosage forms. It also summarizes efforts to improve the predictability of biorelevant tests. The report is based on the presentations at the 2013 workshop, Biorelevant In Vitro Performance Testing of Orally Administered Dosage Forms, in Washington, DC, sponsored by the FIP Dissolution/Drug Release Focus Group in partnership with the American Association of Pharmaceutical Scientists (AAPS) and a symposium at the AAPS 2012 Annual meeting on the same topic.

    Diamond-Blackfan Anemia (DBA) is a red cell aplasia characterized with physical abnormalities. The incidence of the disease is reported to be five to seven (5–7) cases per million births in Europe and 4–5 per million live births in the UK and Netherlands with equal sex ratio. It was first recognized in 1938 but an exact pathophysiology of the disease has not been described yet. These abnormalities are well known, however, detailed oral and dental conditions related with the disease have not been described previously. We herein presented two cases of DBA together with oral and dental findings. Our study is first to report the gingival status of the patients with a complete investigation of any orthodontic or dental abnormalities in these kind of patients. A careful follow up and preventive therapies should not be missed in these kind of patients. PMID:21769279

    Full Text Available Background:The name ichthyosis is derived from the Greek ikhthus meaning "fish" and refers to the similarity in appearance of the skin to fish scale. The ichthyoses are a heterogeneous group of disorders. There are few studies about the oral manifestations of these disorders. But early reports of ichthyosis in the Indian and Chinese literature date back to several hundred years. Case Presentation:Oral manifestations of the 14-year-old female patient with ichthyosis are presented. Physical examination revealed thick, brownish scales covering the entire body surface including all larger body flexures and corneae. She had short and dry hair. There were no nail abnormalities and hearing loss. Conclusion:We consider that this patient represents a new manifestation of lamellar ichthyosis disease, because congenitally teeth missing and cephalometric analysis measurements have not been reported before.

    Chronic disseminated histiocytosis is a systemic disorder resulting from tumor proliferation of Langerhans-type histiocytic cells. The etiology and pathogenesis are not fully clear, though the clinical manifestations are the result of the accumulation and infiltration of these types of cells in organs and tissues. The present study reports 10 patients (6 boys and 4 girls) with chronic disseminated histiocytosis. The patient age at onset of the disease varied from 4 months to 3.2 years (mean 1.7 years). All patients had oral lesions, and in 5 cases these were the first manifestation of the disease. The most frequent alterations were gingival bleeding (7 cases), aphthae measuring over 1 cm in diameter (6 cases), maxillary osteolytic lesions (6 cases), tooth loss due to expulsive folliculitis (5 cases), oral candidiasis (4 cases), orofacial swelling (3 cases), aphthae measuring under 1 cm in diameter (3 cases), and nonspecific oral pain (2 cases). All the oral lesions disappeared with the treatments prescribed, though some patients developed new outbreaks and exacerbations of the disease.

    Marco Antonio Méndez Sáenz

    2016-12-01

    Full Text Available Heterotopic gastrointestinal cysts of the oral cavity are benign lesions usually discovered during infancy. Their pathogenesis is not very clear. They are rare congenital anomalies that result from remnants of foregut-derived epithelium in the head, neck, thorax or abdomen during embryonic development. The majority of these lesions occur in the anterior ventral surface of the tongue and extend to the floor of the mouth. They are confused clinically by surgeons in cases of head and neck masses in children as ranulas, dermoid and thyroglossal cysts, and lymphangioma. We report the case of a 28-day newborn with a 3.6 cm oval mass on the floor of the mouth causing difficulty eating and cyanosis during crying. Complete surgical excision was performed by an oral approach under general anesthesia. Microscopic examination revealed gastric epithelium with tall columnar mucous cells on the surface and numerous short closed crypts, resembling fundal glands and mature gastric epithelium.

    Plummer-Vinson syndrome (PVS) is a triad of microcytic hypochromic anemia, atrophic glossitis, and esophageal webs or strictures. It is one of the syndromes associated with iron deficiency anemia. Symptoms resulting from anemia predominates the clinical picture, apart from the additional features such as glossitis, angular cheilitis, and dysphagia. Dysphagia is main clinical feature of PVS. PVS carries an increased risk of development of squamous cell carcinoma of esophagus and pharynx. A classic case report of PVS with clinical features, oral manifestations, malignant potential, differential diagnosis, investigation, dental implication, and treatment is discussed here with the literature review from the dentist's point of view. The article carries a message that dental surgeons have to be familiar with the oral manifestations of anemia and be able to suspect PVS to aid in early diagnosis and prompt treatment.

    Venous thromboembolism is a serious, potentially lethal health problem affecting one per 1,000 people annually. Major surgery, the use of oral contraceptives, complicated pregnancy, fractures, and immobilization increase the risk of thrombosis. In addition to these factors, thrombosis is associated with inherited deficiencies of antithrombin III, protein C, and protein S. Together these do not account for more than five to 10% of the cases. Hereditary activated protein C resistance has been recognized as a basis for a majority of cases of familial thrombosis. It accounted for more than a 10 times higher number than that of other known genetic defects. We describe a case of a young female who presented with a pulmonary embolism and was discovered to have activated protein C resistance. This patient had a heterozygous mutation for factor V Leiden and was taking oral contraceptives. This report underlines: 1) increased risk of venous thrombosis in oral contraceptive users who carry factor V Leiden mutation associated with functional resistance to the normal anticoagulation activities of protein C; 2) most episodes occurring in the young are minor, but pulmonary embolus can occur; 3) the importance of identifying other affected members of the family; and 4) the importance of anticoagulation prophylaxis at times of enhanced risk, particularly during pregnancy, postpartum, and major surgery.

El cirujano oral y maxilofacial debe conocer las propiedades biológicas y las características fundamentales de los materiales autólogos, las diferentes técnicas de obtención y sus aplicaciones clínicas. Como zonas donantes se emplean preferentemente las intraorales, el filtro de hueso y los raspadores para pequeños defectos, y el hueso ilíaco, tibia o calota cuando se requiere más cantidad. No existen estudios concluyentes respecto a la asociación de injertos óseos con membranas. La combinación de injertos autólogos con otros materiales de relleno, ha desembocado en múltiples estudios, sin que se puedan establecer conclusiones definitivas por el momento. El hueso autólogo es de elección para el relleno de cavidades óseas, ya que es útil para dar solución a variadas situaciones clínicas de forma simple, rápida y segura.Although a large number of materials have been described for augmenting bone cavities, the best material is still autologous cortical-cancellous bone or bone chip, which can form new bone through osteogenesis, osteoinduction and osteoconduct ion mechanisms.

    Full Text Available A case of chronic bullous type mucocutaneous disease involving oral mucosa was reported from a 56 years old man with never healing oral ulcers and wound on the perianal skin for three years. There were also red and black spots on the limb and back skin and a lesion on nail. Painful oral lesion consisted of mucous erosion, desquamative gingivitis, and sloughing area on palate and tongue. The patient is diabetic. The first perianal skin diagnosis was granulomatous candidasis with differential diagnosis pemphigus vegetates and acuminarum condiloma. However the histopathologic examination did not support these diagnosis. After several histopathologic examinations, the latest perianal skin diagnosis was lichen planus with differential diagnosis granulomatous vasculitis, bowenoid papulosis and pyodema gangrenosum. Other skin diagnosis was erythema multiforme. Oral diagnosis was mucous membrane pemphigoid with differential diagnosis lichen planus, Behçet's syndrome and erythema multiforme. Oral histopathologic examinations showed a sub-epithelial blister, which supported mucous membrane pemphigoid. A lip balm, prednisone 5 mg oral rinse and multivitamins were given but oral improvement started after blood sugar level was controlled. Conclusion: It is not yet known whether skin and oral mucous lesions are from the same disease or not.

    Full Text Available Abstract Background Halitosis represents a common dental condition, although sufferers are often not conscious of it. The aim of this study was to examine behavior in a sample of Italian subjects with reference to self-reported halitosis and emotional state, and specifically the presence of dental anxiety. Methods The study was performed on Italian subjects (N = 1052; range 15-65 years. A self-report questionnaire was used to detect self-reported halitosis and other variables possibly linked to it (sociodemographic data, medical and dental history, oral hygiene, and others, and a dental anxiety scale (DAS divided into two subscales that explore a patient's dental anxiety and dental anxiety concerning dentist-patient relations. Associations between self-reported halitosis and the abovementioned variables were examined using multiple logistic regression analysis. Correlations between the two groups, with self-perceived halitosis and without, were also investigated with dental anxiety and with the importance attributed to one's own mouth and that of others. Results The rate of self-reported halitosis was 19.39%. The factors linked with halitosis were: anxiety regarding dentist patient relations (relational dental anxiety (OR = 1.04, CI = 1.01-1.07, alcohol consumption (OR = 0.47, CI = 0.34-0.66, gum diseases (OR = 0.39, CI = 0.27-0.55, age > 30 years (OR = 1.01, CI = 1.00-1.02, female gender (OR = 0.71, CI = 0.51-0.98, poor oral hygiene (OR = 0.65, CI = 0.43-0.98, general anxiety (OR = 0.66, CI = 0.49-0.90, and urinary system pathologies (OR = 0.46, CI = 0.30-0.70. Other findings emerged concerning average differences between subjects with or without self-perceived halitosis, dental anxiety and the importance attributed to one's own mouth and that of others. Conclusions Halitosis requires professional care not only by dentists, but also psychological support as it is a problem that leads to avoidance behaviors and thereby limits relationships. It

If intolerable AE of oral MTX persist, switching from oral to subcutaneous (SC) or intramuscular (IM) administration...... is common. However, this approach is largely empirical and the evidence is inconsistent. To our knowledge, this will be the first study to estimate the change in GI AE of switching from oral to SC MTX. METHODS: A retrospective postal survey was sent to patients who had changed from oral MTX to SC MTX. GI AE...... was rated by visual analogue scale (VAS) regarding frequency and intensity of nausea, frequency of vomiting and frequency of discomfort. All participants gave informed consent. No further ethical clearance was necessary according to national law. RESULTS: Of the sample 39/57 (68.4%) responded. Significant...

    Lichen planus is a chronic autoimmune, mucocutaneous disease, which can affect the oral mucosa, skin, genital mucosa, scalp and nails, and commonly seen in adults. Childhood lichen planus is a rare entity, which is characterized by skin lesions with the oral involvement being extremely uncommon. There are only a few reports on this subject in the literature. Early and correct diagnosis with adequate management is very important to avoid further complications as it is a pre-malignant condition. Herewith, we report a seven-year-old girl having erosive oral lichen planus with cutaneous involvement, which responded well to the treatment. This is to add another case of lichen planus in a child and to emphasize its consideration in the differential diagnosis of oral mucosal red and white lesions in children.

    Lichenoid reactions represent a family of lesions with different etiologic factors and a common clinical and histologic ap-pearance. Lichen planus is included with lichenoid reactions and is a relatively common chronic mucocutaneous disorder. The most important complication of lichenoid reactions is the possibility of malignant transformation. That is why it has been considered a precancerous condition. Although the malignant transformation rate varies widely in the literature, from 0.4 to 6.5 percent, in most studies it does not exceed 1%. The aim of this paper is to report a rare case of squamous cell car-cinoma (SCC) arising within an oral lichenoid lesion in a 17-year-old woman, where SCC is very uncommon. The patient did not have any risk factors and was healthy. The lesion was located on the border of the tongue. In view of thecommon occurrence of OLP (oral lichen planus) and the unresolved issues regarding its premalignant potential, this case report illus-trates the need for histologic confirmation and a close follow-up of clinical lesions with lichenoid features.

    Full Text Available OBJETIVO: Avaliar as características dos portadores de cavidades anoftálmicas que desenvolveram extrusão do implante. MÉTODOS: Estudo retrospectivo, observacional, tendo sido avaliados 37 portadores de cavidade anoftálmica que tiveram extrusão do implante de cavidade, na Faculdade de Medicina de Botucatu-UNESP. RESULTADOS: As extrusões ocorreram em cavidades enucleadas ou evisceradas, a maioria delas submetidas a cirurgia em decorrência de phthisis bulbi ou trauma, em geral de 1 a 2 anos após a cirurgia inicial. A deiscência precedeu a extrusão em todos os casos, tendo a extrusão ocorrido com todos os tipos de implantes empregados. CONCLUSÃO: Após a colocação de implantes de cavidade podem ocorrer complicações. A deiscência e extrusão das esferas são possibilidades que podem requerer nova intervenção cirúrgica, para a qual o paciente e o oftalmologista devem estar preparados.PURPOSE: To evaluate the characteristics of patients with anophthalmic cavity who developed sphere extrusion. METHODS: A retrospective observational study was done evaluating 37 patients with anophthalmic cavity and sphere extrusion at the "Faculdade de Medicina de Botucatu-UNESP". RESULTS: Extrusion was observed in enucleated and eviscerated cavities. The majority of the patients had the eye removed because of phthisis bulbi or trauma and the extrusion happened 1 or 2 years after the surgery. Extrusion was preceded by conjunctival dehiscence and exposure of the sphere and occurred with all used implants. CONCLUSION: Complications after orbital implant placement are a possibility. Dehiscence and sphere extrusion may happen and another surgery would be necessary. The patient and the ophthalmologist have to be prepared for this.

    2014-05-01

    Full Text Available Phaeochromocytoma is a rare neuroendocrine catecholamine-secreting tumour. This type of tumour poses multidimensional anaesthetic challenges as it has an unpredictable clinical course during surgical resection. The alpha-blocking agent phenoxybenzamine remained the mainstay in preoperative preparation before the introduction of beta-blocking agents. We report four cases operated between 2009–2012 at Sultan Qaboos University Hospital, Muscat, Oman. The cases were prepared with oral labetalol, as the alpha-blocking drug phenoxybenzamine was not immediately available. Responses to simulated stress were tested in the theatre before surgery. Anaesthesia was induced under invasive arterial pressure monitoring and magnesium sulphate infusion. Rare intraoperative surges in blood pressure during tumour manipulation were treated with sodium nitroprusside infusions and phentolamine boluses. All of the patients had an uneventful postoperative recovery. Preoperative treatment with labetalol has rarely been reported and can be considered as a potential therapeutic option with optimal patient monitoring if phenoxybenzamine is unavailable.

    Oral submucous fibrosis (OSMF) is a premalignant condition that has received considerable attention in the recent past because of its chronic debilitating and resistant nature. Over the past decades, dental researchers have reported overwhelming evidence about various etiological factors of OSMF. It has been the subject of controversy ever since Schwartz first described the condition in 1952. Areca nut is considered the primary etiology along with other local irritants like capsaicin, pungent and spicy food, nutritional deficiency, defective iron metabolism, collagen metabolic disorder and genetic predisposition. Association of iron deficiency anemia and OSMF is very sparse in literature. Here, we present a case report of a 58 year old male patient where the patient presented with OSMF where iron deficiency anemia was found to be the main etiological factor.

    Full Text Available Abstract Background Information on the impact of oral health on quality of life of children younger than 8 years is mostly based on parental reports, as methodological and conceptual challenges have hindered the development of relevant validated self-reported measures. This study aimed to develop and assess the reliability and validity of a new self-reported oral health related quality of life measure, the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5, in the UK. Methods A cross-sectional study of two phases. First, consultation focus groups (CFGs with parents of 5-year-olds and review by experts informed the development of the SOHO-5 questionnaire. The second phase assessed its reliability and validity on a sample of grade 1 (5-year-old primary schoolchildren in the Greater Glasgow and Clyde area, Scotland. Data were linked to available clinical oral health information and analysis involved associations of SOHO-5 with subjective and clinical outcomes. Results CFGs identified eating, drinking, appearance, sleeping, smiling, and socialising as the key oral impacts at this age. 332 children participated in the main study and for 296 (55% girls, mean d3mft: 1.3 clinical data were available. Overall, 49.0% reported at least one oral impact on their daily life. The most prevalent impacts were difficulty eating (28.7%, difficulty sleeping (18.5%, avoiding smiling due to toothache (14.9% and avoiding smiling due to appearance (12.5%. The questionnaire was quick to administer, with very good comprehension levels. Cronbach’s alpha was 0.74 and item-total correlation coefficients ranged between 0.30 and 0.60, demonstrating the internal consistency of the new measure. For validity, SOHO-5 scores were significantly associated with different subjective oral health outcomes (current toothache, toothache lifetime experience, satisfaction with teeth, presence of oral cavities and an aggregate measure of clinical and subjective oral health

    Full Text Available Langerhans cell histiocytosis (LCH is a rare disease with formation of granulomatous infiltrations consisting of Langerhans cells, histiocytes, lymphocytes and eosinophilic granulocytes. The ethiopathogenesis of the disease has not been fully clarified yet. It can occur as focal or disseminated form - acute or chronic. Oral manifestations may be the first signs. This article reports a case of a 3 year old boy with LCH suffering from severe dental mobility and foul breathe. Radiographically, the lesions appeared as well-defined radiolucent defects in maxilla and mandible. The microscopic findings consisted of sheet like arrangements of histiocytes with a mixture of eosinophils and other inflammatory cells. Biochemical tests were within normal limits.

  20. Oral infections and orofacial pain in Alzheimer's disease: case report and review

    Silvia Regina Dowgan T. de Siqueira

    Full Text Available Abstract Dental infections, frequent in the general population, are a common cause of inflammation with systemic impact, and are the most common cause of orofacial pain. Temporomandibular disorders are also frequent in the elderly and represent an important cause of secondary headache. Both inflammation and pain can also contribute to cognitive, functional and behavioral impairment of the elderly and aggravate symptoms of patients with Alzheimer's disease (AD. We report a case of a 74-year-old woman with AD and chronic facial pain who had a significant improvement in functional activities as well as in cognition and depressive symptoms after successful treatment of her facial pain. Patients with AD have higher compromise of oral health with infections and teeth loss. The investigation of orofacial pain should be performed in patients with AD, because of the associations reviewed and given the potential for improvement as highlighted by this case.

    Full Text Available Lichen planus(LPis a common chronic muco­cuta­neous disease of unknown etiology. Usually, it presents with lesions on the flexor surfaces of the upper extremities, genitalia and mucous membranes. Oral lesions can be the initial as well as the only manifestations of this condition. Patients with LP can present first to the general dental practitioner so sufficient knowledge on this condition is important for the proper diagnosis, treatment and prevention of further complications. The clinical management of LRP requires liaison between dental and medical specialists.This article provides a review of the current literature on LP and a case report of a 55 years old female suffering with this condition. A multidisciplinary approach in the diagnosis and management of this case is described.

    2009-01-01

    Full Text Available Traumatic neuromas are characterized by the presence of pain, burning, or paresthesia, associated with a history of trauma, normally surgery, in the same site. In the oral cavity, the most commonly affected sites are the lip, tongue, and mental nerve area. Pressure on the suspected area usually provokes pain. They microscopically consist of a proliferation of nerve fascicles embedded in a background of collagen. We present a case of a 42-year-old Latin American female patient complaining of a painful solitary nodule erupting on the lingual surface of the mandibular body. Histopathological analysis showed a traumatic neuroma associated with mature ganglion cells, which is an extremely unusual finding. After complete removal of the lesion the symptoms disappeared. To the best of our knowledge, this is the first case of a unique lesion with unusual clinical and histopathological features reported in the English language literature.

    MedEdPORTAL is a unique web-based peer-reviewed publication venue for clinical health educators sponsored by the Association of American Medical Colleges (AAMC). The open exchange of educational resources promotes professional collaboration across health professions. In 2008, the American Dental Education Association (ADEA) collaborated with AAMC to allow dental educators to use the platform to publish dental curriculum resources. Oral health is integral to general health; hence, collaboration among health care professionals brings enormous value to patient-centered care. The aim of this study was to conduct a current survey of metrics and submission statistics of MedEdPORTAL resources. The data were collected using the MedEdPORTAL search engine and ADEA and AAMC staff. The data collected were categorized and reported in tables and charts. Results showed that at the time of this study there were over 2,000 medical and dental resources available to anyone worldwide. Oral health resources constituted approximately 30 percent of the total resources, which included cross-indexing with information relevant to both medical and dental audiences. There were several types of dental resources available; the most common were the ones focusing on critical thinking. The usage of MedEdPORTAL has been growing, with participation from over 190 countries and 10,000 educational institutions around the world. The findings of this report suggest that MedEdPORTAL is succeeding in its aim to foster global collaborative education, professional education, and educational scholarship. As such, MedEdPORTAL is providing a new forum for collaboration and opens venues for promising future work in professional education.

Se presenta el caso de un paciente de 57 años no seropositivo al virus de inmunodeficiencia humana (VIH, con diagnóstico simultáneo de blastomicosis en cavidad oral y papilomatosis laríngea, ambas confirmadas por anatomía patológica. La biopsia de esófago reveló esofagitis granulomatosa con necrosis; la tinción de Ziehl-Neelsen mostró bacilos ácido-alcohol resistente, sugerentes de tuberculosis. El antecedente de tuberculosis pulmonar en dos oportunidades y abandono de tratamiento determinó el inicio de tratamiento antituberculoso de segunda línea a través de un tubo de gastrostomía, más itraconazol vía oral. La evolución fue favorable.Esophageal involvement is an extremely rare complication of tuberculosis even in countries with high prevalence of infection. We report the case of a 57 year-old hiv-seronegative patient with simultaneous diagnoses of oral blastomycosis and laryngeal papillomatosis. Both were confirmed by anatomopathological analysis. The esophageal biopsy revealed granulomatous esophagitis with necrosis and ziehl-neelsen stain showed acid-fast alcohol resistant bacilli suggestive of tuberculosis. The patient’s history included pulmonary tuberculosis twice and previous abandonment of therapy. Thus, it was necessary to use oral itraconazole combined with second-line anti-tuberculosis drugs administered through a gastrostomy tube. The clinical development was favorable.

    Syphilis is a sexually transmitted infectious disease caused by Treponema pallidum. This study reports 3 cases of syphilis and highlights the importance of identifying oral lesions for its final diagnosis. Case 1: a 48-year-old male patient presented with a bleeding ulcer in the lower lip. Overall clinical examination revealed patchy alopecia and skin target lesions. Case 2: a 61-year-old male patient presented with white spots on the lateral tongue and nodules on the dorsum of the tongue. Overall clinical examination showed erythematous target lesions on the abdomen, forearm, palms of the hand, and soles of the feet. Case 3: a 17-year-old male patient presented with an ulcerated lesion on the tongue and lymph node involvement. The following serologic tests were requested: Venereal Disease Research Laboratory, fluorescent treponemal antibody-absorption, anti-HIV-1 and anti-HIV-2, and anti-hepatitis C virus. An incisional biopsy revealed epithelial hyperplasia associated with intense and diffuse mononuclear inflammatory cell infiltration consisting mainly of plasma cells, in a perivascular and perineural distribution. The final diagnosis in the 3 patients was syphilis. Treatment consisted of 1 weekly dose of penicillin (2.4 million units, intramuscular) for 2 or 3 weeks. Immunohistochemical reactions for XIIIa, CD3, CD20, CD68, CD163, S100, CD1a, CD11c, CD83, CD138, and CD208 were performed. Clinicians should be familiarized with oral syphilis lesions in order to be able to diagnose this emerging infectious disease of variable clinical presentation.

    disciplina fácil o que brinde resultados gratificantes con poco esfuerzo debido a las dificultades técnicas que ofrece la reconstrucción correcta de un elemento dentario destruido. Con frecuencia ocurren heridas pulpares durante el anclaje de los elementos adicionales de retención en cavidades complejas, agravadas por las dificultades técnicas que ocasiona la carencia de estos elementos, lo cual justifica la necesidad de simplificar los procederes dentales. Objetivo: Demostrar la factibilidad de la sustitución de los medios adicionales de anclaje por un surco retentivo en cavidades complejas de molares vitales en los que se necesite restaurar más de una cúspide. Métodos: Estudio observacional descriptivo a 53 pacientes (42 % del universo seleccionados mediante un muestreo aleatorio simple. Partiendo de una cavidad próximo-oclusal o MOD, las preparaciones cavitarias se extendieron en forma de cajas hacia región bucal o lingual y se sustituyeron los elementos adicionales de retención por un surco practicado en la pared gingival de la preparación. Se colocó hidróxido de calcio de fraguado rápido como forro cavitario, cemento de policarboxilato como base , y se realizó entonces la restauración de amalgama. Se precisó el número de restauraciones realizadas según la edad y el número de fracasos por fractura de la amalgama, pérdidas de la vitalidad y cambios periapicales teniendo en cuenta la edad y la evolución en un año. Resultados : La mayoría de las restauraciones de amalgama se realizaron en pacientes con edades comprendidas entre 35 y 59 años. Los valores de frecuencia relativa con que ocurrieron las fracturas de amalgama, pérdida de vitalidad y cambios periapicales fueron muy bajos.

    Full Text Available Here, we report a case of severe tooth wear associated with a patient's inappropriate efforts to reduce oral malodor. A 72-year-old male patient visited our breath clinic complaining of strong breath odor. Former dentists had performed periodontal treatments including scaling and root planing, but his oral malodor did not decrease. His own subsequent breath odor-reducing efforts included daily use of lemons and vinegar to reduce or mask the odor, eating and chewing hard foods to clean his teeth, and extensive tooth brushing with a hard-bristled toothbrush. Oral malodor was detected in our breath clinic by several tests, including an organoleptic test, portable sulphide monitor, and gas chromatography. Although patient's oral hygiene and periodontal condition were not poor on presentation, his teeth showed heavy wear and hypersensitiving with an unfitted restoration on tooth 16. Radiographic examination of the tooth did not reveal endodontic lesion, but when the metal crown was removed, severe pus discharge and strong malodor were observed. When this was treated, his breath odor was improved. After dental treatment and oral hygiene instruction, no further tooth wear was observed; he was not concerned about breath odor thereafter.

Oral malodor was detected in our breath clinic by several tests, including an organoleptic test, portable sulphide monitor, and gas chromatography. Although patient's oral hygiene and periodontal condition were not poor on presentation, his teeth showed heavy wear and hypersensitiving with an unfitted restoration on tooth 16. Radiographic examination of the tooth did not reveal endodontic lesion, but when the metal crown was removed, severe pus discharge and strong malodor were observed. When this was treated, his breath odor was improved. After dental treatment and oral hygiene instruction, no further tooth wear was observed; he was not concerned about breath odor thereafter.

    Food allergen oral immunotherapy (OIT) is an experimental, immune-modifying therapy that may induce clinical desensitization in some patients. OIT is still in early phase clinical research, but some providers may offer OIT as a clinical service. To understand the current practices of allergists who perform OIT, an online survey was sent by e-mail to members of the American Academy of Allergy Asthma & Immunology. Among 442 respondents, 61 reported participating in using OIT (13.8%), including 28 in nonacademic settings. Informed consent for OIT was obtained by 91.3%, institutional review board approval by 47.7% and Investigational New Drug approval by 38.1%. Compared with nonacademic participants, more academic participants used peanut OIT, obtained institutional review board and Investigational New Drug (P Food and Drug Administration approval or a standardized product (increased odds), and a high regard for better safety data (decreased odds) were associated with considering offering OIT as a service. Significant differences exist with OITs that occur in academic versus nonacademic settings. Further assessment is needed regarding the different motivations and practice styles among providers who offer OIT and those who are considering doing so.

    Full Text Available Abstract Introduction Circumscript, progressing lipoatrophy at the insulin injection sites is an unexplained, however rare condition in diabetes mellitus. Case presentation We report a case of severe localised lipoatrophy developing during insulin pump-treatment (continuous subcutaneous insulin infusion with the insulin analogue lispro (Humalog® in a woman with type-1 diabetes mellitus. After 11 months of progressing lipoatrophy at two spots on the abdomen, low-dose prednisone (5-10 mg p.o. was given at breakfast for 8 months, whereby the atrophic lesions centripetally re-filled with subcutaneous fat tissue (confirmed by MRI despite ongoing use of insulin lispro. However, 4 weeks after cessation of prednisone, lipoatrophy relapsed, but resolved after another 2 months of low-dose prednisone. No further relapse was noted during 12 months of follow-up on insulin-pump therapy with Humalog®. Conclusion Consistent with an assumed inflammatory nature of the condition, low-dose oral prednisone appeared to have cured the lipoatrophic reaction in our patient. Our observation suggests a temporary intolerance of the subcutaneous fat tissue to insulin lispro (Humalog®, triggered by an unknown endogenous mechanism.

    Carbamazepine (CBZ) is an oral anticonvulsant drug, structurally similar to tricyclic antidepressants. It is preferred over other drugs because it has fewer adverse effects on behavior and alertness. However, hematologic toxicity is possible during therapy with CBZ. Patients should undergo routine monitoring of hematologic function. CBZ can make the skin more sensitive to the sun or ultraviolet light, therefore, dermatological effects of this drug also can happen such as, skin rash, urticaria, and erythema multiforme. The present study reports the case of a female patient that presented hyperchromic-concentric-pruriginous- spots on the skin of her hands after six months of treatment with CBZ. She came to the physicians of the Clinical Pharmacokinetic Service (Laboratory of Toxicology of IAHULA, Mérida-Venezuela) requesting a drug monitoring. The results showed a level of 8.51 microg x. mL(-1), which was found within the therapeutic range (4-12 microg x mL(-1)). Subsequently, the dermatologist diagnosed fixed pigmented erythema related to the ingestion of a specific medication which began disappearing after 15 days of CBZ free-treatment and with the aid of a dermatologic formulation.

    Full Text Available To assess discrepancies in the analyzed outcomes between protocols and published reviews within Cochrane oral health systematic reviews (COHG on the Cochrane Database of Systematic Reviews (CDSR.All COHG systematic reviews on the CDSR and the corresponding protocols were retrieved in November 2014 and information on the reported outcomes was recorded. Data was collected at the systematic review level by two reviewers independently.One hundred and fifty two reviews were included. In relation to primary outcomes, 11.2% were downgraded to secondary outcomes, 9.9% were omitted altogether in the final publication and new primary outcomes were identified in 18.4% of publications. For secondary outcomes, 2% were upgraded to primary, 12.5% were omitted and 30.9% were newly introduced in the publication. Overall, 45.4% of reviews had at least one discrepancy when compared to the protocol; these were reported in 14.5% reviews. The number of review updates appears to be associated with discrepancies between final review and protocol (OR: 3.18, 95% CI: 1.77, 5.74, p<0.001. The risk of reporting significant results was lower for both downgraded outcomes [RR: 0.52, 95% CI: 0.17, 1.58, p = 0.24] and upgraded or newly introduced outcomes [RR: 0.77, 95% CI: 0.36, 1.64, p = 0.50] compared to outcomes with no discrepancies. The risk of reporting significant results was higher for upgraded or newly introduced outcomes compared to downgraded outcomes (RR = 1.19, 95% CI: 0.65, 2.16, p = 0.57. None of the comparisons reached statistical significance.While no evidence of selective outcome reporting was found in this study, based on the present analysis of SRs published within COHG systematic reviews, discrepancies between outcomes in pre-published protocols and final reviews continue to be common. Solutions such as the use of standardized outcomes to reduce the prevalence of this issue may need to be explored.

    This March 2009 Workshop Summary Report was sponsored by Product Quality Research Institute (PQRI) based on a proposal by the Inhalation and Nasal Technology Focus Group (INTFG) of the American Association of Pharmaceutical Scientists (AAPS). Participants from the pharmaceutical industry, academia and regulatory bodies from the United States, Europe, India, and Brazil attended the workshop with the objective of presenting, reviewing, and discussing recommendations for demonstrating bioequivalence (BE) that may be considered in the development of orally inhaled drug products and regulatory guidances for new drug applications (NDAs), abbreviated NDAs (ANDAs), and postapproval changes. The workshop addressed areas related to in vitro approaches to demonstrating BE, biomarker strategies, imaging techniques, in vivo approaches to establishing local delivery equivalence and device design similarity. The workshop presented material that provided a baseline for the current understanding of orally inhaled drug products (OIPs) and identified gaps in knowledge and consensus that, if answered, might allow the design of a robust, streamlined method for the BE assessment of locally acting inhalation drugs. These included the following: (1) cascade impactor (CI) studies are not a good 2 predictor of the pulmonary dose; more detailed studies on in vitro/in vivo correlations (e.g., suitability of CI studies for assessing differences in the regional deposition) are needed; (2) there is a lack of consensus on the appropriate statistical methods for assessing in vitro results; (3) fully validated and standardized imaging methods, while capable of providing information on pulmonary dose and regional deposition, might not be applicable to the BE of inhaled products mainly due to the problems of having access to radiolabeled innovator product; (4) if alternatives to current methods for establishing local delivery BE of OIPs cannot be established, biomarkers (pharmacodynamic or clinical

    Chronic renal failure can give rise to a wide spectrum of oral manifestations, owing mainly to secondary hyperparathyroidism complicating this disease. However, any systemic disease responsible for kidney failure can produce oral manifestations, which can be misdiagnosed. This report describes the case of a 40-year-old male patient referred for oral assessment before kidney and liver transplantation. He had primary hyperoxaluria complicated by end-stage renal failure and secondary hyperparathyroidism. Panoramic radiography indicated not only external root resorption, but also maxillary and mandibular radiolucencies consistent with brown tumors. Unexpectedly, histologic study of the bone biopsy specimen led to the diagnosis of jaws oxalosis. Primary hyperoxaluria is a systemic genetic disease. The affected genes are involved in glyoxylate metabolism and their deficiency results in overproduction of oxalates. Inability of the kidney to excrete oxalates leads to deposition of these crystals in almost all tissues (oxalosis) and to multiple-organ failure. Several oral findings have been described in patients with oxalosis, such as periodontal disease and root resorptions, but radiolucencies in the jaws have rarely been described. This case report is of particular interest because of the unusual location of oxalate crystal deposition in the jaws, which could be misdiagnosed in a patient with renal failure and secondary hyperparathyroidism.

    Full Text Available Certain dipteran flies larvae causing invasion of the tissues and organs of the humans or other vertebrates are called as myiasis, which feed on hosts dead or living tissues. It is well documented in the skin and hot climate regions; underdeveloped countries are affected more commonly. Oral cavity is affected rarely and it can be secondary to serious medical conditions. Poor oral hygiene, alcoholism, senility, or suppurating lesions can be associated with the oral myiasis. Inflammatory and allergic reactions are the commonest clinical manifestations of the disease. In the present case, gingiva of maxillary anterior region was affected by larval infection in a 13-year-old mentally retarded patient.

    The aim of the present study was to evaluate the definition of oral leukoplakia, proposed by the WHO in 2005 and taking into account a previously reported classification and staging system, including the use of a Certainty factor of four levels with which the diagnosis of leukoplakia can be established. In the period 1997-2012 a hospital-based population of 275 consecutive patients with a provisional diagnosis of oral leukoplakia has been examined. In only 176 patients of these 275 patients a firm diagnosis of leukoplakia has been established based on strict clinicopathological criteria. The 176 patients have subsequently been staged using a classification and staging system based on size and histopathologic features. For use in epidemiological studies it seems acceptable to accept a diagnosis of leukoplakia based on a single oral examination (Certainty level 1). For studies on management and malignant transformation rate the recommendation is made to include the requirement of histopathologic examination of an incisional or excisional biopsy, representing Certainty level 3 and 4, respectively. This recommendation results in the following definition of oral leukoplakia: "A predominantly white lesion or plaque of questionable behaviour having excluded, clinically and histopathologically, any other definable white disease or disorder". Furthermore, we recommend the use of strict diagnostic criteria for predominantly white lesions for which a causative factor has been identified, e.g. smokers' lesion, frictional lesion and dental restoration associated lesion.

    2003-01-01

    Full Text Available Objective: We describe four patients presenting early oral cancers, detected cytologically on non‐invasive brush biopsies including DNA‐image cytometry as an adjunctive method before histology on scalpel biopsies confirmed the evidence of malignancy. Methods: Brush biopsies were performed and smears thereof investigated cytologically. After Feulgen restaining, DNA‐measurements were performed using a DNA‐Image‐Cytometer. Case reports: Oral squamous cell carcinomas were diagnosed cytologically in macroscopically suspicious lesions and malignancy confirmed by DNA‐cytometry. The initially performed scalpel biopsies did neither supply evidence of oral cancer nor of severe dysplasia. After at least one to 15 months the occurrence of cancer was finally proven histologically on a second scalpel biopsy each (three microinvasive and one in situ carcinoma. Conclusion: Non‐invasive brush biopsies are a suitable instrument for early cytologic detection of cancer of the mouth. DNA‐image‐cytometry, as an adjunctive method, can be used to confirm the cytologic diagnosis or suspicion of cancer in patients with doubtful lesions (dysplasias. DNA‐aneuploidy is a marker for (prospective malignancy in smears of the oral cavity, which may detect malignancy months prior to histology. In future this method could be used as a mass screening tool in dentists practise. Colour figures can be viewed on http://www.esacp.org/acp/2003/25‐4/remmerbach.htm.

    The objective of this study was to ascertain whether a symposium on elder abuse raises the level of knowledge and the self-reported likelihood to report elder abuse among licensed oral health care providers. 130 dentists, hygienists, and assistants voluntarily attended a 4-hour training symposium and completed both pre- and postsurveys testing their level of knowledge. Results by statistical analyses, using repeated measurements, Wilcoxon signed-rank test for nonparametric data, showed increases in awareness of reporting process, knowledge/awareness of elder abuse, knowledge of mandated reporter requirements, and comfort levels with recognizing signs and symptoms of elder abuse and neglect. In conclusion, a symposium can increase the self-reported likelihood of reporting elder abuse.

    We attempted an oral rush desensitization with mixed cow and sheep milk in a 6-year-old boy who had had adverse reactions to cow and goat milks. Skin prick tests and specific immunoglobulin (Ig) E to cow, sheep and goat milks were positive. The double-blind, placebo-controlled food challenge with cow milk was positive too. He underwent a 12-day sublingual-oral desensitization treatment with mixed cow and sheep milk. Specific IgE and IgG4 were measured. Open oral challenges with cow milk, sheep milk and sheep cheeses were also performed after the desensitization. At the end of the desensitizing treatment our patient could tolerate 120 mL of mixed milk. Specific IgE levels did not vary, whereas an increase of specific IgG4 concentrations was observed. Open oral challenges with cow and sheep milks and sheep cheeses were negative. Oral rush desensitization may represent an alternative approach to the treatment of food allergy in children.

    Full Text Available Introduction: Tetralogy of Fallot is a congenital heart disease and the most common cyanotic heart defect in children. It is clinically characterized by a ventricular septal defect, pulmonary stenosis, overriding aorta over ventricular septal defect and right ventricular hypertrophy. There is little or no information about the oral manifestations in patients with this pathology. A report and discussion of a pediatric patient diagnosed with Tetralogy of Fallot, its clinical manifestations, oral findings and dental management are presented. Case Report: A four-year-old male patient diagnosed with Tetralogy of Fallot and epileptic attacks. The patient has deciduous teeth with many severe early childhood caries, stomatitis and cyanotic mucous membranes, root fragments, periapical abscess and noticeable enamel hypoplasia. Conclusions: In agreement with other authors, children with systemic diseases such as Tetralogy of Fallot have a higher rate of caries, poor oral hygiene, high susceptibility to other infections and bacterial endocarditis, cyanotic mucous membranes and enamel hypoplasia. Primary prevention is critical, proper dental hygiene, regular dental check-ups and the use of antibiotic prophylaxis are particularly important, especially in high-risk patients.

    Full Text Available O presente trabalho tem como objetivo interpretar o contexto geográfico associado à ocorrência de cavidades nos quartzitos da região sudeste de Diamantina/MG - Serra do Espinhaço Meridional. O procedimento metodológico foi composto por revisão bibliográfica; levantamento cartográfico; trabalhos de campo; topografia das cavidades; levantamento das linhas estruturais na área externa e no interior das cavidades; petrografia; coleta, laminação e análise química qualitativa de depósitos químicos e interpretação do contexto geográfico de inserção das cavidades. Os resultados obtidos demonstram que a ocorrência de feições cársticas na área de estudo pode estar relacionada a um conjunto de fatores. Assim, a presença de poliminerais, como mica e feldspato; diferentes camadas estratigráficas da Formação Sopa-Brumadinho (quartzitos monomíticos e conglomerados; os lineamentos estruturais e as características geomorfológicas locais são fatores que contribuem para a ocorrência de cavidades na região. A hipótese de formação das cavidades indica a probabilidade de ocorrência de dissolução, produção de materiais inconsolidados, lixiviação, remobilização dos grãos alterados e ampliação dos condutos através de abatimentos.

    Full Text Available Hereditary sensory and autonomic neuropathies (HSAN are rare genetic syndromes of unknown etiology. They are seen in early childhood and are categorized into six different types by their symptoms. HSAN type 4 demonstrates autosomal recessive transmission pattern, with such major characteristics as loss of sense of pain, self-mutilation, anhydrosis and mental retardation. Sympathetic innervations are deficient despite the existence of sweat glands. Sufferers are hypotonic without any tendon reflexes, and neuro-motor development is retarded. In some cases tactile sensation and vibration may be intact. Biting injuries due to lack of pain sensation cause laceration, ulceration and scarring of the tongue, lips and other parts of oral mucosa. Tooth luxation and severe dental attrition have been observed. This case report presents oral and dental findings, surgical treatments and prosthetic rehabilitation of an 11- year-old boy with HSAN type 4.

    Full Text Available Abstract   Squamous cell carcinoma (SCC is the most common malignant tumors of oral cavity. The ratio of men to women is about 2: 1. Generally, it   is admitted that 60% of carcinoma of the mandibular gingival are located in the posterior of premolars. Gingiva is one of the less common sites of oral squamous cell carcinoma (OSCC. Due to the variable clinical and behavioral presentations, it can easily be misdiagnosed as benign neoplasms or other inflammatory reactions. We encountered a 76-year-old woman with an unusual OSCC on the anterior mandibular ridge, imitating inflammatory hyperplastic (IH lesion in May 2013. She complained that her denture was not seated suitably because of a mandibular lesion. After biopsy of the lesion, the surgeon noticed that real bone resorption was not visible in the x-ray image. Then histopathological evaluation detected the OSCC. Patient was referred to the CT-Scan and MRI. Three months later, the lesion recurred, enlarged and extended rapidly and she was emphasized the importance of a secondary surgery in a timely fashion.. She did not accept and then underwent radiotherapy and chemotherapy. In November 2013, the patient passed away because of the progress of OSCC. This case reminded us to keep the possibility of oral SCC in mind while examining every intra-oral lesion.

    The term leishmaniasis comprises a group of diseases caused by different species of a protozoon called Leishmania. Leishmaniasis is found worldwide, and is considered to be endemic in 88 countries. There are three main clinical forms of leishmaniasis: visceral leishmaniasis, cutaneous leishmaniasis and mucocutaneous leishmaniasis. Exclusive involvement of the mucosa is very rare. We present a series of three cases of mucosal leishmaniasis located in the oral cavity. The fact that all three cases were recorded in Spain (an area where L. infantum is endemic), suggests that the latter was the causal agent. The only manifestation of leishmaniasis disease in the described cases was the appearance of an oral lesion. Treatment was provided in the form of meglumine antimoniate in two patients, with a favorable response. One of the patients left the hospital after diagnosis, without receiving treatment, and the subsequent course is not known. A review is made of the literature on the subject.

    Full Text Available Oral submucous fibrosis is a progressive oral disease first described by Pindborg and Sirsat 3 decades ago. It is a premalignant condition. The signs and symptoms depend on the involvement of the different sites in the oral cavity. The patient feels burning sensation for normal diet and trismus which may be so severe. If not properly treated the risk of malignant change in advanced cases of OSMF is relatively high. Wide ranges of treatment such as medical management, surgical therapy and physiotherapy have been attempted in the past, but none of them has proved to be a cure for this chronic fibrotic disease.Histopathologically as the disease progresses, (i change in the morphology of collagen, (ii increased accumulation of amorphous collagen, and (iii decreased collagen degradation results in decrease in number of blood vessels are observed in the affected area compared to the normal area. With an aim of bringing more blood supply to the affected area which is expected to bring ?more nutrients and help in collagen degradation, earlier application of vasodilators and studies with curcumin have been done, but still with - no significant outcome.As an alternative approach to improve the blood circulation, we have tried Autologous bone marrow stem cells which have been earlier applied in several diseases such as ischemic peripheral vascular diseases, ischemic heart diseases etc with proven improvement in angiogenesis. A 38 year old patient with oral submucosal fibrosis, proven by histopathology, and endothelial markers was injected 175 million BMMNCs into the area affected. The paramaters such as blanching, fibrous band have significantly improved, 4 weeks after the injection. We could observe positive changes clinically to prove the improvement. The mouth opening has improved to 35 mm from the previous 30.0 mm. Further histopathology and SEM studies with larger samples are done for establishing stem cell therapy’s safety and efficacy.

    2005-09-01

    Full Text Available Abstract Background The oral cavity is a rare but occasional target for metastases, which may masquerade as various benign and inflammatory lesions, and sometimes also be asymptomatic. Oral metastatic lesions have been described in various cancers, particularly lung, breast and kidney carcinoma. Case presentation We here describe an uncommon case of a hard palate mucosa and gingival metastasis from gastric carcinoma that was originally diagnosed as a periodontal disease. Histopathological examination of a biopsy of the lesion revealed a signet-ring cell carcinoma, and a subsequent biopsy of an ulcerated stomach lesion showed a poorly differentiated gastric carcinoma. The patient underwent gastric resection but died of heart failure on the tenth postoperative day; a post-mortem examination revealed a residual bilateral ovarian infiltration by gastric carcinoma (Krukenberg's tumor. Conclusion An occult carcinoma of the stomach may rarely metastasise to the oral cavity even as a first and exclusive manifestation; it is important to bear this possibility in mind because such conditions may mimic a benign disease.

    2015-05-01

    Full Text Available Monoculturas de árvores, como as de espécies de eucalipto, têm substituído florestas naturais, impactando a fauna pela perda de habitat e recursos. Diversas espécies de aves necessitam de ocos em árvores para nidificar. A falta de recursos como cavidades formadas pela degradação da árvore ou locais apropriados para serem criadas cavidades leva a diminuição na abundância das populações destas espécies. Este trabalho tem o objetivo de comparar a riqueza e a densidade de aves que nidificam em ocos em áreas de plantação de eucalipto abandonadas com áreas de vegetação nativa em duas unidades de conservação em Minas Gerais. Em cada tipo de vegetação de cada reserva foram estabelecidos 25 pontos, nas quais foi utilizado o método de contagem por remoção para o levantamento das espécies de aves. A riqueza de espécies de aves de cada área foi estimada por Jackniffe e a densidade foi estimada através do método de máxima verossimilhança; modelos candidatos que poderiam influenciar a abundância das aves foram avaliados utilizando-se o Critério de Informação Akaike (AIC. Os resultados mostraram que a riqueza de espécies foi maior nas áreas de florestas nativas e que a densidade foi significantemente mais alta nas áreas de florestas nativas, e que o tipo de vegetação e a hora do dia influenciam na abundância e detecção das aves. Esses resultados indicam que as plantações de eucaliptos influenciam negativamente a comunidade de aves que nidificam em ocos, provavelmente por causa da falta de cavidades ou de sub-bosque. Plantações de eucaliptos normalmente não substituem as florestas nativas e seu uso deve ser controlado em áreas de conservação.

    Full Text Available Aim: Detection of cancer at the early stage is of utmost importance to decrease the morbidity and mortality of the disease. Apart from the conventional biopsy, noninvasive methods like analysis of saliva may provide a cost-effective approach for screening a large population. Thus, this study aimed to estimate salivary levels of sialic acid, total protein, and total sugar in the oral cancer patients and in healthy control group to evaluate their role in diagnosis and prognosis of oral cancer. Study Design: Unstimulated whole saliva samples were collected from 30 healthy controls (Group I and 30 squamous cell carcinoma patients (group II. Estimations of salivary levels of sialic acid, total protein, and total sugar were performed. This was correlated histopathologically with the grades of carcinoma. Statistical Analysis and Results: The Student′s ′ t ′ test and multivariate regression analysis were performed. The results showed that salivary levels of total protein, total sugar, protein-bound sialic acid, and free sialic acid were significantly higher in oral cancer patients compared to those of normal healthy controls ( P values in all the results were less than 0.001. The salivary free sialic acid levels were found to be significantly higher in well-differentiated squamous cell carcinoma than in moderately differentiated carcinoma ( P < 0.001. However, protein-bound sialic acid, total proteins, and total sugars did not show any statistical significance between well and moderately differentiated carcinomas. Conclusion: Biochemical analysis of saliva can be used in early detection of cancer and is best correlated with histopathological degree of squamous cell carcinoma.

    Staphylococcal endocarditis is potentially fatal and is now the most common cause of infective endocarditis with a mortality rate of 25-47% [Hecht SR, Berger M. Right-sided endocarditis in intravenous drug users: prognostic features in 102 episodes. Ann Intern Med 1992;117:560-6]. Its treatment requires maintenance of bactericidal level of antibiotics for prolonged periods to attain a culture-negative state. Although intravenous vancomycin is currently the drug of choice for methicillin resistant Staphylococcus aureus (MRSA) endocarditis, we present a case treated successfully with oral linezolid for 4 weeks due to a lack of venous access.

    Full Text Available Background Hypochlorite solution is widely used in dental practice during root canal treatment. Although it is generally regarded as being very safe, potentially severe complications can occur when it comes into contact with soft tissue especially due to its cytotoxic features. Objective The aim of our paper is to present a case of damage of oral mucosa because of leakage of 3% hypochlorite through rubber dam during endodontic treatment. Material and methods We present a 31 years old female with necrosis of buccal mucosa during the endodontic treatment of 46. Results Three days after the procedure the patient was referred to our department for consultation and treatment. Antiseptic lavage was performed and oral antibiotic was administrated. After 5 days intraoral examination showed signs of almost full recovery. Conclusion The need for proper tooth isolation during restorative procedures is obvious. Anything that obscures the operative field negatively impacts operator efficiency and effectiveness. Visibility, patient/operator safety, infection control and the physical properties of dental materials are all compromised when proper isolation is lacking.

    2015-07-01

    Pyridoxine-dependent epilepsy is a rare, autosomal recessive, treatable cause of neonatal seizures. Genetic testing can confirm mutations in the ALDH7A1 gene, which encodes antiquitin. To avoid delays in initiating treatment while awaiting confirmatory genetic testing, it is recommended that all neonates with unexplained seizures should receive trial of intravenous (IV) pyridoxine to assess for responsiveness. However, oral pyridoxine is not commonly continued in the absence of the typical EEG changes. Two cases are presented that highlight the potential inadequacy of this single-step approach. One neonate ultimately diagnosed with pyridoxine-dependent seizures had no EEG changes after administration of IV pyridoxine. In contrast, another neonate who did not have this diagnosis had profound EEG changes after pyridoxine administration. We present 2 cases that highlight the difficulties in using initial EEG response to IV pyridoxine in establishing a diagnosis of pyridoxine-dependent seizures in the neonate. Given the availability of biochemical markers and gene testing, we suggest that oral pyridoxine treatment should be continued until biochemical and/or genetic testing has confirmed the presence or absence of pyridoxine-dependent epilepsy.

    The solitary fibrous tumor (SFT) is a rare soft tissue tumor with a substantially benign clinical behavior. The SFT of the oral cavity is a very uncommon entity. It is also of complicated diagnosis because of its extensive morphologic diversity and because of its similarity to many mesenchymal tumors. A 44-year-old man was referred for management of an asymptomatic lesion in the left buccal mucosa, which had been identified 10 years earlier. Intra-oral examination revealed a well-demarcated, fibroelastic, rounded exophytic mass located in the left buccal mucosa. The mass was covered with a non-ulcerated mucosa of normal color and measured approximately 4.0 cm in diameter. Histopathological examination showed proliferation of spindle-shaped cells arranged in fascicles and in a patternless pattern, highly vascularized, with focal staghorn vessels. Immunohistochemical analysis revealed diffuse positivity for CD34 and focal positivity for Bcl-2. Awareness of the morphological diversity of SFT coupled to a judicious use of appropriate immunohistochemical probes should prove valuable to accurately segregate SFT from other spindle cell neoplasms.

    Guillaine-Barré Syndrome (GBS), also known as post-infectious polyneuropathy or acute idiopathic polyneuritis, is an infrequent disorder of the peripheral nervous system. The cause of GBS is unknown. It has been associated in the past with microbial infections, vaccinations, surgical procedures and debilitation of the patient. The classic signs of GBS occurring in the two patients being reported here are muscle weakness, motor and sensory impairment and ascending paralysis with respiratory involvement. The documented cases involved GBS syndrome following oral and maxillofacial surgery in which allogeneic-banked freeze-dried bone have been utilized along with autogenous grafting. There were no incidents of viral infection, vaccination or the other prodromal incidents involved in these cases. It is believed that the description of these two cases would be of interest in that it may stimulate the reporting of similar anecdotal occurrences by other surgeons. Both patients fully recovered from the GBS and are presently alive and well. PMID:26261679

    We report a case of ancient schwannoma, which is a rare benign neoplasm of the oral floor and ventricular portion of the tongue. Only two cases have previously been reported in the English literature. The present tumor, measuring 5.5 x 3.0 x 3.0 cm, was the largest of the three. To differentiate ancient schwannoma from schwannoma with malignant transformation, it is important to confirm the absence of abrupt transition between areas of apparently typical schwannoma and areas composed of atypical large cells with pleomorphic and hyperchromatic nuclei, as well as the absence of mitoses, necrosis, and invasiveness. In the present case, calcification was not detected, nor was hyalinization extensive, although many of the neoplastic Schwann cells showed degenerative nuclear atypia.

    Full Text Available A deficiência transversal da maxila é uma anomalia dentofacial relacionada à diminuição do diâmetro do arco maxilar. Este tipo de deformidade está muitas vezes associado a deficiência respiratória nasal, sendo um importante fator etiopatogênico. O tratamento desta atresia pode ser realizado através da Expansão Rápida da Maxila ou Expansão Rápida da Maxila Cirurgicamente Assistida, ficando na dependência da idade do paciente. Ambos os procedimentos levarão a mudanças na estrutura craniofacial, especialmente na cavidade nasal. OBJETIVO: Através da descrição de trabalhos levantados na literatura, procurou-se relatar a relação existente entre a expansão maxilar, cavidade nasal e resistência aérea nasal. MÉTODO: Foi realizada uma tradicional revisão assistemática da literatura, utilizando trabalhos do tipo experimentais, incluindo os que utilizaram Expansão Rápida da Maxila e Expansão Rápida da Maxila Cirurgicamente Assistida, e excluindo os que utilizaram Expansão Maxilar por Osteotomia Segmentada para o tratamento da atresia maxilar. RESULTADO: Tanto a Expansão Rápida da Maxila quanto a Expansão Rápida da Maxila Cirurgicamente Assistida levam a mudanças dentofaciais, especialmente sobre a cavidade nasal, causando um aumento da largura nasal, o que pode levar à diminuição da Resistência Aérea Nasal. CONCLUSÃO: Através dos estudos cefalométricos ântero-posteriores, fica evidente o aumento da largura da cavidade nasal após expansão maxilar.Mandibular cross-sectional deficiency is a dentofacial defect in connection with the narrowing of the mandibular arch width. This abnormality is a significant etiopathogenic factor and it is often associated with nasal breathing difficulties. This atresia may be treated through Rapid Maxillary Expansion or Surgically Assisted Rapid Maxillary Expansion, depending on the patient's age. Both procedures will change the craniofacial structure, especially the nasal cavity

    Full Text Available Behçet's disease (BD is a multi-systemic vascular disorder characterized by oral and genital ulcers, cutaneous, ocular, arthritic, vascular, central nervous system and gastrointestinal involvement. It usually affects young adults and the etiopathogenesis is unknown. A 21-year-old girl, Caucasian, with diagnostic BD, presented with rheumatoid arthritis, genital lesions and multiple recurrent ulcers inside the mouth, with an erythematous halo, covered by yellowish exudates exacerbated during menstrual periods, and in situations of stress and anxiety. The application of low power laser in ulcers was considered in order to decrease the inflammatory symptoms and pain, beyond getting the healing process accelerated. The proposed therapy was able to promote pain relief, increase local microcirculation and repair ulcerated lesions, eliminating the need for administration of systemic or topical medications, leading to improved quality of life.

    2012-10-01

    Langerhans cell histiocytosis (LCH), is a rare, proliferative disorder in which the accumulation of pathologic Langerhans cells leads to local tissue infiltration and destruction. We present a case of a 32 years old, completely edentulous female patient who presented with erythema of hard palate, maxillary alveolar mucosa and mucosa over the distobuccal part of mandibular alveolar ridge with foci of ulcerations. Histopathologic features were suggestive of LCH which was confirmed by immunohistochemistry which was CD1a positive, confirmatory for LCH. Bone scan revealed multiple bone involvement. At this stage, disease had already progressed to multisystem involvement with endocrinal abnormalities (primary hypothyroidism and hyperprolactinemia), requiring aggressive treatment. Therefore, this case is a reminder of the possibility of occurrence of this rare disease in the oral cavity which might manifest itself in multiple presentations thus easily leading to the misdiagnosis and therefore, it could be easily overlooked by dentists. Key words:Langerhans cell histiocytosis, immunohistochemistry, bone scan.

    Full Text Available SUMMARY: Neurilemmoma is a benign tumor originating from Schwann cells of the myelin sheath that covers peripheral nerves. Twenty five to 48% of the neurilemmomas are located at the head and neck area. About 20-58% of those are located intraorally, most frequently involving the tongue and the cheek. Neurilemmomas should be included in the differential diagnosis of intraoral tumors with healthy overlying mucosa. Magnetic resonance tomography is helpful in the preoperative diagnosis and can show the attachment of the neurilemmoma to the nerve from which it derived. Definite diagnosis is established with biopsy. Local excision and reconstruction of the defect is the treatment of choice. In this paper, we present two cases of oral neurilemmoma, one deriving from the hypoglossal nerve that was removed through a submandibular approach and one located on the palate that was excised and the defect reconstructed with buccal fat pad. A literature review is performed regarding pathogenesis, diagnosis and treatment of Neurilemmoma.

    Osteonecrosis of the jaw (ONJ) has been recently described after intravenous administration of amino-bisphosphonates and - less frequently - in association with the use of oral bisphosphonates. Bisphosphonate-Related Osteonecrosis of the Jaw (BRONJ) may affect mandible bone (65%), maxilla bone (26%) and rarely (9%) both sites simultaneously. Although causality may never be proven, emerging experimental data have established a strong association between monthly intravenous bisphosphonate administration and ONJ. Current level of evidence does not fully support a cause and effect relationship between the use of oral BPs and ONJ. In this paper, we report a clinical case of BRONJ in a 73 years old woman affected by rheumatoid arthritis (RA) and periodontitis, after three years of treatment with alendronate 70 mg one a week, plus daily calcium and vitamin D. The patient developed a tooth abscess at the lower jaw, accompanied by increased inflammatory markers, that never returned to normal range despite antibiotic therapy, inducing deterioration of joint synovium. The worsening of joint status after the onset of ONJ was reflected by the progressive increase in the number of swollen (SJ) and tender (TJ) joints, by the deterioration of the score DAS 28 (which passed from 5.46 to 7.07), pain (with VAS increasing from 60 to 90), and by a progressively impaired quality of life, as reported using the HAQ score (from 1,25 to 2,5). The patient was switched to antifracture therapy with strontium ranelate and the osteonecrosis was successfully treated with antibiotics, surgical curettage and local ultrasounds.

    Children with CHARGE syndrome commonly experience feeding and swallowing problems. Difficulties may be associated with congenital structural anomalies, motor impairment, and/or oral sensory impairment. For many children with CHARGE syndrome, the introduction of functional oral feeding is delayed and there are often long-term feeding complications. Oral aversion or defensiveness is a frequent serious issue; however, it is uncertain whether this is a primary sensory disorder or secondary to delayed and/or negative oral sensory and feeding experiences. This article examines in detail the early oral sensory and feeding experiences of five children with CHARGE syndrome, through a review of medical records and caregiver questionnaires. Findings indicate variable early oral sensory experiences in this group of children, with all of the children having some difficulty or delay in the development of oral feeding and swallowing. The nature of these difficulties and the potential contributory factors are discussed.

    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.

    A 54-year-old female presented with severe pain on the gingiva and buccal mucosa. Oral findings revealed generalized fiery red gingiva, ulcerative with white striae covered by pseudo-membranes on both buccal mucosae. She had hypertension, dyslipidemia, subclinical hypothyroidism and arthritis. She was treated with atorvastatin, hydrochlorothiazide, valsartan, levothyroxine and non-steroidal anti-inflammatory drug (NSAIDs). Her oral lesions were a slight improvement from a previous treatment with pimecrolimus cream, triamcinolone acetonide 0.1% orabase and injection. After diclofenac was replaced with tenoxicam and oral lesions were treated with various topical steroids, the lesions showed marked improvement. The biopsy from the buccal mucosa revealed oral lichen planus. Patch test showed positivity to mercury, gold sodium thiosulfate and palladium. One year later the left buccal mucosa showed red, round papillomatous-like lesions. The histopathological report showed a non-specific ulcer with chronic inflammation. The lesions flared up after replacing amalgam with crowns. After CO2 laser treatment, the lesions showed some improvement. Direct and indirect immunofluorescence of the lesions proved to be negative. This first case report showed that the palliative treatment of refractory oral lichenoid lesions with potent topical steroids for 7 years had no side-effects. CO2 laser can be an alternative treatment of refractory lesion in this case.

    2008-12-15

    In July 2008 the Business and Enterprise Committee completed an inquiry into energy prices and fuel poverty but since then there have been a number of developments within the energy sector. Amongst these developments were the publication of Ofgem's energy supply probe, the UK Government's launch of a one billion pound package to tackle fuel poverty and the creation of the new Department of Energy and Climate Change. These events have taken place against the back-drop of a global financial and economic crisis. This report looks at the implications of these developments for the future of the UK's energy policy. This is the Committee's last report on energy-related matters, as from January 2009 responsibility for the scrutiny of energy policy will pass to the new Energy and Climate Change Committee. The report recommends that the Government needs to take action to ensure the credibility of its claims that climate change forms as important a part of the UK's energy policy as security of supply. Further action is required if both nuclear power and coal-fired generation are to form part of the electricity mix in the medium to longer term. The Government will need to learn that new nuclearbuild is not subject to delays and cost over-runs. The national policy statement on nuclear power should be brought forward at the earliest possible date. In addition, much greater levels of investment in carbon capture and storage (CCS) are required than the current single competition for a demonstration plant if the Government wishes to see environmentally acceptable new coal-fired capacity.

    Pica is a compulsive eating of non-nutritive substances and can have serious medical implications. The causes are not known, but the symptom is often associated iron-deficiency. Pica is an under-diagnosed problem. Although few dental problems associated with pica have been reported, because of its potential impact on blood measures, dental professionals must be aware of this common, but commonly missed, condition. This is an unusual case of a patient diagnosed with aggressive periodontitis (AgP) who had a dirt eating habit (geophagia) and was diagnosed as having pica.

    Full Text Available Dysplasia epiphysealis hemimelica, also known as Trevor's disease, is an extremely rare skeletal developmental disorder of unknown etiology, characterized by an osteocartilaginous outgrowth of one or more epiphyses or of a tarsal bone during childhood. It is a rare skeletal hemimelica disorder characterized by asymmetric growth of cartilage in one or more epiphyses. Due to the unusual presentation and variability of the picture, there is no standardized treatment and outcome is very different. Also such an unusual, unique case with craniofacial manifestations has not been reported in the literature. We report a case of a 14-year-old male, who complained of irregularly placed teeth in upper and lower front teeth region. On general physical examination we noticed some skeletal abnormalities with the patient and hence we subjected him to radiographic investigations. The images were consistent with epiphyseal dysplasia hemimelica. The prognosis of DEH is variable and depends basically on its location and size. Carriers of this unusual dysplasia should be periodically monitored for the risk of recurrence. [Int J Res Med Sci 2015; 3(4.000: 1018-1024

    Exhaled breath (EB) is a promising matrix for bioanalysis of non-volatiles and has been routinely implemented for drugs of abuse analysis. Nothing is known regarding the pharmacokinetics of therapeutics and their metabolites in EB. Therefore, we used tramadol as a model drug. Twelve volunteers received a single oral dose of tramadol and repeated sampling of EB, plasma, and oral fluid (OF) was done for 48 h using a particle filter device for EB and the Quantisal-device for OF. Samples were analyzed with LC-MS/MS and the pharmacokinetic correlations between matrices were investigated. The initial tramadol half-life in EB was shorter than in plasma but it reappeared in EB after 8-24 h. The ratio of O-desmethyltramadol to tramadol was considerably lower in EB and OF compared to plasma. This pilot study compared for the first time the pharmacokinetics of a therapeutic drug and active metabolite in different biomatrices including EB and demonstrated its potential for bioanalysis.

    Oral mucositis is a common, dose-limiting, and potentially serious complication of cancer therapy. Severe mucositis can lead to modifications of treatment planning and even suspension of therapy, with a negative impact on local tumor control and patient survival, increasing the risk of local and systemic infections. The lesions generally develop in non-keratinized mucosa, which is most vulnerable to this complication. Symptoms can range from a burning sensation to severe pain that impairs nutrient and fluid intake. Low-energy laser has been proposed for treatment of mucositis, with good clinical and functional results, accelerating the healing process and decreasing the pain. The aim of this article, illustrated by two clinical cases at the Pernambuco Cancer Hospital in Recife, Brazil, was to report on the efficacy of low-energy laser in the management of radiation-induced oral mucositis.(author)

    Background The authors present a case demonstrating the success of topical tacrolimus (TAC) therapy with custom trays in the treatment of oral chronic graft versus host disease (cGVHD). The 41 year-old male patient initially responded to topical steroid therapy (clobetasol propionate 0.05% ointment) applied both topically and with flexible carrier trays, but later became refractory to this potent topical agent. Topical TAC therapy with flexible carrier trays and systemic prednisone therapy was initiated. Results The patient responded favorably with the change to topical TAC therapy with custom trays (and oral prednisone). His oral cGVHD lesions resolved within a period of four weeks. The improvement has remained stable at 14 month follow-up. Clinical Implications This is the first case reported with regard to the successful resolution of steroid recalcitrant cGVHD successfully treated with topical TAC with custom trays. PMID:23102802

    Full Text Available Introduction: The gingiva is often the site of localized growths that areconsidered to be reactive rather than neoplastic in nature. Peripheral ossifying fibromais one such reactive lesion. This case report documents a case of a 15-year-old girl witha large peripheral ossifying fibroma in the posterior maxilla showing significantgrowth and interference with occlusion. Methods: Review of literature concerningetiology, pathogenesis and management of the resulting gingival enlargement isdiscussed. Conclusion: Many of these lesions are difficult to be identified clinicallyand can be identified as specific entity only on the basis of typical and consistenthistomorphology. Surgical treatment of the POF in adolescents should be initiatedsoon, given the high recurrence rate, because although gingival enlargement thatoccurs can be treated, the alveolar bone loss is irreversible, compromising toothsupporting apparatus permanently.

    Staphylococcus spp are not usually isolated from the oral cavity, and when this occurs, they are considered to belong to the transitory microbiota. Individuals with periodontal disease represent possible reservoirs of these opportunistic bacteria in the oral cavity. The use of antibiotics for treatment of periodontal disease or other infections may predispose to the increase of the number of Staphylococcus spp. in the oral cavity. These microorganisms easily become resistant to antibiotics, a...

    The purpose of this case report was to evaluate the efficacy of therapy using LEDs (light-emitting diodes), at a wavelength of 880 nm, in the prevention of oral mucositis in a patient with Hodgkin's disease treated with ABVD regimen. Mucositis is a dose limiting complication of cancer treatment, of high incidence, which severity can lead to alterations of treatment planning or even to suspension of cancer therapy, with serious consequences in tumor response and even survival. Lesions develop most commonly on the nonkeratinized mucosa and present symptoms that begin like mild burning and evolve to severe pain. For this reason, low power laser and, recently, LEDs have been considered for preventing and management of oral mucositis, with great results. In this study, a 34-year-old male received intraoral irradiations with an infrared LEDs array (3,6 J/cm{sup 2}, 74 mW), for five consecutive days, starting on the day of chemotherapy. In each chemotherapy cycle, he received ABVD protocol on day 1 and day 15, and received LEDs treatment during five days on each ABVD infusion. To analyze results, the WHO (World Health Organization) scale was used for grading of mucositis and VAS (Visual Analogue Scale) for pain evaluation, on days 1, 3, 7, 10 and 13 post-chemotherapy. The results obtained showed the patient did not develop oral mucositis, during the five chemotherapy cycles and did not present any pain symptom. Therapy with LEDs was a safe and effective method for the prevention of oral mucositis in this case report. However, new studies are needed in order to prove the efficacy of this methodology with more patients, increasing their quality of life. (author)

    Full Text Available Abstract Background An important aim of antenatal care is to improve maternal health- and well being of which oral health is an important part. This study aimed to estimate the prevalence of oral impacts on daily performances (OIDP during pregnancy, using a locally adapted OIDP inventory, and to document how periodontal status, tooth-loss and reported periodontal problems are related to oral impacts. Methods Pregnant women at about 7 months gestational age who were members of a community based multi-center cluster randomized community trial: PROMISE EBF: Safety and Efficacy of Exclusive Breast feeding in the Era of HIV in Sub-Saharan Africa, were recruited in the district of Mbale, Eastern Uganda between January 2006 and June 2008. A total of 877 women (participation rate 877/886, 98%, mean age 25.6, sd 6.4 completed an interview and 713 (participation rate 713/886, 80.6%, mean age 25.5 sd 6.6 were examined clinically with respect to tooth-loss and according to the Community Periodontal Index, CPI. Results Seven of the original 8 OIDP items were translated into the local language. Cronbach's alpha was 0.85 and 0.80 in urban and rural areas, respectively. The prevalence of oral impacts was 25% in the urban and 30% in the rural area. Corresponding estimates for CPI>0 were 63% and 68%. Adjusted ORs for having any oral impact were 1.1 (95% CI 0.7-1.7, 1.9 (95% CI 1.2-3.1, 1.7 (1.1-2.7 and 2.0 (0.9-4.4 if having respectively, CPI>0, at least one tooth lost, tooth loss in molars and tooth loss in molar-and anterior regions.

    Introducción: el desarrollo de carcinoma escamocelular a partir del liquen plano bucal es controversial. Describimos un caso con carcinoma escamocelular intrabucal, que cursa con lesiones de liquen plano bucal y se analizan las dificultades para distinguir los cambios incipientes del carcinoma escamocelular de las lesiones por liquen plano intrabucales que lleven a establecer un diagnóstico certero de ambas entidades. Caso clínico: hombre de 57 años, con antecedente de tabaquismo y hábito alcohólico crónico, que presenta lesión tumoral ulcerada en borde lateral izquierdo de lengua y placas blancas reticulares bilaterales en mucosa yugal, bordes laterales y vientre de lengua. El reporte histopatológico fue de carcinoma escamocelular invasor moderadamente diferenciado y liquen plano respectivamente. Conclusiones: la naturaleza premaligna del liquen plano bucal es controvertida, esto por inconsistencia en los criterios diagnóstico clínicos e histológicos que permitan diferenciar los casos de liquen plano bucal de otras lesiones como las reacciones liquenoides o displasias intraepiteliales con alto potencial de malignización. Posiblemente las reacciones liquenoides bucales tienen un mayor riesgo de transformación maligna al compararse con el clásico liquen plano bucal.

    Juvenile idiopathic arthritis (JIA) is a severe disease of childhood, which comprises a diverse group of distinct clinical entities of unclear aetiology. Some abnormality of the immune system is present in all JIA cases. In its most severe clinical form, JIA may show localised and/or systemic complications, including functional impairment of the affected sites. This may result in variable growth and developmental anomalies. In many JIA cases, where the temporomandibular joint (TMJ) is affected, mandibular growth may be restricted, thus leading to the development of mandibular hypoplasia and/or retrognathism. As a result, it is not uncommon for JIA patients to present with skeletal Class II and open bite malocclusions. Furthermore, in JIA cases with unilateral TMJ involvement, craniofacial asymmetry may occur. In such cases, early orthodontic intervention facilitates both the skeletal and the occlusal rehabilitation. Increased prevalence of dental caries and periodontal disease in JIA cases may be attributed to a combination of aetiological factors, including difficulties in executing good oral hygiene, unfavourable dietary practices and side effects from the long-term administration of medication. In addition, an association between periodontal disease and JIA has been reported based on their similar pattern of clinical disregulation of the inflammatory process. This paper presents a brief description of JIA, with special reference to dental health and orthodontic treatment considerations. In addition, a case is presented where the appropriate orthodontic intervention led to the establishment of a normally functioning, as well as an aesthetically pleasing, occlusion.

    Full Text Available Background Langerhans cell histiocytosis (LCH is a rare disease in which monoclonal migration and proliferation of specific dendritic cells is seen. The disease primarily affects the bones and skin, but there is a possibility that involves other organs or appears as a multi-systemic disease. Case Report In oral examination of a nine-month girl, two deep wounds with a yellow membrane with approximate size of 1 × 1 cm on both sides of mandibular alveolar ridge were seen. The edges of the wounds were swollen and proliferated and redder than the surrounding mucosa. At the touch the edges of the wound were not indurated. The wound were created from the third-month and the size of wounds had become slightly larger within 6 months. According to the chronic wound and being non-responsive to various systemic and local treatments, incisional biopsy was taken from the wounds. Langerhans cell histiocytosis was confirmedhistologically and immune histochemically. Conclusion Mouth ulcers may be the only symptoms of Langerhans cell histiocytosis. Therefore, the role of dentist could be important in diagnosis of this disease.

    2007-01-01

    The clinical presentation of Ludwig's angina consists in a severe expanding cellulitis causing swelling of the floor of the mouth, tongue and submandibular region, thus resulting in a possible obstruction of the airway and in a rapid progress in deep neck soft tissue infection and mediastinitis with potentially fatal consequences. Frequently, submandibular cellulitis develops from an acute infection spreading from the lower molar teeth. Mandibular fractures, traumatic laceration of the floor of the mouth, and peritonsillar abscesses are other concomitant clinical features. A case of Ludwig's angina associated with a large erupted odontoma and with a deeply impacted third molar displaced to the border of the mandible is described. The patient was affected by enlargement of submandibular space, marked face swelling causing an evident face deformity, tenderness and redness of the neck and limited movement of the neck and mouth. In the past, Ludwig's angina was frequently fatal, however aggressive surgical and medical therapy have significantly reduced the mortality rate. The reported case can be considered as important, not only because of the rarity of the odontoma eruption in the oral cavity, but mainly for the extent of the clinical manifestation of a lesion usually described in literature as asymptomatic.

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.

    Objectives To compare patient-reported outcomes (PROs) in methotrexate (MTX)-naive patients (defined as no prior treatment or ≤3 doses) receiving tofacitinib versus MTX. Methods In the 24-month, phase III, randomised, controlled, ORAL Start trial (NCT01039688), patients were randomised 2:2:1 to receive tofacitinib 5 mg two times per day (n=373), tofacitinib 10 mg two times per day (n=397) or MTX (n=186). PROs assessed included Patient Global Assessment of disease (PtGA), pain, Health Assessment Questionnaire-Disability Index (HAQ-DI), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) and health-related quality of life (Short Form-36 [SF-36]). Results PROs improved following tofacitinib and MTX treatment: benefits were sustained over 24 months. Patients receiving tofacitinib reported earlier responses which were significantly different between each tofacitinib dose and MTX at month 3 through month 24. At month 6 (primary end point), significant improvements versus MTX were observed in PtGA, pain, HAQ-DI, SF-36 Physical Component Summary (PCS), 5/8 domain scores and FACIT-F with tofacitinib 5 mg two times per day; all PROs, except SF-36 Mental Component Summary Score and Medical Outcomes Survey-Sleep, with tofacitinib 10 mg two times per day. At month 6, the proportion of patients reporting improvements ≥minimum clinically important difference were significant versus MTX with tofacitinib 5 mg two times per day in PtGA and 3/8 SF-36 domains; and with tofacitinib 10 mg two times per day in PtGA, pain, HAQ-DI, SF-36 PCS, 4/8 domains and FACIT-F. Conclusions Patients with rheumatoid arthritis receiving tofacitinib 5 and 10 mg two times per day monotherapy versus MTX reported statistically significant and clinically meaningful improvements in multiple PROs over 24 months; onset of benefit with tofacitinib treatment occurred earlier.

Le passage de l’oral à l’écrit a été abordé sous deux dimensions : 1 la première dimension est institutionnelle et pose la question de l’incidence du droit processuel sur les événements rapportés devant la Commission d’enquête. Il est apparu que si l’enregistrement des auditions des enfants était obligatoire, les moyens légaux d’y échapper étaient multiples, de sorte que les procès-verbaux sont restés la référence exclusive dans le cours de l’instruction ; 2 la deuxième dimension est linguistique, et concerne les problèmes de la transcription de l’oral en interaction.

    The clinicopathologic features of 3 new cases and 28 cases obtained from the literature of fibromatosis of the oral and paraoral soft tissues and 9 new cases and 51 cases obtained from the literature of desmoplastic fibroma of the jaws are reported and reviewed. The results of the literature review show that all of the soft tissue lesions occurred before the age of 30 years (mean age, 8.3 +/- 7.0 years). There was a slight male predilection (male to female, 1.2:1). Most cases occurred in the paramandibular soft tissues and mandibular mucosa. Surface resorption of the underlying bone was a common feature. The recurrence rate was 22% and all of these were controlled with further therapy. The desmoplastic fibromas occurred in a slightly older age group (mean age, 14.7 +/- 12.1 years) although 88% of the patients were still younger than 30 years. There was no sex predilection. The vast majority occurred in the area of the mandibular body-angle-ramus. Radiographically, half were unilocular and half were multilocular. Some had poorly defined radiographic margins. The recurrence rate was 25%. The treatment of choice is surgical resection with wide margins, especially for cellular lesions and for those that erode bone with invasion of adjacent soft tissues. Microscopically, both peripheral and central lesions consist of variable proportions of collagen and fibroblasts with a uniform histologic appearance. Hyalinization of collagen is variable but is more frequent in the intraosseous lesions. The cells show no features of anaplasia, and although occasional mitoses may be found, they are always normal in appearance.

    Full Text Available Filariasis affecting animals can rarely cause infections in human beings through the accidental bite of potential vectors. The resulting infection in man, known as zoonotic filariasis occur worldwide. Human dirofilariasis, the most common zoonotic filariasis, is caused by the filarial worm belonging to the genus Dirofilaria. Dirofilarial worms, which are recognized as pathogenic in man can cause nodular lesions in the lung, subcutaneous tissue, peritoneal cavity or eyes. Oral dirofilariasis is extremely rare and only a few cases have been documented. We report an interesting case of dirofilariasis due to Dirofilaria repens involving buccal mucosa in a patient who presented with a facial swelling. The clinical features, diagnostic issues and treatment aspects are discussed. This paper stresses the importance of considering dirofilariasis as differential diagnosis for subcutaneous swelling of the face, especially in areas where it is endemic.

    1980-09-01

    Use of oral syringes at children's and ASHP-accredited residency hospitals in the United States was surveyed. Questionnaires were mailed to 131 hospitals; 117 (89.3%) were returned. Of the responding hospitals, 54.5% of children's hospitals and 67.1% of residency hospitals used oral syringes. There was no definite preference for a particular brand or type (glass vs. plastic) of syringe. Patients who often required liquid dosage forms, including pediatric and geriatric patients and patients with nasogastric tubes, were most frequently included in oral syringe distribution systems. Twenty-six of the 73 hospitals utilizing oral syringes used them for most unit dose liquids in all drug distribution systems. The remainder reported use for specific medications or circumstances. Expiration dating policies varied from 24 hours to one year to the manufacturer's expiration dating. The survey indicates widespread use of oral syringes and identifies a need for evaluation of medication stability in these devices.

    Bisphosphonates are medications used orally and intravenously for a variety of conditions including cancer metastatic to bone, hypercalcemia of malignancy, Paget's disease and osteoporosis. Osteonecrosis of the jaw has been related to bisphosphonate use. Osteonecrosis of the jaw most commonly occurs in the setting of intravenous bisphosphonate use and concomitant dental work or trauma. Oral bisphosphonates have much less risk of osteonecrosis of the jaw. We present an interesting case of a patient on an oral bisphosphonate for an extended period of time (nine years), with a torus palatinus, who burned her palate while eating a slice of pizza. Over six months later, she presented with an area of denuded bone and diagnosis consistent with osteonecrosis of the torus palatinus.

    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.

    2015-01-01

    Full Text Available Intravascular papillary endothelial hyperplasia (IPEH is an unusual reactive lesion of vascular origin, which rarely occurs in the oral cavity. Pathogenetically, is it divided into true, mixed and extra-vascular types. We report a case of extra-vascular IPEH of the lower lip in 54-year-old female patient. Patient gives history of trauma 4 months back with lesion developing at the site to trauma. The lesion was 3 cm × 4 cm in size with soft to firm in consistency. Histologically, it is characterized by an exuberant papillary endothelial cell proliferation toward the lumen of an enlarged blood vessel from the area of an organizing thrombus. The lesion was surgically excised under local anesthesia. The patient was followed for 1-year with no evidence of recurrence. This paper discusses the various aspects of IPEH of the oral cavity such as pathogenesis, clinical features, histopathology treatment, and prognosis.

    Full Text Available Os estudos acadêmicos sobre cavidades naturais em formações ferríferas bandadas e canga, no Quadrilátero Ferrífero - Minas Gerais, são escassos diante do potencial espeleológico desta província mineral. Dentro deste contexto, as cavidades naturais da Serra da Piedade foram objeto de estudo, que tem como principal objetivo levantá-las e classificá-las, de acordo com seus aspectos morfológicos e genéticos, assim como analisar sua distribuição ao longo do relevo. Para isso, os seguintes procedimentos metodológicos foram realizados: (i revisão bibliográfica, (ii caracterização da área de estudo; (iii compartimentação do relevo; (iv prospecção e análise em campo dos aspectos morfológicos e genéticos; (v mensuração da projeção horizontal das cavidades, através de medidas realizadas em campo e mapeamento topográfico; e (vi análise e discussões dos resultados. Os resultados obtidos evidenciaram que existem três tipos de cavidades na Serra da Piedade: cavernas em tálus; cavernas com feições cársticas e cavernas onde não foi possível constatar evidências morfocársticas. De maneira geral, as cavidades formadas por acumulação de matacões encontram-se nos patamares altimétricos mais elevados, entretanto, estão situadas numa declividade relativamente suave. Já grande parte das cavernas sem evidências morfocársticas e das cavernas com feições cársticas estão localizadas na borda do platô de canga. Entretanto, a caverna cárstica de maior projeção horizontal está inserida no interior da unidade escarpa norte. Quanto ao desenvolvimento das cavernas topografadas, constatou-se que aquelas com feições cársticas são maiores do que as cavernas sem evidências morfocársticas.  Pode-se concluir que existem processos de carstificação em cavernas e feições superficiais desenvolvidas no itabirito e na canga, embora as mesmas não sejam tão desenvolvidas como as feições presentes em rochas carbon

  8. Promoting oral health: interventions for preventing dental caries, oral and pharyngeal cancers, and sports-related craniofacial injuries. A report on recommendations of the task force on community preventive services.

    Science.gov (United States)

    2001-11-30

    The Task Force on Community Preventive Services (the Task Force) has conducted systematic reviews of the evidence of effectiveness of selected population-based interventions to prevent and control dental caries (tooth decay), oral (mouth) and pharyngeal (throat) cancers, and sports-related craniofacial injuries. The Task Force strongly recommends community water fluoridation and school-based or school-linked pit and fissure sealant delivery programs for prevention and control of dental caries. Using the rules of evidence it has established, the Task Force found insufficient evidence of effectiveness or ineffectiveness of the remaining interventions reviewed. Therefore, the Task Force makes no recommendation for or against use of statewide or communitywide sealant promotion programs, population-based interventions for early detection of precancers and cancers, or population-based interventions to encourage use of helmets, facemasks, and mouthguards to reduce oral-facial trauma in contact sports. The Task Force's finding of insufficient evidence indicates the need for more research on intervention effectiveness. Until the results of such research become available, readers are encouraged to judge the usefulness of these interventions by other criteria. This report presents additional information regarding the recommendations, briefly describes how the reviews were conducted, and provides information designed to help apply the strongly recommended interventions locally.

    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

    Background Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) is a leading cause of death in cancer patients. The aim of this study was to explore the potential risk factor of VTE in oral and maxillofacial oncological surgery. Material and Methods The data of patients who received operation in our institution were gathered in this retrospective study. A diagnosis of VTE was screened and confirmed by computer tomography angiography (CTA) of pulmonary artery or ultrasonography examination of lower extremity. Medical history and all perioperative details were analyzed. Results 14 patients were diagnosed as VTE, including 6 cases of PE, 7 cases of DVT, 1case of DVT and PE. The mean age of these patients was 62.07 years. Reconstruction was performed in 12 patients of these cases, most of which were diagnosed as malignance. Mean length of surgery was 8.74 hours, and lower extremity deep venous cannula (DVC) was performed in all these patients. Conclusions We analyzed several characters of oral and maxillofacial surgery and suggested pay attention to lower extremity DVC which had a high correlation with DVT according to our data. Key words:Venous thromboembolism, pulmonary embolism, deep vein thrombosis, oral and maxillofacial surgery. PMID:27918738

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

    Full Text Available La leucoplasia oral es la lesión cancerizable más abundante en la cavidad bucal, que con mucha frecuencia puede transformarse en un cáncer bucal; por eso es necesario estudiar desde el punto de vista epidemiológico y clínicopatológico esta entidad. Se realizó un estudio observacional transversal en la población objeto de estudio, que asistió a la consulta de Cirugía Maxilofacial desde junio de 2013 hasta marzo de 2014. El estudio incluyó un total de 24 pacientes con diagnóstico de leucoplasia oral, basado en un interrogatorio, examen físico y biopsia. La investigación tuvo el objetivo de caracterizar desde el punto de vista epidemiológico y clínicopatológico la leucoplasia oral en los pacientes perteneciente a la Clínica Estomatológica Docente Provincial “Ismael Clark Mascaró”, para así describir su comportamiento en esa población. Los grupos de edades más afectados fueron de 35 años en adelante y pertenecientes al sexo masculino. La localización más frecuente fue el labio inferior y en su mayoría no presentaron ningún grado de displasia. El tipo de leucoplasia oral más frecuente fue la homogénea. Todos los pacientes con diagnóstico de leucoplasia oral eran fumadores. Se concluye que la leucoplasia es una lesión cancerizable, frecuente en la cavidad bucal, que afecta a pacientes de la cuarta década de vida, principalmente del sexo masculino y fumadores. El labio inferior fue el sitio más afectado, predominó la forma homogénea y sin displasia

    Full Text Available This is a case of thyrotoxicosis, due to the Jöd-Basedow phenomenon following administration of oral and IV iodinated contrast in a patient with history of gastrointestinal stromal tumor (GIST and small bowel obstruction. The patient developed atrial fibrillation and had an extended stay in the intensive care unit. Given the aging population with possible subclinical hyperthyroidism, multinodular goiter, and the rise in contrast administration for routine diagnostic studies, this case serves to raise awareness of the risks of “routine” tests administered to our aging patient population.

    Full Text Available Renal secondary hyperparathyroidism is a complex clinical syndrome frequently described in dogs. However, in most cases, lesions are characterized by fibrous osteodystrophy of facial bones, affecting principally the mandible and the maxilla. There are few reports of renal secondary hyperparathyroidism associated with facial tumorous masses in the dog; similar findings in dogs have not been previously described in Brazil. This report describes the clinical, pathological, and radiological findings of this syndrome in a 14-month-old dog with oral tumorous-like lesions. The pathogenesis associated with this disease is also discussed.Hiperparatireoidismo renal secundário é uma síndrome clínica complexa freqüentemente descrita em cães. Entretanto, na maioria dos casos as lesões são caracterizadas por osteodistrofia fibrosa dos ossos faciais, afetando principalmente a mandíbula e a maxila. Existem poucos relatos do hiperparatireoidismo renal secundário associada a massas tumorais na face de cães; achados semelhantes em cães não foram anteriormente descritos no Brasil. Este relato descreve os achados clínicos, patológicos e radiológicos dessa síndrome em um cão de 14 meses de idade com lesões semelhantes a tumores na cavidade bucal. A patogenia associada a essa doença também é discutida.

    Full Text Available OBJETIVO: Alterações oculares, em especial a perda de volume nas cavidades evisceradas, promovem uma série de modificações ao paciente tanto funcional do órgão quanto psicológica e estética. Para tanto a procura de um material de baixo custo e com biocompatibilidade tem sido uma constante na literatura. Portanto, esse trabalho teve como objetivo testar experimentalmente implante de polietileno granulado de ultra-alto peso molecular, material de baixo custo, em órbitas de coelhos submetidos à evisceração cirúrgica em vários tempos experimentais, onde foram avaliados aspectos macroscópicos e microscópicose de toxicidade sistêmica do material. MÉTODOS: Para esse estudo foram utilizados coelhos Oryctolaguscuniculus submetidos à evisceração do globo ocular direito e posteriormente implantados com esfera de polietileno granulado de ultra-alto peso molecular e analisados por 15, 30, 90 e 180 dias pós-implante, com parâmetros macro, microscópios e bioquímicos. Os animais controles foram submetidos ao mesmo procedimento sem, entretanto a colocação do implante. RESULTADOS: Os resultados desse trabalho mostram que o material utilizado no implante de cavidade não apresenta alteração significativa nos parâmetros de peso e bioquímicos quando comparados ao grupo controle. O material implantado apresentou uma grande interação com o tecido do hospedeiro. CONCLUSÃO: Os resultados indicam que implante de polietileno granulado de alto peso molecular desenvolvido por uma indústria nacional tem alto potencial para se realizar testes em humanos.

    Full Text Available A lavagem da cavidade abdominal com solução salina 0,9% aquecida é uma prática comum em cirurgia geral, mas, geralmente, não há um controle adequado da sua temperatura, sendo por vezes introduzida na cavidade abdominal a temperaturas elevadas, possivelmente causando lesões no nível celular. O objetivo do trabalho é estudar a célula da parede posterior da cavidade abdominal de ratos após o tratamento desta com solução salina 0,9% aquecida a graus diversos. Foram utilizados 28 ratos divididos em três grupos com 9 animais cada e um rato controle. O grupo A foi tratado com solução salina 0,9% a 37ºC, o grupo B a 45ºC e o grupo C a 60ºC. O rato controle não recebeu tratamento com solução salina 09,%. Em todos os grupos a solução salina 0,9% permaneceu na cavidade durante 1 minuto. Exame histopatológico revelou que no rato controle e nos grupos A e B as fibras musculares e as estriações celulares estavam intactas. No grupo C, no entanto, observaram-se princípios de degeneração celular. Como conclusão ressalta-se a importância de um controle efetivo da temperatura da solução salina 0,9% a ser introduzida na cavidade abdominal de ratos para prevenir um trauma térmico no nível celular.

    A 44-year-old female presented to her general dentist with the chief complaint of a painful mouth sore of 2 weeks duration. Clinical examination revealed an irregularly shaped ulcer of the buccal and lingual attached gingiva of the anterior mandible. A biopsy was performed and microscopic evaluation revealed histoplasmosis. Histoplasmosis, caused by Histoplasma capsulate, is the most common fungal infection in the United States. Oral lesions of histoplasmosis are generally associated with the disseminated form of histoplasmosis and may present as a fungating or ulcerative lesion of the oral mucosa. The histologic findings and differential diagnosis for oral histoplasmosis are discussed.

    Here is a rare case of lingual leiomyomatous hamartoma (LLH) with bifid tongue tip and tongue-tie in a patient with non-oral-facial-digital syndrome (OFDS). A 29-year-old male consulted for a painless tumor over the midline of the tongue dorsum measuring 2 × 1.5 cm. The tumor was excised and the tongue-tie was corrected. Diagnosis of LLH was based on histo-pathologic and immuno-histochemical studies. The epidemiologic data and differential diagnosis of LLH, as well as related literature, are discussed. To date, only 14 cases of LLH have been reported in English literature. This may be the first reported case of LLH with bifid tip and ankyloglossia in a non-OFDS patient.

    Oral disease is exceedingly common in small animal patients. In addition, there is a very wide variety of pathologies that are encountered within the oral cavity. These conditions often cause significant pain and/or localized and systemic infection; however, the majority of these conditions have little to no obvious clinical signs. Therefore, diagnosis is not typically made until late in the disease course. Knowledge of these diseases will better equip the practitioner to effectively treat them. This article covers the more common forms of oral pathology in the dog and cat, excluding periodontal disease, which is covered in its own chapter. The various pathologies are presented in graphic form, and the etiology, clinical signs, recommended diagnostic tests, and treatment options are discussed. Pathologies that are covered include: persistent deciduous teeth, fractured teeth, intrinsically stained teeth, feline tooth resorption, caries, oral neoplasia, eosinophilic granuloma complex, lymphoplasmacytic gingivostomatitis, enamel hypoplasia, and "missing" teeth.

    2016-07-01

    Full Text Available Purpose: The treatment of oral mucosal lesions and mucosal hypertrophy in particular, is most often achieved by an excision with or without covering the surface of the wound. The platelet rich fibrin membrane (PRFm is an autogenous product containing platelets and leukocytes and their secreted growth factors and cytokines. The purpose of the presented clinical case is to describe a new, recent technique used for the covering of mucosal wounds left after the removal of pathological lesions. Material and Methods: On a single patient mucosal hypertrophy was removed by an excision with scalpel and the resulting surgical wound was covered with an autogenous PRF membrane. Postoperatively the healing process was followed on the 7th, 14th and 30th day. Results: The healing period went smoothly with minimal postoperative discomfort and no complications. Conclusion: The results of the presented clinical case demonstrate that the PRF membrane can successfully be used to cover postoperative mucosal defects.

    Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, has been shown to be effective not only for its anesthetic properties but also for the analgesic and opiate-sparing effects. However, data on efficacy and safety of oral ketamine for the treatment of neuropathic or cancer pain syndromes is limited with most of the evidence based on small clinical trials and anecdotal experiences. In this review, we will analyze the clinical data on oral ketamine in the palliative care setting. After an extensive search using five major databases, a total of 19 relevant articles were included. No official clinical guidelines for the use of oral ketamine in this patient population were found. Studies on oral ketamine for cancer and neuropathic pain have shown mixed results which could be partially due to significant differences in hepatic metabolism. In addition, we will include a case report of a 38-year-old female with neurofibromatosis type 1 (NF1) with history of chronic, severe pain in her fingertips secondary to multiple glomus tumors which evolved into CRPS resistant to multiple therapies but responsive to oral ketamine. Based on our experience with oral ketamine, this drug should be administered after an intravenous trial to monitor response and side effects in patients with an adequate functional status. However, patients in the palliative care and hospice setting, especially the one at the end of their lives, may also benefit from oral ketamine even if an intravenous trial is not feasible.

    The traditional transmission pathways of Chagas' disease are vectorial, transfusional, transplacental and organ transplantation. However, oral transmission is gaining importance. The first evidence of oral transmission was reported in Brazil in 1965. Nowadays the oral route is the transmission mode in 50% of cases in the Amazon river zone. Oral infection is produced by the ingestion of infected triatomine bugs or their feces, undercooked meat from infested host animals and food contaminated with urine or anal secretion of infected marsupials. Therefore travelers to those zones should be advised about care to be taken with ingested food. In Chile, this new mode of transmission should be considered in public health policies.

Es una infección frecuente de la cavidad oral de los adultos de edad avanzada. Aunque la incidencia real se desconoce, se sabe que existe una prevalencia aumentada en ciertas ocasiones como ocurre en ancianos, en presencia de prótesis mucosoportadas, xerostomía o en patologías asociadas frecuentemente en los mayores. Los tipos clínicos más característicos son la forma seudomembranosa y la eritematosa (palatina y lingual. Pueden tener evolución aguda o crónica según la persistencia de los factores predisponentes. También son frecuentes procesos bucales comúnmente asociados: estomatitis protética, queilitis angular, glositis romboidal y lengua vellosa. La mayor parte de las candidiasis orales tienen un diagnóstico clínico, pero ha de confirmarse demostrando la penetración de la cándida en la mucosa oral, siendo el frotis la técnica de elección. Antes de comenzar el tratamiento, debemos estar seguros que se trata de una candidiasis oral, el tipo clínico y los factores predisponentes relacionados con la infección. Empezaremos siempre eliminando estos factores predisponentes, en el adulto mayor, la polifarmacología, la xerostomía, enfermedades crónicas y el uso de prótesis mucosoportadas son situaciones frecuentes que habrá que controlar. Instauraremos medidas higiénicas bucales y posteriormente si es necesario, utilizaremos fármacos antifúngicos, comenzando siempre con formas tópicas.

    The Schizophrenia International Research Society held its first scientific conference in Venice, Italy, June 21 to 25th, 2008. A wide range of controversial topics were presented in overlapping and plenary oral sessions. These included new genetic studies, controversies about early detection of schizophrenia and the prodrome, treatment issues, clinical characteristics, cognition, neuropathology and neurophysiology, other etiological considerations, substance abuse co-morbidity, and animal models for investigating disease etiology and for use as targets in drug studies. Young investigators in the field were awarded travel grants to participate in the congress and one of their roles was to summarize the oral sessions and subsequent discussions. The reports that follow are the culmination of this work produced by 30 young investigators who attended the congress. It is hoped that these summaries will be useful synopses of what actually occurred at the congress for those who did not attend each session or were unable to be present. The abstracts of all presentations, as submitted by the authors a few months prior, were previously published as supplement 2 to volume 102/1-3, June 2008.

    Large complex odontomas of the jaws are rare. A report of a large complex odontoma of the mandibular angle-ramus region enucleated through intra-oral buccal approach is presented. A review of the literature on different modalities of treatment is also undertaken. A large expansile complex odontoma of the angle-ramus region of the mandible was excised through an intraoral buccal approach under general anaesthesia. Recovery and immediate post-operative period were uneventful. There was no altered sensation in the distribution of the inferior alveolar nerve and lingual nerve; and wound healing was satisfactory. Post-operative radiograph 2 years after the operation showed satisfactory bone regeneration. Intraoral buccal approach to large complex odontomas of the angle-ramus region of the mandible is a relatively safe procedure with minimal complication.

    Lichen planus is an immunologically mediated mucocutaneous disease that is triggered by varied etiological agents. The oral lichenoid reaction is considered a variant of the disease that needs to be clearly diagnosed as a separate entity from oral lichen planus and treated. They follow a strict cause-effector relationship, protocols that suggest the differentiation. Lichen planus has varied clinical forms in the oral mucosa and cutaneously that has different prognosis. This condition also arises in association with various other systemic conditions such as hypertension, diabetes mellitus. There have been cases reported in the esophagus, larynx, scalp, nail, cutaneous areas, especially arms and wrists, trunk.

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

    Full Text Available Resumo As enfermidades que acometem a cavidade nasal de pequenos ruminantes podem causar prejuízos aos rebanhos de ovinos e caprinos na região central do Brasil. Foi realizado estudo retrospectivo dos laudos de necropsia do Laboratório de Patologia Veterinária da Universidade de Brasília (LPV-UnB nos anos de 2003 a 2014 para verificar a ocorrência das doenças que acometeram a cavidade nasal de pequenos ruminantes. Foram analisados 463 protocolos de ovinos e 75 de caprinos totalizando 538 casos. Seis ovinos (6/463 1,29% foram necropsiados com rinite granulomatosa micótica ou oomicótica e 22 animais do estudo (22/538; 4,08% tiveram o diagnóstico de oestrose, sendo 86,36% ovinos e 13,64% caprinos. As rinites piogranulomatosas em ovinos ocorreram em áreas alagadas, com abundante material vegetal em decomposição. Os ovinos com pitiose rinofacial apresentaram como principais alterações aumento de volume na região nasal devido a extensas lesões granulomatosas associadas a necrose tecidual, caracterizadas por inúmeros macrófagos e polimorfonucleares circundando centros necróticos contendo o agente envolto por reação de Splendore-Hoeppli. Os ovinos com conidiobolomicose exibiram extensas áreas de necrose e inflamação piogranulomatosa, associadas à presença de hifas fúngicas na nasofaringe e também na região peribulbar e exoftalmia. A maioria dos animais com oestrose não apresentou alterações clínico-patológicas significativas, apesar de serem encontradas larvas principalmente nos seios e conchas nasais, traqueia e seio paranasal. A importância dessas enfermidades ainda é pouco conhecida na região, sendo de grande relevância que as condições clínico-patológicas e epidemiológicas sejam elucidadas para o diagnóstico, o controle e a prevenção, para evitar a expansão e prejuízos para os rebanhos.

    A pyogenic granuloma is a tumorlike proliferation that occurs slightly more often in females, frequently involving the gingiva in the maxillary region. Clinically, it presents as a sessile or pedunculated exophytic mass with a smooth or lobulated surface, which tends to bleed easily. Its color can range from pink to dark red. The most common treatment is surgical excision. This case report presents a pyogenic granuloma that formed around an implant 7 years after its insertion. Pyogenic granulomas associated with dental implants are extremely rare; this is the fourth reported case and the first case of pyogenic granuloma to be treated with an Er:YAG laser.

Both ZnO NPs had significant changes in hematological and blood biochemical analysis, which could correlate with anemia-related parameters, in the 500 mg/kg groups of both sexes. Histopathological examination showed significant adverse effects (by both test articles in the stomach, pancreas, eye, and prostate gland tissues, but the particle charge did not affect the tendency or the degree of the lesions. We speculate that this inflammatory damage might result from continuous irritation caused by both test articles. Therefore, the target organs for both ZnOAE100(- and ZnOAE100(+ are considered to be the stomach, pancreas, eye, and prostate gland. Also, the no observed adverse effect level for both test articles was identified as 31.25 mg/kg for both sexes, because the adverse effects were observed at all doses greater than 125 mg/kg. Keywords: zinc oxide nanoparticles, surface charge, 90-day oral dose toxicity, no observed adverse effect level

  8. History of oral contraception.

    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.

    Full Text Available Esta revisión muestra los principales biomarcadores de cáncer oral en saliva. El aspecto clínico y el grado de displasia de las lesiones precancerosas de la cavidad bucal sugieren su capacidad de malignidad; sin embargo, éstas generalmente son diagnosticadas en estadios avanzados, disminuyendo la probabilidad de supervivencia, lo que justifica el diseño de nuevas pruebas diagnósticas que determinen el grado de alteración celular, permitan comprender el proceso degenerativo en el cáncer y establezcan diagnósticos precoz. Esta búsqueda para mejorar los métodos diagnósticos, apunta a que sean sensibles, específicos y menos invasivos, por lo cual el estudio de diferentes biomarcadores en saliva que desde una perspectiva molecular proporcionan información adicional al examen clínico e histopatológico, es considerada como una alternativa eficaz y más cómoda con respecto a los ensayos en sangre. Los biomarcadores que se han descrito en saliva algunos mostrando mayor relación con la carcinogénesis oral son: Ciclina D1, cyfra 21-1, endotelina-1, galectinas 1, 3 y 7, Ki67, lactato deshidrogenasa, metaloproteinasas 2 y 9, proteína p53, proteína de unión a calcio (S100P y telomerasa.

    Full Text Available Fractures of severely atrophic (height < 10 mm edentulous mandibles are infrequent and challenging to manage. Factors such as sclerotic bone and decreased vascularity combined with systemic diseases complicate the management of such fractures. Osteogenesis imperfecta (OI is a heterogeneous group of inherited disorders of type I collagen metabolism. Patients with OI characteristically present with histories of long bone fractures, deformities, blue sclerae, and opalescent dentin. However, fractures of the facial skeleton are rare. Bisphosphonate therapy has been proven to effectively reduce the fracture risk in patients with OI. The purpose of this clinical report is to present an unusual case of spontaneous fracture of the atrophic mandible in a patient with OI. Despite open reduction and internal fixation (ORIF with miniplate osteosynthesis, the patient developed a second fracture at a screw placement site distal to the first fracture. The patient was successfully treated with ORIF using locking reconstruction plates fixed in the symphyseal and angle regions. Bone healing following ORIF was normal, and no clinical sign of osteonecrosis as a result of bisphosphonate therapy was observed. Patients with OI can present with spontaneous fractures of already weakened mandibles. Although such fractures can be managed with care using established protocols, further research is required to examine the effects of concomitant medication, such as bisphosphonates.

    Treatment options for patients with lower risk non-del(5q) myelodysplastic syndromes (MDS) who fail erythroid stimulating agents are restricted to one of the hypomethylating drugs with an expected response rate of approximately 50%. Ezatiostat HCl, an agent with the potential for producing multi-lineage responses in this population is currently in clinical investigation phase. This case report describes a 77 year old male who received less than two cycles of therapy with ezatiostat HCl which had to be aborted due to intolerable side effects, but which produced a sustained normalization of all three blood counts. This trilineage response has now lasted for more than a year. Interestingly, the patient began with a del(5q) abnormality and responded briefly to lenalidomide. Upon relapse of the anemia, a bone marrow showed the disappearance of the del(5q) but the appearance of a new clonal abnormality t(2;3). Given that the patient had a complete cytogenetic response to a truncated exposure to lenalidomide followed by a trilineage response to an even briefer course of ezatiostat HCl suggests a potential role for ezatiostat HCl in del(5q) patients who relapse following lenalidomide.

    Over 60 million women use highly efficient and safe modern combined oral contraceptives (OCs) every day. A women who takes the oral contraceptive for 5 years before the age of 30 will actually live 12 days longer, although a woman taking the pill for the 1st time for 5 years after the age of 30 will have her life span reduced on the average by 80 days. OC related morbidity and mortality mostly occur in women over 35 who smoke. Combined low dose OCs are safe for women who do not smoke, at least to 45 years of age and probably to the menopause. The prescription of OCs is also safe to the young adolescent. The pill does not interfere with maturation of the hypothalamic-pituitary ovarian axis and does not increase the incidence of amenorrhoea, oligomenorrhoea or infertility in later life. Patients with contraindications to estrogen therapy are excluded from OC use (history of thromboembolism, major heart disease, liver disease, breast cancer). Low-dose (30-35 mcg estrogen-containing monophasic or triphasic) pills are recommended. Combined oral contraceptives contain either ethinyl estradiol (1.7 to 2 times more potent) or mestranol. After absorption the progestagens, norethisterone acetate, ethynodiol diacetate and lynoestrenol are all metabolized to norethisterone. The progestagen-only pill has about a 2% failure rate and poorer cycle control than the combined pill, but it lacks estrogenic, progestagenic and androgenic side effects. This pill is suitable for the lactating mother, for smokers over 35, for hypertensive patients, and for those with a history of thrombosis. The efficacy of the progestagen-only pill is restored in 3 days of pill taking. Postcoital contraception is an alternative: treatment can be given for at least 72 hours after intercourse. The Yuzpe method calls for the patient to take 2 combined oral contraceptive tablets containing levonorgestrel and ethinyl estradiol (Eugynon or Ovral) followed by a further 2 tablets 12 hours later.

O valor preditivo positivo foi de 42,8% e o negativo 98,4%. A razão de probabilidades do teste positivo e a razão de probabilidades do teste negativo foram respectivamente 7,6 e 0,16. A acuidade da histeroscopia foi de 88,4% e o índice kappa 0,5. CONCLUSÃO: a histeroscopia isoladamente não apresentou, no presente estudo, acurácia aceitável, reforçando o conceito de que sua principal vantagem é dirigir a biópsia, devendo sempre estar associada ao diagnóstico histopatológico.

    Full Text Available Cyclic Neutropenia (CN is characterized by recurrent infections, fever, oral ulcerations, and severe periodontitis as result of the reduced host defences. The previous studies have established the effectiveness of recombinant granulocyte colony-stimulating factor (GCSF to increase the number and the function of neutrophils in the peripheral blood in this disease. In a 20-year-old Caucasian female with a diagnosis of cyclic neutropenia, oral clinical examination revealed multiple painful ulcerations of the oral mucosa, poor oral hygiene conditions, marginal gingivitis, and moderate periodontitis. The patient received a treatment with G-CSF (Pegfilgrastim, 6 mg/month in order to improve her immunological status. Once a month nonsurgical periodontal treatment was carefully performed when absolute neutrophil count (ANC was ≥500/L. The treatment with G-CSF resulted in a rapid increase of circulating neutrophils that, despite its short duration, leaded to a reduction in infection related events and the resolution of the multiple oral ulcerations. The disappearance of oral pain allowed an efficacy nonsurgical treatment and a normal tooth brushing that determined a reduction of probing depth (PD≤4 mm and an improvement of the oral hygiene conditions recorded at 6-month follow-up.

  18. An examination of the advances in science and technology of prevention of tooth decay in young children since the Surgeon General's Report on Oral Health.

    2009-01-01

    This paper addresses a number of areas related to how effectively science and technology have met Healthy People 2010 goals for tooth decay prevention. In every area mentioned, it appears that science and technology are falling short of these goals. Earlier assessments identified water fluoridation as one of the greatest public health accomplishments of the last century. Yet, failure to complete needed clinical and translational research has shortchanged the caries prevention agenda at a critical juncture. Science has firmly established the transmissible nature of tooth decay. However, there is evidence that tooth decay in young children is increasing, although progress has been made in other age groups. Studies of risk assessment have not been translated into improved practice. Antiseptics, chlorhexidine varnish, and polyvinylpyrrolidone iodine (PVI-I) may have value, but definitive trials are needed. Fluorides remain the most effective agents, but are not widely disseminated to the most needy. Fluoride varnish provides a relatively effective topical preventive for very young children, yet definitive trials have not been conducted. Silver diamine fluoride also has potential but requires study in the United States. Data support effectiveness and safety of xylitol, but adoption is not widespread. Dental sealants remain a mainstay of public policy, yet after decades of research, widespread use has not occurred. We conclude that research has established the public health burden of tooth decay, but insufficient research addresses the problems identified in the report Oral Health in America: A Report of the Surgeon General. Transfer of technology from studies to implementation is needed to prevent tooth decay among children. This should involve translational research and implementation of scientific and technological advances into practice.

    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.

    Four human immunodeficiency virus-positive homosexual men with 2- to 4.5-year histories of recurrent oral warts that had failed to respond to conventional surgical and other treatment modalities were offered treatment with interferon-alpha. All had multiple or large oral warts, 3 had skin warts, 2 had a history of anal warts, and 1 had penile lesions. All 4 patients were treated with a combination of intralesional and subcutaneous interferon-alpha. Adverse side effects were dose-related, mild, and transient; they included flulike symptoms (3 patients), hair loss and tachycardia (1 patient), and transient changes in the white blood cell count. All patients responded to therapy and remained free of disease up to 42 months. Intralesional injection with interferon-alpha appears to provide excellent clinical control for recurrent, multiple, and extensive oral warts in the human immunodeficiency virus-positive population, and is a useful adjunct to initial surgical removal of oral warts.

  2. Oral sex, oral health and orogenital infections

    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.

    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.

    In view of high availability and diversity of non-steroidal anti-inflammatory drugs (NSAIDs) on Polish market it is important for orthodontists to be aware of NSAID effect on the range of orthodontic tooth movement as well as the risk of root resorption in the moved teeth and other adverse effects, which might occur within oral cavity. The disadvantages of NSAID non-selective inhibition of COX include common oral inflammatory conditions, gingival bleeding, and disturbances of salivary secretion. Both, the selective and non-selective COX inhibitors, meloxicam excluded, used to alleviate the pain of orthodontic tooth movement, impede the movement of teeth. Paracetamol, explicitly indicated by most authors as the safest NSAID, seems to be the drug of choice in view of no influence on the range of tooth movement, the risk of root resorption or other adverse effects within oral cavity.

    Angioleiomyoma (AL) is a benign neoplasia originating from smooth muscle and very uncommon in the oral cavity. The most frequent subtype in the oral cavity is the vascular one. AL usually occurs in the extremities: only around 12% are found in other areas such as head and neck. It presents as an asymptomatic, slow growing nodule lodging in the palate, tongue or lips. The diagnosis is essentially by histological exam and special specific stains are helpful to confirm the origin and to distinguish it from other tumors. We present a case of AL found in unusual site: attached to the submandibular region in a deep-seated space.

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

    Full Text Available Aims: To determine the level of oral cancer awareness and knowledge among patients referred to the Department of Oral and Maxillofacial Radiology in Central Anatolia. 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.

    2007-01-01

    Objective: To observe the clinical therapeutic effects of Rehmannia Oral Liquid on the syndrome of heat accumulation with Yin consumption in intermediate or late esophagus cancer patients undergoing radiotherapy. Methods: The IFN-α, TNF-α, IL-1β and TGF-β1 levels in sera were determined by the method of ABC-WLISA before and after the treatment with Rehmannia Oral Liquid. At the same time, the observation was carried out on the patient's general condition, symptoms and signs, barium meal or CT examinations, and biopsy. Another 30 cases of esophagus cancer were treated singly with radiotherapy as the control group. Results: Rehmannia Oral Liquid could obviously improve the patient's general condition, and the symptoms and signs after radiotherapy. Based on the X-ray examination and biopsy, the short-term local control rate of the treatment group and the control group was 70.0% and 40.0% respectively, showing a significant difference (P0.05) after treatment. The difference between groups was significant (P<0.05). Conclusion: Rehmannia Oral Liquid can obviously reduce the radiotherapy reaction, improve the quality of life, and raise the therapeutic effects. The action mechanism of the Liquid may lie in balancing the cytokine network and regulating the disordered signal transmission.

  13. Extra-oral halitosis: an overview.

    Science.gov (United States)

    Tangerman, A; Winkel, E G

    2010-03-01

    Halitosis can be subdivided into intra-oral and extra-oral halitosis, depending on the place where it originates. Most reports now agree that the most frequent sources of halitosis exist within the oral cavity and include bacterial reservoirs such as the dorsum of the tongue, saliva and periodontal pockets, where anaerobic bacteria degrade sulfur-containing amino acids to produce the foul smelling volatile sulfur compounds (VSCs), especially hydrogen sulfide (H(2)S) and methyl mercaptan (CH(3)SH). Tongue coating is considered to be the most important source of VSCs. Oral malodor can now be treated effectively. Special attention in this overview is given to extra-oral halitosis. Extra-oral halitosis can be subdivided into non-blood-borne halitosis, such as halitosis from the upper respiratory tract including the nose and from the lower respiratory tract, and blood-borne halitosis. The majority of patients with extra-oral halitosis have blood-borne halitosis. Blood-borne halitosis is also frequently caused by odorous VSCs, in particular dimethyl sulfide (CH3SCH3). Extra-oral halitosis, covering about 5-10% of all cases of halitosis, might be a manifestation of a serious disease for which treatment is much more complicated than for intra-oral halitosis. It is therefore of utmost importance to differentiate between intra-oral and extra-oral halitosis. Differences between intra-oral and extra-oral halitosis are discussed extensively. The importance of applying odor characterization of various odorants in halitosis research is also highlighted in this article. The use of the odor index, odor threshold values and simulation of bad breath samples is explained.

    Intranasal tumors are uncommon and in most cases are malignant, aggressive and with low to moderate potential for metastasis. Clinical signs are usually caused by progressive obstruction of the upper airways. The test cytopathological also is a diagnosis method, but the definitive diagnosis is made by histopathological. Computed tomography (CT) is recommended to treatment planning. A poodle was attended at the veterinary hospital with a clinical history of epistaxis and nasal and ocular secretions, seizures and severe dyspnoea. The animal underwent to radiographic examination of the chest and skull as well as helical computed tomography of the nasal cavity and brain before and after the administration of intravenous contrast. The CT findings revealed an expansive bilateral nasal cavity neoformation, with involvement of the retrobulbar space, right frontal sinus, brain and oral cavity, suggesting a neoplastic or an infectious process. The CT examination allowed the material collection, directly from the mass, to cytological examination, providing the diagnosis of carcinoma. CT also allowed the determination of the unfavorable prognosis of the patient and the treatment planning which not included the surgical excision of the neoformation. Although CT was not conclusive in the diagnosis of carcinoma, it was essential to accurately define the extent of the lesion, to guide the collection of material directly from the tumor and to determine the prognosis of the animal, proving to be an extremely useful tool in cases of tumors intranasal in dogs.

    Wilson's disease (WD), also known as hepatolenticular degeneration, was first described in 1912 by Kinnear Wilson. It is an autosomal recessive disorder caused by mutations in the ATP7B gene, a membrane-bound copper transporting ATPase. The disorder is caused by impairment of the copper transporting ATPase, ATP7B, in the liver, which disturbs copper transport, excretion into the bile, and incorporation into apoceruloplasmin. WD is an inherited copper metabolism disorder with pathological copper accumulation in many tissues, but especially in brain and liver. We conducted this study because copper accumulation in oral tissues in patients with WD have not been studied before. We think that copper accumulation and differences of oxidative events in oral tissues can cause tendency to periodontal diseases.

    We report the case of an HIV-positive patient with visceral leishmaniasis and several relapses after treatment with the two first-line anti-leishmanial drugs, liposomal amphotericin B and miltefosine. End-stage renal failure occurred in 2007 when the patient was on long-term treatment with miltefosine. A relapse of leishmaniasis in 2008 was successfully treated with a novel combination regimen of intravenous pentamidine and oral fluconazole. Secondary prophylaxis with fluconazole monotherapy did not prevent parasitological relapse of leishmaniasis.

    Full Text Available The antimicrobial activity of Aegiphila sellowiana Cham., Lamiaceae, against oral pathogens is reported. The Minimal Inhibitory Concentrations (MICs for inhibiting the microorganisms growth were determined using the broth microdilution method from the CLSI M7-A7 protocol. Chlorhexidine was used as the positive control. The ethanol crude extract of the aerial parts of A. sellowiana exhibited activity against the microorganisms tested in this work; however, the activity decreased after partition with n-hexane, dichloromethane, and ethyl acetate. Among the tested fractions, the n-hexane fraction was found to be the most effective against the evaluated oral pathogens. GC-MS analysis of this latter fraction revealed that fatty acids esters, steroids, and aliphatic sesquiterpene hydrocarbons are its major constituents. These compounds may be responsible for the activity of the n-hexane fraction, but other chemical constituents of the dichloromethane, ethyl acetate, and hydroalcoholic fraction may potentialize their activities in the crude extract.A atividade antimicrobiana de Aegiphila sellowiana Cham., Lamiaceae, contra patógenos da cavidade bucal foi avaliada empregando-se o método de microdiluição em caldo, segundo o protocolo CLSI M7-A7, utilizando-se clorexidina como controle positivo. O extrato etanólico bruto das partes aéreas de A. sellowiana, obtido por maceração, exibiu atividade contra os microrganismos testados neste trabalho, entretanto, os valores de CIM (concentração inibitória mínima aumentaram após a partição com n-hexano, diclorometano e acetato de etila. Entre as frações testadas, a fração n-hexânica foi a mais efetiva contra os patógenos bucais avaliados, com valores de CIM entre 140 e 350 µg/mL-1. Dados obtidos por CG-EM revelaram que ésteres de ácidos graxos, esteróides e hidrocarbonetos sesquiterpênicos alifáticos são os constituintes majoritários desta fração. Embora esses compostos possam ser os

    Contact/allergic dermatitis is frequently treated inappropriately with lower-than-recommended doses or inadequate duration of treatment with oral and intramuscular glucocorticoids. This article highlights a case of dermatitis in a Ranger Assessment and Selection Program student who was improperly treated over 2 weeks with oral steroids after being bit by Cimex lectularius, commonly known as bed bugs. The article also highlights the pitfalls of improper oral steroid dosing and provides reasoning for longer-duration oral steroid treatment.
