Oral candidosis and the therapeutic use of antifungal agents in dentistry

This paper reviews the current concepts of mycology and candidal infections as they relate to the oral cavity. Proposed classification for the presentation of oral candidosis is outlined as are examples of these topical infections, such as erythematous, pseudomembranous and hyperplastic candidosis, as well as angular chelitis and median rhomboid glossitis. The diagnosis and principles of management of oral candidosis are discussed, the therapeutic agents available for the management of these infections are presented and a treatment protocol for the management of patients with oral candidosis is given.

Oral viral infections and the therapeutic use of antiviral agents in dentistry

This paper reviews the current concepts of viral classification, infection and replication. The clinical presentation of common oral viral infections encountered in the dental practice are discussed, including: herpes simplex virus types 1 and 2; Epstein-Barr virus; varicella-zoster virus; Coxsackie virus; human papilloma virus; and human immunodeficiency virus. The diagnosis, principles of management and pharmacological agents available for the treatment of oral viral infections are also discussed.

Burning mouth syndrome: clinical presentation, diagnosis and treatment

Burning mouth syndrome is an oral dysaesthesia presenting as a burning sensation of the tongue and less frequently other oral and peri-oral sites. There may be other coincident symptoms and signs, but the defining feature is the absence of any obvious organic cause. Because of this the condition frequently remains unrecognized for extended periods with a variable progression of symptoms. The current paper describes the complex presentation of burning mouth syndrome with the major aim of increasing recognition.

Patients' perceptions and experiences of taking oral glucose-lowering agents: a longitudinal qualitative study

Aims The aims of this study were to examine Type 2 diabetic patients' expectations, perceptions and experiences of oral glucose-lowering agents (OGLAs), including their reasons for taking/not taking these drugs as prescribed and to provide recommendations for developing interventions to improve OGLA adherence. Methods Longitudinal, qualitative study using repeat in-depth interviews with patients (n = 20) over 4 years following clinical diagnosis. Respondents were recruited from primary and secondary care settings across Lothian, Scotland, UK. Results Despite experiences of side-effects, dislikes and concerns about taking multiple drugs and a belief that OGLAs could themselves cause one's diabetes to progress, most respondents appeared motivated to take these drugs as prescribed. This motivation seemed to arise from respondents' experiences of taking OGLAs and observing them to 'work'. Some respondents described feeling better after taking OGLAs, others, typically those who were asymptomatic, used blood glucose self-monitoring and/or glycated haemoglobin results to observe and evidence the effects of their OGLAs. Most respondents demonstrated a 'passive' expectation that health professionals should be responsible for decisions about medications. Hence, non-adherence typically resulted from forgetfulness rather than ambivalence about either medication or consultation style. Respondent concern about OGLA's largely centred upon lack of knowledge about the medication and what to do when doses were missed. Conclusion The findings call for multifaceted strategies to promote adherence. These could include education to address misconceptions and advise patients how to respond to missed doses; reminders to help patients remember to take their drugs; and structured feedback on the impact of OGLAs on glycaemic control.

Trajetória de pessoas com AIDS em situação de vulnerabilidade social: à luz da história oral de vida

The epidemic caused by HIV presents a global, dynamic and unstable phenomenon, which depends on the individual and collective human behavior. Efforts to deconstruct the stigmatized image caused by infection of AIDS are still often associated with adoption of socially unacceptable behavior to be a circumscribed the susceptibilities of vulnerable individuals and communities to infection, illness and death by HIV. This study aimed to: narrate the trajectory of life of people with AIDS more vulnerable enrolled in the Municipal Social Assistance Parnamirim / RN. It is a study of qualitative, exploratory and descriptive approach, taking oral history of life as technical and methodological framework. The colony consisted of 186 people with AIDS. The network was comprised of 13 employees of both sexes, aged between 19 and 62 years old with positive diagnosis and agreed to voluntarily participate. After approval by the Ethics Committee of the Federal University of Rio Grande do Norte (CEP / UFRN), in the opinion No. 719,926 CAAE: 30408114.5.0000.5537 on 6 June 2014 data were collected from August to September 2014. The employees signed the Informed Consent and Informed and letter of assignment. Held transcribing the interviews and later returned to respondents to retest, ie so that they confer what allowed us to carry out transcreation after consecutive readings. The reports were analyzed through Bardin content analysis. Guiding the analysis of the accounts of employees, we find three themes: Prejudice and discrimination in living with AIDS; Reacting to the diagnosis and the accession process to antiretroviral treatment; and religious coping in people with AIDS. It can be concluded in this study, that employees have shown great emotional impact after positive diagnosis for HIV / AIDS, especially with regard to social life, the family ties, work and above all to the prejudice of society. Treatment with antiretroviral drugs was seen as a motivation to regain dreams and plans for a future once uncertain, and even if it is not a cure therapy, provided the employees improved quality of life.

Neurilemmoma of the oral cavity in pediatric patient

Neurilemmomas arising from Schwann cells, rarely found in oral cavity, are characterized by solitary occurrence, slow growth and smooth surface with variable clinical aspects, depending on the nerve origin. Most instances are typically asymptomatic. Microscopically, the histopathological characteristic consists of alternating regions of hypercellularity and hypocellularity such as Antoni A and Antoni B, respectively. The prognosis is favorable; complete surgical removal is the treatment of choice, no recurrence should be expected. The present report shows the case of neurilemmoma in bucal mucosa, in a 9-year-old child. Patient was referred to the Stomatology Clinic of School of Dentistry, Universidade Federal do Rio Grande do Norte, with complaint of nodular mass, with approximately one year development. Patient was submitted to excisional biopsy, with histopathological exam showing diagnosis of neurilemmoma. After 1 year follow-up there has been no recurrence of lesion.

Revisão de literatura de Leucoplasia Oral

Similar a outras lesões de pele, têm sido identificadas lesões precursoras de carcinoma de células escamosas na mucosa da cavidade oral. Na boca, apresenta-se frequentemente em forma de placa branca, denominada leucoplasia. Na conferência de 2005, a leucoplasia foi definida pela OMS como “uma placa ou mancha branca que não pode ser caracterizada clínica ou patologicamente como qualquer outra doença.” Leucoplasia é, portanto, um diagnóstico clínico de exclusão. A frequência de apresentar displasia epitelial, carcinoma in situ, carcinoma verrucoso ou carcinoma de células de escomosas invasivo na leucoplasia oral varia de 8,6% a 60%. A transformação maligna anual de leucoplasia é de 1% a 5 %. Sendo assim, é de fundamental importância, por parte dos profissionais na saúde e principalmente dos médicos dentistas terem conhecimento da leucoplasia oral para que possam suspeitar, fazer o diagnóstico ou encaminhar a profissionais competentes precocemente para o manejamento dessas lesões.

Potencial de malignização do líquen plano oral

Ao Médico Dentista cabe o diagnóstico e o tratamento de todas as perturbações que afetem a cavidade oral e estruturas anexas e, embora a cavidade oral seja uma zona de fácil visualização e acesso, as alterações que vão acontecendo passam muitas vezes despercebidas, ou não lhes é dado o devido valor fazendo com que, as patologias malignas sejam na maior parte das vezes, reconhecidas tardiamente não permitindo outro tipo de atuação senão paliativa. Uma das desordens que acontecem com recorrência é o Líquen Plano (LP). Tratando-se de uma patologia crónica, mucocutânea e autoimune, relativamente comum, que afeta maioritariamente as mulheres numa proporção de 3:2 para os homens, em idades compreendidas entre os 50 e 70 anos de vida. É uma dermatose caracterizada por ter potencial de recorrência, não sendo, contudo, contagiosa. O Líquen Plano poderá atingir a pele, couro cabeludo, unhas, mucosa genital e a cavidade oral. Na cavidade oral, designa-se como Líquen Plano Oral (LPO) e afeta a mucosa oral em 70% dos casos, sendo descrita pela Organização Mundial da Saúde (OMS), como sendo uma lesão prémaligna. Tendo em conta estes fatores, o objetivo deste trabalho é a análise da potencialidade de malignidade do LPO, uma vez que, existem distintas vertentes de entendimento e caracterização do mesmo. Para tal foi utilizada uma metodologia qualitativa de natureza bibliográfica com a aplicação de um conjunto de dados de pesquisa em websites, artigos de revistas e obras de índole cientifica, permitindo assim a realização de uma revisão bibliográfica.

Small bowel pseudomelanosis and oral iron therapy

Small bowel pseudomelanosis is a rarely reported clinical entity characterized by brown pigmentation of small bowel mucosa. The authors describe two cases, both with iron deficiency anemia, one of an 81-year-old female patient submitted for capsule endoscopy that revealed a brown pigmentation of all small bowel mucosa and another of an 81-year-old male whose retrograde double-balloon enteroscopy revealed a diffuse brown pattern of small bowel mucosa. Ileal biopsies confirmed intense iron deposition in the macrophages of the lamina propria. Both patients were on oral iron therapy and the second one had a previous double-balloon enteroscopy, 2 years earlier, which revealed only ileal angiodysplasias. These two cases demonstrate the importance of two new endoscopic methods for diagnosis of small bowel pseudomelanosis, the rarity of such an entity and its close relation with oral iron therapy.

Is Aphtous Oral Ulceration Biopsy always Useless?

Objective: To report a case of Behçet’s disease whose diagnosis was only confirmed thanks to an oral aphthous lesion biopsy. Materials and methods: Conventional histopathological analysis of a biopsy of an aphthous oral lesion that had appeared two days previously. Results: A small vein vasculitis with eosinophil and neutrophil granulocytes was evidenced. Conclusion: The presence of a small vein vasculitis was here strongly in favour of Behçet's disease, whereas such a diagnosis was not confirmed according to the International Study Group’s criteria.

Trèlat's beads as oral manifestations in patients with HIV/TB

Tuberculosis (TB) is a contagious infectious disease caused by Mycobacterium tuberculosis (Koch's bacillus). Co-infection with human immunodeficiency virus (HIV) and TB has reached a significant importance as a public health problem and this association has been recognized as the most significant event that changed "the balance between man and Koch's bacillus" in the last century, and has a large contribution to the risk for disease spreading. Tuberculosis has two main standard categories of clinical manifestations: primary and secondary. Primary TB is responsible for the initial infection with lungs being the involved organ. Oral lesions are observed as a secondary TB clinical manifestation with most frequent sites being hard and soft palate, tongue, lips, gums, tonsils, and salivary glands. A case of classical TB lesions in the oral cavity is reported, and the importance of a correct diagnosis through careful history taking is emphasized. Treatment selection needs to be done assertively, with great determination and building a link between patient and treatment protocol, in order to promote patient's adherence.
