Prevalence of oral lesions in 25 years of Oral Cancer Prevention campaigns in Paraná State, Brazil, 1988 to 2013

Introduction: Epidemiological studies add up as a large area of scientific research and play an important role revealing the prevalence of the several diseases in the place where they applied. Public and health professionals have become more aware of the importance of oral mucosal lesions. Objective: To determine the frequency of the oral lesions and determinate the epidemiological profile of patients attending the prevention of oral cancer campaigns in the state of Paraná, Brazil, between 1988 and 2013. Material and methods: A prospective study was conducted evaluating 25 years of oral cancer prevention campaigns in the state of Paraná, Brazil, between 1988 and 2013. All patients were evaluated in a systematic way and were older than 30 years, answering one questionnaire with data relating to harmful health habits, family history of cancer, family income, frequency of visits to dentists and knowledge on the subject. Results: A total of 22,300 patients were evaluated during the 25 years of projects and 3,731 had oral lesions, while 18,569 patients had no oral alterations during the evaluation. Among those patients, 13779 (61.78%) were female and 8521 (38.78%) were male, 843 (22.59%) were smokers, 578 (15.49%) used alcohol and in 1386 (37.14%) had the habit of using yerba mate. The prevalence of lesions occurred as follows: 533 (14.28%) cases of lesions with aspect of leukoplakia, 1095 (29.34%) inflammatory lesions, 1934 (51.83%) of traumatic origin and 169 (4 5%) classified as other. Conclusion: The campaigns have brought benefits to the health of the elderly population but it is still not enough to make up for low levels of oral lesions appearance. Education of the population should in this way be approached more seriously and effectively.

Prevalence of oral lesions in elderly patients on oral cancer prevention campaigns in Paraná state Brazil 1989-2013 / Prevalência de lesões orais em pacientes idosos atendidos em campanhas de prevenção de câncer bucal no estado do Paraná, Brasil entre 1989 - 2013

Objective: recently, there has been a rapid aging process of the world population. Despite of a longer permanence of natural teeth and a reduction of oral diseases caused by the improvement of life conditions and the provision of health care, the prevalence of oral diseases in the elderly is still considered significant. Therefore, the aim of this study is to evaluate the epidemiological profile of elderly patients (above 60 years old) attended in 25 years of campaigns oral cancer prevention in the Paraná state, Brazil, between 1989 and 2013. Material and Methods: Patients, volunteers, were evaluated during 25 years of oral cancer prevention by the campaign team and all patients were evaluated in a methodical way with inspection of all intra-oral areas. Results: a total of 22,909 patients were attended during the 25 years of projects. Of these, 6,134 were older than 60 years old, with appearance of 1,523 oral lesions during the examination and 4,611 patients had no oral alterations during the dentist evaluation, among those were found injuries by traumatic origin, inflammatory lesions and others types of injury. Conclusion: it is clear the necessity for specialized care and active surveillance of these patients, since it is a consensus in the literature that the best treatment is early diagnosis. It is also necessary the development of epidemiological studies of the elderly population, which are scarce and difficult to elaboration of plans for effective action to meet the specific demands of this age group.

Objetivo: a população mundial atualmente sofre com um rápido processo de envelhecimento. Apesar de uma maior permanência dos dentes naturais e da redução de doenças bucais causadas pela melhoria das condições de vida e da prestação de cuidados de saúde, a prevalência de doenças bucais em idosos ainda é considerado significativa. Portanto, o objetivo deste estudo é avaliar o perfil epidemiológico dos pacientes idosos (acima de 60 anos) que foram atendidos em 25 anos de campanhas de prevenção do câncer de boca no estado do Paraná, Brasil, entre 1989 e 2013. Material e Métodos: Os pacientes foram selecionados voluntariamente e avaliados durante 25 anos de prevenção de câncer bucal pela equipe participante, os quais foram avaliados de forma metódica com a inspeção de todas as áreas intra-orais. Resultados: um total de 22.909 pacientes foram atendidos durante os 25 anos de projetos. Destes, 6.134 tinham mais de 60 anos, com presença de 1.523 pacientes com lesões orais durante o exame e 4.611 pacientes sem alterações orais durante a avaliação do dentista. As lesões encontradas tinham origem traumática, inflamatórias e outras. Conclusão: é evidente a necessidade de atendimento especializado e da busca ativa desses pacientes, uma vez que é um consenso na literatura de que o melhor tratamento de lesões orais é o diagnóstico precoce. Também é necessário o desenvolvimento de estudos epidemiológicos da população idosa, que são escassos e difíceis de elaboração assim como a realização de planos de ação eficazes para atender às demandas específicas desta faixa etária.

[Oral cancer surgery and oral cutaneous fistulas: risk factors]. / Fístulas orocutâneas após cirurgia de câncer da cavidade oral: fatores de risco.

OBJECTIVE: To quantify the oral cutaneous fistulae after surgery and to identify possible risk factors. METHODS: A retrospective study, interesting patients that were submitted to surgery, with a two years minimum post-operative follow up. The considered variables were: sex, concomitant diseases, tabacco and alcohol use, the anesthesic and pulmonary risks, clinical stage, cervical linphadenectomy, pre or postoperative radiotherapy, accidents during the surgery, wound infection and or hematoma, pulmonary infection, surgery and reconstruction extension. RESULTS: In 159 patients, oral cutaneous fistulae occurred in 48 patients (30,3%): Patients stage T1 in 26,6 %,T2 in 1,8 %,T3 in 16%, and T4 in 40,3% (p=0,0138). The cases N+ developed fistulae in 22.9%, (N2c with 42,8%, (p=0,0136), those with preoperative radiotherapy in 63,6% (p=0,0346) Those with wound infection in 47,3% (p=0,0146), and those with wound deiscense in 53,7 % (p=0,0030). The fistulae rate was of 60% in the regional mucocutaneous flaps reconstruction cases, 39,2% in the myocutaneous ones and 12,5% of microsurgery ones (p=0,0286). CONCLUSION: The general rate of oral cutaneous fistulae was 30,3%. The significant factors were: T stage, cervical linphadenectomy, pre or postoperative radiotherapy, wound infection and deiscense, and the use of flaps.

Accuracy, sensitivity and specificity of fine needle aspiration biopsyin salivary gland tumours: A retrospective study

Objective: The aim of this study was to evaluate the diagnostic accuracy, sensitivity and specificity of fine needleaspiration biopsies (FNAB) of salivary gland tumours performed at the Erasto Gaertner Hospital over the courseof a four year period. Study design: A retrospective study was carried out between 2001-2005 to review thecases of patients with salivary gland tumours who had undergone pre-operative FNAB and had been diagnosedduring post-operative histopathology examination. Results: A total of 106 cases of salivary gland tumours wereconsidered for this study, but 27 cases (25.5%) of the samples were considered unsatisfactory for analysis. Thesensitivity, specificity and accuracy were calculated considering only the 79 benign and malignant cases in whichFNAB provided sufficient samples for analysis. Based on these data, the value of sensitivity was 68.2% (15/22),specificity was 87.7% (50/57), accuracy was 82.3% (65/79), positive predictive value was 68.2% (15/22) and negativepredictive value was 87.7% (50/57). Conclusions: Despite the high rate of inadequate samples obtained in theFNAB in this study, the technique offers high specificity, accuracy and acceptable sensitivity (AU)

Doença de Madelung / Madelung's disease

Doença de Madelung ou lipomatose simétrica múltipla é uma doença rara, que é caracterizada por acúmulo de gordura näo encapsulada, geralmente localizada simetricamente ao redor do pescoço e ombros. A etiologia é desconhecida, mas é freqüentemente observada em pacientes com história de alcoolismo crônico e é acompanhada por anormalidades metabólicas. Os autores apresentam um caso de lipomatose cervical associada a polineuropatia e alcoolismo. A remoçäo cirúrgica do tecido adiposo por lipectomia ou lipoaspiraçäo é terapia paliativa, já que ele näo é encapsulado, a recorrência é comum

Fisioterapia pré-operatória em pacientes candidatos à cirurgia por neoplasia de cabeça e pescoço / Pre-operatory physical therapy in candidates for surgery of head and neck cancer

A partir da correlaçäo entre a incidência de neoplasias de cabeça e pescoço e o tabagismo, e deste com as alteraçöes funcionais semelhantes às descritas na Doença Pulmonar Obstrutiva Crônica (DPOC), este trabalho tem por objetivo avaliar a eficiência do tratamento fisioterápico pré-operatório na minimizaçäo destas alteraçöes, que na maioria das vezes estäo correlacionadas com as complicaçöes pulmonares destas cirurgias. Foram estudados 46 pacientes candidatos à cirurgia por neoplasia de cabeça e pescoço, realizando-se avaliaçöes de Pressäo Inspiratória Máxima (PImáx), Ventilaçäo Voluntária Máxima em percentual para o teórico previsto (VVM porcento), índice de performace de Karnofsky e exame muscular respiratório, antes e após a realizaçäo de 10 sessöes da seguinte rotina fisioterápica: inaloterapia por impactaçäo associada a Padräo Muscular Respiratório (PMR) 1:1 e carga linear pressórica. A análise estatística dos dados comparados pareadamente pré e pós-tratamento mostrou diferenças significativas em todos os parâmetros de avaliaçäo muscular. Conseqüentemente podemos concluir que o tratamento fisioterápico pré-operatório como rotina proposta é eficaz na minimizaçäo das desordens funcionais ocasionadas pela DPOC.
