Tumores de cabeça e pescoço: epidemiologia, fatores de risco, diagnóstico e tratamento

Neoplasias of the head and neck correspond to the fifth most common cancer in the world, with high mortality and morbidity. The aim of this study was to show, through a literature review, a little about the epidemiology, risk factors, diagnosis and therapy of the most common malignant tumors of each anatomical region of the head and neck. The research of the articles was made in MEDLINE data base, with a total of 52 articles used. In this review, we analyze the main aspects related to the tumors of oral cavity, pharynx, larynx and salivary glands. Almost all cancers of the head and neck affecting the mucosa of the upper aerodigestive tract are derived from squamous cells. Therefore, the risk factors between the various types of tumors are similar, with alcohol and tobacco being the main ones. To be composed of several distinct structures, the head and neck tumors deserve a diagnostic and therapeutic approach individualized for each anatomical region. Controllingthe risk factors and doing the right approach, it is expected that the incidence of cancers of the head and neck decreases, thereby reducing mortality from malignant neoplasms worldwide

Helicobacter pylori em boca: epidemiologia e associação com doenças bucais

The association of Helicobacter pylori with different gastric diseases has been continuously discussed in the literature, whereas the last 20 years a large body of publications was intended to characterize the ecological niches and habitats of this pathogen being the mouth a possible habitat for that rod. The present study aimed to discuss the occurrence of this organism as part of the supplemental or transient microbiota of the mouth. Thus, an extensive review of literature covering the period 1990-2014 was carried out with different databases, yielding 5024 articles discussing transmission and occurrence of H. pylori, in English or Portuguese. Articles were selected according to the inclusion and exclusion criteria and data were tabulated and analyzed. Despite the significant heterogeneity of the literature, it was found this microaerophilic has a worldwide distribution, even in the mouth, which behaves as a reservoir for gastric reinfection. The role of oral hygiene and periodontal disease in the distribution of this microorganism remains unclear, but most studies support the hypothesis that oral biofilms and inflammation of periodontium may facilitate the installation of this pathogen in the mouth. Studies suggest that this microorganism could collaborate as a predisposing factor for oral cancer.

Estudo retrospectivo (2007-2011) da casuística de cães com mastocitomas cutâneos atendidos em um hospital-escola

Neoplasms of mast cell origin are uncommon in most animal species. Although cases of cutaneous mastocitoma (CM) are rare in humans, it is the second most diagnosed cancer in dogs, accounting for approximately 20% of cutaneous tumors in this species. The age group most frequently affected is between eight and nine years, but it may occur in animals up to three weeks old. This study aimed to describe the epidemiological, hematological and histopathological characteristics of 73 dogs with cutaneous mast cell tumors attended between 2007 and 2011 by the Oncology Service of a teaching hospital in the state of São Paulo. Data collected included race, age, sex, weight, skin region affected, blood tests results at the first consultation and histopathological grading of dogs diagnosed with this neoplasia.

Prevalência e fatores de risco de leptospirose bovina no Estado do Maranhão

Silva F.J., Conceicao W. L. F., Fagliari J.J., Girio R.J.S., Dias R. A., Borba M. R. & Mathias L. A. 2012. [Prevalence and risk factors of bovine leptospirosis in the State of Maranhao, Brazil.] Prevalencia e fatores de risco de leptospirose bovina no Estado do Maranhao.

E-mail: fjsepi@gmail.com Prevalence and risk factors of bovine leptospirosis in the State of Maranhao were investigated. Based on production parameters that vary across different production systems, management practices, the purpose of exploitation, the average size of herds and market systems, the state was divided in four sampling circuits. The study aimed to investigate the epidemiological features of bovine leptospirosis in the State of Maranhao, in order to determine the prevalence of the infection in cattle and herds, to determine the occurrence of serovars of Leptospira spp., to identify risk factors associated with leptospirosis in cattle and to differentiate the livestock circuits itself regarding the prevalence of leptospirosis. The survey was conducted in 136 herds in the circuit I, in which 841 >= 24 months old females were analyzed; 238 in the circuit II and 2,582 females were analyzed; 122 in the circuit III and 869 females were analyzed; 77 in the circuit IV and 540 females were analyzed; a total of 573 herds and 4,832 females were analyzed. The presence of antibodies against Leptospira spp. was verified by microscopic agglutination test (MAT). Of the 4,832 cows examined, 1,904 (35.94%, CI 95% = 33.01% -38.98%) were positive. Of the 573 herds, 380 (64.81%, CI 95% = 61.10% -68.35%) were positive. Serovars Hardjo and Wolffi were the most frequent in the state. The circuit III showed the lowest prevalence of leptospirosis in all comparisons. The variables presence of horses (p = 0.000), presence of capybaras (p = 0.034) and herds with up to 32 adult females (p = 0.002) were identified as risk factors for leptospirosis.
