Micronuclei (MN) originate from chromosome fragments or whole chromosomes that lag behind at anaphase during cell division can occur due to excessive exposure to harmful agents, defects in mitosis and / or DNA repair process. The study evaluated the frequency of micronuclei in cytological samples after daily use of alcohol -based mouthwash mouth in smokers and non-smokers. We assessed 30 subjects, aged between 17-42 years and established as exclusion criteria: alcohol consumption; periodontal disease; systemic diseases that may interfere with the integrity of the oral mucosa; individuals with medical or pharmacological history that affect the performance of the study, family history of malignancies. For smokers the inclusion criterion was a minimum consumption of 20 cigarettes / day, and the contrast required for non-smokers. The sample was divided into 02 experimental groups: Group 1 Smokers and Group 2 Non-Smokers, both groups performed mouthwash (alcohol 21,6%) with Listerine® Defense of Teeth and Gums for 04 weeks cytological collection were performed on buccal mucosa and portion median border of the tongue, one for initial, week 0 control, and subsequent three weeks with continued use of mouthwash. The collected material was stained by specific staining Feulgen / Fast Green. The analysis of 3000 cells / individual was performed by light microscopy statistics used Kruskal- Wallis and Mann-Whitney tests for frequency MN. The frequency of micronuclei in buccal mucosa was 1.6 ± 1.75 and 1.46 ± 2.06 for the site language to Group 1 Smokers of showing a slight increase compared with Group 2 Non-smoking, which showed a variation of 1.2 ± 1.53 for the buccal mucosa site and 0.86 ± 1.41 for the site language. However, this difference was not statistically significant. The results suggest that alcohol-based mouthwash tested is not an inducer of genotoxic changes, thus not changing the frequency...

Introduction: The study of graft donor sites, whether from the anatomical, physiological or morphological point of view, has become a topic of current interest, due to the increasing number of patients needing facial bone reconstruction for various reasons. Purpose: In view of the need to constantly improve surgical techniques for autogenous bone graft harvesting, still considered the best choice for facial bone reconstruction, this paper describes an anatomical study on dry skulls in order to evaluate the average thickness of the parietal bone. Material and Methods: Measurements of this bone were taken with a goniometer, at four previously defined points, in the region that is often used as a donor site, in 49 dry skulls (98 parietal bones). The results were evaluated using the T test. Results: Thickness was measured at four predetermined points. The mean values (Point A = 4898mm, B = 4517mm, C = 6185mm, D = 4280mm) show that the bone can be even thinner than previously reported in the literature in other studies of the same nature. The largest bone thickness is in the medial and posterior region. Conclusion: A knowledge of these anatomical characteristics is helpful in preventing possible surgical complications, as well as making it safer for the surgeon to remove this graft and providing more information on whether or not to indicate this region as a bone graft donor site.

The osteomas are benign rare neoplasms, generally asymptomatic which are characterized by the proliferation of a compact or spongy bone. When they are situated in the maxillofacial area, they affect mainly the mandible, the frontal bone and the paranasal sinus. We have described the case of a female caucasian patient who presented an increased volume in the posterior region of the oral vestibule on the left side. During the clinical examination an oral lesion was observed in the region of the left ramus of mandible. This lesion was motionless, consistent, and painless when palpated. In the image obtained from the computed tomography cone–beam (CBCT), we could observe an hyperdense, cylindrical region, with well defined borders, located in the medial surface of the left ramus of mandible, right below the mandibular notch. Based on clinical data and in the obtained images, we could confirm the presence of the peripheral osteoma in the left side of the ramus of mandible region.

The aim of this study was to review the prevalence of canine splenic disorders by means of a retrospectiveanalysis of histological diagnosis after splenectomy. The results were confronted with laboratory findings, clinical signs and presence of cardiac arrhythmia and hemoperitoneum, in an attempt to establish the differentialdiagnosis of splenomegaly. One hundred and nine dogs assisted at the Veterinary Hospital of theSchool of Veterinary Medicine and Zootechny, University of São Paulo, were included in the retrospectivestudy, between 2002 and 2009. The average age was 10 years old ± 3, with no sexual predilection. Mixedbreed dogs was the most affected kind, and average weight was 22 kg ± 13. Overall, 52% (57/109) of dogswere splenectomized due to non-neoplastic diseases and 48% (52/109) to neoplastic diseases. Among thelatter, the most common diagnosis was hemangiosarcoma (28 dogs; 54%). Most frequent clinical signs includedanorexia, lethargy and vomiting. Results showed that dogs with low red blood cell count, low hematocritvalues and/or hemoperitoneum were more likely to have splenic malignant neoplasm. On the otherhand, sex, breed, size, age, cardiac arrhythmia and other laboratory parameters were not determining factorsin the differentiation of splenomegaly.

O carcinoma espinocelular é uma das quatro neoplasias malignas que mais acomete gatos, principalmente os de pele clara e que residem em países tropicais onde a incidência de raios solares é intensa. O tratamento cirúrgico é o mais indicado, mas nem sempre é possível de ser realizado seja pelo estágio avançado do tumor, pela sua localização ou por opção do proprietário que não quer ver seu animal mutilado. O objetivo desta revisão sistemática foi verificar a eficácia da quimioterapia com ou sem associações terapêuticas para o tratamento do carcinoma espinocelular superficial, multicêntrico e de cabeça e pescoço em gatos. Os melhores resultados para o tratamento do carcinoma espinocelular superficial foram observados com a aplicação intralesional do quimioterápico associado à radioterapia ou à eletroterapia, para o tipo multicêntrico faltam trabalhos sobre o assunto e o único encontrado não apresentou resultados satisfatórios. No caso do carcinoma espinocelular de cabeça e pescoço que alberga o pior prognóstico, a terapia multimodal com associação de quimioterapia, radioterapia e excisão cirúrgica demonstrou ser eficiente. Mais estudos sobre o assunto devem ser realizados utilizando um número maior de animais e com um tempo de seguimento mais longo
