A colonização de nasofaringe por Staphylococcus aureus, resistente à meticilina (Methicillin-resistant S.aureus - MRSA), é comum em pacientes criticamente doentes, mas seu significado prognóstico não é inteiramente conhecido. Realizou-se estudo de coorte retrospectivo com 122 pacientes de uma unidade de terapia intensiva que realizaram triagem semanal para colonização por MRSA. Os desfechos de interesse foram: mortalidade geral e mortalidade por infecção. Diversas variáveis de exposição (gravidade, procedimentos, intercorrências e colonização nasofaríngea por MRSA) foram analisadas em modelos univariados e multivariados. Fatores significativamente associados à mortalidade geral ou por infecção foram: APACHE II e doença pulmonar. A colonização por MRSA não foi preditora de mortalidade geral (OR=1,02; IC95%=0,35-3; p=0,97) ou por infecção (OR=0,96; IC95%=0,33-2,89; p=0,96). Os resultados sugerem que, na ausência de fatores de gravidade, a colonização por MRSA não caracteriza pior prognóstico.

The treatment of choice for these cases was surgical removal. In both cases the diagnostic was infiltrative follicular carcinoma of thyroid. The first animal did not present a good recovery after the surgery, and died four hours after the procedure. In the second case, the diagnosis was more precocious and antineoplastic chemotherapy was used after the surgery. At the time of submission of this manuscript, this animal had survived for foully months. Currently, there is a need to define the protocols of chemotherapy to avoid relapse and metastases, in order to increase the life expectancy in dogs with thyroid neoplasm.

OBJECTIVES: Pleomorphic adenomas are the most frequent type of epithelial salivary gland neoplasms, and their malignant counterpart, the carcinoma in pleomorphic adenomas, is much less common. Beta-catenin is a cell adhesion molecule associated with the invasion and metastasis of carcinomas of the head and neck, esophagus. The objective of this study was to detect the expression of beta-catenin in pleomorphic adenomas, carcinomas in pleomorphic adenomas and normal salivary glands to discuss its role in the development of these two lesions. STUDY DESIGN: The expression of beta-catenin (BD Transduction Laboratories) was analyzed by immunohistochemistry in formalin-fixed, paraffin embedded specimens by the avidin-biotin-peroxidase complex method in 16 pleomorphic adenomas (12 from minor salivary glands), 3 carcinomas in pleomorphic adenomas (all from palate) and 10 normal salivary glands as control group (5 from major and 5 from minor salivary glands). RESULTS: All cases of glands, adenomas and carcinomas in pleomorphic adenomas have membranous and cytoplasmic immunostaining. Nuclear beta-catenin immunostaining was not observed. The antibody presented a fine granular arrangement in the cytoplasm and cellular membrane of duct and acinic cells. Higher beta-catenin index rates were seen mainly in salivary gland ducts and in ductal structures in the adenomas and carcinomas in pleomorphic adenomas. There was protein loss in pleomorphic adenomas and cytoplasmic accumulation in carcinoma in pleomorphic adenomas. CONCLUSIONS: The present study showed participation of the loss of beta-catenin adhesion molecule in the development of pleomorphic adenoma, and that the cytoplasmic accumulation of the molecule takes part in the malignant transformation of the pleomorphic adenoma into carcinoma in pleomorphic adenoma.

Introduction and Objective: Microorganisms are responsible for multiple infections and pathologies; this is why it is important to control microbes that can be found in the triple syringe used for irrigation in different dental procedures. The aim of this study was to identify cultivable species of microbes (fungus and bacteria) found in some dental units water lines of a private dental clinic from Medellín, Colombia. Materials and Methods: Random samples were taken from 11 chairs from a total of 89; a sample of water of 500ml was collected from the triple syringe of each selected chair. The study aim to search for the presence of total coliforms, filamentous fungi and leavened Results: the average presence of microorganisms was between 40CFU and more of 200 CFU. Microorganisms such as Aeromona salmonicida, Actinobacilus sp and Pseudomona maltophil were isolated. No total coliforms neither fecal coliforms were found. Conclusions: the high levels of contamination suggest that there is a mature biofilm in somewhere of the dental unit water line, but the absence of total and fecalis coliforms suggest that the water had been treated.

The condylar hyperplasia is an acquired development anomaly, rare, characterized by an excessive and progressive growing, affecting neck, condilar head, body and the mandible bough, provoking an important facial asymmetry. In the article we present a case of male patient, 22-years-old, reclaiming of painful sintomatology in the region of temporomandibular joint and severe facial asymmetry. It was instituted an orthodontic-surgical treatment by means of orthognathic combined surgery and high condilectomy. After six years of post-surgical controlling, the patient is now in a good shape, without recurrence of facial asymmetry and condylar hyperplasia.

The aim of this study was to evaluate the local anesthetic solution, composed by Prilocaine 3% and felipressin 0,03 UI/ml, influence on the alveolar repair process in rats after dental extraction. This research was previously approved by the Ethic Committee in Research of the Masters Degree Program in Oral and Maxillofacial Surgery of the Marília University (UNIMAR), Marília, São Paulo, Brazil. It was an experimental, randomly controlled study, with bifactorial analysis (group control versus experimental group, in function of the postoperative times (2 X 4)). For the accomplishment of this study 32 rats were used (Rattus norvegicus, albinus, Wistar), males, adults, weighing between 280 and 320 grams. The animals were selected and divided into Group I (control) and Group II (Citocain 3%® - Prilocaine 3% with felipressin 0,03UI/ml) with 16 rats each; being four animals of the Group I and four of the Group II, destined to the euthanasia in the postoperative periods of 3rd, 7th, 15th and 24th days. The histological analysis with base in the developed methodology, allowed us to conclude that the anesthetic solution of Citocain 3%® applied with gauze compress on the surgical dental wound, produced tissue events that committed the basic biological principles, that are responsible for the regeneration of the gingival epithelium and the alveolar process repair in rats. The Group I presented better results in the alveolar repair when compared to the Group II.

The oral rehabilitation with osseointegrated implants is a well-documented treatment with high rate of success. Nevertheless, demands related to treatment time and surgical technique began to appear. In this context, the procedure of immediate loading in which the dental prosthesis is placed right after implant surgery has become a constant practice. Although immediate loading has been an important advance, minimally invasive procedures, such as implant placement without raising a mucoperiosteal flap (flapless) are increasingly being performed. Association of immediate loading with the flapless technique improves acceptance by patients and professionals, because no suturing is required. Moreover, it reduces swelling, bleeding during and after surgery, postoperative pain, surgery time, discomfort and hematoma, as well as the need for postoperative medication. These characteristics ease the stages of rehabilitation soon after implant placement, cooperating with prosthodontist's work. Thus, the proposal of this study is to present a clinical case of oral rehabilitation with osseointegrated implants and fixed prosthesis in both arches, in which the flapless technique was applied, followed by immediate loading. It will discuss the diagnosis, prosthetic planning, surgical/prosthodontic procedures and follow-up for 20 months.

This study focused on the validation of the Spanish version of the UNESP-Botucatu multidimensional composite pain scale to assess postoperative pain in cats. The original scale in Portuguese was translated into Spanish by two independent translators, and summarised in one version by a third individual. The summarised version was back-translated and minor adjustments were made. The scale was reviewed by three anesthesiologists with Spanish as their first language, and the final version was submitted to psychometric testing. Thirty cats undergoing ovariohysterectomy were video recorded during the perioperative period. Six observers from different spanish speaking countries, who had Spanish as the first language watched the videos and determined the pain scores using the Spanish version of the scale, identifying the cats that should receive analgesics. Videos were reanalysed in a different order about 2 months after the first assessment. The sensitivity to change, content and construct validity were established by the significant change in pain scores in response to surgery and analgesics. The agreement between the evaluations of the 'gold standard'(researcher that developed the scale) and the other observers confirmed the criterion validity. Inter- and intra-rater reliability, evaluated by intra-class correlation coefficient, ranged from good to very good for all scale items. The cut-off point for rescue analgesia identified by Receiver Operating Characteristic curve was > 7 with 92% of sensitivity and 91% of specificity. The Spanish version of the UNESP-Botucatu multidimensional composite pain scale is interpretable (has an optimal analgesic intervention score), valid and reliable instrument for assessing acute pain in cats undergoing ovariohysterectomy.
