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.

Aggregatibacter actinomycetemcomitans em pacientes com síndrome de down: influência da condição periodontal e higiene bucal

Patients with Down syndrome have varying degrees of mental retardation, physical and motor, and apparently are more susceptible to infectious diseases. Thus, the present study aimed to evaluate the occurrence of Aggregatibacter actinomycetemcomitans in saliva and subgingival biofilms and above of children and adolescents with Down syndrome and analyze the influence of diet, socioeconomic and cultural factors and periodontal condition. After assessing the socio-economic and behavioral, were collected clinical specimens, which were transported to the laboratory of Microbiology and Immunology FOA-UNESP for detection of microorganisms by molecular method and periodontal conditions were evaluated according to the Periodontal Screening Index and Recording. The control group consisted of individuals without the syndrome. The results were analyzed by chi-square test for proportion analysis of variables with three or more categories, or the Mann-Whitney test. The data analysis of this study showed that the occurrence of A. actinomycetemcomitans ranged from 0.0% to 25.0%, both in the group of patients with Down syndrome, as for the control group and this was not affected by socioeconomic characteristics of the target population, either by oral hygiene standards

Infecções odontogenicas: relato de caso clínico e implicações terapêuticas

Acute infections maxillo-facial are of great importance, both for its high population, as the risk of complications. The aim of this study was to present a clinical case of extensive odontogenic abscess in a patient of 31 years of age attended the Service of Surgery and Maxillo-Facial, Faculty of Dentistry of Araçatuba - UNESP in Araçatuba, SP. Complications of infections odontogências although infrequent can lead the patient to death.

Depressão e suicídio na adolescência: representações sociais e indicadores de risco

Adolescence is a period of physical, biological and psychological changes as well as its time for reflection of the perspectives and social functions that are not defined yet. In addition to the characteristics of this period also included the family and socio-economic aspects such as parental separation, domestic violence, poverty, among others, yielding often, insecurity and confusion feelings, contributing to the case of depression in many cases, each increasingly recurrent and early at this stage in human development. The present study, thus, aimed to investigate the indicators of risk and vulnerability in adolescents to depression, especially those in social context, highlighting the social representation of the same against the disorder, since these guiding this research, the indication of factors contributing influence the etiology of depression in this period. Be consulted on the basis of VHL-PSI, articles related to depression in adolescence, published between the years 2004 to 2014. Observe that adolescents with negative perception of the social context in which the live, are more likely to develop depression, highlighting the importance of healthy social and family relationships for mental health.

Associação entre a doença periodontal e doenças sistêmicas crônicas: revisão de literatura

Periodontal disease has been increasingly associated as a supporting factor, and even a precursor to some systemic diseases. Just aim of this paper was to analyze by reviewing the literature, the possible mechanisms involved in the etiopathogenesis of periodontal disease that are common to the current systemic diseases such as obesity, atherosclerosis, diabetes and rheumatoid arthritis. The articles were analyzed with in the publication period of the years 2006 to 2011 and were surveyed in the databases PubMed, LILACS and SciELO. Of a total of 907 articles found by searching the indices and their associations, were selected by inclusion criteria 93 articles. For the preparation of this literature review, only 24 articles were selected because they are based on inflammatory mechanisms, metabolic and infectious, where the considerations for the strongest associations in the literature. This literature review reinforces the association of periodontal disease with systemic diseases analyzed due to presence of inflammatory and immunological mechanisms and similar synergism betwen the two diseases, but some hypotheses still need further clarification. The professional should stick to recent discoveries associations to promote periodontal treatment in preventing the development of systemic diseases, as well as in maintaining the systemic health of patients already suffering from chronic systemic diseases.

Desenvolvimento de bebida láctea potencialmente probiótica carbonatada: características físico-químicas, microbiológicas e sensoriais

The goal of this work was to develop a strawberry fl avored dairy beverages carbonated and fermented with potential probiotic bacteria. Four formulations of dairy beverages were elaborated: Control (BL); Fermented (BLF); Carbonated (BLC) and Carbonated Fermented (BLFC). In samples submitted for carbonation, a carbonator was used for the carbon dioxide (CO2 ) gas injection dissolved in drinking water and the cultivation consisting of lactic bacteria Lactobacillus acidophilusLA-5®, Bifi dobacterium BB-12® and Streptococcus thermophilus (Biorich, Chr. Hansen) was employed on the fermented samples. The samples were characterized by physical and chemical, microbiological and sensory parameters. The BLC sample showed the presence of yeasts and coliform counts, but the counts indicated that it was suitable for consumption in 28 days time. The BL presented average coliform counts above the limit established by the law after 21 days of refrigerated storage. The presence of lactic bacteria and CO2 and their effects on lower proteolysis indexes, lower pH values and higher acidity values were correlated with signifi cant inhibitory effect of contaminated microorganisms in the BLF and BLFC. The carbonation was not stimulatory for the growth of lactic crops, mainly in the genus Bifi dobacterium spp. and Streptococcus spp. The BLF drink presented greater sensory acceptance and purchase intention test results, however the carbonated beverage presented positive results, with mean values greater than 50% in the acceptance tests with potential inclusion as sensory differential in dairy beverages. Just BLFC drink was considered potentially probiotic, by presenting minimum counts of Lactobacillus spp. during storage. Further studies should be conducted with the technology of carbonation, since it has been proven the correlation of the presence of CO2 with inhibitory effect of contaminated microorganisms and lower physical and chemical changes of dairy beverages.

Análise de desempenho dos codecs suportados pelo Asterisk com e sem criptografia

The main objective is to analyze the performance of some codecs supported by Asterisk with and without encryption using RTP and SRTP, respectively, providing important data for decision-making in the implementation of a VoIP system with Asterisk. Thus, it is possible to realize both codecs as the protocol can be chosen depending on the application, or the system's main feature is the speed packet switching, security level or lower tolerance for unsuccessful calls. For this, tests were made with the codec with and without the use of cryptography to obtain some findings on the use of the same, giving more attention to the response time for the start of a call.

Reconstrução de maxila severamente atrófica via enxerto ósseo autógeno de calota craniana: descrição de técnica

Bone reconstructions are traditionally conducted with autogenous grafts harvested from intra- or extra-oral donor sites to reestablish the lost bone volume for further implant-prosthetic rehabilitation. The calvarial bone has been studied as an excellent donor site in large atrophic situations, presenting low resorption rates, as well as complications and minimal morbidity. The hospitalization time is short, with low pain levels, short functional limitations, and invisible scars. The skull microarchitecture is predominantly cortical in the presence of growth factors that demonstrate their osteogenic, osteoinductive, and osteoconductive abilities resulting in low resorption rate and high predictability when compared to the iliac crest. Dural lacerations, extra and subdural bleeding, cerebrospinal fluid leakage, and brain damage have been minimized due to the development of surgical technique. The delimitation of diploe, preserving the internal skull cortex before osteotomy at the donor made it possible to reduce accidents and complications. The aim of this paper is to show a technical and to discuss aspects of the use of calvarial bone in the reconstruction of severely atrophic maxilla for oral rehabilitation with osseointegrated implants.
