    TCC (graduação) - Universidade Federal de Santa Catarina. Centro de Ciências da Saúde. Odontologia.A boca humana, em condições fisiológias, contém um grande número de bacterias patológicas e não patológicas. Quando há um desequilíbrio entre a microbiota e as defesas do hospedeiro podem ocorrer diversas doenças, entre elas a doença periodontal; uma enfermidade extremamente comum na população mundial. Também conhecida como periodontite, ela representa um grupo de doenças inflamatórias de origem infecciosa e multifatorial que destrói os tecidos de suporte do dente. A prevenção e o tratamento dessa enfermidade são objetos de muitos estudos devido a sua extrema importância na Saúde Pública. Seu tratamento baseia-se em raspagem e alisamento radicular a campo aberto ou fechado associado à constante instrução de higiene oral e motivação do paciente. Esta é a terapia periodontal convencional, que na maioria dos casos possui êxito, entretanto nos casos em que a doença periodontal não regride, outras estratégias de tratamento são adotadas, entre elas o uso adjuvante de antibióticos. Este trabalho teve como objetivo revisar a literatura relacionada ao uso sistêmico de antibióticos no tratamento da doença periodontal. O estudo buscou analisar o uso de tetraciclina, amoxicilina e metronidazol, azitromicina, eritromicina e clindamicina sistêmicos como uso adjuvante do tratamento da doença periodontal. Apesar de ainda não haver um consenso quanto à dosagem, o intervalo entre as administrações e principalmente quanto ao tempo total do tratamento com antiinfecciosos sabe-se que estes são uma boa opção nos casos em que o tratamento periodontal convencional não consegue controlar a doença. Sendo apontado na literatura a associação de amoxicilina com metronidazol, e a tetraciclina como as melhores opções nesses casos. Palavras chave: doença periodontal; antibióticos; tratamento.The human mouth in physiology conditions, contains a large number of pathological and non-pathological bacteria. When there is an imbalance between the microbiota and host defenses can occur several diseases, including periodontal disease; an extremely common disease in the world population. Also known as periodontitis, it represents a group of inflammatory diseases of infectious and multifactorial origin which destroys tooth supporting tissues. The prevention and treatment of this disease are the subject of many studies because of its extreme importance in Public Health. Your treatment is based on scaling and root planing to open or closed field associated with the constant education of oral hygiene and patient motivation. This is the conventional periodontal therapy, which in most cases has successfully, however where periodontal disease does not regress, other treatment strategies are adopted, including adjunctive antibiotics. This study aimed to review the literature related to the systemic use of antibiotics in the treatment of periodontal disease. The study investigates the use of tetracycline, metronidazole and amoxicillin, azithromycin, erythromycin, and clindamycin as systemic adjunctive treatment of periodontal disease. Although there is still no consensus as to dosage, dosing interval and particularly for the total treatment time with anti-infective know that these are a good choice where conventional periodontal treatment can not control the disease. As pointed out in the literature the combination of amoxicillin and metronidazole, and tetracycline as the best options in such cases. Keywords: periodontal disease, antibiotic, treatment

    Recent multivariate analyses of brain data have boosted our understanding of the organizational principles that shape neural coding. However, most of this progress has focused on perceptual visual regions (Connolly et al., 2012), whereas far less is known about the organization of more abstract, action-oriented representations. In this study, we focused on humans{\textquoteright} remarkable ability to turn novel instructions into actions. While previous research shows that instruction encoding is tightly linked to proactive activations in fronto-parietal brain regions, little is known about the structure that orchestrates such anticipatory representation. We collected fMRI data while participants (both males and females) followed novel complex verbal rules that varied across control-related variables (integrating within/across stimuli dimensions, response complexity, target category) and reward expectations. Using Representational Similarity Analysis (Kriegeskorte et al., 2008) we explored where in the brain these variables explained the organization of novel task encoding, and whether motivation modulated these representational spaces. Instruction representations in the lateral prefrontal cortex were structured by the three control-related variables, while intraparietal sulcus encoded response complexity and the fusiform gyrus and precuneus organized its activity according to the relevant stimulus category. Reward exerted a general effect, increasing the representational similarity among different instructions, which was robustly correlated with behavioral improvements. Overall, our results highlight the flexibility of proactive task encoding, governed by distinct representational organizations in specific brain regions. They also stress the variability of motivation-control interactions, which appear to be highly dependent on task attributes such as complexity or novelty.SIGNIFICANCE STATEMENTIn comparison with other primates, humans display a remarkable success in novel task contexts thanks to our ability to transform instructions into effective actions. This skill is associated with proactive task-set reconfigurations in fronto-parietal cortices. It remains yet unknown, however, how the brain encodes in anticipation the flexible, rich repertoire of novel tasks that we can achieve. Here we explored cognitive control and motivation-related variables that might orchestrate the representational space for novel instructions. Our results showed that different dimensions become relevant for task prospective encoding depending on the brain region, and that the lateral prefrontal cortex simultaneously organized task representations following different control-related variables. Motivation exerted a general modulation upon this process, diminishing rather than increasing distances among instruction representations

    Background In Portugal, the pollen types most implicated in respiratory allergy are grasses, olive and parietaria. The knowledge of sensitizations to molecular allergens in children and adults can contribute to better diagnosis and treatment of this pathology. Methods ImmunoCAP singleplex technology was used for molecular allergens and Phadia 250® automatic equipment. g205 (Phl p1); g215 (Phl p5b); g210 (Phl p7); and g212 (Phl p12) allergen determinations were made in 45 patients with positive grass sensitization tests. Results The majority of patients are sensitized to Phl p1 (91%) and Phl p1+/Phl p5−/Phl p7−/Phl p12− was the most dominant profile (40%). In the adult group, the IgE averages for Phl p1 were approximately 10.46, while they were 8.43 for Phl p5, 0.69 for Phl p7, and 0.06 for Phl p12. In the child group, these values were higher: 22.49, 20.23, 3.89, and 0.35, respectively. For allergens Phl p1, Phl p5, and Phl p7, these differences between the child and adult population were not statistically significant (p = 0.754, p = 0.806 and p = 0.102, respectively), but for Phl p12, a statistically significant difference (p = 0.018) was observed. Conclusions IgE antibodies Phl p1 is the most important allergic marker and sensitivities caused by Phl p12 give rise to higher IgE values in children
