O Objeto Medidas de freqüência de doença esclarece que o principal objetivo da epidemiologia é medir a frequência com que ocorrem os problemas de saúde em populações humanas e que para isso é utilizado as medidas de incidência e prevalência. Relembra que incidência se refere à frequência com que surgem novos casos de uma doença num intervalo de tempo e que a prevalência se refere ao número de casos existentes de uma doença em um dado momento. E por fim, explana sobre as frequências relativas e absolutas dessas medidas. Unidade 1 do módulo 3 que compõe o Curso de Especialização em Saúde da Família.

Dentre os causadores de impacto negativo na qualidade de vida, o trauma dental se caracteriza por ser uma injúria grave que ocorre com grande frequência em crianças e adolescentes, podendo atingir dentes decíduos (de leite) e dentes permanentes. Os dentes anteriores são geralmente os mais traumatizados, e em dentes permanentes o traumatismo é muito comum em crianças entre 7 e 12 anos, quando o desenvolvimento da raiz ainda está incompleto e o periodonto bastante resiliente, podendo mais facilmente ocasionar a avulsão dental (o dente sair por inteiro da boca, com raiz). O atendimento emergencial correto para dentes traumatizados é reconhecido como fundamental para o sucesso do tratamento final. Esta webpaletra tem a finalidade de orientar os procedimentos e conscientizar educadores, pais, responsáveis e comunidade sobre a importância das condutas imediatas adequadas frente a traumatismos, principalmente que envolvam avulsão dental, na intenção de aumentar o prognóstico favorável para estes dentes e para o sorriso futuro do paciente.

A Hipertensão Arterial Sistêmica (HAS) é a mais frequente das doenças cardiovasculares. Este trabalho teve como objetivo elaborar um plano de Intervenção com vistas a melhorar a assistência aos pacientes com Hipertensão Arterial Sistêmica no Programa de Saúde da Família (PSF) Sevilha A, do Município de Ribeirão Das Neves. Foi elaborado um plano de intervenção, usando o método de Planejamento Estratégico Situacional (PES). Para atingir o objetivo proposto, fez-se pesquisa bibliográfica para a fundamentação teórica deste estudo e do plano de intervenção aqui proposto. Foram consideradas para desenvolvimento do trabalho as referências que tiveram publicação no período de 2001 a 2014. A pesquisa foi realizada em periódicos indexados na Biblioteca Virtual em Saúde (BVS), na base de dados Scientific Eletronic Library Online (SciELO) e em páginas oficiais da prefeitura da cidade, nas bases da literatura. As três operações propostas para o enfrentamento dos "Nos Críticos" foram: aumentar o nível de informação da população sobre a doença e os fatores de riscos, viver com melhor qualidade de vida e modificar hábitos e estilos de vida, e melhorar a estrutura do serviço para o atendimento dos portadores de HAS. Com esta proposta, espera-se um acompanhamento mais efetivo dos portadores de HAS, com recursos humanos e materiais que facilitam a implementação de um projeto de Intervenção eficiente e eficaz para melhorar sua qualidade de vida.

We conducted an open, add-on study with topiramate (TPM) as adjunctive therapy in Lennox-Gastaut syndrome (LGS), to assess the long-term efficacy and safety and to evaluate quality of life (QL) measurements in the chronic use of TPM. We studied 19 patients (11 male; age ranging from 4 to 14 years) with uncontrolled seizures receiving 2-3 anti-epileptic drugs. Patients were followed up to 36 months of treatment. A questionnaire was used to query parents about QL. Seven patients completed the study at 36 months and seizure frequency was reduced > 75% in 4, and < 50% in 3 patients. Two children became seizure free for more than 24 months. Most side effects were CNS related, with the most frequent being somnolence and anorexia. These were generally transient. One patient dropped-out due to powder in the urine. None of the patients required hospitalization. At 36 months, patients' alertness (2/7), interaction with environment (5/7), ability to perform daily activities (5/7), and verbal performance (6/7) improved on TPM. We conclude that TPM may be useful as adjunctive therapy in the treatment of LGS. The efficacy of TPM was maintained in long-term treatment in more than 40% of patients, long term safety was confirmed and QL improved on TPM.

In order to evaluate the psychological variables that affect sexual dysfunction (SD) in epilepsy, where compared 60 epileptics (Group 1) with 60 healthy individuals (Group 2), through the State-Trait Anxiety Inventory (Spielberger et al., 1970), Beck Depression Inventory (Beck, 1974) and Sexual Behavior Interview (Souza, 1995). Sexual dysfunction (SD), anxiety and depression were found more frequently in Group 1 than in Group 2 and were not related to sex. Variables such as the onset duration and frequency of seizures as well as the use to medication were not associated with SD. Temporal lobe epilepsy was related to SD (p = 0.035) but not to anxiety or depression. Anxiety and depression were related to SD in both groups. Perception in controlling the seizures was closely related to anxiety (p = 0) and depression (p = 0.009). We conclude that psychological factors play an important role in the alteration of sexual behavior in epileptics and that suitable attention must be given to the control of these variables.

The individual affective-cognitive evaluations are important factors that control the way he feels the disease impact in his life. Then, the perception of seizure control is a more important factor to evaluate Quality of Life (QoL) than the illness characteristics, such as the severity, type, sickening period and seizure frequency. This study searched for the relationship among the subjective variables (perception of seizure control) and the illness characteristics to evaluate QoL. The sample consisted of 60 individuals with chronic epilepsy, aging 18 to 70 (M=37.05; SD=11.25), chosen at randon from the ambulatory of epilepsy - HC/UNICAMP, by the Questionnaire 65. The illness characteristics were not significant, except the seizures frequency, when associated to the impairment in QoL among controlled seizures and seizures with frequency higher than 10 per month (p=0.021). The perception of control was significantly associated to QoL (p=0.005).

The Orchidaceae is one of the largest flowering plants family and with a great importance to conservation. However, no survey on orchid flowers can be found in Mato Grosso do Sul. Thus, the objective of this work was to make a survey of the Orchidaceae species and of its ecology features in a riparian forest in a fragment of Floresta Estacional Semi-Decidual that belongs to the riparian forest of the Dourados River. The inventory was made by using a sweeping method for collection, and in addition to this the vertical and horizontal position of epiphytes were assessed on the hosts. For characterization of microclimate, it was used a thermohygrometer and luximeter. It was identified 17 species of 13 genera. Of the listed genera, the most abundant ones were: Acianthera, Macradenia and Capanemia. It was also noted a vertical and horizontal distribution of the Orchidaceae in relation to inverse gradient of water and light availability. Some species tended to be sensitive to height level categorization, whereas others seemed to occur with similar frequency along the host. In relation to the cardinal orientation, the apparent preferential response for south and east directions was associated to the low sampling effort and lower water availability, which could occur because the north face is opposed to the water body.

This survey aimed at describing the interactions of floral visitors and Davilla kunthii A. St.-Hil. as well as characteristics of its reproductive biology in Itacoatiara, state of Amazonas, Brazil. Tests of the breeding system were performed. The guild of visitors was described according to richness, abundance, relative frequency and constancy. The breeding system tests indicated that D. kunthii is self-compatible. The pollination system was characterized as generalist, with 39 visitor species, from three different orders. Bees were the main group of pollinators, thus some behavioural aspects were described. Th e period of highest foraging activity was between 7 and 10 am. Some species presented agonistic and monopolistic behaviour. Given the behaviour and destructive potential, the Curculionidae seem to have a greater impact as seed predators than pollinators.

Size distributions in woody plant populations have been used to assess their regeneration status, assuming that size structures with reverse-J shapes represent stable populations. We present an empirical approach of this issue using five woody species from the Cerrado. Considering count data for all plants of these five species over a 12-year period, we analyzed size distribution by: a) plotting frequency distributions and their adjustment to the negative exponential curve and b) calculating the Gini coefficient. To look for a relationship between size structure and future trends, we considered the size structures from the first census year. We analyzed changes in number over time and performed a simple population viability analysis, which gives the mean population growth rate, its variance and the probability of extinction in a given time period. Frequency distributions and the Gini coefficient were not able to predict future trends in population numbers. We recommend that managers should not use measures of size structure as a basis for management decisions without applying more appropriate demographic studies.

Our aim was to verify the influence of a physical activities proposal in the quality of life and self image of incontinent women. This study was comparative and exploratory and was developed in 16 weeks. Thirty-seven women with and without urinary incontinence (IU) participated in the study. After the study, significant improvement in general health perception (p < 0.001), UI impact (p = 0.035), physical limitations (p = 0.015), personal relations, (p = 0.048), sleep and disposition (p = 0.012) and concerned with the gravity measurements (p = 0.011) was observed. Concerning self image, alterations in appearance were not observed; however, concerning body satisfaction, the women felt less satisfied with their bodies (p = 0.007). There was a reduction in the number of regions where they felt pain (p = 0.0003) and that they did not like (p = 0.0017). In conclusion, the Physical Education professionals using a systematized and integrated physical activities program can lead the women with IU to significant improvement in the perception of their quality of life and health concerning their self image with improvement of the IU symptoms and reduction of frequency and amount of urinary loss.
