Fluxograma diferenciado no pré-natal e a garantia da assiduidade das gestantes do início ao fim

O estudo consiste em pesquisa aplicada cuja motivação foi a inassinuidade das gestantes nas consultas seguintes do pré-natal, fundamentando implantação de novo fluxograma de marcação das consultas de retorno do mesmo, garantindo uma assistência pré-natal eficiente. Pré-natal é acompanhamento médico que mantém o bem estar materno-fetal. No Brasil, as gestantes aderem facilmente ao programa, no entanto o problema é a falta de frequência em todo o pré-natal, já que a marcação do retorno é feito na recepção da UBS mediante a retirada de ficha disponível em número limitado. Assim, com o intuito de solucionar a dificuldade de marcação de consultas de retorno no pré-natal resolvemos elaborar novo fluxograma desse processo de atendimento, destinado as gestantes da UBS de Jardim Colorado da área 29. Realizou-se reunião da equipe de saúde para estimar o número de gestantes, agenda manual de registros de gestantes, busca ativa de pacientes que ainda não haviam iniciado o pré-natal. Feito isso, elaboramos o fluxograma, que facilitará a marcação das consultas de retorno do pré-natal diminuindo a inassinuidade das gestantes durante todo o pré-natal, aumentando a adesão de gestantes que fazem o acompanhamento pré-natal na UBS de Jardim Colorado área 29, contribuindo para a melhoria da assistência pré-natal.

Desenvolvimento morfológico dos ovários em fetos eqüinos sem raça definida

O objetivo deste trabalho foi caracterizar histologicamente o desenvolvimento ovariano pré-natal em fetos eqüinos sem raça definida (SRD) nos trópicos, ressaltando surgimento e quantificação de ovogônias e folículos. Foram obtidos 131 fetos em frigorífico, os quais foram mensurados quanto ao comprimento (cm) equivalente à distância cefalococcígea (CR), seguido de corte das gônadas e fixação das amostras em Bouin por 24 horas. As idades foram estimadas por regressão. Foram preparados cortes histológicos ovarianos de 7µm de espessura, os quais foram corados com hematoxilina-eosina. O surgimento de ovogônias, folículos primordiais, em crescimento e antrais foi verificado, respectivamente, em fetos com CR entre 4,1 e 6,5cm (40 a 49 dias de gestação (DG)); 9,1 e 12,0cm (60 a 69 DG); 23,1 e 29,0cm (116 a 135 DG) e 50,1 e 65,0cm (201 a 245 DG). A quantidade máxima de ovogônias, folículos primordiais, em crescimento e antrais foi observada em fetos com CR entre, 4,1 e 6,0cm (40 a 49 DG); 16,1 e 23,0cm (90 a 115 DG); 29,1 e 36,0cm (136 a 155 DG) e 50,1 e 97,0cm (201 a 320 DG), respectivamente. Os resultados sugerem que o desenvolvimento morfológico dos ovários fetais de eqüinos SRD nos trópicos é mais precoce que o observado nos relatos de literatura referentes a estudos de eqüinos de diversas raças em regiões temperadas.

Homocysteine and cysteine concentrations are modified by recent exposure to environmental air pollution in Sao Paulo, Brazil

Millions of people worldwide are affected by anthropogenic air pollution derived from the combustion of fossil fuels. In this work, we tested the effects of fetal, lactation and post-weaning ambient air pollution exposure on total homocysteine (tHcy) concentrations and on a downstream pathway element, the plasma cysteine (Cys) concentration. Two similar exposure chambers (polluted and filtered chamber) were located near an area with heavy traffic in Sao Paulo, Brazil, and male Swiss mice were housed there from the pre-natal period until 3 months of age. Groups during fetal, lactation and adult periods of exposure were apportioned, and tHcy and Cys plasma concentrations were assessed when the animals were 3 months old. In our study, both the tHcy and Cys concentrations were decreased in groups that spent their final stage of life in polluted chambers, suggesting recent alterations in tHcy and Cys concentrations due to air pollution exposure. The possible relationship of these data with cardiovascular dysfunction is still a matter of controversy in animals; nevertheless, epigenetic mechanisms emerge as a possible issue to consider in the investigation of the link between air pollution and Hcy measurement.

Permanent vascular access in patients with end-stage renal disease, Brazil

OBJECTIVE: To assess factors associated with the establishment of permanent vascular access for patients with end-stage renal disease. METHODS: Cross-sectional study conducted in a nationally representative sample of Brazilian end-stage renal disease patients in dialysis and transplant centers during 2007. The sample comprised only patients who received hemodialysis as a primary therapy modality and reported the type of vascular access for their primary hemodialysis treatment (N=2,276). Data were from the TRS Project - "Economic and Epidemiologic Evaluation of Modalities of Renal Replacement Therapy in Brazil". Multiple logistic regression analysis was used to assess factors associated with the establishment of permanent vascular access in these patients. RESULTS: About 30% of the patients studied had an arteriovenous vascular access. The following factors were associated with a lower likelihood of having an arteriovenous vascular access as a primary type of access: time of hemodialysis start since the diagnosis of chronic renal failure < 1 year; shorter dialysis therapy; having no private health insurance; living in the central-western, northeastern and southeastern regions of Brazil; and living in the northern region plus having no private health insurance. In the final model there was found a positive association between the outcome and pre-dialysis care and no were association with socioeconomic and comorbidity variables. CONCLUSIONS: The study results showed that the focus should on pre-dialysis care to increase the establishment of an arteriovenous vascular access before starting hemodialysis in Brazil.

Tecnologias Multimédia no Apoio ao Ensino da Assistência Pré-Hospitalar

Vivemos num mundo em constante mudança, onde a evolução tecnológica está cada vez mais presente no nosso quotidiano e as suas influências são inúmeras nas nossas vidas. Por outro lado, a vida humana é algo extremamente valioso e único pelo que a sociedade, também nessa área, tem procurado evoluir e dotar-se de novos meios e mecanismos de atuação, que possibilitem um socorro rápido e adequado em situações que possam em algum momento pôr em perigo a vida do ser humano. Pretendemos com o presente estudo, correlacionar estas duas vertentes, a do socorro á vítima para apoio á vida humana e a tecnologia no sentido de contribuir para uma formação mais distribuída mas ao mesmo tempo capaz de transmitir conhecimentos necessários á formação dos que socorrem. Para o efeito, planeamos o desenvolvimento de um Objeto de Aprendizagem (OA) denominado CiTAT (Curso Interativo de Tripulante de Ambulância de Transporte) que tem como objetivo acrescentar valor a todos os que são obrigados a frequentar o curso em regime presencial de Tripulante de Ambulância de Transporte (TAT). Após uma fase de análise do estado da arte relacionada com este tipo de formação, e após termos percebido como funciona e que tipos de recursos utilizam, analisámos temas relacionados com este tipo de formação como o “Sistema Integrado de Emergência Médica” o “Exame á Vítima”, o “Suporte Básico de Vida” e as “Emergências de Trauma”. Percebemos que a mudança de paradigma de formação das pessoas passou a ter novas formas de distribuir conhecimento em formato digital e que proporciona aos formandos um ensino distribuído em formatos de e-learning ou de b-learning. Os Objetos de Aprendizagem (OA) parecem assumir um relevo especial no ensino da área da saúde, abordando áreas temáticas e proporcionando aos seus utilizadores mecanismos de autoavaliação após a visualização dos conteúdos pedagógicos. Após o desenho do modelo concetual do CiTAT, avançamos para a produção de recursos necessários para a sua integração no OA. Após uma fase de testes e ajustes, avançamos para a sua avaliação final por parte dos utilizadores e preparamos um questionário para aferir o potencial de utilização deste tipo de soluções no ensino de TAT, atendendo ao facto de ser uma formação obrigatória e cuja recertificação é feita de três em três anos. O passo final foi a sua distribuição ao nível global, sendo o CiTAT catalogado com metadados e colocado no repositório MERLOT.

Cortisol e testosterona no plasma da grávida e no líquido amniótico: variação com o relaxamento e correlação com o rácio digital 2D:4D no recém-nascido

RESUMO: Conclusão - Este estudo sugere que mulheres grávidas beneficiam da prática rotineira de 30 min de relaxamento perante a eminência de um acontecimento indutor de stress. O benefício será tanto psicológico como fisiológico e será mais marcado de manhã do que de tarde. As mulheres com maior tendência ansiosa, tipicamente as mais jovens e com menos idade gestacional, serão as que mais beneficiam. Entre os tipos de intervenção experimentados, todos eles não dispendiosos, a audição de música foi globalmente o mais eficaz para o propósito pretendido. A variação do cortisol e a variação da testosterona estão altamente correlacionadas, e este efeito poderá ser explorado em futuras intervenções relaxantes. Programas curtos de relaxamento poderão conduzir a benefícios para o bem-estar psicológico e para a saúde da grávida, com benefícios adicionais no desfecho da gravidez. O rácio digital 2D:4D do recém-nascido apresenta características sexualmente dimórficas, sendo mais baixo em rapazes que em raparigas, confirmando a influência dos androgénios pré-natais, mas há grande sobreposição entre os sexos pelo que, isoladamente, não pode ser utilizado como marcador de risco. No entanto, se associado a outros marcadores biológicos, como o peso ao nascer e a circunferência cerebral, entre outros, poderá ser um parâmetro a valorizar desde cedo, possivelmente no acompanhamento pediátrico. Nas raparigas, o RD da mãe e a testosterona no LA explicam uma proporção significativa do seu 2D:4D. Em ambos os sexos, o rácio 2D:4D aumenta após o nascimento e o dimorfismo sexual observado com base em amostras de crianças com mais de dois anos de idade, é afectado pela testosterona pós-natal, especialmente no que se refere à mão direita.----------ABSTRACT: Conclusions - This study suggests that pregnant women would benefit from the routine practice of 30min relaxation when at the imminence of a stressful event. The benefit would be both psychological and physiological and would be more pronounced in the morning than in the afternoon. Women tending to be more anxious, typically younger and at a lower gestational age, are the ones that benefit the most. Among the interventions investigated, all being non-expensive and easy to implement, listening to relaxing music was globally the most efficient for the benefit intended. The variation of cortisol and the variation of testosterone are significantly correlated, an association that might be used in future relaxation interventions. It is feasible to conceive short relaxation programs aimed at benefiting psychological well-being and health in pregnancy, with additional benefits for pregnancy outcome. The digital ratio 2D:4D is sexually dimorphic, being lower in males than in females, confirming the influence of pre-natal androgens. There is however large overlap between sexes, rendering the 2D:4D a risk marker not to be used in isolation but rather in association with other markers, like for instance the weight at birth and the head circumference, wherein it may be a relevant parameter for pediatric follow-up. In newborn females, a significant amount of variability in 2D:4D is accounted for by their mother’s digital ratio and AF testosterone. In both sexes, the 2D:4D ratio increases following birth and sexual dimorphism,as assessed from samples of subjects with more than 2 years of age, is affected by post-natal testosterone, especially in what concerns the right hand.

Fetal tachyarrhythmia with 1:1 atrioventricular conduction. Adenosine infusion in the umbilical vein as a diagnostic test

This is the report of a case of fetal tachyarrhythmia with 1:1 atrioventricular conduction detected by pre-natal echocardiography in a fetus at 25-weeks gestation. Adenosine infusion via cordocentesis was performed as a diagnostic test to differentiate between atrioventricular nodal reentrant supraventricular tachyarrhythmia and atrial flutter. After infusion, transient 2:1 atrioventricular dissociation was obtained and the diagnosis of atrial flutter was made. Transplacental therapy with digoxin and amiodarone was then successfully used.

Le conseil génétique: aspects théoriques et pratique en prénatal [Genetic counselling: theoretical aspects and prenatal practice]

Le conseil génétique doit fournir aux individus une information médicale précise et un soutien psychologique. L'importance des principes d'autonomie et de confidentialité, dogmes du conseil génétique, est renforcée par la nouvelle loi suisse (LAGH). Dans certains pays, une grande partie du conseil génétique est assurée par des conseillers en génétique non médecins ayant une formation postgraduée spécifique. Le conseil génétique joue un rôle grandissant dans différents domaines de la médecine. En particulier, il est indispensable dans le contexte du prénatal où les couples reçoivent des informations complexes et doivent bénéficier d’un soutien pour prendre une décision. Genetic counselling provides families with accurate medical information and psychological support. Respect and concern for the emotional well-being should be taken into account while discussing genetics aspects and recurrence risks. The importance of autonomy and confidentiality, central to genetic counselling, is reinforced by the new Swiss law (LAGH). In many countries, most of the genetic counselling is provided by genetic counsellors who have a specialised post-graduate training. Genetic counselling plays an increasing role in different medical specialities. In particular, it is essential in the context of prenatal and pre-conceptual care, where couples are confronted to complex information and should have access to appropriate support during the decision-making process

Reversible acquired epileptic frontal syndrome and CSWS suppression in a child with congenital hemiparesis treated by hemispherotomy.

A boy with a right congenital hemiparesis due to a left pre-natal middle cerebral artery infarct developed focal epilepsy at 33 months and then an insidious and subsequently more rapid, massive cognitive and behavioural regression with a frontal syndrome between the ages of 4 and 5 years with continuous spike-waves during sleep (CSWS) on the EEG. Both the epilepsy and the CSWS were immediately suppressed by hemispherotomy at the age of 5 years and 4 months. A behavioural-cognitive follow-up prior to hemispherotomy, an per-operative EEG and corticography and serial post-operative neuropsychological assessments were performed until the age of 11 years. The spread of the epileptic activity to the "healthy" frontal region was the cause of the reversible frontal syndrome. A later gradual long-term but incomplete cognitive recovery, with moderate mental disability was documented. This outcome is probably explained by another facet of the epilepsy, namely the structural effects of prolonged epileptic discharges in rapidly developing cerebral networks which are, at the same time undergoing the reorganization imposed by a unilateral early hemispheric lesion. Group studies on the outcome of children before and after hemispherectomy using only single IQ measures, pre- and post-operatively, may miss particular epileptic cognitive dysfunctions as they are likely to be different from case to case. Such detailed and rarely available complementary clinical and EEG data obtained in a single case at different time periods in relation to the epilepsy, including per-operative electrophysiological findings, may help to understand the different cognitive deficits and recovery profiles and the limits of full cognitive recovery.

Reversible acquired epileptic frontal syndrome and CSWS suppression in a child with congenital hemiparesis treated by hemispherotomy

Rapport de synthèse : Cette thèse a étudié en détail le cas d'un enfant souffrant d'une hémiplégie congénitale sur un infarctus prénatal étendu qui a développé une forme particulière d'épilepsie, le syndrome des pointes ondes continues du sommeil (POCS), associé à une régression mentale massive. Les caractéristiques de cette détérioration pointaient vers un dysfonctionnement de type frontal. Une chirurgie de l'épilepsie (hémisphérotomie) a, non seulement, permis la guérison de l'épilepsie mais une récupération rapide sur le plan comportemental et cognitif, suivie d'une reprise plus lente du développement, avec finalement à l'âge de 11 ans un niveau de déficience intellectuelle modérée. L'intérêt de cette étude réside dans le fait que l'enfant a pu être suivi prospectivement entre l'âge de 4.5 ans et 11 ans par des enregistrements électro-encéphalographiques (EEG) ainsi que des tests neuropsychologiques et des questionnaires de comportements sériés, permettant de comparer les périodes pré-, péri- et postopératoires, ce qui est rarement réalisable. Un enregistrement EEG de surface a même pu être effectué durant l'opération sur l'hémisphère non lésé, permettant de documenter l'arrêt des décharges épileptiformes généralisées dès la fin de l'intervention. L'hypothèse que nous avons- souhaité démontrer est que la régression comportementale et cognitive présentée par l'enfant après une période de développement précoce presque normale (retard de langage) était de nature épileptique : nous l'expliquons par la propagation de l'activité électrique anormale à partir de la lésion de l'hémisphère gauche vers les régions préservées, en particulier frontales bilatérales. L'hémisphérotomie a permis une récupération rapide en déconnectant l'hémisphère gauche lésé et épileptogène de l'hémisphère sain, qui a ainsi pu reprendre les fonctions cognitives les plus importantes. Les progrès plus lents par la suite et l'absence de rattrapage au delà d'un niveau de déficience mentale modérée sont plus difficiles à expliquer: on postule ici un effet de l'épilepsie sur le développement de réseaux neuronaux de l'hémisphère initialement non lésé, réseaux qui sont à la fois à un stade précoce de leur maturation et en cours de réorganisation suite à la lésion prénatale. La littérature sur les déficits cognitifs avant et après hemisphérotomie s'est surtout préoccupée du langage et de sa récupération possible. À notre connaissance, notre étude est la première à documenter la réversibilité d'une détérioration mentale avec les caractéristiques d'un syndrome frontal après hémisphérotomie. La chirurgie de l'épilepsie a offert ici une occasion unique de documenter le rôle de l'activité épileptique dans la régression cognitive puisqu'en interrompant brusquement la propagation de l'activité électrique anormale, on a pu comparer la dynamique du développement avant et après l'intervention. La mise en relation des multiples examens cliniques et EEG pratiqués chez un seul enfant sur plusieurs années a permis d'obtenir des informations importantes dans la compréhension des troubles cognitifs et du comportement associés aux épilepsies focales réfractaires.
