    Unfortunately, no any vaccine against leishmaniasis has been developed for human use. Therefore, a vaccine based on total Leishmania antigens could be a good and economic approach; and there are different methodologies to obtain these antigens. However, it is unknown whether the method to obtain the antigens affects the integrity and immune response caused by them. OBJECTIVES: to compare the protein profile and immune response generated by total L. amazonensis antigens (TLA) produced by different methods, as well as to analyse the immune response and protection by a first-generation vaccine formulated with sonicated TLA (sTLA) and polyinosinic:polycytidylic acid [Poly (I:C)]. METHODS: TLA were obtained by four different methodologies and their integrity and immune response were evaluated. Finally, sTLA was formulated with Poly (I:C) and their protective immune response was measured. FINDINGS: sTLA presented a conserved protein profile and induced a strong immune response. In addition, Poly (I:C) improved the immune response generated by sTLA. Finally, sTLA + Poly (I:C) formulation provided partial protection against L. amazonensis infection. MAIN CONCLUSIONS: The protein profile and immune response depend on the methodology used to obtain the antigens. Also, the formulation sTLA + Poly (I:C) provides partial protection against cutaneous leishmaniasis in mice.Fil: Germano, Maria Jose. Consejo Nacional de Investigaciones Científicas y Técnicas.

    We report the case of a 27 year old man who presented to the emergency room of a hospital with headache, vomiting and an episode of loss of conciousness. A cranial CT scan was normal and the patient discharged. Ten hours later he came to the emergency room of our hospital with the same complaints. A technically difficult cisternal puncture in an anxious patient who moved during the needle introduction was done. The CSF sample showed 1600 intact red blood cells without other alterations. His headache worsened and after 6 hours he became drowsy, numb and exhibited decerebration signs. A new CT scan showed diffuse subarachnoid and intraventricular blood. An emergency angiogram demonstrated laceration of a left posterior-inferior cerebellar artery in its retrobulbar loop with a pseudoaneurysm. He was succesfully treated by surgical clipping without injury. Sixteen days later he was discharged with a normal neurological exam.<br>Relatamos o caso de um homem de 27 anos que procurou o pronto atendimento de um hospital com cefaléia intensa, vômitos e um episódio de perda de consciência. Uma tomografia de crânio foi normal e o paciente foi dispensado. Dez horas após, o paciente procurou o setor de emergência do nosso hospital com as mesmas queixas. Uma punção suboccipital tecnicamente dificultada pela ansiedade do paciente que se movimentou durante a coleta foi realizada evidenciando amostra de LCR levemente hemorrágico. A análise do LCR mostrou presença de 1600 hemácias íntegras sem aumento de leucócitos nem alterações bioquímicas. Houve piora acentuada da cefaléia e após 6 horas apresentou sonolência, torpor e sinais de descerebração. Nova tomografia mostrou sangue no espaço subaracnóideo e nos ventrículos. Uma angiografia realizada de emergência demonstrou laceração da artéria cerebelar póstero-inferior esquerda com a formação de um pseudoaneurisma. O paciente foi de imediato operado tendo sido realizada a clipagem do pseudoaneurisma com sucesso. Dezesseis dias após o paciente teve alta com exame neurológico normal

    OBJETIVO: Determinar prevalência de crianças portadoras de respiração oral inscritas no Projeto Santo Amaro/ ESEF/ UPE e verificar as principais alterações faciais e comportamentais associadas. FORMA DE ESTUDO: Estudo transversal. MATERIAL E MÉTODO: Amostra de 150 crianças de 8 a 10 anos. Dados coletados mediante aplicação de questionário e exames clínicos. Para o diagnóstico da respiração foram feitos dois testes. Teste 1, observado no espelho, vapor decorrente da respiração, e teste 2, a permanência de água na boca com os lábios em contato pelo tempo de 3 minutos. RESULTADOS: Prevalência de respiração oral foi de 53,3%. Não se comprovou diferença significante entre gênero, faixa etária, tipo de respiração. As alterações faciais da respiração oral foram: selamento labial inadequado (58,8% x 5,7%), olhos caídos (40,0% x 1,4%), palato ogival (38,8% x 2,9%), mordida aberta anterior (60,0% x 30,0%), lábios hipotônicos (23,8% x 0,0%) e olheiras (97,5% x 77,1%). CONCLUSÃO: Prevalência de respiração oral elevada sem diferença estatística entre os gêneros, faixa etária e tipo de respiração oral. Não houve associação entre características comportamentais e o tipo de respiração. Houve diferença significante entre as características físicas e o padrão de respiração.<br>AIM: To determine the prevalence of mouth breathing children at the santo amaro project/ esef/ upe, and study their main facial and behavior alterations. STUDY DESIGN: transversal study. MATERIAL AND METHODS: there were 150 children in the sample, with ages ranging from 8 to 10 years. Data was collected by means of a questionnaire and clinical examinations. As for their breathing assessment, two tests were carried out: test 1- breath steam against a mirror; and test 2 -water remains in the mouth with lips closed for 3 minutes. RESULTS: mouth breathing prevalence was of 53.3%. There was no significant difference between gender, age and type of breathing. Facial alterations were:incomplete lip closure ( 58.8% X 5,7%), fallen eyes ( 40.0% X 1.4%), High palate ( 38.8% X 2.9%), Anterior open bite ( 60.0% Versus 30.0%), Hypotonic lips ( 3.8% X 0.0%), Circles under the eyes (97.5% Versus 77.1%). CONCLUSION: high mouth breathing prevalence without significant statistical difference between genders,age and type of mouth breathing. There was no association between behavior characteristics and type of breathing. There were significant differences between physical traits and breathing pattern
