SUMMARY Sapoviruses (SaVs) are responsible for acute gastroenteritis in humans, especially children and the elderly. In Brazil, data on SaVs infections are very limited, especially in Northern Brazil. Here, we investigated the occurrence of SaVs in samples from hospitalized children under ten years old that presented acute gastroenteritis. Positive samples were genotyped and phylogenetic analysis was performed using prototype strains sequences obtained from GenBank database. In total, 156 fecal samples were screened by RT-PCR for SaVs. A positivity rate of 3.8% (6/156) was found in children under three years of age. Four genotypes were detected: GI.I, GI.2 and GII.2?-GII.4?/GII.4, suggesting a possible inter-genotypes recombination. Most infections (83.3%) occurred between August and September. The positivity was similar to that found in other countries and genotyping demonstrated the presence of distinct genotypes. To our knowledge, this is the first study reporting the circulation of SaVs in Manaus, state of Amazonas, Amazon region, Brazil.

Este artigo enfoca a noção de silêncio sob a ótica da psicanálise. Diversas são as referências que nos levam à constatação de que há um duplo estatuto do silêncio - o atendimento clínico, as formulações da psicanálise lacaniana, a literatura de Clarice Lispector. Buscamos conceituar essa duplicidade, articulando um silêncio à noção de vazio e, outro, à noção de falta. Para tal diferenciação, usamos como recursos as noções matemáticas de zero e -1 (subtração de 1)

This article focus on the notion of silence under the perspective of the psychoanalysis. Several are the references that lead us to verify the double statute of the silence - the clinical "procedure", the "formulations" of the lacanian psychoanalysis, the literature of Clarice Lispector, the linguistic theory of Eni Orlandi. The aim is to judge this duplicity, linking one silence to the notion of emptiness and the other one to the notion of absence. For such differentiation, is used the resource of the mathematical notion of zero and -1 (minus one)

Cet article traite de la notion du silence dans la perspective de la psychanalyse. Il y a des divers références qui constatent l'existence d'un double statut du silence - la clinique, les formulations de la psychanalyse lacanienne, la littérature de Clarice Lispector. On cherche à expliquer le concept de cette duplicité ajoutant un silence à la notion du vide et un autre à la notion du manque. Pour cette différentiation, on utilise les notions mathématiques de zéro et de -1 (soustraction de 1)
