Este trabalho relata um caso de tentativa de infanticídio por um macho residente e dominante de um grupo de Alouatta caraya (Humboldt, 1812) em um infante extra-grupo, em ilha do rio Paraná, Paraná, Brasil. O encontro do par fêmea-infante com o macho residente foi propiciado pela interferência humana. Devido às circunstâncias em que ocorreu o fato e a posição hierárquica do agressor, a hipótese de patologia social pareceu plausível na explicação do comportamento.<br>This work reports on an infanticide attempt by a dominant resident male in a group of Alouatta caraya (Humboldt, 1812) on an extra-group infant in an Island in the Paraná river, Paraná, Brazil. The encounter of an infant-female pair with a resident male was brought about by human interference. Give the circumstances in which the event ocurred and the hierarchical position of the agressor, the social pathology hypothesis seems the most plausible explanation for such behavior

Lung abscess

A lung abscess is a thick-walled cavity that contains purulent material [1-2]. It is a rare condition in children. It arises as a complication of a poorly controlled pneumonia, and has an estimated incidence of 0.7 per 100,000 hospital admissions/year. A lung abscess can be defined to be \u201cprimary\u201d if it occurs in a previously healthy child or \u201csecondary\u201d if underlying conditions predispose to the onset of the abscess [1-8]. It can be \u201cacute\u201d or \u201cchronic\u201d if it has been present for &gt;6 weeks [1, 9]
