Necrotizing fasciitis in a newborn infant: a case report

We report the case of a one-day-old newborn infant, female, birth weight 1900 g, gestational age 36 weeks presenting with necrotizing fasciitis caused by E. coli and Morganella morganii. The newborn was allowed to fall into the toilet bowl during a domestic delivery. The initial lesion was observed at 24 hours of life on the left leg at the site of the venipuncture for the administration of hypertonic glucose solution. Despite early treatment, a rapid progression occurred resulting in a fatal outcome. We call attention to the risk presented by this serious complication in newborns with a contaminated delivery, and highlight the site of the lesion and causal agents.

Contribuição a história natural do «Pararu» Scardafella squammata squammata(Lesson) (1)

The main wild doves of the region of Piracicaba (State of S. Paulo, Brazil) are Columba cayennensis sylvestris Vieillot, Oreopeleia montana montana (L.), Leptotila verreauxi decipiens Salvadori, Columbigallina talpacoti talpacoti. (Temminck) and Scardafella squammata squammata (Lesson). The last one is well known for the beauty of the coloration of its feathers and for the characteristic sounds produced when flying up. Of common occurrence around the local farms, that species can easily be recognized not only for the mentioned peculiarities as for the voice of the adults, which was translated into the Brazilian onomatopoeia by the expression "fogo-apagou". S. squammata's biology being not well known, the Author presents some notes on its nidification, behaviour of both sexes and of the young birds. The data were gotten in nature and with specimens kept in captivity, where the reproduction took place. In such a situation, the male dove used thin and small wooden shavings to build the nest, an artificial material unknown by him when in nature. This fact may be considered as another proof of the plasticity of the instinctive conduct of birds, not so marked as the one given by SCHIRCH (1931) concerning Synallaxis sp. (Furnariidae), which made use of wire pieces and also barbed wires in confectioning the nest. The copulation was sometimes verified, being preceded by the phenomena well known in other Columbidae species. The nest had its building ready just on the day in which the first egg was laid. As it generally happens amongst doves, the nest was not carefully made - a simple and shallow bowl (diameter = 10 cm), where two entirely white eggs were put.. .. ..(22,5-24,5 x 18,0-19,0 mm). The eclosion took place 14 days after the laying of the last egg. As soon as the young doves (at least the male one) can feed by themselves, they try to produce the characteristic species sounds. "Pararu", a common name oly applied to another species - Claravis godefrida (Temminck) - is reported, which is preferably used by people in this region to call the studied dove. No differences between the coloration of the fathers of the two sexes were observed. The female dove seemed to be a little thinner than the male. In addition, the slight differences between the sounds produced by the male and female are pointed out.

Mancha de Septoria da alface: isolamento, inoculação e avaliação de cultivares em condições de campo e casa de vegetação

Este trabalho teve como objetivo estabelecer metodologias adequadas para o isolamento e inoculação de Septoria lactucae e avaliação de nove cultivares de alface (Lactuca sativa), Vitória-de-Santo-Antão, Uberlândia 10.000, Maioba, Elba, Aurélia, Black Seeded Simpson, Grand Rapids, Salad Bowl-Mimosa e Babá de Verão, quanto aos níveis de resistência à septoriose, em condições de casa de vegetação e campo. Os melhores resultados obtidos foram: a) para isolamento: transferência dos cirros de conídios diretamente para o meio de BDA com os antibióticos estreptomicina, cloranfenicol, ampicilina e rifampicilina; b) para inoculação: aspersão das plantas no estádio de seis a oito folhas com a suspensão de inóculo na concentração de 1 x 10(4)conídios/ml, e manutenção em câmara úmida por 48 h. Houve diferenças significativas entre as cultivares testadas em casa de vegetação e em campo. Tanto em casa de vegetação quanto em teste de campo as cultivares Maioba e Vitória de Santo Antão foram avaliadas como a mais susceptível e a mais resistente, respectivamente. Diante desses resultados, a metodologia de casa de vegetação pode ser considerada como altamente promissora para a avaliação rápida de grande número de variedades ou materiais genéticos, nos trabalhos de melhoramento de alface para a resistência à S. lactucae.
