DNA inoculation with a plasmid vector carrying the faeG adhesin gene of Escherichia coli K88ab induced immune responses in mice and pigs.

pCB01, an eukaryotic expression vector, was constructed by cloning faeG, the gene that encodes the fimbrial adhesin of Escherichia coli K88ab, in pcDNA3. Mice and swine were inoculated by the intramuscular route with different quantities of plasmid DNA to evaluate its capacity to induce an immune response. The immune response was monitored by ELISA and immunoblotting, using purified fimbriae and whole suspensions of fimbriated bacteria. Mice showed seroconversion 21 days after the inoculation of 8.9 microg and swine after the administration of 1100 microg of plasmid DNA. Seroconversions increased after successive reinoculations. Immunoblotting showed that sera collected 73 days after the first inoculation recognized exclusively a protein of 27 kDa present in purified fimbrial suspensions and in whole suspensions of E. coli K88ab. The immune response elicited by pCB01 was mainly due to IgG2a, while that elicited by a bacterin was due to IgG2b and IgG3. Antibodies were still detected 14 months after the initiation of the immunization.

[Normal neonatal cerebral ultrasonography in preterm infants - Is it possible to calm down the parents?] / Ultra-sonografia cerebral neonatal normal no prematuro - é possível tranqüilizar os pais?

OBJECTIVE: To verify the predictive values of neonatal cerebral ultrasonography for motor and cognitive development of very low birth weight preterm babies after twelve months correct age. METHODS: The population studied was a cohort of preterm babies with birth weight less than 1,500g, who had been admitted in the Neonatal Intensive Care Unit of Instituto Fernandes Figueira, and were followed to 12-30 months corrected age for prematurity. A cerebral ultrasonography was performed before discharge. The results were classified as normal and abnormal (parenchymal hemorrhage, porencephaly, periventricular leucomalacia, ventricular dilatation). The babies were followed in the Follow-up Clinic and between 12-30 months correct age they underwent a neurological assessment with observation of the acquisition of motor milestones and submitted to Bayley Scales of Development. RESULTS: We studied 83 babies. Cerebral ultrasonography was normal in 68 babies (81.9%) and abnormal in 15 (18.8%). With a mean age of 21 months, 63 children (75.9%) had normal motor development and 20 (24.0%) had motor abnormalities. The cognitive development was normal in 68 children (81.9%). The negative predictive value of the cerebral ultrasonography for motor development was 85.3%, and for cognitive development, 86.8%. The positive predictive value of the cerebral ultrasonography for motor development was 66.7% and for cognitive development, 42.9%. CONCLUSIONS: The negative predictive values were greater than the positive predictive values in both areas of development. The probability for children with normal neonatal ultrasonography to have normal motor and cognitive development is greater than 85%.

Human infection by Phagicola sp. (Trematoda, Heterophyidae) in the municipality of Registro, São Paulo State, Brazil.

In 1988, nine cases of human parasitism by Phagicola sp. were diagnosed in the municipality of Registro (São Paulo State, Brazil) by stool examinations, in patients who ate raw mullet (Mugil sp.). Six (66%) of the nine patients suffered from flatulence and four (44%) had diarrhoeal episodes; six (66%) showed slight eosinophilia. On the same occasion, 61 dogs and 11 cats from Registro were also submitted to stool examination. Only one dog (1.6%) showed Phagicola eggs in the stool. All patients were treated with a single dose of praziquantel (50 mg kg-1 body weight) and control stool tests performed on the 15th, 30th and 60th days post-treatment showed no trematode eggs.

Síndrome compressiva do túnel do carpo: aspectos clínicos e semiológicos; resultados do tratamento cirúrgico

Tratamento das pseudo-artroses infectadas com fixadores externos e cadeias de gentamicina - PMMA. / Infected pseudo-arthrosis treated with external pin fixation and gentamicin-PMMA chains

Um esquema terapeutico padronizado foi empregado em 14 pacientes portadores de pseudo-artrose infectada, tratados no Hospital da Policia Militar do Rio de Janeiro O metodo da enfase ao desbridamento amplo de todos os tecidos desvitalizados, a estabilizacao do foco de pseudo-artrose por meio de fixadores externos e a associacao de cadeias de perolas de gentamicina-PMMA colocadas nas cavidades resultantes do desbridamento. Os retalhos musculares e os enxertos cutaneos e osseos sao preconizados em tempo cirurgico futuro, quando debelada a infeccao.Os resultados foram considerados bons em 71,4% dos casos com base na cura da infeccao, consolidacao da fratura, boa cobertura cutanea, alem de recuperacao articular. Nenhum estudo comparativo com outras formas de tratamento foi realizado, porem, os autores enfatizam as vantagens dos fixadores externos que permitem uma boa estabilizacao sem material estranho ao foco fraturario facilitando os procedimentos futuros, alem de manter as articulacoes livres durante o periodo de tratamento. Tambem observam que, apos associarem as cadeias de perolas de gentamicina-PMMA, as cirurgias complementares foram realizadas mais precocemente, gracas a esterilizacao mais efetiva do foco de pseudo-artrose, diminuindo, em consequencia, o tempo de internacao e o custo hospitalar

Osteossintese de clavicula com pinos de Knowles. / Clavicle's osteosynthesis with Knowles' pins

Os autores apresentam 22 casos de fraturas de clavicula tratados cirurgicamente com fixacao intramedular utilizando pinos de Knowles, sendo 20 fraturas recentes e dois casos de pseudo-artrose sintomatica.A tecnica com pinos de Knowles e de facil execucao e permite uma fixacao rigida e estavel. Na opiniao dos autores, a grande vantagem do metodo esta no fato de nao necessitar de imobilizacao externa no pos-operatorio e evitar a migracao do fio de sintese, complicacao frequente nas tecnicas usuais de osteossintese intramedular com fios de Kirschner e Steinmamm
