Epidemiological analysis of polytrauma patients with kidney injuries in a university hospital

Objective: To analyze the characteristics of trauma patients with renal lesions treated at a university hospital in Curitiba. Methods: We conducted a retrospective, cross-sectional study guided by review of medical records of trauma victims who underwent surgical treatment. The variables analyzed were age, gender, mechanism of injury, degree of kidney damage, conduct individualized according to the degree of renal injury, associated injuries, complications and deaths. We classified lesions according to the American Association of Trauma Surgery (TSAA). Results: We analyzed 794 records and found renal lesions in 33 patients, with mean age 29.8 years, most (87.8%) being male. Penetrating trauma accounted for 84.8% of cases. The most common renal injuries were grade II (33.3%), followed by grade I (18.1%), III, IV and V. Nephrectomy treated 45.4% of injuries, 73.3% being total nephrectomy, and 45.4% by nephrorraphy. In 9% treatment was non-surgical. Only 12.1% of patients had isolated renal lesions. Complications ensued in 15.1% and mortality was 6.06%. Conclusion: The surgical approach was preferred due to penetrating trauma mechanism. We achieved low rates of complications and deaths, and neither case could be directly related to kidney damage, and there were patients with multiple lesions. In this sample, we could not observe a direct relationship between kidney damage and complications, deaths or the type of conduct employed.

Effect of Carapa guianensis Aublet (Andiroba) and Orbignya phalerata (Babassu) in colonic healing in rats

Objective: to evaluate the healing effect of the babassu aqueous extract and andiroba oil on open wounds in the cecum of rats. Methods: fifty-four Wistar rats were divided into three groups of 18: 1) babassu group with application of aqueous extract of babassu; 2) andiroba group with application of the oil; and 3) control group, with application of saline solution. All procedures were done by gavage. Each group was divided into three subgroups of six animals according to the observation period of 7, 14 or 21 days. From each animal was removed caecum fragment of 1.5cm² diameter. The areas of the lesions were analyzed macroscopically and resected specimens by light microscopy using hematoxylin-eosin and Masson's trichrome. Results: abscess and infection were observed in two aroeira group animals, and in one only hematoma. In relationship to adhesions degree, babassu group had higher incidence of grade II while in the control and aroeira groups predominated adhesions grade I. On microscopic examination on day 7 fibroblast proliferation was greater in aroeira and lower in babassu group (p=0.028). On the 14th day polymorphonuclear were less pronounced in babassu (p=0.007). As for the resistance test of air insufflation, it was observed that in all andiroba group in all tested days showed be higher. As for collagen, on the 7th day it was present in 100% of animals of aroeira group. On the 14th day was more pronounced in the control group and at day 21 similar results were found in the control and aroeira groups. Conclusion: animals in babassu and andiroba groups showed better cecum healing compared to the control group.

Análise Comparativa de Testes Diagnósticos para Diabete Gestacional

Objetivos: avaliar os resultados maternos e perinatais de pacientes submetidas à curva glicêmica com 100 g de glicose, de acordo com três diferentes critérios diagnósticos. Métodos: realizou-se estudo do tipo corte transversal, incluindo 210 pacientes assistidas no Instituto Materno-Infantil de Pernambuco (IMIP), submetidas durante a gravidez ao teste oral de tolerância à glicose 100 g (TOTG), com gestação única, sem história de diabete ou intolerância aos carboidratos prévia à gestação e cujo parto foi assistido no IMIP. Estas foram classificadas nos grupos: controles, pacientes com hiperglicemia leve, diabete gestacional (DG) de acordo com os critérios de Bertini, de Carpenter e Coustan e do "National Diabetes Data Group" (NDDG). Analisaram-se esses grupos, buscando-se associação entre a classificação das pacientes nos grupos e a presença de pré-eclâmpsia, recém-nascidos grandes para a idade gestacional (GIG) e freqüência de cesarianas e natimortos, comparando-se ainda as médias de peso ao nascer. Resultados: a freqüência de DG de acordo com os critérios de Bertini, de Carpenter e Coustan e do NDDG foi de 48,1, 18,1, e 9%, respectivamente, ao passo que a freqüência de hiperglicemia leve foi de 10,5%. A idade das pacientes aumentou progressivamente de acordo com o maior grau de intolerância aos carboidratos. Os grupos não diferiram quanto à freqüência de GIG, cesarianas, natimortos e médias de peso ao nascer. Verificou-se aumento significativo da incidência de pré-eclâmpsia em pacientes com hiperglicemia e DG por Carpenter e Coustan, mas não nos outros grupos. Conclusões: a prevalência de diabete gestacional encontrada variou entre 9 e 48%, de acordo com os diversos critérios, mas não se observaram diferenças significativas nos resultados maternos e perinatais entre os grupos. Critérios muito rígidos de diagnóstico podem levar a diagnóstico excessivo, sem melhora subseqüente do prognóstico perinatal.

Avaliação de microcalcificações mamárias de acordo com as classificações do Breast Imaging Reporting and Data System (BI-RADS TM) e de Le Gal

OBJETIVO: avaliar a acurácia da mamografia para o diagnóstico de microcalcificações mamárias suspeitas, com as classificações do Breast Imaging Reporting and Data System (BI-RADS TM) e Le Gal em comparação com o resultado histopatológico utilizado como padrão-ouro. MÉTODOS: foram selecionados dos arquivos dos blocos cirúrgicos, 130 casos operados com mamografias contendo somente microcalcificações mamárias, inicialmente classificadas como suspeitas sem lesões detectáveis ao exame clínico. Estas foram reclassificadas por dois examinadores, utilizando as classificações de Le Gal e BI-RADS TM, obtendo-se diagnóstico de consenso. As biópsias foram revistas por dois patologistas e foi obtido diagnóstico de consenso. A leitura das mamografias e a revisão das lâminas foram feitas em duplo-cego. As análises estatísticas utilizadas neste estudo foram o teste do chi2, o modelo Fleiss quadrático para VPP e o programa Epi-Info 6.0. RESULTADOS: a correlação entre a análise histopatológica e mamográfica, usando BI-RADS TM e Le Gal, mostrou a mesma sensibilidade de 96,4%, especificidade de 55,9 e 30,3%, valor preditivo positivo (VPP) de 37,5% e 27,5% e acurácia de 64,6 e 44,6%, respectivamente. Quando discriminamos por categorias de BI-RADS TM, obtivemos VPPs: categoria 2, 0%; categoria 3, 1,8%; categoria 4, 31,6% e categoria 5, 60%. Os VPPs pela classificação de Le Gal foram: categoria 2, 3,1%; categoria 3, 18,1 %; categoria 4, 26,4%; categoria 5, 66,7% e não classificável, 5,2%. CONCLUSÕES: observou-se uma maior precisão com a classificação de BI-RADS TM, porém não se conseguiu reduzir a ambigüidade na avaliação das microcalcificações mamárias.

Salivary and serum cortisol levels, salivary alpha-amylase and unstimulated whole saliva flow rate in pregnant and non-pregnant

PURPOSE: To compare salivary and serum cortisol levels, salivary alpha-amylase (sAA), and unstimulated whole saliva (UWS) flow rate in pregnant and non-pregnant women. METHOD: A longitudinal study was conducted at a health promotion center of a university hospital. Nine pregnant and 12 non-pregnant women participated in the study. Serum and UWS were collected and analyzed every trimester and twice a month during the menstrual cycle. The salivary and serum cortisol levels were determined by chemiluminescence assay and the sAA was processed in an automated biochemistry analyzer. RESULTS: Significant differences between the pregnant and non-pregnant groups were found in median [interquartile range] levels of serum cortisol (23.8 µL/dL [19.4-29.4] versus 12.3 [9.6-16.8], p<0.001) and sAA (56.7 U/L [30.9-82.2] versus 31.8 [18.1-53.2], p<0.001). Differences in salivary and serum cortisol (µL/dL) and sAA levels in the follicular versus luteal phase were observed (p<0.001). Median UWS flow rates were similar in pregnant (0.26 [0.15-0.30] mL/min) and non-pregnant subjects (0.23 [0.20-0.32] mL/min). Significant correlations were found between salivary and serum cortisol (p=0.02) and between salivary cortisol and sAA (p=0.01). CONCLUSIONS: Serum cortisol and sAA levels are increased during pregnancy. During the luteal phase of the ovarian cycle, salivary cortisol levels increase, whereas serum cortisol and sAA levels decline.

Prevalência das dermatopatias não-tumorais em cães do município de Santa Maria, Rio Grande do Sul (2005-2008)

Este estudo teve como objetivo principal determinar a prevalência das dermatopatias não-tumorais que acometem cães do município de Santa Maria, Rio Grande do Sul, Brasil. Para isso, foram acompanhados os atendimentos dermatológicos no Hospital Veterinário Universitário, Universidade Federal de Santa Maria, e em um consultório veterinário particular no período de março de 2005 a junho de 2008. Durante esse período foram atendidos 480 cães com problemas dermatológicos, desses, em 393 (81,9%) foi possível estabelecer o diagnóstico definitivo e em 87 (18,1%) o diagnóstico não foi conclusivo. Esses 393 cães com diagnóstico conclusivo totalizaram 502 diagnósticos, sendo 424 diagnósticos primários e 78 diagnósticos secundários. A distribuição dos diagnósticos em relação às categorias de dermatopatias diagnosticadas foi a seguinte: dermatopatias alérgicas (190/502 [37,8%]), dermatopatias bacterianas (103/502 [20,5%]), dermatopatias parasitárias (97/502 [19,3%]), dermatopatias relacionadas ao ambiente (28/502 [5,6%], dermatopatias fúngicas (20/502 [4,0%]), dermatopatias endócrinas (13/502 [2,6%]), defeitos da ceratinização (11/502 [2,2%]), dermatopatias psicogênicas (9/502 [1,8%]), alopecias adquiridas (6/502 [1,2%]), dermatopatias auto-imunes (6/502 [1,2%]), dermatopatias hereditárias (6/502 [1,2%]), anormalidades pigmentares (1/502 [0,2%], dermatopatias nutricionais (1/502 [0,2%]) e outras dermatopatias (11/502 [2,2%]). No geral, as 10 principais dermatopatias não-tumorais, em ordem decrescente de freqüência, foram: atopia, dermatite alérgica à picada de pulga, foliculite bacteriana superficial, sarna demodécica, foliculite bacteriana profunda/furunculose, sarna sarcóptica, miíase, alergia alimentar, dermatite piotraumática e malassezíase. Essas 10 condições perfizeram juntas aproximadamente três quartos de todas as doenças de pele de cães diagnosticadas neste estudo.

Smoking during pregnancy and fetal brain development

Background: Although the knowledge of adverse effects of smoking during pregnancy has increased in recent years, more research is needed to gain a better understanding of the effects of smoking during pregnancy. Smoking exposure is the most common preventable factor that causes adverse pregnancy outcomes. Aims and Methods: First, data on smoking habits during pregnancy from the Nordic Medical Birth Registers was used to study the national differences in trends of smoking during pregnancy. Second, the effects of prenatal smoking exposure on fetal brain development, assessed by brain MRI at term age, were studied by using data from the multidisciplinary PIPARI Study consisting of a 6-year cohort of VLBW/VLGA infants (n = 232, of which 18.1% were exposed to prenatal smoking) born in Turku University Hospital, Finland. Third, the effects of prenatal smoking exposure on psychiatric morbidity and use of psychotropic medication were studied in a cohort of children born from 1987–1989 in Finland (n = 175,869, of which 15.3% were exposed). The data used were obtained from population-based longitudinal registers from the National Institute of Health and Welfare, the Statistics Finland, and the Finnish Social Insurance Institution. Results: Smoking rates during pregnancy differed considerably between the countries. Smoking rates were highest among teenagers and women with lower socioeconomic positions. The smoking prevalence was found to be increasing among teenagers in both Finland and Norway. Prenatal smoking exposure was associated with smaller frontal lobe and cerebellar volumes in preterm infants. A clear association was found between prenatal smoking exposure and psychiatric morbidity treated with specialized hospital care and the use of various psychotropic medications. Conclusions: Prenatal smoking exposure had adverse effects on fetal brain development. These effects might explain part of the association found between smoking exposure and psychiatric problems in later life. Our study suggests that prenatal smoking exposure is linked with both mild and severe psychiatric problems. This study emphasizes the importance of efforts to reduce smoking during pregnancy.

Composite artistry in the Book of Numbers : a study in biblical narrative conventions

The present thesis discusses the coherence or lack of coherence in the book of Numbers, with special regard to its narrative features. The fragmented nature of Numbers is a well-known problem in research on the book, affecting how we approach and interpret it, but to date there has not been any thorough investigation of the narrative features of the work and how they might contribute to the coherence or the lack of coherence in the book. The discussion is pursued in light of narrative theory, and especially in connection to three parameters that are typically understood to be invoked in the interpretation of narratives: 1) a narrative paradigm, or ‘story,’ meaning events related to each other temporally, causally, and thematically, in a plot with a beginning, middle, and end; 2) discourse, being the expression plane of a narrative, or the devices that an author has at hand in constructing a narrative; 3) the situation or languagegame of the narrative, prototypical examples being factual reports, which seeks to depict a state of affairs, and storytelling narratives, driven by a demand for tellability. In view of these parameters the present thesis argues that it is reasonable to form four groups to describe the narrative material of Numbers: genuine narratives (e.g. Num 12), independent narrative sequences (e.g. Num 5:1-4), instrumental scenes and situations (e.g. Num 27:1-5), and narrative fragments (e.g. Num 18:1). These groups are mixed throughout with non-narrative materials. Seen together, however, the narrative features of these groups can be understood to create an attenuated narrative sequence from beginning to end in Numbers, where one thing happens after another. This sequence, termed the ‘larger story’ of Numbers, concerns the wandering of Israel from Sinai to Moab. Furthermore, the larger story has a fragmented plot. The end-point is fixed on the promised land, Israel prepares for the wandering towards it (Num 1-10), rebels against wandering and the promise and is sent back into the wilderness (Num 13-14), returns again after forty years (Num 21ff.), and prepares for conquering the land (Num 22-36). Finally, themes of the promised land, generational succession, and obedience-disobedience, operate in this larger story. Purity is also a significant theme in the book, albeit not connected to plot in the larger story. All in all, sequence, plot, and theme in the larger story of Numbers can be understood to bring some coherence to the book. However, neither aspect entirely subsumes the whole book, and the four groups of narrative materials can also be understood to underscore the incoherence of the work in differentiating its variegated narrative contents. Numbers should therefore be described as an anthology of different materials that are loosely connected through its narrative features in the larger story, with the aim of informing Israelite identity by depicting a certain period in the early history of the people.

Avaliação de diferentes herbicidas para erradicação química de coqueiros infectados com resinose

Objetivou-se neste trabalho selecionar herbicidas que possam ser utilizados na erradicação química de coqueiros infectados com resinose. O experimento foi instalado no município de Neópolis - SE, no período de junho a julho de 2007. Utilizou-se uma população de coqueiros da variedade anão-verde, implantada há 11 anos. O delineamento experimental foi o inteiramente casualizado, em parcelas subdivididas no tempo, com cinco repetições (cada unidade experimental foi composta por um coqueiro infectado). Os tratamentos foram formados pela combinação de dez tratamentos herbicidas {MSMA (36 g por planta); glyphosate (18 g por planta); paraquat (10 g por planta); [2,4-D + picloram] (18 + 1,125 g por planta); [2,4-D + picloram] + paraquat ([9 + 0,5625] + 5 g por planta); MSMA + glyphosate (18 + 9 g por planta); MSMA + paraquat (18 + 5 g por planta); glyphosate + paraquat (9 + 5 g por planta); [2,4-D + picloram] + MSMA ([9 + 0,5625] + 18 g por planta); tratamento controle (testemunha) sem aplicação} e de quatro épocas de avaliação (7, 14, 21 e 28 dias após a aplicação dos tratamentos herbicidas). Os herbicidas foram injetados no estipe dos coqueiros em um furo de 25 cm de profundidade, 5 cm de diâmetro e inclinação de 45º, localizado a 1,0 m de altura. A aplicação foi realizada por intermédio de uma seringa graduada, imediatamente após a abertura dos furos, sendo os herbicidas aplicados sem diluição. Foram realizadas quatro avaliações da dessecação dos coqueiros, aos 7, 14, 21 e 28 dias após a aplicação dos tratamentos (DAA). O herbicida MSMA foi o que resultou na dessecação mais rápida dos coqueiros doentes, além de promover a morte de todas as plantas avaliadas, sendo por isso o tratamento mais indicado na continuação dos estudos visando à proposição de uma técnica para a erradicação química de coqueiros infectados com resinose.
