ABSTRACT

This study aimed to compare the feed efficiency (FE) and physiological parameters of Holstein and crossbred Holstein × Simmental cows in a confinement system during winter and summer. The study was conducted in a dairy farm in southern Brazil by including a total of 48 multiparous cows. The cows were studied for 21 days in two periods, summer and winter, and their daily dry matter intake (DMI), milk yield (MY), rectal temperature (RT), respiratory rate (RR), body weight, and body condition score were recorded. An analysis of variance was conducted using the SAS statistical package. The results showed that crossbred Holstein × Simmental cows have a similar FE as Holstein cows in a high-production system (1.83 × 1.81 kg DMI/kg MY, respectively), and they can achieve the same production levels as purebred Holstein cows (43.8 vs. 44.5 milk/cow/day). Our findings indicated a difference for the period as both genetic groups achieved higher FE in winter than in summer (1.98 vs. 1.67 DMI/kg MY, respectively). In addition, we found evidence that crossbred cows are better at dissipating body heat during heat-stress situations, as they have higher RR in summer compared to purebred cows, while Holstein cows have higher RT in summer afternoons than crossbred cows. Therefore, using crossbred Holstein × Simmental cows is an alternative for high-production systems.

ABSTRACT

This study aimed to characterize the quantitative and qualitative damage caused by Deois flexuosa (Walker) (Hemiptera: Cercopidae) adults in Axonopus catharinensis cv. SCS 315 Catarina and Cynodon dactylon (Tifton 85 and Jiggs cultivars) under different infestation densities and, consequently, the expression of tolerance-type resistance. For this purpose, potted plants were infested with different insect densities (0, 5, 10, 20, and 40 adults m-2). The impact of the infestation levels was assessed in the first growth cycle (10-day coexistence period) and in the regrowth (40 days after the first cut, without infestation) based on crop yield and chemical-bromatological composition as well as on photosynthetic pigments and hydrogen peroxide content. The principal component analysis relating infestation density and chemical-bromatological parameters showed a positive correlation between infestation density of D. flexuosa and the contents of neutral detergent fiber, acid detergent fiber, and the dry matter (DM). On the other hand, infestation density inversely correlated with the tillering rate, photosynthetic pigments (chlorophyll a and b, carotenoids), and iron content. In general, the impacts on DM production and chemical-bromatological composition were lower in A. catharinensis cv. SCS 315 Catarina when compared to the Cynodon species, possibly because A. catharinensis has higher tillering capacity and does not show a reduction in the photosynthetic pigments, which may act as compensating factors to D. flexuosa damage. Our results demonstrate that the A. catharinensis cultivar expresses tolerance-type resistance to D. flexuosa and constitutes an interesting option for pasturelands formation and diversification where this spittlebug species is an emerging pest.

ABSTRACT

ABSTRACT: Urban environments are contaminated in many ways with persistent organic and inorganic pollutants as a result of anthropogenic activities, endangering human health and natural resources. The objective of the present study was to evaluate the soil contamination by cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) in 10 vegetable gardens of urban schools located near or on Botucatu sandstone outcrops of Guarani Aquifer in the urban areas of Lages, Santa Catarina, Brazil. In each garden, three soil samples at each position (in the soil immediately outside and the soil in the garden) were collected at a depth of 0-20 cm. The ISO 11466 method was used to extract the metals. Inductively coupled plasma optical emission spectrometry was used to quantify the elements and certified materials to evaluate the quantities (SRM 2709a - San Joaquin Soil - NIST). To evaluate the data, principal component analyses and cluster analyses were performed. The cluster analysis for the evaluated metals showed that the highest contents of elements were reported in three gardens. Values above the prevention value defined by resolution no. 420/2005 of the National Council for the Environment -Conselho Nacional do Meio Ambiente (CONAMA) - were reported for cobalt in one garden and copper in three gardens; thus, these areas were categorized as Class III areas. Principal component analysis explained 74.7% of the data and showed the enrichment of some elements within gardens.


RESUMO: Ambientes urbanos são contaminados de muitas maneiras com poluentes orgânicos e inorgânicos persistentes como resultado de atividades antrópicas, colocando em risco a saúde humana e os recursos naturais. O objetivo do presente estudo foi avaliar a contaminação do solo por cobalto (Co), cromo (Cr), cobre (Cu), manganês (Mn), níquel (Ni), chumbo (Pb) e zinco (Zn) em 10 hortas de escolas urbanas situadas próximo ou sobre áreas de afloramento de arenito Botucatu do Aquífero Guarani, no município de Lages, Santa Catarina. Em cada horta, três amostras de solo foram coletadas (dentro e fora da horta) na profundidade de 0-20 cm. O método ISO 11466 foi usado para extrair os metais. Utilizou-se espectrometria de emissão óptica com plasma indutivamente acoplado (ICP OES) para quantificar os elementos e materiais certificados (SRM 2709a - San Joaquin Soil - NIST). Para avaliar os dados foi feita a análise dos componentes principais e análise de agrupamento. Pela análise de agrupamento para os metais avaliados observou-se que as maiores concentrações de elementos foram encontradas em três hortas. Valores acima do valor de prevenção (PV) definido pela resolução no. 420/2005 do Conselho Nacional do Meio Ambiente (CONAMA) foram encontrados para Co em uma horta e Cu em três hortas, classificando essas áreas como classe III. A análise de componentes principais explicou 74,7% dos dados e mostrou o enriquecimento de alguns elementos dentro das hortas.

ABSTRACT

BACKGROUND: This study assessed the use of low-energy laser in the prevention or reduction of the severity of oral mucositis. PROCEDURE: A randomized clinical trial was carried out. Patients from 3 to 18 years of age treated with chemotherapy or hematopoietic stem-cell transplantation between May, 2003 and February, 2005 were eligible. The intervention group received laser application for 5 days following the start of chemotherapy. The grade of oral mucositis was assessed by the WHO per NCI-CTC common toxicity criteria and the assessments were made on days 1, 8 and 15 by a trained examiner blind to the intervention. RESULTS: Sixty patients were evaluable for analysis; thirty-nine (65%) were males, 35 (58%) patients had a diagnosis of leukemia or lymphoma, and 25 (42%) had solid tumors. The mean age was 8.7 +/- 4.3 years. Twenty-nine patients were randomized in the laser group and 31 in the control group. On day 1, no patients presented with mucositis. On day 8, of 20 patients (36%) who developed mucositis, 13 of them were from the laser group and 7 from the control group. On day 15, of 24 patients (41%) who developed mucositis, 13 of them were from the laser group and 11 from the control group. There was no significant difference between groups concerning the grades of mucositis on day 8 (P = 0.234) or on day 15 (P = 0.208). CONCLUSIONS: This study showed no evidence of benefit from the prophylactic use of low-energy laser in children and adolescents with cancer treated with chemotherapy when optimal dental and oral care was provided.

ABSTRACT

The CNS is a frequent site of relapse of childhood acute lymphoblastic leukemia (ALL). Traumatic lumbar puncture (TLP) is thought to increase the risk of CNS relapse. The authors examined whether TLP at the time of diagnosis affected outcome and whether this effect was influenced by the timing of intrathecal therapy (IT) in 77 patients with newly diagnosed ALL. IT was instilled at the time of either the diagnostic LP (early) or a second LP 24--48 h later (delayed). Of the 19 patients who had a TLP at diagnosis and received late IT therapy, 6 had isolated CNS relapse and 2 had combined CNS and bone marrow (BM) relapse. Of the 9 patients who had TLP and received early IT therapy, 1 had a CNS relapse (p=.20). In an analysis stratified according to risk of relapse, the odds ratio (OR) for relapse was 0.8 among patients at low and standard risk who had delayed IT therapy after TLP (p=.99) vs. 0.17 for those who had early IT (p=.47). Importantly, among patients with high-risk ALL, the OR for relapse was 21.0 for delayed IT therapy (p=.09) and only 1.5 for early IT therapy after TLP (p=.99). The results indicate that TLP at diagnosis appears to increase the risk of CNS relapse markedly in patients with high-risk ALL, and the use of early IT therapy appears to reduce this risk. These findings need to be confirmed by prospective, randomized studies.

ABSTRACT

Infective endocarditis (IE) is rare in children but is associated with substantial morbidity/mortality. Medical records of 161 new patients admitted to the Pediatric Oncology Unit in a 2 years period were reviewed to identify patients with a diagnosis of IE following the Duke criteria. Nine patients developed IE; their ages ranged from 2.4 to 11.3 years. The patients received treatment according to the results of blood cultures. TIPs are associated with a high rate of IE. The diagnosis of IE should be considered in children with cancer who have major/minor criteria as defined by the Duke criteria.

ABSTRACT

OBJECTIVE: To identify the clinical features in osteosarcoma and to investigate their influence on the prognosis of children and adolescents presenting this disease. MATERIAL AND METHODS: The records of children and adolescents with osteosarcoma treated by the Bone Tumors Group of the state of Rio Grande do Sul, Brazil, between January 1992 and December 2001 were reviewed. RESULTS: Fifty consecutive patients were included in this study. Mean age at diagnosis was 13 years (3-22); 68% of the patients were males. The primary site of disease was the femur in 50% of the patients, tibia in 30%, pelvis in 4%, humerus in 10%, fibula in 2% and other sites in 4%. Nineteen patients presented metastases at diagnosis (38%). All patients received chemotherapy and were treated with three different schemes. As for surgical treatment, 26 patients (52%) had an amputation and 17 (34%) received conservative surgery. Serum lactic dehydrogenase > 1,000 UI/ml (p = 0.0159, log rank), tumor necrosis < 90% and presence of metastases had a negative influence on prognosis. The overall 5-year survival was of 33.2+/-7.2% with mean follow-up of 36 months (6-126). Event-free survival was 29.7+/-7%. The 5-year event-free survival in non-metastatic patients was 45+/-10.7%, and zero in metastatic patients (follow-up of 78.4 and 18.7 months, respectively). Only two out of 19 metastatic patients are alive and free of disease at 18 and 30 months respectively. CONCLUSION: Metastatic disease at diagnosis, serum levels of serum lactic dehydrogenase > 1,000 UI/ml and tumor necrosis < 90% are predictors of unfavorable prognosis. The excessively high incidence of metastatic patients may suggest the presence of an aggressive pattern of disease in our population, or may indicate late diagnosis.

ABSTRACT

OBJETIVOS: Conhecer as características clínicas e determinar os fatores de importância prognóstica de crianças e adolescentes com osteossarcoma. MATERIAIS E MÉTODOS: Foram revisados os prontuários de crianças e adolescentes com diagnóstico de osteossarcoma tratados entre janeiro de 1992 e dezembro de 2001 pelo Grupo de Tumores Osseos do Rio Grande do Sul. RESULTADOS: Foram incluídos no estudo 50 pacientes com idade mediana de 13 anos (3 a 22), sendo 68 por cento pacientes do sexo masculino. Os locais primários foram: 50 por cento fêmur, 30 por cento tíbia, 4 por cento ilíaco, 10 por cento úmero, 2 por cento fíbula e 4 por cento outros . Dezenove pacientes (38 por cento) apresentavam metástases ao diagnóstico. Todos os pacientes foram submetidos a quimioterapia. Quanto ao tratamento cirúrgico, 26 pacientes (52 por cento) foram submetidos a amputação, e 17 a cirurgia conservadora (34 por cento). A desidrogenase láctica maior do que 1.000 UI/ml ao diagnóstico, o índice de necrose inferior a 90 por cento e a presença de metástases influíram negativamente no prognóstico. A probabilidade de sobrevida global em 5 anos foi de 33,2+7,2 por cento, com média de follow-up de 36 meses (6-126); a probabilidade de sobrevida livre de eventos em 5 anos foi de 29,7+7 por cento. A probabilidade de sobrevida livre de eventos em 5 anos dos pacientes não-metastáticos ao diagnóstico foi de 45+10,7 por cento, e a dos metastáticos foi zero (médias de follow-up de 78,4 e 18,7 meses, respectivamente); apenas dois dos 19 pacientes com doença metastática encontram-se fora de tratamento e livres de doença, com follow-up de 18 e 30 meses, respectivamente. CONCLUSAO: A presença de doença metastática e nível sérico de desidrogenase láctica acima de 1.000 UI/ml ao diagnóstico, assim como índice de necrose < 90 por cento, representam fatores prognósticos desfavoráveis. O percentual excessivamente elevado de pacientes com doença metastática ao diagnóstico sugere que se trata de uma população de pacientes com doença biologicamente agressiva ou diagnosticados tardiamente em nosso meio.

ABSTRACT

O objetivo deste trabalho é demonstrar a aferição do risco relativo entre associação do Helicobacter pylori(Hp) e a úlcera péptica duodenal em endoscopias digestivas realizadas em Caxias do Sul, no período de janeiro de 1994 a dezembro de 1996. A presença do Helicobacter pylori foi demonstrada em fragmentos de biópsias colhidas de antro digestivo através do teste da uréase pré-formada. De um total 4.184 endoscopias, 1.838(44 por cento) eram uréase-negativas e 2.346(56 por cento), uréase-positivas. Dos pacientes portadores de úlcera duodenal ao exame endoscópico, 43 eram uréase-negativos e 274 eram uréase-positivos

ABSTRACT

A correlação entre o Helicobacter pylori e as neoplasias epiteliais gásticas, reconhecida pela Organiação Mundial de Saúde, é decorrente de estudos epidemiológicos, baseados fundamentalmente na positividade dos anticorpos anti-helicobacter pylori. Poucos estudos prospectivos baseados no achado direto ou indireto desta bacteria na mucosa gástrica de pacientes portadores de carcinomas gástricos foram levados a cabo. Restam dúvidas,portanto, acerca da importância e da universalidade desta associação. O presente estudo, baseado no teste rápido da urease pré-formada como forma de screening para o Helicobacter pylori e sua confirmação histológica nos casos de neoplasias gástricas, envolvendo um total de 5.227 exames endoscópicos realizados e um total de 35 adenocarcinomas gástricos detectados, demonstra um risco relativo da associação de 0,37, sugerindo que a subpopulação em estudo, composta basicamente de descendentes de imigrantes italianos, apresentam baixo risco de carcinogênese gástrica associada ao Helicobacter pylori

ABSTRACT

A correlaçao entre o Helicobacter pylori e as neoplasias epiteliais gástricas, reconhecida pela Organizaçao Mundial de Saúde, é decorrente de estudos epidemiológicos extensos, baseados fundamentalmente na positividade dos anticorpos anti-Helicobacter pylori. Poucos estudos prospectivos baseados no achado direto ou indireto desta bactéria na mucosa gástrica de pacientes portadores de carcinomas gástricos foram levados a cabo. Restam dúvidas, portanto, acerca da importância e da universalidade desta associaçao. O presente estudo, baseado no teste rápido da urease pré-formada como forma de screening para o Helicobacter pylori e sua confirmaçao histológica nos casos de neoplasias gástricas, envolvendo um total de 5227 exames endoscópicos realizados em um total de 35 adenocarcinomas gástricos detectados, demonstra um risco relativo da associaçao de 0,37, sugerindo que a subpopulaçao em estudo, composta básicamente de descendentes de imigrantes italianos apresenta baixo risco de carcinogênese gástrica associada ao Helicobacter pylori.

ABSTRACT

Os autores analisam a incidência de constipaçao intestinal e encoprese em 252 crianças que aguardavam consulta no ambulatório de Pediatria do Hospital Materno Infantil Presidente Vargas (HMIPV) e que nao apresentavam qualquer queixa relativa ao aparelho digestivo. Neste estudo, 200 (79,36 por cento) crianças apresentam hábito intestinal normal, e 52 (20,64 por cento) relatam problemas de constipaçao. Observou-se que, do total de crianças constipadas, 6 (11,5 por cento) tinham encoprese e 45 (86,3 por cento) apresentavam fezes sibalosas. Foram avaliados também outros aspectos clínicos, tais como a idade do início da educaçao esfincteriana e a importância dada a este sintoma pela mae ou responsável.

ABSTRACT

A disciplina de Urologia do Curso de graduaçao em Medicina da Universidade de Caxias do Sul, em associaçao com o Instituto de Previdência e Assistência Municipal (IPAM) realizou, no período de outubro a dezembro de 1996, uma campanha para detecçao do carcinoma prostático entre seus beneficiários. Esta campanha teve por objetivo incentivar homens com idade superior a 45 anos a iniciarem avaliaçoes anuais para detecçao precoce desta neoplasia. O objetivo deste trabalho foi o de demonstrar a necessidade de diagnóstico precoce e o de identificar os métodos mais adequados para a sua detecçao. Dos 1.300 homens com idade superior a 45 anos mobilizados nesta campanha, 280 procuraram médicos urologistas assistentes e conveniados àquela entidade previdenciária; neste grupo, foram diagnosticados 4 carcinomas da próstata, sendo que 3 eram assintomáticos e 1 apresentava sintomas obstrutivos.

ABSTRACT

Os autores procuram relacionar, nesta revisao, as causas inerentes ao acidente vascular cerebral isquêmico em adultos jovens, com vistas a ressaltar os principais aspectos que envolvem essa patologia na faixa etária referida. O infarto cerebral é pouco freqüente no adulto jovem e as lesoes causais sao, em geral, facilmente tratáveis. Este será o principal aspecto a ser aprofundado neste estudo, embora se observe baixa incidência de complicaçoes na populaçao abordada. Segundo a literatura, o território vascular mais freqüentemente comprometido, no adulto jovem, é o da artéria carótida interna; já, o principal fator de risco considerado é a hipertensao arterial sistêmica. Salienta-se, entretanto, que cerca de 35 por cento dos casos de infarto cerebral no adulto jovem permanecem ainda sem diagnóstico (Hart e Miller, 1985).

ABSTRACT

Nosso objetivo foi avaliar o bloqueio peridural torácico associado à sedaçao com midazolam para mamoplastia única ou associada a outro procedimento de cirurgia plástica. Foram estudadas 127 pacientes ASA I e II. Todas foram submetidas a uma punçao peridural torácica T6-T7 ou T7-T8. Muitas realizaram procedimentos concomitantes, como lipoaspiraçao, abdominoplastia, etc.. O anestésico empregado foi bupivacaína em concentraçao entre O,18 e O,20 por cento sem vasoconstritor. Em metade dos pacientes foi utilizado fentanil (lOO microgramas) junto ao anestésico local. Os autores concluem que a técnica é válida desde que seja conduzida com cuidados rigorosos de monitorizaçao, fracionando as doses anestésicas e nao usando opiáceos para a sedaçao das pacientes.
