ABSTRACT

@#Introduction: Many surgical approaches have been described for hip hemiarthroplasty (HHA) treating femur neck fractures (FNFs). Direct lateral approach (DLA) is one of the most used. Today, the direct anterior approach (DAA) has become very attractive, but it seems to involve more intra-operative fractures. Our main endpoint was to demonstrate that the DAA may be a valid alternative comparing to the DLA. Materials and methods: Patients affected by FNFs and treated with HHA between the years 2016 and 2020 were studied. We divided the treatment of the fractures according to the surgical approach. The analysis was focused on perioperative complications and radiological outcomes. Results: There were a total of 166 patients. The DLA group included patients with an average age of 83.5 years and the DAA group of 83 years. We found similar surgical times (DLA 67 min vs DAA 61 min; p = 0,55), number of transfusions (DLA 3/person vs DAA 4/person; p = 0,91), perioperative complications (fractures: DLA 0 vs DAA 0 – dislocations: DLA 2,50% vs DAA 0) and functional outcomes (HHS: DLA 83 points vs DAA 87 points; p = 0,71). There were no statistical differences comparing diaphyseal filling (Canal Fill Index at the proximal third: DLA 0,79 vs DAA 0,78; p= 0,24), bone loss (Paprosky I: DLA 96,25% vs DAA 91,86%; p = 0,47) and prevalence of heterotopic ossification (Broker low degree: DLA 93,75% vs 95, 34%; p = 0,87). Conclusion: Analysing perioperative complications and studying post-operative radiographic evolution, our results suggest that the DAA is a valid alternative to the DLA in HHA treating FNFs.

ABSTRACT

Among the tumors affecting the choroid plexus in dogs, the papilloma ranks second place in incidence after cell carcinoma tumors. Presumptive diagnosis can be made through imaging methods, such as computed tomography and magnetic resonance images. Definitive diagnosis of plexus choroid tumor is based on histopathological findings. This report presented the tomographic features of the brain in a 6-year-old intact female Rottweiler with choroid plexus papilloma. The computed tomography showed right lateral ventricle enlargement, midline deviation and an enhanced mass into the postcontrast phase. At necropsy, a mass on the floor of the right lateral ventricle was observed, associated with important ventricle dilatation. The histopathological analysis demonstrated the presence of neoplastic cell forms with papillary projections. The computed tomography proved to be an effective tool in the presumptive diagnosis of this kind of cerebral disorder.


Dentre os tumores que afetam o plexo coroide em cães, o papiloma figura como o segundo tipo de maior incidência, antecedido apenas pelo carcinoma. O diagnóstico presuntivo pode ser elaborado por meio de métodos de imagem, como a tomografia computadorizada e a ressonância magnética. O diagnóstico definitivo de tumor do plexo coroide é estabelecido com base nos achados histopatológicos. Relatamos os aspectos tomográficos do crânio em uma fêmea de 6 anos, inteira, da raça Rottweiler, com papiloma do plexo coroide. A tomografia computadorizada revelou dilatação do ventrículo lateral direito, desvio da linha média e a presença de uma massa, que sofreu realce na fase pós-contraste. À necropsia, foi observada uma massa sobre o assoalho do ventrículo lateral direito, associada à importante dilatação ventricular. A análise histopatológica demonstrou a presença de células poligonais neoplásicas, arranjadas em papilas longas. A tomografia computadorizada apresentou-se como uma ferramenta eficaz no diagnóstico presuntivo desse tipo de alteração cerebral.

ABSTRACT

Avaliaram-se o consumo e a digestibilidade de nutrientes por novilhos Nelore suplementados com elevado teor de proteína na terminação, em pasto, durante a seca. Foram utilizados quatro novilhos com 30 meses e peso médio inicial de 440kg, distribuídos em quadrado latino 4x4 (quatro níveis de suplementação e quatro períodos de 16 dias). Foram usados quatro piquetes de um hectare de capim Panicum maximum cv. Tanzânia, e os animais receberam: 0 (grupo-controle); 1,0; 2,0; ou 4,0kg de suplemento/dia. Os suplementos, à exceção do controle, apresentaram níveis decrescentes de proteína bruta (58 a 32 por cento da matéria seca) e proporções de mistura mineral:ureia:farelos de 10:10:80, 5:5:90 e 2,5:2,5:95 para os respectivos tratamentos. O consumo e a digestibilidade foram determinados com o uso do óxido crômico e FDAi, o delineamento estatístico foi em quadrado latino, e os tratamentos foram avaliados pela análise de regressão. Houve efeito linear crescente sobre o consumo e sobre os coeficientes de digestibilidade da matéria seca, proteína bruta, extrato etéreo e fibra em detergente neutro, e sobre o consumo de nutrientes digestíveis totais. Não houve efeito sobre o consumo de pasto e o consumo e a digestibilidade dos carboidratos não fibrosos. Os suplementos avaliados em geral melhoraram o consumo e a digestibilidade e, consequentemente, o valor nutritivo da dieta de novilhos em terminação sob pastejo, no período da seca.


The effects of supplements with high protein content on intake and digestibility were evaluated in Nellore steers finished at pasture during the dry season. Four steers avering 30-month old and initial weight of 440kg were distributed in a 4x4 Latin square (four levels of supplementation and four periods of 16 days). Four paddocks of one hectare containing Panicum maximum cv. Tanzania grass were utilized and the animals received 1.0, 2.0, or 4.0kg of supplement/day, in addition to a control - mineral mixture. The supplements, except control, presented decreasing levels of crude protein (58 to 32 percent in dry matter) and the proportions of mineral mixture:urea:cereal meals were 10:10:80, 5:5:90, and 2.5:2.5:95 for the treatments. The intake and digestibility were determined with the use of chromium oxide and ADFi. The statistical design was Latin square and the treatments were evaluated by regression analysis. There was an increasing linear effect on the intakes and digestibility coefficients of dry matter, crude protein, ether extract, neutral detergent fiber, and intake of total digestible nutrients. There was no effect on the intake of pasture and intake and digestibility of non-fiber carbohydrates. It can be concluded that the evaluated supplements generally improve the intake and digestibility and consequently the nutritive value of the diets of finishing animals on the pasture during the dry season.

ABSTRACT

Avaliaram-se o ganho de peso e as características de carcaça de novilhos Nelore suplementados com elevado teor de proteína na terminação em pasto, durante a seca, e estimou-se a disponibilidade dos componentes da pastagem. O experimento foi implantado em pastagem de Brachiaria brizantha, cv. Marandu, em seis piquetes de nove hectares. Foram utilizados 48 novilhos Nelore com 30 meses de idade e 415±16 kg. Cada lote, alojado em um piquete, foi pesado no início e a cada 21 dias, durante 84 dias. A suplementação constou de: 0 (grupo-controle); 0,25; 0,5; 1,0; 2,0; ou 4,0 kg/animal/dia. Os suplementos, à exceção do controle, apresentaram porcentagens decrescentes de proteína bruta (111 a 32 por cento da matéria seca) e proporções de mistura mineral:ureia:farelos de 25:25:50; 15:15:70; 10:10:80; 5:5:90 e 2,5:2,5:95, para os respectivos tratamentos. O delineamento foi o inteiramente ao acaso e os tratamentos foram avaliados pela análise de regressão. A proporção de colmo e folha seca aumentou no decorrer dos períodos experimentais, caracterizando o déficit hídrico da estação seca. Houve efeito linear crescente sobre o peso vivo final, ganho médio diário, peso de carcaça, espessura de gordura subcutânea e rendimento de carcaça em função do consumo de suplemento. A conversão do suplemento em kg/kg de ganho de peso, de 10:1, é típica de suplementação energética, mostrando que os animais não responderam satisfatoriamente à suplementação proteica.


Daily gain and carcass traits of Nellore steers fed different levels of supplementation with high content of protein at finishing during the dry season and the availability of the components of the pasture were evaluated. The experiment was carried out on pasture of Brachiaria brizantha, cv. Marandu, in six paddocks of nine hectares. Forty-eight Nellore steers averaging 30-month old and 415+16kg were used. Each group was allocated in a paddock, being weighted in the beginning and every 21 days, during 84 days. The levels of supplements were: 0.25, 0.5, 1.0, 2.0, and 4.0kg/animal/day, in addition to a control (mineral mixture). The supplements, except the control, presented decreasing levels of crude protein (111 to 32 percent of the dry matter) and proportions of mineral mixture:urea:concentrate feeds of 25:25:50, 15:15:70, 10:10:80, 5:5:90, and 2.5:2.5:95, respectively. The statistical design was completely randomized and the treatments were evaluated by regression analysis. The proportion of stem and dead leaf increased in elapsing of the experimental periods characterizing water deficit in the dry season. There was increasing linear effect on the final live weight, average daily gain, carcass weight, fat thickness, and carcass yield as a function of supplement intake. The supplement conversion in kg/kg of weight gain, at 10:1, is typical of energetic supplementation, showing that the animals did not satisfactorily respond to protein supplementation, which would give better values of conversion.
