Efeito do exercício na biomecânica da marcha em crianças e adolescentes com paralisia cerebral

Tipo de Estudo: Revisão. Temática: Efeito do exercício na biomecânica da locomoção de crianças e adolescentes com paralisia cerebral que apresentam marcha em agachamento (designada como “crouch gait”). Objetivos: 1) verificar e analisar as metodologias de programas de treino de força que, combinados ou não com outros programas de treino, exercícios ou intervenções, visam melhorar o padrão da marcha e a funcionalidade destes indivíduos; 2) tendo por base os resultados do primeiro objetivo, compilar uma bateria de exercícios e propôr um exemplo de plano de treino adequado a esta população. Métodos: Usou-se o PICOS para a definição de uma estratégia de busca segura e confiável. A “PubMed”, “Cochrane” e “Web of Knowledge", foram as bases de dados selecionadas e utilizadas. A pesquisa aconteceu na Faculdade de Motricidade Humana e no Hospital de Santa Maria em Lisboa. A seleção final dos artigos decorreu no mês de Janeiro, durante uma semana, e foi realizada e rastreada por dois investigadores de forma diferente. Incluíram-se nesta revisão estudos randomizados e controlados, com crianças e adolescentes com paralisia cerebral e que apresentam “crouch gait”, e nos quais foram utilizados protocolos de exercício como método de intervenção nesta população, tendo em vista a melhoria do padrão de marcha. Resultados: Da pesquisa inicial resultaram 223 estudos. Com a leitura dos resumos, selecionaram-se 96. Excluíram-se 85 porque apenas 11 cumpriram com todos os critérios de eligibilidade. Foi avaliada a qualidade metodológica destes 11 estudos com a escala PEDro e excluíram-se 3, resultando em 8 artigos como potenciais estudos para a revisão. Discussão: Um melhor alinhamento biomecânico e a obtenção de uma base mais estável podem afetar positivamente a função da marcha nestas crianças. O treino da força, sozinho, nem sempre melhora a capacidade da marcha. A melhoria da marcha advém dos efeitos e resultados significativos da força muscular, da amplitude de movimento articular, da diminuição da espasticidade, da regulação do tónus e da melhoria do equilíbrio e da postura. Conclusão: O treino da força não é uma contra indicação para estes indivíduos. Este oferece efeitos benéficos para a melhoria das suas funcionalidades. Para um efeito significativo, a intervenção deve ser superior a seis (6) semanas.

Ecoepidemiología de Chlamydophila psittaci, pecorum, pneumoniae, abortus en Córdoba. Eco-epidemiology of Chlamydophila psittaci, pecorum, pneumoniae, abortus in Córdoba.

Las Clamidias son bacterias patógenas de los animales de producción, de vida silvestre y de compañía. Además de las pérdidas económicas que producen las infecciones en los planteles de producción bovina, ovina, caprina, porcina y aves de corral, la mayoría de las especies tienen importancia zoonótica, pudiendo dar origen a infecciones graves, potencialmente letales en el ser humano. El orden Chlamydiales está integrado por bacterias que actúan como parásitos intracelulares obligados que desarrollan su ciclo de vida únicamente dentro de inclusiones citoplasmáticas. En este orden se encuentra la familia Chlamydiaceae que comprende dos géneros, Chlamydia y Chlamydophila; y las especies, Chlamydia trachomatis, C. suis, C. muridarum, Chlamydophila psittaci, C. abortus, C. felis, C. caviae, C. pecorum, y C. pneumoniae. C. psittaci causa psitacosis o clamidiosis aviar. En Argentina, los primeros casos clínicos de psitacosis fueron reportados en 1929. Los criadores de aves y quienes las poseen como mascotas, representan el grupo de mayor riesgo; pero también las personas que trabajan en pajarerías y aquellas que por su empleo se ven expuestas a contraer la enfermedad (empleados en peladeros donde se carnean y procesan pollos y otras aves para consumo, veterinarios, empleados de zoológicos, etc.). La infección en humanos se presenta como una neumonía severa; con fiebre alta, escalofríos, dolor de cabeza, mialgia y dificultad respiratoria. Ocasionalmente puede presentarse vómitos, dolor abdominal, diarrea y complicaciones como miocarditis, endocarditis, encefalitis, ictericia y fallas multiorgánicas, que pueden ser fatales sino se le administra el tratamiento adecuado. La infección en las mujeres embarazadas puede producir neumonía, hepatitis, insuficiencia renal, sepsis, parto prematuro y muerte fetal. Existen más de 465 especies de aves en las que se registró C. psittaci, incluyendo ornamentales, de corral, silvestres, acuáticas y palomas. Las patologías que pueden producir en estos animales son neumonitis, conjuntivitis, encefalomielitis, placentopatías, fetopatías, anorexia, diarrea e infecciones persistentes asintomáticas u oligosintomáticas. En bovinos, C. pecorum, C. abortus y C. psittaci producen infecciones respiratorias y genitales; que se presentan como cuadros de enteritis, artritis, encefalomielitis, endometritis e hipofertilidad. En Argentina, la infección clamidial en el ganado caprino fue asociada a daños en el tejido uterino, abortos, partos prematuros y crías débiles. En equinos, C. psittaci y C. pneumoniae producen abortos y desórdenes respiratorios, con un gran impacto en ganadería que redunda en pérdidas económicas. Considerando que existen escasos estudios eco-epidemiológicos y clínicos que reporten el estado de situación de estas infecciones en nuestro medio, es que el presente trabajo propone actualizar y profundizar el conocimiento de las especies de Clamidias de importancia médico-veterinaria presentes en la provincia de Córdoba, Argentina. El desarrollo de este proyecto aportará la implementación de técnicas que mejorarán el diagnóstico microbiológico, confirmarán los cuadros clínicos; y por lo tanto contribuirá al conocimiento de estos agentes infecciosos en nuestra región. Esta información es indispensable para los organismos responsables de la Salud Pública (Ministerios de Salud y Educación, Municipios, etc.) para que puedan obrar en consecuencia y generar sistemas de alerta temprana, tomar medidas de prevención y medidas de control frente a la presencia de un brote epidémico por alguna cepa clamidial. "Eco epidemiology of Chlamydophila psittaci, C. pecorum and C. pneumoniae: Impact on public health "The Chlamydiae are bacterial pathogens of farm animals, wildlife and pets. Besides the economic losses that occur on campuses infections of cattle, sheep, goats, swine and poultry, most species are zoonotic, infections potentially fatal can cause in humans. The order Chlamydiales is composed of the family Chlamydiaceae comprising two genera, Chlamydia and Chlamydophila, and nine species, Chlamydia trachomatis, C. suis, C. muridarum, Chlamydophila psittaci, C. abortus, C. felis, C. caviae, C. pecorum, and C. pneumoniae. The clinical manifestations in humans are associated with severe pneumonia. Also, nonspecific gastrointestinal symptoms, and complications such as myocarditis, endocarditis, encephalitis, jaundice and multiple organ failure. There are over 465 species of birds where recorded C. psittaci, including ornamental plants, poultry, wild waterfowl and pigeons. Sick birds eliminate chlamydia in all secretions, asymptomatic birds can develop the disease through contact with other infected birds. The human infection occurs by inhalation of aerosolized secretions of infected birds. The prevalence of C. psittaci records in humans, birds, horses, goats and cattle are scarce in Latin America. In Argentina it has been detected chlamydial antibody prevalence in cattle in Buenos Aires and La Pampa (5) and Rockhopper Penguins (Eudyptes chrysocome) in the town of Santa Cruz (11). Detect this pathogen in these birds and learn about potential sources of infection would be of great public health significance. To develop an efficient system of medical and veterinary surveillance is essential to have reliable diagnostic techniques for detection and identification of Chlamydia in birds, animals and humans.

A nutrient balance model for typical Irish farming systems

The twin objectives of the work described were to construct nutrient balance models (NBM) for a range of Irish animal production systems and to evaluate their potential as a means of estimating the nutrient composition of farm wastes. The NBM has three components. The first is the intake of nutrients in the animal's diet. The second is retention or the nutrients the animal retains for the production of milk, meat or eggs. The third is the balance or the difference between the nutrient intake and retention. Data on the intake levels and their nutrient value for dairy cows, beef cattle, pigs and poultry systems were assembled. Literature searches and interviews with National experts were the primary sources of information. NBMs were then constructed for each production system. Summary tables of the nutrient values for the common diet constituents used in Irish animal production systems, the nutrient composition of the animal products and the NBMs (nutrient intake, retention and excretion) for a range of production systems were assembled. These represent the first comprehensive data set of this type for Irish animal production systems. There was generally good agreement between the derived NBMs values and those published in the literature. The NBMs were validated on a number of farms. Data on animal numbers, fertiliser use, concentrates inputs and production output were recorded on seven farms. Using the data a nutrient input/output balance was constructed for each farm. This was compared with the NBM estimate of the farm nutrient balance. The results showed good agreement between the measured balance and the NBM estimate particularly for the pig and poultry farms. However, the validation emphasised the inherent risks associated with NBMs. The average values used for feed intake and production parameters in the NEMs may result in the under or over estimate of actual nutrient balances on individual farms where these variables are substantially different. On the grassland farms there was a poor correlation between the input/output estimate and the NBM. This possibly results from the omission of the soil's contribution to the nutrient balance. However, the results indicate that the NBMs developed are a potentially useful tool for estimating nutrient balances. They also will serve to highlight the significant fraction of the nutrient inputs into farming systems that are retained on the farm. The potential of the NBM as a means of estimating the nutrient composition of farm wastes was evaluated on two farms. Feed intake and composition, animal production, slurry production was monitored during the indoor winter feeding period. Slurry samples were taken for analysis. The appropriates NBMs were used to estimate the nutrient balance for each farm. The nutrient content of the slurry produced was calculated. There was a good agreement between the NBM estimate and the measured values. This preliminary evaluation suggests that the NBM has a potential to provide the farmer with a simple means of estimating the nutrient value of his slurry.

Comparação de Proteínas: alimentação das aves I

Beginning an experiment on protein comparisons, at the Poultry and Rabbitry Departament of the Esc. Sup. de Agricultura "Luiz de Queiroz", University of S. Paulo, four groups of growing chicks were submitted during 40 days to the following rations: basal part - 50 corn meal and 30 wheat bran, variable part - R1 - 10 tankage and 10 peanut meal, R2 - 10 tankage and 10 cottonseed meal, R3 - 7 peanut meal, 7 cocoanut meal and 7 cottonseed meal, R4 - 5 tankage, 5 peanut, 5 cocoanut and 5 cottenseed meal, R2 and R3 gave results which may be considered as equal and inferior than those obtained with the others, R4 being the best one. The statistical analises showed no significant differences.

Raça de galinhas "piracicaba" I: hereditariedade dos caracteres pescoço pelado e plumagem preta

The characters naked neck and black plumage proved to be due to single genes in a group of chicks growing at the Poultry Department of "Luiz de Queiroz" School of Agriculture, Piracicaba, Brasil. The two characters segregate independently and the animals with known genetical constitution will be used in the formation of a local breed.

Comparação das raças Rhode Island Red, Light Sussex e seu mestiço: ovos, pintos e frangos

The breeds Light Sussex, Rhode Island Red and the hibrid Light Sussex x Rhode Island Red, from the Poultry Department of "Luiz de Queiroz" School of Agriculture, at Piracicaba, S. Paulo, were studied in this paper, Tre authors, analysing eggs, pullets and chick growing arrived to the following conclusion: a) eggs of the Light Sussex breed were haevier; b) the Light Sussex breed was early maturing; c) the cross studied did not show hibrid vigor.

A influência da alimentação verde na postura

A test was conducted at Poultry Department of "Luiz de Queiroz" School of Agriculture to prove the effect of green feed on egg production. One hundred Rhode Island Red hens at plain laying period were divided in ten pens. The lot A was constituted of pens 1 to 5 and the lot B of pens 6 to 10. During 16 days the pens 1 to 5 did not receive green feed and the pens 6 to 10 received it with abundance. After and for a period of 30 days the situation was inverted. The analysis were made considering, a) the production of all chickens and b) discarding the chickens with irregular laying. In both cases the results were statistically insignificant, proving that green feed did not improve egg production.

Raça de galinhas "piracicaba": II. "Pedigree" das aves puras para os caracteres pescoço pelado e plumagem preta

The pedigree of chickens homozygous for black plumage and naked and now obtained in the Poultry Department of the "Luiz de Queiroz" School of Agriculture, was traced in this paper. The animals will be used in the formation of the new local breed called "Piracicaba PPPP", (Pescoço Pelado Preta de Piracicaba), which we propose to start with selection of others morphological characters and mainly the economical ones: egg laying, early maturing and soft-meated chickens.

Raça em formação de galinhas de plumagem azul e ovos azuis

This paper deals with the inheritance of black, blue and blue-splashed plumage in poultry. The material analysed had its origin in the State of Goias, Brazil and the genetical data seems to indicate the interaction of a single pair of genes as in the Andalusian fowls and other blue breeds. The dominant gene for blue egg is also present in the material and selection is now being directed to isolate a breed with blue plumage and blue eggs, named "Tudo Azul", what in Portuguese means all blue (plumage and eggs) and corresponds, in braziliian slang, to the expression "O. K." used in the United States. The commercial possibility of the chickens, as judging by its, laying capacity, is emphasized.

O cereal de Adlay: estudo de seu valor agrícola e nutricional para aves

Both experiments confirm Job's tears are inadequate as poultry feed due the low growing and high mortality shown on the groups receiving Job's tears meal. Considerations are done by the authors about Coix crops, that do not seem economical on the general condition of the country.

Flutuação de Diptera em granja avícola, Pelotas, Rio Grande do Sul, Brasil

In order to investigate the population fluctuation of Diptera in a poultry house in Pelotas, Rio Grande do Sul, Brazil, six collection methods were utilized: 1 (0 to 7 day-old feces from chickens), 2 (7 to 14 day-old feces), 3 (14 to 21 day-old feces), 4 (0 to 21 day-old feces), 5 (accumulated feces) and 6 (tube trap). Analyses of polynomial regression were accomplished independent of the collection method. The survey was conducted from August 1998 to July 1999 in chicken houses at the Conjunto Agrotécnico Visconde da Graça. A total of 28,720 Diptera were collected, including the following species: Coproica sp. and Telomerina flavipes (Meigen, 1830) (15,640); Drosophila repleta Wollaston, 1858 (9,229); Dohrniphora cornuta (Bigot, 1857) (2,539); Ischiolepta scabricula (Haliday, 1833) (544); Lestodiplosis sp. (320); Muscina stabulans (Fallen, 1817) (159); Musca domestica L., 1758 (143); Drosophila melanogaster Meigen, 1830 (95); Telmatoscopus albipunctatus Williston, 1893 (21); Rhegmoclema sp. (14); Fannia canicularis (L., 1761) (7); Stomoxys calcitrans (L., 1758) (2); and unidentified species of Psychodidae (6) and Muscidae (1). The greatest number of species occurred in October, November and December and the fewest in August, September and April. The greatest abundance of Diptera was recorded in October (9,092), while the lowest index of capture was noted in April (658). The population fluctuation was estimated for Coproica sp. and T. flavipes, D. repleta, D. cornuta, I. scabricula and Lestodiplosis sp.

Ixodidas brasileiros e de alguns paizes limitrophes

The knowledge of the Ixodidae becomes every day, more and more important owing to the fact of the increasing number of diseases of man and animals they can transmit. In Brasil besides transmitting treponemosis, piroplasmosis and anaplasmosis to several domestic animals, the ticks are also responsible fo the transmission of the brazilian rocky mountain spotted fever (A. cajennense and Amblyomma striatum) and they can also harbour the virus of the yellow fever and even to transmit it in laboratory experiments (A. cajennense, O. rostratus). The Brazilian fauna of ticks is a small one and has no more than 45 well-established species belonging to the genus Argas, Ornithodoros, Ixodes, Haemaphysalis, Rhipicephalus, Boophilus, Amblyomma and Spaelaeorhynchus. The genus Amblyomma is the best represented one, with 67% of all species of ticks known in Brazil. One of the most important species in the Amblyomma cajennense owing to its abundance and its wide parasitism in many vertebrates: reptiles, birds and mammals, incluing man, who is much attacked by the larva, the nymph and the adult of this species. The other ticks who attack the man are the Amblyomma brasiliense (the pecari tick), in the forests, and the Ornithodoros, especially the species. O. rostratus and brasiliensis. Other species can bite the man, but only occasionally, like Amblyomma fossum, striatum, oblongogutatum etc. Argas persicus, Rhipicephalus sanguineus and Boophilus are very important species not only as parasites but specially because they transmit several diseases to animals. Some of the ticks of the brazilian wild animals are now also parasites of the domestic ones and vice-versa. Arga persicus var. dissimilis is very common among the poultry and transmits the Treponema anserinum (gallinarum). Boophilus microplus is very abundant on our domestic and wild ruminants (Bos, Cervus, Mazama etc.) and can also ben found on horse, dogs, Felis onca, Felis concolor etc., and it transmits to cattle piroplasmosis and anaplasmosis. Rhipicephalus sanguineus (an introduced species) is now very common on the dog, over all the country. The author recommend to give popular names to some brazilian ticks in order to make them more acquainted with the non scientific people. The author gives a classification of the superfamilia Ixoidoidea and keys to the determination of the different species of brazilian ticks. He creates a new family of Nuttallielidae to the so interesting tick, described by Bedford with the name of Nuttaliella namaqua in South Africa, a new variety of Argas persicus, the Argas persicus var. dissimilis nov. var. owing to the differences on the segment and on the size and morphology of the peritrema. He describes also the female of Amblyomma fuscum Nn. A great part of the author's work deals with the biology, life conditions and parasitism of many of the brazilian ticks in accordance with his personal and from other author's researches, especially in reference to Argas persicus, Ornithodoros rostratus, O. brasiliensis, Boophilus microplus, Rhipicephalus sanguineus, Amblyomma cajennense, A. pseudoconcolor, A. auriculare, A. rotundatum (= A. agamum) etc. The author gives a detailed report upon the parthenogenesis of A. rotundatum (A. agamum) that he first described in 1912 and gives also many references to other species of brazilian ticks, to teratological forms etc. He also gives a detailed report of the geographical distribution of brazilian ticks and of the peculiar conditions of its parasitism. The last part of this article deals with references to the species of ticks of some of the South American Republics namely Argentina, Bolivia, Colombia, Paraguay and Venezuela. Amblyomma testudinis Conil, A. neumanni Ribaga 1902 (= A. furcula Dõnitz 1909) and A. parvitarsum Nn. 1899 (= A. altiplanum Dios 1917), are found only in Argentina. It is given a special bibliography dealing with the brazilian ticks and four text figures and one plate.
