Dar voz às vozes das crianças na construção da prática pedagógica

O presente artigo pretende apresentar a problemática que se destacou nas Práticas Profissionais Supervisionadas realizadas no decorrer do Mestrado em Educação Pré-Escolar (creche e de jardim de infância) no ano letivo 2012-2013. As duas práticas foram realizadas em contextos bastante distintos, sendo que esta diferença – com alguns pontos convergentes - foi um dos principais motes para nos apercebêssemos do aspeto educacional que nomeia este trabalho e sobre o qual iremos refletir, recorrendo às evidências que recolhemos ao longo do percurso educativo percorrido. Este texto abordará os aspetos em que nos baseámos durante o decorrer de todo o processo educativo, para construir a ação pedagógica: a concentração nas vozes das crianças e a forma como um Educador se deve posicionar para conseguir ouvir, efetivamente, os grupos com que trabalha

Reactive Seizures Due to Hyperlipidemia in a Maltese Dog

Background: Primary hyperlipidemia is a condition that affects some specific breeds. It has been previously described in Miniature Shnauzer, Beagles, Shetland Shepdog and West Highland White Terrier. There are no reports of primary hyperlipidemia in Maltese dogs. It is a hereditary disorder of lipoprotein metabolism. The etiology is unknown and may be related to a genetic problem in lipoprotein lipase or to the absence of apaprotein CII. Clinical signs include spontaneous arterosclerosis, retinal lipemia, cutaneous xanthomas, abdominal pain, lethargy, vomiting and / or diarrhea. Neurological manifestations such as seizures and behavioral changes may also occur. The aim of this report is to describe a case of reactive seizures due to hyperlipidemia in a dog.Case: A 5-year-old male Maltese dog was admitted with a history of seizures. Hypertension and abdominal distension with large amounts of intestinal gases were found in general physical examination. Neurological examination revealed impaired nasal septum sensory perception, which was slightly bilaterally reduced, and pain on cervical palpation and in the brachial plexus region. Based on history and clinical examination, it was possible to locate the lesion in the thalamocortical region and to suspect idiopathic epilepsy, reactive seizures, and symptomatic epilepsy due to meningoencephalitis of unknown origin. The diagnosis of primary hyperlipidemia was made by exclusion with the aid of laboratory tests and ultrasound. After the establishment of a fat restriction diet, bezafibrate, phenobarbital, and omega-3 supplementation, the animal improved significantly with the reduction of epileptic seizures.Discussion: The initial clinical suspicion was hyperadrenocorticism as the primary cause of hyperlipidemia. This suspicion was based on the presence of polyphagia, polydipsia, polyuria and abdominal distension, together with laboratory results of thrombocytosis, increased ALT and AF, and hyposenuria; but ultrasound images and ACTH stimulation test ruled out this differential diagnosis. Hypothyroidism was also ruled out since LDL values were normal and the animal was extremely active. Regarding nephrotic syndrome, it was also excluded for some alterations would be present, such as severe proteinuria, cholesterol reduction and hypoalbuminemia. As for diabetes mellitus, it was discarded because of the dog’s young age and due to the absence of suggestive clinical signs. The suspicion of primary hyperlipidemia was based on increased levels of triglycerides, and the presumptive diagnosis was of reactive seizures due to hyperlipidemia. It is essential, when treating hyperlipidemia, to readjust to a low-calorie diet with fat concentration below 8% and protein level above 18%. Generally, these restricted diets are for life. Omega-3 supplementation can be performed to help maintain low levels of triglycerides. Drug therapy is usually carried out with bezafibrate, which is used in human medicine as treatment for hypertriglyceridemia, and has showed good results in the control of hypertriglyceridemia and hypercholesterolemia in dogs with primary and secondary hyperlipidemia. Six months after the beginning of the treatment, the animal no longer presented abdominal distension and pain, cholesterol values and its fractions were controlled, as well as triglycerides. Seizures were also under control. Therefore, hyperlipidemia is an important differential diagnosis in cases of patients presenting seizures, especially when dealing with young animals showing signs of metabolic diseases

Megabacteria (Macrorhabdus ornithogaster) em psitacídeos mantidos em estabelecimentos comerciais do município de Uberaba – MG

A megabacteriose é uma doença que acomete algumas espécies de aves, tendo como agente etiológico Macrorhabdus ornithogaster, um microrganismo Gram positivo de forma bacilar e com características de fungo, sendo classificado como fungo ascomiceto anamórfico. É um agente oportunista que se torna patogênico em casos de imunossupressão, manifestando assim a sua forma clínica, que varia muito de acordo com cada animal, podendo levar o animal ao óbito. Neste contexto, o presente trabalho objetivou avaliar a prevalência de megabacteria em psitacídeos criados em estabelecimentos comerciais do município de Uberaba-MG associado as condições de criação. Para isso, foram colhidas amostras de secreções do ventrículo e pro ventrículo de 71 aves, entre elas Calopsitas (Nymphicus hollandicus) (n=33), Periquitos Australianos (Melopsittacus undulatus) (n=31), Agapornis (Agapornis roseicollis) (n=4) e Catarinas (Bolborhynchus lineola) (n=3) e transferidas para lâminas de vidro. As amostras foram encaminhadas para o Laboratório de Medicina Veterinária Preventiva do Hospital Veterinário de Uberaba, para pesquisa do patógeno. Após coloração das lâminas por Gram pode-se notar a presença do microrganismo em 35,21% das aves analisadas. A prevalência entre as Calopsitas, Periquitos Australianos, Agapornis e Catarinas foi respectivamente de: 42,42% (14/33), 29,03% (9/31), 50% (2/4) e 0% (0/3). Neste contexto, pode-se concluir que a Macrorhabdus ornithogaster é comum entre as aves, principalmente entre as Calopsitas e o manejo incorreto dos animais pode ser a causa da elevada prevalência. Nos estabelecimentos comerciais observaram-se as condições das gaiolas, qualidade dos bebedouros e comedouros, quantidade de fezes na gaiola e número de animais por gaiola inadequados

Genetic evolution of milk yield, udder morphology and behavior in Gir dairy cattle

The objective of this study was to analyze the genetic evolution of milk production, udder morphology, and animal behavior of Gir dairy cattle. Data were obtained on the predicted breeding values for milk yield of 60,226 cows born from 1968 to 2015 and standardized predicted breeding values for udder conformation and milking behavior of 7,635 cows born from 1987 to 2015. The influence of tested bulls on genetic trends was discussed, with special focus on the period after 1993, the year when the predicted breeding values of the first group of tested bulls were released. The traits of interest were 305-d milk yield, fore udder attachment, rear udder height, rear udder width, teat length, teat thickness, ease of milking, and reactivity. Significant genetic evolution was observed for 305-d milk yield, with increasing annual growth observed from 1993, as the number of cows sired by the best proven bulls increased. Before 1993, no genetic evolution was observed for any of the studied traits. From 1993 onward, all traits showed genetic gains, except fore udder attachment. The use of geneticallytested bulls since 1993 has led to important genetic gains in the Brazilian Dairy Gir population. Before the identification of genetically superior bulls began, many traits showed no improvement. Selection for milk yield has modified the conformation traits of the Gir mammary system. The longevity of the mammary glands of high-yield cows may be impaired due to poor fore udder attachment. Regarding behavioral traits, this population has evolved to less-reactive animals that are easier to mil

Uberaba, MG, BrasilBACKGROUND: Trypanosomiasis is a disease caused by Trypanosoma (Dutonella) vivax, a hemoprotozoa that can affect bovines. In South America, the sanguineous form is mechanically transmitted from one mammalian host (ruminant) to another by the bite of a blood-sucking insect or by needles contaminated with infected blood. The negative impact of the parasitosis caused by T. vivax infection on the reproductive activity of male and female ruminants is known to reduce fertility. In males, alterations such as degeneration, diffuse or interlobular inflammatory infiltrate found in ovine and bovine testicles, can affect fertility through decreased sperm quality. This study evaluated the impact of natural infection with T. vivax on Zebu bulls from the Central Station of Artificial Insemination (CSAI) with regard to libido and the negative effects caused by this protozoan on semen quality. METHODS: Blood samples of 44 animals were collected to evaluate the presence of the trypomastigote form of T. vivax in blood smears obtained from hematocrit and buffy coat, and antibody titer IgG anti T. vivax in indirect Immunoflorescence (IFI). Furthermore, data related to libido, ejaculate volume, spermatic concentration, and seminal vigor were recorded for these animals employing the criteria of the CSAI. RESULTS: Nine animals (20.45 %) showed T. vivax trypomastigotes and parasitemia between 0.02 and 0.07, and antibody titers from 1:80 to 1:320 in IFI. Twenty nine negative animals in parasitological tests were not reactive in IFI, and six animals presented the antibodies IgG anti T. vivax in IFI. Data on reproductive activity showed that animals infected with T. vivax have a decreased libido and an increased spermatic volume, whereas other factors related to the reproductive process such as spermatic concentration, motility and spermatic force, were unchanged in infected bulls. CONCLUSIONS: The T. vivax infection in Zebu bulls from CSAI caused patent parasitemia, induced a febrile state, promoted reduction in the libido and increased the ejaculate volume. These conditions together may account to decrease the performance of these animal
