Diagnóstico dos riscos e impactos ambientais da suinocultura no Ribeirão dos Pinheirinhos, município de Torrinha, (SP)

The porcine activity is characterized by its great pollution capacity, generally produce loads of waste that usually are released in superficial water or soil without concern for the consequences to the environment. With this in mind, this study aimed to adjust the porcine production to the protection of water resources, in particular, Ribeirão dos Pinheirinhos in the town of Torrinha (SP), through inventory and diagnosis of the environmental impacts already present and environmental hazards linked to the activity in question. To achieve the proposed objectives, the productions of porcine on the studied area were raised and georeferenced, viewed and analyzed according to the technical and scientific literature. The production visited showed to be at odds with the protection of water resources due to lack of technical criteria in the development of treatment systems and waste handling, indiscriminate use of effluent and waste in the fertilization of crops and the lack of knowledge of producers on the influence of porcine waste into the environment. Based on these results, were set guidelines for action in the environmental awareness of farmers, to stimulate voluntary and conscious initiatives of environmental conservation in the direction of settlement of the activity.

Insuficiência renal crônica em cães

The kidneys, for his anatomical and functional characteristics, are sensitive to affections that take the liberation of renal toxins or the blood supply, causing irreversible injuries to his renoparenchymal tissue that is substituted by fibrous tissue. Even after the resolution of the basic cause, there will be the loss of a significant number of his functional unity, renal adaptations will take place in the attempt of maintaining the renal function. These adaptations produce additional injuries, perpetuating to loss of renoparenchymal tissue and the reduction of the renal function. The renal insufficiency (IR) takes place after the loss of 3/4 of the number of his functional unities. Before the progression to the phase of IR, the animal shows up practically without symptoms, but for the gradual increase of the urinary and of the ingestion of water. The reduction of the degree of renal function leads to alterations system compensatory for the accumulation of substances that would suffer renal excretion. The progression of IR leads to the phase of the syndrome urêmica. In this phase the animal presents innumerable clinical signs that can take it to the death. The treatment is symptomatic and dietetic, but depending on the phase not much efficient. Because of being progressive and insidious, the IRC demands the preparation of campaigns and programs of explanation for the veterinary doctors who aim for the consciousness and/or sensibility of the owners to carry out periodic examinations of selection that precociously detect the renal dysfunction. The diagnosis in the beginning IR enables the efficiency of the treatment in stop or slowing his progression, extending the time and quality of life of the patient

Programação linear no planejamento do tratamento de câncer por radiocirurgia

Medical Physics has been reaching an important role among several lines in Science, providing means for the improvement of several theories and procedures. Currently, its main application is related with the use of ionizing radiations, specially, in treatment procedures such as Radiotherapy. Radiosurgery is a Radiotherapy technique which consists in administering a single tumoricidal dose of radiation exclusively to the tumorous lesion. It becomes then an interesting alternative to surgical treatment, mainly in cerebral metastases, which are the most frequent cerebral tumors in the central nervous system. The radio neurosurgical team works out a planning for the Radiosurgery treatment, aiming for obtaining an appropriate ideal treatment for each case. For the working out of this treatment planning, Computed Tomography images of the region to be treated are obtained, digitalized and later, fused with nuclear magnetic resonance images. Through these images, critical structures, organs at risk and lesions are localized. After this, calculations are made to determine three-dimensional positions of isocenters, isodose curves, prescribed dose, collimators sizes, position, numbers and respective weight of isocentric conformal fields, and others. The treatment planning is commonly based in desired levels of dose for specific types of tumors and organs at risk concerning the irradiated region. Theses levels of dose are chosen in a way that a high probability of cure may be achieved and meanwhile, that the probability of complications, in whichever organ at risk, may be minimal. Thus, many researches have been carried out, showing that mathematical techniques may help to obtain an optimal planning for the treatment of cerebral metastases. Among the methods of optimization in the study...(Complete abstract click electronic access below)

Diagnóstico ambiental do Córrego Bandeirantes, município de Rio Claro, SP: parâmetros biológicos e metais-traço

This study was conducted to verify water quality and environmental impacts related to the occupation of the watershed of the Bandeirantes stream, located in Rio Claro, SP. The intention is to propose measures to enable the mitigation of negative impacts, and boosting the recovery and maintenance of the quality of water resources, preventing its complete degradation. Water analysis were performed at three different points, east, crossing the Ring Road (dirt road) and near the confluence with the Ribeirão Claro. The results indicated significant degradation of water, especially after the crossing, where it witnessed the accumulation of solid waste and easy access to the stream, both for animals as for people, due to limited riparian it. Another impact was observed the current construction of the Forum of Rio Claro in the right side of the stream studied, causing change in the landscape, change the flow properties and removal of existing vegetation at the site of work, defined as an environmentally protected area, as determined by existing law. Measures such as: restoration of riparian zones, effluent treatment, planned urban growth and environmental education of the population, would be essential to mitigate the environmental impacts of watershed Bandeirantes stream

Percepção dos portadores de hanseníase acerca do auto cuidado

This study aimed at evaluating the perception of leprosy patients, the disease, with regard to its concept and self-care practice, as well as their knowledge concerning drug therapy. Fifteen patients participated in the study, of whom 11 were classified as multibacillary and 04 as paucibacillary. Semi-structure interviews containing six guiding questions were used for data collection, and the Collective Subject Discourse (CSD) was utilized as a theoretical framework. Analysis was performed based on the Theory of Complexity. It showed that patients suffer pain, a fact that is reflected on the need to change habits and prevent disability. It also showed that patients have doubts and feel insecure about treatment and prognosis, and that they are also the target of social prejudice even thought the term leprosy has been replaced by Hansen‟s disease. As regards self-care, the subjects showed lack of autonomy, limitations and subjection to instructions from health care professionals, who, according to the discourse that emerged, are mostly responsible for transmitting the knowledge concerning self-care practice. This fact can be explained by evidence of self-knowledge deficit by the the subjects. Concerning polychemotherapy treatment, which is recommended by the Ministry of Health, it was observed that the knowledge concerning its action and adverse effects is precarious. This information is provided during consultation; however, CSD showed that the subjects do not apprehend it. Therefore, health care professionals must instruct their clients not only as regards conventional treatment practices, but they must also help them to know themselves and to improve their critical judgment so that they can choose the best form of living after being diagnosed with the disease, thus guiding self-care by taking such choice into account

Pediculose na escola - uma oportunidade para aprender e ensinar

O piolho de cabeça atualmente é um problema mundial e não está relacionado à pobreza, falta de higiene, desleixo. Sua prevalência é alta na idade escolar de três a doze anos de idade. Quando uma criança o adquire tem um sentimento de vergonha, deixa de ir à escola e raramente é encaminhada para cuidados médicos. Geralmente para o controle, as famílias utilizam substâncias tóxicas, inseticidas domiciliares, produtos inflamáveis e ervas na cabeça das crianças. E ainda, acreditam que o piolho pode ser transmissor de doenças. Há uma falta de informação e neste caso, a educação se faz necessária. O objetivo deste trabalho foi elaborar um instrumento de avaliação de professores das séries iniciais do ensino fundamental I, da rede pública de ensino, da cidade de Botucatu – SP, relacionado à pediculose. Esta análise ocorreu através de um questionário constituído de 10 perguntas abertas e 14 fechadas (concordo e discordo) com abordagem educacional (ensino sobre piolho - conhecimento, atitude e prática) e com uma abordagem didática sobre biologia, diagnóstico, prevenção, tratamento, transmissão sobre o piolho de cabeça. Este trabalho foi realizado em 9 escolas da rede pública do ensino fundamental I com 108 professores.Todos os dados foram tabulados no programa Microsoft Excel 2000 versões 7.0 e as análises foram realizadas com base na estatística descritiva, não – paramétrica, segundo o método estatístico que consiste em técnica de análise de variância não paramétrica para o modelo com um fator – Teste de Kruskal-Wallis e por tabelas de freqüência. A análise estatística dos dados obtidos dos questionários mostrou como resultados mais pertinentes a posição de 100% dos professores que nunca deixam de falar sobre piolho em sala de aula, nunca proíbem o aluno...

Treinamento aeróbio na prevenção de alterações cardíacas decorrentes da obesidade em ratos (Rattus Norvegicus Albinus, Wistar)

A obesidade é um problema de saúde pública mundial e está fortemente associada à doença cardíaca isquêmica, aterosclerose, hipertensão arterial, entre outros problemas cardiovasculares. Na atualidade, o tratamento sugerido para as doenças cardiovasculares, comumente decorrentes da obesidade, consiste na diminuição da ingestão de gordura aliada à atividade física. Contudo, pouco se sabe quanto aos protocolos de treinamento mais adequados para a prevenção ou tratamento dessas doenças. O presente estudo objetivou analisar os efeitos do exercício físico na intensidade de 80% do limiar anaeróbio (LAn) sobre os aspectos bioquímicos cardíacos de ratos obesos. Para a indução da obesidade, os animais, a partir dos 90 dias de idade, foram mantidos com dieta hiperlipídica/hipercalórica (35% de gordura animal/vegetal) e os animais controles, mantidos com dieta balanceada (AIN-93M). Todos os animais pertencentes ao grupo treinado foram submetidos a testes de lactato mínimo para a identificação do limiar anaeróbio (LAn) durante exercício de natação, treinando desde os 28 dias de idade até aos 90 dias em intensidade equivalente a 80% do LAn 1 h/dia, 5 dias/semana. Depois dos 90 dias uma parte dos animais treinados interrompeu o treinamento ficando em observação até o final do experimento (150 dias de idade). Os demais animais permaneceram sedentários ao longo de todo o experimento. Foram analisados: peso corporal, tolerância à glicose e à insulina (TTGo e TTI), perfil lipídico sérico (colesterol total, triglicerídeos, AGL e HDL), concentrações séricas de glicose e insulina e alíquotas do ventrículo esquerdo foram retiradas para análise das concentrações de triglicerídeos, glicogênio, proteína/DNA e atividade lipogênica. Os animais tratados com dieta hiperlipídica tiveram aumento significativo no peso corporal, intolerância à glicose e resistência à insulina e o treinamento físico neutralizou tais...

Análise dosimétrica de aplicadores de Betaterapia

Betatherapy is a special medical technique using a radioactive source of strontium-90 for the treatment of superficial lesions, especially in dermatology and ophthalmology. Strontium-90 sources emit β radiation, which possesses high ionization power, but a very short distance propagation into matter. This work presents a method of dosimetric analysis of betatherapy using strontium- 90-based instrumentation, commonly used against superficial diseases, such as keloid and pterygium, aiming the description of the dosimetry analysis procedures, which can be easily implemented on tradiotherapy services that offers the betatherapy treatment. IBF-MEDIX radiographic films (conventional films) were exposed to betatherapy applicators during different time intervals according to the activity of the source, and afterwards the optical densities (O. D.) of the radiographic images were measured using an optical densitometer MACBETH. Therefore, the parameters used to make the dosimetric analysis in betatherapy were standardized, as the exposure time depended on the geometry and size of the source, providing an efficient and fast method of dosimetric analysis of the betatherapy equipment of the services, the majority of which do not have the scientific structure to perform this study

Avaliação dos aspectos dosimétricos no tratamento de câncer de tireóide com Iodo-131

The 131I (radioactive iodine) is one of the most used radionuclides in nuclear medicine for diagnosis and treatment. The present study evaluates the dosimetric aspects related to radioiodine therapy after thyroidectomy in patients with thyroid cancer. The samples were studied with 50 patients undergoing treatment, by assessing the exposures of workers (nursing assistants, staff hygiene, medical and physical), the general public (accompanying and family members) and on the environment. To evaluate the workers, was made a survey of the environmental conditions of the room radioiodine and routines adopted by them during the treatment period. Estimating the dose equivalent per month for each employee, we observed that the maximum levels obtained for nursing assistants, the team of hygiene, medical and physicians were considered low in relation to the extent permitted by law. In order to assess the public, some situations have been suggested for the calculation of equivalent doses in which it was possible to verify the fundamental importance of isolating the patient in the 2 days first. Regarding the environment, the radioactive waste generated by patient had volume of 1.0 m3 and activity estimated at 0.91 mCi, taking a decay time for eliminating them about 75 days to reach the allowable value of 2 μCi / kg system of collecting garbage. Therefore, all radioactive waste removed from the patient's room should be sent to the warehouse for temporary storage of radioactive waste, located away from normal work areas

Efeito do ácido tânico purificado (tanino) sobre o crescimento in vitro de isolados de Pythium insidiosum

Pythiosis is caused by the oomycetous Pythium insidiosum and affect domestic and wild animals and man. The presence of water and vegetal material is fundamental for its life cycle in nature. The biflagellate zoospore are the infective form of this pathogen. The lesions are generally of granulomatous aspect, which frequently may be contaminated by secondary bacterial infection in skin and subcutaneous tissue. Dissemination to systemic tissues may also occur and it may be due to the spread of the pathogen from cutaneous lesions, as well as a primary source of infection. Clinical signs depend on the affected tissue. Diagnosis of pythiosis is based on the clinical manifestations, histopathological sections and culture of the pathogen. Serological tests may also be employed and more recently molecular biology has been introduced as a sensitive, specific and a rapid method for conclusive diagnosis. Treatment is often difficult and extensive surgery procedures are required, however, depending on the anatomic region and size of the lesion, such procedure is unfeasible and relapses are frequent. Due to the climate changes, which has contributed to increase the incidence of pythiosis, it is necessary the search for new therapeutic protocols

Atualizações sobre o uso de óleo de peixe no tratamento de cardiopatia canina

There are cardiopathies that acometem the dogs, being able this being congenital or acquired and lately have grown the number of cases due to the increase of the life expectancy of these animals becoming each time more necessary prevention methods. In recent years innumerable research is being carried through to understand the influence of the fish oil in the cardiopathies. The fish oil ingestion, Omega 3, has shown beneficial effect in the prevention of cardiovascular illnesses in such a way in the men as in the animals. Such effect this related to the presence of acid greasy polyunsaturateds n-3, mainly acid the eicosapentaenóico (EPA) and acid the docosahexaenóico (DHA). These substances can be found in foods as marine cold water fish (salmon, tuna, sardine and Trout), hemp seeds and soy. The present study, therefore, it has as objective to carry through an update on the use of the fish oil in the treatment of cardiopathies in dogs

Métodos diagnóstico de Hiperadrenocorticismo canina

The Hyperadrenocorticism is a disease that occur in dogs between mead to old age, is associated with the higher level of glucocorticoid that result in a corporal reaction. To make a diagnostic of this disease is necessary have a good history and physical examination, the principals complains of the proprietary are polyuria, polydipsia and polyphagia, in some times abdominal enlargement and lethargy. In the physical examination is observed this abdominal enlargement, hepatomegaly, alopecia, in some cases pyoderma and difficult respiratory. From this documents is possible determinate the differential diagnostics and with the tests find the diagnostic of the disease that the animal have. The base methods are hemogram, biochemical, urinalysis, radiographs and ultrasonography it’s possible do tomography and magnetic resonance too. There are confirmation methods too, they are very important, because the others not have documents necessary for the final diagnostic. Those are Urine cortisol to creatinine ratio, dexamethasone suppression test with high dose or low dose and ACTH stimulation test. Despite those tests have high sensibility and specificity, they can result in false positive or false negative, this is one of the causes to do the base methods and together make the veterinary doctor find the solution of the diagnostic and do the adequate treatment

Pênfigo Foliáceo em cães

Pemphigus complex in animals is considered rare, but not so when compared with the occurrence of other autoimmune diseases. Pemphigus Foliaceus in dogs is the most common varieties of pemphigus and is characterized clinically by intraepidermal pustules, starting on the face and ears, pads, groin, and may become multifocal or generalized in six months. As the pustules are very fragile, the lesions usually found are secondary, which may range from dry to collarettes epidermal crusting, and nasal depigmentation. The diagnosis is difficult because presents sintomatology similar to other diseases and laboratory diagnosis more precise through the histopathological examination of pustules integrate (biopsy), which are rarely found. The treatment, although of the individual treatment regimen, is based on treating opportunistic diseases and immunosuppressing the animal in order to decrease the production of autoantibodies. The drugs of choice depend on the clinical presentation, however is usually oral prednisone and azathioprine in the dog and combined immunosuppressive therapy. Should make use daily until the disease is inactive and gradually decrease the dose until have the minimum effective dose, preferably on alternate days for the remission of the disease. Prognosis of pemphigus varies according to disease stage and treatment established. Pemphigus foliaceus is less serious nonetheless might be fatal without treatment
