The proposal of this study was to compare a wound healing between conventional suture and vaporization with CO2 laser in rats skin. ln such case 24 rats were utilized, making two longitudinal incisions in dorsum by scalpel. ln the left side incision the wound was sutured with nylon thread. ln the right side incision the wound were close by approach and vaporized with C02 laser, defocusing, 8 watts in continuous mode. The wound healing was followed by clinical photographic taking at the times: immediately after the procedure, 24 hours, 3, 7, 14, and 21 days. The results showed an early delay of reparation in healing vaporized in comparison with the sutured one, however occurred 21 days both repair tissue showed the same clinical characteristic. This results suggested that the C02 laser can be used by eventual substitute of suture.

A clinical investigation was undertaken to find out the prevalence of craniomandibular signs and symptoms in a group of 11 patients with labiopalatal lesions. The number and distribution of occlusal contacts was evaluated through questionnaire, clinical examination and analysis of mounted casts in partially adjustable articulators in the position of maximum inter cuspation. The most frequent signs and symptoms were articular sounds and lateral pterygoid muscle tenderness to palpation followed by restriction of mouth opening and sensation of tiredness. The number of occlusal contacts was small, mean of 5 contacts per patient, and the site was considered as atypical, 62% of them were on inclined plane surfaces , suggesting occlusal instability. The frequency of signs and symptoms was low and they were of a mild character. The most prevailing signs of craniomandibular dysfunction - articular sounds, muscular tenderness to palpation and restriction of mouth opening - was noticed in only one of the patients

Protrusion of the intervertebral disc can cause chronic progressive compression of the spinal cord, and the neurological associated signs vary according to anatomical location, duration and dynamic force of compression. The type II disc disease is not fully understood, and there are many controversies about is clinical significance and best form of treatment. The most important aspect of conservative treatment is rest and physiotherapy associated with mild exercise, and use of corticosteroids to reduce vasogenic edema. The spinal decompression by surgery for removal of disc material from within the medullary canal is the surgical treatment of choice in type I disc disease, but has technical limitations in the type II disc disease. The purpose of this paper is to review the pathophysiology and treatment of chronic intervertebral disc disease and discuss the controversies in medical treatment and the use of some traditional and new surgical techniques.

The urbanization process established in Brazilian society since the middle of last century brought changes in the population habits and customs, which was responsible for the increased of chronic diseases incidence, such as arterial hypertension, for example. Although this is a common disease nowadays, it is still difficult to establish a significant control in subjects with this disease and its consequences. This is apparently due to lack of interest to the correct plan of care developed for the treatment of this disease. The nursing consultation identifies potential problematic situations and the patient needs, setting actions that are complementary to their benefit in order to promote health. The present work aims to observe how the nursing consultation is being used as strategy for patients with arterial hypertension, and to understand the difficulties faced during treatment of these patients. For this purpose, it was performed qualitative and quantitative studies with patients from Centro Saúde Escola (CSE), Unidade Auxiliar, Faculdade de Medicina de Botucatu, UNESP, located in Botucatu, employing as methodology the Discourse of the Collective Subject and descriptive statistical analysis of quantitative results. The vast majority of consultations were held by medical professionals and it was observed that the multidisciplinary work still needs to be recognized and valued by users. The lack of knowledge of some individuals in relation to the potential and importance of the nursing consultation occurs not only for the treatment of arterial hypertension, but for the treatment and monitoring of the individual as a whole. Therefore, it is still necessary to clarify the true essence and necessity of the nursing consultation, since so important tool should be used in its entirely. Moreover, the role of the multidisciplinary team should be more discussed

This work aims to analyze data from a Natural Electric Potential landfill type ditch located in Cordeirópolis (SP). The procedure measures initially involved the assembly and installation of an apparatus cables, sensors and drain geophysical measurements and flow rate of biogas in a ditch later filled by solid waste. Biogas is a product of degradation of organic matter in waste by the action of microorganisms in an anaerobic environment. Its features high methane content in the gas potentially usable as fuel in energy generation systems or steam. The study area is characterized by clayey soil composition change from the diabase sill correlated to the event Serra Geral Formation siltstones overlapping Tatuí with groundwater level site around 50m. The cables were installed vertically in parallel with drain gas manifold, which allowed the collection of data by the technique geophysical logging every 15 days over a period of eight months. For data analysis we used four parameters in the study, the closing time of the ditch, natural electric potential, the flow velocity of biogas and rain. With the tabulated data plots were constructed for each collection day showing values in the range of the cable is in contact with waste (200 cm - 400 cm) and range of the cable in contact with the soil (600 cm - 800 cm). Subsequently graphs were generated with the period of eight months to analyze the data tabulated. A statistical correlation data, which show the influence of rainfall on the production of biogas. The results were satisfactory and demonstrated the feasibility of the research method in studies for the feasibility analysis for the capture of biogas energy

Oncology is presenting an important role in clinical practice as a speciality in recent years in Veterinary Medicine. Mammary gland tumors are detected mainly in old and middleaged bitches that are sexually intact or spayed and the caudal abdominal and inguinal mammary glands are the most affected and they present a percentage up to 75% of malignancy. The majority of dogs with mammary neoplasms are clinically healthy at the time of diagnosis and the tumors can be identified by the owner or a professional during a routine physical examination. Cytological examination of fine needle aspirates can be performed. This procedure is easy and low cost and some criteria that may indicate malignancy are evaluated, however to obtain a definitive diagnosis is performed histopathology of the excised tissue or from biopsy. Regional lymph nodes are the first lymph node to receive lymphatic drainage from the neoplasm. They are at the highest risk of regional metastasis, while the lung is the most common site for distant metastasis. Determining the clinical stage enables the definition of the extension of the tumor. As a consequence, this allows a prognosis to be established and treatment to be planned. The type of therapy to be chosen incites controversy since there are numerous treatment options described, but the surgery is the chosen treatment. However, surgery is not always effective for malignant tumors, and recurrences may occur and in these cases, auxiliary chemotherapy treatments are used. The prognosis for animals that have mammary tumors depends on several factors, such as: size, stage, type of tumor cells and clinical behavior of the tumor, age and medical condition of the animal, and presence of metastasis. Because of this, more detailed studies are needed based on epidemiological surveys in order to provide more informations about risk factors, prevalence and follow-up after treatment of mammary...

The geophysical methods are widely applied in environmental characterization and monitoring studies. The resistivity method, in particular, has a wide area of applications, being effective in studies of solid waste landfills. The present work propose a geophysical monitoring in the Cordeirópolis city controlled landfill and analyze relationships between variation of electrical resistivity parameter, the residence time of the solid waste in landfill, the rainfall in the region and the organic matter biodegradation processes. The study has no monitoring system to control the products generated in the organic matter decomposition found in waste such as sealing blanket or leachate or gas drains. The results shows that the electrical resistivity parameter was effective in monitoring the landfill contamination plume
