Clinical and parasitological evaluation of dogs naturally infected by Leishmania (Leishmania) chagasi submitted to treatment with meglumine antimoniate and allopurinol

Aiming to assess the efficacy of the treatment, to verify the occurrence of possible disease relapses and to search for the presence of parasites after the treatment, seven dogs naturally infected by Leishmania sp., were submitted to a treatment with meglumine antimoniate and allopurinol. For this, lymph node and bone marrow aspiration biopsies were carried out at seven moments. After the end of the six-month observation period all dogs were submitted to euthanasia. Then, spleen and liver “imprints” and in vitro cultures were carried out to search for amastigote forms of the parasite. All animals presented remission of the symptoms and during all the observation period no dog presented relapse of the disease, although amastigote forms of the parasite were observed in two of the animals at the end of the experiment. Thus, it was possible to conclude that the treatment promotes clinical healing but it does not eliminate the parasites completely.

Clinical and radiographic evaluation of surgical treatment of zygomatic fractures using 1.5 mm miniplates system

Fractures of the zygomaticomaxillary complex are among the most common face traumas. Based upon the complexity and great variety of reported diagnoses and treatments, the proposal of this study was to evaluate, clinically and radiographically, unilateral zygomatic fractures treated through internal rigid fixation with miniplates and screws of 1.5 mm. Material and Method: 15 patients with unilateral fractures of the zygomaticomaxillary complex were analyzed, and compared with 15 patients without fractures so that a comparative analysis of the area and the perimeter of the orbital cavities could be made, as well as the distance from the nasal point to the zygomatic prominence between both groups. Results: In the radiographic analysis, the both groups presented similarity in the perimeter and in the area of the orbital cavities. Concerning the distance from the nasal point to the zygomatic prominence, only the operated group showed a significant difference between the sides, even though clinically the observation of the asymmetry had been absent or discreet. Conclusions: The treatment of unilateral fractures of the zygomaticomaxillary complex with the use of plates and screws of the 1.5 mm system proved to be effective, showing good esthetic results and low complication rates.

Posicionamento por ponto de alta precisão utilizando o GPS: Uma solução para a geodinâmica

Point positioning from GPS data can provide precision varying from 100 meters to a few millimeters at the level of 95% probability. To reach the best level of accuracy, users need proper equipment and software, as well as access capability to GPS products available at the International GPS Geodynamics Service. In this paper, the theory related to point positioning using GPS is presented as well as the results of an experiment conducted using data from the Brazilian Active Control System. The results show repeatability better than 5mm and 10mm for the N and E baseline components respectively, and 6mm + 4ppb (parts per billion) for the vertical. Comparison with SIRGAS campaign showed results at the same level of uncertainty as that of the stations used to tie the SIRGAS frame to ITRF94. Therefore, precise point positioning is a powerful tool to be used in applications requiring high level of precision, such as Geodynamics.

Algumas metodologias de avaliação para pavimentos de baixo volume de trafego

This work has as objective, show and compares some of several evaluation methods of pavements, based in the rules and researches realized by another authors, with focus on low traffic volume pavements, which are generally more economic flexible pavements subjected to low loads. Were addressed structure evaluation methods and superficial evaluation methods applied to that kind of pavement, exposing of clearly the procedures to be performed, the advantages and disadvantages, as well the results obtained in the execution of each one of these. This theme was chosen by the widespread use of this type of pavement in the road network of the country and the fact that there is no still a culture of the practical of evaluation nor technical knowledge on the part of municipal governments that are usually responsible for these roads. This study also aims to guide the process of maintenance preventive or recuperative, as they are often made improvements that do not actually solve the real problem of the roads
