Hipotireoidismo em cães: aspectos gerais

Hypothyroidism is a common endocrine disorder in dogs caused by insufficient production and secretion of thyroid hormones. Most affected dogs have primary hypothyroidism that results from lymphocytic thyroiditis, idiopathic thyroid atrophy, or more rarely, neoplastic destruction. Secondary hypothyroidism resulting from inadequate secretion of thyrotropin (thyroid-stimulating hormone –TSH) from the pituitary gland is less commonly recognized. Tertiary hypothyroidism resulting from a deficiency of hypothalamic thyrotropin-releasing hormone (TRH) has not been documented in dogs. The diagnosis of hypothyroidism in dogs is made on the basis of clinical findings, results of routine laboratory and thyroid gland function tests and response to thyroid hormone replacement. Unfortunately, these tests have high sensitivity, but low specificity, for use in the diagnosis of hypothyroidism. Thyroid hormone supplementation is indicated for the treatment of confirmed hypothyroidism and for the diagnoses of the disease through clinical response to trial therapy

Análise dos procedimentos metodológicos de dimensionamento e execução de parede diafragma

The present paper conducts an analysis of all steps for the construction of diaphragm walls, from obtaining the soil parameters until its execution. Construction stages of diaphragm wall are detailed. The paper presents a detailed analysis of the main available calculation methods to obtain the soil parameters and the design of the diaphragm wall. A case history extensively documented in previous research and present in international symposiums was chosen for an analysis of construction process and excavation’s instrumentations, as well as emphasizing the importance of temporary works and construction sequence for deep excavation with cast in-situ diaphragm walls. In general, it is possible to conclude the main difficulty and uncertainty of the dimensioning are obtaining the soil parameter for diaphragm wall design. And, it is also possible to conclude the monitoring and execution control are paramount to the success of the diaphragm wall construction

Aparelho expansor Haas com molas digitais para correção da mordida cruzada anterior e posterior

As mordidas cruzadas anteriores e posteriores podem ser tratadas desde as dentaduras decídua e mista. Embora a literatura descreva diversas técnicas para a correção individualizada desses problemas, o tratamento de pacientes com as duas alterações é pouco documentado. O presente artigo relata o tratamento desses problemas com o expansor tipo Haas associado a molas digitais. Essa alternativa apresenta boa previsibilidade, fácil confecção e instalação, e ótima eficiência.

Implantes curtos em região posterior da mandíbula

The rehabilitation of edentulous areas with osseointegrated dental implants is a well-documented, predictable procedure in the literature, with high success rates. However, the lack of bone at the recipient bed or proximity to anatomic structures limits the rehabilitation procedure especially at the posterior mandible. Thus, short implants are an alternative treatment for such cases of severe bone resorption. The purpose of this study was to review the success rate of short implants, especially those based in the posterior mandible and to show a clinical case. A literature review was made on electronic databases PubMed and Bireme with articles published between the years 2005 to 2012, using the keywords "short dental implants". It was concluded that the success rates of short implants are similar to those presented by conventional implants but still related to their geometry and surface treatment. Also, short implants can be considered as a viable alternative for the rehabilitation of severely resorbed jaws. However, many authors consider that more research is necessary when a short implant is compared to a long dental implant.

Rehabilitacion oral sobre implantes instalados por medio de la tecnica sin colgajo (flapless) y carga inmediata

The oral rehabilitation with osseointegrated implants is a well-documented treatment with high rate of success. Nevertheless, demands related to treatment time and surgical technique began to appear. In this context, the procedure of immediate loading in which the dental prosthesis is placed right after implant surgery has become a constant practice. Although immediate loading has been an important advance, minimally invasive procedures, such as implant placement without raising a mucoperiosteal flap (flapless) are increasingly being performed. Association of immediate loading with the flapless technique improves acceptance by patients and professionals, because no suturing is required. Moreover, it reduces swelling, bleeding during and after surgery, postoperative pain, surgery time, discomfort and hematoma, as well as the need for postoperative medication. These characteristics ease the stages of rehabilitation soon after implant placement, cooperating with prosthodontist's work. Thus, the proposal of this study is to present a clinical case of oral rehabilitation with osseointegrated implants and fixed prosthesis in both arches, in which the flapless technique was applied, followed by immediate loading. It will discuss the diagnosis, prosthetic planning, surgical/prosthodontic procedures and follow-up for 20 months.
