Collaboration of ultrasonography in the diagnosis of thyroid gland carcinoma in a dog - case report

The sonographic evaluation of thyroid glands in veterinary medicine presents challenges due to the complexity of the anatomical region, professional experience and type of ultrasonography equipment. The technique is considered a versatile diagnostic method that is noninvasive and has a low cost indicated in different clinical situations. Thyroid carcinoma is a malignant tumor that is often invasive and frequently metastatic to regional lymph nodes and lungs. The prognostic indicators for survival after surgery include tumor size, histological type, mobility and presence or absence of metastasis. The objective of the present report is to demonstrate the importance of ultrasound as a complementary method in the evaluation of thyroid carcinoma in dogs. At the Dr. Halim Atique Veterinary Hospital, an eight-year-old male Pit Bull was examined due to a history of firm painless swelling, approximately six inches in diameter, in the ventral cervical region, for about two months. The sonogram showed a nodular area, with defined and regular margins, and heterogeneous hypoechoic parenchyma, with areas of cavitation and swelling of the thyroid. Histopathology of the nodule was consistent with carcinoma. After thyreoidectomy and hormone replacemet, the patient is in good clinical condition.

A integração da medicina complementar e alternativa em sistemas de saúde convencionais

Complementary and alternative medicine (CAM) is becoming increasingly popular, and despite of the growing demand for these practices, physicians and CAM-providers work separately and there is no sufficient effort in the promotion of an integrative health care. Questions like differences of concepts and language, lack of scientific evidence through randomized clinical trials, no regulation of CAM-providers, products and services, besides the lack of government policies in this scope, turn the process of integration difficult and threaten the quality of delivery of health care. Through the integrative review method, the purpose of this paper is to discuss the issues involved in the integration process of complementary and alternative medicine into the conventional health care systems (guided by principles of biomedicine), addressing benefits and risks, obstacles to integration and models of integration in the discussion topicsl

Aplicação da acupuntura em animais silvestres

This study will focus on one part of Traditional Chinese Medicine (TCM), acupuncture - utilized as therapy method for pathologies treatment in humans and animals - , as well as its main techniques. Acupuncture is one branch of TCM, originated from theoretical and empirical knowledge accumulated by popular medicine. Currently, researches performed in humans and animals have shown the effectiveness of this method as an assistance or alternative in illnesses treatment. Besides that, professionals are not merely looking for orthodox medicine knowledge, but also specializations and improvement over the complementary therapies area. There are diverse studies and researches which were and are being done in veterinary, relating the effectiveness of acupuncture in small and large animals. In comparison, in the wild animals’ area the numbers of studies is smaller. However, it is expected that this number increases over the fact that some of these animals’ species are entering the pet market and also because of the possibility of using these methods for treatment and prevention of diseases on zoo animals or other animals kept in captivity

SPECT (Single photon emission tomography): Gama câmara, reconstrução tomográfica e características funcional

The SPECT (Single Photon Emission Computed Tomography) systems are part of a medical image acquisition technology which has been outstanding, because the resultant images are functional images complementary to those that give anatomic information, such as X-Ray CT, presenting a high diagnostic value. These equipments acquire, in a non-invasive way, images from the interior of the human body through tomographic mapping of radioactive material administered to the patient. The SPECT systems are based on the Gamma Camera detection system, and one of them being set on a rotational gantry is enough to obtain the necessary data for a tomographic image. The images obtained from the SPECT system consist in a group of flat images that describe the radioactive distribution on the patient. The trans-axial cuts are obtained from the tomographic reconstruction techniques. There are analytic and iterative methods to obtain the tomographic reconstruction. The analytic methods are based on the Fourier Cut Theorem (FCT), while the iterative methods search for numeric solutions to solve the equations from the projections. Within the analytic methods, the filtered backprojection (FBP) method maybe is the simplest of all the tomographic reconstruction techniques. This paper's goal is to present the operation of the SPECT system, the Gamma Camera detection system, some tomographic reconstruction techniques and the requisites for the implementation of this system in a Nuclear Medicine service

Acupuntura veterinária em pequenos animais

Acupuncture is one of the oldest forms of treatment, which is based in the grounds of Traditional Chinese Medicine. Despite the ancient history, it’s not completely widespread in Brazil, neither so comprehensive in veterinary medicine as used in humans. The technique of inserting needles into acupuncture points, can also be stimulated by heat, electrical stimulation or implants of metal, is mainly focused on neuromuscular disorders in small animals. The difficulty of comprehension of language and the lack of cientific bases restricted the possible applications of acupuncture. This work will address some of the clinical situations this complementary treatment can act, such as neurological, cardiorespiratory, reproductive, gastrointestinal, immunological, and postoperative intensive care

Green tea extract and its major constituent epigallocatechin-3-gallate inhibit growth and halitosis-related properties of Solobacterium moorei

Background: Solobacterium moorei is a volatile sulfide compound (VSC)-producing Gram-positive anaerobic bacterium that has been associated with halitosis. The aim of this study was to investigate the effects of green tea extract and its major constituent epigallocatechin-3-gallate (EGCG) on growth and severalhalitosis-related properties of S. moorei.Methods: A microplate dilution assay was used to determine the antibacterial activity of green tea extract and EGCG against S. moorei. Their effects on bacterial cell membrane integrity were investigated by transmission electron microscopy and a fluorescence-based permeability assay. Biofilm formation was quantified by crystal violet staining. Adhesion of FITC-labeled S. moorei to oral epithelial cells was monitored by fluorometry. The modulation of beta-galactosidase gene expression in S. moorei was evaluated by quantitative RT-PCR.Results: The green tea extract as well as EGCG inhibited the growth of S. moorei, with MIC values of 500 and 250 mu g/ml, respectively. Transmission electron microscopy analysis and a permeabilization assay brought evidence that the bacterial cell membrane was the target of green tea polyphenols. Regarding the effects of green tea polyphenols on the S. moorei colonization properties, it was found that biofilm formation on EGCG-treated surfaces was significantly affected, and that green tea extract and EGCG can cause the eradication of pre-formed S. moorei biofilms. Moreover, both the green tea extract and EGCG were found to reduce the adherence of S. moorei to oral epithelial cells. The beta-galactosidase activity of S. moorei, which plays a key role in VSC production, was dose-dependently inhibited by green tea polyphenols. In addition, EGCG at 1/2 MIC significantly decreased the beta-galactosidase gene expression.Conclusion: Our study brought evidence to support that green tea polyphenols possess a number of properties that may contribute to reduce S. moorei-related halitosis. Therefore, these natural compounds may be of interest to be used to supplement oral healthcare products.
