B-Mode and doppler sonography of the mammary glands in dairy goats for mastitis diagnosis

Contents This study aimed to evaluate the sonographic characteristics of the udder and teats and to determine the Doppler indexes of mammary artery in healthy and undergoing subclinical and clinical mastitis goats. Thirty animals among Saanen and Alpine Brown goats were arranged in three groups, healthy goats (HG), goats with subclinical mastitis (SMG) and goats with clinical mastitis (CMG). Using the B-mode, the sonographic characteristics (echotexture and echogenicity) and biometry (diameter and area of the udder cistern, diameter and area of the teat cistern and thickness of the teat wall) were evaluated. Using Doppler ultrasonography, the vascular indexes of the mammary artery were obtained. It was observed hyperechogenicity with solid component in the gland cistern when comparing animals with clinical mastitis and healthy mammary tissue. Regarding the echotexture of the breast tissue, there was heterogeneity in the mammary parenchyma on the three groups, for the milk, it was observed homogeneity for animals on HG and SMG and heterogeneity for animals on CMG. Grey-scale quantitative assessment revealed increase in echogenicity (mean value) for all the structures when comparing the three groups. Biometry did not reveal statistical difference between groups, for none of the evaluated structures. Doppler examination of the mammary artery showed the decrease of end diastolic velocity and raise of pulsatility index between groups. The association of B-mode and Doppler ultrasonography is useful for the evaluation of the udder of dairy goats with mastitis. It is a sensitive and specific method for the study of this disease. Doppler mode was unable to establish reliable criteria for diagnosis of subclinical mastitis. Moreover, the quantification of echogenicity is a useful technique for the evaluation of the milk in animals with mastitis; therefore, it is suggested that it can be used as complementary technique for the diagnosis of mastitis in goats.

Prevalence of anogenital warts in Men with HIV/AIDS and associated factors

Infection with human papilloma virus (HPV) is the most common sexually transmitted disease in the world. Among the 630 million new cases of HPV that occur each year, 30 million develop anogenital warts. Although subclinical infection with HPV is the most common cause, genital warts are also associated with immunosuppression caused by HIV. In view of the high prevalence of HPV/HIV co-infection particularly among men who have sex with men, the objectives of this study were to determine the prevalence of anogenital warts in men with HIV/AIDS and to identify associated factors. A cross-sectional study was conducted on 159 men with HIV/AIDS consecutively selected at a referral service in Botucatu, São Paulo, Brazil, in which the association between sociodemographic, behavioral and clinical variables and the presence of anogenital warts was evaluated. After hierarchical analysis of the data, variables presenting a p value ≤ 0.2 were entered into an unconditional multivariate logistic regression model. Forty-nine (31%) of the HIV-positive patients had anogenital warts. The mean age was 44.6 ± 9.6 years. The main factors associated with the presence of anogenital warts were irregular antiretroviral treatment and genital herpes(HSV). The present study demonstrate that anogenital warts occur in almost one-third of the male population infected with HIV and factors associated with a higher risk of being diagnosed with anogenital warts were irregular cART use and co-infection with HSV, other variables could not be associated.

Triiodothyronine and breast cancer

The thyroid hormones (THs), triiodothyronine (T3) and thyroxine (T4), are essential for survival; they are involved in the processes of development, growth, and metabolism. In addition to hyperthyroidism or hypothyroidism, THs are involved in other diseases. The role of THs in the development and differentiation of mammary epithelium is well established; however, their specific role in the pathogenesis of breast cancer (BC) is controversial. Steroid hormones affect many human cancers and the abnormal responsiveness of the mammary epithelial cells to estradiol (E2) in particular is known to be an important cause for the development and progression of BC. The proliferative effect of T3 has been demonstrated in various types of cancer. In BC cell lines, T3 may foster the conditions for tumor proliferation and increase the effect of cell proliferation by E2; thus, T3 may play a role in the development and progression of BC. Studies show that T3 has effects similar to E2 in BC cell lines. Despite controversy regarding the relationship between thyroid disturbances and the incidence of BC, studies show that thyroid status may influence the development of tumor, proliferation and metastasis.

Avaliação ultrassonográfica de crianças com hipotireoidismo congênito

To establish benchmarks and study some sonographic characteristics of the thyroid gland in a group of euthyroid children aged up to 5 years as compared with age-matched children with congenital hypothyroidism. Thirty-six children (17 female and 19 male) aged between 2 months and 5 years were divided into two groups - 23 euthyroid children and 13 children with congenital hypothyroidism - and were called to undergo ultrasonography. In the group of euthyroid children (n = 23), mean total volume of the thyroid gland was 1.12 mL (minimum, 0.39 mL; maximum, 2.72 mL); a homogeneous gland was found in 17 children (73.91%) and 6 children (26.08%) had a heterogeneous gland. In the group of children with congenital hypothyroidism (n = 13), mean total volume of the thyroid gland was 2.73 mL (minimum, 0.20 mL; maximum, 11.00 mL). As regards thyroid location, 3 patients (23.07%) had ectopic thyroid, and 10 (69.23%) had topic thyroid, and out of the latter, 5 had a homogeneous gland (50%) and 5, a heterogeneous gland (50%). In the group with congenital hypothyroidism, 6 (46.15%) children had etiological diagnosis of dyshormoniogenesis, 3 (23.07%), of ectopic thyroid, and 4 (30.76%), of thyroid hypoplasia. Thyroid ultrasonography is a noninvasive imaging method, widely available, easy to perform and for these reasons could, and should, be performed at any time, including at birth, with no preparation or treatment discontinuation, to aid in the early etiological definition of congenital hypothyroidism.

Caracterização histomorfológica de lesões granulomatosas sugestivas de tuberculose ganglionar e pulmonar em bovinos abatidos na região noroeste do estado de SãoPaulo

Tuberculosis infection among humans transmitted by products of animal origin can be caused by Mycobacterium bovis, a concern in developing countries, because the number of human cases is relatively high compared with countries that have implemented programs to eradicate bovine tuberculosis for many years. Because it is a chronic disease with subclinical evolution, it is transmitted to other animals in the herd livestock resulting in high loss losses resulting high (10 to 25%), as well as the zoonotic nature of the disease on public health. This work aimed to study the histomorphology of granulomas in samples of lymph nodes and lungs of animals with suggestive lesions of tuberculosis, as well as those similar to the sanitary inspection. The animals clinically healthy ante-mortem, were slaughtered in a slaughterhouse in the northwestern state of Sao Paulo between April 2008 and April 2009, considering that carcasses had lymph nodes with lesions typical of tuberculosis, exhibiting nodular and hemorrhagic appearance. The caseous or calcified lesions, purulent or not, of various sizes and shapes, were also evaluated. Of the 307,661 animals slaughtered in the mentioned period, 494 gross suggestive lesions of tuberculosis and from 29 cities in the state of Sao Paulo, 16 from Mato Grosso do Sul, Goias 15, one from Mato Grosso and Paraná. Among these, 200 samples (40,5%) were processed for histopathological evaluation by hematoxylin-eosin (HE) and 90 (45%) were subjected to Ziehl-Neelsen (ZN) and examined by light microscopy. In HE staining, histopathological changes of tuberculosis were found in 197 (98,5%), classified according to the stage of development adopted by Wango et al.(31), where 29 samples were included in stage I (14,5%), 53 in stage II (26,5%), 87 in stage III (43,5%), 28 in stage IV (14%). In the ZN staining Mycobacterium sp was found in 89 (99%) of the specimens. The rate of tuberculosis in the herd studied was 0,16%. We conclude that the identification of the disease in slaughterhouses and meat companies from significant gross lesions, enables the implementation of effective measures, specifically the origin of the disease in cattle herds, providing control measures to prevent its spread.
