Objective: To know the usefulness of color and spectral doppler in evaluation of solid breast masses using vascularity and resistive index. Material and methods: We performed duplex doppler sonography on 100 patients presenting with breast mass. Resistive index and vascularity of the vessels were detected and analyzed and correlated with histopathological results. Results: 70% of the benign lesions were found having ri below 0.8 and 45 out of 50 patients had low vascularity.43 malignant lesions had high vascularity and 80% had ri above 0.8. Conclusion: High flow visualization on power doppler and indicates a higher possibility of malignancy lesions with ri greater than 0.8 gives high probability of malignancy.

ABSTRACT The aim of this study was to determine the vascular indices of adrenal blood flow in healthy dogs (systolic velocity - SV; diastolic velocity - DV; resistance index - RI). Eighteen dogs (thirty six adrenal) were studied. Physical examination, biochemical profile and dexamethasone suppression test were performed to determine general health status. Echotexture, size, contours and margins, and overall shape of the adrenal gland (right and left) were assessed via ultrasound. By spectral Doppler of the phrenic-abdominal artery, the SV, DV, and RI were acquired. Animals did not show alterations in clinical and laboratory examination and suppression of cortisol. Normal homogeneous and echotexture, regular contours and margins and normal shape and size were verified via B mode. Spectral Doppler of the phrenic-abdominal artery showed monophasic-patterned waves and low vascular resistance and systolic peak evident with means values: left adrenal - SV = 31.34cm/s, DV = 9.54cm/s and RI = 0.69; and right adrenal - SV = 27.83cm/s, DV = 7.71cm/s and RI = 0.68. Doppler evaluation of adrenal was easily implemented and may provide base line data in the study, allowing for the use of this technique as a diagnostic tool for diseases of the dog's adrenal.

This study aimed to assess whether there are differences in Doppler velocimetry parameters between different sizes. Twenty dogs were equally divided into small and large groups used in this study. The dogs were evaluated using Triplex ultrasound. Testicular artery was located by Colour Doppler in the spermatic cord, marginal to the testes and intratesticular segments and then, spectral Doppler were used to calculate: peak systolic velocity (PSV), end diastolic velocity (EDV), resistance index (RI) and pulsatility index (PI). The mean testicular volume in the left side was significantly higher than the right side, in both groups. Doppler examination showed higher velocities (EDV) at spermatic cord in large dogs; marginal to the testes was observed higher velocities in small dogs; intratesticular region no differences were observed (P < 0.05) and within the groups differences between segments of the artery were also observed for each parameter. The results showed that there are differences in Doppler velocimetry parameters between different sizes.

ABSTRACTPostpartum uterine diseases such as metritis and endometritis are highly prevalent in dairy cows. These diseases negatively affect the reproductive performance and consequently economic activity. Cows in the puerperal period presenting endometritis may have alterations in the hemodynamics of the uterine tissue and the uterine arteries, which differ them from healthy cows. Therefore, this study aimed to use the Doppler ultrasonography to describe the hemodynamic changes in the uterus of cows showing endometritis diagnosed between 25 - 35 days postpartum. Eighty-nine Holstein Friesian females with 25 to 35 days postpartum were studied. Cows were assigned to two experimental groups, infected or not infected, according to the results of the endometrial cytology. Clinical examination, vaginoscopy, Doppler ultrasound and sample collection (saline solution was injected and recovered by endoscopie method aiming cytological and microbiological evaluation of the uterus) were also performed. Cows with endometritis had the cervix (P = 0.040) and the left horn (P = 0.020) increased compared to healthy cows. 78.6% of the endometritic cows showed abnormal uterine discharge, while 57.6% of healthy cows had this same condition (P = 0.0005). The spectral Doppler evaluation of the uterine arteries revealed no differences between groups. Bacillus spp., Trueperella pyogenes, Escherichia coli and Staphylococcus intermedius were the most isolated bacteria among samples. Higher score or increase of uterus vascularization of the endometrial Doppler was correlated with Trueperella pyogenes (P = 0.0003) and intrauterine heterogeneous content (P = 0.0047). Finally, mesometrial Doppler was correlated with endometrial Doppler (P < 0.001), uterine bacteria (P = 0.001) and intrauterine heterogeneous content (P = 0.049). Regarding the evolution of uterine alterations, Doppler ultrasonography provides fast results and is a lesser invasive technique such as uterus biopsie and endometrial citology and gives answers about fertility and uterus health.

In Pregnancy

Acute appendicitis is the most common acute surgical infection during pregnancy. Although usually pyogenic in origin, parasitic infections account for a small percentage of cases. Despite the relatively high prevalence of acute appendicitis in our environment, it is not commonly associated with schistosomiasis. We report here the association of pregnancy and appendicitis caused by Schistosoma haematobium. Schistosomiasis is very common complication of pregnancy in hyperendemic areas. Schistosome egg masses can lodge throughout the body and cause acute inflammation of the appendix, liver and spleen. Congestion of pelvic vessels during pregnancy facilitates passage of eggs into the villi and intervillous spaces, causing an inflammatory reaction. Tourism and immigration make this disease a potential challenge for practitioners everywhere.
