Doppler velocimetric parameters of the testicular artery in healthy dogs.

This study aimed to examine the Doppler velocimetric pattern of the testicular artery of small dogs in two different locations. Testes of 21 dogs were evaluated by two-dimensional ultrasonography to measure testicular volume and by Doppler ultrasonography to record the velocimetric patterns of the testicular artery in the spermatic cord and marginal location. The volume of left testes (4.70 ± 1.22 cm(3)) was significantly higher than the volume of the right testes (4.45 ± 1.17 cm(3)). Peak systolic velocity (PSV) of the left spermatic cord was significantly higher than the right side. End-diastolic velocity was significantly higher in the marginal artery than the spermatic cord on both sides; however, resistance and pulsatility indexes were significantly lower in the marginal artery. Results demonstrate the viability of Doppler ultrasonography for characterization of the testicular artery in small dogs and Doppler velocimetric values vary according to the location of measurement along the artery.

Pelvic differences between brachycephalic and mesaticephalic cats and indirect pelvimetry assessment

Pelvic measurements were carried out in cats with various cranial conformations to (1) determine pelvic morphometry, (2) compare any pelvic differences with cranial conformation and gender and (3) determine whether body biometrics can be used to predict pelvic measurements. Thirteen brachycephalic and 14 mesaticephalic female cats and 17 brachycephalic and nine mesaticephalic male cats were used. Body and external pelvic measurements, as well as pelvic radiographs, were performed. Brachycephalic females all had external pelvic and radiographic measurements that were significantly smaller than those of the mesaticephalic females, including smaller pelvic inlet and outlet areas and a smaller pelvic canal shape. Brachycephalic females had wider and flatter heads than do mesaticephalic females. Similarly, brachycephalic males all have radiographic pelvic measurements that are smaller than those of mesaticephalic males. Males had larger pelvis measurements than did their female counterparts for both cranial types, and indirect pelvimetry did not demonstrate good predictive value in determining the internal pelvic measurements. Thus, we conclude that pelvic differences exist between genders and between brachycephalic and mesaticephalic cats. Furthermore, body biometric measurements do not have good predictive value for determining internal pelvic measurements.

E-mail: mirley.souza@gmail.com This study aimed to assess whether there are differences in Doppler velocimetry pa- rameters 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 lar- ge 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.

Diagnóstico e tratamento de lúpus eritematoso discoide canino: Relato de caso

The Lupus Erythematosus immune complex disease (LE) consists of a set of autoimmune dermatopathies that can manifest in two main clinical presentations: Systemic Lupus Erythematosus (SLE) and Discoid Lupus Erythematosus (DLE). The clinical diagnosis of DLE can be challenging, due to the variety of symptoms that can occur both in lupus and in other dermatological conditions, which interferes with the early diagnosis and consequently a delay in the treatment and improvement of the patient. This study aims to report the importance of histopathological examination in the definitive diagnosis for treatment and favorable prognosis of canine poodle with DLE. A poodle dog was attended at the Metropolitan Veterinary Polyclinic HVM, presenting lesion in nasal area with previous treatments and no apparent improvment of the lesion. Laboratory and cytological exams were done to exclude other skin diseases. After an inconclusive result in the cytology, the histopathological examination was requested, to
