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.

RESUMO.-[Avaliação Triplex Doppler dos testículos de cães de tamanhos diferentes.]Este trabalho teve como objetivo verificar se existem diferenças nos parâmetros dopplervelocimétricos entre cães de diferentes portes. Para tanto, foram utilizados 20 cães, sendo 10 cães de pequeno porte e 10 cães de grande porte. Foram avaliados pelo Triplex Doppler para localização da artéria testicular nos segmentos de cordão espermático, marginal ao testículo e intratesticular. Após isso, o Doppler espectral foi acionado para cálculo dos parâmetros de velocidade de pico sistólico (VPS), velocidade diastólica final (VDF) e índices de resistência (IR) e pulsatilidade (IP). O volume testicular médio do testículo esquerdo foi significativamente maior que o direito em ambos os grupos. Ao Doppler, foram observadas diferenças dos valores entre os portes, sendo as velocidades no cordão espermático superiores nos animais de grande porte (P < 0,05) e dentro dos grupos também foram observadas diferenças entre as regiões da artéria testicular. Diante do exposto, conclui-se que existem diferenças nos parâmetros dopplervelocimétricos quando comparados animais de diferentes portes, além disso, os parâmetros dopplervelocimétricos são diferentes dependendo da região em que são mensurados. INTRODUCTIONThe ultrasonographic evaluation of the testes allows the study of anatomy, parenchyma and adjacent structures, which is important to detect anatomical abnormalities, as well as guiding interventional procedures for diagnosis purposes (Nyland & Matton 2004). Two-dimensional ultrasound of the testes enables the assessment of echogenicity and echotexture, besides the measure of testicular volume, which may represent normal development of testes, serving as a tool in detecting testicular diseases (Dogra et al. 2003). 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.

The presence of trichobezoar in cats is characterized by the accumulation of hair in the gastric cavity, which may be associated with the presence of dermatitis caused by the presence of the mite Lynxacarus radovskyi. In the present report, a clinical case of a feline patient with diagnostic and surgical diagnosis of the presence of a trichobezoar with the presence of Lynxacarus radovskyi in a skin scrape examination was described.
