RESUMO

This study aimed to evaluate the renal function of six bitches of various breeds and ages, with open pyometra, attended in the Small Animal Medical Clinic sector of the Veterinary Hospital from Federal University of Campina Grande, through the measurement of laboratory tests: urea and creatinine serum, dosage of the urinary Protein-Creatinine Ratio (PCR), urinary gamma-glutamyltransferase (GGT) and determination of the renal resistivity index (RI). The levels of urea and creatinine were elevated in 16.6% (1/6) of the female dogs; the urinary protein-creatinine ratio was increased in 66.6% (4/6), while the urinary gamma-glutamyltransferase value was elevated in 50% (3/6). The renal resistivity index was increased in the right and left kidneys by 66.6% (4/6) of bitches, with no statistical difference between them. It was concluded that the renal resistivity index was a practical and effective method to assist in the diagnosis of acute kidney injury, along with other early markers, such as PCR and urinary GGT.

RESUMO

Veterinary Ophthalmology provides complementary information for the diagnosis of ocular pathologies. Studies in wild species are essential. Among the diagnostic techniques in ophthalmology, two-dimensional ultrasonography stands out. The agouti is a rodent belonging to the Dasyproctidae family that has been widely used as an experimental model. For these animals, sight is one of the crucial senses for their survival. The aim of this study was to evaluate the effectiveness of the two-dimensional ocular ultrasound technique to obtain anatomical measurements and the external ophthalmic artery resistivity index, presumably normal in the species Dasyprocta prymnolopha. Forty eye bulbs of 20 adult rodents of the species were evaluated by ultrasonography. In these animals, B-mode echobiometry was performed using the transpalpebral approach and the hemodynamic study of the external ophthalmic artery using the color Doppler technique. All examinations were initiated by the left eye bulb and all measurements were performed by only one examiner. The collected data related to echobiometry were analyzed using Bioest 5.0 for Windows. Initially, normality was tested using the Shapiro-Wilk test for each parameter, then the paired t-test was performed, comparing right and left eyes, and a significance level of 5% (P < 0.05) was adopted. Based on the methodology used, the following values were obtained for the right and left eyeballs, respectively: anterior chamber thickness - mean of 1.28 ± 0.3 mm and 1.22 ± 0.1 mm; lens thickness - 8.27 ± 0.9 mm and 8.11 ± 0.9 mm; vitreous chamber thickness - 5.35 ± 0.48 mm and 5.30 ± 0.47 mm and axial length - 12.7 ± 0.9 mm and 13 ± 0.68 mm. The mean external ophthalmic artery resistivity values were 0.4305 ± 0.0390 and 0.4258 ± 0.0387 (right and left eye, respectively), characterizing a low resistance. There was no statistical difference between the right and left eyeballs in any of the studied parameters. The use of the convex transducer was feasible, promoting adequate contact with the ocular surface and images of satisfactory quality for obtaining measurements, similar to what was observed in studies evaluating the ocular biometry of primates and dogs. The anterior chamber thickness values in this experiment did not differ statistically between the antimers, as well as observed for dogs. The data obtained for lens thickness did not differ statistically for antimers, like those obtained for other rodent species evaluated with the same methodology. The mean values of vitreous chamber thickness were like those observed in chinchillas but correspond to about half of that obtained for capybaras. In this study, the external ophthalmic artery was characterized in all animals, but obtaining the spectral tracing was difficult due to its fine caliber. In wild animals, and especially in wild rodents, there are few data reporting the resistivity of the ophthalmic artery, and there is a lack of studies, which can be explained by the behavioral characteristics of defense and by the high susceptibility to stress in capture, since the performing the technique requires, as in other procedures, the use of chemical containment.

RESUMO

Background: Clinical care of cats with urethral obstruction is a common routine in feline clinical medicine and the re-establishment of urinary flow is essential for long-lasting correction of the pathophysiological alterations presented. For this chemical restraint is usually employed, that together with the alteration, increases the anesthetic risk of these patients. Improvement in anesthetic techniques, especially the loco-regional, may contribute to reducing the anesthetic risk of these patients and facilitate maneuvers to clear the obstruction. Thus the objective of the present study was to describe and assess the bilateral block technique of the pudendal nerve in 16 cats with urethral obstruction.Materials, Methods & Results: Sixteen male crossbred cats were used, with partial or total urethral obstruction, attended at the Veterinary Hospital of the Federal University of Campina Grande, PB, Brazil. The anesthetic block of the pudendal nerve trunk was carried out by placing the local anesthetic close to the ventral foramen of the second sacral vertebra, using a 13 x 0.45 mm needle attached to a 1 mL syringe. To assess the effectiveness of the bilateral block, the analgesia promoted was assessed using the substitute (“Reaction to Palpating the Surgical Wound” of subscale 1 (pain expression) of the “Compound Multi-dimensional Scale to Assess Post Operational Pain in Cats”. This assessment was made before the bilateral block (M0) and 10 min afterwards (M1) and the scores ranged from 0 to 3. In addition, a segmental assessment of the urethra was made, where, by passing a probe the sensitivity was assessed of the urethral ostium, penile and pelvic urethra and the relaxing of the external urethral sphincter. This assessment was made at M1 and classified as present or absent.[...](AU)

RESUMO

In order to evaluate the cranial spread of different volumes of iobitridol, by epidural lumbosacral route, 12 mongrel rabbits, 1.0±0.5 years old, weighing 2.4±0.4 kg were used. The animals were anesthetized with xylazine (5 mg/kg) and ketamine (20 mg/kg) intramuscularly, 15 minutes before of the lumbosacral puncture. Two groups were formed: iobitridol was administered at a volume of 0.33 mL/kg in the group 1 (G1) and at 0.22 mL/kg in the group 2 (G2). The heart (HR) and respiratory rates (f), duration of P-wave, PR interval, QRS complex and QT interval, oxyhemoglobin saturation (OS) and rectal temperature (RT) were evaluated, before epidurography and every 10 minutes after, for 60 minutes. The cranial spread of iobitridol and the ataxia produced were also analyzed. FC, f and RT reduced and duration of QT interval increased after anesthesia in both groups. The duration of PR interval and QRS complex increased in G1. The cranial limit of the migration of the contrast medium varied between the 4th lumbar vertebra and the 8th thoracic vertebra in G1 and between the 5th lumbar vertebra and the 11th thoracic vertebra in G2. Ataxia was moderate in both groups. It is concluded that the administration of iobitridol by the lumbosacral epidural route, associated with dissociative anesthesia with xylazine-ketamine, and in the volumes used and under the study conditions, causes tolerable changes in the parameters evaluated in healthy rabbits, and when used in this animal model there is no signs of neurotoxicity.(AU)

Com o objetivo de avaliar a migração cranial de diferentes volumes de iobitridol, administrado por via epidural lombossacra, bem como as possíveis alterações decorrentes dessa administração, foram utilizados 12 coelhos, sem raça definida, com 1,0±0,5 anos de idade e pesando 2,4±0,4 kg. Os animais foram anestesiados com xilazina (5 mg/kg) e cetamina (20 mg/kg), por via intramuscular, 15 minutos antes da punção lombossacra. Foram compostos dois grupos: grupo 1 (G1), onde foi administrado iobitridol, no volume de 0,33 mL/kg; e grupo 2 (G2), 0,22 mL/kg. Avaliaram-se as frequências cardíaca (FC) e respiratória (f), a duração da onda P, do intervalo PR, do complexo QRS e do intervalo QT, a saturação de oxihemoglobina (SPO2) e a temperatura retal (TR), antes da epidurografia e a cada 10 minutos após, durante 60 minutos. Também foram analisadas a migração cranial do iobitridol e a ataxia produzida. A FC, f e TR reduziram e a duração do intervalo QT aumentou após a anestesia em ambos os grupos. As durações do intervalo PR e do complexo QRS aumentaram no G1. O limite cranial da migração do meio de contraste variou entre a 4 vértebra lombar e a 8 vértebra torácica no G1 e entre a 5 vértebra lombar e a 11 vértebra torácica no G2. A ataxia foi moderada em ambos os grupos. Conclui-se que a administração do iobitridol pela via epidural lombossacra, associada à anestesia dissociativa com xilazina-cetamina, e nos volumes utilizados e sob as condições de estudo, causa alterações toleráveis nos parâmetros avaliadosem coelhos hígidos, e quando utilizado neste modelo animal não causa sinais de neurotoxicidade.(AU)

RESUMO

Objetiva-se com este relato descrever os aspectos radiográficos decorrentes da instabilidade atlantoaxial associada à agenesia do processo odontoide do áxis em uma cadela adulta. Clinicamente, a paciente apresentava apatia e tetraparesia. Foi realizado um exame radiográfico simples da região cervical, que permitiu a evidenciação de agenesia do processo odontoide do áxis, sem alterações articulares. Com a aplicação do cálculo do índice de normalidade atlantoaxial, obteve-se o valor de 0,103 mm, indicando a instabilidade dessa articulação. Como conduta, foi adotada uma terapia conservativa, recorrendo-se a colar cervical, restrição da movimentação e uso de anti-inflamatório. Diante do exposto, conclui-se que animais adultos sem sintomatologia prévia podem ser portadores dessa condição, e que o cálculo do IDA foi uma ferramenta eficaz para complementar a avaliação radiográfica subjetiva dessa articulação no cão deste relato. A paciente permanece estável, utilizando o colar cervical.

This report describes the radiographic findings in a case of atlantoaxial instability associated with agenesis of the odontoid process of the axis in an adult dog. Clinically, the patient presented apathy and tetraparesis. A simple radiographic examination of the cervical region was performed, which allowed the disclosure of agenesis of the odontoid process of the axis without articular changes. The atlantoaxial normality index (ANI) was 0.103 mm, indicating instability of the joint. A conservative approach was adopted by means of a cervical collar, movement restriction and anti-inflammatory therapy. We conclude that asymptomatic adult animals can be carriers of this condition, and that the calculation of the ANI was an effective tool to complement the subjective radiographic evaluation of this articulation on this report's dog. The patient remains stable with the cervical collar.

Clinicamente la paciente presentaba apatía y tetraparesia. Se realizó un examen radiográfico simple de la región cervical, que permitió evidenciar la agenesia de la apófisis odontoides del axis, sin otras alteraciones articulares. A través del cálculo del índice de normalidad atlantoaxial, se obtuvo un valor de 0,103 mm, indicando la inestabilidad de esa articulación. Se decidió realizar una terapia conservadora utilizando collar isabelino para limitar los movimientos, y el uso de antiinflamatorio. Teniendo en cuenta los resultados, se concluye que los animales adultos sin síntomas previos pueden ser portadores de esa condición, y que el cálculo del índice de normalidad atlantoaxial representó una herramienta eficiente como complemento del examen radiográfico subjetivo en el análisis de la articulación para el perro de este relato. La paciente permanece estable con el uso del collar cervical.
