Dermoscopy is a non-invasive diagnostic method performed in vivo, is quick, painless and does not harm the skin. It is used as a complementary exam and allows the observation of structures of the epidermis, the dermoepidermal junction and the superficial papillary and reticular dermis, being considered a link between the clinical picture (macroscopic) and the histopathological exam. In order to conduct a systematic review of articles published with dermoscopy in animals, through a literature review of the concepts, techniques and applications of this examination in Veterinary Medicine, an electronic search was carried out using the databases PubMed, Scielo, CAFe, Wiley online library and Google scholar. Twelve articles were found, 5 (41,66%) about canines, 4 (33,33%) about felines and 3 (25%) about horses. These studies used dermoscopy in the evaluation of normal feline and equine skin, feline and canine dermatophytosis, pattern of alopecia in dogs, acral congenital superficial dermal lymphatic malformations in cats and description of colorimetric pattern in dogs with erythroderma. Through this research, it was demonstrated that Dermatoscopy is still incipient in Veterinary Medicine, but with promising results. The dermoscopic examination proved to be useful to describe normal skin, as a screening and to aid in the conclusion of the diagnosis of some skin diseases in animals. Although researchers are interested in the subject, and the exam's potential, it is still necessary to carry out more research to identify new applicability of dermoscopy and dermoscopic patterns among the different skin diseases that affect animals. La dermatoscopia es un método de diagnóstico no invasivo, realizado in vivo, rápido, indoloro y no daña la piel. Se utiliza como examen complementario y permite la observación de estructuras de la epidermis, unión dermoepidérmica y dermis papilar y reticular superficial, considerándose un vínculo entre el cuadro clínico (macroscópico) y el examen histopatológico. Para realizar una revisión sistemática de los artículos publicados con dermatoscopia en animales, mediante de una revisión bibliográfica de los conceptos, técnicas y aplicaciones de este examen en Medicina Veterinaria, se realizó una búsqueda electrónica utilizando las bases de datos PubMed, Scielo, CAFe, Wiley online library y Google scholar. Se encontraron 12 artículos, 5 (41,66%) sobre caninos, 4 (33,33%) sobre felinos y 3 (25%) sobre caballos. Estos estudios utilizaron dermatoscopia en la evaluación de piel felina y equina normal, dermatofitosis felina y canina, patrón de alopecia en perros, malformaciones linfáticas dérmicas superficiales congénitas acrales en gatos y descripción del patrón colorimétrico en perros con eritrodermia. Mediante esta investigación se demostró que la dermatoscopia aún es incipiente en Medicina Veterinaria, pero con resultados prometedores. El examen dermatoscópico demostró ser útil para describir la piel normal, como cribado y para ayudar a la conclusión del diagnóstico de algunas enfermedades de la piel en animales. Aunque los investigadores están interesados en el tema y el potencial del examen, aún es necesario realizar más investigaciones para identificar una nueva aplicabilidad de la dermatoscopia y los patrones dermatoscópicos entre las diferentes enfermedades de la piel que afectan a los animales.

O monitoramento do ciclo é um procedimento básico, porém complexo em animais selvagens. Tem-se desenvolvido métodos não invasivos para avaliar o perfil hormonal reprodutivo desses animais expandindo o conhecimento sobre a fisiologia reprodutiva de primatas em cativeiro e vida livre. O presente estudo visa monitorar a atividade folicular e as concentrações fecais de metabólitos de progesterona para ampliar os conhecimentos sobre a fisiologia reprodutiva dessa espécie. Foram utilizadas 12 fêmeas adultas, pertencentes à colônia de reprodução de macacos-da-noite do CENP. O estudo foi realizado a partir do exame ultrassonográfico do ovário e colheita de fezes para monitoramento dos níveis de metabólitos de progesterona dos animais por enzimaimunoensaio. Por meio da dosagem de metabólitos de progesterona foi possível apenas sgerir o ciclo da espécie para o período estudado. Porém, os níveis basais (2,1 ± 0,8 ng/g de fezes secas), a médio do pico (36,6 ± 8,6 ng/g fezes secas), os níveis médios (4,7 ± 1,8 ng/g de fezes secas) e os valores mínimo (0,4 ng/g de fezes secas) e máximo (49,9 ng/g de fezes secas) de metabólitos de progesterona foram determinados para espécie em cativeiro sob estas condições. A determinação do pico e concentrações basais de metabólitos de progesterona, conjuntamente a avaliação ultrassonográfica são ferramentas não invasivas e factíveis na avaliação do ciclo estral de macacos-da-noite Owl Monkeys are considered excellent experimental models and can contribute to the development of biotechnologies of reproduction in primates. Monitoring the reproductive cycle is a basic procedure, however complex in wild animals. Noninvasive methods has been developed to assess the reproductive hormonal profile of these animals expanding knowledge on reproductive physiology of primates in captivity and the wild. This study aims to monitor follicular activity and fecal progesterone levels to increase knowledge about reproductive physiology of this species. 12 adult females belonging to the breeding colony of owl monkeys of CENP were used. The study was performed using the ultrasound examination of the ovaries and feces collection for monitoring the levels of metabolites of progesterone by enzymeimuneassay. By progesterone assay we may suggest the cycle of the species for the period studied. However, the baseline levels (2.1 ± 0.8 ng/g), mean peak (36.6 ± 8.6 ng/g), mean levels (4.7 ± 1.8 ng/g) and the minimum (0.4 ng/g) and maximum (49.9 ng/g) metabolites of progesterone were determined for the specie in captivity. The determination of the peak and basal levels of progesterone together to the sonographic evaluation are noninvasive and feasible in the evaluation of the estrous cycle in owl monkeys

Made available in DSpace on 2020-12-10T18:04:14Z (GMT). No. of bitstreams: 0 Previous issue date: 2013-01-01 Background: Cases of ventricular foreign bodies are common in some species of birds. Moreover, ventricular impactions may develop depending on the type of the material ingested. The diagnosis is based on physical examination, radiography, endoscopy and surgical exploration. The choice of the treatment basically depends on the nature of the foreign body. Endoscopy is a less invasive approach that can be used in some situations, in some species. The benefits of endoscopic approaches are wide, as traditional approaches are more invasive and inflict a higher postoperative morbidity and mortality. However, the correct endoscope technique never been described. This study reports a case of a foreign body in a toucan's ventriculus, removed using a standard operative laparoscope/nephroscope. Case: A young Toco Toucan (Ramphastos toco) was referred to the Veterinary Hospital (Sao Paulo State University FCAV/UNESP) by the State Environmental Guard. Survey radiographs indicated a foreign body in the ventriculus. The physical exam revealed apathy, but the bird was responsive to handling. The patient was pinioned. Based on the size of the foreign body, the endoscope retrieval was the first treatment option. The patient was fasted for 6 hours and anesthetized with isoflurane. The rigid endoscope/laparoscope with working channel was carefully passed through the esophagus, into the ventriculus. This view was impaired by a large amount of fibrin and gastroesophageal mucus, which was rinsed with normal saline and aspirated through the operating channel. There was marked hyperemia on the ventriculus mucosa and a large amount of fibrin and gastroesophageal mucus. The foreign body was retrieved using a standard 10-mm 0 degrees rigid laparoscope/nephroscope with working channel, and a 42 cm long, 5-mm atraumatic laparoscopic Babcock forceps by gentile traction and axial rotation. The overall intervention time was 24 min, since mask induction until foreign body retrieve. The patient recovered with no complications in the early postoperative period and convalesced completely and uneventfully following 2 days. Discussion: The operative rigid endoscope allowed for both visualization of the oral cavity, esophagus, proventriculus and ventriculus and foreign body removal, through the working channel, demonstrating the potential benefits and feasibility of such approach in birds. Nevertheless, up to date, endoscopy have been used in toucans only for sex determination. The current report demonstrated the effectiveness of endoscopy in order to avoid the risk of death due to a surgical approach. Gastrointestinal foreign bodies are common indication for endoscopic approach. If the foreign body is present in the crop, it is easily removed with the use of an endoscope and grasper forceps, or by ingluviotomy. Even though the foreign body passes into the proventriculus or ventriculus, rigid endoscopy may still be the best treatment option. The 30 degrees Trendelenburg positioning was crucial for the complete success of the procedure, not only for avoiding the risk of fluid aspiration, but also for improving the access to the ventriculus.

Foram realizados exames ultrassonográficos da região pélvica, a fim de comparar as dimensões uterinas com o peso, idade (infantil, juvenil, subadulta, adulta jovem e adulta) e número de partos (nulípara, primípara e multípara) e comparar as dimensões ovarianas com o peso e a idade. O volume uterino (VU) foi diretamente proporcional ao número de partos, fator mais importante no crescimento uterino das fêmeas adultas (p < 0,05). O peso e a idade demonstraram uma correlação positiva com o VU (r = 0.5354, r = 0.6489, p < 0.01), respectivamente. O volume dos ovários cresceu proporcionalmente a idade das fêmeas (p < 0,05). A puberdade foi o período de maior crescimento tanto do útero como do ovário We aimed to evaluate the uterine and ovarian volumes of owl monkeys in different age groups with different numbers of live births and to analyze the interaction between both. We performed pelvic ultrasound exams to compare the uterine measurements with weight, age (infant, juvenile, subadult, young adults, and adults) and the number of live births (nulliparous, primiparous, and multiparous) and to compare the ovarian measurements with weight and age. The uterine volume (UV) was directly proportional to the number of parturitions, which was the most important factor in the uterine growth of adult females (P < 0.05). The body weight and age of the animals showed a high positive correlation with UV (r = 0.5354, r = 0.6489, P < 0.01), respectively. The volume of the ovaries grew in proportion to the age of the females (P < 0.05). Puberty was the period of greatest uterine and ovarian growth

This study aimed to characterize anatomical and biochemical properties of owl monkey kidneys in order to provide normal reference values. Sixty-nine Aotus azarai infulatus (45 males and 24 females) were divided into four different age groups (AG1: 3months?1 year; AG2: 2?3 years; AG3: 4?6 years; and AG4: over 7 years old). The monkeys were evaluated with a serum chemistry profile, focusing on serum creatinine (SCr) and blood urea nitrogen (BUN) and with ultrasound. Mean body mass differed among the age groups. This significance was attributed to AG1 body mass being significantly lower than in AG2 and that in both AG2 and AG3 being significantly lower than in the two older age groups (AG3 and AG4). SCr and BUN concentrations differed significantly between the sexes and SCr level correlated positively with age. In contrast, renal measurements did not differ between males and females. Left and right renal volumes did not differ significantly within age groups, or among AG2, AG3, and AG4. Renal volumes in AG1, however, while not differing from those in AG2, did differ significantly from those in AG3 and AG4. In conclusion, this study provides ultrasonographic reference values for the morphology the kidneys in A. a. infulatus. Evidence is also provided that SCr and BUN levels in owl monkeys are influenced by the sex and age of the individual, factors that should be considered when interpreting test results.

Este trabalho objetivou estabelecer um protocolo de contenção física tendo em vista a realização de exames ginecológicos e obstétricos por ultrassom em macacos-da-noite. As fêmeas foram contidas manualmente e foram alimentadas com frutas antes, durante e após o procedimento. A freqüência cardíaca inicial e final (FC1 e FC2) de cada fêmea foi calculada com base no intervalo entre picos sistólicos. O estresse causado pela contenção inicial aumentou a atividade simpática, elevando a FC1. A oferta das frutas aos animais favoreceu a modulação parassimpática, o que justifica a redução na FC2. Isso foi observado nos exames ginecológicos e obstétricos. The objective of this study was to establish a physical restraint protocol for gynecological and obstetric examination using ultrasound in Aotus azarai infulatus. The study was conducted with 10 previously established adult couples, evaluated during two different time periods (P1and P2). In P1, the conditioning was carried out by daily repetition of the gynecological exam associated with the offering of fruits before, during and after the exam. In P2, gynecological examinations were performed on nonpregnant females (n = 6), and obstetric examinations on those who became pregnant (n = 3). The exams were performed using the Medical SonoAce 9900®ultrasound equipment equipped with a multifrequential linear array probe (5-12 MHz). The initial and final heart rate (HR1 and HR2) for each female were calculated based on the interval between systolic peaks. No significant differences were observed in the heart rates in terms of time of examination, suggesting that the time did not interfere in the variables analyzed during the exams. The gynecological and obstetric exams presented a HR2 lower than HR1 during the two periods evaluated (p
