Electrocardiographic and Echocardiographic Parameters in Pega Breed Donkeys: A Descriptive Study.

Clinical, electrocardiographic and echocardiographic parameters in Pega donkeys are scarce in the literature; hence, this study was performed to describe the echocardiographic and electrocardiographic measurements in Pega breed donkeys. The objectives of this study were to describe and illustrate the clinical, electrocardiographic, and echocardiographic parameters in Pega donkeys used for reproduction. Fifty Pega breed donkeys were evaluated, with an average age of 3.4 years and with 20 males and 30 females. In each animal, the electrocardiographic examination at rest was performed using the TEB® computerized system, and the echocardiographic examination was performed using an ultrasound device with a Doppler function multifrequency sectorial transducer in 2D mode (Sonosite® M turbo). Standardizing the electrocardiographic and echocardiographic parameters for the Pega breed donkey can contribute to future assessments regarding possible changes that excessive effort can promote in these parameters to a management engrossed on animal welfare.

Uso da miltefosina no tratamento clínico de cães com leishmaniose visceral: revisão de literatura / Use of miltefosin in the clinical treatment of dogs with visceral leishmaniosis / Uso de miltefosina en el tratamiento clínico de perros con leishmaniosis visceral: revisión de la literatura

A leishmaniose visceral canina é uma doença de caráter zoonótico, acometendo os seres humanos e diversas espécies de animais silvestres e domésticos. Objetivou-se com o presente estudo realizar uma revisão de literatura sobre o uso da miltefosina no tratamento clínico de cães com leishmaniose visceral. Trata- se de uma revisão de literatura, a qual foi realizada por meio de consultas à periódicos e livros presentes na biblioteca do Cesmac. Foram utilizadas bases de dados como: portal Capes, SCIELO, Google Acadêmico; pesquisa em monografias, teses e dissertações. Causada pelo protozoário Leishmania chagasi, sendo o cão doméstico o principal reservatório desse protozoário. Por representar um problema grave de saúde pública e ser considerada uma doença potencialmente fatal (quando não tratada precocemente e adequadamente), faz- se importante que o clínico esteja familiarizado com os sinais clínicos, exames complementares e principais protocolos terapêuticos, em especial a utilização da miltefosina no tratamento da leishmaniose visceral em cães. Por ser uma zoonose que causa graves problemas de saúde pública e que vem crescendo cada vez mais no Brasil, cabe aos médicos veterinários assumirem o compromisso na conscientização sobre a importância do diagnóstico precoce além de promoverem o bem-estar animal e a saúde pública.(AU)

Canine visceral leishmaniasis is a zoonotic disease, affecting humans and several species of wild and domestic animals. The objective of the present study was to carry out a literature review on the use of miltefosine in the clinical treatment of dogs with visceral leishmaniasis. This is a literature review, which was carried out through consultations with periodicals and books present in the Cesmac library. Databases such as: Capes portal, SCIELO, Google Scholar; research in monographs, theses and dissertations. Caused by the protozoan Leishmania chagasi, with the domestic dog being the main reservoir of this protozoan. As it represents a serious public health problem and is considered a potentially fatal disease (when not treated early and properly), it is important that the clinician is familiar with the clinical signs, complementary exams and main therapeutic protocols, especially the use of miltefosine in the treatment of visceral leishmaniasis in dogs. As it is a zoonosis that causes serious public health problems and that has been growing more and more in Brazil, it is up to veterinarians to make a commitment to raise awareness of the importance of early diagnosis in addition to promoting animal welfare and public health.(AU)

Utilização da fisioterapia na reabilitação de bezerro com poliartrite e paresia neuromuscular: relato de caso / Use of physiotherapy in the rehabilitation of calves with polyarthritis and neuromuscular paresis: case report / Uso de la fisioterapia en la rehabilitación de un ternero con poliartritis y parisia neuromuscular: reporte de caso

A reabilitação animal na medicina veterinária é um campo recente, porém crescente a cada dia. Neste sentido, a fisioterapia veterinária atua trazendo inúmeros benefícios, como melhoria dos movimentos, redução da dor, edema e outras. Interfere ainda no tempo de recuperação, redução de custos para o proprietário, podendo ser hoje utilizada como um tratamento na recuperação pós-cirúrgica. Desta forma, objetivou-se relatar o uso da fisioterapia em uma bezerra com poliartrite e paresia neuromuscular. O animal apresentou um aumento de volume nas articulações cárpicas e társicas após histórico de onfalite, permanecendo em decúbito esternal por vários dias. O proprietário resolveu aplicar ferro dextrano na região glútea do animal, o que causou uma lesão de nervo isquiático. Foram instituídos protocolos medicamentosos e fisioterápicos, que culminaram no estímulo da marcha, propriocepção, além de hipertrofia muscular. Porém, em virtude de complicações resultantes de onfalite, o animal veio a óbito.(AU)

Animal rehabilitation in veterinary medicine is a recent field, but growing every day. In this sense, veterinary physiotherapy works bringing numerous benefits, such as improved movements, reduced pain, edema and others. Reducing the recovery time, reducing costs for the owner, and today it can be used as a treatment in post-surgical recovery. In this sense, the objective was to report the use of physiotherapy in a heifer with polyarthritis and neuromuscular paresis. The animal showed an increase in volume in the carpal and tarsal joints after a history of omphalitis, remaining in sternal decubitus for several days. The owner decided to apply iron dextran to the animal's gluteal region, which caused an injury to the sciatic nerve. Medicinal and physical therapy protocols were instituted, which culminated in the stimulation of gait, proprioception, in addition to muscle hypertrophy. However, due to complications resulting from omphalitis, the animal died.(AU)

Effects of clamping umbilical cord on the neonatal viability of puppies delivered by cesarean section.

In human neonates, when the umbilical cord is kept intact postpartum, blood continues to flow to the neonate, but this procedure might be difficult in dogs owing to a shorter umbilical cord and several neonates in a litter. However, it might be possible to detach the placenta and keep the umbilical cord intact, allowing residual blood to flow to the puppies. This study compared the effects of clamping versus no clamping of the umbilical cord in dogs born by cesarean section on neonatal vitality. The puppies were assessed by Apgar and reflex scores. Fifty puppies delivered from 16 bitches were randomly allocated to receive immediate umbilical cord clamping (n=25) or no clamping for at least 3 min after the onset of breathing (n=25). The puppies were assessed during the first 5 min of life and 10 min after the first assessment. The no clamping group showed significantly higher Apgar scores (second assessment, P<0.01) and reflex scores (first and second assessments, P<0.05) than the clamping group, implying higher vitality in the no clamping group. The differences observed between the moments (first versus second assessment) of each group was significant (P<0.01), revealing higher vitality in the second assessment. The results suggest that keeping the umbilical cord intact for at least 3 min after the onset of breathing may contribute to increased vitality in puppies delivered by cesarean section without any negative consequences.

Progesterone levels and days to luteolysis in mares treated with intrauterine fractionated coconut oil.

Intrauterine plant oil infusion, including fractionated coconut oil, has been previously found to be a safe, inexpensive, and reversible method of prolonging the luteal phase in mares when administered on Day 10 of the estrous cycle. Our objective was to understand the uteroovarian response to the administration of fractionated coconut oil infusion in the uterus of diestrous mares. We hypothesized that intrauterine coconut oil administration on Day 10 would prolong luteal life span in a dose-dependent fashion and would result in higher serum progesterone levels than untreated mares at the expected time of luteolysis. Light-horse mares (n = 18) were examined using transrectal palpation and ultrasonography to determine if they had a normal interovulatory interval and were then examined daily in estrus until the day of ovulation (Day 0) and then every other day during an estrous cycle. Jugular blood was drawn on Day 11, Day 13, Day 15, and Day 17, centrifuged, and serum stored until assayed for progesterone (P4; Siemens Coat-a-Count Progesterone RIA, Los Angeles, CA, USA). Mares were randomly assigned to treatment and studied over one to two estrous cycles with a rest cycle after each treatment cycle. Groups were: control (n = 5), fractionated coconut oil 1.0 mL (Miglyol 810; Sasol Oil, Witten, Germany) infused in the uterus with an artificial insemination pipette on Day 10 (Group 1; n = 5) and fractionated coconut oil 0.5 mL infused in the uterus with an embryo transfer gun, on Day 10 (Group 2; n = 5). All statistical analyses were performed using analytical software (Stata SE, version 13.1, College Station, TX, USA) at P < 0.05. Data were first evaluated using the Shapiro-Wilk test for normality. Differences between groups in days to luteolysis (DTL) were examined using analysis of variance and Bonferroni, and the effect of day and treatment on P4 levels were examined using the Kruskal-Wallis and Dunn's all pairwise test. There was a significant difference in DTL between the groups (P = 0.0083), with fewer DTL in Group 1 compared to control (P = 0.011) and to Group 2 (P = 0.034). There was a significant effect of day (P < 0.0001) on P4 levels with Day 11 P4 levels higher than Day 15 and Day 17 and Day 13 P4 levels higher than Day 15 or Day 17 (P < 0.03). There was a significant effect of treatment group (P = 0.0098) on P4 levels with control and Group 2 levels higher than Group 1 mares (P = 0.0012, P = 0.0495, respectively). We concluded that intrauterine administration of 1 mL of fractionated coconut oil lowered P4 levels in diestrus in a dose-dependent fashion and did not prolonged the luteal phase of the mares.

The normal electrocardiograms in the conscious newborn lambs in neonatal period and its progression.

BACKGROUND: Veterinary cardiology, especially electrocardiography, has shown major advancements for all animal species. Consequently, the number of ovine species used as experimental animals has increased to date. Few studies have been published on ovine systematic electrocardiography, particularly with respect to lamb physiology and neonatology. This study aimed to standardize the values of normal waves, complexes, and intervals of the electrocardiogram (ECG) in clinically Bergamasca healthy neonatal lambs, used as experimental animals. Serial computerized electrocardiography was performed in 10 male and 12 female neonates on the 1st, 7th, 14th, 21st, 28th, and 35th days of age. The following parameters were analyzed: heart rate and rhythm, duration and amplitude of waves, duration of intervals, and heart electrical axis. RESULTS: During the first 35 days of life, (1) the sinusal heart rhythm was predominant, (2) there was a progressive decrease in the heart rate and R and T wave amplitude, and (3) a progressive increase in the PR, QT, and RR intervals. Finally, we confirmed that various components of neonatal evolution were more discernible in the augmented unipolar leads (aVF), which we recommend should be preferentially used in future studies. No significant statistical alterations were observed between males and females in relation to the analyzed parameters. CONCLUSIONS: The information assimilated in this study is anticipated to enhance the diagnosis of multiple congenital heart defects in Bergamasca lambs and could be implemented in studies that use ovine species as experimental models.
