RESUMO

ABSTRACT: The aim of this study was to evaluate the effects of Allopurinol in foals born from mares with placentitis. Twenty foals were assigned into two groups: Healthy foals (n=10), born from healthy mares and Placentitis foals (n=10), born from mares with placentitis. Five foals from each group were randomly assigned to a treatment or control group. Treatment groups received Allopurinol (40mg kg-1 orally six hours after birth). Blood samples were collected for estimation of hematological variables and serum concentration of calcium, chloride, creatinine, phosphorus, glucose, lactate and magnesium. Placentitis foals presented leukopenia and neutropenia when compared with Healthy foals, at birth. The white blood cell (WBC) count was lower in the Placentitis foals untreated at 12 hours. No adverse effects related to the use of Allopurinol were detected. Treated Placentitis foals showed higher serum calcium and glucose levels within 12 hours than untreated Placentitis foals. Administration of Allopurinol PO in foals born from mares with placentitis did not result in adverse effects and can help in stabilizing serum calcium and glucose levels.

RESUMO: Este estudo teve por objetivo avaliar os efeitos da administração por via oral de Alopurinol em potros nascidos de éguas com placentite. Vinte potros foram divididos em dois grupos: potros saudáveis (n=10), nascidos de éguas sem placentite, e potros placentite (n=10), nascidos de éguas com placentite. Cinco potros de cada grupo foram selecionados aleatoriamente para compor o grupo tratado ou controle. Os grupos tratados receberam Alopurinol (40mg kg-1 PO na sexta hora de vida). Foram coletadas amostras sanguíneas para realização de análise hematológica e avaliação das concentrações séricas de cálcio, cloretos, creatinina, fósforo, glicose, lactato e magnésio. Os potros placentite apresentaram leucopenia e neutropenia, comparado com os potros saudáveis no momento do nascimento. O grupo placentite não tratado apresentou leucopenia no momento 12 horas. Não foram observados efeitos adversos relacionados ao uso do Alopurinol. O grupo placentite tratado apresentou maiores concentrações de cálcio e glicose em relação ao grupo placentite não tratado, nas 12 horas. A administração de Alopurinol por via oral em dose única em potros nascidos de éguas com placentite não resultou em efeitos adversos e pode ter contribuído para a estabilização dos níveis de cálcio e glicose.

RESUMO

Background: Aneurysm is a vascular disease that causes the partial rupture of arteries and veins and subsequent blood leakage due to the weakening of the vessels elastic middle layer. Venous aneurysms in horses are rare, but the arterial aneurysms are commonly reported. The aim of this paper is to report a rare occurrence of jugular external aneurysm in a horse and propose the inclusion this disease as a differential diagnosis, both because it is rare in this specie and invariably fatal. The medical examination showed a firm well-defined mass, painless, nonpulsatile on palpation and with no changed in the local temperature. Case: The horse was referred to the Veterinarian Hospital of the Federal University of Pelotas (UFPel, RS-Brazil. It was a male, Crioulo breed, 10 years old, used as stallion. The owner reported a swelling in the pectoral region that occurred after a trauma episode that had gradually grown for two years. The patient was clinically stable, and would undergo surgery extirpation for aesthetic matters. Clinical examination showed the swelling was circumscribed and centralized and it presented about 20 centimeters in diameter. The ultrasound of the pectoral area showed an anechoic structure with hyperechoic spots inside limited by an hyperechoic layer similar to a fibrous capsule. Presumptive diagnostics were of: hematoma, subcutaneous abscess, neoplasia, and [...](AU)

RESUMO

Background: The equine placenta is the organ where gas and nutrients are exchanged between the mare and the fetus and, as such presents two main functions: protection and regulation of the fetal environment. Maternal or placental disorders can lead to fetal or neonatal impairment, fetal death, development of abnormalities, dystocia, or to the delivery of premature or dysmature foals. The aim of this work is to report the placental findings, the clinical evaluation and the therapeutic measures adopted during the clinical monitoring of a foal birth from a mare with placentitis.Case: The patient is a Thoroughbred mare, 18 years-old, from a farm in the south region of Brazil. The mare was submitted to colic surgery 90 days prior to delivery. The gestational length was 365 days and the mare did not present any symptoms of placentitis during pregnancy. At delivery both the amniotic fluid and the foal showed meconium staining, suggesting passage of intrauterine meconium. The time lapsed from birth to the observation of postural and behavioral reflexes was: eight min to the adoption of sternal recumbency; 35 min to begin sucking reflexes, and 110 min to stand. After the observation of the sucking reflexes, the foal received 250 mL of colostrum with a bottle. The foal weight at birth was 50 kg. Yellow/brownish stains covering on the allantoic surface to its full extent were identified...

A placenta é um órgão fundamental na relação materno-fetal e deve ser considerada como um reflexo das condições nutricionais, metabólicas, endócrinas e vasculares maternas, além de ser um indicativo da condição clínica e metabólica do neonato [11]. A placenta apresenta duas grandes funções: de proteção e de regulação do ambiente fetal, atuando como órgão de trocas respiratórias e de nutrientes entre a égua e o feto [28]. O impacto das desordens de origem materna ou placentária no ambiente intrauterino, geralmente resulta em comprometimento fetal ou neonatal decorrentes de um ou da combinação de três fatores: hipóxia, infecção e transtorno no desenvolvimento dentro do útero [5].O Comprometimento fetal pode resultar no nascimento de um potro prematuro ou dismaturo, sendo os efeitos do comprometimento neonatal dependentes da natureza, duração, severidade e estágio da gestação no qual ocorreu a condição de estresse [5].Em quadros de hipóxia ocorre uma redistribuição do débito cardíaco para manter os órgãos vitais (coração, cérebro e adrenais), com comprometimento de outros órgãos [28]. O feto equino apresenta um mecanismo de redução da demanda de oxigênio quando exposto a hipó- xia, diminuindo sua taxa de crescimento, podendo levar a um retardo no crescimento intrauterino [25]. Como resultado de uma isquemia intestinal em períodos de hipóxia, ocorre hiperperistaltismo transitório...

RESUMO

Background: The rhinosporidiosis is caused by Rhinosporidium seeberi, an aquatic parasite that occur in flooded regions. The disease can affect several species, including horses. In Brazil, there are few reported cases and the mortality rate is low, thus its epidemiological importance is related to its zoonotic aspects. The transmission of Rhinosporidium seeberi occurs via contaminated water or soil and subsequent infection through mucosal injury where a granulomatous lesion is developed. In horses, nasal mucosa is the most affected area and laryngeal affection is rare. The aim of this work is to describe a case of nasal and laryngeal rhinosporidiosis in a horse, focusing on diagnosis and therapeutics. Case: A 07-year-old crossbreed male was referred to the Veterinary Clinics Hospital (HCV) of UFPel, RS, with clinical history of cough and nasal discharge. In the clinical examination, the patient showed a proliferative mass near the nasal septum located medially in the left nostril, tracheal rales and respiratory distress. Hematologic findings were in agreement with the reference values for the species. The tumor was removed with the animal standing using local anesthesia and sedation and the fragments were fixed in 10% formaldehyde solution and sent for histopathological examination. Fifteen days later, the patient was referred for further evaluation in the HCV, showing the...(AU)
