According to our research, this is the first case described in the literature of spontaneous intracranial epidural hematoma secondary to the use of Xarelto ® . Spontaneous intracranial epidural hematomas are rarely described in the literature. They are associated with infectious diseases of the skull, coagulation disorders, vascular malformations of the dura mater and metastasis to the skull. Long-term post-marketing monitoring and independent reports will probably detect the full spectrum of hemorrhagic complications of the use of rivaroxaban.
The donkey jack sex glands are larger than stallions, responsible for producing most part of seminal plasma and the second fraction of ejaculate, along with epididymis tail. Plugged ampullae occur by sperm accumulation obstructing the lumen, inducing decrease in sperm quality and may cause azoospermia. In this study, a Pêga breed donkey jack, aging 4 years, was evaluated for breeding soundness evaluation due to a sudden decrease in semen parameters and low fertility rates. Palpation, measurements, and ultrasound examinations of testicles were normal; however, rectal palpation revealed increased volume of ampullae and deferent duct, and the transrectal ultrasonography revealed distended ampullae with hyperechogenic material in the ampullae lumen. After ampullae massage, the semen was collected with artificial vagina for evaluation, resulting in high concentrated semen (1.46 Â 10 9 spermatozoa/mL) with low motility (5%), 14% of major defects, and 57% of minor defects. Plugged ampullae were suggested, and the treatment was performed by ampullae massage per rectum and three consecutive semen collections associated with the parenteral use of oxytocin 20 IU iv, aiming to discharge the semen accumulation. Daily regimen of semen collection was recommended during 10 days, and after this time, semen was collected at least three times a week. The semen parameters restored to normal (80% motility) after 30 days. The donkey jack returned to the breeding season with a regimen of 3 days a week of semen collection.
RESUMOMastose ou displasia cística mamária é uma mastopatia rara, podendo estar associada a níveis elevados de estrogênio. O presente trabalho teve por objetivo relatar o caso de um canino, macho, da raça Poodle, com trezes anos de idade, apresentando aumento de volume em mamas. À anamnese o proprietário informou que o animal não era castrado e ao exame clínico observou-se ausência dos testículos na bolsa escrotal e que o aumento de volume nas mamas era de conformação cística. Durante a palpação abdominal verificou-se presença de uma massa circunscrita com consistência firme e ao exame ultrassonográfico foi identificada uma estrutura compatível com neoformação intra-abdominal. Procedeuse a laparotomia exploratória, possibilitando observar que um dos testículos estava aumentado de volume, enquanto o contralateral apresentava volume reduzido, realizando-se orquiectomia bilateral. Posteriormente realizou-se exame histopatológico das peças cirúrgicas, onde se diagnosticou seminoma com áreas de sertolioma no testículo aumentado de tamanho. Desta forma, a descrição deste caso possui relevância clínica, devido à baixa frequência de ocorrência de mastose associada a neoplasia testicular em cão criptorquida, salientando o tratamento realizado com a retirada do testículo por se tratar de uma patologia hormônio dependente. PALAVRAS-CHAVE: displasia mamária cística, hiperestrogenismo, seminoma, sertolioma
MASTOSIS ASSOCIATED WITH TESTICULAR TUMOR IN A CANINE WITH CRYOTORCHIDISMABSTRACT Mastosis or cystic mammary dysplasia, is a rare disease and may be associated to high levels of estrogen. This study aimed to report the case of a canine, male, Poodle, with thirteen years of age, with an increase of mammary gland size. According to the owner, the animal was not castrated and clinical examination revealed absence of testicles in the scrotum and the increase of mammary gland size exhibit cystic conformation. During abdominal palpation there was the presence of a circumscribed mass with firm consistency and ultrasound examination showed a
