Utilização da ozonioterapia como tratamento da endometrite em égua / Use of ozone therapy as endometritis treatment in mare

Conformações perineais inadequadas estão frequentemente associadas à pneumovagina, predispondo animais a processos inflamatórios vaginais e uterinos. Dentre as patologias reprodutivas que acometem éguas, a endometrite é a que ocorre com maior frequência, com forte impacto negativo sobre os índices reprodutivos de um criatório. Para essa afecção, a ozonioterapia se apresenta como tratamento em potencial. Assim, este estudo objetiva relatar um caso de endometrite em égua Quarto de Milha, multípara, de 17 anos de idade, atendida no Hospital Veterinário Sylvio Barbosa Cardoso, da Universidade Estadual de Ceará. Durante a avaliação ginecológica, observou-se alterações na conformação vulvar e teste de Windsucker positivo, indicando pneumovagina. Foram coletadas amostras endometriais para exames laboratoriais, os quais apresentaram citologia com contagem de neutrófilos polimorfonucleares ≥30% e cultura negativa para fungos e bactérias. O exame histopatológico revelou fibrose intersticial endometrial crônica acentuada. Diante do diagnóstico de endometrite, iniciou-se o tratamento com lavagem uterina usando solução ringer lactato ozonizada, seguido por insuflação uterina com ozônio. O animal foi submetido à técnica cirúrgica de Caslick para correção da má conformação vulvar. Após o tratamento, a égua foi inseminada, resultando na coleta de dois embriões viáveis. Diante do exposto, o caso reforça a efetividade da ozonioterapia associada à Caslick para o tratamento de endometrite em éguas.

Dysfunctional perineal conformations are often associated with pneumovagina, predisposing animals to vaginal and uterine inflammatory processes. Among the reproductive pathologies that affect mares, endometritis is the most frequent, with a strong negative impact on the reproductive indices of a farm. For this condition, ozone therapy presents itself as a potential treatment. The study aimed to report a case of endometritis in a 17-year-old multiparous quarter-mile mare, which was attended at the Veterinary Hospital Sylvio Barbosa Cardoso located in the State University of Ceará. During the gynecological evaluation, changes in vulvar conformation and a positive Windsucker test were observed, indicating pneumovagina. Endometrial samples were collected for laboratory exams, resulting in cytology with polymorphonuclear neutrophil count ≥30% and negative culture for fungi and bacteria. The histopathological examination revealed severe chronic endometrial interstitial fibrosis. Regarding the diagnosis of endometritis, the treatment with uterine lavage using ozonated ringer lactate solution was initiated followed by uterine insufflation with ozone. The animal was submitted to Caslick's surgical technique to correct the vulvar malformation. After treatment, the mare was inseminated, resulting in the collection of two viable embryos. In view of the above, the case reinforces the effectiveness of ozone therapy associated with Caslick`s technique for endometritis treatment in mares.

Achados clínicos, histopatológicos, laboratoriais e imagens de adenocarcinoma prostático em cães / Clinical, laboratory, histopathological and image findings of prostatic adenocarcinoma in dog

Prostate neoplasms are the main reproductive disorders affecting neutered dogs, being the adenocarcinoma the most common and developing signs of urinary and/or gastrointestinal tract. This tumor develops spontaneously in dogs, being malignant, very invasive and unresponsive to castration. Due the recent increase in reports and a high interference in the animals' quality of life, the objective of this study was to report a case of prostatic adenocarcinoma in an eight-year-old SRD dog with metastasis in bladder, peritoneum and mesentery. The animal presented dehydration, fever, difficulty for walking, severe pain, abdominal enlargement, apathy, hyporexia, hypodipsia and tenesmus. Rectal examination, identified a firm mass and incongruous in prostatic membrane. Two months before an orchiectomy was performed due a prostatomegaly. At the time, an ultrasound identified irregular prostate with cavity formations, spleen with hypoechogenic formation and bladder with hyperechogenic formation attached to the wall. Radiography was requested and fecaloma was observed. Thus, enterotomy and prostatectomy were required. In surgery, nodulations were identified in mesentery, peritoneum and spleen, in addition to a hemorrhagic focus and a palpable mass in the bladder. The prostate was attached to bone tissue, making the removal impossible. The animal was euthanized and prostatic histopathology identified acinar adenocarcinoma. Histological samples of peritoneum, mesentery and bladder presented metastasis. The treatment of this conditionis not feasible with a delayed diagnosis due to its high aggressiveness and metastatic capacity. Such report demonstrates the importance of digital rectal examination and ultrasound exams, even in castrated animals for a nearly diagnosis of these neoplasms.

Leydigocitoma canino: aspectos ultrassonográficos, citológicos e histopatológicos / Canine Leydigocitoma: ultrasonographic, cytological and histopathological aspects

In non-neutered dogs, the testis is the second most common site for development of neoplasms, frequently occurring in elderly animals and with orchiectomy as main treatment. Regarding the great relevance of testicular disorders and the importance of accurate diagnoses, this study aims to report a case of canine leydigocytoma at the Veterinary Hospital in the State University of Ceará. The 10-years-old non-neutered Pitbull-breed animal was attended presenting hematuria and, physical examination showed a bilateral nodular formation in testicles in addition to an enlarged prostate. In ultrasonographic examination, the prostate was enlarged, presenting irregular shape and heterogeneous echotexture. These changes indicate the presence of prostatic hyperplasia. Both testicles presented well-defined hypoechogenic regions with evident marginal and internal vascularization, which indicate neoplastic neoformation. In cytology, a hypercellular epithelial sample was observed with cellular modifications suggestive of interstitial cell neoplasia. In the lab, macroscopically, the testis showed multiple soft, well-defined, white-colored to brownish nodules. Histopathology revealed neoplastic proliferation of Leydig cells, sustained by moderate fibrovascular stroma, with degenerated adjacent parenchyma and without signs of malignancy. Four months after orchiectomy, the prostate turned to normal dimensions, with no further ultrasonographic changes. This case reinforces the importance of bilateral orchiectomy and ultrasound for prostatic abnormalities and testicular neoplasms. The association of these conditions is not commonly described in the literature, being an important contribution in this regard.

Sertolioma em cão com testículo ectópico: achados clínicos, hematológicos, ultrassonográficos e histopatológicos / Sertolioma in a dog with ectopic testis: clinical, hematological, ultrasonographic and histopathological findings

Sertoliomas are among the most common testicular neoplasms in dogs, and one of its main risk factors is disorders in the process of testicular dehiscence, which causes the retention of one or both testicles out of the scrotum. Thus, the present study aims to report a case of a tumor of Sertoli cells (Sertolioma) in an ectopic testicle in the right inguinal region in an SRD dog at Hospital Veterinário Sylvio Barbosa Cardoso, of the State University of Ceará. A 5-year-old, non-neutered male canine, SRD, weighing 18 kg, came to attend an increase in the right inguinal region. On physical examination, the presence of a firm mass located in the subcutaneous tissue in the right inguinal region was identified, in addition to absence of right testicle in the scrotal pouch and a left testicle decreased in size and with softened consistency. In ultrasound evaluation, the left testicle was located in usual topography, with regular contours and standard echogenicity. In the right inguinal region, an echogenic image of heterogeneous echotexture was perceived, indicating the presence of an ectopic testis. After bilateral orchiectomy, both parts were referred for histopathological analysis, presenting a benign Sertolioma in the ectopic testis and testicular degeneration in the topical testicle was reported. The case reinforces the importance of bilateral orchiectomy and ultrasound for abdominal and gonadal evaluation of non-neutered males.
