Hérnia perineal em cães / Perineal hernia in dogs

Background: Perineal hernia is a serious disease characterized by weakening or atrophy and separation of the muscles andfasciae of the perineal musculature, followed by the caudal displacement of pelvic and abdominal organs to the perineumregion. Treatment is invariably surgical and several approaches have been proposed, but complication and recurrence ratesremain high. This study aimed to evaluate 120 cases of perineal hernia treated at the Veterinary Hospital of Uberaba (HVU)from 2005 to 2020, addressing the clinical and surgical aspects and the postoperative period, seeking to identify the mostrelevant factors to improve care and treatment of future patients affected by this disease.Materials, Methods & Results: The medical records of dogs with a definitive diagnosis of perineal hernia were collected.The prevalence of perineal hernia was calculated. Data were obtained regarding sex, being castrated or not, age, bodymass, race, clinical signs, affected side, possibility of hernia reduction, treatments used, associated pathologies. Of the 120cases, only 69 underwent surgery at the HVU and from these cases data were obtained regarding hernia content, surgicaltechniques, surgical wires used, recurrences and postoperative complications. Fishers exact test was applied to assess theinfluence of the type of surgical treatment and surgical thread on the occurrence of complications and recurrences. Perineal hernia was the second most frequently observed hernia. Mixed breed, male, non-neutered and geriatric dogs were themost affected. The most frequently observed clinical signs were related to the digestive and urinary tract, consistent withthe most commonly found hernia contents (bladder, prostate and rectum). The simple herniorrhaphy technique was themost used and showed a high number of complications. The second most used technique was...(AU)

Mesotelioma de túnica vaginal en paciente con hidrocele rápidamente progresivo / Mesothelioma of the Tunica Vaginalis in a Patient with Rapidly Progressive Hydrocele

El mesotelioma es una entidad poco común y agresiva que compromete el mesotelio, involucrando así los diferentes órganos cubiertos por membranas serosas. El mesotelioma de túnica vaginal es una neoplasia muy rara, con un cuadro clínico poco específico y de difícil diagnóstico con las técnicas imagenológicas actuales. Presentamos el caso de un paciente con hidrocele rápidamente progresivo que fue llevado a hidrocelectomía. Se realizó un diagnóstico histopatológico de mesotelioma epitelial maligno de túnica vaginal que requirió orquidectomía radical, hemiescrotomectomía y linfadenectomía retroperitoneal. A un año de seguimiento, el paciente no tiene evidencia de la enfermedad.

Mesothelioma is an uncommon and aggressive entity that compromises the mesothelium, thus involving the different organs covered by serous membranes. The mesothelioma of the tunica vaginalis is a very rare neoplasm, with a non-specific clinical picture and difficult diagnosis with current imaging techniques. We report the case of a patient with rapidly progressive hydrocele who was taken to hydrocelectomy. A histopathological diagnosis of epithelial mesothelioma of the tunica vaginalis was made, which required radical orchiectomy, hemiscrotectomy and retroperitoneal lymphadenectomy. At one year of follow-up, the patient has no evidence of the disease.

Hemangioma Cavernoso Paratesticular da Túnica Vaginal: um Relato de Caso / Paratesticular Cavernous Hemangioma of the Tunica Vaginalis: A Case Report

Os hemangiomas são tumores benignos, e raramente podem se apresentar no tecido paratesticular. Sua fisiopatologia ainda é desconhecida, e são poucos os relatos de caso dessa doença, que atinge mais frequentemente pacientes jovens. Apesar de benigna, pode mimetizar tumores malignos do testículo, sendo na maioria das vezes indicada abordagem invasiva para o diagnóstico. Apresentamos o relato de caso de um paciente com nódulo testicular. No decorrer da investigação, suspeitou-se de neoplasia maligna, sendo realizada orquiectomia com posterior análise patológica e diagnóstico de hemangioma paratesticular da túnica vaginal

Hemangiomas are benign tumors, and can rarely occur in the paratesticular tissue. Its etiology is still unkown, and there are few case reports of this disease, which affects younger patients more often. Although benign, it can mimic malignant tumors of the testis, and an invasive approach to diagnosis is indicated. We present the case of a young patient who underwent to orchiectomy for a testicular nodule. Posterior pathological analysis presented as paratesticular hemangioma of the tunica vaginalis

Mesotelioma bem diferenciado (benigno) de túnica vaginal: relato de um caso e revisão da literatura / Well-differentiated (benign) mesothelioma of the tunica vaginalis: report of a case and literature review

Mesoteliomas são tumores oriundos das células mesoteliais da pleura, peritônio, pericárdio ou túnica vaginal, sendo a exposição prolongada ao asbesto o principal fator de risco. Neoplasias mesoteliais benignas da região paratesticular são raras. Relata-se um caso de Mesotelioma de Túnica Vaginal associado à hidrocele, destacando a utilidade da ecografia na avaliação das massas escrotais (AU)

Mesotheliomas are tumors originating from the mesothelial cells of the pleura, peritoneum, pericardium or tunica vaginalis, with prolonged exposure to asbestos the main risk factor. Benign mesothelial neoplasms of the paratesticular region are rare. Here we report a case of tunica vaginalis mesothelioma associated with hydrocele, highlighting the usefulness of ultrasound in the evaluation of scrotal masses (AU)

Use of fresh autogenous vaginal tunic in the experimental lamellar keratoplasty in dogs (Canis familiaris, LINNAEUS, 1758) / Emprego da túnica vaginal autógena, a fresco, em ceratoplastia lamelar experimental em cães (Canis familiaris, LINNAEUS, 1758)

Autogenous vaginal tunics have been researched in lamellar keratoplasty in dogs using fresh autogenous grafts in the repair of superficial keratectomies. Fourteen dogs have been used for the evaluation at the early, intermediary and late postoperative periods. Photophobia, blepharospasm, ocular discharge, edema, neovascularization and pigmentation have been observed. The results have showed that the original procedure is useful for the repair of corneas after superficial keratectomies.

Empregou-se a túnica vaginal autógena, a fresco, na ceratoplastia lamelar em cães. Foram utilizados 14 cães, a serem avaliados nos períodos iniciais, intermediários e tardios. Fotofobia, blefarospasmo, descarga ocular, edema, neovascularização e pigmentação corneanas foram observados. Os resultados mostraram ser a técnica factível de utilização na reparação corneana após ceratectomias superficiais.
