Deep anterior lamellar keratoplasty (DALK) as a treatment of a deep stromal ulcer in a dog: case report / Ceratoplastia lamelar anterior profunda(DALK) como tratamento de úlcera estromal profunda em cão: relato de caso

Characterized by the rupture of the corneal epithelium, corneal ulcers threaten ocular integrity, with multifactorial development, such as decreased protection and excessive abrasion applied to the corneal surface. Keratoplasty restores the corneal anatomy, removing the inflamed or infected tissues, in order to promote visual acuity. The technique of deep anterior lamellar keratoplasty (DALK) selectively removes the diseased layers of the cornea, keeping the Descemet membrane and endothelium healthy, reducing the risk of rejection, aimed at tissue recovery. In the present report, a canine, from the Shih Tzu breed, a female, that has not been castrated, 2 years and 6 months old, was treated, she had a history of ocular discomfort and mucous secretion in both eyes. In the ophthalmic examination, keratoconjunctivitis sicca was found in the left eye and ectopic cilia was found in both eyes. With the aid of a fluorescein test, the presence of a deep stromal ulcer affecting the right eye was confirmed. The patient underwent ectopic cilia removal using the wedge resection technique and an allogeneic corneal transplantation using DALK, with only the diseased epithelium and stroma being replaced, reducing the risk of rejection and failures related to surgery. 90 days after the procedure, there was no reaction to the graft, there was complete epithelial repair and maintenance of

Caracterizada pela ruptura do epitélio corneano, as úlceras de córnea ameaçam a integridade ocular, tendo desenvolvimento multifatorial, como a diminuição da proteção e o excesso de abrasão aplicado na superfície da córnea. A ceratoplastia restaura a anatomia corneana, removendo tecidos inflamados ou infectados, com objetivo de promover acuidade visual. A técnica de ceratoplastia lamelar anterior profunda (DALK -deep anterior lamelar keratoplasty) remove seletivamente as camadas doentes da córnea, mantendoa membrana de Descemet e endotélio saudáveis, reduzindo o risco de rejeição, visando recuperação tecidual. No presente relato, um canino, raça Shih Tzu, fêmea não castrada, 2 anos e 6 meses de idade, foi atendido com histórico de desconforto ocular e secreção mucosa em ambos os olhos. No exame oftálmico constatou-se ceratoconjuntivite seca no olho esquerdo e cílios ectópicos em ambos os olhos. Com auxílio do teste de fluoresceína, confirmou-se a presença de úlcera estromal profunda acometendo o olho direito. O paciente foi submetido a remoção dos cílios ectópicos pela técnica de secção em cunha e ao transplante de córnea alógena utilizando a DALK, sendo substituído apenas o epitélio e estroma doentes, reduzindo o risco de rejeição e falhas relacionadas a cirurgia. Após 90 dias do procedimento, constatou-se ausência de reação ao enxerto, completa reparação epitelial e manutenção da função visual com discreta opacidade corneana.

Steinmann pins and polymethylmethacrylate repair of fourth lumbar vertebral fracture and dorsocranial luxation in puppy

Background: Acute spinal traumas can lead to irreversible damage associated with vascular and inflammatory changes in neural tissue. Since spine and spinal cord traumas have an unfavorable prognosis in small animals, and reports of the use of Steinmann pins and polymethylmethacrylate repair of lumbar vertebra fracture-luxation in puppies are rare in the literature, the present paper aimed to report the surgical treatment of transversal fracture through the body of the fourth lumbar vertebra, with dorsocranial displacement of the caudal fragment by using Steinmann pins and polymethylmethacrylate in a 7-month-old Labrador Retriever male dog. Case: A 7-month-old intact male Labrador Retriever dog, weighing 24.0 kg was attended at School Veterinary Hospital with a history of hit by car and paraplegia of the hind limbs. On neurological examination was observed no proprioception and no deep pain sensitivity on the both pelvic limbs. The lumbar spinal palpation showed intense pain, and the motor function and patellar reflexes were reduced. The values of haematological and biochemical analysis remained within the reference values for the species. Radiographs revealed a transversal fracture through the body of the fourth lumbar vertebra, with dorsocranial displacement of the caudal fragment, and was decided to perform a surgical treatment by open reduction and internal fixation of the fracture. The dog was positioned in ventral recumbency for surgery, and a dorsal midline incision was made from the second lumbar vertebra to the sixth lumbar vertebra. Two crossed 1.5 mm Kirschner wires were placed through the caudal articular facets of the fourth lumbar vertebra to provide initial stability...

Infiltrative lipoma causing lumbar nerve root compression in a dog

Background: Lipomas are benign soft tissue mesenchymal neoplasms composed of adipose cells and are usually foundin the subcutaneous tissue. Occasionally, lipomas may invade muscles or grow between them, in which case they arecharacterized as infiltrative lipomas. Clinical signs resulting from an intermuscular lipoma compressing peripheral nervesare rarely encountered in dogs. This case report aims to describe the neurological signs, diagnosis, and clinical evaluationof a dog diagnosed with infiltrative lipoma compressing a lumbar spinal nerve root.Case: A 12-year-old neutered male Fox Paulistinha, weighing 10.5 kg, was presented with difficulties in walking for thepast 15 days with no previous history of trauma. On physical examination, the presence of three cutaneous nodules wasnoted in the ventral thoracic region, with onset of one year and slow and progressive growth. A cytological evaluation ofthe nodules was performed, and lipoma was diagnosed. At the neurological examination, the patient presented ambulatoryparaparesis with marked motor deficit and atrophy of the quadriceps muscles of the left pelvic limb. Conscious proprioceptive deficit, the absence of patellar reflex, and diminished withdrawal reflex were observed in the left hind limb, in additionto diffuse pain on epaxial palpation of the lumbar region. Electroneuromyography showed increased insertion activity inthe left gastrocnemius muscle and moderate spontaneous activity (fibrillation). Persistence of 10% was observed in theF-wave study of the left tibial nerve. These findings indicate partial involvement of the roots of the left sciatic-tibial nerve.Magnetic resonance imaging (MRI) showed the presence of a mass measuring 3.18 × 1.04 × 1.4 cm, interspersed withthe paravertebral muscles, and located adjacent to the L2 and L3 spinous processes...

Tumor venéreo transmissível cutâneo sem envolvimento genital em cão macho / Transmissible cutaneous venereal tumor without genital involvement in a male dog / Cutánea tumor venéreo transmisible sin la participación genital en perro macho

O tumor venéreo transmissível (TVT) trata-se de uma neoplasia de células redondas, transmitida a partir do transplante de células neoplásicas, altamente contagiosa, que afeta principalmente a genitália externa de caninos e também regiões extragenitais. A forma cutânea geralmente acomete a região de face e membros, secundária a um foco genital primário de forma simultânea. Relata-se um caso de TVT cutâneo sem envolvimento genital em um cão macho sem padrão de raça definida (SPRD), quatro anos de idade, semidomiciliado, com queixa principal de aparecimento de lesão única, de caráter nodular, friável, ulcerada com exsudação sanguinolenta na região cervical lateral. Foi realizada punção aspirativa com agulha fina para avaliação citológica, que demostrou predomínio de células redondas monomórficas, com vacuolização citoplasmática, citoplasma basofílico e escasso, além de núcleos ovais e centralizados, citologia esta compatível com TVT. Adotou-se o protocolo de tratamento quimioterápico com sulfato de vincristina 0,025 mg/kg a cada sete dias, com regressão completa do tumor após seis semanas. O envolvimento do tecido cutâneo sem acometimento venéreo é raro, e diante disso o TVT pode ser incluído como diagnóstico diferencial de lesões nodulares ou tumorais isoladas.(AU)

The transmissible venereal tumor (TVT) is a round cells tumor, transmitted from the highly contagious neoplastic cell transplantation, which mainly affects the external genitalia of dogs and also extragenital regions. The cutaneous form usually affects the region of the face and limbs, secondary to a primary genital focus simultaneously. A case of cutaneous TVT without genital involvement is reported in a four-year-old male, without racial standard set, half-domiciled, with a major complaint of a nodular, friable and ulcerated lesion with bloody exudation in the lateral cervical region. Fine needle aspiration was performed for cytological evaluation, and presented a monomorphic round cell population, with cytoplasmic vacuolization, basophilic and scarce cytoplasm, oval and centralized nuclei. The cytology evaluation was compatible with TVT. The chemotherapy protocol was adopted with vincristine sulphate at 0.025 mg/kg every 7 days. Complete regression of the tumor mass was observed after six weeks. Involvement of the cutaneous tissue without venereal involvement is uncommon, and there after the TVT is included as a differential diagnosis of isolated nodular cutaneous lesions.(AU)
