Background: Squamous cell carcinoma (SCC) is one of the most common cutaneous neoplasms found in equine breeding.The main cause is still unknown, based on predisposing factors such as excessive exposure to ultraviolet rays, advancedage, depigmented skin and viral or parasitic agents. There is currently a range of possibilities for the treatment of SCC.The choice of the ideal treatment changes according to the location, evolution and size of the tumor, economic costs andavailability of material. The present case report aims to report the case of a Campeiro breed, diagnosed with SCC in theleft lacrimal gland region and to evaluate the action of vincristine sulfate as intralesional chemotherapy.Case: A 30-year-old stallion of the Campeiro perlino coat it was attended in the sector of Clinic and Surgery of LargeAnimals, at the Federal University of Santa Catarina - Curitibanos campus. Physical examination revealed an alert anddocile temperament, with no considerable physiological changes. In the evaluation of the left eye, it was observed a massof 2x2 cm rosacea, with granular and ulcerated appearance, it was detected in the portion of the medial corner of the eye,and the lacrimal gland cannot be macroscopically delimited. Also it was detected a moderate mucopurulent secretion.The mass was collected through fine-needle aspiration (FNA) and puncture without aspiration of contents found in thethird eyelid region for cytological analysis, and a malignant epithelial cell neoplasia associated with septic suppurativeinflammation was observed, suggestive of SCC. After the laboratory results analyzed, 0.25 mL of intralesional vincristinesulfate (Vincizina®) with 20x06 needle was applied in the base of the tumor mass as treatment. After 24 days of the firstand only application of the antineoplastic, treatment success was remarkable, with a macroscopic involution...

The aim of this study was to describe the modified Schirmer tear test (mSTT), intraocular pressure (IOP) by rebound tonometry and palpebral fissure length (PFL) in blue-fronted Amazon parrots (Amazona aestiva). Thirty-five healthy adult animals from a conservation breeding center in Brazil were used in this study. Modified Schirmer tear test, rebound tonometry and PFL measurements were performed in both eyes, with birds under physical restraint. Mean mSTT was 6.2±0.1mm/min and mean IOP was 6.4±0.1mmHg, while PFL was 10.1±0.1mm. A moderate correlation was seen between mSTT and PFL for OD (ρ=0.14) and OS (ρ=0.20). The results provide ophthalmic tests reference values for A. aestiva.(AU)


O objetivo deste estudo foi descrever o teste lacrimal de Schirmer modificado (TLSm), a pressão intraocular (PIO) pela tonometria de rebote e o comprimento da fissura palpebral (FP) do papagaio-verdadeiro (Amazona aestiva). Foram avaliados 35 papagaios adultos e saudáveis, provenientes de um Criadouro Conservacionista do Brasil. Após avaliação clínica e laboratorial, as aves foram fisicamente contidas para aferição, em ambos os olhos, do TLSm, da PIO pela tonometria de rebote e do comprimento da FP utilizando-se um paquímetro digital. Valor médio do TLSm foi 6.2±0.1mm/min e da PIO foi 6.4±0.1 mmHg, enquanto a aferição da FP foi 10.1±0.1mm. Uma correlação moderada foi observada entre TLSm e a FP para olho direito (OD) (ρ=0.14) e olho esquerdo (OE) (ρ=0.20). Os resultados podem servir como valores de referência para testes oftálmicos para A. aestiva.(AU)
