Exploring canine mast cell tumors: An investigation into demographic characteri...

Mast cell tumors (MCT) are among the most common neoplasia in dogs, representing up to 21 % of skin tumors. However, etiology and risk factors for its development remain unclear. This study aimed to reduce this knowledge gap by comprehensively analyzing 905 MCT cases diagnosed in Portugal between 2019 and 2021, using descriptive and inferential analyses. Most tumors affected the skin, with 69.9 % and 21.2 % cla...

A One pathology multicentre Portuguese approach to thyroid tumours of dogs and ...

Thyroid tumours are the most common endocrine tumours of dogs and cats. Feline thyroid tumours are essentially functional adenomas curable with thyroidectomy, whereas most canine thyroid tumours are non-functional carcinomas either unresectable or recurrent within two years in up 50%. The oncobiology of these tumours remains unclear, but investigating this aspect could contribute to the development of targeted ...

Pluronic® F127 Hydrogel Containing Silver Nanoparticles in Skin Burn Regenerati...

Presently, skin burns are considered one of the main public health problems and lack therapeutic options. In recent years, silver nanoparticles (AgNPs) have been widely studied, playing an increasingly important role in wound healing due to their antibacterial activity. This work is focused on the production and characterization of AgNPs loaded in a Pluronic® F127 hydrogel, as well as assessing its antimicrobia...

Contributo ao estudo dos mastocitomas dos cães

Cross Species Analysis and Comparison of Tumors in Dogs and Cats, by Age, Sex, ...

The animal cancer burden is essential for the translational value of companion animals in comparative oncology. The present work aims to describe, analyze, and compare frequencies and associations of tumors in dogs and cats based on the Animal Cancer Registry created by Vet-OncoNet. With 9079 registries, regarding 2019 and 2020, 81% (n = 7355) belonged to dogs. In comparison, cats have a general one-year right ...

Biological Thermal Performance of Organic and Inorganic Aerogels as Patches for...

Aerogels are materials with unique properties, among which are low density and thermal conductivity. They are also known for their exquisite biocompatibility and biodegradability. All these features make them attractive for biomedical applications, such as their potential use in photothermal therapy (PTT). This technique is, yet, still associated with undesirable effects on surrounding tissues which emphasizes ...

Vet-OncoNet: Malignancy Analysis of Neoplasms in Dogs and Cats

Analysis of canine and feline tumor malignancy data can help clinicians identify high-risk patients and make more accurate decisions. Based on a sample of 16,272 cancer records, including 3266 cats and 13,006 dogs, collected from January 2019 to December 2021 in the Vet-OncoNet Network database, this study aimed to compare the tumor malignancy profile between cats and dogs, considering animal-related factors (s...

Caso clínico: amiloidose subcutânea num gato

Um gato macho, de 14 anos, apresentou-se para consulta devido a duas massas subcutâneas não dolorosas presentes nas regiões inguinais esquerda e direita. Após excisão cirúrgica a análise histopatológica revelou a presença de um material amorfo acelular eosinofílico no tecido subcutâneo, rodeado por um infiltrado inflamatório rico em linfócitos, plasmócitos e células gigantes multinucleadas. Com base nas alteraç...

National survey of cat tumors in 2019: a retrospective study

Cancer is one of the most common causes of death in cats. Besides its clinical importance, small animals with spontaneous tumours are attractive comparative models for Oncologic studies. Cancer registries are important to provide increased information, which can be used in epidemiological studies and prophylactic and treatment strategies. The aim of this study was to characterize the current distribution of fel...

Caso clínico: granuloma reparativo de células gigantes

Um gato, fêmea, de 8 anos, apresentou-se para consulta devido à presença de um nódulo de crescimento rápido na base da unha. A lesão foi extirpada cirurgicamente e enviada para histopatologia. Na análise histopatológica observou-se a presença de um infiltrado inflamatório dérmico rico em células gigantes multinucleadas que focalmente rodeavam restos de queratina livre, num estroma reativo com regiões de metapla...
