Laminitis in horses is often associated with endocrine disorders, especially the pituitary pars intermedia dysfunction (PPID) in older animals. Morphologic exams of the laminar tissue of the hoof were performed in two horses with suspected PPID, with no clinical signs of laminitis. Changes compatible with laminitis of endocrine origin were observed, such as rounding of the nuclei of the basal cells, thinning and stretching of the secondary epidermal laminae and tissue proliferation. PPID horses with no clinical signs of laminitis may be affected by lesions of the laminar tissue of the hoof that compromise the integrity of the dermal-epidermal junction and may develop clinical symptoms of the disease. It has been suggested that the development stage of endocrine laminitis is longer, but further studies should be conducted to confirm it.Keywords: laminitis, metabolic syndrome, Cushing's syndrome, endocrine disorders, pituitary adenoma
RESUMO
A laminite em cavalos está frequentemente associada a distúrbios endócrinos, como a disfunção da pars intermedia da pituitária (PPID) em animais mais velhos. Exames morfológicos do tecido laminar do
Este artigo analisa a interpretação de Charles Melman sobre a colonização brasileira, apresentando sua leitura psicanalítica da clássica obra de Gilberto Freyre, Casa-grande e senzala, a partir do conceito lacaniano discurso do mestre. Nesse percurso teórico, introduzimos os principais elementos conceituais que sustentaram a interpretação de Melman sobre a cultura brasileira: verticalização discursiva, sexualidade colonial fundada no sadomasoquismo e proposição de uma psicopatologia da colonização. Posteriormente, discutimos o contraponto realizado por alguns psicanalistas, no que concerne a essa intepretação do Brasil, e contextualizamos as controvérsias entre psicanálise e colonização, apontando a declinologia francesa (hipótese do declínio da função paterna) como uma reedição do eurocentrismo colonial. Por fim, relançamos a pergunta que orienta a escrita deste trabalho: pode uma interpretação psicanalítica consistir em ato colonizador?Palavras-chave: psicanálise; interpretação; colonialidade; cultura brasileira.
Laryngeal hemiplegia is one of the most common upper airway affections in horses. Laringoplasty is indicated in high-performance animals, and when the only complaint is noisy breathing, ventriculectomy and cordectomy can be performed. This study aimed to establish a minimally invasive surgical approach to ventriculocordectomy in horses, through a videoendoscopic procedure. The technique was developed in two stages, the first one was a cadaveric study and the second one was in vivo, both using two flexible endoscopes. A bilateral ventriculocordectomy was performed in two cadavers, totaling the removal of four vocal cords. In the second stage, a left unilateral ventriculocordectomy was performed in three animals with laryngeal hemiplegia. The vocal cords were pulled by one of the endoscopes with 3.2mm grasping forceps, while the second equipment was used for the resection of vocal cords with a flexible electrode adapted for monopolar electrosurgery (electrocautery). The average time for removal of the vocal cords was 23±5 minutes. In the postoperative care, moderate inflammation around the surgical wound was observed, with complete healing in 21 days in one horse and 28 days in the other two. One animal presented exuberant granulation tissue on the surgical site. Other complications due to the tested technique were not noticed; therefore, it could be a less invasive option for ventriculocordectomy in horses. The developed technique proved to be effective for ventriculocordectomy execution in horses. The main advantages of this approach were reduced surgical time, shorter healing average time, no need for daily dressings and return to normal activities in a shorter period when compared to other surgical approaches. The limitation of the technique consists of the need for two endoscopes for its accomplishment. Further studies, with more animals, are needed to improve the technique.
