Item Avaliação de nódulos tireoidianos por Elastografia: comparação de suas características com a punção aspirativa por agulha fina de tireóide(Universidade Brasil, 2020) Bernardes, Antônio José de Macedo; Fávero, Priscila Pereira; Pires, Ivan Luiz PedrosoIntroduction: Classically, thyroid nodules are initially evaluated by ultrasonography in Mode B. Despite being sensitive for the diagnosis of NT, it does not take into account the stiffness of the nodule, an important characteristic that is related to its malignancy. In this sense, elastography has been used as an instrument to assist in the diagnosis of thyroid nodules. With this in mind, the aim of the present study is to qualitatively assess the performance of manual pressure elastography in the differential diagnosis of malignant and benign thyroid nodules in adults. Method: This is a prospective, observational study, which included patients who had thyroid nodules and required fine needle aspiration (FNAB). The elastography was obtained in real time from the US in Mode B. The percentage of the nodule's rigid area was calculated using the ImageJ software. Results: The study included 41 patients, 87.8% female. Age ranged from 18 to 75 years, with an average of 46.4 years (SD: 13.57). Most of the nodules were classified as TI-RADS 3, 53.7%. As for the Bethesda classification, 82.9% of the sample was classified as Bethesda 2 (benign nodule). The percentage of rigid area (% AR) ranged from 3% to 73%, with an average of 28.73% (SD: 18.15). Highly suspicious nodules from the TI-RADS classification had a higher AR% (51.6%). Regarding cytological analysis, nodules characterized as benign had an average AR% of 24.23% (SD: 13.66), while malignant ones of 55% (SD: 19.94), a difference of 30.77% , which proved to be statistically significant (p <0.001). Conclusion: The quantitative evaluation of Strain type elastography based on the% AR evaluation proved to be useful to discriminate between benign and malignant nodules and is presented as a tool that can complement the assessment of thyroid nodules.Item A importância do ultrassom na Medicina Veterinária para pequenos animais(Universidade Brasil, 2023) Rossini, Cristiane Beltoni; Justo, FabianaItem Leucemia linfocitica crônica em cães: revisão de literatura e relato de caso(Universidade Brasil, 2018) Cruppi, Clara Caroline; Jark, Paulo CésarItem Ultrassonografia gestacional em cadelas(Universidade Brasil, 2017) Rubia, Maria Carolina; Zangirolami Filho, DarcioItem DVG - Síndrome da dilatação vólvulo gástrica intestinal em cães: estudo de caso clínico(Universidade Brasil, 2021) Campos, Karen Cristiane Moreira; Teixeira, Tarso FelipeA 17-year-old male Dachshund (Teckel) dog was treated at a private veterinary clinic, with episodes of emesis and increased volume in the abdominal region. The presence of hyposegmented neutrophils and neutrophils with toxic granulations was verified on the blood count, after abdominal ultrasound, many gases and a possible gastric dilation with volvo (VgD) were observed which was proven by X-ray, so the patient was immediately submitted to the surgical procedure, which occurred without complications, remained stable in the postoperative period, with parameters within normal limits for species and age. However, after a few hours, the animal began a neurological picture with vocalization and nystagmus, remaining most of the time in lateral decubitus, with cyanotic mucous membranes and vasculitis of limbs, even having received all the necessary care, such as oxygen therapy, continuous infusion with glucose, supportive fluid therapy, the animal did not resist, dying the day after the surgical procedure. Gastric Ovvulus Dilation is a pathology considered severe, whose chance of survival of the patient is due to the rapid intervention to correct the case.
