ABSTRACT
PURPOSE: To correlate optical coherence tomography (OCT) measurements with clinical parameters in idiopathic intracranial hypertension (IIH). METHODS: A cross-sectional study was conducted with 22 patients with IIH and 11 controls. All participants underwent comprehensive ophthalmological examination followed by spectral-domain OCT (SD-OCT) and standard automated perimetry using the 30-2 program of the Humphrey visual field analyzer. Correlations between ganglion cell complex (GCC) thickness and retinal nerve fiber layer (RNFL) thickness, as measured by SD-OCT, and clinical parameters were assessed using generalized estimating equations. RESULT: The mean age of the participants was 35.0 ± 10.83 years. The groups were similar regarding age, but were significantly different regarding sex and visual acuity (p=0.001 and p=0.038, respectively). The GCC was significantly thinner in the IIH group, with a mean of 90.535 ± 9.766 µm compared to 98.119 ± 6.988 µm for the controls (p=0.023). There was a significant association between GCC thickness and optic disc pallor (p=0.016) and between edema and visual acuity (p=0.037). No significant difference was found in RNFL thickness between patients and controls. CONCLUSION: The GCC was thinner in the patients with IIH compared to the controls, and there was an association between GCC and optic disc pallor. This might suggest a role for OCT parameters when the structural changes that occur in IIH are investigated, possibly guiding clinical decision making.
ABSTRACT
OBJETIVO: comparar o conhecimento e percepção em terapia nutricional (TN) de residentes de cirurgia e cirurgiões. MÉTODOS: foram aplicados dois questionários padronizados sobre conhecimentos, atitudes e condutas em TN de 50 médicos (35 residentes e 15 cirurgiões) de 12 áreas cirúrgicas distintas. Utilizando-se o teste exato de Fisher, com significância de 5% com p<0,05, foi comparada a proporção de acertos, de acordo com a percepção a respeito do assunto de cada grupo. RESULTADOS: mais de 80% não se sentiram seguros frente à TN e 46% negaram conhecimento de equipe multiprofissional de TN (EMTN). Houve maior percentual de acertos, dentre os residentes, nos itens: trauma operatório e sua influência nutricional no paciente (p=0,047); IMC normal (p=0,036); e TN no pré-operatório (p=0,007) e indicação da TN pré-cirúrgico no grupo que diz que interagem com EMTN (p=0,02). Dentre os cirurgiões: complicações da TN e TN em pacientes previamente desnutridos (p=0,044); e Métodos de avaliação nutricional no pré-operatório no grupo que diz que interagem com EMTN (p=0,01). CONCLUSÃO: há falhas na educação médica. Apenas 13,3% estavam seguros quanto à TN, sendo que os seus conhecimentos não justificaram tal confiança. Não houve diferenças entre os acertos dos confiantes e não confiantes em TN na maioria dos assuntos. Destacaram-se melhores resultados no grupo que afirmou ser assistido por alguma EMTN. Baseando-se nos resultados, a indicação de melhores programas médicos educacionais deve ser objetivo para esta universidade.
OBJECTIVE: To compare the knowledge of nutritional therapy (NT) of surgery residents and surgeons. METHODS: We applied two standardized questionnaires on knowledge, attitude and behavior regarding NT to 50 physicians (35 residents and 15 surgeons) of 12 different surgical areas. We compared the proportions of hits according to the perception on the subject of each group using the Fisher exact test, with 5% significance and p < 0.05. RESULTS: More than 80% did not feel safe regarding NT and 46% denied knowledge of the NT multidisciplinary team (NTMT). There was a higher percentage of correct answers among residents in the items: surgical trauma and its nutritional influence on the patient (p = 0.047); normal BMI (p = 0.036); preoperative NT (p = 0.007); and indication of preoperative NT in the group that referred that to interact with the NTMT (p = 0.02). Among surgeons: complications of NT and NT in previously malnourished patients (p = 0.044); and methods for assessing preoperative nutritional status in the group that referred to interact with the NTMT (p =0.01). CONCLUSION: there are gaps in medical education. Only 13.3% were confident about NT, and their knowledge did not justify such confidence. There were no differences between the successes of confident and non-confident about NT in most subjects. The best results came from the group that claimed to be assisted by any NTMT. Better medical educational programs should be goal for this university.
