- ItemAcesso aberto (Open Access)Amaurose bilateral por menigoencefalite criptocócica: relato de caso(Conselho Brasileiro de Oftalmologia, 2008-02-01) Aragão, Ricardo Evangelista Marrocos De; Muccioli, Cristina [UNIFESP]; Barrreira, Ieda Maria Alexandre [UNIFESP]; Ribeiro, Daniel Canamary Silveira; Timóteo, Cristiane Nobrega Gularte; Universidade de Regensburg; Universidade Federal do Ceará Hospital Universitário Walter Cantídio; Universidade Federal de São Paulo (UNIFESP); UFC Hospital Universitário Walter CantídioCryptococcal meningitis is caused by the yeast Cryptococcus neoformans. Two varieties are recognized: var. gattii and var. neoformans. It is usually associated with immunosuppressive states, particularly HIV infection. Cryptococcal infection of the central nervous system is uncommon in immunocompetent children and difficult to diagnose. Ocular complications are common. Optic disc swelling was found in 33%. The following report describes a case of meningitis caused by C. neoformans var. gattii in an 8 year-old immunocompetent child who developed optic atrophy. The patient was treated with amphotericin B associated with corticosteroids. Possible therapeutic strategies aimed at reducing visual loss in cryptococcal meningitis have great importance to avoid this important morbidity.
- ItemAcesso aberto (Open Access)Hipertensão intracraniana com manifestações oculares associada ao uso de tetraciclina: relato de caso(Conselho Brasileiro de Oftalmologia, 2005-10-01) Santos, Frederico Xavier Dos; Parolin, André [UNIFESP]; Lindoso, Elissandro Márcio Silva; Santos, Fernando Henrique Xavier; Sousa, Luciene Barbosa De [UNIFESP]; Hospital oftalmológico de Sorocaba; Universidade Federal de São Paulo (UNIFESP); Pontifícia Universidade Católica de SorocabaThe authors describe a young female patient with intracranial hypertension associated with ocular manifestations, during treatment with tetracycline. This is a rare adverse effect described in the medication warnings, and in a few reported cases in the scientific literature.
- ItemAcesso aberto (Open Access)Importância do exame oftalmológico na doença de von Hippel-Lindau(Sociedade Brasileira de Oftalmologia, 2009-08-01) Aragão, Ricardo Evangelista Marrocos de; Barreira, Iêda Maria Alexandre [UNIFESP]; Bezerra, Andreya Ferreira Rodrigues; Ramos, Régia Maria Gondim; Pereira, Felipe Bezerra Alves; Universidade de Regensburg; Universidade Federal do Ceará Hospital Universitário Walter Cantídio Departamento de Oftalmologia; Universidade Federal de São Paulo (UNIFESP); Universidade Federal do Ceará Hospital Universitário Walter Cantídio Serviço de OftalmologiaVon Hippel-Lindau (VHL) disease is an autossomical, dominant inherited tumour syndrom. These tumours may include haemangioblastoma in the retina and central nervous system (CNS), renal cell carcinoma, phaeochromocytoma, islet cell tumours of the pancreas, cystadenoma in the kidney, pancreas, and epididymis. The most common symptoms include: loss of vision, raised intracranial pressure, neurological deficits, paroxysmal raised blood pressure and local pain. We report herein a 29-year-old man with visual loss and cerebellar haemangioblastoma that despite neurological manifestations the diagnosis of VHL was established after the ophthalmological examanination.
- ItemAcesso aberto (Open Access)Novo índice para avaliação da estenose dos seios transversos para diagnóstico de hipertensão intracraniana idiopática(Universidade Federal de São Paulo (UNIFESP), 2017-03-30) Carvalho, Gustavo Balthazar Da Silveira [UNIFESP]; Abdala, Nitamar [UNIFESP]; Matas, Sandro Luiz de Andrade [UNIFESP]; http://lattes.cnpq.br/7071172242012497; http://lattes.cnpq.br/8132921767941082; http://lattes.cnpq.br/1113728462867152; Universidade Federal de São Paulo (UNIFESP)Objective: To assess the role of venous magnetic resonance imaging (MRI) in the detection of transverse sinus stenosis and the importance of this finding in idiopathic intracranial hypertension (HII), and to propose an index that contributes to this diagnosis. METHODS: We retrospectively assessed the exams of patients over the age of 18 who were followed at our institution's pseudotumor ambulatory, who underwent intracranial venous ARM exams from January 2010 to July 2012. The exams were randomly analyzed by 3 radiologists. The evaluators classified the stenosis in the right and left transverse sinuses separately, according to the graduation: 0-normal; 1- Stenosis up to 1/3 (<33%); 2- Stenosis between 1/3 and 2/3 (33-66%); 3 - Stenosis above 2/3 (> 66%) and 4 - Hypoplasia or agenesis. We established an index based on the multiplication of the numbers of this degree of stenosis of each transverse sinus. Point and interval estimation of the sensitivity, specificity and area under the ROC curve were obtained to obtain cutoff points for the index in order to distinguish patient controls. Results: The sample selected in this study consisted of 63 individuals, 32 (50.8%) of the group with diagnosis of HII [31 (96.9%) women and only 1 (3.1%) men] and 31 ( 49.2%) of the control group. The HII group had a higher degree of stenosis when compared to the control group, for all examiners. Values greater than or equal to 4 for diagnosis of HII indicated a sensitivity of 94.7% and specificity of 93.5% Conclusion: We believe that MRA should be included in the evaluation of patients with suspected IBD and bilateral stenosis of the transverse sinus should be valued for diagnosis. The index proposed in this study to classify this stenosis proved to be a fast and accessible method for the diagnosis of IBD.
- ItemSomente MetadadadosA survey of routine treatment of patients with intracranial hypertension (ICH) in specialized trauma centers in São Paulo, Brazil: A 11 million metropole!(Elsevier B.V., 2014-01-01) Alith, Marcela Batan [UNIFESP]; Vidotto, Milena Carlos [UNIFESP]; Jardim, José Roberto [UNIFESP]; Gazzotti, Mariana Rodrigues [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Objective: A survey of intensive care units (ICU) in São Paulo that care for patients with TBI and ICH using the hyperventilation technique.Methods: A questionnaire was given to the physiotherapist coordinator at 57 hospitals in São Paulo, where 24-h neurosurgery service is provided.Results: Fifty-one (89.5%) hospitals replied. From this total, thirty-four (66.7% perform the hyperventilation technique, 30 (85%) had the objective to reach values below 35 mmHg, four (11%) levels between 35 mmHg and 40 mmHg and one (3%) values over 40 mmHg.Conclusions: We concluded that most hospitals in São Paulo perform hyperventilation in patients with severe brain trauma although there are not any specific Brazilian guidelines on this topic. Widespread controversy on the use of the hyperventilation technique in patients with severe brain trauma highlights the need for a specific Global policy on this topic. (C) 2013 Elsevier B.V.
