0,86 (±2,89), já o componente cilíndrico médio foi de -1,53 (±1,09), com predomínio do eixo contra a regra (51,6%). A acuidade visual logarítmica (logMAR) pré-operatória média foi de 0,32 (±0,25). O componente esférico pós-operatório médio foi de -0,02 (±0,53). O sucesso cirúrgico foi obtido em 71 olhos (74,7%), havendo uma diminuição significativa (p<0,001) do componente cilín-drico médio e da acuidade visual logarítmica pós-operatórios, com valores respectivos de -0,61 (±0,55) e 0,08 (±0,14), permanecendo o eixo contra a regra (33,7%). Conclusão: As lentes tóricas mostraram-se seguras e reprodutíveis quanto aos resultados pós-operatórios, tornando-se uma opção importante para obtenção de excelência nos resultados refratométricos finais.

Data de entrada do artigo: 26/05/2013 Data de aceite do artigo: 08/05/2014 resumo O estudo de corte transversal objetivou investigar o comportamento impulsivo de estudantes universitários de uma universidade do sul do Brasil. A amostra foi constituída por 129 estudantes dos cursos de Direito e Engenharia Civil, sendo 49,6% do sexo masculino e 50,4% do sexo feminino. Optou-se por um questionário autoaplicável composto por três partes: a) identificação pessoal; b) situação socioeconômica; e c) escala de impulsividade de Barratt 11. A análise dos dados foi feita por meio da estatística descritiva (frequência simples, percentual, média e desvio padrão) e inferencial pelo teste do qui-quadrado para comparação entre os resultados. A maioria dos estudantes está nas fases iniciais dos cursos (69,8%), sendo que 57,4% cursam Engenharia Civil enquanto 42,6% Direito, e pertencem aos estratos econômicos A e B (88,3%). Quanto ao índice de impulsividade, verificou-se que a maior parte dos participantes está dentro dos limites normais (69%). Na comparação entre o comportamento impulsivo e as variáveis sociodemográficas não houve diferença estatística significativa.

Chlorpromazine is a medication widely used in psychiatry for the treatment of psychoses, especially schizophrenia. Since 1964, published articles have been correlating this medication with the appearance of ocular alterations. In this paper, we report the case of a 65-year-old patient with ocular effects due to long-term therapy with chlorpromazine. Biomicroscopy of both eyes presented diffuse granular brown deposits, most prominent at the deep stroma and corneal endothelium level. Also showed anterior subcapsular brown deposits with a stellate pattern in the lens. The total amount exceeds 2.000g (significant for the ocular alterations described) considering the patient's daily dosage of chlorpromazine of 300mg for ten years. After performing complete ophthalmic evaluation and discarding other causes for the ocular deposits, we diagnosed a secondary corneal deposit and cataract due to the use of chlorpromazine. This case reinforces the importance of periodic follow-up with an ophthalmologist for chlorpromazine users to trace ocular changes, heeding the exposure time and its dosage.

Introduction: Deaths caused by work accidents are a serious public health problem. It is known that statistics referring to general and specific indicators related to work allow raising causal hypotheses of association with existing risk conditions and their occurrence serves to evaluate the measures adopted. Objectives: To analyze fatalities due to accidents at work in Curitiba and in the metropolitan region of 2019, in order to correlate demographic and medicolegal aspects. Materials and methods: An observational and cross-sectional study was carried out to analyze the profile of deaths from work accidents (typical or commuting) in Curitiba/PR and Metropolitan Region in 2019. Data were obtained from autopsy reports, in which the characterization of deaths was based on information from medical records of the hospital of origin or records of professionals from the Legal Medical Institute (IML) who were at the scene of the event to collect the body, as well as toxicological tests carried out by the IML of Curitiba/PR. Results and discussion: There were 15 deaths from work accidents. 86.7% were male and 13.3% were female, aged between 13 and 59 years. 73.3% were single, 20% were married and 6.66% were divorced. As for the profession, bricklayers were 26.6%, 13.3% and self-employed, waiter, elderly caregiver and security, 6.66% each. 42% of the sample had no profession data available in the report. All deaths were due to an occupational accident, with 66.6% of the cases through blunt action, 13.3% through blunt action, 13.3% through electrical energy and 6.66% through biochemical means. The most prevalent medical cause of death was traumatic brain injury, accounting for 46.6% of the total, followed by electropletion, with 13.3%, and septicemia, acute myocardial infarction, acute hemorrhage, neck injury, chest injuries and multiple trauma, with

Purpose To determine normal corneal tomographic parameters in children and adolescents without corneal disease or atopy diagnosis. Methods This descriptive cross-sectional study evaluated patients aged 8-16 years who underwent a complete slit-lamp biomicroscopic examination and tomographic corneal evaluation by a dual Scheimpflug analyzer, excluding those with ocular disease (including allergic conjunctivitis) or a positive prick test for systemic atopies. Results A total of 170 patients were evaluated, and 34 patients (68 eyes) were analyzed once the exclusion criteria were applied. The sample’s mean age was 10.76 ± 2.31 years; with 19 (55.9%) men and 15 (44.1%) women. The mean keratometry in the flat meridian (K flat ), steep meridian (K steep ), and maximum (K max ) were 42.37 ± 1.63D, 43.53 ± 1.65D, and 43.90 ± 1.73D, respectively. The mean values for corneal asphericity (ε 2 ) and thinnest point were 0.28 ± 0.11 and 550.20 ± 37.90 µm, respectively. The inferior-superior asymmetry ratio (I-S) and coma were 0.74 ±0.59D and 0.28 ± 0.12D, respectively. Conclusion The knowledge of normal corneal tomographic parameters and their variation in children and adolescents without corneal disease or atopy may be useful for diagnosing keratoconus and initiating early disease treatment.
