Diagnostic criteria for blepharospasm: A multicenter international study
Background: There are no widely accepted criteria to aid the physician in diagnosing BSP. Objective: To validate recently proposed diagnostic criteria for blepharospasm in a larger and geographically diverse population and to develop a screening system for blepharospasm. Methods: Video-recordings from 211 blepharospasm patients and 166 healthy/disease controls were examined by 8 raters. Agreement for presence of orbicularis oculi spasms, sensory trick, and increased blinking was measured by k statistics. Inability to voluntarily suppress the spasms was asked by the examiner but not captured in the video. Patients/controls were also requested to fill a self-administered questionnaire addressing relevant blepharospasm clinical aspects. The diagnosis at each site was the gold standard for sensitivity/specificity. Results: All the study items yielded satisfactory inter/intra-observer agreement. Combination of items rather than each item alone reached satisfactory sensitivity/specificity. The combined algorithm started with recognition of spasms followed by sensory trick. In the absence of a sensory trick, including âincreased blinkingâ or âinability to voluntarily suppress the spasmsâ or both items yielded 88â92% sensitivity and 79â83% specificity. No single question of the questionnaire yielded high sensitivity/specificity. Serial application of the questionnaire to our blepharospasm and control subjects and subsequent clinical examination of subjects screening positive by the validated diagnostic algorithms yielded 78â81% sensitivity and 83â91% specificity. Conclusion: These results support the use of proposed diagnostic criteria in multi-ethnic, multi-center cohorts. We also propose a case-finding procedure to screen blepharospasm in a given population with less effort than would be required by examination of all subjects
Consumo de drogas y violencia laboral en mujeres que trabajan, un estudio multicĂ©ntrico: MĂ©xico, PerĂș, Brasil Consumo de drogas e violencia laboral em mulheres que trabalham, um estudo multicĂȘntrico: MĂ©xico, Peru, Brasil Drug consumption and occupational violence in working women, a multicenter study: Mexico, Peru, Brazil
Los propĂłsitos del estudio fueron: 1) Determinar la proporciĂłn de consumo de drogas de las mujeres que trabajan; 2) Identificar algunos factores de riesgo personales y laborales que puedan predecir el consumo de drogas; 3) Identificar la presencia de violencia laboral y su relaciĂłn con el consumo de drogas; 4) Identificar diferencias y similitudes de consumo de drogas y violencia laboral en las mujeres de las tres comunidades de MĂ©xico (Monterrey), PerĂș (Lima) y Brasil (Rio de Janeiro). El estudio fue multicĂ©ntrico, descriptivo, correlacional y comparativo, con una muestra de 903 mujeres. En los resultados se observa que la proporciĂłn de consumo de alcohol en MĂ©xico fue del 11%, en PerĂș del 53% y en Brasil del 45%. El consumo de drogas ilĂcitas en MĂ©xico fue del 5% y en PerĂș del 6%. La presencia de violencia laboral fue del 16% en las mexicanas, 24% en las peruanas y 39% en las brasileñas.<br>Os propĂłsitos do estudo foram: 1) Determinar a proporção de consumo de drogas entre mulheres que trabalham; 2) Identificar alguns fatores de risco pessoais e laborais que possam predizer o consumo de drogas; 3) Identificar a presença de violĂȘncia laboral e sua relação com o consumo de drogas; 4) Identificar diferenças e semelhanças no consumo de drogas e violĂȘncia laboral nas mulheres das trĂȘs comunidades de MĂ©xico (Monterrey), PerĂș (Lima) e Brasil (Rio de Janeiro).

A multicenter, descriptive, correlational and comparative study was carried out, with a sample of 903 women. The results show that 11% of the participants in Mexico consume alcohol, 53% in Peru and 45% in Brazil. The consumption of illicit drugs corresponded to 5% in Mexico and 6% in Peru. The presence of occupational violence was found in 16% of the Mexican participants, 24% of the Peruvians and 39% of the Brazilians
