Conmoci\uf3n cardiaca
La conmoci\uf3n cardiaca es fibrilaci\uf3n ventricular resultado de traumatismo contuso en el pecho y es un trarstorno que pone en peligro la vida; son indispensables las maniobras de reanimaci\uf3n temprana y la desfibrilaci\uf3n. Puede suceder durante encuentros deportivos o por abuso de ni\uf1o, y la mayor\ueda de los enfermos son varones menores de 16 a\uf1os de edad. El pron\uf3stico de la conmoci\uf3n cardiaca depende de la disponibilidad de la desfibrilaci\uf3n cardiaca. Los desfibriladores autom\ue1ticos en sitios convenientes cerca de encuentros deportivos, combinados con mejor\ueda en la educaci\uf3n de la reanimaci\uf3n cardiopulmonar. mejoran las probabilidades de.supervivencia despu\ue9s de este fen\uf3meno que no es frecuente. En los sobrevivientes se han observado anormalidades transitorias de la conducci\uf3n cardiaca y arritmias: por ello. se indica verificar la situaci\uf3n cardiaca saludable antes de reanudar las actividades deportivas

Asymmetries and visual field summaries as predictors of glaucoma in the ocular hypertension treatment study
PURPOSE. To evaluate whether baseline visual field data and asymmetries between eyes predict the onset of primary open-angle glaucoma (POAG) in Ocular Hypertension Treatment Study (OHTS) participants. METHODS. A new index, mean prognosis (MP), was designed for optimal combination of visual field thresholds, to discriminate between eyes that developed POAG from eyes that did not. Baseline intraocular pressure (IOP) in fellow eyes was used to construct measures of IOP asymmetry. Age-adjusted baseline thresholds were used to develop indicators of visual field asymmetry and summary measures of visual field defects. Marginal multivariate failure time models were constructed that relate the new index MP, IOP asymmetry, and visual field asymmetry to POAG onset for OHTS participants. RESULTS. The marginal multivariate failure time analysis showed that the MP index is significantly related to POAG onset (P < 0.0001) and appears to be a more highly significant predictor of POAG onset than either mean deviation (MD; P = 0.17) or pattern standard deviation (PSD; P = 0.046). A 1-mm Hg increase in IOP asymmetry between fellow eyes is associated with a 17% increase in risk for development of POAG. When threshold asymmetry between eyes existed, the eye with lower thresholds was at a 37% greater risk of development of POAG, and this feature was more predictive of POAG onset than the visual field index MD, though not as strong a predictor as PSD. CONCLUSIONS. The MP index, IOP asymmetry, and binocular test point asymmetry can assist in clinical evaluation of eyes at risk of development of POAG.</p
