Abstract: La figura del Seguro se hace peculiar, atendiendo a la perspectiva que asume la relación contractual en cuanto a sus particularidades: negocio consensual, adhesivo, aleatorio; características que, sin duda lo convierten en una de las figuras más controversiales del mundo contractual.
Espesor corneal central en el glaucoma crónico simple Central corneal thickness in chronic simple glaucoma
Elizabet Lorenzo Ojeda,Juana Caridad Suárez Pérez
Revista Cubana de Medicina Militar , 2012,
Abstract: Objetivo: determinar si el espesor corneal central es un factor a considerar en el manejo de los pacientes con glaucoma crónico simple. Métodos: se realizó un estudio de casos y controles: un grupo con 100 pacientes con glaucoma crónico simple y otro con igual número de pacientes (personas sanas que acudieron a consulta por síntomas de astenopía ocular). Resultados: la presión intraocular aumentó de manera proporcional con el espesor corneal central con diferencias significativas (p= 0,000) entre ambos grupos. Con el aumento de la relación copa-disco, disminuye el espesor corneal central (p= 0,04 y 0,008). Se encontraron cifras más bajas de espesor corneal central en el grupo de casos. Conclusiones: el espesor corneal central fue directamente proporcional a los niveles de presión intraocular e inversamente proporcional a la relación copa-disco, por lo que es un factor a considerar en el manejo del glaucoma crónico simple. Objective: determine whether central corneal thickness is a factor to be considered in the management of patients with chronic simple glaucoma. Methods: a case-control study was conducted with a group of 100 patients with chronic simple glaucoma and a group of 100 healthy persons who presented with symptoms of visual asthenopathy. Results: increase in intraocular pressure was proportional to central corneal thickness, with significant differences (p= 0.000) between the two groups. As the cup-disc ratio increases, central corneal thickness decreases (p= 0.04 and 0.008). Lower central corneal thickness values were found in the case group. Conclusions: central corneal thickness was directly proportional to intraocular pressure levels, and inversely proportional to cup-disc ratio. It is therefore a factor to be considered in the management of chronic simple glaucoma.
Fixed-point theorems for multivalued non-expansive mappings without uniform convexity
T. Domínguez Benavides,P. Lorenzo Ramírez
Abstract and Applied Analysis , 2003, DOI: 10.1155/s1085337503203080
Abstract: Let X be a Banach space whose characteristic of noncompact convexityis less than 1 and satisfies the nonstrict Opial condition. Let C be a bounded closed convex subset of X, KC(C) the family of allcompact convex subsets of C, and T a nonexpansive mapping from C into KC(C). We prove that T has a fixed point. The nonstrict Opial condition can be removed if, in addition, T is a 1-χ-contractive mapping.
Repercusión familiar del comportamiento suicida
Pérez Martínez,Víctor T.; Lorenzo Parra,Zurama;
Revista Cubana de Medicina General Integral , 2004,
Abstract: a descriptive cross-sectional study was carried out in 34 families in which a suicidal behavior was observed from 2001 to 2003. the sense of repercussion of the suicidal behavior was mostly unfavorable for health in 82.4 % of the family groups, with a negative predominance in all its areas. in the two families where suicide was committed, the global family repercussion was considered as severe. it was determined that excepting the socioeconomic area that showed a moderate affectation, the other 3 areas had a severe affectation. in the 32 families where a suicide attempt ocurred, it was confirmed a clear prevalence of the elevated global family repercussion in this event. the areas with the highest affectation were the sociopsychological, in 62.5 %, followed by family functioning, in 53.1 %. in general, the sense of the repercussion of the suicidal behavior was mostly unfavorable for the health of the family groups with negative predominance of all its areas.
Comportamiento del sistema de redes de apoyo social en familias que sufren la conducta suicida
Pérez Martínez,Víctor T.; Lorenzo Parra,Zurama;
Revista Cubana de Medicina General Integral , 2004,
Abstract: in 2 families, where suicide was committed, the global family repercussion was classified as severe,whereas in the other 32 family groups in which a suicide attempt took place, a predominance of elevated family repercussion was found in 56.2 %. in both psychotraumatizing events, the most used support networks were those from the health institutions and from the own family. the most frequent social support was the informative, followed by the emotional. the adaptative capacity of the family groups that suffered from the suicide attempt fluctuated from fair to good. all the groups with a suicide committed showed a poor adaptative capacity. a marked increase of the adaptative resources of the family was observed as the social support received was greater.
El impacto del déficit mental en el ámbito familiar
Pérez Martínez,Víctor T.; Lorenzo Parra,Zurama;
Revista Cubana de Medicina General Integral , 2007,
Abstract: a descriptive and transversal study was made to determine the degree of family repercussion of mental deficit on a total of 106 families, which had members presenting some degree of mental retardation. in all study families it was obvious a determined degree of family repercussion, affecting in high and moderate level all areas included in this situation. repercussion sense of mental deficit was especially unfavourable for health of 84 % of family nuclei. it was confirmed that depending on increment of mental deficit, repercussion of this event in family environment increase significantly.
