En busca de las sociólogas fundadoras: Marianne Weber
Arango Gaviria Luz Gabriela,Arias Pinilla Giovanna
Revista Colombiana de Sociología , 2006,
Abstract: Con miras a difundir el trabajo de las académicas norteamericanas por rescatar la obra de Mlarianne Weber, entre otras sociólogas fundadoras, hemos traducido un fragmento de su ensayo: "Autoridad y autonomía en el matrimonio". En éste, la autora analiza las distintas configuraciones culturales del matrimonio en la historia occidental, desde el "patriarcado primitivo" hasta las formas modernas de matrimonio civil y religioso. La autora destaca la influencia de las doctrinas católicas y protestantes en la transformación de esta institución hacia una mayor equidad entre los sexos y se ala críticamente las con tradicciones de las formas modernas de contra to matrimonial que preservan la primacía masculina y contradicen las ense anzas éticas del idealismo alemán en torno a la libertad. Marianne V'cber defiende un ideal matrimonial que respete y reconozca plenamente la individualidad y autonomía de la mujer. Palabras clave: Marianne Weber, matrimonio, mujeres, igualdad.

Abstract: by using the methodology of bry and boschan (1971), this work proposes precise dates for the business cycles occurred in colombia between 1980 and 2007 identifying the phases of boom and slump. during the sample period, five complete cycles were detected, which happened to be asymmetric such as those of the united states. this means that expansions are longer than recessions. on average, the cycles in colombia between 1983 and 2007, according to ipi (industrial production index), were of 45.6 months (3.8 years) approximately. the longer cycles occurred at the end of eighties and mid nineties with average durations of 68 months.

Abstract: the superoxide anion produced by the nadph oxidase system of the phagocytic cells is part of the reactive oxygen species involved in the defense against pathogenic microorganisms. its importance is evidenced in the chronic granulomatous disease (cgd), a primary immunodeficiency caused by mutations in the genes that code the proteins of the nadph oxidase system. the knock-out mice for some of the proteins of the nadph oxidase system have allowed to understand the function of the ros in the destruction of pathogenic microorganisms, the regulation of the inflammatory process, and the physiology of the nadph oxidase system, it is expected that this class of animal models makes possible to attain advances in the understanding of the events included in the genic therapy for the cgd, of the paradigms about the role of the ros in the defense of the host, and in the description of the signaling pathways involved in the activation of this system

Revista Cubana de Pediatr?-a , 2008,
Abstract: introduction. the lumbar puncture is indicated in the initial evaluation of the febrile newborn without signs of focalization. however, it may fail and create uncertainty in the management of the antibiotic treatment. the objective of this paper was to verify the treatment and evolution of the febrile newborn infants without signs of focalization, when the lumbar puncture failed in the initial evaluation. methods. 150 febrile newborn infants without signs of focalization and with failed lumbar puncture in the initial evaluation that were admitted in the neonatology service of our hospital between 1992 and 2000 were studied. all the patients were classified according to the criterion of low risk of severe bacterial infection. the use of antibiotic treatment was subjected to the consideration of the physician that made the initial evaluation. the index and rate of failed lumbar puncture were calculated and the relation between the indication of the antibiotic treatment at the beginning and the classification of severe bacterial infection risk was measured. the evolution of the patients was checked. results. 150 of the 1174 lumbar punctures failed (8.5 %) for an index of 9.2. the newborn infants considered as high risk received antibiotic treatment more frequently (23.3 %) compared with those classified as low risk, who were predominantly treated without antibiotics (36.0 %) (p = 0.03). 149 neonates were discharged alive (99.3 %), with or without use of antibiotics. however, there was a dead child classified as high risk for severe bacterial infection that received antibiotic treatment from the beginning. conclusions. the lumbar puncture may fail on evaluating the febrile newborn infants without signs of focalization. the indication of antimicrobial treatment in these patients was significantly connected with the classification of risk for severe bacterial infection, and the management of the antibiotic treatment before a failed lumbar puncture did not determine an adv

Abstract: introduction. the aim of present research was to set which clinical or laboratory criteria of the method to assess the severe bacterial infection (sbi) risk allow to discriminate more likely those febrile newborns (nb) without focalizations signs (wfs) presenting with meningitis. methods. a retrospective study was conducted in 438 febrile nb admitted during 40 months. study variables included the assessment criteria of sbi risk and the association of these variables for the nb group without neither type of sbi nor aseptic meningitis (am) compared with those presenting with bacterial meningitis and with am separately. results. frequency of bm and of am was of 2,5 and 9,3%, respectively. except for the positive cyturia and the perinatal positive backgrounds of sepsis, remainder clinical and laboratory variables used to assess the risk of sbi of febrile nb wfs were associated to presence of bm. fever ≥ 39oc or persistent fever or recurrent was associated significantly with a am. conclusions. diagnosis of meningitis (aseptic or bacterial) is common in febrile nb-ssf verifying that fever ≥39oc and the persistent or recurrent fever are elements associated with presence of meningitis, thus, when they are present must to verify the possibility of some of these infections. because of bm is the infection of worse prognosis also we must to take into account the other criteria related particularly to presence of a infectious toxic state.

Díaz álvarez,Manuel; Arango Arias,María Isabel; Moreno Vázquez,Olimpo;
Revista Cubana de Pediatr?-a , 2006,
Abstract: algunos autores apoyan la realización de una radiografía de tórax en la evaluación inicial del lactante peque?o febril; otros no son partidarios de esta estrategia. con el objetivo de valorar la necesidad de realizar radiografía de tórax en la evaluación inicial de un neonato febril, si no existen signos de focalización, se realizó un estudio observacional, caso-control, que incluyó todos los recién nacidos febriles sin signos de focalización ingresados en el servicio de neonatología, desde febrero de 1992 hasta diciembre de 1998. en el período de 1992 a 1995 no existían políticas uniformes para la atención de estos pacientes. se estudió la indicación de la radiografía de tórax en la evaluación inicial, así como distintas variables asociadas a la indicación de este examen y a la presencia de bronconeumonía. se realizó radiografía de tórax inicialmente a 191 de 1 276 (15 %) neonatos febriles, 7 (3,6 %) de los cuales mostraron tener lesiones inflamatorias. evolutivamente se diagnosticaron 2 pacientes más con bronconeumonía y la tasa de incidencia de bronconeumonía fue 0,7 %. en el período de 1992 a 1995 se realizó radiografía de tórax a 127 de 608 (20,8 %) de los pacientes evaluados inicialmente por fiebre y a 64 de 668 (9,5 %) (p < 0,001). de los evaluados entre 1996 y 1998. las variables asociadas con la indicación del estudio radiográfico fueron: antecedentes de riesgo de sepsis perinatal (odds ratio = 2,73), impresión de ni?o tóxico-infeccioso (odds ratio = 4,05) y conteo global de leucocitos sanguíneos < 5,0 o 20,0 x 109/l (odds ratio = 2,45) (p < 0,05). estas dos últimas fueron las variables asociadas con la presencia de bronconeumonía (p < 0,05). la frecuencia de bronconeumonía en los neonatos febriles sin signos de focalización es baja. el estudio radiográfico de tórax no debe ser un examen de rutina en la evaluación inicial de estos pacientes.
