Xantogranulomatosis orbitaria: Enfermedad de Erdheim-Chester
Rozas Reyes,P; Searis González,A; González Rodríguez,CM;
Archivos de la Sociedad Espa?ola de Oftalmología , 2004, DOI: 10.4321/S0365-66912004001000009
Abstract: case report: a patient was studied because of upper lid bilateral edema and xanthelasmae-like lesions after three years of evolution. during the ophthalmologic examination orange-yellowish lesions and two symmetrical tumours were observed on the temporal part of both upper lids. corticoid-therapy was undertaken which reduced the size of the tumours, however the size increased again after the discontinuation of treatment. a biopsy was performed and lid xanthogranulomatosis was diagnosed. other systemic examinations were normal. discussion: erdheim-chester disease is a xanthogranulomatosis that can affect ocular and periorbital structures. combination of xanthelasmae-like lesions and bilateral orbital masses should make us consider this process and try to locate any associated systemic conditions.

Abstract: Caso clínico: Paciente con edema bilateral de párpados superiores y lesiones similares a xantelasmas de tres a os de evolución. La exploración oftalmológica mostraba dos tumoraciones temporales simétricas en ambos párpados superiores con lesiones naranjo-amarillentas. Se pautaron corticoides que hicieron disminuir el tama o de las tumoraciones, con recidiva de los mismos al suspender dicha medicación. La biopsia reveló una xantogranulomatosis palpebral. El resto de las exploraciones sistémicas fueron normales. Discusión: La enfermedad de Erdheim-Chester es una xantogranulomatosis que puede afectar a las estructuras oculares y periorbitarias. La combinación de lesiones similares a xantelasmas y masas orbitarias bilaterales deben hacernos pensar en este proceso y buscar la posible afectación sistémica.

Archivos de la Sociedad Espa?ola de Oftalmología , 2004,
Abstract: Caso clínico: Hombre de 52 a os que acudió a urgencias por disminución progresiva de su visión en el ojo derecho. Como antecedentes había tenido nefrectomía derecha por carcinoma renal 7 a os antes y neumonectomía derecha por metástasis 3 meses antes. En la funduscopia se observaba una masa coroidea en ojo derecho, compatible con metástasis. Se realizó enucleación. Durante un a o permaneció sin progresión pero en los últimos seis meses ya ha aparecido. Discusión: Las metástasis coroideas de carcinoma renal son infrecuentes y pueden ocurrir varios a os después de la curación del primario. Su sintomatología es variable y su aspecto poco característico por lo que puede dificultar su diagnóstico diferencial. Case report: A fifty-two year-old man who came to our emergency room because of gradual loss of vision in his right eye. He had suffered right nefrectomy for renal cell carcinoma seven years previously and pneumectomy for metastasis in his right lung three months ago. In the fundus examination a choroidal mass was found in his right eye, suggesting metastasis. Treatment was enucleation of the affected eye. During the first year there was no progression, but in the last six months it has re-appeared. Discussion: Choroidal metastasis of renal cell carcinoma is rare and can appear years after treating the primary tumour. Its symptoms are variable, and its shape is not very characteristic so it can be difficult to make a differential diagnosis.

Degradation of chlorophenol mixtures in a fed-batch system by two soil bacteria
I Durruty, E Okada, JF González, SE Murialdo
Water SA , 2011,
Abstract: This work was undertaken to investigate the effect of variations of the feed rate on a fed-batch set-up used to degrade xenobiotics. The mixture of substrates was composed of PCP, 2,4,6 TCP and 2,3,5,6 TeCP (pentachlorophenol, 2,4,6 trichlorophenol and 2,3,5,6 tetrachlorophenol respectively). Two acclimated bacteria isolated from soil were used: Pseudomonas aeruginosa and Achromobacter sp. nov. The different flow rates tested were: I: 0.5 m min-1, II: 1.67 m min-1 and III: 2.00 m min-1. Our results show that during fed-batch operation the 2,4,6 TCP exhibits an earlier degradation than the other compounds, for all of the flow rates tested. This indicates that in this case the degradation of the most recalcitrant compounds (PCP and 2,3,5,6 TeCP) is benefited by the increase in biomass of bacteria, due to the metabolisation of a less recalcitrant compound (2,4,6 TCP). The defined parameter, specific degradation rate (SDR), was demonstrated to be very useful for comparing the degradation abilities at different flow rates of a fed-batch system. The degradation efficiencies were shown to be higher than 90% for all of the cases and to decrease as the feed rate increases. However, the SDR, a parameter that involves the rate of degradation and the biomass, increases as the flow rate increases. At a feed flow rate of 2 m min-1 SDR reaches a maximum of 12.476 x 10-10 mgCP h-1 CFU-1. Finally, among the feed flows tested, taking into account both the degradation efficiency and the SDR, 2 m min-1 is the most convenient flow rate for chlorophenol degradation in fed-batch systems. An even higher degradation efficiency (97%) can be achieved by using the feed rate of 2 m min-1 followed by an additional batch post-treatment of 2 h, with a SDR of 13.136 x 10-10 mg CP h-1 CFU-1.

Revista chilena de obstetricia y ginecología , 2010, DOI: 10.4067/S0717-75262010000600011
Abstract: background: one hundred and thirty six millions of births occurred annually at global level. ten millions of those children will die before their first birthday. approximately five hundred thousand of mothers also will die in the same period, for causes associated to pregnancy, delivery or puerperium. 99 % of all of this global tragedy occurs in the poorest countries of the world. more than 70% of maternal death occurred because five main causes: hemorrhage, infections, abortion, hypertension and obstructed labor. a change in the etiological profile was observed, increasing the proportion of "indirect" (no obstetrics) causes in the countries with indicators more favorable as cuba, costa rica, uruguay and chile. the infant and under five mortality in the region have been decreased in around 50% between 1990 and 2005. conclusion: despite latin america's overall declines in mortality and gains in life expectancy over the past few decades, inequity remains a leading health problem. data from the region on maternal, newborn, infant, and child health show better outcomes among women with higher socioeconomic status in comparison with the poorest people within and also between the countries in the region. in the context of the global effort to attain millennium development goals number 4 (reduce by two-thirds, between 1990 and 2015, the under-five mortality rate) and 5 (reduce by three-quarters, the maternal mortality ratio) and reduce health inequities, it is crucial to disseminate successful experiences in order that its achievements can be replicated elsewhere.

Abstract: Antecedentes: A nivel global, ocurren 136 millones de nacimientos, 10 millones de estos ni os fallecerán antes de su primer a o de vida. De la misma manera aproximadamente 500 mil madres morirán en el mismo período por causas asociadas al embarazo, parto y puerperio. El 99% de esta tragedia mundial ocurre en los países más pobres de la tierra. Más del 70% de las muertes maternas ocurren por cinco causas principales: hemorragias, infecciones, aborto, hipertensión y parto obstruido. Se ha observado un cambio en el perfil etiológico en aquellos países con experiencia mas favorables, como Cuba, Costa Rica, Uruguay y Chile, países en los cuales ha aumentado la proporción de las llamadas causas indirectas (no obstétricas) de mortalidad materna. La mortalidad infantil y la del menor de 5 a os, ha disminuido en alrededor de un 50% en la región. Conclusión: A pesar de las mejorías globales en la salud materno-infantil y aumento de la esperanza de vida en la región de América Latina, la inequidad permanece como problema crucial. Existe información publicada que muestra que los mejores indicadores en salud materna, del recién nacido y del ni o ocurre en mujeres con mejor situación socio-económica, estas diferencias se observan dentro y entre los países de la región. En el contexto del logro de los Objetivos Materno Infantiles del Milenio (ODM 4 y 5), es crucial la diseminación de las experiencias de los países con indicadores más favorables de la región.

Encomiendas, Encomenderos e Indígenas Tributarios del Nuevo Reino de Granada en la primera mitad del Siglo XVII
González P. Alvaro
Anuario Colombiano de Historia Social y de la Cultura , 1964,
Abstract: El documento sobre Encomiendas, Encomenderos e Indios Tributarios de la Audiencia de Nueva Granada, producido en 1653 por Rodrigo Zapata, escribano de visitas, es, de los encontrados y publicados hasta el momento sobre este tema, el único que nos presenta una visión panorámica de las encomiendas en la mayor parte del territorio de la actual Republica de Colombia y parte de Venezuela. En él se resumen los recuentos de indígenas tributarios hechos por visitadores reales desde comienzos del siglo XVII, anotando el lugar de la encomienda, el nombre de los encomenderos y la tasación de los tributos. Por estos datos el documento resulta útil no solo para la historia social, sino también para el estudio de la toponimia indígena de casi todo el territorio colombiano y para la historia económica de la época colonial.
