Enfermedad de Still del adulto Still's disease of adult
Damián Valladares Reyes,Andrés Fojo Mayo,Yoel Alberto Fleites Alonso,Damaris Zayas Hernández
Revista Cubana de Medicina Militar , 2011,
Abstract: Se presenta un paciente del sexo masculino de 51 a os de edad que fue hospitalizado por odinofagia, fiebre elevada, poliartritis, además de leucocitosis con neutrofilia y eritrosedimentación acelerada. Durante el ingreso se le constata poliserositis, neumonitis y miocarditis con insuficiencia cardiaca izquierda, hipertransaminasemia, hiperferritinemia y factor reumatoideo con anti DNA de doble cadena negativos. Se inició tratamiento con corticoesteroides e inmunosupresores (azatioprina). La respuesta no fue la esperada y hubo que cambiar el inmunosupresor por metotrexate. La poliartritis febril de evolución policíclica es la forma de presentación más frecuente de la enfermedad de Still del adulto. La hiperferritinemia mayor de 1 000 ng/mL es una herramienta útil para el diagnóstico y su normalización es indicador de éxito terapéutico. No existen manifestaciones clínicas, ni pruebas de laboratorio patognomónicas, por lo que el diagnóstico continúa siendo por exclusión. This is the case of man aged 51 admitted due to odynophagia, high fever, polyarthritis, as well as leukocytes with neutrophilia and accelerated erythrosedimentation. During admission it was noted polyserositis, pneumonitis and myocarditis with left cardiac insufficiency, hyper-transaminasemia, hyper-ferritinemia and rheumatoid factor with anti-AND of negative double-chain. Treatment was started with corticosteroids and immunosuppressive agents (azathioprine). Response was not the expected one and it was necessary to change the immunosuppressive agent by methotrexate. Febrile polyarthritis of polycyclic evolution is the more frequent presentation of the Still's disease in adult. Hyper-ferritinemia over 1 000 ng/mL is an useful tool for diagnosis and its normalization is an indicator of therapeutical success. There were neither clinical manifestations nor pathognomonic laboratory tests thus, diagnosis remains by exclusion.

Castillo,Hugo; Hernández,Adriana; Dominguez,David; Ojeda,Damaris;
Chilean journal of agricultural research , 2010, DOI: 10.4067/S0718-58392010000300014
Abstract: the efficiency of composting processes with and without the addition of californian red worms (eisenia foetida) was evaluated, using manure of dairy cows to generate organic fertilizer. several parameters were assessed as physio-chemical indicators of maturity, such as temperature, ph, c/n ratio, phytotoxicity and macro and micronutrients at 25 and 54 ws (mature and stored products, respectively). a linear model was used in the statistical analysis, with four replicates that included as fixed effects, the composting systems and time. at 25 wk, both systems reduced the c/n ratio to values of 15.5 in vermicompost and 17.1 in semi-compost. the content of total n, n-no3, ca and some micronutrients also increased. k and na concentrations were higher in the compost than in the vermicompost. the mean of ph presented differences in the two systems of decomposition. the germination index, using lettuce seeds (lactuca sativa l.) var. grandes lagos in vitro, of the decomposition products increased in week 25, indicating the degree of maturity reached. the effect of storage was greater stability of the products by reducing the c/n ratio to 8.13 for vermicompost and 7.05 for compost, as well as an increase in available n content in the form of n-no3 in the case of compost and in the content of ca, mg, na, zn, mn and cu in both systems.

A linear model was used in the statistical analysis, with four replicates that included as fixed effects, the composting systems and time. At 25 wk, both systems reduced the C/N ratio to values of 15.5 in vermicompost and 17.1 in semi-compost. The content of total N, N-NO3, Ca and some micronutrients also increased. K and Na concentrations were higher in the compost than in the vermicompost. The mean of pH presented differences in the two systems of decomposition. The germination index, using lettuce seeds (Lactuca sativa L.) var. Grandes Lagos in vitro, of the decomposition products increased in week 25, indicating the degree of maturity reached. The effect of storage was greater stability of the products by reducing the C/N ratio to 8.13 for vermicompost and 7.05 for compost, as well as an increase in available N content in the form of N-NO3 in the case of compost and in the content of Ca, Mg, Na, Zn, Mn and Cu in both systems. Se evaluó la eficiencia de los procesos de compostaje con y sin la adición de lombriz roja californiana (Eisenia foetida) usando estiércol de vacas lecheras para la generación de abonos orgánicos. Como indicadores de madurez se evaluaron varios parámetros fisicoquímicos tales como temperatura, pH, relación C/N, fitotoxicidad y macro y micronutrientes durante 25 y 54 semanas (productos maduros y almacenados, respectivamente). En el análisis estadístico se usó un modelo lineal con cuatro repeticiones que incluyó como efectos fijos los sistemas de compostaje y el tiempo. Se realizó análisis de varianza y comparación de medias mediante contrastes ortogonales. A las 25 semanas ambos sistemas redujeron la relación C/N a valores de 15,5 en vermicompost y de 17,1 en semi-compost, además se incrementó el contenido de N-total, N-NO3, Ca y de algunos micronutrimentos. La concentración de K, y Na fueron más altos en compost que en vermicompost. La media de pH presentó diferencia para los sistemas de descomposición. El índice de germinación usando semillas de lechuga (Lactuca sativa L.) var. Grandes Lagos in vitro de los productos de descomposición se incrementó en la semana 25 indicando el grado de madurez alcanzado. El efecto del almacenamiento

Agentes físicos en el tratamiento de la enfermedad pulmonar obstructiva crónica
Humberto Cívico Quintero,Damaris Reyes Hernández,Gloria Hernández Madan,Luis Ng Lio
Revista Cubana de Medicina Militar , 2002,
Abstract: Se hizo una revisión bibliográfica relacionada con el efecto de los agentes físicos sobre la enfermedad pulmonar obstructiva crónica. Se observó que los agentes de mayor influencia positiva sobre esta afección fueron: el calor infrarrojo, el ultrasonido, la diatermia, la ultra alta frecuencia, la magnetoterapia, el láser y el masaje vibratorio. En experiencias obtenidas en la aplicación fisioterapéutica de estos agentes, se ha comprobado beneficios en la conductancia aérea intrapulmonar. A literature review about the effect of physical agents on chronic obstructive pulmonary disease was made. It was observed that the most positive influential factors on the affection were: infrared heat, ultrasound, diathermia, ultrahigh frequency, magnetotherapy, laser and vibration massage. Experience in the application of these agents has shown benefits for intrapulmonary air conduction.
Nitratos orgánicos en su segundo siglo. Organic nitrates in their second century.
Raymid García Fernández,Damaris Hernández Véliz,David garcía Barreto
Revista Cubana de Cardiología y Cirugía Cardiovascular , 2000,
Abstract: Se hizo una revisión actualizada de los nitratos orgánicos que tienen casi un siglo y medio de introducidos en la terapéutica de la cardiopatía isquémica. Este grupo de drogas induce la formación de óxido nítrico en la célula del músculo liso arterial y así provoca un aumento en los niveles de guanosín monofosfato cíclico, que a su vez, reduce las concentraciones citosólicas de ión calcio lo que causa vasodilatación principalmente venosa. La reducción del retorno venoso al corazón disminuye el trabajo cardiaco y el consumo de oxígeno miocárdico. Su eficacia clínica está ampliamente demostrada, por lo que continúan siendo medicamentos de primera línea en el tratamiento de diversas afecciones cardiacas. Un efecto adverso muy importante es la tolerancia, la cual ha llevado a la búsqueda de combinaciones terapéuticas de nitratos para lograr su reducción. No obstante, parece ser que lo fundamental es lograr un período libre de nitratos, reducir la dosis a la mínima y evitar algunas formas farmacéuticas de larga duración que provocan la aparición de este evento. Parece razonable asumir que ocurra tolerancia cruzada entre nitratos, lo que restaría eficacia al tratamiento de las crisis anginosas. Otro efecto adverso es el síndrome de supresión que puede ser causa de un aumento de la frecuencia y gravedad de las crisis isquémicas. An updated review of the organic nitrates that were introduced in the therapeutics of ischemic heart disease almost a century and a half ago was made. This group of drugs induce the formation of nitric oxide in the cell of the arterial smooth muscle, provoking this way an increase of the levels of cyclic guanosine monophosphate that, at the same time, reduces the cytosolic concentration of calcium ion, causing mainly venous vasodilation. The reduction of the venous return to the heart reduces heart work and the consumption of myocardial oxygen. As their clinical efficiency has been largely demonstrated, these drugs are still first-line drugs in the treatment of various cardiac affections. A very important adverse effect is tolerance, which has led to the search of therapeutic combinations of nitrates to achieve its reduction. However, it seems that the fundamental thing is to attain a nitrate-free period, to reduce the dose to the minimum and to avoid the administration of some sustained-release drugs that give rise to this event. It seems reasonable to assume that cross tolerance may occur among nitrates, which would reduce the efficiency of the treatment of anginal crises. Another adverse effect is the syndrome of suppression that ma
