Feocromocitoma asociado con embarazo
Bufalino,Gesualdo; Cortés Charry,Rafael; Sosa,Héctor; Yaremenco,Francisco;
Revista de Obstetricia y Ginecología de Venezuela , 2007,
Abstract: the case of a 22 year old patient followed in the high risk pregnancy clinic due to diagnosis of pheocromocytoma, with adecuate control of blood pressure, was reported. at 35 weeks of gestation, a cesarean section with adrenalectomy was indicated; however, during surgery she presented high blood pressure which did not respond to the pharmacological therapy, so adrenalectomy was postponed. after surgery, she presented uterine atony, hence subtotal hysterectomy and right adrenalectomy was performed. the histology confirmed the diagnostic of pheocromocytoma. the multidisciplinary management allowed in this case a satisfactory maternal-fetal outcome

Abstract: The aims of this work were to evaluate the correlation, to adjust and select simple and multiple linear statistical models between elemental components (carbon, hydrogen and oxygen) and ash content with higher heating value for plant biomass; to use the principle components analysis for the creation of an energetic development index and to adjust a linear model between energetic development index and higher heating value. Eight types of biomass were used. Three linear and nine multiple statistical models were adjusted. The best models were selected based on the significance of coefficients, adjusted determination coefficient, estimative standard error, coefficient of variation, linearity of parameters, normality, presence of heterocedasticity and lack of error correlation. The variance inflation factor was determined for linear multiple models. High correlation between the variables studied was found. Models 1, 3 and 11 were considered most adequate. Practical use of model 2 is not possible. Principle components analysis was efficient in obtaining an energetic development index of lignocellulosic residues and it may be used for solving multicollinearity found between variables considered. doi: 10.4336/2011.pfb.31.66.113 Os objetivos do trabalho foram avaliar a correla o, ajustar e selecionar modelos estatísticos lineares simples e múltiplos entre os componentes elementares (carbono, hidrogênio e oxigênio) e o teor de cinzas com o poder calorífico superior da biomassa vegetal; utilizar a análise de componentes principais para a cria o de um índice de desempenho energético e ajustar um modelo linear entre o índice de desempenho energético e o poder calorífico superior. Utilizaram-se oito tipos de biomassa. Foram ajustadas equa es referentes a três modelos estatísticos lineares simples e nove múltiplos. Os melhores modelos foram selecionados com base na significancia dos seus coeficientes, no coeficiente de determina o ajustado, no erro padr o da estimativa, no coeficiente de varia o, na linearidade dos parametros, na normalidade, na presen a de heterocedasticidade e ausência de autocorrela o dos erros. Para os modelos lineares múltiplos, determinou-se o fator de infla o de variancia. Encontrou-se alta correla o entre as variáveis. Os modelos 1, 3 e 11 foram considerados os mais adequados. A utiliza o prática do modelo 2 foi impossibilitada. A análise de componentes principais foi eficiente na obten o de um índice de desempenho energético dos resíduos lignocelulósicos e pode ser utilizada para contornar a multicolinearidade encontrada entre as var

Abstract: This work aimed to quantify and compare chemical and energetic properties of Australian red cedar Toona ciliata MJ Roem var. australis (FV Muell.) C. DC wood from thinning and primary sawing for reconstituted panel and energy production; and also to verify the efficiency of extractive removal by water treatments, in order to improve wood quality for particleboard production. Lignin, holocellulose, extractives, ash, carbon, hydrogen, oxygen, nitrogen and sulfur contents and higher heating value were determined. Two water treatments for extractive removal were performed: immersion in cold water for 24 hours and immersion in boiling water for 2 hours. Lower values of ash, holocellulose, hydrogen and nitrogen contents and higher contents of lignin, total extractives, hydrogen and nitrogen contents were found for wood from primary sawing residues. For other properties, the values were significantly equal. Australian red cedar wood presents high extractive content, being water pre-treatment necessary for the production of some particleboards. Higher heating values of materials indicate potential for energy production. doi: 10.4336/2012.pfb.32.70.13 O objetivo desse trabalho foi quantificar e comparar as propriedades químicas e energéticas da madeira de cedro australiano Toona ciliata MJ Roem var. australis (FV Muell.) C. DC proveniente de desbaste e desdobro para produ o de painéis reconstituídos e energia, além de verificar a eficiência da remo o de extrativos por tratamentos em água para viabilizar a produ o de painéis de partículas. Os teores de lignina, holocelulose, extrativos totais, cinzas, carbono, hidrogênio, oxigênio, nitrogênio, enxofre e poder calorífico superior foram determinados. Dois tratamentos em água para remo o de extrativos foram realizados nos materiais: imers o em água fria durante 24 horas e em água fervente durante 2 horas. Foram encontrados menores teores de cinzas, holocelulose, hidrogênio e nitrogênio e maiores teores de lignina e extrativos totais nos resíduos de madeira proveniente de costaneiras de desdobro primário. Para as outras propriedades, os valores foram estatisticamente iguais. A madeira de cedro australiano apresenta elevado teor de extrativos, sendo o pré-tratamento em água necessário para a produ o de determinados painéis de partículas. Os valores de poder calorífico dos materiais indicam potencial para a produ o de energia. doi: 10.4336/2012.pfb.32.70.13

Abstract: Se comunica el caso de gestante de 22 a os, controlada en la consulta de alto riesgo por diagnóstico de feocromocitoma, con control adecuado de las cifras de tensión arterial. Se realizó cesárea segmentaria más adrenalectomía a las 35 semanas; durante el acto operatorio presentó crisis hipertensiva de difícil manejo, por lo cual, se difirió la adrenalectomía. En el posoperatorio inmediato presentó atonía uterina que ameritó realizar histerectomía subtotal e inmediatamente adrenalectomía derecha. El estudio histopatológico confirmó el diagnóstico de feocromocitoma. El manejo multidisciplinario permitió una evolución favorable materno-fetal The case of a 22 year old patient followed in the high risk pregnancy clinic due to diagnosis of pheocromocytoma, with adecuate control of blood pressure, was reported.
