A relationship between disaccharidase and diamine oxidase (DAO) activities was looked for by measuring these enzyme activities in histologically normal small intestinal biopsies of 18 children. The range for disaccharidase activities expressed in U g-1 wet weight was 0.1-5.7, 7.1-36.7, and 2.3-8.5 for lactase, maltase, and sucrase, respectively. The range for DAO activities expressed in nmol h-1 g-1 wet weight was 202-974. Significant correlations were found between disaccharidase and DAO activities (lactase versus DAO: n = 17, r = 0.80, P < 0.001; maltase versus DAO: n = 18, r = 0.70, P < 0.001; sucrase versus DAO: n = 18, r = 0.55, P < 0.05). Our results further support the hypothesis that DAO is a marker of small intestinal functional integrity in children. [less ▲]

Purpose of review The purpose of this review is to update the knowledge on diarrhoea, a common problem in critically ill patients. Epidemiological data will be discussed, with special emphasis on diarrhoea in tube-fed patients and during antibiotic therapy. The possible preventive and therapeutic measures will be presented. Recent findings The need for concise definitions of diarrhoea was recently re-emphasized. The use of pump-driven continuous instead of intermittent enteral feeding is less often associated with diarrhoea. The discontinuation of enteral feeding during diarrhoea is not justified. Clostridium difficile-associated diarrhoea is frequent during antibiotic therapy with quinolones and cephalosporins. Formulas enriched with water-soluble fibres are probably effective to prevent diarrhoea, and promising data on the modulation of gut microflora with probiotics and prebiotics were recently released. Summary Diarrhoea is common in critically ill patients, especially when sepsis and hypoalbuminaemia are present, and during enteral feeding and antibiotic therapy. The management of diarrhoea includes generous hydration, compensation for the loss of electrolytes, antidiarrheal oral medications, the continuation of enteral feeding, and metronidazole or glycopeptides in the case of moderate to severe C. difficile colitis. The place of enteral formulas enriched with water-soluble fibres, probiotics and prebiotics is not yet fully defined. [less ▲]

Diaspirin Crosslinked Hemoglobin (Dclhb): Absence of Increased Free Radical Generation Following Administration in a Rabbit Model of Renal Ischemia and Reperfusion

In control rabbits, a renal ischemia of 60 min followed by 10 min of reperfusion resulted in an enhanced free radical production in cortical tissue, as assessed by a significant decrease of free glutathione (42%), protein-bound GSH (17%), and vitamin E (49%). In contrast, catalase or glutathione peroxidase activities were not affected by these experimental conditions. Free radical production in this model was also measured directly using electron spin resonance (ESR) spectroscopy associated with a PBN (alpha-phenyl N-tert-butyl-nitrone) spin trap agent in the venous blood arising from the ischemic kidney. The signal consisted of a triplet of doublets. In contrast, no signal could be detected in control blood samples taken prior to inducing ischemia. The burst of free radical production occurred in the early phase after restoration of flow in the kidneys rendered ischemic, as evidenced by a signal of weak intensity which generally appeared within the third minute after reperfusion and progressively increased to form a well-defined asymmetric signal following 10 min of reperfusion. The precise nature of free radicals trapped by the PBN agent remains, however, to be elucidated, but analysis of the coupling constants (aN = 14.5-15 G; a beta H = 2.5-3 G) and asymmetry of the central doublets suggests that the ESR signal may arise from a nitorxy-radical adduct resulting from the spin trapping by PBN of both oxygen- or carbon-centered radicals of lipid origin. As evidenced by both direct and indirect measurements, exchange of rabbit blood immediately after inducing renal ischemia with 30 ml/kg of Diaspirin Crosslinked Hemoglobin (7.5 g/dl in lactated electrolyte) or human serum albumin (7.5 g/dl in lactated electrolyte) did not exacerbate free radical production mediated by an ischemia reperfusion phenomenon, a typical situation found in a resuscitation setting.

Diáspora y voto en el exterior. La participación política de los emigrantes bolivianos en las elecciones de su país de origen

A nivel internacional, 115 países permiten que sus ciudadanos en el exterior ejerzan el derecho de participar en las elecciones de su país de origen. A pesar del desarrollo de la literatura sobre transnacionalismo político, el impacto del voto en el exterior sobre las relaciones entre emigrante, país de origen y país de residencia permanece desconocido. A través del caso de las elecciones presidenciales bolivianas del 6 de diciembre 2009, este libro discute las motivaciones de los estados expulsores por otorgar el derecho de votar a sus emigrantes, las variaciones en el uso de este derecho por los emigrantes según los lugares de destino y el impacto de este voto sobre el empoderamiento de los emigrantes en las sociedades de origen y de residencia. Los resultados presentados en este libro se basan en la observación del proceso electoral en el exterior, en entrevistas en profundidad conducidas con emigrantes y en más de 300 encuestas con electores bolivianos realizadas en las ciudades de Madrid, Buenos Aires, San Pablo y Nueva York.

Diastematomyelia is a relatively rare congenital abnormality presenting as a sagittal separation of the spinal cord. Although cases of diastematomyelia have been previously reported, fully documented approaches by both prenatal and postnatal diagnostic workup are rare in the literature. We present a fully studied case of diastematomyelia type I investigated by prenatal US and MRI and postnatal US, MRI and radiography. [less ▲]
