Objective - To evaluate the neurologic morbidity after orthotopic heart transplantation (OHT), we examined consecutive Chagas' (Ch) and non-Chagas' (NCh) patients, before and after surgery. Material and methods - We undertook neurological and neuropsychological evaluations in Ch and NCh patients with end-stage cardiac failure, from September 1993 to September 1995. Results - Of 10 Ch patients (mean age=33.6 years; 7 male; mean follow-up=10.8 months) and 13 NCh patients (mean age=50.9 years; 12 male; mean follow-up=15 months) 3 died (rejection and sepsis) without neurologic symptoms. Neurologic complications occurred in 4 Ch and 5 NCh patients. Two Ch patients had skin and myocardial Chagas' reactivation successfully treated, without CNS involvement. NPS performance and return to work rates were similar in both groups. Conclusions - Although Ch patients are potentially at a higher risk of Trypanosoma cruzi reactivation, in addition to all known neurologic complications of OHT, early neurologic complications detected in this sample were similar in Ch and NCh patients and could not be specifically related to Chagas' disease. 相似文献

In recent decades, there has been a dramatic increase in unhealthy weight for both children and adults. The Canadian standard of living has changed in favour of more easily prepared, calorie-dense foods and sedentary practices. Many family characteristics have also changed over the past 50 years. More Canadian families are living in disadvantaged situations, forecasting a host of unhealthy behaviours and attitudes in adults. The poor are not only getting poorer, they are also becoming heavier. Children from disadvantaged families seem to be leading the trend in increasing prevalence of unhealthy weight. Because they live in neighbourhoods that are perceived as unsafe, these children are likely spending more time indoors. This is associated with watching more television, which not only displaces other forms of educational and active entertainment but also places them at risk of learning inaccurate information about proper eating. Social science research helps identify factors contributing most to the rise in excess weight within this population, thus providing essential clues for effective approaches to its eradication. 相似文献

In a series of 51 children presenting with an accidental caustic burn, symptoms were analysed for their predictive value of significant i.e. necrotizing oesophageal lesions (grade II or III). For the whole group, the incidence of significant oesophageal lesions was 37%. Vomiting and/or respiratory distress were associated with high incidence of significant oesophageal burn (84% and 75% respectively). The particular location of each caustic burn was analysed for its association with caustic burns at other anatomical sites. Of the 18 patients with a laryngeal burn, 72% also had a grade II or III oesophageal burn. The 19 patients with a grade II or III oesophageal burn and the 18 patients with a laryngeal burn, all had lesions at other sites. In the group of 19 patients with a caustic lesion limited to one site, only 1 patient showed mild oesophagitis (grade I) without late sequelae. 相似文献

Percutaneous transcatheter occlusion of coronary artery fistulas using detachable balloons 总被引:1,自引:0,他引:1
Three pediatric patients underwent successful transcatheter coronary artery fistula occlusion using the Debrun system. This
latex balloon system offers several advantages over other occlusion systems. First, the balloon delivery and release is controlled.
Second, “test occlusions” can be performed that allow simultaneous balloon inflation, coronary cineangiography, and electrocardiographic
monitoring. Third, because the balloons are flow-directed, they are easily positioned in properly chosen locations. Finally,
the balloons can be constructed to suit the size of the fistula. In this study, two patients received only one balloon; in
the other patient two balloons were placed in the same fistula. All fistulas drained into either the right atrium or ventricle
and were successfully occluded. After a follow-up period of up to 3 years, no local or systemic reactions to the balloons
were recognized. We conclude that detachable balloon occlusion of coronary artery fistulas is a safe, effective alternative
to surgical ligation in selected pediatric patients. 相似文献

测定7例心力衰竭患儿及44例健康儿童血浆心钠素浓度,发现心力衰竭患儿血浆心钠素浓度较健康儿童增加,且与病情轻重有关,心力衰竭程度越重,心钠素浓度越高,此系心脏通过降低心脏前、后负荷以改善心功能的代偿机制。2个月至12岁健康儿童血浆心钠素水平不受性别及年龄的影响。 相似文献

Neural networks are models of the brain and have been used within Artificial Intelligence to provide alternative explanations
to the symbolic explanations of cognition in which one assumes that an intelligent system has certain explicit representations
of some aspect of the world and uses these in intelligent behavior. Obviously, if neural networks are indeed good models of
the brain, and give a satisfactory account of cognition, then they could be a valuable tool to neuroscientists. This article
gives a brief overview of the various neural network models, and critically reviews their status as models of the brain and
of cognition. 相似文献
