1277 To the Editor: Transoesophageal echocardiography (TEE) plays an important role in monitoring, guiding, and evaluating the surgical repair of congenital heart disease (CHD).[1,2] However, the large size of the currently available TEE probes limits their application in pediatric cases, especially in small infants. Recently, a miniaturized micro‐TEE probe compatible in neonates has been intro...
It is known that if x is a real residue character modulo k with x(p) = — 1 k n for the first five primes p, then the corresponding Fekete polynomial £„=j X(n)x changes sign on (0, 1). In this paper it is shown that the condition that x(p) be — 1 for the first four primes p is not sufficient to guarantee such a sign change. More specifically, if x ¡s the real nonprincipal character modulo either...

The relation of language and emotion in development is most often thought about in terms of how language describes emotional experiences with words that name different feelings. However, children typically do not begin to use these words until language development is well underway, at approximately 2 years of age. Given the relatively small number of words for naming feelings and emotions, and ...
In a recent paper, Horder and colleagues (Horder et al., 2010, J Psychopharmacol 25: 1277-1288) have suggested that the mainproblem in the Kirsch analysis is methodological. We argue that the results are similar irrespective of the method used. In our opinion the data suggest that placebo and drug effects are non-additive: antidepressants act independently of depression severity, while the plac...
This text is an analysis of a preventive medical work, Liber de conservanda sanitate, composed in the thirteenth century by the Portuguese physician and doctor, Peter of Spain (?1210-1277). His work enables us to look at the conceptions of health and hygiene and understand the social role of university physicians in medieval preventive medicine. The work constantly displays the notion of the ba...
