A Survey on the Use of Antibiotics in Greek Hospitals

Abstract

Of 15,819 patients hospitalized in Greek hospitals during the years 1969–1970, 6,690 (42.3%) received antibiotic treatment. Of those, 4,177 (62.%) received one antibiotic, and 2,513 (37.6%) two or more in combination. There was no difference between teaching hospitals of Athens and non-teaching hospitals of Athens and several provincial towns. A large number of authorities believe that a great number of antimicrobial drugs are prescribed needlessly. In view of the high frequency of adverse reactions and the high cost of these drugs, this is a matter of serious concern. In this brief report we publish the results of a survey on the use of the antimicrobial drugs in Greek hospitals.

Dipolar interactions and thermal stability of two-dimensional nanoparticle arrays

“…Then, future studies of two-dimensional systems should add the effects of dipolar interactions with the influence of disorder on relaxation, present for example when the anisotropy axes are randomly oriented, which is the usual case in self-assembled or epitaxial nanoparticle systems [32][33][34]. For the important case of perpendicular anisotropy, relevant for data storage, disorder can also be present in the intensities of local anisotropies [35,34]. Polydispersed assemblies with a distribution of grain volumes can also be straightforwardly considered within the present model [32,33].…”
