Laparotomic reposition of acute postpartal uterine inversion.

Acute uterine inversion is a rare but one of the most serious complications of childbirth. This condition is defined as the collapse of the fundus into the uterine cavity. Maternal mortality and morbidity are reported to be 41%. In the management of uterine inversion, early dia-gnosis, anti-shock measures and attempting manual repositioning as soon as possible are important. If the initial manual repositioning fails, it is necessary to proceed with surgical intervention. Administration of uterotonic agents is recommended after successful reposition. This recommendation helps uterine contraction, thereby preventing recurrence of the inversion. If reposition is repeatedly unsuccessful, then a hysterectomy may be necessary. The aim of this paper is to present a case report from our department.

Dynamics of Silurian Plants as Response to Climate Changes.

The most ancient macroscopic plants fossils are Early Silurian cooksonioid sporophytes from the volcanic islands of the peri-Gondwanan palaeoregion (the Barrandian area, Prague Basin, Czech Republic). However, available palynological, phylogenetic and geological evidence indicates that the history of plant terrestrialization is much longer and it is recently accepted that land floras, producing different types of spores, already were established in the Ordovician Period. Here we attempt to correlate Silurian floral development with environmental dynamics based on our data from the Prague Basin, but also to compile known data on a global scale. Spore-assemblage analysis clearly indicates a significant and almost exponential expansion of trilete-spore producing plants starting during the Wenlock Epoch, while cryptospore-producers, which dominated until the Telychian Age, were evolutionarily stagnate. Interestingly cryptospore vs. trilete-spore producers seem to react differentially to Silurian glaciations-trilete-spore producing plants react more sensitively to glacial cooling, showing a reduction in species numbers. Both our own and compiled data indicate highly terrestrialized, advanced Silurian land-plant assemblage/flora types with obviously great ability to resist different dry-land stress conditions. As previously suggested some authors, they seem to evolve on different palaeo continents into quite disjunct specific plant assemblages, certainly reflecting the different geological, geographical and climatic conditions to which they were subject.
