Plastination is in some cases unsuccessful. The goal of this work was to monitor, to describe and to analyse the reasons of S10 plastination method failure. We prepared the silicone-impregnated specimens using the standard silicone method S 10. The causes of bad preparation are numerous. Usual defects produced during plastination process are the changes in the bulk, the changes in the colour and other visible defects (e.g. deformations, spots on the organs surface). The frequent reasons for these defects are: unsuitable temperature, using of old bad fixed formaldehyde specimens and too long gas-curing procedure. The knowledge of reasons of unsuccessful plastination is important condition for achievement the good results.
SUMMARYBackground and Aim: Over the past 18 years, according to data from the Clinic of Plastic and Reconstructive Surgery, L. Pasteur University Hospital, there have been 493 cases of orofacial clefts (OC) reported in the area of Eastern Slovakia. The aim of this study was to map the occurrence of orofacial clefts reported in the area of Eastern Slovakia during the years 1996-2013. Also, we compared the occurrence of different types of clefts between the groups in relation to gender and ethnicity.
Methods and Results:The statistical analysis shows relationship between variables of location and gender and gender differences in the occurrence of various types of clefts. Moreover, in comparison with another study which analyzed the years 1985-2000 (1.29/10 3 live births), there was an increase in the incidence (1.42/10 3 live births) of OC in Eastern Slovakia. Conclusion: Our findings seem contradictive to similar studies which discuss ethnic differences in relation to OC. We recognize the relatively high occurrence of OC in Eastern Slovakia, and we link this phenomenon to several extrinsic factors, in particular socioeconomic status and embryotoxic factors.
Encephalocystocele is a developmental malformation characterized by brain herniation accompanied with extracranial cystic protrusion of the ventricular system. This nosological unit is often overlooked and insufficiently classified merely as encephalocele. Herein, two exceptionally clear cases of the parieto-occipital cranioschisis with encephalocystocele and congenital hydrocephalus of the lateral ventricles are documented with 2-dimensional/3-dimensional sonographic images and the corresponding MRI findings. In both cases, prenatal diagnosis was confirmed by autopsy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
