Abstract:Evaluation of cardiac structure is essential for definitive diagnosis of cardiac anomalies, which has significant implications in planning and implementing prenatal therapy. Congenital cardiac malformations are the most common anomalies encountered in pediatric clinics. The present study is aimed at analyzing various morphological and morphometric parameters of human fetal hearts by collecting heart specimens from dead and spontaneously aborted fetuses of various gestational ages. A total of 60 apparently normal dead aborted embryos and fetuses of both sexes and of 10 - 40 weeks gestational age were utilized for observing and measuring certain morphological and morphometric parameters of external body and external cardiac parameters. All the external body parameters and external cardiac parameters are moderately correlated except heart height and heart weight that were strongly correlated with body weight. Mean values of all parameters are increasing significantly with gestational age in trimester wise groups whereas in week wise group they are differing significantly. All the parameters are having significant strong positive correlation among each other. Heart height and heart weight were strongly correlated with body weight. The morphometric data and their innovative interpretation have immediate applications in both morphological and functional areas of cardiology, which is helpful in permanent clinical evaluation of fetal heart development.

Key words: Aborted fetuses, External fetal body dimensions, External cardiac parameters, Fetal heart height, Fetal heart weight.

Abstract: Objective : To evaluate the efficacy and safety of Tranexamic acid in the reduction of blood loss during and after caesarean section. This study was conducted during period of two years. Methods: This is a prospective and randomized study consisting of 200 patients undergoing caesarean section. This included 100 cases from study and 100 cases from control group. Both primigravida and primipara previous one caesarean section were included.

Abstract: The human placenta is the "Mirror of maternal and foetal status:" The human placenta is a Labyrinthine, Heamochorial, chorio-allantoic and deciduate organ. A term placenta was described by morton (1957) in multigravid female. The present study has been undertaken to study whether maternal and foetal causes for variation in morphometric study of placenta have any relevance with reported abnormalities the tremendous benefit will be achieved by solving above problems and paucity of much work in this part of North coastal Andhra Pradesh gave an impetus to take up the study of morphometric data of placenta

Abstract: The platform switching concept involves the reduction of the restoration abutment diameter with respect to the diameter of the dental implant.Crestal bone loss has been documented as one of the important factors that affect the long term prognosis of a dental implant. Platform switching for maintaining peri-implant bone levels has gained popularity among implant manufacturers over the last few years. However, the assumption that the inward shifting of the implant- abutment junction may preserve crestal bone was primarily based on serendipitous finding rather than scientific evidence.
