[Ultrasonographic twin peak sign]

JAKOBOVITS Ákos

[INTRODUCTION - Author describes ultrasonographic twin peak sign in order to differentiate dichorial-diamniotic from monochronic-diamnotic pregnancy in early gestation. In case of dichorial pregnancy the chorial tissue is forming a triangle shape. In case of monochorial twins the two amnion layers are forming a ”T” shape. CASE REPORT - The first case represents a dichorionic pregnancy, while the second case is an example of monochorionic placental formation. CONCLUSION - The twin peak sign has clinical significance, because dichorionic pregnancies carry less risk of gestational and labor complications.]

[Epidemiology, cost and economic impact of cerebral palsy in Hungary]

FEJES Melinda, VARGA Beatrix, HOLLÓDY Katalin

[Objective - The purpose of our communication was to determine the total cost of cerebral paretic patients in Hungary between 0 and 18 years and to assess their impact on the national budget. Methods - Based on the data of Borsod county we calculated the CP characteristics. The cost of CP was determined by routine care of individuals. Lost Parental Income and Tax were calculated on the basis of average earnings. The ratio of GDP, Health and Social Budget and Health Budget to CP is based on CP annual average cost and frequency. We have developed a repeatable computational model. Results - Of the risk groups, premature birth (30.97%), low birth weight (29.64%), perinatal asphyxia (19.47%) were the most common. Source is unknown of 37.61% of the cases. CP prevalence was 2.1‰. The two-sided (59.7%) and the one-sided (19.0%) spastic pareses dominated. The most serious form is the two-sided spastic paresis (42.5% GMFCS 3-5 degrees). Epilepsy was 22.0%, incontinence was 27%, mental involvement was 46%. Care for one child up to 18 years of age costs an average of 73 million HUF (€ 251,724). The lost family income was 27.36 million HUF (€ 94,345), and lost tax and health care contributions were 14.46 million HUF (€ 49,862). Additionally, 0.525% of the GDP, 0.88% of the full health and social budget and 1.83% of direct medical costs were spent for CP families. Conclusion - The cost of CP disease is significant. Costs can be reduced by improving primary prevention. From the perspective of the family and government, it is better to care for families so they can take care of their disabled children.]

[Cholesterol-lowering is not the Holy Grail, but neither is the work of the devil]

BAJNOK László

[Cholesterol-lowering statins are the most tested medications in respect of the effects and side-effects. Based on these, we can safely claim that most of the negative opinions about cholesterol-lowering are not realistic. It is not a panacea, but it is proven that around a 30% of cardio- and cerebrovascular risk reducation can be achieved by their regular taking, while the incidence of side effects and risks are at least one order of magnitude lower in each patient groups. For cholesterol, there is no “normal” lab threshold or low level, only “target values”, since the mean value in the general population is high in regard of atherosclerosis (the values measured at birth and among natural people can be considered normal). Let us appreciate the cholesterol- lowering medications because we do not have a large armamentarium!]

[About stem cells]

PAPP Csaba

[Stem cells are special cells of an organism that are capable to continuously renew themselves and, triggered by environmental effects, to differentiate and produce cells suitable for various functions. Due to their special characteristics, stem cells have an exciting potential to fulfil an old dream of physicians: to replace and regenerate damaged cells and tissues. Regenerative medicine has undoubtedly opened new vistas in medicine and provides hope for those with yet uncurable diseases. Here, we briefly describe different kinds of stem cells and their sources and discuss some of their experimental or clinical applications. Besides the bone marrow, which is now considered a traditional stem cell source, we present alternative sources. Among these, we pay special attention to the two stemcell sources that are important for obstetricians and gynaecologists: the umbilical cord (Wharton’s jelly) and the characteristics of the umbilical cord blood. We discuss some aspects of the storage of cord blood (”stem cell banking“) its potential use. Obstetricians and gynaecologists have an important role and a great responsibility in promoting the collection and, if necessary, the use of these stem cells. Communicating with patients and informing them about the their possible therapeutic applications stem cells is a part of this process as well as obtaining cord blood and preserving a segment of the cord. Obstetricians and gynaecologists should help to save as much as possible the umbilical cord and cord blood, which become ”redundant“ after birth but are a great source of multipotent mesenchymal and haemopoietic stem cells, which can be used in various fields of 21st-century medicine.]
