Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1118, 43 pp. Uppsala. ISBN 91554-5225-6. Amniocentesis (AC) and chorionic villus sampling (CVS) are the principal methods for fetal karyotyping. The aim of this thesis was to evaluate...

Inadequate evaluation of vaccine coverage after mass vaccination campaigns, such as used in national measles control programmes, can lead to inappropriate public health responses. Overestimation of vaccination coverage may leave populations at risk, whilst underestimation can lead to unnecessary catch-up campaigns. The problem is more complex in large urban areas where vaccination coverage may ...

Chorionic villus sampling (CVS) and amniocentesis are prenatal diagnostic procedures that are performed to detect fetal abnormalities. In 1991, concerns about the relative safety of these procedures arose after reports were published that described a possible association between CVS and birth defects in infants. Subsequent studies support the hypothesis that CVS can cause transverse limb defici...

leukocyte adhesion deficiency type-1(lad-1) is one of the autosomal recessive immunodeficiency diseases that results from mutation in integrin beta 2 (itgb2) gene. the aim of this study was to investigate molecular prenatal diagnosis of lad-1. four pregnant women with five fetuses (one twin fetus) with clinical and laboratory diagnosis of lad-1 in their previous children were studied. the chori...

Low measles vaccination coverage (VC) leads to recurrent epidemics in many African countries. We describe VC before and after late reinforcement of vaccination activities during a measles epidemic in Niamey, Niger (2003-2004) assessed by Lot Quality Assurance Sampling (LQAS). Neighborhoods of Niamey were grouped into 46 lots based on geographic proximity and population homogeneity. Before reinf...

PURPOSE Amniocentesis (AC) and chorionic villus sampling (CVS) play an important role in the diagnosis of genetic anomalies. The aim of this study was to evaluate presentable numbers of procedure-related complications of genetic interventions in a tertiary referral hospital. MATERIALS AND METHODS The pregnancy outcome of women who underwent genetic AC or CVS during 2003-2010 at the Department...

Human cytomegalovirus (CMV) is the leading cause of prenatal viral infection. Affected infants may suffer intrauterine growth retardation and serious neurologic impairment. Analysis of spontaneously aborted conceptuses shows that CMV infects the placenta before the embryo or fetus. In the human hemochorial placenta, maternal blood directly contacts syncytiotrophoblasts that cover chorionic vill...

Cytogenetic analysis is a crucial tool of prenatal diagnosis. The ability to rapidly detect aneuploidy and identify small structural abnormalities of foetal chromosomes has been greatly improved by the use of molecular cytogenetic technologies. Microarray-based Comparative Genomic Hybridization (aCGH) has been recently employed in postnatal diagnosis of cryptic chromosomal aberrations, but use ...

A large number of investigators have studied the general histology of the chorionic villus and decidua parietalis but few of them have been particularly concerned with the ccllular components which may be associated with the process of secretion. In 1916, de Kervily published two papers in which he described in considerable detail the cytology of the human chorionic villus. Many of his observat...
