BACKGROUND Noninvasive genotyping of fetal RHD (Rh blood group, D antigen) can prevent the unnecessary administration of prophylactic anti-D to women carrying RHD-negative fetuses. We evaluated laboratory methods for such genotyping. METHODS Blood samples were collected in EDTA tubes and Streck® Cell-Free DNA™ blood collection tubes (Streck BCTs) from RHD-negative women (n = 46). Using Y-spec...
BACKGROUND Rheumatic Heart Disease (RHD) is amajor cause of cardiovascular morbidity and mortality in young individuals, in developing countries. Long term studies regarding natural history of RHD in Pakistan have not been reported in literature. We present our follow up observations on RHD patients at the end of 12 years since our first survey conducted in rural communities in 1994. METHODS ...
Antigens of the Rh blood group system are encoded by 2 homologous genes, RHD and RHCE, that produce 2 red cell membrane proteins. The D-negative phenotype is considered to result, almost invariably, from homozygosity for a complete deletion of RHD. The basis of all PCR tests for predicting fetal D phenotype from DNA obtained from amniocytes or maternal plasma is detection of the presence of RHD...
BackgroundPhysiological changes in pregnancy can precipitate decompensation women with pre-existing cardiac disease leading to suboptimal fetal outcome addition maternal risk. Many born congenital heart are living into childbearing years, and rheumatic (RHD) remains a significant problem within M?ori Pasifika communities New Zealand.AimsTo assess documentation of contraception advice pre-concep...
BACKGROUND Considering the limited accuracy of clinical examination for early diagnosis of rheumatic heart disease (RHD), echocardiography has emerged as an important epidemiological tool. The ideal setting for screening is yet to be defined. We aimed to evaluate the prevalence and pattern of latent RHD in schoolchildren (aged 5-18 years) and to compare effectiveness of screening between public...
AIMS To estimate the annual mortality and the cost of hospital admissions for acute rheumatic fever (ARF) and rheumatic heart disease (RHD) for New Zealand residents. METHODS Hospital admissions in 2000-2009 with a principal diagnosis of ARF or RHD (ICD9_AM 390-398; ICD10-AM I00-I099) and deaths in 2000-2007 with RHD as the underlying cause were obtained from routine statistics. The cost ...
BACKGROUND We investigated the efficacy of annular ligament reconstruction by suture anchor in the treatment of radial head dislocation (RHD) in children. METHOD A total of 20 RHD children nderwent annular ligament reconstruction surgery using suture anchor. Preoperative and postoperative elbow functions were evaluated according to Broberg and Morrey 100-point scale. Recovery of radial nerve ...
Objective Rheumatic heart disease (RHD) remains a major health problem in many low-income and middle-income countries. The use of echocardiographic imaging suggests that subclinical disease is far more widespread than previously appreciated, but little is known as to how these mild forms of RHD progress. We have determined the prevalence of subclinical RHD in a large group of schoolchildren in ...
BACKGROUND Rheumatic heart disease (RHD) is the commonest acquired heart disease in children worldwide but in Uganda, data is scarce regarding its morbidity and mortality. The disease has a progressive course and patients usually require valve repair/replacement in the future. OBJECTIVES To describe the frequency of echocardiographic valvular dysfunction in children with RHD To explore the re...
To determine which Rh-polypeptide genes are related to which Rh (rhesus) antigens, genomic DNAs prepared from donors of ten kinds of different Rh phenotypes were analysed by Southern hybridization method using two probes for the 5' moiety and 3' moiety of an Rh-polypeptide cDNA. A polymorphism for the Rh blood-group system was observed with BamHI, HindIII, PstI and EcoRI restriction endonucleas...
