hemoglobinopathies/edema

This was a retrospective case-control study of hydrops fetalis due to Bart hemoglobinopathy at Ramathibodi Hospital between 1978-1987. The incidence was 0.61 per 1,000 deliveries. Hydrops fetalis tend to go into labour prematurely with smaller fetuses and larger placentae. When compared with the

Alpha-thalassemia is the most common cause of hydrops fetalis among Southeast Asians. With the recent influx of Southeast Asian refugees and the rapidly growing Filipino population this will become an increasingly important obstetric problem in the United States. Homozygous alpha-thalassemia, or

Hydrops fetalis is a serious condition which indicates poor prognosis for the affected fetus. Although the incidence of isoimmune hydrops fetalis has decreased markedly, nonimmune hydrops fetalis cases have been more frequently reported. Nonimmune-mediated hydrops can be caused by

Northeastern (NE) Thailand is one of the areas with a prevalence of thalassemias and hemoglobinopathies. Data on the prevalence of the diseases in minorities in the region has been limited. This study aimed to survey the thalassemias and hemoglobinopathies that take into account ethnicity. Four

Primate erythroparvovirus 1 (parvovirus B19) is a member of the Erythrovirus genus of the Parvoviridae family and it is one of the few members of the family known to be pathogenic in human. B19 infection is common and widespread with the virus being associated with numerous rheumatologic and

Massive hepatomegaly is a common finding in hydrops fetalis (HF) arising from hemoglobinopathies. It has been suggested that extramedullary hematopoiesis, which is markedly increased in response to anemia, plays a principal role in hepatomegaly via sinusoidal obstruction and distortion of the

OBJECTIVE To provide recommendations to physicians, midwives, genetic counsellors, and clinical laboratory scientists involved in pre-conceptional or prenatal care regarding carrier screening for thalassemia and hemoglobinopathies (e.g., sickle cell anemia and other qualitative hemoglobin

Thalassemia syndromes and hemoglobinopathies are of clinical genetic significance because of the severity of the sequelae associated with particular genetic constitutions in these conditions, their occurrence at high frequencies in certain populations of Mediterranean, African, and Asian origin, and

Hemoglobin Taybe is an unstable alpha-chain hemoglobin variant caused by a deletion of a threonine residue at codon 38 or 39 of the alpha-1 globin chain. We describe preterm infant triplets born with hydrops fetalis and anemia who were found by DNA analysis to be homozygous for hemoglobin Taybe. All

Fetoplacental hydrops is the final stage of several pathological conditions in which the placenta and umbilical cord become edematous and the fetus develops an anasarcatic state characterized by an excessive accumulation of extravascular fluids in at least two serous cavities of the body. It is a

We describe a fetus at 24 ^3/7 weeks' gestation that showed ultrasound evidence of anemia, hydrops, and severe growth restriction. Both parents were known to be cis heterozygous carriers for SEA α-thalassemia deletion (αα/-). Cordocentesis confirmed fetal anemia and homozygous

Alpha-thalassemia is an autosomal recessive genetic disease as well as a relatively common hemoglobinopathy. Severe alpha-thalassemia (also known as Hb Bart's Hydrops fetalis syndrome) and intermediate alpha-thalassemia (also known as Hb H disease) are among the most common birth defects in southern

Homozygous alpha-thalassemia major, or Bart's hemoglobinopathy, is the most common etiology of nonimmune hydrops in those of Oriental descent. The prenatal diagnosis can now be made utilizing DNA hybridization technique from fetal cells obtained by either amniocentesis or chorionic villus sampling.
