As long-term survival is high for children and young adults diagnosed with leukemia and lymphoma, delineating maternal, fetal and offspring health risks is important to their family planning. This systematic review examined data comparing these health risks between leukemia and lymphoma survivors and women without a history of cancer. Following a search of Embase, PubMed, CINAHL, Cochrane, and Web of Science, 142 articles were screened and 18 were included in this review. No higher risks of spontaneous abortion, maternal diabetes and anemia, stillbirth, birth defects, or childhood cancer in offspring were observed in survivors compared to controls...

Human parvovirus B19 (B19V) causes a number of skin exanthemas and has been related to both cutaneous and systemic diseases. Tropism of the virus for the rapidly proliferating erythroid progenitor cells in the bone marrow and fetal liver explains the pathogenesis of anemia and fetal hydrops. The cutaneous lesions of erythema infectiosum and other B19V-related exanthemas have been attributed to the deposition of immune complexes in the skin. We report on the immunohistochemical detection of B19V protein in the cytoplasm of dermal endothelial cells in a case of periflexural exanthema in a 28-year-old woman...

Erf is a ubiquitously expressed ets-DNA-binding containing transcriptional repressor. Erf haploinsufficiency causes craniosynostosis in human and mice, while its absence in mice leads to failed chorioallantoic fusion and death at E10.5. In this study, we show that Erf is required in all three waves of embryonic hematopoiesis. Mice lacking Erf in embryo proper exhibited severe anemia and died around embryonic day (E) 14.5. Erf epiblast specific knockout embryos had reduced numbers of circulating blood cells from E9...

Evaluation of the fetal heart at 11-13 + 6 weeks of gestation is indicated for women with a family history of congenital heart defects (CHD), a previous child with CDH, or an ultrasound finding associated with cardiac anomalies. The accuracy for early detection of CHD is highly related to the experience of the operator. The 4-chamber view and outflow tracts are the most important planes for identification of an abnormal heart, and can be obtained in the majority of fetuses from 11 weeks of gestation onward...

Sickle cell anemia (SCA) is characterized by chronic hemolysis, severe vasoocclusive crises (VOCs), and recurrent often severe infections. A cohort of 95 SCA pediatric patients was the background for genotype-to-phenotype association of the patient's infectious disease phenotype and three non-coding polymorphic regions of the TLR2 gene, the -196 to -174 indel, SNP rs4696480, and a (GT)n short tandem repeat. The infectious subphenotypes included (A) recurrent respiratory infections and (B) severe bacterial infection at least once during the patient's follow-up...

Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a rare disease of functional obstruction affecting the bladder and intestines, characterized by a markedly distended bladder, microcolon, and decreased or absent intestinal peristalsis. Afflicted neonates have very poor prognosis, usually with fatal outcomes in first days to months of life. Placental fetal thrombotic vasculopathy (FTV) is a thrombo-occlusive disorder of the chorionic plate and fetal circulation. Herein, we describe an undocumented association of MMIHS and placental FTV...

Coinfections contribute significantly to diagnostic challenges of acute febrile illnesses, especially in endemic areas. The confusion caused by overlapping clinical features impedes timely management. Herein, we report an unusual, previously unreported case of a pregnant woman suffering from a coinfection of scrub typhus and hepatitis E virus. A 25-year-old, 31-week pregnant woman presented with jaundice for 5 days and altered sensorium for 2 days. She had features of both viral acute liver failure (ALF) and tropical infections mimicking ALF, including hyperbilirubinemia, coagulopathy, anemia, thrombocytopenia, intravascular hemolysis, and hepatosplenomegaly...

REVIEW
Swee Lay Thein
The remarkable phenotypic diversity of β thalassemia that range from severe anemia and transfusion-dependency, to a clinically asymptomatic state exemplifies how a spectrum of disease severity can be generated in single gene disorders. While the genetic basis for β thalassemia, and how severity of the anemia could be modified at different levels of its pathophysiology have been well documented, therapy remains largely supportive with bone marrow transplant being the only cure. Identification of the genetic variants modifying fetal hemoglobin (HbF) production in combination with α globin genotype provide some prediction of disease severity for β thalassemia but generation of a personalized genetic risk score to inform prognosis and guide management requires a larger panel of genetic modifiers yet to be discovered...

INTRODUCTION: Despite prophylaxis, a small proportion of RhD-negative women may develop anti-D antibodies after a sensitizing event occurring during pregnancy or delivery of a D-positive baby. Intrauterine transfusion (IUT) is the treatment of choice in case of fetal anemia, but it cannot be performed early during pregnancy. Combined treatment with therapeutic plasma-exchange (TPE) and intravenous immunoglobulin (IVIG) can avoid or delay IUT. Immunoadsorption (IA) could represent a more effective treatment in selected cases...

  We experienced a 6-year-old girl diagnosed with mevalonate kinase deficiency (MKD) who had cholestasis, anemia, and elevated inflammatory markers in neonatal period. She was admitted to our hospital because of fever and elevated inflammatory markers at 5 years 11months of age. Without using antibiotics, the fever and the inflammatory markers were spontaneously resolved. MKD was suspected from elevated serum IgD level and the recurrent febrile attacks. The genetic test revealed heterozygous mutation of p...

OBJECTIVE: Fetal hemolytic disease is a common cause of fetal hydrops and fetal morbidity and mortality. Despite its relatively low frequency, the anti-M IgG antibody is one of the causes of severe fetal anemia and intrauterine death; only a few cases have been reported. CASE REPORT: This is a case of a pregnant woman with a history of three intrauterine deaths. A diagnosis of severe fetal anemia attributed to anti-M alloimmunization was confirmed in her fifth pregnancy...

Twin-twin transfusion syndrome is a complication of monochorionic-diamniotic placentation. Should one twin die, ≈30% of co-twins will also die, and if they survive, ≈30% experience severe morbidity rates, each believed secondary to hemorrhage of the co-twin into the deceased twin. We report apparently the first ultrasound-documented case of perimortem hemorrhage in twin-twin transfusion syndrome and its treatment by emergent ultrasound-guided percutaneous cord occlusion followed by percutaneous fetal intravascular transfusion...

BACKGROUND: The Monocyte Monolayer Assay (MMA) is an in vitro simulation of red blood cell (RBC) alloantibody behavior. It has been classically applied to predict the risks of post-transfusion hemolytic reactions when transfusing incompatible RBC units. Quantifying erythrophagocytosis by MMA may be an interesting option for situations where there is doubt whether a RBC autoantibody is mediating significant hemolysis. Here, we present three situations involving RBC autoantibodies in which the MMA was decisive for clarifying the diagnosis and choosing the best clinical treatment...
