Congenital high airway obstruction syndrome is a rare fetal anomaly with characteristic constellation of prenatal findings on ultrasound and MRI. The typical triad of imaging features are enlarged and echogenic lungs, flattening or inversion of diaphragm and fetal hydrops. Early prenatal recognition of congenital high airway obstruction syndrome by ultrasound and/or MRI is mandatory for the appropriate perinatal management. We report a case of a male fetus with typical imaging findings of congenital high airway obstruction syndrome on ultrasound and MRI at 19 weeks of gestation...

Previous researchers have documented that probiotic bacteria can have anti-obesity effects on mice fed a high fat diet (HFD) and improve metabolic syndrome. The beneficial effects of the probiotic bacteria are suggested to be strain dependent. In this study, two candidate lactobacteria strains, Lactobacillus casei IBS041, Lactobacillus acidophilus AD031 and two bifidobacteria strains, Bifidobacterium bifidum BGN4 and Bifidobacterium longum BORI, were individually administered to HFD-fed mice for 8 weeks. B...

Zika Virus (ZIKV), previously the cause of only rare and sporadic human infections, is now considered a Public Health Emergency of International Concern. Over the past two years, ZIKV has become a pandemic encompassing much of the Americas. ZIKV is now proven to cause microcephaly and ophthalmic anomalies in the newborn. Hydrops fetalis, developmental delay, and other anomalies are increasingly being attributed to ZIKV infection in fetuses and neonates. Sequelae of congenital infection and rapid spread of ZIKV throughout the Americas has catapulted Zika virus concerns to the forefront of the medical community...

BACKGROUND: maternal alloimmunization to fetal red blood cell antigens is a major cause of fetal anemia, which in untreated cases can lead to hydrops and perinatal death. The cornerstone of the management during pregnancy is intrauterine intravascular blood transfusion. Although this procedure is considered to be relatively safe, (procedure-related) complications continue to occur. OBJECTIVES: to evaluate procedure-related complications and perinatal loss rates of intrauterine transfusion and changes over time, aiming to identify factors leading to improved outcome...

Hb Zurich-Albisrieden [HBA2: c.178G > C; α59(E8)Gly→Arg (α2)] is a rare nondeletional α-thalassemia (α-thal) that results from a nucleotide substitution at codon 59 of the α2-globin gene. In this report, we present a fetus with cardiomegaly, enlarged placenta and increased middle cerebral artery-peak systolic velocity (MCA-PSV) at 25 weeks' gestation. Fetal blood sampling revealed the severe anemia [hemoglobin (Hb) level being 5.5 g/dL] and Hb H (β4) disease-like hematological findings with Hb Bart's (γ4) level of 30...

CONCLUSION: The data indicate important roles for phosphodiesterase (PDE) 3, 4, 5, and related cAMP and cGMP pools in the regulation of inner ear fluid homeostasis. Thus, dysfunction of these enzymes might contribute to pathologies of the inner ear. OBJECTIVE: The mechanisms underlying endolymphatic hydrops, a hallmark of inner ear dysfunction, are not known in detail; however, altered balance in cAMP and cGMP signaling systems appears to be involved. Key components of these systems are PDEs, enzymes that modulate the amplitude, duration, termination, and specificity of cAMP and cGMP signaling...

Context .- The placenta is an important component in understanding the fetal response to intrauterine Zika virus infection, but the pathologic changes in this organ remain largely unknown. Hofbauer cells are fetal-derived macrophages normally present in the chorionic villous stroma. They have been implicated in a variety of physiological and pathologic processes, in particular involving infectious agents. Objectives .- To characterize the fetal and maternal responses and viral localization in the placenta following Zika virus transmission to an 11 weeks' gestation fetus...

CONCLUSIONS: The presence of endolymphatic hydrops (EH) in the vestibule on magnetic resonance imaging (MRI) might be a high-risk factor for complications in cases that are candidates for stapes surgery. OBJECTIVE: Pre-operative detection of EH could be valuable in cases that are candidates for stapes surgery to prevent unpredictable complications following surgery. Pre-operative MRI findings and post-operative findings following stapes surgery were compared to evaluate the efficacy of such MRI evaluation for the management of cases with otosclerosis...

We describe a case of absent aortic and pulmonary valves, diagnosed at 16.4 weeks of gestation. Fetal echocardiography showed cardiomegaly with dilated both ventricles. No valve leaflets were observed in the aorta and pulmonary artery, and a typical to-and-fro flow pattern was noted in both great arteries on color Doppler imaging. Fetal hydrops was also detected. Follow-up ultrasonographic evaluation at 19 weeks demonstrated intrauterine fetal death. Postmortem autopsy revealed the absence of both aortic and pulmonary valve leaflets...
