Parkinson's disease (PD) is the most common neurodegenerative movement disorder, and its causes remain unknown. A major hallmark of the disease is the increasing presence of aggregated alpha-synuclein (aSyn). Furthermore, there is a solid consensus on iron (Fe) accumulation in several regions of PD brains during disease progression. In our study, we focused on the interaction of Fe and aggregating aSyn in vivo in a transgenic mouse model overexpressing human aSyn bearing the A53T mutation (prnp.aSyn.A53T). We utilized a neonatal iron-feeding model to exacerbate the motor phenotype of the transgenic mouse model...

Mitchell-Riley syndrome/Martinez-Frias syndrome (MRS/MFS) is a rare, autosomal recessive disorder with multisystem involvement and poor prognosis. Most reported cases have been associated with homozygous or compound heterozygous mutations in the RFX6 gene, a transcriptional regulatory factor for pancreatic morphogenesis. Given the limited number of reported cases, the syndrome may be under-recognized. When the particular phenotype of MFS includes a mutation on the RFX6 gene and neonatal diabetes, it has been called Mitchell-Riley syndrome...

Idiopathic pulmonary hemosiderosis (IPH) is a rare complex entity characterized clinically by acute or recurrent episodes of hemoptysis secondary to diffuse alveolar hemorrhage. The radiographic features are variable, including diffuse alveolar-type infiltrates, and interstitial reticular and micronodular patterns. We describe a 3-week-old infant presenting with hemoptysis and moderate respiratory distress. Idiopathic pulmonary hemosiderosis was the first working diagnosis at the Emergency Department and was confirmed, 2 weeks later, by histological studies (bronchoalveolar lavage)...

BACKGROUND AND OBJECTIVES: Cholestasis affects 50% of extremely low-birth-weight infants. Its etiology remains poorly understood and the extent of liver injury in these infants is unclear. The premature baboon model provides an opportunity to study neonatal liver disease. We characterize hepatic histopathologic changes in this model. METHODS: Archival tissue and data were obtained from the Southwest Foundation for Biomedical Research Primate Center, San Antonio, TX...

α-Thalassemia mutations affect up to 5% of the world's population. The clinical spectrum ranges from an asymptomatic condition to a fatal in utero disease. Hemoglobin H disease results from mutations of three α-globin genes. Deletional forms result in a relatively mild anemia, whereas nondeletional mutations result in a moderate to severe disease characterized by ineffective erythropoiesis, recurrent transfusions, and growth delay. Hemosiderosis develops secondary to increased iron absorption, as well as transfusion burden...

Our study describes a novel phenotype in a series of nine Saudi patients with lactic acidosis, from four consanguineous families three of which are related. Detailed genetic studies including linkage, homozygosity mapping and targeted sequencing identified a causative mutation in the BCS1L gene. All affected members of the families have an identical mutation in this gene, mutations of which are recognized causes of Björnstad syndrome, GRACILE syndrome and a syndrome of neonatal tubulopathy, encephalopathy, and liver failure (MIM 606104) leading to isolated mitochondrial respiratory chain complex III deficiency...

A male infant born prematurely at 31 weeks of gestation weighed 789 g and had mildly brown-colored oral/tracheal aspirates at delivery. The amniotic fluid was also discolored, and its index was below 5. The patient died of hypoxemic respiratory and cardiac failure 2 hours after birth. The maternal profiles showed placenta previa and intrauterine growth restriction (IUGR) at 22 weeks of gestation, and revealed recurrent episodes of antenatal and substantial vaginal bleeding and oligohydramnios, indicating chronic abruption-oligohydramnios sequence...

Bronchopulmonary dysplasia (BPD) is characterized by simplified alveolarization and arrested vascular development of the lung with associated evidence of endothelial dysfunction, inflammation, increased oxidative damage, and iron deposition. Heme oxygenase-1 (HO-1) has been reported to be protective in the pathogenesis of diseases of inflammatory and oxidative etiology. Because HO-1 is involved in the response to oxidative stress produced by hyperoxia and is critical for cellular heme and iron homeostasis, it could play a protective role in BPD...

UNLABELLED: Mitochondrial dysfunction is an important cause for neonatal liver disease. Disruption of genes encoding oxidative phosphorylation (OXPHOS) components usually causes embryonic lethality, and thus few disease models are available. We developed a mouse model for GRACILE syndrome, a neonatal mitochondrial disease with liver and kidney involvement, caused by a homozygous BCS1L mutation (232A>G). This gene encodes a chaperone required for incorporation of Rieske iron-sulfur protein (RISP) into complex III of respiratory chain...

OBJECTIVE: To assess the potential role of MR imaging in the diagnosis of fetal liver iron overload. METHODS: We reviewed seven cases of abnormal liver signal in fetuses referred to MR imaging in a context of suspected congenital infection (n = 2), digestive tract anomalies (n = 3) and hydrops fetalis (n = 2). The average GA of the fetuses was 31 weeks. The antenatal diagnoses were compared with histological data (n = 6) and postnatal work-up (n = 1). RESULTS: Magnetic resonance imaging demonstrated unexpected abnormal fetal liver signal suggestive of iron overload in all cases...

Alpha thalassemia, the most common genetic disorder of hemoglobin synthesis, affects up to 5% of the world's population. It represents a group of conditions with reduced or absent synthesis of one to all four of alpha globin genes. Deletional or nondeletional mutations occur on chromosome 16. Its severity ranges from asymptomatic to fatal in utero. Hemoglobin H disease, a mutation of three alpha globin genes, is more severe than previously recognized. Anemia, hypersplenism, hemosiderosis, growth failure, and osteoporosis are commonly noted as the patient ages...

Liver failure in neonates is a rare but often fatal disease. Trisomy 21 is not usually associated with significant infantile liver disease. If present, hepatic dysfunction in an infant with Trisomy 21 is likely to be attributed to transient myeloproliferative disorder with hepatic infiltration by hematopoietic elements and may be associated with secondary hemosiderosis. A less commonly recognized cause of liver failure in neonates with Trisomy 21 is neonatal hemochromatosis (NH); this association has been reported in nine cases of Trisomy 21 in literature...

AIMS: To ascertain the incidence and to review the obstetric and neonatal correlates of placental haemosiderosis. Secondly, to determine if placental haemosiderosis is due to blood contamination during placental handling. METHODS: One hundred consecutive singleton placentas with and 113 consecutive singleton placentas from uncomplicated pregnancies without an indication for pathological examination were stained for iron to detect haemosiderosis in the membranes, chorionic plate and/or basal plate...

Neonatal hemochromatosis (NH) is a severe disease of fetal or perinatal onset, in which iron deposition occurs within hepatic and extrahepatic sites without involving the reticuloendothelial system. Labial minor salivary gland biopsy has been suggested as a diagnostic adjunct in patients suspected of having NH, as hemosiderin accumulates in acinar epithelial cells. Prior to this salivary gland pathology, a diagnosis of NH was often delayed, rendered only after the usual causes of neonatal liver failure had been excluded...
