In approximately 20% of individuals with Kagami-Ogata syndrome (KOS14, MIM 608149), characterized by a bell-shaped thorax with coat-hanger configuration of the ribs, joint contractures, abdominal wall defects and polyhydramnios during the pregnancy, the syndrome is caused by a maternal deletion of the imprinted gene cluster in chromosome 14q32.2. Most deletions reported so far included one or both of the differentially methylated regions (DMRs) - DLK1/MEG3 IG-DMR and MEG3-DMR.

This study aimed to provide a more comprehensive picture of the prevalence of autism spectrum disorder (ASD) in a geographic cohort of extremely preterm born adolescents by using established diagnostic instruments in addition to screening instruments. 53 participants passed a screening procedure with two screening instruments and a diagnostic evaluation with a semi-structured assessment and a parent interview. 28 % of the adolescents had a community based clinical diagnosis of ASD.

Design: Historical cohort study.
Setting: Thirty-two-bed neonatal intensive care unit (NICU) in a tertiary referral hospital.
A neonate who received vitamin K (VK) supplementation then developed severe late-onset bleeding with abnormal prothrombin time and activated partial thromboplastine time. The bleeding was corrected after intravenous VK. Molecular analysis of the gamma-glutamylcarboxylase gene revealed a heterozygous single nucleotide polymorphism, which decreases carboxylase activity and induces VK-dependent coagulation deficiency.

The purpose of this study is to calculate reference intervals for plasma and DBS citrulline concentrations in children and to examine the effect of age and gender.

Patients And Methods: 1099 NICU-admitted high-risk infants were assessed up to the corrected age of at least 12 months. CP was categorized relative to subtype, distribution and severity.
The aim of the study is to evaluate the predictive value of various types of brain injury detected by ultrasound in the neonatal period for the occurrence of cerebral palsy and its characteristics in a large cohort of high-risk infants. Thousand twenty-one consecutively NICU-admitted high-risk infants were assessed up to the corrected age of at least 2 years. Cerebral palsy (CP) was categorised into spastic or non-spastic, bilateral or unilateral and mild, moderate or severe CP.

Four hundred sixty-one children with a birthweight > or = 1250 g and GA > or = 30 weeks with a complicated neonatal period and/or brain injury on serial cerebral ultrasound were selectively followed at the regional Center for Developmental Disorders. The children were divided into a preterm and term group.

Methods: The study included a clinical examination and a standardized neurologic and developmental assessment. Disabilities were defined by international criteria.
We report three siblings, two of whom had a neuropathological study, with a new subtype of congenital ponto-cerebellar atrophy (PCH). In addition to the brain stem and cerebellar anomalies common to all types of this heterogeneous condition, there were unique developmental defects in the telencephalon: absence of the claustrum, diffuse cortical changes particularly in the insula and an extremely small brain. In an attempt to shed some light on the pathogenesis of this developmental disorder, we have analyzed the pattern of brain stem and cerebellar abnormalities in ours and in previously reported patients with PCH, to possibly distinguish primary from secondary effects of the mutant gene upon the cerebellar circuitry, and compared our patients' cerebellar and cerebral defects to those of some other human brain malformations and to mutant mice with both hindbrain and forebrain anomalies.

Consequently, attention should be given to the potential of risk to the fetus of BPD in women of childbearing age. We present the case of a pregnant woman who had undergone BPD 8 years previously, with documented vitamin A deficiency, who gave birth to a child with bilateral microphthalmia.

Most cases are sporadic with unknown incidence. Before attempts of fetoscopic fetal salvage or ex utero intrapartum treatment (EXIT) are considered, additional malformations must be carefully excluded as CHAOS may be part of various monogenic conditions or chromosomal disorders.

Hyponatremia as a result of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is a relatively common serious side effect of the use of SSRIs in (mostly elderly) adults. Severe hyponatremia as a result of an SIADH is proposed here as part of a neonatal serotonin toxicity syndrome in a newborn infant who was exposed prenatally to an SSRI.

Excessive urinary iodine excretion and borderline hyperthyrotropinaemia were observed in the infant. Moreover, crossing of the fetal blood-brain barrier was demonstrated by detection of the angiographic material in CSF and thus direct fetal neurotoxic effects cannot be excluded.

Structural insights into formation of the complex between the ubiquitous thiol-disulfide oxidoreductase thioredoxin and its oxidized substrate are under-documented owing to its entropical instability. In vitro, it is possible via a reaction with 5,5'-dithiobis-(2-nitrobenzoic acid) to make a stable mixed-disulfide complex between thioredoxin from Staphylococcus aureus and one of its substrates, oxidized pI258 arsenate reductase (ArsC) from S. aureus.

ArsC catalyses the reduction of arsenate to arsenite. Three redox active cysteine residues (Cys10, Cys82 and Cys89) are involved.
