This study aims to compare the cerebellar biochemical profiles in preterm (PT) infants evaluated at term equivalent age (TEA) and healthy full-term newborns using proton magnetic resonance spectroscopy ((1)H-MRS). We explore the associations between altered cerebellar metabolite profiles and brain injury topography, severity of injury, and prematurity-related clinical complications. We prospectively collected high quality (1)H-MRS in 59 premature infants born ≤32 weeks and 61 healthy full term controls. (1)H-MRS data were processed using LCModel software to calculate absolute metabolite concentration for N-acetyl-aspartate (NAA), choline (Cho) and creatine (Cr)...

BACKGROUND: Hypophosphatasia (HPP) is a rare genetic disorder characterized by rachitic bone manifestations and a low serum alkaline phosphatase (ALP) level. It is caused by mutations in the tissue non-specific alkaline phosphatase (TNSALP) gene, which encodes the tissue non-specific isozyme of ALP. HPP patients exhibit various presentations depending on their age at onset, such as infantile HPP combined with vitamin B6-responsive seizures. CASE PRESENTATION: A newborn with infantile HPP presented with tonic convulsions from day 5 after birth and received intravenous vitamin B6 (10mg/kg/day pyridoxal phosphate)...

Improving the management of neonatal diseases and prevention of chronic diseases in adulthood requires a better comprehension of the complex maturational processes associated with newborns development. Urine-based metabolomic studies play a promising role in the fields of pediatrics and neonatology, relying on simple and non-invasive collection procedures while integrating a variety of factors such as genotype, nutritional state, lifestyle and diseases. Here, we investigate the influence of age, weight, height and gender on the urine metabolome during the first 4 months of life...

In this chapter we describe the current Quebec NTBC Study protocol. Quebec's unique characteristics have influenced the development of the protocol, including a high prevalence of hepatorenal tyrosinemia (HT1), universal newborn screening for HT1, availability of treatment with nitisinone (NTBC) and special diet, a large territory, where HT1 treatment is coordinated by a small number of centers. Screened newborns are seen within 3 weeks of birth. Patients with liver dysfunction (prolonged prothrombin time and/or international normalized ratio (INR) provide sensitive, rapidly available indicators) are treated by NTBC and special diet...

BACKGROUND: Maternal inflammation during pregnancy increases the risk for offspring psychiatric disorders and other adverse long-term health outcomes. The influence of inflammation on the developing fetal brain is hypothesized as one potential mechanism but has not been examined in humans. METHODS: Participants were adult women (N = 86) who were recruited during early pregnancy and whose offspring were born after 34 weeks' gestation. A biological indicator of maternal inflammation (interleukin-6) that has been shown to influence fetal brain development in animal models was quantified serially in early, mid-, and late pregnancy...

Intestinal cystic duplications are rare congenital anomalies, with an estimated incidence of approximately 1:4500 autopsies. The etiopathogenesis is uncertain. These duplications are cystic, tubular or diverticular structures lined with gastrointestinal mucosa. They share a common smooth muscle wall with the gastrointestinal tract but usually their lumens do not communicate with each other. Gastric duplication cysts represent 7-9% of the gastrointestinal tract duplication. They can be diagnosed prenatally by fetal ultrasound; magnetic resonance imaging characterizes the cyst and excludes other malformations...

Calcaneus osteomyelitis is a rare infection in newborns. Invasive procedures, prematurity and low birth wight are some causative factors. The clinical signs may be mild. We report a neonate with calcaneous osteomyelitis which was secondary to a Guthrie test sample. She was admitted to hospital with swelling, redness and increased temperature on her heel. Superficial tissue ultrasound showed fluid collection with heavy content was observed on the posterior of the right foot. Puncture and drainage was performed and methicillin-susceptible Staphylococcus aureus was isolated from the drainage culture...

We retrospectively analyzed newborns with deafness gene mutations and summarized the relationship between genotype and phenotype to provide a basis for genetic counseling. We studied 582 subjects positive for deafness gene mutations that were treated in the otology outpatient department of Beijing Tongren Hospital, Capital Medical University, between April 2012 and April 2016. The subjects were divided into 3 categories: a diagnosed group (group A), which was further subdivided into subgroups A1 (homozygous and compound heterozygous GJB2 mutations) and A2 (homozygous and compound heterozygous SLC26A4 mutations); a drug-induced deafness group (group B, mitochondrial (Mt) gene mutations); and a mutation carrier group (group C), which was further subdivided into the subgroups C1 (GJB2 heterozygous mutations), C2 (SLC26A4 heterozygous mutations), C3 (GJB3 heterozygous mutations), and C4 (double gene mutations)...

OBJECTIVE: The precision and accuracy of a quantitative magnetic resonance (EchoMRI Infants) system in newborns were determined. METHODS: Canola oil and drinking water phantoms (increments of 10 g to 1.9 kg) were scanned four times. Instrument reproducibility was assessed from three scans (within 10 minutes) in 42 healthy term newborns (12-70 hours post birth). Instrument precision was determined from the coefficient of variation (CV) of repeated scans for total water, lean mass, and fat measures for newborns and the mean difference between weight and measurement for phantoms...

We report a case of intrapericardial teratoma, which is a rare primary cardiac tumor usually found in newborns and infants. Cardiac teratomas can cause respiratory failure, large accumulations of pericardial fluid and cardiac compression leading to death in the intrauterine or neonatal period. The case described is rare because it is of a 16-year-old asymptomatic girl with an intrapericardial tumor as an incidental echocardiographic finding. Cardiac magnetic resonance imaging showed a complex pericardial cyst...

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is the most common cause of severe neonatal thrombocytopenia and intracranial bleeding in term newborns. Intracranial hemorrhage (ICH) commonly results in death or severe, lasting neurologic disability. The timing of ICH is also important for management of the next affected pregnancy in cases of FNAIT. This manuscript reviews the advantages and disadvantages of the different radiologic methodologies to identify and characterize ICH. It discusses the limits of ultrasound and the advantages of magnetic resonance imaging allowing avoidance of the radiation associated with computed tomography (CT) scans...

Proptosis in the neonatal period is relatively infrequent and has diverse underlying etiologies. One of the more common causes appears to be orbital subperiosteal hematoma. Early detection, differentiation from other causes, and regular follow-up are essential as loss of vision can occur. We describe two cases of neonatal proptosis caused by orbital subperiosteal hematoma highlighting different diagnostic and management approaches, and provide a summary of previously reported cases. Spontaneous resolution occurs in most cases; however, emergent surgical evacuation is warranted in cases of optic nerve compression...

BACKGROUND Congenital chloride diarrhea (CCD) is a rare autosomal recessive disorder that is difficult to distinguish from fetal lower intestinal obstruction. A prenatal diagnosis will make a contribution to the prognosis of the newborn. CASE REPORT We report a rare case of congenital chloride diarrhea (CCD) prenatally suspected by ultrasound and MRI. The prenatal ultrasound revealed signs of intestinal dilatation suggesting lower intestinal obstruction. MRI findings also revealed intestinal dilatation that continued from the rectum...

BACKGROUND: Brain injury can be identified as early as day two of life in asphyxiated newborns treated with hypothermia, when using diffusion magnetic resonance imaging (MRI). However, it remains unclear whether these diffusion changes can predict future neurodevelopment. This study aimed to determine whether abnormal early diffusion changes in newborns treated with hypothermia are associated with adverse neurodevelopmental outcome at age two years. METHODS: Asphyxiated newborns treated with hypothermia were enrolled prospectively...

BACKGROUND: Developmental dysplasia of the hip (DDH) is one of the most common congenital defects in the newborn. When its severe form is not corrected, it is associated with long-term morbidity. Closed reduction with casting is the standard primary treatment and reduction is confirmed by magnetic resonance imaging (MRI). We reported our experience on the reliability of MRI in postreduction assessment of DDH. METHODS: All children who underwent closed reduction for Graf type IV DDH at our institution between September 2010 and June 2016 were retrospectively reviewed...
