Detection of Hepatitis B Virus DNA in the Liver of Children with Chronic Hepatitis B by In Situ Hybridization and Its Relation to Other Viral Markers
1992
The aim of the study was to detect hepatitis B virus (HBV) DNA by in situ hybridization (ISH) with a 35S-labeled radioactive probe in frozen liver biopsy tissue sections of 63 hepatitis B virus surface antigen (HBsAg)-positive children. The results were compared to other markers of viral replication. HBV DNA was detected in 48 children. Of the 15 negative cases, four had hepatitis B envelope antigen (HBeAg), 10 anti-HBe, and one neither HBeAg nor anti-HBe. Free HBV DNA in serum and liver was positive in one patient. Forty of the positive children were HBeAg- and six anti-HBe-positive; two were negative for both. Of 45 36 had HBV DNA in serum. In 38 of 47 HBV DNA and in 31 of 42 HBcAg could …
Steatocrit test: Normal range and physiological variations in infants
1990
In order to define the normal values of steatocrit during the first 3 months of life and the normal correlation between fecal fat content and steatocrit values, 60 full-term healthy unweaned infants (30 bottle-fed, 15 breast-fed, and 15 mixed-fed) were studied. The steatocrit micromethod was performed in these babies at 7, 14, 21, 28, 45, and 90 days after birth. Steatorrhea often occurs during the first month and then decreases, as shown by the fall in the steatocrit curve from 7th to 28th day in our subjects; at 45 days, few babies have steatorrhea. The 90th percentile profile of steatocrit values shows a value of 25% at the first week of life and a value of 13% at the fourth week. After …
VATER/VACTERL association: clinical variability and expanding phenotype including laryngeal stenosis.
1992
Vertebral abnormalities and anorectal and tracheoesophageal defects are the main manifestations in the VATER/VACTERL association. Radial defects vary from radial aplasia to thumb duplication. Heart and renal defects are reported with lower frequency. Additional malformations, such as the laryngeal stenosis described in the present patient, may expand the phenotype of the association. The wide spectrum of congenital abnormalities confirms the high clinical variability of VATER/VACTERL association which seems to be due to a disruption of blastogenesis. © 1992 Wiley-Liss, Inc.
Probiotics Properties: A Focus on Pregnancy Outcomes.
2021
A healthy microbiome plays an important role in the prevention of illness and maintenance of overall health, including reproductive health. Although the therapeutic advantages of probiotics have been shown to run across multiple organ systems, their role in pregnancy is not well explored. The aim of this review is to highlight the potential advantages and adverse effects of probiotics in pregnancy. Data were collected from the literature over the past decade using PubMed, Medline, Google Scholar, Ovid, Scopus, and Science Direct. A total of 40 articles were utilized in this review. Collected data indicated that prenatal and post-natal supplementation with lactobacilli alone or lactobacilli …
The embryo-placental CD15-positive "vasculogenic zones" as a source of propranolol-sensitive pediatric vascular tumors.
2015
Abstract Objective Propranolol-induced involution is a unique biological feature of some pediatric vascular tumors, for instance infantile hemangioma (IH), cerebral cavernoma or chorioangioma. Currently, the cellular origin of these distinct tumors is unclear. In this study, we tested the hypothesis that propranolol-responsive vascular tumors are derived from common vessel-forming CD15 + progenitor cells which occur in early gestation. The aim of this study was to identify the tumor-relevant CD15 + progenitors at the early stages of embryo-placental development. Materials and methods Human embryo-placental units of 4–8 weeks gestation and pediatric vascular tumors were tested for expression…
Effects of Infant Formula With Human Milk Oligosaccharides on Growth and Morbidity: A Randomized Multicenter Trial
2017
Objectives:The aim of the study was to evaluate the effects of infant formula supplemented with 2 human milk oligosaccharides (HMOs) on infant growth, tolerance, and morbidity. Methods:Healthy infants, 0 to 14 days old, were randomized to an intact-protein, cow's milk-based infant formula (control, n=87) or the same formula with 1.0g/L 2fucosyllactose (2FL) and 0.5g/L lacto-N-neotetraose (LNnT) (test, n=88) from enrollment to 6 months; all infants received standard follow-up formula without HMOs from 6 to 12 months. Primary endpoint was weight gain through 4 months. Secondary endpoints included additional anthropometric measures, gastrointestinal tolerance, behavioral patterns, and morbidit…
AMPA receptor GluA2 subunit defects are a cause of neurodevelopmental disorders.
2019
AMPA receptors (AMPARs) are tetrameric ligand-gated channels made up of combinations of GluA1-4 subunits encoded by GRIA1-4 genes. GluA2 has an especially important role because, following post-transcriptional editing at the Q607 site, it renders heteromultimeric AMPARs Ca2+-impermeable, with a linear relationship between current and trans-membrane voltage. Here, we report heterozygous de novo GRIA2 mutations in 28 unrelated patients with intellectual disability (ID) and neurodevelopmental abnormalities including autism spectrum disorder (ASD), Rett syndrome-like features, and seizures or developmental epileptic encephalopathy (DEE). In functional expression studies, mutations lead to a dec…
El acogimiento de menores con necesidades especiales y su relación con el perfil de las familias acogedoras
2013
El acogimiento familiar en cualquiera de sus modalidades, es un recurso que pretende proteger a la infancia en situación de riesgo y/o desamparo y posibilitar un desarrollo integral y comunitario a la vez que reparador, todo ello dentro de un entorno de familia (familia extensa o familia ajena). El objetivo del presente estudio, ha sido encontrar relaciones entre el perfil de la familia acogedora en los acogimientos en familia ajena y los problemas del menor en el momento de inicio del acogimiento. Se analizaron si las características familiares, incluyendo el tipo de familia, sus motivaciones o la situación laboral, predisponen o facilitan a acoger menores con problemas físicos y/o psicoso…
Intrahepatic bile duct dilation and gallbladder hydrops due to a cystic duct stenosis in a 2-month-old boy.
2015
A 2-month-old boy presented with slight diffuse abdominal pain after an uncomplicated pregnancy and perinatal period. Height (62 cm) and weight (5.5 kg) were according to the age. Routine blood tests showed no abnormalities except for a minimal elevation of aspartate aminotransferase to 38 units/L (reference range 5–35 U/L). Primary abdominal ultrasound showed a dilation of the common bile duct and a gallbladder hydrops (figure 1). MR cholangiopancreatography (MRCP) was indicated to detect the cause for these incidental findings. Contrary to normal bile ducts in …
Analysis of nucleophosmin–anaplastic lymphoma kinase (NPM‐ALK)‐reactive CD8+ T cell responses in children with NPM‐ALK+ anaplastic large cell lymphoma
2016
Summary Cellular immune responses against the oncoantigen anaplastic lymphoma kinase (ALK) in patients with ALK-positive anaplastic large cell lymphoma (ALCL) have been detected using peptide-based approaches in individuals preselected for human leucocyte antigen (HLA)-A*02:01. In this study, we aimed to evaluate nucleophosmin (NPM)-ALK-specific CD8+ T cell responses in ALCL patients ensuring endogenous peptide processing of ALK antigens and avoiding HLA preselection. We also examined the HLA class I restriction of ALK-specific CD8+ T cells. Autologous dendritic cells (DCs) transfected with in-vitro-transcribed RNA (IVT-RNA) encoding NPM–ALK were used as antigen-presenting cells for T cell …
