Article Abstract

The activities of ATP-consuming and ATP-producing steps of the Embden-Meyerhof pathway, as well as other glycolytic enzymes (phosphoglucomutase and enolase) and glucose-6-phosphate dehydrogenase are lower in leucocytes from cord blood than in white cells from adults. These results are related to previous observations (reduced anaerobic glycolysis and nitroblue tetrazolium-test in leucocytes from newborn infants) and discussed in connection with the fact that newborn infants are more susceptible to infections than normal adults.

The main objective of this prospective, multicenter study (REVEAL-CP) was to test children with cerebral palsy-like signs and symptoms for raised 3--methyldopa (3-OMD) blood levels, a biomarker for aromatic L-amino acid decarboxylase deficiency (AADCd). A secondary objective was to characterize the molecular basis for the defective aromatic L-amino acid decarboxylase (AADC) gene product. Patients were identified in pediatric secondary and tertiary care hospitals through database searches and personal communication.

Objective: The aim of this study was to analyze if the healthcare organization of perinatal care and availability of referral neonatal intensive care units (NICU) impacted congenital diaphragmatic hernia (CDH) neonatal mortality in the period 2004-2020. This study analyzed the spatial distribution of neonatal deaths of live births with CDH in São Paulo State, Brazil, and its association with NICU beds' availability.

Methods: Population-based study of all live births in São Paulo State from mothers residing in the same State, from 2004 to 2020.

Objective: 3p deletion syndrome is a rare monosomal disease that encompasses deletions throughout the short arm of chromosome 3. It is often in the distal region (3p25-pter), but variations in breakpoints and a complex clinical manifestation exist, with congenital heart defects being considered rare. We present the first case of hypoplastic left heart syndrome and minor dysmorphic features associated with 3p- syndrome.

Objective: To analyze the effect of the thoracoabdominal rebalancing (TAR) method on respiratory biomechanics, respiratory discomfort, pain sensation, and physiological parameters in moderate preterm newborns, compared to a control group.

Methods: This randomized clinical trial was conducted in a neonatal intensive care unit. The evaluation included: Neonatal Infant Pain Scale, physiological parameters, Silverman-Andersen score, and biomechanics (thoracic cirtometry and Charpy angle).

Congenital toxoplasmosis in infants from chronically infected mothers: report of two cases.

Rev Paul Pediatr

January 2025

Universidade Federal de Goiás, Institute of Tropical Pathology and Public Health, Parasite-Host Relationship Studies Laboratory, Goiânia, GO, Brazil.

Objective: To describe two severe cases of congenital toxoplasmosis in infants born to chronically infected mothers who did not receive education or information on the prevention of gestational toxoplasmosis during prenatal care.

Case Description: The mothers had a previous serological diagnosis of toxoplasmosis conducted during prenatal care, with non-reactive (<10 IU/mL) IgM and reactive IgG (>10 IU/mL), and were considered "immune" to the infection. Both infants were born with sequelae of the congenital infection, including neurological and ocular alterations.
