INTRODUCTION: Neonatal respiratory disorders are a leading cause of perinatal mortality due to complications resulting from premature births and prenatal exposure to drugs of abuse, but optimal treatments for these symptoms are still unclear due to a variety of confounds and risk factors. Mouse models present an opportunity to study the underlying mechanisms and efficacy of potential treatments of these conditions with controlled variables. However, measuring respiration in newborn mice is difficult and commercial components are expensive and often require modification, creating a barrier and limiting our understanding of the short and long-term effects of birth complications on respiratory function...

Congenital dacryocystocele is a malformation of the nasolacrimal system. Most of the cases can be successfully treated with conservative treatment options such as sac massage. Congenital dacryocystoceles with concomitant intranasal cysts causing respiratory distress in the newborns are rarely published. In this case report we presented a 2-week-old newborn with bilateral congenital dacryocystoceles causing intermittent respiratory distress. We discuss the importance of nasal endoscopic treatment and multidisciplinary approach for these rare malformations in the light of the current literature...

PURPOSE: Although procalcitonin (PCT) level is useful for the diagnosis of neonatal sepsis, PCT reliability is inconsistent because of the varied conditions encountered in neonatal intensive care units. This study aimed to investigate PCT levels and factors influencing increased PCT levelin newborns without bacterial infection during the first week of life. METHODS: In newborns hospitalized between March 2013 and October 2015, PCT levels were measured on the first, third, and seventh days after birth...

Neutrophil migration and respiratory burst is the prerequisite for efficient first line defense against invading microorganisms. However, migration and respiratory burst can be compromised in adults and especially in newborn infants, where sustained neutrophil accumulation, uncontrolled burst and reduced scavenging of ROS might cause inadvertent tissue damage due to uncontrolled inflammation. The aim of this study was to investigate the modulatory effect of the chemoattractants formyl-methionyl-leucyl-phenylalanine (fMLP) and IL-8 on respiratory burst in neutrophils from term newborn infants and adults...

BACKGROUND: Pompe disease (PD) is the first lysosomal storage disorder to be added to the Recommended Uniform Screening Panel for newborn screening. This condition has a broad phenotypic spectrum, ranging from an infantile form (IOPD), with severe morbidity and mortality in infancy, to a late-onset form (LOPD) with variable onset and progressive weakness and respiratory failure. Because the prognosis and treatment options are different for IOPD and LOPD, it is important to accurately determine an individual's phenotype...

Courtney Denise Townsel, Sawyer F Emmer, Winston A Campbell, Naveed Hussain
For the past century, researchers have underscored the "disadvantage" observed in respiratory morbidity and mortality of male newborns. In this contemporary review, we examine gender differences in preterm infant respiratory morbidity and mortality specifically appraising differences in the very low birth weight (VLBW) population as well as the late preterm (LPT) population. In the era of postnatal surfactant and antenatal corticosteroids, the gender gap in neonatal outcomes has not narrowed. Structural, physiologic, and hormonal sex differences may be at the root of this disparity...

BACKGROUND: Newborn screening for mucopolysaccharidosis type I (MPS I) shows promise to improve outcomes by facilitating early diagnosis and treatment. However, diagnostic tests for MPS I are of limited value in predicting whether a child will develop severe central nervous system disease associated with Hurler syndrome, or minimal or no central nervous system involvement associated with the attenuated phenotypes (Hurler-Scheie and Scheie syndromes). Given that the optimal treatment differs between Hurler syndrome and the attenuated MPS I phenotypes, the absence of a reliable prognostic biomarker complicates clinical decision making for infants diagnosed through newborn screening...

This case report describes a rare phenotype of very severe spinal muscular atrophy (SMA) in a newborn who presented with reduced fetal movements in utero and significant respiratory distress at birth. The patient was homozygously deleted for exon 7 and exon 8 of the survival motor neuron gene 1. Very severe SMA should be considered in the differential diagnosis of respiratory distress at birth, and more research should be dedicated to investigate the genetic determinants of its widely variable phenotypes.

BACKGROUND: Dexmedetomidine is an alpha-2 (α2 ) adrenoceptor and imidazoline 1 (I1 ) receptor agonist that provides sedation without loss of respiratory drive. AIMS: The aim of this study was to elucidate the involvement of α2 -adrenoceptor and I1 receptor in the cardiorespiratory changes induced by dexmedetomidine in spontaneously breathing newborn rats. METHODS: An abdominal catheter to administer drugs and three subcutaneous electrodes to record electrocardiographic data were inserted into 2- to 5-day-old Wistar rats under isoflurane anesthesia...

Severe gastrointestinal bleeding in newborn period is a serious but uncommon phenomenon that has a broad differential diagnosis. Primary duodenal ulcers are rare in children but stress induced ulceration in stomach occurs more often in neonatal period due to birth asphyxia, prolonged labour, cesarean deliveries, instrumentations, respiratory distress syndrome and sepsis. These present as acute onset of gastrointestinal bleeding commonly as altered gastric aspirate, hematemesis or malena. We report a case of a neonate with stress induced gastric bleeding following birth asphyxia who presented with massive gastrointestinal bleed manifesting as hematemesis and massive rectal bleeding...

REVIEW
Martin Mueller, Boris W Kramer
Preterm birth is the leading cause of death in newborns and children. Despite advances in perinatology, immature infants continue to face serious risks such chronic respiratory impairment from bronchopulmonary dysplasia (BPD). Current treatment options are insufficient and novel approaches are desperately needed. In recent years stem cells have emerged as potential candidates to treat BPD with mesenchymal stem/stromal cells (MSCs) being particularly promising. MSCs originate from several stem cell niches including bone marrow, skin, or adipose, umbilical cord, and placental tissues...

BACKGROUND: Exposure to second-hand tobacco smoke (SHS) is one of the prime risk factors for chronic lung disease development. Smoking during pregnancy may lead to birth defects in the newborn that include pulmonary dysfunction, increased susceptibility to opportunistic pathogens, or initiation of childhood respiratory manifestations such as bronchopulmonary dysplasia (BPD). Moreover, exposure to SHS in early childhood can have negative impact on lung health, although the exact mechanisms are unclear...

OBJECTIVE: An unintended consequence of cystic fibrosis (CF) newborn screening (NBS) is the identification of infants with a positive NBS test but inconclusive diagnostic testing. These infants are classified as CF transmembrane conductance regulator-related metabolic syndrome (CRMS) in the US and CF screen positive, inconclusive diagnosis (CFSPID) in other countries. Diagnostic and management decisions of these infants are challenges for CF healthcare professionals and stressful situations for families...

Human metapneumovirus (hMPV), formerly classified in Paramyxoviridae family is now moved into Pneumoviridae, which was described as a novel family. It causes upper and lower respiratory tract infections (LRTIs) usually in children younger than five years old. The recent epidemiological studies indicated that hMPV is the second most frequently detected virus in LRTIs of young children, following the respiratory syncytial virus (RSV). Bronchiolitis obliterans (BO) is a chronic obstructive lung disease characterized by fibrosis of the distal respiratory airways...

In recent years there have been Pertussis outbreaks not seen in the last 50 years affecting adults, adolescents and children and causing deaths in young unvaccinated infants. In Chile an outbreak of Pertussis started in year 2011, leaving 16 infants less than 3 months dead during this year, twice the number seen in a non epidemic year. These children were infected before receiving the programmatic vaccines indicated at 2, 4 and 6 months of age, usually from close contacts, especially their mothers. Pertussis control has not been possible for several reasons, such as limited immunity duration of available vaccines and their poor impact on nasopharyngeal carriage, situation that keeps the agent's circulation and transmission, condition often asymptomatic or unrecognized...
