INTRODUCTION:  Choanal atresia is a rare abnormality. As neonates depend on transnasal respiration, bilateral choanal atresia causes an acute emergency. Transnasal endoscopic resection of congenital choanal atresia is a well-established therapy. However, the surgical technique has not yet been standardized. METHODS:  A retrospective chart review was performed with a follow-up examination between 9 to 87 months after surgery. 11 patients (7 with unilateral atresia, 4 with bilateral atresia) were included...

The neural cells and factors determining normal vascular growth are not well defined even though vision-threatening neovessel growth, a major cause of blindness in retinopathy of prematurity (ROP) (and diabetic retinopathy), is driven by delayed normal vascular growth. We here examined whether hyperglycemia and low adiponectin (APN) levels delayed normal retinal vascularization, driven primarily by dysregulated photoreceptor metabolism. In premature infants, low APN levels correlated with hyperglycemia and delayed retinal vascular formation...

BackgroundIn preterm infants, the time from initiation to full oral feeding can take weeks, which represents a very worrisome problem in neonatal medicine. Although current knowledge suggests that oral feeding should be introduced early, this is often delayed due to the need for prolonged nasal continuous positive airway pressure (nCPAP). Indeed, most caregivers fear that nCPAP could disrupt sucking-swallowing-breathing coordination and induce tracheal aspiration. The goal of the present study was to assess the impact of nCPAP delivered by the Infant Flow System on the physiology of sucking-swallowing-breathing coordination during bottle-feeding in preterm lambs over 24 h...

BACKGROUND: Perinatal hypoxia is one of the leading causes of perinatal mortality in developing countries. Both apgar score and arterial blood pH predict the neonatal mortality in asphyxia. Apgar score alone does not predict neurologic outcome and as it is influenced by various factors. This study was conducted to evaluate the utility and sensitivity of urinary uric acid to creatinine ratio (UA/Cr ratio) in asphyxia diagnosis, compared to invasive Arterial Blood Gas (ABG) analysis. AIM: To assess the urinary uric acid/creatinine ratio as an additional marker for perinatal asphyxia compared with ABG analysis in apgar score monitoring...

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...

AIM: Current clinical and laboratory diagnostics for neonatal infection are inadequate. An infant's systemic inflammatory response may be identified earlier than clinical suspicion by a computerized algorithm (RALIS) incorporating multiple vital signs (VS). We tested the ability of RALIS to detect late onset infection (LOI) earlier than clinically suspected. METHODS: We conducted a retrospective review of infants enrolled in a birth cohort study at Prentice Women's Hospital...

Use of high-flow oxygen via nasal cannula (HFO2-NC) is increasingly common in intensive care unit (ICU) settings. Despite the critical interface between respiration and swallowing, and the high acuity of patients in ICUs, the impact of HFO2-NC on feeding and swallowing is unknown. The present prospective, single-center, cohort study investigated the impact of HFO2-NC use on oral alimentation in neonatal and adult ICU patients. Oral alimentation status was evaluated in 100 consecutive ICU inpatients (50 neonatal and 50 adult) requiring HFO2-NC...

Stabilization of respiration and oxygenation continues to be one of the main challenges in clinical care of the neonate. Despite aggressive respiratory support including mechanical ventilation, continuous positive airway pressure, oxygen and caffeine therapy to reduce apnea and accompanying intermittent hypoxemia, the incidence of intermittent hypoxemia events continues to increase during the first few months of life. Even with improvements in clinical care, standards for oxygen saturation targeting and modes of respiratory support have yet to be identified in this vulnerable infant cohort...

BACKGROUND: Systemic glucocorticoids reduce the incidence of bronchopulmonary dysplasia among extremely preterm infants, but they may compromise brain development. The effects of inhaled glucocorticoids on outcomes in these infants are unclear. METHODS: We randomly assigned 863 infants (gestational age, 23 weeks 0 days to 27 weeks 6 days) to early (within 24 hours after birth) inhaled budesonide or placebo until they no longer required oxygen and positive-pressure support or until they reached a postmenstrual age of 32 weeks 0 days...

INTRODUCTION: Continuous improvements in perinatal care have allowed the survival of increasingly more prematurely born infants. The establishment of respiration in an extremely immature yet still developing lung results in chronic lung injury with significant mortality and morbidity. We experimentally evaluated a novel medical strategy to prevent hyperoxia-induced lung injury by prenatal rosiglitazone. MATERIALS AND METHODS: Pregnant rabbits were injected with saline or rosiglitazone (3 mg/kg) 48 and 24 h prior to preterm delivery at 28 days of gestation (term = 31 days)...

Surfactant replacement therapy (SRT) involves instillation of a liquid-surfactant mixture directly into the lung airway tree. It is widely successful for treating surfactant deficiency in premature neonates who develop neonatal respiratory distress syndrome (NRDS). However, when applied to adults with acute respiratory distress syndrome (ARDS), early successes were followed by failures. This unexpected and puzzling situation is a vexing issue in the pulmonary community. A pressing question is whether the instilled surfactant mixture actually reaches the adult alveoli/acinus in therapeutic amounts...
