Pulmonary capillary hemangiomatosis is a rare entity characterized by the proliferation of capillaries into alveolar walls, interlobular septa, pleura and pulmonary interstitium, without malignant characteristics, with almost constant association with pulmonary hypertension. Until now two cases of congenital presentation have been reported in the literature. This is the third case in a newborn; he has not followed the usual pattern associated with pulmonary hypertension as occurs in most patients with this pathology; the highest incidence is among 20-40 years old...

Severe Persistent pulmonary hypertension of the newborn (PPHN) can be effectively treated with a PDE3 inhibitor as first-line treatment during neonatal transport when iNO is not readily available. Starting iNO as soon as possible is strongly advised because of the complementary actions of both therapeutics.

BACKGROUND: Nitric oxide (NO) is a major endogenous regulator of vascular tone. Inhaled nitric oxide (iNO) gas has been investigated as treatment for persistent pulmonary hypertension of the newborn. OBJECTIVES: To determine whether treatment of hypoxaemic term and near-term newborn infants with iNO improves oxygenation and reduces rate of death and use of extracorporeal membrane oxygenation (ECMO), or affects long-term neurodevelopmental outcomes. SEARCH METHODS: We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 1), MEDLINE via PubMed (1966 to January 2016), Embase (1980 to January 2016) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to January 2016)...

Pulmonary hypertension (PH) is a complex disease comprising a pathologic remodeling and thickening of the pulmonary vessels causing an after load on the right heart ventricle that can result in ventricular failure. Triggered by oxidative stress, episodes of hypoxia, and other undetermined causes, PH is associated with poor outcomes and a high rate of morbidity. In the neonate, this disease has a similar etiology but is further complicated by the transition to breathing after birth, which requires a reduction in vascular resistance...

The final therapy of 'end-stage heart failure' is orthotopic heart, lung or heart-lung transplantation. However, these options are not available for many patients worldwide. Therefore, novel therapeutical strategies are needed. Based on pathophysiological insights regarding (1) the long-term impact of an obstructive pulmonary outflow tract in neonates with congenitally corrected transposition of the great arteries, (2) the importance of a restrictive versus a non-restrictive atrial septum in neonates born with a borderline left ventricle and (3) the significance of both, a patent foramen ovale and/or open ductus arteriosus for survival of newborns with persistent pulmonary hypertension, the current review introduces some therapeutical strategies that may be applicable to selected patients with heart failure...

This review summarizes our current knowledge on lung vasculogenesis and angiogenesis during normal lung development and the regulation of fetal and postnatal pulmonary vascular tone. In comparison to that of the adult, the pulmonary circulation of the fetus and newborn displays many unique characteristics. Moreover, altered development of pulmonary vasculature plays a more prominent role in compromised pulmonary vasoreactivity than in the adult. Clinically, a better understanding of the developmental changes in pulmonary vasculature and vasomotor tone and the mechanisms that are disrupted in disease states can lead to the development of new therapies for lung diseases characterized by impaired alveolar structure and pulmonary hypertension...

Bronchopulmonary dysplasia (BPD) is a frequent complication occurring in extremely preterm infants. Despite recent advances in newborn medicine, the incidence of BPD does not appear to have changed markedly, and specific treatments and prevention strategies are still lacking. Nutrition plays an important role in normal lung development and maturation. Malnutrition may delay somatic growth and new alveoli development, thus aggravating pulmonary injury involved in the pathogenesis of BPD. However, few nutrients have been investigated for their potential to mitigate the pathogenesis of BPD...

We sought to clarify the survival and neurodevelopmental outcomes of very low birth weight infants (VLBWIs) and to identify risk factors for death or neurodevelopmental impairment (NDI) in VLBWIs at our hospital. The total study population was 217 infants born in 2005-2012 weighing 1,500 g. We compared their outcomes with those from previous reports analyzed the causes of death. Risk factors for death after discharge or NDI were evaluated by a multivariate logistic regression analysis. The incidences of death or NDI reported revealed in this study and the database of Neonatal Research Network of Japan were 25...

: Noradrenaline (NA) is beneficial in the treatment of term newborns with cardiovascular compromise due to sepsis or pulmonary hypertension, but experiences with NA in preterm infants are limited. The aim of this study is to describe the efficacy and safety of NA in preterm infants. Patient records of preterm infants ≤32 weeks' gestation admitted to two hospitals between 2004 and 2015 and who received NA were reviewed for perinatal morbidities and mortality. Clinical details were collected at the time of NA use, and response on blood pressure, perfusion and oxygenation was documented as well as possible side effects...

BACKGROUND: Mesenchymal stem cells (MSC) improve alveolar and vascular structures in experimental models of bronchopulmonary dysplasia (BPD). Female MSC secrete more anti-inflammatory and pro-angiogenic factors as compared to male MSC. Whether the therapeutic efficacy of MSC in attenuating lung injury in an experimental model of BPD is influenced by the sex of the donor MSC or recipient is unknown. Here we tested the hypothesis that female MSC would have greater lung regenerative properties than male MSC in experimental BPD and this benefit would be more evident in males...

OBJECTIVES: Inhaled nitric oxide (iNO) is effective in conjunction with tracheal intubation (TI) and mechanical ventilation (MV) for treating arterial pulmonary hypertension and hypoxemic respiratory failure (HRF) in near-term and term newborns. Non-invasive respiratory support with nasal continuous positive airway pressure (CPAP) is increasingly used to avoid morbidity associated with TI and MV, yet the effectiveness of iNO delivery via nasal CPAP remains unknown. To evaluate the effectiveness of iNO delivered via the bubble nasal CPAP system in term and preterm newborns with HRF...

BACKGROUND: There have been few reports on the outcome of extracorporeal membrane oxygenation (ECMO) in newborn Japanese infants. METHODS: A review was carried out of 61 neonates with ECMO between January 1995 and December 2015 at a single center. ECMO was used in neonates with oxygenation index >20 after conventional treatment. Background factors, such as etiology, vascular access mode (veno-venous [VV] or veno-arterial [VA]), number of days with ECMO, and early ECMO (within 24 h after birth), were analyzed in relation to outcome with respect to survival to hospital discharge (SHD)...
