Expiratory braking defines the breathing patterns of asphyxiated neonates during therapeutic hypothermia.

Introduction: Although neonatal breathing patterns vary after perinatal asphyxia, whether they change during therapeutic hypothermia (TH) remains unclear. We characterized breathing patterns in infants during TH for hypoxic-ischemic encephalopathy (HIE) and normothermia after rewarming.

Methods: In seventeen spontaneously breathing infants receiving TH for HIE and in three who did not receive TH, we analyzed respiratory flow and esophageal pressure tracings for respiratory timing variables, pulmonary mechanics and respiratory effort.

Analysis of Knowledge, Attitudes and Behaviours of Health Care Workers towards Vaccine-Preventable Diseases and Recommended Vaccinations: An Observational Study in a Teaching Hospital.

Background: Recommended vaccinations are the cheapest and most effective measure to reduce the risk of transmission and related complications, especially in high-risk healthcare settings. This study aimed to evaluate the knowledge, attitudes and behaviours of HCWs in relation to national recommendations. Methods: A transversal study was conducted through administration of a questionnaire by personal interview.

The starting rate for high-flow nasal cannula oxygen therapy in infants with bronchiolitis: Is clinical judgment enough?

Objectives: To determine whether in infants with bronchiolitis admitted to a pediatric intensive care unit (PICU) the starting rate for high-flow nasal cannula (HFNC) therapy set by the attending physicians upon clinical judgment meets patients' peak inspiratory flow (PIF) demands and how it influences respiratory mechanics and breathing effort.

Methodology: We simultaneously obtained respiratory flow and esophageal pressure data from 31 young infants with moderate-to-severe bronchiolitis before and after setting the HFNC rate at 1 L/kg/min (HFNC-1), 2 L/kg/min (HFNC-2) or upon clinical judgment and compared data for PIF, respiratory mechanics, and breathing effort.

Results: Before HFNC oxygen therapy started, 16 (65%) infants had a PIF less than 1 L/kg/min (normal-PIF) and 15 (45%) had a PIF more than or equal to 1 L/kg/min (high-PIF).

Lipid Peroxidation and Antioxidant Consumption as Early Markers of Neurosurgery-Related Brain Injury in Children.

Background And Aims: Lipid peroxidation represents a marker of secondary brain injury both in traumatic and in non-traumatic conditions-as in major neurosurgical procedures-eventually leading to brain edema amplification and further brain damage. Malondialdehyde (MDA), a lipid peroxidation marker, and ascorbate, a marker of antioxidant status, can represent early indicators of this process within the cerebrospinal fluid (CSF). We hypothesized that changes in cerebral lipid peroxidation can be measured ex vivo following neurosurgery in children.

Three-dimensional airways volumetric analysis before and after fast and early mandibular osteodistraction.

Purpose: Newborns with Pierre Robin sequence (PRS) and syndromic micrognathia show microgenia and glossoptosis, which cause reduction of the airway and breathing difficulty from birth. Our goal is to analyze quantitative and qualitative volumetric changes before and after fast and early mandibular osteodistraction (FEMOD) and to compare radiological data.

Methods: The sample was composed of 4 patients, who satisfied inclusion criteria for completeness of data.

The role of vancomycin in addition with colistin and meropenem against colistin-sensitive multidrug resistant Acinetobacter baumannii causing severe infections in a Paediatric Intensive Care Unit.

Background: Acinetobacter baumannii has been associated with high morbidity and mortality rates, even in pediatric patients. Therapeutic options are limited, especially when the strain is multidrug resistant.

Methods: Clinical and microbiological analyses of 4 cases of systemic infections caused by multi drug resistant A.

Proven Epstein-Barr encephalitis with negative EBV-DNA load in cerebrospinal fluid after allogeneic hematopoietic stem cell transplantation in a child with acute lymphoblastic leukemia.

We report a case of EBV encephalitis in a seven-yr-old child with Ph+ ALL. Two months after an allogeneic HSCT from his HLA mismatched mother, the patient showed an altered sensorium, generalized seizures, and a left hemiparesis. Brain MRI demonstrated multiple lesions highly suggestive for viral encephalitis.

Outcomes after tongue-lip adhesion or mandibular distraction osteogenesis in infants with Pierre Robin sequence and severe airway obstruction.

The objective was to review and compare outcomes after tongue-lip adhesion (TLA) and mandibular distraction osteogenesis (MDO) in infants with severe breathing difficulties related to Pierre Robin sequence (PRS). A single-centre retrospective (2002-2012) study was carried out; 18 infants with severe breathing difficulties related to PRS resistant to conservative treatment, who underwent TLA or MDO to correct airway obstruction, were enrolled. The primary outcome measures were successful weaning from respiratory support and resumption of full oral feeding.

Beneficial effects of levosimendan in infants with sepsis-associated cardiac dysfunction: report of 2 cases.

Although international guidelines for hemodynamic support of pediatric septic shock suggest considering the potent calcium sensitizer inodilator levosimendan as a second-line inotropic agent to treat cold hypodynamic shock resistant to catecholamines, clinical experience in septic infants is lacking. We report the beneficial effects of levosimendan infusion in 2 infants (39 and 64 days old) with low cardiac output septic shock (ejection fraction, 29% and 33%; fractional shortening, 10% and 16% respectively) refractory to volume replacement and to the catecholamines dopamine and dobutamine. Levosimendan infusion (0.

Current strategies for treating infants with severe bronchopulmonary dysplasia.

Advances in neonatal intensive care have markedly improved survival rates for infants born at a very early lung development stage (<26 weeks gestation). In these premature infants, even low inspired oxygen concentrations and gentle ventilatory methods may disrupt distal lung growth, a condition described as "new" bronchopulmonary dysplasia (BPD). BPD usually develops into a mild form, with only few infants requiring ventilator support and oxygen supplementation at 36 weeks post-conception.

Mandibular distraction osteogenesis for neonates with Pierre Robin sequence and airway obstruction.

Neonates with Pierre Robin Sequence (PRS) usually present with varying degrees of upper airway obstruction and difficulty feeding. Early treatment is important for such children in order to prevent impaired cognitive development resulting from hypoxemic episodes. Various procedures aimed at widening the pharyngeal space have been proposed, including prone position, tongue-lip adhesion, mandibular traction, non-invasive ventilation and palatal plates.

Gut microbial translocation in critically ill children and effects of supplementation with pre- and pro biotics.

Bacterial translocation as a direct cause of sepsis is an attractive hypothesis that presupposes that in specific situations bacteria cross the intestinal barrier, enter the systemic circulation, and cause a systemic inflammatory response syndrome. Critically ill children are at increased risk for bacterial translocation, particularly in the early postnatal age. Predisposing factors include intestinal obstruction, obstructive jaundice, intra-abdominal hypertension, intestinal ischemia/reperfusion injury and secondary ileus, and immaturity of the intestinal barrier per se.

Sevoflurane inhalation for severe bronchial obstruction in infants with bronchiolitis.

Bronchiolitis is a lower respiratory tract viral infection which may result in severe bronchial obstruction and respiratory failure despite treatment with beta-adrenergic agonists and glucocorticoids. Here we describe two otherwise healthy infants with severe bronchiolitis whose clinical course was complicated by marked bronchial obstruction and respiratory acidosis refractory to conventional medications (β-stimulants, anticholinergics and corticosteroids) and non-invasive positive pressure ventilation. Sevoflurane inhalation allowed both infants to attain a sustained, clinical improvement in ventilation and one patient to avoid mechanical ventilation.

What's new in the treatment of neonatal shock.

Shock is a clinical disorder that challenges caregivers in the neonatal intensive care unit. The predominant cause of shock in neonates is sepsis. This article provides an overview of the current treatment of septic shock with particular emphasis on newer vasoactive drugs (milrinone, levosimendan and vasopressin) to support cardiovascular dysfunction.

[Ventilatory care].

Mechanical ventilation is considered a supportive, nontherapeutic technology used to perform the work of breathing for patients who are unable to do so on their own. In neonatology, mechanical ventilation is often used for premature neonates who are unable to sustain ventilation because of reduced functional residual capacity due to surfactant deficiency. Mechanical ventilation is thus an attempt to mimic the respiratory system's physiological function of gas exchange until the respiratory system reaches maturation.

Blood loss and short-term outcome of infants undergoing brain tumour removal.

Objective: To evaluate perioperative management, early outcomes and hemocoagulative disorders in infants up to 1 year old, undergoing neurosurgery for brain tumors removal.

Design: Retrospective evaluation of prospectively collected data regarding all infants aged <1 year admitted to PICU from 1994 to 2004, following intracranial mass removal.

Interventions: none.

Massive blood transfusion in choroid plexus tumor surgery: 10-years' experience.

Study Objective: To describe our 10 years of experience with childhood choroid plexus tumors (CPTs).

Design: Retrospective chart analysis.

Setting: Operating room and pediatric intensive care unit (PICU) of a university hospital.

Oxidation of intravenous lipid in infants and children with systemic inflammatory response syndrome and sepsis.

During sepsis in adults, fat becomes a preferred fuel; however, oxidation may be impaired relative to the circulating fatty acid levels. Little is known about the ability of infants and children to oxidize lipids during systemic inflammation (SIRS) and sepsis. The aim of this study was to examine the oxidation of exogenous lipid in these patients.

Sharing features of uncommon respiratory syncytial virus complications in infants.

We describe 4 nonconsecutive cases of infants admitted to Catholic University pediatric intensive care unit (PICU) because of complicated respiratory syncytial virus (RSV) infection during winter RSV outbreaks from the year 2000 to the year 2003. A hyponatremic epileptic status (as in the first case) has been reported by several authors as a rare RSV complication, potentially leading to death. The second infant developed a serious pulmonary edema after a subglottic obstruction (croup) associated with RSV infection.

Lung injury from "liquid ecstasy": a role for coagulation activation?

We describe our second clinical observation of pulmonary injury after a "liquid ecstasy" ingestion/inhalation by a 3-year-old girl. Apart from the deep coma state, a markedly asymmetric pulmonary compromise was recorded. A transient coagulation activation was detected, possibly triggered off by the toxic effect on the lung alveolar-capillary membrane.
