As observed in other airborne viral infections such as influenza and SARS-CoV-1, healthcare workers are at high risk for infection when performing aerosol-generating medical procedures (AGMP). Additionally, the threats of a global shortage of standard personal protective equipment (PPE) prompted many healthcare workers to explore alternative protective enclosures, such as the “aerosol box” invented by a Taiwanese anesthetist. Our study includes the design process of a protective barrier enclosure and its subsequent clinical implementation in the management of critically ill adults and children infected with SARS-CoV-2. Methods and Results The barrier enclosure was designed for use in our tertiary care facility and named “SplashGuard CG” (CG for Care Givers). The device has been adapted using a multi- and interdisciplinary approach, with colla...

The defect may lead to an endogenous intoxication if toxic metabolites accumulate upstream, or energy failure downstream, in case of energy production pathway impairment. Clinical presentations mostly depend on defective enzyme residual activity and explain why most of severe cases are seen in childhood. Partial deficit may result in acute onset in adults, specially in fasting conditions with catabolic stress. This review relates inborn errors of metabolism that may be responsible for life threatening conditions in adulthood and require a particular management.

Case 1. A girl, aged 11 months, was found in her apartment 15 minutes after the start of accidental fire. She was in a stage I coma with cyanosis and covered with soot. She was placed on oxygen and given hydroxocobalamin. Aggravation of respiratory problems led to mechanical ventilation. Tracheobronchoscopy showed deposits of soots with moderate burnt lesions. Intubation was discontinued 12 hours later, but the child remained oxygen-dependent, with persistent tracheobronchitis, despite steroid therapy for 2 weeks. Case 2. Another girl, aged 4 1/2 years, was found in the same room as the preceding patient. She was also covered with soot, and in a coma (Glascow score = 11). She was intubated, placed on mechanical ventilation, and given hydroxocobalamin. Tracheobronchoscopy revealed similar changes to those seen in the preceding patient. Despite repeated tracheobronchial washings and steroid therapy, respiratory problems persisted with thoracic distension and pneumothorax. Mechanical ventilation was discontinued 16 days later but at 5 1/2 years, this child still has dyspnea and has developed bronchiectasis. Bronchopulmonary changes can be a severe complication of smoke inhalation during fires, and require early mechanical ventilation and repeated tracheobronchoscopy.

In each of these situations, careful medical history is of major importance searching for previous clinical manifestations such as episodes of coma, ataxia or vomiting, anorexia, failure to thrive, developmental delay, all very suggestive of metabolic disorder. The association of neurological symptoms and abnormal hepatic tests is also of great value and must not lead to the diagnosis of Reye's syndrome without considering a metabolic defect of fatty acid oxidation, urea cycle, respiratory chain, or Wilson's disease. When looking for an etiological origin, it is mandatory to collect all the biological information at the same time, also knowing that metabolic abnormalities may be mild and transitory, and that many of them are non specific (metabolic acidosis, hyperlactacidemia, hyperammonemia, hepatic tests disturbances) being encountered in collapsus, shock and multiple organ failure syndrome.

After several days of post-chemotherapy aplasia a peritoneal, cutaneous (blackish necrosis), then pleuropulmonary involvement occurred. Fiberendoscopy showed an esophageal necrosis responsible for a pleural fistula. The child died after a few weeks, despite antifungal treatment. Post mortem examination found disseminated abscesses related to mucormycosis. The 41 pediatric cases in the world-wide literature are recorded.

Renal failure occurs due to the excessive production and precipitation of oxalate in the kidney. Combined liver-renal transplantation is the correct treatment for this condition when end-stage renal failure occurs as with renal transplantation alone the risk of recurrence of the same pathology in the transplanted kidney would be high. We report the case of a 4 year-old child with HPI suffering from terminal renal failure in whom a hepato-renal transplantation was performed: six months later, creatinine clearance was 62 ml/min/1.73 m2 and liver function tests were normal.

It involves bones, arteries, eyes, heart, nerves, etc. The management of oxalosis starts with prevention of nephrocalcinosis and renal failure by diluting urine and by inhibiting oxalate crystal formation either by increasing the urinary citrate or the urinary pyrophosphate. At endstage renal disease (ESRD) there is no dialysis modality for avoiding the progression of oxalosis. Combined liver/kidney transplantation (LKT) represents the most effective approach. The European PHI transplant registry recently reported 64 LKT with a five-year patient survival of 80% and progressive healing of oxalosis. Four children who received LKT in our unit are reported, all of whom are alive with a follow-up of three months to five years. Bone disease completely healed in one case after three years, but retinal deposits persisted despite improvement of visual acuity. A special perio...

Electronic searches of PubMed, EMBASE, Web of Science, Cochrane, and Scopus were conducted. References were reviewed for relevance and features included in the following section. Not applicable. PICU patients with evidence of acute lung injury, acute hypoxemic respiratory failure, and acute respiratory distress syndrome. Not applicable. The comorbidities associated with outcome in pediatric acute respiratory distress syndrome can be divided into 1) patient-specific factors and 2) factors inherent to the disease process. The primary comorbidity associated with poor outcome is preexisting congenital or acquired immunodeficiency. Severity of disease is often described by factors identifiable at admission to the ICU. Many measures that are predictive are influenced by the underlying disease process itself, but may also be influenced by nutritional status, chronic comorbidities, or underlying genetic predisposition. Of the measures available at the bedside, both PaO2/FIO2 ratio and oxygenation index are fairly consistent and robust predictors of disease severity and outcomes. Multiple organ system dysfunction is the single most important independent clinical risk factor for mortality in children at the onset of acute respiratory distress syndrome. The assessment of oxygenation and ventilation indices simultaneously with genetic and biomarker measurements holds the most promise for improved risk stratification for pediatric acute respiratory distress syndrome patients in the very near future. The next phases of pediatric acute respiratory distress syndrome pathophysiology and outcomes research will be enhanced if 1) age group differences are examined, 2) standardized datasets with adequately explicit definitions are used, 3) data are obtained at standardized times after pediatric acute respiratory distress syndrome onset, and 4) nonpulmonary organ failure scores are created and implemented.
