Red cell distribution width (RDW) as a biomarker for respiratory failure in a pediatric ICU
Abstract Background The red cell distribution width (RDW) is a widely available, inexpensive, and highly reproducible test that reflects the range of the red cell sizes. Any process that releases reticulocytes in the circulation will result in an increase in RDW. Elevated RDW values are linked to worsened pulmonary function in the adult population. We performed a retrospective cohort study to describe the association between RDW and respiratory failure in critically ill children in a in a pediatric intensive care unit (PICU) in a tertiary university hospital. Subjects All patients admitted between January 2009 and June 2015 were considered eligible for inclusion. Methods Retrospective cohort study. Results In total, 960 patients were included in the cohort analysis. Of those patients, 149 (15.5%) had elevated RDW values. RDW on admission was associated with lower 28 day ventilator-free days. The highest quintile of RDW was associated with the need for mechanical ventilation, even when correcting for anaemia, age and Pediatric Risk of Mortality (PRISM) scores. In the subgroup of ventilated patients, RDW was associated with nadir PaO2/FiO2(P/F) ratios. Conclusion The RDW value on admission of our PICU patients is associated with a greater need for invasive mechanical ventilation, lower 28 day ventilator-free days and lower nadir P/F ratios in the patients with highest RDW values on admission. RDW may be a valuable, cheap and universally available, prognostic parameter for respiratory dysfunction in the PICU
Diagnosis and therapy of adrenal insufficiency in pediatric septic shock:from theory to practice
A Spinal Arteriovenous Fistula in a 3-Year Old Boy
We present a case of a 3-year-old boy with neurodegeneration.
Family history reveals Rendu-Osler-Weber disease. Magnetic resonance imaging (MRI) of
the spinal cord and spinal angiography showed a spinal arteriovenous fistula with venous aneurysm,
causing compression of the lumbar spinal cord. Embolisation of the fistula was executed, resulting in
clinical improvement. A week after discharge he was readmitted with neurologic regression.
A second MRI scan revealed an intraspinal epidural haematoma and increase in size of the
aneurysm with several new arterial feeders leading to it. Coiling of the aneurysm and fistulas
was performed. Postoperative, the spinal oedema increased despite corticoids, causing more
extensive paraplegia of the lower limbs and a deterioration of his mental state.
A laminectomy was performed and the aneurysm was surgically removed.
Subsequently, the boy recovered gradually. A new MRI scan after two months showed less oedema and a split, partly affected spinal chord. This case shows the importance of excluding possible arteriovenous
malformations in a child presenting with progressive neurodegeneration. In particular when there is a family history
for Rendu-Osler-Weber disease, scans should be performed instantly to rule out this possibility. The case also
highlights the possibility of good recovery of paraplegia in paediatric Rendu-Osler-Weber patients

Paediatric community-acquired septic shock: Results from the REPEM network study
Introduction and purpose of the study With this study we aimed to describe a "true world" picture of severe pae-diatric 'community-acquired' septic shock and establish the feasibility of a future prospective trial on early goal-directed therapy in children. During a 6-month to 1-year retrospective screening period in 16 emergency departments (ED) in 12 different countries, all children with severe sepsis and signs of decreased perfusion were included. Results A 270,461 paediatric ED consultations were screened, and 176 cases were identified. Significant comorbidity was present in 35.8 % of these cases. Intensive care admission was deemed necessary in 65.7 %, mechanical ventilation in 25.9 % and vasoactive medications in 42.9 %. The median amount of fluid given in the first 6 h was 30 ml/kg. The overall mortality in this sample was 4.5 %. Only 1.2 % of the survivors showed a substantial decrease in Paediatric Overall Performance Category (POPC). 'Severe' outcome (death or a decrease ≥2 in POPC) was significantly related (p0.01) to: any desaturation below 90 %, the amount of fluid given in the first 6 h, the need for and length of mechanical ventilation or vasoactive support, the use of dobutamine and a higher lactate or lower base excess but not to any variables of predisposition, infection or host response (as in the PIRO (Predisposition, Infection, Response, Organ dysfunction) concept). Conclusion The outcome in our samplewas very good.Many children received treatment early in their disease course, so avoiding subsequent intensive care. While certain variables predispose children to become septic and shocked, in our sample, only measures of organ dysfunction and concomitant treatment proved to be significantly related with outcome. We argue why future studies should rather be large multinational prospective observational trials and not necessarily randomised controlled trials.©2013 Springer-Verlag Berlin Heidelberg.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
