The interplay between the colonic microbiota and gut epithelial and immune cells during the neonatal period, which establishes the structure of the microbiota and programs mucosal immunity, is affected by the diet. We hypothesized that protein-enriched milk formula would disturb this interplay through greater flux of protein entering the colon, with consequences later in life. Piglets were fed from postnatal day (PND) 2 to 28 either a normal-protein formula (NP; 51 g protein/L) or high-protein formula (HP; 77 g protein/L) and weaned at PND28, when they received standard diets until PND160. HP feeding transiently increased the quantity of protein entering the colon (PND7) but did not change the microbiota composition at PND28, except for a higher production of branched-chain fatty acids (BCFAs) in an in vitro fermentation test (P < 0.05). HP piglets had greater colonic mucosa densities of cluster of differentiation (CD) 3+ and CD172+ cells and lower II-1β and Tnfα mRNA levels at PND28 (P < 0.05). Later in life (PND160), HP females, but not males, had a higher increase in colonic permeability after ex vivo oxidative stress and higher cytokine secretion in response to lipopolysaccharide in colonic explant cultures than NP females (P < 0.05). HP females also had lower colonic amounts of F. prausnitzii and BCFAs (P < 0.05). BCFAs displayed a dose-dependent protection against inflammation-induced alteration of barrier function in Caco-2 cells (P < 0.05). In conclusion, protein-enriched formula had little impact on colonicmicrobiota, but it modified colonic immune cell development and had a long-term effect on adult colonic mucosa sensitivity to inflammatory insults, probably through microbiotal and hormonal factors. © 2013 American Society for Nutrition.

Lactate production results from anaerobic glycolysis. This pathway is recruited physiologically during intense and sustained muscular contractions. Hyperlactatemia may develop when tissue oxygenation is jeopardized such as in shock, its absence having been, however, sometimes reported in sepsis in which interactions between infectious agents and the organism's cells might blunt or disrupt hyperlactatemia development. During the course of acute rotavirus gastroenteritis, a 9-month-old girl developed severe dehydration (capillary-refill time, 5s) leading to hypovolemic shock without signs of sepsis and with hypotension at 62/21. mmHg Surprisingly, the child failed to develop hyperlactatemia during shock. An etiologic search to understand why hyperlactatemia did not occur revealed that this patient had been receiving propranolol since the age of four months for the treatment of a Cyrano hemangioma. Via its inhibitory action on β-adrenergic receptors, propranolol antagonizes the stimulation of glycolysis by catecholamines, which may be rationally proposed to have contributed to preventing hyperlactatemia during hypovolemic shock in this patient. Mechanisms by which propranolol can mediate this antihyperlactatemia action are further illustrated and discussed. © 2014 Elsevier Masson SAS.

Critically ill adult patients often require multiple examinations in the hospital and need transport from one department to another, or even between hospitals. However, to date, no guidelines exist regarding optimum practices for transport of these fragile patients. We present recommendations for intrahospital transport of critically ill patients, excluding newborns, developed by an expert group of the French-Language Society of Intensive Care (Société de Réanimation de Langue Française (SRLF), the Société Française d'Anesthésie et de Réanimation (SFAR), and the Société Française de Médecine d'Urgence (SFMU). The recommendations cover five fields of application: epidemiology of adverse events; equipment, monitoring, and maintenance; preparation of patient before transport; human resources and training for caregivers involved in transport processes; and guidelines for planning, structure, and traceability of transport processes. © 2012 Quenot et al.

Introduction - The objective of the SERAC study was to describe the long term handicaps in children severely injured and admitted in intensive care after a road accident. Methods - Children severely injured (Injury severity score, ISS>16) admitted to a paediatric intensive care unit in 2003 and 2004 among 12 French pediatric intensive care units (PICU) were included. A clinical and neuropsychological assessment using standardized and validated scales was performed six months and 12 month after the accident. Results - Among the 139 children included, 31 deceased. Median age was 9 years and median ISS was 27. Among the 108 survivors 89 and 88 were assessed at 6 months and 12 months respectively. Somatic complaints the most frequently reported were fatigue (70%), attention disorders (>60%), behavioural disorders (60%). According to the type of handicap assessed, 25 to 40% of children were disabled. Most of them returned to their previous school, but 20% had difficulties. Familial consequences of these disabilities were frequent and long lasting. Conclusion - The frequency of symptoms reported by parents differed from those of impairments and disabilities assessed by tests. These handicaps had a link with the severity of traumatic brain injury and had a significant impact on family.

We report a case of an immunocompetent child who developed parvovirus B19 infection complicated by autoinflammatory disease with myocarditis, tamponade and macrophage activation syndrome. He recovered with immunotherapy including prednisone, immunoglobulins, cyclosporin and anakinra (anti-interleukin-1). The report shows that parvovirus can provoke severe systemic inflammation with acute heart injury and that anti-interleukin-1 might be considered in such parvovirus-related inflammation.

BACKGROUND: Extrapulmonary complications of Mycoplasma pneumoniae infection are rare and dominated by nervous system disorders. Two patients suffering from acute disseminated encephalomyelitis associated with M. Pneumoniae infection are reported. AIM: Report of two new cases CASES REPORT: The 2 cases, M. Pneumoniae infection was documented by the positivity of serology, polymerase chain reaction and culture in the respiratory tract. Patient 1 recovered after prolonged mechanical ventilation in the paediatric intensive care unit. He was fully conscious 1 month after admission and able to walk with help 2.5 months after the onset of the disease. The 2nd patient died after 9 days of hospitalisation in the intensive care unit. The death was caused by neurovegetative disorders.

We report 2 cases of previously healthy children, who developed, after a common parvovirus B19 infection, a sudden inflammatory response, involving predominantly T cell, directed against myocardium and leading to fatal outcome. These cases and several published case reports further our understanding of fulminating parvovirus myocarditis in children. © 2012 by Lippincott Williams & Wilkins.

Acute respiratory failure in severe disabled people is a frequent and serious complication with a high morbidity and mortality rate. Common management relies on antibiotic therapy combined with clearance of airway secretions. Several manual and instrumental airway clearance techniques can be used to improve patients and tend to avoid mechanical ventilation, which is a controversial ethical issue. Postural changes should be associated with these techniques to decrease muscular contraction and enhance alveolar recruitment. This article is an overview of the most useful airway clearance techniques in disabled patients. © 2015 Elsevier Masson SAS. All rights reserved.

Hemolytic uremic syndrome (HUS) is the primary cause of acute renal failure in children younger than 3 years of age. It usually occurs after a diarrheal illness due to Shiga-toxin-producing Escherichia coli. Streptococcus pneumoniae (SP)-induced HUS remains rare, involving 5% of all cases of HUS in children, but its frequency has increased over the last decade. The incidence of HUS following invasive pneumococcal infections is estimated at 0.4 to 0.6%. We report here the case of a 3.5-year-old child who presented SP serotype-3-associated HUS. The diagnosis was suspected by the patient's multiple organ failure. The pathogenesis involves the activation of the Thomsen-Friedenreich antigen. To prevent transfusion-associated hemolysis, it is recommended that fresh-frozen plasma or unwashed blood products should be avoided when possible. Our patient was transfused with 4 units of unwashed red blood cell and 2 units of fresh-frozen plasma. No special complication was noted. The risk of immediate complications requires close clinical and biological monitoring, and the possibility of starting dialysis immediately. Twenty-five to 35% of SP-HUS patients exhibit long-term renal aftereffects. The acute mortality rate depends on the site of infection. The increased frequency of SP-HUS may be related to the new ecology of serotypes created by widespread Prevenar7 ® vaccination. © 2012 Elsevier Masson SAS.
