Orangutans and chimpanzees produce morphologically varied laugh facesin response to the age and sex of their social partners.

Laugh faces of humans play a key role in everyday social interactions as a pervasive tool of communication across contexts. Humans often vary the degree of mouth opening and teeth exposure when producing these facial expressions, which may depend on who their social partner is (e.g.

[Patient-partnership in a comprehensive cancer centre: Establishment and roles of a patients and caregivers committee].

In oncology, the place of patients has a natural and strong legitimacy. Cancer is a common disease, with many singularities but also common features between pathologies, with issues ranging from prevention to possible palliative phases or post-cancer, and conducive to both individual and collective decision-making processes. Patient engagement is now essential at all levels of the healthcare system, from simple information to real involvement (co-construction).

Predators attacking virtual prey reveal the costs and benefits of leadership.

A long-standing assumption in social behavior is that leadership incurs costs as well as benefits, and this tradeoff can result in diversified social roles in groups. The major cost of leadership in moving animal groups is assumed to be predation, with individuals leading from the front of groups being targeted more often by predators. Nevertheless, empirical evidence for this is limited, and experimental tests are entirely lacking.

Tuberculin skin test negativity is under tight genetic control of chromosomal region 11p14-15 in settings with different tuberculosis endemicities.

A substantial proportion of subjects exposed to a contagious tuberculosis case display lack of tuberculin skin test (TST) reactivity. We previously mapped a major locus (TST1) controlling lack of TST reactivity in families from an area in South Africa where tuberculosis is hyperendemic. Here, we conducted a household tuberculosis contact study in a French area where the endemicity of tuberculosis is low.

[Food intake during the previous 24h as a percentage of usual intake: a marker of hypoxia in infants with bronchiolitis: an observational, prospective, multicenter study].

Background: Hypoxia associated with bronchiolitis is not always easy to assess on clinical grounds alone. The aim of this study was to determine the value of food intake during the previous 24h (bottle and spoon feeding), as a percentage of usual intake (24h FI), as a marker of hypoxia, and to compare its diagnostic value with that of usual clinical signs.

Methods: In this observational, prospective, multicenter study, 18 community pediatricians, enrolled 171 infants, aged from 0 to 6 months, with bronchiolitis (rhinorrhea+dyspnea+cough+expiratory sounds).

Probiotics and prebiotics in preventing episodes of acute otitis media in high-risk children: a randomized, double-blind, placebo-controlled study.

Background: Several studies have suggested that probiotics (proB) and/or prebiotics (preB) could reduce the burden of infection in infants and toddlers. We aimed to determine whether follow-up formula supplemented with proB and preB could reduce the risk of acute otitis media (AOM).

Methods: In this double-blind, placebo-controlled trial from November 2007 to April 2009, 37 pediatricians in France enrolled children 7 to 13 months of age with high risk of AOM who were randomly assigned to receive follow-up formula supplemented with proB (Streptococcus thermophilus NCC 2496, Streptococcus salivarius DSM 13084, Lactobacillus rhamnosus LPR CGMCC 1.

[Acceptability, compliance and schedule of administration of oral antibiotics in outpatient children].

Background: Compliance with antibiotics is essential to ensure treatment efficacy and to prevent the emergence of bacterial resistant stains. In children who take oral form, the palatability and the frequency of administration seem to be factors important to good compliance.

Patients And Methods: This observational study was designed to assess the acceptability of oral antibiotics (including generics) commonly prescribed to children by primary care physicians in France.

Local and regional adverse reactions to BCG-SSI vaccination: a 12-month cohort follow-up study.

In a 12-month cohort follow-up study of 2435 children vaccinated in 2007 by Statens Serum Institute BCG strain (BCG SSI, 17.8% had an adverse event (AE): erythema 12.4%, induration 12.

[Epidemiology of pediatric bacterial meningitis in France].

This review of pediatric bacterial meningitis was presented in the 17th French Consensus Conference of antimicrobial chemotherapy. It should contribute to the elaboration of guidelines for the treatment of this disease. The incidence of bacterial meningitis rates is 44/100,000 in children under 1 year of age and 6.

[BCG vaccine coverage in private medical practice: First data in children below two years old, seven months after the end of compulsory vaccination in France].

Objectives: In July 2007, compulsory BCG vaccination for all children was replaced by a strong recommendation to vaccinate children at high risk of tuberculosis (children who live in Ile-de-France [IDF] or Guyana regions, who were born or whose parents were born in tuberculosis endemic countries, with a family history of tuberculosis or living in conditions defined as at risk by the doctor). In the absence of tools to detect an early decrease in vaccine coverage (VC) in this specific group, we conducted a survey with the main objective of measuring BCG VC in high risk children for which BCG is now recommended and who were born after the change in BCG vaccine policy.

Methods: Cross-sectional survey performed amongst physicians registered at "Infovac-France", a network of general practitioners and paediatricians particularly aware of recent changes in the field of vaccinations.

[Clinical outcome and bacterial characteristics of 99 Escherichia coli meningitis in young infants].

Objective: To conduct a descriptive analysis of clinical, biological and prognostic aspects of Escherichia coli meningitis in young infants.

Methods: Clinical and biological data on young infants diagnosed with neonatal E. coli meningitis (NECM) between 1988 and 2004 were collected retrospectively and analyzed with respect to the isolates'phenotypic and genotypic characteristics.

[Pneumococcal meningitis in children in France: 832 cases from 2001 to 2007].

Background: Pneumococcal meningitis represents one major cause of morbidity and mortality in children in France. The GPIP/ACTIV (Groupe de Pathologie Infectieuse Pédiatrique and Association Clinique et Thérapeutique Infantile du Val de Marne) set up an active surveillance network to analyze the clinical and biological features of pneumococcal meningitis and the impact of 7-valent pneumococcal conjugate vaccine (PCV7).

Methods: From 2001 to 2007, 252 French pediatric wards working with 168 microbiology laboratories enrolled all children (0-18 years old) with bacterial meningitis.

[Impact of influenza rapid diagnostic tests (IRDT) on the diagnosis of influenza and on the management of influenza in children in ambulatory pediatric setting].

Objective: Several studies have highlighted the assets of the influenza rapid diagnostic tests (IRDT) for the emergency department management of febrile children. The objective of this study was to determine in ambulatory pediatric setting impact of IRDT on the management of febrile children during an epidemic, especially on other diagnostic testing performed, antibiotic and antiviral treatments.

Methods: During an influenza epidemic, 37 paediatricians in three different areas of France included all children presenting fever with respiratory illnesses; they performed IRDT (test QuickVue for Influenza A and B, Quidel).

Study of the acceptability of antibiotic syrups, suspensions, and oral solutions prescribed to pediatric outpatients.

This observational study was designed to evaluate the acceptability of oral antibiotics (including generics) commonly prescribed to children by community practitioners in France. Between February and July 2006, the parents of 953 children enrolled by 46 pediatricians completed a questionnaire, including a taste assessment based on representations of five facial expressions. The proportions of "satisfactory" taste judgments showed a significant difference between amoxicillin-clavulanate reference product and its generics (77.

Association between mortality of Escherichia coli meningitis in young infants and non-virulent clonal groups of strains.

To identify factors associated with Escherichia coli meningitis (ECM) mortality in infants aged <3 months, the clinical, biological and bacterial characteristics of isolates from 99 cases of ECM were compared, including the phylogenetic group, multilocus sequence type, O serogroup and sequence O type (a combination of sequence type complex (STc) and O serogroup) and virulence genotype. All 99 isolates were susceptible to the initial antimicrobial treatment. The mortality rate (14%) was not influenced by term or post-natal age.

[Evaluation of impact of CRP rapid test in management of febrile children in ambulatory pediatric practice].

Objective: Fever without source (FWS) is a common cause of children visits to pediatric practices. Clinical evaluation does not always rule out efficiently an invasive bacterial infection. Among blood markers, several publications have suggested the value of C-reactive protein (CRP).

Sensitivity of the bacterial meningitis score in 889 children with bacterial meningitis.

Objective: To validate sensitivity of the bacterial meningitis score (BMS) in a large population of children with bacterial meningitis (BM).

Study Design: Secondary analysis of prospective data for children presenting with BM to a hospital emergency department between January 2001 and February 2005. The BMS was applied to all children with acute BM using the same inclusion criteria proposed by the authors of the rule.

Pneumococcal conjugate vaccine does not influence Staphylococcus aureus carriage in young children with acute otitis media.

We investigated nasopharyngeal carriage of Streptococcus pneumoniae and Staphylococcus aureus among infants and young children with acute otitis media in a country where use of 7-valent pneumococcal conjugate vaccine (PCV7) has been progressively implemented. Among 1783 children enrolled, 60.8% carried S.

Pneumococcal meningitis in the era of pneumococcal conjugate vaccine implementation.

The French Pediatric Infectious Diseases Group set up an active surveillance network to analyze the clinical and biological features of pneumococcal meningitis and the impact of the seven-valent pneumococcal conjugate vaccine (PCV7). From 2001 to 2005, 234 pediatric wards working with 166 microbiology laboratories enrolled all children with pneumococcal meningitis. Risk factors, signs and symptoms, vaccination status, cerebrospinal fluid analysis, treatments and case fatality rates were recorded.

[Vaccination in parents of young infants survey].

Since 2004, in France, pertussis booster is recommended in parents of young infants and adults likely to become parents. This recommendation adds to others such as rubella vaccination in unvaccinated or seronegative women and decennial dT-IPV booster. The objective of this study is to evaluate the impact of these recommendations in parents of young infants.

[Impact of the rapid diagnosis downtown in the assumption of responsibility of the children in period of influenza].

Several studies in children showed at the paediatric emergency hospital the interest of influenza rapid diagnostic tests (IRDT) in this disease for which the clinical diagnosis is difficult in children. The purpose of this prospective study carried out in ambulatory paediatric setting was to evaluate impact of the IRDT in the assumption of responsibility of children suspected of Influenza infection. Thirty paediatricians (14 without IRDT, 16 with IRDT) included 602 children between 2004 and 2005.
