    BACKGROUND: Blood tests of liver injury are less well validated in non‐alcoholic fatty liver disease (NAFLD) than in patients with chronic viral hepatitis. AIMS: To improve the validation of three blood tests used in NAFLD patients, FibroTest for fibrosis staging, SteatoTest for steatosis grading and ActiTest for inflammation activity grading. METHODS: We pre‐included new NAFLD patients with biopsy and blood tests from a single‐centre cohort (FibroFrance) and from the multicentre FLIP consortium. Contemporaneous biopsies were blindly assessed using the new steatosis, activity and fibrosis (SAF) score, which provides a reliable and reproducible diagnosis and grading/staging of the three elementary features of NAFLD (steatosis, inflammatory activity) and fibrosis with reduced interobserver variability. We used nonbinary‐ROC (NonBinAUROC) as the main endpoint to prevent spectrum effect and multiple testing. RESULTS: A total of 600 patients with reliable tests and biopsies were included. The mean NonBinAUROCs (95% CI) of tests were all significant (P < 0.0001): 0.878 (0.864–0.892) for FibroTest and fibrosis stages, 0.846 (0.830–0.862) for ActiTest and activity grades, and 0.822 (0.804–0.840) for SteatoTest and steatosis grades. FibroTest had a higher NonBinAUROC than BARD (0.836; 0.820–0.852; P = 0.0001), FIB4 (0.845; 0.829–0.861; P = 0.007) but not significantly different than the NAFLD score (0.866; 0.850–0.882; P = 0.26). FibroTest had a significant difference in median values between adjacent stage F2 and stage F1 contrarily to BARD, FIB4 and NAFLD scores (Bonferroni test P < 0.05). CONCLUSIONS: In patients with NAFLD, SteatoTest, ActiTest and FibroTest are non‐invasive tests that offer an alternative to biopsy, and they correlate with the simple grading/staging of the SAF scoring system across the three elementary features of NAFLD: steatosis, inflammatory activity and fibrosis

    Anorectal malformations: functional prognosis and management of sequelae in the adolescent and the adult

    L'incidence des malformations anorectales est de 1/5 000 naissances. Il s'agit d'un spectre de malformations, classĂ©es en formes basses ou hautes en fonction de leurs caractĂ©ristiques anatomiques et du pronostic de continence fĂ©cale chez le patient atteint. La prise en charge des malformations anorectales Ă  la naissance inclut un bilan complet Ă  la recherche des anomalies associĂ©es (entitĂ© VACTERL). La stratĂ©gie thĂ©rapeutique consiste en une chirurgie en un, deux ou trois temps, en fonction du type anatomique et de la nĂ©cessitĂ© d'une colostomie de protection. Les sĂ©quelles fonctionnelles Ă  long terme et leur prise en charge dĂ©pendent du type malformatif: 1) les formes basses ont un bon pronostic en terme de continence fĂ©cale, mais peuvent ĂȘtre associĂ©es Ă  une constipation sĂ©vĂšre et un mĂ©garectum responsable de pertes fĂ©cales (pseudo-incontinence par regorgement) ; 2) le pronostic des formes hautes est moins bon, avec un risque de dĂ©veloppement d'une incontinence fĂ©cale qu'il est important d'identifier avant l'Ăąge de 5-6 ans de façon Ă  proposer un traitement adĂ©quat visant Ă  assurer une propretĂ© fĂ©cale pendant les pĂ©riodes scolaires (gestion intestinale par lavements Ă©vacuateurs rĂ©trogrades). La rĂ©alisation de lavements coliques antĂ©rogrades par une appendicostomie continente ombilicale permettra ultĂ©rieurement d'accroĂźtre l'autonomie du patient Ă  l'adolescence
