Résumé : The physiological ageing, the chronic conditions and the psycho-social environment are source of vulnerability to the old subject. These factors impact on the oral pathologies while the oral affections can deteriorate them on the contrary and lead the patient in the spiral of the decompensation. The clinical examination has to consist of a global approach of the eldely person, what confers it a specific character. Within the framework of this article, we propose a methodology of diagnostic survey bringing to light the necessity of interdisciplinary collaboration between the medical participants
Le vieillissement physiologique, les pathologies chroniques et l’environnement psychosocial sont source de vulnérabilité chez le sujet âgé. Ces facteurs impactent les pathologies bucco-dentaires alors que les affections orales peuvent à l’inverse les aggraver et conduire le patient dans la spirale de la décompensation. L’examen clinique doit consister en une approche globale de la personne âgée, ce qui lui confère son caractère spécifique. Dans le cadre de cet article, nous proposons une méthodologie d’enquête diagnostique mettant en évidence la nécessité de collaboration interdisciplinaire entre les intervenants médicaux

Résumé : International audience
BACKGROUND: The RH blood group system has many RHCE variant alleles that have arisen through gene conversion or nucleotide changes. Two probands, with red blood cells (RBCs) that were D+C+E-c+(w) e+ were sent to our laboratories to resolve the weak c expression. STUDY DESIGN AND METHODS: Hemagglutination tests were performed by automated and manual procedures. Genomic DNA analysis was performed by sequencing of Exons 1 to 10 of RHCE and RHD. RESULTS: The probands' RBCs did not react with standard monoclonal anti-E reagents from Bio-Rad, Diagast, DiaMed, Immucor, Ortho, and Quotient. The RBCs reacted variably with anti-c reagents from Diagast, DiaMed, Immucor, or Ortho and did not react with the Quotient anti-c reagent. Surprisingly, sequencing results of RHCE showed the presence of C/G at Position 676 (E/e polymorphism) and the association of the E polymorphism with a 734T>C transition in Exon 5 of the RHCE, encoding a Leu245Pro amino acid substitution in the mature RhcE polypeptide. Replacement of leucine 245 by proline in the eighth transmembrane domain of the RhcE protein may have a steric effect on the protein such that most anti-E reagents do not bind and the interaction between anti-c and c antigen is also affected. CONCLUSION: We report a novel RHCE*cE allele, RHCE*cE734C, which was assigned the provisional ISBT allele name RHCE*cE.14 or RHCE*03.14. It was found in two probands whose RBCs had weakened c expression and typed E- with conventional anti-E reagents. These data, once again, highlight the fact that the genotype does not always reflect the phenotype.

Résumé : International audience
In intrauterine pregnancies of uncertain viability with a gestational sac without a yolk sac (with a mean of three orthogonal transvaginal ultrasound measurements <25 mm), the suspected pregnancy loss should only be confirmed after a follow-up scan at least 14 days later shows no embryo with cardiac activity (Grade C). In intrauterine pregnancies of uncertain viability with an embryo <7 mm on transvaginal ultrasound, the suspected pregnancy loss should only be confirmed after a follow-up scan at least 7 days later (Grade C). In pregnancies of unknown location after transvaginal ultrasound (i.e. not visible in the uterus), a threshold of at least 3510 IU/l for the serum human chorionic gonadotrophin assay is recommended; above that level, a viable intrauterine pregnancy can be ruled out (Grade C). Postponing conception after an early miscarriage in women who want a new pregnancy is not recommended (Grade A). A work-up for women with recurrent pregnancy loss should include the following: diabetes (Grade A), antiphospholipid syndrome (Grade A), hypothyroidism with anti-thyroid peroxidase (anti-TPO) and anti-thyroglobulin (anti-Tg) antibodies (Grade A), vitamin deficiencies (B9, B12) (Grade C), hyperhomocysteinaemia (Grade C), hyperprolactinaemia (Grade B), diminished ovarian reserve (Grade C), and a uterine malformation or an acquired uterine abnormality amenable to surgical treatment (Grade C). The treatment options recommended for women with a missed early miscarriage are vacuum aspiration (Grade A) or misoprostol (Grade B); and the treatment options recommended for women with an incomplete early miscarriage are vacuum aspiration (Grade A) or expectant management (Grade A). In the absence of both chorioamnionitis and rupture of the membranes, women with a threatened late miscarriage and an open cervix, with or without protrusion of the amniotic sac into the vagina, should receive McDonald cerclage, tocolysis with indomethacin, and antibiotics (Grade C). Among women with a threatened late miscarriage and an isolated undilated shortened cervix (<25 mm on ultrasound), cerclage is only indicated for those with a history of either late miscarriage or preterm delivery (Grade A). Among women with a threatened late miscarriage, an isolated undilated shortened cervix (<25 mm on ultrasound) and no uterine contractions, daily treatment with vaginal progesterone up to 34 weeks of gestation is recommended (Grade A). Hysteroscopic section of the septum is recommended for women with a uterine septum and a history of late miscarriage (Grade C). Correction of acquired abnormalities of the uterine cavity (e.g. polyps, myomas, synechiae) is recommended after three early or late miscarriages (Grade C). Prophylactic cerclage is recommended for women with a history of three late miscarriages or preterm deliveries (Grade B). Low-dose aspirin and low-molecular-weight heparin at a preventive dose are recommended for women with obstetric antiphospholipid syndrome (Grade A). Glycaemic levels should be controlled before conception in women with diabetes (Grade A)
