Aims: The aims of this study were to compare short-and long-term outcomes for clinical T2N0 oesophageal cancer with analysis of (i) primary surgery (S) versus neoadjuvant therapy plus surgery (NS), (ii) squamous cell carcinoma and adenocarcinoma subsets; and (iii) neoadjuvant chemoradiotherapy versus neoadjuvant chemotherapy.Methods: Data were collected from 30 European centres from 2000 to 2010. Among 2944 included patients, 355 patients (12.1%) had cT2N0 disease; 285 (S) and 70 (NS), were compared in terms of short-and long-term outcomes. Propensity score matching analyses were used to compensate for differences in baseline characteristics.Results: No significant differences between the groups were shown in terms of in hospital morbidity and mortality. Nodal disease was observed in 50% of S-group at the time of surgery, with 20% pN2/N3. Utilisation of neoadjuvant therapy was associated with significant tumour downstaging as reflected by increases in pT0, pN0 and pTNM stage 0 disease, this effect was further enhanced with neoadjuvant chemoradiotherapy. After adjustment on propensity score and confounding factors, for all patients and subset analysis of squamous cell and adenocarcinoma, neoadjuvant therapy had no significant effect upon survival or recurrence (overall, loco-regional, distant or mixed) compared to surgery alone. There were no significant differences between neoadjuvant chemotherapy and chemoradiotherapy in short-or long-term outcomes.Conclusion: The results of this study suggest that a surgery alone treatment approach should be recommended as the primary treatment approach for cT2N0 oesophageal cancer despite 50% of patients having nodal disease at the time of surgery.

Résumé : International audience
Treacher Collins/Franceschetti syndrome (TCS; OMIM 154500) is a disorder of craniofacial development belonging to the heterogeneous group of mandibulofacial dysostoses. TCS is classically characterized by bilateral mandibular and malar hypoplasia, downward-slanting palpebral fissures, and microtia. To date, three genes have been identified in TCS:,TCOF1, POLR1D, and POLR1C. We report a clinical and extensive molecular study, including TCOF1, POLR1D, POLR1C, and EFTUD2 genes, in a series of 146 patients with TCS. Phenotype-genotype correlations were investigated for 19 clinical features, between TCOF1 and POLR1D, and the type of mutation or its localization in the TCOF1 gene. We identified 92/146 patients (63%) with a molecular anomaly within TCOF1, 9/146 (6%) within POLR1D, and none within POLR1C. Among the atypical negative patients (with intellectual disability and/or microcephaly), we identified four patients carrying a mutation in EFTUD2 and two patients with 5q32 deletion encompassing TCOF1 and CAMK2A in particular. Congenital cardiac defects occurred more frequently among patients with TCOF1 mutation (7/92, 8%) than reported in the literature. Even though TCOF1 and POLR1D were associated with extreme clinical variability, we found no phenotype-genotype correlation. In cases with a typical phenotype of TCS, 6/146 (4%) remained with an unidentified molecular defect.

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)
