Improving Prenatal Diagnosis of Coarctation of the Aorta

Background

The purpose of the study was to evaluate the association between fetal echocardiographic measurements and the need for intervention (primary coarctation repair, staged coarctation repair, or catheter intervention) in prenatally diagnosed coarctation of the aorta.

FOLFCIS Treatment and Genomic Correlates of Response in Advanced Anal Squamous Cell Cancer

Background

Treatment of advanced anal squamous cell cancer (SCC) is usually with the combination of cisplatin and 5-fluorouracil, which is associated with heterogeneous responses across patients and significant toxicity. We examined the safety and efficacy of a modified schedule, FOLFCIS (leucovorin, fluorouracil, and cisplatin), and performed an integrated clinical and genomic analysis of anal SCC.

Les auxiliaires à l’intégration scolaire des enfants en situation de handicap. Conditions de travail et développement de compétences professionnelles

Coinciding with the present period of unemployment, a corps of school assistants – assistants de vie scolaire (AVS) – has been created in order to meet the demand for in-school assistance raised by the development of schooling for children with special needs. This paper reports on a questionnaire-based survey carried out among 151 AVS working in the Seine Saint-Denis department. It aims at describing their working conditions considering the precariousness of their status (temporary jobs, poor pay) and the nature of their assignment. The main question bears on whether these conditions enable the assistants to develop the capabilities necessary for dealing with their tasks. Results could contribute to the present issue of reorienting government action in order to improve these jobs in terms of professional development. Notably, they reveal that AVS's training is usually brief and that their opportunities for developing workplace professional relationships are scant even though these are needed for them to collaborate with the other workers concerned by schooling children with special needs.     

Thyroid Artery Erosion by Esophageal Cancer: Management with Interventional Radiology

Management of upper gastrointestinal bleeding because of erosion of vessels by esophageal cancer may be challenging. We present herein the angiographic images of a 49-year-old patient who was admitted with massive bleeding from a tumor-eroded inferior thyroid artery. Attempts to control the bleeding by means of flexible endoscopy and insertion of a Sengstaken–Blakemore tube had failed. The diagnosis was impressively demonstrated by multislice computed tomography with intravenous contrast in the arterial phase and multiplanar reconstructions (computed tomography angiography) and by digital subtraction angiography. The bleeding was successfully treated with superselective catheterization and coiling of the eroded vessel.     

Cytomorphometric analysis of vaginal cells during normal cycle, under oral contraceptive therapy or in-vitro fertilization stimulation protocol

A cytomorphometric analysis of superficial vaginal cells inwomen in three groups of different types of hormonal concentrationwas made. There were 15 women in each group. Group I was studiedduring a natural cycle, group II under oral contraceptive therapyand group III during an in-vitro fertilization (IVF) stimulationprotocol. Morphometric parameters were measured on an imageanalyser. The area, perimeter and several form factors weremeasured separately for nuclei and cytoplasm. The nucleus:cytoplasmicratio was also determined. The cytoplasmic area was significantlyreduced in group II and was associated with a statisticallysignificant reduction of the nuclear area. The nucleus:cytoplasmicratio appeared significantly increased in group II and reducedin group III. Low oestradiol impregnation obtained with an oralminidosed contraceptive interfered with vaginal cell maturation.High oestradiol concentrations obtained during IVF protocolsinduced marked nuclear pycnosis but did not induce supra-physiologicalcell enlargement. Maximal cell size is genetically regulatedaccording to Driesch's law of volume invariance and hormonalover-stimulation has no effect on cell size. The nucleus:cytoplasmicratio appears to be a powerful parameter reflecting the oppositeeffects of hormones on cell compartments.
