Clinical trials

CERNAS is a prospective, multicenter, non-interventional study comparing the functional and aesthetic outcomes of two rehabilitation strategies after total or subtotal nasal amputation: surgical reconstruction (primarily paramedian forehead flap or free flap) versus nasal epithesis (prosthesis). Patients who have undergone either rehabilitation at least one year prior to enrolment will be invited to complete the validated French version of the SCHNOS (Standardized Cosmesis and Health Nasal Outcomes Survey) questionnaire. The study aims to provide an objective, patient-reported comparison of these two options to guide future clinical decision-making.

In neonatal intensive care, physicians are sometimes confronted with decisions to withhold or withdraw life-sustaining treatment for a critically ill newborn. In France, these decisions are made by the medical team through a formal collegial ("ethics") meeting. Parents are not legally required to take part in this meeting, and their participation remains very rare at the national level. Since 2018, the neonatal intensive care unit of Hopital NOVO (Pontoise site) has systematically offered parents the possibility of attending the collegial ethics meeting concerning their child when withholding or withdrawal of treatment is being considered. This study aims to evaluate the value of parental presence at the ethics meeting in helping parents understand the medical decisions made for their newborn. This is a retrospective, single-centre, non-interventional, qualitative study based on a questionnaire developed specifically for this purpose, in the absence of any validated tool. Parents of newborns for whom an ethics meeting was held between 1 January 2018 and 31 December 2025 are invited to share their experience. Two questionnaire versions are used, one for parents who attended the meeting and one for parents who did not, allowing comparison between the two situations. The questionnaire explores parents' understanding of the decision, the emotional impact of the meeting, their sense of guilt and their acceptance of the decision. Main hypothesis: parental participation in the ethics meeting promotes a better understanding of the medical decision, reduces feelings of guilt, and improves parents' long-term emotional experience.

This retrospective study, aims to evaluate the functional and aesthetic results of lower lip reconstructions, incorporating both patient experiences and the analysis of physicians and surgeons working on facial issues (plastic surgeons and dermatologists) in order to optimize future therapeutic strategies.

This study aims to validate a French version of the Nasal Reconstruction FACE-Q questionnaire for patients who have undergone nasal reconstruction or prosthetic rehabilitation after surgery for nasal skin cancer. The questionnaire evaluates appearance, quality of life, and possible side effects related to the reconstruction. The investigators hypothesize that the validated French version will provide a reliable and standardized tool to assess patient satisfaction and health-related quality of life in this context.

The objective of this study is to determine which of the two techniques (disarticulation septoplasty versus open surgery) offers the best functional results for correcting symptomatic deviations of the nasal septum. More specifically it's about: * Compare the improvement in respiratory symptoms between the two techniques * Analyze and compare complication rates between the two techniques * Evaluate patient satisfaction with aesthetic results (including columella deviation)

The purpose of the study is to recruit as many patients as possible presenting with sacroiliitis or authentic axial spondylarthritis and giant cell arteritis. The investigators will also be interested in the association of spondylarthritis and polymyalgia rheumatica given the continuum between these two pathologies. The aim is to investigate whether there is an association between giant cell arteritis and spondylarthritis or polymyalgia rheumatica and spondylarthritis.

Peripheral venous catheters (PVCs) are the most commonly used intravascular medical devices in healthcare establishments. Although essential in patient care, PVCs represent a significant risk factor for nosocomial infections, as shown by the results of the national prevalence survey. While the main pathophysiological mechanisms are known, the specific factors driving the transition from simple colonization to infection remain unclear. This project aims to identify the major factors involved in the occurrence of bacterial infections related to the colonization of peripheral venous catheters.

The purpose of this study is to evaluate whether the measure of the optic nerve sheath is a reliable diagnostic marker for giant cell arteritis

The aim of this study is to demonstrate, with a good level of evidence, the efficacy, safety and feasibility of placing an umbilical route through Wharton's jelly, in the context of emergency situations in the delivery room.

This prospective study evalue the inflence of pre operative vit D3 administration on post operative hypocalcemia in patients undergoing Total thyroidectomy

The aim of this study is to evaluate the impact of discharge from hospital with a weight of less than 2 kilos. To do this, the investigator will look at the short-term and long-term outcome of newborns weighing less than 2 kilos who were discharged from the neonatology department at the NOVO hospital between 2012 and 2024.

The aim of the study is to measure the number of patients being cared for by a medical team for major trauma who could benefit from a transfusion labile blood products and thus provide a scientific argument in favour of supplying labile blood products to pre-hospital

This study aims to evaluate the average time taken by the Medical Regulation Assistants (MRA) to detect a cardiac arrest during the call to the EMS as well as the factors influencing this delay. Its main objective is to evaluate the delay, in seconds, between the call being picked up and the recognition of a cardiac arrest by the medical regulation assistant at the EMS 95

The aim of this study is to find out whether major trauma patients from the Val d'Oise are referred to the appropriate trauma centre for their care and to assess the quality of triage within the Val d'Oise department.
