The Covid-19 pandemic requires a reliable diagnosis of patients in order to take care of them in the best conditions and in the appropriate services. Moreover, the current diagnostic reference is reverse transcription by polymerase chain reaction (RT-PCR) on a nasopharyngeal sample taken by swab. This technique is expensive (54€) and its production time is several hours. Alternative methods are in progress, including, rapid diagnostic tests. The MEMS microfluids and nanostructures (MMN) laboratory, in partnership with the Institut Chimie Biologie Innovation (CBI) (Paris, 75005), have developed a portable test "COVIDISC", low-cost (10 €), fast (1 hour), including extraction, elution and amplification in solid medium isothermal, reverse amplification loop mediated transcription (RT-LAMP). The "lab" version has received an analytical validation on human nasopharyngeal samples with performance comparable to classic RT-PCR (sensitivity of 7 copies per μl, specificity 100%). The objective of this study is to validate the in vitro diagnostic medical device, COVIDISC, with the standard nasopharyngeal RT-PCR test.
The purpose of this study is to describe the immunological and virological response of patients infected with CoV-2-SARS and presenting an asymptomatic or mildly symptomatic form, in particular the innate and adaptive response as well as the virological clearance kinetics. The research hypothesis is that patients with an ambulatory form of SARS-CoV-2 infection, whether asymptomatic or mildly symptomatic, are able to mount an innate and adaptive immunological response capable of rapidly clearing the virus, in contrast to severe forms in which an early deficit of type 1 IFN response has been demonstrated, possibly responsible for a defect in the control of viral replication in the blood.
The NEOPRENE project proposes to examine processes that are among the earliest precursors of cognitive functions and assess 1) the relationship between neonatal cognitive precursors and cortical structure, structural connectivity and functional connectivity at birth and 2) the relationship between neonatal cognitive precursors and neurodevelopment.
Patients with monoclonal gammopathies either benign or malignant may develop inflammatory symptoms such as Schnitzler syndrome. We proposed to name those cases as monoclonal gammopathy of inflammatory significance, or MGIS. The aim of the study is to search for inflammatory pathway that may be activated in case MGIS and to search if the genetic of tumoral cell could explain those activations.
The oddball paradigm is one of the most widely used methods of brain exploration for the study of attentional processes. It allows the measurement, by means of an Electro-Enchephalogram (EEG), of evoked potentials reflecting the electrophysiological reactivity to the detection of novel stimuli within a stream of standard stimuli. Other studies have recently suggested that, in addition to neuronal activation, certain other physiological processes related to cerebrovascular reactivity, such as the Brain Tissue Pulsatility (BTP), could also be sensitive to various cognitive processes and in particular to attentional processes. In one of the latest studies published in collaboration with our group, it was shown that the amplitude of the electrophysiological response classically associated with attentional activity (P300 wave) was significantly correlated with the amplitude of BTP, suggesting the involvement of cerebrovascular processes in attentional functions. Nevertheless, in this study, the two methods of EEG and Tissue Pulsatility Imaging (TPI) were not synchronized, since TPI was performed at rest and not during the oddball task itself, and to date no study has sought to couple the methods of EEG and ultrasound TPI in an oddball paradigm, for a simultaneous characterization of neuronal and cerebrovascular responsiveness during attentional processes. The general objective of this study will be to evaluate changes in BTP during the detection of novel stimuli in an oddball task in healthy volunteers, in which the two methods of TPI and EEG will be coupled and synchronized.
Cutaneous melanomas represent 4 to 11% of cutaneous cancers, but is responsible for 75% of the deaths reported for these pathologies. The incidence rate double every 10 years. Fourteen thousand cases and 1700 deaths were reported in France in 2015. The local staging of the cancer is represented by the Breslow index, which is measured on histological analysis, corresponding to the maximum depth of the cancer. Breslow index is a good pronostic value, and is used to choose for the best treatment for the patient. Having access to the Breslow index before the first resection of the tumor would allow dermatologists to make a complete resection with the best treatment, and the analysis of the sentinel lymph node, all during the same surgical time. Currently, patients need 2 surgeries : one before the Breslow index, and a second one after. The depth of cutaneous melanoma was already evaluated with High-Frequency Ultrasound (HF-US), but gave disappointing results, with Breslow index not being accurately measured. Only 50% of tumors less than 2mm depth were efficiently measured. Results were even worst for bigger tumors. Ultrasound biomicroscopy (UBM) is a new approach, depending on the use of ultra high frequency and large-band transducer. Nice's CHU acquired the only ultrasound device capable of applying such ultra high frequency ultrasound (UHF-US) to human tissues. The device is a VEVO MD (Vevo MD, Toronto, Canada) and equip the Ultrasound Department since June 2018. The images investigators can assess with this device have an axial resolution of 30µm, for a maximum emission frequency of 70MHz, which was not attainable until this day in human care. Furthermore, when compared to some of the mono-frequency devices investigators experimented before, this device allow investigators to attain a maximum depth of analysis up to 8mm. In consequence, this device seems to be able to realize an extremely precise analysis of the skin, and of the cutaneous melanomas, for a structural analysis, as well as a precise depth measurement, and should be evaluated in the measurement of the Breslow Index. The objective of the study is to analyze the interest of ultrasound biomicroscopy in the pre-therapeutic evaluation of the Breslow index of cutaneous melanoma, compared to histological findings. The study will include 60 patients with cutaneous melanomas, recently diagnosed in the Dermatology Department of the Nice University Hospital (Pr Bahadoran, Pr Passeron, Pr Lacour). Each patient will beneficiate from complete Ultrasound biomicroscopy analysis of the tumor The examination will be made blindly by 2 operator, both with experience in Ultra High frequency Ultrasound examinations (Dr Azulay, Dr Raffaelli). The maximum depth of the melanoma (Breslow index) will be recorded in µm. After surgical resection, the histologic analysis (Dr Long, Pr Hofman, Clinical and Experimental AnatomoPathologic laboratory, Nice's University Hospital) will measure the gold-standard Breslow Index. The comparison will analyze the capacity of Ultrasound biomicroscopy for a precise measurement of the Breslow Index, as well as the inter and intra-operator concordance. If the results of this study are positives and suggest a modification of the therapeutic strategy, a larger multicentric study would be launched in the near future.

The purpose of this study is to isolate and characterize tumor cells non-invasively from biological samples in patients with prostate cancer and demonstrate the ability to identify the presence and number of tumor cells before prostate biopsy.
Wheezing in infants and children less than 3 years of age children is a frequent feature that might be difficult to diagnose when only the caregivers reporting is available. Indeed, in this age group the usual reversible flow limitation measure during pulmonary function testing (PFT) is missing because PFT techniques require the full patient cooperation to perform respiratory tests. Infants PFTs have been developed to measure the same indexes than those measured in adults, but they are difficult to set-up and require medication- induced sleep during day time. However, when flow limitation is sufficient it can be detected during tidal breathing as measured during spirometry using pneumotachograph (PNT). In this test, the tidal breathing flow-volume (TBFV) loop is recorded and studied using different indices to assess the airflow limitation. But, there again, when addressing infants or very young children quiet breathing can only be achieved during sleep and medication- induced sleep necessary. Impedance pneumography (IP) is a method for measuring changes in the thoracic electrical impedance through skin electrodes, which varies as a function of lung aeration i.e. breathing. This technique has mainly been applied to monitor respiratory rate in intensive care settings, but recent technical advancements in IP signal processing and electrode placement strategy have enabled IP to be used for accurate non-invasive tidal flow signal measurement. Compared to direct PNT, high agreement in flow signal and TBFV indices has been demonstrated in young children as well as in infants, even during induced bronchoconstriction. Moreover, in overnight recordings at home, IP was found feasible for quantifying nocturnal TBFV variability in young children with lower respiratory symptoms. In this study, it was shown that preschool children with high risk of asthma present with increased variation of tidal flow profile shape, and momentarily lowered chaoticity, compared to children with lower risk of asthma. Recently a study in Tampere University Hospital (TAUH) Allergy centre (Tampere, Finland, PSHP ethical committee code R14027, ClinicalTrials.gov code NCT02164968) finished collecting overnight TBFV using impedance pneumography on 70 young children with suspected asthma. The preliminary analysis of this data shows that the effect of asthma treatment can be seen in TBFV variability, but to assess the diagnostic capacity of this new method, healthy control sample should be collected. The technology developed by the Finnish medical device company Revenio Research Oy enables to evaluate the variability of the expiratory flow-volume curve. It is calculate as the expiration variability index (EVI) which is decreased in case of bronchoconstriction. In order to explore very young children (less than 3 years of age) unable to participate to any awake lung function test, we set-up a study aiming to: 1) establish reference value for EVI in healthy children 2 months to 3 years old 2) test the variation of EVI in case of acute disease with or without wheezing in this age group children. In this observational prospective multicenter study, we will include 110 asymptomatic healthy subjects to compute reference values of EVI. We will also include 35 previously healthy subjects who have developed an acute non wheezing disease such as fever, rhinitis, otitis or bronchitis to compare their EVI to the reference values. And finally, we will recruit 35 young subjects with an acute wheezing episode. All measurements will be performed at home by the parents, except for some wheezy children who could be hospitalized. It will be proposed to record 2 consecutive nights in healthy asymptomatic children in order to evaluate the night-to-night variability which has already shown to be small in older children. In this multicentre study 120 children will be recruited by the present study in France and the remaining 60 children in another English centre using the same design and technology. It is expected that only children with acute wheezing episode will have a significantly low EVI compare to the reference values established by this study.
