Abstract
Abstract
Introduction
Congenital hypothyroidism (CH) is a condition of thyroid hormone deficiency present at birth. Untreated CH results in severe mental impairment. An increased incidence of CH has been reported in France and worldwide that could be explained by an increase in transient forms of CH (TCH). We aimed to estimate the proportion of transient eutopic gland based on the characteristics of children at birth.
Methods
A probabilistic matching data from French CH neonatal screening program and French national health data system (SNDS) of children born between 2006 and 2012 (1, 763 with CH) allowed to linking 484 (68.8%) among 703 children with eutopic gland. Infants with six months or greater discontinuation of levothyroxine (LT4) treatment before the 31th December 2017 were classified transient CH. We used the Cox model to examine the predictors of TCH.
Results
Among infants with eutopic gland, 52.9% were female, 14.9% were preterm and 14, 1 % had low birth weight, 11.8 % had a first degree family history of thyroid diseases, 48.1% of mild CH (TSH<50mU/L) at diagnosis and 30,0μg/j median dose of LT4 treatment. The probability of transient CH at five years of follow-up was 25.3% [IC95%:21.6% -29.4%] and 36.7% [31.7% -42.2%] after ten years. In a cox multivariable analysis, neonates with a TSH<50mU/L (adjusted Hazard Ratio=4.1 [2.8-6.2]) and preterm 1.9 [1.1-3.4] had more risk to be transient.
Conclusions
Prematurity and TSH level were predictors of transient CH. Additional analyses are ongoing to determine whether the occurrence of transient forms of TCH is increasing over the study period.
Key messages
Transient congenital hypothyroidism represent a significant part of HC at 10 years of follow-up. This finding has important implication on medical practices and should trigger research on the etiology of these transient forms.

Abstract
Nano- and micro-photonics are the key-enabling tools for future integrated components and circuitry operating at low power and high speed. By using a strip-loaded platform, we show how we can dramatically reduce the complexity, in terms of fabrication and tolerances, of the most advanced devices. Different configurations of multimode interference devices are presented. We show the design, fabrication, and optical characterization of these components.

Abstract
Every year in France, nearly 50 infants live in a prison nursery with their mother. According to French law, infants can live with their mother in the prison nursery until they reach 18 months of age. The international community is concerned about the lack of validated social, medical and legal data on these infants living in prison. This was a retrospective and descriptive study. Medical and paramedical files of the General Council of Île-et-Vilaine, France, were studied. Every infant born between 1998 and 2013 while their mother was in prison were included. Fifty-four files were collected. The average length of stay was 6.2 months (n=54). The type of the mother's prison sentence was property damage in 40 % of cases, personal injury in 51.1 % of cases and both in 8.9 % of cases (n=45). The length of the mother's imprisonment was on average 45 months, ranging from 3 to 216 months (n=34). After prison, 42.9 % of the infants were placed in foster care and 57.1 % resided with their family (n=42). This child-mother incarceration could be an opportunity for positive intergenerational paramedical, medical and social services. The lack of data and problems collecting data restrict our knowledge of these families. This should motivate a national follow-up for these children.

Abstract
We experimentally demonstrate critical coupling of whispering gallery mode (WGM) disk resonators implemented on a Bloch surface wave platform using scanning near-field optical microscopy. The studied structure is a 60 nm thick TiO2 WGM disk cavity (radius of 100 μm) operating within the C-band telecommunication wavelength. An extinction ratio of 26 dB and a quality factor of 2200 are measured. Such a high extinction ratio verifies the critical coupling of the WGM resonator. This result paves the way to planar optical signal processing devices based on the proposed geometry, for which a critical coupling condition is a guarantee of optimum performance.

Abstract
Neonatal screening for cystic fibrosis (CF) can detect infants with elevated immunoreactive trypsinogen (IRT) levels and inconclusive sweat tests and/or CFTR DNA results. These cases of uncertain diagnosis are defined by (1) either the presence of at most one CF-associated cystic fibrosis transmembrane conductance regulator (CFTR) mutation with sweat chloride values between 30 and 59mmol/L or (2) two CFTR mutations with at least one of unknown pathogenic potential and a sweat chloride concentration below 60mmol/L. This encompasses various clinical situations whose progression cannot be predicted. In these cases, a sweat chloride test has to be repeated at 12 months, and if possible at 6 and 24 months of life along with extended CFTR sequencing to detect rare mutations. When the diagnosis is not definite, CFTR functional explorations may provide a better understanding of CFTR dysfunction. The initial evaluation of these infants must be conducted in dedicated CF reference centers and should include bacteriological sputum analysis, chest radiology, and fecal elastase assay. The primary care physicians in charge of these patients should be familiar with the current management of CF and should work in collaboration with CF centers. A follow-up should be performed in a CF reference center at 3, 6, and 12 months of life and every year thereafter. Any symptom indicative of CF requires immediate reevaluation of the diagnosis. These guidelines were established by the "neonatal screening and difficult diagnoses" working group of the French CF society. Their objective is to standardize the management of infants with unclear diagnosis.

Abstract
Neonatal screening for cystic fibrosis (CF) may detect infants with elevated immunoreactive trypsinogen (IRT) levels but with inconclusive sweat tests and/or DNA results. This includes cases associating (1) either the presence of at most one CF-causing mutation and sweat chloride values between 30 and 59mmol/L or (2) two CFTR mutations with at least one of unknown pathogenicity and a sweat chloride below 60mmol/L. This encompasses different clinical situations whose progression cannot be predicted. These cases require redoing the sweat test at 12 months and if possible at 6 and 24 months of life. This must be associated with extended genotyping. CFTR functional explorations can also help by investigating CFTR dysfunction. These infants must be initially evaluated in dedicated CF centers including bacteriological sputum analysis, chest radiology and fecal elastase dosage. A home practitioner must be informed of the specificity of follow-up. These infants will be reviewed in the CF center at 3, 6 and 12 months and every year. Any CF-related symptom requires reevaluation of the diagnosis. These guidelines were established by the "neonatal screening and difficult diagnoses" working group of the French CF Society. They aim to standardize management of infants with unclear diagnosis in French CF centers.

Abstract
We present, to the best of our knowledge, the first experimental investigation of a two-dimensional disk resonator on a dielectric multilayer platform sustaining Bloch surface waves. The disk resonator has been patterned into a few tens of nanometer thin (∼λ/25) titanium dioxide layer deposited on the top of the platform. We characterize the disk resonator by multi-heterodyne scanning near-field optical microscopy. The low loss characteristics of Bloch surface waves allowed us to reach a measured quality factor of 2×103 for a disk radius of 100 μm.

Abstract
BACKGROUND AND AIMS On 5 March 2007 the law concerning the child protection system was reformed. Since this date, child protection services are responsible for child abuse and neglect. Child protection services are now attempting to determine the rightful place for parents. Asking for child protection is now easier for the general practitioner (GP), who can submit a "preoccupying information (PI)" form. The aim of this study was to review GPs' knowledge on this issue 6 years after the passage of this new law. METHODS Prospective postal investigation between 04/01/2013 and 06/01/2013. RESULTS A total of 298 (113 women) of the 899 GPs of the Ille-et-Vilaine area in Brittany answered a few questions about their activity and their knowledge on child abuse and neglect. The sample's mean age, sex, and practice was representative of the GPs in this area. Only 25.5% of the GPs had any knowledge of this new law. The term "preoccupying information" was unfamiliar to 70.1% of the GPs and what to do with the PI was unknown to 77.2%. The GPs did not know which type of letter to send nor where to send it between legal child protection and social protection services. Only 5% of the GPs had child protection training on PI. The main problem informing the child protection services was the lack of training. Consequently, 91.9% of the GPs would like training. CONCLUSIONS The GPs in the Ille-et-Vilaine area in Brittany are unfamiliar with the child protection updates and need special training.

Abstract
In this study, slot waveguide ring resonators patterned on a silicon-on-insulator (SOI) wafer and coated with an atomic layer deposited nanolaminate consisting of alternating layers of tantalum pentoxide and polyimide were fabricated and characterized. To the best of our knowledge, this is the first demonstration of atomic layer deposition (ALD) of organic materials in waveguiding applications. In our nanolaminate ring resonators, the optical power is not only confined in the narrow central air slot but also in several parallel sub-10 nm wide vertical polyimide slots. This indicates that the mode profiles in the silicon slot waveguide can be accurately tuned by the ALD method. Our results show that ALD of organic and inorganic materials can be combined with conventional silicon waveguide fabrication techniques to create slot waveguide ring resonators with varying mode profiles. This can potentially open new possibilities for various photonic applications, such as optical sensing and all-optical signal processing.

Abstract
BACKGROUND Shaken baby syndrome (SBS) is defined by the association of intracranial hemorrhage and retinal hemorrhage in infants under 2 years of age, with no obvious external trauma. This syndrome leads to frequent neurological sequelae. Therefore, these infants can claim compensation for damage if sequelae are directly and irrefutably linked to the trauma. Data on the judicial treatment are for the most part inexistent in the medical literature, the reason for which this study was conducted. POPULATION AND METHODS We conducted a retrospective study over a period of 10 years. We included all cases of SBS reported to the High Courts of the Ille-et-Vilaine department (Rennes and St Malo). The cases were listed from the archives of the Department of Medical Information, the Specialized Unit for Abused Children and Forensic Department at the Rennes University Hospital. We were able to look the judicial cases up after receiving agreement from the prosecutors of the two courts. RESULTS Of the 34 cases included, 12 could not be used (lost, ongoing, destroyed, transferred to another court), 16 led to an order of dismissal or to no further action because of an unknown perpetrator, insufficiently described offense, or insufficient evidence. Six authors were sentenced. It was the father (n=5) or the childminder (n=1). All perpetrators had confessed to part or all of the charges brought against them. Five children received compensation: three by the civil court and two by the commission of compensation for victims of an offense. CONCLUSION Most cases led to no conviction and no compensation. The identification by the physician of the person responsible for the lesions in SBS does not mean that the perpetrator will be convicted because of the strict application of criminal law. The nomination of an administrator representing the infant could resolve the lack of compensation.

Abstract
Newborn screening (NBS) enables detection of pre-symptomatic cystic fibrosis (CF) patients. A major issue confronting the multidisciplinary team is that of implementing adequate follow-up care, thereby preventing nutritional and pulmonary complications. NBS may also identify newborns who do not fulfil the CF diagnosis criteria; the clinician and family are faced with the diagnostic and prognostic dilemma of atypical CF. Published recommendations are mainly a consensus of expert opinions on follow-up modalities and treatment to help families and primary care physicians, thus harmonizing current practices among CF care specialists. Well-designed clinical trials for these young children focusing on nutritional and pulmonary function are of crucial importance. Indeed, evaluation of pulmonary function is hampered by the absence of accurate, sensitive, reproducible outcome parameters. The European Cystic Fibrosis Society Clinical Trials Network is actively stimulating clinical research on these very young patients.

Abstract
BACKGROUND Limited knowledge exists on phenotypes associated with the D1152H cystic fibrosis transmembrane conductance regulator (CFTR) mutation. METHODS Subjects with a D1152H allele in trans with another CFTR mutation were identified using the French Cystic Fibrosis Registry. Phenotypic characteristics were compared with those of pancreatic insufficient (PI) and pancreatic sufficient (PS) cystic fibrosis (CF) subjects in the Registry (CF cohort). RESULTS Forty-two subjects with D1152H alleles were identified. Features leading to diagnosis included chronic sinopulmonary disease (n = 25), congenital absence of the vas deferens (n = 11), systematic neonatal screening (n = 4), and genetic counseling (n = 2). Median age at diagnosis was 33 [interquartile range (IQR, 24-41)] years in D1152H subjects. Median sweat chloride concentrations were 43.5 (39-63) mmol/l in D1152H subjects and were markedly lower than in PI and PS CF subjects (p < 0.05). Bronchiectasis was present in 67% of D1152H subjects, but Pseudomonas aeruginosa colonization and pancreatic insufficiency were present in <30% of subjects. Estimated rates of decline in forced expiratory volume in 1 s (FEV(1)) were lower in D1152H subjects vs PI CF subjects (p < 0.05). None of the D1152H subjects identified since 1999 had died or required lung transplantation. CONCLUSIONS When present in trans with a CF-causing mutation, D1152H causes significant pulmonary disease, but all subjects had prolonged survival.

Abstract
Congenital long QT syndrome (LQTS) is an inherited arrhythmia that can be sporadic or familial. It predisposes to sudden cardiac death by ventricular fibrillation, which can occur at any age, particularly in neonates. Recent postmortem molecular screening surveys have shown that 10 to 12% of sudden infant death syndrome (SIDS) cases were potentially related to congenital long QT syndrome. Current SIDS etiological surveys fail to diagnose LQTS. Specific questioning and electrocardiographic screening of first-degree relatives could greatly facilitate LQTS diagnosis. We propose adding these to screening modalities after a SIDS incident. Neonatal electrocardiographic screening could allow early identification of LQTS and adapted treatment and follow-up.

Abstract
In 2002 France implemented a nationwide newborn screening program for cystic fibrosis (CF). The strategy combined immunoreactive trypsinogen and, in case of a value over the cut-off level, DNA analysis in dried blood samples at day 3. Data were centralized and periodically analyzed thus maintaining the percentage of samples requiring mutation analysis (0.6%), limiting the number of false-positive cases (0.1%) without increasing the number of false-negative cases (3.2%). 3.527.353 infants were screened between 2002 and 2006. The overall cystic fibrosis incidence was 1/ 4136 with a wide range of regional variations. Dilemma case presentation occurred for 14 % of the patients; an European working group is actively working on this topic, attempting to establish a consensus on the adequate procedures. Cystic fibrosis newborn screening is feasible all over a nation but needs a strong organization from maternity wards to CF care centers.

Abstract
In this paper, we present the optical response of a tunable lithium niobate photonic crystal (PC) using the electro-optic effect of the material. The band gap tunability is 300 times higher than what one could expect for a bulk lithium niobate device of the same characteristics. Theoretical calculations based on the finite-difference time domain technique have allowed us to determine the physical origin of this enhanced electro-optic coefficient. Indeed, the effective second-order susceptibility in the LN nanostructure increases, giving rise to an ultra-compact low-voltage photonic crystal modulator when it operates at its band edge. In addition, the theoretical and far-field transmission results are confirmed by near-field optical microscopy images of the structure at different excitation voltages.

Abstract
Newborn screening (NBS) of cystic fibrosis (CF) was implemented throughout the whole of France in 2002, but it had been established earlier in three western French regions. It can reveal atypical CF with one or two known CFTR mild mutations, with an uncertain evolution. The sweat test can be normal or borderline. In Brittany, from 1989 to 2004, 196 CF cases were diagnosed (1/2885 births). The incidence of atypical CF diagnosed by NBS is 9.7% (19 from 196). The outcome of 17 (2 lost of view) has been studied, with 9 other atypical CF cases diagnosed by NBS in two other regions. The follow-up period extends from 0.25 to 19.8 years (NBS implemented in Normandy in 1980) with mean age 4.6 years. The most frequent mild mutation is R117H ISV8-7T (50%). At the time of the last visit, nutritional status is normal. All these CF patients are pancreatic sufficient. Only one patient exhibits respiratory infections, whereas 7 others have them intermittently. Two of them had intermittent Pseudomonas aeruginosa colonization at 2.8 and 6.5 years. Mean Shwachman score is 96.7, mean Brasfield score is 22.8. Eight children have had lung function tests (mean follow-up of 10 years): mean FVC was 99% of predicted, mean FEV1 101%, but one of them has FEV1 of 48%. Predicting the phenotype of these atypical CF patients remains difficult, thus complicating any genetic counselling. A regular clinical evaluation is necessary, if possible by a CF unit, because CF symptoms may appear later.

Abstract
OBJECTIVES To report longitudinal assessment of pulmonary function in children with neonatal screening for cystic fibrosis and its relationships with Pseudomonas aeruginosa (PA) chronic infection, nutritional status, sex, age and genotype. POPULATION AND METHODS Children benefited systematically of 3 visits a year with pulmonary function tests (PFT) and bacteriological examination. Forty children and 744 PFTs were analysed, with 38 children during at least 4 years. RESULTS We reported a decrease of pulmonary function tests with chronic PA infection and the genotype DeltaF508/DeltaF508. The decline was gradual and not different between not infected and recently infected children. The PFTs of children infected for a long times were very deteriorate, probably due to the fact that they were infected with multiresistant strains of PA. CONCLUSION We think that it is important to survey pulmonary function before 5 years old in these early infected children. We should determinate if the important decrease of PFT in these early infected children is due to infection by PA mucoid.

Abstract
OBJECTIVES To evaluate the performance of a strategy in which, after immunoreactive trypsinogen (IRT) determination, genetic analysis is replaced by a biological test, the pancreatitis-associated protein (PAP) enzyme-linked immunosorbent assay (ELISA). STUDY DESIGN The French newborn screening program includes cystic fibrosis (CF) screening by the IRT/CFTR mutation strategy. PAP was assayed on screening cards, in parallel with IRT, in all newborns from 5 French regions (n = 204,749). Analysis of PAP values in CF and non-CF newborns with elevated IRT allowed direct comparison between the current strategy and the proposed IRT/PAP strategy. RESULTS A protocol in which newborns with IRT >50 ng/mL and PAP >1.8 ng/mL and those with IRT >100 ng/mL and PAP >1.0 ng/mL are directly recalled for sweat testing would have the same performance as the IRT/CFTR mutation strategy. CONCLUSIONS The IRT/PAP strategy is an alternative for CF newborn screening, which avoids the drawbacks of genetic analysis and is cheaper and easier to implement than the current IRT/CFTR mutation strategy.
