Abstract
PURPOSE Intracranial aneurysm detection from 3D Time-Of-Flight Magnetic Resonance Angiography images is a problem of increasing clinical importance. Recently, a streak of methods have shown promising performance by using segmentation neural networks. However, these methods may be less relevant in a clinical settings where diagnostic decisions rely on detecting objects rather than their segmentation. METHODS We introduce a 3D single-stage object detection method tailored for small object detection such as aneurysms. Our anchor-free method incorporates fast data annotation, adapted data sampling and generation to address class imbalance problem, and spherical representations for improved detection. RESULTS A comprehensive evaluation was conducted, comparing our method with the state-of-the-art SCPM-Net, nnDetection and nnUNet baselines, using two datasets comprising 402 subjects. The evaluation used adapted object detection metrics. Our method exhibited comparable or superior performance, with an average precision of 78.96%, sensitivity of 86.78%, and 0.53 false positives per case. CONCLUSION Our method significantly reduces the detection complexity compared to existing methods and highlights the advantages of object detection over segmentation-based approaches for aneurysm detection. It also holds potential for application to other small object detection problems.

Abstract
The Kondo effect, deriving from a local magnetic impurity mediating electron-electron interactions, constitutes a flourishing basis for understanding a large variety of intricate many-body problems. Its experimental implementation in tunable circuits has made possible important advances through well-controlled investigations. However, these have mostly concerned transport properties, whereas thermodynamic observations - notably the fundamental measurement of the spin of the Kondo impurity - remain elusive in test-bed circuits. Here, with a novel combination of a 'charge' Kondo circuit with a charge sensor, we directly observe the state of the impurity and its progressive screening. We establish the universal renormalization flow from a single free spin to a screened singlet, the associated reduction in the magnetization, and the relationship between scaling Kondo temperature and microscopic parameters. In our device, a Kondo pseudospin is realized by two degenerate charge states of a metallic island, which we measure with a non-invasive, capacitively coupled charge sensor. Such pseudospin probe of an engineered Kondo system opens the way to the thermodynamic investigation of many exotic quantum states, including the clear observation of Majorana zero modes through their fractional entropy.

Abstract
The scattering of exotic quasiparticles may follow different rules than electrons. In the fractional quantum Hall regime, a quantum point contact (QPC) provides a source of quasiparticles with field effect selectable charges and statistics, which can be scattered on an 'analyzer' QPC to investigate these rules. Remarkably, for incident quasiparticles dissimilar to those naturally transmitted across the analyzer, electrical conduction conserves neither the nature nor the number of the quasiparticles. In contrast with standard elastic scattering, theory predicts the emergence of a mechanism akin to the Andreev reflection at a normal-superconductor interface. Here, we observe the predicted Andreev-like reflection of an e/3 quasiparticle into a - 2e/3 hole accompanied by the transmission of an e quasielectron. Combining shot noise and cross-correlation measurements, we independently determine the charge of the different particles and ascertain the coincidence of quasielectron and fractional hole. The present work advances our understanding on the unconventional behavior of fractional quasiparticles, with implications toward the generation of novel quasi-particles/holes and non-local entanglements.

Abstract
Abstract
Background
Acrylamide is classified as a probable human carcinogen by the IARC but epidemiological evidence on the carcinogenicity of acrylamide from dietary sources is limited. This study aimed to investigate the associations between dietary acrylamide and breast cancer risk in the NutriNet-Santé cohort.
Methods
This prospective cohort study included 80,597 French women (mean [SD] age at baseline: 40.8 [14] years) during a mean (SD) follow-up of 8.8 (2.3) years. Acrylamide intake was evaluated using repeated 24h dietary records (n = 5.5 [SD 3.0]), linked to a comprehensive food composition database. Associations between acrylamide intake and breast cancer risk (overall, premenopausal and post-menopausal) were assessed by Cox hazard models adjusted for known risk factors.
Results
The mean (SD) dietary acrylamide intake was 30.1 (21.9) µg/d (main contributors: coffee, potato fries and chips, pastries and cakes, and bread). During follow-up, 1016 first incident breast cancer cases were diagnosed (431 premenopausal, 585 postmenopausal). A borderline significant positive association was observed between acrylamide intake and breast cancer risk overall (HRQ4 vs Q1= 1.21 [95% CI: 1.00-1.47]) and a positive association was observed with premenopausal cancer (HRQ4 vs Q1= 1.40 [95% CI: 1.04-1.88]). Restricted cubic spline analyses suggested evidence for non-linearity of these associations, with higher HR for intermediate (Q2) and high (Q4) exposures. Receptor-specific analyses revealed a positive association with estrogen receptor-positive breast cancer, which represented 86% of total cancer cases. Acrylamide intake was not associated with post-menopausal breast cancer.
Conclusions
Results from this large prospective cohort study suggest the potential deleterious role of dietary acrylamide in breast cancer etiology, especially in premenopausal women, and provide new insights that should encourage further mitigation strategies to reduce the content of acrylamide in food.

Abstract
Abstract
Background
Food additive emulsifiers are found in thousands of industrial foods and may exert deleterious effects on gut microbiota and carcinogenesis according to experimental studies. However, their associations with cancer risk has not been investigated yet. This study aimed to investigate these associations in a large population-based prospective cohort.
Methods
This study included 102,485 French adults from the NutriNet-Santé cohort (42.1y [14.5], 78.8% female, 2009-2021). Food additive emulsifier intakes were estimated using repeated 24h dietary records linked to brand-specific food composition databases on food additives. Associations with incident cancer risk were assessed using Multivariable Cox models.
Results
3,511 incident cancer cases were diagnosed during follow-up (1,026 breast, 431 prostate, and 279 colorectal cancers). Intakes of sodium citrate (E331, HR = 1.12 [1.02-1.23], p-trend=0.009), xanthan gum (E415, HR = 1.11 [1.02-1.21], p-trend=0.02), and mono- and diglycerides of fatty acids (E471, HR = 1.17 [1.06-1.28], p-trend=0.001 and total: E471, E472a-b-c-e, HR = 1.11, [1.02-1.22], p-trend=0.02) were associated with increased overall cancer risk. Higher intakes of E331 (p-trend = 0.046), sodium stearoyl-2-lactylate (E481, p-trend=0.01), total lactylates (E481-482, p-trend=0.01), total celluloses (E460-468, p-trend=0.03), carob bean gum (E410, p-trend=0.01), and E471 (p-trend=0.006) were associated with increased overall breast cancer risk. Higher intakes of carrageenan (E407, p-trend=0.04), E415 (p-trend=0.02), and triphosphates (E451, p-trend=0.03) were associated with increased post-menopausal breast cancer risk.
Conclusions
These results are the first to investigate and report direct associations between cancer risk and exposures to seven individual and three groups of food additive emulsifiers. If replicated, they may have an important public health impact, considering the omnipresence of these additives in industrial foods globally.
Key messages
• This study is the first to precisely assess exposures to food additive emulsifiers in a population-based study.
• Intakes of food additive emulsifiers were associated with increased risk of cancer.

Abstract
Fractional entropy is a signature of nonlocal degrees of freedom, such as Majorana zero modes or more exotic non-Abelian anyons. Although direct experimental measurements remain challenging, Maxwell relations provide an indirect route to the entropy through charge measurements. Here we consider multichannel charge-Kondo systems, which are predicted to host exotic quasiparticles due to a frustration of Kondo screening at low temperatures. In the absence of experimental data for the charge occupation, we derive relations connecting the latter to the conductance, for which experimental results have recently been obtained. Our analysis indicates that Majorana and Fibonacci anyon quasiparticles are well developed in existing two- and three-channel charge-Kondo devices, and that their characteristic k_{B}logsqrt[2] and k_{B}log[(1+sqrt[5])/2] entropies are experimentally measurable.

Abstract
Abstract
Nitrates and nitrites occur naturally in water and soil and are commonly ingested from water and dietary sources. They are also frequently used as food additives mainly in processed meats. Experimental data consistently suggest their involvement in carcinogenesis but human data is still limited. The aim was to investigate the relationship between nitrate and nitrite intakes and the risk of cancer in a large prospective cohort with detailed and up-to-date dietary assessment. Overall, 101,056 adults from the French NutriNet-Santé cohort study (2009-ongoing) were included. Consumption of nitrites and nitrates was evaluated using repeated 24h dietary records, linked to a comprehensive food composition database which includes details of commercial names/brands of industrial products. Prospective associations between nitrite and nitrate exposures and the risk of cancer were assessed by multivariable Cox hazard models. During follow-up, 3311 first incident cancer cases were diagnosed. Compared with non-consumers, higher consumers of nitrates as food additives had higher risk of breast cancer (HR = 1.24 (1.03-1.48), P = 0.02); this was more specifically observed for potassium nitrate e252, P = 0.01). Higher consumers of nitrites as food additives, and specifically for sodium nitrite (e250), had a higher risk of prostate cancer (HR = 1.58 (1.14-2.18), P = 0.008 and HR = 1.62 (1.17-2.25), P = 0.004, respectively). No significant association was observed for nitrates and nitrites from natural sources. In this large prospective cohort, nitrates as food additives were positively associated with breast cancer risk and nitrites as food additives were positively associated with prostate cancer risk. While these results need confirmation in other large-scale prospective studies, they provide new insights in a context of lively debate around the ban of nitrite additives in food products.

Abstract
When assembling individual quantum components into a mesoscopic circuit, the interplay between Coulomb interaction and charge granularity breaks down the classical laws of electrical impedance composition. Here we explore experimentally the thermal consequences, and observe an additional quantum mechanism of electronic heat transport. The investigated, broadly tunable test-bed circuit is composed of a micron-scale metallic node connected to one electronic channel and a resistance. Heating up the node with Joule dissipation, we separately determine, from complementary noise measurements, both its temperature and the thermal shot noise induced by the temperature difference across the channel. The thermal shot noise predictions are thereby directly validated, and the electronic heat flow is revealed. The latter exhibits a contribution from the channel involving the electrons' partitioning together with the Coulomb interaction. Expanding heat current predictions to include the thermal shot noise, we find a quantitative agreement with experiments.

Abstract
The Coulomb interaction generally limits the quantum propagation of electrons. However, it can also provide a mechanism to transfer their quantum state over larger distances. Here, we demonstrate such a form of electron teleportation across a metallic island. This effect originates from the low-temperature freezing of the island's charge Q which, in the presence of a single connected electronic channel, enforces a one-to-one correspondence between incoming and outgoing electrons. Such faithful quantum state imprinting is established between well-separated injection and emission locations and evidenced through two-path interferences in the integer quantum Hall regime. The additional quantum phase of 2πQ/e, where e is the electron charge, may allow for decoherence-free entanglement of propagating electrons, and notably of flying qubits.

Abstract
Abstract
A total of 17 laboratories (including one author's laboratory) participated in a collaborative study for determination of lysine, methionine, and threonine in trade products or concentrated amino acid premixes. Thirteen samples, 4 pure amino acids and 6 premixes, including 3 Youden matched pairs, were analyzed. The applied liquid chromatographic (LC) method using cation-exchange resin and post-column derivatization with ninhydrin or o-phthaldialdehyde was shown to be accurate and specific for the analytes. Titration procedures, normally used for the assay of pure amino acids, are unspecific and the accuracy of the results can be affected by impurities. Repeatability relative standard deviations, RSDr, ranged from 0.84 to 1.17% for pure amino acids and from 0.50 to 1.68% for premixes; reproducibility relative standard deviations RSDR, ranged from 1.52 to 2.31% for pure amino acids and from 1.48 to 2.59% for premixes. Recoveries were between 97.5 and 102.8% of the expected amino acid assays. The method has been adopted Official First Action status by AOAC INTERNATIONAL.

Abstract
The number of older siblings a child has is negatively correlated with the child’s verbal skills, perhaps because of competition for parents’ attention. In the current study, we examined the role of siblings’ sex and age gap as moderating factors, reasoning that they affect older siblings’ tendency to compensate for reduced parental attention. We hypothesized that children with an older sister have better language abilities than children with an older brother, especially when there is a large age gap between the two siblings. We reanalyzed data from the EDEN cohort ( N = 1,154) and found that children with an older sister had better language skills than those with an older brother. Contrary to predictions, results showed that the age gap between siblings was not associated with language skills and did not interact with sex. Results suggest that the negative effect of older siblings on language development may be entirely due to the role of older brothers. Our findings invite further research on the mechanisms involved in this effect.

Abstract
OBJECTIVE The main endpoint was to perform a survey about the practices of episiotomy into a CNGOF (National College of French Obstetricians and Gynecologists) members population. METHODS In November 2018, it was proceeded to a national survey from CNGOF members thanks to an online questionnaire. We collected prospectively: the answerer's characteristics, the rate of episiotomy and its systematics indications for spontaneous and operative delivery, the habits of the practitioners for the section and the reparation, the modalities of women's information and the data entered into the medical record. RESULTS Three hundred and eighty nine CNGOF members answered to the survey. They were 69% to declare performing less than 10% of episiotomy in case of spontaneous vertex delivery. The most frequent systematic indication of episiotomy was the personal history of obstetric anal sphincter injury (more than 30% of answerers). Systematic episiotomy was less frequent in case of vacuum assisted operative delivery compared to forceps (OR=0.18 [0.08-0.37]) or spatulas (OR=0.28 [0.12-0.59]). Most of practitioners (94%) declared performing mediolateral episiotomies, 64% declared cutting with an equal or more than 45° angle and 50% declared using a resorbable continuous suture technique for the reparation. Half of the answerers (46%) indicated that they inform et collected women's consent before performing an episiotomy. CONCLUSIONS Several practices, women's information, section angle and the reparation technique are subject to change by the latest 2018 CNGOF guidelines about perineal protection.

Abstract
OBJECTIVES To analyze literature, rules, and practices concerning woman's information on labour and delivery. METHODS An actualized systematic review of French rules and guidelines, as well as literature, on patient's information, shared decision-making, and patient's autonomy was done. RESULTS After a reminder on basis of patient's information, notions on patient's autonomy, consent to care, and shared decision-making are developed. Lastly, the role of information documents and birth plan are clarified, as well as rules and guidelines for an efficient conception of the information documents that will result from the present clinical practice guidelines on perineal prevention and protection in obstetrics. CONCLUSION During pregnancy, and again in the labour room, it is recommended to focus on the woman's expectations and to inform her about the modes of delivery. Because she has seen several healthcare professionals during pregnancy, it is necessary to inquire about the information she has already received in order to adapt further information to her situation and current knowledge. This information can be delivered in several forms and by several sources; it should be completed by individualized oral information provided by the healthcare professionals attending her during her prenatal care and during labour. If the woman wants to develop a birth plan, it should be constructed in a supported process that allows the sharing of her knowledge and expectations and of appropriate information delivered by professionals, ideally beginning with the early prenatal interview and continuing during antenatal consultations and sessions of preparation for childbirth and parenting.

Abstract
INTRODUCTION The objective of these clinical practice guidelines was to analyse all of the interventions during pregnancy and childbirth that might prevent obstetric anal sphincter injuries (OASIS) and postnatal pelvic floor symptoms. MATERIAL AND METHODS These guidelines were developed in accordance with the methods prescribed by the French Health Authority (HAS). RESULTS A prenatal clinical examination of the perineum is recommended for women with a history of Crohn's disease, OASIS, genital mutilation, or perianal lesions (professional consensus). Just after delivery, a perineal examination is recommended to check for OASIS (Grade B); if there is doubt about the diagnosis, a second opinion should be requested (GradeC). In case of OASIS, the injuries (including their severity) and the technique for their repair should be described in detail (GradeC). Perineal massage during pregnancy must be encouraged among women who want it (Grade B). No intervention conducted before the start of the active phase of the second stage of labour has been shown to be effective in reducing the risk of perineal injury. The crowning of the baby's head should be manually controlled and the posterior perineum manually supported to reduce the risk of OASIS (GradeC). The performance of an episiotomy during normal deliveries is not recommended to reduce the risk of OASIS (Grade A). In instrumental deliveries, episiotomy may be indicated to avoid OASIS (GradeC). When an episiotomy is performed, a mediolateral incision is recommended (Grade B). The indication for episiotomy should be explained to the woman, and she should consent before its performance. Advising women to have a caesarean delivery for primary prevention of postnatal urinary or anal incontinence is not recommended (Grade B). During pregnancy and again in the labour room, obstetrics professionals should focus on the woman's expectations and inform her about the modes of delivery.

Abstract
Quantum phase transitions (QPTs) are ubiquitous in strongly correlated materials. However, the microscopic complexity of these systems impedes the quantitative understanding of QPTs. We observed and thoroughly analyzed the rich strongly correlated physics in two profoundly dissimilar regimes of quantum criticality. With a circuit implementing a quantum simulator for the three-channel Kondo model, we reveal the universal scalings toward different low-temperature fixed points and along the multiple crossovers from quantum criticality. An unanticipated violation of the maximum conductance for ballistic free electrons is uncovered. The present charge pseudospin implementation of a Kondo impurity opens access to a broad variety of strongly correlated phenomena.

Abstract
Red or processed meat rich diets have been shown to be associated with an elevated risk of colorectal cancer (CRC). One major hypothesis involves dietary heme iron which induces lipid peroxidation. The quantification of the resulting reactive aldehydes (e.g. HNE and HHE) in the colon lumen is therefore of great concern since these compounds are known for their cytotoxic and genotoxic properties. UHPLC-ESI-MS/MS method has been developed and validated for HNE and HHE quantification in rat faeces. Samples were derivatised using a brominated reagent (BBHA) in presence of pre-synthesized deuterated internal standards (HNE-d11/HHE-d5), extracted by solid phase extraction, and then analysed by LC-positive ESI-MS/MS (MRM) on a TSQ Vantage mass spectrometer. The use of BBHA allowed the efficient stabilisation of the unstable and reactive hydroxy-alkenals HNE and HHE. The MRM method allowed selective detection of HNE and HHE on the basis of characteristic transitions monitored from both the 79 and 81 bromine isotopic peaks. This method was validated according to the European Medicines Agency (EMEA) guidelines, by determining selectivity, sensitivity, linearity, carry-over effect, recovery, matrix effect, repeatability, trueness and intermediate precision. The performance of the method enabled the quantification of HNE and HHE in concentrations 0.10-0.15 μM in faecal water. Results are presented on the application to the quantification of HNE and HHE in different faecal waters obtained from faeces of rats fed diets with various fatty acid compositions thus corresponding to different pro-oxidative features.

Abstract
BACKGROUND Pheochromocytoma (PHEO) in pregnancy is a life-threatening condition. Its management is challenging with regards to the timing and type of surgery. METHODS A retrospective review of the management of ten patients diagnosed with pheochromocytoma during pregnancy was performed. Data were collected on the initial diagnostic workup, symptoms, treatment, and follow-up. RESULTS PHEO was diagnosed in ten patients who were between the 10th and the 29th weeks of pregnancy. Six patients had none to mild symptoms, while four had complications of paroxysmal hypertension. Imaging investigations consisted of MRI, CT scan and ultrasounds. All had urinary metanephrines, measured as part of their workup. Three patients had MEN 2A, one VHL syndrome, one suspected SDH mutation. All patients were treated either with α/β blockers or calcium channel blockers to stabilize their clinical conditions. Seven patients underwent a laparoscopic adrenalectomy before delivery. Three out of these seven patients had a bilateral PHEO and underwent a unilateral adrenalectomy of the larger tumor during pregnancy, followed by a planned cesarean section and a subsequent contralateral adrenalectomy within a few months after delivery. Three patients had emergency surgery for maternal or fetal complications, with C-section followed by concomitant or delayed adrenalectomy. All newborns from the group of planned surgery were healthy, while two out three newborns within the emergency surgery group died shortly after delivery secondary to cardiac and pulmonary complications. CONCLUSIONS PHEO in pregnancy is a rare condition. Maternal and fetal prognosis improved over the last decades, but still lethal consequences may be present if misdiagnosed or mistreated. A thorough multidisciplinary team approach should be tailored on an individual basis to better manage the pathology. Unilateral adrenalectomy in a pregnant patient with bilateral PHEO may be an option to avoid the risk of adrenal insufficiency after bilateral adrenalectomy.

Abstract
BACKGROUND An overview of labor based only on epidemiological data cannot identify or explain the mechanisms involved in childbirth. Data about the position that women should take in giving birth are discordant. None of the studies of birth positions adequately define or describe them or their biomechanical impact (pelvic orientation, position of the back). The measurement of the effect of one position relative to that of another requires precise definitions of each position and of their maternal biomechanical consequences, as well as safe measurement methods. METHODOLOGY We have developed a system to analyze the position of labor by quantifying the posture of the woman's body parts (including thighs, trunk, and pelvis), using an optoelectronic motion capture device (Vicon™, Oxford Metrics) widely used in human movement analysis and a system for measuring the lumbar curve (Epionics spine system). A specific body model has also been created to conduct this biomechanical analysis, which is based on external markers. With this methodology and model, it should be possible to define: (1) the hip joint angles (flexion/extension, abduction/adduction, internal/external rotation); (2) the ante/retroversion of the pelvis; (3) the lumbar curve. DISCUSSION This methodology could become a reference for assessing delivery postures, one that makes it possible to describe the relation between the postures used in the delivery room and their impact on the pelvis and the spine in an integrated and comprehensive model.

Abstract
OBJECTIVE To assess the frequency of labor and birth positions in 2015, and identify factors associated with choosing and changing position during labor. METHODS Multicenter prospective study during five weeks in 2015. We collected the distribution of the observed positions during the first and second stage of labor. Then we considered the main birth position as the one used for the longest duration. Factors associated to the main birth position as well as to the changes of position during labor were studied using univariate analysis and the role of each factor was analyzed using multilevel logistic regression. RESULTS Among women who delivered, 86.1% did so in gynecological position. There was a center effect for the position during the expulsive phase, which was not related to legal status or level of perinatal care. After adjustment, a labor duration shorter than 2hours was associated to dorsal decubitus during labor (OR=2.1 95%CI [1.01-4.3]). Prematurity and labor duration less than 2hours decreased the occurrence of changes in position during labor: OR=0.05 95%CI [0.01-0.2] and OR=0.2 95%CI [0.1-0.3]. Epidural analgesia was associated to change in birth position during labor: (OR=2.1 95%CI [1.2-3.8]). During the expulsive phase, primiparity and labor duration less than 2hours were associated to dorsal decubitus position (OR=3.6 95%CI [1.2-10.8]). CONCLUSION Women still mostly deliver in gynecological position in 2015. A systematic collection of birth positions on the partograph, with an acute definition of these positions, could allow an evaluation of the benefits/disadvantages of the different positions currently available.

Abstract
In 1909, Millikan showed that the charge of electrically isolated systems is quantized in units of the elementary electron charge e. Today, the persistence of charge quantization in small, weakly connected conductors allows for circuits in which single electrons are manipulated, with applications in, for example, metrology, detectors and thermometry. However, as the connection strength is increased, the discreteness of charge is progressively reduced by quantum fluctuations. Here we report the full quantum control and characterization of charge quantization. By using semiconductor-based tunable elemental conduction channels to connect a micrometre-scale metallic island to a circuit, we explore the complete evolution of charge quantization while scanning the entire range of connection strengths, from a very weak (tunnel) to a perfect (ballistic) contact. We observe, when approaching the ballistic limit, that charge quantization is destroyed by quantum fluctuations, and scales as the square root of the residual probability for an electron to be reflected across the quantum channel; this scaling also applies beyond the different regimes of connection strength currently accessible to theory. At increased temperatures, the thermal fluctuations result in an exponential suppression of charge quantization and in a universal square-root scaling, valid for all connection strengths, in agreement with expectations. Besides being pertinent for the improvement of single-electron circuits and their applications, and for the metal-semiconductor hybrids relevant to topological quantum computing, knowledge of the quantum laws of electricity will be essential for the quantum engineering of future nanoelectronic devices.

Abstract
OBJECTIVE In multidisciplinary prenatal diagnosis centers, the search for a tetrasomy 12p mosaic is requested following the discovery of a diaphragmatic hernia in the antenatal period. Thus, the series of Pallister Killian syndromes (PKS: OMIM 601803) probably overestimate the prevalence of diaphragmatic hernia in this syndrome to the detriment of other morphological abnormalities. METHODS A multicenter retrospective study was conducted with search for assistance from members of the French society for Fetal Pathology. For each identified case, we collected all antenatal and postnatal data. Antenatal data were compared with data from the clinicopathological examination to assess the adequacy of sonographic signs of PKS. A review of the literature on antenatal morphological anomalies in case of PKS completed the study. RESULTS Ten cases were referred to us: 7 had cytogenetic confirmation and 6 had ultrasound screening. In the prenatal as well as post mortem period, the most common sign is facial dysmorphism (5 cases/6). A malformation of limbs is reported in half of the cases (3 out of 6). Ultrasound examination detected craniofacial dysmorphism in 5 cases out of 6. We found 1 case of left diaphragmatic hernia. Our results are in agreement with the malformation spectrum described in the literature. CONCLUSION Some malformation associations could evoke a SPK without classical diaphragmatic hernia.

Abstract
Pre-eclampsia complicated by severe HELLP (hemolysis, elevated liver enzymes and low platelet count) syndrome is a multi-organ disease, and can be difficult to differentiate from thrombotic microangiopathy (appearing as thrombotic thrombocytopenic purpura or hemolytic uremic syndrome), acute fatty liver, systemic erythematous lupus, antiphospholipid syndrome and severe sepsis. Many papers have highlighted the risks of misdiagnosis resulting in severe consequences for maternal health, and this can be fatal when thrombotic thrombocytopenic purpura is misdiagnosed as severe HELLP syndrome. The aim of this paper is to propose relevant markers to differentiate pre-eclampsia complicated by severe HELLP syndrome from its imitators, even in the worrying situation of apparently indistinguishable conditions, and thereby assist clinical decision-making regarding whether or not to commence plasma exchange. Relevant identifiers to establish the most accurate diagnosis include the frequency of each disease and anamnestic data. Frank hemolysis, need for dialysis, neurological involvement and absence of disseminated intravascular coagulation are indicative of thrombotic microangiopathy. The definitive marker for thrombotic thrombocytopenic purpura is undetectable ADAMTS 13 activity.

Abstract
Three cases of ketosis decompensation occurring immediately in type I diabetic after corticotherapy for lung foetal maturation (LFM) are reported. Few of observations have been published. Increasing doses of insulin is mandatory under close monitoring of blood glucose levels, in particular according to the protocol proposed by Kaushal et al.: infusion of insulin adapted to the results of glucose levels, as a supplementation to the usual doses in each patient. Diabetes does not lead to hesitate prescribing a corticotherapy for LFM, but requires a strict control of needs in insulin to avoid a ketosis decompensation.

Abstract
It is widely admitted that neonates' platelet counts (PCs) are always normal in babies born to mothers with incidental gestational thrombocytopaenia. However, results of PC determinations at delivery have led us to wonder whether incidental gestational thrombocytopaenia is actually safe for the neonate under all circumstances, and to recommend that for every baby born to a mother with a pregnancy-associated thrombocytopaenia, even in the case of confirmed IGT, platelet counts on umbilical cord blood be closely monitored.
