RESUMO
The majority of psychoanalysts today admit that the body and the mind are not separate, but are on the contrary deeply intertwined with each other. Thus, it is possible to consider the psychic life as stemming from the vital necessity to process sensory information. Based on the recent discoveries of embryology, it becomes possible to rethink the consequences of the first inscriptions in the construction of the psyche, in connection with sensory experiences. This new knowledge makes it necessary to revise the metapsychology, making the first impulse appear as "tact-pulsion".

OBJECTIVES: Cancer during pregnancy affects 1 in 1000 pregnancies. This situation requires multidisciplinary team, however there is no care pathway dedicated to these patients. The main objective was to describe oncological, obstetrical, and neonatal care through a regional inventory. Our secondary objective was to define a regional "cancer and pregnancy" care pathway. MATERIAL AND METHOD: We carried out an observational, retrospective study from 2013 to 2019 including 48 women (all cancer types) from 2013 to 2019 in Occitania. Then, we defined an "optimal care pathway" and we assessed whether it was respected in the breast cancer subgroup of our cohort. RESULTS: Live births occurred in 79% of the women included. Maternal treatment was initiated during pregnancy for 67% of our population (44% chemotherapy). The most frequent pregnancy complication was preterm delivery (39%), mainly iatrogenic (86.6%). No patient in the group of breast cancer benefited from all of the ten criteria of the "optimal care pathway" that we proposed. CONCLUSIONS: A coordinated regional care pathway seems necessary to optimize communication between the healthcare providers (oncologists, gynecologists and multidisciplinary prenatal diagnosis centers, pharmacologists, pediatricians, psychologists, and general practitioners). This study identifies weaknesses in the management of women with cancer during pregnancy and suggests regional improvement opportunities.

Antenatal ear examination is an integral part of the thorough examination of the fetal face. The discovery of an anomaly, whether it is made by chance or during a complementary in-depth examination, leads the practitioner to determine its isolated or associated character, in order to characterise its possible belonging to a syndromic entity. In this context, the realization of genetic analysis more precise and wider allowing a return of the results in a time compatible with an evolutive pregnancy, gives to the geneticist a central role in the management of these couples. The main challenge lies in obtaining a set of concordant clinical and biological clues, enabling the genetic results identified to be interpreted correctly, the optimised functioning of the ultrasound practitioner - geneticist duo is therefore fundamental. This results in a complex information to deliver, in the fact that the clinical translation of an ear anomaly in antenatal can go from an isolated aesthetic anomaly to a genetic syndrome with neurodevelopmental disorder. The objective of this work is to describe, from a methodological analysis of antenatal ears, the accessible malformative entities, isolated or associated, and to discuss the problems in the need or not to propose their screening.

Denial of pregnancy is a public health problem due to maternal, fetal, and neonatal morbidity, affecting both physical and mental health. It generally involves an absence of the physical signals associated with pregnancy such as abdominal swelling, amenorrhea, weight gain, or even perception of fetal movements. Despite the potential consequences for mother and child, there is still little data on its clinical features and the neurocognitive mechanisms involved. In this paper, we provide an update on the clinical, socio-demographic, and psychopathological characteristics of pregnancy denial based on contemporary scientific literature. We first define denial of pregnancy by referring to the history of the concept, previous definitions, and nosographic classifications. We then detail the clinic of denial by distinguishing the physical and psychological symptoms of this disorder, then the socio-demographic, gynecological, and psychiatric characteristics. We describe the consequences of denial on the mother, infant, and the dyad, referring to situations of cryptic neonaticide. Finally, we show the importance of perinatal neuroscience research on maternal interoception to understand the mechanisms involved in denial of pregnancy, and improve their medical management in clinical practice.

Facial cleft are the most frequent craniofacial anomalies with an incidence of one for 1000 births, all births combined, and require specialized multidisciplinary care. Since 2005, the systematic realization of two ultrasound views (nose-lip and profile) is recommended for the exploration of the fetal face in the 2nd trimester of pregnancy. Application of these recommendations should allow screening of the majority of cleft lip and palate. However, cleft palates, without labiomaxillary involvement, are currently largely underdiagnosed at prenatal ultrasound, although they can be associated with a syndromic diagnosis in up to 30% of cases. The aim of this work is to describe, from embryology to surgical consultation, the complete ultrasound examination of a fetus with a classic facial cleft.

We aimed to investigate tendon variations of the extensor digitorum (ED), extensor digiti minimi (EDM), and extensor indicis proprius (EIP) muscles. Our study was performed on 43 fetal cadavers (86 extremities), aged between 17 and 40 weeks of gestation. The number of ED tendons varied from three to six, proximal to the extensor retinaculum (ER), and from three to eight, distal to the ER. The ED most often had four tendons, both proximally and distally from the ER. The ED tendons of the fourth finger were observed to be most frequently duplicated. The most common juncturae tendinum (JT) was type 1 in the second intermetacarpal space (IMCS), type 2 in the third IMCS, and type 3r in the fourth IMCS according to von Schroeder classification. The number of EIP and EDM tendons varied from one to two and from one to five, respectively. The EIP double tendons inserted both into the ulnar and palmar sides of the extensor digitorum of the second finger, which had not been reported in the literature. In our study, 7% of hands had variant muscles. In 4.7% of hands, the extensor indicis et medii communis was observed, while the extensor medii proprius and the extensor digitorum brevis manus were observed in 1.2% and 1.2% of hands, respectively. Knowing the prevalence of the ED, EDM and EIP tendons and their variations in the fetal period should help to treat partial loss of hand function or injury after birth and to correct congenital hand deformities.

OBJECTIVES: Skeletal remains of pregnant woman whit fetus still in the pelvic region are scarce in the archaeological record. We aimed to review the different cases of maternal and fetal death in the ancient times. METHODS: A review of literature using Medline database and Google about mortality during pregnancy in Prehistory, Antiquity and middle age. The following key words were used: ancient times; paleopathology; immature fetus; medieval; pregnancy; mummies; Antiquity; maternal mortality. RESULTS: Thirty articles were found and we added one personal unpublished case. There were 64 female skeletons with mainly infectious abnormalities (10 dental abscesses and 2 pneumoniae) followed by traumatic lesions (2 frontal fractures and 1 femur luxation). There were 48 fetal remains and 3 twins. We noted 8 obstructed labors (3 breech presentations, 4 transverse lies and one possible shoulder dystocia). CONCLUSIONS: The fact that there were only few cases of maternal deaths with fetal remains raises the questions of the cause of death and the relationship between death and obstetric disorders. Beside the underestimation of these archaecological cases, the reasons of both fetal and maternal death must be looking for among several diseases or anomalies of both or of one of them, related with poor environmental conditions (such as malnutrition and high morbidity from infections) and lack of care the mother and fetus need.

OBJECTIVE: To investigate prenatal diagnosis characteristics and pregnancy outcomes associated with isolated right aortic arch (RAA). METHODS: A retrospective study including fetuses with isolated RAA, managed between January 2010 and February 2018. Cases were identified from the ultrasound databases of the expert pediatric cardiologists, who made the aforementioned diagnosis. All fetuses were examined by a fetal medicine imaging expert to exclude any extracardiac abnormality. A systematic review was performed to assess the prenatal diagnosis and outcomes of fetuses with isolated RAA. RESULTS: Fifty-six fetuses were diagnosed with an isolated RAA. An isolated double aortic arch (DAA) was diagnosed in one fetus. Mean gestational age at diagnosis was 24 weeks. The sex ratio (boy/girl) was 0.89. No significant abnormality was detected in invasive tests (karyotype and FISH or microarray). Only one fetus was misdiagnosed with isolated RAA. He was the only symptomatic (stridor) newborn baby and was later diagnosed with DAA. Four studies were included in our systematic review representing 115 cases of isolated RAA. One significant chromosomal abnormality was detected: a 22q11 deletion in a newborn baby who had a postnatal finding of a soft palate cleft. There was one major obstetric complication: an intrauterine fetal demise at 41 gestational weeks. CONCLUSION: Diagnosis of isolated RAA can be challenging. Invasive tests are to be discussed. The diagnosis of isolated RAA should not change obstetric monitoring. Nevertheless, an echocardiography should be performed systematically in these new newborn babies within their first month of life.

Prenatal ethanol (EtOH) exposure is known to induce adverse effects on fetal brain development. Docosahexaenoic acid (DHA) has been shown to alleviate these effects by up-regulating antioxidant mechanisms in the brain. The liver is the first organ to receive enriched blood after placental transport. Therefore, it could be negatively affected by EtOH, but no studies have assessed the effects of DHA on fetal liver. This study examined the effects of maternal DHA intake on DHA status and gene expression of key enzymes of the glutathione antioxidant system in the fetal liver after prenatal EtOH exposure. Pregnant Sprague-Dawley dams were intubated with EtOH for the first 10 days of pregnancy, while being fed a control or DHA-supplemented diet. Fetal livers were collected at gestational day 20, and free fatty acids and phospholipid profile, as well as glutathione reductase (GR) and glutathione peroxidase-1 (GPx1) gene expressions, were assessed. Prenatal EtOH exposure increased fetal liver weight, whereas maternal DHA supplementation decreased fetal liver weight. DHA supplementation increased fetal liver free fatty acid and phospholipid DHA independently of EtOH. GR and GPx1 messenger RNA (mRNA) expressions were significantly increased and decreased, respectively, in the EtOH-exposed group compared with all other groups. Providing DHA normalized GR and GPx1 mRNA expression to control levels. This study shows that maternal DHA supplementation alters the expression of fetal liver genes involved in the glutathione antioxidative system during prenatal EtOH exposure. The fetal liver may play an important role in mitigating the signs and symptoms of fetal alcohol spectrum disorders in affected offspring.

OBJECTIVE: We sought to evaluate whether the antenatal identification of small for gestational age (SGA) fetuses could influence the neonatal and obstetric prognosis. METHODS: This was a retrospective cohort study. All liveborn singleton neonates with a birthweight<3rd centile, born>32 weeks of gestation between January 1, 2011 and December 31, 2012 were included. Fetuses were considered "suspected SGA" when the estimated fetal weight was<10th centile or when a diagnosis of clinical or ultrasound SGA was explicitly noted in the record. Obstetrical and neonatal follow-up and outcomes of suspected SGA (SGAS group) and non-suspected (SGANS group) were compared, with Chi2 and the Fisher exact test when appropriate. RESULTS: Hundred and forty-seven neonates were included. Among these, 54% were suspected SGA before birth. Gestational age was lower (38.5 weeks gestation [WG] vs. 39.6 WG, P<0.001) and there was a higher preterm birth rate in the SGAS group (10% vs. 0%, P=0.005). The rate of elective cesarean sections (17% vs. 3%, P=0.005) was higher in the SGAS group, whereas the rate of nonelective cesarean sections was lower (20% vs. 33%, P=0.002). Neonatal morbidity was similar in both groups, as well as birth weight. CONCLUSION: SGA fetal screening in our cohort was associated with a higher rate of medical intervention and preterm birth without neonatal benefit. Nevertheless, the study's power and methodology are not adequate to reduce the risk of fetal death in utero or severe asphyxia associated with non-identification of a SGA fetus.

Adequate thiamin levels are crucial for optimal health through maintenance of homeostasis and viability of metabolic enzymes, which require thiamine as a co-factor. Thiamin deficiency occurs during pregnancy when the dietary intake is inadequate or excessive alcohol is consumed. Thiamin deficiency leads to brain dysfunction because thiamin is involved in the synthesis of myelin and neurotransmitters (e.g., acetylcholine, γ-aminobutyric acid, glutamate), and its deficiency increases oxidative stress by decreasing the production of reducing agents. Thiamin deficiency also leads to neural membrane dysfunction, because thiamin is a structural component of mitochondrial and synaptosomal membranes. Similarly, in-utero exposure to alcohol leads to fetal brain dysfunction, resulting in negative effects such as fetal alcohol spectrum disorder (FASD). Thiamin deficiency and prenatal exposure to alcohol could act synergistically to produce negative effects on fetal development; however, this area of research is currently under-studied. This minireview summarizes the evidence for the potential role of thiamin deficiency in fetal brain development, with or without prenatal exposure to alcohol. Such evidence may influence the development of new nutritional strategies for preventing or mitigating the symptoms of FASD.

Pregnancy is a period of psychological change which may lead to difficulties of adaptation and psychological suffering and give rise to high-risk behaviours for the fÅtus in pregnant women. These risk behaviours, which are defined by certain authors as a form of "maltreatment" of the fÅtus, usually spring from the psychological distress of the pregnant woman but are not recognised as a specific medical disorder. We illustrate the difficulties encountered in the identification of, and the specific intervention in, these situations through the clinical case of a pregnant drugs-dependent patient subjected to several stress factors who, in addition to consuming substances, developed high-risk behaviours for herself and her pregnancy: self-endangerment under the influence of substances, falls or refusals of treatment. In our first part, we discuss the medicolegal possibilities afforded by French law to protect the fÅtus in the event of the future mother's high-risk behaviours. In our second part, we discuss the successive evolutions of the legal status of the fÅtus and pregnancy, and their consequences for medical practice and the clinical situations concerned. The lack of an answer concerning the designation of these behaviours, as either medical, legal or social acts, will prompt perinatal practitioners to a certain medicolegal prudence.

Early malnutrition is a risk factor for depression and schizophrenia. Since the offspring of malnourished dams exhibit increased brain levels of serotonin (5-HT), a tryptophan-derived neurotransmitter involved in the pathophysiology of these mental disorders, it is believed that the deleterious effects of early malnutrition on brain function are due in large part to altered serotoninergic neurotransmission resulting from impaired tryptophan (Trp) metabolism. However, tryptophan is also metabolized through the kynurenine (KYN) pathway yielding several neuroactive compounds including kynurenic (KA), quinolinic (QA) and xanthurenic (XA) acids. Nevertheless, the impact of perinatal malnutrition on brain kynurenine pathway metabolism has not been examined to date. Here, we used ultra-performance liquid chromatography-tandem mass spectrometry for the simultaneous quantification of tryptophan and a set of seven compounds spanning its metabolism through the serotonin and kynurenine pathways, in the brain of embryos and adult offspring of rat dams fed a protein-restricted (PR) diet. Protein-restricted embryos showed reduced brain levels of Trp, serotonin and KA, but not of KYN, XA, or QA. In contrast, PR adult rats exhibited enhanced levels of Trp in the brainstem and cortex along with increased concentrations of 5-HT, kynurenine and XA. The levels of XA and KA were also increased in the hippocampus of adult PR rats. These results show that early protein deficiency induces selective and long-lasting changes in brain kynurenine metabolism. Given the regulatory role of KYN pathway metabolites on brain development and function, these changes might contribute to the risk of developing psychiatric disorders induced by early malnutrition.

Congenital skin aplasia, or aplasia cutis congenita (ACC) is a rare congenital disease. It is characterized by the absence of skin at birth, localized or widespread, of one or several areas. This condition commonly involve the scalp but can also involve more rarely the trunk or limbs. However it is most frequently an isolated disorder, it can be associated with other anomalies, such as the Adams-Oliver syndrome, the association with a fetus papyraceus or with an epidermolysis bullosa. Many hypothesis have been suggested: vascular, genetic, traumatic, pharmacological or an anomaly in the neural tube closure process, but the exact mechanism is still unknown. Morbidity and mortality of this malformation depends on the affected area and the size of the defect. The main risk is the infection, hemorrhage and thrombosis in the case of a scalp defect with an underlying bone defect, the exposure of the meninges and the superior sagittal sinus. The initial management of ACC will therefore involve several plastic surgery techniques, from more simple to more complex, using conservative wound care to flaps techniques. Other techniques can be performed later, in the management of ACC sequelae, such as skin expansion for scarring alopecia.

The diagnostic of cancer during pregnancy is a rare and delicate situation. As the developments of the embryo and the human fetus are extremely sensitive to ionizing radiations, the treatment of these tumors should be discussed. The studies - preclinical and clinical - based mostly on exposure accidents show that subdiaphragmatic treatments are possible during pregnancy. When radiotherapy is used, phantom estimations of the dose to the fetus, confirmed by in vivo measurements are required. Irradiation and imaging techniques should be arranged to decrease as much as possible the dose delivered to the fetus and hold below the threshold of 0.1Gy.

OBJECTIVES: Fetus small for gestational age (SGA) screening rate is evaluated around 21,7 % in France. Recommendations were developed to improve the efficiency of ultrasound conducted in the third trimester (T3), because neonatal consequences can be significant. This study aims to evaluate screening of SGA during T3 ultrasound and to describe causes for failure and differences with the recommendations of CNGOF. METHODS: All children born between 2011 and 2012 with a birth weight below the 3rd percentile were included in this observational, retrospective, monocentric study. We noted that the diagnosis of SGA was placed on file. Then, as recommended by the CNGOF, we calculated estimated fetal weight (EFW) with Hadlock 3 and Hadlock 4, and the corresponding percentiles, using the biometrics from the ultrasound report. We thus could evaluate a new screening rate with SGA fetus identified through this technique. RESULTS: A total of 142 patients were included. By calculating correctly all EFW and checking abdominal circumference percentiles, the screening rate of SGA fetuses with T3 ultrasound increased from 40 % to 50 % and the overall screening rate (clinical and ultrasound) from 54 % to 66 %. CONCLUSION: By following the recommendations we found a real improvement in fetal SGA screening rates to T3 ultrasound with a potential benefit for their care.

We report 4 cases of Harlequin ichthyosis, which is a rare and severe congenital ichthyosis involving the face. Facial appearance consists in severe ectropion, conjonctival edema, eclabium, flattened ears, broadened nose and large, thick, plate-like skin scales. Recent advances in neonatal care have been made, such as retinoid therapy, and have led to an increased survival rate. Early surgical correction of ectropion may be required because of ocular complications.

Masculinisation and adult fertility in the male are dependent on appropriate fetal endocrine programming. There is also now increasing evidence to indicate that the same mechanisms which regulate masculinisation also affect the general wellbeing of males throughout their life and, particularly, during ageing. Testosterone, secreted by the fetal testes, is the main factor regulating these processes and an understanding of fetal testis development in the human male is essential if we are to prevent adult reproductive disorders. This review focuses on what is known about human testis development and describes the effects of maternal smoking, a surrogate of possible xenotoxicant exposure on fetal testis and fetal liver function.
