Amelioration potential of Moringa oleifera extracts against sodium arsenate induced embryotoxicity and genotoxicity in mouse (Mus musculus) / Potencial de melhoria de extratos de Moringa oleifera contra embriotoxicidade e genotoxicidade induzida por arseniato de sódio em camundongos (Mus musculus)

Previous studies have suggested that arsenic crosses the placenta and affects the fetus development. The study under consideration aims to show comparative ameliorative effect of Moringa oleifera leaf and flower extracts against sodium arsenate induced fetus toxicity of mice. Pregnant mice (N=44) were kept in lab and divided into eleven group from (A to K) and were orally administered the doses 6 mg/kg, 12 mg/kg for sodium arsenate, 150 mg/kg and 300 mg/kg for Moringa oleifera leaf extracts (MOLE) and 150 mg/kg and 300 mg/kg for Moringa oleifera flower extracts (MOFE) comparing with control. The investigation revealed evident reduction in the fetuses weight, hind limb, fore limb, tail and snout length, crown rump and head circumferences well as malformations in tail, feet, arms, legs, skin and eyes in the negative control group (only administered with sodium arsenate). Co-administration of sodium arsenate with MOLE and MOFE ameliorate the reversed effect of sodium arsenate on the shape, length, body weight and DNA damage of fetus significantly at 95% confidence interval. However, Moringa oleifera leaf extract showed more significant results in comparison to Moringa oleifera flower extract. Hence concluded that Moringa oleifera leaf extract ameliorated the embryo toxic effects of sodium arsenate and can be used against environmental teratogens.

Estudos anteriores sugeriram que o arsênio atravessa a placenta e afeta o desenvolvimento do feto. O estudo em consideração visa mostrar o efeito melhorador comparativo de extratos de folhas e flores de Moringa oleifera contra a toxicidade fetal induzida por arseniato de sódio em camundongos. Camundongos grávidas (N = 44) foram mantidos em laboratório e divididos em 11 grupos (de A a K) e foram administrados por via oral nas doses de 6 mg/kg, 12 mg/kg para arseniato de sódio, 150 mg/kg e 300 mg/kg para extratos de folhas de Moringa oleifera (MOLE) e 150 mg/kg e 300 mg/kg para extratos de flores de Moringa oleifera (MOFE) em comparação com o controle. A investigação revelou redução evidente no peso do feto, membro posterior, membro anterior, comprimento da cauda e focinho, coroa, nádega e circunferência da cabeça, bem como malformações na cauda, pés, braços, pernas, pele e olhos no grupo de controle negativo (apenas administrado com arseniato de sódio). A coadministração de arseniato de sódio com MOLE e MOFE melhora significativamente o efeito reverso do arseniato de sódio na forma, comprimento, peso corporal e dano ao DNA do feto, com intervalo de confiança de 95%. No entanto, o extrato da folha da Moringa oleifera apresentou resultados mais significativos em comparação ao extrato da flor da Moringa oleifera. Portanto, concluiu que o extrato da folha de Moringa oleifera melhorou os efeitos tóxicos do arseniato de sódio para o embrião e pode ser usado contra teratógenos ambientais.

Percepção sobre o cuidado à perda gestacional: estudo qualitativo com casais brasileiros / Perceptions on pregnancy loss care: a qualitative study with brazilian couples / Percepción sobre la atención a la pérdida del embarazo: estudio cualitativo con parejas brasileñas

Este artigo analisou a percepção e os sentimentos de casais sobre o atendimento recebido nos serviços de saúde acessados em função de perda gestacional (óbito fetal ante e intraparto). O convite para a pesquisa foi divulgado em mídias sociais (Instagram e Facebook). Dos 66 casais que contataram a equipe, 12 participaram do estudo, cuja coleta de dados ocorreu em 2018. Os casais responderam conjuntamente a uma ficha de dados sociodemográficos e uma entrevista semiestruturada, realizada presencialmente (n=4) ou por videochamada (n=8). Os dados foram gravados em áudio e posteriormente transcritos. A Análise Temática indutiva das entrevistas identificou cinco temas: sentimento de impotência, iatrogenia vivida nos serviços, falta de cuidado em saúde mental, não reconhecimento da perda como evento com consequências emocionais negativas, e características do bom atendimento. Os achados demonstraram situações de violência, comunicação deficitária, desvalorização das perdas precoces, falta de suporte para contato com o bebê falecido e rotinas pouco humanizadas, especialmente durante a internação após a perda. Para aprimorar a assistência às famílias enlutadas, sugere-se qualificação profissional, ampliação da visibilidade do tema entre diferentes atores e reorganização dos serviços, considerando uma diretriz clínica para atenção ao luto perinatal, com destaque para o fortalecimento da inserção de equipes de saúde mental no contexto hospitalar.(AU)

This study analyzed couples' perceptions and feelings about pregnancy loss care (ante and intrapartum fetal death). A research invitation was published on social media (Instagram and Facebook) and data collection took place in 2018. Of the 66 couples who contacted the research team, 12 participated in the study by filling a sociodemographic questionnaire and answering a semi-structured interview in person (n=04) or by video call (n=08). All interviews were audio recorded, transcribed, and examined by Inductive Thematic Analysis, which identified five themes: feelings of impotence, iatrogenic experiences in health services, lack of mental health care, not recognizing pregnancy loss as an emotionally overwhelming event, and aspects of good healthcare. Analysis showed experiences of violence, poor communication, devaluation of early losses, lack of support for contact with the deceased baby, and dehumanizing routines, especially during hospitalization after loss. Professional qualification, extended pregnancy loss visibility among different stakeholders, and reorganization of health services are needed to improve the care offered to grieving families, considering a clinical guideline for perinatal grief care with emphasis on strengthening the insertion of mental health teams in the hospital context.(AU)

Early pregnancy exposure to beta-cypermethrin compromises endometrial decidualisation in mice via downregulation of cyclin D3, CDK4/6, and p21.

Beta-cypermethrin (ß-CYP) is a highly effective broad-spectrum insecticide that can potentially affect female reproduction. However, little is known about the effect of ß-CYP on uterine decidualisation, which is a vital process by which the uterus provides a suitable microenvironment for pregnancy maintenance. Therefore, we focused on the effect and mechanism of ß-CYP on endometrial decidualisation during early pregnancy in mice. The results indicated that the expression levels of HOXA10, BMP2, and IGFBP1 was significantly downregulated in the decidual tissue and primary endometrial stromal cells of pregnant and pseudopregnant mice following ß-CYP treatment. Serum E2 concentration was significantly increased, whereas P4 concentration and oestrogen receptor (ERα) and progesterone receptor (PRA) expression were significantly downregulated following ß-CYP exposure. The number of polyploid decidual cells was lower in the ß-CYP-treated group. Furthermore, ß-CYP significantly downregulated the protein expression levels of CDK4 and CDK6, and the mRNA expression levels of cyclin D3 and p21. The number of foetuses per female in the first litter was markedly reduced following exposure to ß-CYP. In summary, early pregnancy exposure to ß-CYP may result in defective endometrial decidualisation via compromised proliferation of uterine stromal cells and reduced expressions of cyclin D3, CDK4/6, and p21 in mice.

Fetal proximal and distal limb anomalies following exposure to mycophenolate mofetil during pregnancy: A case report and review of the literature.

BACKGROUND: Mycophenolate mofetil (MMF) is currently used in a wide spectrum of autoimmune diseases and has been rendered very effective in the management of systemic lupus erythematosus and lupus nephritis. MMF is known to be teratogenic (FDA category D) and therefore, women in childbearing period receiving MMF should be counselled to use effective contraceptive methods to avoid an unplanned pregnancy. CASE: A 22-year-old lady accidentally discovered to be pregnant while using MMF as a treatment of lupus nephritis which was replaced later on by azathioprine. After maternal and fetal evaluation, maternal lupus flare was confirmed and multiple fetal skeletal deformities associated with intrauterine growth restriction (IUGR) were diagnosed by 4-dimensional ultrasound. Termination of pregnancy was decided after shared decision making. CONCLUSION: Women in childbearing period should be advised to postpone pregnancy for at least six weeks after stoppage of MMF therapy because of its potential teratogenic effects during pregnancy.

Novel agents for the treatment of lymphomas during pregnancy: A comprehensive literature review.

Lymphoproliferative diseases occurring during pregnancy present unique diagnostic and therapeutic challenges aiming to achieve maternal cure without impairing fetal health, growth, and survival. These goals are further complicated by the fast-paced emergence of novel therapies and their introduction as standard of care, even in newly diagnosed patients. Due to the rarity of hematological malignancies in pregnancy and the exclusion of pregnancy in almost all clinical trials, available data on the fetal effects of novel drugs are limited to animal models and case reports. The current review addresses the entire multidisciplinary team involved in treating pregnant patients with lymphoproliferative diseases. We describe novel agents according to their mechanism of action, and summarize our knowledge of their effects during the gestational period, particularly those associated with fetotoxicity. Therapeutic dilemmas associated with the employment of these new agents are also discussed.

Immune dysfunction in developmental programming of type 2 diabetes mellitus.

Intrauterine growth restriction (IUGR) is a common complication of pregnancy and increases the risk of the offspring developing type 2 diabetes mellitus (T2DM) later in life. Alterations in the immune system are implicated in the pathogenesis of IUGR-induced T2DM. The development of the fetal immune system is a delicate balance as it must remain tolerant of maternal antigens whilst also preparing for the post-birth environment. In addition, the fetal immune system is susceptible to an altered intrauterine milieu caused by maternal and placental inflammatory mediators or secondary to nutrient and oxygen deprivation. Pancreatic-resident macrophages populate the pancreas during fetal development, and their phenotype is dynamic through the neonatal period. Furthermore, macrophages in the islets are instrumental in islet development as they influence ß-cell proliferation and islet neogenesis. In addition, cytokines, derived from ß-cells and macrophages, are important to islet homeostasis in the fetus and adult and, when perturbed, can cause islet dysfunction. Several activated immune pathways have been identified in the islets of people who experienced IUGR, with alternations in the levels of IL-1ß and IL-4 as well as changes in TGFß signalling. Leptin levels are also altered. Immunomodulation has shown therapeutic benefit in T2DM and might be particularly useful in IUGR-induced T2DM.

Benefit of antenatal corticosteroids by year of birth among preterm infants in Canada during 2003-2017: a population-based cohort study.

OBJECTIVE: To evaluate the changes in the associations of antenatal corticosteroids (ACS) with neonatal mortality and severe neurological injury over time (2003-17). DESIGN: National, population-representative, retrospective cohort study. SETTING: Level III neonatal intensive care units participating in the Canadian Neonatal Network. POPULATION: All infants born at 230/7 -336/7 weeks of gestation (n = 43 456). METHODS: We estimated the associations between exposure to ACS and neonatal outcomes by year of birth. Year of birth was considered both continuously and categorically as three consecutive epochs. MAIN OUTCOME MEASURE: Neonatal mortality and severe neurological injury. RESULTS: The absolute rates of neonatal mortality and severe neurological injury decreased during the study period in both the ACS and No ACS groups. For infants born at 230/7 -306/7 weeks of gestation, ACS was associated with similar reductions in neonatal mortality across the three epochs (9.0% versus 18.1%, adjusted relative risk [aRR] 0.54, 95% CI 0.47-0.61 in 2003-09; 7.6% versus 19.6%, aRR 0.51, 95% CI 0.44-0.59 in 2010-13; and 7.3% versus 14.5%, aRR 0.56, 95% CI 0.46-0.68 in 2014-17) and in severe neurological injury (13.2% versus 25.8%, aRR 0.57, 95% CI 0.50-0.64 in 2003-09; 7.4% versus 17.4%, aRR 0.53, 95% CI 0.43-0.66 in 2010-14; and 7.2% versus 14.8%, aRR 0.59, 95% CI 0.48-0.74 in 2014-17). CONCLUSION: Despite the ongoing improvements in neonatal care of preterm infants, as reflected by the gradual decrease in the absolute rates of neonatal mortality and severe neurological injury, the association of ACS treatment with neonatal mortality and severe neurological injury among extremely preterm infants born at 23-30 weeks of gestation has remained stable throughout the study period of 15 years. TWEETABLE ABSTRACT: Despite the gradual decrease in the rates of neonatal mortality and severe neurological injury, antenatal corticosteroids remain an important intervention in the current era of neonatal care.

Perinatal factors affecting platelet parameters in late preterm and term neonates.

Platelets parameters including platelet count (PLT), plateletcrit (PCT), mean platelet volume (MPV) and platelet distribution width (PDW) are associated with various physiological and pathological functions in various disease. However, few studies have addressed whether perinatal factors may be associated with platelet parameters at birth in a large cohort of late preterm and term neonates. The aim of this study to investigate perinatal factors affecting platelet parameters in late preterm and term neonates. We retrospectively investigated platelet parameters including PLT, PCT, MPV, and PDW on the first day of life in 142 late preterm and 258 term neonates admitted to our NICU from 2006 through 2020. PLT, MPV, PCT, PDW on Day 0 did not significantly differ between the two groups. In term neonates, multivariate analysis revealed that PCT correlated with being small for gestational age (SGA) (ß = -0.168, P = 0.006), pregnancy induced hypertension (PIH) (ß = -0.135, P = 0.026) and male sex (ß = -0.185, P = 0.002). PLT was associated with SGA (ß = -0.186, P = 0.002), PIH (ß = -0.137, P = 0.024) and male sex (ß = -0.166, P = 0.006). In late preterm neonates, multivariate analysis revealed that PLT were associated with PIH, whereas no factors associated with PDW and MPV were found. In all patients studied, chorioamnionitis (CAM) was significantly associated with MPV (CAM = 10.3 fL vs. no CAM = 9.7 fL, P<0.001). Multivariate analysis showed that SGA, male sex and PIH were associated with PCT and PLT. This study demonstrates that different maternal and neonatal complications affect platelet parameters in late preterm and term neonates.

Advances in scarless foetal wound healing and prospects for scar reduction in adults.

Healing after mammalian skin injury involves the interaction between numerous cellular constituents and regulatory factors, which together form three overlapping phases: an inflammatory response, a proliferation phase and a remodelling phase. Any slight variation in these three stages can substantially alter the healing process and resultant production of scars. Of particular significance are the mechanisms responsible for the scar-free phenomenon observed in the foetus. Uncovering such mechanisms would offer great expectations in the treatment of scars and therefore represents an important area of investigation. In this review, we provide a comprehensive summary of studies on injury-induced skin regeneration within the foetus. The information contained in these studies provides an opportunity for new insights into the treatment of clinical scars based on the cellular and molecular processes involved.

Concentrations of organochlorine pesticides in placental tissue are not associated with risk for fetal orofacial clefts.

Previous epidemiological studies have shown that prenatal exposure to organochlorine pesticides (OCPs) entails a variety of adverse impacts on fetal health, but it is not yet known whether it is associated with risk for orofacial clefts (OFCs). This study of 103 fetuses or newborns with a diagnosis of OFCs (cases) and 103 healthy newborns without malformations (controls) examined whether prenatal exposure to OCPs, as indicated by their concentrations in placental tissue, is a risk factor for OFCs. No differences were found in the median concentrations of OCPs between cases and controls, with exception of o,p'-dichlorodiphenyldichloroethylene, o,p'-dichlorodiphenyldichloroethane, and total o,p'-dichlorodiphenyltrichloroethane (DDTs), whose concentrations were higher in controls than in cases (Ps < 0.05). Although higher concentrations of placental δhexachlorocyclohexane and isodrin were found to be associated with decreased risk for OFCs in logistic regression, no association was observed in the Bayesian kernel machine regression, a novel statistical model in analyzing exposure mixtures. Women who reported periconceptional folic acid supplementation had lower placental concentrations of DDTs than women who did not. In conclusion, no association between levels of OCPs in placental tissue and risk for OFCs was observed in this population. Supplementation with folic acid may help decrease the levels of DDTs in placental tissue, but further studies are needed to confirm this unexpected finding.

Comparison of maternal and fetal complications in pregnant women with breech presentation undergoing spontaneous or induced vaginal delivery, or cesarean delivery.

OBJECTIVE: Breech presentation is the most common form of malpresentation, and associated with perinatal asphyxia and mortality, and maternal morbidity. Data associated with labor induction in breech presentation are limited. The aim of this study was to compare maternal and fetal complication rates in induced and spontaneous vaginal, and cesarean delivery with breech presentation. MATERIALS AND METHODS: Pregnant women with breech presentation were grouped: spontaneous vaginal delivery (Group 1, n = 72) induced or augmented vaginal delivery (Group 2, n = 32), and cesarean delivery (Group 3, n = 253). Fetal complications were as follows: clavicle fracture, femur fracture, humerus fracture, brachial plexus injury, cephalic hematoma, pneumothorax, need for intensive care unit (ICU), and 5th minute APGAR <7. Maternal complications were as follows: vaginal hematoma, deep vaginal laceration, perineal injury (≥3rd degree), decline in hemoglobin level (>2 g/dL), and postpartum endometritis. Data were collected and analyzed retrospectively. RESULTS: The highest fetal complication rate was in Group 2, and the lowest in Group 3 (p = 0.001). Clavicle fracture was significantly less in Group 3 compared with the other groups (p = 0.024). The rate of lower APGAR scores at the 5th minute was similar in all groups. Maternal complications were significantly higher in Group 2 compared with the other groups (p = 0.001). Fetal complications were 5.66-fold higher in Group 1 than in Group 3 (p = 0.002). Fetal and maternal complications were 9.48-fold and 7.48-fold higher, respectively, in Group 2 than in Group 3 (p < 0.001). CONCLUSION: This study is the first in literature to have investigated and analyzed neonatal complications in breech delivery according to different delivery modes including induced vaginal delivery. Due to possible complications, the risks and benefits of a specific type of delivery should be considered in breech presentation.

Management of Intracranial Hemorrhage and Skull Fracture After Blunt Intrauterine Trauma.

BACKGROUND: Fetal trauma during pregnancy can have a significant impact on the developing brain. Fetal trauma can lead to several intracranial pathologies including hypoxic-ischemic injury, skull fractures, and intracranial hemorrhages. Blunt trauma to a fetus resulting in the need for neurosurgical intervention is a rare occurrence and seldom described in the literature. CASE DESCRIPTION: Here we present the case of a 28-year-old, 36-week pregnant woman who was brought to the hospital by ambulance following a high-speed motor vehicle collision as the restrained driver. On computed tomography of the abdomen, the fetus was found to have a left-sided skull fracture with intracranial hemorrhage. The fetus was emergently delivered by way of caesarean section for lack of fetal movement and indeterminate heart tracings. Postnatally, the neonate had a Glasgow Coma Scale of 7. A postnatal head computed tomography better defined the skull fractures and multiple areas of intracranial hemorrhage. The baby was taken to the operating room for evacuation of the hematomas. At 16 months of age, the baby was well with only mild developmental delay, although a ventriculoperitoneal shunt was needed in a delayed fashion at 3 months of age. CONCLUSIONS: We present a rare situation where emergent caesarean section delivery followed by neonatal craniotomy was necessary. Our case illustrates that good outcomes can be achieved with rapid identification of fetal intracranial injury and intervention.

Implementation of a multidisciplinary perinatal emergency response team improves time to definitive obstetrical evaluation and fetal assessment.

BACKGROUND: Trauma is the leading cause of nonobstetric death during pregnancy and is associated with an increased risk of maternal and fetal mortality. In an effort to improve the delivery of care to pregnant trauma patients, we developed an institutional multidisciplinary quality initiative designed to improve response times of nontrauma specialists and ensure immediate availability of resources. We hypothesized that implementation of a perinatal emergency response team (PERT) would improve time to patient and fetal evaluation and monitoring by the obstetrics (OB) team and improve both maternal and fetal outcomes. METHODS: We performed a 6-year (2012-2018) retrospective cohort analysis of consecutive pregnant trauma patients presenting to our university-affiliated, level I trauma center. Patients in the pre-PERT cohort (before April 2015) were compared with a post-PERT cohort. Variables analyzed included patient demographics, mechanism of injury, Injury Severity Score, and level of trauma activation. The main outcome measure was time to OB evaluation. Secondary outcomes included time to cardiotocometry, and mortality. RESULTS: Of 92 pregnant trauma patients, there were 50 patients (54.3%) in the pre-PERT cohort and 42 (45.7%) in the post-PERT group. Blunt injuries predominated (98.9%), with the most common mechanism being motor vehicle collisions (76.1%), followed by assaults (13%) and falls (6.5%). The mean time to obstetrical evaluation was 44 minutes in the pre-PERT cohort compared with 14 minutes in the post-PERT cohort (p = 0.001). There was a significant decrease in level I (highest acuity) trauma activations pre-PERT and post-PERT (46% vs. 21%, p = 0.01), and the time to cardiotocography was significantly decreased post-PERT implementation (72 vs. .37 min, p = 0.01) CONCLUSION: Implementation of a multidisciplinary PERT improves time to evaluation by the OB team and time to cardiotocometry in the pregnant trauma patient. LEVEL OF EVIDENCE: Retrospective review, level IV.

Secondary maternal-fetal consequences to electrical injury: A literature review.

Electrical injuries can occur in pregnant women but currently their incidence is not completely known. Notwithstanding, those represent clinical important events such maternal and fetal death, which can be avoided if properly managed. The objective of this paper is to describe the results of electrical injury (high and low voltage), in pregnant women in scientific reports. A systematic search was performed with keywords "electrical injuries", "lightning injuries", "lightning strike", "pregnant women" and "pregnancy", using the databases: MedLine, Scielo, Lilacs, Clinical key, Web of Science, Scopus, Springer, Science Direct, Embase and Medic Latina. Filters like language, time, design and availability of text were not used. Descriptive analyses were carried out for variables such as maternal-fetal consequences, voltage and type of exposure, based on the reports identified. From the total 74 cases identified, 71.1% survived after the exposition. From the total live-births 28.6% did not show any alteration, 7.1% presented maceration and burns, while 64.3% had another outcome. Electric injury leads to fetal compromise and death in exposed pregnant women, mainly in the first hours after the injury. However, monitoring should be continued for the risk of complications such as placenta abruption, oligohydramnios and fetal distress. It is possible an underreporting of these events.

Factors associated with the severity of neonatal subgaleal haemorrhage following vacuum assisted delivery.

OBJECTIVE: To evaluate factors associated with subgaleal hemorrhage (SGH) severity following attempted vacuum-assisted delivery (VAD). STUDY DESIGN: This retrospective cohort study was conducted in a tertiary medical center. The population comprised parturients who delivered at our medical center during 2009-2018, and who underwent attempted VAD with singleton pregnancies that resulted in neonatal SGH formation. SGH severity was classified as mild and non-mild (moderate or severe). The main outcome measures were determinants associated with SGH severity. RESULTS: Among 350 neonates with SGH, the degree of severity was non-mild for 48 (13.7%). Compared to the mild group, in the non-mild group, small for gestational age was more common (8.2% vs. 2.6%, p = 0.04). Compared to the mothers in the mild group, in the non-mild group, the proportion with two or more deliveries was lower (0% vs. 7.3%, p = 0.05), gestational diabetes was more common (12.5% vs. 4.6%, p = 0.02), the rate of cervical ripening was higher (27.1% vs. 12.9%, p = 0.02), the duration of the second stage of delivery was longer (mean 177 vs. 152 min, p = 0.04), and the rate of two dislodgments was higher (31.2% vs. 15.2%, p = 0.006). On multivariate analysis, only cervical ripening (adjusted odds ratio [OR]: 2.50; 95% confidence interval [CI]: 1.20-5.26; P = 0.01 and second stage duration (adjusted OR: 1.13; 95% [CI]: 1.00-1.29; P = 0.05) were independently associated with more severe SGH. CONCLUSIONS: The duration of second stage and ripening of the cervix during induction of labor are independently associated with SGH severity following attempted VAD.

The Severity of Neurological Dysfunction in Preschool Children, Secondary to Damage Generated During the Perinatal Period, is Associated With a Pro-Inflammatory Pattern of Serum Molecules.

Disorders in the child's neurological development caused by perinatal risks can lead to long-term altered neurological signs that begin at an early age and involve persistent functional disorders. Recent data suggest that tissue dysfunction, not just acute damage, may initiate or perpetuate an inflammatory response. The aim of this study was to find out if any neurological dysfunction in preschool children secondary to damage generated during the perinatal period is associated with the magnitude of perinatal risks and long-term modifications in the serum concentrations of inflammatory molecules. The participants, aged 1-4 years, were on neurodevelopmental follow-up and rehabilitation therapy from the first three months of life and had no acute disease data. We classified the children into three groups according to the importance of their perinatal risks: low, medium, and high. The results show that 1) the magnitude of perinatal risks correlated with the severity of neurological dysfunction; 2) the greatest changes in the concentrations of the molecules of the inflammatory process were associated with the most altered neurological signs. This suggests that persistent nervous system dysfunction keeps inflammatory responses active even in the absence of an acute process of infection or damage.

Intrauterine big toenail imprints: A new cause of congenital skin dimples.

Congenital skin dimples (SD) are small cutaneous depressions that can be noted on any part of the body and may be caused by traumatic, mechanical, metabolic, and genetic factors as well as by exposure to infections or drugs. We describe 3 cases of unrelated healthy newborns displaying SD and discuss as a possible explanation the persistent friction of the big toenail onto the immature skin of the fetus during intrauterine life causing as depression in the skin.

Myelomeningocele sac associated with worse lower-extremity neurological sequelae: evidence for prenatal neural stretch injury?

OBJECTIVE: To determine whether the presence of a myelomeningocele (MMC) sac and sac size correlate with compromised lower-extremity function in fetuses with open spinal dysraphism. METHODS: A radiology database search was performed to identify cases of MMC and myeloschisis (MS) diagnosed prenatally in a single center from 2013 to 2017. All cases were evaluated between 18 and 25 weeks. Ultrasound reports were reviewed for talipes and impaired lower-extremity motion. In MMC cases, sac volume was calculated from ultrasound measurements. Magnetic resonance imaging reports were reviewed for hindbrain herniation. The association of presence of a MMC sac and sac size with talipes and impaired lower-extremity motion was assessed. Post-hoc analysis of data from the multicenter Management of Myelomeningocele Study (MOMS) randomized controlled trial was performed to confirm the study findings. RESULTS: In total, 283 MMC and 121 MS cases were identified. MMC was associated with a lower incidence of hindbrain herniation than was MS (80.9% vs 100%; P < 0.001). Compared with MS cases, MMC cases with hindbrain herniation had a higher rate of talipes (28.4% vs 16.5%, P = 0.02) and of talipes or lower-extremity impairment (34.9% vs 19.0%, P = 0.002). Although there was a higher rate of impaired lower-extremity motion alone in MMC cases with hindbrain herniation than in MS cases, the difference was not statistically significant (6.6% vs 2.5%; P = 0.13). Among MMC cases with hindbrain herniation, mean sac volume was higher in those associated with talipes compared with those without talipes (4.7 ± 4.2 vs 3.0 ± 2.6 mL; P = 0.002). Review of the MOMS data demonstrated similar findings; cases with a sac on baseline imaging had a higher incidence of talipes than did those without a sac (28.2% vs 7.5%; P = 0.007). CONCLUSIONS: In fetuses with open spinal dysraphism, the presence of a MMC sac was associated with fetal talipes, and this effect was correlated with sac size. The presence of a larger sac in fetuses with open spinal dysraphism may result in additional injury through mechanical stretching of the nerves, suggesting another acquired mechanism of injury to the exposed spinal tissue.
