Beyond Weight Loss: A Comprehensive Review of Pregnancy Management following Bariatric Procedures

The increasing prevalence of bariatric surgery among women of childbearing age raises critical questions about the correct management of pregnancy following these procedures. This literature review delves into the multifaceted considerations surrounding pregnancy after bariatric surgery, with a particular focus on the importance of preconception counselling, appropriate nutrition assessment, and the necessity of correct folic acid supplementation. Key areas of investigation include nutrient absorption challenges, weight gain during pregnancy, and potential micronutrient deficiencies. Examining the relationship between bariatric surgery and birth defects, particularly heart and musculoskeletal issues, uncovers a twofold increase in risk for women who underwent surgery before pregnancy, with the risk emphasized before folic acid fortification. In contrast, a nationwide study suggests that infants born to mothers with bariatric surgery exhibit a reduced risk of major birth defects, potentially associated with improved glucose metabolism. In addition, this review outlines strategies for managing gestational diabetes and other pregnancy-related complications in individuals with a history of bariatric surgery. By synthesizing existing literature, this paper aims to provide healthcare providers with a comprehensive framework for the correct management of pregnancy in this unique patient population, promoting the health and well-being of both mother and child.

Bilateral Renal Ectopia-Prenatal Diagnosis

This report explores the diverse spectrum of congenital anomalies of the kidney and urinary tract (CAKUT), ranging from asymptomatic presentations to the most severe form characterized by bilateral renal agenesis. Genitourinary anomalies, a prevalent subset within this domain, account for a significant proportion, constituting 15-20% of anomalies identified during prenatal screening. An ectopic kidney is defined by the presence of an empty renal fossa and the displacement of the kidney from the lumbar region to alternative locations, with the pelvic region emerging as the most prevalent site. The reported case involves bilateral renal ectopia with unilateral duplex kidney. Initial suspicions of a renal anomaly arose during the first trimester, leading to a definitive diagnosis in the second trimester. The patient underwent regular monitoring every four weeks, ultimately delivering a healthy baby at term. This case underscores the frequency of renal anomalies, emphasizing that a considerable proportion remains asymptomatic. These findings contribute to a broader understanding of congenital renal anomalies, their varied manifestations, and the importance of vigilant prenatal screening for early detection and management.

Body Stalk Anomaly

Abdominal wall defects encompass three primary classifications: gastroschisis, omphalocele and anomalies resembling body stalk. Potential causative factors include early amnion rupture, amniotic bands, vascular disruptions or abnormal folding of the embryo. The prevalence of these defects stands at 1 in 14,000 live births. Body stalk anomaly is characterized by a substantial abdominal defect coupled with spine and limb anomalies, along with a very short or absent umbilical cord. We present a case of a rare abdominal defect known as body stalk anomaly, the most severe form of this spectrum of diseases. The diagnosis of this anomaly was established during the first trimester of pregnancy. Subsequently, the patient opted for pregnancy termination and chose not to undergo genetic testing. The anatomo-pathological results confirmed the findings. Body stalk anomaly is not compatible with life; therefore, early identification and understanding the clinical implications of this rare anomaly for informed decision-making in prenatal care are very important.

Preconceptional Counseling in Women with Hyperthyroidism

Preconception evaluation of couples wishing to conceive is an important step toward a healthy pregnancy and it is especially important in people with a chronic condition or at genetic risk. The most common endocrine disorders in women at reproductive age are those involving the thyroid gland and it is well recognized that hyperthyroidism (HT), over-function of the thyroid gland, is associated with risks of maternal, fetal, and neonatal complications. The aim of this paper is to review the latest evidence regarding the components of preconception counseling in women with HT that contemplate a pregnancy. We also want to raise awareness among healthcare professionals about the importance of periconceptional counseling in improving pregnancy outcomes and avoid maternal and fetal complications related to thyroid dysfunction. In women with Graves' disease seeking pregnancy, it is essential to discuss all the treatment options along with the associated risks and benefits. Extensive prospective studies are still needed to understand the implications of current recommended strategies for the management of HT in preconception and during pregnancy.

Amniotic Band Syndrome-Prenatal Diagnosis

This is a case of a fetus affected by an amniotic band detected at 20 weeks of gestation. A presumptive diagnosis was made based on the ultrasound features. The ultrasound showed an abnormally developed right lower limb and no other associated fetal abnormalities. The unilaterality of the defect decreases the chances of genetic abnormality or an early vascular insult. The postnatal examination of the newborn concluded that the prenatal diagnosis was right.

Prenatal Ultrasound Diagnosis of Klippel-Trenaunay Syndrome

Klippel-Trenaunay syndrome (KTS) is a very rare vascular malformation syndrome also referred to as a capillary-lymphatic-venous malformation with unknown aetiology. The aim of our paper is to highlight interesting images, regarding a rare case of foetal Klippel-Trenaunay syndrome diagnosed prenatally in our department and confirmed postnatally with a favourable evolution during the gestation and neonatal periods. This case was diagnosed at 26 weeks gestation and characterised through ultrasound by the presence of superficial multiple cystic structures of different sizes spreading over the left leg with hemihypertrophy and reduced mobility. The cystic lesions were spreading to the left buttock and the pelvic area. The right leg and upper limbs had normal appearance with good mobility. There were no signs of hyperdynamic circulation or foetal anaemia, but mild polyhydramnios was associated. The ultrasound findings were confirmed postnatally, the left leg presented multiple cystic lesions and port wine stains, and there was hypertrophy and fixed position, with favourable evolution at 6 months of life, when the size of the lesions began to decrease and the mobility of the leg improved.

Skeletal Dysplasia: A Case Report

This paper presents a rare case of fetal hydrops detected at just 23 weeks of gestation in a 22-year-old woman's first pregnancy. The fetal ultrasound revealed severe skeletal anomalies, craniofacial deformities, and thoracic abnormalities, suggesting a complex and severe skeletal dysplasia, potentially type IA Achondrogenesis-a lethal autosomal recessive condition marked by ossification delay. This case highlights the significance of advanced genetic testing, such as next-generation sequencing (NGS) and whole-genome sequencing (WGS), in diagnosing and understanding skeletal dysplasias. Skeletal dysplasias represent a group of genetic disorders that affect osteogenesis. The prevalence of this condition is 1 in 4000 births. Sadly, 25% of affected infants are stillborn, and around 30% do not survive the neonatal period. There is a wide range of rare skeletal dysplasias, each with its own specific recurrence risk, dysmorphic expression, and implications for neonatal survival and quality of life. When skeletal dysplasia is incidentally discovered during routine ultrasound screening in a pregnancy not known to be at risk of a specific syndrome, a systematic examination of the limbs, head, thorax, and spine is necessary to reach the correct diagnosis. Prenatal diagnosis of skeletal dysplasia is crucial for providing accurate counselling to future parents and facilitating the proper management of affected pregnancies. An accurate diagnosis can be a real challenge due to the wide spectrum of clinical presentations of skeletal dysplasia but advances in imaging technologies and molecular genetics have improved accuracy. Additionally, some of these skeletal dysplasias may present clinical overlap, making it especially difficult to distinguish. After the 11th revision of genetic skeletal disorder nosology, there are 771 entities associated with 552 gene mutations. The most common types of skeletal dysplasia are thanatophoric dysplasia, osteogenesis imperfect, achondroplasia, achondrogenesis, and asphyxiating thoracic dystrophy.

Sonographic Detection of Fetal Cholelithiasis

Fetal biliary lithiasis is a benign condition characterized by the presence of gallstones in the gallbladder of a developing fetus. It is typically detected incidentally during a routine obstetric echography. The incidence of this condition varies from 0.03% to 2.3%. In most cases, fetal cholelithiasis resolves spontaneously and has an excellent prognosis. However, there are certain risk factors that may contribute to its development. Maternal factors that increase the risk of fetal cholelithiasis include placental abruption, elevated estrogen levels, narcotic use, diabetes, enteral nutrition, and specific medications, such as ceftriaxone, furosemide, and prostaglandin E2. Fetal factors that can contribute to the condition include Rhesus or ABO blood group incompatibility, congenital anomalies affecting the cardiovascular, gastrointestinal, or urinary systems, twin pregnancies with the fetal demise of one twin, genetic anomalies such as trisomy 21, chromosomal aberrations, cystic fibrosis, growth restriction, oligohydramnios, hepatitis, or idiopathic causes. Usually, the gallstones spontaneously resolve before or after birth without requiring specific treatment. However, in rare instances, complications can arise, such as the formation of biliary sludge, inflammation of the gallbladder (cholecystitis), or obstruction of the bile ducts. If complications occur or if the gallstones persist after birth, further evaluation and management may be necessary. Treatment options can include medication, minimally invasive procedures, or, in severe cases, surgical removal of the gallbladder.

Microduplication 3p26.3p24.3 and 4q34.3q35.2 Microdeletion Identified in a Patient with Developmental Delay Associated with Brain Malformation

Microdeletions and microduplications are involved in many of prenatal and postnatal cases of multiple congenital malformations (MCM), developmental delay/intellectual disability (DD/ID), and autism spectrum disorders (ASD). Molecular karyotyping analysis (MCA), performed by DNA microarray technology, is a valuable method used to elucidate the ethology of these clinical expressions, essentially contributing to the diagnosis of rare genetic diseases produced by DNA copy number variations (CNVs). MCA is frequently used as the first-tier cytogenetic diagnostic test for patients with MCM, DD/ID, or ASD due to its much higher resolution (≥10×) for detecting microdeletions and microduplications than classic cytogenetic analysis by G-banded karyotyping. Therefore, MCA can detect about 10% pathogenic genomic imbalances more than G-banded karyotyping alone. In addition, MCA using the Single Nucleotide Polymorphism-array (SNP-array) method also allows highlighting the regions of loss of heterozygosity and uniparental disomy, which are the basis of some genetic syndromes. We presented a case of a five-year-old patient, with global development delay, bilateral fronto-parietal lysencephaly, and pachygyria, for which MCA through SNP-Array led to the detection of the genetic changes, such as 3p26.3p24.3 microduplication and 4q34.3q35.2 microdeletion, which were the basis of the patient's phenotype and to the precise establishment of the diagnosis.

Neurological Manifestations of SARS-CoV2 Infection: A Narrative Review

The COVID-19 virus frequently causes neurological complications. These have been described in various forms in adults and children. Headache, seizures, coma, and encephalitis are some of the manifestations of SARS-CoV-2-induced neurological impairment. Recent publications have revealed important aspects of viral pathophysiology and its involvement in nervous-system impairment in humans. We evaluated the latest literature describing the relationship between COVID-19 infection and the central nervous system. We searched three databases for observational and interventional studies in adults published between December 2019 and September 2022. We discussed in narrative form the neurological impairment associated with COVID-19, including clinical signs and symptoms, imaging abnormalities, and the pathophysiology of SARS-CoV2-induced neurological damage.

Herlyn-Werner-Wunderlich Syndrome: Case Report and Review of the Literature

Herlyn-Werner-Wunderlich (HWW) syndrome is a very rare congenital malformation of the urogenital tract involving both the müllerian and the wolffian ducts, and it consists of the association of didelphys uterus, ipsilateral obstructed hemivagina, and ipsilateral kidney agenesis. Its etiology is related to the abnormal development of two embryonic structures-mesonephros and paramesonephros-although its precise mechanism is not known, but theories involving signaling molecules and gene expression are studied for potential explanations. Because of its rarity, there is limited literature on this subject. We present a case diagnosed in our department and elaborate on management. In HWW syndrome, symptoms appear after menarche and include pelvic pain, with progressive intensity due to the developing of hematocolpos. Menstruation may be present or absent depending on the type of anomaly. The use of magnetic resonance imaging (MRI) is the most recommended method of investigation since, in most cases, at this age, sexual life has not started yet and transvaginal ultrasound cannot be used. Surgical treatment in our case consisted of an exploratory laparoscopy followed by a vaginal surgical approach to resect the vaginal septum of the obstructed hemivagina.

Near-Infrared Spectroscopy Usefulness in Validation of Hyperventilation Test

Background: The hyperventilation test is used in clinical practice for diagnosis and therapeutic purposes; however, in the absence of a standardized protocol, the procedure varies significantly, predisposing tested subjects to risks such as cerebral hypoxia and ischemia. Near-infrared spectroscopy (NIRS), a noninvasive technique performed for cerebral oximetry monitoring, was used in the present study to identify the minimum decrease in the end-tidal CO2 (ETCO2) during hyperventilation necessary to induce changes on NIRS. Materials and Methods: We recruited 46 volunteers with no preexisting medical conditions. Each subject was asked to breathe at a baseline rate (8−14 breaths/min) for 2 min and then to hyperventilate at a double respiratory rate for the next 4 min. The parameters recorded during the procedure were the regional cerebral oxyhemoglobin and deoxyhemoglobin concentrations via NIRS, ETCO2, and the respiratory rate. Results: During hyperventilation, ETCO2 values dropped (31.4 ± 12.2%) vs. baseline in all subjects. Changes in cerebral oximetry were observed only in those subjects (n = 30) who registered a decrease (%) in ETCO2 of 37.58 ± 10.34%, but not in the subjects (n = 16) for which the decrease in ETCO2 was 20.31 ± 5.6%. According to AUC-ROC analysis, a cutoff value of ETCO2 decrease >26% was found to predict changes in oximetry (AUC-ROC = 0.93, p < 0.0001). Seven subjects reported symptoms, such as dizziness, vertigo, and numbness, throughout the procedure. Conclusions: The rise in the respiratory rate alone cannot effectively predict the occurrence of a cerebral vasoconstrictor response induced by hyperventilation, and synchronous ETCO2 and cerebral oximetry monitoring could be used to validate this clinical test. NIRS seems to be a useful tool in predicting vasoconstriction following hyperventilation.

Ovarian Germ Cell Tumors: Pictorial Essay

Ovarian germ cell tumors of the ovary represent a histologically heterogenous group of tumors with a high incidence at reproductive age. Patients with this pathology are very often young women with amenorrhea. The aim of this article is to present a pictorial essay of this rare pathology and to promote a national tumor registry and protocol. The treatment is individualized according to age, and fertility-sparing surgery is the actual standard of surgical treatment for young patients in early stage of the disease.

Multiple sclerosis in pregnancy. Treatment options and outcomes: a review

Background. Women are commonly diagnosed with multiple sclerosis during reproductive age. There is need for disease control management during pregnancy, taking into consideration potential maternal and fetal risks. This review article aims to summarize what is acknowledged so far regarding treatment options of multiple sclerosis and outcomes in pregnancy, providing up-to-date information. Methods. In order to write this review a comprehensive literature electronic search for journal articles and guidelines regarding multiple sclerosis during pregnancy was undertaken. Results and conclusion. Multiple sclerosis management in pregnancy is a challenging issue. The use of disease-modifying drugs has improved both the course of the disease and the attitude towards pregnancy in patients living with multiple sclerosis. Pregnancy appears to have a protective effect on disease activity, particularly during the third trimester.

Management of unruptured brain aneurysms during pregnancy and puerperium

Aneurysms are sac-like dilatations of weakened wall areas within blood vessels. Cardiovascular related issues, such as hypertension, can put one at risk of developing such complications, with the possibility of rupturing. In the case of intracranial aneurysms, an outpouching forms where there is turbulent blood flow, often at the bifurcation of arteries. Depending on the morphology and location, different treatments need to be considered, but during pregnancy, further physiological changes also factor into decision making. In pregnant patients, intracranial hemorrhage cases are relatively low, yet they cause a high mortality rate amongst women, hence early detection and management of unruptured aneurysms is of significant importance.

Migraine and pregnancy

Background. Migraine is a frequent neurological disorder affecting mostly women in the childbearing age. It is influenced by fluctuation of female hormones, especially estrogen levels. Objectives. This review aims to describe the expression of migraine during the reproductive ages summarizing the diagnosis and effective, available treatment options. Materials and Methods. We performed a literature review searching relevant information on the subject in PubMed and Medscape databases. Outcomes. It reveals that during the first trimester due to symptoms of hyperemesis gravidarum, migraine attacks can exacerbate, while, through second and third trimester when estrogen levels rise, women report relief of symptoms. Therapy includes firstly behavioural approach and secondly pharmacological drugs along with non-invasive procedures, some still under investigation for pregnant state. For mild cases the first line is acetaminophen alone or together with antiemetics and in more severe cases or in women with past history of migraine triptans can used as the mainstay therapy. Conclusions. Despite recent discoveries on therapy and drugs, our understanding of the way medications may affect the fetus or new-born is incomplete and further evidence is needed, bringing potential for improved management of migraine during pregnancy.

Moyamoya disease during pregnancy and childbirth

Moyamoya disease (MMD) is a chronic vasculopathy characterized by progressive bilateral stenosis and occlusion of the terminal portion of the internal carotid artery (ICA) and the presence of an abnormal vascular network at the base of the brain, termed Moyamoya vessels (MMV). The main presentations of MMD are ischemia and hemorrhage, and diagnosis is done via angiography. Cerebral events were reported in 5.1% of pregnancies of MMD diagnosed mothers, in Japan. In the case of MMD diagnosis due to cerebrovascular events during gestation, 34.7% of patients presented with an ischemic event, while 69.5% suffered from hemorrhage. During gestation, hemorrhagic events were found to occur mostly antepartum, after 24 weeks of gestation, while cerebral infarction peaked 3-7 days after delivery. No treatment has been found to halt or reverse the progress of the disease. Interventions focus on reducing the risk of stroke and cognitive disfunction as a result of ischemia. In the case of pregnant women suffering hemorrhage due to MMD, conservative treatment, as well as ventricle puncture and drainage were to be efficient, and did not severely impact the child. When diagnosed before pregnancy occurs, MMD under treatment does not pose a significantly increased risk of complications, compared to pregnancies in unaffected women. No evidence suggests that MMD is a contraindication for pregnancy.

Antiviral medication to prevent fetal transmission of maternal CMV during pregnancy

Background. Cytomegalovirus infection represents the most frequent congenital viral infection, with serious consequences on newborns. Neurosensorial hearing loss is the principal outcome, but also, the infection can cause other central nervous system’s anomalies. Although CMV infection can have a major impact on fetal development, there are not clear directions to follow yet, to prevent or treat this condition. Therefore, our purpose with this paper is to update the knowledge regarding the treatment options in order to prevent fetal transmission of maternal CMV infection, based on the latest data from the specialized literature in this field. Methods. Electronic research and analysis of the relevant articles published mainly in the last 5 years were performed, consulting the web platforms PubMed, ScienceDirect, Mendeley and ClinicalTrials.gov. Results and conclusions. To date, there is not enough evidence to reach a consensus on therapeutic methods to prevent or to treat fetal CMV infections and, as a consequence, antenatal screening is not justified. Many pharmaceutical companies work on vaccines to prevent CMV infection, but the results are only from studies’ second phase. Information on efficiency of hyperimmunoglobulin is mixt and it is necessary to clarify the dosage. Among antiviral agents, valaciclovir, which was studied in recent clinical trials, seems to have the best efficiency to prevent fetal transmission of maternal CMV infection and the best safety profile. Valganciclovir has possible embryotoxic effects, but higher potency and information on it are available only from case reports. The interest of scientific community on this topic is high, thus many studies are underway to bring new clarifications.

Ultrasound Appearance of Fetal Posterior Fossa and a Case Report of Prenatal Diagnosis of Dandy-Walker Malformation

Prenatal sonographic assessment of the posterior fossa in the mid-sagittal plane at 11-14 weeks' gestation has been highlighted as an essential diagnostic step by the current literature. This approach is used for the early detection of open spina bifida during the first trimester by analyzing the three spaces of the posterior fossa: brain stem, the fourth ventricle and cisterna magna. Abnormal size of fetal posterior fossa spaces is an important sign in the diagnosis of fetuses with central nervous system malformation and needs to be submitted for differential diagnosis when any alterations are observed. Among them, Dandy-Walker malformation is one of the major causes of congenital hydrocephalus, being a rare condition, with poor-prognosis, manifested by enlarged posterior fossa. On the basis of available evidence, the assessment of the fetal posterior cranial fossa is feasible from 11 to 14 weeks gestational age and it is believed that abnormal appearance of the posterior fossa at this stage of pregnancy could improve early detection of Dandy-Walker malformation by prompting an early second trimester ultrasound evaluation.

Uptake of the COVID-19 vaccine in pregnancy

Coronavirus disease 2019 (COVID-19) has rapidly become a global pandemic with a devastating morbidity and mortality. Pregnant women seem to be at increased susceptibility to have a severe disease and suffer adverse pregnancy outcomes. The only solution to mitigate this pandemic is prophylaxis by mass vaccination. We report a review based on current literature about the evidence available on efficacy and safety of anti-COVID-19 vaccines in pregnancy to aid women decide whether to vaccinate or not, while being pregnant or lactating. Studies so far did not find concerning maternal or fetal outcomes and show a similar efficiency of mRNA vaccines as in non-pregnant population. Moreover, anti-SARS-CoV-2 antibodies resulted from the vaccination seem to be transferred to the newborn through the placenta or the breastmilk building up the neonatal immunity. However, the exclusion from clinical trials created a great deficiency of evidence regarding the vaccination in this high-risk population resulting in their reluctance.

HIV medication to prevent fetal infection during pregnancy

When it has been declared a global epidemic, HIV infection became a challenge for medical world. Even if there is only one healed case cited in literature, treatment for HIV-infection have evolved during time leading to very good results in disease control and limitation of virus transmission. When it comes for viral transmission, an essential research topic became the prevention of mother to fetal transmission. In the long run, many discovered antiretroviral drugs proved to be efficient in controlling HIV infection during pregnancy and thereby in reducing the risk of viral transmission to the fetus. But along with use of the HIV-treatment in pregnancy, many questions have appeared. Are the drugs safe for the fetus, or are there any adverse pregnancy outcomes? Should the treatment be adjusted for the desired results in pregnancy, or should the initial treatment be changed when the pregnancy is diagnosed? Many retrospective or prospective observational studies and comparative studies have been conducted in order to answer those questions and to analyze the efficacy and the safety of mostly used antiretroviral drugs in pregnancy. This article reviews the existing studies, guidelines and recommendations regarding the combined antiretroviral HIV treatment during pregnancy for fetal infection prevention.

Parvovirus infection in fetal life. Case report and recent literature updates

Background. The parvovirus B19 (B19V) belongs to the Parvoviridae family, genus Erythrovirus, and is a virus that causes a common childhood disease called erythema infectiosum, also largely known as the fifth childhood disease. The clinical appearance is marked by the “slapped cheek” facies and an erythematous rash localized mainly on the extremities and on the trunk. Most people gain immunity during childhood, and when it occurs in pregnancy in non-immunized women, there are some serious complications for the fetus that can occur. B19V infection in pregnancy can conduct to fetal loss or severe hydrops fetalis, due to the risk of vertical transmission to the fetus and the virus tropism for the erythropoietic fetal stem cells with subsequent cell destruction and fetal anemia. Invasive treatment, as intrauterine fetal transfusion, is necessary for the cases of severe fetal anemia with good survival rates afterwards. The purpose of this review is to update the current knowledge regarding the best management of severe fetal anemia and other complications related to B19V infection in pregnancy, based on the latest data from literature and guidelines. Methods. Electronic research for relevant articles published in the last years was made, with the usage of PubMed, Medline, Cochrane Data Base, and the current international guidelines promoted by the Obstetrics and Gynecology Societies. Results and conclusions. The importance of prenatal detection of non-immunized women by serologic testing for parvovirus B19 should not be overlooked, and subsequent follow-up should be recommended in order to lower the incidence of fetal complications associated with developing the disease in pregnancy, especially during epidemics. In case of P19V infection in pregnancy, serial ultrasounds and lab tests should be performed in order to determine the impact on the fetus and the apparition of fetal hydrops. The future moms who are not immunized to B19V should be advised about the risk of vertical transmission and the associated fetal sequelae that can occur. Assessment for maternal disease and for fetal impairment has to become a priority when there are signs of primary infection in pregnancy.

Oxytocin and vasopressin in the hippocampus

Oxytocin (OXT) and vasopressin (AVP) are related neuropeptides that exert a wide range of effects on general health, homeostasis, development, reproduction, adaptability, cognition, social and nonsocial behaviors. The two peptides are mainly of hypothalamic origin and execute their peripheral and central physiological roles via OXT and AVP receptors, which are members of the G protein-coupled receptor family. These receptors, largely distributed in the body, are abundantly expressed in the hippocampus, a brain region particularly vulnerable to stress exposure and various lesions. OXT and AVP have important roles in the hippocampus, by modulating important processes like neuronal excitability, network oscillatory activity, synaptic plasticity, and social recognition memory. This chapter includes an overview regarding OXT and AVP structure, synthesis, receptor distribution, and functions, focusing on their relationship with the hippocampus and mechanisms by which they influence hippocampal activity. Brief information regarding hippocampal structure and susceptibility to lesions is also provided. The roles of OXT and AVP in neurodevelopment and adult central nervous system function and disorders are highlighted, discussing their potential use as targeted therapeutic tools in neuropsychiatric diseases.

Risk of vertical transmission of chronic viral infections after invasive prenatal procedures

OBJECTIVES

Invasive prenatal procedures including amniocentesis, chorionic villus sampling (CVS) can be prenatally indicated for diagnostic purposes. Chronic viral infections with Human Immunodeficiency Virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV) are not uncommon in women of reproductive age. The aim of this narrative literature review is to provide guidance on the best clinical practice in antenatal invasive testing and fetal surveillance in pregnancies with HIV, HCV, HBV and treponema pallidum infected women.

MATERIAL AND METHODS

A review of the literature was conducted in the database of PubMed to select full-length articles published in peer-reviewed journals between 1990 and 2020. The keywords along with respective combinations included in the search strategy were invasive testing, prenatal diagnosis, amniocentesis, chorionic villus sampling, cordocentesis, fetoscopy, chronic viral infections, hepatitis B, hepatitis C, HIV, treponema pallidum, syphilis, vertical transmission, MTCT.

RESULTS

For patients with hepatitis B infection, it is important to assess the HBeAg status and HBV DNA levels and for those patients with high viral load, antiviral therapy (Tenofovir) for a few weeks may be needed to reduce the viral load prior to the invasive procedure. In women positive for HCV, the viral load and HIV status should be assessed to establish the risk of vertical transmission; while for patients with HIV, highly active antiretroviral therapy administration and low viral load are predictive for reduced vertical transmission even after performing an invasive procedure. In all cases invasive procedure should be replaced by non-invasive prenatal testing if this is a feasible alternative and when invasive testing is indeed required, transplacental passage should be avoided.

The Potential Benefit of Hydroxychloroquine in Chronic Placental Inflammation of Unknown Etiology Associated with Adverse Pregnancy Outcomes

The placenta is the site of connection between maternal and fetal circulation, and the liaison is established early in pregnancy. A large variety of pregnancy complications such as preterm birth, fetal growth restriction, or pregnancy loss have placental expression and can be accompanied in some cases of acute or chronic identifiable placental inflamatory lesions. Chronic placental inflammatory (CPI) lesions include chronic villitis of unknow etiology (CVUE), chronic intervillositis of unknown etiology, CIUE (also described as chronic histiocytic intervillositis, CHI), and chronic deciduits. Hydroxychloroquine (HCQ) has been prescribed with good results during pregnancy to prevent adverse perinatal outcomes in maternal autoimmune conditions. Its success has paved the way to its use in CPI as CIUE/CHI; however, to date, there are no prospective, informatively designed, controlled studies on its value in these setting. This review aims to explore the potential role of HCQ in CPI of unknown etiology. Ideally, properly designed, probably multicentric studies should be undertaken to fully understand HCQ's role for prevention of adverse pregnancy outcomes after a chronic placental inflammation.

Prenatal features of mandibulofacial dysostosis Guion-Almeida Type

Facial dysostoses are clinically and genetically heterogeneous conditions characterized by congenital craniofacial anomalies which result from abnormal development of the first two pharyngeal arches and their derivatives during embryogenesis. Mandibulofacial dysostosis Guion-Almeida type (MFDGA) is a rare and relatively new syndrome described in the literature, first identified by Guion-Almeida et al. in 2000 and 2006. Another 108 cases have been documented after that. Prenatal diagnosis of this syndrome has not been described yet. Here we present the prenatal ultrasound findings in a case where MFDGA was confirmed after delivery. We suggest that MFDGA should be included in the prenatal differential diagnosis of syndromes with micrognathia and craniofacial anomalies.

Medulloblastoma Presenting as Severe Headache during Pregnancy: A Case Report and Review of the Literature

Headache is a common complaint during pregnancy and the puerperium. The differentiation between a benign headache and a headache that has an underlying more endangering cause, such as an intracranial tumor, can be difficult and often requires diagnostic procedures and brain imaging techniques. We report the case of an 18-year-old female patient who developed clinical symptoms-persistent headache followed by neurological deficit-in the last part of her pregnancy. A medulloblastoma (MB) was diagnosed and treated after delivery. We review 11 other cases of MB in pregnancy reported in the literature. The most common clinical manifestation at diagnosis was headache followed by neurological deficits. We discuss the association of brain tumor growth with physiological changes during pregnancy. We conclude that clinical features of intracranial tumors can be misinterpreted as pregnancy-related symptoms and should not be dismissed.

Incidence of Emergency Peripartum Hysterectomy in a Tertiary Obstetrics Unit in Romania

Background and Objectives: Emergency peripartum hysterectomy (EPH) is a life-saving surgical procedure performed when medical and surgical conservative measures fail to control postpartum hemorrhage. The objective of this study was to estimate the incidence of EPH and to determine the factors leading to this procedure and the maternal outcomes. Materials and Methods: A retrospective cohort study with all cases of EPH performed at Filantropia Clinical Hospital in Bucharest between January 2012 and May 2021. Results: There were 36 EPH, from a total of 36,099 births recorded. The overall incidence of EPH was 0.99 per 1000 deliveries, most cases being related to placenta accreta spectrum disorder and uterine atony. Conclusions: Peripartum hysterectomy is associated with an important maternal morbidity rate and severe complications. Efforts should be made to reduce the number of unnecessary cesarean deliveries.

Risk factors and protective factors in pregnant adolescents

Pregnancy and birth in adolescence involve certain risks for both mother and fetus. Psychologically, adolescent mothers have a higher risk of developing emotional disorders. This paper is a review based on information from the literature. The analysis was limited to articles in English published between January 1, 2000 and September 1, 2021 on PubMed, ScienceDirect and Google Scholar using the following keywords: pregnancy, adolescents, adolescence, risk factors, support factors, psychological interventions. In the context of pregnancy in this challenging stage of adolescence girls should be referred to pre- and postnatal counseling programs or support groups so that they develop healthy relationships and support networks.

Methicillin-resistant Staphylococcus aureus infections in postpartum period

The overall risk of methicillin-resistant Staphylococcus aureus (MRSA) in obstetric populations is unknown. MRSA infection incidence has increased in pregnant women and neonates even if prevention techniques of MRSA have improved. MRSA infections affect both mothers and their infants. MRSA is the most common pathogen responsible for postpartum mastitis. There are also other postpartum infections with MRSA such as cellulitis, pelvic thrombophlebitis, pneumonia, septicemia, cesarean wound infections, episiotomy infections and urinary tract infections. The objectives of this review were to identify the most frequent risk factors for postpartum MRSA infection and to determine the frequency of antibiotic-resistant Staphylococcus aureus infections after delivery. A literature review was conducted using PubMed and we used the following key words “MRSA infection in postpartum”, “risk factors for postpartum MRSA infection”. We are included in our review 27 articles from the last 20 years which presented rare cases of MRSA infection in postpartum and those which identified the risk factors of this infection after delivery. Infections with MRSA appear to be more frequent among pregnant women colonized with MRSA. Early identification of MRSA, early diagnosis and appropriate treatment of infection is mandatory for a good prognosis. By now, vigilance and effective MRSA prevention strategies are considered essential to limit the spread and infection.

Follow-up after Ductal Carcinoma In Situ Treatment

Follow-up after ductal carcinoma in situ (DCIS) treatment is a matter of debates and a strategy has not yet been adopted. The current follow-up strategy is not distinguished from that of invasive breast cancers. Although in recent years DCIS is seen as a distinguished category of breast cancer, the follow-up strategy does not reflect this new paradigm. It continues to use the same strategy like in invasive breast cancer and practices differ widely worldwide or even in the same country. A consensus is needed to keep safety of patients and save costs without compromising the outcome.

Counseling Process in Ductal Carcinoma In Situ

Ductal carcinoma in situ (DCIS) is a heterogenous group of intraductal proliferations, without a known natural history and predictability and without being considered an obligatory precursor of invasive ductal cancer. Lack of biological markers of predictability makes its evolution uncertain. Because DCIS is not an obligatory precursor of invasive breast cancer, counselling will not be made like in invasive cancer. Counselling must recognize the uncertainty of progression toward invasive disease and every patient must be correctly and empathically informed so that she is as involved as possible in the decision-making process.

Malignant Phyllodes Tumor of the Breast and Pregnancy: A Rare Case Report and Literature Review

Phyllodes Tumor (PT) is a rare fibroepithelial breast tumor that can behave differently depending on its biologic features. Traditionally, PTs are classified by their histologic features into benign, borderline, and malignant. In most cases that were reported, all PTs may recur, but only the borderline and malignant PT can metastasize. PT usually occurs as a breast lump or accidental finding on ultrasound (US) examination. The clinical features include a well-defined breast mass, regular or lobulated. The diagnosis is based on the integration of morphology features, but remains challenging, particularly in the distinction from fibroadenomas. We report a case of a 36-year-old patient who presented for a voluminous breast mass, rapidly growing in the past 3–4 months. At presentation, the patient was 19 weeks pregnant. The breast tumor had the clinical and US aspect of PT. A core needle biopsy was obtained, confirming a benign PT, and local excision was performed with no postoperative complications. The final pathology report showed a borderline PT with close resection margins of 1 mm. Immunohistochemistry (IHC) established the diagnosis of malignant PT with heterologous sarcomatous differentiation. The case was discussed in the multidisciplinary tumor board (MDT) and mastectomy was recommended. The patient fully consented but refused surgery at 25 weeks’ gestation, fearing premature delivery. The right breast was closely monitored by US, and at 9 weeks after the first surgery, signs of local recurrence were detected. At 35 weeks’ gestation, right mastectomy was performed, with no perioperative complications. The pregnancy was closely followed up and no complication were found. The final pathology report describes multiples PT recurrences with heterologous sarcomatous differentiation. The pregnancy outcome was uneventful, and the patient delivered a healthy child vaginally at term with no peripartum complication. Postpartum, a computer tomography (CT) examination of the head, thorax, abdomen and pelvis was performed, with no evidence of metastases. Adjuvant chemotherapy and radiotherapy completed the treatment. The follow-up and CT scan showed no metastases or further recurrence 4 years after diagnosis. In conclusion, diagnosis of PT can be difficult, especially because of the easy confusion with fibroadenoma of the breast. There are rare cases when a pathology exam needs further assessment and IHC is recommended for accurate diagnosis. Although malignant PT is rare and accounts for <1% of all breast cancers, the diagnosis and treatment that are recommended are based on the reported cases. Moreover, when complete surgical excision is achieved, the rates of recurrence and distant metastases are low, and adjuvant therapy might not be necessary.

Platelet Changes in Pregnancies with Severe Early Fetal Intrauterine Growth Restriction

Background and Objectives: In this study, we investigated the changes of platelet count and other platelet indices, such as mean platelet volume (MPV), in cases with severe early intrauterine fetal growth restriction (IUGR). Materials and Methods: We retrospectively analyzed all pregnancies diagnosed with severe early onset IUGR, that were followed up in our hospital between 2010 and 2015 (before implementation of screening and prophylaxis with aspirin). Pregnancies which resulted in birth of a newborn with a birthweight less than 5th percentile for gestational age, that required delivery for fetal or maternal indication before 32 weeks, were selected for the IUGR group. The IUGR cases were divided into two groups according to preeclampsia (PE) association. All cases with a complete blood count (CBC) performed within 7 days prior to delivery were included in the study, as the IUGR group. The control group included normal singleton pregnancies, delivered at term, with birthweight above 10th centile and a CBC taken at 30–32 weeks. Results: There was a significant difference in platelet count and MPV values between the IUGR group and control. Cases with IUGR presented lower platelet count and higher MPV values; there was no significant difference of these parameters when PE was associated with IUGR. Conclusions: Our results suggest that in cases of severe early IUGR, even in the absence of clinically diagnosed PE, there may be maternal endothelial damage and platelet consumption in the systemic and uteroplacental circulation. Platelet count and MPV values are simple and widely available laboratory tests that might be used as indicator of placental insufficiency; however, prospective data are required to establish the mechanistic link and to which extent these parameters are good predictors of severity or adverse perinatal outcomes.

Prevention of neonatal group B streptococcal disease

Group B streptococcal (GBS) disease and its early onset continues to pose major economic and perinatal implications regarding maternal and neonatal morbidity and mortality rates and methods of treatment. Universal GBS screening via rectovaginal culture is now recommended between 36 and 37 weeks and 6 days of gestation for all pregnant women. Timely identification of groups of women suitable for intravenous intrapartum antibiotic prophylaxis of GBS early onset infection has also proven to be effective, although less so than the universal screening approach.

Rubella in pregnancy. Still a concern

Rubella is the most important preventable cause of fetal malformations. Infection during pregnancy can result in fetal growth restriction, miscarriage, fetal death or it can cause congenital rubella syndrome with visual, auditory and cardiac defects. There are still many developping countries which are endemic for Rubella, despite major vaccination programmes available worldwide. There are no clinical symptoms present in approximately one half of cases, so diagnosis relies on serological testing if infection is suspected. Detection of IgM specific antibodies is the method of choice for diagnosis of both postnatal and congenital rubella. It has high sensitivity, but false positive cases are always possible after infection with other viruses like parvovirus B19, Epstein-Barr virus, cytomegalovirus and measles. Prevention relies on preconception care when it is recommended to check the immunity status for rubella (IgG) and for non-immunized patients, vaccination should be indicated.

Coxsackie virus B infection and pregnancy

Frequently, enteroviral infection with Coxsackie virus B (CV-B) goes unnoticed, without or only with mild symptoms. The infection is well known for the gastro-intestinal transmission, but recently, the severe forms of neonate’s infection, suggested that vertical transmission should not be neglected and moreover the fetal consequences should be studied. This review relates the most important findings regarding infection with CV-B during pregnancy, most of the information being based on murine studies. It seems that CV-B infection is associated with high rate of abortion and could also impair fertility. Regarding long term effects, CV-B might cause autoimmune diseases, congenital heart defects and neurologic disorders. Severe acute disease in new-born is generally acquired from a symptomatic mother that develop a febrile illness during the last week of pregnancy.

Zika virus and the impact on pregnancy

Since it was first associated with microcephaly and other central nervous system abnormalities, Zika virus infection emerged as a global health issue and discouraged pregnant women from traveling to areas affected by the Zika virus. Zika virus can be transmitted from mother to fetus during pregnancy, and can cause microcephaly, and other congenital malformations, known as congenital Zika syndrome. Microcephaly is determined by loss of brain tissue and abnormal brain development, and the outcome in children may vary, depending on the extent of the damage. Congenital Zika syndrome includes a broad spectrum of malformations, like limb contractions, increased muscle tone, eye abnormalities and hearing impairment. The purpose of this study is to synthesize available information about Zika virus and its impact on pregnancy and fetal development.

Hepatitis C virus infection and pregnancy – not the simplest combination

Hepatitis C virus (HCV) infection has a rather noticeable effect on pregnancy, considering the fact that two entities are involved: the mother and the fetus. It has become a worldwide health threat, so forward actions are to be taken in order to minimize the impact on morbidity and mortality caused by this virus. We conducted this review article based on data from 33 articles published between 2016 and 2021 that assessed both maternal and fetal outcomes, long term effect on children born to HCV infected mothers, screening for HCV among pregnant women, vertical transmission, recommendations for the management of HCV infected pregnant patient, available medication and the need for treating HCV during pregnancy. The majority of authors concluded that HCV has a greater impact on the fetus/child rather than on mother and also, most of them are calling in for the need to treat this infection during pregnancy in order to diminish the risk of vertical transmission, therefore to reduce the incidence of HCV infection among infants. The necessity for further studies, especially on safety data for antiviral medication is imperative, as well as the need for new steps in downsizing the impact of HCV infection on individuals around the globe.

SARS-CoV-2 infection in pregnancy and risk of stillbirth

The COVID-19 pandemic has changed the lives of millions of people across the globe. As of November 2021, WHO has reported more than 250 million confirmed cases of SARS-CoV-2 infection with more than 5 million deaths. Despite the continuous efforts being made by the medical community to address the fundamental questions posed by the SARSCoV-2 infection in pregnant women and its impact over the mother and the offspring. The aim of this paper is to assess the evidence accumulated since the emergence of the pandemic concerning the impact of SARS-CoV-2 infection on the mother and fetus, especially addressing the risks of intrauterine death in SARS-CoV-2 positive mothers. We searched different databases up to November 2021 for variations of the sentence: "SARS-CoV-2 infection and COVID-19 and pregnancy and fetal death, stillbirth, intrauterine death". The changing physiological and immune responses during pregnancy make a pregnant woman more prone to developing severe forms of COVID-19, causing sometimes serious pregnancy complications such as fetal loss. At times mild general symptoms related to COVID-19 can cause serious fetal complications, suggesting that placental changes are responsible for fetal outcome. Infection with non-Delta variant increases the risk of fetal loss in the third trimester two times compared to healthy population, while Delta variant increases this risk four times. The exact mechanism of vertical transmission is still to be established and these aspects need further research especially assessing COVID-19 variant particularities.

Syphilis in pregnancy

Syphilis is a disease caused by Treponema pallidum subspecies pallidum (T. pallidum) through sexual contact or vertical transmission during pregnancy. It is responsible for several hundred thousand stillbirths and neonatal deaths every year worldwide. Prenatal screening for syphilis is critical in order to detect syphilis infection and to prevent congenital syphilis. There are two types of antibodies, treponemal and non-treponemal and two algorithms available for diagnosis. Treatment should be administered according to the stage of syphilis and the antibiotic of choice for pregnant women with syphilis is penicillin G (benzathine penicillin). Non-treponemal antibodies are used for follow-up. There is no vaccination for syphilis that protects both the mother and the fetus. Reducing the incidence of congenital syphilis requires coordinated action involving public health authorities and medical care units.

Prevention of mother-to-child transmission of HIV infection

This review aims to evaluate the prevention strategies of perinatal HIV infections and their efficacy worldwide, both in resource-limited and in resource-rich regions. Furthermore, it presents the most recent aspects of obstetric management of HIV-infected mothers. The introduction of combined antiretroviral therapy (ART) has decreased mother-to-child HIV transmission in high-income settings to historically low levels. Efforts to implement antiretroviral agents in resource-limited countries were also successful in reducing perinatal transmission. However, there are differences in prevention strategies between low and high-resource settings regarding the mode of delivery and infant feeding advice. The three-part prevention strategy (antepartum, intrapartum, and infant prophylaxis) is the most effective approach. Viral load suppression by antiretroviral treatment up to the time of birth is the most effective way to reduce perinatal transmission. Viral load and not HIV status should be used to determine the mode of delivery. Furthermore, the duration of prolonged rupture of membranes is not associated with an increased risk of HIV transmission in women with low viral load. Breastfeeding is contraindicated for mothers living with HIV in resource-rich settings, whereas in low-income areas breastfeeding remains the main nutritional source for infants. ART should be initiated as early as possible in newly diagnosed pregnant women and should be continued for life. Preventive strategies of perinatal HIV transmission have become extraordinarily successful, especially due to the introduction of antiretroviral therapy. Key strategies in the prevention of mother- to-child transmission are prompt identification and treatment of HIV-infected mothers and postpartum infant prophylaxis.

Varicella-zoster virus infection and pregnancy

Varicella-zoster virus is a herpes virus that causes mild to moderate disease when primary infection (chickenpox) is acquired in childhood, but leading to great morbidity and mortality in adults, with even more complications in pregnant women. As a physiologic adaptation in pregnancy that diminishes the possibility of fetal rejection, the altered maternal immune system is the reason why complications are more frequent in this segment of adult population. Moreover, a great concern is represented by the risk of vertical transmission to the fetus that can lead to congenital varicella syndrome (CVS) in the first 2 trimesters or to neonatal varicella if the mother develops the illness perinatally. Antiviral treatment reduces the gravity of the clinical manifestations, but the existent data shows that it doesn’t influence the rate of fetal transmission. Immunoglobulin anti-VZV (VZIG) can be given as prophylaxis when there has been described contact with the virus. Vaccination should be offered to all non-immunized women at the prenatal visit to diminish the maternal and fetal risks in case of subsequent exposure. The purpose of this review is to update the current understanding regarding the best management of varicella infection in pregnancy, based on the latest data from literature and guidelines. An electronic research for relevant reviews and articles published in the last 5 years was made, using PubMed, Medline, Cochrane Data Base, and also the current international guidelines promoted by the Obstetrics and Gynecology Societies in Canada, United States, Ireland and United Kingdom. The importance of prenatal detection of non-immunized women by serologic testing for varicella antibodies should not be overlooked, and subsequent vaccination should be advised to lower the significant complications associated with developing the disease in pregnancy. In case of varicella infection in pregnancy, adequate treatment should be immediately initiated with immunoglobulin and antivirals. Careful follow-up with serial fetal echography should assess if there are abnormalities of fetal development consistent with congenital varicella syndrome. Future mothers need to be advised about the probability of vertical transmission and the associated fetal malformations. Future consideration must focus on identifying the woman at childbearing age at risk and facilitate the vaccination.

HPV and premature delivery risk

Preterm delivery represents the leading cause of perinatal morbidity and mortality. Among possible etiologies of premature birth are the infectious ones, Human Papilloma Virus (HPV) infection being less documented than others. The available data on the role of HPV infection in premature delivery pathogenesis is limited and controversial. This review article attempts to make an assessment of current information on the risk of premature delivery in women with HPV infection during pregnancy. A systematic literature electronic search for journal articles and guidelines regarding HPV infection during pregnancy was undertaken. The relationship between HPV infection and pregnancy is bidirectional, as physiological changes that occur during pregnancy modulate the mechanisms of HPV infection and HPV infection determine adverse maternal, obstetrical, and fetal outcomes.

Viral hepatitis B in pregnancy: A review of its burden, vertical transmission and neonatal prophylaxis

Chronic hepatitis B infection represents a high society burden due to its high morbidity and mortality rate, especially infections acquired by vertical transmission. This review’s purpose is to update information regarding acute and chronic evolution and management of hepatitis B during pregnancy, vertical transmission, and prophylaxis of HBV infection. The database of PubMed was searched for literature reviews, guidelines, and research articles in English, regarding pregnancy and HBV infection from 2015 to October 2021. Pregnancy may have a serious impact on the natural evolution of chronic HBV in cases of advanced disease or liver fibrosis. Management of these patients include periodical monitoring and antiviral therapy during pregnancy. Alanine amino transferase (ALT) flares can occur during pregnancy or more often after birth, being related to the specific immune changes in pregnant women. The most important impact of HBV infection on pregnancy outcomes is represented by vertical transmission. Almost 90% of the infants infected at birth will develop chronic HBV infection out of which 25-40% will develop specific complications. Almost 9% of the newborns of positive HBsAg mothers acquire HBV infection despite standard immunoprophylaxis with hepatitis B vaccine and hepatitis B immune globulin. Failure of immunoprophylaxis can have a higher rate due to elevated levels of HBV DNA during pregnancy, that can be lowered by prophylactic antiviral administration from 28-32 weeks, during pregnancy. Screening every pregnant woman for HBsAg is a good practice measure, which should be standard, among the universal hepatitis B vaccination, in order to achieve a reduction of HBV infection prevalence.

Listeria monocytogenes infection during pregnancy

Listeria monocytogenes is an important pathogenic bacteria found in soil or water being the causative agent of listeriosis, a severe foodborne disease during pregnancy. The outcome can lead up to miscarriage, stillbirth, preterm birth and congenital neonatal infections, under occult or overt illness of the mother. We performed a literature review in the medical database PubMed, searching relevant information regarding listeriosis during pregnancy and neonatal outcome. Higher incidences were observed in ethnic minorities, as a reflection of specific dietary habits and where surveillance is not thoroughly implemented. Also, the infection was most commonly seen during the second or third trimester of pregnancy, with maternal presentation under the form of flu-like or pyelonephritis symptoms, or even asymptomatic. Regarding the neonatal infection, there are two types described according to the way of acquiring the bacteria. The obstetric outcome ranges from premature delivery to miscarriage and stillbirth. Treatment of choice is a combination of ampicillin and aminoglycoside. Despite the advances in the field of infectious diseases, challenges remain to completely understand the mechanism of placental invasion of Listeria monocytogenes and the severe consequences on fetal development.

Toxoplasma gondii infection in pregnancy

Toxoplasmosis is a worldwide spread infection, caused by the parasite Toxoplasma gondii, acquired through ingestion of contaminated food or water, or consuming infected undercooked meat. Despite the fact that in healthy, non-pregnant population, this infection is predominantly asymptomatic and self-limited, in pregnancy it requires special care to minimize the risks to the fetus by vertical transmission. Congenital toxoplasmosis can result in permanent neurological impairment and even blindness. Once diagnosed in pregnancy, this infection needs prompt medical therapy to prevent fetal complications. Primary prevention of the toxoplasmosis consists of dietary and lifestyle changes with the purpose to limit the contact with the parasite. Secondary prevention includes the screening of the pregnant women. Screening programs are implemented in various countries depending on the prevalence of the parasite in the respective areas. The purpose of this article is to make a review of the medical literature concerning the management of Toxoplasma gondii infection in pregnancy. For this purpose, scientific research in databases and online medical publications such as Medline, PubMed, Elsevier and The Lancet was conducted.

Parvovirus infection and pregnancy

Issues regarding parvovirus B19 infection in pregnancy continue to arouse the interest of obstetricians all over the world, the main concern focusing on maternal outcomes and fetal consequences of the intrapartum infection. Parvovirus B19 infection remains one of the main etiologies of fetal anemia and non-immune hydrops, implying a high risk of neonatal demise. This high rate of maternal and neonatal morbidity entails a special attention towards the clinical manifestations and treatment of parvovirus B19 infection during pregnancy time. A systematic literature review was obtained from over 100 articles related to the chosen subject, out of which 27 articles were chosen as relevant to the above-mentioned subject.
