Abstract
Myasthenia gravis (MG) is an autoimmune condition, that commonly impacts adult women of reproductive age. Myasthenia gravis in pregnancy is rare, but the incidence is higher in different geographical areas. Pregnancies in mothers with MG can have an unfortunate outcome. Acetylcholine receptor antibodies may pass into the fetal circulation and can affect the fetal neuromuscular junction, generating transient MG or even fetal arthrogryposis. The 2016 and 2021 International Consensus Guidance for Management of Myasthenia Gravis issued by Myasthenia Gravis Foundation of America is lacking in recommendation for fetal surveillance for pregnancies in women with MG. The aim of this paper is to highlight fetal and neonatal complications in mothers with MG and to offer antenatal care insights. Close maternal and pregnancy monitoring can improve pregnancy outcome. Patients with MG should be encouraged to conceive, to avoid triggers for exacerbations of the disease during pregnancy and a multidisciplinary team should be established to ensure the optimal support and therapy.

Abstract
INTRODUCTION Myasthaenia gravis (MG) is the most common disease of the neuromuscular junction; clinical presentation of the disease includes a variety of symptoms, the most frequent beign the only ocular muscles involvement, to the generalized myasthenic crisis with diaphragmatic impairment and respiratory insufficiency. It is most common in women between 20 ad 40 years. EVIDENCE ACQUISITION We performed a comprehensive search of relevant studies from January1990 to Dicember 2019 to ensure all possible studies were captured. A systematic search of Pubmed databases was conducted. EVIDENCE SYNTHESIS Pregnancy has an unpredictable and variable effect on the clinical course of MG; however, a stable disease before is likely not to relapse during pregnancy. exacerbations can still occur more often during the first trimester and the post partum period. The transplacental passage of antibodies results in a neonatal transient disease, whereas the major concern is related to foetal malformations such as fetal arthrogryposis and polyhydramnios. The overall neonatal outcome described in literature is variable, perinatal mortality in women with MG is generally the same as non affected patients, although in one study the risk of premature rupture of the membranes was higher. Treatment of MG in pregnangncy includes pyridostigmine and corticosteroids, although the latter have been associated with higher risk of cleft palate, premature rupture of the membranes and preterm delivery. These drugs appear also to be safe in breastfeeding. In MG patients spontaneous vaginal delivery should be encouraged, for surgery could cause acute worsening of myasthenic symptoms; also an accurate anesthesiological evaluation must be performed prior to both general and local anesthesia due to increased risk of complications. CONCLUSIONS Most of the myasthenic women could have uneventful pregnancy with good obstetrical outcomes, both for mother and neonate. However, a careful planning of pregnancy and multidisciplinary team approach, composed by neurologists, obstetricians, neonatologists and anesthesiologists, is required to manage these pregnancies.

Abstract
Maternal passage of immunoglobulin G (IgG) is an important passive mechanism for protecting the infant while the neonatal immune system is still immature and ineffective. IgG is the only antibody class capable of crossing the histological layers of the placenta by attaching to the neonatal Fc receptor expressed at the level of syncytiotrophoblasts, and it offers protection against neonatal infectious pathogens. In pregnant women with autoimmune or alloimmune disorders, or in those requiring certain types of biological therapy, transplacental passage of abnormal antibodies may cause fetal or neonatal harm. In this review, we will discuss the physiological mechanisms and benefits of transplacental transfer of maternal antibodies as well as pathological maternal situations where this system is hijacked, potentially leading to adverse neonatal outcomes.

Abstract
Myasthenia gravis is an autoimmune disorder characterized by fluctuating weakness of extraocular and proximal limb muscles. It occurs in 1 in 5000 in the overall population and is 2 times more common in women than men. The onset in women is most common in the third decade, and risk of severe exacerbation occurs most frequently in the year after presentation. The disease does not have an impact on fertility and overlap with pregnancy is expected. This article provides a description of the disease process and its impact on the expecting mother, fetus, and newborn. Management options in pregnancy and lactation are discussed.

Abstract
Myasthaenia gravis (MG) is an autoimmune neuromuscular disorder which is twice as common among women, often presenting in the second and third decades of life. Typically, the first trimester of pregnancy and first month postpartum are considered high-risk periods for MG exacerbations. During pregnancy, treatment for MG is usually individualised, thus improving its management. Plasma exchange and immunoglobulin therapies can be safely used to treat severe manifestations of the disease or myasthaenic crises. However, thymectomies are not recommended because of the delayed beneficial effects and possible risks associated with the surgery. Assisted vaginal delivery-either vacuum-assisted or with forceps-may be required during labour, although a Caesarean section under epidural anaesthesia should be reserved only for standard obstetric indications. Myasthaenic women should not be discouraged from attempting to conceive, provided that they seek comprehensive counselling and ensure that the disease is under good control before the start of the pregnancy.

Abstract
Although rare, the co-occurrence of myasthenia gravis and preeclampsia during pregnancy is responsible for considerable maternal and foetal morbidity and mortality. Both careful selection of medications and a multidisciplinary approach are required for treating such cases. This study presents a case report of a patient with a known history of generalized myasthenia gravis who presented with preeclampsia at 33 weeks' gestation. Subsequently, the patient developed recurrent seizures that necessitated the use of multiple medications, including phenytoin, valproic acid, levetiracetam, and propofol. Magnesium sulphate was not administered due to its blocking effect on calcium channels at the neuromuscular junction. The patient underwent a caesarean section under spinal anaesthesia and gave birth to a baby with intrauterine growth restriction (IUGR). Blood pressure control was achieved with the administration of methyldopa and parenteral hydralazine, an increased dose of pyridostigmine, and intravenous immunoglobulin therapy. The status of the patient's myasthenia gravis remained stable. This case serves to highlight the conflicts in the management of these two disorders and suggests strategies to resolve these conflicts in clinical management.

Abstract
Myasthenia gravis is an acquired, autoimmune neuromuscular disorder characterized by voluntary muscle weakness. Pregnant patients may have disease exacerbation, respiratory failure, crisis, adverse drug reaction, surprisingly enough remission at any trimester or postnatal period. Concurrence of myasthenia gravis with severe preeclampsia is a dreadful condition raising diagnostic and management issues. We hereby discuss a case of myasthenic woman who developed severe preeclampsia during pregnancy and presented in last trimester with clinical features mimicking signs of impending eclampsia. Keeping in mind the history of myasthenia gravis, urgent neurology review taken and diagnosis of myasthenic exacerbation was entertained. She responded well to injection neostigmine and in this way inadvertent use of magnesium sulphate was avoided.

Abstract
Myasthenia gravis (MG) is a chronic autoimmune neuromuscular disease and is the most common disorder of neuromuscular transmission. MG is caused by a defect in the transmission of nerve impulses to muscles in which communication from nerves to muscles is interrupted at the neuromuscular junction. This interruption can cause significant impact to muscle functions, which can have serious consequences for a pregnant woman, especially during labor. This brief article, which is meant to be used as an easy-reference tool in the clinical setting, examines the disease process and its effect on the antepartum, intrapartum and postpartum periods.

Abstract
Myasthenia gravis is a chronic autoimmune disease of neuromuscular transmission resulting in fatigable skeletal muscle weakness. Preeclampsia is a multisystem disease of pregnancy which is characterised by hypertension and involvement of one or more organ systems. Both diseases are responsible for considerable morbidity and mortality for mother and fetus. The occurrence of both preeclampsia and myasthenia gravis in pregnancy is very rare, and conflicts arise when considering the optimal management of each disease.We present a case of a parturient who was newly diagnosed with both myasthenia gravis and preeclampsia in late pregnancy. Myasthenia treatment was started with prednisolone and pyridostigmine, and delivery was by caesarean section at 37 weeks gestation under spinal anaesthesia. Postnatally, the patient developed worsening of myasthenia and preeclampsia symptoms. We consider the anaesthetic implications for both diseases and describe our approach for the management of this case.

Abstract
Glucocorticoids (GC) are the most commonly used immune-directed therapy in myasthenia gravis (MG). However, to date, GC have not proven their effectiveness in the setting of a randomized clinical trial that complies with currently accepted standards. The rationale for the use of GC in MG is the autoimmune nature of the disease, which is supported by consistent positive results from retrospective studies. Well-defined recommendations for treatment of MG with GC are lacking and further hampered by inter- and intra-individual differences in the disease course and responses to GC treatment. Uncertainties concerning GC treatment in MG encompass the indication for treatment initiation, exact dosage, dose adjustment in specific conditions (e.g., pregnancy, thymectomy), mode of tapering, and surveillance of adverse events (AE). This review illustrates the mode of action of GC in the treatment for MG, presents the currently available data on GC treatment in MG, and attempts to translate the currently available information into clinical recommendations.

Abstract
Myasthenia gravis is an autoimmune disease of the neuromuscular junction characterized by painless fluctuating skeletal muscle weakness. Disease exacerbations are more likely to occur in the first trimester or puerperium. A number of medications commonly used in obstetric practice can exacerbate the disease. The effect of pregnancy on myasthenia varies substantially from woman to woman and also from pregnancy to pregnancy in the same woman. Mainstay treatments involve acetylcholine esterase inhibitors, corticosteroids and other immunosuppressants, and adequate rest. Newborns may suffer in utero or neonatal consequences, usually transient, of transplacental antibody exposure.

Abstract
BACKGROUND AND OBJECTIVE Myasthenia gravis is an autoimmune neuromuscular disease, usually affecting women in the second and third decades. The course is unpredictable during pregnancy and puerperium. Myasthenia gravis can cause major interference in labour and partum and exacerbations of the disease frequently occur. The aim of this series of cases is to analyse retrospectively the anaesthetic management of myasthenia gravis patients and complications during the peripartum period. MATERIALS AND METHODS Retrospective, single centre study from clinical files of female myasthenia gravis patients who delivered between 1985 and 2007 at Hospital de Santo António, Porto, Portugal. RESULTS Seventeen myasthenia gravis patients delivered between 1985 and 2007 in Hospital Santo António. Two women were not included in the study as they had a spontaneous abortion in the first trimester. Four patients presented exacerbations of the disease during pregnancy, no exacerbation occurred in eight patients and three patients presented their first symptoms of myasthenia gravis during pregnancy (without diagnosis at time of delivery). Concerning the eight patients without exacerbations of the disease during pregnancy, pregnancy was brought to term in 87.5% of the cases; five women were submitted to nonurgent caesarean section (62.5%); and epidural block was performed in six patients (75%). No complications related to anaesthesia occurred in the peripartum period. Concerning the four patients with exacerbations of the disease, pregnancy was brought to term in three cases (75%); three women were submitted to nonurgent caesarean section (75%); and epidural block was performed in three patients (75%). One patient underwent an uncomplicated thymectomy under general anaesthesia during pregnancy and, in the postpartum period, there was a myasthenic crisis in another patient. Concerning the three patients without a myasthenia gravis diagnosis at partum, one woman already being followed for presenting muscular weakness had a vaginal delivery under epidural block, without complications; another patient, presenting discrete supine dyspnoea, was submitted to elective caesarean section under spinal block and developed severe dyspnoea that required mechanical ventilation and ICU admission; and in the remaining case, a woman presenting mild blurred vision was submitted to general anaesthesia, which resulted in delayed emergence, muscular weakness and respiratory failure. Pregnancy went full term in all cases (100%). No newborn had a myasthenic crisis. CONCLUSION Myasthenia gravis can interfere slightly with pregnancy and partum, although exacerbations of the disease occur frequently. Strict surveillance and therapeutic optimisation are crucial. In women with controlled disease, caesarean section should be carried out only if there are obstetric reasons. Locoregional anaesthesia is preferred, mainly epidural block. A good multidisciplinary cooperation, specific precautions and surveillance can certainly contribute to an improved outcome in myasthenia gravis patients during the peripartum period.

Abstract
This case describes an apparently healthy 21-year-old parturient who presented at term with a prolapsed cord requiring immediate cesarean section. She experienced postoperative seizures. After a presumptive diagnosis of eclampsia, magnesium sulfate was given. During a complicated postoperative course, ventilatory failure necessitating multiple intubations eventually led to a new diagnosis of myasthenia gravis. This report describes how the signs and symptoms of myasthenia gravis may mimic post-partum eclampsia as well as worsen the side effects of magnesium therapy.

Abstract
Myasthenia gravis (MG) is a chronic autoimmune disorder of neuromuscular transmission characterized by varying degrees of weakness and easy fatigability of the skeletal muscles. Precipitants of myasthenic symptoms or crises include physical and emotional stress, systemic illness, infections, hypo or hyperthyroidism, pregnancy, any type of surgery with general anaesthesia as well as corticosteroids. The authors report two cases of MG in pregnancy and discuss briefly the various aspects of the disease course and management in pregnancy. As MG occurs predominantly in women of reproductive years, it is important that obstetricians are aware of this condition and its management in pregnancy.

Abstract
BACKGROUND Neurologic dysfunction, coma, and seizures are common in obstetric patients in the intensive care unit. OBJECTIVE To review common neurologic disorders resulting in critical illness in pregnancy. REVIEW Obstetric disorders causing coma and seizures include eclampsia, acute fatty liver of pregnancy, and amniotic fluid embolism. Preexisting disorders such as epilepsy may worsen in one-third of pregnant patients, and seizures are common during labor. Changes in hemodynamics, blood volume, and hormonal effects on the vessel wall increase risk of bleeding from berry aneurysms and arteriovenous malformations during pregnancy and the postpartum period. Acute intermittent porphyria produces seizures and hypertension, closely mimicking eclampsia. Cerebral venous sinus thrombosis is common in postpartum patients, especially in developing countries. Brain tumors invariably enlarge during pregnancy because of fluid retention and the presence of estrogen and progesterone receptors on tumor cells. Infections such as cerebral malaria and acute viral hepatitis with fulminant hepatic failure are common causes of coma and seizures during pregnancy in tropical regions of Asia, Africa, and Latin America. Patients may be admitted to the intensive care unit with type II respiratory failure due to myasthenic crisis, Guillain-Barre syndrome and spinal cord disease. Relapses of multiple sclerosis are infrequent during pregnancy but increase in the postpartum period. CONCLUSIONS In all instances, the effects of the disorders, diagnostic tests, and treatment on the fetus must be carefully weighed. Prompt delivery may be lifesaving for mother and fetus in conditions such as eclampsia and acute fatty liver of pregnancy; expectant treatment may be more appropriate in others.
