Although rare, neonatal weakness can present in utero, and mothers may comment on reduced fetal movements. Polyhydramnios can be present as a result of poor fetal swallowing. [mhmedical.com]

Anti-acetylcholine receptor (anti-AChR) antibodies were present in the serum of both mother and child, in umbilical cord serum and in the amniotic fluid. The presence of anti-AChR antibodies in the amniotic fluid may be one of the causes of the NMG. [ncbi.nlm.nih.gov]

• Hypomimia

  The dissociated pattern of neurological disorders (refusal to drink, axial hypotonia, hypomimia, but good contact and normal alertness) led to search for neuromuscular causes or poison. [ncbi.nlm.nih.gov]

  Major akinesia with arthrogryposis and craniosynostosis at birth mimics irreversible disorders of the nervous system of pejorative outcome. [ncbi.nlm.nih.gov]

  The principal mechanism leading to the development of AMC is decreased fetal movements (fetal akinesia), which can result from a large number of both fetal and maternal disorders [ 4 ]. [link.springer.com]

Subsequent workup of the mother revealed myasthenia gravis with muscle-specific kinase antibodies. The infant responded to intravenous immunoglobulin and symptoms normalized. [journals.lww.com]

Edrophonium is primarily but rarely used as a diagnostic tool to predict the response to longer-acting cholinesterase inhibitors (see Workup). [43] AChE inhibitors have a wide variability in the effective dose, depending on the severity and current activity [emedicine.medscape.com]

Selection criteria: We considered randomised controlled trials ( RCTs ) and quasi- RCTs comparing ephedrine as a single or add-on treatment with any other active treatment, placebo, or no treatment in adults or children with autoimmune MG, NMG, or CMSs [cochrane.org]

Reports tend to encourage surgical treatment for the latter group. [emedicine.medscape.com]

Anticholinesterases are used in the treatment. In this study, we present a case diagnosed with transient neonatal MG that has developed intestinal perforation after neostigmine treatment. Key words: Myastenia gravis, neonatal, intestinal perforation [scopemed.org]

In this context, the early detection of anti-acetylcholine fetal receptor antibodies in the mother may allow rapid diagnosis of transient neonatal myasthenia of favorable prognosis. [ncbi.nlm.nih.gov]

False positive rate Muscle specific tyrosine kinase (MuSK-Ab): present in 38-50% of those negative for AchR-Ab. 8-12% of patients are 'seronegative' and have a better prognosis. [pedclerk.bsd.uchicago.edu]

Treatment and prognosis Babies with transient neonatal myasthenia gravis often recover with treatment in a few weeks or months, as maternal autoantibodies disappear on their own. [myastheniagravisnews.com]

The prognosis has improved very much lately due to timely thymus removal and a lot of young women suffering from MG is in clinical remission without medicaments. [myastheniagravis.cz]

Etiology The disorder is related to passive transplacental transfer of maternal anti-acetylcholine receptorantibodies (anti-AChR) or anti-muscle-specific tyrosine kinase antibodies (anti-MuSK) to the neonate. [orpha.net]

Preeclampsia In 1979, Duff described an association between myasthenia gravis and preeclampsia. [17] He observed preeclampsia in 3 patients and reasoned that altered immune status could be an etiologic factor in preeclampsia. [emedicine.medscape.com]

Congenital myasthenia presenting in an infant of non-myasthenic mother is rare (1% of cases). [3] Simpson [10] has postulated an auto-immune etiology of adult myasthenia gravis; but there is no association with thymoma or antibodies in congenital myasthenia [jpgmonline.com]

Ongoing controversies regarding etiology, diagnosis, treatment Although little controversy exists regarding the pathogenesis and diagnosis of MG, there remain questions regarding the benefits of thymectomy beyond medical treatment alone in non-thymomatous [clinicaladvisor.com]
