Association of preeclampsia and myasthenia: a case report

Background:
Myasthenia gravis in pregnancy is uncommon, and its occurrence in conjunction with preeclampsia is very rare but may be catastrophic for mother and child.
Case:
A 31-year-old, multiparous woman, with a history of myasthenia gravis and thymectomy, presented at 27 weeks with worsening preeclampsia and delivered by cesarean section under spinal anesthesia. Preeclamptic crisis with hemolysis, elevated liver enzymes and low platelet count (HELLP) syndrome developed postpartum. Blood pressures remained severely high. Intensive care management and a labetalol drip resolved the crisis.
Conclusion:
Added complications may arise from myasthenic exacerbation, difficulties in early recognition of signs and symptoms, and the use of medications that slow neuromuscular transmission.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
01:26Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
