Abstract:
An 88-year-old male patient presented with left ptosis, diplopia, muscle weakness of the lower limbs, dysphagia for solids, dysphonia and constipation. On investigation, he was found to have myasthenia gravis (MG). Further evaluation for the possible cause of MG, with CT scan, revealed that the patient had concomitant prostatic cancer. The patient was given steroids and pyridostigmine, with consequent resolution of his neurological symptoms. This is a rare case of MG associated with prostatic cancer.

Disorders of the Skeletal Muscle
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...

Chemical 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...
