Abstract:
The EMG findings of 100 skeletal muscles in 37 cases of thyrotoxicosis are reported. The abnormal short duration motor unit potentials occurred in 78% of examined muscles and in 45% of these muscles, the incidence of polyphasic potentials increased. These abnormalities were in agreement with myopathic lesion exactly. EMG examination is a secure and sensitive method to find impaired muscles. The wide effects of large amount of thyroxin on muscle's metabolism may result in myopathic abnormalities of EMG.

01:15Myasthenia Gravis: Diagnostic Tests
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
