Study Notes
- Muscular dystrophies are genetically inherited disorders affecting muscle strength and function, caused by the absence or deficiency of the protein Dystrophin.
- There are several types of muscular dystrophies, including Duchenne, Becker, and various forms of Limb-Girdle muscular dystrophies.
- Duchenne is the most common and severe form of muscular dystrophy, affecting approximately 1 in 3,500 live male births, while Becker is less severe and affects around 1 in 30,000 individuals.
- Muscular dystrophies can manifest with various symptoms and progression rates, depending on the type. Some types exhibit symptoms in early childhood, while others may be diagnosed later in life.
- Clinical features of muscular dystrophies may include muscle weakness, cognitive impairments, learning difficulties, scoliosis, waddling gait, and cardiomyopathy.
- Diagnosis of muscular dystrophies typically involves a combination of medical history, physical examination, laboratory tests, and genetic testing.
- There is currently no cure for muscular dystrophies, but various treatments can help manage the symptoms and improve quality of life. These include medications, surgical interventions, physical therapy, and assistive devices.
- Nerve entrapment is a condition characterized by chronic compression of a nerve, leading to pain and/or loss of function. Entrapment neuropathies can affect various peripheral nerves, including those in the arms and legs.
- Common symptoms of nerve entrapment include pain, tingling, numbness, weakness, and altered sensation. The specific symptoms depend on the affected nerve.
- Causes of nerve entrapment include traumatic injuries, tumors or cysts, pregnancy hormones, and conditions such as rheumatoid arthritis. A thorough assessment is necessary to determine the underlying cause.
