Descrição
Centronuclear myopathy is a condition characterised by muscle weakness (myopathy) and wasting (atrophy) in the skeletal muscles, which are the muscles used for movement. The severity of centronuclear myopathy varies among affected individuals, even among members of the same family.
People with centronuclear myopathy begin experiencing muscle weakness at any time from birth to early adulthood. The muscle weakness slowly worsens over time and can lead to delayed development of motor skills, such as crawling or walking; muscle pain during exercise; and difficulty walking. Some affected individuals may need wheelchair assistance as the muscles atrophy and weakness becomes more severe. In rare instances, the muscle weakness improves over time.
Some people with centronuclear myopathy experience mild to severe breathing problems related to the weakness of muscles needed for breathing. People with centronuclear myopathy may have droopy eyelids (ptosis) and weakness in other facial muscles, including the muscles that control eye movement. People with this condition may also have foot abnormalities, a high arch in the roof of the mouth (high-arched palate), and abnormal side-to-side curvature of the spine (scoliosis). Rarely, individuals with centronuclear myopathy have a weakened heart muscle (cardiomyopathy), disturbances in nerve function (neuropathy), or intellectual disability.
A key feature of centronuclear myopathy is the displacement of the nucleus in muscle cells, which can be viewed under a microscope. Normally the nucleus is found at the edges of the rod-shaped muscle cells, but in people with centronuclear myopathy the nucleus is located in the center of these cells. How the change in location of the nucleus affects muscle cell function is unknown.

Can I take Atorvastatin and Milk thistle extract together?
Taking milk thistle with atorvastatin might increase the levels of the medication in your bloodstream. This could potentially increase the risk of side effects, such as muscle aches, pain, or weakness (a condition called myopathy). Caution is advised when taking atorvastati and milk thistle together. Combining them may increase the amount of.

Posso tomar Atorvastatina e Piridostigmina juntos?
There is a potential for increased muscle-related side effects when taking these two medicines together. Both drugs can independently affect muscle function; atorvastatin can cause muscle aches or weakness (myopathy), e pyridostigmine is used to treat fraqueza muscular in conditions like myasthenia gravis. Taking them together might make it harder.

Posso tomar Amlodipina e Atorvastatina juntos?
Taking amlodipine and atorvastatin together can increase the amount of atorvastatin in your blood. This may increase the risk of side effects, particularly tensão muscular pain, tenderness, or weakness (a condition called myopathy). In rare cases, this can lead to a more serious muscle breakdown called rhabdomyolysis. Amlodipine and atorvastatin can.
