Differential diagnosis of severe pseudohypertrophic malnutrition

Duchenne malnutrition can be divided into Duchenne type and Becker type according to clinical manifestations. Duchenne malnutrition (DMD) is also called severe Duchenne malnutrition. It usually occurs at the age of 4 to 5, usually no later than 7 years old, and usually dies before the age of 20. The following are some symptoms that are easily confused with this disease?

1. Facioscapulohumeral muscular dystrophy

Facioscapulohumeral muscular dystrophy is a hereditary muscle disease that most severely affects the muscles of the face, shoulders, and upper arms. The name FSHD comes from the following three parts: face, which means face in Latin and medical terms; scapula, which means shoulder in Latin and anatomical terms; and humerus, which means the bone from the shoulder to the elbow (the humerus) in Latin and anatomical terms.

2. Muscular dystrophy

Muscular dystrophy refers to a group of genetic diseases characterized by progressive muscle weakness and degeneration of muscles that control movement. Muscular dystrophy includes congenital muscular dystrophy, other BAKER-type MD and other types. Some muscular dystrophy can cause movement impairment or even paralysis. Clinically, it is mainly manifested by progressive skeletal muscle atrophy and weakness of varying degrees and distributions. The myocardium may also be affected.

3. Duchenne muscular dystrophy

Duchenne muscular dystrophy is an X-chromosome recessive genetic disease that mainly occurs in boys. According to statistics, one in every 3,500 newborn boys in the world suffers from this disease. Before school age, patients will experience muscle weakness or atrophy due to the continuous degeneration of skeletal muscles, making it difficult for them to walk.

At about 7 to 12 years old, the child will completely lose the ability to walk, and usually die in his 20s due to myocardial and pulmonary muscle weakness. There is no effective treatment for this disease. Duchenne muscular dystrophy is a disease that endangers people's health.
