All of the following are complications of Duchenne Muscular dystrophy except
**Core Concept**
Duchenne Muscular Dystrophy (DMD) is a severe, X-linked recessive disorder characterized by progressive muscle degeneration and weakness due to the absence or deficiency of dystrophin, a crucial protein for muscle function and integrity. This condition leads to various systemic and musculoskeletal complications, emphasizing the need for comprehensive management.
**Why the Correct Answer is Right**
DMD patients often develop cardiac complications, including dilated cardiomyopathy, leading to heart failure. Additionally, they are at risk for respiratory complications, such as restrictive lung disease and scoliosis, which can further compromise respiratory function. Moreover, DMD patients are prone to endocrine complications, including hypogonadism and growth hormone deficiency.
**Why Each Wrong Option is Incorrect**
**Option A:**
This option is likely incorrect because DMD primarily affects muscles, and while it can lead to secondary effects on other systems, it is not commonly associated with this particular complication. A more typical complication of DMD would be cardiac or respiratory issues.
**Option B:**
This option is incorrect because DMD is not typically associated with the development of osteoarthritis. While joint pain and limited mobility are common in DMD patients, osteoarthritis is not a primary complication of the disorder.
**Option C:**
This option is incorrect because DMD is not typically associated with the development of type 2 diabetes. While DMD patients may experience various metabolic changes due to muscle degeneration and impaired glucose uptake, type 2 diabetes is not a primary complication of the disorder.
**Clinical Pearl / High-Yield Fact**
A key aspect of DMD management is addressing the associated complications, particularly cardiac and respiratory issues, through multidisciplinary care involving cardiologists, pulmonologists, and other specialists.
**Correct Answer: B. Osteoarthritis.**
