Earlier manifestation of Rickets is –
**Core Concept**
Rickets is a disease caused by a lack of vitamin D, calcium, or phosphate. It leads to softening and weakening of the bones in children, resulting in skeletal deformities. The manifestations of rickets can vary depending on the age of the child and the severity of the disease.
**Why the Correct Answer is Right**
The correct answer is related to the early signs of rickets, which can be subtle and nonspecific. In young children, rickets may present with irritability, failure to thrive, and muscle weakness. As the disease progresses, more obvious signs such as bowing of the legs, delayed closure of the fontanelles, and widening of the wrists and ankles may become apparent. The earlier manifestation of rickets is often related to the child's overall health and growth, rather than the classical skeletal deformities.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately represent the early signs of rickets. While some children with rickets may experience pain, it is not a universal symptom and is often a late manifestation of the disease.
**Option B:** This option is incorrect because it is a symptom of advanced rickets, rather than an early manifestation. Delayed closure of the fontanelles is a sign of increased intracranial pressure, which can occur in severe cases of rickets.
**Option C:** This option is incorrect because it is a symptom of advanced rickets, rather than an early manifestation. Widening of the wrists and ankles is a sign of skeletal deformity, which can occur in late-stage rickets.
**Clinical Pearl / High-Yield Fact**
Rickets can be prevented with adequate vitamin D supplementation, particularly in children who are breastfed or have limited sun exposure. Vitamin D is essential for calcium absorption and bone mineralization, and a deficiency can lead to rickets.
**Correct Answer:** A.
