ICD-10: E00.2

Congenital iodine-deficiency syndrome (CIDS), classified under ICD-10 code E00.2, is a significant health concern that arises from inadequate iodine levels during fetal development. This condition can lead to a range of clinical presentations, signs, symptoms, and patient characteristics that are crucial for diagnosis and management.

Clinical Presentation

CIDS is characterized by a spectrum of developmental and physical abnormalities resulting from iodine deficiency during pregnancy. The severity of the syndrome can vary widely among affected individuals, depending on the degree of iodine deficiency and the timing of exposure during gestation.

Key Features of Clinical Presentation

1. Neurological Impairments:
   - Cognitive deficits, including intellectual disability, are common. Children may exhibit varying degrees of developmental delay, learning difficulties, and behavioral issues.
   - Motor skills may be affected, leading to coordination problems and delayed milestones.

2. Physical Abnormalities:
   - Goiter: An enlarged thyroid gland may be present, although it is not always visible at birth.
   - Dysmorphic Features: Patients may exhibit characteristic facial features, such as a broad, flat nose, thick lips, and a protruding tongue.
   - Short Stature: Growth retardation is often observed, leading to shorter-than-average height in affected individuals.

3. Endocrine Dysfunction:
   - Hypothyroidism is a common consequence of iodine deficiency, which can manifest as lethargy, weight gain, and cold intolerance.

Signs and Symptoms

The signs and symptoms of CIDS can be grouped into several categories:

Neurological Signs

• Intellectual Disability: Varies from mild to severe.
• Delayed Development: Delays in speech and motor skills.
• Behavioral Issues: Increased incidence of attention deficits and hyperactivity.
