[Clinical, radiological and auxologic long-term evolution of 8 children with asphyxiating thoracic dysplasia]

Area of Science:

• Genetics and rare diseases
• Pediatric medicine
• Medical imaging

Background:

• Asphyxiating thoracic dysplasia (ATD) is a rare skeletal dysplasia.
• Characterized by a narrow thorax, short stature, and limb abnormalities.
• Associated with significant neonatal mortality and multi-organ complications.

Observation:

• This study describes the long-term evolution of 8 pediatric patients diagnosed with ATD.
• Evaluated diagnostic age, sex, anthropometrics, complications, and radiological findings.
• Median age at diagnosis was 2.54 years, with a 6:2 male to female ratio.

Findings:

• All patients (8/8) experienced respiratory compromise.
• Other observed complications included renal (3/8), hepatic (2/8), ophthalmologic (1/8), and cardiac (1/8) impairment.
• Radiological findings consistently showed a narrow chest (8/8) and brachyphalangia (8/8), with acetabular abnormalities in 5/8 patients.

Implications:

• Early recognition of ATD is vital, particularly in newborns with a narrow thorax and respiratory distress.
• Long-term surveillance should include monitoring of renal, hepatic, and ocular functions.
• Understanding the natural history aids in managing multi-organ involvement and improving patient outcomes.
