[Congenital insensitivity to pain]

Area of Science:

• Neurology
• Genetics
• Rare Diseases

Background:

• Congenital insensitivity to pain (CIP) is a rare group of hereditary sensory neuropathies (HSN).
• CIP is characterized by the inability to perceive pain, leading to unnoticed injuries and secondary complications.
• This report focuses on the therapeutic challenges encountered in three siblings diagnosed with CIP.

Observation:

• Three siblings were diagnosed with congenital insensitivity to pain between the ages of 3 and 5.
• All siblings experienced fractures of the lower limbs, which were diagnosed late, resulting in malunion and deformities.
• The oldest sibling developed severe complications including hip luxation, sepsis, and required surgical interventions like femoral head resection.

Findings:

• Late diagnosis of fractures in children with CIP leads to significant orthopedic complications and deformities.
• Severe systemic infections, such as sepsis, can arise from untreated injuries in individuals with CIP.
• Current medical understanding lacks a causal treatment for CIP, emphasizing the need for patient education and injury prevention.

Implications:

• There is a critical need for early diagnosis of congenital insensitivity to pain to prevent severe orthopedic and systemic complications.
• Patient education on avoiding mechanical and thermal trauma is paramount for managing CIP and preventing life-threatening conditions.
• Further research into potential causal treatments for hereditary sensory neuropathies is warranted to improve patient outcomes.
