Insights
Congenital insensitivity to pain with anhidrosis (CIPA) is a rare genetic disorder. Early diagnosis and preventive care are crucial to manage complications like self-mutilation and severe injuries.
Area of Science:
- Genetics
- Neurology
- Pediatrics
Background:
- Congenital insensitivity to pain with anhidrosis (CIPA) is an extremely rare genetic disorder.
- CIPA is characterized by the inability to feel pain and a lack of sweating (anhidrosis).
Observation:
- This report details two siblings diagnosed with CIPA at age 2.
- Diagnosis was prompted by recurrent injuries (falls, burns) and severe self-mutilating behaviors, particularly affecting the oro-digital region.
- Nerve biopsy and electromyography confirmed the diagnosis.
Findings:
- CIPA presents with recurrent fevers, anhidrosis, pain insensitivity, and self-mutilation.
- Mental retardation can also be associated with CIPA.
- Complications arising from untreated injuries, such as fractures and mutilations, can be life-threatening.
Implications:
- Management of CIPA is primarily preventive, focusing on avoiding injuries.
- Strict hygiene practices are essential for affected individuals.
- Preventing oro-digital self-mutilation is critical for managing maxillofacial complications.
Introduction:
Congenital insensitivity to pain with anhidrosis (CIPA) is a very rare disorder, most often of genetic origin.
Case Report:
The authors present the case of two siblings, 10 and 13 years old, both followed-up since the age of 2 for CIPA diagnosed after discovering insensitivity to pain during iterative falls, burns, and of severe oro-digital self-mutilating behavior. Sural nerve biopsy and an electromyogram confirmed the diagnosis.
Discussion:
CIPA with anhidrosis is a very rare disease. It is characterized by unexplained fever episodes, anhidrosis, pain insensitivity, self-mutilating behavior, and sometimes mental retardation. Complications of this insensitivity (non-treated fractures, burns, and oro-digital mutilation) may be lethal. Treatment remains preventive. The patient must observe a very strict hygiene. Prevention for maxillofacial involvement consists in breaking the cycle of oral self-mutilation.
