Pictured from left to right:
- Woolly hair from birth
- Striate keratoderma of the palms
- Marked hyperkeratosis over pressure areas on the feet
- Plantar keratoderma of the soles

This combination is classic for Naxos disease - a rare genetic cardiocutaneous syndrome. 💡 Key clue: Early hair changes + palmoplantar keratoderma should prompt consideration of an underlying cardiac condition (arrhythmogenic cardiomypathy).

It works by blocking the IL-31 receptor, a key pathway involved in chronic itch and skin inflammation, helping reduce pruritus and improve skin symptoms.

Bed bugs are small blood-feeding insects that typically bite exposed skin during sleep, often causing itchy red bumps that may appear in clusters or a line- sometimes called the “breakfast, lunch, and dinner” pattern. Interestingly, up to 70% of people may have little or no reaction to the bites, making infestations difficult to recognise.
