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).

Uraemic pruritus (also called chronic kidney disease–associated pruritus) is a persistent itch that occurs in people with advanced kidney disease, particularly those receiving dialysis. The itch can be severe, often worse at night, and commonly affects the back, arms, head, or abdomen, significantly impacting sleep and quality of life.

Nemolizumab is a targeted biologic therapy used in dermatology to treat conditions driven by severe itch, particularly moderate-to-severe atopic dermatitis and prurigo nodularis (pictured). 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.

Erythema multiforme is an immune-mediated skin condition characterised by distinctive “target” or bullseye-shaped lesions that often appear on the hands, feet, and limbs. It is usually triggered by infections (most commonly herpes simplex virus) and is typically self-limiting, although some cases may involve mucous membranes.

Local anaesthesia is the temporary loss of sensation in a specific area of the body, allowing dermatological and surgical procedures to be performed with minimal pain. It works by blocking nerve signals in the skin, and may be applied topically or injected, with lidocaine (lignocaine) being one of the most commonly used agents.
