Half and half nail
Half and half nail
Half and half nail (pronounced: /hæf ænd hæf neɪl/), also known as Lindsay's nail or Lindsay syndrome, is a medical condition characterized by the appearance of the nails. The term "half and half" refers to the distinctive appearance of the nail, which is typically half white (proximal) and half brown or red (distal).
Etymology
The term "half and half nail" is derived from the characteristic appearance of the nail in this condition. The term "Lindsay's nail" is named after Dr. Robert Lindsay, who first described the condition in 1967.
Symptoms
The primary symptom of half and half nail is the distinctive appearance of the nails. The proximal portion of the nail (closest to the nail root) appears white or pale, while the distal portion (furthest from the nail root) appears brown or red. This condition is typically bilateral, affecting both hands.
Causes
Half and half nail is often associated with chronic kidney disease (CKD). However, it can also occur in individuals with liver disease, malnutrition, or hyperthyroidism.
Diagnosis
Diagnosis of half and half nail is primarily based on the characteristic appearance of the nails. Additional tests may be conducted to determine the underlying cause, particularly if kidney disease is suspected.
Treatment
Treatment for half and half nail primarily involves addressing the underlying cause. For example, if the condition is associated with kidney disease, treatment may involve dialysis or kidney transplantation.
