Onychomadesis
“Today, let’s look into ‘onychomadesis’, a condition that affects your nails, which can occur after suffering from hand-foot-and-mouth disease. In a pediatric clinic, an average of 3.8 weeks after the onset of the disease, five patients under the age of four were diagnosed with changes in their nails.
The symptoms observed were a separation of the nail plate and the nail bed, and horizontal ridges, as shown in the picture. Without any special treatment, all patients’ normal nails grew back while being observed over time.
The Beau’s lines, which are horizontal ridges that occur when nail bed proliferation temporarily stops or decreases, and onychomadesis, which is when the nail plate splits vertically, can occur after severe systemic diseases, stress, medication, trauma, Kawasaki disease, and viral infections such as hand-foot-and-mouth disease.
In particular, these changes in the nails are thought to occur when the virus proliferation after such viral infections damages the nail bed, resulting in conditions like #onychomadesis or #Beau’s_lines. These changes in the nails are temporary and recover to normal growth spontaneously within 1-4 months without any special treatment.
Today, we have looked into ‘onychomadesis’, a change in nails that can occur after viral infections such as hand-foot-and-mouth disease and Kawasaki disease. To put it simply, when the ‘factory’ that produces nails temporarily fails to function due to viruses, systemic diseases, stress, medication, etc., layers form in the nails, similar to layers forming in the stratum. Most cases are temporary and naturally improve.”
