What is the nail’s function?

Nails protect the sensitive tips of fingers and toes. We don’t need our nails to survive, but they do support the tips of our fingers and toes, protect them from injury, and help us pick up small objects. Without them, we’d have a hard time scratching an itch or untying a knot.

Why koilonychia occurs in iron deficiency?

Koilonychia occurs in 5.4% of the patients with iron deficiency. It is thought to occur due to the upward deformation of lateral and distal portions of pliable iron deficient nail plates under mechanical pressure. Nail matrix changes due to blood flow abnormalities was also proposed as a pathomechanism.

What causes clubbing of the nails?

Nail clubbing occurs when the tips of the fingers enlarge and the nails curve around the fingertips, usually over the course of years. Nail clubbing is sometimes the result of low oxygen in the blood and could be a sign of various types of lung disease.

What are Mees lines?

Mees’ lines (also known as Aldrich or Reynolds’ lines) are transverse white bands on the nail plate laid down during periods of stress. Common associations are poisioning (arsenic, thallium, fluorosis), severe infection, renal disease, cardiac failure, and malignant disease.

Why does koilonychia occur in anemia?

What is eponychium?

Medical Definition of eponychium 1 : the thickened layer of epidermal tissue over the developing fetal fingernail or toenail that disappears before birth except over the base of the nail.

What is the function of free edge?

When the nail plate extends beyond the hyponychium, this becomes the free edge. It is important to have a free edge as this ensures that all the nail bed is covered and therefore protected. The cuticle is the strip of hardened, ‘flakey, dry’ skin found on the nail plate, above the eponychium, at the base of a nail.

Why nails are spoon shaped in anemia?

Spoon nails (koilonychia) are soft nails that look scooped out. The depression usually is large enough to hold a drop of liquid. Often, spoon nails are a sign of iron deficiency anemia or a liver condition known as hemochromatosis, in which your body absorbs too much iron from the food you eat.

What are the respiratory causes of finger clubbing?

Clubbed fingers is a symptom of disease, often of the heart or lungs which cause chronically low blood levels of oxygen. Diseases which cause malabsorption, such as cystic fibrosis or celiac disease can also cause clubbing. Clubbing may result from chronic low blood-oxygen levels.

What is the pathophysiology of clubbing?

Clubbing of the nails is soft tissue swelling of the terminal phalanx resulting in flattening of the angle that exists between the nail bed and the nail. Clubbing typically occurs in combination with other dermatologic and skeletal findings but can also less commonly occur in isolation.

What is COVID toe?

What is the difference between cuticle and eponychium?

The eponychium differs from the cuticle; the eponychium comprises live skin cells whilst the cuticle is dead skin cells. Its function is to protect the area between the nail and epidermis from exposure to bacteria.

What is the function of cuticle or eponychium?

The cuticle, also known as the eponychium, is an extension of the stratum corneum from the proximal nail fold [1-3]. It forms a seal that prevents allergens, irritants, and pathogens from entering the potential space between the distal skin of the digit and the nail plate [4-5].

What is the pathophysiology of koilonychia?

Koilonychia, a concave nail dystrophy, has multiple aetiologies and may be hereditary, acquired or idiopathic. Within dermatology, koilonychia is often a manifestation of an inflammatory dermatosis such as psoriasis or lichen planus, or a sign of onychomycosis.

How do you get rid of koilonychia?
