Manicures, nail polish and remover, nail biting, and repeated trauma such as typing, can contribute to nail splitting. [1] Dehydration likely plays a role. [3] Nutritional deficiencies that can result in nail splitting include iron, selenium, and zinc. [1] Some skin diseases such as psoriasis and lichen planus may feature such nails. [3]
Onychotillomania can be categorized as a body-focused repetitive behavior in the DSM-5 and is a form of skin picking, also known as excoriation disorder. It can be associated with psychiatric disorders such as depressive neurosis, delusions of infestation [2] and hypochondriasis. [3] It was named by Jan Alkiewicz, a Polish dermatologist. [4]
It is believed that there is a temporary cessation of cell division in the nail matrix. This may be caused by an infection or problem in the nail fold, where the nail begins to form, or it may be caused by an injury to that area. Some other reasons for these lines include trauma, coronary occlusion, hypocalcaemia, and skin disease.
Chevron nail, also known as a herringbone nail, is a rare transient fingernail ridge pattern seen in children, a ridge arising from the proximal nailfold and converging in a V-shaped pattern towards the midpoint distally. [1]: 786 The nail growth pattern has no known association with medical problems and tends to resolve by early adulthood. [2]
Tinea cruris is often associated with athlete's foot and fungal nail infections. [4] [5] Rubbing from clothing, excessive sweating, diabetes and obesity are risk factors. [6] [8] It is contagious and can be transmitted person-to-person by skin-to-skin contact or by contact with contaminated sports clothing and sharing towels. [3] [5]
Blisters in particular can cause a feeling of desire to pull or bite off the affected skin and nails (since the skin is dead, thus easily pulled off), which could be detrimental, causing infection. Another disorder, known as excoriation disorder , the repetitive action of uncontrollably picking at one's skin, can sometimes accompany dermatophagia.
Onychorrhexis (from the Greek words ὄνυχο- ónycho-, "nail" and ῥῆξις rhexis, "bursting"), is a brittleness with breakage of finger or toenails that may result from hypothyroidism, anemia, anorexia nervosa or bulimia, or after oral retinoid therapy. [1]: 786 It can also be seen in melanoma that involves the nail and onychomycosis. [2]
They appear as thickened, fissured cauliflower-like skin around the nail plate. Periungual warts often cause loss of the cuticle and paronychia. Nail biting increases susceptibility to these warts. [1] Warts of this kind often cause damage to the nail either by lifting the nail from the skin or causing the nail to partially detach.
