TERRY'S NAILS

The nail looks opaque and white, but the nail tip has a dark pink to brown band.

May accompany cirrhosis, congestive heart failure, adult-onset diabetes, cancer or ageing.

ECZEMA OF THE NAIL

It affect the eponychium, nail plate and bed It causing pitting and onycholysis.

This is very rare

Eczema

HANG NAILS

Caused by minor injury or constant irritation through biting. The cuticle splits and appears as a small spike.

Hot oil manicures and regular use of a cuticle oil will help.

The spike can be clipped so it does not catch on things.

EGGSHELL NAIL

Nail plate is thin and abnormally flexible

chronic illness of systematic or nervous origin

It curves at the free edge and the nail plate can separate from the nail bed

ONYCHOLYSISDISTAL OR LATERAL SEPARATION OF NAIL FROM NAIL BED

Psoriatic onycholysis considered as a reference point for other forms

PO-typically distal,variable lateral involvement,area of separation appear white or yellow due to air beneath the nail,sequestered debris & glycoprotien exudate

Isolated islands of onycholysis present as Oil spots , salmon patches

ONYCHOLYSIS

Idiopathic-Painless separation of nail

from its bed-Overzealous manicure,wetting,cosmetic solvents-Condition starts at tip of

nail,spreads to distal one third of nail bed

-Colonization of candida albicans & pseudomonas pyocyanea

-Affected nails grow very quickly,more in women,

Secondary Psoriasis,trauma,funga

l infections,dermatitis,hypothyroidism,yellow nail syndrome,shell nail syndrome

- Photoonycholysis : treatment withpsoralens,doxycycline,demethylchlortetracycline,retinoids,anti cancer drugs

ONYCHOLYSIS

Distal onycholysis Loss of cuticle Psoriasis may be

cause

ONYCHOLYSIS

Most commonly associated with external trauma to the nail

Nail plate separates from the nail bed

ONYCHOLYSIS

The subungual space may be filled with hyperkeratotic debris

Distal nail bed separated from the nail plate in 2 nails.

ONYCHOLYSIS

Treatment : Patient advised cut away loosened nail &

apply local steroid with antibiotics ( prevent keratinisation of nail bed,that slows reattachment of nail)

Gentamicin eye drops for pseudomonas infection

2% thymol in chloroform for preventing infection

Milton regimen : soaking finger tips several nights week in venegar or sodium hypochlorite solution for 5 mins for prevention of recurrence

ONYCHOMYCOSIS A fungal or yeast infection which results in

Onychomycosis, can  invade through a tear in the proximal and lateral nail folds as well as the eponychium. 

This type of infection is characterized by onycholysis with evident debris under the nail plate.

It normally appears white or yellowish in color, and may also change the texture and shape of the nail.

The fungus digests the keratin protein of which the nail plate is comprised.  As the infection progresses, organic debris accumulates under the nail plate often discoloring it.If left untreated, the nail plate may separate from the nail bed and crumble off.

ONYCHOMYCOSIS(TINEA UNGUIUM)

White spots that can be scraped off the surface, or long yellowish streaks within the nail substance.

It attacks the free edge & moves towards the matrix

ONYCHOMYCOSIS

TINEA UNGUIUM – NAIL INFECTION

ONYCHOMYCOSIS

DSO

Distal subungual

hyperkeratosis and onycholysis involving most of the nail bed

of the great toenails; these

findings are usually

associated with tinea pedis.

Onychomycosis

ONYCHOMYCOSIS

NAIL CLIPPINGS SHOW SEPTATE HYPHAL ELEMENTS PROVEN TO BE TRICHOPHYTON SP WITH IN NAIL PLATE KERATIN

90 % Toe nail infections with Trichophyton,Microsporum,Epidermophyton sp

PAS staining most sensitive test

Stain reveals fungal organisms located in lower stratum corneum

Distal subungual Onychomycosis is MC form,caused by T.rubrum

It invades hyponychium & LNF finally yellow,onycholysis,sub ungual hyperkeratosis

T.mentagrophytes identified in superficial white OM,located in superficial nail plate

ONYCHOPHAGY

Bitten nails, often no free edge is visible

Nails look ragged and distorted

skin and nail bed can be exposed and raw

ONYCOPHOSIS

Refers to the growth of the horny epithelium in the nail bed

In other words a callus like growth on the nail plate

ONYCHOGRYPHOSIS

Elderly,Commonly toenails,usually Hallux

Favored by trauma Impairement of peripheral circulation

and innervation Nail acquires typical Ram’s Horn

shape d/t asymmetric growth Thick,hard,yellow brown nails

ONYCHOPTOSIS

Periodic shedding of one or more nails, either in whole or parts

This condition may follow certain diseases such as syphilis

PARONYCHIA

Paronychia is associated with separation of the seal between the proximal nail fold and the nail plate that provides entry for bacteria and leads to a localized infection of the paronychial tissues of the hands.

Symptoms may include inflammation, swelling & scaling

PARONYCHIA

An infectious and inflammatory condition of nail folds. Infection is bacterial

Ch paronychia may weaken defences and increase the risk of developing a fungal infection of the nail

PARONYCHIA

The nail fold is

erythematous, edematous,

with early abscess

formation, and is very

painful.

Paronychia

PTERYGIUM

Pterygium is the inward advance of skin over the nail plate,

Usually as a result of trauma to the matrix due to a surgical procedure or by a deep cut to the nail plate

Pterygium results in the loss of the nail plate due to the development of scar tissue 

Cortisone is used to prevent the advancement of scar tissue.  Never attempt to remove pterygium -instead, consult a physician for advice and treatment

NOTE: The 'true cuticle' is often referred to as Pterygium

PTERYGIUM Pterygium Inversum Unguis is an

acquired forward growth of the hyponychium characterized by live tissue firmly attached to the underside of the nail plate, which contains a blood supply and nerves. 

Possible causes are systemic,

hereditary, or from an allergic reaction to acrylics or solvents. 

Never use force to 'push back' the advancing hyponychium -- it is an extremely painful approach, and will result in a blood flow. 

PTERIGIUM

An abnormal winged like growth of skin (living tissue) on the nail plate

The skin is slowly stretched and dragged along the bed

caused by severe trauma such as warts, burns & blood circulation disorders.

PTERYGIUM

DORSAL PTERYGIUMVENTRAL PTERYGIUM

SCABIES OF NAIL

Commonly identified in crusted scabies Heaped up masses of keratin

accummulate underneath the nail Subungual material contains abundant

mites,source of infection Nails become dystrophic

SCABIES OF NAIL

SCABIES OF NAIL

Sarcoptes scabiei present in distal subungual hyperkeratotic debris found in hyponychium

Cause of persistent epidemics of scabies

Norwegian scabies severe involvement of nail folds

Scrapings of distal hyponychium- showing organism – Sarcoptes Scabiei

CANDIDA

Candida parapsilosis account for 20% infections

Candida common cause of Chronic paronychia,involve nail bed & nail plate in HIV

Candida albicans major cause of hypertropic nail bed infection in paediatric patients with HIV

CANDIDAL PARONYCHIA

MUCOCUTANEOUS CANDIDIASIS

CANDIDA

NAIL CLIPPINGS SHOW BUDDING YEASTS

PSEUDOMONAS

Pseudomonas bacterial infection can occur between the natural nail plate and the nail bed

Many people have been led to believe that the classic 'green' discoloration of this type of infection is some type of mold

In actuality, mold is not a human pathogen.  The discoloration is simply a by-product of the infection and is caused primarily by iron compounds

PSEUDOMONAS

Pseudomonas thrive in moist places; it feeds off the dead tissue and bacteria in the nail plate, while the moisture levels allow it to grow

The after effects of this infection will cause the nail plate to darken and soften underneath an artificial coating

PSEUDOMONAS

The darker the discoloration, the deeper into the nail plate layers the bacteria has traveled.  If the bacteria has entered between the nail plate and the nail bed, it will cause the same discolorations and may also cause the nail plate to lift from the nail bed.

PSEUDOMONAS

pseudomonas colonisation

ALOPECIA AREATA

First sign in 18% cases,More in children Pitting of nails,When pits uniformily

distributed on multiple nails,they often arranged in lines horizontially or vertically in a geometrical design k/a Glen-Plaid or Scotch-Plaid Pattern
