• Anatomy and physiology :
1. Dermis: consists largely of fibroblasts
2. Sebaceous gland: are active at birth
due to influence of maternal hormone
3. Apocrine glands: become functional
around 8-10 years
Skin disease in children may be due
to any of the following:
• Bacterial infection: as impetigo
contagiosa or cellulitis
• fungus: as Candida
• Skin Parasites: in scabies or
pediculoses
A-Bacterial infection: 1- (impetigo contagiosa)
• It is a highly contagious superficial skin
bacterial disease (staphylococcus aureus,
bacteria hemolytic streptococci)
• IT characterized by localized inflammation and
infection in epidermis
• There is two major disease cause impetigo
1-characterized by crusted lesion
2-characterized by fragile bulla( brown shriner)
Incidence and Etiology
• It is more prevalent during mid to
late summer& humid climate
• Peak incidence among children 2-6
years,
• Causes :
• poor sanitation
• It most commonly spread by direct
contact
Clinical manifestations
• Lesion that begin as small red macules and
progress to small, thin vesicles or pustules
that rupture easily and exposed weeping
.The crusts fall &no traces.
• Systemic symptoms such as : weakness,
fever & diarrhea
• It appear in the face, around the mouth
• Pruritus is associated with child scratches
Treatment and Nursing
Management
• Eliminating the causative organism:
1- By topical antibiotic therapy in case of
few lesions
2-If lesion wide spread or don’t respond,
administer oral systematic antibiotics.
3-Nursing Assessment :
Observe for presence of high temp,
respiratory rate, heart rate, dermatitis,
lymphadenopathy .
• Teach the care giver to :
1. Prevent the spread of infection &
complication& isolate the child
2. Careful hand washing before and after
contact with the child
3. Ask the child to don’t touch the lesion
when awake
4. Use comfort measure :
-such as genital soaking & remove the
crust with warm soapy water.
-Keep the child nail cut short
2-Cellulitis
• Cellulites : is a bacterial infection involving the
dermis and subcutaneous gland
• Incidence and Etiology:
-occur at any age
-1-2 days following trauma that disrupt the skin
-Streptococcus pyogenes &staphylococcus
-children with cellulites of head have incident of
trauma
Path physiology :bacteria inter the skin ,
after minor trauma
infection in connective tissue
Clinical manifestation
• Erythema, swelling, warmth, and pain
• Lymphangitis , lymphadenopathy,
• Systemic symptoms as: fever, chills,
malaise
• Child with facial erythema due to
influenza type B are at risk for
meningitis
Treatment& Nursing
management
•
•
Systemic antibiotic
Hospitalization in case of febrile &
acutely ill & use IV antibiotic
• COMFORT Measure:
1. Warm compresses to increase circulation
2. Cold compresses used to relive pain
•
Immobilization is recommended for
comfort and decrease edema
B-Fungal infection
• The body has several defense
mechanisms:
1. Nutritional status
2. General health
3. Skin properties: as PH, Rate of
epithelial turn over inhibit fungal
infection
1-Candidiases
• Candidiases & moniliases are the most
common type of infection
• Candida albicance a commensally fungal
of the mouth & gastroenteritis
• It exist in 2 form yeast and spore
• Incidence and Etiology:
• Incidence of thrush in infant 2-4%
candidiasis
Candidia diaper
• Etiology :
A-Causes related to child :Alteration in immune
system & from vaginal canal& bottle nipple
• Use of antibiotic therapy &endocrine disease &
immunosuppressive therapy
• Child with anemia &asthma (corticosteroid)
B-Causes related to diaper:
• have macerated mucous membrane
• Improper use of diaper
• Wear of nylon
Clinical manifestation
1. Thrush:
2. Creamy whit plaque on mucus membrane and
lateral border of the tongue
3. Lesion cover the oral cavity &cause mild
discomfort
Candidal diaper :
1. Acute onset of erythema begin in perineal
area
•
erythematous skin occur in apposed surface
as axillae
Treatment& Nursing
management
Candidal diaper:
• change diaper as soon as soiled
• Avoid over washing the skin
• Apply ointment as Zink oxide nystatine
cream & or 1%hydrocortisone
• keep the area dry and exposed to air
Thrush:
1. Oral nystatin 4-6 hrs interval &continue 48hrs
after resolution of the symptom
2. nystatin cream to nipple with Candida
2- tinea
• Definition:
It is a superficial fungus infection of
the skin. It is highly contagious
• Classification: according to part
affected
1. worm of Ring scalp (Tinea Capital)
2. worm of Ring of skin (Tinea corporis)
3. worm of Ring of feet (Tinea pedis)
Tinea Capital

It is the most common dermal infection children &
occur frequently at school age
It transmitted more often from contact with fomites
than direct contact
Clinical manifestation:
Lesion inform of circular patch about 2inch in
diameter with or without alopecia
Alopecia are demarcated with or without erythema
Skin become scaly & black dotes result from broken
hair
crusting, pustules ,and lymphadenopathy
Kerions ,are moist, boggy, scalp nodule
Tinea capital
Treatment& Nursing
management
• Oral administration of grisefofulvin +the
use of shampoos containing 1%selenium
sulfide help to limit the spread of spores.
• Terbinafine & fluconazole help in short
treatment
• Head should covered with skull cap that
must be washed daily
• All object that have come into contact
with the infected child must clean
thoroughly.
Infestation
A-scabies :
-caused by scabies mite
-it transmitted from person to person
- Incubation period 2-6 week during this
period the infection can transmitted
-Parasite burrows itself in the skin for
depositing egg
Clinical Manifestation
• Parts that involved are moist, wet skin
i.e, axilla, between fingers, toes, around
umbilicus, genitalia.
• Lesions appear as dark blue lines
indicating the path used by the itch mite
to burrow itself& color due to fecal
deposition
• Sever itching
• in second infection ,papules, vesicles,
pustules occur
Treatment& Nursing
management
• Permethrin or preparation contain
DDT as benzyle
• The child should bathe in tepid water
the skin dry, the scabicide applied
• Attention should given to folded area
• Then child put in clean clothes
• All child clothes and bedding should
be washed in hot water and dried in
a hot dryer
• Cut the nail &prevent the scratch.
pediculosis
•
•

It is infestation of child with pediculi
There are three types:
Pediculosis Capital
Pediculosis pubic : pubic in old, in
eyelashes in young children
3. Pediculosis corporis (body)
Each type caused by different louse
Pediculosis
capitis
• Incidence and Etiology :
1. It is a head lice, it is common in
children 3-10 years.
2. The risk increase in girls ,at school
age.
3. It transmitted through head to head
contact.
4. The classroom considered as a
primary source of infestation.
Path physiology
• Head lice can crawl quickly on dry
hair. The female lives on scalp and lay
4-10 egg, it attached to end of hair
(nit), water insoluble substance holds
the nits to hair
Treatment& Nursing
management
• Use of pediculocides to remove the nit
• A solution of 1% permethrin for killing
pediculosis
• Combing hair with fine toothcomb dipped
in hot
• Antibiotics if pustules appear in neck
• Clothes and head cover should cleaned
boiled and dried
Clinical Manifestation
• Persistent itching , pruritus in the
occipital area.
• Persistent scratching result in excoriation
& secondary infection.
• Enlargement of posterior cervical gland
Intestinal parasite
