Sunburn - clinical manifestation

symptoms begin hours after exposure, resolbe by day 3-7
mild-moderate: erythema, tenderness
severe: as above + blistering and systemic symptoms (eg. fever, vomiting, headache)


sunburn - treatment

mild - moderate: topical cool compressess, calamine lotion, alone vera, oral NSAID
severe: hospital, IV fluids and analgesia, wound care


sun protection (if avoidance is impossible)

sunscreens with sun protection factor 15-30 or higher, applied 15-30 minutes before sun exposure to allow the formation of a protective film on the skin and reapplied at least every 2 hours
(because is washed off with swimming and sweating


no in infants younger than 6 months

their skin and high surface area to body weight ration increases exposure to sunscreen chemicals


dark vs light clothes on sunprotextion

althoug dark attract more, the protect more


mongolian spot

aka congenital dermal melanocytosis
- benign, flat, blue-grey patches that are usually present over the lower back and buttocks (but can be anywhere)
- african, asian, hispanic, native american
- fades spontaneously during first decade


mongolian spot vs abuse

in abuse, bruises are tender, fade quickly, more varied in color


scabies - organism, route of transmission

- sarcoptes scabie mite
- person to person contact


scabies - clinical features

- extremely pruritic burrows + small erythematous papuls
- rash on interdigital web spaces, flexor wrists, extensor elbows, axillae, umbulicus, genitalia


scabies - treatment

topical 5% permethrin or oral ivermectin


neonatal rashes - types

1. erythema toxicum neonatorum
2. neonatal HSV
3. neonatal varicella
4. staph scalded skin syndrome


erythema toxicorym neonatorum clinical presentation / treatment

asymptomatic, scattered erythematous macules, papules + pustules throughout the body
- no treatment necessary (resolves within 2 weeks after birth)


neonatal hsv - clinical manifestation / treatment

3 patterns
- vesicular clusters on skin, eyes + mucous membranes
- central nervous system infection
- fulminant disseminated multi-organ


neonatal varicella - clinical manifestation / treatment

fever, ranges from vesicular clusters on skin to fulminant, disseminated disease


staph scalded skin syndrome - clinical manifestation / treatment

fever, irritability + diffuse erythema followed by blistering + exfoliation, positive Nikolsky's sign
treatment: oxacillin, nafcillin or vancon


seberrheic dermatitis - clinical features

peaks in infancy + adulthood
- erythematous plaques +/or yellow, greasy scales
- located on scalp, face, (eg. eyebrows/eyelids, posterior ears, nasolabial folds), umbilicus, diaper area


seberrheic dermatitis - treatment

1st line: emollients, nonmedicated shampoos
2nd line: topical antifungals or low potency glucocorticoids


tinea corporis - RF

1. athletes with skin-skin contact
2. humid environment
3. contact with infected animals (eg. rodent)


tinea corporis - presentation

- scaly erythematous pruritic patch with centrifugal spread
- subsequent central clearing with raised annular borders


tinea corporis - treatment

1st line/localized: topical antifungals (eg. clotrimazole, terbinafine)
2nd line / extensive: oral antifungas (terbinafine, griseofulvin)


tinea capitis - treatment

- oral grizeofulvin
- terbinafine


pityriasis rosea - treatment

anti-histamine if pruritus


infectious complications of atopic dermatitis - types (and pathogens)

1. impetigo (S. aureus, S pyogenes)
2. Eczema herpeticum (HSV1)
3. Molluscum contagiosum (Poxvirus)
4. Tinea corporis (Trichphyton rubrum)


infectious complications of atopic dermatitis - types and presentation

1. impetigo --> painful, non-pruritic pustuls with honey crusted adherent coating
2. Eczema herpeticum --> painful vesicular rash with punched out erosions + hemorrhagic crusting
3. Molluscum contagiosum --> fresh-colored papules with central umbilication
4. Tinea corporis --> pruritic circular patch with central clearing + raised, scaly border


Perianal dermatoses - types (and epidemiology)

1. contact dermatitis (MC in infants)
2. Candida dermatitis (2nd MC in infants)
3. perianal Streptococcus


Perianal dermatoses - types + appearance

1. contact dermatitis --> spares creases / skinfolds
2. Candida dermatitis --> beefy-red rash involving skinfolds with satellite lesions
3. perianal Streptococcus --> bright, sharply demarcated erythema over perianal / perianal area


Perianal dermatoses - types + treatment

1. contact dermatitis --> topical barrier ointment or paste
2. Candida dermatitis --> topical anti-fungal therapy
3. perianal Streptococcus --> oral antibiotics


irritant diaper dermatitis?

presents with erythema and skin breakdown in the diaper area due to prolonged exposure to urine or stool in the diaper, particularly in the setting of diarrhea


deliberate scald injuries are characterised by

sharp lines of demarcation, uniform burn depth and spared flexor surfaces


congenital melanocytic nevus

presents within the 1st few months of life as isolated hyperpigmented patches with an increased density of hair follicles
