(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 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

- rash on interdigital web spaces, flexor wrists, extensor elbows, axillae, umbulicus, genitalia
scabies - treatment
topical 5% permethrin or oral ivermectin
neonatal rashes - types
- erythema toxicum neonatorum
- neonatal HSV

- 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 ACYCLOVIR
neonatal varicella - clinical manifestation / treatment
fever, ranges from vesicular clusters on skin to fulminant, disseminated disease
ACYCLOVIR
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

1st line: emollients, nonmedicated shampoos
2nd line: topical antifungals or low potency glucocorticoids
tinea corporis - RF
- athletes with skin-skin contact
- humid environment
- 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
reassurance
anti-histamine if pruritus
infectious complications of atopic dermatitis - types (and pathogens)
- impetigo (S. aureus, S pyogenes)
- Eczema herpeticum (HSV1)
- Molluscum contagiosum (Poxvirus)
- Tinea corporis (Trichphyton rubrum)
infectious complications of atopic dermatitis - types and presentation
- impetigo –> painful, non-pruritic pustuls with honey crusted adherent coating
- Eczema herpeticum –> painful vesicular rash with punched out erosions + hemorrhagic crusting
- Molluscum contagiosum –> fresh-colored papules with central umbilication
- Tinea corporis –> pruritic circular patch with central clearing + raised, scaly border
