UW Peds Derm Flashcards
Tx tinea corporis
Terbinafine
Neonate with sensorineural hearing loss, PDA, cataracts, and/or glaucoma
Congenital rubella
Cephalocaudal spread (face to body) of maculopapular exanthum
Rubella
Patchy erythema on the soft palate in rubella is called
Forschheimer spots
What type of virus is rubella?
RNA togavrius
fever and sandpaper texture (tiny papular) rash that spreads cephalocaudally and is most pronounced in skin folds
scarlet fever
benign vascular tumors of childhood that appear during the first weeks of life, initially grow rapidly, and typically regress by 5-8 years; composed of capillaries separated by connective tissue
strawberry hemangiomas
dilated cuteness arterioles that present as central papule with radiating blanching capillaries
spider angiomas (a/w pregnancy, liver disease, OCPs)
soft blue compressible masses up to a few centimeters in size light microscopy reveals large dilated vascular spaces
cavernous hemangioomas
benign tumors that consist of dilated lymphatic spaces lined by endothelium; they most commonly occur on the neck. tumors are lobulated, compressible, and usually transilluminate
Cystic hygroma
numerous umbilicated vesicles over healing atopic dermatitis
eczema herpeticum
benign neonatal rash characterized by blanching erythematous papillose and/or pustules that resolves spontaneously within 2 weeks after birth
Erythema toxicum
pathophys of SSSS
exfoliative toxin producing strains of S aureus target desmoglein 1, which is responsible for keratinocyte adhesion in the superficial epidermis, usually with a prodrome of fever, iribility, and skin tenderness
what do you call it when gentle lateral pressure on the skin surface adjacent to a blister causes slipping and detachment of a superficial layer of skin?
Nikolsky sign (SSSS)
populations affected by SSSS.
Kids under 10 and adults with kidney disease or immunocompromise
what bug causes impetigo
S auresu or group A beta hemolytic strep
12-48 hrs after prodrome, fine pink blanching papillose appear on the neck and upper trans and quickly generalize with flexural accentuation, said to have a rough, sandpaper like texture
scarlet fever
bacterial infection of the dermis that typically manifests as a well-demarcated, red, indurated, warm, tender plague, sometimes with overlying vesicles and bull, and lymphangitis streaking away from the plaque
Erysipelas
bug of eryispelas
Group A strep
allergic cotnact dermatitis is due to cell-mediated hypersensitivity, also called
type IV or delayed hypersensitivity
IgE mediated hypersensitivity, such as atopy, urticaria, and anaphylaxis, occurs when allergen binds and cross links two IgE molecules attached to the mast cell. Also called:
Type I or immediate hypersensitivity
antibody mediated HS = cytotoxic and includes specifi reactions of IgG or IgM to cell bound antigens. The antibodies then activate complement. Examples include immune hemolytic anemia and Rh hemolytic disease in the newborn
Type II HS
Immune complex mediated HS is also called? Antibodies of IgG or IgM form complexes with antigens and nonspecifically activate the complement cascade and other inflammatory processes. Examples include serum sickness and Arthus reaction
Type III HS
Platelet count in HSP
NORMAL (abdominal pain, arthralgia, and renal disease)
life threatening condition seen with bacterial infections such as N meningitidis and s pneumo that presents with blue or black hemorrhagic purpuric lesions
Purpura fulminans
papular scaly rash usually in eyebrows, nasolabial folds, and scalp
seborrheic dermatitis
scaly erythematous lesions on face, chest, and extensor surfaces on infant (flexural in kids)
eczema
