(Barré) #1

DERMATOLOGY
TREATMENT


■ Same as SJS with burn care center admission, airway observation for pos-
sible oral mucosal sloughing, aggressive fluid rehydration, antibiotics only
when infection is present
■ Steroids are not recommended.
■ Mortality rate is 30–40% due to infection, fluid loss, and electrolyte disturbances.


IMPETIGO

Divided into two clinical types:



  1. Impetigo contagiosa
    ■ Caused by Staphylococcus aureusand group A streptococci
    ■ Superficial vesicles and pustules covered with honey colored crusts
    (see Figure 17.3)

  2. Bullous impetigo
    ■ Caused by epidermolytic, toxin-producing S. aureus
    ■ Flaccid vesicles and bullae up to 3 cm in diameter


SYMPTOMS/EXAM


■ Superficial bacterial infection of the epidermis commonly around the
nose and mouth of children <6 years old
■ Predisposing factors include poor hygiene, warm weather, overcrowding,
and breaks in skin barrier from abrasions or insect bites.


TREATMENT


■ Systemic and topical antibiotics are equally successful, with systemic pre-
ferred for more extensive infections. Neither treatment prevents the rare
development of acute glomerulonephritis.
■ Topical mupirocin 2% ointment
■ Systemic treatment: Previously treated with cephalexin, oxacillin. Due to
prevalence of CA-MRSA, current recommendations are for TMP-SMZ or
clindamycin.
■ Meticulous hygiene can prevent the spread.
