Bullous Impetigo is a cutaneous condition that characteristically occurs in the newborn, and is caused by a bacterial infection, presenting with bullae.
It can be caused by Exfoliative toxin A. The phyogenic superficial infection can be divided into two other subdivisions; Impetigo, and non-bullous impetigo. Bullous impetigo is caused by Staphylococcus aureus, which produces exfoliative toxins, whereas impetigo is caused by either Staphylococcus aureus, or Streptococcus.[3] Bullous Impetigo can cause deaths in fewer than 3% of infected children, but up to a 60% death rate in adults. 30% of all Impetigo cases are related to Bullous impetigoBullous impetigo can appear around the diaper region, axilla, or neck. The bacteria causes for a toxin to be produced with reduced cell-to-cell stickiness (adhesion), causing for the top layer of skin (epidermis), and lower layer of skin (dermis) top separate.[6] Vesicles rapidly enlarge and form the bullae which is a blister more than 5mm across. Bullae is also known as Staphylococcal scalded skin syndrome. Other associated symptoms are itching, swelling of nearby glands, fever and diarrhea. It should also be noted that pain is very rare.
Diagnosis
Observing the skins physical appearance, or swabbing a culture of the lesion for S. aureus. Nasal swabs from the patient’s immediate family members are necessary to identify them as being asymptomatic nasal carriers of S. aureus.
Long term effects: Once the scabs on the bullous have fallen off scarring is minimal. Possible long term effects are kidney disease
Possible misdiagnoses
HPV
insect bites
burns
