Impetigo Flashcards
What is impetigo?
A contagious, superficial bacterial skin infection, usually caused by staphylococcus aureus
Impetigo is characterized by its contagious nature and superficial infection of the skin.
What is a characteristic appearance of a staph skin infection?
A ‘golden crust’
This appearance is a hallmark of impetigo, particularly in its non-bullous form.
What are the two types of impetigo?
- Non-bullous impetigo
- Bullous impetigo
These two types differ in their presentation and management.
Where is non-bullous impetigo typically found?
Around the nose or mouth
Non-bullous impetigo usually manifests in these facial areas.
What is the appearance of lesions in non-bullous impetigo?
Exudate from lesions → ‘golden crust’
This exudate is a key feature that helps in identifying the condition.
Does non-bullous impetigo usually have systemic symptoms?
No, the person is generally well
This type of impetigo typically does not cause systemic illness.
What is a common management option for non-bullous impetigo?
- Topical fusidic acid
- Oral flucloxacillin (if more widespread or severe)
The choice of treatment depends on the severity and spread of the infection.
What advice is given to prevent the spread of non-bullous impetigo?
- Do not touch or scratch lesions
- Hand hygiene
- Not sharing towels
- Stay off school until all lesions have healed or been treated with antibiotics for at least 48 hours
These measures are essential to limit transmission of the infection.
What are the characteristics of bullous impetigo lesions?
1-2cm fluid-filled vesicles that burst and form a ‘golden crust’
These lesions can be painful and itchy, distinguishing them from non-bullous impetigo.
In which population is bullous impetigo more common?
Neonates and children under 2 years
This demographic is particularly susceptible to bullous impetigo.
Can bullous impetigo present with systemic symptoms?
Yes, it may have systemic symptoms such as fever and generally unwell feeling
This distinguishes bullous impetigo from its non-bullous counterpart.
What syndrome can occur when bullous impetigo is widespread?
Staphylococcus scaled skin syndrome
This severe condition arises from extensive bullous impetigo infections.
What is the management for bullous impetigo?
Oral flucloxacillin
Treatment typically requires systemic antibiotics due to the severity of the infection.
Is the advice for preventing the spread of bullous impetigo different from non-bullous impetigo?
No, the same advice applies
Both types require similar preventive measures to avoid spreading the infection.
