Hello and welcome to the Zero Definals podcast. My name is Tom, and in this episode, I'm going to be talking to you about Impetigo.

And you can find written notes on this topic at zero definals.com slash impetigo, or in the dermatology section of the Zero Definals Pediatrics book.

So let's get straight into it.

Impatigo is a superficial bacterial skin infection usually caused by the Staphylococcus

aureus bacteria.

A golden crust is characteristic of Staphylococcus skin infections.

It's also less commonly caused by the Streptococcus pyogenes bacteria.

Impetigo occurs when a bacteria enters via a break in the skin and causes infection of that skin.

This may be an otherwise healthy skin or may be related to eczema or dermatitis. Impatigo can be classified as non-bullous or

bullus. Let's start by talking about non-bullous impotigo. Non-bullous impotigo typically occurs around the mouth or the nose.

The exudate, or the discharge from the lesions dry, and form a golden crust.

They are unsightly, but they do not cause systemic symptoms or make the person systemically

unwell.

Topical fucidic acid can be used to treat localized non-bullous impotigo.

The draft's nice guidelines from August 2019 suggest using antiseptic cream, such as hydrogen

peroxide 1% cream, as first line rather than antibiotics for localized non-bulous imbitigo.

Oral antibiotics such as flu-cloxacillin are used to treat more widespread or severe imbitigo.

Flucoxacillin is the antibiotic of choice for stapaphlocococcal infections and is worth remembering for your exams.

It's important to advise about measures to avoid spreading the impotigo.

Patients should be given advice about not touching or scratching the lesions,

hand hygiene and avoiding sharing face towels and cutlery. They need to be kept off school
