Yeah, I think I'll start now if that's OK. Ok. OK. I'll start. Hi, everyone. Thanks for joining. Uh My name is Anisa. I'm an F one working in Birmingham. And today I'm gonna be starting off the Dermatology teaching series, Mind the bleep. So today we're gonna be going over an introduction to dermatology. Um So in terms of what we'll talk about today, we'll talk about the basic anatomy of the skin. We'll talk about terminology used in dermatology to describe cutaneous signs. Uh We'll go through a framework on how we can use that to describe the cutaneous signs. We'll talk about how we can systematically approach, examining um from a dermatology perspective. So, looking at the skin, the hair, the nails and how we can summarize that um altogether. And if there's any questions, feel free to put them in the chart and then I can answer them as we go along or at the end. OK. So this is very basic. Um But just as a recap. So when we're thinking about the skin, we're thinking about the three main layers. So we've got the uppermost layer, the epidermis and we've got the dermis and we've got the subcutaneous tissue um or the fat layer. So we'll talk a bit about each of those layers. So, starting off with the epidermis, the epidermis is a majority made up of keratinocytes. It also contains melanocytes. So they're responsible for creating the pigment in the skin. And then the epidermis can be divided into four or five different layers and I'll go into those layers in a second. Then we've got the dermis. So the dermis just below the epidermis, they're connected via the dermo epidermal junction. Um So the dermis is composed of a superficial and a deeper layer. So the superficial layer is the papillary layer. Um and the deeper layer is the reticular layer. So there's lots of things going on in the dermis. We've got mast cells, fibroblasts, blood vessels, uh et cetera, et cetera. There's lots of stuff in the dermis. And then we've got the subcutaneous tissue and this is essentially the store of adipose tissue. Um So I'm not going into too much detail of this for now, but this is just an overview of the, the main layers. And then in terms of the epidermis, so I mentioned that we can divide that into four or five different layers. So um we've got the different stratum layers. We've got the stratum corneum, stratum, lucidum, granulosum, spinosum and basal. So, if I just briefly talk about what each of those layers are composed of, and this is an acronym that I like to use to remember what the different layers are. So come, let's get sunburnt. So it's starting from corneum. So starting from the top corneum, come, let's get sunburnt. That's just a, a quick way to remember it. So talking about the different layers. Uh So at the stratum bizarre. So this is where the mitosis, the replication of the keratinocytes occurs. And then we've got the stratum spinosum. So this is also known as the prickly layer. So it's where the keratinocytes are joined by the tight intercellular junctions. So those are known as desmosomes. Um then we've got the stratum granulosum. So here we have things like lipids and waterproofing molecules. This is where they are secreted. And then we've got the stratum lucidum. So this is a thin, very thin uh trans transparent layer of keratinocytes. So the stratum nucum is actually only present in areas of thicker skin. So for example, the palms or the soles of the feet. So it's not present in all um all over the body. And its main role is to reduce friction between the layer above and below. So, between the stratum granulosum and stratum corneum, and it also helps to protect the skin from moisture loss again, which is why it's important on the palms and soles. Then lastly, we've got the stratum corneum. So this is the visible layer at the top and this is where the uh keratinocytes basically shed and become uh new cells which are called corneocytes. So those are the 54 or five main layers of the epidermis. OK. And then again, a very basic image, but this just uh illustrates uh the basic uh ultrastructure of the skin. So you can see the hair follicle that goes into the dermis. Uh We've got the sweat pore which again, at the dermis going up to the top of the epidermis, as I mentioned before in the dermis, we've got things like vessels. Um You can see sweat glands, nerves as well going downwards and we've got the adipose tissue at the bottom um in the subcutaneous. But OK, so that's just a very brief overview of the anatomy of the skin. So now we're gonna be talking about dermatology history taking. Um So I can't see the chart but if anyone wants to just put in uh maybe questions that you would ask when taking a dermatology specific history and then we can see what other things we would ask as well. I don't know if I'm able to see the child or not. Um I'll read out when we get some responses. Cool. Thank you. So we have, if the patient has any rashes or lesions. Mhm Nice. Cool. So that's thinking about like the presenting complaint. Is there anything maybe we'd wanna know about past medical history, social history. So we have a Socrates based history. So site of the lesion rash, onset, physical description, distribution. Any associated symptoms exacerbating and alleviating factors. Any changes in the medications? No. Yeah. Cool. Well done that. Those are all really good points. So, yeah, we definitely can use Socrates. Um, when thinking about a dermatology.
