Acne in five minutes

Précis of the video

This is a quick introduction to the key features of acne. There are three main contributory factors: sebum production, infection, and ‘blockage’ or disordered keratinisation of the follicular epithelium. These three pathogenic factors, lead onto the three main therapeutic strategies.

Video 1 supporting material

Acne and acne inversa are covered in edderm101: core diseases, chapter 2. The biology of the sebaceous glands is described in edderm101: core concepts, chapter 2.

Eczema in five minutes

Précis of the video

This is a quick introduction to the key features of eczema. Eczema can be considered a simulacrum of the whole of Dermatology.  The diagnosis is clinical, the role of investigations limited, the range of physical signs enormous, the differential large, our understanding incomplete, and treatment largely empirical. Finally, management is dependant on rich clinical experience and insight into what patients want, what they need, and how they can be helped. I find it difficult to think of any other disease where misinformation figures so largely in producing poor care.

Eczema is covered in edderm101: core diseases, chapter 4.

Psoriasis in five minutes

Précis of the video

This is a quick introduction to the key features of psoriasis.

 Video 3 supporting materials

Psoriasis is covered in edderm101: core diseases, chapter 1. The ‘white scale’ discussion is the subject of the next video (Video 4)

edderm101: video 4:

Why does psoriasis sometimes look white? (<3 mins)

Précis of the video

In psoriasis we know there is inflammation, and an increase in epidermal turnover. Inflammation is accompanied by an increase in blood flow, so why does psoriasis sometimes look white, and why dose it change colour when emollients are applied? Some simple optics, explains all.

 Video 4 supporting material

None.

Antihistamines and eczema. Confused? (4 mins)

Précis of the video

Antihistamines are widely used in the management of atopic dermatitis. Yet, we know that histamine is not important in the pathogenesis of atopic dermatitis. What is going on? Well first, prescribing non-sedative antihistamines is generally a mistake: histamine is not a mediator of itch in atopic dermatitis. But sedative antihistamines are useful — not as antihistamines, but as sedatives.

Video 5 supporting material

The physiology of itch is discussed in edderm101: core concepts, chapter 3, and atopic eczema is covered in edderm101: core diseases, chapter 4.

Problems with gloves? (5 mins)

Precise of the video

Glove use by health care staff has risen dramatically over the last quarter century chiefly because of concerns about spread of infection diseases. Glove use also has a downside in that some people are susceptible to a variety of dermatological problems caused by gloves. It is important — largely based on the history — to be able to parse the patient’s story into one of the main clinical syndromes. So you have to think, is this a type 1 hypersensitivity disorder, or  a type 4 response, or an irritant reaction. Are you thinking contact urticaria or eczema? And how are you going to confirm your clinical suspicions, and how will you advise the patient?

Video 6 supporting material:

You can read more on this in the chapters on dermatitis (chapter 4) and urticaria (chapter3) in edderm101: core diseases. Chapter 4 in edderm101: core concepts provides a short overview of skin immunology (and see Video 9 in the Core Concepts series).

edderm101: video 7:

Drug rash: what do you mean? (< 5 mins)

Précis of the video

The term drug rash is useful, but it is also wonderfully vague. In many clinical situations what we want to know is ‘what type of drug rash’ are we looking at. The key here is not just to concentrate on the causative agent, but to think hard about the morphological pattern. If somebody develops a type I urticarial reaction to a penicillin, we have to worry about anaphylaxis. Similarly if somebody develops TEN, we are worried about the high case-fatality rate. On the other hand, a lichenoid rash from a drug, or a fixed drug eruption, whilst important, allows us to operate under a very different time scale.

Drug rashes are covered in edderm101: core diseases, chapter 9.

Acne lecture (32 mins)

Précis of the video

This is very much a talkover of a standard PowerPoint style lecture.  It covers closely the material in Chapter 1 edderm101, but there is more information in the text. I do not talk about acne inversa (which is covered in edderm101).
