Haemosiderin staining

"Haemosiderin staining" describes orange/red/brown skin hyperpigmentation caused by haemosiderin (an iron-containing pigment found in blood) leaking into the skin.

Causes:

Chronic venous insufficiency (in lower legs)

Skin inflammation

Trauma e.g. wound, fracture, surgery

Pigmented purpuric dermatoses

Haemochromatosis

Haemosiderin staining may be exacerbated by anticoagulant use as this increases extravasation (leakage) of red blood cells into the skin.

See an example here.

Oedema - pitting vs non-pitting

Oedema is swelling due to excess fluids in tissues.

In pitting oedema, pressing on the affected area leaves an indentation (that persists after removing the pressure). In non-pitting oedema, the area feels firm to touch and does not form indentations.

Pitting oedema:

The excess fluid is mainly composed of water

Commonly caused by heart failure, venous insufficiency, or nephrotic syndrome

Non-pitting oedema:

The excess fluid consists of water WITH protein and salts

Usually indicates a condition of the thyroid / lymphatic system

Different types:

Lymphoedema is due to a build-up of lymphatic fluid (e.g. due to a tumour blocking lymphatic flow / after removal of lymph nodes).

Myxoedema occurs in hypothyroidism and often affected the pretibial or periorbital area.

Angioedema is localised swelling of the skin and is usually due to allergic reactions. It typically affects the face, tongue, larynx, abdomen, arms, and legs. When the larynx is affected, it may affect breathing, which is an emergency!

Lipoedema is when fat accumulates in subcutaneous tissues - it usually affects the legs/buttocks and almost exclusively occurs in postpubertal females (not the same as cellulite!)

If patients present with oedema, it's always important to test if it's pitting or non-pitting as this helps to determine the cause and correct treatment!

Okay, I asked ChatGPT to make me a monthly planner for taking care of my face. I really want to try it out. It didn't seem like anything was crazy extreme. Here is the result:

Certainly! Here's a monthly planner for facial skincare tailored to someone with sensitive skin:

Week 1:

Day 1-3: Gentle Cleansing & Moisturizing

Cleanse your face with a mild, fragrance-free cleanser morning and night.

Apply a soothing, hydrating moisturizer after cleansing.

Day 4: Exfoliation

Exfoliate with a sensitive-skin-friendly exfoliant (1-2 times a month).

Week 2:

Day 8-14: Cleansing & Hydration

Continue with your gentle cleansing and moisturizing routine.

Week 3:

Day 15: Exfoliation

Exfoliate with a sensitive-skin-friendly exfoliant (1-2 times a month).

Day 16-21: Cleansing & Moisturizing

Stick to your gentle cleansing and moisturizing routine.

Week 4:

Day 22-28: Focus on Hydration

Prioritize hydration with a hydrating sheet mask or a hydrating serum.

Note: Adjust the schedule as needed based on your skin's response. Always perform a patch test for new products, and consult a dermatologist if you experience any adverse reactions or concerns about your sensitive skin.

Remember, consistency is key in skincare, and for sensitive skin types, using gentle, fragrance-free products is crucial to prevent irritation.
