Derm- hair, feet, nails, sweating Flashcards
General measures to manage “pompholyx eczema”
Vesicular hand/foot dermatitis presents as recurrent crops of deep-seated blisters on the palms and soles. They cause intense itch or a burning sensation. The blisters peel off and the skin then appears red, dry and has painful fissures (cracks).
Wet dressings to dry up blisters, using dilute potassium permanganate, aluminium acetate or acetic acid
Cold packs
Soothing emollient lotions and creams
Potent antiperspirants applied to palms and soles at night
Protective gloves should be worn for wet or dirty work
Well-fitting footwear, with 2 pairs of socks to absorb sweat and reduce friction
Treatment for cracked heals
(6)
- Advise patients to avoid soaps and irritants.
- Advise patients to use a soap-free wash, and to frequently apply a greasy emollient.
- Wearing closed footwear may help.
- A cream containing urea 10 to 25%, or salicylic acid 3 to 6%, can be used for treatment.
- For exfoliation, pumice stone can be used in the shower.
- Seek podiatrist advice for symptom management, if needed
What is this?
How do you treat it?
4 general measures
1 x medication option with full dosing
Pitted keratolysis
General measures
Foot hygiene: clean shoes, socks
Keeping foot dry
Wash regularly with an antiseptic wash
Antiperspirant on foot/feet
If general measures fail then
clindamycin 1% lotion topically, twice daily for 10 days.
This condition relapses and remits spontaneously and occurs more so in children.
What is it
How do you manage the following situations?
1. Limited hair loss of recent onset
2. Extensive hair loss OR
Alopecia Areata
Autoimmune condition
- Can use a potent topical steroid in lotion form
betamethasone dipropionate 0.05% lotion topically, once or twice daily for 3 to 4 months - Refer to dermatology
and / or discuss acceptance and psychology counselling and camouflage options.
What is acute telogen effluvium ?
Excessive shedding of the hair after a stressful life event. (psychological, birth, surgery, crash diets/weight loss, new drugs, severe illness)
Acute version should resolve in 6 months
What is Chronic telogen effuluvium?
What are the symptoms?
Excessive hair shedding over 9 months
Can have burning sensation and itching
Cause is idiopathic (spontaneous)
Can refer to derm if unsure
Try to identify trigger and remove
Drugs not usually needed
Some evidence of iron supplementation if iron deficent
By the age of 70 years, approximately 80% of Caucasian males and 60% of Caucasian females are affected by this.
What is it?
Androgenetic Alopecia
Advice to give patients about the therapy/management for Androgenetic Alopecia?
- Set realistic expectations
- Primary aim is to slow down hair loss
- Secondary aim is to stimulate hair growth
- Using photography is the best way to assess effectiveness
- Effects are not immediate. Topical treatments take 3-6 months and oral take 6-12 monhs
Treatment available for treating Androgenetic Alopecia?
minoxidil 5% foam 1 g (approximately half a capful) topically to the scalp to cover sparse areas, once or twice daily for at least 6 to 12 months
finasteride 1.25 mg (quarter of a 5 mg tablet) orally, once daily
for NON PREGNANT females
spironolactone 50 to 100 mg orally, once daily, increase to 200 mg daily if no benefit is apparent after 6 to 12 months.
Other non medical treatments for androgenetic alopecia?
Evidence for laser treatments, commercially available hair tonics and nutritional supplements to treat hair loss is lacking.
Platelet-rich plasma injections are increasingly used to stimulate hair regrowth in selected patients; however, they are unregulated in Australia
what is this?
And what is the cause?
Trichotillomania is an impulse control disorder characterised by compulsive hair pulling or plucking
WIth children, trichotillomania is usually a benign habit that resolves with age, but sometimes it is a response to stress at home or school. Parental help to curb this habit is often adequate, but referral to a child psychologist or psychiatrist may be indicated.
In adults it tends to be associated with a psychological disorder like anxiety / OCD
What causes Scaring alopecia?
chronic cutaneous [discoid] lupus erythematosus, lichen planopilaris, frontal fibrosing alopecia, folliculitis decalvans
If suspected, refer to dermatologist
How do you treat this?
terbinafine 250 mg (child less than 20 kg: 62.5 mg; child 20 to 40 kg: 125 mg) orally, once daily until clinical clearance
After starting treatment for onychomyocosis when do you review and refer?
How can you assess continued improvement?
New nails take about 9-12 months to grow.
After 3 months the nail will still look abnormal
if at 3 months there is some proximal improvement i.e healthy nail, then continue treatment
However if there is no improvement then refer to derm.
To assess if treatment is still working, make a scratch with a scalpel blade at the proximal end of the dystrophy after 3 months of treatment. The patient can follow the scratch as the nail grows out. If the dystrophy stays distal to the scratch, continue treatment until clinical clearance. If the dystrophy moves proximal to the scratch, refer to a specialist.
Management of an ingrown nail
1st line?
Is actually conservative
- Avoid environmental factors i.e do not cut the nail to acheive a curve, wearing pointed toe or high heeled shoes, onychomyocosis, repeated trauma and oral retinoids
- Cut the distal edge in a straight line
- gently lift the nail edge out of the lateral nail fold. May need to file the distal nail down to make it thin. Pack moistened (in 70% alcohol) cotton wool under the nail to keep it elevated. Repack dailly.
- Topical antiseptic if appearing infected povidone-iodine 10% ointment topically, under occlusion.
