1
Q

Topical calcineurin inhibitors are free of the adverse effects of topical corticosteroids I.e. atrophy, striae, potential hypothalamo-pituitary-adrenal axis suppression

A

True

2
Q

Cyclosporine (a calcineurin inhibitor) lacks topical activity because its large molecular weight results in poor epidermal penetration

A

True

3
Q

Tacrolimus and pimecrolimus have lower molecular weights (than the oral calcineurin inhibitor cyclosporine) and so can penetrate inflamed skin

A

True

4
Q

A

True

9
Q

Chronic atopic dermatitis lesions of the face and flexures are most justified for treatment with topical calcineurin inhibitors

A

True (topical calcineurin inhibitors have comparatively superior/similar potency to a TCS that would not have been used on the face/flexures due to risk of TCS adverse effects)

10

True

14
Q

16
Q

A

True

17
Q

Although there have been 2 cases of oral SCC in oral lichen planus patients after treatment with tacrolimus ointment, further studies will clarify if there is a causal relationship

A

True

18
Q

Topical tacrolimus 0.03% ointment is generally for paediatric patients and the 0.1% ointment is generally for adult patients

A

True

19
Q

True

20
Q

A

True

21
Q

Topical tacrolimus and pimecrolimus, either as monotherapy or combined with oral hydroxychloroquine is effective in cutaneous lupus erythematosus

A

True (topical tacrolimus and pimecrolimus was equal to clobetasol propionate 0.05% ointment in facial LE)

22
Q

Topical tacrolimus 0.1% ointment and pimecrolimus 1% cream is useful in seborrheic dermatitis

True

23
Q

A

True

A

True

25
Q

Topical tacrolimus may result in local application site irritation

A

True

26
Q

The localised application site irritation due to topical tacrolimus is transient and decreases in prevalence over time

A

True

27
Q

Both topical tacrolimus and pimecrolimus are absolutely contraindicated in individuals with hypersensitivity to the active drug or components of the ointment/cream

A

True

28
Q

Both topical tacrolimus and pimecrolimus are relatively contraindicated in children less than 2 years of age

A

True

29
Q

Both topical tacrolimus and pimecrolimus are absolutely contraindicated in individuals with an active skin infection at the site to be treated

A

True

30
Q

Exposure to topical tacrolimus or pimecrolimus is not associated with an increase in the overall cancer rate

A

True

31
Q

The use of topical tacrolimus may be associated with an increased risk of T-cell lymphoma

A

True (although this may be inconclusive as another study found no increased risk of lymphoma in patients treated with topical calcineurin inhibitors, and that patients with atopic dermatitis itself was associated with an increased lymphoma risk although this study did not find any cases of lymphoma in topical calcineurin inhibitors users)

32
Q

There is a theoretical risk that topical calcineurin inhibitors may cause lymphoma, although available data on lymphoma following topical calcineurin inhibitor use are inconsistent and insufficient to draw a conclusion about the causal role

A

True

33
Q

Available data have found no evidence indicating that skin cancer is associated with topical calcineurin inhibitor use

A

True

34
Q

Combining UVB and tacrolimus seems to have a limited direct photocarcinogenic potential on keratinocytes compared to UVB alone

A

True

35
Q

Systemic absorption of topical tacrolimus in atopic dermatitis is low and not clinically significant

A

True (although marked systemic absorption has been observed in Netherton’s syndrome)

36
Q

Patients with Netherton’s syndrome treated with topical tacrolimus are at risk for systemic absorption of topical tacrolimus

A

True (serum levels elevated, although no signs or symptoms of toxicity have been observed) - tacrolimus can be switched to pimecrolimus

Q

Topical tacrolimus may cause enhanced facial flushing after alcohol ingestion

A

True

38
