Obese and overweight individuals may have a wide spectrum of cutaneous features and can have more severe manifestations of multiple dermatological conditions. There have been multiple expert opinions on the role of weight loss, in the improvement of skin conditions. There have been few studies over the past decade evaluating the effects of exercise and other modes of weight reduction on various dermatoses such as psoriasis, acne vulgaris, hidradenitis suppurativa and acanthosis nigricans. In this review, we have attempted to provide a summary of the beneficial effects of weight loss on various dermatological conditions. [ABSTRACT FROM AUTHOR]

Tofacitinib has revolutionized the treatment of numerous dermatological conditions in different age groups. However, evidence for its effectiveness, safety and tolerability in the paediatric population is limited. We performed a literature search, which showed that oral tofacitinib is a reliable option in refractory juvenile dermatomyositis, severe alopecia areata, atopic dermatitis and psoriasis. Topical tofacitinib is an effective option in vitiligo and halo naevus. The risk–benefit ratio should be assessed prior to consideration of this molecule. In this narrative review, we have attempted to present a summary of the evidence of using tofacitinib (oral and topical) in paediatric dermatoses. [ABSTRACT FROM AUTHOR]
