There is substantial to excellent agreement on the TJC, PASI, NN, and mNAPSI among rheumatologists and dermatologists.

Psoriasis is a common chronic inflammatory skin disease that is increasingly being recognized as a disease that not only affects the skin but also has multi-systemic implications. The pathophysiological link between psoriasis and obesity is becoming increasingly elucidated by recent studies. The cross-talk between adipocytes and the immune system via various mediators such as adipokines could explain how obesity contributes to psoriasis. The effects of obesity on adipocytes include upregulation of pro-inflammatory adipokines such as leptin and resistin, downregulation of anti-inflammatory adipokine, and also the stimulation of pro-inflammatory cytokine production by macrophages. This article provides an update on the role of adipose tissues in psoriasis.

The Q-switched 1064-nm neodymium-doped yttrium aluminum garnet (QS 1064-nm Nd:YAG) laser is increasingly used for nonablative skin rejuvenation or "laser toning" for melasma. Multiple and frequent low-fluence, large-spot-size treatments are used to achieve laser toning, and these treatments are associated with the development of macular hypopigmentation as a complication. We present a case series of three patients who developed guttate hypomelanotic macules on the face after receiving laser toning treatment with QS 1064-nm Nd:YAG.

Narrowband ultraviolet B (NBUVB) phototherapy is a well-established treatment modality for psoriasis. We performed a retrospective analysis of children of East Asian descent with psoriasis treated with NBUVB phototherapy at the National Skin Centre, Singapore, over a 5-year period between 2004 and 2008 and found that NBUVB phototherapy is safe and effective for the treatment of psoriasis in children of East Asian descent.
