Meta AnalysisAssociation of the tumour necrosis factor-α polymorphisms rs361525 and rs1800629 with susceptibility to psoriasis: a meta-analysis.
Evidence has suggested that tumour necrosis factor (TNF)-α may be involved in the aetiology of psoriasis, but the underlying association of the TNF-α polymorphisms -238G/A (rs361525) and -308G/A (rs1800629) with the risk of psoriasis is still unconfirmed. ⋯ This meta-analysis suggests that the TNF-α -238 and -308 promoter polymorphisms may play different roles in conferring susceptibility to psoriasis. Functional and well-designed studies should be conducted to confirm these results.

Case ReportsMycobacterium chelonae infection: a complication of tattooing.
We describe an outbreak of Mycobacterium chelonae infection in four young immunocompetent patients who were tattooed by the same artist. All had been previously tattooed without complication, but following the latest tattooing session, they all developed a very similar papular eruption confined to skin that had been newly coloured light grey. ⋯ M. chelonae was also cultured from the contents and nozzle of an opened bottle of light-grey ink from the tattoo parlour frequented by the patients. Dermatologists should consider mycobacterial infection in patients who develop inflammatory changes within a new tattoo.
