Keratinocyte carcinoma as a chronic disease in Australia and Spain: The importance of avoidance of perceived visible scars.

Background/objectives: Keratinocyte cancer impacts health-related quality of life (HRQL). Disease progression and treatment can lead to adverse physical and psychosocial consequences. The skin cancer index (SCI) is a validated tool with higher scores reflecting greater HRQL.

Multiple benign adnexal tumours: Anything but benign.

Muir Torre syndrome is an autosomal dominant disorder characterised by germline mutations in mismatch repair genes involved in DNA repair, leading to microsatellite instability and a propensity to tumour formation. We report a case of a 67-year-old gentleman who underwent biopsy of a smooth nodular lesion on the nasal tip, histopathologically consistent with sebaceous adenoma. Immunohistochemistry suggested a loss of MSH6.

Factors affecting choice of repair in Mohs micrographic surgery for non-melanoma skin cancer of the head.

Background/objectives: In Mohs micrographic surgery (MMS) the dermatologist serves as surgeon, pathologist and reconstructive surgeon. Analysis of the factors that play a part in determining defect size and closure type may result in better patient outcomes. The objective was to identify factors contributing to the defect size and closure method employed in MMS.

The microbiome and atopic eczema: More than skin deep.

Discoveries in the defective molecular composition of the epidermal barrier, such as the epidermal protein filaggrin, in those with atopic eczema (or atopic dermatitis [AD]) have proved crucial in understanding this disease, but its aetiology remains to be fully elucidated. The epidermal barrier is just one interface between the microbial world and our immune system. Recent advances in molecular technology have demonstrated for the first time the true scale of the normal human microbiome and changes seen in disease states.

Overcoming status quo bias in the human brain.

Humans often accept the status quo when faced with conflicting choice alternatives. However, it is unknown how neural pathways connecting cognition with action modulate this status quo acceptance. Here we developed a visual detection task in which subjects tended to favor the default when making difficult, but not easy, decisions.
