Chronic venous disease, platelet and haemostatic abnormalities contribute to the pathogenesis of pigmented purpuric dermatoses.

Background: To investigate the aetiology of pigmented purpuric dermatoses (PPD).

Methods: 63 patients with a provisional diagnosis of PPD were assessed. Skin biopsies were performed to confirm the clinical diagnosis.

Scar outcomes in dermatological surgery.

Background/objectives: Significant functional impairment and psychological burden may result from poor scar quality and its impact on patient's quality of life has been well-established. It is important to identify measures to reduce the risk of surgical complications.

Method: 212 patients undergoing dermatological surgery were recruited from March 2011 to February 2014.

Oral nicotinamide and actinic keratosis: a supplement success story.

Nicotinamide has shown potential as a safe and effective intervention for the prevention of malignant and premalignant skin lesions. Recent studies have shown that nicotinamide, in both oral and topical forms, is able to prevent ultraviolet-induced immunosuppression in humans [1,2,3] and mice [4,5]. Immunosuppression is a known factor for the progression of premalignant lesions, such as actinic keratosis [6].
