In order to investigate the influence of low relative humidity, we measured saccharin clearance time (SCT), frequency of blinking, heart rate (HR), blood pressure, hydration state of skin, transepidermal water loss (TEWL), recovery sebum level and skin temperature as physiological responses. We asked subjects to judge thermal, dryness and comfort sensations(More)
IMPORTANCE Despite the growing literature on comorbidity risks in psoriasis, there remains a critical knowledge gap on the degree to which objectively measured psoriasis severity may affect the prevalence of major medical comorbidity. OBJECTIVE To examine the prevalence of major medical comorbidity in patients with mild, moderate, or severe psoriasis,(More)
Oxidative damage to DNA has been implicated in carcinogenesis during chronic inflammation. Epidemiological and biochemical studies suggest that one potential mechanism involves myeloperoxidase, a hemeprotein secreted by human phagocytes. In this study, we demonstrate that human neutrophils use myeloperoxidase to oxidize uracil to 5-chlorouracil in vitro.(More)
In order to compare the physiological and the subjective responses to low relative humidity of elderly and young men, we measured saccharin clearance time (SCT), frequency of blinking, hydration state of the skin, transepidermal water loss (TEWL), sebum level recovery and skin temperatures as physiological responses. We asked subjects to evaluate thermal,(More)
BACKGROUND There is little evidence to guide the establishment of treatment goals for moderate to severe psoriasis in the clinical setting. OBJECTIVE We sought to compare Dermatology Life Quality Index scores and prescription topical medication use between patients with clear versus almost clear skin. METHODS This was a multicenter cross-sectional study(More)
Psoriasis is a common chronic inflammatory disorder, primarily of the skin. Despite an aging population, knowledge of the epidemiology of psoriasis and its treatments among the elderly is limited. We examined the prevalence of psoriasis and its treatments, with a focus on biologics and identification of factors associated with biologic use, using a(More)
the buttocks, axillae, and groins and evolved in crops. Besides these nodules, physical examination revealed bridged scars, but no interconnecting tracts. Histologic examination of a skin biopsy and cultures ruled out Crohn disease and an opportunistic infection, respectively. The diagnosis was HS grade II according to the Hurley classification. A 6-month(More)
BACKGROUND Psoriasis, especially when severe, is a risk factor for cardiometabolic disease beyond traditional risk factors. The mechanism of atherogenesis in psoriasis remains unknown. Cell membrane vesicles (ie, microparticles), released upon cell activation or apoptosis, have recently been associated with cardiometabolic disease and may play a pathogenic(More)
Somatic mutations induced by oxidative damage of DNA might play important roles in atherogenesis. However, the underlying mechanisms remain poorly understood. Myeloperoxidase, a heme protein expressed by select populations of artery wall macrophages, initiates one potentially mutagenic pathway by generating hypochlorous acid. This potent chlorinating agent(More)
OBJECTIVE To determine the risk of fracture and osteoporosis among patients with psoriatic arthritis (PsA) and psoriasis, compared with the general population and patients with rheumatoid arthritis (RA). METHODS A population-based cohort study was performed in The Health Improvement Network in the UK using data from 1994 to 2014. Patients aged 18-89 years(More)
