Patient-Oriented Eczema Measure score: A Useful Tool for Web-Based Surveys in Patients with Atopic Dermatitis.

The Patient-Oriented Eczema Measure (POEM, 0-28 points) is a self-assessed, repeatable measurement tool for measuring atopic dermatitis (AD) severity. How-ever, whether POEM score is influenced by allergic comorbidities and whether POEM's severity banding is applicable in web-based surveys for AD remain unclear. A web-based questionnaire survey was conducted in 329 patients with AD. POEM, self-reported severity of AD, and comorbidity of allergic diseases including asthma, pollen rhinitis, allergic conjunctivitis, and food allergy were assessed. POEM scores were not affected by a history of comorbid allergic diseases. The severity banding for POEM scores on the web-based survey was as follows: clear/almost clear = 0, mild = 1-8, moderate = 9-21, and severe/very severe = 22-28, which was comparable to previous banding. These results suggest that POEM is useful for determining AD severity, even in web-based surveys. Patients with POEM scores above 9 points may be grouped into moderate, severe, and very severe AD.

Reduction of serum TARC levels in atopic dermatitis by topical anti-inflammatory treatments.

BACKGROUND: Serum thymus and activation-regulated chemokine (TARC) levels are associated with the disease activity of patients with atopic dermatitis (AD) and sensitively reflect short-term changes in skin conditions. The main treatment for AD is topical agent application. OBJECTIVE: This study investigated the relationship between serum TARC levels and the dosage of topical agents, including corticosteroids and/or tacrolimus, in patients with AD. METHODS: The serum TARC levels of 56 AD patients and the amounts of topical agents prescribed to them were investigated retrospectively. The weekly reduction in serum TARC levels and weekly dosage of topical agents among AD patients were compared and their associations were evaluated. RESULTS: The dosage of topical agents was closely related to serum TARC levels. One gram of strong rank steroid or the equivalent amount of steroid/tacrolimus is required to reduce serum TARC levels by 9.94 pg/mL weekly in moderate to severe AD patients. Higher initial TARC levels require more topical agent, which results in a more rapid decrease in TARC levels. The serum TARC levels and eosinophil numbers in peripheral blood are significantly correlated. CONCLUSION: Serum TARC level improvement and topical agent dosage are strongly correlated. TARC and eosinophil numbers are significantly correlated, but the wider range of TARC levels seems to be clinically more useful for monitoring AD severity. The serum TARC level is a very sensitive biomarker for monitoring the severity and treatment response in AD.

Overexpression of cathepsin D in malignant melanoma.

Cathepsin D is an aspartic lysosomal endopeptidase present in most mammalian cells. Overexpression of cathepsin D is associated with the progression of several human cancers including melanoma. We examined the expression levels of cathepsin D in 20 primary malignant melanomas, 20 metastatic malignant melanomas, 20 benign nevus pigmentosus and 10 normal skin samples in Japanese. In normal skin, granular or dotted pattern of positive staining was observed along the granular layer of epidermis and hair follicle with apparent moderate to strong staining in sebaceous and eccrine glands. The percent positivity and staining intensity of cathepsin D in primary and metastatic malignant melanomas were significantly higher than that of nevus pigmentosus. Moreover, the expression levels of cathepsin D in metastatic malignant melanomas were significantly higher than those of primary malignant melanomas. Data from our and previous reports strongly supports a notion that the upregulation of cathepsin D may be critically involved in the malignant transformation and progression of melanocytic tumors.

Radiation-induced skin ulcer and rib fractures following percutaneous coronary intervention (PCI): A case of right back skin ulcer and adjacent rib fractures after single PCI.

We experienced a 75-year-old male patient with a refractory and severely painful skin ulcer on the right back. He had suffered from ischemic heart disease and undergone percutaneous coronary intervention 5 months prior to the consultation with us. The characteristic clinical appearance, location of the lesion and his past medical history led us to the diagnosis of radiation-induced skin ulcer. Magnetic resonance imaging, computed tomography as well as bone scintigraphy showed fractures of the right back rib adjacent to the ulcer, which was thought to be attributable to bone damage due to X-ray radiation and/or persistent secondary inflammation of the chronic ulcer. In the published work, there are no other reports of bone fractures associated with radiation dermatitis after coronary interventional radiology.
