An Adolescent Patient with Scabies Mimicking Gottron Papules

Atypical features of scabies occur in infants and children and patients with prolonged use of corticosteroids or immunosuppression. We report a non-immunosuppressed 15-year-old female case of scabies showing scaly reddish papules over the proximal interphalangeal joints mimicking Gottron papules in classic dermatomyositis. Periungal erythema was also seen. Four months’ topical corticosteroids from previous clinics had been used. Dermoscopic findings were consistent with typical pictures of scabies. Scraping of hand crusts demonstrated scabies mites and ova. Skin lesions of the patient were cured with oral ivermectin and topical 10% crotamiton. This case suggests that a lesion resembling Gottron papules may be added to the panel of unusual presentations of scabies

Genital Infection as a First Sign of Acute Myeloid Leukemia

Fournier's gangrene is a life-threatening disorder caused by aerobic and anaerobic bacterial infection. We report a case of genital infection as the initial warning sign of acute myeloid leukemia. We were able to prevent progression to Fournier's gangrene in our patient by immediate intensive therapy with incision, blood transfusions and intravenous administration of antibiotics. This case suggests that hematologists and dermatologists should keep in mind that genital infection can be a first sign of hematologic malignancy

Sieving of aerosol particles with metal screens

Metal screens with uniform micrometer-sized opening were employed to sieve aerosol particles by suppressing the adhesion of particles smaller than the openings. The collection efficiencies of monodispersed polystyrene latex (PSL) particles were experimentally determined using the metal screens with 1.2, 1.8, 2.5, and 4.2 μm openings at various filtration velocities. The particles smaller than the mesh opening adhered on the metal screen at a low filtration velocity, but the bounce-off of particles on the mesh surface suppressed the adhesion at a high velocity. As a result, we found that the adhesion of PSL particles larger than 0.3 μm mostly suppressed at a filtration velocity higher than 10 m s−1 and therefore we can sieve aerosol particles according to the opening size of metal screens. We also found that the particle number concentration could be determined by measuring the increase in pressure drop since the clogging of metal screen openings takes place by the individual particles. © 2016 American Association for Aerosol Research © 2016 American Association for Aerosol Research.Embargo Period 12 month

Photoallergic Contact Dermatitis due to Ketoprofen and Hydrogenated Rosin Glycerol Ester

A topical application of a nonsteroidal anti-inflammatory drug (NSAID) may induct an adverse reaction of photoallergic contact dermatitis. The occlusive usage may provoke concomitant photoallergic sensitizations to an NSAID and other ingredients. We describe a 58-year-old woman with photoallergic contact dermatitis from ketoprofen and hydrogenated rosin glycerol ester in the applied compress. Our case indicates that photopatch testing with all ingredients is required to verify the actual photoallergen(s)

Effects of cosmetics on quality of life of patients receiving cosmetic dermatology treatment

Some cosmeceuticals, e.g., moisturizer and sunscreen, are widely used in dermatological therapies. We investigated the impact of cosmetics on the quality of life of female patients who received cosmetic dermatology treatment in our department. Twenty-seven female patients, aged 21-69 (mean: 41.2), participated. A moisturizer and sunscreen of SPF50＋ and PA＋＋＋ were provided. Assessments were performed at the baseline and 4 weeks using Skindex-16 and a questionnaire. There were significant improvements in symptoms (p＜0.01), emotions (p＜0.001), functioning (p＜0.05), and global scale scores (p＜0.001) at 4weeks compared with the baseline. The combination of the two cosmetics was well tolerated and favorably affected the QOL of female cosmetic dermatology patients, leading to significant improvements
