Hailey-Hailey Disease – A Case Report

Abstract

Hailey-Hailey disease (HHD) is a rare autosomal dominant skin condition discovered in 1939 by Hailey brothers. Prevalence is found to be around 1 in 50,000 and is relatively uncommon in India. First onset of disease occurs between 20 to 40 years of age, usually presented in the 3rd and 4th decades of life. Here, we report a case of a 50-year-old female who presented with clinical features of the HHD and showed greater response to the treatment.

Flammability, thermal stability, and mechanical properties of ethylene‐propylene‐diene monomer/polypropylene composites filled with intumescent flame retardant and inorganic synergists

“…In recent years, a novel flame‐retardant method just like inorganic particles applies to polymer and significantly affects the fire retardancy, thermal, mechanical, and catalytic properties of the polymer matrix 14–16 . Aluminum hydroxide, chlorinated polyethylene, decabromobiphenyl oxide, and expanded graphite (EG) were mixed with EPDM and improved the thermal stability and flame retardant of the composites 17 . The flame‐retardant composites were prepared by incorporating the microcapsule layered double hydroxides into ethylene vinyl acetate and achieved a LOI of 25.5% and an UL‐94 V‐1 rating 18 .…”
