rash(rash), Avoid the redundant phrase skin rash.
HRASA gene on chromosome 11p15.5 belonging to the Ras oncogene family, the protein products of which bind GTP and GDP, have intrinsic GTPase activity, and play key roles in signal transduction. HRAS cycles between de- and re-palmitoylation, a reaction that regulates its rapid exchange between the plasma membrane and the Golgi apparatus.
Defects in HRAS are associated with an increased risk of bladder cancer, Hürthle cell carcinoma of thyroid, and oral squamous cell carcinoma. HRAS mutations cause faciocutaneoskeletal syndrome and congenital myopathy with excess of muscle spindles—a variant of Costello syndrome.
rashAn exanthem or skin eruption. See Butterfly rash, Heliotrope rash, Herpetiform rash, Hot tub rash, Maculopapular rash, Morbilliform rash. Cf Petechia, Purpura.
rash(rash) [Fr. rasche, skin eruption]
Assessments are made of the location and characteristics of the lesion: color; size (height and diameter); pattern, whether discrete or coalesced; and any secondary changes (crusting, scaling, lichenification). Associated symptoms such as pruritus or discomfort, temporal elements, history of known allergies, drugs used, and contacts with communicable diseases during prior 2-week period also are assessed. Suspected drugs are discontinued, and the potential communicable disease patient is isolated and assessed. Cool compresses are applied to relieve itching. Topical preparations and dressings are applied and systemic medications administered as prescribed. The patient is instructed to keep hands clean and nails short and even, and to avoid scratching. The patient also is taught about the treatment regimen, its actions, and its side effects and evaluates for desired effects and side effects.
Treatment is symptomatic. Diapers should be changed frequently. If washable cloth diapers are used, they should be thoroughly washed and rinsed; occlusive plastic pants should not be used over diapers; the perianal and genital areas should be washed with warm water and mild, nonperfumed soap. If these measures and the application of a bland protective agent (such as zinc oxide paste) do not promote healing, then a small amount of 0.5% to 1% topical hydrocortisone cream should be applied to the area after each diaper change until the rash has completely resolved.
