HRAS

A 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.

Molecular pathology
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.

rash

(rash) [Fr. rasche, skin eruption]
A general term for any eruption that appears on the skin transiently (as opposed to durable skin lesions such as scars, tattoos, or moles). Synonym: exanthem

Patient care

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.

butterfly rash

A rash on both cheeks joined by an extension across the bridge of the nose. It is seen in systemic lupus erythematosus, esp. after the patient's face has been exposed to sunlight, and in seborrheic dermatitis, tuberous sclerosis, and dermatomyositis.

DIAPER RASH

diaper rash

Irritant contact dermatitis as a reaction to friction, maceration, and prolonged contact with urine, feces, soap retained in diapers, and topical preparations. A persistent diaper rash may be colonized by yeast or bacteria. Synonym: diaper dermatitis See: illustration

Treatment

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.

A. My own daughter was yeasty from whatever they do to newborns in the hospital and I battled it ever day until I started taking garlic gel tabs. Because I breasfed her she got all the benefits of it and her bottom cleared right up.
