Corticosteroid responsive dermatoses meaning

Different formulations have been developed in an effort to enhance the delivery of topical corticosteroids. Betamethasone valerate in a foam had superior efficacy for scalp psoriasis and was preferred by patients when compared with betamethasone valerate lotion [ 20 ]. The foam becomes a liquid on contact with skin and is also well tolerated by patients with trunk and extremity psoriasis [ 21 ]. A clobetasol propionate spray is also available; like foams, sprays are easy to apply to large areas [ 22 ]. The main advantage of these newer preparations is likely greater patient acceptance, which may translate into greater adherence; the main disadvantage is cost.

Treat infection if present; discontinue if infection persists or worsens. Do not use near eyes, or on diaper dermatitis or pre-existing skin atrophy. Do not use fluorinated steroids longer than 1 week on the face. Avoid abrupt cessation in chronic use. Systemic absorption increased by broken or inflamed skin, prolonged use, application to large surface area, or use of occlusive dressings. Occlude only if necessary; do not occlude higher potency products. Monitor adrenal function in children if a high potency product or occlusion is used, and in adults if more than 50g weekly of a high potency product is used. Discontinue or reduce dose or potency if HPA axis suppression, Cushing's syndrome, hyperglycemia, glucosuria, or irritation occurs. Use lowest effective dose and potency (esp. in children). Use caution if applying to face or body folds. Do not use continuously or for prophylaxis. Foams are flammable. Reevaluate periodically. Pregnancy (). Nursing mothers.

Use of QVAR with a spacer device in children less than 5 years of age is not recommended. In vitro dose characterization studies were performed with QVAR 40 mcg/actuation with the OptiChamber and AeroChamber Plus ® spacer utilizing inspiratory flows representative of children under 5 years old. These studies indicated that the amount of medication delivered through the spacing device decreased rapidly with increasing wait times of 5 to 10 seconds as shown in Table 2. If QVAR is used with a spacer device, it is important to inhale immediately.

Methotrexate is given weekly as an intramuscular injection of 15 to 25 mg. Side effects are rare and include leukopenia and hypersensitivity interstitial pneumonitis. Hepatic fibrosis is the most severe potential sequela of long-term therapy. Patients with concomitant alcohol abuse and/or morbid obesity are more likely to develop hepatic fibrosis and therefore should not be treated with methotrexate. It is prudent to obtain a baseline chest radiograph and to monitor complete blood count, liver function and renal function every two weeks until the patient is receiving oral therapy, and every one to three months thereafter. Before methotrexate therapy is initiated, the risks of treatment and the possible need for a liver biopsy should be discussed with the patient.

In a landmark paper, Liggins and Howie showed that a single course of antenatal corticosteroid therapy administered to women at risk for preterm delivery (PTD) reduced the incidence and severity of respiratory distress syndrome (RDS) and mortality in offspring [ 1 ]. Over two dozen randomized trials have confirmed these findings [ 2 ]. Subsequent trials have also shown that antenatal corticosteroid therapy improves circulatory stability in preterm neonates, resulting in lower rates of intraventricular hemorrhage (IVH) and necrotizing enterocolitis compared with unexposed preterm neonates.
