Occlusive therapy is highly effective. Apply the topical steroids mentioned above under subacute eczema and cover with a plastic wrap such as Saran wrap. The plastic dressing does not have to be airtight. Secure the dressing with tape on either end. A sock will hold the plastic dressing against a foot. The dressing may stay on for 2 hours or overnight. Remove the dressing and apply an emollient or more medication. It is not necessary to wash the skin each time a plastic dressing is applied. The appearance of pustules indicates a secondary infection. Stop treatment and prescribe topical or oral antibiotics for this side effect of occlusive therapy.
Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more  or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram.  [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography .  : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity.
