Quantities of steroid cream or ointment to use for a child will still be expressed as adult fingertip units (see Table 9.1). In general, the lowest strength of topical corticosteroid should be prescribed to young children as systemic side-effects such as growth retardation are more commonly seen in children. For this reason it is common for children to have steroid holidays when only emollients are used to control the... 

In the case of medicines for cutaneous use (e.g. dermatology medicines), the concentration of the active substance is usually written as a percentage. The prescriber writes the amount and the frequency with which the dermatologic medicine has to be applied. The doctor usually writes the part of the body on which the patient should apply the preparation. In this way the pharmacist can check whether the prescribed amount is sufficient. Furthermore it is also important to know whether the cutaneous medicine has to be applied thickly (liberally) or thinly. A practical device for dosing a cutaneous preparation is the fingertip unit (FTU), see Table 12.3. In Germany, the Neues Rezeptur-Formularium for doctors [7] contains a useful outline figure for the prescriber to mark the area of application (Fig. 2.7). 

If the cutaneous preparation is going to be applied because of its physical properties, such as the prevention of dehydration, ample application is desirable. If the preparation is mainly acting by its active substance, the amount to be applied is expressed in fingertip units to prevent underdosing when the patient is told to apply thin , as well as overdosing [9],... 

Motifs in DNA- and RNA-binding proteins whose amino acids are folded into a single structural unit around a zinc atom. In the classic zinc Anger, one zinc atom is bound to two cysteines and two histidines. In between the cysteines and histidines are 12 residues that form a DNA-binding fingertip. By variations in the composition of the sequences in the fingertip... 

Why did it end Basically because the bean-counters in ICI couldn t see a return on their investment. Joe was never really at home in an industrial environment, not that The Frythe could even remotely be termed industrial in ambience. He was an academic to his fingertips and flourished in that atmosphere, as indeed he had done at Cambridge, and did later at Sussex University when he headed the Nitrogen Fixation Unit of the Agricultural Research Council. He never cultivated relationships within the company, finding the political side of life distasteful. Consequently, he was unprotected when a chill wind began to blow. 

The word unit is defined as a precisely stated quantity in terms of which other quantities of the same kind can he stated. For each dimension, there is a need for one or more reference amounts in order to describe quantitatively the physical properties of some object or material. For example, the dimension of length has been measured in units of miles, metres, feet, the distance from a person s nose to fingertip, and many others. We measure time in units of seconds, minutes, hours, months, and so on.
