Skin drag test

The skin should be inspected for any signs of trauma or surgical scars. Skin lesions should be noted. The erythema test and skin drag test can be performed as possible indicators of somatic dysfunction. 

Palpation is best performed with the patient prone on a table and the physician standing at the side of the table facing the patient. The erythema test may be performed at this time, as may the skin drag test. When these tests are positive they are indicators or somatic dysfunction as explained in Chapter 8. 

This equation is an inverted form of the core pressure drop in Eq. 17.65. For the isothermal pressure drop data, p, = p = l/(l/p)m. The friction factor thus determined includes the effects of skin friction, form drag, and local flow contraction and expansion losses, if any, within the core. Tests are repeated with different flow rates on the unknown side to cover the desired range of the Reynolds number. The experimental uncertainty in the/factor is usually within 5 percent when Ap is measured accurately within 1 percent. 

Fig. 6 Pustular drug eruption (AGEP) disseminated pustules cover the skin. Histologically, the pustules are intraepidermal and nonfollicular. A patch test reaction to the eliciting drags can lead to a pustular reaction as well for details see text...

Skin testing with the three platinum drags has been employed to identify at-risk patients and predict platinum hypersensitivity. As yet, skin testing with the drugs has not found widespread acceptance and application as a routine diagnostic procedure. 

A 12 step, 6 h desensitization protocol for carboplatin has been successfully employed in skin test-positive patients hypersensitive to the drag.
