This is an 18-month follow-up study of the 19 treated psoriatic cases, reported previously.1
Materials and Methods
Because many requests have been received for detailed method description following the previous publication,1 this text intends to satisfy such requests. One-quarter per cent triamcinolone diacetate (2.5 mg. per cc.) suspension is obtained by mixing 10 parts of the commercially available triamcinolone diacetate suspension (25 mg. per cc.) with 45 parts of normal saline and 45 parts of 1% procaine. To obtain a homogenous suspension, the syringe is turned a few times. A few minims of 1% procaine is injected with a 26 gauge, ⅜ inch long needle at the periphery of the lesion. Then the suspension is infiltrated without pressure subdermally under the lesion in the upper layer of the loose subcutaneous tissue with an appropriate needle. For a lesion of 25 mm. in diameter, 2 cc. suspension is sufficient.
