It is well documented that following thermal burns injury the development of hypertrophic scars and keloid (HSK) ranges between 40 to 90%. on the other hand It is well documented that cryosurgery wounds generally heal with minimal tissue contraction, resulting in good cosmetic results and with minimal complications.

The Aim of the study is To specify the burn and cryosurgery blister fluid for proteins, cytokines and cells and To compare between the above data regarding possible proteins, cytokines and cells, in regard to their possible effect on scarring and wound healing.

Also to Identify those components which are present only in the cryosurgery blister and which might have an anti-scarring effect and to characterize them biochemically.

Further study details as provided by Yaron Har-Shai, Carmel Medical Center:

Primary Outcome Measures:
  • comparison of inflamation cells and proteins (proteomic evaluation) between blisters caused by heat and blisters caused by cryo injury [ Time Frame: at time of sampling. ]

    the protein evaluation and comparison is achieved by the use of proteomic study which evaluate the quantity of about 700 different proteins in the fluid of the different blisters (heat blisters compared to "cryo" blisters).

    we also evaluate the differences in quntities between the inflamation cells in each sample.

Biospecimen Retention:   Samples With DNA
blister fluid of kryosurgery and second degree burns Following the results of the above study a further extension of the study is progressing in which the identification of the cell population in the blister fluid following intralesional cryosurgery of keloid scars is examined
