Biomarkers by Immunochemistry: Epidermal Differentiation
Time Frame: At end of treatment
|
3 skin biopsies (punch biopsies of 3 mm) per participant were taken on Day 29 after the clinical scoring and ultrasound measurement.

Biomarkers by Immunochemistry: Epidermal Proliferation
Time Frame: At end of treatment
|
3 skin biopsies (punch biopsies of 3 mm) per participant were taken on Day 29 after the clinical scoring and ultrasound measurement. By measurement of the cell-cycle marker, Ki-67 protein, an evaluation of the degree of skin cell proliferation and thereby epidermal proliferation could be obtained. Cells counted per mm^2 were cells that were positive for the indicated biomarker. |
At end of treatment

Pathology and Histology by Treatment
Time Frame: At end of treatment
|
Skin biopsies were taken on Day 29. The evaluation of immunohistochemical sections were performed on cross sections of the skin tissue. The same pathologist did all evaluations, and samples were masked to ensure a blind fashion study. The extent of the following parameters were measured in scored semi-quantitatively (semi) on blinded haematoxylin and eosin (HE) sections. Semi-quantitative scoring was categorized as No (0), mild (1), moderate (2), marked (3) or severe (4). In evaluating the morphology of epidermis (Stratum corneum and Stratum granulosum) the tissue was classified by the characteristics seen below:

Pathology and Histology by Treatment: Epidermal Thickness
Time Frame: At end of treatment
|
Skin biopsies were taken on Day 29.
The evaluation of immunohistochemical sections were performed on cross sections of the skin tissue.
The same pathologist did all evaluations, and samples were masked to ensure a blind fashion study.
In evaluating the morphology of epidermis (Stratum corneum and Stratum granulosum), the tissue was classified by the characteristic epidermal thickness.
This was measured in the absolute number of µm measured on blinded haematoxylin and eosin (HE) sections..

Pathology and Histology by Treatment: Frequency of Neutrophil Abscesses
Time Frame: At end of treatment
|
Skin biopsies were taken on Day 29. The evaluation of immunohistochemical sections were performed on cross sections of the skin tissue. The same pathologist did all evaluations, and samples were masked to ensure a blind fashion study. In evaluating the morphology of epidermis (Stratum corneum and Stratum granulosum), the tissue was classified by the characteristic of frequency of neutrophil microabscesses (Monroe´s abscess). This was measured in absolute number of cells that were positive for the marker on blinded haematoxylin and eosin (HE) sections. |
