Visually first signs of improvement of atrophic scars can be noticed in 6-8 weeks after injection of APCPB and gradually progress during 6 months. The atrophy of epithelium, hyperkeratosis, sclerosis of all dermis layers with smoothing of papillae, reduction of number of blood vessels and skin appendages were found before treatment by method of light mi-croscopy. In all observations after injection of APCPB in a connective tissue, which replaces of dermis, an increase of number of vessels at the expense of processes of neoangiogenesis, leukocytic infiltration reduction, thinning and ordering of arrangement of collagen and elastin fibers were detected. These results give a chance for more successful application of cosmetology procedures for correction of these defects of skin.展开更多

Our goal was to compare the frequency of striae gravidarum in women who gave preterm birth and women who gave term birth. Methods: A case-control study was conducted in women who gave preterm birth (n = 66) and age matched women who gave term birth (n = 68). Cases and controls were recruited from puerperal women consequently seen at delivery wards of perinatology unit. All women underwent dermatologic examination in terms of SG blindly to theirs gestational weeks of delivery. The frequency of SG was compared in all groups. Results: The frequency of SG was 63.6% in women with preterm birth and 54.4% in women with term birth (p = 0.278). SG is five times more common in late preterm group than in women with term group, but this difference was not statistically significant [(p = 0.227, OR: 5.02, CI 95% (0.5 - 44.0)]. The rate of preventive cream usage was not statistically different in women with SG and without SG (p = 0.245). Conclusions: It seems that there was no statistically significant association between the risk of preterm labor and the presence of striae gravidarum. Larger prospective observational studies are needed to state expressly the probable clinical association between the presence of SG and preterm delivery.展开更多

Hormonal changes,overstretched skin, and structural and functional changes in the skin may be crucial factors in the development of SD. Therapy aims to stimulate dermal collagen synthesis and improve skin texture. Mainstream treatments include topical medications, chemical peeling, laser and radiofrequency therapy, microdermabrasion, microneedle therapy, and filler injection therapy. In the present review, we summarize current perspectives on the pathogenesis and clinical therapy of SD.展开更多
