Safety assessment of the prophylactic use of silicone gel sheets (Lady Care®) for the prevention of hypertrophic scars following caesarean section.

This study aimed to investigate the side effects of silicone gel sheet (Lady Care®) and evaluate its prophylactic efficacy in preventing abnormal scarring. Sixty women who underwent caesarean section were recruited from September 2016 to September 2017 in this prospective study. Lady Care® was applied from the 2nd to the 6th postoperative months. Side effects of Lady Care® were evaluated through medical examinations and questionnaires. A plastic surgeon diagnosed abnormal scarring. Pruritus was diagnosed in 25 (47.2%) patients; folliculitis, four (7.5%); dry skin, four (7.5%); contact dermatitis, three (5.7%); wound infection, two (3.8%); and epidermolysis, one (1.9%), albeit with mild severity. Following Lady Care® application, no abnormal scarring and mild hypertrophic scarring was observed in 32 (64.0%) and 18 (36.0%) patients respectively. Of seven patients with pre-existing hypertrophic scars, only two showed hypertrophic scarring after Lady Care® application. Our findings support the safety and prophylactic efficacy of Lady Care®.Impact StatementWhat is already known on this subject? The incidence of abnormal scarring, i.e. keloid or hypertrophic scar formation after caesarean section (CS) is reported to be ∼41%. Abnormal or excessive scar formation can lead to functional limitations, pruritus, pain and cosmetic issues. Studies have also shown a prophylactic effect of the application of silicone materials against the development of hypertrophic and keloid scars, though prohibitive cost and lack of adhesiveness of such gel sheets are known factors limiting their usage.What the results of this study add? The new silicone gel sheet 'Lady Care®' has strong adhesive properties and is consequently not easily peeled off. Furthermore, it is easy to use and economically efficient.What the implications are of these findings for clinical practice and/or further research? This is the first clinical trial on the application of Lady Care® silicone gel sheet for the prevention of CS scarring. Our findings support the safety and prophylactic efficacy of Lady Care®.

Assessment of the Combined Efficacy of Needling and the Use of Silicone Gel in the Treatment of C-Section and Other Surgical Hypertrophic Scars and Keloids.

OBJECTIVE: To evaluate the individual effectiveness of needling therapy using the Dermapen (Dermapen, Salt Lake City, Utah) and topical therapy with silicone gel (Kelo-cote, Sinclair Pharma, London, England), and their combined effectiveness for the treatment of linear surgical scars, hypertrophic scars, and keloids. MATERIALS AND METHODS: Twenty patients were randomly selected and equally divided into 2 groups (A and B), with each group of 10 including 6 patients with keloids and 4 with hypertrophic scars. Treatment assignments were random. In group A, the entire scar was treated by skin needling, with silicone gel applied to half of the scar. Patients in group B were treated with silicone gel on the whole scar, with only half of the scar also treated with skin needling. During follow-up visits, clinical photographs, evaluation of the scars' thickness, skin ultrasound, and modified Vancouver Scar Scale were performed. RESULTS: Group A showed an average improvement of 68% (P < .01) on the half of the scar with the combination treatment (skin needling plus silicone gel) compared with a 52% improvement on the half of the scar that was treated with only skin needling. Group B showed an average improvement of 63% (P < .01) where the combination treatment was performed, compared with 47% improvement on the area treated with only the silicone gel. CONCLUSIONS: In conclusion, the combination of these 2 treatments is safe and effective for the treatment of hypertrophic scars and keloids. These modalities achieved favorable results with each patient adhering to the study paramenters.

Ultrasound assessment of scald scars in Asian children receiving pressure garment therapy.

BACKGROUND/PURPOSE: Scar formation after scald injury in children is managed commonly by application of pressure garment. The duration of the treatment depends on clinical assessment. The objective of the study was to evaluate the efficacy of the pressure garment therapy and to correlate the clinical assessment scar thickness with ultrasound measurement. METHODS: Prospective study of children with hypertrophic scars receiving pressure garment therapy was carried out between 1993 and 1998. The scars were mapped with paper cutting. Representative scar sites were scored clinically according to Vancouver General Hospital Burn Assessment Scale (pigmentation, vascularity, pliability, height, pain, itchiness). Blind to the clinical results, 2 radiologists measured the scar thickness of the same sites with ultrasonography (5 to 10 MHz transducer, General Electric LOGIQ 500). The correlation between the clinical scores and ultrasound measurement of scar thickness were analysed using analysis of variance (ANOVA). RESULTS: The median age of 58 children with scald injury (M:F = 36:22) was 2.8 years (0.5 to 15.8 years). The mean percentage of scald was 8.8% (24% had scald area >10%). In addition, there were 5 children with burn from naked flame and 9 children with keloid secondary to surgical incisions. With pressure garment therapy, the scar thickness reached a plateau 1 (1/2) years after the injury and began to decline gradually thereafter. The clinical estimation of scar thickness correlated well with the ultrasound measurement (ANOVA, P =.003, Adjusted R square = 0.99). The accuracy rate of clinical thickness estimation was 67%. Overestimation and underestimation accounted for 15% and 18%, respectively. There also was good correlation between total clinical score and the ultrasound measurement (ANOVA, P <.001). CONCLUSIONS: In children with scald injury, the pressure garment needs to be continued for a minimum of 1 year. Ultrasound measurement correlates well with overall score of the Vancouver General Hospital Burn Assessment Scale but not individual components of the scoring system except wound height.
