Active clinical trials for "Cicatrix"

Case control study of patients with and without restenosis to demonstrate the link between in-stent restenosis and an excessive skin healing. Patients will undergo skin biopsy and blood sample tests to search for a relationship between both processes and for the identification of biomarkers and therapeutic targets.

To determine whether silicone gel is effective at preventing or minimizing scar formation after eyelid surgery.

In this study the investigators intend to determine the impact of fractional CO2 laser treatment on the edges of a fresh wound during surgical area closure on thin skin (e.g. face, hands, arms, thorax, etc.) and on thick skin (abdominoplasty procedure) on scar formation. The investigators will also evaluate the effect of shallow fractional laser treatment versus deep parameters settings. If effective treatments could be performed at time of surgery, this would result in both time and cost saving to the patient and to the healthcare system and will improve patient's self-image post surgeries.

The purpose of this study is to measure the effectiveness of the RevLite Laser in the treatment of both fresh surgical scars and mature/older scars.

The purpose of this study is to assess the efficacy of skin anesthesia using fractional laser assisted delivery of articaine hydrochloride 40 mg/ml and epinephrine 10 µg/ml solution (AHES) compared to standard anesthesia with topical eutectic mixture of lidocaine 25 mg/g and prilocaine 25 mg/g cream (EMLA cream) prior to ablative fractional laser treatment of acne scars and traumatic scars.

This Phase II, double-blind, randomized, placebo-controlled pilot study is designed to determine whether injection of autologous fibroblasts can increase the mobility (decrease the restriction) of burn scars. The study will assess the effects of azficel-T (autologous fibroblasts) in subjects who have a unilateral burn scar that is no deeper than the fascia (i.e., underlying structures including ligament, tendon, muscle, and bone must not contribute to the restriction) and that is either: An axillary scar causing 20-60% restriction of shoulder adduction An anterior elbow scar causing 20-60% restriction of elbow extension A dorsal or palmar lesion of a single finger causing 20-60% restriction of flexion or extension Subjects will each receive 2 injections of azficel-T or placebo administered 14 days (± 7 days) apart (depending on cell availability) and will be followed for efficacy (including range of motion measurements, scar pain and ability to perform activities) to Visit 7 and for safety to Visit 9 at 1 year.

Evaluation of cesarean scar using saline-infused sonography in women with history of cesarean scar pregnancy.

Cutaneous scarring after elective surgery is a concern for surgeons of all types, perhaps even more so to plastic surgeons. Cautery is often used on the "cut" setting to make or extend incisions; however very few studies have looked at the results of these scars. The investigators' study aims are to compare standard scalpel incisions versus cautery incisions and to objectively compare the resultant scars in a prospective, randomized, controlled fashion.

Post acne scarring is a common complication of acne. Cosmetic appearance of the post acne facial scarring can be improved by various methods. Among the procedural methods microneedling (1) is a novel and a promising option. It is a minimally invasive day care procedure for the management of atrophic acne scars. Topical tazarotene 0.1% gel is an effective medical method in the management of acne vulgaris and macular acne scars (2, 3). Based on its mechanism of action and role in collagen synthesis, topical tazarotene is a logical choice to investigate for the management of atrophic post acne scars. This is a pilot study comparing microneedling and topical tazarotene for the treatment of atrophic post acne scarring in regard to extent and rapidity of improvement, patient satisfaction and any adverse events if any. Thirty six subjects with grade 2 to grade 4 atrophic post acne scars, classified on the basis of Goodman's Qualitative classification (4) criteria will be recruited. Goodman's qualitative and quantitative acne scarring grading system scoring will be performed for the assessment of severity of acne scarring at baseline. The face of each patient will be randomized for monthly microneedling on one side and topical tazarotene 0.1 % gel once a day local application on opposite side, using computer generated random number table. Follow ups will be done at every month until treatment completion (3 months) and 3 months after the last treatment session. Goodman's qualitative and quantitative acne scarring grading system scoring will be performed at 3rd and 6th month follow up visits. An improvement by two grades will be considered as excellent, one grade will be rated as good and no up gradation will be labelled as poor response. Patients will be also assessed by a blinded observer for clinical improvement and scored on a scale of 0 (no improvement) to 10 (maximum) at 3rd and 6th month follow up visits with the help of serial photographs taken under consistent background, position and lighting. All patients will be instructed to assess themselves using Patients' Global Assessment Score 0 (no response) to 10 (maximum) at 3rd and 6th month follow up visits. The investigators hope the outcome of the present study may propose a newer medical modality for acne scarring, i.e topical tazarotene 0.1% gel, which can be used at home, obviating the need for physician dependant microneedling procedure.

Background Scarring typically occurs after trauma, burn injury or surgery. Hypertrophic scarring presents as raised, red and itchy lesions which variably respond to various treatment modalities, such as corticosteroids, pressure garments, laser therapy, the use of silicone sheets and radiotherapy. Kynurenine, or "Fibrostop 1" (FS1), and its further breakdown products, such as kynurenic acid, or "Fibrostop 2" (FS2), are endogenous products found in many systems and have shown potential in reducing scar formation in animal studies. The aim of study is to evaluate the safety and tolerability of FS2 cream applied to the skin of healthy human subjects.
