Active clinical trials for "Keloid"

The wound healing is a process occurring in response to dermal injury. The resulting scar may have various characteristics ranging from fine-line and asymptomatic to hypertrophic scars and keloids. Prevention or early treatment of pathological scars is the most appropriate approach. Among available remedies, gels and patches containing onion extract and allantoin have been demonstrated to be safe and effective in patients with scars of various origins and severity. One of the most used natural products is a patch containing allium cepa and allantoin licensed for treatment of the scars including keloids. However, up to date, no controlled studies have evaluated the effects of such a device in women who have undergone Cesarean delivery. Therefore, the aim of this study was to investigate the effects of this patch on Cesarean section (C-section) scars.

Skin keloids are common dermatological conditions that can lead to physical limitations, functional impairments, and deformities. Beyond the physiological implications, the aesthetic ramifications of keloids can also result in significant psychological distress, including anxiety and depression, causing both physical and emotional suffering to the affected individuals. The incidence of keloids is high, characterized by their chronicity, resistance to treatment, and high recurrence rate. They have become one of the most challenging conditions to treat across burn surgery, plastic surgery, and dermatology disciplines. The lack of standardized clinical treatment guidelines globally, combined with an absence of a well-defined standardized evaluation system, means that the effectiveness of various treatments is not consistently and objectively assessed, creating significant challenges in clinical applications. This project integrates traditional high-frequency ultrasound with cutting-edge technologies like real-time shear wave elastography and ultra-micro blood flow imaging. By using multimodal ultrasound, investigators aim to observe the therapeutic response of 90Sr-90Y patch treatment on skin keloids. Investigators seek to determine the objectivity and quantification role of multimodal ultrasound data and indicators in assessing keloid severity, including blood flow information and elasticity hardness. Another goal is to obtain quantitative data on keloid thickness, volume, stiffness, and microvascular distribution before and after treatment to monitor the therapy response. This would address the current limitations of subjective keloid scoring scales. It would also serve as an objective assessment standard for precise diagnosis, treatment, and follow-up of keloids in a clinical setting, thereby standardizing the clinical diagnosis and treatment of keloids.

A pilot study will be conducted on 2 type of subjects, one with plastic surgery scar with a randomization of laser treated portions, and other with keloid excision scar with a complete laser treatment. The aim is to evaluate the infra-red diode laser influence on keloid recurrence and scar prevention. The keloid recurrence rate will be evaluated at each visit, and the scar prevention in plastic surgery will be evaluated comparing laser treated portion and non-treated portion.

Keloids and hypertrophic scars are not major illness. However, their effects can be from causing pain and itch which substantially interfere daily activity to as severe as causing deformity and other functional impairment. For standard surgical wounds, taking median sternotomy wounds from open heart surgery and lower abdominal wounds from gynecological wounds for example, the incidence of these problems can be from 10% to 60%. To prevent or treat these problems, physicians have used many modalities. One of the most convenient, most cost-effective and most non-invasive methods for patients is using dressings like silicone sheets, silicone gels or paper tapes, which is on the list of 1st line choices of an international recommendation. According to a literature review, most of the previous studies on similar topics are either of small sample size, on non-standard wounds or comparisons between wounds on different patient groups. The methodologies of previous studies are thus not vigorous enough. To get the highest level of evidence on selecting the best dressings for preventing and treating keloids and hypertrophic scars, we will recruit about 75 patients and apply two selected dressings on each halves of their standard surgical wounds to compare their differences. The investigators hope the result of this study can help us find the best modality to use and can contribute to the welfare of our future patients.

Despite their benign nature, keloids may constitute a severe aesthetic, and in some cases, functional problem which translates to various repercussions on person's quality of life, including much stress and insecurities. Keloids are mostly observed between the ages of 10 and 30. Although keloid is a common condition and the investigators can make assumptions about those living with keloids, the investigators do not know the actual impact of the illness on the overall performance of patients' and how this disease, day to day, is impacting their lives. The investigators are conducting this study, aimed to investigate the psychosocial impact of keloid on daily life. Information is collected anonymously. You must be 18 years of age or older to take this survey. Parents can respond on behalf of their children who are not 18 years of age yet. The online survey will take 20-30 minutes to complete.

SCARWARS study deals with the first on-human evaluation of a compressive device dedicated to the prevention of keloïd scars recurrence after surgery. The tested device is made with clinical grade silicon. SCARWARS is a monocentric study. 27 patients will be include and follow during one year. The primary outcome of this study is the number of keloid recurrence after treatment.

This prospective study evaluates the outcome of surgical excision with adjuvant high-dose-rate brachytherapy for the treatment of recalcitrant keloids. Main outcomes are recurrence rate, scar quality and physical complaints.

Most children with cancer need a central venous catheter. These catheters are typically placed on the anterior thorax, where the risk of hypertrophic scarring and keloid development is greatly enhanced. A significant part of the children who have survived childhood cancer are troubled by their scars. Topical glucocorticoid treatment is known to induce a reduction of the collagen in the connective tissue. The investigators hypothesize that treatment with topical glucocorticoids for one week before and three weeks after removal of a central venous catheter, will reduce the formation of hypertrophic scarring and keloid development in children.

The purpose of this study is to identify the gene or genes responsible for keloid formation. Keloids are raised scars on the skin that form after a minor injury. A tendency to develop keloids often runs in families, suggesting a possible genetic basis. People who have had a classic (butterfly-shaped or wound-overflowing) keloid for at least one year may be eligible for this study. In addition to these probands (original participants), family members over 12 years of age who have either classic or non-classic keloids and those 18 years of age or older without keloids may participate. Probands and family members with keloids will have a medical history focusing on skin problems-particularly keloids-and a skin examination. In some cases, with the subject s permission, photos of the keloids will be taken. All participants will have 35 milliliters (about 2 tablespoons) of blood drawn for DNA (genetic) testing and for measurement of blood proteins, including cytokines, which can affect other tissues and cause scarring. Part of the blood sample will be used for additional genetic studies unrelated to keloids. The samples will be coded for confidentiality.

Radiation therapy has been, and is being used in treatment of patients with keloid. Radiation is typically used as an adjunct to surgery in order to reduce the recurrence rate of keloid. Radiation therapy is not free of long term side effects. Radiation Therapy is known to cause secondary cancers. The investigators also do not have a good understanding as to how effective radiation therapy is in preventing recurrence of keloid. Purposes of this study are to determine the long term safety as well as efficacy of radiation therapy when used for treatment of keloid.
