Single-center, open-label, baseline-controlled, pilot study evaluating the use of a Nonablative 1470 nm laser for the treatment of androgenetic alopecia and scarring alopecia.
In women with one previous caesarean, the choice of mode of delivery is determined by a shared decision-making process between the women and the obstetrician, with the two options being a trial of labour after caesarean (TOLAC) or an elective repeat caesarean delivery (ERCD). To date, the scientific literature has reported of higher perinatal morbidity-mortality with TOLAC, although with low absolute risks and discordant results about maternal morbidity-mortality. These studies suffer from limitations, as they include women with more than one previous caesarean or with high rates of failed TOLAC, which are two risk factors for uterine rupture, and the definition of planned versus effective mode of delivery is not precise in most studies. However, scientific societies recommend that most women with one previous caesarean should be offered TOLAC because of the low absolute perinatal risk of this option and the high maternal and perinatal risk associated with an ERCD in the short- and long-term. Conversely, the investigators hypothesise that TOLAC would be not inferior to ERCD in women with one previous caesarean in terms of perinatal morbidity-mortality.
Vocal Folds scarring (whether congenitally or following phonosurgery) can result in a range of symptoms depending on severity and extent, such as hoarseness, breathy voice, increased effort to speak, and voice fatigue. The inability to phonate normally causes both physical and psychological disability, especially for professional communicators (teachers, tradesmen, singers, etc.). There are several therapies currently available but these are often disappointing, as the great complexity of vocal fold microstructure hinders the development of effective therapy. Thus, identification of innovative strategies able to improve vibrational mechanical properties of vocal folds remains an important clinical challenge. Autologous Adipose-Derived Stromal Vascular Fraction (ADSVF) is recognized as an easily accessible source of cells displaying angiogenic, anti-inflammatory, immunomodulatory and regenerative properties. Recent experimental and clinical reports also supported the anti-fibrotic potential of ADVSF, mainly attributed to the mesenchymal stem/stromal cell subset. Safety in humans has already been confirmed in several studies, including our previous clinical trial (ClinicalTrials.gov NCT0262246; EudraCT number: 2015-000238-31). The main objective of this phase I/II trial was to measure for the first time the safety and tolerability of autologous ADSVF local injections in patients with scarred vocal folds. No severe adverse events occurred: only some minor adverse events were reported. Moreover, Voice Handicap Index was improved in all patients with a mean improvement from baseline of 40.1/120 and seven patients were considered as responders, defined as an improvement ≥ 18 points. Based on these observations, we hypothesized that the injection of autologous ADSVF could reduce the process of fibrosis, improve vibration and then dysphonia and quality of life in patients with scarred vocal folds. In the absence of a reference treatment, the effectiveness of the ADSVF will be compared to a placebo: the local injection of excipients solution. This study will test efficacy of the autologous ADSVF to treat vocal folds scarring. It is a randomized, double-blind, phase II clinical trial conducted according to a 2-treatment parallel design, with medico-surgical and scientific collaboration. Recruitment and follow-up of patients will be done in 4 university hospitals by the respective ENT teams (Marseille, Toulouse, Nice and Montpellier): 36 patients will be recruited and treated on a 24 months period. At inclusion, 36 patients will be randomized (1:1 ratio) into two groups: ADSVF group and placebo group. Adipose tissue removal, ADSVF production and injection of ADSVF or placebo will be done on the same day during a short hospital stay. Patients will be followed and evaluated at 1 and 6 months with self-evaluation (Voice Handicap Index and a 10 points scale), video-laryngo-stroboscopic examination, vocal assessment with perceptive, acoustic and aerodynamic parameters and evaluation of adverse events. At the end of this 6-month follow-up (primary endpoint), patients of each group having tolerated the first injection well but in therapeutic failure (improvement of VHI <18 as described by Jacobson in 1997 or improvement of VHI ≥ 18 but not normal which means > 20 according to Woisard, 2004) will be offered an injection of thawed and washed ADSVF. Patients will continue to be followed in open-label on the same endpoints.
Microsurgical breast reconstruction is most commonly performed with free abdominal flaps, which leave a long transverse lower abdominal scar. Due to tension across the incision, these scars frequently widen and hypertrophy. Hence, modalities that can reduce this tendency, thus, improving scar appearance are desirable. Here, we wish to investigate the impact of the Neodyne embrace device on postoperative abdominal scar appearance. The proposed study is novel in that it is the first RCT investigating the effect of the embrace device on scar appearance in the context of microsurgical breast reconstruction.
The incidence of perineal scars after a pregnancy is high, either related to an episiotomy or to spontaneous perineal tears. These perineal scars can result in acute pain but also in chronic pain for some women. Medical treatment includes level 1 and 2 analgesics and, even for a few women, level 3 analgesic. The MILTA® uses photons which are emitted with low intensity in the visible and near infrared combining 5 physical principles to reduce pain : 1- The NPCL (Nano-Pulsed Cold Laser) emissions in coherent infrared light, at 905 nanometers; 2- Non-coherent emissions, pulsed by trichromatic RGB CSM diodes (400 to 650 nm); 3- Continuous non-coherent infrared emission monochromatic diodes at 905 nm; 4- A constant circular magnetic field (200 millitesla) equivalent to the terrestrial magnetic field and 5- The effect of magnetic tunnel which potentiates the light propagation. MILTA® treatment has been shown to be effective in various managements of pain, but has never been used in pain related to perineal scars. This randomized controlled trial aims at assessing MILTA vs placebo to reduce pain related to perineal scars after pregnancy.
This multicenter prospective randomized controlled trial aims to investigate the ishtmocele rates after c-section delivery depending on using different suture materials for the uterine closure.
This is an observational cohort study which will look at the biomarkers from blood and tissue sample for adult patients with hypertrophic scarring due to burns/trauma incident over 12 months from date of recruitment. The study will assess the kinetics of the response to fractionated carbon dioxide laser therapy in hypertrophic scars.
The scar site was divided into 3 sites; combined IPL/fractional Er:YAG laser treatment site, fractional Er:YAG laser treatment site and untreated control site. At baseline, three lesions were randomized to IPL / fractional Er:YAG laser combination therapy site, fractional Er:YAG laser treatment alone site, and untreated control site. The laser treatment was conducted total three sessions, immediately at suture removal (baseline), 4 weeks after suture removal and 8 weeks after suture removal. The evaluation of scar site was conducted 3 months later after last treatment (20 weeks after suture removal).
Urinary tract infection (UTI) is the most frequently occurring serious bacterial infection in young children and accounts 5 to 14% of emergency department visits Formation of renal scarring in children has been associated with serious complications as hypertension, preeclampsia, and end stage renal failure in young age . So, this study aims to determine whether dexamethasone reduces the renal scarring in children will be treated with antibiotics for acute pyelonephritis. investigators propose to conduct a multi center, randomized, placebo-controlled, double-blind clinical trial, that will evaluate the efficacy of dexamethasone (0.3 mg/kg every 12 hours per day orally for 3 days) in preventing renal scarring in young febrile children (2 months to 14 years) with a first-diagnosed UTI. 120 Participants will be enrolled over a 3-year period from 6 sites.
