Filter by:Acne vulgaris, a disease of the pilosebaceous unit, is estimated to afflict 9.4% of the global population, making it the eighth most prevalent and third most significant disease according to the global burden of disease. Post-acne atrophic scars may develop in 95% of acne patients due to aberrant wound healing that affects the pilosebaceous unit and surrounding tissue. Scars are cosmetically unattractive, contributing to the severe psychosocial discomfort observed in acne vulgaris patients. Several approaches exist for the treatment of post-acne atrophic scars, depending on various factors such as the individual's condition, the types of scars present, and the associated expenses. However, treating atrophic acne scars remains challenging for physicians because there is no gold-standard treatment. Thus, combinations of interventions are typically necessary. Fractional CO2 laser and subcision are therapeutic methods proven to be effective in treating post-acne atrophic scars. By creating hundreds of thousands of micro-heat treatment zones (MTZs), fractional CO2 lasers emitting small focal spots (50-80 m) via high-focusing mirrors can efficiently treat acne scars. These thermal damage columns accelerate the healing process of collagen synthesis. Subcision, which can be safely paired with other operations, should be the initial step in treating acne scars since it separates scars from underlying structures. Although several studies proposed that the combination of fractional CO2 laser and subcision was more efficacious than a single therapeutic modality, no study has to date compared the efficacy and safety of simultaneous versus sequential combination of these two methods in the treatment of post-acne atrophic scars. There is a critical need for basic research on the effectiveness and adverse events of combining modalities sequentially as compared to simultaneously due to the high expense of traveling and the downtime needed to recover after each treatment, especially for diseases requiring long-term and periodic intervention such as post-acne atrophic scars. Wound healing is a dynamic process with four distinct but overlapping phases: hemostasis, inflammation, proliferation, and remodeling. The proliferation phase, during which new tissue is formed by a matrix of collagen, elastin, glycosaminoglycans, and other fibrous proteins, begins about four to twenty-one days following an injury. If sequential modalities interfere with each other's proliferative processes, therapeutic efficacy may be compromised. Therefore, our working hypothesis that simultaneous combination is more effective than sequential combination is based on the fact that if the wound-healing process is interrupted, it may stop or progress inadequately. In addition, the investigators anticipate no significant difference between these methods in terms of adverse events frequency and severity, but the downtime in the sequential combination group might be greater than that of the simultaneous combination group. The investigators propose to test the hypothesis by addressing the following two specific aims: Aim 1: to compare the efficacy and patient satisfaction of simultaneous versus sequential treatment using fractional CO2 laser plus subcision. Aim 2: To compare adverse reactions of simultaneous and sequential treatment using fractional CO2 laser plus subcision. Upon completion of this study, the investigators will have (a) compared the treatment outcome of simultaneously versus sequentially combined fractional CO2 laser plus subcision based on ECCA clinical grading score, patient satisfaction, and skin thickness via high-frequency ultrasonography; and (b) compared the incidence and duration of adverse events in simultaneous versus sequential treatment. Optimizing the combination of different interventions will contribute to more efficacious and economical treatment protocols for post-acne atrophic scars.
The 1064-nm Nd:YAG picosecond lasers using fractional micro-lens array (P-MLA) was a promising therapy for skin resurfacing. However, no studies have compared P-MLA with ablative fractional 2940-nm Er:YAG lasers (AF-Er) in treating atrophic acne scars. To evaluate the efficacy and safety of P-MLA and AF-Er for the treatment of atrophic acne scars, we performed a prospective, randomized, split-face, controlled trial. Thirty-one Asian patients underwent four consecutive sessions of randomized split-face treatment with P-MLA and AF-Fr at 4-week intervals.
Traditionally, tools that use unstable surfaces have been used to increase the difficulty of exercises by stimulating the recruitment of a greater number of motor units. A new method is suspension training. It uses the weight of the body and the principles of moments of forces to improve the recruitment of motor units. The difficulty that stimulates this recruitment depends on the amount of instability caused by the suspension apparatus and the position of the body. So this type of training in the elderly can be very interesting due to the ease of adaptation, since it can be used as a facilitating method or to increase the difficulty. It seems that suspension training can have positive effects that will have a direct impact on the quality of life of the elderly, due to improvements in different aspects such as gaining strength and improving balance, consequently reducing the risk of falling. . It is a good alternative to gain strength and improve functional mobility and upper trunk strength in the elderly, to other exercises such as elastic bands, since they produce similar effects. For all these reasons, the program tries to demonstrate that suspension training can be an effective tool to improve the quality of life and reduce the risk of falls in the elderly.
Objective: The aim of this study is to investigate the effect of motor imagery on muscle activity, pain, and function in arthroscopic rotator cuff repair. Methods: As a result of the power analysis (G-Power), 36 participants are planned to be included in this study Block randomization will be used to divide participants into 2 groups, each with at least 18 participants: Group 1 (MI group) and Group 2 (Control group) (Randomizer.org). Both groups will receive a 4-week physical therapy program. MI (Motor Imagination) group will receive a motor imagination program in addition to the physical therapy program. Data will collect using the visual analog scale (VAS), goniometric measurement, circumference measurement, Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH), Kinesthetic and Visual Imagery Questionnaire- KVIQ-20, Tampa Kinesiophobia Scale, 3-question satisfaction questionnaire, superficial Electromyography (EMG) (BTS Bioengineering Free EMG 100 RT). Practice Implications: The current study will contribute to understanding how motor imagination affects muscle activity and muscle atrophy.
The goal of this clinical trial is to assess efficacy and safety in patients with myopic chorioretinal atrophy. The main question it aims to answer are: • Percentage of changes in the chorioretinal atrophic area Participants will be implanted one sheet of PAL-222 into the subretinal space through pars plana vitrectomy. Researchers will compare non-therapeutic eye to see if the changes is significant different.
An open-label, multicentric, non-randomized, single-arm, pilot, interventional clinical investigation to confirm the tolerability and performance of the medical device Halova in lubrication of the vagina and vaginal atrophy treatment.
Spinal muscular atrophy (SMA) is a genetic disease of the nervous system that affects about 1 in 7,0001.2 births and results in very high mortality for patients with the disease. There are about 120 new cases in France each year and an estimated total of 2500 patients. It is the leading cause of genetic mortality in children in France. Until 2017, no etiological treatment was available. Currently, three treatments have been approved and have authorizations in France. The current clinical developments in SMA show the importance of an early treatment for patients. 3. The identification of pre-symptomatic patients is therefore essential to improve the effectiveness of treatments on an individual level and to avoid any loss of chance, as well as to reduce the societal cost of disability for patients treated in post-symptomatic. Several countries in Europe and around the world have implemented regional pilot screening programs for the disease. The screening test is based on a molecular genetic analysis that has been performed for many years, and which is highly reliable; there is currently no biochemical marker that can be used. The objective of our project is to demonstrate the feasibility of neonatal screening for spinal amyotrophy in two French regions before being able to propose to extend it to the whole of France. The management of all screened patients will be decided outside the pilot study, by the existing national multidisciplinary consultation meeting, according to the best available standards of care and will be based on the national network of neuromuscular disease reference centers The objective of the project is not the evaluation of the efficacy of treatments or neonatal screening: these objectives are being studied by existing or otherwise ongoing studies around the world. This project has been set up to be in line with the existing structures in France that are responsible for neonatal screening (via the regional neonatal screening centers (CRDN) and the regional perinatal networks) and for the management of rare diseases (via the neuromuscular disease reference centers and their FILNEMUS network). This project is performed in collaboration with AFM Telethon, Directorate of Health Care Supply, Regional Health Agency (ARS), FILNEMUS network, Novartis Gene Therapies, Roche Pharma AG,Biogen. Investigator wish, as far as possible, to bring this study closer to real life and to be able to generate as much information as possible that can be used directly to prefigure the potential generalization of this screening strategy to the entire national territory.
Nusinersen (Spinraza, Biogen Inc, Boston, MA), the first treatment approved by FDA and EMA for all Spinal Muscular Atrophy (SMA) subtypes, is an antisense oligonucleotide that is administered intrathecally through a lumbar puncture. This procedure can be challenging in some adults with intermediate and late onset SMA (types II-IV) frequently presenting scoliosis secondary to neuromuscular weakness and often treated with spinal instrumentation to prevent worsening deformities. In such patients, in order to access the intrathecal space, US guidance and/or assistance have been recently proposed as useful and successful tool. The US guidance and/or assistance have been associated to a high success rate, a reduction of number of attempts and needle passes to obtain a successful anesthesia. A reduced risk of adverse events (AEs), such as post dural puncture headache (PDPH) and low back pain (LBP), and low patient satisfaction often associated with multiple needle punctures was also reported. Aim of this retrospective study was to report the efficacy, evaluated as rate of the successful procedures and subsequent delivery of nusinersen within the subarachnoid space, the number of attempts, the procedure time and the adverse events (AEs) of interlaminar intrathecal nusinersen administration using either ultrasound assistance or the landmark-based technique in a historical cohort of 51 adult SMA patients.
Tooth extraction is followed by marked alterations of the tissue volume. The resorption process of at least the surrounding mucosa can be altered by using immediate implant placement and additional features such as immediate provisional crown, platform switching and grafting the gap between implant and buccal bone plate. The support of the gingival margin with a provisional crown led to an increase of buccal gingival tissue. Teeth scheduled for extraction will be used to study the effect of a customized healing abutment. The following groups will be randomly assigned: Control: A commercially available healing abutment will be screwed on top of the implant and a collagen sponge will be used to protect the graft. Test: A customized PEEK abutment mimicking the subgingival emergence of the extracted tooth will be screw retained on top of the implant to seal the extraction site.
