Treating sleep apnea in adults caused by tonsillar hypertrophy with intracapsular tonsillectomy by coblation

The goal of this clinical trial study: is to determine the effect Botulinum toxin type A iontophoresis in hypertrophic scars for post burned patients. The main question is it aims to answer is: Does Botulinum toxin type A iontophoresis may help in minimizing postburn hypertrophic scars? Participants will receive the treatment for 3 months. Assessment will be done before and after treatment.

The study is being conducted to learn why some patients with Benign Prostatic Hyperplasia (BPH) do not respond to a commonly used treatment drug, Finasteride. The hope is to find ways to predict which patients will not respond to Finasteride so that, in the future, these patients can be identified prior to offering this treatment and they can be offered alternative treatment strategies in its place. The aim is to see if noninvasive techniques such as MRI can detect inflammation of the prostate to assist with early detection of those who will and who will not respond to Finasteride.

Executive Summary Hypertrophic scars are irregular, raised scars that can cause debilitating symptoms including pain, pruritus, and restricted movement in nearby joints. There are also often significant psychosocial elements with these scars that are especially significant in the vulnerable pediatric population and their parents. Current scar treatment modalities are limited. In recent years, the advent of ablative fractional laser (AFL) resurfacing technology has shown great promise but there remains a need to expand high-level evidence and develop optimal laser treatment parameters for patients. In this study, the investigators aim to evaluate the efficacy of ablative fractional CO2 laser treatment of hypertrophic scars in children and define a set of laser treatment parameters to develop a treatment protocol that maximizes the safety and efficacy of AFL therapy in the pediatric population. This will be a prospective split-scar clinical trial at Alberta Children's Hospital. A sample size of 44 scars will be sufficient to detect a clinically significant improvement in total POSAS score, our primary outcome measure. Children (age 1- 17) who present with hypertrophic scarring following an acute injury or burn may be included in the study. All patients will receive standard scar treatment modalities and will be followed by our plastic surgery team and rehabilitation team. Each scar being studied will be split into two halves which will be assigned a unique "Site ID" that will be recorded in a data collection sheet and used to identify scars for assessment. All laser treatments will be performed by a single surgeon using the UltraPulse CO2 Laser (Lumenis, Israel) and will be done at the Alberta Children's Hospital in the main operating room under a general anesthetic. Patients will receive laser treatments at 4 to 8-week intervals for a total of 3 sessions. A combination of the SCAAR FX and Deep FX treatment modes, with or without Active FX treatment mode, will be used according to individual patient and scar characteristics. Data collection includes demographic data and original burn data. Assessment tools including the POSAS and SCAR-Q questionnaires, clinical photographs, and cutometer will be used at various time points to document changes in scar appearance and pathology over the study period. Mean values for the cutometer measurements as well as the POSAS and SCAR-Q questionnaires will be compared between laser-treated and control scar sites. Each of these datasets will be tested for normality using the Shapiro-Wilk test. Non-parametric data will be compared using Wilcoxon signed-rank test and parametric data will be compared using Student's t-tests.

The investigators compare the efficacy of alpha-blocker and 5-ARI withdrawal to continued combination therapy on the maintenance of LUTS and improvement of quality of life outcomes in men with benign prostatic hyperplasia.

Study name: Prospective Comparison of Angiotensin receptor neprilysin inhibitor (ARNI) with Amlodipine on ventricular remodeling in hypertension and left ventricular hypertrophy. Medicine: sacubitril/valsartan (ARNI, 200mg tablet) and the matching placebo; amlodipine (5mg tablet) and the matching placebo. Rationale: according to the results of previous clinical studies, ARNI has obvious advantages in improving cardiac remodeling and reducing blood pressure. However, there is no evidence to demonstrate the efficacy of ARNI in reducing blood pressure and improving ventricular remodeling in hypertension patients with left ventricular hypertrophy (LVH) compared with calcium channel blockers. Objective: to demonstrate the superior efficacy of ARNI on improvement of LVH and blood pressure control compared with amlodipine in hypertension patients with LVH. Study design: This study This is a 24-week prospective, randomized, active-controlled, double-blind, multi-center study, with two equally sized treatment groups: sacubitril/valsartan (200mg tablet); amlodipine (5mg tablet). Study population: men or women aged over 18 years; Untreated patients or patients with taking single antihypertensive drugs; Essential mild to moderate hypertension; Echocardiographic diagnosis of LVH. Randomization and treatment: Eligible patients will be randomly divided into 2 groups, taking one pill of sacubitril/valsartan (200mg tablet) + one pill of matching placebo of amlodipine daily, or one pill of amlodipine (5 mg/tablet) + one pill of matching placebo of sacubitril/valsartan daily. Follow up: after meeting the inclusion criteria, there will be 2-week placebo run-in. Then patients will be randomly assigned into ARNI group and amlodipine group. There will be 5 visiting points in the treatment period, which will be the 4th week, 8th week, 12th week, 18th week and 24th week. Sample size: 120 patients in total. Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in April 2021, recruitment will start. Patients enrollment and follow-up will be performed between June 2021 to June 2022.

The primary purpose of this study is to evaluate the feasibility, the safety and the efficacy of the transapical beating-heart septal myectomy for the treatment of hypertrophic obstructive cardiomyopathy. This is a prospective, single-arm, single-center, first-in-man study.

Open-label, non-randomized, prospective, multi-center, self-controlled clinical study with masked evaluation.

The goal of this clinical trial is to evaluate the safety and effectiveness of human umbilical cord mesenchymal stem cell (hUCMSC) therapy in patients undergoing medium-thickness skin grafts for donor site wounds. The study aims to answer the following main questions: Question 1: Does hUCMSC therapy improve the healing quality and speed of donor site wounds in comparison to standard treatment? Question 2: Does hUCMSC therapy reduce scar formation in the donor site wounds? Participants in this study will undergo medium-thickness skin grafts, and those in the treatment group will receive hUCMSC therapy. The main tasks for participants will involve regular follow-up visits, monitoring of wound healing progress, and assessment of any potential side effects or complications associated with the therapy. In order to evaluate the effectiveness of hUCMSC therapy, researchers will compare the treatment group receiving hUCMSC therapy with a control group that receives standard treatment alone. The aim is to determine if the use of hUCMSC therapy leads to improved healing outcomes and reduced scar formation compared to the standard treatment group.
