Active clinical trials for "Hyperplasia"

The most common two subtypes of primary aldosteronism (PA ) are aldosterone producing adenoma (APA) and bilateral idiopathic hyperaldosteronism (IHA). Mineralocorticoid receptor (MR) antagonists is the main treatment for bilateral IHA, because of its side effects, the treatment compliance of those patients is poor. Hence, an alternative therapy is needed in such cases. We hypothesized that superselective adrenal artery embolization (SAAE) could be a suitable alternative approach. To our knowledge, SAAE has so far not been applied to treat bilateral IHA. This study aimed to evaluate the efficacy and safety of SAAE in the treatment of PA patients with bilateral IHA.

This phase II trial studies the effect of megestrol acetate alone or in combination with metformin in preventing the progression of uterine pre-cancer (endometrial intraepithelial neoplasia) to endometrial cancer. Megestrol acetate is a drug used to block estrogen and suppress the effects of estrogen and androgens. It is the current non-surgical treatment of endometrial intraepithelial neoplasia. Metformin is a drug that has been found to have anti-cancer properties. Giving metformin and megestrol acetate together may decrease the growth of endometrial intraepithelial neoplasia in the uterus better than megestrol alone.

Barrett's esophagus is a complication of chronic gastroesophageal reflux disease that occurs in up to 10% to 15% of patients with this pathology. Well-defined risk factors have been established and are important because they are considered a precancerous lesion (intestinal metaplasia). The conventional diagnostic methods are ineffective in reliably detecting potentially treatable lesions. Investigators propose the use of vital chromoendoscopy with acetic acid using the simplified classification of Portsmouth looking for areas with loss of acetowhitening and taking targeted biopsies to increase the detection of esophageal neoplastic lesions.

The purpose of this study is to learn the best approach to treating patients with known or suspected Barrett's esophagus by comparing endoscopic surveillance to endoscopic eradication therapy. To diagnose and manage Barrett's esophagus and low-grade dysplasia, doctors commonly use procedures called endoscopic surveillance and endoscopic eradication therapy. Endoscopic surveillance is a type of procedure where a physician will run a tube with a light and a camera on the end of it down the patients throat and remove a small piece of tissue. The piece of tissue, called a biopsy, is about the size of the tip of a ball-point pen and is checked for abnormal cells and cancer cells. Endoscopic eradication therapy is a kind of surgery which is performed to destroy the precancerous cells at the bottom of the esophagus, so that healthy cells can grow in their place. It involves procedures to either remove precancerous tissue or burn it. These procedures can have side effects, so it is not certain whether risking those side effects is worth the benefit people get from the treatments. While both of these procedures are widely accepted approaches to managing the condition, there is not enough research to show if one is better than the other. Barrett's esophagus and low-grade dysplasia does not always worsen to high-grade dysplasia and/or cancer. In fact, it usually does not. So, if a patient's dysplasia is not worsening, doctors would rather not put patients at risk unnecessarily. On the other hand, endoscopic eradication therapy could possibly prevent the worsening of low-grade dysplasia into high-grade dysplasia or cancer (esophageal adenocarcinoma) in some patients. Researchers believe that the results of this study will help doctors choose the safest and most effective procedure for their patients with Barrett's esophagus and low-grade dysplasia. This is a multicenter study involving several academic, community and private hospitals around the United States. Up to 530 participants will be randomized. This study will also include a prospective observational cohort study of up to 150 Barrett's esophagus and low grade dysplasia patients who decline randomization in the randomized control trial but undergo endoscopic surveillance (Cohort 1) or endoscopic eradication therapy (Cohort 2), and are willing to provide longitudinal observational data.

The study will assess the performance of the combined system, i.e., the use of the EsoGuard assay (lab developed test) on cells collected using the EsoCheck (501k cleared device) to detect Barrett's Esophagus (BE), with or without dysplasia, and esophageal adenocarcinoma (EAC) as compared to Esophagogastroduodenoscopy (EGD) plus biopsies in both confirmed cases of BE/EAC and in controls (subjects without a prior diagnosis but undergoing screening for BE/EAC)

The aim of the study is to compare sleep efficiency by means of actigraphy in patients with hypohidrotic ectodermal dysplasia with healthy controls. Sleep efficiency, assessed on actigraphy, sleep architecture assessed on on polysomnography, body temperature and urine melatonin levels will be compared between the patients with hypohidrotic ectodermal dysplasia with healthy controls.

This phase III study is an open-label extension study to be conducted at approximately 36 investigational sites across 3 countries. The study will evaluate the long-term safety and tolerability of Chronocort in participants aged 16 years and over when used as treatment for Congenital Adrenal Hyperplasia (CAH).

Background: Children with congenital adrenal hyperplasia (CAH) can survive well into adulthood with proper treatment. But the change from pediatric to adult care can be challenging. Many people with CAH need extra support as they learn to take control of their own health care needs. Researchers have studied how people respond to different types of patient education. Now researchers want to find out if virtual education, via computer, is a good way to teach people how to manage CAH as they become adults. Objective: To test a virtual method of delivering patient education to adolescents and young adults with CAH. Eligibility: Adolescents and young adults aged 16 to 22 years who have CAH. They must already be enrolled in Natural History Study Protocol 06-CH-0011. Design: Participants may take part in the study remotely; they may also come to the clinic. They will have 3 visits in 1 year. Participants will complete questionnaires. Topics will include what they know about CAH; whether they remember to take their medications on their own; and whether they schedule their own appointments. They will be asked about their quality of life. They will be asked about their physical and emotional health. All participants will be taught how to care for themselves. The participants will be divided into 2 groups. Some will watch an 11-minute video on CAH that focuses on their goals as they become adults. The others will receive standard education. After 6 months, participants will receive CAH education again. After 12 months, participants will repeat the questionnaires from their first visit.

This study evaluates the long term safety and efficacy of use of the Butterfly Medical's prostatic retraction device in Benign Prostatic Hyperplasia (BPH) Patients. The study follows patients implanted with the Butterfly device for up to 5 year after implantation. The evaluations include recording of safety events and BPH related symptoms by Uroflowmetry tests, residual urine and International Prostate Symptom Score (IPSS) questionnaires. The study also assesses the sexual quality of life after implantation of the Butterfly device.

It has been demonstrated that sexual activity was common in the majority of men over 50 years old and was an important component of overall quality of life (QoL). Ejaculatory dysfunction (EjD) is the most common side effect of surgical treatment of benign prostatic obstruction (BPO). It has been considered for decades to be an inevitable consequence of restoring micturition comfort. EjD can have a substantial deleterious effect on the QoL of men with previously maintained regular sexual activity, inducing decreased orgasmic intensity and increased levels of anxiety and depression. A better understanding of the physiology of ejaculation has enabled the emergence of modified surgical techniques that aim to preserve antegrade ejaculation. Our hypothesis is that conservation of ejaculation can be achieved by modified surgical procedures without compromising functional outcomes.
