Active clinical trials for "Hyperplasia"

Benign prostatic hyperplasia (BPH) is a prevalent entity, affecting over 50% of men older than 60 years.In cases with moderate to severe lower urinary tract symptoms (LUTS) monopolar transurethral resection of the prostate (TUR-P) is the standard treatment. Especially in frail patients, conventional TUR-P is associated with relevant and potentially deleterious complications, e.g. TUR syndrome. Using isotonic saline, like in bipolar TUR-P and transurethral laser vaporization (TUV-P), TUR syndrome can be prevented. The short-term complication rate with the Thulium laser is similar to the rate described after vaporisation with other laser systems18-23 and less than that with TUR-P. Despite recent publications on the safety and complications with Thulium vaporisation of the prostate, to the investigators knowledge, until now, no prospective trial has directly assessed, whether absorption of irrigation fluid occurs and to what extent in Thulium Laser vaporisation of the prostate. The investigators therefore aim to investigate if absorption of irrigation fluid occurs during Thulium Laser vaporisation of the prostate by expired breath ethanol test.

Autologous adipose-derived regenerative cells (ADRC) will be extracted from lipoaspirate by enzymatic digestion from a portion of the fat harvested from the patient's front abdominal wall. Transurethral bladder neck resection followed by the injection of ADRCs suspension will be performed. This is a single arm study with no control. All patients receive cell therapy.

Congenital adrenal hyperplasia (CAH) in its classic neonatal form with severe salt-wasting represents a challenge for pediatric endocrinologists in order to maintain sodium balance, especially as the physiopathology and optimal therapeutic management of this urinary salt loss remain poorly studied, particularly during the neonatal period. The human kidney presents the characteristic of being immature at birth with a functional tubulopathy associating sodium wasting and difficulty to concentrate urine, in connection with a transient renal resistance to aldosterone action, which is exacerbated in case of CAH by insufficiency of aldosterone production. The objective of project is therefore to study the secretion profiles of plasma and urinary steroids in neonates with classical salt-wasting form of CAH before treatment and under treatment with Fludrocortisone and Hydrocortisone during the first months of life, using an advanced technology: LC-MSMS (Liquid chromatography coupled with tandem mass spectrometry). The study of the existence of a correlation between plasma and urinary steroid profiles will also make it possible to subsequently consider simplified medical follow-up for these patients. This project will lead to a better understanding of sodium handling and steroid secretion and excretion profiles in CAH neonates, in order to improve the therapeutic management of mineralocorticoid replacement in these patients.

This cross-sectional study investigates the physical capacity of patients, who have undergone a periacetabular osteotomy for hip dysplasia within the last 1-5 years.

A real world study to evaluate the feasibility, preliminary safety and performance of Rezūm system in BPH treatment in China Rezūm RWS study

Background: Oral epithelial dysplasia (OED) is a condition with an increased risk of oral cancer. Due to the current changes in the factors associated with these diseases (because of human papillomavirus), it is expected that those who have no history of smoking or alcohol, young (<50 years old), and white male would be commonly affected. Those individuals require a higher need for information, preferred a more active role in decision-making, and have a longer lifespan than older individuals. There remain no detailed studies of whether the informational needs delivered to patients with OED met their needs or indeed what information such patient may wish. A few tools are available to evaluate the IN of patients with head and neck disorders. However, the items of these instruments were dedicated to a particular disease (e.g. cancer) and hence are not applicable to be used for OED. Project aims: To evaluate the psychometric properties of the Oral Epithelial Dysplasia Informational Needs Questionnaire (ODIN-Q), developed and revised in the preliminary work for the proposed study, in a cohort of patients with OED. Timescale: 19 months. Clinical significance: This questionnaire can be useful in clinical practice. It could help to meet the patient's information needs and plan educational interventions for those showing unmet needs.

The correlation between the change of serum prostate-specific antigen (PSA) or PSA velocity (PSAV) and severity of lower urinary tract symptoms (LUTS) has been poorly understood. Previous studies usually focused on the treatment efficacy or preventive role of alpha blockers (AB) for clinical progression of benign prostatic hyperplasia (BPH) and AB therapy in real-life practice improved BPH/LUTS and reduced the risk of overall clinical progression. We hypothesized that the change of PSA and PSA velocity would be correlated to LUTS severity in the groups of BPH and prostate cancer.

Adherence and length of treatment with a 5-alpha reductase inhibitor (5ARI) therapy may be associated with improved clinical outcomes for patients with enlarged prostates (EP) and lower health care related costs. The objectives of this study are to quantify 1.) the relationship between 5ARI adherence and length of therapy and the likelihood of acute urinary retention (AUR), prostate-related surgery (emergency and non-emergency), and clinical progression (defined as AUR and/or prostate-related surgery); and 2.) the monthly EP-related, medical costs in a Medicaid and Medicare population. The null hypothesis is that no differences will be observed in the outcomes and costs of patients who adhere to long-term 5ARI therapy and those who do not. The test hypothesis is that patients with higher levels of adherence to 5ARI for a longer period of time will experience significantly fewer adverse outcomes and significantly lower treatment costs. The data source for this analysis is the MarketScan database, which contains medical and pharmacy claims for commercial health plan members and Medicare recipients. Medical and pharmacy claims data are sourced directly from health plans and employers. The database represents approximately 18 to 20 million individuals annually and nearly 22 million Medicaid enrollees from multiple states. The database includes the Medicare-covered portion of payment, the employer-paid portion, and any out-of-pocket expenses paid by the beneficiary. The study design is a retrospective cohort analysis. Each patient's index date was defined as the date of the first fill for a 5ARI prescription.

Background: - Polycystic ovarian syndrome (PCOS) is a group of disorders related to problems with the secretion of certain hormones, which can lead to reproductive and other issues in women. Frequent complications of PCOS include irregular menstruation, development of ovarian cysts, and insulin resistance. The adrenal glands, which sit on top of the kidney, are involved in the production of certain hormones and the regulation of steroid levels in the blood, and may be affected in women with PCOS. Researchers are interested in studying possible connections between the adrenal glands and PCOS in young women who have been diagnosed with PCOS and healthy volunteers with normal menstrual function. Objectives: - To investigate possible connections between adrenal gland steroid hormone secretion and polycystic ovarian syndrome. Eligibility: Women between 16 and 29 years of age who have been diagnosed with PCOS, or who are healthy volunteers with normal menstrual function. Participants must be willing to discontinue the use of oral contraceptives or any other medications that alter steroid hormone production for at least 1 month before the start of the study. Design: Participants will be screened with a physical examination, medical history, and blood and urine tests. All participants will also have a pelvic (ovarian) ultrasound. All participants will be admitted to the hospital for a 1-week testing period, which will involve the following tests: Regular blood draws for two 2-hour periods (late evening and early morning) to measure hormone levels Fasting blood draws with a dose of corticotropin to test the body's adrenal function Hormone level measurement following regular doses of dexamethasone (a drug that controls the function of the adrenal gland) Daily urine collection for 6 days. Other studies, such as imaging studies of the adrenal glands, may be conducted as required by the study researchers.

The specific aim of this proposed pilot study is to compare two standardized processes (paper and electronic) to deliver a customized MedlinePlus health information prescription.
