Active clinical trials for "Hyperplasia"

The purpose of this study is to evaluate an imaging capability Prostate Mechanical Imager (PMI), a PC-based device utilizing a transrectal probe with pressure sensor arrays and motion tracking system, aimed at providing composite elasticity images of the prostate.

The purpose of this study is to examine the movement pattern in patients with hip dysplasia preoperative, six and 12 month after minimally invasive approach for Periacetabular osteotomy (PAO). Secondary to examine the movement pattern in patients compared to healthy controls and historical data.

Oral epithelial dysplasia (OED) is one of the common precancerous lesions among Chinese adults. Biomarker is not available for detection of malignant potential of OED till now. p16 is an important tumor suppressor gene, which is inactivated frequently by methylation of CpG island in early stage of carcinogenesis. The present cohort study is to investigate whether p16 methylation is correlated with malignant transformation of OED.

A prospective multicenter trial has been started in Korea to evaluate the diagnostic accuracy of endometrial aspiration biopsy compared with D&C in patients treated with progestin for endometrial hyperplasia (EH). For conservative treatment of EH, oral progestins are most commonly used method with various treatment regimens and more recently, the levonorgestrel-releasing intrauterine system (LNG-IUS) also has been used successfully to treat EH. However, there is no report about the accuracy of endometrial sampling during hormonal treatment for follow-up evaluation of EH. Patients with histologically confirmed EH are offered hormonal treatment, one of the following 3 options: oral medroxyprogesterone acetate(MPA) 10mg/day for 14days per cycle, continuous oral MPA 10mg/day, or insertion of LNG-IUS. Histological surveillance is performed at 3-months or 6-months following initial treatment. Endometrial tissues are obtained via endometrial aspiration biopsy using a pipelle and D&C. In case of using LNG-IUS, endometrial aspiration biopsy will be done with LNG-IUS in uterus and then, after removal of LNG-IUS, D&C will be done. The biopsy findings will be compared. The primary endpoint is the consistency of the results of the endometrial aspiration biopsy and D&C. The secondary endpoint is the response rate with 3 types of progestin treatment at 6 months.

To study Safety and efficacy of Tadalafil vs. Tadalafil with Sildosin in the management of moderately and severely symptomatic patients of prostatic hyperplasia

Pulse diagnosis is one of the traditional diagnostic methods of traditional Chinese medicine, which is of great significance in the process of disease diagnosis.Pulse diagnosis is the diagnosis of disease by touching the pulse of the radial artery at the wrist. Different diseases reflect different pulse characteristics.What we've found in long-term clinical observation is that patients with benign prostatic hyperplasia have something different in their pulse,the abnormal pulse we called "astringent pulse".There is no modern physiologic and pathological description on the occurrence of "astringent pulse" in traditional pulse science, so we study it from acoustics perspective.Our team thinks that every beat of the heart produces a vibration, which produces sound waves，the sound waves travel through the blood and eventually reflect off the arterial walls.When an organ(such as the prostate)，develops hyperplasia, local blood flow changes,the flow of blood, which should be laminar, changes and becomes turbulent，the conduction of sound waves in turbulence is disordered，so we end up with pulse features that are different from normal people that are reflected on the arterial wall. We have previously studied the pulse characteristics of chronic gastritis, coronary heart disease, cirrhosis and some other diseases，different pulse sounds were collected and analyzed using an independently developed Acoustic Pulse Detection System，the ideal results have been obtained.We found that most of the abnormal sound waves were between 20Hz and 500Hz, so we classified this sound wave as low frequency and audible sound wave.Based on the above analysis, this study will use the acoustic pulse detection system to collect the pulse images of patients with benign prostatic hyperplasia(BPH).We expected to collect the pulse waves of 62 patients and 62 relatively healthy people without BPH, and use Fourier transform, wavelet analysis and other analysis methods to study the characteristics of the collected sound waves, and observe the pulse characteristics of BPH disease.Then diagnostic tests were carried out to calculate the sensitivity and specificity of the acoustic pulse detection system in the diagnosis of BPH. This experiment will further verify the effectiveness of pulse diagnosis of diseases, and finally lay a foundation for the development of pulse diagnostic instrument can diagnose a variety of diseases.

A prospective single centre study to evaluate the safety and effectiveness of using contrast enhanced ultrasound and echogenic embolic agent Ekobi Embolization Microspheres in Prostate Artery Embolization for the Treatment of Men with Benign Prostatic Hyperplasia

The efficacy and safety of holmium laser enucleation of the prostate (HoLEP) for the treatment of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) have been comprehensively assessed. However, HoLEP is considered as a challenging procedure with a steep learning curve. As such, HoLEP is not as yet considered the gold standard for the surgical treatment of LUTS/BPH by international clinical guidelines. The investigators aim to assess the complications and outcomes of patients treated with HoLEP by high volume surgeons, in order to provide data on the safety of the procedure and identify the profile of patients who may benefit from a dedicated clinical management to reduce the risk of post-operative complications.

To determine if the prior prolonged use of medication, as a treatment for benign prostatic hyperplasia, reduces the efficacy of Holmium laser enucleation of the prostate (HoLEP) for patients with benign prostatic hyperplasia (BPH).

Congenital adrenal hyperplasia (CAH) is a genetic disorder that affects the amount of steroids that the body forms. The most common form of CAH is 21-hydroxylase deficiency (21OHD), which leads to cortisol deficiency and causes the development of mature masculine characteristics in newborn, prepubescent, and grown females, and prepubescent males. Prenatal treatment with dexamethasone, a corticosteroid, has been shown to reduce the masculinization of genitalia. However, the long-term effects of dexamethasone on the children who received it as fetuses and on mothers who were exposed to it while they were pregnant have not been determined. This study will investigate potential long-term adverse side effects of prenatal dexamethasone treatment in children and young adults who received dexamethasone as fetuses and their mothers who were exposed to it during pregnancy.
