Active clinical trials for "Hyperplasia"

If intimal growth is such that the initial lumen is narrowed significantly, distal blood flow is restricted and chronic tissue ischemia results. This occurs in native coronary arteries and during restenosis after coronary angioplasty or failure of some coronary vein grafts. Stent implantation has become the principal revascularization technique for coronary artery disease. But, in-stent restenosis (ISR) by neointimal hyperplasia persists as a significant limitation of this procedure in the era of drug eluting stent (DES). Coronary intervention might induce an inflammatory response by arterial wall damage, release of inflammatory and chemoattractant factors resulting in leukocyte and platelet activation. Then, Migration and proliferation of neointimal smooth muscle cells together with the deposition of extracellular matrix might lead to the development of ISR. It is known that matrix metalloproteinases (MMPs) play a key role in the pathogenesis of restenosis by controlling extracellular matrix degradation and the release of matrix-degrading MMPs, including MMP -2 and MMP-9, which facilitate intimal remodeling after angioplasty. Previous studies showed that increased levels of MMPs in coronary arteries undergoing percutaneous intervention may be associated with vascular remodeling and restenosis by promoting migration of vascular smooth muscle cells. Recently, Gregory et al. demonstrated that elevated serum activities of MMP-2 and -9 are associated with dramatically increased restenosis rates after PCI with implantation of DES. In patients with DESs, determination of MMP levels might be useful for identification of patients who are at high risk for ISR. However, not much is known about the relationship between MMPs and neointimal hyperplasia in patients with DES. In this study, the serum activity of MMP-2 and 9 were investigated in patients who had undergone follow-up coronary angiography with intravascular ultrasound (IVUS), which performed at 9 months post-DES implantation. Our aim was to evaluate if individual or combined levels of MMPs were associated with increased neointimal hyperplasia volume, that is, to evaluate the relationship, correlation between the levels of MMPs and neointimal hyperplasia volume.

This research is being done to better understand and test if the investigators can minimize narcotic medication for controlling pain after thyroid or parathyroid surgery. This research will be performed at Doctors Hospital At Renaissance in the investigators clinic and the perioperative area. Participants will be randomly chosen to receive one of two options for pain management that the investigators are already using in the care of patients after surgery. One option includes a narcotic medication and one option includes a non-narcotic and a narcotic as needed. Participants will be asked to complete a form about the level of pain and how much pain medication was needed after surgery in the hospital and while at home. Participants will not have to do any additional visits to participate in this study. The investigators will obtain the research materials at the same time as the usual care visits around the participants' surgery.

Aim: Assess accuracy of histological diagnosis using ultrasound guided biopsy for women with suspected endometrial cancer (as an alternative to hysteroscopy guided biopsy). All women presenting to clinic with suspected endometrial cancer will have an internal ultrasound. If the endometrial lining is thickened an endometrial biopsy will be performed. This can sometimes be done in an outpatient clinic, or sometimes a hysteroscopy and biopsy is needed (on a different day). Hysteroscopy guided biopsy has the advantage of enabling the clinician to perform directed biopsies under vision. Ultrasound guided biopsy is a ubiquitous procedure when used elsewhere in the body however it is not routinely used in this context. It does have the advantage of being easily performed on the same day as the first consultation. In this pilot study we will assess the diagnostic ability and tolerability of ultrasound guided biopsy of women with suspected cancer, as an alternative to hysteroscopy guided biopsy.

To evaluate the improvement in symptoms of Benign Prostatic Hyperplasia (BPH) according to the Prostate Symptom Score (IPSS) and Quality- of- Life (QoL) index after add- on therapy of Umooze twice daily administration for 56 days in patients with BPH.

This retrospective cohort study will assess the association of benign prostatic hyperplasia (BPH) treatment (5-alpha reductase inhibitors (5ARI) and alpha-blocker medications) with the occurrence of prostate cancer related mortality. This study will also assess a number of secondary endpoints including prostate cancer mortality or metastatic prostate cancer, and all cause mortality.

Introduction: The lack of congruence between the acetabulum and femoral head in hip dysplasia compromise the passive stability of the hip joint resulting in increased stress on the acetabular labrum, joint capsule and the muscles acting close to the hip joint. Soft tissue injury is present in hip dysplasia, and pathology of the iliopsoas muscle has been found in 18-50%. To our knowledge, no studies have systematically examined the prevalence of soft tissue pathology in hip dysplasia. The overall aim of this research project is to examine soft tissue pathology in 100 patients with hip dysplasia prior to and one year after Periacetabular osteotomy (PAO). Methods: Soft tissue pathology will be examined in a prospective cohort study on 100 patients with hip dysplasia prior to and one year after surgery. Pathology will be examined using ultrasonography and the Clinical Entities Approach that focus on pathology of the iliopsoas, adductors, rectus abdominis, gluteus medius and hamstrings. Furthermore, hip muscle strength is tested with a dynamometer, hip related health is measured with the Copenhagen Hip and Groin Outcome Score (HAGOS) and physical activity is measured with triaxial accelerometers during a period of 7 days. Perspective: Is it possible to demonstrate pathology of the hip muscles and tendons applying clinical tests, muscle strength tests, and ultrasonography, as it has been found in sports-active people with groin pain, it will make sense to plan and test a specific training program focusing on the pathological soft tissue pathology.

Study to assess efficacy, tolerability and safety parameters of a three month ALNA®OCAS® -treatment with special respect to nocturia

The primary purpose of the study is to evaluate, in obese and hypogonadal patients eligible for bariatric surgery, the effect of testosterone replacement therapy in improving lower urinary tract symptoms (LUTS) assessed using the IPSS (International Prostate Symptom Score) questionnaire, compared to hypogonadal untreated subjects and eugonadal subjects.

The objective of the observational study were to investigate the switch from phytotherapy to ALNA® after at least 4 weeks of phytotherapy and still presented with a symptom sum score of ≥ 8 points (International Prostate Symptom Score (IPSS))

The purpose of this study is to gain information on the safety, efficacy, and quality of life in subjects who have had the GreenLight XPS procedure.
