Comparing Vacuum-Assisted Percutaneous Excision to Open Surgical Excision for Borderline or High-Risk...
Breast FibroadenomaAtypical Ductal Hyperplasia8 moreThis randomized controlled trial compares vacuum-assisted percutaneous excision to open standard surgical excision in women who have high-risk or borderline, non-malignant breast lesions with respect to efficacy, safety, cosmesis and patient satisfaction.
Impact of Extended CPAP on Bronchopulmonary Dysplasia
Bronchopulmonary DysplasiaPrematurityThe purpose of this pilot study is to compare if keeping infants on CPAP (continuous positive airway pressure) support for an extended period of time until they are 32 weeks corrected gestational age or 1250 grams (approximately 2 pounds and 12 ounces) will decrease their degree of lung disease as compared to weaning their respiratory support to HFNC (high flow nasal cannula).
Predictors and Prognostic Factors of Myasthenia Gravis Outcome
Myasthenia GravisAutoimmune Diseases of the Nervous System14 moreThis study aims to characterize the clinical features, frequency of different subgroups of MG, and identify predictors of treatment responsiveness among different subgroups of MG. The predictors are including primary outcome (percentage of changes in MG scales at baseline at time of enrollment and after 3 months) and secondary outcome (treatment-related adverse events). Also it aims to determine the frequency of patients with refractory MG. This information will be used to understand the trends and mechanisms of disease relapse, and optimal management strategies.
C2 Esophageal Squamous Epithelium Dysplasia
Esophageal Squamous Epithelium DysplasiaThis study will evaluate the efficacy and safety of C2 CryoBalloonTM Ablation System for the cryoablation of dysplastic squamous tissue in patients with moderate to severe esophageal squamous epithelium dysplasia.
Middle Lobe Only Laser Vaporization or Total Prostate Vaporization of the Prostate, Prospective...
Benign Prostatic HyperplasiaThe investigator aims to prospectively investigate the efficacy and durability of the middle lobe only versus traditional complete photoselective greenlight vaporization of the prostate in patients with prominent middle lobe. The investigator will select patients based on pre-op cystoscopy if patients have a prominent middle lobe to participate in this study. Researches will start to vaporize only the middle lobe then, at the end of this step, The investigator will look at the verumontanum into the prostatic fossa and determine if the patient is having adequate opened prostatic fossa or not. Patients with unsatisfactory opened fossa will have a complete PVP of lateral lobes, while patients with a satisfactory channel will not receive a complete PVP. Primary objectives of the study are to look into pre and post-operative uroflowmetry and post-void residual, International prostate symptoms scores, need of catheterization, and need for secondary interventions over five then ten years. Secondary objectives are to look into erectile and ejaculatory status using the Male Sexual Health Questionnaire (MSHQ) and MSHQ-EjD Short Form for Assessing EjD. Researchers will follow the patients at three months, six months, one year then yearly for five years then an extension to up to 10 years.
Indications for Breast Reduction in the Public Health Care System
Mammary Gland HyperplasiaThe overall purpose of the project is to create a scientific basis for which patients should be offered breast reduction in the public sector. More specifically , the project aims to: To examine the evidence for current national guidelines for breast reduction. The hypothesis is that BMI, breast volume, resection weight, and mental and physical symptoms affect the outcome of breast reconstruction, both in terms of complication risks, patient satisfaction and quality of life . To investigate which patients benefit the most from a breast reduction, in a health economic perspective. The starting point is that resources are limited and the purpose is to maximize the health effects for the patient at as low cost as possible. The hypothesis is that the health benefits, for the individual and society, are different depending on how big the breasts are and how much symptoms a patient has preoperatively. To examine back function and objective problems in women, with both natural and augmented breasts, with different body constitutions and volumes. The hypothesis is that a certain breast volume give rise to different physical symptoms in different women, depending on their other physical factors. To develop preferences for benign breast conditions that are treated in plastic surgery and for complications that the treatment can cause. Preferences are used to calculate QALY (quality-adjusted life years). Knowledge of preferences is essential for an analysis of healthcare needs. To examine women's experiences of how their breast hypertrophy affects them and their expectations of a breast reduction. The hypothesis is that the experience breast hypertrophy affects patients differently, and that expectations on a breast reduction can vary between different individuals.
Phase II Study to Evaluate the Safety and Efficacy of Prostatic Artery Embolization
Prostate CarcinomaBenign Prostatic HyperplasiaThis is a Phase II prospective clinical trial in which patients with prostate carcinoma and obstructive lower urinary tract symptoms electing for radiation therapy will undergo Prostatic Artery Embolization (PAE) prior to treatment. PAE will be administered by Interventional Radiology. Patients will be seen for follow-up at 6 weeks and 12 weeks following PAE after which they will start definitive radiotherapy. After completion of radiotherapy the patient will be seen at 12 weeks
Risk Assessment of Endometrial Hyperplasia and Endometrial Cancer
Endometrial CancerAbnormal uterine bleeding (AUB) represents common diagnostic challenge in everyday gynecological practice. However, abnormal bleeding is a common symptom of many benign diseases and only indicates the presence of EC in 9% of postmenopausal women and 1% to 2% of premenopausal women, suggesting that many women at low risk undergo unnecessary invasive procedures to rule out cancer. The aim of the study is to create a risk-scoring model of endometrial hyperplasia and endometrial cancer.
Longitudinal Follow-up in Women With Endometrial Hyperplasia Without Atypia
FemaleThis study will prospectively enroll a total of 1000 patients (200 per year) simple hyperplasia/complex hyperplasia (SH/CH) without atypia. All subjects will receive education for exercise and weight control and be randomized 1:1 to with or without metformin intervention. At the end of this 3-year project, an interim analysis will be performed. Since long-term follow-up is intended, therefore for the 4th to 6th year a new grant support will be looked for. The long-term occurrence of endometrial cancer (up to15 years) data will be acquired from national cancer registry, which permission is addressed in the informed sent.
Metformin Hydrochloride in Preventing Oral Cancer in Patients With an Oral Premalignant Lesion
ErythroplakiaHyperplasia2 moreThis phase IIa trial studies how well metformin hydrochloride works in preventing oral cancer in patients with an oral premalignant lesion (oral leukoplakia or erythroplakia). Oral premalignant lesions look like red or whitish plaques or lesions in the mouth that do not rub off and can be associated with a higher risk of cancer. Metformin hydrochloride may help prevent oral cancer from forming in patients with an oral premalignant lesion.
