Filter by:Primary aldosteronism (PA) is the excessive endogenous production of the mineralocorticoid aldosterone. Although various rare forms of PA exist, the vast majority of cases are accounted by either an aldosterone-producing adenoma (APA) or bilateral adrenal hyperplasia. During the last decades the prevalence of PA has risen, predominantly due to better awareness of disease. Several studies estimated a prevalence of PA up to 17% in an unselected population of hypertensive patients. However, in a population with resistant hypertension the reported prevalence is even higher: 17-23%. This emphasizes the clinical impact of PA on morbidity and mortality due to high blood pressure. Since both hypertension and aldosteronism are independent risk factors for cardiovascular morbidity, the aim of treatment is curation or reduction of both. After an adrenalectomy for APA normalization of biochemical abnormalities is achieved in almost all cases. Nevertheless, curation of hypertension (systolic blood pressure <140 and diastolic blood pressure <90 mmHg) without the need of antihypertensive medication is accomplished in only 35-45% of the cases. In 2008 the Aldosteronoma Resolution Score (ARS) was developed. This score predicts the likelihood of complete resolution of the hypertension in patients with an aldosteronoma and has been validated by other investigator groups. Reduction of hypertension is also an important clinical outcome and is reported in 90-98% of the patients after surgery. In most studies reduction is defined as a certain decrease in blood pressure or antihypertensive medication. However, there is no consensus on the precise definition of reduction in these patients, which leads to incomparable results. The aim of the proposed study is to determine the proportion of patients with clinically relevant reduction of hypertension after adrenalectomy in a large cohort. Furthermore, the investigators aim to determine the characteristics predicting this clinically relevant reduction. Additionally, the investigators evaluate the predictive value of the Aldosteronoma Resolution Score for clinically relevant reduction and aim to develop a scoring system to help clinicians predict the likelihood of reduction of hypertension after adrenalectomy so it can be used for patient counseling.
Comparison between a 1L of polyethylene glycol+ascorbic acid as a split dose and oral sulfate solution bowel preparation for colonoscopy study design: prospective, randomized, parallel, multi-center trial in 3 hospitals in Korea ( Seoul National University hospital, Seoul National University Bundang hospital, Seoul Metropolitan Government-Seoul National University ) patient inclusion criteria - aged 20-75 adults (out-clinic patients) scheduled for colonoscopy for any indication within the normal process of care
Patients scheduled for an endoscopic submucosal dissection(ESD) in the colorectum will be randomized to the use of a traction device(consisting of an endoscopic clip with a loop of dental floss secured in the lesion to be removed, another clip will anchor the loop to adjacent bowel wall) or a standard ESD.
The purpose of this study is to assess whether the use of large screen during colonoscopy will increase adenoma detection rate.
This study will be a prospective analysis conducted by Geneoscopy Inc. to evaluate the Colosense test, which is a multi-target stool RNA test for colorectal screening.
COLO-DETECT is a clinical trial to evaluate whether an Artificial Intelligence device ("GI Genius", manufactured by Medtronic) can identify more polyps (pre-cancerous growths of the bowel lining) during colonoscopy (large bowel camera test) than during colonoscopy without it.
PURPOSE OF PROTOCOL Objective: To evaluate if the speedometer based on the real-time image analysis can help endoscopists increase their withdrawal time, which is defined as time spent examining the colon during withdrawal of the colonoscope, during colonoscopy. Hypothesis: The trial hypothesis is that use of the speedometer during colonoscopy will increase the average withdrawal time, which is defined as time spent examining the colon during withdrawal of the colonoscope, by 1.6 minutes, possibly increasing the performance of the participating endoscopists. Our objective is to clarify the clinical benefits of this digital tool in colonoscopy. Endpoint: Withdrawal time difference between colonoscopies done without the speedometer (control period) and colonoscopies done with the speedometer (intervention period).
The study is intended to compare the detection rate obtained by performing G-EYE® high definition colonoscopy vs. the detection rate obtained by performing ECV high definition colonoscopy.
This study focused on the key nodes, molecular events and regulatory mechanisms of intestinal microecological disorders that affect the malignant transformation of intestinal epithelial cells into tumors during the occurrence and development of colorectal cancer.
In this single-centre, cross-sectional case series, the investigators aim to evaluate the incidence of facial nerve injury in patients undergoing superficial parotidectomy in the absence of nerve conductor. Data to be collected retrospectively from a prospectively maintained database of consecutive patients, at the Department of Surgery, Liaquat University of Medical and Health Sciences Jamshoro, Pakistan. The sample size was calculated as 101.
