Active clinical trials for "Dilatation, Pathologic"

The purpose of this study is the investigation of biomechanical properties of the cornea using computer-aided data analysis. Currently, it is known that keratoconus and glaucoma are ocular disease that are associated with biomechanical alterations of the cornea. Corneal ectasia, especially keratoconus, is a corneal disease that leads to an irreversible loss of visual acuity while the cornea becomes steeper, thinner and irregular. For these patients, surgical intervention (e.g. corneal cross-linking) is performed, in case of disease progression. In glaucoma, the information about corneal alterations serves in two ways, first, correct measurement of intra ocular pressure (IOP); second, early diagnosis of suspects before visual field defects are detectable. Especially, the Corvis ST is an air-puff tonometer that measures intraocular pressure, corneal thickness (CCT) as well as dynamic corneal response (DCR) parameters. Most of the DCR parameters are affected by IOP and CCT: Therefore, algorithm are needed to determine parameters without impact of IOP and CCT that are describe the biomechanical properties of the cornea.

In this study, our primary goal is to compare whether there is any difference in the complication of using pro-seal laryngeal mask or intubation tube in bronchoscopy-guided percutaneous dilation tracheostomy procedure. Our secondary goal is to compare in terms of processing time.

This is a pilot study to test the accuracy and comfort of self-directed ultrasound imaging of cervical dilation and effacement in pregnant women undergoing induction of labor. The study will assess correlation of cervical measurements between self-directed imaging and experienced provider digital cervical examinations.

The purpose of this study is to evaluate the efficacy of Losartan versus Atenolol in the progression of aortic dilatation in patients with Marfan syndrome.

This study is designed to provide information on feasibility and reproducibility of barostat assessments of colorectal sensory functions and compliance and their pharmacological modulation

This is a prospective, single-arm, open-label, multi-center, observational study to assess the acute safety and efficacy of MINI TREK RX 1.20 mm, for descriptive purposes only.

This study is being performed to evaluate the efficacy of ultraviolet-A (UVA)-induced cross-linking of corneal collagen (CXL) in strengthening and optimizing the biomechanical and biochemical stability of the cornea in patients with fruste keratoconus (FFKC), corneas that are suspicious for FFKC and corneas thought to be at higher risk of developing ectasia that will be undergoing laser vision correction.

Background: Abdominal pain, distension, and discomfort are the most frequently seen side effects after colonoscopy. These side effects can cause physical and mental results and increased workloads and care costs. Additionally, the satisfaction of the patients with the colonoscopy process may affect their willingness to undergo repeated colonoscopies in the future which may be required for the surveillance of colon malignity. Currently, there are no studies evaluating the effects of abdominal massage on post colonoscopy these abdominal symptoms. The aim of this study was to evaluate the effect of post colonoscopy abdominal massage on abdominal pain, distension, discomfort, and patient satisfaction. Methods: This study was designed as a prospective randomized controlled study. Participants meeting inclusion criteria will be assigned to intervention and control groups using a random number generator. Participants assigned to the intervention group will receive abdominal massages twice a day after colonoscopy, and participants assigned to the control group will receive only "routine care". The abdominal pain, distension, discomfort, and satisfaction levels of the patients will be evaluated using the Visual Analogue Scale. Conclusions: New approaches are needed to improve the physiological and psychological health levels of patients after colonoscopy and help them return to their daily life activities and social lives faster. The trial will provide valuable evidence to inform clinical application and help evaluate the effects of the use of the relevant intervention.

Comparison Between Meperidine and Drotaverine Regarding the Effect on the Duration of the First Stage of Labor in Full Term Primigravidae

A database analysis and review of histological slides (retrospective) and a patient questionnaire analysis (prospective) will be conducted in Bern (Switzerland) to evaluate the efficacy and safety of esophageal dilation and its effect on the underlying eosinophilic inflammation in patients with Eosinophilic Esophagitis. This trial is investigator driven.
