Active clinical trials for "Dilatation, Pathologic"

The purpose of the present clinical investigation is to collect data regarding the safety and effectiveness of the Aqueduct 100 device. The effectiveness of the Aqueduct 100 will be determined by evaluating the ability to reach desired cervical dilation, and the time frame required to reach desired cervical dilation.

Study to assess the safety and efficacy of the XprESS device for transnasal Eustachian tube dilation.

This study is being done to see which treatment is more effective in improving the difficulty of swallowing. Researchers are comparing self-dilation to endoscopic dilation.

The overall objective of this proposed trial is to examine the vascular protective effects provided by the daily consumption of 39g of freeze dried strawberry powder (FDSP) for four weeks. The study population will be older men (60-80 years of age).

Primary objective: To study the difference in dilation and evacuation (D&E) procedure time following overnight cervical preparation with laminaria or Dilapan-S™. The investigators hypothesize procedure time will be less with Dilapan-S™. Secondary objectives: To compare the use of laminaria and Dilapan-S™ for differences in: (1) initial cervical dilation before D&E; (2) need for mechanical dilation to accomplish D&E and ease of dilation if required; (3) number of osmotic dilators placed; (4) ability to complete the D&E procedure without further cervical preparation; (5) complications; (6) pain and other side effects; (7) patient acceptability; and (8) provider acceptability.

Frozen shoulder or adhesive capsulitis is a common cause of shoulder pain, estimated to affect 25% of the general population. Many forms of treatment have been advocated for frozen shoulder including physiotherapy, injection with steroid, distension arthrogram with steroid, manipulation under anesthetic and arthroscopic releases. There is no general agreement in favour of one form of treatment, and the response to a particular treatment varies in different series. A few randomized controlled trials appear in the literature. Most of these showed improvements with steroid use, but the results were not always statistically significant. One randomized control trial reported superior results in favor of arthrographic joint distension with steroid compared to a saline placebo. To our knowledge there have been no other similar randomized trials to support these results. The objective of this study is to determine if arthrographic distension of the shoulder joint with steriods is an effective treatment modality for adhesive capsulitis as compared to injection with local anesthetic and contrast alone. The study design is a placebo-controlled, double blind clinical trial where participants will undergo distension arthrogram of the shoulder and be randomized to receive either Triamcinalone (steroid), lidocaine and contrast or injection with lidocaine and contrast alone.

Intraventricular hemorrhage and its resultant post-hemorrhagic hydrocephalus are significant risk factors for the development of neurodevelopmental delays in preterm infants. The purpose of this study is to determine 1) the incidence of progressive post-hemorrhagic ventricular dilatation (PHVD) in infants with severe intraventricular hemorrhage (IVH), 2) the effect of ventricular dilatation on brain status (cerebral oxygenation, electrical activity, and biomarkers of cerebral damage and repair), and 3) if using ventricular measurements, derived from cranial ultrasound to guide removal of cerebral-spinal fluid through an Omaya reservoir, will help resolve ventricular dilatation and decrease the need for ventriculo-peritoneal (VP) shunt insertion. The hypothesis of this research project is that, by using ventricular measurements to guide the frequency of CSF removal, the rate of VP shunt insertion will be decreased in preterm infants with severe IVH and PHVD. The investigators further hypothesize that cerebral injury, as measured by cerebrospinal fluid (CSF) concentration of biomarkers of neuronal and glial damage and inflammation, will decrease over time with resolution of PHVD.

WHAT WAS KNOWN *Standard CXL is the common procedure for treating progressive corneal ectasia. Modifications of the standard protocol were introduces to reduce its complications especially long exposure to ultraviolet rays. The Accelerated protocol, while believed to overcome this issue with comparable outcomes, has not been studied fully in patients with ectasia following corneal refractive surgery and penetrating keratoplasty. WHAT THIS PAPER ADDS Accelerated CXL is as safe and effective as the Standard CXL in halting the progression of ectasia post refractive surgery and penetrating keratoplasty with the benefit of: reduced ultraviolet exposure, reduced operation time, and reduced patient discomfort.

Women undergoing mechanical cervical ripening for labor induction will be randomized to Dilapan-S® versus Foley bulb. The investigators hypothesized that osmotic cervical dilators (Dilapan-S®) are as effective as Foley bulb catheter in rates of vaginal delivery.

Prospective, randomized multicenter study to determine the safety and effectiveness of performing corneal collagen cross-linking (CXL) using riboflavin and UVA light in eyes with ectasia after refractive surgery.
