Active clinical trials for "Ulcer"

The Study purpose is to evaluate Helicobacter pylori susceptibility to Clarithromycin and to estimate eradication and healing rates of duodenal ulcer routine eradication therapy at the end of treatment and 52 weeks from the therapy start

A prospective, randomized trial to determine indigo carmine dye spraying and narrow band imaging (NBI) of colonic mucosa to detect dysplasia in ulcerative colitis (UC). Confocal laser microscopy may be beneficial in the further assessment of abnormalities identified by these methods.

This study is being done to: To attempt to increase the detection of precancerous colon tissue in patients with chronic ulcerative colitis and primary sclerosing cholangitis; To determine if an investigational scope that can look at the lining of the colon in different ways will help the doctor identify abnormal tissue in patients with chronic ulcerative colitis and concurrent primary sclerosing cholangitis; and To determine if this investigational scope can accurately detect precancerous or cancerous tissue in patients with chronic ulcerative colitis that are known to have had cancerous or precancerous tissue in the past.

This study is designed to test a prototype imaging instrument that relies on Medical HyperSpectral Imaging (MHSI) technology for the assessment and prediction of diabetic foot ulceration and wound healing. The imaging system utilizes the biomarkers of oxyhemoglobin (oxyHb) and deoxyhemoglobin (deoxyHb), in the upper layers of skin on the foot as: a metric for assessing wound healing, a reflection of microvascular disease, and determining tissue at risk for forming new ulcers. MHSI results will also be compare with ABI and TcPO2 measurements.

The investigators plan to do a retrospective chart review on patients who underwent laser treatment for their foot ulcer at the UT Southwestern wound clinic.

Although Crohn's disease and ulcerative colitis are the main subtypes of inflammatory bowel disease, they differ substantially in disease behavior, prognosis, and treatment paradigm. However, making an accurate diagnosis of Crohn's disease versus ulcerative colitis and assessing disease activity beyond the level of mucosal inflammation remain challenging with contemporary modalities. The objective of the study is to determine the novel role of endoscopic ultrasound in A) differentiating Crohn's colitis versus ulcerative colitis and B) monitoring disease activity in these patients.

This is a multicenter study of patients with diabetic foot ulcers (DFU) to develop and validate potential tissue-based biomarkers that predict DFU wound recurrence. Trans-epidermal water loss (TEWL) will be measured on the closed wound site and a location similar to the wound site (reference site). Participants will be enrolled within two weeks after closure of their DFU. Complete wound healing will be verified at a second visit two weeks later and this visit will start the 16 week timeline where participants will be followed weekly by phone until the earliest of DFU wound recurrence or 16 weeks. Participants who experience a DFU wound recurrence and a subset of participants who do not experience a DFU wound recurrence by week 16 will be asked to attend one final visit.

The objective of this study protocol is to use wound biopsies that have been obtained during standard of care management for further scientific evaluation after standard evaluation by a pathologist. Further imaging and molecular analyses would closely evaluate the presence, architecture, and interaction of wound biofilm and human host tissues.

For both induction of remission and in maintenance of remission, different doses and treatment durations are used in practice. The aim of this study is to assess how mesalazine is used in clinical practice, at which doses and for how long and how these differences impact the patient disease state and work productivity.

(i) To compare a new diagnostic PCR with established diagnostic procedures for T. pallidum (serology, dark field microscopy), H. ducreyi (cultivation), HSV types 1 and 2 (cultivation, PCR). (ii) To assess the frequency of infections with T. pallidum, H. ducreyi and HSV types 1 and 2 in patients with genital, anal and oropharyngeal ulcers by a new PCR.
