Active clinical trials for "Ulcer"

Patients with a history of idiopathic gastroduodenal ulcer bleeding face an increased risk of recurrent ulcer gastrointestinal bleeding. Our ongoing clinical trial demonstrates a possible reduced risk of recurrent idiopathic gastroduodenal ulcer bleeding with proton pump inhibitor (PPI), yet there is a significant risk of recurrent ulcer bleeding as PPI may increase the risk of small bowel bleeding. Our preliminary data provide strong plausibility that a combination therapy of misoprostol (MISO) with a PPI reduces the recurrent ulcer bleeding as well as clinical gastrointestinal bleeding. The investigators are going to provide the definitive answer to this important clinical question through a randomised trial.

The research will be carried out in an experimental/randomized controlled manner in order to determine the effect of the frequency of repositioning according to body mass index on the development of pressure ulcers in adults. The sample size was determined as 66 people by power analysis. However, considering the losses, the number of patients included in the sample will 30% higher than the calculated value and it was planned to include 86 patients (43 intervention group, 43 control group) in the study. In the first 24 hours of hospitalization, body mass index will be calculated by skinfold thickness measurement, and data will be collected using the "Structured Questionnaire" for patients with no pressure sores, bedridden, high and very high risk according to the Braden Risk Assessment Scale. In calculating the body mass index of bedridden patients, skinfold thickness measurement, measurement of the interface pressure, which is the most important factor in the development of pressure sores, and calf circumference measurement will be performed to determine the decrease in muscle mass. The research will continue with position change applications between 08-24 hours every day of the week. Patients in the intervention group will be given 30 degrees right lateral, supine, and 30 degrees left lateral positions, 1 hour apart, respectively. Patients in the control group will be given 30 degrees right lateral, supine and 30 degrees left lateral positions, respectively, at 2 hour intervals according to the hospital routine practice. In the initial evaluation, the interface pressure will be measured with the Palm Q-Portable Interface Pressure Sensor from the occipital, scapula, sacrum, heels when the patients are in the supine position, and from the pressure points of the acromion, greater thoracantary, and malleolus prominence when they are in the 30 degrees right and 30 degrees left lateral positions. Patients will be evaluated first within the first 24 hours of hospitalization and on day 21 if a pressure ulcer develops or does not develop a pressure sore a second time. If the study is successful, it is expected that pressure ulcers will not develop in patients who are positioned at more frequent intervals.

The main purpose of this study is to assess the efficacy of flexor tenotomy on the prevention of recurrence of toe ulcers in people with diabetes and a history of toe ulceration. Additionally, the investigators aim to assess interphalangeal joints (IPJ) and metatarsophalangeal joint (MTPJ) angles in a weight-bearing and non-weight-bearing position, bare-foot plantar pressure during walking and quality of life before and after the intervention and compare between study groups.

Pressure ulcers represent a major health issue because of their high incidence and their important consequences. There is an important risk of pressure ulcer acquisition for ICU patients with acute organ failure(s). Specific risk factors identified in ICU are immobility, which accentuates the effects of friction and shears, as well as mechanical ventilation and the use of vasopressors. A repositioning schedule is a guideline for pressure ulcer prevention, but repositioning frequency remains unknown. Adaptation of the repositioning schedule to pressure ulcer risk assessment using Braden scale should decrease the emergence of pressure ulcer. This could limit their important consequences for ICU patients which add to their brittle clinical condition (infection, increased length of stay, mortality…).

This pilot study of 12 patients will test the safety and efficacy of applying autologous, adipose-derived stromal cells (ASCs), uncultured, on a Stage III or IV pressure ulcer or diabetic foot ulcers. Patients will undergo a minimal risk liposuction procedure to withdraw 50-100 cc of adipose tissue. The tissue would be processed to extract the stromal layer of cells that contain stem cells. The ASCs would be injected into a fibrin sealant to be applied to the wound. Patients would be followed for 6 weeks to assess wound healing and tolerance of the treatment.

Patient positioning is an essential part of a preventive strategy for neurocritical care patients. The aim of the study will be to determine whether the positioning of the bed is the same or better compared to the positioning of the patient's bed in the presence of pressure ulcer.

This phase II trial studies the effect of atorvastatin in treating patients with ulcerative colitis who have a dominant-negative missense P53 mutation and are at risk of developing large intestinal cancer. Patients with ulcerative colitis are known to have an increased risk of developing large intestinal cancer. Better ways to control ulcerative colitis and more knowledge about how to prevent colon cancer are needed. Atorvastatin is a drug used to lower the amount of cholesterol in the blood and to prevent stroke, heart attack, and angina (chest pain). It blocks an enzyme that helps make cholesterol in the body. It also causes an increase in the breakdown of cholesterol. The information gained from this study may help doctors learn more about atorvastatin as an agent in cancer prevention, and may help to improve public health.

In this study, investigators aim to use fat grafting in patients with previously healed venous ulcers to study its role on increasing skin thickness and reconstructing skin layers which was damaged by venous hypertension and determine its impact on reducing recurrence rates at 1 year

Inflammatory bowel diseases (IBD), which include Crohn's disease (CD) and ulcerative colitis (UC), are chronic immune-related diseases. IBD symptoms frequently overlap with symptoms of functional GI disorders such as irritable bowel syndrome (IBS) and defecatory disorders, and these symptoms are common in patients with active disease, and also in quiescent disease. Underdiagnosis of abnormal anorectal function may result in an inappropriate escalation of IBD therapy. In this study, the investigators aim to evaluate if damage from chronic inflammation in UC results in anorectal damage such as hypersensitive, hyperactive, poorly compliant rectum, and hypotensive sphincter. If this is the case, early aggressive treatment of the disease is needed. Another important point in this study is to find out which of the anorectal symptoms are due to a hypersensitive, hyperactive, and poorly compliant rectum and not due to mucosal inflammation. The diagnosis of abnormal anorectal function via manometry may help to give the appropriate treatment, such as biofeedback or pharmacological treatment such as loperamide or tricyclic anti-depressants. This may avoid escalation or replacing effective IBD therapy unnecessarily.

This prospective pilot study is to enroll patients with clinically-defined infected wounds. Patients enrolled in the study will be followed for 16 weeks for wound closure (Phase A), and will then begin Phase B. 265 clinically diagnosed infected burn or chronic wound patients will be recruited for this study in Phase A. Based on the expectation that 89% of these wounds will heal within 16 weeks of enrollment, 234 of these patients will continue with the study for Phase B.
