Filter by:Chronic anal fissure is a linear tear in the distal anal canal. Most chronic fissures require intervention to heal. Surgical sphincterotomy is currently performed. However, the procedure permanently weakens the internal sphincter and may be associated with permanent complications such as incontinence. Current topical treatment or " chemical sphincterotomy" is effective in the short term for about 70% of the patient more than 50% of them will suffer from recurrence. Number of studies support the hypothesis that local ischemia is the reason for failure to heal in anal fissure. Treatment of refractory wounds by macrophage suspension is an innovative method since 1995, macrophage suspensions have been used successfully in more than 1400 patients in several hospitals in Israel without any side effect.Macrophages have key function in almost every stage of wound healing. They help in the digestion of bacteria, in a later stage, they secret IL-6, which influences endothelial cell proliferation and the initiation of angiogenesis. The study hypothesis is that local injection of activated human macrophages into chronic anal fissure may induce fissure healing.
Hospitalization is a traumatic event for the patient and his family at any age nevertheless in the older age. One of its consequences is the difficulty to resume previous activity of daily living especially in older (over 75 years) patients. Sub acute completes the acute phase of the hospitalization and its main purpose is to improve the patient's functional status and quality of life. There are not enough clinical trails to proof this assumption. The purpose of our study is to compare the outcome of acute and sub-acute hospitalization programs by a randomized controlled prospective intervention study. Outcome measures will comprise activity of daily living, functional status, re-hospitalization and utilization of medical services following the hospitalization.Study hypothesis is that sub-acute hospitalization will improve outcomes and will cost less.
A Prospective Double Blind RCT: Controlled Release Oxycodone 10 mg On a 12 h Dosing Schedule Started With The Premedication ,Placebo Controlled Study,On Post Operative Analgesia Management in Laparoscopic Cholecystectomy and Laparoscopic Bilateral Inguinal Hernia (BIH). CRO is indicated for the management of moderate to severe pain when a continuous,around the clock analgesic is needed for an extended period of time.Its safety and efficacy in the first 12-24 hours post operative has not been established.
(i) Main Research Question(s): What is the effect of fondaparinux on coronary graft patency, heart attack, stroke, and death in patients who have undergone coronary artery bypass grafting (CABG)? To reliably answer this question requires a large randomised trial. We propose a pilot study to demonstrate the feasibility of recruiting patients into this study and of performing CT angiograms to measure graft patency at 30 days. (ii) Why is this research important? Coronary artery bypass surgery has made a very important contribution to improving the health and survival of patients with advanced coronary artery disease but still has many problems. One in 10 patients experiences a heart attack at the time of surgery, 1 in 20 experiences a heart attack, stroke, or death during hospitalization, and 1 in 4 patients has at least 1 blocked graft within 1 year of surgery. Fondaparinux, a relatively new anticoagulant drug, has been shown to significantly reduce cardiovascular events and death in patients who have suffered a recent heart attack. Compared to established anticoagulant therapies for acute myocardial infarction, fondaparinux has been shown to be more effective with similar or lower risks of bleeding. Fondaparinux, unlike the most commonly used anticoagulants, does not cause Heparin Induced Thrombocytopenia (HIT), a rare condition with extremely high morbidity and mortality. This drug has never been studied in CABG patients. Our pilot study will provide key information about feasibility that will help us to design and perform a large definitive study in the future. (iii) What is being studied? We will be looking at blood flow in bypass grafts, heart attack, stroke, venous thromboembolism and death. For safety we will be looking at bleeding, transfusion, and need for further surgery because of bleeding. We will also perform laboratory tests for HIT antibodies as their levels are prognostic for the development of HIT and are also related to morbidity and mortality. The incidence of actual HIT cases will also be recorded.
Study objective is to provide prospective randomized controlled data on pediatric pain levels found in PlasmaKnife tonsillectomy and monopolar tonsillectomy.
Skill acquisition refers to the process of improvement of performance following practice experience. This process is the basis for generation of a long-lasting memory. Individuals with Attention Deficit Hyperactivity Disorder (ADHD) have been shown to be impaired on some performance aspects of previously learned skills, an impairment that is often ameliorated, at least temporarily, by psychostimulant medication (the standard therapy in ADHD). The proposed study aims to define the course of learning and of generation of long-term memory consolidation in individuals with ADHD, and to essay the effectiveness of psychostimulant medication on both the learning and retention of the skills.
In this randomized trial surgical therapy and surveillance of ureteropelvic junction obstruction will be compared, regarding partial renal function.
Hypothesis (H0): Labor duration and obstetric complications are not significantly different in the three groups (misoprostol-dinoprostone-oxytocin).
Several treatment modalities for children suffering from monosymptomathic nocturnal enuresis are available including drugs, alarms, acupuncture, pelvic floor training and biofeedback. The aim of this study is to to test if Paula Method (circular muscle exercise) can be an another treatment modality.
Enemas are not anymore used routinely before vaginal deliveries.The intention of this study is to elucidate whether there is a benefit in routine use of enema before cesarean section.
