Aim of prospective randomized a placebo controlled study is to prove that in case of acute surgical procedure due to appendicitis, ileus of small bowel and perforation of small bowel and stomach appropriately administered antibiotic prophylaxis is effective with lower incidence of infection in surgical site and comparable risk of development of other nosocomial infections versus group without antibiotic prophylaxis. Secondary aim is to determine risk of developing nosocomial infection in the above mentioned group of patients, identify group of patients which does not benefit from prophylaxis, and compile financial costs for antibiotic prophylaxis and treatment of nosocomial infections and thus the background for the recommended procedure with regards that such prospective study does not exist in the Czech Republic.
The objective of this study is to determine whether the finger tip images captured by the EPIC ClearView device, when analyzed via the ClearView software, produce a Response Scale that characterizes trends consistent with known diagnoses identified by medical doctors. Specifically, the investigators hypothesize that the organ system involving any of a series of known active diagnoses will be identified in the EPIC ClearView Response Scale report with the intention of providing potential triage capabilities.
1. Back ground Antibiotics resistance of Helicobacter pylori, especially to clarithromycin is one of the main causes of failure of eradication. 23S rRNA point mutation of Helicobacter pylori is associated clarithromycin resistance 2. Hypothesis If the investigators check the 23S rRNA point mutation then choose treatment regimens containing a proton pump inhibitor and combination of two antibiotics (amoxicillin and clarithromycin or metronidazole), the investigators will eradicate Helicoabacter pylori more successfully 3. Material & methods The investigators enroll patients diagnosed with peptic ulcer, endoscopically. Helicobacter pylori is documented with Urea breath test or silver staining biopsy specimen or polymerase chain reaction of biopsy specimen. Check the 23S rRNA A2142G/A2143G point mutation by polymerase chain reaction. If there is mutation, the investigators consider as resistance to clarithromycin and choose the treatment regimen containing a proton pump inhibitor, amoxicillin, metronidazole. If there is no mutation, choose the treatment regimen containing a proton pump inhibitor, amoxicillin, clarithromycin. Verify Helicobacter pylori eradication by urea breath test. Compare eradication rate with conventional treatment,proton pump inhibitor, amoxicillin, clarithromycin.
In a prospective randomised study design to investigate, if a systematic risk factor screening for bleeding ulcer in patients, who following percutaneous coronary intervention (PCI) commence a one year combination treatment with low dose aspirin and clopidogrel, followed by prophylactic treatment with a proton pump inhibitor (PPI) in case of increased risk, can reduce the risk of bleeding ulcer. Based on the recently raised suspicion that PPI's, possibly except pantoprazole, reduce the effect of ADP-receptor inhibitors, pantoprazole has been chosen as prophylaxis in the screening group, and analyses will be done to ascertain whether PPI treatment increases the risk of coronary events. Further analyses will be made to see whether PPI prophylaxis in high risk patients can increase compliance with the antithrombotic treatment through a reduction of side effects, thereby reducing the risk of myocardial infarction in particular stent thrombosis. The study population will be analyzed further to identify the patients, who will benefit the most from PPI prophylaxis Hypothesis: screening heart patients for risk factors for bleeding ulcer and subsequently treating high risk patients with PPI can reduce the incidence of bleeding ulcer and increase compliance with the antithrombotic treatment; thereby possibly reducing the risk of coronary events and improving survival. Initial a description of the prevalence of risk factors will be done.
This pilot study aims to estimate the prevalence of Helicobacter pylori (H. pylori) colonization in patients presenting with non-specific abdominal pain (NSAP) in an urban academic emergency department (ED) located in Washington, DC.
The researcher's primary hypothesis is that VCE allows for safe outpatient management of ED patients with suspected upper GI hemorrhage. A prospective multicenter randomized control trial was designed to investigate the safety of this approach.
Esomeprazole plus aspirin compared with esomeprazole alone for the treatment of aspirin-related peptic ulcers.
The objective of this study is to show that Hemospray is effective in achieving initial hemostasis and documenting rate of further bleed when compared to standard of care.
Rapid urease test (RUT) is the most commonly used biopsy-based method to diagnose Helicobacter pylori (Hp) infection because of its simple, rapid and accurate characters. However, its sensitivity was reported to decrease during ulcer bleeding recently. So it is an important issue to avoid a false negative test in these patients. Siddique et al reported that the sensitivity of RUT could be increased when the biopsy number increased from 1 to 4. Other studies demonstrated that additional biopsy from gastric body would increased the sensitivity of RUT in patients with ulcer bleeding. Therefore, we design this study to see if increased number of biopsy or different location of biopsy could increase sensitivity of RUT in patients with gastroduodenal ulcer bleeding. After receiving explanation and giving consent, these patients with gastric or duodenal ulcer bleeding diagnosed after endoscopic examination will be enrolled. Those who are unstable, have received antibiotic or continuous proton pump inhibitor treatment within 4 weeks, or are contraindicated for endoscopic biopsy will be excluded. We will take 1 piece, 4 pieces of biopsy samples from prepyloric antrum and 1 piece from gastric body with standard biopsy forceps from the patients after they agree for RUT test. Then, we put these samples into 3 separate RUT kits respectively. We use 13C-UBT as gold standard for diagnosis of Hp infection. It is scheduled: (1) if the condition of this patient is not suitable for breath test just after endoscopic examination, 13C-UBT will be performed within 2 days,(2) otherwise, it will be performed 1 hour after examination. We plan to enroll 100 patients for this study. We will apply McNamer's test to examine the difference of RUT sensitivity of different biopsy number. For the RUT sensitivity from different locations, we use kappa statistic method to analyze their consistency.
