To evaluate the efficacy and safety of fixed combination of azithromycin 1.5% + 0.5% Loteprednol eye drops for the treatment of ocular inflammation and infection associated bacterial blepharitis and / or keratitis and / or conjunctivitis compared with the individual administration of azithromycin 1.5% and 0.5% Loteprednol (separately).
ROLE OF SUCTION IN EUS-FNA: Current suction technique involves suctioning the aspirate into the needle that has an air column. The needle is not flushed with any liquid prior to passing into the desired solid lesion. Suction is applied when the needle is within the lesion leading to aspiration of tissue into the needle. This is the standard technique and some have done with and without the stylet. There are some data that favor non use of a stylet. WET SCTION TECHNIQUE: Wet suction technique involves flushing the needle with 1-2 cc of saline to replace the column of air with saline. The needle is now passed into the desired lesion. Suction is applied at maximal strength and needle moved back and forth within the lesion to obtain as aspirate. Drops of saline can be seen moving into the suction syringe as the aspirate moves into the needle. Needle is now withdrawn and aspirate delivered on to a slide by using a stylet and or flushing air into the needle with a syringe. HYPOTHESIS The effect of suction for the purpose of aspirating cells and / or tissue during fine needle biopsy may be significantly improved by filling the column of the needle with a less compressible fluid. The volume of vacuum being pulled may be negatively impacted by the expansion of air within the needle. Replacing the air with sterile saline may thus improve the suction transferred to the needle tip by ensuring that the full volume of the vacuum syringe is transferred to the distal tip of the needle. This effect would be most pronounced in larger gauge needles which would have a larger internal volume. An additional benefit of filling the needle with saline prior to aspiration is the speed of the pressure transfer. The theory is that the air in the needle may absorb some of the force of the sudden application of vacuum. A column of saline in the needle may increase the velocity of the pressure transfer providing more tissue and less blood.
The purpose of this study is to investigate the local and systemic inflammatory response and haemostatic alterations in the lungs after lipopolysaccharide (LPS) instillation and to determine the feasibility of imaging techniques to quantify lung inflammation in an adapted human endotoxin instillation model. The investigators will also explore whether glucocorticoid treatment can blunt LPS effects.
Hypothesis: aspirin attenuates inflammation in cerebral aneurysms and hence reduces the incidence of rupture. This effect can be monitored using the signal generated by macrophages (inflammatory biomarker) in ferumoxytol-enhanced MRI. Study aims: 1. Determine if daily aspirin intake (for three months) would obliterate/reduce ferumoxytol-enhanced MRI signal changes generated by macrophages in cerebral aneurysm wall. Fifteen patients with cerebral aneurysms > 7 mm will be selected to enroll in this pilot study. 10 patients will be imaged at base line with ferumoxytol-enhanced MRI. Following that, they will take aspirin 81 mg daily and then re-imaged again at three months. This group will be compared to a control group of 5 patients where they will have the imagings studies performed at base line and at three months but will NOT take aspirin.
This trial is conducted in Europe. The aim of the trial is to investigate the effect of recombinant factor XIII (rFXIII) administered to subjects with mild to moderate active ulcerative colitis (UC).
The purpose of the study is to investigate the metabolic effects during acute inflammation with and without the nutritional supplement of amino acids. E. Coli Endotoxin (LPS, lipopolysaccharide) is used to initiate an inflammatory response. The study is an interventional randomized placebo study including 8 healthy male subjects. Each subject participates 3 times (different days) and are given one of following interventions: - Placebo (NaCl) - Endotoxin, US standard reference E.Coli + Placebo (NaCl) - Endotoxin, US standard reference E.Coli + Amino acids (intravenously) It is our hypothesis that the nutritional intervention during acute inflammation plays an important role in lipid and protein metabolism.
Patients with chronic obstructive pulmonary disease, also known as COPD or emphysema, is like any other with a chronic illness not only affected by the physical discomfort the illness gives. For COPD patients that is: accelerated loss of lung function, conditioning and increased mortality: 25% of patients hospitalized with COPD exacerbation die 12 months later. Patients are also characterized by various psychological factors such as reduced quality of life, depression, etc. Therefore, everywhere in the country newly diagnosed COPD patients are offered rehabilitation in Region Zealand which consists of 10 weeks of classes 2 hours, 2 times a week with physical exercise, smoking cessation, medication, nutrition education and psychosocial support and patient education based on the National Health Service and international recommendations. In the literature, the effect of rehabilitation on quality of life was measured using a questionnaire (St. George Respiratory Questionnaire (SGRQ)), and the increase in function has been measured using a walk test, but there are no studies which look at the effect on inflammation lungs. It is important for COPD patients is to prevent exacerbations of the disease, which sometimes requires hospitalization and sometimes treated by their own doctor. It has been proven that inflammation in the lungs is associated with disease severity and exacerbation frequency, and therefore we would like to investigate whether both rehabilitation, close monitoring of patients with time in the pulmonary clinic every 3 months, and instruction in self-administration of medication (antibiotics and corticosteroids) have an effect on especially inflammation in the lungs, number of exacerbations, mortality, lung function and walking capacity.
Abstract: Fatty liver most frequently corresponds to a fat overload of the liver. It is usually classified as alcoholic steatosis or non-alcoholic steatosis. In the case of non alcoholic fatty liver overload, the histological spectrum ranges from simple steatosis to steatohepatitis (NASH) which associates inflammation to steatosis, with a risk of progression to fibrosis and cirrhosis. Obese patients are at particular risk of NASH. Screening of these hepatic lesions is difficult especially as they may exist while the liver tests are normal. The diagnosis of NASH is currently done by liver biopsy, which exposes them in particular to the risk of hemorrhagic complications. Number of subjects required: According to the literature and data collected Louis Mourier in the recent years, the inclusion of 200 patients would examine 20-40 patients with severe histological steatosis and steatohepatitis. All patients will be included in Louis Mourier hospital. Follow-up: one month Search duration: 37 months Duration inclusions: 36 months The total duration of participation for a patient will be one month. Methodology: It is a monocentric, prospective study evaluating the value of noninvasive tests for the diagnosis of hepatic lesions in morbid obese patients. The "open " MRI system allows access to MRI for all obese patients (maximum weight 250 kg). Three of such systems are available in France and liver pathology can be explored only on the system of Louis Mourier. The reference method is liver histology; studied tests are abdominal MRI, Fibroscan / CAP, and serum tests. Examinations required specifically for research Examinations required specifically for the research is abdominal MRI, FibroScan/ CAP and serum tests. Primary endpoint : To validate the use of abdominal MRI, the FibroScan/ CAP and serum tests for finding severe steatosis and / or NASH, specificity, sensitivity, positive and negative predictive values of these tests are calculated. The gold standard is the result of histology on liver biopsy, with a morphometric study of these parameters. ROC curves are used to determine the best compromise between sensitivity and specificity. The secondary endpoints were: Histological lesions of liver fibrosis. Quantification of abdominal fat by MRI (in the form of three variables of interest: quantification of the surface of the visceral fat, of subcutaneous fat and of intrahepatic fat assessed by the percentage loss of signal
Our study addresses the following research question: What is the role of obesity in modulating inflammation and innate immune function, as well as the overall responsiveness of innate immune cells (such as macrophages, neutrophils, and other peripheral leukocytes) in patients undergoing peritoneal dialysis? The investigators hypothesize that obesity will lead to increased inflammation in patients undergoing peritoneal dialysis.
