Filter by:The goal of this observational study is to learn about long term symptoms in oesophageal cancer survivors. The main question it aims to answer is are: - Study the changes in gut bacteria by examining saliva, stool and blood. - Investigate the products of bacteria in breath to develop a non-invasive breath test to detect the changes in gut bacteria. - Develop new strategies to treat this change and trial new treatments to improve quality- of-life in oesophageal cancer survivors. Participants will attend an outpatient clinic, fasted for at least 4 hours for collection of breath, saliva, blood, urine, stool and complete validated healthy-related quality-of-life questionnaires. Researchers will compare symptomatic and asymptomatic participants to detect the changes stated above.
Orthodontic treatment is an elective procedure to improve the patient's dentofacial appearance. The complex design of fixed appliances provides a platform that leads to increased plaque accumulation around orthodontic brackets. So, the risk to develop demineralization area adjacent to orthodontic brackets is a major barrier in achieving this goal. Oral hygiene is greatly complicated following the placement of fixed orthodontic Appliances. Molar tube in place are considered for nearly all patients experiencing fixed orthodontic therapy over the whole treatment period, which normally lasts 1.5 to 2 years. To the best of the authors' knowledge, the application and antimicrobial efficacy of zinc oxide (ZnO) nanoparticles coating on orthodontic molar tube material has not been integrated clinically. White spot lesions during orthodontic treatment have a documented etiology. Briefly, the accumulation of plaque and food around brackets, bands, wires, and other attachments caused decreased pH and increased S. mutans colonization, which led to the possibility of clinical demineralization. The aims of study are to assess the antimicrobial effect of nanoparticle coated stainless steel orthodontic molar tube material (OMT) with zinc oxide (ZnO) nanoparticles in relative to uncoated orthodontic molar tube (UOMT) against the streptococcus. mutans& lactobacllius bacteria that cause white spot lesion around the fixed orthodontic appliance. .
Twelve patients with blue sweat (infectious pseudochromhidrosis) caused by Bacillus cereus.
Children with intestinal failure have a lack of tolerance for food in the intestine. The children are dependent on intravenous nutrition over a long period of time period to ensure growth and development. The condition is characterized by bacterial overgrowth in the intestine, with nausea, vomiting, diarrhea and flatulence as physical symptoms. Mental health is affected in the form of lower quality of life, lack of school participation and less social contact with peers. The investigators own (unpublished) data show that children with intestinal failure have a lower quality of life than healthy people. Standard treatment is antibiotics, but the effect of these is short-lived, and many must have repeated courses. Prebiotics are indigestible carbohydrates (fiber) in foods that positively affect the bacterial flora and promote intestinal health. In this project the investigators want to see if supply of prebiotics can change the bacterial balance, reduce symptoms of bacterial overgrowth and increase quality of life. The study is unique, as Prebiotics have not previously been used in the treatment of intestinal failure. If successful, it can pave the way for a new and better treatment method that can potentially be transferred to other conditions with imbalance in the intestinal flora. The study is a randomized intervention study and is consist of two phases. In phase 1, the effect of 4 weeks of open intervention with prebiotics is studied to establish so-called "proof of concept". Data from phase 1 are used to look at connections between the composition of intestinal flora, nutritional status and bowel function. The intervention involves the use of a prebiotic product (Stimulance, Nutricia), which is added to childs regular food. In phase 2, patients are randomized into two groups. One group will continue with the product for 6 months, while the other group does not receive prebiotics.
The purpose of this study is to evaluate the residual antimicrobial efficacy of one test product as defined by the difference between the number of a challenge bacterial species recovered following exposure to the test product and the number recovered when untreated (negative control). The challenge bacterial species to be used is Staphylococcus aureus (ATCC #6538) (S. aureus). Testing will be carried out using a modification of the standardized test method described in ASTM E2752-10 (2015) Standard Guide for Evaluation of Residual Effectiveness of Antibacterial Personal Cleansing Products. Bacterial recoveries will be assayed after application oftest material, using the forearms as a substrate.
The purpose of this investigation is to conduct a randomized controlled trial within a subgroup of difficult-to-treat patients with CRS, evaluating the use of topical xylitol treatment concurrently with topical steroid/antibiotics combination in the effort to disrupt biofilms and improve disease control. The effectiveness of topical surfactants is a research gap in treating CRS but has promising correlates in other medical fields. Specifically, the investigators will be studying the effect of topical xylitol therapy on biofilm production with the use of PCR bacterial sequencing before and after medical intervention.
