Participants will receive a skin prick test with the skin prick automated test device including 22 allergens and 2 controls on both forearms.
Uterine leiomyomas (fibroids or myomas) are benign, smooth muscle tumors of the human uterus. Most myomas are asymptomatic (symptomless) and are discovered incidentally during a routine pelvic examination or imaging studies and have a lifetime incidence of approximately 70% in the general population . However, Approximately 20-40% of women with fibroids experience significant symptoms and consult gynecologic care. The most common clinical symptoms include abnormal uterine bleeding, dysmenorrhea, pelvic pain, infertility, and recurrent pregnancy loss The standard treatment of symptomatic leiomyomas is Abdominal myomectomy Blood loss during myomectomy can be intra-operative or postoperative and with hematoma formation. The average volume of blood loss during abdominal myomectomy is 200 to 800 ml. massive blood loss associated with the dissection of huge fibroids renders myomectomy a more technically challenging procedure than hysterectomy. Sometimes myomectomy is converted to hysterectomy intra-operatively when bleeding becomes heavy and uncontrollable or when it is impossible to reconstruct the uterus because of the many defects left by removal of multiple myomas . Many techniques are used to reduce blood loss during myomectomy; preoperative measures such as correction of preoperative anemia associated with menorrhagia may be treated with iron supplementation, use of gonadotropin (GHG) triggers prior to surgery. Intra-operative measures as use of tourniquet around the uterus during the operation, injections of Vasopressin or other vasopressors as epinephrine in the uterine muscle and use of ecbolic (misoprostol, oxytocin, and carbetocin etc.). Uterine artery ligation, embolization, or internal iliac artery ligation may also be used to avoid hysterectomy when heavy bleeding is anticipated or occurs during myomectomy
A dental gel intended to relieve pain related to dentin hyper sensitivity is commercialized in several countries worlwide since May 2017. Its efficacy and tolerance has already been proven in dentin hyper sensitivity. In this new study, we assess the efficacy and tolerance of this tested product in a specific external agression, the teeth whitening.
The aim of this thesis study is to determine the effect of compassion education on compassion adequacy and moral sensitivity in nursing students. The sample of the descriptive study consists of the first year nursing students studying at Süleyman Demirel University in the 2022-2023 academic year. The research will be carried out between October 2022 and September 2023. Research data will be collected from nursing students who volunteered to participate in the research by using the Personal Information Form, which includes the demographic characteristics of the students, the Compassion Adequacy Scale and the Modified Moral Sensitivity Scale for Nursing Students.
Irritable bowel syndrome (IBS) affects one in seven people with gastrointestinal (GI) symptoms. IBS strongly impacts quality of life, is a leading cause of work absenteeism, and consumes 0.5% of the healthcare annual budget. It manifests in women more than men with symptoms including abdominal pain, bloating, constipation (IBS-C), diarrhoea (IBS-D), and mixed presentations (IBS-M) (1). The development of therapeutic options is hampered by the poor understanding of the underlying cause of symptoms. Many patients find that certain foods (particularly carbohydrates) trigger their symptoms, and avoiding such foods has been shown effective in IBS, like in the low-FODMAP (fermentable oligo-, di-, mono-saccharides and polyols) exclusion diet. This has suggested that the food-symptom relation may involve malabsorption of carbohydrates due to inefficient digestion. However only a percentage of patients respond to this diet. Recently it has been reported that a subset of IBS carries hypomorphic (defective) gene variant of the sucrase isomaltase (SI), the enzyme that normally digests carbohydrates, sucrose and starch. This carbohydrate maldigestion (the breakdown of complex carbohydrates by a person's small bowel enzymes) is characterized by diarrhoea, abdominal pain and bloating, which are also features of IBS. This possibly occurs via accumulation of undigested carbohydrates in the large bowel, where they cause symptoms due to gas production following bacterial fermentation. Similar mechanisms may be acting at the level of other enzymes involved in the digestion, breakdown and absorption of carbohydrates (carb digestion genes -CDGs). Aim of the study is to study the prevalence of this genetic alteration in a large number of IBS patients as compared to asymptomatic controls.
Studies in the literature suggest that people with obesity have an excess of stored iron. There is possibly an inverse relationship between ferritin levels and the actions of insulin on glycemic control. The reduction of stored iron by simply donating blood could result in improvements in glycemic control in people with obesity and prediabetes. We propose, to reduce ferritin levels through a standard donation of a unit of whole blood, and to measure if it positively affects glycemic control.
There are a lot of parents who believe that their child may not tolerate cow's milk because they develop symptoms such as redness of the skin or they may vomit. It is not always easy to find out if these infants should indeed avoid drinking cow's milk or that the symptoms are caused by something else, for instance because they have a viral illness. The goal of the investigators is to find out if cow's milk should be introduced in the hospital or if it can also be advised to perform the introduction at home to determine if an infant can drink cow's milk without developing symptoms. Half of the participants will drink cow's milk in the hospital. This test is performed on two days. On one of the days cow's milk will be offered. On the other day a look-alike substance is offered. The other half of the participants will drink cow's milk at home by starting to drink a little bit of milk and in a few steps drink a normal bottle of cow's milk. The main question is whether both tests can be used to find out if an infant can drink cow's milk without developing symptoms.
The goal of this randomized, double-blind, placebo-controlled study is to investigate the effect of expectancy related to gluten consumption versus actual gluten intake on overall GI symptoms in individuals with non-coeliac gluten sensitivity (NCGS) The main questions it aims to answer are: - what is the effect of consumer expectancy, related to either gluten-containing or gluten-free oat bread, on short-term (within 8 hours) overall GI symptoms in individuals with NCGS? - what is the effect of actual gluten intake on short-term (within 8 hours) overall GI symptoms in individuals with NCGS Participants will be randomised into four groups: 1. Participants with the expectation of receiving gluten-containing bread and actually receiving gluten-containing oat bread during the test day. (E+ G+) 2. Participants with the expectation of receiving gluten-containing bread, but actually receiving gluten-free oat bread during the test day. (E+ G-) 3. Participants with the expectation of receiving gluten-free bread but actually receiving gluten-containing oat bread during the test day. (E- G+) 4. Participants with the expectation of receiving gluten-free bread and actually receiving gluten-free oat bread during the test day. (E- G-)
The purpose of this study is to investigate differences of the bowel wall thickness visible in conventional ultrasound and bowel perfusion using quantitative Contrast-Enhanced Ultrasound in patients with Crohn´s disease in comparison with healthy controls and patients with food allergy.
The goal of this clinical trial is to evaluate the effect of 3M™ Clinpro™ Fluoride Aqueous Solution (experimental) on Dentin Hypersensitivity (DHS) in comparison to 3M™ Vanish™ (commercialized, control] in patients who have DHS. Participants will be asked to complete the following activities: Undergo a pre-treatment washout period for 3- to 6-weeks (± 4 days) post-enrollment. During this time, the Subject is to only use the provided oral hygiene products. Hypersensitivity will be assessed prior to (baseline) and immediately after sample application. Subject will be asked to come to the facility for hypersensitivity assessments at 24 hours, 7 days, and 30 days after the treatment visit. Researchers will compare 3M™ Clinpro™ Fluoride Aqueous Solution to 3M™ Vanish™ to evaluate if the effect of Clinpro™ on DHS treatment is non-inferior to Vanish™.
