Active clinical trials for "Hypersensitivity"

Stereotactic radiation therapy is an important and common method of treating brain metastases in patients with malignant disease. Today, however, there are no methods available to determine the metastasis' radiation sensitivity in advance and treatment responses can only be seen by changing of the size of the metastasis on conventional X-ray examinations, computed tomography (CT) and magnetic resonance imaging (MRI). Changes in the size of the metastases is something that is often seen weeks / months after treatment is completed. At Lund University Hospital, a new imaging technique, diffusional variance decomposition (DIVIDE), has now been developed. With this technique, the scatter in isotropic and anisotropic diffusion can be measured for each measuring point, which provides significantly more information about the properties of the tissue compared to current methods.

Wound complications can be devastating following total joint arthroplasty, resulting in an increased practice burden in the form of more frequent follow ups, increased clinic visits potential for wound dehiscence, superficial infection and deep infection with possible return to the operating room and revision surgery. Several dressing options are currently on the market designed to minimize wound complications in addition to traditional dressings, including negative pressure dressing, antimicrobial dressing, occlusive dressings, and/or skin adhesives. Prineo dressing (2-octyl cyanoacrylate adhesive (Dermabond) and n-butyl-2-cyanoacrylate adhesive) has increased in popularity as a dressing option used by joint arthroplasty surgeons. There is a well-documented adverse allergic response with these dressings resulting in peri-incisional erythema, urticaria, and/or an eczematous skin reaction. Recently, Mayman et al reported a rate of 1-1.5%, suggesting a possible rising incidence of ACD attributable to increased utilization of the specific dressing and sensitization. To our knowledge, no prospective trial has compared the rates of adverse allergic reactions in Prineo naive patients to patients who have undergone previous total joint arthroplasty (TJA) and received Prineo dressings in the past. We will utilize a prospective controlled study design to assess the rate of adverse allergic reactions in patients naive to Prineo versus those with previous exposure. We will assess rates of allergic reactions at one week post-op and at their first post-op clinic visit, 2 to 3 weeks post-op, tracking rates of allergic reactions as well as severity, the use of post-operative antibiotics, work up for prosthetic joint infection, return to the operating room, surgical site infection, confirmed prosthetic joint infection and stiffness requiring manipulation under anesthesia.

The goal of this prospective mono centric study is to identify relevant commercially available allergen extracts for allergy testing in soldiers prepared for international mission. Participants will receive a skin prick test with the skin prick automated test device including 22 allergens and 2 controls on both forearms.

The aim of this multi-surgeon, single institution study is to prospectively evaluate the incidence of allergic contact dermatitis (ACD) following application of AQUACEL Ag, a silver-containing hydrofiber dressing, in total hip and knee arthroplasty patients. Arthroplasty-naïve patients will be compared to prior total joint arthroplasty patients who received a Aquacel dressing postoperatively.

Prospective Phase 1 clinical trial providing proof of concept data on boiled peanut oral immunotherapy (OIT) for the treatment of peanut allergy in children. The investigators hypothesize that the proportion of subjects successfully desensitized with boiled peanut OIT is greater than the theoretical placebo rate of 20%.

The purpose of this research is to learn about how salt in the diet influences blood pressure in young adults who were born prematurely.

The assessment of respiratory muscle function is critical within both clinical and research settings. Tools for the assessment of respiratory muscle function are especially useful in diagnosing, phenotyping, understanding pathophysiology, and assessing treatment responses in patients with respiratory symptoms, including critically hill patients and patients with respiratory and/or neuromuscular diseases. Respiratory muscle function is most commonly assessed using flow (i.e. spirometry) and pressure measurements during spontaneous ventilation, voluntary respiratory efforts, or artificially evoked responses using magnetic or electrical stimulation. Some of these approaches may be limited within patients suffering from neuromuscular diseases. The study hypothesis is the 18F-FDG PET technology, heavily used for clinical oncology purposes (diagnostic, staging, response to treatment, prognosis), could be an interesting alternative to invasive measurement of the respiratory muscle activity. In addition, it may contribute to further validate metrics based on multiparametric ultrasound imaging.

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.

This clinical trial aims to test the effect of double surgical gloves worn in different sizes on the surgical team's comfort, sensitivity, and dexterity.

The ADAPT study is an observational study of apalutamide, which can be given to patients with hormone sensitive metastatic prostate cancer as standard of care. The clinical decision for patients to have apalutamide as part of their management plan will be decided by the clinician. The patient will only be approached about the ADAPT study if they decide they want to have apalutamide as part of their management. The aims of the ADAPT study include documenting the biochemical effectiveness, as determined by the Prostate-Specific Antigen (PSA) and impact of apaluatmide on health related quality of life. The blood test for PSA is regularly monitored as standard of care. Additionally, the impact of apalutamide on fatigue, cognitive function, patients reported outcomes, health related quality of life will be evaluated using patient questionnaires answered at defined timepoints. The questionnaires will be sent either electronically or via post at week 12, 24, 36, 48, 72 and 104 weeks after commencement of apalutamide. Currently, the majority of data regarding tolerability and biochemical response to apalutamide has been from large phase III trials, where there are strict eligibility criteria. Real-world data as from the ADAPT study can provide valuable complementary data to randomised controlled trials, which can be used to address the 'generalizability' limitations of randomised control trials and can provide evidence on the external validity of their findings. This information can advance knowledge of patterns of care, treatment effectiveness and side-effects and inform clinical practice to improve outcomes.
