The current standard of care at the Oral and Maxillofacial Department at the CDHA is the use of one gram of methylprednisolone administered intravenously prior to orthognathic surgery. This is largely based on the work of Habal. The administration of one gram of methylprednisolone can be concerning for the anesthesiologist since this is an unusually large dose of steroid in comparison to use in other surgical specialties. As with most medications, the chances of steroid-related complications increase with increasing doses of steroids. The researchers are proposing a prospective, double-blind randomized control trial to determine if a smaller dose of methylprednisolone (125mg) can be used safely and effectively instead of one gram of methylprednisolone.
this study was planned to investigate the antiinflammatory activity of preemptive intravenous ibuprofen on inflammatory complications such as edema and trismus after third molar tooth surgery
AURIGA is designed to collect data from routine clinical practice on the effectiveness and utilization of intravitreal aflibercept in the treatment of visual impairment due to diabetic macular edema (DME) or macula edema secondary to retinal vein occlusion (RVO). The primary objective of this observational study (OS) is to evaluate the effectiveness of intravitreal aflibercept in 4 cohorts (with/without prior treatment in DME or macular edema secondary to RVO) in each of the participating countries. Additionally, utilization and treatment regimens in routine clinical practice will be described. Health care resources and services as well as health out-comes related to vision loss will be evaluated based on information collected using the AURIGA patient questionnaires.
This is a randomized, double-blind, placebo-controlled trial to evaluate the safety and efficacy of levosulpiride to improve retinal alterations due to diabetic macular edema and diabetic retinopathy
Persistent swelling (chronic oedema), e.g. of the legs, is quite a common condition, which can cause a number of problems, including infections (cellulitis) in the swollen area and ulceration. It seems to be particularly common in people who are overweight but this has not been studied in detail. This study aims to address this gap in knowledge. It will take place in two stages, running in parallel to each other with different groups of patients. The first stage will determine how common persistent swelling is among patients attending weight management services at the Royal Derby Hospital and how it impacts on every day life. The second stage will determine whether weight loss surgery improves the swelling. The results will inform future treatment guidelines for overweight patients who have swelling. They will also inform the design of future research that will investigate the effects of weight loss surgery in more detail, for example by testing out methods of measuring fluid changes in the legs. All new patients attending the weight loss service will be eligible to take part in the first stage of the study, as long as they: give their informed consent to take part, and can speak English (or have someone with them who speaks English). Participants will not have had weight loss surgery previously. The Stage 1 assessment is expected to take about 40 minutes and consists of: a single clinical assessment for each participant to identify the presence of the swelling and its degree in each of the affected areas and, up to 3 questionnaires concerning their quality of life and mobility. Patients attending the programme, who have been referred for bariatric surgery, will take part in the second stage of the study. Stage 2 will last approximately 13 months, during which time the participants will be assessed 4 times - once before surgery and at 3, 6, and 12-month intervals after surgery. Each Stage 2 assessment is expected to take about 50 minutes and consists of: a clinical assessment and up to 5 questionnaires.
The goal of this pilot study is to investigate the safety and efficacy of micropulse (MP) macular laser in combination with intravitreal aflibercept for the treatment of centre-involved diabetic macular edema.
Persons exposed to infrasound - frequencies below 20 Hz - describe a variety of troubling audiovestibular symptoms, but the underlying mechanisms are not understood. Recent animal studies, however, provide evidence that short-term exposure to low frequency sound induces transient endolymphatic hydrops. The existence of this effect has not been studied in humans. The long-term objective of this research is to identify a possible mechanism to describe the effects of infrasound on the human inner ear. The central hypothesis of the proposed study is that short-term infrasound exposure induces transient endolymphatic hydrops in humans. This will be tested by performing electrophysiologic tests indicative of endolymphatic hydrops among normal hearing individuals before and immediately after a period of infrasound exposure. Recordings of infrasound generated by wind turbines in the field have been established and calibrated by this team of engineers, otologist, and hearing and balance scientists. An infrasound generator reproduces the acoustic signature based on these field recordings. Aim 1: Determine the effect of infrasound on the summating potential to action potential (SP/AP) ratio on electrocochleography (ECoG). Hypothesis 1: Infrasound exposure will cause a reversible elevation of the SP/AP ratio. Aim 2: Determine the effect of infrasound on the threshold response curves of ocular and cervical vestibular evoked myogenic potentials. (oVEMP and cVEMP). Hypothesis 2: Infrasound exposure will cause elevation of the oVEMP and cVEMP thresholds at the frequency of best response. Successful completion of the aims will provide evidence for a possible mechanism of the effect of infrasound on the inner ear. This understanding will benefit individuals exposed to environmental infrasound and those in regulatory, research, and advocacy roles when crafting interventions and future policy.
The purpose of this trial is to evaluate the safety and efficacy of suprachoroidal CLS-TA used with intravitreal aflibercept in subjects with DME.
High altitude pulmonary edema is a life-threatening condition that remains a concern for climbers and clinicians alike. It is defined as a non-cardiac pulmonary edema occurring at altitudes exceeding 3000m in non-acclimatised individuals. Recently, studies conducted in remote areas have demonstrated that ultrasound lung comets (B lines) can be used as a measure of sub-acute pulmonary edema and high altitude pulmonary edema in climbers ascending to altitude. the investigators want to assess the occurrence of of comet tails (B lines) as a measure of pulmonary edema among patients after lung transplantation and healthy individuals during an expedition to Mount Kilimanjaro.
