The overall cost of chronic pain is estimated at around 300 billion euros in the EU. Unfortunately, current treatments for chronic pain have limited effectiveness. Pain clinics, which support the most c...
In this study, the investigators provide participants who had congenital cataract the multifocal contact lenses and bifocal spectacles in the purpose of seeking out a better way to make a definite diagnosis with high efficiency and accuracy, and report a prospective, randomized controlled study aiming at comparison of multifocal contact lenses and bifocal spectacles.
The purpose of this study is to evaluate the effect of +3.00ADD vs single vision spectacle on the progression of myopia in children. Many studies applying bifocals or multifocal spectacles to intervene the progression have been carried out based on the idea that myopia was caused by excessive accommodation, however, the effect was limited. The possible reason is that bifocal or multifocal spectacles still not fully adjust the accommodative error in myopia children.
Diarrhea is one of the most common reasons for people to seek medical advice - but it can range from being a mild, temporary condition, to be life threading condition. It is estimated that there are 2 billion cases of diarrheal disease every year globally, and that 1.9 million children below the age of 5 years, mostly in developing countries, die annually.
Myopia is equivalent to the colloquial term known as near-sightedness. This, in short, means that the image of one's environment is projected in front of the retina (rather than directly on the retina, which is ideal). Of course, glasses can be used to correct the image disparity that is created by being near-sighted (that is why a lot of people need glasses for blurry vision). However, glasses and spectacles and contacts do not correct the underlying problem. Most near-sighted...
This study is planned to test an educational intervention promoting the use of spectacles among secondary school children. It is based on the hypothesis that educating teachers, parents and children about the importance of wearing spectacles has the potential to increase spectacle wear among children.Reasons for non-compliance towards spectacle use will be explored and educational intervention will be planned considering these reasons. Educational intervention will increase awa...
Some programs do the screening, refraction testing and provision of spectacles to children entirely in the school setting ("School Model"). One strength of such programs are that most children at school who need spectacles get them. However, sustainability is poor, because spectacles cannot be sold in many schools and there may be too few refractionists to cover all schools in most countries. Other programs provide vision screening at schools but refer children who fail vision ...
Objective: To coordinate active tracing of chronic hepatitis C patients lost to follow-up to inform them about there disease severity and treatment options. Study design: This is a prospective cohort study, which will start as a pilot study in the Radboudumc Population: lost to follow-up chronic hepatitis C patients in the region Nijmegen. This so-called lost population consists of all patients, that in the past have been identified at the Radboudumc but who are current...
Over 1 billion people worldwide smoke, resulting in an estimated 4 million deaths annually from smoking-related disease.1 Persistent and long-term smoking leads to an increased risk of cardiovascular damage, respiratory disease, and a higher incidence of a variety of cancers; but for smokers who can quit there is an immediate and significant beneficial impact on their health and life expectancy. Cigarette smoking remains the leading preventable cause of death in the United Stat...
Worldwide, headache disorders are among the most common medical conditions. Many people with headache need not experience further pain if the diagnosis and treatment are correct. Most patients do not have correct diagnosis and treatment. This study tested a model for treatment of people with headache disorders at primary health-care level in rural areas of Haryana, India.
The trial aims to evaulate the possiblity that use of virtual reality spectacles will affect post operative pain in total knee arthroplasty patients. The trial is a single center open label design. Patients will be randomized into two arm study comparing the effect of the use of virtual reality spectacles on pain levels and analgesic consumption in the perioperative period. The controls shall receive standard post operative care. The endpoints are VAS levels and analgesic use.
The primary objective of this study is to evaluate the efficacy of the Avulux device in reducing the impact of migraine headaches as measured by improvement in Headache Impact Test (HIT-6TM) scores at three weeks when compared to a control/sham device.
The objective of this short-term, pilot randomized trial comparing spectacles with relieving prism to spectacles without prism is to determine whether to proceed to a full-scale, longer-term randomized trial. This decision will be based primarily on assessing the initial (8-week) response to prism by comparing treatment groups on the following outcomes: - Mean distance intermittent exotropia (IXT) control score (the mean of 3 control scores) (primary outcome) ...
A brain PET scan is recognized as "reasonable and necessary" for some patients with "a recently established diagnosis of dementia" (Centers for Medicare and Medicaid Services, Decision Memo CAG-00088R, 2004), but evidence is less clear for patients having less severe cognitive problems. A substantial portion of such patients will develop Alzheimer's disease and other forms of dementia, which affect millions of people in the U.S., costing us over $100 billion annually. This proj...
The aim of this work is to investigate the clinical performance and subjective acceptance of the comfilcon A asphere contact lens when compared to single-vision spectacles in subjects who have never worn contact lenses and who use digital devices (such as phones, tablets, laptops, desktop computers) for at least 4 hours per day on at least 5 days per week.
Blindness and visual impairment severely impact the visual health and life quality of people, particularly the 2.566 million senior citizens aged at 65 and above in Shanghai. The main reason is uncorrected refractive error, of which, 62.1% can be solved through refractive correction. For this reason, the uncorrected refractive errors of 154,000 senior citizens in Shanghai can be taken as a priority among the public health issues to prevent blindness. Now, with the aim to reduce...
Traumatic brain injury (TBI) is the leading cause of death or disability in children. Each year in the United States, pediatric TBI results in an estimated 630,000 emergency room visits, 58,900 hospitalizations, and 7000 deaths. The incidence of long-term disability after severe TBI is high, with over 60% of children requiring educational or community based supportive services 12 months post-injury. Over 5,000 children require inpatient rehabilitation after TBI each year and an...
The purpose of this trial is to compare the functional visual performance of Precision Profile Multifocal (MF) contact lenses to Progressive Addition Lens (PAL) spectacles in a presbyopic population.
The main objectives of this randomized trial comparing overminus lens treatment to non-overminus (spectacles without overminus or spectacles with plano lenses) are to determine: - The long-term on-treatment effect of overminus treatment on distance IXT control score. - The off-treatment effect of overminus treatment on distance IXT control score (following weaning and 3 months off treatment).
Asthma is one of the four most common chronic disorders in adults, affecting 14 million adults in the United States and costing an estimated 7.9 billion dollars in medical care and 5.3 billion dollars in lost work or school. About 40% of asthmatics report using some form of complementary and alternative medicine approach to help reduce their asthma symptoms, but there is little evidence for their effectiveness. Mindfulness-based stress reduction (MBSR) is a group based progra...
