Cochrane Systematic Reviews, 17-Dec-2020
Age-related macular degeneration (AMD) is a highly prevalent condition in an ever-increasing elderly population. Although insidious in the early stages, advanced AMD (neovascular and atrophic forms) can cause significant visual disability and economic bur
- Visual feedback of individuals' medical imaging results for changing health behaviour
Cochrane Systematic Reviews, 20-Jan-2010
Feedback of medical imaging results can reveal visual evidence of actual bodily harm attributable to a given behaviour. This may offer a particularly promising approach to motivating changes in health behaviour to decrease risk. Applicable behaviours incl
- Visual inspection and dermoscopy, alone or in combination, for diagnosing keratinocyte skin cancers in adults
Cochrane Systematic Reviews, 4-Dec-2018
Early accurate detection of all skin cancer types is important to guide appropriate management, to reduce morbidity and to improve survival. Basal cell carcinoma (BCC) is almost always a localised skin cancer with potential to infiltrate and damage surrou
- Visual inspection for diagnosing cutaneous melanoma in adults
Cochrane Systematic Reviews, 4-Dec-2018
Melanoma has one of the fastest rising incidence rates of any cancer. It accounts for a small percentage of skin cancer cases but is responsible for the majority of skin cancer deaths. History-taking and visual inspection of a suspicious lesion by a clini
- Visual or visual‐tactile examination to detect and inform the diagnosis of enamel caries
Cochrane Systematic Reviews, 14-Jun-2021
The detection and diagnosis of caries at the initial (non-cavitated) and moderate (enamel) levels of severity is fundamental to achieving and maintaining good oral health and prevention of oral diseases. An increasing array of methods of early caries dete
- Vitamin A and beta (β)‐carotene supplementation for cystic fibrosis
Cochrane Systematic Reviews, 9-Aug-2018
People with cystic fibrosis (CF) and pancreatic insufficiency are at risk of a deficiency in fat-soluble vitamins, including vitamin A. Vitamin A deficiency predominantly causes eye and skin problems, while excessive levels of vitamin A can harm the respi

Cochrane Systematic Reviews, 23-Jun-2020
Retinitis pigmentosa (RP) comprises a group of hereditary eye diseases characterized by progressive degeneration of retinal photoreceptors. It results in severe visual loss that may lead to blindness. Symptoms may become manifest during childhood or adult
- Vitamin A for non‐measles pneumonia in children
Cochrane Systematic Reviews, 20-Jul-2005
Acute respiratory infections, mostly in the form of pneumonia, are the leading causes of death in children under five years of age in low-income countries. Some clinical trials have demonstrated that vitamin A supplementation reduces the severity of respi
- Vitamin A for preventing acute lower respiratory tract infections in children up to seven years of age
Cochrane Systematic Reviews, 5-Dec-2010
Vitamin A supplements are effective for preventing diarrhoea. There are theoretical reasons why they may also be effective for acute lower respiratory tract infections (LRTIs), also very common in children, especially in low-income countries.
- Vitamin A for treating measles in children
Cochrane Systematic Reviews, 19-Oct-2005
Measles is a major cause of childhood morbidity and mortality. Vitamin A deficiency is a recognized risk factor for severe measles infections. The World Health Organization (WHO) recommends a daily oral dose of vitamin A for two days to children with meas

Cochrane Systematic Reviews, 16-Mar-2022
Vitamin A deficiency (VAD) is a major public health problem in low- and middle-income countries, affecting 190 million children under five years of age and leading to many adverse health consequences, including death. Based on prior evidence and a previou
- Vitamin A supplementation for the prevention of morbidity and mortality in infants one to six months of age
Cochrane Systematic Reviews, 28-Sep-2016
Vitamin A deficiency is a significant public health problem in low- and middle-income countries. Vitamin A supplementation provided to infants less than six months of age is one of the strategies to improve the nutrition of infants at high risk of vitamin
- Vitamin A supplementation to prevent mortality and short‐ and long‐term morbidity in very low birth weight infants
Cochrane Systematic Reviews, 22-Aug-2016
Vitamin A is necessary for normal lung growth and the integrity of respiratory tract epithelial cells. Preterm infants have low vitamin A status at birth and this has been associated with an increased risk of developing chronic lung disease.
