Nutritional and household risk factors for xerophthalmia in Ache, Indonesia: a case-control study

Article Abstract:

Xerophthalmia is a condition that occurs when the membranes of the eyes become very dry. It can be caused by vitamin A deficiency and it is the main cause of blindness in children living in underdeveloped regions of the world. It is now becoming apparent that vitamin A deficiency is much more common in these parts of the world than it was previously thought. Vitamin A deficiency can be corrected by taking vitamin supplements or by eating foods that contain vitamin A. Previous studies have reported that children with xerophthalmia are weaned from breast feeding earlier and eat fewer foods rich in vitamin A than children who do not develop xerophthalmia. To identify other risk factors that may be associated with the development of xerophthalmia, 466 children living in the Province of Aceh, Indonesia were studied. Two percent of the children had xerophthalmia and 38 percent had night blindness. Xerophthalmia was most common in children from households with lower social and economic status and poorer hygiene. The risk of developing xerophthalmia was greater for those who consumed fewer green leafy vegetables and yellow fruits. Not eating any green vegetables or yellow fruits increased the risk of developing xerophthalmia by two-to-nine times. It is concluded that xerophthalmia is associated with vitamin A deficiency during weaning and early childhood. (Consumer Summary produced by Reliance Medical Information, Inc.)

Sun factors

Article Abstract:

Doctors report over 40,000 cases of skin cancer annually in the UK. These are of many different types, including nodular melanoma and squamous cell carcinoma, but they can all be classified as either melanoma or non-melanoma. Over 80% of skin cancers are preventable through the avoidance of excessive exposure to sun, and early diagnosis and treatment improve the survival rate. Patients with tumours of a thickness below 1.5mm have a five-year survival rate greater than 90%. Treatment options depend upon a range of factors but the aim is for complete tumour removal before the onset of metastases.
