INTRODUCTION: The relative frequencies of the causes of hypernatraemia in children after the neonatal period are unknown. Salt poisoning and osmoregulatory dysfunction are extremely rare and potentially fatal. In this retrospective 10-year study, the incidence, causes and differential biochemistry of hypernatraemia in children is examined. METHODS: Children with hypernatraemia (sodium ≥150 mmol/litre) aged >2 weeks [...]

This study investigated the effects of moderate dehydration (~2.5% body weight) on muscle strength and endurance using percutaneous electrical stimulation to quantify central and peripheral fatigue, and isolate the combined effects of exercise-heat stress and dehydration, vs. the effect of dehydration alone. Force production and voluntary activation were calculated in 10 males during 1 brief [...]

This study examined whether drinking of water with breakfast affects the feelings of satiety and hunger, and how long after the meal this effect is maintained. Eight healthy, normal-weight women had three breakfasts with two extra glasses (4 dl) of water and three similar breakfasts without water. The breakfasts were served on three successive mornings during a 2 week period. The subjects filled in forms with visual analogue [...]

BACKGROUND: Secondary school students often do not drink sufficient quantities of water during the school day to prevent dehydration, promote learning and good health. The study aimed to measure the effect of health promotion and the free provision of cooled filtered water on the consumption of water and soft drinks. It also aimed to explore students' views of drinking water provision. METHODS: A study was conducted with three secondary schools in North Tyne side. [...]
