Water metabolism disturbances at different stages of primary thyroid failure.
The aim of the present study was to study salt and water metabolism in thyroid deficiency. We performed an oral water loading test (OWL) and a hypertonic 5% saline infusion test (HSI) in 16 patients with overt primary hypothyroidism before replacement treatment (PRE group) and after, in eight patients with subclinical hypothyroidism (SUB group) and [...]
THE RELATIONSHIP BETWEEN DEHYDRATION AND PAROTID SALIVARY GLAND FUNCTION IN YOUNG AND OLDER HEALTHY ADULTS
BACKGROUND: Saliva is essential for the maintenance of oral health. The primary constituent of saliva is water and, traditionally, decreased body water homeostasis has been linked with salivary dysfunction. This is consistent with the greater prevalence of dehydration and salivary gland dysfunction among the elderly. However, this association between dehydration and salivary dysfunction has never [...]
EVAPORATION RATE AND SKIN BLOOD FLOW IN FULL TERM INFANTS NURSED IN A WARM ENVIRONMENT BEFORE AND AFTER FEEDING COLD WATER.
Earlier results have shown that some infants born by elective Caesarean section start to sweat in a warm environment while others do not, and that sweating can be inhibited by feeding cold glucose. To determine whether these earlier observations, indicating a difference in postnatal temperature adaptation, could be reproduced in vaginally born infants, we measured [...]
EDEMA IN PREGNANCY.
During normal pregnancy total body water increases by 6 to 8 liters, 4 to 6 liters of which are extracellular, of which at least 2 to 3 liters are interstitial. At some stage in pregnancy 8 out of 10 women have demonstrable clinical edema. There is also cumulative retention of about 950 mmol of sodium [...]
EFFECT OF WATER DEPRIVATION ON COGNITIVE-MOTOR PERFORMANCE IN HEALTHY MEN AND WOMEN.
Whether mental performance is affected by slowly progressive moderate dehydration induced by water deprivation has not been examined previously. Therefore, objective and subjective cognitive-motor function was examined in 16 volunteers (8 females, 8 males, mean age: 26 yr) twice, once after 24 h of water deprivation and once during normal water intake (randomized cross-over design; [...]

BODY COMPOSITION IN PREGNANCY.
Concern over the influence of pregnancy-related alterations in hydration has prompted questions regarding the accuracy of using standard methods of determining body composition. We sought to investigate whether differences exist between body composition determined at 30 weeks and 39 weeks of gestation and postpartum, when measured by both bioelectrical impedance and hydrostatic weighing. This preliminary [...]
