We report the case of a 46-year-old male with a known diagnosis of metastatic malignant melanoma who presented with hyponatraemia. The report details the challenges we faced in identifying the cause of his hyponatraemia and in attempting to reverse his electrolyte disturbance.As his clinical condition deteriorated the focus of our management needed to change; recognising that he was dying we im...

Caffeine is regarded as a diuretic despite evidence that hydration is not impaired with habitual ingestion. The purpose of this study was to determine whether a caffeinated sports drink impairs fluid delivery and hydration during exercise in warm, humid conditions (28.5 degrees C, 60% relative humidity). Sixteen cyclists completed 3 trials: placebo (P), carbohydrate-electrolyte (CE), and caffei...

Lack of a uniform definition is responsible for underrecognition of the prevalence of malnutrition and its impact on outcomes in children. A pediatric malnutrition definitions workgroup reviewed existing pediatric age group English-language literature from 1955 to 2011, for relevant references related to 5 domains of the definition of malnutrition that were a priori identified: anthropometric p...

Non-destructive analysis of degradation mechanisms can be very beneficial for the prognostics and health management (PHM) study of lithium-ion batteries. In this paper, a type of graphite/LiCoO2 battery was cycle aged at high ambient temperature, then 25 parameters of the multi-physics model were identified. Nine key parameters degraded with the cycle life, and they were treated as indicators o...

The recognition of the electrolyte disturbance in the sweat of patients with fibrocystic disease by Darling, diSant' Agnese, Perera and Andersen (1953) led Shwachman, Leubner and Catzel (1955) to devise a simplified method of obtaining sweat for biochemical assay. In this method the patient is placed in a plastic bag up to the neck and covered with a blanket, the sweat being collected in a weig...

OBJECTIVE To investigate the relationship between work and quality of life of doctors and nurses in pediatric intensive care units and neonatal. METHODS Cross-sectional study with 37 doctors and 20 nurses. The Job Content Questionnarie (JCQ) e Effort-Reward Imbalance (ERI), and World Health Organization Quality of Life (WHOQOL-100) were used. The correlation was estimated by Spearman correlat...

Potassium depletion in rats augments the specific renal lesions of phosphate loading. Since it has been shown that phosphate loading increases the specific cardiac lesions of potassium deficiency (12), it is concluded that the similar types of electrolyte imbalance (potassium depletion-phosphate load) act conversely in the two organs.

IN ELECTROLYTE imbalance the failure of the electrocardiogram to correlate with clinical and laboratory findings may result in both diagnostic and therapeutic dilemmas. Several authors 14 in particular have stressed the lack of conformity of electrocardiographic manifestations with the serum levels of potassium. This disparity has been attributed to the presence of electrocardiographic alterati...
