Disorders of fuel metabolism: medical complications associated with starvation, eating disorders, dietary fads, and supplements.

Disorders of fuel metabolism as they relate to abnormal fuel intake,abnormal fuel expenditure, and dietary supplements are the focus of this article. The emergency physician should be aware of the medical complications that can occur as a result of starvation states,eating disorders, fad diets, hypermetabolic states, and ergogenic aids. Knowledge and understanding of the complications associated with these disorders will facilitate the diagnosis and management of patients who present to the emergency department with any of the disorders reviewed.

It has been known for years that mixing household cleaning products can be hazardous. Nonetheless, from time to time, episodes of pneumonitis from such mixing occur. Although symptoms range from minor upper respiratory irritation to adult respiratory distress syndrome, deaths are very rare.

5-Methyltetrahydrofolate is reabsorbed and metabolized in isolated perfused rat kidney.

The renal regulation of folate excretion is an important component in maintaining the body burden of folate. The tubular processes for folate disposition have been examined by a variety of methods to elucidate the mechanism by which renal folate excretion is regulated. Accordingly, the isolated perfused rat kidney technique was evaluated by investigating the clearance and metabolic patterns of 5-methyltetrahydrofolate (5-CH3-H4PteGlu).
