Signs and Symptoms of Magnesium Depletion Symptomatic magnesium depletion is often associated with multiple biochemical abnormalities such as hypokalemia, hypocalcemia, and metabolic alkalosis. As a result, it is often difficult to ascribe specific clinical manifestations solely to hypomagnesemia. In 1960, five patients were reported with symptoms considered to be typical of magnesium depletion...

We read with great interest the paper by Schilder and colleagues on citrate anticoagulation versus systemic heparinisation (CASH) [1] and its related commentary [2], but would like to comment on two important metabolic issues. First, in-circuit ionized calcium was not monitored in the CASH trial. Keeping postfilter ionized calcium within tight limits, however, results in more optimal anticoagul...

CASE PRESENTATION A 69-year-old man was admitted to hospital for the evaluation of refractory hypokalemia and metabolic alkalosis. The patient had a 1-year history of a stage pT4N0M1 non-small cell squamous lung carcinoma (NSCLC) that was managed by Pemetrexed (Alimta 500 mg/m every 21 days) for the last 6 months. The patient had a 45-pack/y history of smoking without history of alcohol abuse, ...

CALDER, W+ A., AND KNUT SCHMIDT-NELSEN. Punting and blood carbon dioxide in birds. Am. J* Physiol, 215(2): 4771482. 1968.-The respiration of resting and panting birds was studied in nine species representing a wide range of size, morphology, and habits. All these birds had similar values for arterial blood PCU~ and pH during normal resting respiration (28 mm C02, pH = 7.5). These values are muc...
