abstract a 26 -year- old woman presented with rhabdomyolysis secondary to severe hypokalemia. hypertension and metabolic alkalosis could lead to the suspicion of primary aldosteronism, which was confirmed by a decreased plasma rennin, elevated plasma aldosterone levels and high aldosterone/rennin ratio additionally. additionally adrenal computed tomography showed an adrenal tumour. blood pressu...

Hyponatremia is the most common electrolyte disorder in hospitalized patients. Many studies documented that it was related to increased morbidity and mortality in patients with congestive heart failure, liver cirrhosis, and neurologic diseases. Although knowledge of hyponatremia has been cumulated, the optimal management of hyponatremia remains incompletely established in clinical practice beca...

Hospital Physician January 2009 23 Hyponatremia represents an abnormal ratio of total body sodium to water and is commonly defined as a plasma sodium concentration less than 135 mEq/L (1 mEq/L = 1 mmol/L).1–7 Hyponatremia is the most common electrolyte abnormality in hospitalized patients, with mild hyponatremia (plasma sodium < 135 mEq/L) present in approximately 15% to 22% of patients, modera...

Hyponatremia is the most common electrolyte balance disorder, especially in the elderly and polymedicated population. The authors report the case of an 83-year-old man with symptomatic severe hyponatremia due to Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) related to pantoprazole. Pantoprazole was discontinued and serum sodium levels reached normal values in two months. To t...

Hyponatremia complicates 1% of hospital admissions and can be associated with serious central nervous system effects. We report a case of a 38year-old woman with hyponatremia resulting in seizures and coma. Medications are one of many causes of hyponatremia. This case emphasizes the need to consider selective serotonin reuptake inhibitors (SSRIs) as a potential source of hyponatremia in all age...

Hyponatremia is a clinically relevant disorder. Ten to twenty per cent of patients in hospitals are affected by it. Hyponatremia is found to occur in almost every clinical department. Recently, vasopressin antagonists have been licensed to treat hyponatremia of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). They provide physicians with the first specific and effective the...

Dilutional hyponatremia is a commonly observed disorder in hospitalized patients. It represents an excess of water in relation to prevailing sodium stores and is most often associated with a high plasma level of arginine vasopressin, including that found in patients with the syndrome of inappropriate antidiuretic hormone secretion. Hyponatremia may be classified as either acute or chronic depen...

The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is not so frequent but it is a representative entity of hyponatremia. Although the clinical features were established by Bartter and Schwartz more than 30 years ago (1), a prototype of their diagnostic criteria has been applied so far. Hyponatremia is not a rare condition, especially in elderly persons. Nearly 1 to 5% of ho...

To the Editor, Multiple risk factors for osteoporotic fracture, inclu ding osteoporosis and falls, are widely known. It is also clear that osteoporotic fractures impose a significant morbidity and mortality in the elderly, with major mone tary costs associated. Recent studies suggest that chronic hyponatremia (serum [Na+] < 135mEq/L), albeit slight (serum [Na+] = 125-134 mEq/L), may be associat...
