Gastrointestinal sarcoidosis: a case report

Gastrointestinal sarcoidosis commonly occurs subclinically, with clinical manifestations present in only 0.1 to 0.9% of patients with the disease. Gastric sarcoidosis particularly involves the antrum. Small bowel, liver and spleen involvement is seen in approximately 10% of patients with systemic sarcoidosis. We report a rare case of gastrointestinal sarcoidosis of the stomach and terminal ileum, affecting the liver and spleen without pulmonary involvement, who responded favorably to corticosteroid treatment

Profound hyperkalemia and the electrocardiogram. Lack of correlation: a case report

We report a case of severe hyperkalemia as a result of treatment with potassium sparing diuretics, digoxin and angiotensin receptor antagonist valsartan in the presence of renal insufficiency. Inspite of a maximal serum potassium concentration of 10.3 mmol/l, only non-specific ECG changes were found. The patient survived after an uneventful dialysis. Thus severe hyperkalemia may present without typical ECG changes, and values exceeding 10.3 mmol/l may not necessarily be fatal
