Different techniques of continuous renal replacement therapy (CRRT) might have different effects on azotemic control. Accordingly, we tested whether continuous veno-venous hemodiafiltration (CVVHDF) or continuous veno-venous hemofiltration (CVVH) would achieve better control of serum creatinine and plasma urea levels. ⋯ CRRT strategies based on different techniques might have a significantly different impact on azotemic control.

This report describes a 56-year-old man with a ruptured infected abdominal aortic aneurysm secondary to Salmonella bacteremia, initially presenting as acute pyelonephritis. Spike fever with severe back pain continued despite empiric antibiotic treatment at a local hospital. Hypotension with a sudden hemoglobin drop was observed on the second hospitalization day. ⋯ This case was successfully treated through prompt surgical intervention and aggressive protracted antibiotic therapy. The case presented herein raises concerns about the uncommon but life-threatening mycotic aneurysm presented initially as acute pyelonephritis. Early diagnosis and appropriate surgical and antibiotic treatment of the Salmonella mycotic aortic aneurysm is crucial for a satisfactory outcome.

High anion gap metabolic acidosis in suicide: don't forget metformin intoxication--two patients' experiences.
Lactic acidosis is a well-recognized side effect of metformin, especially in patients with renal failure. Only a few cases of deliberate self-poisoning with metformin have been described in the literature. We report two patients who took a large dose of metformin in an attempt to harm themselves and both of them presented with severe lactic acidosis. ⋯ After one session of hemodialysis, she recovered completely. In our experiences, metformin intoxication should be suspected when patients presented by wide anion gap metabolic acidosis after suicide attempt by taking drugs. Hemodialysis or continuous renal replacement should be initiated as soon as possible in addition to other supportive care.
