25. Pulmonary metastatic calcification with respiratory insufficiency in patients on maintenance haemodialysis.
A uraemic patient undergoing chronic haemodialysis developed diffuse metastatic pulmonary calcification and died from acute respiratory insufficiency after renal transplantation. Thirteen similar cases previously published are reviewed, with emphasis on the clinical and anatomical features of such calcinosis. The pathogenesis of this calcification in patient

26. Nonsteroidal anti-inflammatory drugs. Proposed guidelines for monitoring toxicity.
The most common toxicities of nonsteroidal anti-inflammatory drugs (NSAIDs) are gastropathy, renal dysfunction, and liver function abnormalities. We outline an approach to monitoring patients on long-term NSAID therapy, focusing on the early detection of complications. Gastropathy caused by NSAID use is more common in elderly patients or those with a history

27. Nephropathy induced by contrast media: pathogenesis, risk factors and preventive strategies
WITH THE INCREASING USE OF CONTRAST MEDIA in diagnostic and interventional procedures, nephropathy induced by contrast media has become the third leading cause of hospital-acquired acute renal failure. It is also associated with a significant risk of morbidity and death. The current understanding of the pathogenesis indicates that contrast-medium nephropathy

28. Gentamicin pharmacokinetic changes in induced acute canine nephrotoxic glomerulonephritis.
Most clinical schemes used to adjust gentamicin dosage regimens in renal insufficiency assume that the volume of distribution remains constant. The purpose of this investigation was to determine the pharmacokinetic parameters of gentamicin (two-compartment open model) before and at two points during the acute phase of experimentally induced nephrotoxic (inje

29. Renal ammonia and glutamine metabolism during liver insufficiency-induced hyperammonemia in the rat.
Renal glutamine uptake and subsequent urinary ammonia excretion could be an important alternative pathway of ammonia disposal from the body during liver failure (diminished urea synthesis), but this pathway has received little attention. Therefore, we investigated renal glutamine and ammonia metabolism in midly hyperammonemic, portacaval shunted rats and sev

30. Middle aortic syndrome. Effectiveness and durability of complex arterial revascularization techniques.
Middle aortic syndrome typically occurs as severe hypertension in young patients who have weak or absent femoral pulses and an abdominal bruit. It results from a diffuse narrowing of the distal thoracic and abdominal aorta, commonly involving the visceral and renal arteries. The clinical presentation, angiographic assessment, and surgical outcome of 10 patie

31. Identification of Ehrlichia chaffeensis morulae in cerebrospinal fluid mononuclear cells.
We report a case of ehrlichiosis in a 72-year-old man who developed extreme lethargy, acute renal failure requiring hemodialysis, and respiratory insufficiency requiring intubation. Lumbar puncture performed on the second day of hospitalization revealed significant cellular pleocytosis. Ehrlichia morulae were tentatively identified in mononuclear cells in ro

32. Pharmacological Studies with 5-Fluorocytosine
A cylinder plate bioassay for 5-fluorocytosine (5-FC) is described which permits determination of 5-FC concentrations in biological fluids in the presence of amphotericin B. Using this assay, we determined serum concentrations in 12 patients after a single dose of drug and in 8 patients receiving daily 5-FC at 6-hr intervals (4 to 120 days). Drug was detecta

33. Platelet factor 3 in normal subjects and patients with renal failure
Two tests were used to differentiate abnormalities in release of platelet factor 3 (PF3) from quantitative deficiencies of this factor in normal subjects and in patients with renal failure. The first test was an assay which determined availability of PF3 (PF3-A time) and involved the use of a mixture of patient's platelet-rich plasma (PRP) and normal platele

34. Anomalous Right Subclavian Artery Aneurysms: Report of 3 Cases, with a Review of the Literature
During the past 2 years, 3 anomalous right subclavian artery aneurysms have been encountered at the St. Louis Heart Institute. The 1st patient, a 72-year-old woman, was found to have an asymptomatic 5-cm-diameter anomalous right subclavian artery aneurysm after surgery for suspected rupture of an abdominal aortic aneurysm. Resection was not attempted because

35. Pharmacology and Efficacy of Netilmicin
Twenty-six patients, 20 to 77 years of age, were treated with netilmicin, mean dose 2 mg/kg every 8 h intramuscularly or in a 20-min intravenous infusion. The mean serum half-lives in patients with creatinine clearances of ≥90 ml/min and 60 to 90 ml/min were 3.2 and 3.4 h, respectively. In patients with serum creatinines of ≤1.4 mg/100 ml and creatinine

36. Effect of antihypertensive treatment on kidney function in diabetic nephropathy.
The effect of long term, aggressive antihypertensive treatment on kidney function in diabetic nephropathy was studied prospectively in 11 insulin dependent diabetics (mean age 30). During the mean pretreatment period of 32 (range 23-66) months the glomerular filtration rate decreased significantly and albuminuria and the arterial blood pressure increased sig
