Clinical Trial
Quantitation of proteinuria by the use of protein-to-creatinine ratios in single urine samples.
Measurements of protein-to-creatinine ratios in single-voided urine samples were compared with 24-hour urinary protein excretions for quantitation of proteinuria in inpatients and outpatients. Patients included those representing a broad spectrum of renal diseases, a wide range of proteinuria, and various degrees of reduction in glomerular filtration rate. Protein-to-creatinine ratios in single-voided urine samples correlated well with measurements of 24-hour urinary protein. This simple single-voided test is reliable and useful in the screening, assessment, and follow-up of proteinuria and avoids the problems associated with 24-hour urine collection.

To identify patients likely to be admitted to a critical care unit as well as those at high risk of deterioration, we studied all patients admitted to the medical service. Cardiac patients had a high likelihood of unit admission even if they were rated as not ill and stable, whereas ill and unstable noncardiac patients went to the floor. ⋯ If the goal is to admit patients at highest risk, the optimal strategy is to admit unstable, severely ill, and moribund patients in both the cardiac and noncardiac groups. By doing this, it is possible to decrease unit admission of patients likely to do well, increase the admission of patients likely to do poorly, while decreasing the number of patients admitted.

While mild to moderate hepatic dysfunction is commonly encountered in infectious mononucleosis induced by Epstein-Barr virus (EBV), clinical jaundice with high bilirubin levels (greater than or equal to 6.0 mg/dL [greater than or equal to 103 mumol/L] is only occasionally encountered. In this study, seven patients with primary EBV infections had peak bilirubin levels of 10.2 to 23.0 mg/dL (174 to 393 mumol/L) and, for the most part, presented initial diagnostic problems. ⋯ The laboratory data suggested that a combination of hemolysis and viral-induced cholestasis was responsible for the intense hyperbilirubinemia in at least five patients. Physicians should be aware that marked hyperbilirubinemia can occur with EBV-induced infectious mononucleosis and, thereby, obviate the need for costly diagnostic laboratory tests and, occasionally, invasive procedures.
