Septic sacroiliitis due to Proteus mirabilis.
This case demonstrates the difficulty frequently encountered in making an early diagnosis of septic sacroiliitis. The proper use of appropriate laboratory tests and radiologic examinations can narrow the differential diagnosis significantly, with confirmation resting on culture results. Appropriate antibiotic therapy will depend on the organism isolated. When confronted by the typical clinical findings and supporting ancillary data of septic sacroiliitis, the physician should consider the possibility of an unusual organism such as Proteus mirabilis and should direct antibiotic therapy accordingly.
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.
