Abstract

A simplified method is presented to estimate reference ranges from hospital laboratory data. It is based on a combination of graphical estimation of relative sizes of normal and abnormal populations and the "mode-center" concept in which the mode of the total population centers on the 50% cumulative frequency of the normal population. This method can be applied to determine reference ranges even though the data source contains abnormally high and/or low values. The reference ranges obtained for BUN and calcium from in-patient and out-patient sources by this method were found to be similar to those reported for "healthy" subjects.

Adequacy of hemodialysis.

Despite technical advances in the delivery of hemodialysis over the past decade, the mortality rate of hemodialysis-dependent, end-stage renal disease (ESRD) patients in the United States remains high. The increase in the number and severity of comorbid conditions of patients entering ESRD is a factor contributing to this high mortality. Nevertheless, there is increasing evidence that the dose of dialysis received by US patients is inadequate and that this plays a major role in the observed high mortality. In this review, we examine some of the parameters used to judge the adequacy of dialysis, as well as factors that can result in differences between prescribed and delivered dose of hemodialysis. Based on available evidence, we propose that for most patients the optimum dose of dialysis, above which further improvement of morbidity and mortality is doubtful, is represented by a delivered dose of dialysis equivalent to a Kt/V of 1.4 or greater, using biocompatible membranes. The prescription of this optimal dose of dialysis must be coupled with an ongoing effort to monitor delivery of the appropriate dose.

Ultrasonographic screening for renal abnormalities in three-year-old children.

We report the results of ultrasonographic screening to determine the prevalence of renal abnormalities in children. This study was conducted simultaneously with a regular health check using portable realtime ultrasound equipment, from July 1988 to June 1989. Of 2920 three-year-old children resident in Kurume City, 2351 (80.5%) were screened. Abnormalities were detected in 11 (0.47%) of these, involving six cases of pelvic dilatation, three cases of unilateral renal agenesis, and two cases of a unilaterally small kidney. However, the simultaneous urinalysis of these 11 children did not disclose these abnormalities. Our results indicate that ultrasonography is an efficient tool for screening for a silent renal abnormality.
