Comparison of the results of multistix®-SG and comber-9-Test®RL urine dipstick assay.: Dae Chul Kim, Kyung Dong Kim, Bo Chan Jung, Chung Sook Kim, Kil Ho Cho; Yeungnam Univ J Med. 1991;8(1):42-52. Published online June 30, 1991; DOI: https://doi.org/10.12701/yujm.1991.8.1.42

Abstract PDF: Two types of urine dipstick assays, Multistix-SG and Comber-9-Test RL, were compared for compatibility, accuracy, specificity and predictive values of a positive and negative test in 501 patients' urine and artificially prepared specimen. We found that the results of semiquantitative tests of Multistix-SG and Comber-9-Test RL performed were statistically similar in patients' specimen. The urinary leukocyte esterase tests of Comber-9-Test RL assays compared with urine sediment microscopy in regard to compatibility, sensitivity, specificity, and predictive values of a positive and negative test 83.7%, 48.1%, 90.3%, 47.4% and 90.1%, respectively. The urinary nitrite tests of Comber-9-Test RL assays compared with urine culture tests, in regard to compatibility, sensitivity, specificity, and predictive values of a positive and negative test were 90.3%, 19.4%, 84.7%, 53.8% and 94.1, respectively. For the urinary protein, the sulfosalicylic acid method was the most sensitive test for any kinds of protein, and Multistix-SG appeared more sensitive than Comber-9-Test RL for the albuminuria. For the urinary bilirubin and glucose, two dipstick assays were similar in their diagnostic efficiency. Finally in the urinary occult blood tests, Comber-9-Test RL assays was more sensitive than Multistix-SG.

Significance of Low Serum Urea Nitrogen Concentrations.: Chung Sook Kim, Kyung Dong Kim, Dae Chul Kim; Yeungnam Univ J Med. 1990;7(2):159-165. Published online December 31, 1990; DOI: https://doi.org/10.12701/yujm.1990.7.2.159

Abstract PDF: The prevalence of low serum urea nitrogen concentrations (<6 mg/dL) in our patient population was 3.8% (452 per 11,911 determinations), representing 372 individual cases. Of these, 323 of the patients' charts were located, reviewed, and classified into disease groups. Malignant tumor was found in 25.1% of the 323 patients, the remaining patients without malignant tumor had various clinical conditions; pregnancy (19.5%), infectious diseases (12.1%), trauma (10.2%), cerebrovascular accident (6.2%), hepatopathy (5.3%), and miscellaneous conditions (21.6%). The prevalence in female and young aged patients under 5 years was considered due to the lower reference range in these groups than in that of female adult groups, and moreover pregnancy in another superimposing factor in the former group. In regards to the causes of this condition, our study corresponded well to the textbook cited etiology of the low serum nitrogen concentration, although malnutrition and hepatopathy were inverted in their incidental order. We postulated, through the present study, that the low serum urea nitrogen concentration is not pathognomonic findings to suggest specific disease or conditions, but rather to reflect patient's general conditions such as hydration, nutrition, or administration of certain drugs.

Analysis of Surgical Blood Use in Operation at YUMC.: Chung Sook Kim, Kyung Dong Kim, Dae Chul Kim; Yeungnam Univ J Med. 1990;7(1):133-144. Published online June 30, 1990; DOI: https://doi.org/10.12701/yujm.1990.7.1.133

Abstract PDF: This study was performed to guide the effective utilization of blood and optimal blood ordering schedule for various elective surgeries, based on the analysis of 1,462 transfused surgical procedures and 5,933 blood units transfused during operation in the period of two years through January, 197 to December, 1988 at Yeungnam University Hospital. The frequency of transfusion, and mean transfused units were evaluated and recommended blood unit for each surgical procedure was proposed. We assure that the successful establishment of this guideline can lead to substantial monetary saving, reduced blood outdating, and a decreased blood bank workload with a more appropriate allocation of the technician's time and effort.
