So, random urine calcium to creatinine ratio (Ca/Cr ratio) has been developed. But as the ratio varies worldwide, reference values of the parameter in paediatric population are not developed. To determine reference value, the present study was conducted in healthy paediatric population in Burdwan district, West Bengal. This study was performed on 693 healthy paediatric subjects, aged between 3 months to 18 years and divided into five groups. Early morning non-fasting urine samples from all study groups were analyzed for Ca/Cr ratio. A negative correlation was observed between age and urinary Ca/Cr ratio, but there was no significant difference of urinary Ca/Cr ratio between two sexes. Considering 97.5th percentile of the underlying distribution of values as the upper limit of reference range, upper reference values of urinary Ca/Cr ratio for age groups展开更多

There were 13 male and 2 female patients. Theyhad no endocrine disturbances or other bone diseases. The ratio ofhydroxyproline/creatinine (HP/Cr) in these cases increased gradually within 20-30 daysafter fracture and then reached the peak value which was about 3-4 times of normal, thepeak value maintained for a long time. If the trauma was mild or the patient was young,the peak began to decline on the 60th day after fracture. While in those severe cases withprolonged confinement to bed, the peak only began to come down about 110th dayafter fracture. The ratio of HP/Cr decreased rapidly from the peak at first, then pursueda slow course. Generally, the ratio of HP/Cr returned to normal on the 240th to 310thday. Bone union began at a time when peak value started to decline, and with completionof the remodelling process, the HP/Cr value returned to normal.展开更多
