Nephrocalcinosis in prematures

Nephrocalcinosis is increased renal calcium content determined biochemically and confirmed radiologically. Serial follow up [biochemical and renal US] for all subjects included in this study [23 preterm and 69 control] was done including parents for those with positive family history of renal stones. Two cases out of 23 preterm developed nephrocalcinosis [8.7%]. Positive FH of renal stones was found among three out of the 23 preterm, two of them showed nephrocalcinosis by US. However, four out of 69 control term infants had positive FH of nephrolithiasis and none of them developed nephrocalcinosis. It was concluded that nephrocalcinosis developed with LBW preterm is significantly associated with positive FH of urolithiasis rather than other risk factors [TPN, Furosemide]. Such preterms, especially VLBW, should thoroughly followed with kidney functions, serial renal US and cautiously using furosemide for long period early in life and proper management of participants with renal stones to avoid premature deliveries and its complications

relation of mid-arm and chest circumferences to birth weight

Birth weight is a reliable and important indicator of the immediate and the later outcome of health care. It may be a problem in rural areas where home deliveries are prevalent and weight records are usually lacking. The aim of this work is to find out the correlation of mid-arm and chest circumferences [MAC and CC] to birth weight, which is a very simple and easy measurement. The results of 321 neonates, 180 term [> 37 ws] and 141 pre-term, [< 37 ws] showed a significant correlation between birth weight and MAC [0.8710] and with CC [0.8475] with no sex difference
