Brief Summary:
The primary objective was to determine whether caffeine therapy is associated with decreases bone mineral content using dual energy x-ray absorptiometry. Secondary objectives were to determine whether caffeine therapy is associated with increased incidence of nephrocalcinosis or bone fracture.

Group/Cohort Intervention/treatment
caffeine group
22 preterm infants received caffeine (starting from day 2 of life and received for more than 7 days) for apnea prophylaxis or treatment according to protocol of Ain Shams University neonatal intensive care unit [apnea prophylaxis for preterm ≤32 weeks gestation and apnea treatment for those 33 or 34 weeks gestation]. Dual Energy X-ray Absorptiometry was done 5th-6th week post-natal age
Diagnostic Test: Dual Energy X-ray Absorptiometry
Dual Energy X-ray Absorptiometry done for both studied groups

control group
20 preterm infants for whom caffeine was not given, either it was not indicated, not available or parents refused its use.Dual Energy X-ray Absorptiometry was done 5th-6th week post-natal age
Diagnostic Test: Dual Energy X-ray Absorptiometry
Dual Energy X-ray Absorptiometry done for both studied groups

Primary Outcome Measures :
  1. effect of caffeine therapy on bone mineral content using Dual Energy X-ray Absorptiometry [ Time Frame: 5-6 weeks ]
    Whole Body Scanner, Pencil beam, regions: antro-posterior Spine, Lateral, Hip, Forearm/ Hand, Ortho Femur Speed: Up To 76mm Per Sec., Scan Times (min): antro-posterior Spine-2, Lateral-12, Hip-4, Forearm-1, Femur-4 Pentium II Computer System, Windows O/S, Lunar Software 15" Hi-Resolution Monitor, Auto Centering Laser Guide, Data Analysis: Auto Analysis Software, Smart Scan, Auto Position. Weight and length were measured and recorded. During the scan an infant was placed on the scanning table with the head at the marked start line, assuring that the position was the same for all subjects. The study was carried out with the infants sleeping without sedation. The infants were placed supine and were restrained with a cotton blanket. To induce sleep, infants were fed a few minutes prior to the study. When image quality was poor due to movement of the infant or to other causes the measurement at that time point was not included for analysis.
