US and MDCT diagnosis of a rare cause of haematuria in children: Posterior nutcracker syndrome.
Posterior nutcracker syndrome is caused by compression of the left renal vein between the abdominal aorta and the vertebral column. We present the case of a 14-year-old girl with vague left loin pain, mild haematuria and proteinuria. Diagnosis of this rare syndrome was achieved using color Doppler US and multidetector computed tomography (MDCT) angiography.

Pulmonary ultrasonography in the follow-up of respiratory distress syndrome on preterm newborns. Reduction of X-ray exposure.
Respiratory distress syndrome (RDS) is the most common cause of respiratory failure in preterm neonates, whose lungs are often immature. The diagnosis and follow-up are based on clinical and radiographic findings. Due to the problem of air artifacts, ultrasonography (US) is not used routinely in the diagnosis of lung diseases. However, when the alveolar air content decreases, as it does in RDS, characteristic patterns appear that can be observed during US lung examinations. The aim of this study was to determine whether the use of chest radiographs in neonates with RDS could be reduced by the routine use of chest US for follow-up examinations. ⋯ Chest ultrasound is a valid alternative for the follow-up of VLBW infants with RDS, which can decrease the need for chest X-rays and reduce patient exposure to ionizing radiation.
