Review Case ReportsIntracranial involvement in extramedullary hematopoiesis: case report and review of the literature.
Intracranial involvement in extramedullary hematopoiesis (EMH) is rare, but it should be suspected in patients with myelofibrosis presenting with chronic severe headache. We present a 9-year-old girl with known myelofibrosis whose headaches were unresponsive to routine treatment. ⋯ CT examinations of the chest and abdomen had demonstrated bilateral thoracic paraspinal masses caused by EMH, suggesting the possibility that the intracranial involvement might also be related to EMH. The diagnosis was confirmed by sulfur colloid isotope scan.

Colour Doppler ultrasonography replacing surgical exploration for acute scrotum: myth or reality?
Traditionally, every patient with an acute scrotum needed surgical exploration for definitive exclusion of testicular torsion. ⋯ US has proven to decrease the number of emergency scrotal explorations, length of hospital stay and hence reduce the cost of management of acute scrotum.

Comparative StudyCT can reduce hospitalization for observation in children with suspected appendicitis.
There are no clinical or laboratory tests that can eliminate the possibility of appendicitis in a child with abdominal pain that suggests the diagnosis. The standard of care is to admit these children to the hospital for observation. More than twice as many children hospitalized for abdominal pain suggesting appendicitis are subsequently sent home after observation compared to those who undergo appendectomy. ⋯ Our data suggest that when the appendix can be visualized, CTRC can accurately identify a normal appendix and reduce the number of children hospitalized for observation for possible appendicitis.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialComparison of gadobenate dimeglumine (Gd-BOPTA) with gadopentetate dimeglumine (Gd-DTPA) for enhanced MR imaging of brain and spine tumours in children.
Gadobenate dimeglumine (Gd-BOPTA) demonstrates superior enhancement of brain tumours in adult patients than Gd-DTPA. ⋯ At an equivalent dose Gd-BOPTA is significantly better than Gd-DTPA for visualization of enhancing CNS tumours in paediatric patients.

Normal values of the sagittal diameter of the lumbar spine (vertebral body and dural sac) in children measured by MRI.
The definition of normal values is a prerequisite for the reliable evaluation of abnormality in the lumbar spine, such as spinal canal stenosis or dural ectasia in patients with Marfan syndrome. Values for vertebral body diameter (VBD) and dural sac diameter (DSD) for the lumbar spine have been published in adults. In children, normal values have been established using conventional radiography or myelography, but not by MRI. ⋯ MRI is a reliable method demonstrating the natural shape of the lumbosacral spine and its absolute values. These normal values compare well with those established by conventional radiological techniques. Our data may serve as a reference for defining dural ectasia in children with Marfan syndrome.
