Case ReportsLocalized Langerhans cell histiocytosis of bone: treatment and follow- up in children.
We report a case of Langerhans cell histiocytosis (LCH) involving the right scapula in a 4-year-old child. Because of progressive shoulder pain and immobility methylprednisolone was injected directly into the lesion under computed tomography (CT) guidance. ⋯ We consider intralesional corticoid instillation a safe method when performed under CT guidance. For initial evaluation and follow-up, MRI and US yielded reliable results in comparison to plain films and CT, thus helping to reduce the radiation dosage in children.

Commentary: sonography in the evaluation of children following blunt trauma: is it to be or not to be?
Over the past decade CT scanning has become generally accepted in North America as the diagnostic modality of choice for the evaluation of abdominal injury in children following blunt trauma [1-5]. Recently, there has been increasing interest in the use of sonography as the primary screening examination in this area. Initial studies utilizing sonography in the evaluation of trauma patients focused primarily on identifying hemoperitoneum in adults [6-8]. ⋯ Their work in this area should be applauded. However, whether widespread application of this modality can be successful remains uncertain. In the space below a critical evaluation of sonography and CT in the assessment of injured children is presented.

Comparative StudyReliability of ultrasound in the early diagnosis of developmental dysplasia of the hip.
The purpose of this study was to determine inter- and intra-observer agreement in assessing hip morphology and stability by ultrasound. Three groups of infants, of 206, 74 and 78 newborns respectively, were examined. Morphology was classified into four categories (normal, immature, minor dysplastic and major dysplastic) according to subjective assessment, objective measurement (of the acetabular inclination angle alpha) or a combination of the two. ⋯ The authors concluded that a high degree of inter- and intra-observer agreement in classifying hip morphology may be obtained for the reading of recorded ultrasound scans. Inter- and intra-observer agreement in producing the scans is poorer than for reading. To obtain a high degree of inter-observer agreement in assessing hip morphology and stability in the newborn, substantial training, attention to details in the technique, and evaluation of results are necessary.
