A case of benign regressing histiocytosis of the liver is reported. The patient, an adult male, presented with fever and diarrhoea and on abdominal echography multiple nodules were present in the liver. Histologically and immunohistochemically the lesions had features of Langerhans' cell histiocytosis. The nodules regressed within four months, without therapy, and the patient is free of disease 29 months after presentation.

In this retrospective study, children with cerebral palsy underwent a unilateral femoral derotation osteotomy and had a preoperative (PO), short-term postoperative (1–3 years), and a long-term postoperative (≥5 years) gait analysis. Patients were subdivided into groups by the PO pelvic presentation and Gross Motor Function Classification System level. In children with PO pelvic external rotation, femoral derotation osteotomy decreased the hip internal rotation and decreased the pelvic external rotation. These results could influence surgical planning to achieve long-term pelvic asymmetry.
