Malignant fibrous histiocytoma is a rare malignant tumor of histiocytic origin, arising from either bone, or soft tissue. Six cases of malignant fibrous histiocytoma are presented with emphasis on radiographic features. Five cases are of primary bone origin and one of soft tissue. Ill-defined osteolytic bone destruction with no sclerosis and with no periosteal reaction is the principal radiologic feature of the malignant fibrous histiocytoma of bone. Therefore, malignant fibrous histiocytoma should be considered in differential diagnosis of primary intraosseous or extraosseous malignancies.

In shape and dimensions, the tibial plateaus are asymmetric with the larger medial tibial plateau and both have a posterior inclination with respect to the shaft of the tibia. Maximizing tibial coverage is an impotant consideration in total knee arthroplasty to provide stahility and load transfer and to improve long-term survival rate of the implants. Most tihial tray designs are symmetric, but several asymmetric designs are available. We evaluated the proximal tibial resection surface during total knee aithroplasty to delineate the tibial plateaus in korean. After tihial bone cut during 100 TKA procedures, the outline of tibial resection suiface was traced and rotational axis of true tibial component was marked intraoperatively. A line was drawn at the maximal anteroposterior (AP) diameter of lateral tibial condyle with parallel to rotational axis of component, and then a transverse axis was drawn at the midpoint of maximal AP diameter of 1ateral tibial condyle. Anteroposterior 10, 20, 30., 40% and midpoint from the media1 and lateral peripheries were calculated manually. The average AP medial 10, 20, 30 and 40% dimensions were 34.7, 43.8, 48.0 and 43.2mm, respectively. The average AP lateral 10, 20, 30 and 40% dimensions were 30.2, 38.4, 42.0 and 40.9mm, respectively. The ratio of medial/lateral AP dimensions 10, 20, 30 and 40% from periphery were 116.9, 114.7, 114.5 and 106.4%, respectively. From these data, we know the asymmetry of the proxirnal tibia1 plateaus in korean. We hope that rnore data will be ohtained in multicenter studies and it will help us to select tibia1 tray and to design the tibial component in korean. But, more accurate standard measures will he need to minimize an error of measurements.

Schizencephaly, first described by Yakovlev and Wadsworth in 1946, is a rare congenital anomaly characterized by gray matter-lined clefts that extend through the entire cerebral hemisphere, from the ependymal lining of the lateral ventricle to the subarachnoid space. Clinically, patients with schizencephaly present motor dysfunction such as hemiparesis, seizures, and variable developmental delay. Absence of septum pellucidum, gray matter heterotopia, polymicrogyria, and hypoplasia of optic nerves were also frequently found to be associated with schizencephaly. We experienced a case of open-lip schizencephaly in a one-day-old male infant with wide, tense fontanel, which was confirmed by MRI.

Postpartum hemorrhage is an important cause of maternal mortality and morbidity. Especially uterine atony is the most common cause of postpartum hemorrhage. Conventional method to control postpartum uterine atonic bleeding is based on the use of oxytocin and ergot preparations. Prostaglandin F2alpha analogue such as carboprost can be used to promote contraction when these agents fail to produce uterine contraction. Prostaglandin E1 analogue, misoprostol has uterotonic effect by oral or vaginal administration. They are used to induce labor and first or mid trimester abortion. In postpartum uterine atonic bleeding, misoprostols cannot be used via oral or vaginal route. Recently we have experienced that postpartum uterine atonic bleedings unresponsive to conventional methods were controlled by rectal misoprostols. So we report these cases with a brief review of literatures.
