Two cases of neurofibrossrcoma involving cutaneous tissues of the patients with multiple neurofibromatosis were presented. One case, 49-year-old man, showed highly malignant histopathological feature with lethal outcome and the other case, 56-year-old man, showed less malignant histopathology with good recovery from local excision.

Authors tried methyl-prednisolone pulse therapy in 12 cases of severe cases of alopecia areats(eight cases of alopecia totalis, two cases of alopecia universalis, and two cases of alopecia subtotalis) by the assumption that administration of corticosteroid by pulse method minimize its side effects and maximize its therapeutic effect. Authors followed the courses of therapeutic result of the 12 cases for at least one year after finishing t.he treatment. The results were as follows : 1. The overall evaluation of the treatment showed four cases with excellent response, one case with good response, one case with disappointed response and six cases with no response. 2. The responses of the therapy appeared to be dependent on the duration of the alopecia areata ; the better the response is, the shorter the duration of the alopecia is. Most cases shorter than 6 months duration of alopecia showed excellent response. 3. Side effects of the treatment were as follows ; facial flushing(12/12), intermenstrual spotting(4/7), weight gain(4/12), moon face(3/12), acneiform eruption(1/12), exacerbation of hypertension (1/12). Those side effects did not keep any patient from the planned treatment.

Parosteal lipoma is a rare and generally asymptomatic benign tumor of mature adipose tissue that is located in direct apposition to the external surface of the bone. These tumors are occasionally associated with reactive changes in the underlying bone. The reactive bone formation is generally restricted to the base of the tumor, that is, near the periosteum. We recently experienced a case of parosteal lipoma in the proximal femur, which displayed exuberant bone and cartilage formation, and this led us to a misdiagnosis of chondroblastic osteosarcoma on the initial biopsy. We report here on this case with a special emphasis on making the differential diagnosis from osteosarcoma.

Purpose: To analyze the causes and to prevent dislocations of the hip joint that occur in patients who underwent revisions of total hip arthroplasties by changing only the polyethylene liners and femoral heads, subsequent to primary total hip arthroplasties. Materials and Methods: We evaluated 28 patients who underwent acetabular component revisions of total hip arthroplasties subsequent to primary total hip arthroplasties. The average age of the patients was 55 years old and all 28 patients had operations through the posterolateral approach. In 17 of the cases, the acetabular cups, polyethylene liners, and femoral heads were changed; in 10 cases, just the polyethylene liners and femoral heads were changed; and in 1 case, only the polyethylene liner was changed. Results: We observed 7 cases of hip dislocations that occurred among a total of 28 cases after revisions of total hip arthroplasties. In all 7 cases, the polyethylene liners and femoral heads were changed, but not the acetabular cups. In additional, in all 7 cases of dislocation, the patients were non-compliant and started weight-bearing prematurely after revisions of the total hip arthroplasties Conclusion: We observed new dislocations in the 7 cases in which the polyethylene liners and femoral heads were changed. The main reasons were inadequate soft tissue tension and hip joint laxity. Therefore, it is necessary to increase the neck length, use elevated rim polyethylene liners, readjust the acetabular cups to their optimal positions, and apply hip abduction braces to patients early after revision of total hip arthroplasties in order to lessen the danger of dislocations.

To determine the perinatal mortality and morbidity of fetuses with absent end-diastolic velocities (AEDV) of the umbilical artery in severe pre-eclampsia and eclampsia, the outcome of 5 fetuses with AEDV was compared with that of 35 fetuses with positive end-diastolic velocities (PEDV). The study population comprised 38 cases of severe pre-eclampsia and 2 cases of eclampsia with structurally normal singletons, who had had umbilical artery Doppler velocimetry weekly from admission to delivery. The Doppler velocimetry result was not used for the clinical management. Perinatal death and neonatal morbidity from both groups were further examined in gestational age category to control the influence of preterm births. The incidence of AEDV of the umbilical artery Doppler velocimetry in severe pre-eclampsia and eclampsia was 12.5% (5/40). The AEDV group had a significantly higher incidence than the PEDV group in terms of ceasarean section due to fetal distress (60% : 17%), Apgar score < 7 at 5 minutes (60% : 14%), perinatal death (25% : 0%) and assisted mechanical ventilation (67% : 9%) both at 32-36 weeks. Time intervals from the detection of AEDV to delivery of live neonates varied from the day to 15 days. In conclusion, AEDV in the umbilical artery might be of clinical value in routine surveillance of pregnancies complicated by severe pre-eclampsia and eclampsia, and predict hypoxic fetal condition which needs operative interventions before or during labor and mechanical ventilation after birth.
