The purpose of this retrospective study was to compare the morphologic change of the posterior cruciate ligament (PCL) in the anterior cruciate ligament (ACL) tear group and control group by the quantitative analysis. The study groups of patients were; acute ACL tear group (21 patients), chronic ACL tear group (31 patients), and meniscus tear group (20 patients) that undertaken partial meniscectomy. To express curved shape of the PCL quantitatively, the authors made a line (basal line) between the femoral attachment and tib- ial attachment of the PCL and decided the point (apex) that was located most far away from the base line. And the authors made a line (line 1) between the femoral attachment and the apex of the PCL, another line (line 2) between the tibial attachment and the apex of the PCL, and quartered the base line; first quartile, Hl, second quartile, H2, and third quartile, H3. The authors measured the each angle between basal line and line 1 (angle a), between basal line and line 2 (angle b), each height of the PCL at each quartile (Hl, H2, H3) and at the apex of the PCL on the basal line (H4). Three groups were compared and examined which factor was able to decide whether the ACL was ruptured or nnt. Angle a was significantly higher in chronic ACL tear group than acute ACL tear group and meniscus tear group. In conclusion, the PCL of sigmoid or curled up shape is a more constant finding of chronic ACI tear than acute ACL tear.

Introduction: This study examined the factors related to the amount of blood loss and transfusion after primary total hip arthroplasty. Materials and methods: Sixty THRA patients, who had records of perioperative complete blood counts and transfusion, were enrolled in this study. Age, gender, diagnosis, use of cement, size of an incision, operative time, intraoperative crack, estimated blood loss, use of suction drain and the amount drained were used as possible variables. Results: The decrease in the serum hemoglobin level immediately after and 1 day after surgery was 3.18 and 3.90g/dL respectively. An average of 2.30 units were transfused in 78.3% of cases. The preoperative serum hemoglobin level, the use of a suction drain and the amount drained was related to the total amount of transfusion. Adverse transfusion reactions were found to be associated with the amount of transfusion Discussion: The reduction in the hemoglobin level and total amount of blood transfused showed no relationship with the variances associated with the surgical techniques. The total amount of blood transfused was significantly lower in the groups that had no suction drain. Therefore, a reduction in the volume of intraoperative transfusion and avoiding use of a suction drain can reduce the total amount of blood needed and reduce the adverse reactions of the transfusion.

OBJECTIVE: To report the pregnancy which was made by in vitro fertilization using recombinant follicle stimulating hormone and gonadotropin releasing hormone antagonist. MATERIAL AND METHOD: Case report. RESULTS: Six oocytes were retrieved and all were fertilized by intracytoplasmic sperm injection. Six embryos were transferred and the pregnancy was confirmed. CONCLUSION: It is envisaged that the availability of recombinant gonadotropins and gonadotropin releasing hormone antagonists will ultimately lead to shorter, cheaper and safer treatments, using reduced dosages.

Yonsei University College of Medicine, Seoul, Korea Maffucci's syndrome is characterized by dysccondroplasia with hemangiomata. Since Angelo Maffucci (1881) first described this entity, 105 cases and some more were reported in the literature till 1976. We recently observed a patient suffering from this disorder. The patient is 21 year-old girl, who has multiple hemangiomes on her right foot, right buttock, left wrist and enchondromas on both proximal phalanx, distal phalanx of both great toes and proximal, middle phalanx of right second toe. The disease started at age of 11 and these lesions grew rapidly last 3 years. The diagnosis was based on clinical, radiological and histological findings. Because of its rarity, we report it with brief review of literature.

Thymic cyst is relatively rare tumor which usually occurs in the neck or mediastinum. Cervical thymic cyst is usually situated laterally and deep to the anterior border of the sternocleidomastoid muscle, simulating a branchial cyst. Thymic cyst of the mediastinum is usually detected incidentally and differential diagnoses include cystic degeneration of thymoma, and cystic teratoma. Two case of a cervical and a mediastinal thymic cysts were reported. The one was a cervical thymic cyst developed slowly growing mass in a 53-year-old male a for 10 years. The cyst was unilocular and measures 5.4x2.9x2.8 cm with columnar or squamous cell linings. The other is a mediastinal thymic cyst developed in a 37-year-old female with chest discomfort for 7 months. The cyst was uniocular and measures 2.8x2.2x2.0 cm. The epithelial lining of the cyst was largely desquamated and covered by macrophages with cholesterol granuloma. Involutional thymic stissue in their walls were noted in both cysts. In both cases presence of thymic tissue in the wall of the cyst thought to be the most important diagnostic feature.
