Various anatomical defects have been described in the surviving co-twin who had stillborn, macerated monozygotic co-twin with disseminated intravascular coagulation. The suggested mechanism was the transfer of emboli or thromboplastic materials of dead fetus to co-twin through placental vascular anastomoses. Multicystic encephalomalacia is the condition defined anatomically by the presence of multiple cavities in the great part of both cerebral hemispheres. The most common pathogenesis is circulatory disturbance caused by neonatal asphyxia during the perinatal period. We experienced two cases of monozygotic twin with deceased co-twin at 26 weeks, 33 weeks of gestation and confirmed the diffuse multicystic encephalomalacia by cranial ultrasonography and MRI in a surviving co-twin. Only one patient has been followed who showed spastic cerebral palsy and severe mental retardation. We report two cases of multicystic encephalomalacia in a surviring co-twin with a intrauterine fetal death and its related literatures.

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.

Twin reversed arterial perfusion (TRAP) sequence is a rare specific anomaly of twin gestation with fused placenta and umbilical anastomosis. This syndrome occurs once in about 34,600 births and reported first by Beneditti in 1533. We report on prenatal diagnosis of a case of TRAP sequence with color Doppler sonography, this case is presented with a brief review of the literature.

Seidel nail provides more advantages for treatment of humeral shaft fracture than other treatment modalities. It enables patients to get high bone union rate, makes surgical technigne less invasive, and allows early mobilization mobilization so that the patients is subjected to more comfortable treatment. But, Seidel nail is apt to injure the rotator cuff and has relatively weak holding power of distal fragment of fracture so that it may result in distraction and rotatory instability, and make nonunion and impaired shoulder function. Thus, in order to the functional and radiological results, complications and technical problems, we evaluated the efficacy of Seidel nail in treatment of 20 cases of hurneral shaft fractures from March l994 to March 1996, retrospectively. The results were as follows. 1. 18 cases(90%) achieved radiological union. 2. The time of union was 12.5 weeks in average. 3. 17 cases achieved satisfactory results according to Neers functional score. 4. The complications included proximal protrusion of nail from the entry site(10%), fracture of greater tuberosity of proximal humerus(5%), loosening of distal spreading screw(10%), and nonunion( l 0%). In conclusion, Seidel nailing is one of good treatment modalities for humeral shaft fracture, but skillful operative technique is needed to obtain the satisfactory functional result. And also, it is necessory to modify the distal locking system of Seidel nail to reinforce the rotational stahility of the fracture site.

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.

Drug-induced thrombocytopenia and purpura have boon developed by many various agents. Rifampin and Pyrazinamide have been known as bactericidal antituberculous drugs, but, the above side effects have been a problem. Especially, hematologic side effects art fatal to patients occasionally. Rifampin-induced thrombocytopenia and purpura have been well known, also, pyrazinamide-induced thrombocytopenia have been reported. A new quilonone agent Ciprofloxacin, has been commonly used in clinics now, but it's side effects are not known well. So, we report a case of a 23-year-old female with thrombocytopenia and purpura after taking Rifampin, Pyrazinamide, and Ciprofloxacin as antituberculous agents.

The origin of osteoclast-like giant cell tumor (OGCT) of the salivary gland has been debated because the prototypic cells of osteoclast-like cells and mononuclear stromal cells are largely unexplained in this gland. Bone marrow-derived CD14+ and CD45+ monocyte-derived multipotential cells (CD14+/CD45+ MOMC) may be one of the possible origins of OGCTs of salivary glands, which have never been explored in salivary OGCTs. We present a case of OGCT accompanied with carcinoma ex pleomorphic adenoma in the parotid gland of a 67-year-old Korean female. The tumor presented as a rapidly growing cervical mass comprising a central area of carcinoma ex pleomorphic adenoma and a peripheral circumferential area of OGCT. The immunohistochemical staining pattern was phenotypically consistent with bone marrow-derived CD14+/CD45+ MOMC. This case is the first report of a salivary OGCT in Korea.

When vitrectomy is performed in eyes that have undergone glaucoma surgery, the site of sclerotomy often overlaps with the previous glaucoma operation site. It can lead to serious complications such as postoperative hypotony, leakage, and/or infection. Our technique involves modification of surgeon's position and two sclerotomy sites 45° away from the original position, with an infusion cannula inserted infranasally to avoid damage to the glaucoma drainage implant or filtering bleb. The modified approach was applied to seven eyes with various indications. Vitrectomy was successfully completed, and there were no sclerotomy site complications, leakage, or hypotony in any case. Good intraocular pressure control was maintained throughout the postoperative course in all cases.
