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.

A 13-month-old boy had irregularly shaped, erythematous to dusky red, slightly raised patches and plaques on the left antecubital fossa and arm for 7 months. The lesions were firm and tender. Histopathologically the lesion consisted of small, circumscribed, angiomatous tufts and lobules with a cannonball appearance scattered throughout dermis, a characteristic feature of tufted angioma. For 15 weeks, interferon-a intralesional injections have been performed and the lesions showed an improvement.

BACKGROUND: Demand for emergency medical information is high according to the health information use, utilization and demand survey for on the Internet. In spite of high demand for emergency information service, emergency information service on-line and off-line are very limited. Therefore, it is necessary to develop a website providing emergency medical information and emergency medical resources information by linking emergency medicine where timely information is required with the Internet technology for health promotion of the public. OBJECTIVE: This study is conducted to develop and evaluate a Web site to provide information on emergency medicine and resources for health promotion. METHODS: To identify and specify users' requirements for the emergency medicine related information, online survey was performed for 209 Internet users who visited the Healthguide. Based on this survey results, we developed content for emergency medical information service: cause, risk factors, prevention, treatment, facilities, laws and rules, policy and statistics of emergency medicine. To evaluate the web site developed in this study, twenty health and nursing informatics experts were recruited and asked to rate using an evaluation tool. RESULTS: This content was integrated into the healthy life (http://healthguide.kihasa.re.kr/health_life/emergency/pages/index.html), which is a service component of the Healthguide. This approach was expected to increase accessibility and usability of implemented services. The rating score of the website was fairly high with mean 3.9(SD 0.6) out of 5.0. According to each evaluation criteria, purpose of the site, easiness of use, relevancy, and reliability were scored 4.1-4.2 and authority and accuracy 3.8-3.9 and currency 3.5-3.7. This evaluation results will be fed back to the Healthguide for operation, maintenance, and upgrade in the future.

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.

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.
