Juvenile granulosa cell tumor is rare but one of the common congenital testicular neoplasms. Although histological features are typical of its ovarian counterpart, testicular juvenile granulosa cell tumor has a distinctly different clinical presentation. We report a case of juvenile granulosa cell tumor arising in the cryptochid testis of a 4-day-old newborn. A 6 5 5 cm sized multilocular cyst containing thick, mucinous fluid was found in the peritoneal cavity. The external surface of the cyst was smooth and the septae were relatively thin. The cyst consisted of numerous mucin-filled, cystic follicles lined by cells having vacuolated cytoplasm and round to oval dark nuclei without grooves. Cells resembling granulosa cells of an ovarian follicle were also observed in the intervening stroma forming irregular solid nests.

Injuries of the posterior cruciate ligament have almost universally been treated nonoperatively in the past due to indignity of this complex structure. Recent studies have shown new informations on the anantomical, histological, biomechanical characteristics of the Posterior cruciate ligament PCL), and thereby interest of reconstruction surgery is increasing. But intraarticular PCL reconstruction still remains one of the most challenging problems in knee surgery. Although, various types of graft and surgical techniques have been used for reconstruction, results of surgery has been variable. In this study, three different methods of graft fixation for PCL reconstruction are evaluated biomechanically to determine the effect on mechanical property of reconstructed PCL using 30 porcine knees. Grafts used in this study were bone-patellar tendon-bone fixed with interference screw and Achilles tendon tied with suture. Additionally, five original PCLs were also tested by Instron universal testing instrument to determine its mechanical proprety. Tensile test was performed at extended knee position. It was demonstrated that mechanical strength of bone-patellar tendon-bone graft is superior to that of Achilles tendon graft. All of the failures of bone-patellar tendon-bone graft and Achilles tendon graft occurred at tibial fixation site whereas original PCLs which failed at proximal midsubstance of ligament. In conclusion, tensile strength of Bone-patellar tendon-bone graft used for PCL reconstruction is higher than that of Achilles tendon but latter can be used in terms of as clinical meanings.

Syphilis was known to be generalized disease and it had been decreased until 1960's. But, it has been increased again recently. The author analysed the 22 cases of congenital syphilis which were treated at department of orthopaedic surgery at Ewha Womans University Hospital from Jan. 1979 to July 1983 and the following results were obtained. 1. There were no significant changes of the number of patient by years. 2. Common symptom and sign were hepatosplenomegaly(84%), fever(62%) and skin changes(50%), and pseudoparalysis was observed in one case. 3. Radiologic bone changes were observed in 11 cases (50%) and the following results were obtained: a. Below the two week old, there was relatively low incidence of bone change with 22%. b. There was high incidence of bone change in prematurity with 75%. c. Common features of bone changes were periosteal reaction, osteochondritis and metaphysitis (91%). Pathologic fracture was observed. in one case. 4. Although we have observed the bone changes only in 50% of cases, all the other reports has reported more than 80% and we thought that radiologic bone change would aid the diagnosis of congenital syphilis.

Background: Dengue fever is considered one of the transfusion-transmissible emerging infectious diseases. Dengue fever has been reported every year by the Korea Disease Control and Prevention Agency (KDCA). Because a blood donor screening assay to detect the dengue virus (DENV) as an agent of dengue fever is not performed, the risk of transfusion-transmitted DENV infection needs to be assessed. Methods: This study collected the data of DENV infected cases from the Infectious Disease Portal of the KDCA, the data of blood donors and blood components from the Blood Information Management System of the Korean Red Cross, and the data of travelers to major dengue outbreak countries from the Korean Tourism Organization.All data were from 2016 to 2018. A risk assessment was performed using European Up-Front Risk Assessment Tool (EUFRAT). Results: The risk of DENV-infected red cells and platelet concentrate was higher than that of plasma and apheresis platelet. Nevertheless, the risk of the DENV infected blood component was shown to be less than one case per year for all kinds of blood components. Conclusion All the DENV infected cases in Korea were overseas travelers. Therefore, the risk of transfusiontransmissible DENV infection is very low. On the other hand, continuous observation and monitoring are required because Aedes albopictus as a vector of DENV is found in Korea, and the increase in reported cases may lead to domestic infections.

Lung cancer is the most common fatal malignant lesion in both sexes. Detection of the solitary pulmonary nodule is important because surgical series up to a third of solitary pulmonary nodules are bronchogenic carcinoma. Bronchioloalveolar cell carcinoma is a rare primary lung cancer and surgery is treatment of choice in brochioloalveolar cell carcinoma. We experienced a case of broschioloalveolar cell carcinoma in solitary pulmonary nodule with cavitary lesion in chest CT scan, which is an uncommon finding in brochioloalveolar cell carcinoma.

PURPOSE: To evaluate clinical usefulness of magnetic resonance angiography(MRA) as a diagnostic modality and for treatment planning of intracranial arteriovenous malformations(AVM). METHODS AND MATERIALS: In 14 patients with intracranial AVM which were confirmed by operations, radiologic studies and clinical evaluations, magnetic resonance imaging(MRI), MRA and conventional angiography(CA) were retrospectively reviewed with specific regards to nidus depiction, detectability of feeding arteries and draining veins, and number and anatomic consistency of these vessles. MRA was obtained by 3 D TOF, 2 D PC, and 3 D methods with adequate VENC selection. RESULTS: Nidus of AVM was well demonstrated in MRI and MRA, and no remarkable difference in detection and size estimation of nidus among MRI, MRA and CA except 2 cases of associated intracranial hemorrhage, in which 3 D PC MRA well depicted nidus that were not visualized on MRI because of subacute hemorrhage. Feeding arteries were well demonstrated on 3 D TOF and 3 D PC MRA. Dilated draining veins were well depicted on 3 D PC MRA by scannig with adequate VENC selection, and the results were no remarkable difference compared with the ones on CA. CONCLUSION: MRA of a consecutive scan after MRI is a excellent modality for evaluation and treatment planning of intracranial AVM, and possible substitutive method for CA except for radiotherapy or transarterial embolization.

Osteochondroma of long bone are common lesions : however spinal involvement may occur in 2.5% to 7% of all, and usually occurs from the neural arch of spinous process. Neurological complications are rare, occurring in less than 1% of patients of them. The authors report a solitary osteochondroma occurring in the lamina of C5, causing spinal cord compression.

Pulmonary thromboembolism (PTE) is a significant cause of death in the hospitalized patient in the western and developed countries. The development of PTE and venous thrombi is associated with many and various factors, including that physicians fail to provide adequate prophylaxis to the high risk patients. The authors studied 74 legal autopsy cases performed from 1996 to 2000 at the Headquarters of National Institute of Scientific Investigation, Seoul, Korea. We learned that ceasarian section was the most common precedong trauma in PTE death in legal cases. Excluding Ceasarian section cases, major mechanical injuries, male gender and aging were common factors associated with PTE. Obesity was a common factor in all kinds of trauma. Deep vein thrombi were documented in majority cases and ambulation was a critical triggering cause for the thrombi making PTE. Clinical diagnosis was not so satisfactory.
