The Kato-Katz (KK) method is a well-known method of fecal examination for helminthiases. Its diagnostic sensitivity was found very high for clonorchiasis. The present study evaluated the correlation of Clonorchis sinensis egg counts by the KK method with those by direct smear and formalin-ether (FE) technique. The egg counts obtained by the KK method (Y) were correlated with the counts by direct smear (X) with the equation of Y = 659.4 + 0.266X (r2= 0.738), but not with those by the FE method. The present study demonstrated that the KK method and direct smear were useful for both qualitative and quantitative diagnosis of clonorchiasis, especially in the field.

Arthroscopic anterior cruciate ligament reconstruction with bone-patella tendon-bone has been commonly using for ACL insufficient patients. Bone-patellar tendon-bone graft is a strong intra-articular substitute, which allows, by means of its bony end, a rigid fixation with early bone to hone healing. As a counterpart, potentially serious cornplications & donor site morbidity has been reported, such as patella fracture & patella tendon avulsion, anterior knee pain, patella tendinitis, dcmor site pain and bone defect. We suppose tightly packing the donor site bony defect with hetrograft (Lubboc) may be also useful. So, we analyzed the morphological change in bony defect and donor site morbidity between the group of non-replaced bony defect and the group of replaced bony defect using by heterograft (Lubboc). We replaceJ hetrograft into the patellar side bony defect in 15 knees and left alone in l5 knees. The average follow up period was 17 months. The results werc as follows: 1. Nearly norma1 appearance on the bony defect showed at the long tenn follow up roentgenogram in the group of replaced hetrograft, but scalloping on the pateltar bomp defect was seen in non-replaced group. 2. Donor site morbidity (pain or patellai tendinitis) was developed 8 knees in the replaced group, and 7 knees in the non-rep)aced group. 3. We conclude that the filled in the bony defect hy hone graft (heterografl:) can not decrease the donor site morbidi ty.

Anomalous development of the odonteid precess is an uncommon clinical occurence that can seriously impair the integrity af the atlantoaxial articulation. Absence of the odontoid process may be either congenital or acquired, but clinically the etiology is of little importance as the clinical signs and symptoms and the treatment are identical in both. We experienced a case of congenital absence of the odontoid process and good result was obtained from the posterior atlantoaxial fusion with hale-cast.

Because most of the hip fracture is endemic to an elderly population, high mortality and morbidity has been encountered due to the fatal complications such as pneumonia, thromboembolism, and decubitus ulceration. So, it is essential to achieve early ambulation with complete reduction by strong interoal fixation divices in order to reduce those complications. As early as 25 years ago McCarroll remarked that this fracture must be considered “unsolved until the incidence of aseptic necrosis and nonunion could be diminished or abolished. Since that time improved reduction method and many new strong fixation divices such as Jewett nail-plate, Massie nail, and compression hip screw have been developed to achieve more accurate reduction and rigid immobilization. The following clinical results were shown by analysis of 117 cases of hip fractures experienced in the Department of Orthopedic Surgery, Seoul National University in the past 5 years from Jan. 1974 to Dec. 1978. 1. Femoral neck fractures were 67 cases and intertrochanteric fractures were 36 cases. 2. The most common cause of hip fractures was slip or fall (70.1%). 3. Incidence of femoral neck fracture was most frequent in the 6th decade, and that of the intertrochanteric fracture was in the 7th decade that is compared with 7th and 8th decade of Caucasian respectively. 4. Old hip fracture more than 3 weeks after trauma was in the 53.6%, and especially that of neck fracture was about 57%. 5. In the classification of the hip fractures, transcervical neck fracture was most frequent (70.1%), and unstable type (79.5%) in the intertrochanteric fracture. 6. Knowles pin was usually used in the stable neck fracture, while compression hip screw used in the unstable neck fracture. 7. Jewett nail-plate was usually used after Dimon-Hughston reduction, and compression hip screw after anatomical reduction in the unstable intertrochanteric fracture. But in the stable fracture either Jewett nail-plate or compression hip screw was usually used after anatomical reduction. 8. Endoprosthesis (26 cases), and total hip replacement arthroplasty (8 cases) were usually carried out in the old femur neck fracture treated by total hip arthroplasty was better than that by endoprosthesis. 9. Avascular necrosis was 13.3%, and nonunion 20% in the femur neck fracture. Nonunion was 12.5%, and delayed union 4.2% in the intertrochanteric fracture. With the above mentioned results, the following conclusion is obtained: 1. It is recommended that open reduction or arthriplasty of the hip should be performed if the closed reduction of the fracture of femoral neck is not adequate. 2. Graden alignment index is a good criteria for adequate reduction of femoral neck fracture. 3. Malunion induces the fate of femoral head to be avascular in the femoral neck fracture. 4. Compression hip screw is a good stabilizer for unstable intertrochanteric fracture. 5. The position of femoral endoprosthesis for delayed or inadequately reduced femoral neck fracture may be replaced by total hip replacement. The clinical result of total hip replacement is far better than that of femoral endoprosthesis In the cases of arthroplasty indication.

A 53-year-old woman presented with dyspnea. She had undergone extended thymectomy for an invasive thymoma two months prior. CT revealed numerous small nodules in the lung. After that, she deteriorated owing to acute respiratory distress syndrome (ARDS), and the vascular surgeon planned veno-venous extracorporeal membrane oxygenation (ECMO). During percutaneous cannulation through the left femoral vein, a vascular injury was suspected, and the patient’s vital signs became unstable. Diagnostic angiography showed a ruptured left common iliac vein, and the bleeding was stopped by placement of a stent-graft. May-Thurner syndrome was diagnosed on abdominal CT. Here, we report a rare case of ECMO-related vascular injury in a patient with an unrecognized anatomical variant, May-Thurner syndrome.

The real time high resolution mechanical neurosonographic sector scanner is a convenient and useful instrumentfor detection of intracranial lesions in premature infants as well as low birth weight. From this experience,authors report with 104 neonates and infants who had been suspected intracranial hemorrhage and had been detectedand graded by sonography. The results were as followed: 1. The incidence of intracranial hemorrhage is 20 of 46(43.5%) neonates who had been studied before 3 days of age. But 7 of 16(43.7%) neonates showed ICH between the 4-7days of age. 2. There was no difference of prevalence in sex ratio in neonates with ICH. 3. There was closerelationship between ICH and gestational weeks. 15 of 27 (55.6%) neonates who were born under 32 gestational weeksshowed ICH was graded as 3 or 4 in 7 of 10. 4. 10 of 16(62.5%) neonate who were born under 1,500 gram body weighthad ICH within first 4 days. The severity of ICH was graded as 3 or 4 in 7 of 10. 5. The mode of deliveryinfluenced neonatal ICH incase of difficulty delivery such as forcep(4/4, 100%), vacuum (7/10, 70%), breech (3/3,100%), and C/S(13/33, 39.4%). 6. Incidence of ICH in neonates with pathologica lung conditions (29/40, 72.5%) washigher than ICH with normal chest findins(15/64, 23.4%). 7. For frequent follow up study of brain, neurosonographywas very helpul and economic in case of ICH, and could find congenital glioblastoma multiformed(1), and low gradeastrocytoma(1) incidentally.

Synovial sarcoma is a distinct and generally recognized soft tissue tumor that it’s origin still raises controversy. The synovial origin of synovial sarcoma has not been determined despite the accepted terminology implying synovium as stem cell. Three cases of primary synovial sarcoma (2 fibrous monophasic, 1 biphasic type) were studied with a panel of antibodies against different types of cytokeratin and other markers (EMA, CEA, vimentin, S-100 protein, lysozyme, 1-antichymotrypsin). Spindle shaped-cell in monophasic synovial sarcoma showed reactivity for CK7 and pancytokeratin. Epithelial cells lining of glands in biphasic synovial sarcoma reactive for CK7, pancytokeratin, EMA, and focally CEA but spindle cells only positive for vimentin. By electron microscopy, fibrous monophasic synovial sarcoma showed pseudogland formation with intercellular junctions of paired subplasmalemmal destiny and discontinuous basal lamina. These results indicate that synovial sarcoma showes epithelial differentiation. We believe that synovial sarcoma arises in pluripotential connective tissue cells that is able to be differentiated into both mesenchymal and epithelial components. So, synovial sarcoma have been considered carcinosarcoma of soft tissues depending on the type of differentiation.

A nested polymerase chain reaction (PCR) was applied to detect and identify pathogenic Yersinia enterocolitica and Y. pseudotuberculosis. We used photochemical postamplification procedure with 8-methoxypsoralen to control carryover contamination. Using the ail and inv gene, the sensitivity and specificity of DNA amplification by nested PCR was considerably improved. The amplified fragment sizes were 298 bp for the ail gene and 295 bp for the inv gene. Amplification was successful when the template was derived from three sources: purified DNA, aliquots of boiled bacterial suspension and aliquots of lysed bacterial suspension. The detection limits were 10 fg of DNA and 2 * 10 colony forming units (CFU) for Y. enterocolitica and 10 fg DNA and 2 CFU for Y. pseudotuberculosis.
