Hip and knee replacement arthroplasty is one of the important causes of pulmonary embolism, of which the incidence was reported to be from 2 to 16% But, there are no reports about the incidence of pulmonary embolism after these operations in Korea. The authors' intention was to study the incidence and clinical manifestations of pulmonary embolism after hip and knee surgery. Lung perfusion scans and inhalation scans were done preoperatively and 7 days postoperatively for 139 hip or knee replacement arthrosplasty patients in Asan Medical Center. We studied 62 cases of avascular necrosis of the femoral head, 33 cases of femur neck fractures, 45 cases of degenerative arthritis of the hip and knee joints and 17 cases of other diseases. In this study, hip replacement arthroplasties were done in 114 cases, knee replacement arthrosplasties in 25 cases. On preoperative lung scan, high or intermediate probability findings of pulmonary embolism were shown in 18 cases and all of them were asymptomatic. 139 cases showed normal or low probability on preoperative lung scan, of which 5 cases were changed to high probability and 7 cases to intermediate probability on postoperative lung scan. Four of the 7 intermediate probability cases were confirmed to be pulmonary embolism on pulmonary angiography. Of these 9 cases, hip replacement arthroplasties were done in 6 cases and knee replacement arthroplasties in 3 cases. There were 5 cases of osteoarthritis of hip and knee, 3 cases of avascular necrosis of femoral head and 1 case of femoral neck fracture. We concluded that preoperative and postoperative incidences of pulmonary embolism in Korea were similar to those in western countires. Most of the pulmonary embolism patients were asymptomatic and so lung perfusion scans and inhalation scans were helpful in the early diagnosis of pulmonary embolism.

Biological behavior of malignant tumors has been assessed by morphological grading, clinical staging, and estimating other tumor markers. Recently DNA ploidy measured by flow cytometry and image analyser has been suggested as an additional useful indicator of the tumor behavior. In order to extract useful tumor cell-specific information in ovarian mucinous tumors, DNA contents and other morphologic parameters were measured by image analysis and DNA ploidy was also measured by flow cytometry. In all cases of cystadenoma, DNA diploidies were observed. In borderline malignancy, DNA diploidies were chiefly observed except one case of polyploidy. In true malignancy, DNA aneuploidies were observed except one case of polyploidy and two cases of diploidies by image analysis, and except four cases of diploides and one cas of polyploidy by flow cytometry. The statistical significance were observed in DNA ploidy pattern by image analysis. In nuclear areas, perimeters and major axis, statistical significance were not observed. These results suggest that DNA ploidy pattern are more or less independent parameter as an additional useful indicator of the histological grade of malignancy and that image analysis are better than flow cytometry in detecting DNA aneuploidy.

The pulmonary cytology has reached a high level of accuracy. By the examination of the sputum and/or bronchial brushings, it is now possible to make a diagnosis in 70% to 90% of patients with cancer. Primary melanoma of the lung is very rare and there have been reported about 20 cases in the world literature. We present a case of primary malignant melanoma of the lung in a 61-year-old male diagnosed by cytologic examination of sputum, bronchial brushing and aspirated pleural fluid. Histologic examination of bronchoscopic biopsy and examination of the skin and other primary sites confirmed the diagnosis.

Calvarium protects the brain, the most important organ. The defect of calvarium results in not only deformity but also fatal injury from the trauma. The cranial bone defects result from 1) removal of bone flap for intracranial decompression or infection 2) fracture 3) excision of tumor 4) craniectomy for craniosynostosis. The goals of cranioplasty are to protect the brain from trauma and make the aesthetically acceptable contour. From 1990 to 1995, we experienced twelve cases of cranioplasty using autogenous bone graft; 5 cases with rib bone, 3 cases with iliac bone, 2 cases with calvarial bone, and 2 cases with rib and calvarial bones. The result was very excellent without any significant complications.

The gastrointestinal polyp is a premalignant lesion in varying degree. According to the size, the pathology and the location of polyps, it should be removed. Polyps in the gastrointestinal tract can be removed by surgical excision, electrosurgery, cryotherapy, regional radiotherapy and laser therapy with some limitations. Considerable advance in therapeutic endoscopy as well as in diagnostic endoscopy along with newly developed instruments has now made it possible to excise gastrointestinal polyps by means of high frequency generator. We have underwent endoscopic polypectomy, strip biopsy and "O" ring ligation on gastric polyps in 112 patients who visited in this hospital from July l988 to January 1994, and the clinical characteristics including histopathology has been evaluated. Removed polyps were variable in size from less than 0.5 cm up to 4cm. Finally, we concluded that endoscopic polypectomy is a safe and relativly simple procedure and postpolypectomy complication can be considerably reduced by conservative antiulcer therapy.

Endoscopic injection sclerotheraphy(EIS) was an effective method for treatment of bleeding esophageal varices. However, it might be associated with some undesirable complications. Endoscopic variceal ligation(EVL) is a recently developed method for control of active variceal bleeding and eradicating esophageal varices with similar efficacy and minimal risk of complications compare to EIS. We performed EVL in 40 patients who had recently bled from esophageal varices. Total 198 variceal ligations were performed during 64 separate EVL session. Control rate of acute bleeding was 90%(36 of 40patients) and 4 patients died after EVL because of failure of bleeding control. Rebleeding following initiation of EVL occured in 5 patients-three patients were successfully controlled by EVL, one patient was controlled but eradication was impossible and one patient died. Varices were eradicated or reduced to grade I in 31(86.1%) of 36 survivors by 1-9 ligation(mean 5.0) in l-4 EVL sessions(mean 1.6). After EVL, there were mild complications-mild substernal discomfort in 4 patients, mild dysphagia in 2 patients and fever in 2 patients. These results suggest that EVL is a safe and effective method for treatment of bleeding and eradication of esophageal varices with less complication.

Purpose: The greatest concern in the androgen replacement therapy (ART) is the possible side effects to the prostate. We evaluated the effects of ART focusing on the prostate specific antigen (PSA). Materials and Methods: From 2003 to 2006, 47 patients 44 to 75 years old (mean age 60.1) received ART. At baseline and after ART, digital rectal examination, serum testosterone and PSA measurement and transrectal ultrasonography were evaluated. Mean follow-up was 7.9 months (range 1 to 41). Patients were classified into two groups based on the initial PSA level, as PSA levels of 2.5 ng/ml or greater (group 1) (n=29) and PSA levels of less than 2.5 ng/ml (group 2) (n=18). Results: ART significantly increased serum testosterone, PSA and free PSA levels. However, prostate volume did not change significantly. When serum PSA was compared, the increase of PSA levels was greater than in high PSA group (group 1) than in group 2, although the ratio between the two groups in PSA increase was 38.3% for group 2 and 18.2% for group 1, respectively. A total of 4 patients (16.7% of group 1 and 3.4% of group 2) with a serum PSA level greater than 4 ng/ml after ART underwent a prostate biopsy but no patients were found to have prostate carcinoma. Conclusions: Rates of PSA elevation (>4 ng/ml) and prostate biopsies were higher in patients with high baseline PSA level (> or =2.5 ng/ml) than in those with PSA level less than 2.5 ng/ml who received ART. However, our findings suggest that an increased risk of prostate cancer was not associated with ART.

PURPOSE: Acute thrombosis of arteriovenous graft (AVG) has been treated by surgical thrombectomy; however, endovascular treatment became an alternative treatment option recently. The purpose of this study is to evaluate the effectiveness of endovascular treatment for acute thrombosis of AVG (EndoAVG) by primary endovascular treatment strategy. METHODS: This is a retrospective study of patients who underwent EndoAVG from January 2003 to December 2010 in Inha University Hospital. The patients' clinical characteristics and EndoAVG procedures were reviewed by electronic charts and X-ray films. Clinical success was defined as the residual stenosis below 30% or success of hemodialysis. RESULTS: Thirty-eight patients were enrolled. The mean age was 64+/-15.4 years in the success group and 58+/-17.2 years in the failed group. The mean duration from AVG formation to endovascular thrombectomy was 19.2+/-29.5 months. The success rate of EndoAVG was 84.2% (32/38). There were three complications after EndoAVG: two brachial artery thromboses and one rupture of a vein at the ballooning site. Six months, twelve months and twenty-four months secondary patency rate were 77.5%, 65.5%, and 42.5%, respectively. CONCLUSION: The success rate of EndoAVG was 84.2%. Its result is compatible with open thrombectomy and can be a good alternative option for the treatment of acute thrombosis of AVG. Larger number of cases is required for stronger study.

BACKGROUND: Pneumonia is the most common cause of death among patients with infectious disease in Korea. However, studies of pneumonia with septic shock in patients presenting to the emergency department are limited. The aim of this study was to investigate the prognostic factors associated with pneumonia with septic shock in patients presenting to the emergency department. METHODS: From January 2008 to September 2014, patients with pneumonia with septic shock admitted through the emergency department were retrospectively examined. RESULTS: Of the 561,845 patients who visited the emergency department, 398 were admitted for pneumonia with septic shock. The 28-day mortality rate in these patients was 36.4%. The independent prognostic factors were old age (>70 yrs) (odds ratio [OR], 2.42; 95%, confidence interval [CI], 1.35-4.32), Acute Physiology and Chronic Health Evaluation (APACHE) II score (OR, 1.04; 95% CI, 1.01-1.08), leukopenia (OR, 3.63; 95% CI, 1.48-8.94), prolonged PT-INR (OR, 2.53; 95% CI, 1.41-4.54), and hypoxemia (OR, 2.88; 95% CI, 1.30-6.38). CONCLUSIONS: A poor prognosis of patients with pneumonia is associated with old age (>70 yrs), increased APACHE II score, leukopenia, prolonged PT-INR, and hypoxemia.
