Primary intimal sarcoma of the pulmonary artery is a rare disease and there has been no report of any case originating from the pulmonary valve. Recently we experienced a 62 year-old female patient who had a primary intimal sarcoma of the pulmonary valve with distal metastasis. She was brought to medical attention due to exertional dyspnea facial edema productive coughing and general weakness for 1 month. Chest CT and echocardi-ography suggest an acute pulmonary thromboembolism or tumor. Exploration showed a large polypoid mass arising from the pulmonary leaflets and multiple masses on distal pulmonary arteries. We replaced the pulmonary valve and reconstructed the pulmonary artery. She received radiotherapy 1 month postoperatively and now 4 months after surgery she has begun receiving chemotherapy.

PURPOSE: The aim of this study was to examine the relationship between tooth loss and sub-clinical atherosclerosis in Korean adults. MATERIALS AND METHODS: The subjects were part of a cohort study conducted in Ansan city by the Korea University medical school as part of the Korean Genome project. 749 subjects over than 40 years old were evaluated. After taking panoramic radiography, the amount of tooth loss was calculated. The intima-media thickness (IMT) was assessed by using ultrasonography at the common carotid artery. Traditional cardiovascular risk factors for atherosclerosis were also evaluated. The relationship between tooth loss and the IMT was evaluated using ANOVA with Scheffe's multiple comparison method in univariate analysis. Multiple regression analysis was also performed to determine the significance between the IMT and tooth loss. RESULTS: With age, tooth loss increased, but there was no significant increase in other traditional cardiovascular risk factors. Univariate analysis revealed the IMT to be positively related with the amount of tooth loss. Regression analysis of the IMT in the anterior and posterior tooth loss revealed that only the posterior tooth loss was significantly related with the IMT at all sites of the common carotid artery (right far wall, P = .015; left far wall, P = .008; right near wall, P < .001; left near wall, P = .001). CONCLUSION: This study verified the positive relationship between the increased tooth loss at the posterior area and the accumulation of atheroma in arteries.

Choriocarcinoma is a relatively rare malignancy of which characteristic is rapid metastasis to the other organs. It is related to the previous gestation or originated from the teratoma. Choriocarcinoma is mostly originated from the intrauterine chorionic villi, but it is rarely originated from the utreine cervix, fallopian tube, ovary, vagina and pelvic cavity. Primary choriocarcinoma of the fallopian tube is exceedingly rare and it is originated from ectopic tubal pregnancy, tubal migration from the intrauterine pregnancy or intratubal teratoma. 9 Symptoms and signs of the choriocarcinoma originated from the ectopic pregnancy are abdominal pain, vaginal bleeding, palpable adnexal mass, positive pregnancy test and amenorrhea. Thus it is difficult to distinguish choriocarcinoma from ectopic pregnancy on the basis of symptoms before the microscopic diagnosis presented.20 Effective treatment of choriocarcinoma is chemotherapy. Additional operation is possible. B-HCG is a useful measure for the follow up. We experienced a 36-year-old multigravida Korean woman who was diagnosed as the rupture of ectopic pregnancy after left salpingectomy in our hospital and then confirmed primary choriocarcinoma of the fallopian tube without metastasis on microscopic finding. Postoperative chemotherapy was performed with methotrexate. The follow up of disease is still on going at two month intervals and she has remained healthy, We report this case with review of literatures.

OBJECTIVES: This study sought to evaluate the efficacy of collagen graft materials, as compared to other graft materials, for use in healing calvarial defects in rabbits. MATERIALS AND METHODS: Ten mm diameter calvarial defects were made in ten rabbits. The rabbits were then divided into 4 groups: control, autogenous bone graft, SureOss graft, and Teruplug graft. Bone regeneration was evaluated using histological and radiographic methods. RESULTS: Based on visual examination, no distinct healing profile was observed. At 4 weeks after treatment, histological analysis showed there was no bone regeneration in the control group; however, at 8 weeks after treatment, new bone formation was observed around the margin of the defective sites. In the autogenous bone graft group, new bone formation was observed at 4 weeks after treatment and mature bone was detected around the grafted bone after 8 weeks. In the SureOss graft group, at 4 weeks after treatment, acute inflammatory and multinuclear cells were noted around the grafted materials; at 8 weeks after treatment, a decrease in graft materials coupled with new bone formation were observed at the defective sites. In the Teruplug graft group, new bone formation was detected surrounding the bone margin and without signs of inflammation. There were statistically significant differences observed between the graft and control group in terms of bone density as evidenced by radiographic analysis using computed tomography (P<0.05), particularly for the autogenous bone graft group (P<0.001). CONCLUSION: These results suggested that autogenous bone, SureOss and Teruplug have the ability to induce bone regeneration as compared to an untreated control group. The osteogenic potential of Teruplug was observed to be lower than that of autogenous bone, but similar to that of SureOss.

We experienced a case of transient right-sided heart failure after angioplasty of membranous obstruction of the inferior vena cava confirmed by sonography and an inferior vena cavogram. Angioplasty involved the use of a self-expandable metallic stent, but after successful recanalization of the obstruction , the patient became dyspneic. Chest radiography revealed mild cardiomegaly with pulmonary congestion, but this was resolved spontaneously. For the prevention of serious heart failure, we recommend preprocedural evaluation of cardiac function.

Polycystic ovary syndrome is characterized by symptoms of oligomenorrhea, amenorrhea, infertility, hirsutism and obesity. It is known that the women with such diseases would have higher risks to coronary heart diseases, hypertension, DM and endometrial cancer later on, Known risk factors of endometrial cancer are nullipara, late menopause, obesity, DM, unopposed estrogen, tamoxifen treatment, and atypical endometrial hyperplasia ect. 75% of endometrial cancer occurs in age over 50 and 4% of endometrial cancer occurs in age under 40. Particulary endometrial cancer concurrent polycystic ovary syndrome occurs usually in people under age 40 and is commonly well differentiated cell type and is related to good prognosis. We experienced a case of endometrial cancer with polycystic ovary syndrome, who was early dignosed, presented with infertility and got an operation in our hospital, and report this case with a brief review of literature.

Background: The relationship between cystitis glandularis (CG) and bladder malignancy remains unclear. Methods: We identified the oncologic significance of CG at the molecular level using liquid chromatography-tandem mass spectrometry-based proteomic analysis of 10 CG, 12 urothelial carcinoma (UC), and nine normal urothelium (NU) specimens. Differentially expressed proteins (DEPs) were identified based on an analysis of variance false discovery rate < 0.05, and their functional enrichment was analyzed using a network model, Gene Set Enrichment Analysis, and Gene Ontology annotation. Results: We identified 9,890 proteins across all samples and 1,139 DEPs among the three entities. A substantial number of DEPs overlapped in CG/NU, distinct from UC. Interestingly, we found that a subset of DEP clusters (n = 53, 5%) was differentially expressed in NU but similarly between CG and UC. This “UC-like signature” was enriched for reactive oxygen species (ROS) and energy metabolism, growth and DNA repair, transport, motility, epithelial-mesenchymal transition, and cell survival. Using the top 10 shortlisted DEPs, including SOD2, PRKCD, CYCS, and HCLS1, we identified functional elements related to ROS metabolism, development, and transport using network analysis. The abundance of these four molecules in UC/CG than in NU was consistent with the oncologic functions in CG. Conclusions Using a proteomic approach, we identified a predominantly non-neoplastic landscape of CG, which was closer to NU than to UC. We also confirmed a small subset of common DEPs in UC and CG, suggesting that altered ROS metabolism might imply potential cancerous risks in CG.

PURPOSE: The aim of this study was to investigate about the natural course of idiopathic frozen shoulder and the efficacy of conservative treatment. MATERIALS AND METHODS: Twenty-five cases of unilateral frozen shoulder (study group) treated conservatively by intra-articular steroid injection and staged passive stretching were prospectively followed for average 9.1 months, the outcome was assessed in terms of motion range and the function score derived from patients' self-evaluation, and timing of improvement was searched. Compared with study group, 20 patients (control group) , who were diagnosed as idiopathic frozen shoulder but didn't undertake specific treatment, were checked at average 40 months. RESULTS: Eighteen cases (72%) of the study group had residual symptom, which was mild in most cases. Range of motion less than 80% of normal side was noted in 2 cases. Intra-articular steroid injection was effective for pain relief in 75%. In the control group, one case showed decreased motion and 2 case had mild pain. Comparing with the control group, the study group was improved significantly & statistically faster. CONCLUSION: It is construed that the long term result of idiopathic frozen shoulder is excellent and the combined effect of steroid injection and stretching shortens the duration of disease. Operative treatment for idiopathic frozen shoulder, if indicated, needs to be decided after long term follow-up.

Amidarone is one of the most commonly prescribed anti-arrythmic agents for almost all arrythmias, whether atrial or ventricular in origin. There are several side effects associated with amiodarone therapy. These include corneal deposits, abnormal liver function tests, hyper and hypothyroidism, bluish discolorations of the skin, bone marrow suppression, coagulopathies, peripheral neuropathies, and pulmonary toxicity. Amiodarone-induced pulmonary toxicity(APT), which was first described in 1980, is potentially serious side effects that are believed to develop in 5% of patients. Doctors often assume that APT occurs only when high amiodarone doses are used for a long time, but in practice a low maintenance dose of amiodarone may also be toxic. In this report, a case of amiodarone-induced pulmonary toxicity after a long course of a low dose therapy for refractory supraventricular arrythmia is described.

BACKGROUND: The kidney function with aging is the dramatic changes of human organ system. Recent studies have suggested that many risk factors such as smoking and obesity could contribute to the progression of chronic kidney disease, though there is a little evidence in the literature showing this relationship in the general population prospectively. We aimed to identify the change of calculated glomerular filtration rate (GFR) with aging in healthy adults and to evaluate the effect of prior risk factors to the change of GFR after 5 years follow-up. METHODS: This study included 3,928 healthy adults who participated in health screening examinations in 1997 and 2002. Average age was 42 +/- 5 years in 2002 (2,955 males, 973 females). The study population had no diabetes, hypertension, renal disease and other major diseases. The clinical and laboratory monitoring were performed each on 1997 and 2002; 5 years follow-up. In this study population, GFR was calculated using the MDRD (Modification of Diet in Renal Disease) equation: calculated GFR = 186 X Scr(-1.154) X age(-0.203) X (0.742 if female). We evaluated the change of calculated GFR with aging and compared the change of calculated GFR after 5 years follow-up according to smoking and obesity. RESULTS: The decreased GFR in adults was associated with aging. The mean calculated GFR (mean +/- SD) was 82.2 +/- 9.7 mL/min/1.73 m2 at 1997, 76.2 +/- 9.1 mL/min/1.73 m2 at 2002, respectively, so decrease is 6.0 mL/min/1.73 m2/yr (1.2 mL/min/1.73 m2/yr). The change of calculated GFR was more decreased in smoking group (5.2 vs 5.0 mL/min/1.73 m2) and obesity group (6.4 vs 5.7 mL/min/1.73 m2), but not statistically significant(p>0.05). CONCLUSION: Aging is an important factor of decrease in renal function. The mean decrease in calculated GFR was 1.2 mL/min/1.73 m2/yr. We suggest that smoking and obesity had some effects on decrease in renal function. These changes in renal function should be confirmed by a prospective study for a long period and in a large number of subject.
