1.Unruptured Cornual Pregnancy: A Case Report.
Yonsei Medical Journal 1975;16(1):40-43
Cornual pregnancy is very rare and its diagnosis is very difficult due to the distensibility of the uterus at the cornu. However, tender cystic enlargement at one horn of the uterus is suggestive of this type of ectopic gestation in this case. A case is reported of unruptured cornual pregnancy, diagnosed before operation, with a review of the literatures.

Twenty nine cases of wrist tuberculosis were reviewed(19 joint involvement cases and 4 tendon involvement cases) and twenty three cases were followed up more than one and half years. The mean follow up period was 26.7 months. Synovectomies were not satisfactory in cases of joint involvement and they were useful only in cases of tendon involvement. Arthrodesises were used for 16 cases of joint involvement and were satisfactory in 87,5 percent by Robin's criteria. Finger stiffness was most serious complication(initially, 8.7 percent and finally, 34.8 percent) and it is suggested that early motion of fingers after arthrodesis can prevent this complication.

OBJECTIVES: The aim of the present study was to evaluate changes in the management and 5-year survival rates of patients with oral cancer in our department over a 30-year period. MATERIALS AND METHODS: We investigated the patient distributions, treatment methods, method of neck dissection according to cancer stage, and 5-year survival rates for 700 oral cancer patients over the periods of 1982-1996 (256 patients), 1999-2006 (248 patients), and 2007-2011 (196 patients). RESULTS: Stage IV patients were the largest group in all of the time periods evaluated. Although surgery and radiotherapy were the most common methods in all periods (over 50%), the prevalence of patients who underwent concomitant chemoradiotherapy increased from 7.0% to 16.2%. The use of radical neck dissection decreased from 43.0% to 5.3%, while conservative surgical methods increased from 24.1% to 76.3%. Lastly, the overall 5-year survival rate increased from 31.6% to 63.5% during the study period. CONCLUSION: Although the 5-year survival rate reached the same level as that of other developed countries during the course of our study, most patients continue to come to the hospital with stage IV disease. In order to increase the 5-year survival rate of oral carcinoma, it may be necessary to improve public education and social efforts relevant to early diagnosis.

We herein describe a 70-year-old woman who presented with respiratory failure due to extensive lung adenocarcinoma. Despite advanced disease, care in the intensive care unit with ventilator support was performed because she was a newly diagnosed patient and was considered to have the potential to recover after cancer treatment. Because prompt control of the cancer was needed to treat the respiratory failure, empirical treatment with an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor was initiated before confirmation of EGFR-mutant adenocarcinoma, and the patient was successfully treated. Later, EGFR-mutant adenocarcinoma was confirmed.

Castleman's disease or angiofollicular lymph node hyperplasia is a rare lymphoproliferative disorder. Complete surgical resection was recommended in unicentric Castleman's disease. Radiotherapy was considered alternative therapeutic option. However, there have been consistent favorable responses to radiotherapy. We also experienced two cases of uncentric Castleman's disease salvaged successfully with radiotherapy. This paper described these cases and reviewed the literature about Castleman's disease treated with radiotherapy. Reviewed cases showed that radiotherapy is a successful treatment option in unicentric Castleman's disease. Furthermore, our report confirms the radiotherapy role in uncentric Castleman's disease.

Total extrusion of the talus is a very rare injury. If the talus is found in a short time, it can be restored to its original position. If the talus is missing or found too late, however, surgeons may attempt tibiocalcaneal arthrodesis or use a pseudoarthrosis without repositioning the talus. As direct tibiocalcaneal arthrodesis may shorten the lower extremity, tibiocalcaneal arthrodesis using a sandwich block can be performed. We performed tibiocalcaneonavicular arthrodesis using a sandwich block to treat a patient with open talus extrusion caused by a motorcycle accident and obtained good clinical results.

PURPOSE: To date, anatomical imaging modalities of the pelvis and tumor markers have been the mainstay of surveillance for recurrent ovary cancer. This study aimed to assess the role of 18F-FDG PET/CT in evaluation of ovary cancer recurrences, especially in comparison with enhanced CT and tumor marker CA 125. Materials and METHODS: 73 patients who had PET/CT scan for restaging of confirmed ovary cancer, and additional imaging with enhanced CT of the pelvis within one month were included. CA 125 level was available in all patients. From the PET/CT images, maximum standard uptake values (SUVmax) of suspected recurrence sites were recorded. Confirmation was available through re-operation or biopsy in 26 cases, and clinical assessment with series of follow-up images in 47. RESULTS: PET/CT had 93% sensitivity and 88% specificity for detecting recurrent ovary cancer. Enhanced CT of pelvis had sensitivity and specificity of 83% and 88%, and CA 125 50% and 95%. CONCLUSION: PET/CT has higher sensitivity for detecting recurrent ovary cancer compared to enhanced CT though the differences were not significant. PET/CT has significantly higher sensitivity than CA 125. However, the three tests all agreed in only 43% of the recurrence cases, and recurrence should be suspected when any of the tests, especially PET/CT, show positive findings.

PURPOSE: The major source of acute peripheral arterial occlusion has been embolization from the heart. However overall improvement in medical care have increased life spans, resulting in significant increase in the incidence of systemic atherosclerosis and thrombotic occlusion of peripheral vessels. Recently, occlusion from in situ thrombosis has surpassed occlusion from embolization as the major cause of acute arterial occlusion. The introduction of the balloon catheter technique in 1963 dramatically simplified the technical aspect of surgical therapy for acute arterial occlusion and it became the main modality of the therapy. Recently, numerous reports have documented increased identification of intraluminal defects after arterial surgery using angioscopy as compared with those using intraoperative arteriography, and for this reason, the use of intraluminal angioscopy has grown in popularity. METHODS: We analyzed clinical characteristics and treatment results in patients with acute arterial occlusion. The variables studied include location, etiology, time interval from occurrence of occlusion to performance of thromboembolectomy. RESULTS: There were 41 men and 4 women and most prevalent age group was in 7th decades. The causes of acute arterial occlusion were embolism in 21 cases (46.7%), thrombosis in 24 cases (53.3%). The primary source of embolism was heart in 20 cases as a result of ischemic heart disease (n=11, 52.4%) and atrial fibrillation (n=9, 42.9%). Two patients in embolic group died of cardiogenic shock and were in shorter duration group (<24 hours). Iliac arterial occlusion group was associated with highest amputation rate (23.1%). Amputation rates were 12.5% for thromboembolectomy performed within 24 hours of onset of symptoms, and 17.4% when performed after 48 hours. We used angioscopic technique in limited cases of 5 patients to detect residual thrombus, intimal flap and other intraluminal defects. CONCLUSION: To improve outcome, early diagnosis and early treatment are essential. Direct visualization of the arterial lumen with angioscopy during thromboembolectomy procedure would provide a more reliable method of assessing luminal morphologic characteristics than angiography alone.

INTRODUCTION: The location of parotid gland tumors in the superficial or deep lobes can affect the time and difficulty of operations. Therefore, accurate preoperative evaluation of the tumor location is important for surgical outcomes. MATERIALS AND METHODS: A total of 16 patients with parotid gland tumors and who underwent a parotidectomy between April 2003 and March 2011 were retrospectively reviewed in terms of demographic background, tumor location, surgical treatment, and treatment outcomes. Tumor location was estimated by four landmarks on contrast enhanced computerized tomography scans, which were Conn's arc, the facial nerve (FN) line, the Utrecht line, and the retromandibular vein. Tumor location was confirmed by relative position depending on the facial nerve during surgery. It was assumed positive since the tumor lies in the superficial lobe of the parotid gland, the sensitivity, specificity, positive predictive value, negative predictive value, and efficiency of each landmark were evaluated. RESULTS: Our result revealed that the facial nerve line had a sensitivity of 83.3%, specificity of 100%, positive predictive value of 100%, negative predictive value of 71.4%, and efficiency of 87.5%. Some would be more efficient preoperative evaluation methods of the relationship of parotid gland tumors to the facial nerve than others. CONCLUSION: In our study, the FN line was found to be the most reliable analysis method.
