Leiomyosarcoma arising in the skin is rare tumor, and diagnosis usually is made microscopically. After local excision, these lesions recur in large proportion of pat ients. The authors herein report a 53-year-old male with leiomyosarcoma appeared in the skin of the right forearm and presenting as a dark reddish colored, 5*6cm in diameter, superficial ulcerated single firm nodule with intermittent pain. Histopathological examination showed poorly circumscribed tumor consisting of interlacing bundles of spindle shaped smooth muscle cells in the middle and lower parts of the dermis. The nuclei were hyperchromatic, large, vacuolated, and irregular in shape. Electron microscopic findings revealed cytoplasmic organelles such as rough endoplasmic reticulum and mitochondria of malignant smooth muscle cells in the paranuclear area, Characteristic subsarcoelmmal caveolae and dense plaque were noted and myofilaments were distributed in the peripheral cytoplasm. The tumor did not recur in 10 months' follow-up.

BACKGROUND AND OBJECTIVES: Angiogenesis is the process of new blood vessel development from preexisting vessel. In many human solid tumor, the extent of angiogenesis is one of the most significant prognostic factors that can be used to predict the patient survival rate and metastasis. The aim of this study is to investigate the role of new blood vessel formation in the thyroid tumors. SUBJECTS AND METHOD: We analyzed the microvascular density and proliferation index in the 70 cases of thyroid tumors by double immunohistochemistry with anti-CD34 and anti-Ki67 antibody. The microvascular density and Ki67 index were compared with the clinical parameters such as sex, age, stage, tumor extension, cervical lymph node metastasis, and prognostic factors, which were obtained through the retrospective review of the medical records. RESULTS: The microvascular density and Ki67 index were higher in malignant tumors than in benign tumors. Higher microvascular density and Ki67 index were associated with tumor stage and increased risk of AMES, AGES and MACIS scores. CONCLUSION: The microvascular density and Ki67 index may serve as significant prognostic factors in the differentiated thyroid cancer.

PURPOSE: Although, there have been many reports about factors involved in the severity and prognosis of organophosphate toxicity, there are few reports on integrated application of scoring methods using those factors for prognosis. Our report is about the possible application of such scoring methods in the early stage of organophosphate intoxication. METHODS: This study included organophosphate intoxication patients who were admitted to the Emergency department (ED) between March 1, 2004 and February 28, 2008. We limited enrolment in the study to patients who had required assisted mechanical ventilation and used atropine for therapy. This was a retrospective study about age, drug toxicity, mental status, existence of metabolic acidosis and QT prolongation for each patient. RESULTS: Thirty seven patients were enrolled in this study. Among the 37, 22 survived and 15 died. For survivors, drug toxicity and mental status were correlated with total dose of atropine, and the existence of metabolic acidosis was correlated with the duration of mechanical ventilation. Survivors had lower total scores than non-survivors. CONCLUSION: Application of scoring methods that include five factors (age, drug toxicity, mental status, existence of metabolic acidosis, existence of QTc prolongation) when acute, severe, organophosphate poisoning patients arrive at an ED can be helpful for their prognosis.

PURPOSE: Intravenous propofol anesthesia has been safely and effectively used in the ureteroscopic management of lower ureteral calculi. We investigated whether we can also use propofol anesthesia effectively for the treatment of middle and upper ureteral calculi. MATERIALS AND METHODS: We performed ureteroscopy with intravenous propofol anesthesia in 200 consecutive patients with ureteral calculi from July 1998 to December 2001. We divided them into 2 groups. Group 1 consisted of 59 patients, 48 men and 11 women, with upper and midureteral calculi, and group 2 consisted of 141 patients, 94 men and 47 women, with lower ureteral calculi. We compared safety, success rate, length of hospital stay and complication rate between the two groups. RESULTS: The overall success rate for ureteroscopy was 94.5% (189/200). Seven patients suffered perioperative complications, none of whom needed to change mode of anesthesia or remembered discomfort during the operation. In group 1, stone size, operation time and postoperative hospital stays were 7.5+/-3.2mm, 33.0+/-20.3 minutes and 1.9+/-1.0 days, respectively. The equivalent results were 6.2+/-2.9mm, 22.9+/-15.0 minutes and 1.4+/-0.9 days, respectively, in group 2. There were no significant differences in age, complication rate or success rate between the two groups. CONCLUSIONS: In patients with middle and upper ureteral calculi, ureteroscopic stone removal under intravenous propofol anesthesia can be performed safely and effectively without any significant increase in morbidity or patient discomfort.
