Simple or unicameral bone cysts are metaphyseal lesions of long bones. They usually move away from the physiswith growth to become diaphyseal in location. Involvement of the physis and epiphysis by these cystic lesions isvery rare. This paper reports a case of simple bone cyst of the proximal humerus in a 11- year -old girl which wasshown by MR imaging to extend through the physis into the epiphysis.

Sparganosis is a parasitic infectious disease by sparganum which is a plerocercoid larva of spirometra, a kind of cestode. We experienced a case of intramural sparganosis of cecum presenting as chronic intermittent abdominal pain. A 39 year old man was hospitalized due to intermittent abdominal pain for 6 months and the operation was done under the impreesion of the intestinal tuberculosis or submucosal tumor of cecum after diagnostic work-up. Resected cecum revealed diffuse wall thickening and luminal narrowing. The microscopic findings showed a degenerated larva in the muscle layer with typical tissue reaction which was basically noncaseating cavitary granulomatous inflammation and many calcareous corpuscles which were pathognomonic features of cestode were prominent within the degenerated worm.

BACKGROUND/AIMS: This study evaluated the clinicopathologic characteristics of patients with secondary appendiceal tumors (SATs). METHODS: We performed a single-center, retrospective study of patients with pathologically confirmed SATs. RESULTS: Among 180 cases of appendiceal malignancies diagnosed between 2000 and 2007, 139 cases (77.2%, 46 male) were SATs. The median age at SAT diagnosis was 55 years. The most common primary origin was the ovary. The mode of appendiceal involvement was metastasis in 122 and invasion in 17 patients. Extra-appendiceal involvement was present in 134 patients. The only manifestation that could be attributed to the SAT itself was appendicitis (n=8). Serosal involvement was predominant. The median survival after diagnosis of SAT was 22.6 months. In the Cox regression analysis, chemotherapy included in the treatment was the only factor associated with prolonged survival (hazards ratio, 0.12; 95% confidence interval, 0.06-0.23; p<0.001). Complete resection of the SAT had no influence on survival. CONCLUSIONS: SATs accounted for 77.2% of all pathologically diagnosed appendiceal malignancies. The most common origin was the ovary. SATs were usually associated with widespread disease, and the median survival after SAT diagnosis was 22.6 months. Complete resection of the SAT had no influence on survival.

The aim of this study was to report a single center experience of primary pancreatic lymphoma (PPL) in Korea. We analyzed the clinicopathological data from four PPL patients (three male, median age 36 yr) diagnosed from 1997 to 2007 at Seoul National University Hospital. The diagnoses were: diffuse large B cell lymphoma (n=2), Ki-1 (+) anaplastic large cell lymphoma (n=1), and Burkitt lymphoma (n=1). Presenting symptoms and signs were: abdominal pain (n=4), pancreatitis (n=2), weight loss (n=2) and abdominal mass (n=1). No patient underwent surgery. The Ann Arbor stages of the patients were: IEA (n=1), IIEA (n=1), and IVEB (n=2). Two patients underwent treatment. The stage IEA patient underwent chemotherapy and radiation therapy that resulted in a complete remission. The stage IVEB patient who underwent chemotherapy relapsed. This patient underwent subsequent peripheral blood stem cell transplantation and is alive at 30 months. Two patients (stages IVEB and IIEA) without treatment died at 0.8 and 7.0 months, respectively. For PPL patients, chemotherapy-based treatment, and addition of radiation therapy, if possible, may offer good prognosis.

BACKGROUND: Perfusion scans are accurate predictors of postoperative lung function. There are few previous studies aimed at predicting the postoperative exercise capacity using the perfusion scanning and those that did reported contradictory results. METHOD: We prospectively studied the preoperative spirometric, exercise tests and perfusion scans from in 49 consecutive patients who were admitted to Inha University Hospital with surgically resectable lung cancer from Jan. 1998 to Jun. 1999 29 patients who had any condition affecting the lung function and exercise capacity, or refused a surgical resection or a follow-up study were excluded. Spirometric and exercise tests were performed 6 months after operation in 20 patients. RESULTS: The predicted postoperative FEV1, FVC and TLC correlated well with the following corresponding postoperative values : γs and p value, 0.809 and 0.000 for the FEV1 ; 0.895 and 0.000 for the FVC ; 0.741 and 0.006 for the TLC, respectively. The measured postoperative exercise values were slightly higher than the postoperative exercise values predicted, VO(2max) and Wr(max), were as 112% of VO(2max) predicted and 119% of WR(max) predicted. The change in FEV1, FVC and TLC had a weak correlation with the change in VO(2max) and WR(max). CONCLUSION: The perfusion scan was a useful tool for predicting the postoperative exercise capacity. However, they had a tendency to underestimate the exercise capacity, especially in the patients who had a pneumonectomy. A weak correlation between the change in lung function and exercise capacity was obseved.

BACKGROUND AND OBJECTIVES: Obesity is a cause of cardiac dysfunction. We analyzed the change of diastolic function with the increase of the body mass index (BMI) for the early detection of cardiac dysfunction in overweight and obese patients. To analyze the diastolic function, we measured the mitral valve early and late diastolic inflow velocities with performing Doppler studies (E, A) and the early and late mitral annulus velocities with performing tissue Doppler studies (E', A'). SUBJECTS AND METHODS: From January 2005 to October 2007, 2,684 cases were enrolled in this study. The patients had a normal cardiac size, normal systolic function, no regional wall motion abnormalities and no significant valve disease. Those patients with a history of congenital heart disease, renal failure and congestive heart failure were excluded. The BMI was checked and Doppler echocardiographic analysis, including tissue Doppler, was done. RESULTS: The left ventricle (LV) mass index (normal: 89.1+/-19.1, overweight: 95.7+/-18.4, obese: 97.2+/-18.9 g/m2, p<0.01), and the E/E' (8.84+/-2.81, 10.02+/-3.03, 10.84+/-3.66, respectively, p<0.01) were higher, and the E (72.4+/-16.7, 68.6+/-16.0, 71.5+/-17.0 cm/sec, respectively, p<0.01), and E' (8.78+/-2.77, 7.27+/-2.19, 7.17+/-2.62 cm/sec, respectively, p<0.01) were lower in the overweight (BMI> or =25 kg/m2) and obese groups (BMI> or =30 kg/m2) than that of the normal group. On multiple logistic regression analysis, overweight was an independent risk factor for diastolic dysfunction with considering other risk factors such as hypertension, diabetes mellitus, age and gender. The risk of LV diastolic dysfunction was increased 2.13 times in the overweight group and 3.1 times in the obese group as compared with the normal group. CONCLUSION: With an increase of weight, diastolic function was worsened before the development of systolic dysfunction. This change was apparent in the overweight group. Tissue Doppler study on the mitral annulus is more sensitive to detect the change of diastolic function in overweight and obese patients.
