Multi-slice Spiral CT Features of Struma Ovarii / 中国医学影像学杂志

PurposeStruma ovarii (SO) is rare and has no typical symptoms, which is likely to be misdiagnosed before procure. The present study aimed to evaluate multi-sliced CT (MSCT) findings of struma ovarii so as to improve its imaging diagnosis.Materials and Methods The clinical and radiological data of 25 patients with struma ovarii confirmed pathologically patients were retrospectively analyzed and further compared with the pathological results after procure.Results For 25 SO patients, 22 (88%) had unilateral lesions and the rest 3 (12%) had bilateral ones; 11 lesions (44%) were cystic, 8 lesions (32%) were cystic-solid, and 6 lesions (24%) were solid. The CT images of 8 lesions showed high density cystic lumens. Twenty-five tumors had smooth margins, which appeared round, ellipse or irregular. The pathological findings showed that most of the cystic portions were filled with high proteinaceous gelatinous fluid and eosinophiclic colloid, and the solid portions consisted of thyroid tissue and stoma containing abundant blood vessels and fibrous tissue.Conclusion SO has the MSCT features such as cystic solid mass with unilateral and smooth margin, capsular space with high density, calcification, and solid parts with obvious enhancement.

Peritoneal protein losses, a novel predictor of cardiovascular diseases in patients on continuous ambulatory peritoneal dialysis / 中华肾脏病杂志

Objective To study the relationship between cardiovascular diseases (CVD)and 24-h peritoneal protein losses (PPL) in continuous ambulatory peritoneal dialysis (CAPD)patients. Methods One hundred and seventy-eight CAPD patients in our department were enrolled in this study. Their 24-h PPL was measured and other clinical data were recorded at the beginning. Meanwhile, Doppler ultrasound examination was performed. They were then followed-up prospectively for the development of CVD. Results The average of 24-h PPL was (5.0±1.8) g.Patients with diabetic status or preexisting CVD or carotid arteries arteriosclerosis had higher 24-h PPL than those without (t=2.082, P=0.039; t=2.601, P=0.010; t=2.217, P=0.029). 24-h PPL was positively correlated with left ventricular end-diastolic diameter (LVDd), interventricular septal thickness (IVSTd), posterior wall diameter of left ventricle at end-diastolic (LVPWd) and left ventricular mass index (LVMI) (r=0.222, P=0.040; r=0.217, P=0.043; r=0.339, P=0.002; r=0.305, P=0.007). It was negatively correlated with ejection fraction of left ventricle (r=0.221, P=0.040). One hundred and fourteen CAPD patients were prospectively followed-up for at least twelve months. Patients developing CVD were 40.4% and 19.3% for high and low PPL groups respectively (x2=6.035, P=0.014). In the multivariable logistic regression analysis, the 24-h PPL was one of the independent factors for developing CVD. Conclusions There is a significant and independent relationship between 24-h PPL and new cardiovascular events. 24-h PPL may be an important predictor of cardiovascular disease.
