Sonographic Differentiation of Thyroid Nodules With Eggshell Calcifications

Objective. The purpose of this study was to assess the role of known suspicious sonographic findings and to find other additional sonographic findings to differentiate benign and malignant thyroid nodules with “eggshell” calcifications. Methods. Our Institutional Review Board approved this retrospective study, and informed consent was not required. We reviewed sonographic findings of thyroid nodules in 795 patients who underwent thyroid surgery in our institution between August 2006 and February 2007. Ninety‐three thyroid nodules with eggshell calcifications in 92 patients were included in this study. Each lesion was evaluated for known suspicious sonographic criteria, including marked hypoechogenicity, irregular or microlobulated margins, and a taller‐than‐wide shape, as well as 2 additional sonographic findings: a hypoechoic halo and disruption of eggshell calcifications (halo and disrupted calcification rim). The sensitivity and specificity based on the sonographic criteria were calculated and compared among the 2 types of criteria. Results. Among the 93 thyroid nodules, 59 were malignant and 34 were benign. The halo and disrupted calcification rim showed higher sensitivity (62.7% and 76.3%, respectively) than any of the known suspicious sonographic criteria (40.7%, 35.6%, and 55.9%). The combination of both the halo and the disrupted calcification rim showed significantly higher sensitivity (93.2%) than the combination of the known suspicious sonographic criteria (78%; P < .05), although both had the same specificity (64.7%). Conclusions. In thyroid nodules with eggshell calcifications but no other calcifications, the findings of a peripheral halo and disruption of the eggshell calcifications may be more useful sonographic predictors of malignancy than hypoechogenicity, microlobulated margins, and a taller‐than‐wide shape.     

Low-density lipoprotein subclass and its correlating factors in diabetics

OBJECTIVES: Small dense LDL, low density lipoprotein (LDL) particles with small size and high density, is regarded as a significant risk factor for cardiovascular diseases. Diabetes mellitus is one of the conditions accompanied by increased small dense LDL. We analyzed LDL subclass in type 2 diabetics and normal controls with LipoPrint LDL System to investigate the LDL heterogeneity in diabetics and factors affecting it. DESIGN AND METHODS: We selected 40 normal controls and 40 type 2 diabetics with fasting blood glucose level over 7.0 mmol/L and HbA1c level over 7%. LDL subclass was determined with LipoPrint LDL System. LipoPrint LDL System fractionates LDL into seven parts (LDL1-7) by size and LDL3 to LDL7 are defined as small-sized LDL. In addition we estimated 'the percent of small-sized LDL over whole LDL' and defined it as 'small-sized LDL proportion'. RESULTS: Mean small-sized LDL proportion was significantly higher in diabetics (23.4%) than in controls (11.8%) (p<0.001) and small-sized LDL proportion showed positive correlation with blood levels of glucose, HbA1c, total cholesterol, triglyceride, and oxidized LDL and negative correlation with HDL cholesterol level in univariate analysis (p<0.001). Of these parameters, triglyceride, HbA1c, oxidized LDL were statistically significant variables contributing to the small-sized LDL proportion in stepwise multiple regression analysis. CONCLUSIONS: We analyzed small-sized LDL proportion in type 2 diabetics and found that it was significantly increased in diabetics than control subjects and it was independently correlated with triglyceride, HbA1c, oxidized LDL in descending order, which are reflecting lipid metabolism, glycation, and oxidative stress, respectively.
