The role of adiposity in the relationship between serum vitamin D levels and insulin resistance has not yet been fully studied. This aim of this study is to clarify the role of adiposity in the relationship between serum vitamin D level and insulin resistance among middle-aged and elderly Korean adults.


We used data from 2,710 individuals aged ≥50 years based on national data from a representative sample of the fourth Korea National Health and Nutrition Examination Survey IV-2 in 2008.


After adjustment for potential confounders, body mass index (BMI) was significantly associated with 25(OH) vitamin D (P=0.008). However, waist circumference was not significantly associated with 25(OH) vitamin D. In the stratified analyses, 25(OH) vitamin D was found to be negatively associated with fasting insulin and homeostasis model assessment estimate of insulin resistance (HOMA-IR) in participants with BMIs ≥25 kg/m2 (P=0.003 for both insulin and HOMR-IR) but was not found to be associated in those with BMIs <23 kg/m2. However, we observed a significant inverse in the association of 25(OH) vitamin D with fasting insulin and HOMA-IR in both the normal (P=0.001 and P<0.001 and the abdominally obese group (P=0.010 and P=0.009) in the stratified analyses according to abdominal obesity.


Our results support that the idea that endogenously-produced vitamin D might be stored in subcutaneous fat deposits. In addition, the association of vitamin D with insulin resistance in middle-aged and elderly Korean adults was stronger when it was stratified by BMI than when abdominal obesity status.

AbstractAbstract PDF
Whether thyroid lobectomy alone is a sufficient treatment for papillary thyroid microcarcinoma (PTMC) remains controversial. The aim of this study is to evaluate the predictive factors for incidental contralateral carcinoma in patients confirmed of unilateral PTMC preoperatively. METHODS: Between January 2007 and December 2009, 393 patients underwent thyroid surgery for unifocal and unilateral PTMC preoperatively at Pusan National University Hospital. A total thyroidectomy with central neck dissection was routinely performed for these patients during this study period. RESULTS: Among the 393 cases in the cohort, 77 patients (19.6%) had incidental PTMC in the contralateral lobe. In patients with incidental contralateral carcinoma, there was higher prevalence in extrathyroid extension, occult ipsilateral carcinoma, pathologic Hashimoto's thyroiditis, and central lymph node metastasis compared to those without contralateral carcinoma. The mean tumor size also increased in patients with contralateral carcinoma. Multivariate logistic regression showed that extrathyroid extension (P = 0.049), occult ipsilateral carcinoma (P < 0.001), pathologic Hashimoto's thyroiditis (P = 0.038), and central lymph node metastasis (P = 0.002) were predictive factors for incidental contralateral carcinoma. CONCLUSION: In conclusion, multifocality in the ipsilateral lobe, central lymph node metastasis, extrathyroid extension, and Hashimoto's thyroiditis is associated with the presence of contralateral carcinoma. Thus, if these factors are found by preoperative and/or postoperative evaluation, total thyroidectomy or completion thyroidectomy is necessary for the treatment of PTMC.

AbstractAbstract PDF
Metastases to the thyroid gland are not frequently observed in clinical practice, although an overall incidence of secondary thyroid malignant tumors has been reported to range from 1.25% to 24% in autopsy series. Generally, patients with metastatic thyroid cancer present with euthyroidism and they do not develop thyroid dysfunction. Thyroid dysfunctions, including hypothyroidism and hyperthyroidism, rarely occur in patients with metastatic thyroid cancer. We describe here a case of hypothyroidism induced by thyroid metastasis from cancer of an unknown primary site in a 53-year-old man and another case of thyrotoxicosis induced by thyroid metastasis from lung cancer in a 65-year-old man.
