- Background
Radiation exposure is a well-known risk factor for papillary thyroid cancer (PTC). South Korea has 24 nuclear reactors in operation; however, no molecular biological analysis has been performed on patients with PTC living near nuclear power plants.
Methods
We retrospectively included patients with PTC (n=512) divided into three groups according to their place of residence at the time of operation: inland areas (n=300), coastal areas far from nuclear power plants (n=134), and nuclear power plant areas (n=78). After propensity score matching (1:1:1) by age, sex, and surgical procedure, the frequency of representative driver mutations and gene expression profiles were compared (n=50 per group). Epithelial-mesenchymal transition (EMT), BRAF, thyroid differentiation, and radiation scores were calculated and compared.
Results
No significant difference was observed in clinicopathological characteristics, including radiation exposure history and the frequency of incidentally discovered thyroid cancer, among the three groups. BRAFV600E mutation was most frequently detected in the groups, with no difference among the three groups. Furthermore, gene expression profiles showed no statistically significant difference. EMT and BRAF scores were higher in our cohort than in cohorts from Chernobyl tissue bank and The Cancer Genome Atlas Thyroid Cancer; however, there was no difference according to the place of residence. Radiation scores were highest in the Chernobyl tissue bank but exhibited no difference according to the place of residence.
Conclusion
Differences in clinicopathological characteristics, frequency of representative driver mutations, and gene expression profiles were not observed according to patients’ region of residence in South Korea.

- Background
We analyzed hemoglobin A1c (HbA1c) levels and various lung function test results in healthy individuals after a 6-year follow-up period to explore the influence of lung function changes on glycemic control.
Methods
Subjects whose HbA1c levels did not qualify as diabetes mellitus (DM) and who had at least two consecutive lung function tests were selected among the people who visited a health promotion center. Lung function parameters, including forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV/FVC ratio, and forced expiratory flow 25% to 75% (FEF25%−75%), were divided into four groups based on their baseline quantiles. To evaluate future DM onset risk in relation to lung function changes, the correlation between baseline HbA1c levels and changes in lung function parameters after a 6-year follow-up period was analyzed.
Results
Overall, 17,568 individuals were included; 0.9% of the subjects were diagnosed with DM. The individuals included in the quartile with FEV1/FVC ratio values of 78% to 82% had lower risk of DM than those in the quartile with FEV1/FVC ratio values of ≥86% after adjusting for age, sex, and body mass index (P=0.04). Baseline percent predicted FEV1, FVC, FEV1/FVC ratio, and FEF25%−75%, and differences in the FEV1/FVC ratio or FEF25%−75%, showed negative linear correlations with baseline HbA1c levels.
Conclusion
Healthy subjects with FEV1/FVC ratio values between 78% and 82% had 40% lower risk for future DM. Smaller differences and lower baseline FEV1/FVC ratio or FEF25%−75% values were associated with higher baseline HbA1c levels. These findings suggest that airflow limitation affects systemic glucose control and that the FEV1/FVC ratio could be one of the factors predicting future DM risk in healthy individuals.

Abstract
PDF
- An increasing number of incidental adrenal masses are found during the evaluation for unrelated problems, which is the result of the development of sensitive noninvasive methods for the imaging of abdominal lesions, such as ultrasonography, computed tomographic scanning, and MRI. When there is no evidence of adrenocortical or medullary dysfunction for such adrenal masses, they are commonly referred to as "incidentalomas". Among these incidentalomas, adrenal myelolipoma is a rare, benign, endocrinologically inactive tumor, the histological structure of which consists of mature adipose tissue cells and normal hemopoietic tissues resembling bone marrow. Even though most eventually prove to be nonhyperfunctioning adrenocortical adenomas, we must not exclude a more serious pathology. Because of the rarity of adrenal myelolipoma, its natural history, proper prognostic considerations and treatment recommendations still need to be investigated. We experienced 46 year-old man with abdominal discomfort, and a 26 year-old man with no specific symptoms, have large incidentalomas (>5 cm) in adrenal sites, detected by abdominal sonography for routine health work-up. The ACTH, cortisol, renin, aldosterenone, metanephrine, VMA and tumor marker levels were normal, which was suggestive of nonfunctional adrenal tumors. Surgical treatments were performed for rule out malignant adrenal tumors due to the tumor size (>5 cm) and hemorrhage within the tumors. The surgical pathology was that of adrenal myelolipomas. An adrenal myelolipoma is a rare, benign, nonfunctional adrenal tumor, but only three cases have been reported in Korea. We report two cases of adrenal myelolipoma found incidentally by surgical treatment for a large tumor size (>5 cm).
