Background: Several previous studies have shown that snoring is associated with glucose metabolism and the development of diabetes, but rare study has shown the association between snoring frequency and prediabetes, particularly in China. We hypothesized that individuals who snore might have a higher risk of prediabetes. This study aimed to investigate the association between self-reported snoring and prediabetes in a Chinese population. Methods: A cross-sectional study was performed in three large communities of Beijing from December 2011 to August 2012 by recruiting individuals aged ≥40 years old. All participants were requested to complete a detailed questionnaire and undergo anthropometric measurements. A 75 g oral glucose tolerance test was performed in individuals without diabetes. Blood samples of all participants were collected; blood glucose and blood fat levels were measured. Multivariate logistic regression models were built to assess the association between snoring frequency and prediabetes. Results: A total of 13,592 participants (female: 66.56%; mean age: 56.8 ± 7.9 years; mean body mass index: 25.5 ± 3.4 kg/m2) were included in the final analysis. Of these, 30.9% were diagnosed with prediabetes, while 41.3% and 25.4% had occasional and habitual snoring, respectively. Habitual snoring was associated with an increased risk of prediabetes (odds ratio [OR]: 1.3, 95% confidence interval [CI]: 1.1–1.4, P< 0.001), after adjusting for diabetes and sleep-related confounders in the multivariable models. Habitual snoring was also associated with isolated impaired fasting glucose (IFG; OR: 1.3, 95% CI: 1.0–1.6; P< 0.001) and isolated impaired glucose tolerance (IGT; OR: 1.3, 95% CI: 1.2–1.5; P< 0.001), but not IFG + IGT (OR: 1.1, 95% CI: 0.9–1.4; P = 0.281). When stratified by total cholesterol (TC) levels, this association between habitual snoring and prediabetes was observed only in individuals with TC

Aim. To investigate incidental adrenal enlargement clinical characteristics and functional status and analyze functional lesion risk factors. Materials and Methods. This retrospective study included 578 patients with adrenal imaging features showing enlargement. Incidental adrenal enlargement cases (78) were considered eligible. Demographics, functional diagnosis, adrenal imaging features, and concomitant diseases were analyzed. Results. The number of adrenal enlargements and proportion of incidental adrenal enlargement increased each year. Mean patient age was 50.32 years. Thirty-nine cases had unilateral enlargement on the left side and 3 on the right side; 36 had bilateral enlargement. Routine medical checkup was found to have the greatest chance (43.59%) of revealing clinical onsets leading to discovery. Biochemical and functional evaluation revealed 54 (69.23%) cases of nonfunctional lesions, 12 (15.38%) of subclinical Cushing syndrome, 6 (7.69%) of primary hyperaldosteronism, 1 (1.28%) of metastasis, and 5 (6.41%) of unknown functional status. Nodular adrenal enlargement (OR, 7.306; 95% CI, 1.727–28.667; P = 0.006) was a risk factor for functional lesions. Age and lesion location were not significant factors. Conclusion. Incidental adrenal enlargement is a frequent radiographic finding and is accompanied by diverse clinical factors that require proper evaluation and management. Nodular adrenal enlargement was a risk factor.

Tumor-induced osteomalacia (TIO) is an extremely rare metabolic bone disease and the occult offending tumor arising in facies cranii is even more uncommon. In this report, we described 2 middle-aged females with TIO caused by the tumor in facies cranii, which had ever been misdiagnosed as rheumatoid arthritis. Case 1 was present with diffuse bone pain and muscle weakness for 4 years, as well as esotropia in the right eye for 1 month. Case 2 was present with progressive bone pain in low back and hip for 2 years. Biochemical studies both showed persistent hypophosphatemia and urinary over wasting phosphate. Radiological examinations revealed the infiltrative mass in right apex partis petrosae ossis temporalis in case 1, and the soft mass in left nasal cavity and ethmoid sinuses in case 2, respectively. The offending tumors were resected completely in case 2, however, incompletely in case 1. Pathology examination revealed mixed connective tissue variant phosphaturic mesenchymal tumors. In conclusion, TIO should be presumed in patients presenting with unexplained persistent hypophosphatemia osteomalacia, also a thorough detection for tumor in facies cranii should be performed.

Both ectopic pancreas and insulinoma are rare. A 21-year-old male patient had suffered from hypoglycemia episodes for 3 years and was diagnosed to have insulinoma based on biochemical and endocrinological evaluations. Various localization approaches revealed a distinct tumor outside the pancreas. With intraoperative endoscopy, the tumor in duodenohepatic ligament was identified and successfully resected. Pathologic evaluation revealed an ectopic insulinoma with ectopic pancreas. Therefore, when the biochemically confirmed insulinoma could not be well-definitely localized, the possibility of ectopic insulinoma should be suspected. In addition, radiography examinations and operation exploration should extend to the field where ectopic pancreas usually presents.
