Primary aldosteronism (PA) is a major cause of secondary hypertension. Among PA, the diagnosis of an aldosterone-producing adenoma (APA) is critical because an APA can be cured surgically. Adrenal venous sampling (AVS) is the golden standard test in the diagnosis of an APA, but is available only in specialized medical centers. Meanwhile, aldosterone secretion of an APA is reported to be more sensitive to ACTH than that of idiopathic hyperaldosteronism (IHA) or essential hypert...

Tracheomalasia is extremely rare condition in Graves’ disease and may result in pneumomediastium with fistular formation from longstanding compression by a large goiter. There is no report that Graves’ disease combined with tracheomalasia and pneumomediastinum. A 24-year-old woman presented with abdominal pain, diarrhea and fever. On physical examination, a large goiter was detected on her anterior neck. Computed tomography of chest showed large amount of air in ante...

Atypical manifestations of hyperthyroidism include hematological, cardiovascular, dermatological manifestation. Especially single lineage abnormalities such as anemia (34%), leukopenia (5.8%), thrombocytopenia (3.3%) are reported, but pancytopenia is a rare presentation of hyperthyroidism. The suspected etiologic mechanisms include ineffective hematopoiesis, reduction in blood cell life span, autoimmune process, toxicity of thyroid hormone.We report a ca...

Osterix (Osx) is an essential transcription factor for osteoblast differentiation and bone formation. Osx null mutants died perinatally with a complete absence of bone formation and Osx conditional knockouts in osteoblasts showed the osteopenic phenotype after birth. Even in Osx heterozygous mice with normal bone morphology, the reduced cortical thickness and osteoblast differentiation were observed by QCT and in vitro cell culture, respectively. This result exhibited t...

Backgroud: The association with daily calcium intake and sarcopenia has not been well established.Objective: The objective was to assess the associate of daily calcium intake and sarcopenia.Methods: We analysed the fourth Korea National Health and Nutrition Examination Survey (KNHANES) in old adult (over 50 years), conducted in 2009.

Aims: Nonalcoholic fatty liver disease (NAFLD) is reported to contribute to the development of type 2 diabetes, but it is largely unknown whether such a relationship between NAFLD and incident diabetes relates to the severity of NAFLD or it is independent. We aimed to evaluate the association of the severity of NAFLD with development of type 2 diabetes in a retrospective cohort of Korean subjects.Methods: This study included 7,849 individuals without dia...
