- Central diabetes insipidus is a heterogeneous condition that is characterized by polyuria and polydipsia, and this is due to a deficiency of arginine vasopressin. Central diabetes insipidus is rare in children and young adults, and up to 50 percent of cases are idiopathic. Genetic abnormalities in the homeobox genes have recently been shown, on sellar magnetic resonance imaging, to be associated with combined pituitary hormone deficiency with pituitary defect. We report here on a 44-year-old female who suffered from polydipsia, polyuria and primary amenorrhea since childhood. She was diagnosed with idiopathic central diabetes insipidus together with primary empty sella and combined pituitary hormone deficiency. On the genetic analysis, she was proven to have a point mutation of the PROP-1 gene, which is known as a cause of combined pituitary hormone deficiency.

- BACKGROUND
The accurate diagnosis of a thyroid nodule is important in deciding a patient's treatment plan and for predicting the prognosis. The histopathological diagnosis of resected specimens are largely positively accomplished, but the consistency of the diagnosis is low when the specimen shows a small carcinomatous cytological feature or the nodule does not express papillary proliferation. Therefore, the need for supplementary diagnostic measures is increased. Herein, the expressions of galectin-3 and thyroid peroxidase (TPO) of resected specimens were investigated using immunohistochemical staining, and their potential for contributing to an accurate diagnosis studied. METHODS: The specimens included 195 resected thyroid nodules obtained from 179 patients having undergone thyroid surgery. Immunohistochemical staining for two useful antibodies, galectin-3 and TPO, were performed, and the expressions of these two antibodies investigated with regard to the histological diagnosis. RESULTS: The sensitivity, specificity, and positive and negative predictive values of galectin-3 and TPO for detecting papillary carcinomas were all 100%, but these values were low for other forms of carcinoma. CONCLUSION: Our data showed the diagnosis of thyroid nodules, using immunohistochemical staining for galectin-3 and TPO, was very useful for detecting thyroid papillary carcinoma, but insufficiently sensitive for follicular carcinoma. Immunohistochemical staining for TPO is also useful for distinguishing cases when a false positive result for galectin-3 is obtained.
