Introduction: Increased B12 deficiency among T2DM patients using metformin has been reported. Holotranscobalamin (HoloTc), the bioactive form of B12, is proposed as a specific and sensitive marker of B12 deficiency. Methods to evaluate vitamin B12 deficiency in these patients remain controversial.Methods: First, we studied the prevalence of vitamin B12 deficiency in a group of 106 T2DM patients treated by Metformin, not supplemented by B12. Antacids were...

Introduction: Parathyroid carcinoma (PCa) is a rare presentation of primary hyperparathyroidism (PHPT), accounting for less than 1% of cases. Differentiating parathyroid cancer from benign hyperparathyroidism is clinically challenging. Some previous work suggest that there is a paraneoplastic hCG production in parathyroid cancer (Stock et al 1987, Rubin et al 2008). In this study, we aimed to investigate whether the hCG+β kit from Roche Diagnostics could distinguish PCa p...

Background: Parathyroid carcinoma (PCa) is a rare disease that can be difficult to differentiate initially from benign parathyroid adenoma. PCa over-secrete the amino form of parathyroid hormone (PTH), which is recognized by 3rd generation but not by 2nd generation (‘intact’) PTH assays. In normal individuals, the 3rd generation/2nd generation PTH ratio should always be <1.Material and methods: We studied the utility of the 3rd generation/2...

Objective: Long-term androgen deprivation therapy (ADT) negatively influences bone. The short-term effects on bone and mineral homeostasis are less known. Therefore, we aimed to investigate the early effects of ADT on calcium/phosphate homeostasis and bone turnover.Design: Prospective cohort study.Methods: Eugonadal adult male sex offenders, who were referred for ADT to the endocrine outpatient clinic, received cyproterone acetate....
