BACKGROUND: Persistent postoperative elevation of parathyroid hormone (POePTH) following successful parathyroidectomy for primary hyperparathyroidism (PHPT) is presumed to result from bone remineralization. Predicting which patients may need treatment is difficult. This study investigated whether preoperative serum osteocalcin (OC), a bone turnover marker involved in mineralization, can predict POePTH. METHODS: A ...

WHO grade II glioma, i.e. diffuse low-grade glioma, is a pre-malignant tumour, usually revealed by seizures in young patients with a normal life. This tumour has a constant growth, and will inescapably become anaplastic. Surgical resection significantly increases the overall survival by delaying the malignant transformation. Thus, the dilemma is ...
