F-Fluorocholine PET/CT in Primary Hyperparathyroidism: Superior Diagnostic Performance to Conventional Scintigraphic Imaging for Localization of Hyperfunctioning Parathyroid Glands.

Primary hyperparathyroidism (PHPT) is a common endocrine disorder, definitive treatment usually requiring surgical removal of the offending parathyroid glands. To perform focused surgical approaches, it is necessary to localize all hyperfunctioning glands. The aim of the study was to compare the efficiency of established conventional scintigraphic imaging modalities with emerging F-fluorocholine PET/CT imaging in preoperative localization of hyperfunctioning parathyroid glands in a larger series of PHPT patients.

Superior Diagnostic Performance of the GLP-1 Receptor Agonist [Lys(AhxHYNIC-[Tc]/EDDA)NH]-Exendin-4 over Conventional Imaging Modalities for Localization of Insulinoma.

Purpose: Insulinomas are the most common functioning neuroendocrine neoplasms of the pancreas, typically diagnosed due to characteristic symptoms. In the vast majority, the treatment is surgical and curative, requiring accurate localization of the tumour; conventional imaging, including somatostatin receptor molecular imaging, is negative in up to 10 % of cases. Recently, labelled glucagon-like peptide receptor (GLP-1R) analogues were introduced as a sensitive diagnostic method for localization of insulinomas.

Burst fractures of the second through fifth lumbar vertebrae. Clinical and radiographic results.

Fifty-five patients who had sustained a burst fracture of the lumbar spine were followed for a mean of seventy-nine months (range, twenty-four to 192 months) after the injury. Thirty patients had been managed non-operatively with a short period of bed rest followed by protected mobilization. The remaining twenty-five patients had been managed operatively: eight, with posterior arthrodesis with long-segment hook-and-rod fixation; eight, with posterior arthrodesis with short-segment transpedicular fixation; six, with posterior arthrodesis and instrumentation followed by anterior decompression and arthrodesis; and three, with anterior decompression and arthrodesis.
