Hypercalcium crisis and postoperative hungry bone syndrome caused by primary hyperparathyroidism: a case report / 临床耳鼻咽喉头颈外科杂志

To review the diagnosis and treatment of a case of hypercalcium crisis caused by primary hyperparathyroidism（PHPT） and prophylactic treatment of hungry bone syndrome. In a 32-year-old male with hypercalcemia, the main manifestations were loss of appetite, nausea, polyuria, polydipsia, fatigue, lethargy, etc. parathyroid hormone, serum calcium increased, thyroid function was normal, thyroid color ultrasound and MRI showed space-occupying behind the right thyroid, radionuclide examination showed abnormal imaging agent concentration in the right parathyroid area, there was a history of pathological fracture. Clinically diagnosed as hypercalcemia crisis secondary to PHPT.

Correlation of 18F-NaF micro-PET/CT and score with histopathology in collagen-induced arthritis rats / 中国介入影像与治疗学

Objective To explore the correlation between 18F-NaF micro-PET/CT,μCT score and histopathology of collagen-induced arthritis (CIA) rats.Methods Seventy healthy female SD rats were randomized into CIA group (n＝50) and control group (n ＝ 20).Micro-PET/CT imaging was performed 10 days after successful modeling.Minimum standardized uptake value (SUVmin),maximum standardized uptake value (SUVmax),mean standardized uptake value (SUVmean) and μCT score were measured,and the severity of rheumatoid arthritis was assessed with histopathology.The correlations between SUVmin,SUVmax,SUV μCT score and histopathology of CIA were analyzed.Results SUVmin,SUVmax,SUVmean,μCT score of CIA all showed positive correlations with histopathology (r＝ 0.920,0.943,0.923,0.768,all P＜0.001).Conclusion 18F-NaF micro-PET/CT is a quantitative imaging method for evaluating bone erosion and bone malformation in rat rheumatoid arthritis models of CIA,which is superior to μCT examination.
