Prevalence of anti-neutrophil cytoplasmic antibody-associated vasculitis in the south of France, using the capture-recapture method.

Objectives: This study aimed to estimate the prevalence of ANCA-associated vasculitis (AAV). That is, granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA), in Southern France in 2018, and evaluate differences among Europeans and non-Europeans.

Methods: This population-based, cross-sectional study used four sources (hospitals, community-based physicians, laboratories, National Health Insurance) to identify adults ≥15 years diagnosed with GPA, MPA or EGPA, living in Hérault and Gard in 2018.

Parathyroid Hormone Assays following Total Thyroidectomy: Is There a Predictive Value?

Objectives: Parathyroid hormone (PTH) is a risk marker for hypoparathyroidism (hypoPTH). This study aimed to determine the predictive values of early PTH assays carried out at the moment of skin closure (PTH SC), to establish a treatment algorithm, identifying two threshold values. We assessed the reproducibility of this approach with two different immunoassay kits (hypoPTH) after total thyroidectomy, but its practical application is not consensual.

Robotic thyroid surgery: our experience with the infraclavicular approach.

Background: Robot-assisted endoscopic transaxillary thyroidectomy is an emerging surgical technique. Despite promising results it presents some limitations and remains controversial in terms of usefulness and validity. We developed an alternative robotic technique using a gasless infraclavicular approach.

The use of preoperative routine measurement of basal serum thyrocalcitonin in candidates for thyroidectomy due to nodular thyroid disorders: results from 2733 consecutive patients.

Context: The preoperative routine measurement of basal serum thyrocalcitonin (CT) in candidates for thyroidectomy due to thyroid nodules is currently a subject of debate.

Objective: The objective of this study was to evaluate the role of systematic basal serum CT measurement in improving the diagnosis and surgical treatment of medullary thyroid carcinoma (MTC) in patients undergoing thyroidectomy for nodular thyroid disorders, regardless of preoperative CT levels.

Design: We determined basal serum CT levels in 2733 consecutive patients before thyroid surgery and performed a pentagastrin test in patients with hypercalcitoninemia.

Updated definition of level VI lymph node classification in the neck.

Conclusion: This update will enable us to precisely address the involvement pattern of level VI and to standardize treatment procedures in order to refine their indications and eventually improve their results and avoid treatment morbidity.

Background: The neck level classification is being used worldwide to describe the lymph nodes status of the neck. It provides standardized data to properly evaluate and then improve our protocols for the management of neck metastasis in an evidence-based medical manner.
