Hypoparathyroidism, Quality of Life
Conditions
Brief summary
Persistent hypoparathyroidism is an underestimate but major complication of total thyroidectomy. The hypothesis of the investigators is that the mental health is impaired in hypoparathyroid patients compared with thyroidectomized patients without hypoparathyroidism. The investigators evaluated the quality of life using the SF-36 survey in comparison with a control population of patients thyroidectomized but free from this complication. The voice quality, the cardiovascular risk, the kidney function and the incidence of urinary lithiasis were also evaluated.
Detailed description
Persistent hypoparathyroidism is an underestimate but major complication of total thyroidectomy. In this retrospective, observational, multicentre study, the investigators evaluated the quality of life using the SF-36 survey in comparison with a control population of patients thyroidectomized but free from this complication. Patients in six centers in France (Angers, Le Mans, Limoges, Nancy, Nantes, la Pitié-Salpétrière) and in the association Hypoparathyroïdisme France were contacted by mail. The primary endpoint was the mental health. The physic and global quality of life scores were assessed as secondary endpoints. Medical and VHI surveys were also send to the patients. The voice quality, the cardiovascular risk, the kidney function and the incidence of urinary lithiasis were also evaluated.
