Prediction of bone mass gain by bone turnover parameters after parathyroidectomy for primary hyperparathyroidism: neural network software statistical…
2006
Background Primary hyperparathyroidism (pHPT) is the most frequent endocrine hypersecretion disease, and parathyroidectomy is the only curative option, since pharmacologic therapy reduces hypercalcemia but does not impede parathyroid hormone hypersecretion. According to guidelines from the National Institutes of Health, parathyroidectomy is associated with bone mass increase in some asymptomatic patients, while in others bone mass is not changed after surgery. Therefore, we performed the present study in an attempt to elucidate whether a preoperative biochemical bone parameter can be predictive of a significant vertebral bone mass increase in patients with pHPT. Methods For each patient we …
Chronic asthenia in patients who have undergone endocrine neck surgery.
2021
Introduction: The impact of chronic asthenia after thyroidectomy has been evaluated in two previous studies comparing total thyroidectomy and hemithyroidectomy. We compared its impact on patients undergoing thyroidectomy, parathyroidectomy for primary hyperparathyroidism, and cholecystectomy. Methods: Patients recruited for surgery (233 consecutive total thyroidectomies for non-toxic multinodular goiter, Group I, 43 consecutive parathyroidectomies for primary hyperparathyroidism, group II and a sample of 43 laparoscopic cholecystectomies, group III) were compared at three times: pre-operative, 6 months after surgery, 1 year after surgery. A brief fatigue inventory (BFI) was administered to …
The Effect of High Parathyroid Hormone Concentration on Calcitonin in Patients with Primary Hyperparathyroidism2)
2009
Serum calcitonin (CT), parathyroid hormone (PTH), and calcium levels were measured in 23 patients with primary hyperparathyroidism. PTH was determined by a midregion (M-RIA) and a carboxyl-terminal (C-RIA) specific PTH-RIA. Only 2 patients had elevated CT levels. In contrast to the findings in 46 healthy controls, the CT levels did not correlate with calcium levels. Patients who had the highest iPTH values showed a negative correlation between CT and iPTH (M-RIA (n = 7): R = -1.0000, p less than 0.001; C-RIA (n = 13): R = -0.5604, p less than 0.05). The results of the C-RIA were subtracted from those of the M-RIA. In 12 patients with the highest levels of intact PTH (M-RIA - C-RIA), serum P…
Effekt von Calcium und Magnesium auf die Parathormonfreisetzung aus humanem Parathyreoidea-Gewebe in vitro
1982
The effects of calcium and magnesium on parathyroid hormone release from eight adenomas causing primary hyperparathyroidism and six hyperplastic glands causing hypercalcemic secondary hyperparathyroidism were investigated in vitro using single cell suspensions from the respective tissue. We observed suppression of parathyroid hormone release with increasing concentrations of either cation. The quantitative hormone secretions of both adenomatous and hyperplastic glands was identical.
Ergebnisse der bilateralen Operationstechnik bei primärem Hyperparathyreoidismus
2001
AIM OF THE STUDY The surgical success rate and clinical outcome after surgery for primary hyperparathyroidism were evaluated in a prospective long-term follow-up study. PATIENTS AND METHODS 407 patients, 396 with the first manifestation, 6 with recurrent and 5 with persistent disease underwent operation from August 1, 1987 to August 15, 1999. All patients were prospectively investigated in a long-term follow-up study and underwent reexaminations at regular surveillance intervals. The postoperative course is known in 93.9% of all patients. RESULTS The prevalence of asymptomatic primary hyperparathyroidism was 5.6% in our patients. Surgical cure was obtained in 97.7% of patients after initial…
Operative Therapie des primären Hyperparathyroidismus im Neugeborenenalter
1988
This is a report on a neonatal primary hyperparathyroidism (NPHPT) treated by total parathyroidectomy and autotransplantation of parathyroid tissue into the forearm musculature. Histologically, the glands were composed of a "chief cell hyperplasia" of the parathyroid tissue. Clinical manifestation in neonates and differential diagnosis of HPT are discussed. Indication for operation and surgical procedure are described.
