Reoperation for persistent or recurrent secondary hyperparathyroidism

2017

Background: Secondary hyperparathyroidism is a common acquired disorder seen in chronic renal failure. Its pathophysiology is mainly due to hyperphosphatemia and vitamin D deficiency and resistance. When medical treatment fails, subtotal and total parathyroidectomy with autotransplantation are the standard procedures, although both are associated with high recurrence rates.Methods and Results: 4 patients experienced persistence and 9 relapse. The first 4 were subjected to reoperation after 6 months for the persistence of symptoms due to the finding of a supernumerary adenomatous gland while the remaining patients at the reoperation showed in 5 cases 2 more glands in over thymic position, an…

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…

Calciphylaxie : une complication grave et méconnue de l'insuffisance rénale chronique terminale. À propos de deux cas

2005

Calciphylaxis presents like subcutaneous lesions with livedo reticularis leading to necrotic and painful ulcers, predominantly in the lower limbs and the abdomen. They initially simulate dermohypodermitis. Biology reveals secondary hyperparathyroidism, phosphocalcic metabolism abnormalities and state of hypercoagulability. Histological signs are constant: calcifications in the media of small and sub-cutaneous arteries, intimal hyperplasia and intravascular thrombosis. This complication occurs in 4% of end-stage renal disease patients. Its prognostic is awful with a rate of mortality of 60% due to sepsis. Treatment is based upon the normalization of phosphocalcic rates and local debridement.

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.

Multiple brown tumours of tertiary hyperparathyroidism in a renal transplant recipient: : a case report

2010

Tertiary Hyperparathyroidism (HPT) is an uncommon condition that affects patients with secondary HPT after a successful kidney transplant. Bone alterations are the main consequences of this endocrine condition, including the development of an osteolytic lesion called brown tumour. This paper reports an unusual case of multiple brown tumours located in the maxilla and mandible in a 58-year-old renal transplant recipient, with tertiary HPT. Incisional biopsies were performed and, in both samples, the histopathological diagnoses were giant cell lesions. Due to these diagnoses, the medical history of chronic renal failure, and high levels of serum calcium and PTH, lesions were diagnosed as mult…

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.

Association of low 25-hydroxyvitamin D concentrations with elevated parathyroid hormone concentrations and low cortical bone density in early puberta…

2003

Background: Very few studies have evaluated both parathyroid hormone (PTH) and 25-hydroxyvitamin D [25(OH)D] and their effects on bone mass in children. Objective: We studied the associations of serum 25(OH)D and intact PTH (iPTH) with bone mineral content (BMC) and bone mineral density (BMD) at different bone sites and the relation between serum 25(OH)D and iPTH in early pubertal and prepubertal Finnish girls. Design: The subjects were 10‐12-y-old girls (n = 193) at Tanner stage 1 or 2, who reported a mean (± SD) dietary calcium intake of 733 ± 288 mg/d. 25(OH)D, iPTH, tartrate-resistant acid phosphatase 5b (TRAP 5b), urinary calcium excretion, BMC, areal BMD, and volumetric BMD were asses…

Simultaneous chronic rupture of quadriceps tendon and contra-lateral patellar tendon in a patient affected by tertiary hyperparatiroidism

2007

Abstract Spontaneous ruptures of the extensor mechanism of the knee are very rare. They tend to increase considerably in patients with metabolic diseases such as chronic renal failure, hyperparathyroidism, diabetes, gout, and systemic lupus erythematosus. The reported case regards a 48-year-old man with chronic, spontaneous and simultaneous quadriceps, and contra-lateral patellar tendon rupture. The patient suffered from chronic renal failure and for the past year from tertiary hyperparathyroidism. Ruptured tendons were repaired and both knee were evaluated monthly for the next 12 months. Good functional recovery was achieved on both knees without relapse. This case emphasizes the importanc…
