RESUMEN

PURPOSE: Besides typical clinical symptoms, primary hyperparathyroidism (pHPT) is associated with impaired quality of life and cognitive status. The aim of this study was to evaluate the quality of life and cognitive impairment in patients with pHPT, before and after parathyroidectomy. METHODS: We conducted a panel study, which included asymptomatic pHPT patients scheduled for parathyroidectomy. Besides demographic and clinical data, patients' quality of life and cognitive capacity were recorded before, 1 month, and 6 months following parathyroidectomy using the Short Form 36 questionnaire (RAND-36), Beck Depression Inventory (BDI), Depression Anxiety Stress Scales (DASS), Mini-Mental State Examination (MMSE), and Symptom Check List 90-revised version (SCL90R). RESULTS: During a 2-year follow-up, 101 patients entered the study (88 women), with an average age of 60.7 years. The Global score of RAND-36 test ameliorated by almost 50% 6 months after parathyroidectomy. The most sustained subscores of the RAND-36 test were role functioning/physical and health change, with an improvement of more than 125%. According to the BDI, DASS depression subscore, and SCL90R depression subscore, the extent of depressive symptoms reduction was approximately 60% 6 months postoperatively. The level of anxiety was reduced by 62.4%, measured by both the DASS and SCL90R anxiety subscores. The stress level was almost halved according to the DASS stress subscore (from 10.7 to 5.6 points). The results of the MMSE test showed a significant improvement postoperatively, for 1.2 points (4.4%). A worse preoperative score of each tool was related to the higher magnitude of improvement 6 months after parathyroidectomy. CONCLUSION: A considerable number of pHPT patients, even without other typical symptoms, show signs of impaired quality of life and neurocognitive status preoperatively. After a successful parathyroidectomy, there is an improvement in quality of life, declined levels of depression, anxiety, and stress, as well as amelioration of cognitive status. Patients with more impaired quality of life and pronounced neurocognitive symptoms may expect more benefits from the surgery.

RESUMEN

BACKGROUND: Apart from being a rare endocrine tumor, parathyroid carcinoma is also one of the rarest malignancies in human beings. Parathyroid carcinoma is even more uncommon in haemodialysis patients with end-stage renal disease. The pathogenesis of parathyroid hyperplasia in haemodialysis patients is well known, but the mechanism of development of parathyroid carcinoma in these patients remains unclear. METHODS: Three cases of parathyroid carcinoma in haemodialysis patients are presented in this study: a 69-year-old male patient and two female patients (67 and 61 years old). In all cases parathyroid carcinoma infiltrated the ipsilateral thyroid lobe and in one patient the right laryngeal nerve was involved as well. One patient underwent three surgical procedures. RESULTS: After surgical treatment, all patients were normocalcaemic and showed a significant reduction in PTH levels. CONCLUSION: In patients with secondary hyperparathyroidism, who develop parathyroid carcinoma, surgical resection is the only viable treatment option.

RESUMEN

Ectopic thyroid tissue is a rare pathological finding bellow the diaphragm and extremely rare finding is ectopic thyroid tissue in the adrenal gland (ETTAG). Thyroid tissue can be located anywhere along the way of embryological migration pathway of thyroglossal duct. In most cases of ectopic thyroid tissue, it is located in the neck. Here we present a case of 29 years old patient that was laparoscopically operated because of adrenal incidentaloma which showed 28 mm in maximal diameter on MRI. The patient had normal adrenal function. Pathohistological finding confirmed ETTAG. Follicular cells express TTF-1, Thyroglobulin, PAX8, and cytokeratin 7, and lack expression of calretinin. This is the 15th such case described in literature. Women are much more affected than men (14:1), and it usually presents in the fifth decade (mean age 49). In all cases ETTAG was composed of normal follicular cells, and C cells were not found. Review of the literature reveals that adrenal ectopic thyroid tissue is almost always cystic, and has distinctive pathologic features. The most important thing is that ETTAG must be distinguished from metastatic deposits from thyroid gland carcinoma. Our patient had normal thyroid function, without any nodules in thyroid gland. We report the youngest patient with ectopic thyroid tissue located in the adrenal gland.
