Unlabelled: THE AIM of this study is to evaluate the accuracy of scintigraphic preoperative localization of abnormal parathyroid gland.
Methods: 25 patients with confirmed hyperparathyroidism undergone scintigraphic and ultrasound localization prior to surgery. Paratthyroid scintigraphy was done with thallium - techetium substraction and technetium-tetrofosmin dual phase techniques.
Results: scintigraphic sensitivity and specificity was 83% and 100%. In primary hyperparathyroidism the sensitivity was 91% vs 75% in secondary one. Multinodular goiter affected sensitivity (72%). Ultrasound had an overall sensitivity of 66 % and a specificity of 100%.
Conclusion: parathyroid scintigraphy is non invasive, accurate and costeffective in localizing abnormal parathyroid gland especialy adenoma.

Ectopic parathyroid glands result from abnormal migration during development. If not detected promptly, they can lead to persistent or recurrent primary hyperparathyroidism (pHPT). Inferior parathyroid glands are typically located in the anterior mediastinum, while superior parathyroid glands are often near the tracheoesophageal groove, both of which contribute to pHPT.

Secondary hyperparathyroidism (sHPT) is a significant clinical complication of CKD leading to bone abnormalities and cardiovascular disease. Current treatment based on activating the parathyroid calcium-sensing receptor (CaSR) using calcimimetics such as Cinacalcet, aims to decrease plasma PTH levels and inhibit the progression of parathyroid hyperplasia. In the present study, we found significant diurnal rhythmicity of Casr, encoding the Cinacalcet drug target in hyperplastic parathyroid glands (p = 0.

Article Synopsis
- Uremic leontiasis ossia (ULO) is a rare condition linked to renal osteodystrophy in patients with end-stage chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPTH), causing bone deformities that can lead to a 'leonine' facial appearance.
- The case study focuses on a 39-year-old female patient undergoing treatment, who exhibited significant symptoms and had elevated parathyroid hormone (PTH) levels, confirmed by CT scans.
- Treatment involves a multidisciplinary approach including surgery and management of SHPTH to correct anatomical issues and prevent further complications.
Endocrine Care of a 19-year-old Woman With Isolated Hypogonadotropic Hypogonadism due to 4H Syndrome.

Background/objective: 4H syndrome is a rare form of leukodystrophy characterized by hypomyelination, hypodontia, and hypogonadotropic hypogonadism. In 95% of cases, hypomyelination is present, but other clinical features, such as hypodontia and hypogonadotropic hypogonadism, are not always present and may not be necessary for diagnosis. Hypogonadotropic hypogonadism is the most common endocrine complication that can occur in 4H syndrome.

Objective: Vitamin D deficiency (VDD) in children can cause hypocalcaemia and rickets, but the prevalence of these complications and the 25-hydroxyvitamin D (25OHD) concentrations below which they arise is uncertain. We investigated this in children (< 18 years) with 25OHD measurements.
Design, Measurement And Patients: We obtained 25OHD results from the regional laboratory database, alongside albumin-adjusted serum calcium (aCa), parathyroid hormone (PTH) and alkaline phosphatase (ALP) within 6 months of the index 25OHD.
