Background: The aim of this study was to evaluate the influence of patient and adenoma characteristics on (99m)Tc-methoxy isobutyl isonitrile (MIBI) scan performance in individuals diagnosed with primary hyperparathyroidism (PHP).
Methods: Records of patients undergoing parathyroidectomy for PHP over 6 years at a single center were reviewed.
Results: The overall true-positive (TP) rate for (99m)Tc-MIBI scans was 56%. Adenomas sized 1.9 to 3.5 cm were more likely to have TP scans than 0.3-cm to 1.8-cm adenomas (74% vs 40%, P < .001). Preoperative ionized calcium levels between 1.49 and 1.72 mmol/L were more likely to have TPs than levels between 1.27 and 1.48 mmol/L (65% vs 47%, P < .05). No single class of medication was shown to significantly effect TP rates. A decrease in TP rate was observed for larger adenomas in patients on >or=1 medication (74% vs 65%, P = .05).
Conclusions: In PHP, (99m)Tc-MIBI scan positivity is most related to adenoma size and preoperative ionized calcium level.

Background: Primary hyperparathyroidism (PHPT) with mild hypercalcemia (Ca <12 mg/dL) often remains asymptomatic. However, PHPT may induce various psychiatric symptoms, including depression, cognitive dysfunction, and infrequently, psychotic symptoms, predominantly in older adults rather than in middle-aged or younger individuals.
Case‐presentation: A 48-year-old man, with no history of physical or mental illness, experienced delusions about a suspicious car in his neighborhood, believing it was linked to criminal activity.
Comparison of thermal ablation and surgery for hyperparathyroidism: a meta-analysis.

Objective: Surgery and thermal ablation are both viable treatment modalities for patients diagnosed with hyperparathyroidism (HPT). However, the comparative efficacy of these approaches remains uncertain. The objective of this meta-analysis is to evaluate the effectiveness of surgical complications and therapeutic strategies in managing HPT.

The prevalence of diseases accompanied by calcium metabolism disorders varies from low to moderate. For example, primary hyperparathyroidism, as one of the most common causes of pathological changes in calcium metabolism due to parathyroid hormone hypersecretion, occurs with a frequency of 85 to 233 cases per 100 thousand people.

Calcium is the most abundant mineral in the human body. About 99% of calcium is deposited in the bones in the form of hydroxyapatite and only 1% is located in the intracellular and extracellular fluid. Ionized calcium, which makes up about 50% of the total amount of circulating calcium, is biologically active; the remaining percentage is bound to plasma proteins (40%, of which albumin accounts for 90%, and globulins for 10%), or is in complex with anions (10%) such as citrate, lactate, bicarbonate, phosphate.

Hyperparathyroidism-jaw tumor syndrome (HPT-JT) is a rare hereditary disorder caused by pathogenic gene variants. We report the case of a patient with HPT-JT who carried a novel germline pathogenic variant. A 27-year-old woman presented with thirst, polyuria, fatigue, constipation, and a history of fibro-osseous mandible lesions and endometrial polyps.
