Background: We aimed to investigate the association of preoperative calcium and parathyroid hormone (PTH) levels with sensitivity and accuracy of dual energy computed tomography (DECT), single-photon emission CT with Tc-sestamibi (CT-MIBI), and ultrasound (US) for pre-operative localization primary hyperparathyroid (PHP) patients.
Methods: Patients undergoing parathyroidectomy for PHP at a tertiary care facility who underwent DECT, CT-MIBI and US between 2012 and 2021 were stratified by preoperative calcium and PTH levels.
Results: Of 278 patients, those with high calcium and PTH levels had a higher sensitivity and accuracy with DECT (87.7%, 85.2%) compared to CT-MIBI (82.3%, 79.0%), and US (61.7%, 53.1%). DECT was more sensitive and accurate than other preoperative localization techniques in subgroups with normal PTH (DECT sensitivity 60.9%, accuracy 52.1%) and normal calcium levels (41.7%, 33.3%).
Conclusion: Preoperative calcium and PTH were associated with sensitivity and accuracy of pre-operative localization in PHP. DECT was sensitive and accurate for preoperative localization compared to other first-line imaging techniques.

Curative Parathyroidectomy in Primary Hyperparathyroidism Improves Both Systolic and Diastolic Cardiac Dysfunction: A Six-Month Follow-Up Study at a Tertiary Care Hospital.

Department of Endocrinology, Sher-i-Kashmir Institute of Medical Sciences (SKIMS), Srinagar, J&K, India.
Background: Primary hyperparathyroidism (PHPT) is associated with hypertension, left ventricular hypertrophy, and myocardial and valvular calcifications, leading to increased mortality rates. While the association between PHPT and diastolic dysfunction has been well-documented, data on systolic dysfunction and its reversal after curative parathyroidectomy (PTX) remains limited.
Purpose: To evaluate the effect of PTX on cardiovascular parameters, especially systolic dysfunction, in PHPT patients using conventional and speckle-tracking echocardiography (STE).
Cardiopulmonary arrest in liver transplantation surgery: Perioperative beta-blockade implication in the cirrhotic patient.

Liver transplantation (LT) has an incidence of intraoperative cardiopulmonary arrest (CPA) of around 5%. Patients who experience CPA during this procedure have a reduced survival rate of approximately 50%. Most CPAs occur during the neohepatic phase due to reperfusion syndrome, but this is not always the underlying cause, and a broad differential diagnosis must be performed.

Introduction: Patients with primary hyperparathyroidism (PHPT) are prone to low bone mineral density (BMD). This study aimed to explore factors associated with improved bone health after parathyroidectomy (PTx).
Methods: We conducted a retrospective analysis of patients who underwent PTx for PHPT at our institution between 2016 and 2020.

: In the presence of porcelain aorta (PA), transcatheter aortic valve replacement (TAVR) has become a class I therapeutic indication for the treatment of severe aortic valve stenosis. To date, few studies have analyzed the clinical outcomes of TAVR in PA patients. We aim to analyze the calcification patterns of the thoracic aorta in PA patients and to evaluate their clinical implications for TAVR procedures.

: Parathyroidectomy (PTX) is generally curative in renal hyperparathyroidism (RHPT) that is refractory to medical treatment in end-stage kidney disease (ESKD) patients. Severe hypocalcemia is a common complication of PTX and results in increased monitoring, interventions, lengths of stay, and costs of care. This study aimed to find the determinants and cutoff values of the biochemical determinants, if any, for severe post-operative hypocalcemia after PTX in adult patients with ESKD.
