INTRODUCTION
Blood bone metabolic biomarkers are noninvasive indices for evaluating metabolic bone diseases. We investigated the relationships between blood bone metabolic biomarkers and anemia in chronic kidney disease (CKD) patients and analyzed the effects of parathyroidectomy (PTX) on the above indices.
METHODS
In this cross-sectional study, 100 healthy controls and 239 CKD patients, including 46 secondary hyperparathyroidism (SHPT) patients with PTX, were enrolled. Moreover, a prospective study was conducted in which 28 PTX patients were followed up. The degree of anemia was classified as mild, moderate, or severe based on the tertiles of hemoglobin (Hb) levels of the anemic CKD patients, with cutoff values of 83 g/L and 102 g/L. Bone metabolic biomarkers, including calcium (Ca), phosphorus (P), intact parathyroid hormone (iPTH), fibroblast growth factor 23 (FGF23), and α-klotho, were tested.
RESULTS
The mean estimated glomerular filtration rate (eGFR) in CKD patients was 25.7 ± 36.0 ml/min/1.73 m, and 84.10% of CKD patients had anemia. The baseline Hb levels in the mild, moderate, and severe anemia subgroups were 110.86 ± 5.99 g/L, 92.71 ± 5.96 g/L, and 67.38 ± 10.56 g/L, respectively. CKD patients had higher adjusted Ca, P, alkaline phosphatase (ALP), iPTH, and FGF23 levels and lower α-klotho levels than controls. Baseline adjusted Ca, P, iPTH, and α-klotho levels were associated with Hb levels in CKD patients. Blood adjusted Ca, P, and iPTH levels were correlated with anemia severity. After PTX (median interval: 6.88 months), anemia and high blood adjusted Ca, P, iPTH, and FGF23 levels were ameliorated, while α-klotho levels were increased.
CONCLUSIONS
Blood adjusted Ca, P, iPTH, and α-klotho levels were correlated with Hb levels in CKD patients. Correction of bone metabolic disorders may be a therapeutic strategy for anemia treatment.

Review
INTRODUCTION
Traditional parathyroid registries are labor-intensive and do not always capture long-term follow-up data. This study aimed to develop a patient-driven international parathyroid registry and leverage community connections to improve patient-centered care for hyperparathyroidism.
METHODS
An anonymous voluntary online survey was developed using Qualtrics and posted in an international patient and advocate-run social media group affiliated with over 11,700 members. The survey was developed from a literature review, expert opinion, and discussion with the social media group managers. It consists of seven sections: patient demographics, past medical history, preoperative symptoms, laboratory evaluation, preoperative imaging studies, operative findings, and operative outcomes.
RESULTS
From July 30, 2022, to October 1, 2022, 89 complete responses were received. Participants were from 12 countries, mostly (82.0%) from the United States across 31 states. Most participants were female (91.4%), White (96.7%) with a mean (±standard deviation) age of 58 ± 12 y. The most common preoperative symptoms were bone or joint pain (84.3%) and neuropsychiatric symptoms: including fatigue (82.0%), brain fog (79.8%), memory loss (79.8%), and difficulty with concentration (75.3%). The median (interquartile range) length from symptom onset to diagnosis was 40.0 (6.8-100.5) mo. Seventy-one percent of participants had elevated preoperative serum calcium, and 73.2% had elevated preoperative parathyroid hormone. All participants obtained preoperative imaging studies (88.4% ultrasound, 86.0% sestabimi scan, and 45.3% computed tomography). Among them, 48.8% of participants received two, and 34.9% had three imaging studies. The median (interquartile range) time from diagnosis to surgical intervention was 3 (2-9) mo. Twenty-two percent of participants traveled to different cities for surgical intervention. Forty-seven percent of participants underwent outpatient parathyroidectomy. Eighty-four percent of participants reported improved symptoms after parathyroidectomy, 12.4% required oral calcium supplementation for more than 6 mo, 32.6% experienced transient hoarseness after parathyroidectomy, and 14.6% required reoperation after initial parathyroidectomy.
CONCLUSIONS
This international online parathyroid registry provides a valuable collection of patient-entered clinical outcomes. The high number of responses over 10 wk demonstrates that participants were willing to be involved in research on their disease. The creation of this registry allows global participation and is feasible for future studies in hyperparathyroidism.

INTRODUCTION
Endoscopic parathyroidectomy(EPTX) has been gradually introduced as a minimally invasive treatment for refractory secondary hyperparathyroidism (SHPT). However, it is uncertain about the efficacy and safety compared between EPTX and open parathyroidectomy (OPTX) for refractory SHPT.
AIM
This meta-analysis was conducted to evaluate the efficacy and safety of EPTX and OPTX for secondary hyperp arathyroidism (SHPT).
MATERIAL AND METHODS
Databases including PubMed, EMbase, Cochrane Library, CNKI, and Wanfang were searched. Eligible studies comparing EPTX and OPTX for refractory SHPT were included.
RESULTS
Compared with OPTX, EPTX has the shorter hospital stay (p < 0.01) and lower incidences of hoarseness or recurrent laryngeal nerve injury (p = 0.04). There was no significant difference between EPTX and OPTX concerning operation time (p = 0.49), intraoperative blood loss (p = 0.24), postoperative parathyroid hormone levels (p = 0.22), postoperative calcium levels (p = 0.93), postoperative phosphorus levels (p = 0.37), and complications including neck ecchymosis (p = 0.87), subcutaneous haematoma (p = 0.18), and wound infection (p = 0.11).
CONCLUSIONS
EPTX and OPTX are both effective methods for refractory SHPT. EPTX had the shorter hospital stay and lower incidences of hoarseness or recurrent laryngeal nerve injury.

Review
Thyroid and parathyroid disorders are quite common in the population and range from benign to malignant conditions that may be hormonally active or inactive. Select disorders of the thyroid and parathyroid can be managed medically, although there are a variety of circumstances that may require definitive management with surgery. Surgical intervention may be required for hormonal control, compressive symptoms, or for the removal and/or control of malignancy. The endocrinologist's perspective of the preoperative and postoperative management regarding thyroid and parathyroid surgeries will be discussed.

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.

Indian Journal of Otolaryngology and... Dec 2023Descriptive analysis of patients undergoing parathyroid adenoma surgery at a tertiary care hospital.
AIM
Descriptive analysis of patients undergoing parathyroid adenoma surgery at a tertiary care hospital.
METHODOLOGY
Patients with parathyroid adenoma operated from January 2016 to December 2020. Serum calcium and PTH were used to establish the diagnosis. Ultrasonography (USG) studies localized the adenoma. NIH criteria was used for decision regarding surgery. Patients were analyzed with regards to pre operative localization, biochemical monitoring and other outcomes.
RESULTS
Of the 15 eligible patients, all were symptomatic, with myalgia (34%) being the commonest symptom. Rome criteria confirmed the adequacy of the procedure by measuring intra operative drop in PTH. Average decrease in serum PTH level was 69.9% and serum calcium was 20.6% after excision of adenoma. The average size of excised adenoma was 2.5 cm. There were no post operative complications and all patients were normocalcemic on follow up.
CONCLUSION
Parathyroidectomy is a simple, safe and effective solution that reduces the morbidity of symptomatic primary hyperparathyroidism patients. Pre operative localization studies affirm the diagnosis and intra operative biochemical confirmation clinches the adequacy of resection.

We present the case of a 68-year-old woman with a painful tibial tumor and fatigue. Histology and laboratory studies were consistent with a brown tumor secondary to initially unrecognized, severe primary hyperparathyroidism. 18 F-fluorocholine PET/CT revealed a large hypermetabolic parathyroid mass and multiple bone foci considered as brown tumors. Unilateral neck exploration confirmed a large parathyroid adenoma. Serum calcium and parathyroid hormone levels normalized quickly, and symptoms subsided gradually after parathyroidectomy. Brown tumors are a rare complication of severe hyperparathyroidism. 18 F-fluorocholine PET/CT allows the localization of parathyroid adenomas and brown tumors, and can be used as a single imaging modality.

Meta-Analysis
CONTEXT
Primary hyperparathyroidism (PHPT) is the most common cause of hypercalcemia, yet long-term (5- and 10-year) recurrence rates after curative surgery have been unclear.
OBJECTIVE
To perform the first systematic review and meta-analysis investigating the long-term recurrence rates of sporadic PHPT after successful parathyroidectomy.
METHODS
A comprehensive search of multiple databases (including PubMed, EMBASE, Cochrane, EBSCO-CINHAL, EMBASE, Ovid, Scopus, and Google Scholar) was performed from each database's inception to January 18, 2023. Observational studies reporting at least 5 years of follow-up data after surgical resection were included. Two reviewers independently screened articles for relevance. Of 5769 articles initially identified, 242 were examined in full-text review and 34 were deemed eligible for inclusion. Two authors independently performed data extraction and study appraisal, using the National Institutes of Health study quality assessment tools.
RESULTS
Of 30 658 participants, 350 patients (1.1%) experienced recurrence after resection. A meta-analysis of proportions was performed to obtain the pooled recurrence rates. The pooled estimate for overall recurrence rate was 1.56% (95% CI 0.96-2.28%; I2 = 91%). The pooled estimates for 5- and 10-year recurrence rate after resection were 0.23% (0.04-0.53%, 19 studies; I2 = 66%) and 1.03% (0.45-1.80%, 14 studies; I2 = 89%), respectively. Sensitivity analyses did not find a statistically significant difference when adjusting for study size, diagnosis, or surgical approach.
CONCLUSION
Approximately 1.56% of sporadic PHPT patients eventually develop recurrence following parathyroidectomy. The initial diagnosis and procedure type does not influence recurrence rates. Consistent long-term follow-up is warranted to help identify recurrent disease.

Review
Thyroid and parathyroid surgery requires careful dissection around the vascular pedicle of the parathyroid glands to avoid excessive manipulation of the tissues. If the blood supply to the parathyroid glands is disrupted, or the glands are inadvertently removed, temporary and/or permanent hypocalcemia can occur, requiring post-operative exogenous calcium and vitamin D analogues to maintain stable levels. This can have a significant impact on the quality of life of patients, particularly if it results in permanent hypocalcemia. For over a decade, parathyroid tissue has been noted to have unique intrinsic properties known as "fluorophores," which fluoresce when excited by an external light source. As a result, parathyroid autofluorescence has emerged as an intra-operative technique to help with identification of parathyroid glands and to supplement direct visualization during thyroidectomy and parathyroidectomy. Due to the growing body of literature surrounding Near Infrared Autofluorescence (NIRAF), we sought to review the value of using autofluorescence technology for parathyroid detection during thyroid and parathyroid surgery. A literature review of parathyroid autofluorescence was performed using PubMED. Based on the reviewed literature and expert surgeons' opinions who have used this technology, recommendations were made. We discuss the current available technologies (image vs. probe approach) as well as their limitations. We also capture the opinions and recommendations of international high-volume endocrine surgeons and whether this technology is of value as an intraoperative adjunct. The utility and value of this technology seems promising and needs to be further defined in different scenarios involving surgeon experience and different patient populations and conditions.
