Endocr Pract 2024; 30:225-230. [PMID: 38086526 DOI: 10.1016/j.eprac.2023.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 11/29/2023] [Accepted: 12/06/2023] [Indexed: 01/24/2024]
Abstract
OBJECTIVE Apart from renal stones, primary hyperparathyroidism (PHPT) has been linked to the occurrence of gallstone disease (GSD). Nevertheless, the association is not consistent across all studies. The present systematic review and meta-analysis aims to collate the hitherto available evidence and provide a pooled estimate of the association between GSD and PHPT. METHODS PubMed/MEDLINE, Embase, and Web of Science databases were systematically searched from inception till May 10, 2023 for observational studies reporting the prevalence of GSD (in terms of absolute numbers) in patients with PHPT. The pooled prevalence of GSD and odds ratio with 95% CI of the occurrence of GSD in patients with PHPT as compared to age- and sex-matched controls were calculated. Subgroup analysis was performed based on patient ethnicity (Indian/Caucasian). Statistical analysis was carried out using R version 4.2.2. Random-effects model with Hartung-Knapp adjustment was used for analyses. RESULTS A total of 7 observational studies were included, pooling data from 15 949 patients with PHPT. The pooled prevalence of GSD in patients with PHPT was 16% (95% CI: 7%, 25%, I2 = 99%), being 13% (95% CI: 0%, 66%, I2 = 76%) in Indians, and 17% (95% CI: 4%, 31%, I2 = 99%) in Caucasians. Data consolidated from 3 studies showed that the pooled odds ratio of occurrence of GSD in patients with PHPT compared to controls was 1.77 (95% CI: 1.60, 1.97, P < .001, I2 = 0%). CONCLUSIONS GSD is more prevalent in patients with PHPT than in the general population. Thus, PHPT may be considered an additional risk factor for GSD.

Abstract
OBJECTIVE Parathyroid adenoma is less common than in adulthood, but its morbidity is higher in children. We aimed to evaluate the clinical characteristics of parathyroid adenoma and our clinical experience since the early disease is often asymptomatic and late diagnosed. MATERIALS AND METHODS From 2010 to 2020, all children diagnosed with parathyroid adenoma at our institution were reviewed. We evaluated clinical, biochemical, and radiological aspects and follow-up characteristics. RESULTS Eight subjects (F/M = 6/2) ranged in age from 10 to 17 years. Three were symptomatic. The symptoms and findings were stomachache (n = 3), myalgia (n = 2), weakness (n = 2), pancreatitis (n = 1), constipation (n = 1), nausea (n = 1), bone ache (n = 1), and anorexia (n = 1). Laboratory findings on admission were as follows: the mean calcium was 12.59 ± 1.28 (11.2-15.3) mg/dL and the mean parathyroid hormone was 244.81 ± 173.61 (74.9-645.4) pg/mL. The most common localization was the lower part of the left parathyroid gland. Parathyroid adenoma could not be demonstrated by ultrasonography in 2 patients. Tc-99m-Sestamibi scintigraphy revealed the presence of parathyroid adenoma in only 7 of 8 patients. All underwent parathyroidectomy. In our follow-up, 2 subjects needed reoperation. A molecular analysis of 6 cases could be done. One was MEN1 positive. RET sequence analysis of 2, and Casr, GNA11, and AP2S1 sequence analysis of 3 were normal. CONCLUSION Parathyroid adenoma should be considered in children older than the first decade with hypercalcemia. Suspected cases should undergo both ultrasonography and scintigraphy. Early diagnosis prevents the patients from serious complications of hypercalcemia such as nephrocalcinosis, diabetes insipid, and arrhythmia. It is significant to perform surgery in centers experienced in parathyroidectomy to minimize postoperative complications.

Abstract
Disorders of calcium homeostasis are the most frequent metabolic bone and mineral disease encountered by endocrinologists. These disorders usually manifest as primary hyperparathyroidism (PHPT) or hypoparathyroidism (HP), which have a monogenic aetiology in 5%-10% of cases, and may occur as an isolated endocrinopathy, or as part of a complex syndrome. The recognition and diagnosis of these disorders is important to facilitate the most appropriate management of the patient, with regard to both the calcium-related phenotype and any associated clinical features, and also to allow the identification of other family members who may be at risk of disease. Genetic testing forms an important tool in the investigation of PHPT and HP patients and is usually reserved for those deemed to be an increased risk of a monogenic disorder. However, identifying those suitable for testing requires a thorough clinical evaluation of the patient, as well as an understanding of the diversity of relevant phenotypes and their genetic basis. This review aims to provide an overview of the genetic basis of monogenic metabolic bone and mineral disorders, primarily focusing on those associated with abnormal calcium homeostasis, and aims to provide a practical guide to the implementation of genetic testing in the clinic.

Abstract
PURPOSE To confirm the exact break-point of a novel long-range deletion discovered in one female parathyroid carcinoma (PC) patient who has a strong family history suggesting familial hyperparathyroidism, and to investigate the expression of parafibromin in the patient's affected lesion. METHODS Clinical information of one female patient as well as five of her relatives was collected. Their genomic DNA extracted from peripheral blood went through Sanger sequencing and multiplex ligation-dependent probe amplification (MLPA). After completing whole genome sequencing (WGS), clone sequencing was also performed, whose result was aligned with standard human genome database after Sanger sequencing. RESULTS The medical history of recurrent hypercalcemia after parathyroidectomy and histopathological investigation confirmed that the female patient was diagnosed with PC. WGS displayed a novel 130 kb long-range deletion spanning UCHL5 to CDC73 that was later confirmed by clone sequencing. MLPA showed similar results in four of her five relatives, suggesting these people to be carriers of the same long-range deletion, and three among them had a history of primary hyperparathyroidism (PHPT) ahead of the proband's first visit. CONCLUSIONS We discovered a novel 130 kb long-range deletion spanning CDC73 in a family of 5 persons, and the existence of the deletion was related to PHPT and PC. Our discovery validated the role of CDC73 mutation in the occurrence of PHPT and PC, which provided new information to the genetic studies of PC.

Abstract
Parathyroid carcinoma (PC) is an extremely rare disease. Although it may occasionally occur in genetic syndromes, it is more often sporadic. It is usually associated with a consistent secretion of PTH, causing severe hypercalcemia and potentially all clinical conditions due to primary hyperparathyroidism. Management of PC can be challenging: some clinical, biochemical, and radiological features may be useful, but the final diagnosis of malignancy strictly relies on histological criteria. To date, radical surgery is the first-choice treatment and is the only effective therapy to control hypercalcemia and other clinical manifestations. On the other hand, chemo- or radiotherapy, local treatments, or novel drugs should be reserved for selected cases. We report an exceptionally unusual case of life-threatening PC, associated with several systemic manifestations: moderate pancreatitis, portal thrombosis, kidney stones, brown tumors, osteoporosis, hungry bone syndrome (HBS), chondrocalcinosis, neuropathy, and depression. The clinical case also represents an opportunity to provide a review of the recent literature, associated with a complete evaluation of the main diagnostic and therapeutic approaches.

Abstract
Primary hyperparathyroidism (PHPT) is a commonly encountered clinical problem and occurs as part of an inherited disorder in ∼10% of patients. Several features may alert the clinician to the possibility of a hereditary PHPT disorder (eg, young age of disease onset) whilst establishing any relevant family history is essential to the clinical evaluation and will help inform the diagnosis. Genetic testing should be offered to patients at risk of a hereditary PHPT disorder, as this may improve management and allow the identification and investigation of other family members who may also be at risk of disease.

Abstract
OBJECTIVE To determine whether tumor volume and tumor size are related to disease severity in parathyroid cancer (PC). METHODS Patients treated for PC at our institution were retrospectively identified. Data were collected about clinical and pathologic characteristics, laboratory parameters, tumor volume, recurrence, metastasis, and mortality. Correlation analysis was applied to laboratory parameters, tumor volume, and tumor size in PC patients. RESULTS The study included 20 patients diagnosed with PC at our center. The median follow-up was 33 months. Serum calcium (median, 12.5 mg/dL), serum parathormone (PTH) (median, 743 pg/mL), and serum alkaline phosphatase (ALP) (median, 298 U/L) levels were found to be increased, and 25-hydroxyvitamin D (25[0H)D) (median, 12.3 ng/mL) and serum phosphorus (median, 2.1 mg/dL) levels were decreased. Magnesium level was within normal limits (median, 1.9 mg/dL). The median tumor volume was 5.7 mL and median tumor size was 2.5 cm. Significant positive correlations were found between tumor volume and calcium, ALP, and PTH levels. A significant negative correlation was found between tumor volume and 25(OH)D level. There were no significant correlations between tumor size and calcium, ALP, PTH, and 25(OH)D. CONCLUSION These results found that the tumor volume affected PTH, calcium, ALP, and 25(OH)D levels. The morbidity and mortality associated with PC were usually associated with PTH secretion and hypercalcemia. Therefore, tumor volume may be a more effective parameter than tumor size when evaluating the severity of disease.

Abstract
INTRODUCTION Primary hyperparathyroidism (PHPT) is a rare condition in the pediatric population. Parathyroid carcinoma (PC) is a very uncommon cause of PHPT, accounting for < 1% of pediatric PHPT cases. It is challenging to distinguish between parathyroid adenoma (PA), the most common cause of PHPT, and PC. In this report, we described a young female who presented with a history of progressive limping and was finally diagnosed with PC. CASE PRESENTATION A 15-year-old girl presented with progressive limping and bone pain for 8 years. She was referred by an orthopedic surgeon because of elevated intact parathyroid hormone (iPTH) for further evaluation. Physical examination revealed a large, firm, and non-tender neck mass, left hip tenderness, and limited range of motion. The initial biochemistry tests showed a borderline high calcium level of 10.8 mg/dl, an elevated iPTH level of 2876 pg/mL, and a decreased phosphorus level of 2.4 mg/dL. The 99mTechnetium (Tc) sestamibi scan displayed early intense activity in the right thyroid lobe persisting in the three-hour repeat scan, compatible with a parathyroid lesion. The patient underwent right-sided neck exploration and parathyroidectomy. Intraoperative and pathology findings confirmed the diagnosis of PC. Immunohistochemistry (IHC) staining revealed creatine kinase (CK) and CD31 in endothelial cells of the tumor. Ki67 staining was also positive in 2% - 3% of tumor cells. The whole exome sequencing (WES) study was negative for cell division cycle 73 (CDC73) and multiple endocrine neoplasia 1 (MEN1) genes. CONCLUSIONS PC should be considered as a differential diagnosis of PHPT in the pediatric population, even in the presence of mild hypercalcemia.

Abstract
Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological entity characterized by subcortical vasogenic edema presenting with acute neurological symptoms. Common precipitating causes include renal failure, pre-eclampsia/eclampsia, post-organ transplant, and cytotoxic drugs. Hypercalcemia is a rare cause of PRES; most cases occur in the setting of severe hypercalcemia secondary to malignancy or iatrogenic vitamin D/calcium overdose. Primary hyperparathyroidism (PHPT), as a cause of PRES, is an oddity. We report two cases of adolescent PHPT presenting with generalized tonic-clonic seizures and altered sensorium. On evaluation, both had hypertension, severe hypercalcemia (serum calcium 14.1 mg/dL and 14.5 mg/dL, respectively) and elevated parathyroid hormone levels. Magnetic resonance imaging (MRI) revealed T2/fluid-attenuated inversion recovery hyperintensities located predominantly in the parieto-occipital regions, suggestive of PRES. Identification and excision of parathyroid adenoma led to the restoration of normocalcemia. Neurological symptoms and MRI changes improved subsequently. An extensive literature search revealed only four cases of PHPTassociated PRES; none of them being in the pediatric/adolescent age group. The predominant clinical manifestations were seizures and altered sensorium. All had severe hypercalcemia; three had hypertension at presentation, while one was normotensive. Parathyroid adenomectomy led to normalization of serum calcium and resolution of neurological symptoms and radiological changes. Thus, severe hypercalcemia, although rare in PHPT, can lead to hypercalcemic crisis precipitating acute hypertension that can result in cerebral endothelial dysfunction with the breakdown of the blood-brain barrier, culminating in PRES. We therefore recommend that serum calcium levels should be checked in all patients with PRES and that PHPT be regarded as a differential diagnosis in those with underlying hypercalcemia.

Abstract
Parathyroid glands are critical for calcium and phosphate homeostasis. Parathyroid disease is relatively rare in the pediatric population, but there are some important pediatric-specific considerations and conditions. This article reviews parathyroid physiology, disorders of hyper- and hypo- function, operative management, and uniquely pediatric diagnoses such as neonatal severe hyperparathyroidism. Advances in preoperative imaging, intra-operative gland identification, and management of post-thyroidectomy hypocalcemia are also presented in detail. This article combines a review of fundamentals with recent advances in care, emphasizing pediatric-specific publications.
