Ann Nucl Med 2020 May 20. Epub 2020 May 20.

Department of Nuclear Medicine, Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Hualien, Taiwan.

Objectives: Currently, neck ultrasound is the preferred preoperative imaging in patients with secondary/tertiary hyperparathyroidism, and the use of Tc-99m sestamibi scan is limited in these patients. We conducted this study to compare the diagnostic utilities of F-18 fluorocholine PET/CT, Tc-99m sestamibi scintigraphy, and neck ultrasound for localizing hyperfunctioning parathyroid glands in secondary/tertiary hyperparathyroidism.

Methods: We prospectively enrolled 30 dialysis patients with a diagnosis of secondary/tertiary hyperparathyroidism; of these, 27 participants underwent all three imaging modalities, including dual-phase F-18 fluorocholine PET/CT (PET acquired 5 and 60 min after tracer injection), dual-phase Tc-99 m sestamibi SPECT/CT, and neck ultrasound.

Surgical Treatment of Primary Hyperparathyroidism: Which Therapy to Whom?

Sisli Etfal Hastan Tip Bul 2019 27;53(3):201-214. Epub 2019 Aug 27.

Department of General Surgery, Health Sciences University, Sisli Hamidiye Etfal Training and Research Hospital, Istanbul, Turkey.

Primary hyperparathyroidism (pHPT) is characterized by an increase in the levels of PTH and Ca, or one of these (Ca, PTH) as a result of a dysregulation of calcium (Ca) metabolism due to inappropriate excess parathyroid hormone (PTH) autonomously produced from one or more than one parathyroid glands. Ninety to 95% of pHPT is a sporadic type, which is not associated with the familial history and other endocrine organ tumors, and 5-10% of it is hereditary. While 80-85% of pHPT arises from a single parathyroid adenoma, 4-5% is caused by a double adenoma, 10-15% by multigland hyperplasia and less than 1% by parathyroid cancer. Read More

Chirurgia (Bucur) 2019 Sept-Oct;114(5):541-549

It is estimated that up to 90% of patients with chronic kidney disease develop secondary hyperparathyroidism (sHPT). Although the disease has multiple manifestations, the most important pathological feature, from the point of view of increased mortality, is represented by the ectopic arterial, myocardial and cardiac valvular calcifications. The calcifications are progressive and lead to high blood pressure, left ventricular hypertrophy, atrio-ventricular blocks, angina and myocardial infarction. Read More

Pre-operative Localisation of the Parathyroid Glands in Secondary Hyperparathyroidism: A Retrospective Cohort Study.

Sci Rep 2019 10 10;9(1):14634. Epub 2019 Oct 10.

Nagoya Daini Red Cross Hospital, Department of Transplant and Endocrine Surgery, 466-8650, 2-9 Myoken-cho, Showa-ku, Nagoya, Aichi, Japan.

Complete parathyroidectomy (PTx) is essential during total PTx for secondary hyperparathyroidism (SHPT) to prevent recurrent and persistent hyperparathyroidism. Pre-operative imaging evaluations, including computed tomography (CT), ultrasonography (US), and Tc-99m sestamibi (MIBI) scans, are commonly performed. Between June 2009 and January 2016, 291 patients underwent PTx for SHPT after pre-operative evaluations involving CT, US, and MIBI scans, and the diagnostic accuracies of these imaging modalities for identifying the parathyroid glands were evaluated in 177 patients whose intact parathyroid hormone (PTH) levels were <9 pg/mL after the initial PTx.

Uremic leontiasis ossea due to secondary hyperparathyroidism complicated by vitamin C deficiency in a non-adherent chronic hemodialysis patient: A case report.

Clin Nephrol Case Stud 2019 9;7:54-59. Epub 2019 Sep 9.

Department of Medicine.

Non-adherence to medical therapy in patients with end-stage kidney disease (ESKD) can lead to severe metabolic derangements rarely seen in the current medical era. Such complications may take the form of secondary hyperparathyroidism (HPT) leading to rare manifestations of bone mineral disease, and profound vitamin C deficiency from poor nutrition combined with removal of water-soluble vitamins during dialysis. Secondary HPT causes renal osteodystrophy which can lead to diffuse enlargement of the facial skeleton and morphological changes suggestive of leontiasis ossea. Read More

Coexistent papillary thyroid carcinoma diagnosed in surgically treated patients for primary versus secondary hyperparathyroidism: same incidence, different characteristics.

BMC Surg 2019 Jul 16;19(1):94. Epub 2019 Jul 16.

Faculty of Medicine, Department of Surgery, "Grigore T Popa" University of Medicine and Pharmacy, 16 Universitatii Str, 700115, Iasi, Romania.

Background: The coexistence of hyperparathyroidism and thyroid cancer presents important diagnostic and management challenges. With minimally invasive parathyroid surgery trending, preoperative thyroid imaging becomes more important as concomitant thyroid and parathyroid lesions are reported. The aim of the study was to evaluate the rate of thyroid cancer in patients operated for either primary (PHPT) or secondary hyperparathyroidism (SHPT). Read More

Are Tc-99m-Sestamibi Scans in Patients With Secondary Hyperparathyroidism and Renal Failure Needed?

J Surg Res 2019 11 2;243:380-383. Epub 2019 Jul 2.

Department of Surgery, University of Alabama at Birmingham, Birmingham, Alabama. Electronic address:

Background: Parathyroidectomy for patients with secondary hyperparathyroidism (sHPT) generally requires a four-gland exploration. Some groups have strongly recommended routine preoperative Tc-99m-sestamibi scans; others practice scanning for only selected patients. To determine the utility of sestamibi scans in this patient population, we reviewed our experience. Read More

Unusual recurrent renal secondary hyperparathyroidism caused by hyperplastic autograft with supernumerary parathyroid adenoma: A case report.

Medicine (Baltimore) 2019 Jun;98(24):e16077

Rationale: Secondary hyperparathyroidism (SHPT) is often complicated with chronic renal failure. Though the total parathyroidectomy (TPTX) with forearm autotransplantation (FAT) has been commonly used to treatment refractory renal SHPT, the recurrence of SHPT is not infrequent, resulting from hyperplastic autograft, remnant parathyroid tissues, and supernumerary parathyroid gland (SPG).

Patient Concerns: A 67-year-old man undergoing TPTX+FAT 4 years previously for renal SHPT, who received regular hemodialysis with active vitamin D supplements of Rocaltrol treatment postoperatively, was admitted to our hospital with progressively elevated serum intact parathyroid hormone (iPTH) from 176 to 1266 pg/mL for 8 months and bilateral ankle joints pain for 1 month.

Hypertension is a common problem; if left untreated, it can result in significant complications, including those involving the cardiovascular system and end organs. Approximately 10% of patients with hypertension are classified as having , defined as hypertension attributable to a specific and potentially remediable cause. The evaluation for secondary hypertension typically begins with acquiring the patient history and performing a physical examination and screening laboratory tests. Read More

Usefulness of 18F-Fluorocholine Positron Emission Tomography-Computed Tomography in Locating Lesions in Hyperparathyroidism: A Systematic Review.

JAMA Otolaryngol Head Neck Surg 2019 May 30. Epub 2019 May 30.

Department of Head and Neck Surgery, Hospital Italiano de Buenos Aires, Buenos Aires, Argentina.

Importance: Identifying parathyroid glands correctly before a surgical procedure is essential to perform minimally invasive surgery. First-line tests with discordant or negative results underscore the need for more accurate imaging tests, thus decreasing the requirement for bilateral neck exploration or reintervention.

Objective: To review the available evidence to determine positive predictive value, negative predictive value, sensitivity, and specificity in clinical cases in which 18F-fluorocholine positron emission tomography-computed tomography (PET/CT) could be useful as a method to locate the lesions, and the benefits and controversial aspects of the method.

DIAGNOSIS OF ENDOCRINE DISEASE: Evaluation of bone fragility in endocrine disorders.

Eur J Endocrinol 2019 Apr 1. Epub 2019 Apr 1.

I Chiodini, Department of Clinical Sciences and Community Health, University of Milan, Milan, Italy.

An underlying disease affecting bone health is present in up to 40% and 60% of osteoporotic post-menopausal women and men respectively. Among the disorders leading to a secondary form of osteoporosis, the endocrine diseases are highly represented. A frequent finding in patients affected with an endocrine-related forms of bone disease is that the skeletal fragility is partially independent of the bone density, since the fracture risk in these patients is related more to a reduction of bone quality than to a decrease of bone mass.

Appearances of soft tissue calcification on Tc99m MDP bone scan.

J Pak Med Assoc 2019 Apr;69(4):600

Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan.

Metastatic calcification relates to abnormal calcification resulting from hypercalcaemia in otherwise normal tissues. Hypercalcaemia can occur secondary to chronic renal failure, hyperparathyroidism, hypervitaminosis D, and metastatic neoplasms. Specific symptoms are often lacking, but calcification may be a marker of disease severity and its chronicity. Read More

Novel insights into parathyroid hormone: report of The Parathyroid Day in Chronic Kidney Disease.

Clin Kidney J 2019 Apr 20;12(2):269-280. Epub 2018 Jul 20.

Division of Nephrology, Ambroise Paré University Medical Center, APHP, University of Paris Ouest (UVSQ), Boulogne Billancourt/Paris, France.

Chronic kidney disease (CKD) is often associated with a mineral and bone disorder globally described as CKD-Mineral and Bone Disease (MBD), including renal osteodystrophy, the latter ranging from high bone turnover, as in case of secondary hyperparathyroidism (SHPT), to low bone turnover. The present article summarizes the important subjects that were covered during 'The Parathyroid Day in Chronic Kidney Disease' CME course organized in Paris in September 2017. It includes the latest insights on parathyroid gland growth, parathyroid hormone (PTH) synthesis, secretion and regulation by the calcium-sensing receptor, vitamin D receptor and fibroblast growth factor 23 (FGF23)-Klotho axis, as well as on parathyroid glands imaging.
