Primary hyperparathyroidism is overproduction of parathyroid hormone, causing hypercalcemia. Parathyroid adenomas have been found to be the etiology for 80% of cases of primary hyperparathyroidism, while almost a quarter of them are ectopic. We present a case of ectopic thymic parathyroid adenoma, treated by the thoracoscopic approach. Preoperative computed tomogram and technetium-99-sestamibi imaging showed an adenoma, located in the front mid-mediastinum, approximately 8 × 10 mm in size. Resection of the tumor was indicated according to the persistent hypercalcemia after unsuccessful surgical treatment performed 3 years ago...

Parathyroid hormone-related protein (PTHrP), which is released in the presence of malignant disease, is associated with hypercalcemia. Complete resection of the tumor in such patients is rarely performed because of their poor general condition. We herein report a case of lung cancer associated with PTHrP in a patient whose condition dramatically improved after surgery. We also review the literature on the benefits of various surgical options. Although only a few cases of complete resection in such patients have been reported, the mental and physical condition of the patients improved postoperatively and the median survival time was longer than 12 months...

We present a case of osteitis fibrosa cystica (OFC), also known as "brown tumor." A 55-year old female was admitted to the hospital with several months of right hip pain that was becoming more severe. A malignant lesion of the pelvis was suspected after initial imaging studies. Significant hypercalcemia led to a diagnosis of hyperparathyroidism and ultimately a benign parathyroid adenoma. Surgical excision of the adenoma resulted in full resolution of the tumor in her pelvis as well as her pain. It is important to keep OFC, or brown tumor, in your differential diagnoses when presented with a bone lesion...

RATIONALE: Parathyroid hormone PTH) levels are the main parameters to differentiate primary hyperparathyroidism (PHPT) from non-PTH-dependent hypercalcemia. We report a case of hypercalcemia with normal PTH levels due to a parathyroid adenoma. PATIENT CONCERNS: A 52-year-old female patient presented with 2-year history of documented sustained high-normal serum calcium and hypercalcemia (2.51-3.03 mmol/L) with normal serum intact PTH levels (21.95-40.15 pg/ mL)...

An enigmatic association between sarcoidosis and lymphoma has been proposed in the past. This poses a significant diagnostic challenge, especially when the time interval is less than one year between the two diagnoses. A 54-year-old male patient presented to his primary care physician with worsening acute kidney injury and hypercalcemia. His chest x-ray showed bilateral interstitial nodular thickening and mild bilateral hilar fullness. After a diagnostic workup, the patient was diagnosed with sarcoidosis and started on prednisone...

In patients with lung malignancy, the development of malignant hypercalcemia (MH) carries a dismal prognosis and represents a major therapeutic challenge given that conventional medical treatments have limited durability. Robust and lasting hypercalcemic reversal and symptomatic relief have been documented following surgical tumor resection. Stereotactic body radiation therapy (SBRT) has emerged as an effective treatment modality in medically inoperable patients with Stage I non-small cell lung cancer (NSCLC)...

Bone constitutes the most common site of breast cancer metastases either at time of presentation or recurrent disease years after seemingly successful therapy. Bone metastases cause substantial morbidity, including life-threatening spinal cord compression and hypercalcemia. Given the high prevalence of patients with breast cancer, health-care costs of bone metastases (>$20,000 per episode) impose a tremendous economic burden on society. To investigate mechanisms of bone metastasis, we developed femoral artery injection of cancer cells as a physiologically relevant model of bone metastasis...

Clinical and experimental studies indicate a possible link between high serum levels of fibroblast growth factor 23 (FGF23), phosphate, and parathyroid hormone (PTH), deficiency of active vitamin D (1,25D) and klotho with the development of pathological cardiac remodeling, i.e., left ventricular hypertrophy and myocardial fibrosis, but a causal link has not been established so far. Here, we investigated the cardiac phenotype in klotho hypomorphic ( kl/kl ) mice and Hyp mice, two mouse models of elevated FGF23 levels and klotho deficiency, but differing in parameters of mineral metabolism, by using histology, quantitative real-time PCR, immunoblot analysis, and serum and urine biochemistry...

We investigated therapeutic potential of human tonsil-derived mesenchymal stem cells (TMSC) subcutaneously delivered to ovariectomized (OVX) mice for developing more safe and effective therapy for osteoporosis. TMSC were isolated from tonsil tissues of children undergoing tonsillectomy, and TMSC-embedded in situ crosslinkable gelatin-hydroxyphenyl propionic acid hydrogel (TMSC-GHH) or TMSC alone were delivered subcutaneously to the dorsa of OVX mice. After 3 months, three-dimensionally reconstructed micro-computed tomographic images revealed better recovery of the femoral heads in OVX mice treated with TMSC-GHH...

CME: Multiple Myeloma - a Review Abstract. Multiple myeloma accounts for 1 % of all malignancies, and its incidence increases with age. Both the symptoms and the course of the disease are heterogeneous. While some patients experience unspecific complaints, e.g. malaise or lethargy, others might present with emergency situations like hypercalcemia, spinal cord compression or hyperviscosity, so that an urgent therapy initiation is crucial. The aim of this article is to review the most common initial symptoms, typical emergencies, as well as diagnostics and therapy of multiple myeloma...

Paraneoplastic syndromes are defined as a combination of clinical disorders associated with malignant diseases that are caused by the secretion of various substances by the tumor without, however, being caused by the direct growth and infiltration of the primary tumor, or due to the development of distant metastases. Despite the fact that lung cancer represents the number one cause of death from cancer worldwide, the new methods of treatment increase patient survival and the incidence of paraneoplastic syndromes...

Although the kidney was initially thought to be the sole organ responsible for the production of 1,25(OH)2 D via the enzyme CYP27b1, it is now appreciated that the expression of CYP27b1 in tissues other than the kidney is wide spread. However, the kidney is the major source for circulating 1,25(OH)2 D. Only in certain granulomatous diseases such as sarcoidosis does the extra renal tissue produce sufficient 1,25(OH)2 D to contribute to the circulating levels, generally associated with hypercalcemia, as illustrated by the case report preceding the review...

Parathyroid cysts (PCs) are relatively rare entities, with an even smaller proportion that functionally produce parathyroid hormone (PTH). Given associated hypercalcemia, often symptomatic, as well as potentially related osteoporosis and/or nephrolithiasis, resection of these functional cysts is often indicated. This case report details the management course for a patient who presented with primary hyperparathyroidism and was ultimately found to have a functional intrathymic PC. During initial workup, 4-dimensional computed tomography (4D-CT) of the neck demonstrated enlarged left upper and right lower parathyroid glands; however, the patient's hyperparathyroid state persisted even after bilateral neck exploration and resection of these two glands...

BACKGROUND: Prenatal diagnosis of hyperechogenic kidneys is associated with a wide range of etiologies and prognoses. The recent advances in fetal ultrasound associated with the development of next-generation sequencing for molecular analysis have enlarged the spectrum of etiologies, making antenatal diagnosis a very challenging discipline. Of the various known causes of hyperechogenic fetal kidneys, calcium and phosphate metabolism disorders represent a rare cause. An accurate diagnosis is crucial for providing appropriate genetic counseling and medical follow-up after birth...

Chemoprevention is based on the use of non-toxic, pharmacologically active agents to prevent tumor progression. In this regard, natural dietary agents have been described by the most recent literature as promising tools for controlling onset and progression of malignancies. Extensive research has been so far performed to shed light on the effects of natural products on tumor growth and survival, disclosing the most relevant signal transduction pathways targeted by such compounds. Overall, anti-inflammatory, anti-oxidant and cytotoxic effects of dietary agents on tumor cells are supported either by results from epidemiological or animal studies, and even by clinical trials...

Amyloidosis is a group of diseases characterized by an irreversible and extracellular deposition of fibrillar, amorphous protein known as amyloid in different organs and tissues. Amyloid deposits may occur locally in tissues or may involve various organs, resulting in a wide range of clinical manifestations. Amyloidosis of the head and neck is rarely seen and can reflect some plasma cell dyscrasia that affects B lymphocytes. Deposition of amyloid on the tongue is very rare and accounts for less than 9% of all types of amyloidosis...

Hypercalcemia presenting in ovarian cancer is uncommon in the clinic. Here, two cases of ovarian epithelial carcinoma that presented with severe hypercalcemia were reported, with a review of the literature. The laboratory findings and stepwise clinical investigations of these two cases differed, indicating distinct underlying causes of hypercalcemia. In case one, the serum levels and immunostaining for parathyroid hormone-related protein (PTHrP) verified humoral hypercalcemia of malignancy (HHM). In case two, the high level of parathyroid hormone (PTH) and the scintigraphy scan showing parathyroid gland adenoma confirmed primary hyperparathyroidism-induced hypercalcemia...

INTRODUCTION: Sarcoidosis is a systemic inflammatory disease of unknown etiology, characterized by the presence of non-caseating granulomas in several organs; renal impairment alone is a rare condition. When it affects the kidneys, the most prevalent manifestations are hypercalcemia and hypercalciuria. This paper aims to address the topic of renal sarcoidosis, by means of a case report, and reinstate the importance of histopathology in its diagnosis. METHODS: The data came from an observational clinical study with a qualitative approach, through an interview with the renal sarcoidosis patient and data from her medical records...
