Although bone disease and stone disease are the universally accepted classical manifestations of primary hyperparathyroidism, clinical parathyroid bone disease is rarely seen today in the United States (<5% of patients) and Western Europe. Nevertheless, in a given patient, classical skeletal involvement can be the first sign of primary hyperparathyroidism, but not recognized because it is not usually included, anymore, in the differential diagnosis of this manifestation of skeletal disease. We describe four cases of primary hyperparathyroidism in which the first clinical manifestation of the disease was a pathological fracture that masqueraded as a malignancy...

Bisphosphonates are drugs used to treat osteoclast-mediated bone resorption, including osteoporosis, Paget disease, multiple myeloma, cancer-related osteolysis, and malignant hypercalcemia. The use of these drugs has increased in recent years as have their complications, especially bisphosphonate-related osteonecrosis of the jaw (BRONJ), which more frequently affects the mandible. Here we report a case of BRONJ with a particularly unfavorable course due to cervical inflammation that developed into necrotizing fasciitis, followed by multiorgan involvement leading to septic shock and death...

A serum calcium level >3.5 mmol/l together with clinical symptoms such as muscle weakness, fatigue, nausea, vomiting, pancreatitis or even coma are characteristic for a hypercalcemic crisis (HC). Primary hyperparathyroidism (1HPT) and malignancy-associated hypercalcemia are the most frequent causal diseases for a HC. The analysis of serum levels for calcium, phosphorous, intact parathyroid hormone, electrophoresis and renal function parameters indicate which further radiological, scintigraphic or serum diagnostic steps are adequate to identify the cause of the patient's acute situation (i...

Hypercalcemia has many causes including primary hyperparathyroidism, malignancy, and other rare etiologies. In most of the cases, hypercalcemia is secondary to one etiology. In this case, we are reporting hypercalcemia with two causes. The initial workup showed primary hyperparathyroidism due to parathyroid adenoma. But because all features were not fully explained by primary hyperparathyroidism, further work-up revealed multiple myeloma. This case represents coexistence of two different diseases, which was rarely reported in the literature previously...

A normal serum calcium level is 8 to 10 mg/dL. The diagnosis of hypercalcemia (ie, levels 10.5 mg/dL or greater) should be confirmed with an albumin-adjusted or ionized calcium level. The two most common causes of hypercalcemia are hyperparathyroidism and malignancy. Drugs, notably lithium and thiazide diuretics, also can cause hypercalcemia. Patients with severe or symptomatic hypercalcemia should be treated initially with hydration to decrease calcium levels. The evaluation should include a parathyroid hormone (PTH) level...

Acute lymphoblastic leukemia is characterized by unchecked proliferation of malignant lymphoblasts which replaces the normal bone marrow culminating in anemia due to red blood cells inadequacy as well as in easy bruising/bleeding secondary to insufficient platelets production. Even the white blood cells which are produced excessively are immature and abnormal. ALL is the most common hematological malignancy in children. Most commonly, patients present with lymphadenopathy, recurrent infections, bleeding, fatigue, and bone pains...

BACKGROUND: Multiple myeloma (MM) is a malignant disease with a 10% frequency among all haematology neoplasms. It is characterized by clone proliferation of plasmatic cells in bone marrow, monoclonal gammopathy, and anemia, hypercalcemia, and kidney failure and bone lesions. IL-6 is an inflammatory cytokine, potential growth factor for myeloma cells, as elevated serum levels are connected with poor disease prognosis. IL-6 modulates many gene transcriptions, encoding synthesis of acute phase proteins, including C-reactive protein (CRP) and hepcidin...

Multiple endocrine neoplasia type 1 is a rare autosomal inherited disorder associated with a high risk for patients to simultaneously develop tumours of the parathyroid glands, duodeno-pancreatic neuroendocrine tumors and tumors of the anterior pituitary gland. Early identification of MEN1 in patients enables presymptomatic screening of manifestations which makes timely interventions possible with the intention to prevent morbidity and mortality. Causes of death nowadays have shifted towards local or metastatic progression of malignant neuro endocrine tumors...

Multiple myeloma is a plasma cell malignancy characterized by clonal proliferation of plasma cells in the bone marrow and associated organ damage. Usually, patients with myeloma present with a single monoclonal protein in serum and/or urine constituted by one heavy chain and one light chain. In less than 5% of the patients, more than one monoclonal protein can be identified. The aim of our retrospective multicenter matched case-control study was to describe the characteristics of cases with biclonal myeloma and compare them against a control group of monoclonal myeloma patients matched by age, sex, and year of diagnosis...

Calcitriol-mediated hypercalcemia has been reported in malignant lymphomas and granulomatous diseases but not in lung carcinoma. We describe a patient with squamous cell lung carcinoma with hypercalcemia and elevated calcitriol levels. A 60-year-old Caucasian male patient with stage IIIB squamous cell lung cancer developed hypercalcemia at 14.8 mg/dL two years after receiving chemotherapy and radiotherapy where labs showed a serum intact PTH: 7 pg/mL, PTHrP: 30 pmol/L, 1,25-hydroxyvitamin D (calcitriol): 76 pg/mL, and 25-hydroxyvitamin D levels: <4 ng/mL...

Primary hyperparathyroidism revealed by thoracic spine brown tumor and peptic ulcer bleeding is rare. We presented a case of 33-year-old male patient who was admitted with paraplegia. Thoracic spine magnetic resonance imaging (MRI) showed extradural lesion at T4 level. He underwent surgical decompression in T4. According to histopathologic finding and elevated serum parathormone (PTH) and hypercalcemia (total serum calcium 12.1 mg/dL), the diagnosis of brown tumor was down. Ultrasonography of his neck showed a well-defined lesion of 26 × 14 × 6 mm...

Parathyroid carcinoma is a very rare malignancy responsible for 0.4 to 5.2% of hyperparathyroidism. Clinical diagnosis is difficult and treatment should be codified. Surgery is the only curative treatment. We report the case of a female patient treated for malignancy-associated hypercalcemia revealing parathyroid carcinoma. The patient underwent surgery; after three months she developed lymphatic recurrence. Given the absence of other secondary involvement, bilateral lymph node dissection followed by chemotherapy was performed...

BACKGROUND: The reported proportion of cancer patients who experience hypercalcemia of malignancy (HCM) is low, particularly in the pediatric population, ranging between <1% and 5%. HCM can be observed with any type of tumor in children and occurs most commonly with leukemia. While HCM is a potentially fatal condition, the prevalence of HCM is not well understood in pediatric cancer patients. METHODS: Using the UK Clinical Practice Research Datalink, we identified pediatric cancer patients with recorded corrected serum calcium (CSC) from 2003 through 2014...

AIM: Investigate the association of calcium levels on admission and change in levels during hospitalization with hospitalization outcomes. METHODS: Historical prospective data of patients hospitalized to units of internal medicine between 2011 and 2013. Albumin-corrected-calcium levels were classified to marked hypocalcemia (<7.5 mg/dL), mild hypocalcemia (7.5-8.5 mg/dL), normal calcium (8.5-10.5 mg/dL), mild hypercalcemia (10.5-11.5 mg/dL), marked hypercalcemia (>11...

BACKGROUND: Parathyroid hormone-related protein (PTHrP) that causes hypercalcemia of malignancy appears to function as an endogenous smooth muscle relaxant. For example, PTHrP released upon bladder wall distension relaxes detrusor smooth muscle to accommodate urine. Here, we explored mechanisms underlying PTHrP-induced suppression of the smooth muscle contractility in the gastric antrum that also undergoes a passive distension. METHODS: Effects of PTHrP on phasic contractions and electrical slow waves in the antral smooth muscle of the guinea pig stomach were studied using isometric tension and intracellular microelectrode recordings, respectively...

Hypercalcemia is a rare metabolic disorder associated with hyperparathyroidism, malignancy and various other causes. Although common in adult malignancies, hypercalcemia is rare in pediatrics and purports poor prognosis. Nasopharyngeal carcinoma is rare with no reported hypercalcemic presentation. We present here a case of hypercalcemia in a child of nasopharyngeal carcinoma. A 10 year girl presented with backache for 1 month, epistaxis, cough, chest-pain for 1 week alongwith anorexia and weight loss. Investigations revealed anemia and hypercalcemia (23mg/dl; normal range 9-11 mg/dl) with hyperphosphatemia, normal parathyroid levels...

Humoral hypercalcemia of malignancy (HHM) is caused by the oversecretion of parathyroid hormone-related peptide (PTHrP) from malignant tumors. Although any tumor may cause HHM, that induced by intrahepatic cholangiocarcinoma (ICC) or gastric cancer (GC) is rare. We report here a 74-year-old male who displayed HHM with both ICC and GC and showed an elevated serum PTHrP level. Treatment of the hypercalcemia with saline, furosemide, elcatonin, and zoledronic acid corrected his serum calcium level and improved symptoms...

Primary hyperparathyroidism (PHPT) is present in up to 0.1% of the general population. The incidence is higher in women and increases with age. The majority of the cases is asymptomatic and up to 85% are due to single gland adenoma. Parathyroidectomy is the treatment of choice after localization of the hyperactive gland. Papillary Thyroid Carcinoma (PTC) is the most common cancer of the thyroid and constitutes more than 70% of thyroid malignancies. PTC can present as a single nodule or can be Multifocal. The incidence is higher in women...

Bisphosphonates are a group of drugs used for treatment in several bone diseases such as osteoporosis in women, Paget's disease, hypercalcemia of malignancy, primary malignancies of the bone and metastatic bone disease (breast and prostate carcinoma). Numerous reports in the medical literature described ocular side effects in patients treated with these drugs. We report on two patients, treated with bisphosphonates due to malignancy, who presented with unilateral and bilateral uveitis. Treatment of the ocular inflammation should include local and systemic treatment and stopping the systemic use of bisphosphonates...
