Insights

Hypercalcemia, a common metabolic disorder, affects 3-30% of cancer patients. Its prevalence varies significantly between hospital and general populations, presenting diagnostic challenges.

Area of Science:

  • Endocrinology
  • Metabolic Disorders
  • Oncology

Background:

  • Hypercalcemia is a frequent metabolic complication, particularly in patients with malignant diseases.
  • It affects a significant percentage of cancer patients, ranging from 3% to 30%.

Purpose of the Study:

  • To review and analyze the existing literature on the prevalence of hypercalcemia.
  • To compare hypercalcemia prevalence in general (normal) and hospital-based populations.

Main Methods:

  • Literature search of the MEDLINE database from 1980 to March 1995.
  • Inclusion of studies identified through bibliographies of selected articles.

Main Results:

  • Hypercalcemia of malignancy is the leading cause in hospital settings; primary hyperparathyroidism is most common in the general population.
  • Prevalence in hospital populations varies from 0.17% to 2.92%, while in normal populations it ranges from 1.07% to 3.9%.
  • Diagnostic challenges are highlighted, with reported diagnosis rates as low as 25% and overlooked cases ranging from 20-50%.

Conclusions:

  • Significant discrepancies exist in hypercalcemia prevalence data between different populations.
  • Varying diagnostic criteria, referral patterns, and hospital demographics contribute to prevalence variations.
  • Hypercalcemia diagnosis remains a significant clinical challenge, requiring improved detection and reporting.

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
Synthesis and Functions of Calcitonin00:51

Synthesis and Functions of Calcitonin

Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...
The Parathyroid Glands00:59

The Parathyroid Glands

The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
Hyperglycemia01:29

Hyperglycemia

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
