Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

6.0K
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.

Roles of Electrolytes: Calcium and Phosphate

1.3K
Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.
The calcium concentration in blood plasma is primarily...

Feedback Regulation of Calcium Concentration01:27

Feedback Regulation of Calcium Concentration

4.0K
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

Antiepileptic Drugs: Calcium Channel Blockers01:17

Antiepileptic Drugs: Calcium Channel Blockers

1.3K
Calcium channel blockers, a class of antiepileptic drugs, regulate the flow of calcium ions within neurons.
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...

Antianginal Drugs: Calcium Channel Blockers and Ranolazine

1.5K
Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...

Antihypertensive Drugs: Action of Calcium Channel Blockers01:18

Antihypertensive Drugs: Action of Calcium Channel Blockers

1.8K
Calcium ions are essential to contract smooth muscle cells in blood vessels. They enter these cells through voltage-dependent calcium channels, specifically L-type calcium channels in the cell membrane. These L-type calcium channels are integral to the excitation-contraction coupling process in smooth muscle. When a stimulus is received by smooth muscle cells, their membrane depolarizes. This alteration in membrane potential instigates the opening of L-type calcium channels. As a result,...

Summary
This summary is machine-generated.

Post-thyroidectomy calcium levels can predict normocalcemia and hypocalcemia. A standardized protocol using the calcium slope effectively manages patients and reduces hospital stays for those remaining normocalcemic.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Neurosurgery

Background:

  • Total thyroidectomy requires careful monitoring of calcium levels due to the risk of hypocalcemia.
  • Predicting postoperative calcium status is crucial for timely intervention and patient management.

Purpose of the Study:

  • To predict postoperative normocalcemia and hypocalcemia after total thyroidectomy using calcium levels.
  • To evaluate the effectiveness of a standardized protocol in managing patients undergoing total thyroidectomy.

Main Methods:

  • A prospective study of 68 patients undergoing total thyroidectomy with a standardized protocol.
  • Postoperative serum corrected calcium levels were measured at 6, 12, and 20 hours, and then twice daily.
  • Calcium slope was calculated using 6- and 12-hour serum corrected calcium levels.

Main Results:

  • Logistic regression analysis correlated the 6- and 12-hour calcium slope with postoperative normocalcemia.
  • A calcium slope of +0.02 indicated a 97% probability of remaining normocalcemic (p = 0.0007).

Conclusions:

  • The calcium slope derived from 6- and 12-hour measurements accurately predicts calcium status post-total thyroidectomy.
  • This method can also predict the risk of severe hypocalcemia.
  • Protocol implementation significantly reduced hospital stay duration for normocalcemic patients.
