The Parathyroid Glands00:59

The Parathyroid Glands

5.4K
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...

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

4.0K
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

6.2K
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.

Bone Remodeling01:40

Bone Remodeling

40.6K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Synthesis and Functions of Calcitonin00:51

Synthesis and Functions of Calcitonin

4.8K
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...

Major Hormones and Their Functions01:27

Major Hormones and Their Functions

2.1K
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Resumen
Este resumen es generado por máquina.

El hiperparatiroidismo primario, un trastorno endocrino común, involucra altos niveles de calcio y la hormona paratiroidea. La cirugía puede curarla, pero se recomienda el monitoreo para aquellos que no se someten a cirugía.

Área de la Ciencia:

  • Endocrinología
  • Metabolismo del calcio
  • Trastornos minerales

Sus antecedentes:

  • El hiperparatiroidismo primario es un trastorno endocrino frecuente que afecta el metabolismo del calcio.
  • Se caracteriza por hipercalcemia y niveles elevados de la hormona paratiroidea.
  • La condición generalmente es el resultado de un crecimiento excesivo de tejido paratiroideo benigno, que afecta a una sola glándula o múltiples glándulas.

Objetivo del estudio:

  • Para proporcionar una visión general del hiperparatiroidismo primario.
  • Discutir los criterios de diagnóstico y las opciones de tratamiento.
  • Resaltar la importancia de las directrices quirúrgicas actualizadas y las estrategias de monitoreo.

Principales métodos:

  • Revisión de la literatura existente sobre el hiperparatiroidismo primario.
  • Análisis de las características clínicas y perfiles bioquímicos.
  • Evaluación de las recomendaciones diagnósticas y terapéuticas actuales.

Principales resultados:

  • El hiperparatiroidismo primario es causado con mayor frecuencia por un adenoma paratiroideo benigno único (80%) o por hiperplasia de glándulas múltiples (15-20%).
  • La enfermedad puede ser asintomática pero conlleva riesgos de pérdida ósea y cálculos renales.
  • Existe una variante con el calcio sérico normal pero con la hormona paratiroidea elevada.

Conclusiones:

  • La extirpación quirúrgica de las glándulas paratiroides afectadas ofrece una cura.
  • La selección de pacientes para la cirugía requiere el cumplimiento de las directrices actualizadas.
  • Los candidatos no quirúrgicos se benefician de un control regular del calcio sérico y la densidad ósea.
