Summary
Primary hyperparathyroidism, a condition causing high calcium, is rarely diagnosed in pregnancy but can lead to miscarriage. Early detection and treatment of hypercalcemia improve pregnancy outcomes and prevent fetal loss.
Area of Science:
- Endocrinology
- Obstetrics & Gynecology
- Reproductive Medicine
Background:
- Primary hyperparathyroidism (PHPT) is a common endocrine disorder, infrequently diagnosed during pregnancy.
- PHPT can manifest as hypercalcemia, a condition associated with an increased risk of miscarriage.
- Recurrent miscarriages may be linked to undiagnosed hypercalcemia, necessitating thorough evaluation.
Purpose of the Study:
- To highlight the importance of evaluating calcium levels in patients with recurrent miscarriages.
- To emphasize the potential benefits of early hypercalcemia detection and management in pregnancy.
- To present a case study illustrating successful management of PHPT in pregnancy.
Main Methods:
- Case report of a 39-year-old woman presenting with infertility and elevated calcium and parathyroid hormone (PTH) levels.
- Diagnostic workup included neck ultrasound to identify parathyroid adenoma.
- Treatment involved parathyroidectomy to remove the adenoma.
Main Results:
- The patient was diagnosed with PHPT due to an upper left parathyroid gland adenoma.
- Post-parathyroidectomy, serum calcium levels normalized.
- The patient subsequently achieved a successful pregnancy and delivered a healthy baby.
Conclusions:
- Routine evaluation of serum calcium levels should be considered in the management protocol for recurrent miscarriages.
- Early identification and treatment of hypercalcemia can significantly improve pregnancy outcomes.
- Prompt management of PHPT mitigates risks of pregnancy loss and associated complications.

The Parathyroid Glands
2.3K
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...

Skeleton and Calcium Homeostasis
4.6K
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 Remodeling
38.4K
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.

Hormones and Bone Tissue
2.8K
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...

Infertility in Females
359
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.

Ovarian Cycle
1.5K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...
