Pericarditis II: Clinical Features and Diagnostic Tests

219
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Pericarditis I: Introduction

216
Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

The Parathyroid Glands00:59

The Parathyroid Glands

4.1K
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...

Pericarditis III: Medical Management

216
The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...

Pericarditis IV: Nursing Management

246
Pericarditis, an inflammation of the pericardium, necessitates diligent nursing management to ensure effective patient care and recovery. The initial step in managing pericarditis is a comprehensive patient medical assessment.The patient reports chest pain aggravated by breathing, coughing, and swallowing, which worsens when lying supine. The pain often improves when sitting up and leaning forward. Additional symptoms may include fever, malaise, and, in severe cases, signs of heart failure.

Summary

This is the first reported case of parathyroid carcinoma (PTCA) found within the pericardium. Successful surgical removal of this rare ectopic PTCA led to normalization of calcium and parathyroid hormone levels.

Area of Science:

  • Endocrinology
  • Cardiovascular Surgery
  • Oncology

Background:

  • Ectopic parathyroid glands are a common cause of persistent hyperparathyroidism after surgery.
  • Parathyroid carcinoma (PTCA) is a rare malignancy, and its ectopic occurrence is exceptionally uncommon.

Observation:

  • A 53-year-old female presented with symptoms of hypercalcemia and hyperparathyroidism, including bone pain, fractures, and cardiac issues.
  • Imaging revealed an ectopic mass in the mediastinum, later identified as intrapericardial via cardiac MRI.
  • The patient exhibited severe hypercalcemia (3.70 mmol/L) and elevated parathyroid hormone levels (>1900 pg/ml).

Findings:

  • Surgical resection via sternotomy successfully removed the intrapericardial parathyroid carcinoma.
  • Histopathology confirmed the diagnosis of PTCA.
  • Post-operative normalization of calcium, phosphorus, and parathyroid hormone levels was achieved.

Implications:

  • This case highlights the diverse ectopic locations parathyroid glands can present in.
  • It underscores the importance of considering ectopic parathyroid carcinoma in patients with primary hyperparathyroidism.
  • Accurate preoperative localization and en bloc resection are crucial for successful treatment of primary hyperparathyroidism.
