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...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Urinary Tract Calculi I: Introduction

Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

Urinary Tract Calculi V: Nursing Management

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

Summary

Tumoral Calcinosis, a rare condition causing calcium deposits near joints, can mimic tumors. This case highlights its successful surgical treatment after diagnostic challenges.

Area of Science:

  • Orthopedics
  • Pathology
  • Radiology

Background:

  • Tumoral Calcinosis is a rare condition characterized by calcium deposits around joints, often mimicking neoplasms.
  • It typically affects the hip, shoulder, and elbow regions, posing diagnostic challenges.

Purpose of the Study:

  • To report a case of Tumoral Calcinosis presenting as a diagnostic enigma.
  • To emphasize the importance of pathological diagnosis and successful surgical management of this rare entity.

Main Methods:

  • Case presentation of a 25-year-old male with a two-year history of swelling in the axilla and hips.
  • Diagnostic workup including imaging and histopathological examination.
  • Surgical excision of the calcium deposits.

Monitoring Tumor Metastases and Osteolytic Lesions with Bioluminescence and Micro CT Imaging

Published on: April 14, 2011

Main Results:

  • The patient presented with gradually increasing swelling in the right axilla and both hips.
  • Initial presentation was a diagnostic challenge for the treating surgeons.
  • Histopathological examination confirmed Tumoral Calcinosis.
  • Successful surgical treatment was achieved.

Conclusions:

  • Tumoral Calcinosis requires a high index of suspicion due to its neoplastic appearance.
  • Multidisciplinary collaboration, particularly with pathology, is crucial for accurate diagnosis.
  • Surgical intervention is an effective treatment modality for symptomatic Tumoral Calcinosis.
