Synthesis and Functions of Calcitonin00:51

Synthesis and Functions of Calcitonin

4.0K
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...

Skin Cancer

5.6K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Changes in Skin Color: Clinical Perspectives

3.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Skin Diseases and Disorders

5.1K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

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...

Summary

Pediatric calcinosis cutis, a skin calcium deposition, is more common in males. Dystrophic and idiopathic types were most frequent, unlike adult cases lacking metastatic forms.

Area of Science:

  • Dermatology
  • Pediatric Medicine
  • Calcium Metabolism

Background:

  • Calcinosis cutis involves abnormal calcium deposition in the skin.
  • Limited data exists on pediatric calcinosis cutis.
  • Characterizing this condition in children is crucial.

Purpose of the Study:

  • To characterize calcinosis cutis in a pediatric cohort.
  • To identify demographic and etiological patterns.
  • To compare pediatric findings with adult data.

Main Methods:

  • Retrospective cohort study.
  • Single-institution analysis.
  • 5.5-year study period.

Main Results:

  • Thirty pediatric cases identified.
  • More common in males (63%) with earlier onset (median 5 years vs. 10 years for females).
  • Dystrophic (43%) and idiopathic (37%) calcinosis cutis were most prevalent; no metastatic cases observed.

Conclusions:

  • Pediatric calcinosis cutis etiology resembles adults, excluding the metastatic form.
  • Laboratory testing may be less critical for diagnosis than previously thought.
  • Further research into pediatric calcinosis cutis is warranted.
