Meiosis vs. Mitosis02:57

Meiosis vs. Mitosis

Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...
The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Urinary Tract Calculi I: Introduction01:28

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 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
This summary is machine-generated.

Renal malformations are common in Turner syndrome (TS), particularly in nonmosaic 45,X karyotypes. Routine kidney screening is vital for all TS patients to detect structural and collecting system abnormalities.

Area of Science:

  • Nephrology
  • Genetics
  • Pediatrics

Background:

  • Turner syndrome (TS) is a chromosomal condition affecting females, often associated with various health issues.
  • Renal malformations are a known complication of TS, but their prevalence varies with karyotype.
  • Understanding these variations is crucial for targeted screening and management.

Purpose of the Study:

  • To investigate the frequency and types of renal malformations in Turkish patients with Turner syndrome.
  • To compare the prevalence of renal abnormalities between nonmosaic 45,X and mosaic/structural X Turner syndrome.
  • To highlight the importance of routine nephrological screening in all TS patients.

Main Methods:

  • Evaluation of 82 Turkish patients diagnosed with Turner syndrome.
  • Classification of patients into nonmosaic 45,X (Group A) and mosaic/structural X (Group B) groups.
  • Renal ultrasonography performed on all patients to identify malformations.

Main Results:

  • 37.8% of TS patients exhibited renal malformations.
  • Higher prevalence of renal malformations in Group A (51.1%) compared to Group B (21.6%).
  • Horse-shoe kidney predominantly seen in Group A, while collecting system malformations were more frequent in Group B.

Conclusions:

  • All Turner syndrome patients require routine nephrological screening at diagnosis.
  • Nonmosaic 45,X TS is linked to a higher risk of structural kidney malformations.
  • Mosaic/structural X forms of TS are more associated with collecting system abnormalities, increasing UTI and hypertension risk.
